Embodiment Construction

[0053] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0054] refer to figure 1 , which shows a flow chart of the steps of Embodiment 1 of a method for controlling a radio frequency antenna switch of the present application, which may specifically include the following steps:

[0055] Step 101, receiving downlink wireless frame data sent by the current subframe or time slot;

[0056] Usually, a base station mainly includes parts such as a baseband unit BBU (BaseBand Unit) and a remote radio frequency unit (RRU) (RemoteRF Unit). The remote radio frequency unit includes an interface part, an intermediate frequency part, a radio frequency part and a power amplifier. Among them, the interface part is the baseband data interface unit between the remote radio fr...

Abstract

The embodiment of the invention provides a radio frequency antenna switch control method and apparatus. The method comprises the following steps: receiving downlink wireless frame data sent by a current sub-frame or time slot; calculating a delay value of the downlink wireless frame data; judging whether the downlink wireless frame data are non-service data; and if so, closing a radio frequency antenna switch according to the delay value. The energy-saving closing area of a base station can be accurately and automatically determined, different link delays among different hardware devices and the data processing delays in single and double modes are compatible, the defect that the delay value needs to be determined by manual debugging in other similar schemes is avoided, the self-adaption is high, no human intervention is required, and the debugging time is shortened.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a control method for a radio frequency antenna switch and a control device for a radio frequency antenna switch. Background technique [0002] Energy saving and emission reduction is a major issue in the development of the world today, and the communication industry is no exception. Among all network devices, the power consumption of base stations accounts for a large proportion. Therefore, reducing the power consumption of base station devices is the top priority for energy saving and emission reduction of network devices. [0003] One of the most effective energy-saving methods for base stations of TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) or TD-LTE (Time Division Long Term Evolution) systems It is to turn off the radio frequency antenna switch under the time slot or subframe with no business data. Under normal circumstances, the ...
