Embodiment Construction

[0029] In order to save the research and development cost of the LTE-A system, in the embodiment of the present invention, in the LTE-A system, the radio link control sublayer (Radio Link Control, RLC) of the network node receives the packet data concentration protocol sublayer (Packet Data Convergence A number of radio link control service data units (Radio Link Control: RLC Service Data Unit, RLC SDU) issued by the Protocol, PDCP), the RLC SDU includes communication data of at least one communication peer; the RLC layer according to the preset The scheduling strategy allocates the received RLC SDUs to each carrier, and sends the allocated RLC SDUs to the communication peer through each protocol layer below this layer.

[0030] It can be seen from the above description that the inventive points of the embodiments of the present invention include: data offloading at the RLC layer, that is, at the RLC layer of the network node, the data belonging to the same communication peer i...

Abstract

The invention discloses a method for data distribution in a LTE-A system, which comprises that: an RLC layers of network nodes receive a plurality of RLC SDUs transmitted by PDCP layers, wherein the RLC SDUs comprise communication data of at least one communication opposite terminal; and the RLC layers distribute the plurality of received RLC SDUs to carriers according to preset scheduling policies and transmit plurality of distributed RLC SDUs to the communication opposite terminals through protocol layers below the layer. Thus, compared with the LTE system, the LTE-A system has the advantages of avoiding the change of the protocol design and equipment of the protocol layers below the RLC layers of the network nodes and consequently saving research and development cost to a great extent. In addition, the invention also discloses a communication device and the LTE-A system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data distribution method, device and system in an LTE-A system. Background technique [0002] As technology develops, the need for increased data rates in wireless communication systems continues to grow. In the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP), in order to meet the increasing data rate requirements, as an evolution version of the Long Term Evolution (LTE) system, Long Term Evolution-Advanced (Long Term Evolution-Advanced) The Advance LTE-A) system needs to support a maximum bandwidth of 100MHz. At present, for this goal, the LTE-A system adopts carrier aggregation technology to achieve bandwidth expansion under the premise of considering reasonable UE complexity. The so-called carrier aggregation technology is to aggregate multiple existing LTE carriers, thereby Realize the simultaneous use of continuous spectrum and discontinuou...
