Claim 0:
1. A method, performed by a user equipment (UE), of transmitting or receiving signals in a wireless communication system, the method comprising:
transmitting, to a base station (BS), UE capability information regarding sequence initialization of a demodulation reference signal (DMRS);
receiving, from the BS, DMRS configuration information determined based on the UE capability information; and
receiving the DMRS from the BS based on the DMRS configuration information,
wherein the DMRS is generated based on a sequence initialization parameter, cinit,
wherein the sequence initialization parameter, cinit, is determined based (217×((Nsymbslotns,fμ+l+1)(2NIDλ+1))+2NIDλ+nSCID)mod 2−, 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.
