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, downlink signals in a wireless communication system, the method comprising:
receiving, by the user equipment, a synchronization signal over a predetermined number of center resource blocks among a plurality of resource blocks forming a downlink frequency bandwidth at every 5 subframes; receiving, by the user equipment, channel state information reference signal (CSI-RS) configuration information; and based on the CSI-RS configuration information, receiving, by the user equipment, CSI-RSs over the downlink frequency bandwidth in at least one of plural subframes configured for the CSI-RSs, including a subframe where the synchronization signal is present, while assuming none of the CSI-RSs corresponding to the CSI-RS configuration information are present in a subframe where a reception of any CSI-RS of the CSI-RSs collides with a reception of the synchronization signal.
