Abstract: Disclosed are techniques to use existing BLE broadcast-based signaling protocols to achieve sub-1 ms peripheral-to-central latency even when multiple peripheral devices share the air-time. The techniques adapt existing BLE advertising or broadcast signaling protocols to efficiently allocate air-time to support frequent peripheral-to-central transmissions that are relatively short in duration and less frequent central-to-peripheral transmissions. A broadcast isochronous group (BIG) protocol may be used to reduce peripheral-to-central latency by aggregating broadcast isochronous streams (BIS) from peripheral devices into a BIG. A one-to-many broadcast event that may carry other broadcast data from the central device to the peripheral devices may be used for time synchronization by the peripheral devices and to configure time parameters of broadcast from the peripheral devices. A reverse many-to-one broadcast from the peripheral devices to the central device may be based on the time parameters.

Abstract: Wireless communication schemes and techniques are described, wherein a secondary device is configured to eavesdrop information communicated between a source and a primary device. Secondary device transmits a NACK signal to jam ACK signals from the primary device to the audio source, forcing a retransmit of audio information from the source to the primary, and available over an eavesdropping link between the secondary device and the source.

Abstract: A UE may determine a frame structure for narrowband communications, the frame structure corresponding to one frame structure from a group of TDD frame structures of different downlink and uplink subframe configurations. The UE receives configuration information indicating a first carrier to monitor for a BCH and/or a SIB1. Then, the UE receives a PSS, an SSS, and the BCH and/or the SIB1 using the frame structure determined for the narrowband communications. The first carrier that is used to receive the BCH and/or the SIB1 may be different from a second carrier used to receive one or more of the PSS or the SSS.
