Using channel configuration information from multiple cells in multipoint communications between the cells and a UE

A user equipment UE obtains common channel configurations from each of a serving cell and n neighbor cells (204-1 to 204-3), from which the UE creates a combined channel configuration 208 and utilizes it for multipoint communications with those cells. The respective channel configurations may be obt...

More Information
Summary:A user equipment UE obtains common channel configurations from each of a serving cell and n neighbor cells (204-1 to 204-3), from which the UE creates a combined channel configuration 208 and utilizes it for multipoint communications with those cells. The respective channel configurations may be obtained from the respective cells' system information broadcasts. The n neighbor cells are cells which have been determined to be suitable for joint data communication with the UE. The determination may involve the UE receiving a neighbor cell list (NCL) and threshold 202 and, for each cell in the NCL, comparing received signal strength or another quality metric with the threshold 206. The UE may then report, in uplink signaling 210, the n neighbor cells which are suitable for multipoint communication with the UE. The invention may be used to provide multipoint reception, at a UE in the CELL-FACH state, from multiple network cells.
