User terminal, radio base station, radio communication method and radio communication system

A radio base station comprising:

• a transmission section that transmits a detection/measurement signal including a synchronization signal and a channel state measurement signal, and information including a first identifier that relates to the synchronization signal and a second identifier that relates to a channel state measurement signal corresponding to the synchronization signal, to a user terminal, wherein the transmission section further transmits a plurality of pieces of information that include a combination of the first identifier and the second identifier;
• and
• a receiving section that receives, from the user terminal, a measurement result of the channel state measurement signal identified by the second identifier, based on the synchronization signal corresponding to the first identifier, wherein the measurement result is based on the channel state measurement signal that is identified by the second identifier of a given combination, based on the synchronization signal corresponding to the first identifier of the given combination.

A radio communication system comprising a radio base station that foul's a cell and a user terminal that is able to communicate with the radio base station, wherein the user terminal comprises:

• a receiving section that receives a detection/measurement signal including a synchronization signal and a channel state measurement signal, and information including a first identifier that relates to the synchronization signal and a second identifier that relates to a channel state measurement signal corresponding to the synchronization signal, wherein the receiving section further receives a plurality of pieces of information that include a combination of the first identifier and the second identifier;
• and
• a control section that controls to measure the channel state measurement signal identified by the second identifier based on the synchronization signal corresponding to the first identifier, wherein the control section further controls to measure the channel state measurement signal that is identified by the second identifier of a given combination, based on the synchronization signal corresponding to the first identifier of the given combination.
