Abstract: Methods and systems are disclosed for a UE of a wireless communication network to recover from MCG radio link failures in a MR-DC system when the SCG is deactivated or otherwise not enabled. When a MCG link failure is detected and the SCG is deactivated, the UE may activate the SCG for the UE to use the SCG link to transmit and receive signaling messages or data as part of the MCG failure recovery procedure. When the MCG link failure is detected and the UE is configured to add the SCG upon the satisfaction of certain condition, but the condition has not occurred, the UE may check to determine whether one condition is MCG failure and whether the radio link quality of the SCG exceeds a threshold. If the radio link quality of the SCG exceeds the threshold, the UE may apply the SCG configuration to add the SCG.

Abstract: A user equipment (UE) is configured to join a standalone non-public network (SNPN). The receives SNPN information from one or more broadcast messages transmitted from a base station serving as an onboarding base station for the SNPN, determines whether the onboarding base station may be used for onboarding by the UE based on the SNPN information and UE SNPN information stored at the UE and onboards the UE to the SNPN when it is determined that the onboarding base station may be used for onboarding by the UE.

Abstract: Methods and apparatus are provided for a UE to determine a UL spatial relation for an UL transmission in response to an unknown UL spatial relation switch. The UE may determine whether the UL spatial relation is based on an SRS transmission in UL, a CSI-RS in DL, or an SSB in the DL. If the UL spatial relation is based on the SRS transmission, the UE may select the UL spatial relation for the UL transmission corresponding to a Tx beam of the SRS transmission. If the UL spatial relation is based on the CSI-RS or the SSB, the UE may select the UL spatial relation for the UL transmission based on whether the unknown UL spatial relation switch is due to a corresponding resource for beam training not being configured by a communication network or a corresponding beam information being expired.

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 transmits a connection request message to a base station over a first network using the first SIM, where the connection request message includes one or more capability indications of the UE. The UE receives a connection accept message from the base station, where the connection accept message includes one or more network capability indications corresponding to respective UE capability indications of the one or more UE capability indications. The UE performs communications with the base station according to the one or more network capability indications.

Abstract: Methods and apparatuses are disclosed for signaling unused channel occupancy time (COT) to the gNB for COT sharing among other UEs. Upon determining that a portion of the maximum COT (MCOT) provided to the UE will be unused, the UE can generate COT sharing information for transmission back to the gNB. The COT sharing information identifies a starting point and a duration (e.g., a number of consecutive slots) of the unused portion of the MCOT. This information is then encoded into configured grant uplink control information (UG-UCI) and transmitted to the gNB as part of the uplink transmission. In aspects, the unused portion may begin part-way through a slot. In this instance, a starting symbol of the unused portion or an ending symbol of the used portion may also be encoded into the uplink transmission. In this manner, unused COT is not wasted, but rather repurposed by the gNB.

Abstract: A user equipment (UE) may receive a downlink message from a non-terrestrial network (NTN) which may include one or more sets of terrestrial network (TN) cell reselection information. The one or more sets of TN cell reselection information may further include location information corresponding to one or more cells of the TN. The UE may determine its location and, in response to receiving the downlink message, compare its location to the location information corresponding to the one or more cells of the TN. The UE may then select, based on the comparison, a set of the one or more sets of TN cell reselection information and further perform a cell reselection procedure based on the selection.

Abstract: Systems and methods for small data transmissions (SDTs) between a user equipment (UE) and a network are disclosed herein. In some embodiments, the UE determines whether to perform an SDT procedure by comparing its own mobility state to an SDT mobility state condition provided by the network. The UE may also determine whether to perform the SDT procedure by comparing the size of user plane (UP) data to be sent with the SDT procedure to an SDT mobility-based data amount threshold provided by the network. Upon entering an RRC_INACTIVE state, the UE may start a validity timer relative to any such SDT mobility state condition and/or SDT mobility-based data amount threshold, and invalidate these once the validity timer expires. In some disclosed embodiments, the UE reports its determined mobility state to the network during an SDT procedure so that the network can accordingly select configuration parameters for SDT procedures.

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: 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.
