Abstract  Abstract

A transmission of information from a secondary to a primary node occurs in a plurality of N logical time durations. The transmission from the secondary to primary node in a wireless network (100) is obtained using a first and a second sequence. Embodiments of the present invention mitigate interference by restricting the choice of the first sequence. Thus in an embodiment of the invention the first sequence is selected from a set of M sequences wherein M is strictly less than N. In order to accommodate high-velocity (112) users the restricted set contains a pair of sequences whose element-wise product is mirror symmetric. A transmission component for K-th logical time duration is obtained from the entire second sequence and K-th element of the first sequence.
