Embodiment Construction

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

[0054] refer to figure 1 , shows a flow chart of the steps of Embodiment 1 of a remote interference adaptive method of the present invention, the method is applied to an air interface system, where the air interface (New Radio, NR) system may include several base stations, The method may specifically include the following steps:

[0055] Step 101, the local base station obtains the interference power of the symbol of the uplink time slot, and judges whether the interference power is greater than a preset first threshold value;

[0056] In the NR system, it can be composed of several base stations. For the local base station deployed locally, when the downlink time slot symbol of the remote base station is transmitted over a long di...

Abstract

The embodiment of the invention provides a far-end interference self-adaption method and a far-end interference self-adaption device, which are applied tp an air interface system. The air interface system comprises a local base station and a far-end base station. The method comprises the steps of acquiring interference power of an uplink time slot symbol through a local base station; judging whether the interference power is greater than a preset first threshold value or not; when the interference power is greater than a preset first threshold value, enabling the local base station to determine a plurality of first target symbols corresponding to the interference power in the uplink time slot symbols, then, enabling the local base station to adjust the plurality of first target symbols; and sending a characteristic sequence for the interference power to the far-end base station, and enabling the far-end base station to adjust a downlink time slot symbol of the far-end base station according to the characteristic sequence. Therefore, scheduling of downlink time slot symbol services close to the GP and scheduling of uplink time slot symbols subjected to severe interference are adaptively carried out in real time, uplink services are prevented from being blocked by base stations due to far-end interference, and key technical indexes and user experience of the base stations subjected to far-end interference are guaranteed.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an adaptive method for far-end interference and an adaptive device for far-end interference. Background technique [0002] With the development of the fifth-generation wireless communication technology, 5G will be able to provide users and applications with access to information and data sharing anytime, anywhere, connect all content wirelessly, and provide fast and rich content and services, thereby enriching the people's lives. [0003] For the uplink and downlink time slots of the NR (New Radio, new air interface) system, the same frequency resource can be shared through the time division mode. However, in a specific climate or geographical environment, the downlink time slot data of the local base station of the NR system is transmitted over a long distance, and when it exceeds the GP (Guard Period, guard interval), it is easy to interfere with the uplink time...
