Abstract:
1. A method for assigning uplink acknowledgement (ACK) resources for a user equipment (UE) in a wireless communication system, comprising: identifying a UE for which a persistent assignment of communication resources for a plurality of data transmissions is to be established; identifying uplink ACK resources of a shared uplink control channel for use by the identified UE; communicating an explicit assignment of the identified uplink ACK resources via Layer 3 (L3) signaling, or a downlink control channel, or both L3 signaling and the downlink control channel to the identified UE for the persistent assignment of communication resources to the UE, without sending an assignment of uplink ACK resources for each of the plurality of data transmissions pursuant to the persistent assignment, wherein the communicating comprises communicating an uplink ACK index corresponding to the identified uplink ACK resources on the downlink control channel via Layer 2 (L2) signaling; and receiving ACK feedback sent on the uplink ACK resources by the identified UE.
