摘要： User specific modulation-symbol scrambling is implemented for various uplink segments, e.g., uplink traffic acknowledgement channel (ULTACH), uplink state request channel (ULSRCH), and uplink dedicated control channel (ULDCCH) segments. A wireless terminal is assigned a wireless terminal scrambling identifier. A set of ordered input modulation symbols are determined for an uplink dedicated segment to which user specific scrambling is to be applied. One bit of the assigned wireless terminal scrambling identifier is associated with each of the ordered input modulation symbols of a segment in accordance with a predetermined mapping. For each input modulation symbol a scrambling operation, e.g., a phase rotation of the input modulation symbol, is performed as a function of the associated user specific scrambling identifier bit to obtain a corresponding output modulation symbol. A value of (0,1) for a scrambling ID bit is associated with a (first, second) amount of phase rotation, e.g., (0, 180) degrees, respectively.
