Abstract

Provided are a method and device for reporting the reference signal receiving power. The method comprises: a base station determining at least one first channel-state information reference signal CSI-RS resource used for a terminal to report the reference signal receiving power RSRP, the first CSI-RS resource containing at least one antenna port group, the antenna port group containing at least one antenna port; the base station sending first CSI-RS resource configuration information to the terminal, the first CSI-RS resource configuration information carrying at least one first CSI-RS resource; and the base station receiving the RSRP of each antenna port group contained in the first CSI-RS resource reported by the terminal. The embodiments of the present invention achieve the purpose of saving the overhead for reporting the RSRP.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method and device for reporting received power of a reference signal. Background technique [0002] In a Coordinated Multiple Point Transmission and Reception (CoMP) system, one or more access points (Access Point, AP) transmit data for a user equipment (User Equipment, UE), or receive data transmitted by the UE. The UE needs to measure and report the channel state information (Channel-State Information, CSI) of one or more access points to the base station, and the reference signal used to measure the CSI is a channel state information reference signal (Channel-State Information Reference Signal, CSI- RS). Usually, the UE also needs to measure and report the Reference Signal Receiving Power (RSRP) to the base station. The base station needs to determine the set of access points that provide services for the UE according to the RSRP reported by the UE, or determine the set o...
