A method for configuring and updating link parameters based on characteristics for data transmission in a short-range wireless communication system, allowing for separate configurations for data transmission from a slave device to a master device and vice versa, enabling the transmission of audio and control data through a shared link.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single link is used for data transmission between master and slave devices, then device complexity is reduced, but transmission efficiency and reliability deteriorate due to inability to optimize parameters for different data types
Solution Approach 1:
The patent divides a single communication link into multiple logical links (first link for master-to-slave data transmission, second link for slave-to-master data transmission). This segmentation allows independent parameter configuration for each direction, optimizing transmission efficiency for different data types while maintaining manageable device complexity through structured organization.
2Productivity
If link parameters are configured separately for different data transmission directions, then data transmission efficiency is improved, but device complexity increases due to multiple parameter sets
Solution Approach 1:
The patent applies local quality by configuring parameters specifically tailored to each link's characteristics. The first link parameters are optimized for master-to-slave data transmission, while the second link parameters are optimized for slave-to-master data transmission. This localized optimization improves overall transmission efficiency without requiring complex global reconfiguration, as each link can be independently tuned to its specific needs.
3Use of energy by moving object
If Bluetooth transmission is used for short-range communication, then energy consumption is reduced, but transmission distance is limited to maximum of 100m
Solution Approach 1:
The patent implements dynamic parameter adjustment for link configuration, allowing the system to adapt transmission parameters based on communication needs. This dynamic approach enables Bluetooth to operate at optimal power levels for short-range communication while maintaining the ability to adjust parameters for extended range when necessary, balancing energy consumption with transmission distance requirements through flexible, context-aware parameter selection.

AI summary
Provided are a method for transmitting and receiving data and a device for same in a short-range wireless communication system. More specifically, the method comprises the steps of: receiving, from a first slave device, a first advertising message for providing a service related to transmitting and receiving the data; forming a shared link, which is for transmitting and receiving the data and is formed on the basis of the first advertising message, on the basis of link parameters for the configuration of the shared link, the shared link including (i) a first link for data transmission from a master device to a slave device, and (ii) a second link for data transmission from the slave device to the master device; and receiving, from a second slave device, a second advertising message for providing the service. wherein the link parameters applied to the shared link are updated on the basis of the second advertising message in order to add the second slave device as a slave device related to the shared link, and the updated link parameters are configured as different values for each of (i) the first link, and (ii) the second link on the basis of the characteristics of the first and second links.
