Embodiment Construction

[0042] Functional Overview

[0043] Embodiments of the present invention provide a centralized resource scheduling method and device. In the above method, by dividing the proportion of resources occupied by UEs in the BS domain and UEs in the relay domain, unified scheduling is performed for UEs in the BS domain and UEs in the relay domain. Prioritize the allocation of resources. At the same time, the resource division ratio can be flexibly set according to network design requirements and performance requirements, and cell resources can be pre-allocated, and according to the amount of data transmitted from RS to relay domain UE and BS to RS The principle of equal quantity is used to reallocate resources. The present invention will be described in detail below with reference to the accompanying drawings and examples.

Abstract

The invention discloses a centralized resource scheduling method and a device. The method is applied to a mobile communication system containing a relay station and comprises the following operations: according to preset information, setting resource scheduling indication information which is used for indicating the ratio of the resources which can be distributed into a base station field user terminal and / or relay field user terminal in available cell resources, wherein the preset information comprises one of or the combination of the following components: a measurement report, service requirements and load distribution; according to the resource scheduling indication information, carrying out resource scheduling on the base station field user terminal and the relay field user terminal. The invention realizes scheduling fairness.

Description

technical field [0001] The present invention relates to the communication field, in particular to a centralized resource scheduling method and device applied to a communication system including a relay station. Background technique [0002] At present, the development of mobile communication requires support for higher transmission rate, better signal coverage and higher resource utilization. In order to achieve a high transmission rate, the communication system will use a higher frequency band to transmit signals, but on the other hand, high frequency will bring large path loss, which will affect network coverage. In order to effectively improve network coverage, improve network capacity and resource utilization, a relay (Relay) technology is proposed. [0003] Relay technology is regarded as a key technology of 4G. After the introduction of relay technology, the structure of the network will change. The added relay station (Relay Station, referred to as RS) needs to use p...
