Block spreading generating partial orthogonality is applied for the uplink control channel for E-UTRA. For instance, a problem of maximizing the multiplexing capacity leads to numerology causing odd-length sequences which do not have the favorable property of even-length sequences (partial orthogonality). The consequence of this is poor performance in cases of high Doppler effects. Maximal multiplexing capacity is taught without loss of performance at high Doppler by modifying an earlier scheduling request scheme. The earlier SR multiplexing scheme has a number of parallel SR resources per slot equal to 12*7=84. In one example, the spreading factor of block spreading is changed to an even number, e.g., from 7 to 6. This enables usage of the partial orthogonality properties of CAZAC sequences and as a result inter-code interference in the case of high Doppler is reduced. Other ways to generate partial orthogonality are shown with similar results.
