    Abstract: Wireless communications systems and methods related to sidelink communication between user equipments (UEs). A first UE determines a power level for a physical sidelink format indicator channel (PSFCH) with multiple interlaced resource blocks (RBs) and/or a common interlace. If a reference power level is provided by a network device such as a base station, the UE may determine power levels based on the reference power level. The UE may also determine power levels based on maximum supported power levels for the UE. In some embodiments, a common interlace uses a fixed percentage of maximum UE power. In other embodiments, available transmit power is evenly split between PSFCH RBs and a common interlace. Priority PSFCH dropping rules may be implemented when scheduled PSFCHs exceed power limitations.

    Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. Various aspects relate to initial physical random access channel (PRACH) power control using multiple PRACH signals, and more particularly to supporting one or more initialization and power control operations between a user equipment (UE) and a network entity prior to an association process. The initial PRACH power control may include the UE transmitting, to the network entity, a first set of PRACH signals at different respective power levels. The network entity may transmit a response message indicating a single set of PRACH signals detected by the network entity, and the UE may detect whether a first PRACH signal, of the first set of PRACH signals, is included in the single set of PRACH signals to select a power level associated with the first PRACH signal for transmitting association messages.

    Abstract: In the present specification, provided are an apparatus and a method for obtaining gradient information, performed by a terminal, in a wireless communication system, wherein the terminal transmits a random access (RA) preamble to a base station, receives a random access response (RAR) from the base station in response to the RA preamble, performs a radio resource control (RRC) connection procedure with the base station, establishes a digital transmission link on the basis of the RRC connection procedure with the base station, and establishes an airComp link that is a link for federated learning with the base station, wherein the terminal acquires the gradient information corresponding to data, and the terminal obtains first information and second information from the gradient information on the basis of data splitting modulation, wherein the first information is information having a lower priority among the information obtained on the basis of the gradient information, the second information is information having a high priority among the information obtained on the basis of the gradient information, the terminal transmits the first information to the base station on a first area, and the terminal transmits the second information to the base station on a second area, wherein the first area is an area distinct from the second area in terms of a frequency domain and a time domain, the first area is a resource area used on the airComp link, and the second region is a resource area used on a digital transmission link.
