Abstract: In an embodiment, a user equipment (UE) receives, from a fixed reference node, at least one round-trip propagation time (RTT) ranging scheduling message indicating a set of downlink (DL) ranging resource assignments and a set of uplink (UL) ranging resource grants, receives one or more DL ranging signals from the fixed reference node on a first set of resources identified by the set of DL ranging resource assignments, and transmits one or more UL ranging signals to the fixed reference node on a second set of resources identified by the set of UL ranging resource grants.

Abstract: An integrated access and backhaul (IAB) central unit may receive, for a first TAB node, at least one of a first indication of a first capability to provide a cell-specific component of a time difference between a distributed unit transmission of a signal from the first IAB node and a reception of the signal at a child node of the first TAB node (T_delta) or a second indication of a second capability to synchronize with a parent node of the first IAB node based on a received T_delta. The central unit may determine the first capability and the second capability of the first IAB node based on at least one of the first indication or the second indication. The central unit may determine a location of the first IAB node within a network topology based on the first capability and the second capability.

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: Certain aspects of the present disclosure provide techniques for autonomous beamforming configuration change. A method that may be performed by a wireless node includes determining a communication mode to be used for communication by the wireless node, wherein the determining of the communication mode includes determining whether the communication is associated with multiple simultaneous communications with one or multiple other wireless nodes. The method may also include determining a beamforming configuration to be used for the communication based on the communication mode, and communicating in accordance with the communication mode using the beamforming configuration.

Abstract: Various aspects of the present disclosure generally relate to indicating beams for user equipment beam reporting. In some aspects, a user equipment (UE) may receive, from a base station, an indication of a plurality of candidate beams on which the base station is able to simultaneously transmit communications to the UE, and determine a first beam and a second beam from among the plurality of candidate beams, based at least in part on one or more measurements of the plurality of candidate beams. The UE may transmit an indication of the first beam and the second beam to the base station, and receive communications simultaneously on the first beam and the second beam. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for processing transmissions with multiple beams. For example, the techniques may be implemented in wireless systems in which any type of network entity (gNB or transmission reception points TRPs) send directional transmissions to user equipments (UEs) that receive the directional transmissions with receive beams.

Abstract: A first apparatus may determine that a DU function of a child IAB node is to transition between a first set of resources associated with an MT function of the child IAB node and a second set of resources associated with the DU function. The first apparatus may further configure a guard period associated with the transition time based on the first set of resources and based on the second set resources. A second apparatus determine to transition between a first set of resources associated with an MT function of the second apparatus and a second set of resources associated with a DU function of the second apparatus at a transition time. The second apparatus may further transmit, to a parent IAB apparatus, information requesting a guard period associated with the transition time based on the transition between the first set of resources and the second set resources.

Abstract: A relay supporting multiple relay modes is provided. The relay transmits capability information to a base station, the capability information indicating support for a first relay mode and a second relay mode. The relay determines a mode of operation, either on its own or based on an indication of a mode of operation from the base station, wherein the mode of operation comprises the first relay mode or the second relay mode. The relay communicates with at least one of the base station or another wireless device based at least in part on the determined mode of operation.
