Embodiment Construction

[0019] Specific embodiments of the present invention are described below with reference to the accompanying drawings. For the sake of clarity, details and functions not necessary for the present invention have been omitted during the following description.

[0020] figure 1 A schematic situation of resource scheduling of multi-user and multi-service in a two-hop cooperative network according to an embodiment of the present invention is shown.

[0021] Such as figure 1 As shown, in a cell, there are K users, R relay stations, N c subcarriers, for any subcarrier n, h (s，k)，n Indicates the channel response between the base station s and the kth user terminal, Indicates that the base station s and the i-th relay station R i The channel response between, Indicates the relay station R i The channel response with the kth end user. In the following description, it is assumed that the downlink transmission is performed and the base station s can obtain perfect channel state i...

Abstract

The invention discloses a multi-service diversity dispatching method of a multi-hop coordination network, which comprises: the respective performance evaluation sub-models are respectively established based on different QoS (Quality of Service) parameters in the multi-hop coordination network; a general resource dispatching model for evaluating the general service quality of the multi-hop coordination network is generated based on each sub-model; an optimization model is established based on the general resource dispatching model; and the resource dispatching allocation is carried out on the communication system in the multi-hop coordination network based on the optimization model. The method has the advantages that the reasonable allocation of the system resources is realized based on the satisfaction degree of users on the service quality according to the method; and various QoS indexes in the resource dispatching can be flexibly satisfied.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multi-service scheduling method used in a multi-hop cooperative network. Background technique [0002] The main factor affecting the signal quality in the wireless transmission environment is channel fading, and the multi-antenna diversity method can effectively resist the fading of wireless channels and provide reliable information transmission for the system. In the mobile communication system, the traditional antenna diversity is at the receiving end, that is, the mobile station, which uses multiple antennas for receiving diversity. A typical Rake receiver uses multipath combining technology to obtain high diversity gain and good receiving performance. In the concept of cooperative communication and virtual antenna, user terminals relay each other, which can realize diversity reception of user terminals and obtain diversity gain without increasing the complexity and a...
