Abstract: A method for releasing a semi-persistently scheduled (SPS) physical downlink shared channel (PDSCH) includes: receiving, by a PDSCH manager of a user equipment, a SPS release physical downlink control channel (PDCCH) in a scheduling cell, the SPS release PDCCH identifying N SPS PDSCH configuration indices to be released; identifying a slot of a scheduled cell, where the slot of the scheduled cell overlaps with the end of an ending symbol of the SPS release PDCCH; identifying M SPS PDSCH configuration indices including all configuration indices from among the N SPS PDSCH configuration indices that are scheduled in the slot; and releasing L SPS PDSCH configuration indices among the M SPS PDSCH configuration indices based on determining that the ending symbol of the SPS release PDCCH is before a corresponding ending symbol associated with each of the L SPS PDSCH configuration indices of the slot.

Abstract: Method of resource selection where a selection window with a total number of resources is set. The method includes setting a sensing window and monitoring slots by decoding a physical sidelink control channel (PSCCH) and measuring a reference signal received power (RSRP), setting a threshold, excluding any restricted resources from the total number of resources, excluding any occupied resources from the total number of resources, and determining if an initial number of remaining resources is greater than or equal to an initial percentage of the total number of resources.

Abstract: A method may include generating a receive timing error group (Rx TEG) based on a time delay of a receive (Rx) signal, wherein the time delay is a time measured from an arrival of the Rx signal at a Rx antenna to a time of the Rx signal being digitized and time-stamped at a baseband processor of a user equipment (UE), determining a timing error group (TEG) index corresponding to the generated Rx TEG, determining a positioning measurement associated with the Rx antenna used to generate the Rx TEG, and reporting the positioning measurement associated with the Rx TEG index.

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.

Abstract: Methods and apparatuses for managing dual connectivity. A method for operating a UE includes receiving a configuration for dynamic power sharing (DPS) between transmissions on a master cell group (MCG) and transmissions on a secondary cell group (SCG) and determining a time offset as a function of sub-carrier spacing (SCS) configurations and of configurations for a PUSCH processing capability on the MCG and on the SCG. The method further includes determining a maximum power for a PUSCH transmission on the SCG, at a beginning of the PUSCH transmission on the SCG, when each of the transmissions on the MCG is scheduled by a downlink control information (DCI) format in a PDCCH reception that ends at least the time offset before the beginning of the PUSCH transmission on the SCG. The method further includes transmitting the transmissions on the MCG and the PUSCH transmission on the SCG.
