Abstract

The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate beyond a 4G communication system such as LTE. To this end, a base station using a large-scale antenna transmits, to a terminal, reference signal resource configuration information including multiple pieces of reference signal configuration information and reference signal port information, for transmission of a reference signal, and transmits the reference signal to the terminal using some or all of channel measurement resources indicated by the multiple pieces of reference signal configuration information and the reference signal port information included in the reference signal resource configuration information. In this case, the channel measurement resources may correspond to antenna ports, the number of which is indicated by a combination of the multiple pieces of reference signal configuration information and the reference signal port information.

Claims

transmitting, to a user equipment (UE), configuration information on at least one reference signal resource, the configuration information including information on the at least one reference signal resource and information on at least one reference signal port per a resource; and

transmitting, to the UE, reference signals through the at least one reference signal resource and the at least one reference signal port,

wherein a number of the at least one reference signal port is determined based on information on the at least one reference signal resource and the information on the at least one reference signal port per the resource.

2. The method of claim 1, wherein the information on the at least one reference signal resource is related to a number of the at least one reference signal resource, and wherein the information on the at least one reference signal port per the resource is related to a number of antenna ports corresponding to each one of the at least one reference signal resource.

3. The method of claim 2, wherein the number of the at least one reference signal per the resource is determined by a product of the number of the at least one reference signal resource and the number of the antenna ports corresponding to the each one of the at least one reference signal resource.

4. The method of claim 2, wherein each of the number of the antenna ports corresponding to the each one of the at least one reference signal resource is configured with same number.

17. The method of claim 2, wherein the number of the antenna ports is more than eight antenna ports.

5. An evolved nodeB (eNB) for transmitting a reference signal in a wireless communication system, the eNB comprising:

a transceiver; and

a processor configured to control the transceiver to;

transmit, to a user equipment (UE), configuration information on at least one reference signal resource, the configuration information including information on the at least one reference signal resource and information on at least one reference signal port per a resource, and

transmit, to the UE, reference signals through the at least one reference signal resource and the at least one reference signal port,

wherein a number of the at least one reference signal port is determined based on information on the at least one reference signal resource and the information on the at least one reference signal port per the resource.

6. The eNB of claim 5, wherein the information on the at least one reference signal resource is related to a number of the at least one reference signal resource, and wherein the information on the at least one reference signal port per the resource is related to a number of antenna ports corresponding to each one of the at least one reference signal resource.

7. The eNB of claim 6, wherein the number of the at least one reference signal port per the resource is determined by a product of the number of the at least one reference signal resource and the number of the antenna ports corresponding to the each one of the at least one reference signal resource.
