Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A user equipment (UE) for transmitting or receiving signals in a wireless communication system, the UE comprising:
a transceiver; and
a processor,
wherein the processor is configured to control the transceiver to
transmit, to a base station (BS), UE capability information regarding sequence initialization of a demodulation reference signal (DMRS),
receive, from the BS, DMRS configuration information determined based on the UE capability information, and
receive 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 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.
