Abstract
In accordance with an example embodiment of the present invention, a method comprises identifying at least one beacon opportunity at a wireless network device; selecting a beacon channel from a beacon slot that is a flexibly allocated frequency resource; and transmitting at least one beacon signal in the selected beacon channel multiplexed in a beacon frame during the identified beacon opportunity.

1-43. (canceled)
A method, comprising
- identifying at least one beacon opportunity at a wireless network device;
- selecting a beacon channel from a beacon slot that is a flexibly allocated frequency resource;
- and
- transmitting at least one beacon signal in the selected beacon channel multiplexed in an orthogonal frequency-division multiplexing (OFDM) beacon frame during the identified beacon opportunity.
A method, comprising
- identifying a beacon opportunity at a network device;
- selecting a beacon slot that is a flexibly allocated frequency resource;
- receiving at least one orthogonal frequency division multiplexing (OFDM) beacon frame from at least one neighbor wireless device during the identified beacon opportunity;
- and
- determining a presence of at least one neighbor D2D device from the at least one received OFDM beacon frame.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code the at least one memory and the computer program code configured to identify at least one beacon opportunity at a wireless network device;
- and
- select a beacon channel from a beacon slot that is flexibly allocated in a frequency resource;
- and
- transmit at least one beacon signal in the selected beacon channel multiplexed in an OFDM beacon frame during the identified beacon opportunity.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code
- the at least one memory and the computer program code configured to identify a beacon opportunity at a network device;
- select a beacon slot that is a frequency resource for beaconing purpose;
- receive at least one OFDM beacon frame from at least one neighbor wireless device;
- and
- determine a presence of at least one neighbor D2D device from the at least one received OFDM beacon frame.
A computer program product comprising a program code stored in a computer readable medium configured to:
- identify at least one beacon opportunity at a wireless network device;
- select a beacon channel from a beacon slot that is a flexibly allocated frequency resource for beaconing;
- and
- transmit at least one beacon signal in the selected beacon channel multiplexed into an OFDM beacon frame during the identified beacon opportunity.
