Abstract

A base station apparatus corresponding to a first base station apparatus of base station apparatuses and connected to terminal apparatuses, first base station apparatus transmitting and receiving first packets with respect to a second base station apparatus corresponding to another of base station apparatuses and transmitting and receiving second packets with respect to terminal apparatuses, first base station apparatus transmits a third packet to second base station apparatus, third packet corresponding to one of first packets to be transmitted from first base station apparatus and including a first data item, second base station apparatus recognizing by first data item that first base station apparatus is one of base station apparatuses, third packet being used through an authentication process or an association process for connecting in wireless first base station apparatus to second base station apparatus.

Claims

1. A wireless communication apparatus having a relay function, configured for:

(a) receiving a beacon frame transmitted from another wireless communication apparatus having a relay function;

(b) transmitting, to the another wireless communication apparatus, an authentication request frame used in an authentication process;

(c) receiving an authentication response frame used in the authentication process and transmitted from the another wireless communication apparatus;

(d) transmitting, to the another wireless communication apparatus, an association request frame used in an association process;

(e) receiving an association response frame used in the association process and transmitted from the another wireless communication apparatus; and

(f) associating with the another wireless communication apparatus if the authentication process and the association process succeed;

the wireless communication apparatus comprising;

a unit configured to insert a data item into one or more fields which are included in at least one of the authentication request frame and the association request frame, the data item indicating the wireless communication apparatus has a relay function; and

a transmitter unit configured to transmit at least one of the authentication request frame and the association request frame including the data item, in the authentication process and/or association process.

2. The wireless communication apparatus according to claim 1, wherein the wireless communication apparatus is configured for communicating with the another wireless communication apparatus and terminals arranged to associate with the wireless communication apparatus using a same channel.

3. The wireless communication apparatus according to claim 1, further comprising:

a receiver unit configured to receive a first address table containing addresses of terminals arranged to associate with the another wireless communication apparatus.

4. The wireless communication apparatus according to claim 3, further comprising:

a unit configured to relay a data frame addressed to a terminal arranged to associate with the another wireless communication apparatus by using the first address table.

5. The wireless communication apparatus according to claim 1, further comprising:

a second transmitter unit configured to transmit, to the another wireless communication apparatus, a second address table containing addresses of terminals arranged to associate with the wireless communication apparatus.

6. The wireless communication apparatus according to claim 1, further comprising:

a second receiver unit configured to receive a frame of a plurality of frames including (a) a first frame transmitted from a terminal arranged to associate with the wireless communication apparatus, (b) a second frame used in communication among the another wireless communication apparatus and terminals arranged to associate with the another wireless communication apparatus, and (c) a third frame used in communication among the terminals arranged to associate with the another wireless communication apparatuses; and

a transmission controlling unit configured (a) to suppress, when the frame received is the first frame, transmission of frames with respect to the another wireless communication apparatus and frames with respect to terminals arranged to associate with the wireless communication apparatus, and (b) not to suppress the transmission when the frame received is the second or the third frame.

7. A terminal arranged to associate with the apparatus according to claim 1, comprising:

a receiver unit configured to receive a frame of a plurality of frames including (a) a first frame which is not addressed to the terminal and is transmitted from the wireless communication apparatus or another terminal arranged to associate with the wireless communication apparatus, (b) a second frame used in communication among the another wireless communication apparatus and terminals arranged to associate with the another wireless communication apparatus, and (c) a third frame used in communication among the terminals arranged to associate with the another wireless communication apparatuses; and

a transmission controlling unit configured (a) to suppress transmission of frames when the frame received is the first frame, and (b) not to suppress the transmission when the frame received is the second or the third frame.

8. The wireless communication apparatus according to claim 6, wherein the transmission controlling unit suppresses the transmission for a predetermined time.

9. The wireless communication apparatus according to claim 1, further comprising:

an antenna; and

a receiver unit configured to receive the beacon frame, the authentication response frame, and the association response frame through the antenna,

wherein the transmitter unit is configured to transmit the authentication request frame and the association request frame through the antenna.

10. A wireless communication apparatus having a relay function, configured for:

(a) receiving a beacon frame transmitted from another wireless communication apparatus having a relay function;

(b) transmitting, to the another wireless communication apparatus, an authentication request frame used in an authentication process;

(c) receiving an authentication response frame used in the authentication process and transmitted from the another wireless communication apparatus;

(d) transmitting, to the another wireless communication apparatus, an association request frame used in an association process;

(e) receiving an association response frame used in the association process and transmitted from the another wireless communication apparatus; and

(f) associating with the another wireless communication apparatus if the authentication process and the association process succeed;

the wireless communication apparatus comprising;

a unit configured to insert a data item into one or more fields which are included in a frame used in at least one of the authentication process and association process, the data item indicating the wireless communication apparatus has a relay function; and

a transmitter unit configured to transmit the frame including the data item, in the authentication process or association process.

11. The wireless communication apparatus according to claim 10, further comprising:

an antenna; and

a receiver unit configured to receive the beacon frame, the authentication response frame, and the association response frame through the antenna,

wherein the transmitter unit is configured to transmit the authentication request frame, the association request frame, and the frame including the data item through the antenna.
