Abstract

The present invention provides a device and method for performing a device-to-device broadcast communication in a wireless communication network, wherein the method comprises steps of: selecting a transmission resource; estimating signal interference of broadcasting on the transmission resource based on signal intensity of other user equipments that simultaneously transmit signals on the transmission resource or on a frequency resource orthogonal to the transmission resource; based on the estimated signal interference, determining whether to perform a device-to-device broadcast communication on the selected transmission resource. Compared with the prior art, the present invention needs no much extra overhead, effectively reduces signal interference between user equipments that transmit simultaneously, and thereby achieves a better system performance.
