Wireless Node Timing Reference Management for Concurrent Communications

The patent segments the timing reference management by introducing timing advance groups (TAGs) that divide communications into different groups, each with its own timing reference. This allows concurrent communications to use different timing references (first TAG and second TAG) while maintaining overall system organization, thus preventing time misalignment without excessive complexity.

The patent implements dynamic timing reference selection where the wireless device can switch between first and second timing references based on communication requirements. The timing reference is dynamically adjusted using timing advance values that are updated through timing advance commands, allowing the system to adapt to changing communication conditions while maintaining time alignment.

The patent creates a universal timing reference management framework where a single timing reference (first timing reference) serves as the default for all communications, while a secondary timing reference (second timing reference) is only activated when needed for specific concurrent communications. This multi-functional approach allows the system to handle both single-reference and multi-reference scenarios through a unified mechanism.

The patent applies local quality by assigning different timing reference characteristics to different communication contexts. The first timing reference is used for communications requiring stable, predictable timing, while the second timing reference is applied locally to specific concurrent communications that require different timing characteristics, optimizing each communication's timing properties.
