Embodiment Construction

[0056] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0057] In the present invention, the base station requires the terminals belonging to the system to monitor the coexistence messages broadcast by the base station. When abnormal energy is detected during the time period when the transmission energy should be turned off, the terminal will receive the message through certain means, such as CSI backoff. The broadcast message from the neighboring station in this CSI time slot partially solves the above-mentioned problems caused by the merger of the communities.

[0058] refer to Figure 5 to Figure 8 , to illustrate the neighbor station interference detection and identification method according to the present invention.

[0059] like Figure 5 As shown, the neighbor station interference detection method according to the present invention includes the following steps: S501, the base ...

Abstract

The present invention discloses a method for detecting interference between neighboring stations comprising the following steps that a base station informs the terminal of a radio receiving system of coexistent signal time slot information; the terminal obtains the silent time slot based on the coexistent signal time slot information and monitors the interference information of neighboring station in the silent time slot; the terminal reports the monitored interference information to the base station. The present invention also provides a detection device for detecting the interference of neighboring station, a method and a device which are used for identifying the interfering neighboring station. With the present invention, the problem that two base stations which are not adjacent become the neighboring stations and cause the source conflict caused by the changes of terminal states or terminal positions and the changes of environment is solved.

Description

technical field [0001] The present invention relates to the field of communications, in particular, to the detection and identification of adjacent station interference, and more specifically, to a method for detecting interference with adjacent stations, a device for detecting interference with adjacent stations, and a method and device for identifying interference with adjacent stations . Background technique [0002] Broadband wireless access technology is currently developing vigorously, and the technology of using wireless resources to carry out broadband metropolitan access has strong vitality and market space. [0003] At the same time, wireless spectrum resources are very precious, especially in areas that are not well planned or in unlicensed frequency bands, there are often multiple base stations (BS, Base station) operating on the same channel, resulting in mutual interference between the systems they belong to. . In order to coordinate the coexistence of device...
