Abstract: Methods, systems, and devices for wireless communication are described. A mobile wireless node (e.g., a mobile integrated access and backhaul (IAB) node) may transmit a control message to a parent wireless node indicating one or more supported network connectivity modes. A network connectivity mode may provide network connectivity to one or more user equipments (UEs) via the mobile wireless node when wireless backhaul connectivity is lost between the mobile wireless node and the parent wireless node. The parent wireless node may authorize the mobile wireless node to use a first network connectivity mode, and the mobile wireless node may communicate with a first UE in accordance with the first network connectivity mode. In this way, the mobile wireless node may use a network connectivity mode to extend coverage of a network to the first UE even if the first UE is outside of the coverage area of the network.

Abstract: Aspects of the present disclosure provide techniques for configuring multi-beam full-duplex communication that allows a device (e.g., user equipment (UE) or base station) to contemporaneously perform both uplink and downlink communication over the same frequency band. Because of the full duplex communication capability provided by the present disclosure, the NR system may achieve reduced latency and improved spectrum and resource efficiency, thereby accommodating a growing demands for the wireless communication. The full duplex communication capability may be achieved by implementing downlink control information (DCI) format that specifies to the UE the beam assignments for contemporaneous transmission (Tx) and reception (Rx). Particularly, beams may be selected such that the beam(s) assigned for communication are independent and uncorrelated, and therefore provide sufficient beam diversity in order to mitigate the limitations of current systems, including self-interference that has hindered implementation of full duplex communication in current systems.

Abstract: The present disclosure provides for a configuration that enables an apparatus to determine beam pairs for full duplex communication based on a cross-link interference procedure. The apparatus determines a subset of receive beams based on a beam measurement process, where each receive beam is associated with a different antenna array panel. In some aspects, the apparatus performs a channel measurement process based on the subset of receive beams. The apparatus sweeps through transmitted sounding reference signals from a same transmit beam corresponding to each receive beam of an antenna array panel and receives the transmitted sounding reference signals incrementally through other receive beams associated with other antenna array panels. The apparatus measures a self-interference for at least one beam pair of the subset of receive beams based on a received sounding reference signal. The apparatus selects one or more beam pairs based on a self-interference measurement or a signal-to-interference-plus-noise ratio.

Abstract: Aspects of the disclosure relate to a user equipment (UE) that receives a timing advance command from a network access node, sends a value indicative of a timing advance capability to the network access node, adjusts a timing advance indicated by the timing advance command based on the timing advance capability to yield an adjusted timing advance, and transmits an uplink signal to the network access node using the adjusted timing advance. Further aspects relate to a network access node that transmits a timing advance command to a user equipment (UE), receives a value indicative of a timing advance capability of the UE, and receives an uplink signal adjusted by a timing advance according to the timing advance capability of the UE. The timing advance capability may indicate that the UE has, or does not have, a capability to adjust the timing advance indicated by the timing advance command.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an uplink trigger (ULT) message that indicates a request for a network entity to transmit a system information message including timing information for the UE. In response to the ULT message, the UE may receive the system information message indicating a timing advance (TA) command applicable to the UE. In some examples, the system information message may indicate that the TA command is applicable to a group of UEs that include the UE and one or more additional UEs. In some other examples, the system information message may indicate the TA command and a set of one or more additional TA commands, each applicable to a respective additional UE. The UE may communicate with the network entity according to a timing based on the TA command received via the system information message.
