Method and device for performing signal transmission

Abstract

The invention relates to the technical field of wireless communication, and particularly relates to a method and a device for performing signal transmission and aims at solving a problem of relatively high channel interference in the prior art. The method of the embodiment of the invention comprises that: all access points APs in a coverage area of a wireless local area network WLAN are grouped, wherein the APs in the same group after grouping can mutually acquire signal transmitting state, a perception area of each AP completely comprises the effective coverage area of other APs in the same group, and the APs which are arranged in different groups with the same allocated channel cannot mutually acquire the signal transmitting state and the perception areas are not overlapped. With adoption of the method and the device of the embodiment of the invention, the APs in the same group can share capacity of the same channel so that interference is avoided, the APs which are arranged in different groups with the same allocated channel cannot mutually acquire the signal transmitting state and the perception areas are not overlapped, and thus the APs of different groups respectively use the channels independently and generation of high interference is avoided.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and equipment for signal transmission. Background technique [0002] The working frequency band of Wireless Local Area Networks (WLAN) 2.4GHz is 2.4GHz~2.4835GHz. Usually, this frequency band is divided into 13 channels, respectively 1~13. The frequencies contained in these 13 channels overlap Yes, there are only three channels that do not overlap with each other and can be used at the same time, such as the commonly used channels 1, 6, and 11. When multiple access points (Access Points, APs) are required for some ultra-large-scale WLAN coverage areas, in order to minimize signal overlap and interference between channels, adjacent APs should avoid using the same channel. In the prior art solution, the three channels are allocated as staggered as possible, and the AP uses different channels alternately, so that the signals in the overlapping area are not i...
