Cross-BSS TWT Coordination to Reduce Wireless Wake-Time Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices experience increased delay times and degraded service quality due to overlapping target wake times (TWT) with external devices in different basic service sets (BSS), leading to inefficiencies in data transmission and reception.
Innovation Solution
An electronic device exchanges TWT parameters with external devices in different BSSs to align and adjust TWT durations, reducing overlapping sections and minimizing delay times.

1Use of energy by moving object
If TWT parameters are set without considering external devices in different BSS, then battery performance is improved through reduced power consumption, but data transmission delay increases due to overlapping TWT periods
Solution Approach 1:
The electronic device obtains TWT parameters of external devices in different BSS through feedback mechanisms (request signals and response signals), uses this information to determine and adjust its own TWT parameters, thereby avoiding overlapping periods and reducing data transmission delays while maintaining power savings
Solution Approach 2:
The electronic device performs preliminary actions by obtaining TWT parameters of external devices before setting its own TWT parameters, allowing it to proactively avoid overlapping periods and plan data transmission timing in advance, thus reducing delays
2Productivity
If TWT parameters are adjusted to avoid overlapping with external devices in different BSS, then data transmission efficiency is improved, but device complexity increases due to additional parameter exchange and coordination
Solution Approach 1:
The request signal and response signal serve multiple functions: they not only exchange TWT parameters but also establish coordination between devices in different BSS, enabling the system to achieve both power savings and reduced delays through a unified communication mechanism

AI summary
An electronic device comprises: a communication circuit configured to transmit and/or receive data to and/or from a first external electronic device connected through short-range wireless communication; and a processor. The processor may be configured to: receive, from the first external electronic device, target wake time (TWT) parameters of the first external electronic device; transmit a request signal for information related to TWT parameters of a second external electronic device belonging to a basic service set (BSS) different from a BSS including the electronic device and the first external electronic device; determine whether to configure TWT parameters of the first external electronic device based on whether a response signal corresponding to the request signal is received; and configure the TWT parameters of the first external electronic device based on TWT parameters.
