Base Station Unit Format Indication for LTE Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing LTE system has only one unit format, which cannot meet the current demands of communications, leading to difficulties in data transmission efficiency as both the transmitter and receiver may not operate in the same format, resulting in potential reception failures.
Innovation Solution
A method and system that allow a base station to select and indicate one of multiple unit formats based on preset conditions, such as the type of user equipment, transmission rate, channel condition, and cell load, to ensure both the transmitter and receiver operate in the same unit format, thereby improving data transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple unit formats are introduced to meet diverse communication demands, then the adaptability of the system is improved, but the complexity of format selection and synchronization between transmitter and receiver increases
Solution Approach 1:
The patent applies parameter changes by introducing a format indication field that dynamically specifies which unit format is being used. This allows the system to adapt between different unit formats (e.g., LTE and LTE-A formats) by changing the format parameter indicated in the signaling, rather than requiring separate fixed configurations for each format type.
Solution Approach 2:
The patent introduces a format indication field as an intermediary element that mediates between the multiple unit formats and the receiver. This intermediary carries explicit format identification information, allowing the receiver to correctly interpret the transmitted data without needing to guess or assume the format, thus reducing the complexity of format synchronization.
2Ease of operation
If a single unit format is used in the system, then the simplicity of operation is maintained, but the efficiency of data transmission deteriorates due to inability to meet diverse communication demands
Solution Approach 1:
The patent applies universality by designing a unified signaling structure that can accommodate multiple unit formats through the format indication field. The same signaling framework serves both LTE and LTE-A format requirements, making the system multi-functional while maintaining operational simplicity through a consistent interface and procedure.
3Adaptability or versatility
If the receiver adopts a different unit format from the transmitter, then the flexibility of the receiver is demonstrated, but the reliability of data reception deteriorates due to format mismatch
Solution Approach 1:
The patent implements feedback by including explicit format indication information in the transmitted signaling. The receiver uses this feedback information to determine the correct format for interpreting the data, ensuring that the receiver's format selection matches the transmitter's format and thereby maintaining high reception reliability.

AI summary
The present invention discloses a method, system and apparatus for indicating a unit format. The method of the embodiment in the present invention includes that: according to a preset first selection condition, a base station selects a unit format from a plurality of unit formats; according to the preset correspondence between the unit format and an identifier, the base station determines the identifier corresponding to the selected unit format; and the base station sends the determined identifier to a user terminal, which instructs that the user terminal performs transmission according to the unit format corresponding to the identifier. With the present invention, a transmitting end and a receiving end can perform the operation by using the same unit format in the case of the plurality of unit formats, thereby improving the efficiency of data transmission.
