Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive a message indicating geographic location information related to beamforming an air-to-air sidelink message via a sidelink channel. In some examples, a second UE may transmit the message or different as a message scheduling the sidelink message. The geographic directions to avoid when beamforming the sidelink message, or a combination thereof. The first UE may identify one or more precoding parameters based on the geographic location information. The first UE may transmit the air-to-air sidelink message to the second UE. The sidelink message may be precoded for transmission via a transmission beam using the one or more precoding parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A first device (e.g., a base station) may transmit reference signals to a second device (e.g., a user equipment (UE)) via transmitter antenna circles. The second device may receive and measure the reference signals via corresponding receiver antenna circles. Both the transmitter antenna circles and the in receiver antenna circles may include a center antenna circle and one or more peripheral antenna circles. The second device may transmit channel gain measurements to the first device based on measuring the reference signals. The first device may determine orbital angular momentum (OAM) modes, a power loading scheme, or both for the transmitter antenna circles based on the channel gain measurements. The first device may transmit OAM transmissions to the second device based on the determined OAM modes, the power loading scheme, or both. The OAM transmissions may have different OAM states, polarizations, or both.

Abstract: Wireless communication systems and methods related to multiplexing of uplink control information (UCI) and configured grant-UCI (CG-UCI) of different priorities are provided. A user equipment (UE) determines that a physical uplink control channel (PUCCH) resource at least partially overlaps with a configured grant physical uplink shared channel (CG-PUSCH) resource, where the PUCCH resource and the CG-PUSCH resource are associated with different priorities. The UE, based on a threshold number of bits, a number of bits of a low-priority uplink control information (UCI) for multiplexing with at least one of a high-priority CG-PUSCH transmission, a low-priority CG-PUSCH transmission, or a high-priority UCI. The UE multiplexes the number of bits of the low-priority UCI with the at least one of the high-priority CG-PUSCH transmission, the low-priority CG-PUSCH transmission, or the high-priority UCI to generate a multiplexed uplink transmission, and transmits the multiplexed uplink transmission in the PUCCH resource or the CG-PUSCH resource.

Abstract: A method performed by a user equipment (UE) generates local gradients for a federated learning task. The method calculates a gradient Sum-Power level based on the local gradients. The method receives a mapping between gradient Sum-Power levels and scaling factors for channel inversion coefficients to process a data block into an unencoded uplink signal. The method also determines a channel inversion coefficient based on a scaling factor obtained from the mapping and the calculated gradient Sum-Power level. The method applies analog modulation and the channel inversion coefficient to the data block to form the unencoded uplink signal. The method further transmits, to a network, the unencoded uplink signal on shared uplink resources for an over-the-air computation of global gradients for the federated learning task.
