◆Improvements to Bluetooth Channel Sounding Inline PCT Transfer
In ' Bluetooth Channel Sounding ,' a technology that measures the distance between devices from the phase difference and round-trip time of signals, accuracy and efficiency have been improved by reducing overhead by eliminating extraneous data when measuring the phase difference.

◆Introduction of PHY (Physical Layer) specific round-trip time in Bluetooth Channel Sounding
In Bluetooth Channel Sounding, the round-trip time previously used a value applied to all PHYs, but now it will be possible to use a value for each PHY individually, improving accuracy and performance in scenarios using multiple layers.

◆Improved Bluetooth bit depth
The number of bits transmitted between Bluetooth transmitting and receiving devices has almost reached its limit, and the initial 512-bit limit for commands and the 64-bit limit for Bluetooth LE communication were becoming bottlenecks in future specification updates. In the future, these limitations will be resolved by expanding the bitmask for supported commands from 64 octets to 251 octets, and the LE mask from 8 octets to 255 octets.

◆ Relaxation of Bluetooth ACP and C/I restrictions
Relaxing the Bluetooth control profile ( ACP ) C/I restrictions enables a more power-efficient wireless architecture.
