Abstract

The present disclosure provides a transmission apparatus that comprises a first payload generator configured to generate payload of a packet of a first signal type; a second payload generator configured to generate payload of a packet of a second signal type; a packet scheduler that controls the transmission timings of the first and the second packet; and a transmitter which, in operation, transmits, under the timing control of the packet scheduler, the packet of the first signal type followed by the packet of the second signal type.

Claims

1-10. -10. (canceled)

11. A communication apparatus comprising:

circuitry which, in operation, schedules a 802.11 Beacon frame and a WUR Beacon frame wherein the circuitry schedules a transmission of the 802.11 Beacon frame followed by a transmission of the WUR Beacon frame, and

a transmitter which in operation, transmits the 802.11 Beacon frame and the WUR Beacon frame.

12. The communication apparatus according to claim 11,

wherein the WUR Beacon frame includes a duration field which indicates a time period, and sets a Network Allocation Vector (NAV) for the time period.

13. The communication apparatus according to claim 11,

wherein the circuitry schedules the transmission of the WUR Beacon frame a determined time after the transmission of the 802.11 Beacon frame.

14. The communication apparatus according to claim 13,

wherein the determined time is a Short Interframe Space (SIFS).

15. The communication apparatus according to claim 13,

wherein the determined time is less than a Short Interframe Space (SIFS).

16. The communication apparatus according to claim 11,

wherein the circuitry does not schedule a transmission of any other frames between the transmission of the 802.11 Beacon frame and the transmission of the WUR Beacon frame.

17. A communication method for wireless station comprising:

scheduling a 802.11 Beacon frame and a WUR Beacon frame wherein a transmission of the 802.11 Beacon frame is followed by a transmission of the WUR Beacon frame, and transmitting the 802.11 Beacon frame and the WUR Beacon frame.

18. The communication method according to claim 17,

wherein the WUR Beacon frame includes a duration field which indicates a time period, and sets a Network Allocation Vector (NAV) for the time period.

19. The communication method according to claim 17,

wherein the transmission of the WUR Beacon frame is scheduled a determined time after the transmission of the 802.11 Beacon frame.

20. The communication method according to claim 19,

wherein the determined time is a Short Interframe Space (SIFS).

21. The communication method according to claim 19,

wherein the determined time is less than a Short Interframe Space (SIFS).

22. The communication method according to claim 17,

wherein a transmission of any other frames are not scheduled between the transmission of the 802.11 Beacon and the transmission of the WUR Beacon frame.
