Embodiments of the present disclosure relate to a method and apparatus of transmitting a reference signal and a method and apparatus of receiving a reference signal. In one embodiment of the present disclosure, the method of transmitting a reference comprises receiving a reference signal configuration indication, wherein reference signal resources are divided into at least two reference signal groups, and the reference signal configuration indication indicates a reference signal configuration including a reference signal group configuration; and transmitting the reference signal using a reference signal sequence in a reference signal group as indicated by the reference signal group configuration, wherein the reference signal sequence can be multiplexed with another layer or another user in different reference signal groups. With embodiments of the present disclosure, reference signals for different layers or users can be multiplexed in different reference signal groups and thus, more mu-users with unequal allocated bandwidths can be supported without significant channel estimation loss and PAPR loss.
