Abstract: Aspects of the present disclosure describe receiving, from an access point, an indication of at least one of a beamforming method for beamforming a RS or a normalization method for normalizing power for beamforming the RS. A channel covariance matrix corresponding to interference over a plurality of antenna ports can be generated, as well as a RS beamforming matrix based at least in part on modifying the channel covariance matrix and on the normalization method. The RS can be generated based on the RS beamforming matrix and the beamforming method. The RS can be transmitted to the access point based on the RS beamforming matrix.

Abstract: Disclosed are techniques for receive beam selection for measuring a reference radio frequency (RF) signal. In an aspect, a first node determines a type of measurement to be performed on the reference RF signal, selects a receive beam based on the type of measurement to be performed on the reference RF signal, generates the selected receive beam, receives, from a second node, using the generated receive beam, the reference RF signal transmitted on a wireless channel, and performs one or more measurements on the received reference RF signal according to the type of the measurement to be performed.

Abstract: A network entity may transmit a configuration for neural network training parameters for wireless communication by the UE, and the UE may train the neural network at the UE based on the configuration received from the network entity. The network entity may transmit a training command in a wireless message to the UE, and the UE may train the neural network based on the received configuration in response to the received training command. The configuration may include a period of time associated with the training the neural network. The period of time may indicate an action for the UE to perform when the period of time expires, and/or indicate the periodicity of the neural network training.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for reporting configurations for neural network-based processing at a UE. A network entity may transmit to the UE a CSI configuration that includes one or more parameters for a neural network and one or more reference signals. The UE may measure the one or more reference signals based on the CSI configuration. A CSI may be based on the one or more parameters and the measurement of the one or more reference signals. The UE may report the CSI to the network entity based on output of the neural network.

Abstract: This disclosure provides methods, devices and systems for channel sounding for wireless communications. Some implementations more specifically relate to scheduling sounding reference signal (SRS) resource sets for wireless devices having more than 4 receive (RX) antenna ports. In some implementations, a base station may determine an antenna switching capability of a user equipment (UE). The antenna switching capability indicates a number of RX antenna ports of the UE. The base station schedules a number of SRS resource sets for the UE based at least in part on the number of RX antenna ports in excess of four. For example, the number of RX antenna ports may be equal to 8. As another example, the number of RX antenna ports may be equal to 6. The base station further receives, from the UE, uplink transmissions of one or more SRS resources for each of the scheduled SRS resource sets.
