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: Aspects are provided which allow a network entity to receive an uplink transmission from a UE in UE DTX or cell DRX based on dynamic activation or deactivation of a DTX configuration or an associated uplink transmission configuration with respect to DTX. In some examples, the UE receives a DTX configuration associated with a UE transmission configuration and indicating an active time duration for a UE transmission associated with the UE transmission configuration. The UE also receives the uplink transmission configuration, such as an SR configuration, and a semi-static or dynamic indication of an active status of the DTX configuration or the uplink transmission configuration with respect to the DTX configuration. Afterwards, the UE transmits the UE transmission during the active time duration indicated in the DTX configuration based on the active status. As a result, less uplink transmission monitoring may result at the base station, providing network energy savings.

Abstract: Methods, systems, and devices for wireless communications are described that provide for cell access procedures based on multiple types of discovery signals that may be transmitted by network entities operating in an energy saving (ES) mode. A user equipment (UE) may establish wireless connectivity via a first network entity and receive a discovery signal from a second network entity that contains less information than a synchronization signal block (SSB) for use in a cell access procedure. The UE may transmit, based at least in part on one or more conditions associated with the discovery signal being satisfied, a trigger signal to the ES-mode second network entity to transmit a SSB for use in the cell access procedure. The UE may monitor for the SSB based at least in part on the trigger signal, and perform the cell access procedure based at least in part on the SSB.

Abstract: Aspects of the present disclosure provide mechanisms for transmitting discovery signals to enable discovery of a cell. Synchronization signal blocks (SSBs) carrying the cell identifier of the cell may then be transmitted either on-demand or with a higher periodicity than discovery signals. The discovery signals and SSBs may be transmitted within a same bandwidth part and on at least overlapping sets of frequency resources.

Abstract: Methods, systems, and devices for wireless communications are described. A first network entity (e.g., a distributed unit (DU)) may receive, from a second network entity (e.g., a centralized unit (CU)), a control message indicating a common discontinuous reception (C-DRX) configuration associated with a set of user equipments (UEs) communicatively coupled to the first network entity, where the C-DRX configuration indicates a time period including an active duration and an inactive duration. The first network entity may then communicate with two or more of the set of UEs in accordance with the indicated C-DRX configuration during the active duration of the time period of the C-DRX configuration.

The scheduled node may transmit, to a scheduling node (e.g., a base station), a LBT status report indicative of the status of each LBT channel in the set of one or more LBT channels. The scheduling node may schedule, via a second scheduling grant, a second set of one or more LBT channels based on the status of each LBT channel indicated in the LBT status report.

A first node of an IAB network may determine a routing address for a second node, and communications may be transmitted to the second node based on the routing address to allow for coordination between the first and second nodes. The first node may detect a discovery signal of a second node, and may determine to communicate with the second node based on the discovery signal. The first node may obtain the routing address based on one or more of transmitting a request for the routing address to a third node, establishing a sidelink connection with the second node to obtain the routing address, receiving a mapping between routing addresses and cell IDs that are transmitted in discovery signals, or any combinations thereof.

Abstract: In certain aspects, the disclosure is directed to a user equipment (UE) configured for wireless communications with a network node. The UE may include a memory comprising instructions, and one or more processors configured to execute the instructions. In some examples, the UE may transmit, to a network node, an indication of an expected communication. In some examples, the UE may receive, from the network node, updated scheduling in response to the indication of the expected communication. For example, the UE may predict a future sidelink/uplink communication based on whether the UE expects data for a future uplink transmission. If the UE expects that it will have data for a future uplink transmission, the UE may notify the network node so that the network node can enter into a low power state until the future transmission, then provide the UE with a sidelink/uplink grant for the future uplink transmission.
