Cyclic Parameter Fixing in Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In data transmission processes where the network side cannot determine the transport block size required by the terminal, it leads to high processing complexity and overheads for the network device due to varying cyclic parameters, especially when the terminal selects a transport block size less than the maximum allowed, causing inefficient resource utilization and increased power consumption.
Innovation Solution
The network device sends information about a fixed repetition quantity R1, allowing the terminal to determine a cyclic parameter L based on R1, which remains constant regardless of the selected transport block size, enabling the network device to accurately receive data without assuming different values of L, thus reducing processing complexity and overheads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network device processes data reception by assuming different values of cyclic parameter L for different transport block sizes, then it can handle diverse data transmission scenarios, but the processing complexity and overheads increase
Solution Approach 1:
The patent applies parameter changes by fixing the cyclic parameter L to a predetermined value regardless of the transport block size. This eliminates the need for the network device to process multiple L values, thereby reducing processing complexity while maintaining the ability to handle diverse data transmission scenarios through other adaptive mechanisms
Solution Approach 2:
The patent extracts the cyclic parameter L from the variable parameters and makes it fixed. By separating L from the transport block size dependency, the network device no longer needs to adjust L based on different data sizes, thus reducing overheads and processing complexity
2Productivity
If the terminal selects a transport block size less than the maximum allowed to avoid resource waste, then resource utilization improves, but the network device still faces high processing complexity due to varying cyclic parameters
Solution Approach 1:
The patent changes the status of cyclic parameter L from a variable to a fixed predetermined value. This allows terminals to select optimal transport block sizes for resource efficiency while the network device maintains consistent processing complexity by always using the same L value

AI summary
This application relates to the field of communications technologies, and provides a data transmission method and a communications apparatus, to reduce complexity and overheads of data reception performed by a base station. The method includes: receiving information about a repetition quantity R1 corresponding to Tmax, where Tmax is a maximum transport block size allowed to be used to transmit data; determining a cyclic parameter L based on R1, where the cyclic parameter L indicates that content carried in each of a plurality of time units to which a transport block used to transmit the data is mapped is repeated in L consecutive time units, and wherein a size of the transport block used to transmit the data is Ts, and Ts < Tmax; and transmitting the data based on the cyclic parameter L.
