Orthogonal cover code (OCC) sequences design for uplink transmissions

Abstract:

The present disclosure relates generally to wireless communication systems, and more particularly, to a design for generating and utilizing orthogonal cover code (OCC) sequences for physical uplink control channel (PUCCH) transmissions. An exemplary method includes a user equipment (UE) selecting an orthogonal cover code (OCC) sequence for an uplink transmission, wherein the OCC sequence is selected from a first set of OCC sequences designed to achieve target peak to average power ratios (PAPRs) for a plurality of different modulation schemes; and transmitting the uplink transmission, via a wireless medium, with one of the modulation schemes using the selected OCC sequence.
