The uplink transmission method, the configuration method, the device, the terminal and the network side equipment provided by the embodiment of the application are described in detail through some embodiments and application scenes thereof by combining the attached drawings.

Referring to fig. 2, fig. 2 is a flowchart of an uplink transmission method provided in an embodiment of the present application, where the method is performed by a terminal, and as shown in fig. 2, the method includes the following steps:

And step 21, the terminal acquires the time domain pattern.

Optionally, the time domain pattern indicates the positions of uplink timeslots of at least two cells. The time domain pattern may be configured by the network side device for the terminal, or may be preset based on actual requirements, which is not limited.

And step 22, the terminal determines a target cell in at least two cells according to the time domain pattern.

Optionally, the target cell may include, but is not limited to, a primary cell Pcell, a primary secondary cell PScell, and/or a secondary cell Scell for PUCCH, etc. The network side device can configure a target cell for the terminal through the time domain pattern based on actual conditions.

And step 23, the terminal performs PUCCH transmission on the target cell.

Note that this embodiment preferably has only one PUCCH transmission at a time. The scenarios to which the present embodiment is adapted include, but are not limited to, single carrier, dual connectivity, carrier aggregation, etc.

According to the uplink transmission method provided by the embodiment of the application, after the terminal acquires the time domain pattern, the target cell can be determined according to the time domain pattern, and PUCCH transmission is performed on the target cell. Therefore, by means of the time domain pattern, the network side equipment can flexibly configure the target cell for PUCCH transmission, so that PUCCH transmission delay is reduced, and the reliability of PUCCH transmission is improved.

In some embodiments, PUCCH transmission of the terminal is used to carry hybrid automatic repeat request acknowledgement (HARQ-ACK) information for HARQ-ACK feedback. Therefore, by means of the scheme in the application, the time delay of HARQ-ACK feedback can be reduced, thereby being beneficial to the transmission of low-delay service.

In some embodiments, the network side device may configure one or more target cells for the UE, where the target cells are not limited to Pcell, PScell, PUCCH Scell, or the like. The network side device may configure a time domain pattern for the UE, for indicating a target cell for PUCCH transmission by the UE.

Notably, the network side device may configure PUCCH resources on both target cells. The PUCCH resource may be configured independently for each cell, or the target cell may be configured in the same PUCCH with other cells in the same cell group, for example, a Pcell, a PScell, and/or a PUCCH SCell.

In one embodiment, PUCCH resources are configured independently for each cell, such as shown in table 1 below, PUCCH configurations on Pcell, PScell, and/or PUCCH Scell are configured independently from PUCCH configurations on target cells, note that target cells of table 1 represent cells other than Pcell, PScell, and PUCCH Scell.

TABLE 1

In another embodiment, the PUCCH resources are configured identically for all cells, such as shown in table 2 below, the PUCCH configuration on Pcell, PScell and/or PUCCH Scell is configured identically to the PUCCH configuration on the target cell, note that the target cell of table 2 represents other cells except for Pcell, PScell and PUCCH Scell.

TABLE 2

Optionally, the configuration parameters of the time domain pattern may include at least one of the following of the target cell:

cell index;

a cell pattern indicating a position of an uplink slot of a corresponding cell;

The starting position of the target cell may include, but is not limited to, a starting radio frame, a starting subframe, a starting slot, a starting symbol, etc.;

duration of time;

a cell configuration period;

The subcarrier spacing is, for example, 15kHz or 30 kHz;

The time domain granularity is slot granularity or sub-slot granularity, for example.

In a time domain pattern configuration of a target cell, the time domain pattern may include parameters of { cell index, CELL PATTERN, start position, cell configuration period, subcarrier spacing, time domain granularity }, of the target cell.

In another time domain pattern configuration of the target cell, the time domain pattern may include parameters of { cell index, cell configuration period, CELL PATTERN (cell 1, cell 2., cell n), duration, subcarrier spacing, starting position, time domain granularity }, of the target cell. Wherein CELL PATTERN (cell 1, cell2,.. Celln) represents the cell order of n cells in the time domain pattern. The duration is the length of time each cell has on CELL PATTERN.

In some embodiments, if the time domain pattern configured by the network side device for the terminal includes an index of the target cell, the terminal may directly determine the corresponding target cell according to the index.

In some embodiments, when configuring a target cell for a terminal, the network side device may ensure that only one target cell corresponds to an uplink UL resource on the time domain pattern at a certain moment.

In some embodiments, if the network side device configures multiple target cells at one time, the terminal may determine one target cell according to a predefined rule or a higher layer parameter. For example, the predefined rule is to select the target cell with the smallest or largest cell index. In addition, the terminal may also determine the target cell according to a higher layer parameter, for example, determine the target cell according to a time domain granularity.

Alternatively, when the terminal determined according to the time domain pattern has a plurality of target cells at one time, such as the current time, the terminal may determine one target cell from the plurality of target cells according to a predefined rule. For example, the predefined rule is to select the target cell with the smallest or largest cell index. In addition, the terminal may also determine the target cell according to a higher layer parameter, for example, determine the target cell according to a time domain granularity.

Optionally, the cell pattern of the target cell is formed by any one of a first cell pattern, a second cell pattern and a third cell pattern. The first cell pattern is composed of at least one sub pattern, the second cell pattern is composed of a time slot configuration set, and the third cell pattern is composed of a cell set.

Optionally, each sub pattern may include at least one of:

for example, the sub pattern period P represents slot number;

the number of downlink DL time slots, the DL time slots comprise all DL symbols;

The number of downlink symbols in the flexible time slot;

the number of uplink UL slots, the UL slots including all UL symbols;

The number of uplink symbols in the flexible slot.

Optionally, in the first cell pattern mode, the period of the cell pattern is determined by the period of at least one sub pattern. For example, if a cell pattern is composed of 2 sub patterns, the period of the cell pattern is determined by the period of the 2 sub patterns, e.g., the period of the cell pattern is the sum of the periods of the 2 sub patterns.

Optionally, the above set of timeslot configurations for indicating the second cell pattern may include at least one of the following:

a set of time slots;

An index for each slot in the set of slots;

a set of symbols for each slot in the set of slots.

Further, the configuration of the symbol set of each slot may satisfy any one of the following:

the symbols in the symbol set are all downlink symbols;

the symbols in the symbol set are all uplink symbols;

the partial symbols in the symbol set are downlink symbols and the partial symbols in the symbol set are uplink symbols.

Alternatively, in the second cell pattern, the period of the cell pattern may be determined by the number of slots in the slot set of the slot configuration set. For example, if the number of slots in the slot set is 5, the period of the cell pattern is 5 slots.

Optionally, the third cell pattern is formed by a cell set, and represents the order of the target cells in the time domain pattern. For example, { cell2, cell3, cell1} indicates that the order of the target cell in the time domain pattern is cell2, cell3, cell1. At this time, the period of the time domain pattern needs to be separately configured. While the duration of each target cell needs to be configured separately.

In the embodiment of the application, the time domain pattern can be configured by the network side equipment for the terminal. The obtaining the time domain pattern may include:

The terminal receives configuration information from the network side equipment, wherein the configuration information is used for indicating a time domain pattern configured for the terminal. Thus, after receiving the configuration information, the terminal can determine the time domain pattern configured for the terminal according to the configuration information.

Optionally, the configuration information may be used to indicate at least one target cell configured for the terminal and a cell pattern of each target cell, and/or the configuration information may be used to indicate at least one target cell configured for the terminal and a cell pattern of at least one target cell.

Optionally, in the embodiment of the present application, the terminal may further receive indication information from the network side device, where the indication information is used to indicate a PUCCH resource allocated to the terminal and a slot where the PUCCH resource is located. Then, the terminal can determine the target cell according to the slot and the time domain pattern indicated by the configuration information, and feed back the PUCCH resource of the target cell.

Optionally, in the embodiment of the present application, when PUCCH transmission of the terminal is of a slot granularity, the terminal may select a target cell configured as a slot granularity according to a time domain pattern, and/or when PUCCH transmission of the terminal is of a sub-slot granularity, the terminal may select a target cell configured as a sub-slot granularity according to a time domain pattern.

Specific examples of the present application will be described below with reference to fig. 3 to 12.

Example 1

In this example 1, the network side device configures a target cell for the UE, where the target cell is not limited to a Pcell, a PScell, a PUCCH Scell, or the like, and configures a subcarrier spacing and CELL PATTERN of the target cell, and the CELL PATTERN is composed of a plurality of subparts. For example, the CELL PATTERN is composed of 1 sub-pattern, which is pattern1, or the CELL PATTERN is composed of 2 sub-patterns, which are sub-pattern 1 and sub-pattern 2.

As shown in fig. 3, the subpart 1 includes:

a subpattern period P1 (characterized by slot number);

The included symbols are all the slot numbers of the DL symbols, namely the DL slot numbers;

The number of DL symbols in the flexible slot;

The included symbols are all the slot number of the UL symbol, namely the UL slot number;

The number of UL symbols in the flexible slot.

The number of the flexible time slots is a value obtained by subtracting the number of the UL slots from the number of the DL slots which corresponds to the period P1.

Alternatively, whether flexible slots/symbols allow transmission of PUCCH may be configured by the network or determined by predefined rules.

As shown in fig. 3, the subpart 2 includes:

A subpattern period P2 (characterized by slot number);

the included symbols are all slots of the DL symbol;

The number of DL symbols in the flexible slot;

The included symbols are all slots of the UL symbol;

The number of UL symbols in the flexible slot.

Alternatively, if only 1 sub pattern such as sub pattern1 is configured, the period CELL PATTERN is the period of sub pattern1, i.e., P1. Or if only 2 sub patterns such as sub pattern1 and sub pattern2 are configured, then CELL PATTERN is the period after the period of sub pattern1 and sub pattern2, i.e., the sum of P1 and P2.

For example, referring to fig. 4, the target cell indexes are CC1 and CC2, CELL PATTERN of CC1 is DDDDD dduu, and CELL PATTERN of CC2 is DDDUU DDDDD. The UL resources for time domain pattern CELL PATTERN are union. The other slot resources are DL constructs, which are not available for UL PUCCH resources. Thus, the time domain pattern is DDDUUDDDUU, the subcarrier spacing is 15khz, slot 8 and slot 9 on CC1 (e.g., pcell) can be used to transmit PUCCH, slot 3 and slot 4 on CC2 can be used for PUCCH transmission, then either the UE will use CC2 if the network side device indicates that the UE is transmitting PUCCH at slot 3 or slot 4, or the UE will use CC1 if the network side device indicates that the UE is transmitting PUCCH at slot 8 or slot 9. Thus, since CC1 and CC2 are different component carriers (Component Carrier, CC), carrier switching of PUCCH can be achieved by this time-domain pattern configuration.

Further, in the slot diagram shown in fig. 4, slots available for PUCCH transmission are slot 8 and slot 9 on CC1 and slot 3 and slot 4 of CC 2.

Further, the network may configure a subcarrier spacing of 15kHz, configure CC2 as a target cell for transmitting PUCCH, and CELL PATTERN of CC2 is composed of 2 subparts, as shown in table 3 below:

TABLE 3 Table 3

Thus, by configuring two sub-patterns, pattern1 and pattern2, it is possible to determine the available slots or symbols for PUCCH transmission available on the target cell (CC 2), i.e. slot 3 and slot 4 on CC2 are available for PUCCH transmission.

In another configuration, the network may configure that the resources of the Pcell (PScell or PUCCH Scell) are always available for transmitting PUCCH, and CELL PATTERN may not contain an indication of the Pcell (PSCell or PUCCH Scell). As shown in fig. 5, CC1 is Pcell (PScell or PUCCH Scell), and only CELL PATTERN of CC2 is configured, and CELL PATTERN is composed of pattern1 and pattern 2.

Of course, the starting position CELL PATTERN shown in fig. 5 also needs to be configured, such as a starting radio frame position, a starting subframe position, a starting slot position, or/and a starting symbol position, etc. One simple configuration is to align with the UL-DL configuration of Time Division Duplexing (TDD) of the Pcell. In an alternative, the starting position CELL PATTERN is aligned with slot 0 of subframe 0 of radio frame 0 of the Pcell.

Example 2

In this example 2, the network side device configures a target cell for the UE, where the target cell is not limited to a Pcell, a PScell, a PUCCH Scell, or the like, and configures a subcarrier spacing and CELL PATTERN of the target cell, and the CELL PATTERN is indicated by a timeslot configuration set.

Wherein the time slot configuration set comprises:

1) A set of time slots;

2) An index for each slot in the set of slots;

3) A set of symbols for each slot in the set of slots.

Further, the symbol set of each slot may be configured to be a full downlink symbol number, a full uplink symbol number, or explicitly indicate the transmission direction of the symbols, i.e., that part of the symbols in the symbol set are downlink symbols and part of the symbols are uplink symbols.

Wherein the period of CELL PATTERN is determined by the number of slots contained in the set of slots. For example, there are m slots in the slot set, then the period of CELL PATTERN is m slots.

The flexible symbol number is a value obtained by subtracting the DL symbol number from the slot symbol number and subtracting the UL symbol number from the DL symbol number. Whether flexible symbols allow transmission of PUCCH may be configured by the network or determined by predefined rules.

Example 3

In this example 3, the network may simultaneously configure a plurality of target CCs and CELL PATTERN of each target CC. When carrier aggregation is configured, PUCCH transmission delay can be further reduced by configuring a plurality of CELL PATTERN if only one CELL PATTERN is configured, because PUCCH transmission delay cannot be completely reduced due to a difference in UL-DL configuration.

For example, as shown in fig. 6, the network may configure 3 target CCs, where the UL-DL ratio of CC1 is 7D1S2U, CELL PATTERN of the CCs is DDDDD DDDUU, CELL PATTERN of CC2 is DSUDDDSUDD, CELL PATTERN of CC3 is DDSUU DDDSD, the time domain pattern of CCs 1, CC2 and CC3 is DDUUU DDUUU, that is, the UL resources of different target cells are combined, and other time slots are regarded as DL.

In this case, the network may configure a set of { target cell index, CELL PATTERN } combinations for indicating candidate PUCCH transmission resources on multiple target cells.

For example, referring to table 4 below, the network may configure { target cell index, CELL PATTERN mode a, slot granularity, subcarrier spacing }, for the UE.

TABLE 4 Table 4

For another example, referring to table 5 below, the network may configure { target cell index, CELL PATTERN mode B, slot granularity, subcarrier spacing }, for the UE.

TABLE 5

For another example, referring to table 6 below, the network may configure { target cell index, CELL PATTERN patterns a or B, slot granularity, subcarrier spacing }, for the UE.

TABLE 6

For example, for the slot diagram shown in fig. 5, the following table 7 may be used for configuration.

TABLE 7

Note that the configuration shown in table 7 is a reference configuration for candidate PUCCH transmission, not an actual UL-DL configuration.

Example 4

In this example 4, the network may configure a plurality of target cells and one CELL PATTERN, and the CELL PATTERN is applied to all target cells. For example, referring to fig. 7, one CELL PATTERN, DDUUU DDUUU may be configured for CC1, CC2, and CC3, and it should be noted that in this case, CELL PATTERN of CC1, CC2, and CC3 is the time domain pattern. Wherein slot 8 and slot 9 on CC1 can be used to transmit PUCCH, slot 2 and slot 7 on CC2 can be used to transmit PUCCH, and slot 3, slot 4 and slot 9 on CC3 can be used to transmit PUCCH.

Alternatively, the network may ensure that the CELL PATTERN UL resources correspond to only one target cell at a time. If a certain time corresponds to a plurality of target cells, the UE may determine one target Cell according to a predefined rule or a higher layer parameter, and the predefined rule may be the target Cell with the largest Cell index.

Alternatively, the network may dynamically indicate a time slot of a PUCCH resource for the UE, and the UE determines a target cell according to the time slot of the PUCCH resource and CELL PATTERN. For example, if the slot of the PUCCH resource indicated by the network for the UE is slot 4, then CC3 is selected in combination with CELL PATTERN shown in fig. 6 because slot 4 of CC3 is UL resource.

Example 5

In this example 5, the effective UL symbol applied to CELL PATTERN of the target cell may be a subset of the UL resources available for configuration parameters of the target cell, such as tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated configurations.

For example, referring to fig. 8, the effective UL symbols applied on CELL PATTERN of CC2 and CC3 may be a subset of the UL resources available for the tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated configurations of the CC2 and CC 3. Wherein slot 2 and slot 7 on CC2 can be used for PUCCH transmission, and slot 3, slot 4 and slot 9 on CC3 can be used for PUCCH transmission.

Example 6

In this example 6, the network may configure CELL PATTERN on the target cell to be slot granularity or sub-slot granularity. For example, when 2 target cells are configured, CELL PATTERN of one cell may be slot granularity and the other CELL PATTERN sub-slot granularity.

For example, referring to fig. 9, CELL PATTERN of CC1 and CC2 may be configured to be slot granularity, CELL PATTERN of CC3 may be configured to be sub-slot granularity. If the granularity of the HARQ-ACK codebook that needs feedback at time 1 is slot, the UE may select CC1 or CC2 for HARQ-ACK feedback based on the configured CELL PATTERN. Or if the granularity of the HARQ-ACK codebook that needs to be fed back at time 2 is sub-slot, the UE may select CC3 for HARQ-ACK feedback based on the configured CELL PATTERN.

Example 7

In this example 7, CELL PATTERN configured by the network for the UE is configured in the third cell pattern mode. The network may configure 3 target cells, CC1, CC2, and CC3, for the UE, with the corresponding UL-DL configuration as shown in fig. 10. The period of the time domain pattern configured by the network for the UE is assumed to be 40ms, the subcarrier interval is 15kHz,cell pattern { cell2, cell3, cell1}, the target cell at the time t1 is cell2, and the duration is 10ms. the target cell at time t2 is cell3, with a duration of 10ms. the target cell at time t3 is cell1, with a duration of 20ms. Thus, as shown in fig. 11, at time t1-t2, the time domain pattern is UL-DL configuration of cell2, the UE will use UL resources of cell2 for PUCCH feedback, at time t2-t3, the time domain pattern is UL-DL configuration of cell3, the UE will use UL resources of cell3 for PUCCH feedback, at time t3-t4, the time domain pattern is UL-DL configuration of cell1, the UE will use UL resources of cell1 for PUCCH feedback.

Alternatively, the period of the time domain pattern of the network configuration may be greater than the period of CELL PATTERN of the configuration, as shown in fig. 12, where CELL PATTERN of the configuration is { cell2, cell3}, duration {10ms,10ms }. For a time period of one time domain pattern, which is not configured CELL PATTERN, a cell that is predefined or configured may be used as a target cell, for example, a Pcell.

Alternatively, within a cell group, the network may configure a time domain pattern that applies to the entire cell group.

Alternatively, the network may configure a time domain pattern for each target cell.

Alternatively, the network may configure whether each target cell is based on slot granularity or sub-slot granularity.

In an alternative embodiment, the configuration period of the time domain pattern may be radio frame alignment.
