Description

technical field

[0001] The present invention relates to a radio communication system, a radio communication device, a radio communication method, and a computer program for communicating between a plurality of radio stations in a local area network (LAN) or a personal network (PAN), and in particular to a method for establishing each radio station among them. Communication stations without a master-slave (slave-master) station relationship perform random access operations based on carrier sense multiple access (CSMA) based on carrier detection or media status monitoring in an autonomous distributed manner Radio communication systems, radio A communication device, a radio communication method, and a computer program.

[0002] The invention also relates to a radio communication system, a radio communication device, a radio communication system, a radio communication device, and a radio communication system for establishing an autonomously distributed radio network without the in...

Embodiment Construction

[0105] Embodiments of the present invention will be described below with reference to the drawings.

[0106] According to the present invention, radio waves are used as communication paths, and a network is established with transmission media of a plurality of channels, ie, multi-channel communication stations. The communication is store-and-forward type traffic. More specifically, information is conveyed in packets.

[0107] In known multi-channel communication systems, the channels are the same frequency channel or code channel, and the same channel is usually assigned to a group of communication stations. In contrast, according to a radio communication system of an embodiment of the present invention, a channel is allocated to a communication station per group, thereby reducing the number of communication stations.

[0108] According to an embodiment of the present invention, a packet preamble pattern is created to detect the used channel. If the sending station dynamica...
