Abstract

The embodiment of the invention discloses an interference measurement indication method, an interference measurement method, related equipment and a communication system. One of the interference measurement indication methods includes: the base station sends at least one piece of channel state information reference signal CSI-RS configuration signaling of the first type to the user equipment UE, and the at least one type of CSI-RS configuration signaling indicates that it is used to send CSI The first resource set of ‑RS; the base station sends at least one second type of CSI‑RS configuration signaling to the UE, and the second resource for sending CSI‑RS indicated by the at least one second type of CSI‑RS configuration signaling The set is a subset of the first set of resources. The technical solutions provided by the embodiments of the present invention are beneficial to improving the flexibility of UE interference measurement.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an interference measurement indication method, an interference measurement method, related equipment and a communication system. Background technique [0002] In order to enable user equipment (UE, User Equipment) to measure downlink channel state information (CSI, Channel State Information) in a wireless communication system, the base station needs to send a reference signal to the user equipment in its coverage area so that the user equipment can measure the downlink channel. [0003] For example, the 3rd Generation Partnership Project (3GPP, the 3rd Generation Partnership Project) Long Term Evolution (LTE, Long Term Evolution) R10 protocol stipulates that the base station needs to send a channel state information reference signal (CSI-RS, Channel State Information Reference signal) To measure the downlink channel for the UE in its coverage area, at this time, the base st...
