Abstract

The invention discloses a power control device, method and electronic equipment. The power control device includes: a signal receiving path; an uplink listening reference signal SRS transmitting path; A radio frequency transceiver; a processor connected to the radio frequency transceiver, the processor obtains the difference between the first loss of the signal receiving path and the second loss of the SRS transmission path, and adjusts according to the difference The transmission power of the uplink sensing reference signal SRS in the SRS transmission path. In the embodiment of the present invention, the processor adjusts the transmission power of the SRS signal according to the difference between the first loss on the signal receiving path and the second loss on the SRS transmission path, so that the power of the SRS signal received by the base station can better match the corresponding The loss of the signal receiving path, thereby increasing the downlink data rate.

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...
