Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific examples.

[0039] Assuming that a wireless mobile communication network includes S adjacent cells, each cell is divided into N available sub-channels, and each cell has a total of I users that are randomly and evenly distributed in the air space, and the cell ownership of each user is determined. is the user set in cell s, I s is the number of users in cell s. define beta s,i,n ∈{0,1} is the resource allocation indicator, β s,i,n =1 means that the nth subchannel in cell s is assigned to user i, otherwise β s,i,n =0. In order to avoid co-channel interference in the cell, it is stipulated that each subchannel can only be allocated to one user at most, that is,

Abstract

The invention discloses a sub-channel distribution method based on efficacy, and belongs to the technical field of resource distribution in the wireless mobile communication network. The sub-channel distribution method based on efficacy particularly comprises the following steps: determining an initial sub-channel distribution plan, changing the user to which a free sub-channel belongs as the user with the largest rate in the sub-channel on the basis of the initial sub-channel distribution plan, selecting a non-free sub-channel according to the improvable space of the rate from big to small, and carrying out substitution operation on the non-free sub-channel. On the premise of ensuring the requirement of the rate of each user, the method can reasonably distribute sub-channels to the cell users, and enable the total efficacy of a cell to be maximum, thereby improving the energy efficiency.

Description

technical field [0001] The invention belongs to the technical field of resource allocation in a wireless mobile communication network, and in particular relates to a subchannel allocation method in a wireless mobile communication network. Background technique [0002] With the improvement of the scale of wireless mobile communication network and its data rate requirements, the energy consumed in the communication process has increased significantly, the emission of greenhouse gases has continued to increase, and the environmental pollution caused has become increasingly serious. The issue of energy saving has attracted the attention of the whole society. Green The concept of communication came into being. It is not only a core topic in the field of communication, but also a major obstacle to sustainable development. Facing the severe challenge of wireless communication energy consumption, focusing on resource utilization efficiency, saving energy consumption required for ne...
