Embodiment Construction

[0079] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0080] It can be seen from the background technology that the reason why the transmission performance of the RN is not high when the RN selects the DeNB is mainly that the DeNB is selected only according to the signal strength of the transmission data detected by the RN, without considering the backhaul link between the RN and the DeNB The size of the transmitted data capacity. However, the transmission data capacity of the backhaul link between the RN and the DeNB also has a decisive impact on the transmission performance of the RN.

[0081] Therefore, when the present invention selects DeNB for RN, according to the data capacity-related information of multiple neighboring cell base stations that meet the signal strength requirements of RN transmission...

Abstract

The invention discloses a method, a system and a device for selecting a donor eNB for a relay node. According to respectively acquired data capacity related information of a plurality of neighbouring eNBs meeting signal intensity requirement of data transmission of the relay node, and channel quality information of return links of the relay node and the plurality of neighbouring eNBs, available channel capacity of the return links between the neighbouring eNBs and the relay mode are respectively computed, then the neighbouring eNB with the return link of largest available channel capacity is taken as the donor eNB of the relay node to be accessed. The method improves the transmission performance of the relay node.

Description

technical field [0001] The present invention relates to the field of wireless communication systems, in particular to a method, system and device for selecting a donor cell base station of a relay node (RN). Background technique [0002] In order to cope with various complex wireless propagation environments and solve the coverage problem of future long-term evolution (LTE) network deployment, RN is standardized in the LTE-AR10 version of the third generation partnership project (3GPP). By adding an RN between the macro base station and the user terminal, the direct transmission link between the macro base station and the user terminal is divided into two sections: the wireless link between the macro base station and the RN is called the backhaul link, namely Un interface; the wireless link between the RN and the user terminal is called the access link, that is, the Uu interface, such as figure 1 The shown prior art provides a schematic structural diagram of an LTE system w...
