Embodiment Construction

[0028] The present invention will be further described below. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0029] Now, the standard of Component Carrier Allocation based on the Maximum SINR (CAMS) is described as follows:

[0030] (1) User r selects the initial serving small base station according to formula (1), if the set of these small base stations is the virtual cell Ω of user s s A subset of , then r and s are located in the same virtual cell Ω s .

[0031] (2) Each small base station in a virtual cell uses the same CC to provide services for users in the virtual cell.

[0032] (3) If the small base station m wants to serve users in different virtual cells, then for a certain CC, the small base station always uses this CC to serve the user that receives the strongest signal from the base station. For example, suppose the small base sta...

Abstract

The invention discloses a virtual cell carrier allocation method based on maximum SINR. The method comprises the following steps: determining an initial service virtual cell, judging whether the initial service virtual cell belongs to existing virtual cells, if not, determining target carriers, calculating a small base station set using the target carriers to serve the existing virtual cells, determining a signal-to-noise ratio, and selecting the target carriers. According to the invention, through mutual cooperation between the virtual cells, small base stations with better service quality are made to exit from certain original virtual cells, and corresponding component carriers are used to serve users in a virtual cell which the base stations are newly added to. The signal receiving quality of cell-edge users and the system average spectral efficiency can be improved, and the system capacity is enhanced.

Description

technical field [0001] The invention relates to a maximum SINR-based virtual cell carrier allocation method, which belongs to the technical field of mobile communication. Background technique [0002] In recent years, with the rapid popularization of smart terminals, mobile network data usage has shown explosive growth. The rapid growth of mobile data traffic has made the contradiction between limited wireless network resources and rapidly expanding user demands increasingly prominent. Obviously, the third-generation mobile communication network is difficult to meet the needs of today's people due to its limitations in system capacity and transmission rate. Therefore, it is necessary to take various measures to adjust and improve to cope with the impact of large data traffic. [0003] With the continuous evolution of LTE-Advanced, the deployment of small base stations will be very dense, and the distance between small base stations can reach 10 meters or less, thus forming ...
