Abstract: Systems and methods used by reduced sensing user equipment (UE) (relative to a full sensing UE) are disclosed herein. A UE performing partial sensing may use knowledge of resource reservation periods for a resource pool of one or more resources to reduce sensing as compared to the full sensing case. A UE performing resource re-evaluation and/or resource pre-emption may use one or more sensing windows that are relatively smaller than windows used in the full sensing case to reduce sensing. A UE performing prioritized resource selection may use a sensing window to determine availability of resources within a prioritized resource selection window with a high reliability, thereby reducing the need to spend power on other sensing methods (which may include full sensing methods). Combinations of these embodiments are also contemplated.

Abstract: This disclosure relates to techniques for a wireless device to perform gradual timing adjustments in a non-terrestrial wireless communication system. According to the techniques described herein, a wireless device may establish a non-terrestrial network based wireless link with a cellular base station. The wireless device may detect a trigger for changing a gradual timing adjustment rate from a first gradual timing adjustment rate to a second gradual timing adjustment rate. The wireless device may determine a time window for which to perform gradual timing adjustment at the second gradual timing adjustment rate. The wireless device may perform gradual timing adjustment at the second gradual timing adjustment rate for the time window.

Abstract: This disclosure relates to techniques for performing beam failure recovery in a high speed single frequency network scenario in a wireless communication system. A wireless device may establish a cellular link with a cellular network according to a single frequency network scheme. The wireless device may determine one or more beam failure detection resources for each of multiple transmission reception points associated with the cellular network. The wireless device may detect beam failure for one or more of the transmission reception points using the beam failure detection resources.

Abstract: In accordance with aspects of the present disclosure, a user equipment (UE) may receive a physical sidelink shared channel (PSSCH) transmission via a slot i and a sub-channel j. The UE may determine, within a resource block (RB) set k and a physical sidelink feedback channel (PSFCH) transmission occasion n, at least one interlace to use for a PSFCH transmission based at least in part on an index of the slot i, an index of the sub-channel j, a PSFCH periodicity, and a quantity of sub-channels in the RB set k. The UE may transmit the PSFCH transmission via the at least one interlace in the RB set k during the PSFCH transmission occasion n. The PSFCH transmission may include feedback for the PSSCH transmission.

Abstract: This disclosure relates to apparatuses and methods for providing and managing reception feedback for multicast and broadcast services (MBS). A base station (BS) may select and communicate, to a group of user equipment devices (UEs), configuration parameters for MBS communications, such as an indication of an MBS retransmission procedure for an MBS service. The BS may also transmit, to the group of UEs, an MBS data communication. A first UE may receive the MBS data communication, but may determine that the received MBS data communication is corrupted. The first UE may respond by transmitting, to the BS, a negative-acknowledgement (NACK) message. The BS may retransmit the MBS data communication either as an MBS transmission or as a unicast transmission, based on the configuration parameters. The first UE may monitor the appropriate resources to receive the retransmitted MBS data communication, based on the configuration parameters.

Abstract: A user equipment (UE) configured to determine a resource selection window which identifies a first set (e.g., a total set) of candidate resources. The UE may then remove one or more candidate resources from the first set of candidate resources in response to receiving sidelink control information (SCI) from a pedestrian UE with a reservation of the one or more first candidate resources. After removal of these candidate resources from the initial or first set based on their presumed unavailability, the result may be a second set of candidate resources, which may be a subset of the initial or first set for use in communicating with a third UE. The UE may also be configured to remove candidate resources based on a reference signal receive power (RSRP) threshold which can also be adjusted based on a maximum value or a highest priority of the pedestrian UE's data.
