RESOURCE ALLOCATION INDICATION FOR PHYSICAL UPLINK CONTROL CHANNEL (PUCCH)

Techniques for communication of resource allocation indication for a shortened physical uplink control channel (sPUCCH) or an enhanced physical uplink control channel (ePUCCH) in MulteFire systems. A network device (e.g., an evolved NodeB, user equipment, or other network device) can enable sPUCCH and ePUCCH carrying HARQ-ACK feedback. Resource allocations for sPUCCH and ePUCCH can be configured by one or more of: a higher layer signaling, an acknowledgement resource indicator (ARI), a control channel element (CCE) index, or a combination thereof. Various triggering operations for the sPUCCH and the ePUCCH are also considered.
