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 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 SPS 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.

1. A method, comprising:
determining a set of semi-persistent scheduling acknowledge/negative acknowledge resources; configuring as a first metric for each member of the set of semi-persistent scheduling acknowledge/negative acknowledge resources a count of a number of user equipments for which the semi-persistent scheduling acknowledge/negative acknowledge resource has been configured but for which semi-persistent scheduling is not activated; configuring as a second metric for each member of the set of semi-persistent scheduling acknowledge/negative acknowledge resources a count of a number of sub-frames in which the semi-persistent scheduling acknowledge/negative acknowledge resource has been activated for a user equipment; configuring as a third metric for each member of the set of semi-persistent scheduling acknowledge/negative acknowledge resources a count of a number of user equipments for which the particular semi-persistent scheduling acknowledge/negative acknowledge resource is configured but some other semi-persistent scheduling acknowledge/negative acknowledge resource is allocated during semi-persistent scheduling activation; forming a fourth metric for each member of the set of semi-persistent scheduling acknowledge/negative acknowledge resources as a combination of the first metric, the second metric and the third metric; selecting N semi-persistent scheduling acknowledge/negative acknowledge resources from the set of semi-persistent scheduling acknowledge/negative acknowledge resources to potentially configure for a new semi-persistent-scheduling configured user equipment based at least on the value of the fourth metric; and selecting one of the N semi-persistent scheduling acknowledge/negative acknowledge resources of the N semi-persistent scheduling acknowledge/negative acknowledge resources based at least on the value of the fourth metric when the user equipment is activated for semi-persistent scheduling operation.
