Claim 8:
9. A user equipment (UE) comprising:
a plurality of circuit components to perform initial processing operations on data to be transmitted in an uplink (UL) data transmission from the UE to a base station, wherein the plurality of circuit components include:
an interleaver configured to generate an interleaved sequence;
a modulator coupled to the interleaver to receive the interleaved sequence, and configured to generate modulated symbols based on the interleaved sequence; and
a spreader coupled to the modulator to receive the modulated symbols, and configured to apply a block-wised orthogonal cover code to the modulated symbols, wherein the modulated symbols are given by d(0), . . . , d(Msym−1), where Msym is a number of the modulated symbols, and the spreader is to output, y
