1. A method for supporting communication, comprising:
adjusting, by an apparatus, at least one moving average window size for demodulation reference signal, (DMRS) subcarriers in at least one resource block of a channel bandwidth; and
applying, by the apparatus, the adjusted at least one moving average window size to the DMRS subcarriers when the at least one resource block is at or beside an edge of the channel bandwidth,
wherein at least one of a first DMRS subcarrier, a second DMRS subcarrier or a third DMRS subcarrier of the DMRS subcarriers is averaged over 5 DMRS subcarriers if one of the adjusted at least one moving average window size is 5,
wherein at least one of a fourth DMRS subcarrier, a fifth DMRS subcarrier or a sixth DMRS subcarrier of the DMRS subcarriers is averaged over 5 DMRS subcarriers, if one of the adjusted at least one moving average window size is 5, and
wherein the at least one resource block comprises a predetermined number of DMRS subcarriers.
