APPLICATION OF SEQUENCE HOPPING AND ORTHOGONAL COVERING CODES TO UPLINK REFERENCE SIGNALS

摘要

Methods and apparatuses are provided to enable User Equipments (UEs) to apply Orthogonal Covering Codes (OCC) to the transmission of Reference Signals (RS) generated from Constant Amplitude Zero Auto-Correlation (CAZAC) sequences, to enable hopping of these sequences in a communication system in conjunction with enabling the application of OCC, and to differentiate the application of sequence hopping between transmissions in data channels and transmissions in control channels.
