Description

Channel monitoring control method, device and user terminal

technical field

In order to reduce the power consumption of the user terminal, the Discontinuous Reception (DRX) technology was introduced in Long Term Evolution (LTE for short), that is, when the user terminal has no data transmission, it enters the sleep state and turns off the transceiver unit to achieve The purpose of reducing power consumption.

The DRX cycle of the user terminal includes the time when the user terminal is in the DRX on state, that is, the active state, and the time when the user terminal is in the DRX off state, that is, the sleep state. When the user terminal is in the DRX on state, the user terminal monitors the physical downlink control channel (Physical Downlink Control Channel, referred to as PDCCH), the base station can send a DRX instruction to the user terminal through the Media Access Control (Media Access Control, referred to as MAC) control information unit (Control Element, referred to as CE), so that the user terminal stops monitoring the PDCCH channel, And enter the DRX off state in advance.

However, MAC CE can only be placed in the MAC packet header of the downlink data and sent to the user terminal. Therefore, the DRX command can only be carried in the last downlink data and sent to the user terminal. If the user terminal is in the DRX on state, the base station has no downlink If the data is to be sent to the user terminal, the base station cannot issue DRX commands to the user terminal, and the user terminal cannot enter the DRX off state in advance, and can only continuously monitor the PDCCH channel, resulting in increased power consumption of the user terminal.

The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

Fig. 1 is a flow chart of Embodiment 1 of a channel monitoring control method according to an exemplary embodiment. The method can be executed by a channel monitoring control device, and the channel monitoring control device can be integrated in a user terminal (UserEquipment, UE for short). ), as shown in Figure 1, the method includes the following steps:

In step 101, the physical downlink control channel PDCCH is monitored.

In this embodiment, the user terminal has a Discontinuous Reception (DRX for short) function, that is, when the user terminal has no data transmission, it enters a sleep state and turns off the transceiver unit to reduce power consumption. The DRX cycle of the user terminal includes the time when the user terminal is in the DRX on state, that is, the active state, and the time that the user terminal is in the DRX off state, that is, the sleep state. When the user terminal is in the DRX on state, that is, the active state in the current DRX cycle, the user terminal monitors the base station A physical downlink control channel (Physical Downlink Control Channel, PDCCH for short) between the UE and the user terminal.

In step 102, a discontinuous reception DRX instruction issued by the base station through the PDCCH is received, and the DRX instruction is used to control the user terminal to stop monitoring the PDCCH.

In the embodiment of the present disclosure, optionally, the base station communicating with the user terminal is an evolved Node B (Evolved Node B, eNodeB for short) in Long Term Evolution (LTE for short), and the eNodeB sends a control message to the user terminal through a PDCCH channel. An instruction, optionally, the control instruction is a DRX instruction, and the DRX instruction is used to control the user terminal to stop monitoring the PDCCH channel.

In step 103, according to the DRX instruction, in the current DRX cycle, stop monitoring the PDCCH, and restart the DRX cycle.

In this embodiment, the user terminal continuously monitors the PDCCH channel. When the user terminal monitors the DRX instruction sent by the eNodeB in the PDCCH channel, it stops monitoring the PDCCH channel in the current DRX cycle, so that the user terminal enters the current DRX cycle in advance. The DRX off state is the sleep state. After the user terminal ends the DRX off state corresponding to the current DRX cycle, it enters the next DRX cycle and monitors the physical downlink control channel PDCCH again.

If the user terminal is in the inactivity state and has not timed out, it can still receive the data sent by the base station, for example, during t4. When the base station finishes sending data, or the user terminal is in the inactivity state for a timeout, the user terminal enters the DRX off state, that is, the sleep state, for example, during t5. After the DRX off state, that is, the t5 period ends, the user terminal enters the first state of the next DRX cycle T3, that is, the onduration state, for example, the t1 period in the DRX cycle T3.
