  • Publication number: 20240098639
    Abstract: Systems and methods related to “on/off” determinations regarding the performance of physical downlink control channel (PDCCH) monitoring during connected mode discontinuous reception (CDRX) on duration windows are disclosed herein. In some cases, a radio access network (RAN) predicts whether a downlink (DL) packet for a UE will arrive at a buffer of the RAN prior to an end of a CDRX on duration window of the UE, and sends a downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a power-saving radio network temporary identifier (PS-RNTI) (DCP) for the CDRX on duration window indicating whether or not the UE should perform PDCCH monitoring during the CDRX on duration window based on the prediction. In some cases, a UE determines a current state of DL traffic and adaptively uses DCP monitoring based on the current state of the traffic. Aggregation level adaptation by the RAN is also discussed.

  • Publication number: 20240032002
    Abstract: Provided is a method for a user equipment (UE). The UE obtains a slot allocation information from a network device. The slot allocation information indicates a first slot and a second slot. The first slot is configured to communicate voice traffic and the second slot is configured to communicate traffic other than voice. The UE communicates the voice traffic in the first slot and the traffic other than voice in the second slot.
