Abstract: Embodiments relate to wireless stations that operate to configure direct communication between the wireless stations without utilizing an intermediate access point. In embodiments, a wireless station may transmit, to a first peer wireless station, a first availability schedule that may include one or more types of committed availability and receive, from the first peer wireless station, a second availability schedule applicable to the wireless station but not other peer wireless stations. The types of committed availability may include a first type that is non-cancelable and a second type that is cancelable. The second availability schedule may be the second type. The wireless station may be further configured to transmit, to a second peer wireless station of the plurality of peer wireless stations, a third availability schedule where the third availability schedule may be the first type.

Abstract: Embodiments described herein relate to providing reduced power consumption in wireless communication systems, such as 802.11 WLAN systems. Timing information regarding power save opportunities (PSOPs) may be provided in communication frames, which may inform mobile devices of expected frame exchange periods during which they may transition to a Doze state. Additional PSOP information may be included in beacon frames, which may inform mobile devices of expected multicast periods during which they may transition to a Doze state. This may operate to provide improvements in terms of power consumption.

Abstract: In some embodiments, one or more wireless stations operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. Embodiments of the disclosure relate to a mechanism for a wireless station to discover a neighboring peer wireless station, e.g., via peer-to-peer Wi-Fi communications, receive a synchronization beacon(s) from the neighboring peer wireless station, and synchronize timing with the neighboring peer wireless station based at least in part on the synchronization beacon(s). In addition, the wireless station may transmit, e.g., via Wi-Fi peer-to-peer communications, a data beacon to one or more neighboring wireless devices stations, wherein the one or more neighboring wireless stations are configured to synchronize timing with the wireless station based on the data beacon.

Abstract: In embodiments, one or more wireless stations operate to configure direct communication with neighboring mobile stations, i.e., direct communication between the wireless stations without utilizing an intermediate access point. Embodiments of the disclosure relate a mechanism for coexistence of various radio access technologies during peer-to-peer communications. In some embodiments, a first communication may be scheduled in one or more time slots with a peer station according to a first radio access technology (RAT), an end time of the first communication during a first time slot of the one or more time slots may be determined, and a second communication according to a second RAT may be transmitted. At least a portion of the second communication may be performed during the first time slot. In some embodiments, the first and second communications may be transmitted on the same channel.

Abstract: In embodiments, one or more wireless stations operate to configure direct communication with neighboring mobile stations, i.e., direct communication between the mobile stations without utilizing an intermediate access point. Embodiments of the disclosure relate to NAN datapath scheduling and NAN pre-datapath operation setup and scheduling. The NAN datapath embodiments described herein provide a mechanism through which devices can communicate and provide services. In particular, embodiments described herein provide a mechanism for NAN datapaths to support various levels of quality of service (QoS). Aspects of the datapath development include datapath scheduling, including datapath setup and scheduling attributes, as well as pre-datapath operation triggering and scheduling. Scheduling may include determination of a type of datapath, including paging and synchronized datapaths. NAN data cluster base schedules may be scheduled as equal-sets or subsets of datapath schedules. The datapath model may be implemented for unicast and multicast communication between wireless stations.

Abstract: A wireless local area network (WLAN) device processes received samples for a radio frequency channel in an unlicensed radio frequency band to detect radio frequency interference from a long term evolution (LTE) wireless communication system. The WLAN device performs a correlation of received time-domain samples to detect the presence of a cyclic prefix for an orthogonal frequency division multiplexing (OFDM) symbol used by the LTE wireless communication system. The WLAN device searches for cross-correlation peaks (1) that exceed a peak power threshold value, (2) that a ratio of which exceed a ratio threshold, and (3) that are separated by a time period corresponding to the OFDM symbol. The WLAN device detects the presence of the LTE wireless communication system without decoding the OFDM symbols.
