Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] In the embodiment of the present invention, the change of the uplink interference environment caused by the terminal moving or joining and withdrawing is tracked and identified, so as to adapt the resource allocation to the change of the network environment. At the same time, resource allocation is performed according to the degree of uplink interference between terminals to achieve adaptive uplink interference coordination. Th...

Abstract

The embodiment of the invention discloses an up-link interference coordination method and a base station. The up-link interference coordination method comprises the following steps of: obtaining channel condition changing parameters in a cell according to channel information obtained from terminals, wherein the channel condition changing parameters reflect an up-link interference condition between two adjacent sections of the cell; judging whether the channel condition changing parameters in cell exceed preset threshold values; and if so, redistributing the channel resources of the terminals by adopting a coloring algorithm according to an up-link interference degree between two terminals so as to reduce up-link interference between the two adjacent sections. According to the up-link interference coordination method, the unnecessary up-link interference between the two adjacent sections is eliminated, and the purpose of maximizing the throughout of a whole network is achieved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an uplink interference coordination method and a base station. Background technique [0002] Neighboring interference in cellular networks is an important factor restricting the signal quality and user experience of network users (especially cell edge users). Inter-adjacent interference distinguishes between downlink adjacent interference and uplink adjacent interference. For the downlink adjacent cell interference problem, it can be effectively controlled by combining base station coverage control and scheduling algorithms. For the uplink adjacent cell interference problem, due to the lack of an effective and fast terminal power control mechanism, only the adjacent cell coordination is usually performed through the scheduling algorithm. [0003] The existing scheduling algorithm for interference in the uplink field is a scheduling algorithm at the Radio Resource Ma...
