Method and base station for receiving reference signal, and method and user equipment for receiving reference signal

摘要

A base station does not transmit any reference signal (RS) for channel measurement in a subframe in which transmission of an RS collides with transmission of a synchronization signal or a broadcast signal or in a resource block including the synchronization signal or the broadcast signal in the subframe. A user equipment assumes that any RS for channel measurement is not transmitted in a subframe or in a resource block when transmission of an RS collides with transmission of a synchronization signal or a broadcast signal in the subframe or in the resource block.

1. A method for receiving, by a user equipment, channel state information reference signals (CSI-RSs) for channel measurement in a wireless communication system, the method comprising:
receiving, by the user equipment, transmission information of the CSI-RSs; and based on the transmission information, receiving, by the user equipment, the CSI-RSs in at least one of plural subframes configured for the CSI-RSs, including a subframe where a synchronization signal or a broadcast signal is present, while assuming none of the CSI-RSs are present in a subframe where a transmission of any CSI-RS of the CSI-RSs collides with a transmission of the synchronization signal or the broadcast signal.
