Abstract

The invention provides an end-to-end communication power control method under a cellular heterogeneous network, which can reduce the interference on cellular user equipment. The method comprises the following steps: when applying for spectrum resources, the relay-assisted end-to-end user equipment establishes communication by multiplexing an uplink of cellular user equipment; wherein the relay, the end-to-end user equipment pair and the cellular user equipment in the communication cell are randomly distributed, and the end-to-end user equipment pair comprises an end-to-end transmitting end andan end-to-end receiving end; based on a preset constraint condition, power control is performed on the transmitting end and the relay of the end-to-end link to obtain the optimal transmitting power of the end-to-end transmitting end and the relay transmitting end when the system spectrum efficiency reaches the maximum; wherein the constraint condition comprises that the signal to interference plus noise ratio of signals received by the cellular user link and the end-to-end link is greater than a preset threshold value. The invention relates to the field of wireless communication.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an end-to-end communication power control method in a cellular heterogeneous network. Background technique [0002] When two cellular user equipments are in close proximity, peer-to-peer (Device-to-Device, D2D) communication can be established. When the spectrum resources in the communication cell are not enough, the D2D user equipment (D2D User Equipment, DUE) can transmit data by multiplexing cellular resources, which can increase the spectrum efficiency of the system, but at the same time, it will also affect the Equipment, CUE) links cause non-negligible interference. Therefore, in order to maximize the spectral efficiency of the system, it is necessary to balance the interference between CUE and DUE. [0003] In order to alleviate the interference caused by the reuse of cellular resources to the cellular link, most of the existing power control methods focus on the D2...
