Embodiment Construction

[0056] In the embodiment of the present invention, the RN device determines traffic scheduling parameters according to the amount of downlink buffered data, and sends the traffic scheduling parameters to the base station, and the base station adjusts the data volume of the downlink backhaul link according to the traffic scheduling parameters. In the LTE-A system, the DeNB can control the amount of downlink data, avoiding the downlink data congestion of the RN device or the delay of the R-UE's downlink data due to the difficulty of controlling the amount of downlink data by the DeNB, thus reducing the downlink data Delay.

[0057] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0058] Such as figure 2 As shown, the system for adjusting data volume in the embodiment of the present invention includes: RN equipment 10 and base station 2( ).

[0059] The RN device 10 is configured to determine tr...

Abstract

The embodiment of the invention relates to the wireless communication technology, in particular to a method, system and device for adjusting data volume, aiming to solve the problem of the prior art that after the relay-node (RN) is introduced in a long term evolution-advanced (LTE-A) system, DeNB is difficult to control downlink data volume so that the congestion of the downlink data of the RN device and the delay of the downlink data of R-UE are easy to cause. The method of the embodiment of the invention comprises the following steps: the RN device determines traffic scheduling parameter according to the volume of the downlink cache data; the RN device sends the traffic scheduling parameter to a base station and requests the base station to adjust the data volume of the downlink backhaul link according to the traffic scheduling parameter. By adopting the method of the embodiment of the invention, the delay of the downlink data can be reduced and the efficiency of data transmission and the system performance can be increased.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method, system and device for adjusting data volume. Background technique [0002] After the LTE-A (Long Term Evolution-Advanced, long-term evolution upgrade) system introduces the Relay (relay) node, the following nodes, interfaces and links are defined, such as figure 1 as shown, [0003] Nodes include: [0004] Donor-eNB: An eNB that is wirelessly connected to the RN device, abbreviated as DeNB; [0005] Relay-Node: an entity existing between DeNB and UE, abbreviated as RN device; [0006] Relay-UE: UE that performs data interaction with RN equipment, abbreviated as R-UE; [0007] Macro UE: a UE that directly exchanges data with the DeNB. [0008] Interfaces include: [0009] Un interface: the interface between the RN device and the DeNB; [0010] Uu interface: interface between UE and RN equipment. [0011] Wireless links include: [0012] Backhaul link:...
