Classification: CPC H | IPC H

Claim 10:
11. A base station (BS) for transmitting or receiving signals in a wireless communication system, the BS comprising:
a transceiver; and
a processor,
wherein the processor is configured to control the transceiver to
receive, from a user equipment (UE), UE capability information regarding sequence initialization of a demodulation reference signal (DMRS),
transmit, to the UE, DMRS configuration information determined based on the UE capability information, and
transmit 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.
