Abstract

In communication method for communicating via a transmission channel to which first communication apparatuses communicating based on a first communication system, second communication apparatuses communicating based on a second communication system, and third communication apparatuses communicating based on a third communication system are connected, a data transmission domain and a notification domain for notifying a data transmission within the data transmission domain are allocated to the first communication apparatuses, the second communication apparatuses, and the third communication apparatuses, respectively. In the communication method, notices of the data transmission for each of the first communication apparatuses, the second communication apparatuses and the third communication apparatuses are transmitted within the notification domain, and the data transmission domain is reallocated in accordance with the notices transmitted from the first, second and third communication apparatuses.

Claims

1. A communication apparatus which is capable of communicating based on a first communication system via a transmission channel to which another communication apparatus communicating based on a second communication system is capable of connecting, comprising;

an integrated circuit;

a housing which includes the integrated circuit;

an indicator which is provided on a second side of the housing;

wherein the integrated circuit comprises;

a transmitter which transmits a first notice including a first notification signal which is rotated by a first phase vector and a second notification signal which is rotated by a second phase vector within a first notification domain;

a detector which detects a second notice transmitted from the another communication apparatus within a second notification domain which is different from the first notification domain; and

a controller which allocates a data transmission which is transmitted from the communication apparatus and a data transmission which is transmitted from the another communication apparatus for at least one of data transmission domains on the basis of the first notice and the second notice.

2. The communication apparatus according to claim 1,

wherein the first notification domain is allocated to the first communication system and the second notification domain is allocated to the second communication system.

3. The communication apparatus according to claim 1,

wherein a transmission order of the first notification signal and the second notification signal corresponds to one of the first communication system and the second communication system.

4. The communication apparatus according to claim 3,

wherein the first notification signal and the second notification signal are transmitted in order of the first notification signal and the second notification signal, the order of those notification signal corresponds to the first communication system.

5. The communication apparatus according to claim 3,

wherein the second notice including the first notification signal and the second notification signal,

wherein the first notification signal and the second notification signal are transmitted in order of the second notification signal and the first notification signal, the order of those notification signal corresponds to the second communication system.

6. The communication apparatus according to claim 1,

wherein the controller allocates the data transmission domain in a predetermined allocation order on the basis of the first notice and the second notice.

7. The communication apparatus according to claim 6, further comprising
