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

摘要

Methods and User Equipment (UE) apparatuses are provided for transmitting Reference Signals (RSs). A method includes receiving a cell-specific sequence-hopping parameter; receiving a UE-specific sequence-hopping parameter; determining a reference signal sequence based on the UE-specific sequence-hopping parameter; and transmitting the reference signal based on the determined reference signal sequence. Sequence hopping does not apply to the reference signal sequence if the cell-specific sequence-hopping parameter indicates that the sequence hopping is enabled and the UE-specific sequence-hopping parameter indicates that the sequence hopping is disabled.
