Abstract:
Method for use in a wireless telecommunications system (1) having at least one user equipment (UE) (10) and a plurality of base stations (20,22,24) connected to a common network controller (76), wherein said UE is able to periodically determine the magnitude of at least one parameter of plural radio downlinks (14,16,18) simultaneously established from more than one of said plurality of base stations to said UE in order to periodically decide which one of said more than one of said plural radio downlinks is from a currently preferred base station for use in a communications session between said UE and an end terminal in communication with said system, comprising the steps of:periodically signaling on an uplink (60) from said UE to at least one of said more than one of said plurality of base stations that a dedicated downlink to said UE from said at least one of said more than one of said plurality of base stations is or is not from said currently preferred base station; and periodically selecting, in response to said periodic signaling on said uplink from said UE, a power control method for at least a shared downlink to said UE from said at least one of said more than one of said plurality of base stations, wherein, if said signaling step signals that said dedicated downlink from said at least one of said one or more base stations to said UE is from said currently preferred base station, then said step of periodically selecting selects a power control method for a shared downlink to said UE based on a power level of said dedicated downlink to said UE from said currently preferred base station, and wherein the periodic signaling utilizes a site selection diversity transmission (SSDT) in the uplink.
