METHOD AND DEVICE FOR DETERMINING COMMUNICATION RESOURCES IN RELAY NETWORK

摘要

A method and device for determining communication resources in a relay network are provided in the invention for reducing resource waste caused by the mismatch of the rates of multiple hop relay links, and the method includes the following steps: obtaining feed-back information of multiple links; respectively allocating and scheduling communication resources for each link according to the feed-back information of the multiple links; estimating transmission rate of each link according to the communication resources of each link; judging whether the transmission rate of each link is matched: if they are not matched, the communication resources allocated to at least one link among the multiple links is adjusted, and the estimating step, the judging step and the adjusting step are repeated until they are matched; if it is matched, the corresponding communication resources are determined to be used by each link. With the invention, multiple hop relay links of rate-matching are acquired, utilization of the whole resources is improved, delay of data packets is reduced, the invention is easy to realize and commonly used in resource allocating and scheduling strategies of centralized and distributed architecture, relay scenes of two hops and above are supported, and the invention is also well compatible with existing resource allocating and scheduling technique.
