Abstract
The present invention provides a device and method for performing device-to-device broadcast communication in a wireless communication network, wherein the method comprises the steps of: obtaining a row except a 1st row for device-to-device broadcast in a Walsh matrix; performing device-to-device broadcast based on a transmission pattern determined by the obtained row, wherein the transmission pattern is: performing the following operations based on each element in the row sequentially: when the element is a first value, performing broadcast transmission of a same data packet; when the element is a second value, performing broadcast reception. Compared with the prior art, the present invention overcomes semi-duplexing limitation and reduces in-band emission, thereby achieves a better system performance.
