Description

Ascending control channel transmission and method of reseptance and equipment
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of ascending control channel transmission and method of reseptance and equipment.
Background technology
As shown in Figure 1, at Long Term Evolution Long Term Evolution, LTE) in system, in each wireless sub-frame, send Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH), the Physical Downlink Shared Channel of PDCCH and transmitting downlink data (PDSCH) forms the multiplexing relation of time division multiplexing (Time Division Multiple, TDM).Top n OFDM (Orthogonal Frequency Division Multiplexing, OFDM) symbol by a descending sub frame sends PDCCH, 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.
Long-term evolution upgrading (LTE-Advanced) system continues studying in evolution process the transmission plan of the multi-user multi-antenna (Multiple-user MIMO, MU-MIMO) of cooperative multipoint transmission (COMP) and enhancing.Wherein a kind of of COMP may scene be long-distance radio frequency unit (the Remot Radio Head of a macro base station and a plurality of distributions, RRH) from forming in logic the coverage of ，Ze Gai community, Yi Ge community and the number of users of access all increases greatly than original LTE system.Meanwhile, being widely used of the MU-MIMO of enhancing increases the number of users of service in community greatly.Therefore the capacity of PDCCH is had higher requirement, existing LTE PDCCH design can not be satisfied the demand.
For solution PDCCH is as mentioned above resource-constrained and the problem of off-capacity, a solution is in the PDSCH region in a descending sub frame, to send the PDCCH(Enhanced PDCCH strengthening, E-PDCCH), as shown in Figure 2, traditional PDCCH is called Legacy PDCCH.
At LTE version 11(Rel-11) E-PDCCH determined in discussing E-PDCCH support frequency domain continuously (localized) transmission and frequency domain distribution formula (distributed) transmit two kinds of patterns, be applied to different scenes.Generally, localized transmission mode is used for the comparatively accurate channel information that base station can obtain terminal feedback, and it is not very violent scene that adjacent cell is disturbed with subframe variation, now base station is this terminal transmission E-PDCCH according to the good cline frequency resource of the channel condition information of terminal feedback (CSI) selection quality, and carries out precoding/beam forming processing to improve transmission performance.At channel information, can not accurately obtain, or adjacent cell is disturbed with subframe and is changed in violent and unpredictable situation, need to adopt distributed transmission mode transmission E-PDCCH, in frequency of utilization, discontinuous frequency resource is transmitted, thereby obtains frequency diversity gain.
In LTE system, when the PDSCH that use Physical Uplink Control Channel (PUCCH) form (format) 1a/1b transmission is dispatched by PDCCH or the corresponding acknowledgement/non-acknowledgement of PDCCH (ACK/NACK) information of indicating the release of semi-continuous scheduling (SPS) resource, the PUCCH resource number that its correspondence is used
Figure BDA00001798194600021
according to the CCE numbering that PDCCH is shared, determine.Such design can effectively reduce PUCCH resource reserved in system, the quantity of the dynamic PUCCH resource of reserved maximum equals the maximum quantity of descending PDCCH, and need to not reserve for maximum number of user amount in community, conventionally the maximum quantity of PDCCH is much smaller than the number of users in community.
