BWP Priority Configuration for High-Priority Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current protocols in new radio (NR) systems cannot distinguish the priorities of different bandwidth parts (BWPs), leading to inadequate transmission performance for high-priority data, as the activation of BWPs through downlink control information does not support dynamic priority indication for different service types.
Innovation Solution
A method is introduced to determine and configure priorities for BWPs, allowing terminal devices to perform signal transmissions or report uplink control information based on these priorities, ensuring that high-priority data is transmitted preferentially by allocating transmit power and resource usage accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the current protocol is used for BWP activation through DCI, then the system can support multiple BWPs with different service types, but the protocol cannot distinguish the priorities of different BWPs, leading to inability to guarantee transmission performance for high-priority data
Solution Approach 1:
The patent introduces a priority parameter (priority indicator) associated with each BWP configuration. The terminal device determines the priority of each BWP based on this indicator, and when multiple BWPs need simultaneous transmission, the terminal preferentially transmits on BWPs with higher priority. This resolves the contradiction by adding a simple priority parameter to the existing BWP configuration without fundamentally changing the protocol structure.
2Adaptability or versatility
If dynamic scheduling is used for data transmission on BWPs, then the network can flexibly allocate resources, but the priority indication for different service types is not supported by current technology
Solution Approach 1:
The patent applies preliminary action by configuring the priority indicator for each BWP in advance through RRC signaling or other higher-layer signaling before dynamic scheduling occurs. When the network dynamically schedules data transmission on multiple BWPs, the terminal already has the priority information needed to make transmission decisions. This resolves the contradiction by providing priority information beforehand rather than requiring additional dynamic signaling.
3Productivity
If multiple BWPs are activated simultaneously for different service types, then the system can support diverse services, but the terminal cannot preferentially guarantee transmission performance for high-priority data without priority distinction
Solution Approach 1:
The patent applies local quality by allowing different BWPs to have different priority indicators, creating local distinctions in transmission priority across different frequency resources. When the terminal needs to transmit on multiple BWPs simultaneously, it identifies which BWPs have higher priority indicators and allocates transmission resources preferentially to those BWPs. This resolves the contradiction by enabling quality differentiation at the local BWP level while maintaining overall system productivity.
