Problems solved by technology

[0003] However, in this traditional relay forwarding method, many transmission stages will inevitably lead to a decrease in spectral efficiency and affect other performances of the system. In addition, when multiple relay nodes participate in data relay forwarding, it will inevitably lead to increased scheduling overhead. and increased power consumption
[0004] The existing relay forwarding method has centralized resource allocation and scheduling for the traditional relay forwarding method to improve the spectrum efficiency and power efficiency of the communication system, but it needs sufficient information feedback requirements and time delay, etc., so the existing The relay forwarding method cannot meet the requirements of high spectral efficiency and energy saving without knowing all channel gain information

Abstract

The invention provides a broadband wireless communication relay dispatching method. Integral channel gain information is not needed, and an initial node decides whether a relay transmission mode is adopted or not; a selected relay node detects whether data are forwarded or not according to the local channel gain information. According to the broadband wireless communication relay dispatching method, the transmission space diversity capacity is improved while the dispatching expenditure between the nodes is reduced, and therefore the communication stopping probability is reduced; the total transmission power of the system is reduced while the service quality of the system is ensured.

Description

technical field [0001] The invention relates to the field of wireless network data transmission, in particular to a broadband wireless communication relay scheduling method. Background technique [0002] The goal of next-generation broadband wireless communication is to provide higher transmission rates, higher spectrum utilization, and greater coverage, and relay forwarding is a simple, anti-multipath interference and effective coverage of wireless network data transmission technology. In the relay forwarding method of the traditional two-way communication system, the two originating nodes transmit information to each other with the help of the relay node, which mainly includes the following steps: send the data to the originating node to the relay node in the first stage before relay forwarding , and then send the data to the second-stage relay node to the destination node before relay forwarding, the destination node sends the data to the relay node in the first stage of...
