    Abstract: The present disclosure provides for role switch with perceptible continuity of audio streaming during the role switch. The role switch occurs in two stages, with a first stage including a host link role switch and a second stage including a relay link role switch. For example, the host link role switch concerns the relationship of each audio receiver device to the host device, where the master device receives audio directly from the host for relay to the slave. The relay link role switch concerns a relationship between the audio receiver devices. For example, the communication master controls timing, such as when to send packets between the master and slave devices. Each stage of the two stage procedure may take approximately 100 ms or less. Between each stage, the audio buffers of the master and slave devices have an opportunity to refill.

  • Patent number: 10181938
    Abstract: Methods and apparatus of a base station or a User Equipment (UE) in communication with each other are provided. The base station transmits on a first cell using frequency domain duplexing or time division duplexing associated with a first uplink-downlink (UL-DL) configuration and on a second cell using time division duplexing associated with a second UL-DL configuration. An UL-DL configuration corresponds to a number of transmission time intervals (TTIs) that include downlink (DL) TTIs where a communication direction is from the base station, uplink (UL) TTIs where a communication direction is to the base station, and special TTIs where a communication direction is both from the base station and to the base station. The first UL-DL configuration includes an UL TTI. The second UL-DL configuration does not include any UL TTI. The base station receives, from the UE, a physical UL control channel (PUCCH) on the first cell.

  • Patent number: 10142951
    Abstract: An LAA-LTE wireless device obtains data to be transmitted in subframes over a shared spectrum. The wireless device transmits a reservation message over the shared spectrum. The reservation message indicates that an initial synchronization message will be retransmitted a specified number of times at specified intervals, such as with a predetermined number of subframes between each retransmitted synchronization message. The wireless device transmits the initial synchronization message over the shared spectrum.

  • Patent number: 10136333
    Abstract: Methods, systems, and devices are described for wireless communication. A device may use enhanced reporting mechanisms to support control information reporting on shared spectrum. In some cases, a device may utilize enhanced component carriers (eCCs) for data transmissions. In one example, the device may transmit control information (e.g., ACK/NACK, CSI, etc.) to a corresponding device using a CCA exempt transmission (CET). In another example, a device may report control information quasi-periodically. For instance, a device may be assigned a specified interval and a control feedback window for reporting control information (e.g., CSI). The window may provide a duration prior and subsequent to the specified interval during which a UE may transmit control information. For example, the device may perform a CCA reserving the channel for a duration that does not include the specified interval but may transmit feedback information based on determining the specified interval falls within the assigned window.

  • Patent number: 10080195
    Abstract: A system and method for managing power in a subnet having a hub in communication with one or more nodes is disclosed. The hub and nodes communicate using one or more non-contention access methods, such as scheduled, polled or posted access. The node may enter a sleep or hibernation state while no scheduled, polled or posted allocation interval is pending. The hibernation state allows the node to hibernate through one or more entire beacon periods. In the sleep state, the node may be asleep between any scheduled, polled and posted allocation intervals for the node or during another node's scheduled allocation interval in a current beacon period. By selecting which access scheme is in use, the node and hub can increase the node's chances to be in hibernation or sleep state and minimize power consumption.
