Abstract: Embodiments relate to an integrated circuit of an electronic device that coordinates activities with another integrated circuit of the electronic device. The integrated circuit includes an interface circuit and a processor circuit. The interface circuit communicates over a multi-drop bus connected to multiple electronic components. The processor circuit receives an authorization request from the integrated circuit via the interface circuit and the multi-drop bus. The received authorization request relates to authorization to perform an activity on the other integrated circuit. In response to receiving the authorization request, the processor circuit determines whether the other integrated circuit is authorized to execute the activity. In response to determining that the other integrated circuit is authorized to execute the activity, the processor circuit sends, to the other integrated circuit over a configurable direct connection, an authorization signal authorizing the other integrated circuit to execute the activity.

Abstract: Communication between a source device and one or more pairs of accessory devices and between accessory devices within pairs of accessory devices is scheduled using slot availability masks (SAMs). A primary accessory device provides to the source device information about requirements for communication between the primary accessory device and a secondary accessory device. The source device determines a SAM map that specifies a periodic cycle of time slots, with time slots marked as available or unavailable for transmission and/or reception. The SAM map satisfies requirements to avoid collisions between communication between the source device and the accessory devices and communication between accessory devices within pairs of accessory devices. When multiple pairs of accessory devices establish connections with the source device, internal communication between accessory devices within pairs of accessory devices are aligned to use at least a common overlapping set of time slots.

Abstract: Exemplary embodiments include a system having a first device and a second device that are configured to establish a connection via a short-range protocol. The first and second devices perform an advertisement process to automatically identify that the first and second devices are capable of establishing the connection, the advertisement process comprising one of the first device or second device broadcasting an advertisement and the other one of the first device or the second device scanning for the advertisement, wherein, upon the first and second devices identifying that they are capable of establishing the connection, the first and second devices perform a paging mechanism to establish the connection, the paging mechanism comprising one of the first device or the second device transmitting a page and the other one of the first device or the second device scanning for the page, wherein the page triggers an operation to establish the connection.

Abstract: A user equipment (UE) tunes a transceiver of the UE to a first frequency associated with a first channel, transmits a first short packet to a second UE on the first channel and determines whether a first indication was received from the second UE in response to the first short packet. The first indication indicates that the first channel satisfies one or more predetermined criteria. The UE transmits then the primary data to the second UE on the first channel in response to the first indication being received from the second UE.

Abstract: Disclosed herein are system, method, and computer program product embodiments for synchronizing the switching of different wireless platforms to different portions of a frequency band. An embodiment, at a first wireless platform, operates by receiving a band switch request message from a second wireless platform, wherein the band switch request message comprises a band switch delay period for the second wireless platform. The embodiment calculates a band switch time based on a band switch delay period for the first wireless platform and the band switch delay period for the second wireless platform. The embodiment transmits a band switch accept message comprising the band switch time to the second wireless platform. The embodiment sets a first filter to operate on a second portion of the frequency band based on the band switch time. The embodiment then operates on the second portion of the frequency band.

Abstract: A source device connected to a sink device over a first wireless connection. The source device identifies a frame for retransmitting a voice packet associated with a real time application from the source device to the sink device, determines that a precedent operation is scheduled for the frame, delays the precedent operation to a subsequent frame, following the retransmitting of the voice packet and scheduling a retransmission operation for retransmitting the voice packet during the frame.
