Abstract: A user equipment (UE) is configured to receive, from a base station of a wireless network, a deactivation indication indicating that a secondary cell group (SCG) of a dual connectivity (DC) wireless communications configuration has been deactivated, receive, from the base station, a remapping indication indicating that SCG data originally mapped to an SCG bearer should be remapped to an alternate bearer, remap the SCG data to the alternate bearer based on the remapping indication and transmit data over the alternate bearer.

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: A user equipment (UE) may be configured with information to perform conditional handovers or addition/change of a primary secondary cell (PSCell). The UE receives a first radio resource control (RRC) configuration message from the source cell for conditional handover to the at least one target cell, the first RRC configuration message including conditional handover execution conditions, an RRC configuration and a target cell ID for each one of a list of target cells, performs measurements on the target cells to determine whether any one of the target cells fulfills its corresponding conditional handover execution conditions and, when a first target cell from the list of target cells fulfills its corresponding conditional handover execution conditions, initiates a handover to the first target cell.

Abstract: Techniques for flexible hybrid automatic repeat request selection by a user equipment are provided. An example method includes a user equipment (UE) processing a plurality of physical uplink shared channel (PUSCH) opportunities associated with a configured grant (CG) cycle. The UE can apply a first logical channel prioritization (LCP) setting when processing a first PUSCH opportunity of the plurality of PUSCH opportunities. The UE can evaluate whether a condition for switching from the first LCP to a second LCP of the plurality of PUSCH opportunities has been met. The UE can, based on the evaluation, apply a second LCP setting when processing the second PUSCH opportunity.

Abstract: Techniques are described for improving service continuity for Multicast and Broadcast Services (MBS) communications during handover. Techniques are included for supporting lossless handover and data forwarding during handover for peer-to-multiple (PTM) MBS transmission. Lossless handover may be achieved in part by the user equipment (UE) providing to the target base station an indication of the next packet of the MBS session to be received following an RRC reconfiguration message, and an indication of any MBS packets provided by the source base station prior to the RRC reconfiguration message that were not properly received by the UE. Data forwarding may be performed from the source base station to the target base station if the MBS session was not configured on the target base station prior to the handover. Data forwarding may be omitted if the MBS session was configured on the target base station prior to the handover.

Abstract: A user equipment (UE) may camp on a base station of a network. The UE receives, from the base station of a wireless network, a broadcast including access restrictions, wherein the access restrictions include one or more predetermined criteria that must be satisfied to camp on the base station. The UE then determines whether the UE satisfies the one or more predetermined criteria.

Abstract: A technique for determining that a wireless device supports using multiple subscriber identity module (SIM) cards to establish multiple connections to wireless networks, generating a multi-SIM capability message, and transmitting the multi-SIM capability message to a first wireless network. In another aspect, a technique for a wireless system to receive a multi-SIM capability message from a wireless device, determine a connection configuration of the wireless device based on the received multi-SIM capability message, and transmit an indication of the configured connection to the wireless device.

Abstract: To accommodate a mix of high frequency carriers and lower frequency carriers, a protocol stack may include a radio link control (RLC) entity that allows configuration of status reporting control parameters on per carrier, or per subcarrier spacing. Alternatively, a protocol stack may include two RLC entities, one for handling high frequency carriers, and another for handling lower frequency carriers. (High frequency carriers and lower frequency carriers may be distinguished based on a frequency threshold.) Furthermore, a user equipment may transmit (to the network) an indication of its L2 buffer size. The network may configure the UE and/or control scheduling, to ensure the UE's L2 buffer does not overrun. Alternatively, the UE may indicate that it can support a percentage of a maximum buffer size. The network may configure the UE and/or control scheduling so that the UE's buffer occupancy does not exceed the percentage.

Abstract: This disclosure relates to techniques for quickly recovering from radio link failure in a wireless communication system. A wireless device may establish a wireless link with a cell. The wireless device may detect radio link failure for the wireless link. The wireless device may attempt to re-establish the wireless link using a previously provided wireless link configuration. If the cell accepts the attempt re-establish the wireless link using the previously provided wireless link configuration, the wireless link may be re-established in accordance with the previously provided wireless link configuration.
