Problems solved by technology
In TD-SCDMA (Time Division-Synchronization Code Division Multiple Access, Time Division Synchronization Code Division Multiple Access system), the obtained downlink power is only the power of DwPTS, and the power of DwPTS is fixed after the cell is established, and will not change It changes with the change of business volume, so it is relatively one-sided, and cannot reflect the power of the entire subframe, let alone the real downlink power of the air interface
[0006] Whether using the downlink power detection scheme of scheme 1 or scheme 2, or other existing schemes, they only reflect the downlink power of the RRU air interface one-sidedly, but cannot fully and truly reflect the downlink power of the RRU air interface

Embodiments of the invention disclose a remote radio unit (RRU) downlink power detection method and device. A RRU has channels used for carrying out radio communication. The method comprises steps of obtaining the downlink power of each channel; using the downlink power of each channel to obtain the average downlink power of each channel; obtaining the link real-time gain of the RRU; and using the average downlink power of each channel and the link real-time gain to obtain the downlink power of the RRU. The embodiments are used for comprehensively and truly reflecting the downlink power of equipment.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for detecting downlink power of a remote radio unit RRU and a device for detecting downlink power of a remote radio unit RRU. Background technique [0002] With the increasing awareness of energy saving and emission reduction in all aspects of people's lives, people are paying more and more attention to the energy consumption of equipment. By counting the downlink power of the device, the user can know the operation status of the RRU (Remote Radio Unit, remote radio unit), so that the user can adjust the device configuration parameters in time to solve potential problems. [0003] Devices in a wireless communication system communicate using radio frames. refer to figure 1 A schematic diagram of a wireless frame structure is shown, the wireless frame is composed of two half-frames with a length of 5ms, and each half-frame is composed of five subfr...
