Method and apparatus for generating an uplink reference signal sequence in a wireless communication system

摘要

The present invention provides a method and apparatus for generating a reference signal sequence by user equipment (UE) in a wireless communication system. The UE receives a UE-specific sequence group hopping (SGH) parameter that is specific to itself, and generates a reference signal sequence based on a base sequence in each slot unit. The base sequence is classified into sequence-group numbers determined in each of the slot units by the UE-specific SGH parameter indicating whether SGH has been carried out, and base sequence numbers.

1. A method of generating, by a user equipment (UE), a reference signal sequence in a wireless communication system, the method comprising:
receiving a cell-specific sequence group hopping (SGH) parameter from a base station, the cell-specific SGH parameter is used to enable a sequence group hopping for a plurality of UEs in a cell; receiving a UE-specific SGH parameter, specified to the UE, from the base station, the UE-specific SGH parameter is used to disable the sequence group hopping, enabled by the cell-specific SGH parameter, for the UE; and generating the reference signal sequence based on a base sequence and a sequence group number, wherein the sequence group number is determined by the UE-specific SGH parameter.
