CONTROL METHOD FOR WIRELESS POWER TRANSFER APPARATUS CONSIDERING INTERFERENCE IN WIRELESS POWERED COMMUNICATION NETWORKS AND WIRELESS POWER TRANSFER APPARATUS

摘要

In the present invention, provided are a method for controlling a wireless power transmission apparatus in consideration with interference in a wireless power communications network, and a wireless power transmission apparatus. The method for controlling the wireless power transmission apparatus of the present invention comprises: a step in which at least one wireless power transmission apparatus performs a distributed coordination function (DCF)-based contention process with at least one wireless communications terminal; and a step in which the wireless power transmission apparatus prevailing in the DCF-based contention process transmits an energy frame to the at least one wireless communications terminal. The wireless power transmission apparatus of the present invention comprises: a communications module for selecting any integer within a contention window, and selecting the same as a backoff value to perform the DCF-based contention process with the at least one wireless communications terminal; a power transmission module for transmitting the energy frame to the at least one wireless communications terminal in case of prevailing in the DCF-contention process; and a processor for controlling the communications module and the power transmission module. According to the present invention, interference can be reduced, and the performance of a wireless power communications network can be improved.
