Abstract: Wireless communications systems and methods related to routing communications in a multiple-relay environment are provided. A base station (BS) transmits, to one or more wireless communication devices, a reference signal configuration indicating one or more reference signal resources. The base station receives, from a first wireless communication device of the one or more wireless communication devices, a channel state report based on one or more reference signals in the one or more reference signal resources. The channel state report includes channel measurement information for one or more links, each link connecting a wireless communication device of the one or more wireless communication devices to a user equipment (UE). The BS transmits, to the UE via a second wireless communication device of the one or more wireless communication devices based on the channel state report, a data signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an uplink grant scheduling an uplink transmission that is not aligned with a fixed frame period (FFP) boundary configured for the UE. The UE may receive downlink control information (DCI) including an indication that the UE is to initiate a channel occupancy time (COT) acquisition in association with transmitting the uplink transmission. The UE may modify the indication based at least in part on the uplink transmission not being aligned with the FFP boundary and the indication indicating that the UE is to initiate the COT acquisition. The UE may transmit the uplink transmission based at least in part on the uplink grant and after the modification of the indication. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a fixed frame period (FFP) configured for the UE in a frame based equipment mode. The FFP configured for the UE includes one or more idle periods and a channel occupancy time that is offset from an FFP configured for a base station communicating with the UE over an unlicensed channel. The UE may refrain from transmitting over the unlicensed channel during the one or more idle periods. The one or more idle periods may at least partially overlap with a time period in which the base station refrains from transmitting over the unlicensed channel. Numerous other aspects are provided.

Abstract: In an aspect, a network component (e.g., BS, server, etc.) obtains measurement information associated with uplink signal(s) from UE(s), with the uplink signal(s) having reciprocity with one or more downlink beams of wireless node(s) (e.g., TRP, reference UE, etc.). The network component determines (e.g., generates or refines) a measurement (e.g., RFFP-P) model based on the measurement information. The network component provides the measurement (e.g., RFFP-P) model to a target UE. The target UE receives at least one signal (e.g., PRS) on the one or more downlink beams from the wireless node(s). The target UE processes the at least one signal (e.g., predicts target UE location) based at least in part on the measurement (e.g., RFFP-P) model.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a first network entity. The method generally includes generating beam forming weights (BFWs) based on channel estimates (CEs) based on precoded demodulation reference signals (DMRS), performing a reversion procedure, on the BFWs, based on precoding applied at a user equipment (UE) when transmitting the precoded DMRS, and transmitting, on a fronthaul (FH), a signal to a second network entity with beamforming using the BFWs.

Abstract: A method of wireless communication by a user equipment (UE) includes receiving, from a network device, a request to initiate gradient computations for a round of federated learning. The method also includes computing gradients in response to receiving the request to initiate gradient computation. The method further includes informing the network device of availability of the gradients. The method still further includes receiving, from the network device, information to enable transfer of the gradients to the network device. The method further includes transferring the gradients to the network device in response to receiving the information to enable transfer.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, an uplink request including an indication that data associated with the uplink request is delay sensitive. The UE may receive, from the base station, an uplink grant associated with a logical channel group including a logical channel for the data, wherein the logical channel group is associated with a higher priority than one or more other logical channel groups. The UE may transmit, to the base station and using the logical channel, the data, based at least in part on the uplink grant. Numerous other aspects are provided.
