Problems solved by technology

[0002] At present, in order to solve the shortage of spectrum resources and increase the communication rate, people generally adopt D2D (device-to-device) technology with high speed and low power consumption, but D2D technology enhances the interference of cellular users to D2D users and the interference of D2D users to cellular chains. road interference, thereby reducing the data transfer rate between communications

Embodiment Construction

[0025] The following describes in detail the method for providing a cellular communication system terminal direct adaptive grouping and resource allocation method in combination with specific embodiments:

[0026] Such as Figure 1-2 As shown, the cellular communication system terminal direct adaptive grouping and resource allocation method includes the following steps:

[0027] (1) At the beginning, the community is divided into inner ring and outer ring;

[0028] The base station divides the regional cells into an inner ring and an outer ring according to the distance, and the outer ring adopts D2D communication technology.

[0029] (2) Divide the outer ring into multiple symmetrical areas, and there are three division methods corresponding to the three grouping modes, as follows figure 1 The three cell division methods in the figure, the same letters in the figure represent mutually symmetrical areas.

[0030] (3) Select the grouping mode according to the channel gain va...

Abstract

The invention discloses a method for direct-through self-adaptive grouping and resource allocating of cellular communication system terminals. The method includes: dividing an region cell into an inner ring and an outer ring by a base station according to distance; equably dividing the outer ring into three regions corresponding to grouping modes; selecting the grouping mode according to a channel gain value; calculating equivalent channel gain of every pair of D2D (device-to-device); selecting the D2D pair with the maximum channel gain in the equivalent region to multiplex a subcarrier; and repeating above steps till all subcarriers are distributed. By the aid of the method for direct-through self-adaptive grouping and resource allocating of the cellular communication system terminals, system capacity and spectrum efficiency of mobile communication D2D can be improved, mutual interference between honeycomb users and D2D users during communication is reduced, and requirement for high data rate of the D2D users is met.

Description

technical field [0001] The invention relates to the technical field of mobile communication resource allocation, in particular to a cellular communication system terminal direct adaptive grouping and resource allocation method. Background technique [0002] At present, in order to solve the shortage of spectrum resources and increase the communication rate, people generally adopt D2D (device-to-device) technology with high speed and low power consumption, but D2D technology enhances the interference of cellular users to D2D users and the interference of D2D users to cellular chains. road interference, thereby reducing the data transmission rate between communications. [0003] With the rapid development of mobile communication speed, how to effectively improve the capacity and spectrum utilization of mobile communication systems through resource allocation, reduce the interference of cellular users to D2D users between communications and the interference of D2D users to cell...
