[0028] (a) About WiMAX

[0029] [About wireless frame]

[0030] In WiMAX, as an example of a communication method, a communication method based on an Orthogonal Frequency Division Multiple Access (OFDMA: Orthogonal Frequency Division Multiplexing) method is adopted.

[0031] In the WiMAX system used in this embodiment, a radio frame is defined by a time axis divided by OFDMA symbol time and a frequency axis divided by subchannels (logical sets of subcarriers having orthogonality). For example, in allocating radio frames, the base sta...

Abstract

In order to reduce possible interference among different communication systems, a wireless communication apparatus includes: a first signal communicating unit that receives a first signal of a first wireless communication system or transmits, based on allocation information of a wireless communication resource which information is transmitted in a predetermined cycle, the first signal of the first wireless communication system; a second signal communicating unit that receives or transmits a second signal of a second wireless communication system different from the first wireless communication system; and a controller that restricts the first signal communicating unit to transmit the first signal of the first wireless communication system using a wireless communication resource allocated by the allocation information while the second signal communicating unit transmits or receives the second signal.

Description

technical field [0001] The present invention relates to a wireless communication device and a wireless communication method compatible with a plurality of different wireless communication systems. Background technique [0002] For example, a mobile terminal corresponding to a wide-area wireless communication system such as WiMAX (Worldwide interoperability for Microwave Access) standardized by IEEE (Institute of Electrical and Electronic Engineers: Institute of Electrical and Electronics Engineers) is equipped with Bluetooth(R) and WLAN (Wireless Local Area Network: Wireless Local Area Network) functions of short-range wireless communication systems, thereby providing multiple functions with a single mobile terminal. [0003] On the other hand, the frequency band used by WiMAX and the frequency band used by Bluetooth or WLAN overlap around 2.4 GHz. That is, a plurality of communication systems compete to use the same frequency. Therefore, when a mobile terminal supporting ...
