Abstract: Certain aspects of the present disclosure provide techniques for channel access in an unlicensed spectrum. An example method of wireless communication by a user equipment includes receiving a resource grant indicating a plurality of resource candidates for an uplink signal. The method also includes sensing for energy, in response to the resource grant, over one or more of the resource candidates in a first sensing occasion before a transmission occasion of the uplink signal. The method further includes transmitting, during the transmission occasion, the uplink signal using a subset of the resource candidates selected based at least in part on energy sensed in the first sensing occasion.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at an integrated access and backhaul (TAB) node. The TAB node receives a first delay parameter and a second delay parameter associated with a packet, the first delay parameter being associated with a discard determination for the packet and the second delay parameter being associated with scheduling the packet for transmission. The TAB node performs a discard decision for the packet based on the first delay parameter associated or schedules the packet for transmission to a second TAB node or a user equipment (UE) using a second delay parameter associated with the packet. A central unit (CU) of an TAB network may indicate, to an TAB node, the second delay parameter for scheduling a packet and the first delay parameter for determining whether to discard the packet.

Abstract: Aspects of the present disclosure provide techniques for interference measurements based on a priority value in a network (e.g., an Integrated Access and Backhaul (IAB) network). Certain aspects provide a method for wireless communications. The method generally includes determining, at a first wireless node, a priority value associated with the first wireless node configured to serve one or more child nodes, determining occurrence of interference to communications of the first wireless node and/or a second wireless node, and taking one or more actions in response to the determination of the interference based on the priority value.

Abstract: Aspects of the present disclosure provide techniques for handover in an Integrated Access and Backhaul (IAB) network or other type of network. One example method which may be performed by a source base station (BS) includes: determining to migrate a child node from a first logical IAB-distributed unit (DU) of an IAB-node to a second logical IAB-DU of the IAB-node, wherein the first logical IAB-DU is associated with the source BS, and wherein the second logical IAB-DU is associated with a target BS; sending, to the target BS, context information of the child node served by the first logical IAB-DU in response to the determination; and indicating, to the target BS, a traffic mapping configuration at the IAB-node associated with the context information and a backhaul connection of the IAB-node.

Abstract: Methods, systems, and devices for wireless communications are described. A mobile integrated access and backhaul (IAB) node may transmit, to an IAB supported network, an indication of IAB capability. The mobile IAB node may also indicate to the IAB supported network a mobility status associated with the mobile IAB node. The IAB supported network may conditionally determine authorization for the mobile IAB node based on the mobility status, a subscription status, or both. The IAB supported network may transmit, to the mobile IAB node, instruction to operate in an IAB mode and perform the IAB operation. The mobile IAB node may communicate with one or more devices based on the instruction.

Abstract: Methods, systems, and devices for wireless communications are described. a first donor node may serve a relay node, which in turn may serve a child node. The first donor node may determine to transfer (e.g., via a handover procedure) the relay node to a second donor node. The first donor node may transmit a first context transfer request for the relay node to the second donor node, and may transmit a second context transfer request for the child node of the relay node to the second donor node. The first donor node may indicate a correlation between the two context transfers. The second donor node may identify the correlated context transfers, and may successfully perform a migration procedure for the relay node and any descendent devices or nodes based on the correlated context transfers.
