Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.

step 104: in response to the first link quality, the first relay node determines whether the first link quality is below a link quality threshold; it should be understood by those skilled in the art that the link quality threshold is related to the data transmission speed (how many retransmissions) and the stability, and if the link quality threshold is very low, the number of retransmissions becomes large, and the stability of data transmission is degraded, which is beneficial to avoid switching the relay node so as to avoid increasing the load of other nodes, and at the same time avoid signaling overhead during switching, and a "low link quality threshold" is suitable for some data with low delay requirement because such data has low requirement on transmission stability.

Step 105: if the first link quality is judged to be lower than the threshold value of the link quality, the first relay node continues to judge the operation mode of the first relay node;

step 106: if the operation mode of the first relay node is judged to be the first operation mode, the first relay node sends a link quality indicator to the mobile terminal, wherein the link quality indicator indicates that the first link quality is lower than a link quality threshold value to the mobile terminal;

step 107: in response to receiving the link quality indicator, listening, by the mobile terminal, for a synchronization signal and system information transmitted by the third relay node;

step 108: determining, by the mobile terminal, a resource for transmitting a random access preamble based on the synchronization signal transmitted by the third relay node and the system information in response to monitoring the synchronization signal transmitted by the third relay node;

step 109: transmitting, by the mobile terminal, the random access preamble to the third relay node in response to determining the resources for transmitting the random access preamble;

step 110: determining, by the third relay node, a transmission mode of the third relay node in response to receiving the random access preamble;

step 111: and if the transmission mode of the third relay node is judged to be the first mode, the third relay node sends a first PDCCH message to the mobile terminal at the first time point, wherein the first PDCCH message indicates PDSCH resources used for sending a random access response, PDSCH resources used for sending a first copy of the random access response and PDSCH resources used for sending a second copy of the random access response to the mobile terminal, and the random access response at least comprises uplink authorization.
