Abstract

The embodiment of the invention discloses a logical channel (LCH) method and a communication device. In the method, a first data radio bearer DRB of a terminal corresponds to a first LCH, the first LCH is used for transmitting packet data convergence protocol PDCP data corresponding to a source host node; wherein the method comprises: a first relay node generates configuration information of a second LCH corresponding to the first DRB, the second LCH is used for transmitting PDCP data corresponding to a target host node; and the first relay node sends the configuration information of the second LCH to the terminal, wherein the source host node and the target host node are respectively the source host node and the target host node switched by the first relay node or the second relay node, and the second relay node is a relay node on a link between the first relay node and the source host node.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a data processing method, a communication device and a communication system. Background technique [0002] Compared with the fourth-generation mobile communication system, the fifth-generation (fifth generation, 5G) mobile communication has more stringent requirements for various network performance indicators in all aspects. For example, the capacity index has been increased by 1000 times, wider coverage requirements and ultra-high reliability and ultra-low latency. The Integrated access and backhaul (IAB) system emerged as the times require. Through a large number of densely deployed nodes, it can provide flexible and convenient access and backhaul services for terminals and improve coverage to meet the more stringent requirements of 5G. Stringent performance indicators. [0003] In a relay system such as an IAB system, due to reasons such as link quality,...
