Abstract: 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.

Abstract: The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting acknowledgement/negative ACK (ACK/NACK) in a wireless communication system which supports carrier aggregation, and to an apparatus for the method. A method in which a terminal transmits ACK/NACK in a wireless communication system that supports carrier aggregation comprises the following steps: receiving a physical downlink control channel (PDCCH); receiving a physical downlink shared channel (PDSCH) indicated by the PDCCH; and transmitting ACK/NACK for the PDSCH via a physical uplink control channel (PUCCH). A PUCCH format for transmitting ACK/NACK is selected by taking the number of aggregated carriers into account.

Abstract: A method of receiving, by a base station, a reference signal in a wireless communication system. The method includes transmitting a cell-specific sequence group hopping parameter to a plurality of user equipments (UEs) in a cell. The cell-specific sequence group hopping parameter is used to enable a sequence group hopping for the plurality of UEs in the cell. The method further includes transmitting a UE-specific sequence group hopping parameter to a certain UE, among the plurality of UEs. The UE-specific sequence group hopping parameter is used to disable the sequence group hopping, enabled by the cell-specific SGH parameter, for the certain UE. The method further includes receiving a reference signal, which is generated based on a sequence group number, from the certain UE. The sequence group number is determined by the UE-specific sequence group hopping parameter.
