HARQ Entity Prioritization for UL Grant Collisions

The patent changes the parameter of grant prioritization by introducing a priority indicator that dynamically determines which UL grant (dynamic or configured) takes precedence during collisions. This parameter change allows the system to flexibly adjust transmission behavior based on current network conditions and QoS requirements, resolving the contradiction between reliability and latency by enabling optimal grant selection without fixed rigid rules

The patent introduces dynamic prioritization where the priority relationship between dynamic and configured UL grants is not fixed but can change based on real-time conditions. The HARQ entity dynamically determines which grant to prioritize when collisions occur, allowing the system to adapt to varying traffic patterns and network states, thus improving both reliability and latency performance under different scenarios

The patent implements self-service by enabling the HARQ entity to autonomously handle grant collisions using predefined prioritization rules. The system automatically determines which UL grant to prioritize based on the priority indicator and collision detection, without requiring complex external coordination or manual intervention. This self-service mechanism manages collision handling complexity while maintaining high data transmission capacity

The patent segments the UL grant handling process into distinct functional components: grant reception, collision detection, priority determination, and transmission execution. By dividing the complex collision handling task into manageable segments with clear responsibilities, the system can process multiple UL grants efficiently while keeping the complexity of each individual processing stage可控
