Abstract

The invention discloses a mode selection and switching method in a double-frequency integrated system, and mainly solves the problems that in the prior art, when a communication sub-module is switched, flexibility is not achieved, and communication transmission is likely to be interrupted. According to the implementation scheme, the method comprises the following steps that: 1), a base station performs initial access and performs data transmission by using a C waveband; 2), the base station simultaneously carries out initial detection on a millimeter wave band channel; 3), the base station selects a current data transmission frequency band according to the initial detection condition and the user service demand type; 4), the base station performs corresponding data transmission state tracking according to the currently selected data transmission frequency band; and 5), when the initial detection time interval reaches 200ms, the base station sends a detection signal again, and performsdata transmission frequency band switching according to the detection condition. According to the invention, the C waveband and the millimeter waveband are integrated, so that the frequency band switching is more flexible, the effectiveness and reliability of data transmission are improved, the transmission interruption when the channel condition is changed can be avoided, and the method can be used for wireless communication.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a mode selection and switching method in a dual-frequency integrated system, which can be used for self-adaptive switching of working frequency bands when a communication link is interrupted or performance is degraded. Background technique [0002] The dual-frequency integrated system consists of C-band and millimeter-wave frequency bands, ensuring that the communication system will not be interrupted when the channel conditions change. Among them, the C-band is a frequency band with a frequency of 4.0G-8.0GHz. It is also the most important communication frequency band in the 4G era. It has the characteristics of mature technology, perfect infrastructure, strong signal penetration ability, and large coverage. However, due to the increasing shortage of C-band spectrum resources and the increasing demand for mobile communications, the development and utilization o...
