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 child node may receive a message, from a serving or neighboring cell, that includes an indication of an intended time division duplex (TDD) configuration for the serving or neighboring cell. The indication may include downlink and uplink indicators for at least one slot used within the intended TDD configuration. Accordingly, the child node may determine a symbol to use within a TDD configuration for the child node, based at least in part on receiving the message. Numerous other aspects are provided.

Abstract: An integrated access and backhaul (IAB) node may transition between use of a mobile termination (MT) function at the wireless device and use of a distributed unit (DU) function. The IAB node may schedule communication using the DU function of the wireless device based on whether one or more guard symbols are provided for an allocation from a parent node for the MT function.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may identify one or more parameters indicating a mobility of a served node relative to a serving node. The wireless node may classify the served node within a category, among a plurality of categories, based at least in part on the one or more parameters. In some aspects, the plurality of categories may include at least a first category for served nodes that have a low mobility relative to the serving node and a second category for served nodes that have a high mobility relative to the serving node. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications at a first wireless node in a wireless communications system are described. The techniques may enable a first wireless node (e.g., an integrated access and backhaul (IAB) node in an IAB system) to establish a communications link with a second wireless node. The first wireless node may receive, via a reception beam of the first wireless node, an interfering signal from an aggressor wireless node. The first wireless node may perform an interference measurement of the interfering signal at the first reception beam. The first wireless node may transmit a report indicating the interference measurement to the second wireless node. The second wireless node may schedule communications based on the interference measurement. In some examples, the report may indicate one or more parameters of the interfering signal. In some examples, the report may correspond to one or more beams.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may receive, from a control node, information identifying a slot configuration pattern for a wireless communication link between the wireless node and another wireless node. For example, the information identifying the slot configuration pattern may indicate one or more symbols that are configured to support full-duplex communication. The wireless node may communicate with the other wireless node in the one or more symbols configured to support full-duplex communication in accordance with the slot configuration pattern. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a child node of a parent node in an integrated access backhaul (IAB) network may determine communication information that includes one or more of a schedule or a configuration for a communication to be transmitted by the child node. The child node may be an IAB node, and the parent node may be an IAB donor or an intervening IAB node between the IAB node and an IAB donor. The child node may transmit the communication information to the parent node via a wireless backhaul link between the child node and the parent node. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described to enable a mobile access node to enter a new power state based on detection of a second access node. The second access node may be detected by the mobile access node or a central unit (CU). The mobile access node or the CU may determine for the mobile access node to enter a new power state and may notify the other of the determination. The mobile access node may enter a lower power state if the second access node is within a defined proximity or if one or more thresholds are exceeded. The mobile access node may enter a higher power state if no other access nodes are within the defined proximity or if the one or more thresholds are not exceeded. Configuration parameters for a power state change procedure may be configured by control signaling from a CU.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive, via a mobile termination (MT) and from a central unit (CU) of a donor network node, a first message that includes first information associated with a token. The network node may transmit, via a distributed unit (DU) and to the CU of the donor network node, a second message that includes second information associated with the token, to thereby indicate collocation of the MT and the DU. Numerous other aspects are provided.

Abstract: An apparatus acquires random access information for at least one of a donor node serving the node or a neighbor cell of the node and determines one or more random access parameters for a device to perform a random procedure with the node. The one or more random access parameters are based on the acquired random access information. The apparatus may be an IAB node.
