UE Channel Counting Method for 5G Capability Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 3GPP specifications do not provide clear methods for counting cancelled or dropped uplink and downlink channels per slot for user equipment (UE) capabilities, leading to increased complexity and resource utilization in processing channels.
Innovation Solution
A method to count all scheduled or configured uplink and downlink channels, except under specific conditions where there is sufficient time for the UE to prioritize or cancel transmissions, ensuring dropped channels are counted as processed channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE counts all scheduled or configured channels including cancelled or dropped channels, then the UE capability determination becomes more accurate, but the processing complexity increases
Solution Approach 1:
The patent segments the channel counting process into distinct categories: scheduled channels, configured channels, and cancelled/dropped channels. By defining specific conditions for each category and establishing clear rules for when to include or exclude them from the count, the patent reduces ambiguity and simplifies the overall determination process while maintaining accuracy.
Solution Approach 2:
The patent establishes preliminary rules and criteria for identifying cancelled or dropped channels before the actual capability determination process. By pre-defining conditions such as sufficient time for prioritization or cancellation, the UE can efficiently filter channels without complex real-time analysis, reducing processing complexity while ensuring accurate counting.
2Productivity
If the UE processes more channels per slot to increase capability, then the resource allocation efficiency improves, but the risk of processing errors increases
Solution Approach 1:
The patent introduces dynamic adjustment mechanisms that allow the UE to adapt its channel processing capacity based on actual conditions. By considering factors such as available time for prioritization or cancellation, the UE can dynamically determine how many channels to process in each slot, optimizing both productivity and reliability according to real-time system state.
Solution Approach 2:
The patent changes key parameters such as the time threshold for prioritization or cancellation based on UE capability and system conditions. By adjusting these parameters, the system can balance between processing more channels (higher productivity) and maintaining processing reliability, allowing flexible optimization without fixed constraints.
3Reliability
If the UE drops lower priority channels to handle higher priority transmissions, then the service quality for critical applications improves, but the overall channel utilization decreases
Solution Approach 1:
The patent enables the UE to autonomously perform prioritization and cancellation of channels based on predefined rules and service requirements. The UE itself determines which channels to drop or process by evaluating priority levels and available resources, eliminating the need for complex external coordination while maintaining service reliability and optimizing channel utilization.
Solution Approach 2:
The patent incorporates feedback mechanisms where the UE reports its capability determination results and channel processing status back to the network. This feedback loop allows the network to adjust scheduling decisions and channel allocations, ensuring that high-priority services receive adequate resources while maximizing overall channel utilization through coordinated resource management.

AI summary
An apparatus and method are provided for counting a number of uplink and/or downlink channels per slot for a UE capability in order to determine a maximum number of channels a UE (701) is capable of processing per slot. A UE (701) counts all PDSCHs or PUSCHs that the UE (701) is scheduled or configured to receive or transmit, respectively, except for exception 1: when the UE (701) receives a PDCCH, which ends in a symbol i, scheduling a DG-PUSCH that overlaps in time with a CG PUSCH starting in a symbol j on a same serving cell, wherein a beginning of the symbol j is at least N 2 symbols after an end of the symbol i, the CG PUSCH is not counted, exception 2: when the UE (701) receives a PDCCH, which ends in a symbol i, scheduling a PUSCH on a serving cell for an HPN, and the UE (701) is allowed to transmit a CG PUSCH with the same HPN starting in a symbol j, wherein a beginning of the symbol j is at least N 2 symbols after an end of the symbol i, the CG PUSCH is not counted, or exception 3: when the UE (701) receives a PDCCH, which ends in a symbol i, scheduling a PDSCH with a C-RNTI or an MCS-C-RNTI overlapping in time with an SPS PDSCH starting in a symbol j in a same serving cell, wherein a beginning of the symbol j is at least N 2 symbols after an end of the symbol i, the SPS PDSCH is not counted, and generates UE capability information based on the counted number of the PDSCH or PUSCH per slot.
