    Abstract: Certain aspects of the present disclosure provide techniques for reporting of a beam correspondence state. Certain aspects provide a method for wireless communication by a first wireless device. The method includes, based on detecting the occurrence of a triggering event, determining one or more beam correspondence states for one or more beams or portions of beams used by the first wireless device for communication. The method further includes transmitting one or more indications of the one or more beam correspondence states to a second wireless device, wherein the one or more indications of the one or more beam correspondence states indicate whether the first wireless device has the capability of beam correspondence between the one or more beams and corresponding one or more transmit or receive beams used by the first wireless device for communication.

    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 are described that support node connection techniques in wireless systems, such as relay node connections in a wireless backhaul network. A first node, which may be a new node or a node seeking to re-establish a connection, may initiate a connection establishment through transmission of a synchronization signal (SS). The first node, responsive to the SS transmission, may receive a response signal from one of the other nodes, and may establish a link with the other node. In some cases, the response signal may be an SS transmission from the other node, and the first node may transmit a random access request to the other node to initiate establishment of the link. In other cases, the response signal may be a random access request from the other node to initiate establishment of the link.

    Abstract: Methods, systems, and devices for wireless communications are described that provide for resource allocation in an integrated access and backhaul (IAB) network. A relay node in an TAB network may be assigned a first resource partition that is different from a second resource partition for the child and parent nodes. Based on a resource configuration (e.g., for a slot) of the second resource partition, the relay node may opportunistically utilize the second resource partition for communications. For instance, the relay node may determine a direction table based on the resource configurations of the child and parent nodes, which may be used to perform uplink or downlink communications in one or more symbols of the second resource partition. The relay node may also identify flexible symbols as free or non-free when determining the direction table.
