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.

Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may identify a jitter pattern for a wakeup message. A station may listen using a wakeup radio for a wakeup message during wakeup listening periods according to the identified jitter pattern. A station may receive a preamble having a first bandwidth and a wakeup message having a second bandwidth. An AP may transmit an identifier key to a station, and the station may determine a rotating identifier associated with the AP based on the received identifier key. The station may receive a wakeup message from the AP, compare a sender identifier with the rotating identifier, and power on a second radio. A station may also receive a wakeup message that includes an indication of which station are to be activated.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request to establish a multicast session. The request may identify a multicast service session including a multicast quality of service flow. The UE may receive, from a base station wirelessly communicating with the UE, an indication of communication resources for the UE to use to receive multicast packets of the multicast service session from a content provider via a tunnel between a first network node and the base station. The tunnel may be established for the multicast service session based on identifying that the multicast service session lacks an existing tunnel between the first network node and the base station. The UE may identify a discontinuous reception (DRX) cycle for the multicast service session, and receive the multicast packets from the base station according to the indicated communication resources and the identified DRX cycle.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may support multicast transmissions from a base station to multiple user equipments (UEs). Each UE may have uplink resources allocated for providing feedback to the base station regarding multicast transmissions. For example, a UE may not successfully decode one or more frames of a multicast transmission. When a UE does not successfully decode the one or more frames, the UE may transmit negative acknowledgment (NACK) feedback indicating the one or more frames that were not successfully received. A serving base station may store frames within a buffer for a transmission window and retransmit each of the frames indicated within the NACK feedback from the stored frames. In some cases, the serving base station may not retransmit frames that were not indicated within the NACK feedback (e.g., frames that may have been received successfully by the UE).

Abstract: Methods, systems, and devices for wireless communication are described. Stations within a neighborhood awareness network (NAN) may determine when to transmit synchronization beacons during a wake-up time based on some priority (e.g., stations with more recent clock updates or earlier time stamps, stations communicating with a larger number of peers or associated with a larger number of NAN device links (NDLs), etc. may transmit beacons earlier in a wake-up window or with a higher probability). Other stations within the NAN may maintain clock synchronization based on the transmitted beacons (e.g., that include recently updated clock information). Additionally or alternatively, a station may signal other stations within a NAN when the station detects disappearance of synchronization beacons (e.g., or loss of clock synchronization). In some cases, the signaling may include requests for the one or more other stations to start or stop beacon transmissions as desired.

Abstract: A method includes sending, from a first transmitter to a first receiver, a request to send (RTS) message associated with a first transmit opportunity (TXOP). The RTS message requests the first receiver to indicate whether reuse of the first TXOP is permitted. The method further includes receiving, at the first transmitter from the first receiver, a clear to send (CTS) message responsive to the RTS message.

Abstract: Aspects of the present disclosure provide techniques for synchronizing clocks in a Neighbor Aware Network (NAN) Data Link (NDL) cluster. An exemplary apparatus includes a processing system configured to communicate with one or more members of a group, that includes the apparatus, according to a first data communication window (DCW) timeline having a first offset relative to a first clock associated with a first network cluster, to detect a beacon transmitted by a device of a second network cluster, wherein the beacon comprises timing information of a second clock associated with the second network cluster, to determine whether to initiate a move of the group to the second network cluster, to generate a frame to initiate the move of the group to the second network cluster, the frame comprising a first indication of the timing information of the second clock, and an interface configured to output the frame for transmission.
