COHERENT AND NON-COHERENT CONTROL SIGNALING

摘要

A method is provided where unused uplink code resources of a shared control resource are used for non-coherent acknowledgement/negative acknowledgement transmission to increase the total number of user equipment that can be supported. The method including defining a shared uplink control resource to include JV out of a possible M uplink control resources as being coherent uplink control resources, where M > N, defining at least one of the remaining M- N uplink control resources as non-coherent uplink control resources, and assigning the N coherent uplink control channel resources and the at least one M-N non-coherent uplink control resources to user equipment as needed.
