Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a random access channel (RACH) message to a first distributed unit (DU) via a cell supported by the first DU to support acquisition of timing advance (TA) information prior to switching to the cell. A second DU serving the UE may identify and indicate the TA information to the UE based on the UE transmitting the RACH message indicating a RACH preamble allocated to the second DU by a central unit (CU). The RACH preamble may be included in a set of preambles indicated to the CU by the first DU for TA information acquisition. Alternatively, the UE may be identified by the first DU based on a UE-specific RACH preamble, a RACH preamble, RACH occasion (RO) pair, or a request by the second DU to order the UE to transmit the RACH message.

Abstract: Methods, systems, and devices for wireless communication are described. A first network node may receive information via a first cell. The information may indicate a resource allocation for transmission of an initial uplink message via a second cell. The initial uplink message is a first uplink transmission scheduled to occur between the first network node and a second network node after a handover of the first network node from the first cell to the second cell. The first network node may receive a command via the first cell. The command may trigger the handover of the first network node from the first cell to the second cell. In response to the command message, the first network node may transmit the initial uplink message via the second cell.

Abstract: A wireless device is configured to. receive, from a cell, an indication of invalidity for at least one of: a radio resource control (RRC) message for the wireless device updating a layer 1/layer 2 triggered mobility (LTM) candidate configuration, or a packet data protocol convergence (PDCP) sequence number (SN). The wireless device skips the PDCP SN for PDCP reordering.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a repeater may receive a side control configuration from a radio access network (RAN) node. The repeater may receive an indication of a validity time associated with the side control configuration. The repeater may forward signaling to or from the RAN node based on the side control configuration for a duration of the validity time. Numerous other aspects are described.

Abstract: A method for wireless communication at a user equipment (UE) is provided. In the method, the UE receives, via radio resource control (RRC), a configuration of multiple candidate cells for layer 1 (L1) or layer 2 (L2) inter-cell mobility from a network entity, and receive information about an L2 reset when switching between the multiple candidate cells from the network entity. Then, the UE performs a serving cell switch within the candidate cells for the UE in response to L1 or L2 signaling, and resets or reuses an L2 cell configuration based on the information in response to the serving cell switch.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network entity, an indication of a required minimum value for a time offset associated with a communication with the network entity, wherein the required minimum value for the time offset is associated with communicating with the network entity via an assisting node. The UE may receive, from the network entity, an indication of an offset value for the time offset based at least in part on the required minimum value for the time offset. The UE may communicate with the network entity via the assisting node in accordance with the offset value. Numerous other aspects are described.

Abstract: Example implementations include a method, apparatus, and computer-readable medium of wireless communication for backhaul transport of non-F1 traffic between an integrated access and backhaul (IAB) node and a. IAB-donor-central unit (CU). The IAB-node may have a connection with the IAB-donor-CU. The IAB-node may provide the IAB-donor-CU with an indication of a non-F1 type of traffic for backhauling between the IAB-node and the IAB-donor-central unit. The IAB-node may receive, from the IAB-donor-CU, a configuration that maps the non-F1 type of traffic to an uplink transport channel at the IAB-node. The IAB-node may transmit uplink non-F1 traffic to the IAB-donor-CU over the uplink transport channel based on the configuration.

Abstract: Certain aspects of the present disclosure provide techniques for exchanging information about transmission reception points (TRPs) between two or more network entities, such as between a distributed unit (DU) and a central unit (CU) in one example, or between a gNodeB (gNB) and a location management function (LMF) in another. For example, a first network entity may determine an update of TRP information of one or more TRPs associated with the first network entity. The first network entity then transmits, in a TRP information message, to a second network entity to indicate the update of TRP information.

Abstract: Aspects presented herein may enable a transmitting entity, such as a base station, to indicate to one or more receiving entities that SSBs of one or more cells (which may include the transmitting entity) are to be transmitted with modified configurations. The method may also enable the transmitting entity to transmit modified SSBs to enable network energy saving. In one aspect, a base station configures one or more cells of a plurality of cells with one or more modified SSBs associated with an ES mode. The base station transmits an indication of the one or more cells associated with a transmission of the one or more modified SSBs, the transmission of the one or more modified SSBs corresponding to an ES mode at the one or more cells, the one or more cells being associated with the base station or at least one other base station.
