Abstract: Aspects described herein relate to signals transmitted in federated learning (FL) of a neural network (NN) using wireless communications. A transmitting device can generate an analog modulation signal to indicate an updated value for one or more coefficients for a federated learning (FL) procedure for a neural network, and the transmitting device can transmit the analog modulation signal over time and frequency resources configured for a UE group of multiple UE groups, where each UE group of the multiple UE groups is associated with a range of values of a measured signal metric. The receiving device can receive a combined signal from one or more UE groups and can normalize the received signal by power to determine the combined coefficient update for the NN.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects relate to polar encoding and decoding of communications. Aspects described herein provide techniques by which two forms of polar encoding, bit-interleaved coded modulation (BICM) and multi-level coding (MLC) can be implemented using the same transmit procedure and hardware.

Abstract: Methods, systems, and devices for wireless communications are described. Polar coding involves assigning bits to different bit-channels, and encoding the bits such that certain bit-channels (e.g., polar channels) are polarized to increased reliability, while other bit-channels are polarized to decreased reliability. To ensure that polar codes for extended reality (XR) and video applications have increased reliability for the aspects of an XR stream or video code that are most important, the information bits of a stream may be sorted based on priority or importance. Then the sorted information bits may be mapped to the most reliable bit-channels of a polar encoder. Any errors in the transmission may therefore be most likely to occur in the less important bits. Accordingly, in the case of XR, the information bits that are most important to user experience/perception are the most likely to be successfully received and decoded at the receiver.
