Since the base station of configuration ABS cannot send Physical Downlink Control Channel (physical to terminal device on the ABS Downlink control channel, PDCCH) message and Physical Downlink Shared Channel (physical downlink Shared channel, PDSCH) message, so if the second base station is corresponding by the resource location of the transfer resource of terminal device Sub-frame configuration be ABS, then the second base station will not send PDCCH message and PDSCH message on the ABS, so that on the ABS Terminal device not will receive the interference of business and control channel from the second base station, but may be subjected to from the second base station The interference of pilot signal, therefore may be implemented to reduce the interference that terminal device is subject to.

In step 302, when the second information is used to indicate the second base station for the resource location pair of the transfer resource of terminal device When the sub-frame configuration answered is the subframe of specified type, in alternatively possible implementation, the subframe of specified type is MBSFN Subframe, at this point, the transfer resource of terminal device is that MBSFN sub-frame includes when the transfer resource of terminal device is time-domain resource Whole PRB, when the transfer resource of terminal device is frequency domain resource, the transfer resource of terminal device is the portion that MBSFN sub-frame includes Divide PRB.By taking the transfer resource of terminal device is whole PRB that the subframe that sub-frame number is 1 includes as an example, the second information instruction the Two base stations by the corresponding sub-frame configuration of the resource location of the transfer resource of terminal device be MBSFN sub-frame when, indicate the second information Indicate the second base station by the sub-frame configuration of serial number 1 be MBSFN sub-frame.

Due to configuration MBSFN sub-frame base station cannot in the MBSFN sub-frame pilot signal transmitted, so if the second base Standing the corresponding sub-frame configuration of the resource location of the transfer resource of terminal device is MBSFN sub-frame, then the second base station will not be in Pilot signal transmitted in the MBSFN sub-frame, so that terminal device not will receive leading from the second base station in the MBSFN sub-frame The interference of frequency signal, but may be subjected to the interference of business and control channel from the second base station, therefore may be implemented to reduce The interference that terminal device is subject to.

In step 302, when the second information is used to indicate the priority-level of the transfer resource of terminal device, the second base station After receiving the above-mentioned first information and the second information, it will carry out dynamic I CIC, the second base based on the first information and the second information Description will be unfolded in the method for carrying out dynamic I CIC based on the first information and the second information of standing in the method for the second base station side.This It, can be by terminal device when the second information is used to indicate the priority-level of the transfer resource of terminal device in embodiment The priority-level of transfer resource is configured to height, so that the transfer resource that the second base station avoids using terminal equipment is better achieved Purpose.

Optionally, when the second information is used to indicate the priority-level of the transfer resource of terminal device, first base station is also It can determine interference information, and the interference information is sent to the second base station.Wherein, interference information include one of following information or Combination: RNTP, HII, OI of first base station.In the case, first base station is sent to the second base station the first information, the second letter For the second base station progress dynamic I CIC, the second base station is based on the first information, the second information and interference for breath and interference information Description will be unfolded in the method that information carries out dynamic I CIC in the method for the second base station side.

Step 303: first base station sends the first information and the second information to the second base station.

In step 303, when the second base station be first base station adjacent base station when, first base station can by with the second base station Between communication interface, the first information and the second information are sent to the second base station.Class of the embodiment of the present application to communication interface Type does not do any restriction, and communication interface is related to the standard of first base station or the second base station.For example, first base station and the second base station Between communication interface can be the X2 interface between base station in LTE system, at this time first base station will carry the first information and The message of second information is sent to the second base station, which can be existing X2 interface message, such as load balancing (load Information) message is also possible to the message newly defined in addition to X2 interface message.In another example when first base station and second Communication interface when base station connects 5G core net between first base station and the second base station can be the Xn between base station in 5G system Interface.

In step 303, when the second base station is not the adjacent base station of first base station, first base station can be set by core net It is standby that the first information and the second information are transmitted to the second base station.For example, first base station connects Evolved Packet Core When (evolved packet core, EPC), first base station can by with mobile management entity (mobile management Entity, MME) between S1 interface the message for carrying the first information and the second information is sent to MME, then MME should Message is transmitted to the second base station, which can be existing S1 interface message, such as initial user equipment (initial UE Message) message is also possible to the message newly defined in addition to S1 interface message.In the case, in order to allowing core net Equipment knows that the message for carrying the first information and the second information is destined to the second base station, which also needs to carry the second base station Mark.

In step 303, the first information and the second information can be and is sent to the second base station by same message, be also possible to The second base station is sent to by different message respectively, is not limited in the present embodiment.

When the second information is used to indicate the priority-level of the transfer resource of terminal device, so that the second base station carries out dynamic When ICIC, the first information and the second information are sent to the second base station by first base station may have delay, which should be shorter than The ICIC period.
