NETWORK CODING METHOD AND COMMUNICATION APPARATUS

Title:

NETWORK CODING METHOD AND COMMUNICATION APPARATUS

Document Type and Number:

WIPO Patent Application WO/2021/160140

Kind Code:

A1

Abstract:

Embodiments of the present application provide a network coding method. The method can be applied in an integrated access and backhaul (IAB) network. The IAB network comprises an IAB donor and an access IAB node. The IAB donor comprises a donor distributed unit (DU) and a donor centralized unit (CU). The method comprises: the donor DU performs network coding operation on data of user equipment sent by the donor CU to generate a coding data packet; the donor DU sends the generated coding data packet to the access IAB node. According to the embodiments of the present application, the network coding function is introduced into the IAB network so as to improve the reliability of data transmission in an IAB system and reduce the data transmission delay.
