Abstract

A signal transmission method, related equipment and system, the method comprising: a terminal receives configuration information, the configuration information indicates N sets of power control parameters configured for M uplink signal resources or a set of uplink signal resources; M≥1, M is positive Integer, N>1, N is a positive integer; the terminal transmits an uplink signal on the M uplink signal resources or a set of uplink signal resources, and transmits an uplink signal on the M uplink signal resources or a set of uplink signal resources The power is determined according to a first power control parameter; the first power control parameter is selected from the N sets of power control parameters. The above solution can realize more flexible adjustment of the uplink transmission power, and can realize the maximization of the power efficiency of the uplink transmission and the performance of the uplink transmission.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a signal transmission method, related equipment and system. Background technique [0002] As one of the key technologies of the new generation of wireless access technology (new radio access technology, NR), high frequency (high frequency, HF) can provide more spectrum resources, support more antennas, and improve system capacity. Research extensively. As the frequency increases, the wavelength of the wireless signal becomes shorter accordingly. The short wavelength can greatly reduce the size of the antennas at both ends of the transceiver, so multiple antennas can be easily integrated into a panel with limited space. Through the multi-antenna beam property technology, the energy of the transmitted signal is concentrated in a certain direction for transmission, which can effectively improve coverage and improve communication performance. Correspond...
