Scheduling method, relay node and base station

Abstract

The invention provides a scheduling method, a relay node and a base station. The scheduling method comprises the steps that: the relay node receives a corresponding first CQI of each scheduling resource unit on a down link between the relay node and first UE, wherein each scheduling resource unit is served by the relay node and reported by the first UE, and figures a corresponding second CQI of each scheduling resource unit on a back link between the base station and the relay node; a corresponding equivalent CQI of every scheduling resource unit is obtained according to the corresponding first CQI and the second CQI of every scheduling resource unit; a target equivalent CQI is determined from all the equivalent CQIs and reported to the base station; the base station carries out resource scheduling on the first UE and second UE according to a corresponding third CQI of every scheduling resource unit which is directly served by the base station and reported by the second UE and the target equivalent CQI reported by the relay node. The problem of resource scheduling after a relay is introduced is solved.

Description

technical field [0001] The present invention relates to communication technology, in particular to a scheduling method, a relay node and a base station. Background technique [0002] The 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) long-term evolution (Long Term Evaluation, referred to as LTE) project has carried out a comprehensive improvement on the basis of the 3G system. The complexity and multi-layered network structure bring challenges to network operation and maintenance. In order to overcome multipath fading and improve spectrum utilization efficiency, the LTE system adopts a dynamic resource allocation mechanism, in which the Medium Access Control (MAC) layer of the evolved base station (eNodeB, eNB) in the LTE system is responsible for managing Resource scheduling for uplink and downlink channels. [0003] As an evolved version of LTE, LTE-A introduced relay technology in R10 to improve the coverage of the system, r...

Problems solved by technology

[0002] The 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) Long Term Evaluation (referred to as LTE) project has carried out comprehensive improvements on the basis of the 3G system. On the one hand, the network performance is greatly improved, on the other hand, the network parameters are complicated and the network structure is multi-layered, which brings challenges to network operation and maintenance.

After the introduction of the relay, the eNB in ​​the macro cell needs to schedule the radio resources of the macro cell and the relay cell at the same time, but the current existing method is limited to the direct transmission from the eNB to the user equipment (User Equipment, referred to as UE) and does not involve The UE scheduling problem in the relay cell, so a method is needed to solve the resource scheduling problem after the introduction of the relay
