摘要:
The disclosure relates to methods and devices for notifying and determining common reference signal (CRS) patterns. The notification method comprises the steps of transmitting first downlink control information (DCI) to user equipment (UE) to inform the UE an aperiodic channel status information (CSI) feedback set and a CoMP transmission scheme to be applied to the UE, wherein the CoMP transmission includes a plurality of possible combinations of transmission points that transmit PDSCH to the UE; and transmitting second DCI to the UE for notifying transmission parameter to the UE based on the first DCI. In the disclosure, all CoMP transmission schemes and notifications of all CRS patterns therein can be supported, thus effectively perfecting notifications of the CRS patterns, saving signaling overheads, and significantly improving the flexibility.
