Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
eRedCap terminals face challenges in processing multiple PDSCH channels due to reduced baseband bandwidth, leading to additional processing delay and potential failure in HARQ-ACK feedback, resulting in resource waste and increased energy consumption.
Innovation Solution
A resource scheduling method where eRedCap terminals report their parallel PDSCH processing capability to the network device, allowing the network to schedule PDSCHs accordingly, avoiding multiple processing and delay issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If eRedCap terminals process multiple PDSCH channels in parallel, then resource utilization improves, but processing delay increases beyond acceptable thresholds
Solution Approach 1:
The patent implements dynamic parallel processing capability indication, where the terminal device adaptively reports its parallel PDSCH processing capacity to the network device. This allows the system to dynamically adjust the number of parallel PDSCH channels based on actual terminal capabilities and network conditions, optimizing resource utilization while maintaining acceptable processing delays within the 25/12 RB bandwidth constraint.
2Productivity
If eRedCap terminals process multiple PDSCH channels in parallel, then throughput increases, but HARQ-ACK feedback reliability decreases due to timing constraints
Solution Approach 1:
The patent establishes a feedback mechanism where the terminal device reports its parallel PDSCH processing capability to the network device. The network device uses this feedback information to appropriately configure the number of parallel PDSCH channels, ensuring that HARQ-ACK feedback can be generated and transmitted within required timing constraints, thus maintaining feedback reliability while optimizing throughput.
3Productivity
If eRedCap terminals process multiple PDSCH channels in parallel, then data transmission efficiency improves, but energy consumption increases
Solution Approach 1:
The patent changes the parameter of parallel processing capacity by having the terminal device indicate its specific parallel PDSCH processing capability to the network device. This enables the system to optimize the number of parallel channels according to actual needs, improving data transmission efficiency while avoiding excessive energy consumption by not over-provisioning parallel processing resources beyond what the terminal can effectively utilize.

AI summary
The present disclosure provides a resource scheduling method and apparatus. In response to an enhanced reduced capability (eRedCap) terminal having a first capability, the eRedCap terminal reports to a network device the number of parallel unicast physical downlink shared channels (PDSCHs) supported by the eRedCap terminal; or, in response to the eRedCap terminal not having the first capability, the eRedCap terminal does not report to the network device the number of the parallel unicast PDSCHs supported by the eRedCap terminal, wherein the first capability comprises the capability of the eRedCap terminal to process parallel unicast PDSCHs. According to the solution provided by the present disclosure, an eRedCap terminal uploads the number of parallel unicast PDSCHs supported by the eRedCap terminal, so that a base station learns the capability of the eRedCap terminal to process parallel unicast PDSCHs, thereby reasonably scheduling the unicast PDSCHs of the eRedCap terminal.
