Abstract

Examples of a communication device and methods for synched distributed advertisement for device-to-device are generally described herein. In some embodiments, a method can include transmitting, from a first device of a publishing group, at a group publishing beacon interval (T), a first publishing beacon (PB) including social information of the first device and social information of (N−1) other devices, wherein the group publishing beacon interval (T) represents a preset interval of time between each successive publishing beacon transmission of the publishing group, and wherein the first publishing beacon and the each successive publishing beacon includes a first value representative of the group publishing beacon interval.

Claims

1. A method for synched distributed advertisement among peer-to-peer wireless devices, the method comprising:

transmitting, from a first device of a publishing group, at the beginning or end of a group publishing beacon interval (T), a first publishing beacon (PB) including social information of the first device and social information of (N−

1) other devices;

adding an (N+1) device to the group;

transmitting a second publishing beacon from the first device;

transmitting a subsequent publishing beacon from the (N+1) device at an interval of time subsequent to transmission of the second publishing beacon, wherein the interval of time is N*T or 2*N*T, and wherein T is the group publishing beacon interval (T);

wherein the group publishing beacon interval (T) represents an interval of time between each successive publishing beacon transmission of the publishing group; and

wherein the first publishing beacon and the each successive publishing beacon includes a first value representative of the group publishing beacon interval (T).

2. The method of claim 1, wherein N is an integer value greater than zero;

wherein N represents the number of devices in the publishing group when the first publishing beacon is transmitted; and

wherein the (N−

1) other devices belong to the publishing group.

3. The method of claim 1, wherein the adding n (N+1) device includes receiving a join request from an (N+1) device, wherein the (N+1) device does not belong to the publishing group when the join request is received.

4. The method of claim 3, wherein receiving the join request includes receiving the join request during a publishing group window prior to transmitting the second publishing beacon from the first device.

5. The method of claim 4, wherein receiving the join request includes receiving social information of the (N+1) device.

6. The method of claim 5, wherein the second publishing beacon includes the social information of the (N+1) device.

7. The method of claim 6, wherein receiving the join request includes incrementing the number of devices in the publishing group to account for the (N+1) device.

8. The method of claim 1, wherein the interval of time is 2*N*T;

and

wherein the method includes receiving (N−

1) publishing beacons from the (N−

1) other devices at the (N+1) device and the first device after transmission of the second publishing beacon, wherein each of the (N−

1) publishing beacons include the social information of the (N+1) device.

9. The method of claim 8, including incrementing the number of devices in the publishing group after transmission of the second publishing beacon from the first device and after subsequently receiving the (N−

1) publishing beacons from the (N−

1) other devices.

10. The method of claim 1, wherein the interval of time is 2*N*T;

and wherein the method includes transmitting subsequent join requests to each of the (N−

1) other devices during a publishing group window associated with each of the (N−

1) other devices.

11. The method of claim 1, wherein the each successive publishing beacon includes a second value representative of the number of devices in the publishing group.

12. The method of claim 1, wherein the each successive publishing beacon includes a third value representative of a duration of a publishing group window, wherein the publishing group window begins prior to a transmission of a publishing beacon from the first device or a transmission of a publishing beacon from one of the (N−

1) other devices.

13. A wireless communication device configured for synched distributed advertisement within a publishing group, the wireless communication device comprising:

an transceiver configured to receive a first publishing beacon from a publishing group including a number of other wireless devices, and to transmit a first join request during a publishing group window of one of the number of other wireless devices using information received in the first publishing beacon, wherein the join request includes social information of the wireless communication device, and wherein a value representative of a publishing beacon interval (T) between publishing beacons of the publishing group is included in the first publishing beacon;

wherein the transceiver is configured to receive a second publishing beacon from the one of the number of other wireless devices wherein the second publishing beacon includes the social information of the wireless communication device;

wherein the transceiver is configured to transmit a third publishing beacon at a first time interval after receiving the second publishing beacon; and

wherein the first time interval is N*T or 2*N*T, where N represents the number of devices in the publishing group when the first publishing beacon was received.

14. A wireless communication device configured for synched distributed advertisement within a publishing group, the wireless communication device comprising:

a processor;

memory coupled to the processor;

an transceiver configured for providing wireless communications of information stored in, and retrieved from, the memory;

wherein the transceiver is configured to receive a first publishing beacon from a publishing group including a number of other wireless devices, and to transmit a first join request during a publishing group window of one of the number of other wireless devices using information received in the first publishing beacon, wherein the join request includes social information of the wireless communication device, wherein the memory is configured to store the social information of the wireless communication device, and wherein a value representative of a publishing beacon interval (T) between publishing beacons of the publishing group is included in the first publishing beacon;

wherein the transceiver is configured to receive a second publishing beacon from the one of the number of other wireless devices, the second publishing beacon including the social information of the wireless communication device;

wherein the transceiver is configured to transmit a third publishing beacon at a first time interval after receiving the second publishing beacon; and

wherein the first time interval is N*T or 2*N*T, where N represents the number of devices in the publishing group when the first publishing beacon was received.

15. A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors to perform operations for synched distributed advertisement, the operations configure to:

transmit, from a first device of a publishing group, at the beginning or end of a group publishing beacon interval (T), a first publishing beacon (PB) including social information of the first device and social information of (N−

1) other devices;

add an (N+1) device to the group;

transmit a second publishing beacon from the first device;

transmit a subsequent publishing beacon from the (N+1) device at an interval of time subsequent to transmission of the second publishing beacon, wherein the interval of time is N*T or 2*N*T, and wherein T is the group publishing beacon interval (T);
