Embodiment 1

[0055] Embodiment 1. Distributed adjustment

[0056] In the distribution adjustment mode, various calculations are performed simultaneously on each member base station of the community. After the calculation is completed, all base stations jump to the target resource individual calculated by themselves.

[0057] When distributed adjustment is adopted, each base station in the community needs to store the adjacency table of the community. The adjacency table records the adjacency relationship of each base station in the community, indicating whether two base stations are neighbors to each other.

[0058] When the topology of the community changes, the base station at the changed position can directly know the change and its time point, and then these base stations broadcast to other base stations through the wired network; or the base station at the changed position will know the change and its time point, broadcast to their respective neighboring stations, and then these neig...

Embodiment 2

[0067] Embodiment 2, centralized adjustment

[0068] In the centralized adjustment mode, a base station or server stores and maintains the adjacency table of the community. For convenience of description, the base station or server is referred to as the master station, and other base stations are referred to as slave stations. For example, but not limited to, the first activated base station in the community is the master station, the base station with the most neighbor stations in the adjacency table is the master station, and other base stations are slave stations. The adjacency table records the adjacency relationship of each base station in the community, indicating whether two base stations are neighbors to each other.

[0069] As shown in Figure 6, it specifically includes the following processes:

[0070] First of all, when the community topology changes, a new community is generated, and the master station needs to know the change. Because when the community changes...

Abstract

The method comprises: when the community topology structure changes such as there is a new base station adding or quitting, and the community goes to be combined or separated, each base station uses a unified algorithm to re-allocate channel resources or allows one of the base stations in the community to allocate communication resources, and then according to re-allocated resources each base station is adjusted to its available resources on an unified time point. The communication resources thereof comprise time slice, CDMA code word and sub-channel as well as frequency spectrum.

Description

technical field [0001] The invention relates to communication technology, in particular to a method for adjusting communication resources in a community of base 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. At the same time, wireless spectrum resources are very precious, especially in unplanned areas or unlicensed frequency bands (LE Band, License-Exempt Band), which often require multiple base stations to operate on the same channel, resulting in interfere with each other. In order to coordinate the coexistence of devices in the same frequency band, especially the coexistence of devices in the license-free frequency band, or devices that have not undergone network frequency planning, it is necessary to establish some coexistence mechanisms between devices. [0003] The neighbor st...
