Abstract (en)

[origin: WO2015173644A1] The invention provides a method, in a user equipment in a wireless communication network, of implementing Device-to-Device broadcast communication, the method comprises following steps:- determining a transmission pattern set, which includes all rows except the first row in a Walsh matrix H1 and a first matrix H2, wherein the first matrix H2 is a product of the Walsh matrix H1 and -1;- determining one row from the transmission pattern set; and- implement a Device-to-Device broadcast according to a transmission pattern corresponding to the determined row, wherein the transmission pattern is: implementing the following procedures based on each element in the determined row successively:- transmitting the broadcast when the element is a first value;- receiving the broadcast when the element is a second value.
