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.

Abstract: Devices and associated methods for operating a dual-subscriber identity module (SIM) dual-standby (DSDS) user equipment device (UE) configured with a first SIM and a second SIM. The UE performs communications with a first cellular network using the first SIM and a first radio resource control (RRC) connection, and receives a request to perform a higher priority communication using the second SIM. In response to the request to perform the higher priority communication, the UE transmits a request to the first network to suspend the first RRC connection. After transmission of the request to suspend the first RRC connection, the UE receives a message from the first network to place the first RRC connection in an inactive state, and initiates a timer, wherein the timer is used to determine whether the first RRC connection remains in the inactive state or transitions to an idle state.

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 supporting switching between point to point and point to multipoint delivery with service continuity for broadcast and multicast services in a wireless communication system. A cellular base station and a wireless device may establish a wireless link. The cellular base station may provide information configuring an over the air delivery type with which to receive a broadcast or multicast service, which may be received by the wireless device. The cellular base station may transmit the service using the configured delivery type, and the wireless device may correspondingly receive the service. The cellular base station may provide information configuring the wireless device to switch to a different over the air delivery type, with service continuity. The cellular base station may then transmit the service using that delivery type, and the wireless device may correspondingly receive the service.

Abstract: A method and apparatus of a device that determines a physical downlink shared channel scheduling resource for a user equipment device and a base station is described. In an exemplary embodiment, the device selects a plurality of component carriers from a pool of available component carriers associated with a wireless link established between the user equipment device and the base station. In addition, the device selects a virtual component carrier from the plurality of component carriers. Furthermore, the device determines a physical downlink shared channel scheduling resource based on at least the virtual component carrier.

Abstract: A user equipment (UE) performs capability exchange for indicating support of cross physical uplink control channel (PUCCH) group channel state information (CSI) reporting. In some embodiments, the UE receives a request from a network for the UE capability exchange and reports to the network whether cross PUCCH group CSI reporting is supported. The UE may also indicate whether a processing timeline for CSI reporting is to be relaxed to accommodate the cross PUCCH group CSI measurement and reporting.
