Abstract: Wireless communications systems and methods related to channel access in a shared radio frequency band in an unlicensed spectrum or a shared spectrum are provided. A wireless communication device determines a channel access procedure based on whether one or more channel access conditions are satisfied for accessing an unlicensed frequency band. The one or more channel access conditions are associated with at least one of sensing across multiple channel occupancy times (COTs), a transmission beam characteristic, a transmit power, a transmission duty cycle, or a beam dwell time. The wireless communication device transmits, based on the channel access procedure, a communication signal in the unlicensed frequency band.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for detecting when a control link between a user equipment (UE) and a base station is lost and recovering the control link. In one example, a UE may detect that a control link with a base station is lost based on a timer or counter expiring or based on failing to receive signaling from the base station. In another example, a UE may be configured to transmit uplink transmissions to a base station to maintain a control link with the base station, and the base station may detect that a control link with the UE is lost if the base station fails to receive one or more uplink transmissions from the UE. If the control link is lost, the base station and the UE may communicate to re-establish the control link.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information for a received signal strength indication (RSSI) measurement, the configuration information indicating a transmission configuration indication (TCI) state configuration for the RSSI measurement. The UE may perform the RSSI measurement based at least in part on the TCI state configuration. The UE may transmit a measurement report of the RSSI measurement. Numerous other aspects are described.

Abstract: A method of wireless communication, by a user equipment (UE), includes determining whether conforming input has been received for each of multiple input branches to a neural network. Each input branch represents a different modality of input features to the neural network. The method also includes replacing an activation with a replacement activation for at least one neural network layer of each of the input branches associated with input determined to be non-conforming input. The method further includes predicting an output parameter based on conforming input received at each input branch and the replacement activation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure one or more linear combinations, of a set of beams, from a radio access network (RAN) node. Accordingly, the UE may transmit a report, based at least in part on measuring the one or more linear combinations, to the RAN node. The one or more linear combinations may be indicated in one or more rules stored in a memory of the UE or may be indicated in a system information block or a radio resource configuration message. Numerous other aspects are described.

Abstract: Wireless communications systems and methods related to acknowledgement/negative-acknowledgement (ACK/NACK) transmissions with different reliability levels are provided. A user equipment (UE) receives, from a base station (BS), a negative acknowledgement (NACK) transmission configuration. The UE receives, from the BS, a data transmission. The UE transmits, to the BS, a physical uplink control channel (PUCCH) signal including a NACK for the data transmission based on the received NACK transmission configuration. Other aspects and features are also described.
