    Abstract: A repeater configured to receive, on a side control channel from a component of a network, side control information including parameters at least for determining time domain resources on which to apply an indicated beam for uplink (UL) transmission reception or downlink (DL) transmission forwarding with a user equipment (UE) on an access link, determine, from the received parameters, whether to apply the indicated beam to a transmission (Tx) spatial filter, a reception (Rx) spatial filter, or both the Tx and Rx spatial filters and apply the indicated beam to the determined Tx spatial filter, Rx spatial filter, or both the Tx and Rx spatial filters for the determined time domain resources when forwarding the DL transmission to the UE or receiving the UL transmission from the UE for forwarding to the network.

    Abstract: Apparatuses, systems, and methods for SRS antenna switching. A UE may transmit, to a base station, a capability message indicating an antenna configuration associated with SRS antenna switching e.g., via as RRC signaling. The capability message may indicate at least one of (and/or one or more of) a one transmit point (1T) and six receive point (6R) SRS resource set configuration, a 1T8R SRS resource set configuration, a 2T6R SRS resource set configuration, a 2T8R SRS resource set configuration, and/or a 4T8R SRS resource set configuration. The UE may receive, from the base station, a configuration message, e.g., via RRC signaling. The configuration message may indicate an SRS antenna switching configuration based, at least in part, on the capability message. The UE may transmit, to the base station, one or more SRSs, e.g., according to the SRS antenna switching configuration.

    Abstract: Systems and methods are configured for receiving configuration data specifying a mapping for physical sidelink shared channel (PSSCH) or physical sidelink control channel (PSCCH) resource blocks to respective candidate physical sidelink feedback channel (PSFCH) resource blocks, the mapping specifying, for a PSSCH or PSCCH transmission, a set of candidate PSFCH resource blocks, the set of candidate PSFCH resource blocks including a common interlace resource block and a set of dedicated resource blocks for PSFCH transmissions; transmitting the PSSCH or PSCCH transmission; and receiving, based on the mapping, a PSFCH transmission from a user equipment (UE), the PSFCH transmission being transmitted using a PSFCH resource block of the set of candidate PSFCH resource blocks.

    Abstract: Systems, methods, and circuitries are provided for configuring HARQ feedback for semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) communication. In one example, a method includes identifying a physical uplink control channel (PUCCH) resource in a first slot for communicating a hybrid automatic repeat request (HARQ) codebook. The method includes determining a set of SPS PDSCH receptions for which feedback is multiplexed in the HARQ codebook based on SPS PDSCH configurations for each component carrier and each slot, a UE capability for number of SPS PDSCH receptions per slot, and a prioritization protocol. The method includes selecting a codebook type based on whether a PDSCH is scheduled by way of a dynamic grant for any of the plurality of slots, constructing the HARQ codebook based on the set of SPS PDSCH receptions and the selected codebook type, and transmitting the HARQ codebook to a next generation node.

    Abstract: This disclosure relates to techniques for time division multiplexing sounding reference signal ports in a wireless communication system. A wireless device and a cellular base station may establish a wireless link. The wireless device may be configured to perform a sounding reference signal transmission with time division multiplexing sounding reference signal ports. A maximum transmit power for the wireless device for the sounding reference signal transmission may be determined based at least in part on the time division multiplexing sounding reference signal ports. A transmit power may be selected for the sounding reference signal transmission based at least in part on the maximum transmit power for the wireless device for the sounding reference signal transmission. The sounding reference signal transmission may be performed using the selected transmit power.

    Abstract: A method for performing a contention-free random access (CFRA) in a lower-layer triggered mobility (LTM) procedure from a serving cell to a target candidate cell is provided. The method includes determining, by a user equipment (UE), that random access response (RAR) reception is not configured for the UE. The method includes receiving, by the UE, a physical downlink control channel (PDCCH) order for transmitting a physical random access channel (PRACH) signal to the target candidate cell. The method includes determining, by the UE and based on the PDCCH order, a transmission power for transmitting the PRACH signal.
