Abstract

The invention discloses a power control device and method, and electronic equipment. The power control device comprises a signal receiving path; an uplink sounding reference signal (SRS) transmittingpath; a radio frequency transceiver connected with the SRS transmitting path and the signal receiving path; and a processor which is connected with the radio frequency transceiver, acquires a difference value between the first loss of the signal receiving path and the second loss of the SRS transmitting path, and adjusts the transmitting power of the uplink sounding reference signal SRS in the SRStransmitting path according to the difference value. According to the embodiment of the invention, the processor adjusts the transmitting power of the SRS signal according to the difference between the first loss on the signal receiving path and the second loss of the SRS transmitting path, so that the power of the SRS signal received by the base station can be better matched with the loss corresponding to the signal receiving path, and the downlink data rate is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a power control device, method and electronic equipment. Background technique [0002] In electronic equipment, the radio frequency architecture supports the uplink listening reference signal (Sounding Reference Signal, SRS) transmission, wherein the transmission path of the SRS signal is: transmission filter-SRS switch-switch; the receiving path of the SRS signal is: Toggle Switch - Coexistence Device - Receive Filter. Different devices, as well as interconnection lines between devices, form different signal paths, and different signal paths bring different path losses. Therefore, the channel characteristics (including signal strength and phase) obtained by the base station according to the SRS transmitted signal characteristics), and the channel characteristics of the receiving channel of the electronic device will have errors, which will affect the downlink data...
