1. A radio relay station comprising:
- a reception processing unit operable to process a radio signal received from a first radio unit and a radio signal received from a second radio unit; and
a control unit operable to control the process of the reception processing unit so that a first reception period in which a first radio signal is receivable from the first radio unit and a second reception period in which a second radio signal is receivable from the second radio unit, using a frequency different from that of the first radio signal, are at least partially overlapped.

Abstract
A receiving process is controlled so that a first reception period during which a radio signal may be received from a first radio unit and a second reception period during which a radio signal may be received from the first radio unit using a frequency different from a frequency used for the radio signal received from the first radio unit are at least partially overlapped.

13. A radio terminal comprising:
-
a transmission/reception processing unit operable to transmit and receive a radio signal to/from a radio relay station; and a control unit operable to control the process of the transmission/reception processing unit so that a radio frame based on a synchronization signal periodically transmitted from the radio relay station includes a first reception period during which a radio signal including the synchronization signal is receivable from the radio relay station, a transmission period during which a radio signal is transmittable to the radio relay station after the lapse of a non-communication period subsequent to the first reception period, and a second reception period during which a radio signal is receivable from the radio relay station after the lapse of a non-communication period subsequent to the transmission period.
