摘要： An apparatus and methods are provided for opportunistically conducting data communications on multiple wireless channels. In these methods, a device is engaged in data communications with a second device and receives a conflicting communication demand requiring action on one or more channels other than the data-communication channel (e.g., to conduct a channel scan, to issue or receive a beacon). The device arranges a schedule of channel switches to satisfy the communication demand and advises the second device of the schedule, and may explicitly invite the second device to implement the schedule. To the extent the second device does so, the data communications continue on the other channels. The devices may be participating in a synchronized peer-to-peer communication environment that requires their attendance on the data-communication channel and that is not associated with the other channels.

摘要： An electronic device that communicates with a second electronic device is described. During operation, an electronic device communicates first messages with the second electronic device in time slots corresponding to first channels in a first band of frequencies using a peer-to-peer communication protocol (such as neighbor awareness networking or NaN), where, in a given time slot, a given first channel in the first band of frequencies is used in the communication of the first messages. Moreover, the electronic device communicates second messages with the second electronic device in the time slots corresponding to second channels in a second band of frequencies using the peer-to-peer communication protocol, where, in the given time slot, a given second channel in the second band of frequencies is used in the communication of the second messages. Note that the communicating of the first messages and the second messages may at least partially overlap in time.

摘要： Some embodiments include an apparatus and method for enabling concurrent peer-to-peer (P2P) communications via a scheduled resource unit (RU) allocated by an access point (AP). For example, the AP may use a trigger frame to schedule uplink (UL) multi-user (MU) access for a first station of a plurality of stations by allocating an RU to the first station. Instead of using the allocated RU for UL infrastructure communications with the AP, the first station may utilize the allocated RU for a P2P communications with a second station. In some embodiments the AP facilitates RU utilization for P2P communications between stations. In some embodiments, the first station uses the allocated RU and the AP may be unaware of the P2P communications.

摘要： This disclosure relates to methods for conducting multilink communications between a user equipment (UE) device and a remote device over a wireless local area network (WLAN). The UE device periodically transmits communications to the remote device over a first frequency band on the WLAN using a first radio. The UE device may determine to switch from transmitting communications to the remote device over the first frequency band to transmitting said communications over a second frequency band. The UE device then transmits communications to the remote device over the second frequency band on the WLAN.

摘要： One or more wireless stations may operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. A mechanism for wireless stations to learn preferred channels of neighboring wireless stations and to schedule channel sequences within a time period based on the learned channels may include advertisement of preferred channels and adaptation of channel sequences, based on the preferred channels, to maximize bandwidth utilization.

摘要： This disclosure relates to transmitting multicast information over a network, such as a wireless local area network (WLAN). A source device may transmit a multicast and a request for feedback to a plurality of sink devices. The sink devices may transmit feedback based on whether they successfully decoded the multicast. The source device may retransmit the multicast (or a portion thereof) based on the feedback.

摘要： In one set of embodiments, one or more client stations operate to configure Neighbor Awareness Networking (NAN)—direct communication with neighboring client stations, i.e., direct communication between the client 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. 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 client stations.
