Abstract

The invention discloses a method and a device for the frequency allocation of a relay system, relating to wireless communication system and solving the problem that the current relay system fails to allocate frequency resources to relay stations reasonably. The allocation method according to the embodiment of the invention comprises the steps: determining a target relay station requiring resource allocation; allocating frequency resources to the target relay station according to the utilization condition of frequency resources in the relay system, wherein the frequency resources are used for the target relay station and terminals the target relay station serves. The device according to the embodiment of the invention comprises: a determination unit for determining the target relay station requiring resource allocation; an allocation unit for allocating frequency resources to the target relay station according to the utilization condition of frequency resources in the relay system, wherein the frequency resources are used for the target relay station and terminals the target relay station serves. The method and the system are mainly used in base stations of the relay system.

Description

Technical field

[0001] The present invention relates to a wireless communication system, and in particular to a method and device for frequency allocation in a relay system provided with a relay station. Background technique

[0002] The wireless communication system generally adopts a cellular network structure. If all mobile terminals (MS) and base stations (BS) in the cellular network communicate directly, it is called a single-hop network; if some mobile terminals in the cellular network need to pass The relay station (RS) communicates with the base station, which is called a multi-hop network, also called a relay system. Among them, a single-hop network includes two endpoints, a BS and an MS, and a relay system includes a BS, an MS, and an RS, and the BS can support multi-hop relay.

[0003] In cellular networks, frequency reuse is generally used to improve the spectrum utilization of the communication system. For single-hop networks, since the communication frequencies used ...
