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.

Abstract: A user equipment (UE), a base station (e.g., next generation NodeB (gNB)), or other network component can operate to configure a beam failure recovery (BFR) timing based on a time offset and a number of symbols in a BFR procedure, as well as enable beam switching and bandwidth part (BWP) switching to be correlated. A beam failure recovery request (BFRQ) can be processed or transmitted in response to a detection of a beam failure. A beam failure recovery response (BFRR) can be generated via a physical downlink control channel (PDCCH) based on at least four slots after the BFRQ and a time offset for a non-terrestrial network (NTN).

Abstract: Systems, methods, and circuitries are provided for supporting blind retransmission. In one example, a method includes determining one or more communication parameters for use in communicating with a user equipment (UE) based on whether hybrid automatic repeat request (HARQ) feedback is enabled for the UE; and using at least one of the one or more communication parameters when HARQ feedback is determined to be enabled.

Abstract: A user equipment (UE) may monitor a downlink frequency position to detect a synchronization block (SSB) from a cellular base station. When monitoring the downlink frequency position, the UE may be configured to use at least one step size in calculating a SSB frequency position. The UE may determine a subcarrier spacing (SCS) used by the cellular base station in response to monitoring the downlink frequency position, and the subcarrier spacing for one or more SSB transmissions may be determined at least in part based on the step size used in calculating the SSB frequency position. The UE may then utilize the determined subcarrier spacing of the one or more SSB transmissions in communicating with the cellular base station.

Abstract: A device may wirelessly communicate with a number of different cells used in a carrier aggregation. The device may monitor physical downlink control channels (PDCCHs) on the different cells, dynamically switching between a dormant monitoring state (DS) and an active monitoring state (AS). In the DS, the UE may not monitor any PDCCH candidates on the active secondary SCells corresponding to the DS, or it may monitor PDCCH candidates in the search space (SS) set with the largest monitoring periodicity among the multiple SS sets on the active bandwidth part (BWP). In the AS, the UE may monitor a set of PDCCH candidates in physical resources configured by higher layers on the BWPs. Switching from one monitoring state to another may be facilitated through the use of a new downlink control information (DCI) format without data scheduling, a modified existing DCI format with data scheduling, and/or use of a DS timer.
