A RADIO BASE STATION AND A METHOD THEREIN FOR SCHEDULING UPLINK RESOURCES

摘要

A radio base station (RBS) and a method performed by an RBS for scheduling uplink resources to at least one UE are provided. The RBS comprises at least two receiving antenna branches and the RBS is operable in a radio communication network. The method comprises receiving transmissions from the at least one UE by means of the at least two receiving antenna branches; and determining at least one parameter relating to signal quality of the received transmissions. The method further comprises determining a diversity gain of the at least two receiving antenna branches, wherein the diversity gain is determined based on the determined parameter(s); and scheduling uplink transmissions for the at least one UE based on the determined diversity gain.
