Uplink Scheduling Information Generation for Wireless Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current uplink data transmission methods in communications devices are inefficient due to the need to establish RRC and non-access stratum connections, which slows down the sending of uplink data.
Innovation Solution
Generating uplink scheduling information, including modulation and coding schemes, prior to data transmission, allowing direct sending of data without establishing connections or sending scheduling requests, thereby improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RRC connection and non-access stratum connection are established before sending uplink data, then connection reliability is improved, but uplink data sending efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-establishing RRC and non-access stratum connections before uplink data arrives at the buffer. This ensures connections are ready in advance, eliminating connection establishment delays when data needs to be sent, thus improving uplink data sending efficiency while maintaining connection reliability.
2Reliability
If scheduling request is sent before uplink data transmission, then resource allocation reliability is improved, but transmission delay increases
Solution Approach 1:
The patent applies preliminary action by performing resource allocation and generating uplink scheduling information before uplink data arrives at the buffer. This advance preparation eliminates the need to send scheduling requests when data is ready to transmit, thereby reducing transmission delay while ensuring reliable resource allocation.
3Reliability
If connection establishment and scheduling request procedures are performed, then transmission reliability is improved, but uplink data sending efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by completing connection establishment and generating scheduling information before uplink data arrives at the buffer. This advance preparation ensures all necessary procedures are completed beforehand, allowing immediate data transmission without procedural delays, thus improving uplink data sending efficiency while maintaining transmission reliability.
4Reliability
If RRC connection and non-access stratum connection establishment is required, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by establishing RRC and non-access stratum connections before uplink data arrives at the buffer. This advance setup ensures connections are ready when needed, reducing the frequency of connection establishment operations and simplifying connection management while maintaining communication reliability.
