Abstract: Embodiments are presented herein of apparatuses, systems, baseband processors, and methods for performing vehicle-to-everything sidelink communication. A wireless device receives first control information through a sidelink control channel specifying one or more first time slots for the wireless device to transmit a first acknowledgment message over a sidelink feedback channel. The wireless device transmits second control information through the sidelink control channel specifying one or more second time slots for the wireless device to receive a second acknowledgment message over the sidelink feedback channel. The first and second time slots at least partially overlap, and it is determined whether the first data packet or the second data packet has a higher priority. The acknowledgment message associated with the higher priority data packet is transmitted or received during at least a subset of the overlapping time slots.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for performing vehicle-to-everything (V2X) sidelink communications with hybrid automatic repeat request (HARQ) feedback include using a new long physical sidelink feedback channel (PFSCH) format, i.e., PFSCH format 1, to assign feedback resources for various sidelink communication networks and environments where the existing or legacy sidelink feedback format, i.e., the short PFSCH format, referred to herein as PFSCH format 0, is insufficient to support effective acknowledgements (ACKs) and non-acknowledgements (NACKs) due to the limited nature of the format design.

Abstract: Apparatuses, systems, and methods for PDCCH enhancements for group-based paging indications. A user equipment device may be configured to receive, from a network, an indication of a paging occasion via a PG-RNTI and/or via at least 6 bits of a DCI. A value of the PG-RNTI may be associated with the paging occasion as well as a set of UEs, including the UE. The UE may be configured to monitor the paging occasion based on the value of the PG-RNTI and receive, during the paging occasion, a paging indication via at least six bits of a DCI, where each bit of the at least six bits may indicate a paging indication for a particular set of UEs and the particular set of UEs may be a subset of the set of UEs. The UE may also be configured to, in response to determining that the UE has a paging message, decode a corresponding PDSCH.

Abstract: A user equipment (UE) configured as a relay UE between a remote UE and a base station is disclosed. The UE comprises one or more processors configured to receive a RRC signaling to request for establishing or resuming RRC connection from the remote UE, determine whether to perform an access control check prior to forwarding the RRC Signaling of the remote UE to the base station, and forward the RRC Signaling to the base station based on the determination.

Abstract: A first user equipment (UE) is capable of serving as a relay for a second UE using a sidelink connection. The first UE determines that a predetermined condition is satisfied, the predetermined condition associated with the first UE operating as a relay for a second UE, transmits a discovery message and monitors for a signal from the second UE in response to the discovery message.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing downlink transmission and interlace uplink transmission. For example, some aspects of this disclosure relate to a base station including a transceiver configured to communicate over a wireless network with a user equipment (UE) and a processor communicatively coupled to the transceiver. The processor divides a plurality of candidate Synchronization Signal Block (SSB) positions in a time window into a plurality of groups and communicates, using the transceiver, information associated with the plurality of groups of candidate SSB positions to the UE. The processor further performs a listen-before-talk (LBT) procedure. In response to the LBT procedure being successful, the processor determines a first group of the plurality of groups and transmits, using the transceiver, one or more SSBs on one or more candidate SSB positions of the first group to the UE.

Abstract: Systems and methods for sidelink (SL) power control within wireless communication systems are disclosed herein. A user equipment (UE) selects a parameter set to use to calculate a transmit power of one or more channels to be transmitted according to an SL session with a peer UE from a plurality of parameter sets each configured for use according to a distance between the UE and the peer UE. A UE determines whether an SL pathloss based calculation is to be used to calculate a transmit power of a channel according to an SL session with a peer UE, wherein that calculation is configured to be used depending on a distance between the UE and the peer UE. UE selection of a number of physical SL feedback channel (PSFCH) transmissions to match a UE capability and determinations regarding whether to perform PSFCH reception or PSFCH transmission are also discussed.
