Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] In the field of computer communications, backhaul refers to the transfer of data from a user terminal to an Internet server.

[0036] A utility function is used to map the bandwidth traffic allocated to a user to that user's "satisfaction" or "happiness." The utility function is monotonically constant, which means that the more bandwidth is allocated, the more "satisfaction" or "happiness" it brings. The main role of the utility function is that it can inherently reflect the user's traffic requirements and convey the degree of adaptation of the application.

[0037] BS={BS 1 ,BS 2 ,BS 3 ,...,BS i ,...,BS j ,...,BS n } represents a group of base stations, where i and j are both base station ordering labels, and n represents the total number of base stations. BS 1 On behalf of the macro base station, it is responsible for connecting to the...

Abstract

A link establishment method of a wireless communication system belongs to the technical field of radio transmission systems, and comprises the following steps: establishing a tree topology in which a father node and child nodes are arranged; each child node has and only has one father node; geographic distribution of base stations is given, the total number of antennas of each base station BSi is Ni, a father node of each base station BSi is found, and transmission antennas are distributed on two sides of each link, so that the total utility value of all the base stations is maximized. According to the scheme, the antenna distribution is dynamically adjusted while the route is selected, so that the overall satisfaction degree of the user is improved. According to channel conditions of links and geographic positions of available antennas and base stations, a wireless heterogeneous network backhaul topology is constructed, and a transmitting antenna and a receiving antenna of each link are adjusted, so that the overall effectiveness is improved to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of radio transmission systems, and in particular relates to a link establishment method of a wireless communication system. Background technique [0002] At present, large-scale input and output antenna arrays and heterogeneous wireless backhaul networks are considered to be leading technologies and research hotspots in the 5G field. [0003] A large-scale input and output antenna array refers to the transmitter and receiver of the base station equipped with multiple antennas, which can use multiple antennas to transmit and receive signals at the same time. Improve signal quality and transmission capacity. [0004] Heterogeneous wireless backhaul networks allow user equipment with different network standards to access small communities, and base stations in small communities access macro base stations through multi-hop connections to form a wireless backhaul network. Heterogeneous networks still have techn...
