USER EQUIPMENT AND METHOD FOR ANTENNA PORT QUASI CO-LOCATION SIGNALING IN COORDINATED MULTI-POINT OPERATIONS

摘要

PROBLEM TO BE SOLVED: To provide user equipment (UE) and methods for antenna port quasi co-location signaling in coordinated multi-point (CoMP) operations.SOLUTION: Downlink channels are at least partially offloaded from a serving evolved Node B (eNB) to neighbor eNBs. The UE receives signaling from the serving eNB to indicate a reference signal of a neighbor eNB to use for estimation of large-scale physical-layer parameters associated with the downlink channels provided by the neighbor eNB. The UE estimates the large-scale physical-layer parameters on the basis of receipt of the indicated reference signal from the neighbor and serving eNBs, and applies them for processing the downlink channels from the neighbor and serving eNBs.SELECTED DRAWING: Figure 5
