Classification: CPC H | IPC H

Claim 4:
5. A method, performed by a base station (BS), of transmitting or receiving signals in a wireless communication system, the method comprising:
receiving, from a user equipment (UE), UE capability information regarding sequence initialization of a demodulation reference signal (DMRS);
transmitting, to the UE, DMRS configuration information determined based on the UE capability information; and
transmitting the DMRS to the UE,
wherein the DMRS is generated based on a sequence initialization parameter, cinit,
wherein the sequence initialization parameter, cinit, is determined based on (217×((Nsymbslotns,fμ+l+1)(2NIDλ+1))+2NIDλ+nSCID)mod 231, a number of symbols per slot, Nsymbslot, a slot number within a frame, ns,fμ, a symbol number within a slot, l, a code division multiplexing (CDM) group identifier, λ, a virtual cell identifier, NIDλ, and a value indicated by downlink control information, nSCID, and
wherein the CDM group identifier, λ, is included in the DMRS configuration information.
