Abstract: Aspects presented herein may enable a remote UE to notify a base station about the availability of a relay UE that is not connected to the base station. In one aspect, a remote UE transmits, to a relay UE, a relay request via sidelink, the relay UE being in an RRC inactive mode. The remote UE receives, from the relay UE via the sidelink, an indication of relay availability in response to the relay request. The remote UE receives, from a base station, a configuration for relay of communication from the base station over the sidelink between the remote UE and the relay UE. The remote UE transmits or receives user data from the base station through the relay UE based on the configuration.

A method of wireless communication performed by a first sidelink user equipment (UE) may include receiving, from a second sidelink UE, a request to monitor for at least one of a paging signal associated with the second sidelink UE or a wakeup signal (WUS) associated with the second sidelink UE, monitoring for the at least one of the paging signal or the wakeup signal based on the request, receiving, from a base station (BS), the at least one of the paging signal or the wakeup signal, and transmitting, to the second sidelink UE, the at least one of the paging signal or the wakeup signal.

Abstract: Methods, systems, and devices for wireless communications are described in which wireless nodes may use licensed shared radio frequency spectrum band for communications and one or more neighboring networks may use a same licensed shared radio frequency spectrum band. A second network of the one or more neighboring networks may have priority of use of the licensed shared radio frequency spectrum band within a particular geographic area. Disclosed techniques provide that nodes of each network may indicate an identification of the network, a network priority, or both, in over-the-air signaling. Wireless nodes may determine if another neighboring network is present based on the over-the-air signaling, may determine whether the other network has a higher priority, and may adjust one or more transmissions in the event that a higher priority network is identified, such as through reducing transmission power.

Abstract: Wireless communications systems and methods related to UE cooperation are provided. A base station (BS) may assist a UE in discovering and cooperating with other UEs. A BS may collect information from candidate cooperative UEs such as UE capability and availability. This information may be broadcast to other UEs or may be transmitted to a UE at the UE's request. The UE may, upon receipt of this information, use it to aid in discovering the candidate cooperative UEs and/or establishing a connection.

Abstract: Aspects relate to sharing a channel occupancy time (COT) initiated by a network access node (e.g., a base station) with one or more wireless communication devices for sidelink communication between the wireless communication devices. In this example, the network access node can transmit a COT structure indication (COT-SI) to the wireless communication device(s) indicating the COT resources (e.g., time and frequency resources) of the COT that may be shared with sidelink. In some examples, the wireless communication device can receive a message from the network access node including a COT sharing indicator indicating whether COT sidelink sharing is enabled or disabled.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support system information design for systems that support spectral sharing and network entity sharing for multiple mobile network operators (MNOs). For example, a UE may monitor a radio frequency (RF) spectrum for synchronization signal blocks (SSBs) from a network entity and associated with an MNO. The RF spectrum and the network entity may be shared by the MNO and one or more other MNOs. The UE may receive the SSBs via a broadcast channel within the RF spectrum. The SSBs may be shared SSBs that may include dedicated system information associated with the MNO and shared system information associated with multiple MNOs. The UE may communicate via the RF spectrum according to the dedicated system information and the shared system information.

A user equipment (UE) may be configured to indicate to a base station a distribution of transmit antennas and receive antennas across a set of antenna panels, and the base station may configure resource sets for reference signal transmissions from the antenna panels based on the indicated distribution. In a first example, the UE may be configured to indicate a respective number of transmit antennas and receive antennas at each antenna panel. In a second example, the UE may be configured to indicate a sum of transmit antennas and a sum of receive antennas across all antenna panels, along with information on how the transmit antennas and receive antennas are distributed. Based on the indication, the base station may configure resource sets for reference signal transmission on sets of ports in resources of the resource sets.

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: A method of wireless communication by an initiating device, includes acquiring a channel occupancy time (COT) including multiple subsets of COT sharing resources. Each of the subsets includes fewer resources than the entire COT. The method also includes configuring a first responding device with a first of the subsets of COT sharing resources. The method further includes configuring a second responding device with a second of the subsets of COT sharing resources. A method of wireless communication by a responding device receives, from an initiating device, a first subset of multiple subsets of channel occupancy time (COT) sharing resources. The first subset differs from a second subset of COT sharing resources configured for another device. The method also includes selecting transmission resources from the first subset of COT sharing resources in response to detecting the initiating device acquired the COT, and then transmitting data on the selected transmission resources.

In some aspects, a user equipment (UE) or a network entity may determine one or more time intervals for sounding reference signal (SRS) transmissions from a type of link, such as a link with another UE or a link with the network entity, used to communicate control signaling that triggers the SRS transmissions for the UE. A time interval in which the UE may not expect to transmit SRSs after receiving the control signaling, a time interval between the control signaling and the associated SRSs, a time interval between the control signaling and reception of one or more channel state information reference signals (CSI-RSs) used for precoding the SRSs, or any combination thereof, may be increased by an additional offset when the control signaling triggering the SRSs is received via the cooperative link.
