Problems solved by technology

[0004] The resource status reporting schemes in the prior art are all designed for eNB. Since the interfaces between eNB and RN are different, the resource status reporting scheme about eNB cannot be applied to the resource status reporting about RN.
In summary, there is currently no effective solution for reporting the resource status of the RN

Embodiment Construction

[0031] In the embodiment of the present invention, the relay device and the first base station integrate the resource status information of the Uu port and the Un port and send it to the second base station, thereby realizing the reporting of the resource status information, so that the second base station can grasp the load situation of the neighboring cell , to adjust parameters such as handover and cell reselection, so as to enable load balancing in the network, improve transmission efficiency and overall network performance.

[0032] see figure 1 , the communication system in this embodiment includes a first base station 101 , a second base station 102 and a relay device 103 . There is an X2 interface between the first base station 101 and the relay device 103, so the first base station 101 is a DeNB. There is an X2 interface between the second base station 102 and the first base station 101, but there is no direct interface with the relay device 103, and there may be an ...

Abstract

Disclosed are a method and a device for reporting the state of resources in a relay system, for use in achieving resource state reporting relating to the relay system. The method comprises: a first base station forwarding to the relay device a resource state report request transmitted by a second base station; the first base station receiving a piece of resource state information transmitted by the relay device; the first base station transmitting to the second base station a piece of resource state information relating to a Uu port and to a Un port. Also disclosed is the device for use in implementing the method.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for reporting resource status in a relay system. Background technique [0002] In the LTE-A (Long Term Evolution-Advanced, upgraded long-term evolution) system, a relay node (Relay Node, hereinafter referred to as RN) is introduced in order to improve system throughput and increase network coverage. The RN is connected to a base station (Donor Evolved Node B, DeNB) in a wireless manner. The interface between UE and RN is called Uu interface, and the interface between RN and DeNB for data transmission is called Un interface. see figure 1 As shown, the RN is indirectly connected to other base stations (eNBs) through its own DeNB. And the cells under the RN may be adjacent to the cells under other base stations. Wherein, the base station connected to the RN is called a DeNB, and the DeNB is a kind of eNB. [0003] In a Long Term Evolution (LTE) network, for the pur...
