Abstract: An acknowledgment (ACK) frame has two parts: a group ACK part and a scheduling information part. In the group ACK part, an ACK/NACK indicator is included for a previous uplink (UL) transmission per station (STA). In the scheduling information part, information included for the following UL transmission per selected STA may comprise, for example, one or more of: a number of selected STAs, a media access control (MAC) address of each selected STA, a data transmission duration per selected STA, a transmission rate per selected STA, a request transmission duration, a pilot transmission order, or a STA transmission order.

Abstract: In a particular embodiment, a method includes determining, at a first mobile device, a post-discovery communication technique for communicating within a mobile device cluster after a discovery interval. During the discovery interval, a discovery message may be sent. The discovery message indicates the post-discovery communication protocol for communicating within the mobile device cluster after the discovery interval. The discovery message may further indicate a time interval for sending and receiving a paging request. In response to the receipt of the discovery message a second mobile devices may send a paging request, the paging request including a security information request. The method further includes sending from the first mobile device a paging response including security information and exchanging one or more post-discovery communications with the second mobile device using the security information.

Abstract: Systems, methods, and devices for communicating packets having a plurality of types are described herein. In some aspects, the packets include a MAC header with a frame control field. The sub-fields included in a particular frame control field may be based on the type of information to be communicated to the receiving device.

Abstract: Devices and methods for synchronized group messaging in a wireless communication system are described. Multicast transmissions, such as those in a dense network, can cause significant medium usage because same multicast packet is likely sent by multiple APs at different time. Medium usage in such implementations may be redundant. As such, the transmission medium is not used optimally. Devices and methods which coordinate and align group messages (e.g., multicast packets) amongst APs are described. Each AP may be configured to transmit identical packets at the same time. Therefore, medium usage can be reduced, while the range can be extended due to accumulated energy from APs.

Abstract: An apparatus includes a memory and a processor coupled to the memory. The processor is configured to determine a first identifier that corresponds to a data link group identifier of a data link group and to determine a second identifier that corresponds to a device. The processor is further configured to generate an internet protocol (IP) address for a data link interface of the device based on a combination of a data link routing prefix, the first identifier, and the second identifier.

Abstract: A first neighbor awareness networking (NAN) device may access data network infrastructure and may advertise a service associated with the data network infrastructure to a second NAN device. For example, the first NAN device may announce the service via a service announcement. The second NAN device may subscribe to the service through the first NAN device, and the second NAN device may proxy the service announcement to another NAN device. The other NAN device may also subscribe to the service in response to receiving the service announcement. For example, the second NAN device may operate as a “relay point” to provide the service to the other NAN device.

Abstract: Methods and systems for acknowledging multi-user transmissions on a wireless network include receiving a multi-user transmission comprising a first message from the first device and a second message from the second device, generating a first media access control protocol data unit, the first media access control protocol data unit acknowledging the first message and including a destination address field identifying the first device, generating a second media access control protocol data unit, the second media access control protocol data unit acknowledging the second message and including a destination address field identifying the second device, generating an aggregated media access control protocol data unit (A-MPDU) comprising the first media access control protocol data unit (MPDU) and the second media access control protocol data unit (MPDU); and transmitting the aggregated media access control protocol data unit (A-MPDU) on the wireless network.

Abstract: In some examples, a method includes generating, at a first device, a paging message including an indication of whether the first device is available for a particular time period during which devices of a data link group of a neighbor aware network (NAN) are configured to operate in an active operating mode. The method also includes sending the message from the first device to one or more devices of the data link group of the NAN.

Abstract: Techniques are described that provide nested constellations in which a lower order modulation scheme may be nested within constellation points of a higher-order modulation scheme. A higher-order modulation scheme, having a first constellation, may be used for a first subset of transmissions (e.g., data payload transmissions). A lower-order modulation scheme, having a second constellation, may be used for a second subset of transmissions (e.g., reference signal transmissions, embedded control transmissions, tapered payload transmissions, etc.). A subset of constellation points of the first constellation may be selected for transmitting the second subset of transmissions. A receiver may receive the transmissions and demodulate/decode the transmissions. In the event that other transmitters are transmitting concurrently, and using similar nested constellation techniques, the receiver may be able to perform improved interference mitigation compared to interference mitigation that may be performed on interfering signals that use different constellation points.
