Abstract:
1. A method, comprising: receiving a higher-layer configuration for reference signal received power (RSRP) measurement from a downlink transmission point by a user equipment (UE) for serving point selection in a coordinated multi-point operating (CoMP) mobile network having a plurality of points, wherein the higher-layer configuration contains multiple Channel State Information Reference Signal (CSI-RS) configurations, and wherein each CSI-RS configuration indicates a set of resource elements (REs) or subcarriers in both frequency domain and time domain as one CSI-RS resource with non-zero transmission power; identifying a CSI-RS configuration corresponding to a macro-eNB from the multiple CSI-RS configurations; performing RSRP measurements based on the multiple CSI-RS configurations; and reporting RSRP measurement results to one or multiple uplink receiving points based on the RSRP measurements.
