UE Data Rate Decoding for Multi-Carrier Transport Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently processing and decoding transport blocks, particularly when multiple repetitions are received across multiple component carriers, due to limitations in summing data rates across these carriers.
Innovation Solution
The proposed solution involves a user equipment (UE) using improved data rate physical downlink shared channel (PDSCH) decoding techniques. The UE monitors and decodes transport blocks based on scheduled repetitions across multiple transmission occasions and component carriers, considering a data rate limit determined by the UE's capability and scheduled by the base station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE processes multiple repetitions of transport blocks across multiple component carriers, then the reliability of data reception is improved, but the power consumption increases
Solution Approach 1:
The patent segments the processing of transport blocks by introducing a capability parameter that divides UEs into different categories (capability 1 and capability 2). This segmentation allows the network to assign appropriate processing modes to different UEs, enabling reliable reception through repetitions while managing power consumption by matching the processing complexity to UE capabilities.
Solution Approach 2:
The patent implements dynamic adaptability by allowing the network to configure the number of repetitions and processing modes based on real-time UE capability reporting. The UE dynamically reports its capability status, and the network dynamically adjusts the scheduling strategy, creating a flexible system that optimizes the balance between reception reliability and power consumption.
2Measurement precision
If the UE counts each transmission occasion separately toward total transport blocks, then the data rate calculation accuracy is improved, but the processing complexity increases
Solution Approach 1:
The patent changes the parameter of how transmission occasions are counted toward data rate calculation. Instead of uniform counting, the system uses capability-based parameters where capability 2 UEs count each transmission occasion separately for improved accuracy, while capability 1 UEs use simplified counting. This parameter change resolves the contradiction by making accuracy improvements available only when the UE capability justifies the additional processing complexity.
3Productivity
If the base station schedules multiple repetitions based on UE data rate capability, then the network efficiency is improved, but the scheduling complexity increases
Solution Approach 1:
The patent applies preliminary action by having the UE report its capability parameters to the base station before actual data transmission begins. This advance information allows the base station to pre-configure appropriate scheduling strategies and repetition patterns, improving network efficiency while managing scheduling complexity through upfront capability assessment rather than real-time complex decision-making.

AI summary
Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may receive, from a network device, a downlink control message that schedules a first and second repetition of a transport block for a downlink shared channel in a first component carrier of multiple component carriers, the first and second repetitions scheduled in a first and second transmission occasion associated with the downlink shared channel. The UE may monitor for the repetitions in the respective transmission occasions, and the UE may decode the transport block based on a number of transmission occasions associated with the downlink shared channel in the component carrier and a data rate limit across the multiple component carriers including the first component carrier.
