Uplink Licensed Resource Multiplexing for NR Transmission Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing uplink data transmission methods in New Radio (NR) systems do not ensure efficient transmission of data on uplink licensed resources due to inadequate multiplexing of Logical Channels (LCHs), leading to suboptimal resource allocation and utilization.
Innovation Solution
A method and device configuration that involves receiving signaling from the network to allocate an uplink licensed resource and multiplexing data of a first LCH based on specific service type features, such as reliability and delay, to ensure efficient data transmission by matching the service type features with the allocated resource.

Engineering Contradiction Analysis
1Productivity
If data of multiple Logical Channels is multiplexed to uplink licensed resource according to standard LCP process, then resource allocation follows configured rules, but transmission efficiency on uplink licensed resource cannot be ensured
Solution Approach 1:
The patent changes the multiplexing parameters by introducing service type feature matching (reliability and delay requirements) as new criteria for allocating uplink licensed resources to LCHs. This goes beyond the standard LCP process which only uses priority, PBR, and BSD parameters. By adding service type matching, the system ensures that high-reliability or low-delay services receive appropriate resource allocation, thereby improving transmission efficiency while maintaining manageable complexity through rule-based matching.
2Productivity
If standard LCP process is used for multiplexing, then configuration rules are followed, but resource utilization is suboptimal
Solution Approach 1:
The patent applies preliminary action by pre-configuring service type features (reliability and delay requirements) for each LCH and pre-establishing matching rules between service types and uplink licensed resource characteristics. When uplink resources are allocated, the terminal device can directly match pre-configured service types with resource features without complex real-time decisions. This improves resource utilization by ensuring appropriate service-resource matching while keeping operations simple through pre-established rules.
