Problems solved by technology

[0004] At the same time, the increasingly dense base station deployment also makes the network topology more complex, and the interference between cells has become a major factor limiting the improvement of system capacity, which greatly reduces the spectrum utilization.

Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application. The relevant directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship between the components in a certain posture (as shown in the drawings). Sports conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0048] As mentioned in the background technology, with the further reduction of cell coverage, cell splitt...

Abstract

The invention discloses a micro-cell half-clustering interference coordination method taking user equipment as a center. The method comprises the following steps: acquiring interference information borne by the user equipment to which a base station belongs; classifying the user equipment and the base station based on the obtained interference information of the user equipment to which the base station belongs; clustering the user equipment by using a semi-clustering strategy according to the classification results of the base station and the user equipment; performing resource allocation on the user equipment in each cluster; and when the resource allocation of the user equipment in each cluster is finished, updating the interference information of each piece of user equipment until the total rate of the whole communication system reaches a stable state. According to the scheme, the resource allocation efficiency in the ultra-dense network can be improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a micro cell semi-cluster interference coordination method centered on user equipment. Background technique [0002] With the rapid development of Internet and Internet of Things technology, various new business demands continue to emerge, prompting the explosive growth of mobile data traffic in the past ten years. In order to meet the requirements of higher network data transmission rate and better user data experience in the future mobile communication network, the future 5G communication technology needs to solve the above problems through a series of key technologies. In addition to increasing spectrum bandwidth and improving spectrum utilization, the most effective way is still to increase the degree of spatial reuse by increasing the density of cell deployment. [0003] Traditional communication systems reduce cell radius by adopting cell splitting. Howe...
