Abstract

Technology for a user equipment (UE) operable for transmission of a shortened physical uplink control channel (sPUCCH) is disclosed. The UE can map symbols to physical resource blocks (PRBs) for a first subslot and a last subslot of a subframe for the sPUCCH. The UE can encode control information for transmission to a next generation node B (gNB) in selected PRBs.
