    Abstract: Aspects of the present disclosure provide techniques switching a communication link for wireless systems with multiple parents, such as an Integrated Access and Backhaul (IAB) network or other type of network. In some cases, a node determines a partition of a number of desired guard symbols between a first parent node and a second parent node; sends, to the first parent node and to the second parent node, at least one indication of a partitioned number of the desired guard symbols for switching between the first parent node and the second parent node; receives at least one indication of a number of provided guard symbols from the first and second parent nodes; and switches a communication link from the first parent node to the second parent node in accordance with the at least one indication of provided guard symbols by the first parent node and the second parent node.

    Abstract: In some aspects, a wireless node in a wireless multi-hop network may receive, from a central unit in the wireless multi-hop network, a configuration indicating that a first wireless interface between the wireless node and a first parent node of the wireless node is to be used for a first traffic type, and that a second wireless interface between the wireless node and a second parent node of the wireless node is to be used for a second traffic type; configure a first connection with the first parent node via the first wireless interface and a second connection with the second parent node via the second wireless interface based at least in part on the configuration; and transmit or receive a communication using the first connection or the second connection based at least in part on a traffic type of the communication.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may receive an indication of a plurality of sets of reference signal identifiers, wherein each set of reference signal identifiers of the plurality of sets of reference signal identifiers identifies reference signals of candidate neighbor nodes associated with the set, and wherein each candidate neighbor node associated with the set is in a same operating mode, and transmit a measurement report based at least in part on measuring one or more reference signals identified in the plurality of sets of reference signal identifiers. Numerous other aspects are provided.

    Abstract: Efficient opportunistic communications in integrated access and backhaul (IAB) frameworks are provided allowing scheduling nodes and scheduled nodes to communicate within an allocated set of resources based on a different configuration than for non-opportunistic communications using a different set of resources. An additional set of available resources may be allocated for coordinated communications between a parent IAB-node and the child IAB-node. Resources within this available set are associated with a first configuration, and when prior coordination exists, the parent IAB-node and child IAB-node may communicate based on this first configuration over this available set of resources. However, when prior coordination does not exist, the parent IAB-node and child IAB-node may opportunistically communicate over the allocated set of resources based on a second configuration different than the first configuration. Using different configurations, power may be conserved and resources managed more efficiently in opportunistic communications where unsuccessful transmissions may be more likely.

    Abstract: Methods, systems, and devices for wireless communications are described that provide for multiple timing advance offsets that may be used in communications between wireless devices on a wireless communications system. A first timing advance offset may be a fixed offset that has a predetermined value or is selected from a set of available predetermined values, and a second timing advance offset may be adjustable by a wireless device. The second timing advance offset may be used in cases where relatively large distances between wireless devices are present in a system, where certain fixed timing advances are used in addition to or irrespective of a receiving devices propagation delay, where one or more parent nodes have an associated timing reference, or combinations thereof.

    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.
