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.

Abstract: Aspects described herein relate to receiving, by a mobile termination (MT) function of an integrated access and backhaul (IAB) node, a first indication to migrate from a first IAB donor node associated with a first cell group and a first central unit (CU) to a second IAB donor node associated with a second cell group and a second CU, performing, by the IAB node and based at least in part on receiving the first indication, a first random access procedure to connect to the second cell group associated with the second IAB donor node, establishing, by the IAB node in addition to a first distributed unit (DU) function of the IAB node that serves a third cell group and based on performing the first random access procedure, a second DU function that serves a fourth cell group.

Abstract: The present disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for layer 2 relay user equipment (UE) mobility. A relay UE relays data between a first network entity and a remote UE based on a first configuration of the remote UE. The relay UE may receive, from the first network entity on a first connection, a handover request that includes a second configuration for a second network entity or a third configuration for the remote UE. The relay UE determines whether dual active protocol stack radio link control channels are configured for the remote UE based on the first configuration or the third configuration. The relay UE establishes a second connection with the second network entity based on the second configuration, and transmits, to the remote UE, a handover status indicating a result of establishing the second connection with the second network entity.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mobility techniques that allow for mobility of a user equipment (UE) between a set of cells. A method that may be performed by a UE includes receiving signaling configuring the UE with a set of cells that support physical (PHY) layer or medium access control (MAC) layer mobility signaling and with a measurement configuration for the set of cells, reporting, to a network entity, measurements for at least some of the set of cells in accordance with the measurement configuration, and receiving, from the network entity, PHY layer or MAC layer mobility signaling to move the UE to one of the cells in the set, wherein the mobility signaling is based, at least in part, on the reported measurements.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mobility techniques that allow for dynamically updating a set of cells activated to serve a user equipment (UE) and the cell in the set of cells designated as the primary cell (PCell). An example method includes receiving signaling indicating a set of cells supported by one or more distributed units (DUs) under a common central unit (CU); identifying a subset of the set of cells activated to serve the UE, wherein a first cell of the activated cells comprises a primary cell selected from cells included in a candidate set of primary cells (PCells); and identifying another one of the activated cells to serve as the PCell if the first cell is re-designated as a secondary cell (SCell), wherein the other one of the activated cells comprises a cell selected from the candidate set of PCells.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a master node (MN) may receive a message indicating that a user equipment (UE) has determined that a condition for a conditional primary secondary cell (PSCell) change has been satisfied for a candidate target PSCell. The candidate target PSCell may be one of a set of candidate target PSCells associated with the UE in a conditional PSCell change configuration provided by a base station. The MN may transmit, to a source secondary node, a confirmation message associated with the conditional PSCell change. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive discontinuous reception (DRX) configuration information identifying a slot or sub-slot granularity for transitioning from a non-monitoring state to a monitoring state, wherein the information identifies, for each slot or sub-slot, whether to operate in the non-monitoring state or the monitoring state; and transition from the non-monitoring state, wherein the user equipment (UE) is not performing monitoring, to the monitoring state, wherein the UE is performing monitoring, in accordance with the DRX configuration information. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for multi-universal subscriber identification module (USIM) and dual connectivity operation. A method that may be performed by a user equipment (UE) includes establishing a first access link, associated with a first subscriber identification module (SIM) of the UE, for communicating with a first base station; establishing a second access link, associated with the first SIM of the UE, for communicating with a second base station; establishing a third access link associated with a second SIM of the UE; identifying at least one time division multiplexing (TDM) pattern indicating a set of time periods during which to use the third access link; and tuning to the third access link for communicating using the second SIM during at least one time period of the set of time periods indicated in the TDM pattern.
