Problems solved by technology

[0039] To sum up, in the resource / authorization method provided by the prior art, the eNodeB determines the uplink and downlink resource scheduling / authorization information and the uplink and downlink MCS mode according to the uplink channel information between the UE and the eNodeB, that is, the eNodeB serves the RN The scheduling / granting of the uplink and downlink resources within the range is based on the uplink channel between the UE and the eNodeB. However, in practical applications, the uplink and downlink traffic channels of the UE within the service range of the RN do not pass through the uplink and downlink channels between the UE and the eNodeB. The channel is directly transmitted, but forwarded by the RN. It can be seen that the power control determined according to the uplink channel between the UE and the eNodeB, and the resource scheduling / granting method may not be able to accurately adapt to the uplink and downlink channels between the UE and the RN. thus degrading the wireless performance of the system

Embodiment Construction

[0069] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0070] Figure 4 It is a flowchart of a resource scheduling / authorization method provided by the present invention. Such as Figure 4 As shown, the method includes the following steps:

[0071] Step 401, the RN obtains the uplink channel information between the UE and the RN according to the received SRS signal from the UE, and reports the uplink channel information to the eNodeB.

[0072] In step 402, the eNodeB determines the downlink / uplink MCS mode and resource scheduling / granting information according to the uplink channel information, and notifies the UE of the resource scheduling / granting information.

[0073] The present invention will be described in detail through two embodiments below.

Abstract

The present invention discloses a resource scheduling / authorization method, which includes: RN obtains uplink channel information between UE and RN according to received SRS signal from UE, and reports uplink channel information to eNodeB; eNodeB according to the For uplink channel information, determine the downlink / uplink modulation and coding MCS mode and resource scheduling / granting information, and inform the UE of the resource scheduling / granting information. By adopting the method, the wireless performance of the system can be improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a resource scheduling / authorization method. Background technique [0002] With the development of wireless communication technology, wireless relay technology has been widely valued, such as the long-term evolution (LTE) system proposed by the third generation mobile communication system standardization partnership project (3GPP), and the global interconnection for microwave access (WiMAX) system and other major systems are mentioned. In the LTE system and WiMAX system, the relay node (RN) is an intermediate node between the base station (eNodeB) and the user equipment (UE), which increases system coverage and system capacity by forwarding uplink and downlink traffic channels. figure 1 It is a schematic diagram of the relationship among RN, UE and eNodeB. The present invention is applied to LTE system, WiMAX system and other situations where relay node RN is applied. [000...
