Method and apparatus for generating reference signal sequence and for performing data scrambling in wireless communication system

A base station configured to transmit a reference signal in a wireless communication system, comprising:

• a transceiver;
• and
• a processor configured to control the transceiver,
• wherein the processor is configured to:
• generate a reference signal sequence;
• and
• transmit a reference signal corresponding to the generated reference signal sequence,
• wherein the reference signal sequence is generated using an initial sequence determined using a slot number in a transmission frame and a symbol number in a slot and a reference signal identifier (ID), and
• wherein the reference signal identifier is a scrambling identifier (ID).

A UE configured to receive a reference signal in a wireless communication system, comprising:

• a transceiver;
• and
• a processor configured to control the transceiver, wherein
• the processor is configured to:
• wherein receive a reference signal corresponding to a reference signal sequence,
• wherein the reference signal sequence is generated using an initial sequence determined using a slot number in a transmission frame and a symbol number in a slot and a scrambling identifier (ID).
