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 performing beam failure recovery during an inter-cell connection involving a UE in communication with one or more base stations in a cellular communication system. In various embodiments, a user equipment determines one or more beam failures by monitoring one or more reference signals transmitted by one or more base stations, where the UE is connected to the one or more base stations. The UE further performs candidate beam detection by monitoring at least one candidate reference signal that is transmitted by one or more candidate base stations, where at least one candidate base station (a first candidate base station) is different from the one or more base stations to which the UE was previously communicating. The UE selects the first candidate base station based on the candidate beam detection, and transmits a beam failure recovery request (BFRQ) message to the first candidate base station based on the selection.

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: This disclosure relates to techniques for performing multi-transmission and reception point operation in a wireless communication system. A plurality of transmission control indication states may be indicated for future use, e.g., using one or more separately identified lists. A subset of the indicated states may be activated. One or more states of the subset may be used for performing multi-transmission and reception point operation in a single downlink control information mode.

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.

Abstract: Disclosed are techniques for reducing likelihood of Random Access Channel (RACH) transmission blockages and thereby facilitate an initial access procedure for new radio (NR) unlicensed spectrum (NR-U) operation in a fifth generation (5G) wireless communication system including an NR node. In some embodiments, a parameter generated by a gNB and received by a UE indicates that, from among a set of consecutive RACH Occasions (ROs), a gap is available for performing a listen-before-talk (LBT) procedure before commencing a RACH transmission.

Abstract: A user equipment (UE) performs uplink (UL) transmissions to a network. The UE receives a frequency domain resource allocation (FDRA) configuration from a network, the FDRA configuration comprising at least one of a first FDRA mode or a second FDRA mode, wherein the first FDRA mode utilizes an FDRA unit comprising a set of consecutive resource blocks (RBs) and the second FDRA mode utilizes an FDRA unit comprising a set of interlaced RBs, when both of the first and second FDRA modes are configured, the UE receives a signal indicating which one of the two FDRA modes are to be used for an uplink (UL) transmission and performs the UL transmission in accordance with the indicated FDRA mode.
