Communication apparatus and method
View Patent ↗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.
1. 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.
2. The communication apparatus according to claim 1 ,
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.
3. The communication apparatus according to claim 1 ,
wherein the circuitry schedules the transmission of the WUR Beacon frame a determined time after the transmission of the 802.11 Beacon frame.
4. The communication apparatus according to claim 3 ,
wherein the determined time is a Short Interframe Space (SIFS).
5. The communication apparatus according to claim 3 ,
wherein the determined time is less than a Short Interframe Space (SIFS).
6. The communication apparatus according to claim 1 ,
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.
7. 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.
8. The communication method according to claim 7 ,
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.
9. The communication method according to claim 7 ,
wherein the transmission of the WUR Beacon frame is scheduled a determined time after the transmission of the 802.11 Beacon frame.
10. The communication method according to claim 9 ,
wherein the determined time is a Short Interframe Space (SIFS).
11. The communication method according to claim 9 ,
wherein the determined time is less than a Short Interframe Space (SIFS).
12. The communication method according to claim 7 ,
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.
