Distribution method of multi-user parallel transmission resource in wireless heterogeneous network

Abstract

The invention discloses a distribution method of multi-user parallel transmission resource in wireless heterogeneous network and mainly aims to solving the problem that the existing heterogeneous network source distribution technology cannot distribute the resource to concurrent shunt users; the distribution method comprises the steps that, (1), when a resource allocation cycle is coming, users report the detected channel quality indication information to each wireless access network, and report rate statistical information and resource request to a joint radio resource management module; (2), the wireless access network calculates the amount of the resource in each resource unit capable of being provided to users, and reports the resource amount and the channel quality indication information to the joint radio resource management module; (3), the joint radio resource management module calculates the priority of each user, and then sequentially distribute the resources to the users from high priority to low priority; and (4), the joint radio resource management module sends the resource distribution result to each wireless access network, and then the wireless access networks finish the user resource allocation. The distribution method has the advantages of high network resource use efficiency.

Problems solved by technology

For the case of concurrent distribution of multiple users, only the method of user access selection is proposed at present, and the method of which system the user should choose to access is given from various perspectives. Since multi-user resource allocation involves complex optimization problems, so No specific channel resource allocation method has been proposed so far

When multiple users supporting concurrent traffic distribution are covered by a heterogeneous network at the same time, how to decide whether a certain user accesses one system or multiple systems to receive services through concurrent traffic distribution, and how to grasp which users should be served as a whole Which systems are connected, and how to allocate different resources of different systems to users? These problems are the great challenges faced by heterogeneous network resource allocation
