Abstract

The invention provides a radio communication terminal and radio communication control method. A hopping controller (113) selects one hopping pattern from hopping patterns (P1 to PN), reads a hopping frequency series arranged in the selected hopping pattern from a frequency hopping pattern memory (112), and sends the hopping frequency series as a frequency specifying signal in a predetermined cycle to frequency synthesizers (114, 115) through cables. The frequency synthesizers (114, 115) generate respective local oscillation signals of the frequencies specified by the frequency specifying signal and outputs them to mixers (103, 109), respectively. Thus, communication between first and second case portions (K11, K12) by frequency hopping is carried out.
