Abstract

A wireless communication method in which a base station and a wireless terminal communicate, including: an operation at which a first and a second base station transmit, for each beam area, a pilot signal including identification information to identify the base station and the beam area, in a beam pattern; an operation at which the wireless terminal obtains received power of each pilot signal; an operation at which the wireless terminal causes one of the beam areas of the first base station to be a desired wave beam area, and determines two data rates for requiring to the base station: one of the data rates being a first data rate used in a case that interference from the second base station is relatively high and another of the data rates being a second data rate used in a case that the interference from the second base station is relatively low.
