Abstract: Wireless communications systems and methods related to sharing channel occupancy time (COT) for a channel in an unlicensed 5G spectrum in an integrated access backhaul (IAB) network are provided. In some aspects, an IAB node of the IAB network may perform a channel access procedure to acquire the COT and share the COT with a parent IAB node and/or a child IAB node for the parent IAB node and/or child IAB node to communicate back with the COT initiating IAB node. The sharing of the COT with the parent IAB node and/or child IAB node may also include a sharing of the same COT between a distributed unit and a mobile terminal of the COT-initiating IAB node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node (e.g., a user equipment) may receive, from a second wireless node (e.g., a base station), a downlink signaling message indicating a synchronization signal block (SSB) grouping based at least in part on a full-duplex capability and transmission directions associated with the second wireless node. The first wireless node may configure, and the second wireless node may perform, a beam search and/or a self-interference measurement to identify at least one candidate downlink and uplink beam pair suitable for full-duplex operation based at least in part on the SSB grouping. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive, from a second wireless node, a round-trip time timing advance indicator, wherein the round-trip time timing advance indicator is different from a timing advance indicator used for an uplink transmission timing advance message. In some aspects, the first wireless node may synchronize a timing configuration of the first wireless node to at least one of the second wireless node or a third wireless node based at least in part on the round-trip time timing advance indicator. Numerous other aspects are provided.

Abstract: Aspects relate to establishing a signaling connection between a radio access network (RAN) node and a first scheduling entity. The RAN node may communicate in a dual connectivity (DC) mode of operation with the first scheduling entity (e.g., a secondary gNB) using a first radio access technology (RAT) and with a second scheduling entity (e.g., a master eNB) using a second RAT. The RAN node and the first scheduling entity may support sending information for a first signaling connection between the RAN node and the first scheduling entity over a second signaling connection through the second scheduling entity (e.g., when the second signaling connection is more reliable than the first signaling connection). To establish the second signaling connection, the RAN node and the first scheduling entity may signal support for the second signaling connection and exchange Internet Protocol information for the second signaling connection.

Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. For example, a communication system may include a repeater that relays communications between communication devices. The repeater determines a downlink gain value to use for one or more downlink initial access messages received at the repeater. The repeater determines an uplink gain value to use for one or more downlink initial access messages received at the repeater. The uplink gain value is based on the downlink gain value and a noise level related to a channel between the communication device and the repeater. The repeater receives a downlink initial access message, and applies the downlink gain value to the downlink initial access message. The repeater receives an uplink initial access message, and applies the uplink gain value to the uplink initial access message.

Abstract: An integrated access and backhaul (IAB) central unit may receive, for a first TAB node, at least one of a first indication of a first capability to provide a cell-specific component of a time difference between a distributed unit transmission of a signal from the first IAB node and a reception of the signal at a child node of the first TAB node (T_delta) or a second indication of a second capability to synchronize with a parent node of the first IAB node based on a received T_delta. The central unit may determine the first capability and the second capability of the first IAB node based on at least one of the first indication or the second indication. The central unit may determine a location of the first IAB node within a network topology based on the first capability and the second capability.

Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, a host wireless device may transmit a discovery message to a client wireless device. The client wireless device may transmit a random access channel (RACH) preamble on a first time domain resource to the host wireless device in response to the discovery message. The client wireless device may later transmit a second RACH message to the host device on a second time domain resource after the first time domain resource. The second time domain resource may be defined by a mapping from the first time domain resource. The host device may transmit a third RACH message establishing a communication session between the host wireless device and the client wireless device.

Abstract: Certain aspects of the present disclosure provide techniques for autonomous beamforming configuration change. A method that may be performed by a wireless node includes determining a communication mode to be used for communication by the wireless node, wherein the determining of the communication mode includes determining whether the communication is associated with multiple simultaneous communications with one or multiple other wireless nodes. The method may also include determining a beamforming configuration to be used for the communication based on the communication mode, and communicating in accordance with the communication mode using the beamforming configuration.
