Description
Technical field
The present invention relates to wireless communication technology field, particularly a kind of method, system and equipment that sends and receive CSI.
Background technology
At LTE (Long Term Evolution, Long Term Evolution) in the system, PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) in each wireless sub-frame, sends, and with downlink data PDSCH (Physical Downlink Shared Channel, physical down link sharing channel) relation of formation TDM (Time Division Multiple, time division multiplexing) is shown in Figure 1A.PDCCH sends by top n OFDM (Orthogonal Frequency Division Multiplexing, the OFDM) symbol of a descending sub frame, and wherein the possible value of N is 1,2,3,4, and N=4 only allows to appear in the system that system bandwidth is 1.4MHz.
The control area of transmission PDCCH is to be made of the CCE (Control Channel Element, control channel unit) of logical partitioning in the LTE system, and wherein CCE has adopted the mode that interweaves fully to the mapping of RE (Resource Element, Resource Unit).DCI (Downlink Control Information, Downlink Control Information) it is unit that transmission also is based on CCE, a DCI at a UE (subscriber equipment) can send in N continuous CCE, the possible value of N is 1 in the LTE system, 2,4,8, be called CCE polymerization grade (Aggregation Level).UE carries out the PDCCH blind check in the control area, whether search exists the PDCCH at its transmission, RNTI (the Network Temporary Identifier of this UE is promptly used in blind check, Radio Network Temporary Identifier symbol) to the trial of decoding of different DCI forms and CCE polymerization grade, if decoding is correct, then receive DCI at this UE.LTEUE each descending sub frame in non-DRX (Discontinuous Reception, discontinuous reception) state all needs blind check is carried out in the control area, search PDCCH.
In LTE-A (Long Term Evolution-Advanced, long-term evolution upgrading) system,, PDCCH is strengthened in order further to improve demand to the PDCCH channel capacity.For the PDCCH that strengthens, present scheme is to send the PDCCH that strengthens in the PDSCH territory in descending sub frame when keeping original PDCCH territory.Original PDCCH still adopts existing transmission and reception technique in the territory, use original PDCCH resource, as adopt when sending and send diversity, during reception based on CRS (cell-specific reference signal, the cell-level reference signal) adopt the blind check technology DCI to be carried out blind check in common search space and the exclusive search volume of subscriber equipment, taking top n OFDM symbol sends, wherein the possible value of N is 1,2,3,4, and N=4 only allows to appear in the system that system bandwidth is 1.4MHz, this part PDCCH territory is called Legacy PDCCH territory.More advanced transmission and reception technique can be used in the PDCCH territory that strengthens, use the part resource of original PDSCH, as adopt precoding when sending, during reception based on user-specific reference signal (UE-Specific Reference Signal, UE-RS), also be DMRS (Demodulation Reference Symbol, demodulation reference mark) detects, taking Legacy PDCCH territory running time-frequency resource in addition sends, this part PDCCH territory is called Enhanced PDCCH territory (the i.e. PDCCH of Zeng Qianging, E-PDCCH), shown in Figure 1B.
The employed resource location of P PDSCH can be indicated by the DCI among the PDCCH, and for the PDCCH that strengthens, a kind of method is to indicate the employed resource location of E-PDCCH by high-level signaling.Because the mutual cycle of high-level signaling is longer,, then can make E-PDCCH can't fully obtain the frequency selectivity gain if by the definite E-PDCCH resource location of high-level signaling indication.So generally speaking, high-level signaling can distribute one group of available resources for E-PDCCH, and the part resource can be selected for E-PDCCH based on the channel condition information that UE fed back in the base station in the available resources scope of high level configuration in transmission.When UE carries out the reception of E-PDCCH resource, can in the available resources scope of high level configuration, carry out the E-PDCCH blind Detecting.Thereby obtain the compromise of the blind check complexity and the scheduling degree of freedom.
CSI (Channel State Information, channel condition information) is used to make network side can understand the state of respective channels, thereby carries out respective handling.No matter be PDSCH, E-PDCCH or other channels, corresponding CSI all can be arranged, but also do not have the scheme of a kind of CSI of reporting at present.
In sum, the scheme that does not also have a kind of CSI of transmission at present.
