Abstract

A method is provided for block spreading individual control symbol sequences, mapping the block spread control symbol sequences, adding a cyclic prefix to the block spread control symbol sequences to form a data-non-associated control signaling information, and transmitting the data-non-associated control signaling information.

Claims
