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:
A method for wireless communication may include receiving a communication and determining an acknowledgement signature for an acknowledgment in response to the communication. The acknowledgment signature may allow for authentication with the transmitting wireless device. The acknowledgment signature may be based on a key shared with the wireless device. An acknowledgement frame (e.g., acknowledging reception of the communication) may then be sent to the transmitting wireless device. The content of the acknowledgement may be based on the acknowledgement signature. For example, the signature may be included in a frame control, duration, or address field. Determining the acknowledgement signature may include determining a unique signature based on information from the received communication (e.g., a cyclic redundancy check (CRC)), the shared key, and/or a hash function. In some cases, the acknowledgement frame may include an encryption header, and a message integrity check may be included as the acknowledgement signature.
Abstract:
Methods, systems, and devices for wireless communication are described. Wireless devices may use multiple transmission modes to enable association and authentication procedures for wireless devices with different capabilities. For example, a station may receive, in response to a broadcast probe request, a probe response frame formatted according to a first transmission mode. The station may then transmit a second probe request frame formatted according to the first transmission mode. At some later time, the station may identify that the second probe request frame was not received by the wireless device, and may transmit another probe request frame formatted according to an extended range transmission mode. The station may then establish a connection with the wireless device by completing an association and authentication procedure, and proceed to transmit data or control frames formatted according to the extended range transmission mode.
Abstract:
Systems and methods for communication in a wireless network are disclosed. In one aspect, a method includes generating a medium access control (MAC) address for a first group of wireless devices, storing the MAC address for the first group of wireless devices in an address field of a first message, and transmitting, by a first wireless device of the first group of wireless devices, the first message to a second wireless device of the first group of wireless devices. In some aspects, the wireless network comprises a neighbor aware network (NAN). In some aspects, a wireless device may be able to determine a method of encryption or decryption for the first message based at least in part on the MAC address for the first group of wireless devices.
Abstract:
A method of transmitting universal serial bus (USB) frames over a communications channel is disclosed. A USB device receives one or more USB frames from a host device via a network, wherein the one or more USB frames are encapsulated in one or more data packets based on a communications protocol associated with the network. The USB device further synchronizes a local clock signal with a clock signal of the host device using a clock synchronization mechanism of the communications protocol. The USB device then determines a number of USB frames transmitted by the host device and processes the one or more USB frames based, at least in part, on the synchronized local clock signal. For some embodiments, the USB device may receive a frame count value and a corresponding media time value from the host device.
Abstract:
A system and method for managing communications between an access point (AP) and a plurality of wireless stations (STAs) over a wireless medium. The AP schedules each of the plurality of STAs to access the wireless medium during a target wake time (TWT) service period. During a first portion of the TWT service period, the AP communicates with a first subset of the plurality of STAs using a first signaling technique. During a second portion of the TWT service period, the AP communicates with a second subset of the plurality of STAs using a second signaling technique. The second subset of the plurality of STAs does not include any STAs from the first subset.
Abstract:
A method includes generating a first traffic announcement message at a first electronic device of a data link. The first traffic announcement message indicates first data is to be transmitted from the first electronic device to a second electronic device of the data link. The method also includes transmitting the first traffic announcement message to one or more electronic devices of the data link during a first paging window.
Abstract:
A device for transmitting data to a network includes a source subsystem and a communication subsystem. The source subsystem generates a first data packet that includes first timing information that is based on a time that the first data packet is generated. The first timing information is generated responsive to a first timing generator included in the source subsystem. The communication subsystem is coupled to the source subsystem via one or more abstraction layers and is configured to modify the first data packet to generate a modified data packet for transmission to the network. The modified data packet includes the first timing information and second timing information that is based on a time that the modified data packed is transmitted. The communications subsystem includes a second timing generator that is linked to the first timing generator through the one or more abstraction layers to generate the second timing information.
Abstract:
Methods, systems, and devices are described for saving power in wireless communications. One aspect includes providing an indication of a sleep duration for transmission to a wireless node, communicating with the wireless node during a target wakeup time (TWT), wherein the communication comprises at least one of providing data for transmission to the wireless node or obtaining data received from the wireless node, and refraining from providing data for transmission to the wireless node for at least the indicated sleep duration based at least in part on timing of the communication. Another aspect includes receiving an indication of a sleep duration from a wireless node, communicating with the wireless node during a time slot of a TWT, and entering a sleep mode for the indicated sleep duration based at least in part on timing of the communication with the wireless node during the time slot of the TWT.
Abstract:
Methods, systems, and devices are described for wireless communication. A device with multiple radios may establish a wireless local area network (WLAN) connection with a multi-radio gateway (i.e., a multiPHY gateway) and a wide area network (WAN) connection with a base station. The multi-radio device may receive a proxy capability indication from the multi-radio gateway and may transmit connection information relating to the second wireless connection. The multi-radio device may then establish a tunnel to the base station utilizing a proxy entity within the multi-radio gateway and close a physical (PHY) connection of the second wireless connection in order to save power. The multi-radio gateway may receive messages (e.g., paging, broadcast, or multicast messages) from the base station on behalf of the multi-radio device using the proxy entity, and tunnel the messages through to the multi-radio device using the WLAN wireless connection.
