Method, device and system for controlling power

Abstract

Embodiments of the present invention relate to the field of communications, and provide apparatus which can improve performance of power control on a user who accesses a signal processing entity not supporting a real-time power control function. The apparatus includes: receiving a first signal sent by a first user who accesses a signal processing entity not supporting the real-time power control function; receiving an instruction which is for processing a control channel signal and is sent by a control apparatus, and setting up a channel for bearing the control channel signal of the first signal; and processing the control channel signal which is of the first signal and is borne by the channel, and generating a detection result of the control channel signal which is of the first signal and is borne by the channel. The embodiments of the present invention are applied for real-time power control on the user.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to a power control method, device and system. Background technique [0002] In a mobile communication system, due to the time-varying nature of air interface channel fading, the inner loop power control (inner loop power control) function of the signal processing entity adjusts the transmit power of the transmitting end in real time according to the signal-to-noise ratio of the signal at the receiving end, thereby ensuring that the receiving end The signal-to-noise ratio of the signal is stabilized at the set level to achieve the purpose of resisting channel fading and improving the demodulation performance of the receiving end. For the signal processing entities in the current system, different signal processing entities independently complete the inner-loop power control function of user signals connected to the entity, so as to compensate the influence of channel fading on user s...

Problems solved by technology

[0003] However, in the existing technology, the inventors found that due to the limitation of user processing resources at the receiving end or the constraints of processing load balance, the detection of different user signals in the system may be completed in different signal processing entities; in addition, due to the different signal processing entities Configuration or constraints between entities (such as: entities need to enjoy the gain of a certain function, etc.), some signal processing entities may not support real-time power control functions, resulting in an inner loop of user signals connected to the signal processing entity Power control cannot compensate for the loss of air interface channel fading by adjusting the transmit power of the sender in real time, which degrades the performance of power control
