Description

Ascending control channel transmission and method of reseptance and equipment

Technical field

The present invention relates to wireless communication field, particularly relate to the transmission of a kind of ascending control channel and method of reseptance and Equipment.

Background technology

As it is shown in figure 1, at Long Term Evolution Long Term Evolution, LTE) in system, in each nothing In line subframe send Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH), PDCCH forms the time-division with the Physical Downlink Shared Channel (PDSCH) of transmission downlink data The multiplexing relation of multiplexing (Time Division Multiple, TDM).By the front N of a descending sub frame Individual OFDM (Orthogonal Frequency Division Multiplexing, OFDM) symbol is sent out Sending PDCCH, wherein possible for N value is 1,2,3,4, and N=4 only allows to occur in system bandwidth and is In the system of 1.4MHz.

Long-term evolution upgrading (LTE-Advanced) system continues to study coordinate multipoint in evolution process and passes The multi-user multi-antenna (Multiple-user MIMO, MU-MIMO) of defeated (COMP) and enhancing Transmission plan.Wherein a kind of possible scene of COMP is the remote radio frequency of a macro base station and multiple distributions Unit (Remot Radio Head, RRH) logically constitutes a community, the coverage of Ze Gai community And the number of users accessed all is greatly increased than original LTE system.Meanwhile, the MU-MIMO of enhancing Be widely used so that in community service number of users be greatly increased.Therefore the capacity of PDCCH is proposed Higher requirement, existing LTE PDCCH design can not meet needs.

Limited and the problem of off-capacity, a solution for solution PDCCH resource as mentioned above It is the PDCCH(Enhanced PDCCH sending enhancing in the PDSCH region in a descending sub frame, E-PDCCH), as in figure 2 it is shown, traditional PDCCH is referred to as Legacy PDCCH.

At LTE version 11(Rel-11) E-PDCCH discuss in have determined that E-PDCCH support frequency domain (localized) transmission and frequency domain distribution formula (distributed) transmit both of which continuously, are applied to difference Scene.Under normal circumstances, localized transmission mode is used for base station and is obtained in that terminal feedback is more The interference of channel information, and adjacent cell accurately is not the most violent scene, now base station root with subframe change Quality preferable cline frequency resource is selected to be that this terminal passes according to the channel condition information (CSI) of terminal feedback Defeated E-PDCCH, and carry out precoding/beam forming processing to improve transmission performance.Can not at channel information Accurately obtain, or adjacent cell interference with subframe change violent and unpredictable in the case of, need to use Distributed transmission mode transmission E-PDCCH, i.e. uses discontinuous frequency resource in frequency to be transmitted, Thus obtain frequency diversity gain.

In LTE system, Physical Uplink Control Channel (PUCCH) form (format) 1a/1b is used to pass The defeated PDSCH dispatched by PDCCH or the PDCCH institute of instruction semi-continuous scheduling (SPS) resource release During corresponding acknowledgement/non-acknowledgement (ACK/NACK) information, the PUCCH that its correspondence is used Resource number Number according to the CCE shared by PDCCH and determine.Such design can be effective PUCCH resource reserved in reduction system, the quantity of i.e. reserved maximum dynamically PUCCH resource is equal to The maximum quantity of descending PDCCH, reserves without for maximum number of user amount in community, Generally the maximum quantity of PDCCH is much smaller than the number of users in community.
