Method and apparatus for transmitting reference signal in wireless communication system
A communication method and a system for converging a fifth generation (5G) communication system for supporting higher data rates beyond a fourth generation (4G) system with an internet of things (IoT) technology are provided, which may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method and an apparatus for transmitting a reference signal are provided. The method includes receiving, from a base station, a first parameter and a second parameter associated with a sound reference signal (SRS) by higher layer signaling, identifying a bandwidth for the SRS based on the first parameter and the second parameter, and transmitting, to the base station, the SRS based on the identified bandwidth for the SRS.

wherein the first bandwidth set does not include a part of the second bandwidth set less than 272 RB.
2. The method of claim 1 , further comprising:
receiving, from the base station, offset information by higher layer signaling, the offset information being based on a common resource block; and

13. A base station in a wireless communication system, the base station comprising:
a transceiver; and
at least one processor operably connected to the transceiver and configured to control the transceiver to:
transmit, to a user equipment (UE), a first parameter and a second parameter by higher layer signaling, and
receive, from the UE, sound reference signal (SRS) based on a bandwidth for the SRS, the bandwidth being identified based on the first parameter and the second parameter,
wherein the first parameter and the second parameter comprise UE-specific parameters,
wherein a first value of the first parameter indicates a first bandwidth set not including 272 resource blocks (RB) and a second value of the first parameter indicates a second bandwidth set including 272 RB in a predetermined table, and
wherein the first bandwidth set does not include a part of the second bandwidth set less than 272 RB.
14. The base station of claim 13 ,
wherein the at least one processor is further configured to control the transceiver to transmit, to the UE, offset information by higher layer signaling, the offset information being based on a common resource block, and
wherein the SRS is received based on the bandwidth and a starting point for the bandwidth, the starting point being identified based on the offset information.
15. The base station of claim 13 , wherein the bandwidth for the SRS includes up to 272 resource blocks (RB).
16. The base station of claim 13 , wherein the predetermined table comprises:
B SRS = 0
B SRS = 1
B SRS = 2
B SRS = 3
