Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, a network entity for wireless communications can transmit wide sensing signal beams in different directions to detect a target. The network entity can detect the target with one or more of the wide sensing signal beams. The network entity can transmit a narrow sensing signal beam in a direction towards the target to track the target, after the target has been detected. The network entity can further increase a power of the narrow sensing signal beam to provide energy to the target.

Abstract: Apparatuses and methods for scrambling of FMCW for interference mitigation in JCS are described. An apparatus is configured to obtain a set of phase-coded FMCW signals that is phase-coded based on a scrambling ID for the first node and/or a second node. The apparatus is configured to descramble the set of phase-coded FMCW signals based on the scrambling ID. The set of phase-coded FMCW signals is descrambled to obtain a set of descrambled FMCW signals. The apparatus is configured to perform sensing, communication, and/or JCS functions based on the set of descrambled FMCW signals. Another apparatus is configured to configure a set of FMCW signals, and to scramble the set of FMCW signals based on a scrambling ID for the first node and/or a second node to obtain a set of phase-coded FMCW signals. The apparatus is configured to transmit, for the second node, the set of phase-coded FMCW signals.

Abstract: Apparatuses and methods for waveform adaptations in RF sensing are described. An apparatus is configured to operate in one of a wireless communications mode or a sensing mode. The wireless communications mode is associated with at least one of a communications or sensing waveform. The sensing mode is associated with at least one of the communications or the sensing waveform, and the sensing and communication waveforms are different. The apparatus is also configured to obtain an indication of a switch to operate in another of the wireless communications or sensing mode. The apparatus is further configured to switch to the other mode per the indication. Another apparatus is configured to operate in the wireless communications or the sensing mode, to provide an indication of a mode switch, and to switch to the other mode per the indication.

Abstract: Certain aspects of the present disclosure provide techniques for allocating channel state information (CSI) processing unit (CPU) for user equipment (UE) initiated CSI. For example, the UE may receive an indication from a network entity (e.g., a base station or gNB) configuring the UE with a number of one or more CPUs allowed to be occupied for UE-initiated CSI feedback. The UE uses the at least one of the CPUs to calculate UE-initiated CSI feedback. The UE transmits at least one report including the UE-initiated CSI feedback if one or more conditions are met, such as when a mismatch between a CSI metric for a scheduled physical downlink shared channel (PDSCH) and a CSI metric calculated as part of the UE-initiated CSI feedback is equal to or exceeding a threshold value.

Abstract: Methods, systems, and devices for power backoff techniques for modulation schemes are described. A user equipment (UE) may receive an indication of a constellation distribution parameter and a modulation scheme to be used by the UE for an uplink message on an uplink channel. The UE may determine an uplink transmission power based at least in part on the indicated constellation distribution parameter and the indicated modulation scheme. The UE may transmit the uplink message using the indicated modulation scheme according to the determined uplink transmission power. In some examples, the UE may transmit a report indicating a power headroom parameter and an output power parameter based at least in part on the constellation distribution parameter.
