OUT-OF-GROUP INTERFERENCE MEASUREMENT IN WIRELESS COMMUNICATION SYSTEMS

摘要

A communications network comprises a group of two or more in-group antennas associated with one or more base stations and a user equipment, wherein the in-group antennas are arranged to co-operate in downlink transmission to the user equipment; transmission from the in-group antennas is co-ordinated so that their downlink transmission in particular transmission resources is muted; and wherein the user equipment is configured to measure a downlink channel in the muted transmission resources.
