SYSTEM, RECEIVING DEVICE, AND METHOD

摘要

A system includes a transmitting device and a receiving device, wherein the transmitting device is configured to transmit a data group including a plurality of data blocks, each of the plurality of data blocks includes a first error check code, and the data group includes a second error check code, and the receiving device is configured to, based on the second error check code, determine whether an error is present in the data group, when it is determined that the error is present in the data group, determine, based on the first error check code, in which data block of the plurality of data blocks the error is present, and when the error is present in a first data block of the plurality of data blocks, transmit, to the transmitting device, a request for retransmission of the first data block among the plurality of data blocks.

1. A system comprising:
a transmitting device including a first memory and a first processor coupled to the first memory; and a receiving device including a second memory and a second processor coupled to the second memory, wherein the first processor is configured to transmit a data group including a plurality of data blocks, each of the plurality of data blocks includes a first error check code, and the data group includes a second error check code, and the second processor is configured to:
receive the data group from the transmitting device,based on the second error check code, determine whether an error is present in the data group,when it is determined that the error is present in the data group, determine, based on the first error check code, in which data block of the plurality of data blocks the error is present, andwhen the error is present in a first data block of the plurality of data blocks, transmit, to the transmitting device, a request for retransmission of the first data block among the plurality of data blocks.
