Embodiment 1

[0054] In this embodiment, the spectrum resource of the backhaul link allocated to the RN is the same as the spectrum resource used by the RN's current access link, and the configuration method of the backhaul link resource in wireless resource reconfiguration is implemented, as shown in image 3 As shown, the method includes the following steps:

[0055] Step 201: The DeNB sends a backhaul link resource reconfiguration command to the RN. According to the spectrum resource of the backhaul link allocated to the RN is the same as the spectrum resource used by the RN's current access link, the backhaul link resource reconfiguration command includes the backhaul link Spectrum configuration information and backhaul link subframe configuration information;

[0056] The backhaul link resource reconfiguration command may be included in the RRC connection reconfiguration message and sent to the RN, or may be sent to the RN separately;

[0057] The backhaul link spectrum configuration ...

Embodiment 2

[0063] In this embodiment, the spectrum resources of the backhaul link allocated to the RN are different from the spectrum resources used by the RN's current access link, and the method for configuring the backhaul link resources in wireless resource reconfiguration is implemented, as shown in Figure 4 As shown, the method includes the following steps:

[0064] Step 301: The DeNB sends a backhaul link resource reconfiguration command to the RN. According to the difference between the spectrum resources of the backhaul link allocated to the RN and the spectrum resources used by the RN's current access link, the backhaul link resource reconfiguration command includes the backhaul link Spectrum configuration information;

[0065] The backhaul link resource reconfiguration command can be included in the RRC connection reconfiguration message and sent to the RN, or can be sent to the RN separately; the spectrum information of the backhaul link allocated for the RN includes frequen...

Abstract

The invention discloses a configuration method and a system of a backhaul link resource in wireless resource reassortment. The upper layer network node of an access point (AP) confirms the configuration information which is sent to the AP and is included in the backhaul link resource reassortment according to whether the spectrum resource which is used for allocating the backhaul link resource for the AP and the spectrum resource of the current access link of the AP are the same. The AP conducts resource reassortment according to the configuration information of the backhaul link resource in the wireless resource reassortment order after receiving an order of the backhaul link resource reassortment. The invention further discloses a configuration system of the backhaul link resource in the wireless resource reassortment. By means of the configuration method and the system of the backhaul link resource in the wireless resource reassortment, the problems that the resource reassortment of the backhaul link is still not clear and the how to configurate a backhaul link subframe of an existing art can be solved.

Description

technical field [0001] The present invention relates to wireless communication technology and cognitive radio technology, in particular to a method and system for configuring backhaul link resources in wireless resource reconfiguration. Background technique [0002] Current access nodes (AP, Access Point) mainly include the following types: relay node (RN, Relay Node), pico cell base station (Femto NB), micro cell base station (Pico NB) and home base station (home NB). Some of these access nodes can be directly connected, and the link between the directly connected access nodes is called a backhaul link, and the link between the AP and the terminal is called an access link. [0003] Taking the RN node as an example, with the continuous development of wireless communication technology, the Third Generation Partnership Project (3GPP) Long Term Evolution Advanced (LTE-A) system can provide downlink 100Mbit / s and uplink 50Mbit / s under 20MHz spectrum bandwidth. The peak rate imp...
