This disclosure provides a sidelink power control method and a terminal device. The method is applied to the terminal device, and includes: sending information to a first terminal device in sidelink communication, so that the first terminal device generates power control indication information based on a receiving status of the information; receiving the power control indication information from the first terminal device; and determining an information transmit power of the terminal device in the sidelink communication according to the power control indication information.

A method, a terminal device, and a base station for power control in random access procedure. The method implemented at a terminal device includes: obtaining at least one power control parameter to be used for a request message for a random access; and transmitting, to a base station, the request message for the random access. A power of the request message for the random access is controlled based on the at least one power control parameter. The request message comprises: a random access channel (RACH) preamble and a physical uplink shared channel (PUSCH). The power control may be achieved in a RACH procedure different with 4-step RACH procedure, such as in a 2-step RACH procedure.

A method for avoiding false alarms of Channel State Information (CSI) due to the activation of a Closed Loop Power Control (CLPC) function is provided. The method is executed by a transmitting device and includes: determining whether the CLPC function of the transmitting device is enabled; adding at least one CLPC tag to a physical layer convergence procedure (PLCP) protocol data unit (PPDU) when the CLPC function is enabled; and transmitting the PPDU.

5G and especially 6G are intended to accommodate high-speed mobile user devices and access points such as wireless devices on trains and airplanes, while retaining enhanced mobile broadband eMBB service. Therefore, new resource-efficient, low-complexity procedures are needed for measuring and correcting the Doppler frequency shift. To assist user devices, a base station or access point can periodically broadcast a current geographical location of the base station or access point in a localization message. In some embodiments, the geographical location data can be included in a periodically broadcast system information message, such as unused space of a SSB (synchronization signal block) message or an SIB1 (first system information block) message. User devices can then determine a vector toward the base station or access point relative to the user device location and velocity, and thereby calculate a Doppler correction without a frequency scan or other overhead, according to some embodiments.
