Embodiment Construction

[0058] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0059] According to matching theory, because one user can access multiple base stations and one base station can access multiple users, the split multiple access problem to be solved is a many-to-many matching game problem. When a user accesses multiple base stations, both the uplink access base station and the downlink access base station are included, and the uplink access and the downlink access interfere with each other. Therefore, simply considering the many-to-many...

Abstract

The invention discloses a matching game-based separation multi-access method in an ultra dense heterogeneous network. The method is based on a user separation multi-access mechanism, that is, user equipment is allowed to access multiple base stations in uplink and downlink so as to enjoy services and transmit data. The invention provides a low-complexity matching game method based on a matching game theory. One or more base stations are selected for a user to connect according to quality of service requirements of the user, user utility in the network is maximized, further, actual needs of different users are met. The problem of user separation multi-access in the ultra dense network is solved through the matching game method, so that the user utility in the network is maximized and the quality of service requirements of different users are met. Compared with traditional exhaustive search and branch and bound methods, the method has the advantage of low complexity. The method represents a new possibility solving the problem of user multi-access in the ultra dense network.

Description

technical field [0001] The invention discloses a user separation and multi-access method based on a matching game method in an ultra-dense heterogeneous network, which is mainly used to solve the access problem of users and base stations by using a matching game method in an ultra-dense heterogeneous network. At the same time to meet the quality of service needs of different users. Background technique [0002] With the introduction of new technologies such as network structure densification and heterogeneity, many basic issues in wireless communication networks need to be re-studied, and user access is one of them. In a wireless communication network, especially an ultra-dense heterogeneous network, a wireless terminal is usually within the service range of multiple base stations. The user access problem is the problem of selecting a base station for wireless terminals to access for service and data transmission. However, the development of ultra-dense networks has brough...
