Abstract: A method and a user equipment (UE) are provided for monitoring physical downlink control channel (PDCCH) candidates by a UE. A reference control resource set (CORESET) having a plurality of transmission configuration indicator (TCI) states is identified. The PDCCH candidates in the reference CORESET and in one or more CORESETs that overlap the reference CORESET in a time domain, are monitored. Each of the one or more CORESETs has a set of one or more TCI states that is either identical to, or a subset of, the plurality of TCI states of the reference CORESET. The monitored PDCCH candidates are received in accordance with a single frequency network (SFN) transmission scheme.

Abstract: A method for cross carrier scheduling can include: determining that a candidate DCI for a UE schedules a DG PDSCH that at least partially overlaps an SPS PDSCH for the UE, wherein the DCI is configured to be transmitted on a first CC having a first SCS, and the DG PDSCH is configured for transmission on a second CC having a second SCS different from the first SCS; determining a timing gap based on the smallest of the first SCS and the second SCS; determining that an available time between the scheduled SPS PDSCH and the DCI is equal to or greater than the timing gap; cancelling the SPS PDSCH responsive to determining that the available time between the scheduled SPS PDSCH and the DCI is equal to or greater than the timing gap; and transmitting the DCI to the UE.

Abstract: Methods and apparatuses are provided for receiving, from a user equipment (UE) configured to process a first priority channel using a first monitoring span based on the first priority channel during one or more time periods, at least one parameter indicating a minimum amount of time required by the UE to process the first priority channel using a second monitoring span based on the first priority channel and a second priority channel. The one or more time periods are based on minimum processing capabilities of the UE. Based on the at least one parameter, the UE is caused to be reconfigured with at least one time offset to increase at least one time period of the one or more time periods for processing the first priority channel.

Abstract: A method of implementing beam failure recovery for a multi-transmission-and-reception-point (M-TRP) transmission including a first transmission from a first TRP and a second transmission from a second TRP may include: receiving a first set of reference signals (RSs) corresponding to the first TRP and a second set of RSs corresponding to the second TRP; determining that the first set of RSs indicates a beam failure instance (BFI) specific to the first TRP, and responsively updating a first BFI counter specific to the first TRP; determining that a beam failure with respect to the first TRP has occurred based on a count of the first BFI counter equaling or surpassing a first BFI counter threshold; and performing a BFR process for the first TRP responsive to determining that the beam failure with respect to the first TRP has occurred.
