Problems solved by technology

[0002] The current base station power saving scheme generally turns on or off the power amplifier module of the base station RRU according to the business load. Since the RRU needs to transmit information such as cell broadcast and control even when the business load is zero, the power amplifier of the RRU cannot be turned off in these time slots. module, the overall power saving effect is limited

Embodiment Construction

[0056] In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.

[0057] figure 1 It is a schematic flowchart of a power saving method for a base station according to an embodiment of the present invention. The power saving method for a base station in this example is applied to the BBU, as shown in figure 1 As shown, the power saving method of the base station includes the following steps:

[0058] Step 101: For a set interval, set the first and last two baseband processing devices BBU in the interval to be on.

[0059] In the embodiment of the present invention, the set interval can be set by the base station management personnel. In...

Abstract

The invention discloses a base station power saving method, a base band unit (BBU) and a remote radio unit (RRU). The method comprises the steps of for a set section, setting the two base band units at the head and tail of the section to be in an open state; detecting movement information of a target by the BBU in the open state via the RRU connected with the BBU; when the movement information of the target indicates that the target moves to a cell in which the BBU in the open state is located from a first direction, instructing the BBU close to the BBU in the open state to open the RRU connected with the previous BBU; and when the movement information of the target indicates that the target moves away from the cell in which the BBU in the open state is located from a second direction, and the BBU in the open state is not the head / tail BBU, closing the BBU in the open state.

Description

technical field [0001] The present invention relates to a power saving technology in a base station, in particular to a power saving method for a base station, a base band processing device (BBU, Base Band Unit) and a radio remote device (RRU, Radio Remote Unit). Background technique [0002] The current base station power saving scheme generally turns on or off the power amplifier module of the base station RRU according to the business load. Since the RRU needs to transmit information such as cell broadcast and control even when the business load is zero, the power amplifier of the RRU cannot be turned off in these time slots. module, the overall power saving effect is limited. Taking Time Division-Long Term Evolution (TD-LTE, Time Division-Long Term Evolution) as an example, different symbols in each time slot of a radio frame carry control information and user service information respectively, and when there is no user service, the symbols carrying user service informati...
