In order to transmit a paging to a user terminal with high quality, transmit a CSI-RS effectively and perform UL HARQ efficiently in HetNet, the present invention provides a radio communication method having the steps of: a micro base station which is arranged in a macro cell and forms a smaller micro cell than the macro cell, transmitting, to a user terminal, a signal having a CSI-RS subframe including a CSI-RS and a paging subframe including modification notification information indicating modification in system information and a control signal indicating not to measure a CSI-RS when the CSI-RS subframe and the paging subframe collide with each other; and the user terminal determining a CSI-RS subframe to measure the CSI-RS based on the control signal when the CSI-RS subframe and the paging subframe collide with each other.
A user terminal for receiving a CSI-RS (Channel State Information-Reference Signal) periodically transmitted in a CSI-RS subframe and a paging transmitted in at least one of paging subframes, the user terminal comprising:
A radio communication method in a user terminal receiving a CSI-RS (Channel State Information-Reference Signal) periodically transmitted in a CSI-RS subframe and a paging transmitted in at least one of paging subframes, the radio communication method comprising the steps of:
A radio communication system having a user terminal that receives a CSI-RS (Channel State Information-Reference Signal) periodically transmitted in a CSI-RS subframe and a paging transmitted in at least one of paging subframes, comprising:
