Method of realizing wireless link processing, base station and terminal

Abstract

The invention discloses a method of realizing wireless link processing, a base station and a terminal. The method comprises steps: a first communication node receives reference information from a second communication node, and link information for wireless link communication is determined; and according to the determined link information, the first communication node communicates with the second communication node. According to the reference information of the second communication node which serves as a receiving party, the link information for wireless link communication is determined, communication between the first communication node and the second communication node according to the determined link information is further realized, the problem that performance of the wireless link drops as receiving party channel features are changed completely and a spot beam coverage range is out completely in a high-speed moving communication environment can be solved, and the service quality of the overall mobile communication system is enhanced.

Description

technical field [0001] The present application relates to mobile communication technology, especially to a method for realizing wireless link processing, a base station and a terminal. Background technique [0002] With the development of smart terminals such as smartphones and tablet computers, such as cloud computing, Internet of Things, mobile phone video calls and conferences, online games, online music and picture downloads, etc. have driven a large-scale increase in wireless communication network users, resulting in wireless data Explosive growth of business. According to forecasts, in the next 10 years, wireless data services will increase by about 1000 times, with an average annual growth rate of about 2 times. [0003] In order to adapt to the growth of wireless data services, at present, the capacity of wireless communication networks is mainly increased by increasing spectrum bandwidth, strengthening business offload, increasing network density, and improving spe...

Problems solved by technology

At present, in order to provide users with good service quality in high-speed moving vehicles, it is mainly through installing relay stations on the vehicles, and the relay stations forward the downlink data sent by the base station (data sent by the base station to the terminal) to the terminal in the vehicle , the uplink data sent by the terminal in the vehicle (the data sent by the terminal to the base station) is forwarded to the corresponding base station. However, when the vehicle moves faster, the update of the channel state information between the relay station and the base station will not be timely, resulting in wireless The problem of link performance degradation

In addition, in the future mobile communication system, large-scale antenna array technology is the key technology to improve spectrum efficiency. Due to the large number of antennas, the sender can form a very thin spot beam, which is very important for the accuracy of the wireless channel between the sender and receiver. It also puts forward very high requirements on the mobile speed of the receiver. If the receiver moves at a high speed, it is very likely that the channel characteristics of the receiver will completely change when the sender sends data, and the receiver will completely leave the network. Coverage of spot beams is limited, resulting in degraded wireless link performance
