Abstract

The invention provides a method for realizing a pilot frequency wireless relay. A downlink processing unit and a monitoring unit are arranged in a relay device, and the method comprises the following steps: enabling the downlink processing unit to receive a first radio frequency signal RF1 from a base station (CAP) and convert the first radio frequency signal RF1 into an intermediate frequency signal; converting the intermediate frequency signal into a second radio frequency signal RF2, and transmitting the second radio frequency signal RF2 to a user terminal (STA); enabling the monitoring unit to receive a fifth radio frequency signal RF5 from a base station (CAP) and convert the RF5 signal into an intermediate frequency signal; processing and analyzing the intermediate frequency signal to obtain a working frequency and a signal bandwidth required by the relay; and setting a second radio frequency signal RF2 according to the working frequency and the signal bandwidth indication. By adopting the wireless relay method and device provided by the invention, the working frequency band can be changed, namely the same-frequency and different-frequency relay operation is supported, the time delay characteristic is low, the anti-interference performance is realized, the working mode is simple, and a certain multi-frequency-band mesh function is realized. A transmitting channel and a receiving channel in the invention are not realized by adopting conventional LNA and PA, but a radio frequency transceiver is added, so that flexible choices are provided for the relay device to work at the same frequency or different frequencies with a base station.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a wireless relay device and an implementation method thereof. Background technique [0002] Next Generation Broadcasting network (NGB for short) is a next-generation broadcasting network that is suitable for my country's national conditions, "triple play", a combination of wired and wireless, and a full network. It is the leading and supporting triple play important means of development. Among them, the NGB wireless system (NGB-Wireless, referred to as NGB-W) needs to combine the advantages of radio and television wireless transmission technology and wireless broadband communication technology. In order to meet the comprehensive business needs of users, NGB-W should provide one-way broadcast, data push, two-way Interactive and broadband two-way access and other network services. [0003] In order to meet the various business needs of NGB-W, it is neces...
