Problems solved by technology
In the absence of coordination between low-frequency traditional cellular communication and high-frequency millimeter wave communication, independent wireless signal transmission often breaks through the total power limit, thus violating the corresponding radio management regulations
The existing technology adjusts and optimizes time-sharing switching through various means, but all of them lead to a substantial increase in the amount of data processed by the entire system including the terminal, occupying additional computing resources

The invention provides a millimeter wave cooperative transmission method and device. The method comprises the steps that real-time transmitting state information of one or more low frequencies is acquired from baseband signal processing equipment of the low frequencies, time labels of low-frequency signals are extracted from the real-time transmitting state information, non-ideal factors are acquired, and the guard interval is comprehensively calculated; and corresponding transmitting interval information in different modes is generated according to the guard interval and low-frequency transmission modes, the guard interval is added into the transmitting interval information, a millimeter wave signal optimizing interval is generated and output through baseband processing equipment of high-frequency millimeter wave signals; and the real-time transmitting state information comprises the transmission modes and the time labels of the low frequencies. According to the method and device, before transmission in millimeter wave communication is conducted, the transmission modes and the time labels of low-frequency communication are acquired in advance, transmitting windows of millimeter wave communication are configured through stations according to the information, and the sending efficiency is improved as much as possible on the condition of not violating limitation of total power.
Description
technical field [0001] The present invention relates to a technology in the field of wireless transmission, in particular to a multi-band signal transmission site that can be used for various types of total power limited, including but not limited to multi-band cellular networks, wireless local area (Wi-Fi ) networks and various heterogeneous networks composed of cellular networks and wireless local area networks and other scenarios, such as millimeter wave cooperative transmission devices and methods. Background technique [0002] For the fifth generation mobile communication system, since the site resources of the mobile communication network are very limited, the low-band (<6GHz) communication for network coverage performance and the high-band mmWave communication for increasing the transmission rate are often deployed on the same site , to save site resources. But correspondingly, the total power that each site can transmit radio wave signals is often limited. In th...
