Solution Approach 1:

The patent segments the collision management task by introducing device-specific control indication parameters that are uniquely configured for each wireless device. These parameters include device identifiers, priority levels, and timing information that enable individual collision resolution without requiring centralized coordination. Each device manages its own collisions independently using these segmented parameters.

Inventive Principle:

Solution Approach 1:

The patent applies preliminary action by pre-configuring device-specific control indication parameters including priority levels and timing information before collisions occur. The receiving device has advance knowledge of incoming transmission parameters and can pre-adjust beam configurations accordingly, reducing real-time processing delays when collisions actually happen.
