The described technology is generally directed towards accelerating distributed principal components in the presence of noisy channels. A federated training based method is disclosed. The method can calculate a desired common subspace for edge devices under the coordination of a server. The server can be connected to the edge devices via noisy wireless channels. A broadband communication system can be used, wherein devices can transmit local gradients by linear analog modulation over sub-channels in communication rounds for over-the-air aggregation. Before each communication round, the server can detect information of a current region. Based on the region information, an online region-adaptive power control scheme can be applied to accelerate the process.

Apparatuses, methods, and systems are disclosed for determining a power offset parameter. One method (500) includes determining (502) a power vector using at least one sounding reference signal resource. The power vector includes a power corresponding to each port of a device. The method (500) includes determining (504) a power offset parameter based on the power vector, and transmitting (506) the power offset parameter.

A method of a user equipment (UE) for an uplink power control is provided. The method comprises receiving, from a base station (BS), configuration information indicating a power scaling value (β) to be applied to a physical uplink shared channel (PUSCH) transmission, determining, based on the received configuration information, the power scaling value (β) for the PUSCH transmission from values of $\beta =1\mathrm{or}\beta =\frac{{\rho }_0}{\rho },$
where ρ.sub.0 is a number of antenna ports with a non-zero PUSCH transmission power and ρ is a number of sounding reference signal (SRS) ports, and transmitting the PUSCH transmission with a linear value ({circumflex over (P)}) of transmit power scaled based on the determined power scaling value (β), where the linear value ({circumflex over (P)}) of the transmit power after power scaling, β×{circumflex over (P)}, is divided equally across the antenna ports on which the UE transmits the PUSCH transmission with non-zero power.

Provided are a method for a terminal for carrying out uplink communication in a wireless communication system, and an apparatus using the method. The method receives an uplink communication-related parameter independently configured for each analog beam, and carries out the uplink communication on the basis of the parameter. If the uplink communication is carried out using a particular analog beam, then an uplink communication-related parameter configured on the particular analog beam is applied to the uplink communication.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source UE, a first sidelink communication. The UE may generate a transmit power control command based at least in part on a signal to interference noise ratio measurement associated with the first sidelink communication. The UE may transmit, to control a transmit power for a second sidelink communication, the transmit power control command to the source UE. Numerous other aspects are provided.
