Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine a default operating mode based on the geographic location (e.g., zone) of the base station, for user equipment (UEs) operating in that zone to use. The operating mode may be a full duplex (FD) operating mode or a half duplex (HD) operating mode. A UE operating in the zone may receive, from the base station, an indication of the default operating mode corresponding to the zone, and may select an operating mode based on the indication. The mode selected by the UE may be the same as or different than the indicated default operating mode. For example, the UE may determine to use either FD mode or HD mode based on operation parameters, interference measurements, signaling from a base station or other UEs, one or more measurement thresholds, or some combination thereof.

Abstract: Aspects described herein relate to resource allocation in an integrated access and backhaul (IAB) system. In an example, the aspects include determining, by a central unit (CU), a configuration of not-available (NA) resources for a parent node, wherein the NA resources of the parent node correspond to a set of one or more resources configured at the parent distributed unit (DU) as being unavailable for uplink and downlink communications between the parent DU and a child node; and modifying, by the CU, the first child DU resource configuration to create a modified child DU resource configuration.

Abstract: Aspects of the present disclosure provide techniques for packet delay budget (PDB) coordination between two integrated access and backhaul (TAB) nodes for a radio link control (RLC) channel in an TAB network. An TAB node may dynamically adjust its configured one-hop RLC channel PDB based on channel conditions or buffer loading associated with the TAB node. The TAB node may then indicate bonus PDB at a next-hop node or request additional PDB from the next-hop node.

Abstract: Certain aspects of the present disclosure provide techniques for beam pair selection. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), an indication to report one or more beam pairs to be used for full-duplex (FD) communication based on a timing constraint, wherein the timing constraint comprises a constraint on a time difference between receptions, at the UE, of a downlink (DL) signal and an uplink (UL) signal for each of the one or more beam pairs and transmitting a report specifying the one or more beam pairs in accordance with the indication, in accordance with aspects of the present disclosure.

Abstract: This disclosure provides systems, apparatus, methods, and computer-readable media for beam switching by a repeater node that forwards communications from one of a first node or a second node to the other of the first node or the second node. For example, after a change of position by the second node, the first node may provide the repeater node an instruction to perform a beam change operation to communicate with the second node. In some aspects, performing the beam change operation by the repeater node may improve reliability of wireless communications, such as by focusing signal energy in a particular direction. Further, a beam change delay time interval or a scheduling of the beam change delay time interval may be selected based on scheduling associated with other nodes, which may reduce a number of messages sent to the repeater node (such as by reducing instructions to change beam directions).

Abstract: Apparatus, methods, and computer-readable media for facilitating beam training with relay link are disclosed herein. An example method for wireless communication at a control node includes determining a first set of measurements associated with at least one set of beam pairs. In some examples, the at least one set of beam pairs is associated with a wireless backhaul link between a first wireless device and a relay device, a first relay access link portion between the first wireless device and the relay device, or a second relay access link portion between the relay device and at least one second wireless device. The example method also includes configuring at least one subset of beam pairs of the at least one set of beam pairs based on the first set of measurements. Additionally, the example method includes transmitting information indicating the at least one subset of beam pairs to the relay device.

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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select a random access channel (RACH) occasion (RO) based on one or more channel quality thresholds, such as reference signal received power (RSRP) thresholds. A base station may determine a set of RO types for receiving RACH transmissions. The base station may determine a channel quality threshold for each RO type. The base station may broadcast a configuration indicating the RO types and the associated channel quality thresholds. The UE may receive the configuration and measure a channel quality between the UE and the base station. Based on the measured channel quality, the UE may determine which RO types are available based on the indicated channel quality thresholds, and select an RO for transmitting a RACH preamble to establish a connection with the base station based on the available RO types.

Abstract: Aspects of the present disclosure provide techniques for addressing scenarios where the minimum transmit power supported by a wireless node (e.g., an Integrated Access and Backhaul (IAB) node) is above a minimum value specified by a standard. In some cases, the node may signal information regarding its power configuration so a network entity of the may take it into account (e.g., when allocating or scheduling resources). The power configuration may include an indication of the minimum transmit power supported by the node and/or an indication of a guard band that may help the IAB control adjacent channel leakage.
