  • Publication number: 20210281368
    Abstract: A user equipment (UE) may assess a radio link quality of a plurality of frames for communication, via the interface to the RF circuitry, with a radio access network (RAN) node. When the radio link quality of a frame, of the plurality of frames, is below an out-of-sync (OOS) threshold, the UE may indicate that the frame is OOS. When the radio link quality of a frame, of the plurality of frames, is above an in-sync (IS) threshold that the frame is IS. Additionally, or alternatively, the UE may process information, received from the RAN node indicating a partial subframe, of a subframe, to be used to transmit uplink control information (UCI) to the RAN node. The UE may also perform UCI mapping for using of the partial subframe to transmit UCI via a physical uplink control channel (PUSCH), and proceed by using the partial subframe to communicate the UCI to the RAN node.
