  • Patent number: 11419052
    Abstract: A user equipment (UE) interacts with a base station (BS) to activate a power saving mode based on a triggering condition. The UE receives reference signals (RSs) from a first RS-set of quasi-colocated (QCLd) RSs, derives a measurement result by measuring the RSs, and uses the first measurement result (and in some cases measurements results for other RS set) for evaluation of the triggering condition to identify whether the triggering condition is satisfied. The UE and the BS switch from the first RS-set to a second RS-set once the triggering condition is satisfied.

  • Patent number: 11394497
    Abstract: A user equipment (UE) receives physical downlink shared channel (PDSCH) in a downlink slot as scheduled using a downlink control indicator (DCI). The UE identifies that the downlink slot is part of a group of downlink slots based on the DCI and/or another DCI corresponding to the group. The UE identifies one or more uplink slots at which to transmit hybrid automatic repeat request (HARQ) feedback corresponding to the slots in the group, and transmits the HARQ feedback at one of these uplink slots. If HARQ feedback is not received, a semi-static codebook may prevent HARQ payload size misalignment.
