Abstract: A method of wireless communication includes performing, by a user equipment (UE) device, a channel sensing operation during a first window of a frame period associated with a wireless communication network. Performing the channel sensing operation includes performing a direction-based scan of one or more beams associated with the wireless communication network, and the channel sensing operation is included in a joint sensing operation performed with a base station. The method further includes, based at least in part on a result of the channel sensing operation, determining whether to perform, during a second window of the frame period, one or more communication operations with the base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a device (e.g., a user equipment (UE)) may obtain a configuration message indicating one or more neural network models from abase station. The UE may then obtain an indication of a sequence of operations for a signal processing procedure for a neural network model of the one or more neural network models. In some examples, the signal processing procedure includes an input pre-processing procedure or an output pre-processing procedure. Upon obtaining a signal from a base station, the UE may perform the signal processing procedure on the received signal for the neural network model according to the sequence of operations.

Abstract: Aspects presented herein may enhance the configuration of the scheduling offset for communication devices within a channelized frequency band. In one aspect, a UE receives a PDCCH including a scheduling offset parameter. The PDCCH schedules one of a PDSCH for reception in a first sub-band within a BWP or provides an uplink scheduling grant of a PUSCH for transmission in a second sub-band within the BWP. The UE communicates with a base station based on one of a slot for receiving the PDSCH based on the first sub-band within the BWP and the scheduling offset parameter when the PDCCH schedules the PDSCH, or a slot for transmitting the PUSCH based on the second sub-band within the BWP and the scheduling offset parameter when a PUCCH is used to schedule the PUSCH.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first sensing signal of a radio frequency (RF) sensing procedure at a first transmit power. The UE may receive, from a base station at least in part in response to the first sensing signal, a power control message for sensing signals of the RF sensing procedure. The power control message may indicate a power control strategy for transmitting sensing signals of the RF sensing procedure. The UE may then transmit, at a second transmit power based on the received power control message, a second sensing signal of the RF sensing procedure.

Abstract: A method, an apparatus, and a computer program for wireless communication that allows for greater scheduling flexibility of physical resources are disclosed. A UE determines a time division duplex (TDD) frame structure for a plurality of frames, where the plurality of frames include a plurality of uplink (UL) subframes and a plurality of downlink (DL) subframes. The UE determines whether a control signaling instance is scheduled during an UL subframe of the plurality of UL subframes, wherein the control signaling instance is scheduled periodically and the control signaling includes at least one of a random access channel, an uplink control channel, a sounding reference signal (SRS), or a scheduling request (SR). The UE communicates the control signaling instance if the control signaling instance is scheduled during an UL subframe.

Abstract: Methods, systems, and devices for wireless communication are described that provide for reduced timing between certain downlink communications and responsive uplink communications relative to certain legacy systems (e.g., legacy LTE systems). A user equipment (UE) or base station may be capable of operating using two or more timing configurations that each include an associated time period between receipt of a downlink communication (e.g., a grant of uplink resources or shared channel data) and a responsive uplink communication (e.g., an uplink transmission using the granted uplink resources or feedback of successful reception of the shared channel data). In cases where a UE or base station are capable of two or more timing configurations, a timing configuration for a transmission may be determined and the responsive uplink communication transmitted according to the determined timing configuration.
