Abstract: A parameter server located at a base station may coordinate federated learning among multiple user equipment (UEs) using over-the-air (OTA) aggregation with power control to mitigate aggregation distortion due to amplitude misalignment. The parameter server may select a first group of UEs for a first OTA aggregation session of a federated learning round based on a common received power property of each UE in the first group of UEs. The parameter server may transmit a global model to the first group of UEs. Each UE in the first group may train the global model based on a local dataset and transmit values associated with the trained local model. The parameter server may receive, on resource elements for the first group of UEs, a first aggregate amplitude modulated analog signal representing a combined response from the first group of UEs.

Abstract: A user equipment (UE) may receive a set of reference signals (RSs) from each of a plurality of network nodes. The set of RSs may include a first subset of RSs from a first network node of the plurality of network nodes and a second subset of RSs from a second network node of the plurality of network nodes. The first subset of RSs and the second subset of RSs may be non-orthogonal relative to one another and may be received during a same time period. The UE may measure the set of RSs from each of the plurality of network nodes received during the same time period. The UE may transmit, for a network entity, positioning information associated with measuring the set of RSs from each of the plurality of network nodes.

Abstract: Aspects presented herein may enable a network entity to calculate a relative clock drift between a Tx antenna panel and an Rx antenna panel that use different RF hardware/circuits (e.g., clocks). In one aspect, a network entity obtains a plurality of RTT measurements between a Tx antenna panel, a device with a known position, and an Rx antenna panel over a period of time, where the Tx antenna panel is associated with a first clock and the Rx antenna panel is associated with a second clock. The network entity obtains a first timing delay associated with the device based on the plurality of RTT measurements. The network entity calculates a clock offset between the Tx antenna panel and the Rx antenna panel based on the obtained first timing delay associated with the device.
