Abstract

The invention provides a data processing method, a configuration method and communication equipment. The data processing method applied to first communication equipment comprises the following steps: acquiring a network coding parameter; generating N coding sub-blocks of a first data block through a target layer according to the network coding parameters; and sending the N coding sub-blocks to a second communication device, wherein N is a positive integer. According to the invention, under the condition of ensuring the reliability of data transmission, the redundancy of data transmission can be reduced, so that the spectrum utilization rate can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to a data processing method, a configuration method, and a communication device. Background technique [0002] At present, in carrier aggregation (Carrier Aggregation, CA) or dual connectivity (Dual connectivity, DC) communication systems, in order to improve the reliability of data transmission, packet duplication (Packet Duplication), also known as packet data convergence protocol, is generally used. (Packet Data Convergence Protocol, PDCP) duplication (Duplication) method for data transmission, that is, using two independent transmission paths to transmit the same PDCP data packet (PDCP Packet), such as transmission on two different carriers or two wireless connections same packet. [0003] Although the above method can improve the reliability of data transmission to a certain extent, it will cause high redundancy of data transmission, result...
