Abstract

A method for data transmission based on a relay mobile communication system and an equipment thereof are provided by the present invention. The method includes: at least two transport planes are configured on the Un interface protocol stack of the relay equipment and the base station eNode B; the relay equipment and the eNode B transmit the data via at least two transport planes configured on the Un interface protocol stack. With the present invention, the throughput rate of the Un interface between the relay equipment and the eNode B in the relay mobile communication system is improved, and the time delay of the Un interface is reduced.

Dependent claims

A method for transmitting data based on a relay mobile communication system, comprising:

configuring at least two transmission planes on protocol stacks of Un interface of a relay device and an eNodeB;
and
the relay device and the eNodeB transmitting data over the at least two transmission planes configured on the protocol stacks of Un interface,
wherein one Media Access Control, MAC, Protocol Data Unit, PDU, is generated respectively in each of the transmission planes, and the data is transmitted in the generated MAC PDU,
and wherein the data is transmitted over the at least two transmission planes between which at least one protocol layer entity among an MAC layer entity, a Radio Link Control, RLC, layer entity and a Packet Data Convergence Protocol, PDCP, layer entity is shared;
or
the data is transmitted over the at least two transmission planes respectively through their own MAC layer entities, RLC layer entities and PDCP layer entities.
