Uplink Data Block Generation for Multi-Carrier Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radio interface protocols are inefficient when applied to multiple carriers in wireless communication systems, leading to suboptimal data transmission and increased complexity in managing uplink frequencies.
Innovation Solution
A method and apparatus for generating data blocks on multiple uplink frequencies by determining the size of the data field to match the minimum allowed data transmission on each frequency, with the option to pre-generate RLC PDUs based on uplink grants, reducing complexity and ensuring suitable data amounts for transmission across multiple frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional radio interface protocols are applied to multiple carriers, then single carrier design simplicity is maintained, but data transmission efficiency deteriorates
Solution Approach 1:
The patent segments the data transmission process by determining data block sizes separately for each uplink frequency based on individual grants, then multiplexing these segmented blocks into a unified transmission structure. This allows efficient multi-carrier transmission while maintaining manageable complexity through modular processing.
Solution Approach 2:
The patent transitions from single-carrier sequential processing to multi-carrier parallel processing by introducing a frequency dimension. Data blocks are generated and multiplexed across multiple uplink frequencies simultaneously, improving throughput without proportionally increasing complexity through structured resource allocation.
2Reliability
If data block size is determined to match minimum allowed data across multiple frequencies, then transmission suitability is improved, but processing complexity increases
Solution Approach 1:
The patent performs preliminary determination of data block sizes by calculating the minimum allowed data across all uplink frequencies before actual transmission. This advance planning ensures transmission suitability is achieved while reducing real-time processing complexity through pre-computed parameters.
3Loss of time
If RLC PDUs are pre-generated for later TTI, then transmission readiness is improved, but memory and processing requirements increase
Solution Approach 1:
The patent implements partial pre-generation of RLC PDUs by creating data blocks based on minimum allowed data calculations rather than generating all possible transmission variants. This selective pre-generation reduces memory requirements while maintaining transmission readiness for the immediate next TTI.

AI summary
A method and apparatus of generating a data block for a plurality of uplink frequencies is provided. The apparatus determines a size of a data field of the data block so that each data block matches a minimum of a first amount of data and second amount of data. The first amount of data is allowed to be transmitted by a first grant on a first uplink frequency and the second amount of data is allowed to be transmitted by a second grant on a second uplink frequency. The apparatus generates at least one data block so that the amount of data in the generated data blocks is less than multiple times the minimum of the first amount of data and the second amount of data.
