Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a client device may determine a feedback associated with a machine learning component based at least in part on applying the machine learning component. Accordingly, the client device may transmit a quantized value based at least in part on the feedback. The quantized value is determined using randomization with probabilities based at least in part on respective distances between one or more values of the feedback and a plurality of quantized digits. Numerous other aspects are provided.

Abstract: A base station may precode a first reference signal using a first precoder (P1) and at least one second reference signal using at least one second precoder (P2). At least two UEs may measure the first reference signal and the at least one second reference signal, and transmit channel state feedback based on the measuring (m11 and m12 for a first UE, and m21 and m22 for a second UE). The channel state feedback may comprise channel state information compressed by at least one neural network. The base station may derive a higher-level precoder (W) for multiple-input multiple-output (MIMO) downlink transmission to the at least two UEs.

Abstract: A communications transceiver system that employs self-interference mitigation techniques can detect static objects by using techniques that introduce angular or Doppler diversity. This can include moving Tx and Rx antennas and/or performing beam sweeping. When processing RF sensing data from reflected RF signals, self-interference mitigation techniques can be used and compensation can be made for the movement and/or beam sweeping to allow for both self-interference mitigation and detection of static objects.

Abstract: A method, apparatus, or computer-readable medium with instructions for beam management for radio frequency (RF) sensing at a wireless device. The wireless device performs a first beamsweep of an RF signal and measures a reflection of the RF signal based on the first beamsweep. The wireless device performs a second beamsweep of the RF signal, wherein the first beamsweep is based on a different parameter than the second beamsweep and measures the reflection of the RF signal based on the second beamsweep. The wireless device selects a beam for RF sensing based on the first beamsweep and the second beamsweep.

Abstract: A method of wireless communication performed by a first transmission and reception point (TRP), includes receiving a message indicating a measurement of a reference signal (RS) transmitted in a first band to a wireless device or one or more features of a second band estimated by the wireless device. The first TRP may operate in the second band not overlapping the first band, the one or more features comprise one or more of a channel characteristic, a signal strength, or a beam direction of the second band. The method also includes adjusting one or more parameters of the second band in response to receiving the message. The one or more parameters may include one or both of a channel or a beam direction. The method further includes transmitting signals to a user equipment (UE) in the second band according to the one or more adjusted parameters.
