Abstract: Certain aspects of the present disclosure provide techniques for sharing machine learning models and an indication of transmission and reception points (TRPs) for which the machine learning models are applicable between wireless nodes such as user equipments (UEs) and base stations (BSs). For example, a UE receives an indication of one or more machine learning models associated with at least one TRP of one or more TRPs from a BS. The UE then uses the at least one of the one or more machine learning models for applications related to the at least one TRP. The applications may include a channel state information (CSI) compression, a cross frequency channel prediction, and a beam selection.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, from a base station, a common downlink control information (DCI) message indicating an update to a common beam which applies to a set of UEs, where for each UE of the set of UEs the common beam is shared across a set of channels, a set of reference signals, or both. The UE may receive, via the common DCI message, an indication of the set of UEs associated with the update to the common beam. The UE may then perform at least one beam switching procedure to update the common beam at the UE based on receiving the common DCI message and the UE being included within the set of UEs.

Abstract: A method of wireless communication by a user equipment (UE) includes generating, by an upper analog media access control (MAC-A) layer of a protocol stack, a data packet with a header and a data field. The header indicates a neural network identifier (ID) and a request ID. The data field includes gradient data for a federated learning iteration. The method also includes transferring the data packet to lower layers of the protocol stack for transmission to a network device across a wireless network.

Abstract: Methods, systems, and devices for wireless communications are described. The method may involve a receiving device selecting a receive beam for receiving a signal from a transmitting device based on a relative direction of the transmit beam used to transmit the signal. A first wireless device may receive, from a second wireless device, an indication of a first angular range. The first angular range may be associated with a set of transmit beams for the second wireless device and correspond to at least two transmit beams of the set of transmit beams. The first wireless device may select a receive beam from a set of receive beams based on the first angular range and receive a reference signal, from the second wireless device, using the selected receive beam. The first device may also transmit channel information, to second wireless device, based on the reference signal.

Abstract: A user equipment may be configured to perform UE indication to temporarily suspend report occasions. In some aspects, the user equipment may receive report configuration information from a base station, the report configuration information identifying a report parameter to provide in a channel state information (CSI) report, and determine a predicted value of the report parameter based on a plurality of historic measurements. Further, the user equipment may determine to suspend transmission of the report parameter based on the predicted value, and transmit a report suspension message to the base station, the report suspension message indicating that the UE has implemented a temporary suspension of reporting of the report parameter in the CSI report.

Abstract: A method of wireless communication by a user equipment (UE) receives a machine learning model from a base station. The UE reports, to the base station, a machine learning processing capability. The UE also transmits, to the base station, gradient updates or weight updates to the machine learning model. A base station transmits a machine learning model to a number of UEs. The base station receives, from each of the number of UEs, a machine learning processing capability report. The base station groups a number of UEs in accordance with the machine learning processing capability reports, to receive gradient updates to the machine learning model.

Abstract: A method of wireless communication by a user equipment (UE) includes receiving an uplink grant from a network device. The method also includes determining, by a lower analog media access control (MAC-A) layer of an analog data communications stack, a quantity of analog neural network gradients to transmit in a data packet using resources allocated by the uplink grant. The determining is based on an analog physical (PHY-A) layer encoding scheme and the resources allocated by the uplink grant. The method further includes segmenting the analog neural network gradients into the data packet. The method still further includes transferring the data packet to the PHY-A layer for transmission to the network device across a wireless network.
