Abstract

Embodiments of this application disclose a data processing method and an apparatus thereof. The method includes: processing, by a network device, to-be-transmitted data to obtain a data distribution manner, where the processing includes at least one of interleaving processing and mapping processing that is performed in a mapping sequence; the data distribution manner is used to indicate distribution of data from a same code block; and when the processing includes only mapping processing performed in a mapping sequence, the mapping sequence does not include a mapping sequence in which space-domain mapping is first performed, frequency-domain mapping is then performed, and time-domain mapping is finally performed; sending, the to-be-transmitted data distributed in the data distribution manner; receiving, by a terminal device, processed to-be-transmitted data; and determining, a data distribution manner, and performing de-processing on the processed to-be-transmitted data in the data distribution manner, to obtain the to-be-transmitted data.

Dependent claims

A data processing method, comprising:

receiving, by a terminal device, received data, wherein the received data is distributed from to-be-transmitted data of a code block in a data distribution manner;
determining, by the terminal device, the data distribution manner, wherein the data distribution manner is used to indicate that the to-be-transmitted data from the same code block is centrally distributed on at least one consecutive time domain symbol of the received data;
and
processing, by the terminal device, the received data in accordance with the data distribution manner, to obtain the to-be-transmitted data, wherein
the processing comprises at least one of de-interleaving and demapping performed on the received data, and wherein when the processing comprises only demapping without de-interleaving, the demapping is performed in a demapping sequence selected from one of a plurality of sequences of space-domain mapping, frequency-domain mapping, and time-domain mapping that exclude a demapping sequence in which space-domain demapping is first performed, frequency-domain demapping is then performed, and time-domain demapping is finally performed.
