APPARATUS AND METHOD FOR REDUCING DELAY OF BUFFERING IN SHORT RANGE WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18208169 titled 'APPARATUS AND METHOD FOR REDUCING DELAY OF BUFFERING IN SHORT RANGE WIRELESS COMMUNICATION SYSTEM

Simplified Explanation

The patent application describes a method for operating a first apparatus in a short-range wireless communication system. The first apparatus includes a host stack, a first controller stack, a memory, and a transceiver. The host stack and the first controller stack are connected through a host controller interface (HCI).

  • The method involves transporting HCI command information from the first processor to the second processor, enabling data transport from the first controller stack of the first apparatus to a second controller stack of a second apparatus.
  • Multiple service data units (SDUs) generated by the first processor are transported to the second processor, with each SDU being transported at a configured sub interval.
  • Based on the HCI command information, the transceiver transports multiple protocol data units (PDUs) to the second apparatus without buffering after each SDU is received by the second processor. This transport of PDUs occurs within one isochronous event.

Potential applications of this technology:

  • Short-range wireless communication systems, such as Bluetooth or Wi-Fi, can benefit from this method of data transport between different apparatuses.
  • It can be applied in various devices that require efficient and low-latency communication, such as smartphones, tablets, laptops, IoT devices, and wearable devices.

Problems solved by this technology:

  • The method eliminates buffering in the first controller stack, reducing latency and improving the efficiency of data transport.
  • It ensures that each SDU is transported separately at configured sub intervals, allowing for better control and synchronization of data transmission.
  • By transporting PDUs without buffering after each SDU is received, the method minimizes delays and improves the real-time performance of the communication system.

Benefits of this technology:

  • Reduced latency in data transport improves the responsiveness and overall performance of short-range wireless communication systems.
  • Efficient transport of SDUs and PDUs ensures better synchronization and control of data transmission.
  • The method enables real-time communication within one isochronous event, making it suitable for applications that require low-latency and time-sensitive data transfer.


Original Abstract Submitted

According to various embodiments of the present disclosure, a method of operating a first apparatus in a short-range wireless communication system, the first apparatus includes: a first processor corresponding to a host stack; a second processor corresponding to a first controller stack; a memory; and a transceiver, wherein the host stack and the first controller stack are connected through a host controller interface (HCI), the method includes: in relation to data transport from the first controller stack of the first apparatus to a second controller stack of a second apparatus, transporting, from the first processor to the second processor, HCI command information configured so that there is no buffering in the first controller stack; transporting a plurality of service data units (SDUs) generated by the first processor to the second processor—each of the plurality of SDUs is transported to the second processor apart at each configured sub interval-; and based on the HCI command information, transporting, by the transceiver, each of a plurality of protocol data units (PDUs) based on each of the plurality of SDUs to the second apparatus without buffering after each of the plurality of SDUs is received by the second processor, wherein transport of the plurality of PDUs is performed within one isochronous event.
