Method for requesting bandwidth of relay station

Abstract

A bandwidth request method of a relay station is characterized in sending a bandwidth request to a base station affiliated to the relay station by using a fixed intervals mode and a burst mode; the fixed intervals mode refers to periodically sending a bandwidth request with fixed intervals; the burst mode refers to sending a bandwidth request when the statistic of one or more or combined resourceservice information and the set corresponding statistic threshold of the resource service information meet a set correlation; the bandwidth request which is transmitted by using the burst mode includes the resource service information statistic and the corresponding resource service information statistic threshold which meet the set correlation, or includes information for indentifying that the resource service information statistic and the set corresponding resource service information statistic threshold meet the set correlation; the relay station is a non-transparent relay station; and thecorrelation includes larger than, smaller than, larger than or equal to, and smaller than or equal to.

Description

technical field [0001] The invention relates to a bandwidth request method of a relay station, in particular to a bandwidth request method of a non-transparent relay station. Background technique [0002] In the next-generation wireless communication network, it is necessary to solve the problem of defective areas within the coverage of the base station (Base Station, referred to as BS), so that the area not covered by the base station can be covered; and the capacity problem within the coverage of the base station, including the cell Capacity allocation between different areas in the same area and capacity allocation in adjacent cells. The above problems cannot be effectively solved, making indoor coverage models in buildings such as subway stations, tunnels or other underground buildings, as well as some temporary application models and mobile vehicles and other application models or the coverage and throughput of users at the edge of the cell, etc. The problem faces seve...

Problems solved by technology

[0016] 2. Bandwidth request method: The bandwidth request method sent by the relay station and the information contained in the request are single, and the BS cannot fully judge the actual resources, bandwidth occupation, and user request of the relay station based on the information contained in the request, and the bandwidth request efficiency is low;

[0017] 3. Bandwidth allocation method: when the base station allocates bandwidth for the relay station, the service priority is used as the priority of bandwidth allocation, and the judgment condition is single. When a high-priority service continuously sends bandwidth requests, for low-priority services, even if Even a small amount of bandwidth requirements will not be met for a long time, which is unfair
