WIRELESS BASE STATION, USER TERMINAL, AND WIRELESS COMMUNICATION METHOD

WIPO Patent Application WO/2012/067006

A1

Provided are a wireless base station, a user terminal, and a wireless communication method with which it is possible to carry out an accurate measurement in a HetNet even with diverse network configurations. In a heterogeneous network comprising a network configuration wherein a macro-cell and a microcell which is smaller than the macro-cell overlay one another, this wireless communications method: forms the macro-cell; determines a measurement sub-frame which measures CRS, on the basis of the network configuration, with a wireless base station which connects with a macro-terminal which is under the macro-cell; generates a time reference which denotes the measurement sub-frame; transmits a signal containing the time reference and the CRS to the macro-terminal; receives the time reference and the CRS in the macro-terminal; and in the macro-terminal, measures the CRS with the measurement sub-frame denoted in the time reference.
