Abstract

Embodiments described herein related generally to techniques for device discovery for device-to-device (D2D) communications. A user equipment (UE) may receive a transmission probability (e.g., from an evolved Node B (eNB)) for transmission of a discovery medium access control (MAC) protocol data unit (PDU) for D2D communications. The UE may determine a pseudo-random number based on an identifier of the UE, information in the discovery MAC PDU, or information associated with a discovery period. The UE may compare the pseudo-random number with the transmission probability to determine whether to transmit the discovery MAC PDU in the discovery period. Another UE may also determine the pseudo-random number to determine whether the UE is to transmit the discovery MAC PDU in the discovery period. Other embodiments may be described and claimed.

Claims (6)

1 . An apparatus to be employed by a user equipment (UE), the apparatus comprising:

communication circuitry to interface with a radio transceiver to wirelessly communicate with an evolved Node B (eNB); and

control circuitry coupled to the communication circuitry, the control circuitry to:

obtain, via the communication circuitry, a transmission probability from the eNB for transmission of a discovery medium access control (MAC) protocol data unit (PDU) for device-to-device (D2D) communications;

determine a pseudo-random number based on an identifier of the UE, information in the discovery MAC PDU, or information associated with a discovery period; and

compare the pseudo-random number with the transmission probability to determine whether to send the discovery MAC PDU in the discovery period.
