INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Methods, devices, and computer program products for transmitting and receiving discovery and paging messages are described herein. In one aspect, an apparatus operable in a wireless communication system includes a receiver and transmitter. The receiver receives a registration packet from a first device. The registration packet indicates interest in a service provided by another device in a wireless communications network. The receiver further receives a discovery packet from a second device during a first discovery interval of a plurality of discovery intervals. The discovery packet advertises a service provided by the second device, and the plurality of discovery intervals include recurring time intervals when a plurality of devices are configured to transmit and receive discovery packets in the wireless communications network. The transmitter transmits a notification packet configured to enable the first device and the second device to communicate directly. ## Claims ### Claim 1 A method of wireless communication performed by an apparatus, the method comprising: receiving a registration packet from a first device, the registration packet indicating interest in a service provided by another device in a wireless communications network; receiving a discovery packet from a second device during a first discovery interval of a plurality of discovery intervals, the discovery packet advertising a service provided by the second device, the plurality of discovery intervals comprising recurring time intervals when a plurality of devices are configured to transmit and receive discovery packets in the wireless communications network; and transmitting a notification packet configured to enable the first device and the second device to communicate directly. ### Claim 2 (depends on 1) The method of claim 1, further comprising transmitting a power-save message configured to instruct the first device to enter a power-save mode. ### Claim 3 (depends on 1) The method of claim 1, further comprising transmitting an awaken message configured to instruct the first device to leave a power-save mode. ### Claim 4 (depends on 3) The method of claim 3, wherein the awaken message comprises a traffic indication message. ### Claim 5 (depends on 1) The method of claim 1, wherein said transmitting the notification packet comprises transmitting the notification packet to the first device. ### Claim 6 (depends on 5) The method of claim 5, wherein the notification packet comprises a page forward frame configured to forward the discovery packet received from the second device. ### Claim 7 (depends on 1) The method of claim 1, wherein said transmitting the notification packet comprises transmitting the notification packet to the second device. ### Claim 8 (depends on 7) The method of claim 7, further comprising transmitting the notification packet during a first paging interval of a plurality of paging intervals, the notification packet comprising a paging packet indicating interest by the first device in the service provided by the second device, the plurality of paging intervals comprising recurring time intervals when the plurality of devices are configured to transmit and receive paging packets in the wireless communications network, the plurality of paging intervals not overlapping the plurality of discovery intervals. ### Claim 9 An apparatus operable in a wireless communication system comprising: a receiver configured to receive a registration packet from a first device, the registration packet indicating interest in a service provided by another device in a wireless communications network, and receive a discovery packet from a second device during a first discovery interval of a plurality of discovery intervals, the discovery packet advertising a service provided by the second device, the plurality of discovery intervals comprising recurring time intervals when a plurality of devices are configured to transmit and receive discovery packets in the wireless communications network; and a transmitter configured to transmit a notification packet configured to enable the first device and the second device to communicate directly. ### Claim 10 (depends on 9) The apparatus of claim 9, wherein the transmitter is further configured to transmit a power-save message configured to instruct the first device to enter a power-save mode. ### Claim 11 (depends on 9) The apparatus of claim 9, wherein the transmitter is further configured to transmit an awaken message configured to instruct the first device to leave a power-save mode. ### Claim 12 (depends on 11) The apparatus of claim 11, wherein the awaken message comprises a traffic indication message. ### Claim 13 (depends on 9) The apparatus of claim 9, wherein the transmitter is configured to transmit the notification packet to the first device. ### Claim 14 (depends on 13) The apparatus of claim 13, wherein the notification packet comprises a page forward frame configured to forward the discovery packet received from the second device. ### Claim 15 (depends on 9) The apparatus of claim 9, wherein the transmitter is configured to transmit the notification packet to the second device. ### Claim 16 (depends on 15) The apparatus of claim 15, wherein the transmitter is further configured to transmit the notification packet during a first paging interval of a plurality of paging intervals, the notification packet comprising a paging packet indicating interest by the first device in the service provided by the second device, the plurality of paging intervals comprising recurring time intervals when the plurality of devices are configured to transmit and receive paging packets in the wireless communications network, the plurality of paging intervals not overlapping the plurality of discovery intervals. ### Claim 17 An apparatus operable in a wireless communication system comprising: means for receiving a registration packet from a first device, the registration packet indicating interest in a service provided by another device in a wireless communications network; means for receiving a discovery packet from a second device during a first discovery interval of a plurality of discovery intervals, the discovery packet advertising a service provided by the second device, the plurality of discovery intervals comprising recurring time intervals when a plurality of devices are configured to transmit and receive discovery packets in the wireless communications network; and means for transmitting a notification packet configured to enable the first device and the second device to communicate directly. ### Claim 18 A non-transitory computer-readable medium comprising instructions that when executed cause an apparatus to: receive a registration packet from a first device, the registration packet indicating interest in a service provided by another device in a wireless communications network; receive a discovery packet from a second device during a first discovery interval of a plurality of discovery intervals, the discovery packet advertising a service provided by the second device, the plurality of discovery intervals comprising recurring time intervals when a plurality of devices are configured to transmit and receive discovery packets in the wireless communications network; and transmit a notification packet configured to enable the first device and the second device to communicate directly.
