Title:
INFORMATION TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/202541
Kind Code:
A1
Abstract:
The present application relates to the technical field of wireless communications, and provides an information transmission method and apparatus, for use in reducing the amount of retransmitted data and reducing the transmission overhead. In the method, a transmitting device sends a first bit sequence to a receiving device. Optionally, the first bit sequence is an information bit sequence or the first bit sequence is an information bit sequence subjected to first coding. The transmitting receives a second bit sequence from the receiving device. The transmitting device sends a first code block to the receiving device, the first code block being obtained according to a first error pattern and a first check matrix. The first error pattern is determined according to the second bit sequence and the first bit sequence. On the basis of the solution, the transmitting device can determine and obtain the first error pattern in the last transmission, and can adaptively adjust the amount of retransmitted data by means of the first error pattern. Compared with the current retransmission solution, the present application can reduce the amount of data during retransmission, improve the channel utilization rate, and reduce the transmission overhead.
