Problems solved by technology

However, the proposed method of communicating ICL channel state changes via periodic announcement streams is suboptimal for various reasons
For example, since the receiver is required to switch between listening to the periodic announcement stream and the ICL channel, additional resources (e.g., memory and power) are consumed and latency is increased, which seriously interferes especially with resource-constrained devices (e.g., on performance in terms of available memory, power, etc.)

Abstract

According to various aspects, an isochronous channel can include update slots in which a source device can schedule transmissions to broadcast control information to one or more sink devices. Therefore, the sink device may initially listen to the periodic advertisement stream to receive synchronization information to acquire or reacquire the isochronous channel, and then synchronize to the isochronous channel based on the status information communicated by the source device in update slots.

Description

[0001] Cross references to related applications [0002] This patent application requires the enjoyment of the rights and interests of U.S. Provisional Application No. 62 / 299,524 filed on February 24, 2016, entitled "USING UPDATE SLOT TOSYNCHRONIZE TO BLUETOOTH LE ISOCHRONOUS CHANNEL AND COMMUNICATE STATECHANGES", which has been assigned to this application The assignee of, therefore, the entire content is expressly incorporated into this article by reference. Technical field [0003] In summary, the various aspects and embodiments described herein relate to streaming isochronous data. Specifically, the various aspects and embodiments described herein relate to the use of update time slots to convey status information related to isochronous channels. , Where the source device broadcasts isochronous data to one or more sink devices in the isochronous channel. Background technique [0004] Wireless devices operating in the "Bluetooth" wireless communication spectrum are rapidly emerg...
