Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] The embodiment of the present invention can be used in a communication network, and a basic terminal, a D2D terminal and a base station can be set in the communication network. Wherein, the D2D terminal includes a D2D transmitter and a D2D receiver, and communication between the D2D transmitter and the D2D receiver may be collectively referred to as D2D communication. Such as figure 1 In the communication network shown, multiple cellular users, base st...

Abstract

The embodiment of the invention discloses a method and a device for determining an access frequency band based on D2D communication, relates to the technical field of communication, and can solve the problem that communication interference occurs between a D2D user and a cellular user and meanwhile achieve the maximal communication rate of the D2D user. The method provided by the embodiment of the invention comprises the steps of: determining a low-interference user set according to obtained first, second, third and fourth distances; obtaining a traversal rate when a D2D transmitter and a D2D receiver multiplex the uplink frequency band of a target cellular terminal during a D2D communication process according to an obtained fading parameter; determining the uplink frequency band corresponding to the maximal traversal rate to be the access parameter; and determining the optimal transmitting power of the D2D transmitter by comparing the transmitting power, the maximal transmitting power and the minimal transmitting power of the D2D transmitter. The method and device are applicable to a communication network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for determining an access frequency band based on D2D communication. Background technique [0002] With the development of communication technologies, especially the popularization of cellular networks, in order to effectively improve the spectrum utilization rate of cells, D2D (Device To Device, Direct Device Access) users are gradually introduced in cells. During the communication process, D2D users can directly transmit user data without going through the network, that is, user data can be directly transmitted between terminal A and terminal B that belong to the D2D user. Moreover, when communicating between D2D users, the uplink frequency band of the cellular users is used for data transmission. [0003] At present, in order to reduce communication interference between D2D users and cellular users during communication, resource allocation i...
