In the propagation delay time between described eNB and the described RN less than described eNB during the twice of the propagation delay time during in the transmission of the distance of the radius of residential quarter, place, with last time period of described the first data time section as first free time section, described first free time section length be not less than time period of the propagation delay time between described eNB and the described RN;

Described the second time period determination module is used for:

In the propagation delay time between described eNB and the described RN less than described eNB during the twice of the propagation delay time during in the transmission of the distance of the radius of residential quarter, place, with the previous time period of described the second data time section as second free time section, described second free time section length be not less than the twice of the propagation delay time of described eNB when the distance transmission of the radius of residential quarter, place;

7. a transmission period that utilizes claim 1 to determine carries out the method for transfer of data, it is characterized in that the method comprises:

Trunking RN sends the data of access link relay link by the transmitting time section in the first data time section in the first corresponding multicast single frequency network MBSFN subframe;

Base station eNB receives the data of access link relay link by the time of reception section in the second data time section in the second corresponding multicast single frequency network MBSFN subframe.

8. a transmission period that utilizes claim 1 to determine carries out the system of transfer of data, it is characterized in that this system comprises:

Trunking RN is used for the data by the transmission of the transmitting time section in the first data time section of the first corresponding multicast single frequency network MBSFN subframe access link relay link;

Base station eNB is used for the data by the reception of the time of reception section in the second data time section of the second corresponding multicast single frequency network MBSFN subframe access link relay link.
