Uplink Control Channel Resource Allocation For Semi-Persistent Scheduling Of User Equipment

摘要

A method includes determining semi-persistent scheduling acknowledge/negative acknowledge (SPS AN) resources; configuring as a first metric for each SPS AN resource a number of user equipments (UEs) for which the SPS AN resource has been configured but is not activated; configuring as a second metric for each SPS AN resource a count of a number of sub-frames in which the SPS AN resource has been activated for a UE; configuring as a third metric for each SPS AN resource a number of UEs for which the resource is configured but some other SPS AN resource is allocated; forming a fourth metric using the first, second and third metrics; selecting N SPS AN resources from the PS AN resources based at least on the fourth metric; and selecting one of the N SPS AN resources based at least on the fourth metric when the UE is activated for SPS operation.
