Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to switch from a first cell of a first distributed unit (DU) to a second cell of a second DU, wherein the first DU and the second DU are included in a set of DUs of a central unit (CU). The UE may communicate, using layer 1 (L1) or layer 2 (L2) signaling to change an activation status of at least one cell of the first DU or the second DU. The UE may switch from the first cell to the second cell in connection with the change to the activation status of the at least one cell of the first DU or the second DU. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for signaling a user equipment (UE) to put a sidelink (SL) component carrier (CC) into dormancy or take the SL CC out of dormancy, such as mode 1 or mode 2 sidelink communications. In one example, a method performed by a UE includes receiving an indication to put a first CC into dormancy; and putting an SL CC into a dormant state in response to the indication. In another example, a method includes transmitting an indication that the first UE will put an SL CC into a dormant state; and receiving an acknowledgment (ACK) of the indication.

Abstract: A plurality of scheduled entities, such as transmission reception points (TRPs), may each transmit at least one TRP-specific beam failure detection reference signal (BFD-RS) having a corresponding TRP identifier (ID) to a scheduled entity. The scheduled entity may be configured with at least one TRP-specific medium access control (MAC) parameter. The scheduled entity may receive the TRP-specific BFD-RSs and respective TRP IDs associated therewith. The scheduled entity may measure each BFD-RSs and count beam failure instances associated with each TRP ID. The scheduled entity may transmit a beam failure recovery request (BFRQ) associated with the respective TRP ID in response to a predetermined quantity of respective TRP-specific BFD-RS measurements of at least one of the respective TRP-specific BFD-RSs being less than a predetermined value. A scheduling entity may receive the BFRQ, where the at least one TRP-specific MAC parameter was used to trigger the BFRQ.

Abstract: Certain aspects of the present disclosure provide techniques for sidelink synchronization in a network. A method that may be performed by a remote user equipment (UE) includes determining at least one synchronization priority associated with synchronization signals for synchronizing to a network, determining relay capability information associated with multiple relay UEs, selecting one relay UE of the multiple relay UEs, based on the synchronization priority and relay capability, and synchronizing to the network using at least one synchronization signal received from the selected one relay UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a first synchronization signal associated with a first beam, and receive, from the base station and based at least in part on the first synchronization signal, scheduling information. Accordingly, the UE may receive, from the base station and based at least in part on the scheduling information, first system information associated with the first beam. The first system information may be distinct from second system information associated with a second beam. Additionally, or alternatively, the UE may receive the first system information using one or more first reception parameters that are distinct from one or more second reception parameters for the second system information associated with the second beam. Numerous other aspects are provided.

Abstract: A method, apparatus, and computer-readable medium for wireless communication are provided. A second user equipment (UE) receives a paging message for a first UE from a base station while in a radio resource control (RRC) idle mode or an RRC inactive mode and transmits the paging message from the second UE to the first UE over sidelink. A method, apparatus, and computer-readable medium for wireless communication at a base station are provided. The base station determines to page a first UE in an inactive state or an idle state and transmits a paging message for the first UE to a second UE in a radio resource control (RRC) idle mode or an RRC inactive mode, the paging message to be relayed to the first UE over sidelink.

Abstract: Aspects presented herein may enable a base station to page a target UE in an idle mode via a relay UE. In one aspect, a first UE receives, from a base station, a paging relay request message including paging information for at least a second UE, each paging information including a UE identity for the second UE and a paging type. The first UE transmits a paging message from the first UE to the second UE over sidelink. In another aspect, a base station generates a paging relay request message including paging information for at least a second UE, the paging information indicating a UE ID for the second UE and a paging type. The base station transmits, to a first UE, the paging relay request message, the paging relay request message indicating a request for the first UE to relay paging information to the second UE over sidelink.

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) based on physical (PHY) layer or medium access layer (MAC) layer measurement procedures. An example method generally 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, participating in a physical (PHY) layer or medium access control (MAC) layer measurement procedure with one or more cells in the set of cells, receiving PHY layer or MAC layer mobility signaling based on participating in the PHY layer or MAC layer measurement procedure, and updating a subset of activated cells for serving the UE based on the mobility signaling.
