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 first base station may sense a channel based at least in part on a sensing time period. The first base station may receive, from a user equipment (UE), a dynamic frequency selection (DFS) signal on the channel during the sensing time period. The first base station may determine to refrain from communicating on one or more of a beam associated with the DFS-assisted signal or the channel on which the DFS-assisted signal is received for a defined duration of time, based at least in part on an indication of the one or more of the beam or the channel being added to a non-occupancy list. Numerous other aspects are described.

Abstract: The apparatus of wireless communication is a UE. The UE out of coverage of any base station may operate in a VLP mode and set a signal transmission power to a first power level. The UE may detect and connect to a base station, switch the power mode of UE based on a power mode of the base station connected by the UE, and switch the signal transmission power from the first power level to the second power level greater than the first power level. When the UE detects equal to or more than two base stations, the UE may select the base station from the equal to or more than two base stations detected based on a condition and connect to the base station selected from the two detected base stations.
