Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Receiver communication devices struggle to determine the PDU set error rate due to incomplete or incorrectly received PDU sets in wireless communication systems.
Innovation Solution
A method and apparatus for wireless communication that enable the receiver communication device to determine the PDU set error rate by receiving first information from the sender communication device, which includes second information, the number of PDU sets, and the number of unsuccessfully transmitted PDU sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the receiver communication device attempts to determine PDU set error rate based on received data only, then the device complexity is reduced, but the measurement precision deteriorates because the receiver cannot accurately determine the error rate without sender information about transmitted PDU sets
Solution Approach 1:
The patent introduces an information message as an intermediary carrier that transmits PDU set transmission status from the sender to the receiver. This message contains critical information about which PDU sets were successfully transmitted, enabling the receiver to accurately calculate error rates without directly accessing the sender's transmission records, thus resolving the contradiction between device complexity and measurement precision
2Measurement precision
If the sender communication device transmits detailed information about each PDU set transmission status, then the measurement precision of error rate determination is improved, but the quantity of transmitted data increases
Solution Approach 1:
The patent extracts only the essential information needed for error rate calculation from the complete transmission status data. Instead of transmitting full details about each PDU set, the sender extracts and transmits only the transmission status indicators and PDU set identifiers that the receiver needs to compute the error rate, thereby reducing transmitted data volume while maintaining measurement precision
3Measurement precision
If the receiver communication device requests comprehensive transmission status information from the sender, then the measurement precision of PDU set error rate is improved, but the loss of time increases due to additional communication overhead
Solution Approach 1:
The patent implements preliminary action by having the sender proactively transmit the PDU set transmission status information along with the data transmission itself, rather than waiting for the receiver to request this information. This anticipatory transmission of status information eliminates additional communication rounds and reduces the time required for the receiver to determine error rates while maintaining high measurement precision

AI summary
The present disclosure provides a method and apparatus for wireless communication. One example method includes receiving, by a first communication device, first information. The first information is used to determine a PDU set error rate corresponding to one or more PDU sets that a second communication device needs to transmit to the first communication device. The first information includes at least one of: second information corresponding to the one or more PDU sets, a number of the one or more PDU sets, or a number of unsuccessfully transmitted PDU sets in the one or more PDU sets.
