Abstract
A method for reference signal configuration includes: receiving, by a base station, a plurality of uplink sequences from an uplink channel; performing, by the base station, an optimal combining procedure on the plurality of uplink sequences to output a combined result of the plurality of uplink sequences; determining, by the base station, channel signature information based on the combined result; detecting, by the base station, a plurality of complex signals at peak positions from the plurality of uplink sequences based on the channel signature information: estimating, by the base station, a correlation level based on the plurality of complex signals; and determining a density of the reference signal and MCS based on the correlation level.
