CROSS REFERENCE TO RELATED APPLICATION
This application claims benefit of priority to Japanese Patent Application No. JP10-361658 filed Dec. 18, 1998, the entire content of which is incorporated by reference herein.
1. Field of the Invention
A more complete appreciation of the present invention and many of the attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description with accompanying drawings, wherein:
FIG. 1 is a block diagram of a mobile wireless apparatus according to an embodiment of the present invention;
FIG. 2 illustrates communication areas covered by a base station wireless apparatus A and by other base station wireless apparatuses according to an embodiment of the present invention;
The present invention will become clear from the following description of the preferred embodiments with reference to the accompanying drawings.
FIG. 1 is a block diagram of a mobile wireless apparatus M according to an embodiment of the present invention. The mobile wireless apparatus M can be employed in a wireless communication system as described in the above related art. Details of the mobile wireless apparatus M are described hereinafter.
Transmission packets transmitted from a base station wireless apparatus are described. The transmission packets are sent one after another through a transmission channel of the base station wireless apparatus. A frame within each transmission packet includes a set of a unique word (UW) and a radio control channel (RCCH) and a set of a common control channel (CCCH) or a user packet channel (UPCH) subsequent to the set of the UW and the RCCH. The UW, which is at the head of each frame is a bit string employed to synchronize frames. The UW is defined as a bit string that has a specific value. The RCCH includes information that indicates the state of radio links and designates a destination mobile wireless apparatus. The RCCH is received by all the mobile wireless apparatuses. The CCCH includes control information; e.g., a call request, and channel information associated with the peripheral base station wireless apparatuses. The CCCH is received by at least one mobile wireless apparatus that has been designated by the RCCH. The UPCH includes data to be transmitted to the mobile wireless apparatus. The UPCH is received by the designated mobile wireless apparatus designated by the RCCH.
