Abstract: A method for wireless communication by a user equipment (UE), includes receiving, from a base station, a reference signal (RS) on a set of resource elements (REs), the RS having been multiplexed onto the set of REs based on a non-orthogonal cover code, and a number of REs in the set of REs being less than a number of ports associated with the RS. The method further includes estimating, at the UE via a channel estimation neural network, a channel based on receiving the RS. The method still further includes transmitting, to the base station, a feedback report associated with the estimated channel based on receiving the RS.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a wireless communications system may support machine learning and may configure a user equipment (UE) for machine learning. The UE may transmit, to a base station, a request message that includes an indication of a machine learning model or a neural network function based at least in part on a trigger event. In response to the request message, the base station may transmit a machine learning model, a set of parameters corresponding to the machine learning model, or a configuration corresponding to a neural network function and may transmit an activation message to the UE to implement the machine learning model and the neural network function.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first indication of a first number of antenna ports for which the UE is to report channel state information (CSI), and a second indication of a second number of antenna ports on which the UE is to measure CSI reference signals (CSI-RSs). The second number may be less than the first number. The UE may receive an indication of one or more antenna port parameters, where each may be associated with one of the first number of antenna ports or the second number of antenna ports. The UE may determine the CSI for the first number of antenna ports using the one or more antenna port parameters and measurements made by the UE on the second number of ports, and may transmit a report including the CSI for the first number of ports.

Abstract: An OAM core network may receive a request for a ML/NN model and features associated with a ML/NN procedure. The OAM core network may determine a latest update to the ML/NN model and features based on the request and generate a response to the request indicative of the latest update to the ML/NN model and features. In aspects, a base station may initiate the request for the ML/NN model and features by transmitting the request for the ML/NN model and features to the OAM core network. The base station may receive the generated response of the OAM core network based on the transmitted request. In further aspects, a UE may initiate the request for the ML/NN model and features by transmitting the request to the base station, where the UE may receive the ML/NN model and features from the base station based on the transmitted request.

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.
