Kind Code:
B2
Abstract:
To provide a method and an apparatus for transmitting a reference signal, and a method and an apparatus for receiving the reference signal.SOLUTION: In a method for transmitting a reference signal in one embodiment of the present disclosure, a reference signal resource is divided into at least two reference signal groups. The method includes the steps of: receiving a reference signal configuration indication indicating a reference signal configuration including a reference signal group configuration; and transmitting a reference signal by using a reference signal sequence in the reference signal group indicated by the reference signal group configuration, the reference signal sequence capable of being multiplexed with another layer or another user in a different reference signal group. In the embodiment of the present disclosure, the reference signal for the different layer or user can be multiplexed with the different reference signal group, and thus a larger number of mu-users having ununiform band width can be supported without significant channel estimation loss and PAPR loss.SELECTED DRAWING: Figure 5
