Description
Technical field

Background technology
At present LTE(Long Term Evolution, Long Term Evolution) and LTE-A(Long Term Evolution-Advanced, long-term evolution upgrading) in the system, control channel PDCCH(physical downlink control channel, Physical Downlink Control Channel) can only be in preceding several symbol transmission of a subframe, the user obtains its schedule information by carry out blind check in the PDCCH resource.In order to satisfy ever-increasing dispatch demand, need to consider that certain methods strengthens control channel, the raising capacity is to support more user's scheduling, wherein a kind of method is similar Relay(relaying) the control channel method for designing of system.
Fig. 1 is the PDCCH and the PDSCH(Physical Downlink Shared Channel of Relay system, physical down link sharing channel) structural representation, PCFICH is Physical Control Format Indicator Channel (Physical Control Format Indicator Channel) among the figure.The PDCCH of Relay system and PDSCH resource structures figure as shown in Figure 1, R-PDCCH(relaying-PDCCH) be used for the base station wherein to the Relay control channel, the R-PDSCH(relaying-PDSCH) being used for the base station transmits data to Relay.After Relay receives control signal demodulation goes out R-PDSCH, use PDCCH and PDSCH again to UE(User Equipment, subscriber equipment) control channel and data.Wherein R-PDCCH and R-PDSCH take the resource that originally is used to transmit PDSCH.
In R-PDCCH,, then can only adopt CRS(Cell-specific reference signals, the exclusive pilot signal in sub-district if adopt interweaving method) demodulation; If adopt the non-mode that interweaves, then Relay can also can use DMRS(demodulation reference signal, demodulated reference signal with CRS) carry out demodulation, dispose the method for its demodulation by high-level signaling by the base station.When separating timing with DMRS, can only adopt the scramble sequence of port 7 and scrambling ID=0, do not support a plurality of users to adopt quadrature DMRS to carry out multiplexing transmission.Wherein first time slot of R-PDCCH is used to transmit down dispatch information, and second time slot is used to transmit uplink scheduling information.The base station notifies its control signaling of each Relay shared physical resource by high-level signaling, obtains its control information thereby Relay carries out blind check on corresponding resource.Because do not transmit PDCCH this moment simultaneously, so Relay only needs blind check R-PDCCH to get final product.
