Abstract
A method and user equipment for receiving channel status information-reference signals (CSI-RSs) from a base station (BS) in a wireless communication system, are discussed. The method includes receiving, through a higher layer, configuration about two or more CSI-RS; and receiving, from the BS, the CSI-RSs based on the configuration, wherein, when the configuration includes an indicator related to antenna ports of the two or more CSI-RS, the CSI-RSs are received on the assumption that the antenna ports for two or more CSI-RS resources are same.
Claims6
A method for receiving channel status information-reference signals (CSI-RSs) from a base station (BS) by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, through a higher layer, configuration about two or more CSI-RSs,
- wherein the configuration includes information about two or more antenna ports on which the two or more CSI-RSs are transmitted from the BS;
- and
- receiving, from the BS, the two or more CSI-RSs based on the configuration,
- wherein, based on the configuration including an indicator related to antenna ports of the two or more CSI-RSs, the two or more CSI-RSs are received on the assumption that the two or more antenna ports on which the two or more CSI-RSs are transmitted from the BS are of a same antenna.
A user equipment (UE) in a wireless communication system, the UE comprising:
- a RF (radio frequency) module;
- and
- a processor connected with the RF module,
- wherein the processor is configured to:
- receive, through a higher layer, configuration about two or more channel status information-reference signals (CSI-RSs), wherein the configuration includes information about antenna ports on which the two or more CSI-RSs are transmitted from a base station (BS), and
- receive, from the BS, the two or more CSI-RSs based on the configuration,
- wherein, based on the configuration including an indicator related to antenna ports of the two or more CSI-RSs, the two or more CSI-RSs are received on the assumption that the antenna ports on which the two or more CSI-RSs are transmitted from the BS are of a same antenna.
