BRadio (Band Radio) wireless access system and signal transmission, networking and service method

Abstract

The invention relates to a BRadio (Broadband Radio) wireless access system and a signal transmission, networking and service method, which belong to the technical field of broadband radio communication. The system is a broadband radio access system based on a BRadio technology and comprises a downlink link and an uplink link, wherein a TFU-OFDMA (Time domain and Frequency domain United Orthogonal Frequency Division Multiple Access) technology is adopted by the downlink link of the system while a TFU-SCMA (Time domain and Frequency domain United-Single Carrier Multiple Access) technology is adopted by the uplink link. The method comprises a time division duplex or frequency division duplex signal transmission method adopted by the downlink link and the uplink link, a networking method for reducing interference between cells by adopting an interleave division multiple access technology and a service method adopting a content and channel sharing based personal media service technology. The BRadio system in the invention supports multiple encoding methods and supports TDD (Time Division Duplex) or FDD (Frequency Division Duplex), can very flexibly configure radio resources, supports various channel environments and various multimedia and stream media services and supports wide-area coverage under high speed mobile environments. The system can be applied to fields like e-government affairs, e-commerce, mobile office and tourist recreation.

Description

technical field [0001] The invention belongs to the technical field of broadband wireless communication, and relates to a dedicated broadband wireless access system and its signal transmission, networking and service methods. Background technique [0002] With the development trend of Internet Protocol (Internet Protocol, hereinafter referred to as IP), broadband, mobile and business diversification and the continuous improvement of social living standards, traditional and pure voice services can no longer meet the requirements People's needs, especially with the rapid development of the Internet, people hope to enjoy multimedia, diversified and personalized communication services, and the surge in data traffic makes people's demand for communication bandwidth increasingly high. Although optical fiber access represents the direction of future broadband access, it also has certain disadvantages. The biggest problem with optical fiber access is that the cost is still relative...
