Abstract: The present application provides methods for sending data and receiving data and a communication apparatus. Considering that error data blocks in wireless transmission usually comprise partially correct data packets, a scheme for sending data on the basis of a maximum delay constraint T is proposed. A sending end sends (T+B) data blocks, among which the first T data blocks are original data blocks, and the last B data blocks are B encoded data blocks. The number of encoded data packets in the encoded data blocks is flexibly controlled. A receiving end only needs a certain number of encoded data packets and the correct data packets in the error data blocks to perform joint decoding to then recover error data packets in the error data blocks. The solution of the present application may meet requirements of a communication system for a maximum delay T, while also reducing the number of encoded data packets, and releasing more wireless resources for other purposes to improve the utilization rate of the wireless resources, thereby improving the overall performance of the communication system. The solution may be applied to XR services or other services which have low latency requirements.
