Problems solved by technology

[0003] Frequency bands below 6GHz have good channel propagation characteristics and are very suitable for mobile communication applications. However, frequency resources in low-frequency bands are very scarce at present, and it is difficult to find continuous large-bandwidth frequency resources.
[0006] In order to overcome the high path loss, the terminal and the high-frequency base station may need to use beamforming technology to establish a connection. The two may need to scan all directions to make the beam match successful. This process will consume a lot of energy and time.
However, even with beamforming technology, high-frequency communication can only cover part of the area. After the terminal turns on the high-frequency communication module, it may not be able to successfully establish a high-frequency link, resulting in unnecessary transmission time and power overhead.

Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and examples.

[0017] In the embodiment of the present application, a high-low frequency fusion wireless access method is provided. By accumulatively measuring the channel gains between the terminal, the high-frequency base station, and the low-frequency base station, the empirical distribution of the high-frequency channel gain and the channel gain under each high-frequency channel gain condition are obtained. Empirical conditional distribution of low-frequency channel gain; based on the obtained empirical distribution and empirical conditional distribution, the low-frequency channel gain is used to select the timing for the terminal to start high-frequency communication and the high-frequency base station suitable for establishing a link with it. Th...

Abstract

The invention provides a high and low frequency fused wireless access method, which comprises the following steps of obtaining empirical distribution of high frequency channel gains and empirical condition distribution of low frequency channel gains under each high frequency channel gain condition through accumulative measurement of channel gains between a terminal and a high frequency base station and between the terminal and a low frequency base station; and utilizing the low frequency channel gains to select an opportunity for the terminal to start high frequency communication and the high frequency base station which is suitable for establishing a link with the terminal based on the obtained empirical distribution and the empirical condition distribution. According to the technical scheme, a process for determining whether to use the high frequency link can be optimized and the meaningless high frequency communication startup time and the energy consumption can be reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a high and low frequency fusion wireless access method. Background technique [0002] In order to meet the rapidly growing demand for mobile data traffic, future mobile communication systems need more spectrum resources. [0003] Frequency bands below 6 GHz have good channel propagation characteristics and are very suitable for mobile communication applications. However, frequency resources in low-frequency bands are very scarce at present, and it is difficult to find continuous large-bandwidth frequency resources. In order to meet the needs of future mobile communication services, it is necessary to make full use of various available frequency resources. There are a large number of idle spectrum resources above 6GHz, which can effectively alleviate the shortage of spectrum resources in the future. Therefore, high-frequency communication operating above 6GHz has also beco...
