Radio communication system
In a radio communication system a first radio station performs communication by the use of a first radio signal. A second radio station receives a second radio signal which is indistinguishable from the first radio signal. A third radio station is in a radio communication area of the first radio station and a radio communication area of the second radio station. A communication format conversion unit generates a third radio signal by converting a communication format of the second radio signal to a communication format which is distinguishable from the first radio signal, and communicates with the third radio station by the use of the third radio signal.
1. A radio communication system comprising:
a first radio station which transmits data in a first radio format using a first redundant portion;
a second radio station which receives the data, converts the first radio format to a second radio format using a second redundant portion which differs from the first redundant portion in length and transmits the data by use of the second radio format; and
a third radio station which receives the data transmitted from the second radio Station;
wherein the first radio format includes a first radio channel and the second radio format includes a second radio channel being different from the first radio channel.
2. A radio apparatus communicating with both a first radio station and a second radio station, the radio apparatus comprising:
a radio transmitter/receiver which performs communication with the first radio station or the second radio station by use of a radio format; and
a communication format converter which converts the radio format to a fist radio format using a first redundant portion in the case of communicating with the first radio station, and converts the radio format to a second radio format using a second redundant portion which differs from the first redundant portion in length in the case of communicating with the second radio station;
wherein the first radio format includes a first radio channel and the second radio format includes a second radio channel being different from the first radio channel.
3. A radio apparatus communicating with a first radio station via a second radio station, the radio apparatus comprising:
a radio transmitter/receiver which performs communication with the second radio station in a second radio format using a second redundant portion which differs from a first redundant portion in length, the second radio format being different from a first radio format using the first redundant portion used by communication between the first radio station and the second radio station;
wherein the first radio format includes a first radio channel and the second radio format includes a second radio channel being different from the first radio channel.
4. A radio communication method comprising:
transmitting, by a first radio station, data in a first radio format using a first redundant portion;
receiving, by a second radio station, the data, converting the first radio format to a second radio format using a second redundant portion which differs from the first redundant portion in length and transmitting the data by use of the second radio format; and
receiving, by a third radio station, the data transmitted from the second radio station;
wherein the first radio format includes a first radio channel and the second radio format includes a second radio channel being different from the first radio channel.
