  • Publication number: 20250151069
    Abstract: Various aspects of the present disclosure relate to a user equipment (UE) that maintains a set of skipping durations that includes multiple subsets of skipping durations. The base station transmits to the UE a first control signaling indicating to activate one of the subsets of skipping durations. At a subsequent time, the base station transmits to the UE a second control signaling indicating that the UE can skip physical downlink control channel (PDCCH) monitoring in some time resources (e.g., slots). The second control signaling includes an identifier of a skipping duration and the UE selects the identified skipping duration in the active subset of skipping duration values. The UE then skips or terminates monitoring of the PDCCH for the selected skipping duration.

  • Publication number: 20250106169
    Abstract: Various aspects of the present disclosure relate to a user equipment (UE) that receives scheduling information for a set of physical downlink shared channel (PDSCH) transmissions. The UE also receives downlink control information (DCI) comprising an indication to discard processing of a subset of PDSCH transmissions of the set of PDSCH transmissions, the DCI received prior to a first PDSCH transmission of the subset of the PDSCH transmissions. The UE can discard processing of the subset of the PDSCH transmissions based at least in part on the received DCI indication. For example, to discard the processing of the subset of the PDSCH transmissions, the UE can terminate hybrid automatic repeat request acknowledgement (HARQ-ACK) operations, or skip forward error correction operations associated with the subset of the PDSCH transmissions, or both.
