Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an adjusted contention window size for a listen-before-talk (LBT) procedure that increases channel access time fairness between a plurality of different groups of UEs. The UE may determine, via the LBT procedure, that a channel is idle based at least in part on the adjusted contention window size. The UE may transmit, to other UEs in a group of UEs that includes the UE, control information that enables a group channel occupancy time (COT) associated with the channel to be shared with the other UEs in the group of UEs. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatuses for using a media access control (MAC) control element (CE) for dynamic RLC entities selection. In one aspect, a base station (BS) may generate and transmit the control message to a user equipment (UE) to identify active radio link control (RLC) entities, a primary RLC entity, or other parameters relating to packet data convergence protocol (PDCP) duplication-based communication. In this case, the UE may use the control message to select an RLC entity and may transmit protocol data units (PDUs) to the BS using a data radio bearer (DRB) and the selected RLC entity.

Abstract: Aspects relate to wireless communication where a master node (MN) or a secondary node (SN) may initiate a conditional addition of a primary secondary cell (PSCell) or a conditional change from one PSCell to another PSCell. Each candidate target PSCell may provide information to be used by the MN to generate a conditional PSCell addition (CPA) configuration or a conditional PSCell change (CPC) configuration that is sent to a user equipment (UE). This information may indicate an execution condition for each candidate target PSCell and/or radio bearers that each candidate target PSCell supports or does not support. An MN may modify a master cell group (MCG) configuration for a PSCell based on information received from a target SN with an secondary cell group (SCG) configuration for the PSCell. The MN may transmit a CPA or CPC configuration including the modified MCG configuration and the SCG configuration to the UE.

Abstract: A configuration for dynamic capacity for multiple universal subscriber identity modules. The apparatus transmits, to a base station, UE capability information in response to a UE capability enquiry, the UE capability information including a set of UE capabilities. The apparatus transmits, to the base station, UAI including an IE indicating a modified subset of UE capabilities of the set of UE capabilities when multiple USIMs are active at the UE. The apparatus operates based on the modified subset of UE capabilities when multiple USIMs are active at the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication that a secondary cell group (SCG) is to enter an SCG dormant state and an indication for using one or more of configured grant (CG) on an uplink or semi-persistent scheduling (SPS) on a downlink for communication with a secondary node (SN) of the SCG during the SCG dormant state. The UE may communicate with the SN of the SCG during the SCG dormant state using the one or more of CG or SPS. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to power saving over a forward link of a star topology of user equipment (UE) are provided. In some aspects, a first UE may monitor the forward link connecting a second UE to the first UE for a control message transmitted by the second UE to the first UE. The first UE may then establish an operational mode based on the result of the monitoring for the control message, such as but not limited to a power saving mode or an active mode.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of cell quality measurements for a set of candidate target cells. The UE may select a target cell, from the set of candidate target cells, and a beam, of one or more beams of the target cell, for a conditional handover procedure and based at least in part on the set of cell quality measurements. The UE may perform the conditional handover procedure to transfer from a source cell to the target cell based at least in part on selecting the target cell and the beam. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may operate, in connection with a secondary cell group (SCG) for multiple radio access technology dual connectivity, in one of an SCG dormant state in a dormant downlink bandwidth part (BWP) configured for a primary secondary cell of the SCG or an SCG enhanced dormant state in an enhanced dormant downlink BWP configured for the primary secondary cell. The UE may receive a control message associated with activating the SCG for the UE, the control message indicating a BWP switch for the UE. The UE may switch, in connection with receiving the control message, from one of the dormant downlink BWP or the enhanced dormant downlink BWP to an activated downlink BWP in which the UE operates in an SCG activated state. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect radio link failure on a master cell group. Accordingly, the UE may determine a state of a secondary cell group (SCG). Additionally, the UE may initiate activation of the SCG based at least in part on the state of the SCG. For example, the activation of the SCG may be initiated based at least in part on the state being a deactivated state, a dormant state, or an enhanced dormant state. Accordingly, the UE may transmit master cell group (MCG) failure recovery information over the SCG and receive, on the SCG, MCG reconnection information. Numerous other aspects are provided.
