Description

Uplink feedback information sending and receiving method, system and equipment

Technical field

The present invention relates to wireless communication field, relate in particular to a kind of uplink feedback information sending and receiving method, system and equipment.

Background technology

In Long Term Evolution (LTE) system, in the control area of wireless sub-frame, send Physical Downlink Control Channel (PDCCH), in the data area of wireless sub-frame, send Physical Downlink Shared Channel (PDSCH), PDCCH and PDSCH form the multiplexing relation of time division duplex (TDM), as shown in Figure 1.PDCCH sends by the top n OFDM symbol of a descending sub frame, and wherein the possible value of N is 1,2,3 or 4, and N=4 only allows to appear in the system that system bandwidth is 1.4MHz.

Long-term evolution upgrading (LTE-Advanced) system continues studying coordinated multipoint transmission (Coordinated Multiple Point in evolution process, COMP) and the scheme of the multi-user's Multiinputoutput (Muti-User-MIMO, MU-MIMO) that strengthens transmission.Wherein a kind of of COMP may scene be long distance wireless node (the Remot Radio Head of a macro base station and a plurality of distributions, RRH) from the coverage that forms in logic ，Ze Gai residential quarter, a residential quarter and the number of users of access, all than original LTE system, greatly increase.Simultaneously, being widely used of the MU-MIMO of enhancing makes the number of users of service in residential quarter greatly increase.Therefore the capacity of PDCCH is had higher requirement, existing LTE PDCCH design can not be satisfied the demand.

For solution PDCCH as mentioned above is resource-constrained and the problem of off-capacity, a solution is in the PDSCH zone in a descending sub frame, take Physical Resource Block (PRB) as unit, to send the PDCCH(Enhanced PDCCH that strengthens), as shown in Figure 2, traditional PDCCH is called Legacy PDCCH.

At present, the search volume design that a kind of resource based on Enhanced PDCCH bunch (Enhanced PDCCH cluster) arranged for the PDCCH structure of above-mentioned enhancing, be about to a plurality of continuous PRB to dividing an Enhanced PDCCH cluster into, as shown in Figure 3, Figure 4, a PDCCH of terminal (UE) can only transmit in an Enhanced PDCCH cluster.In Enhanced PDCCH cluster, can only transmit the PDCCH of a UE, also can transmit the PDCCH of a plurality of UE.UE transmits the PRB position that PDCCH occupies in an Enhanced PDCCH cluster relevant with the polymerization grade.

In the LTE system for descending dynamic dispatching (DL grant), Physical Uplink Control Channel (PUCCH) resource that its corresponding acknowledgement/non-acknowledgement (ACK/NACK) feedback information uses is to determine according to the parameter of the shared resource number of PDCCH and high-rise configuration.Such mode can effectively reduce PUCCH resource reserved in system, the maximum quantity that the quantity of the dynamic PUCCH resource of maximum of namely reserving equals descending PDCCH gets final product, and need to not reserve for maximum number of user amount in residential quarter, usually the maximum quantity of PDCCH is much smaller than the number of users in residential quarter.

In realizing process of the present invention, the inventor finds in prior art to exist following technical problem:

In existing disclosed technology, when using the PDCCH that strengthens to carry out descending dynamic dispatching, the UE how to confirm transmits the PUCCH resource that ACK/NACK feedback information corresponding to this descending dynamic dispatching uses, there is no at present concrete implementation, and then make UE can't transmit the ACK/NACK feedback information corresponding to PDCCH of enhancing.
