The adjacent TDD sub-district of hypothesis in the consolidated network is time synchronized in the present embodiment, and the neighbor cell of mentioning here can be with neighbor cell frequently, also can be adjacent neighbor cell frequently; Simultaneously can be the neighbor cell (for example all being Macro (grand) sub-district) with layer, also can be the neighbor cell (for example Macro sub-district and femto (femto) sub-district, perhaps Macro sub-district and Pico (little) sub-district) that layering is disposed.
Referring to Fig. 3, the main method flow process of transmitting and scheduling is as follows in the present embodiment:
Step 301: the base station obtains the uplink-downlink configuration information of neighbor cell.Concrete, the base station can obtain the uplink-downlink configuration information of neighbor cell by modes such as network interface Signalling exchanges.
Whether simultaneously step 302: the base station is according to the uplink-downlink configuration information of local area and the uplink-downlink configuration information of neighbor cell, judge between local area UE and the neighbor cell UE the different transmission of travel direction.The base station judges whether local area and neighbor cell adopt identical configuration to get final product, and the configuration sequence number is different just to exist the situation of carrying out the different directions transmission simultaneously.
Step 303: when between local area UE and the neighbor cell UE during the different transmission of travel direction simultaneously, the base station judges whether described local area UE is positioned at the cell edge near described neighbor cell.When travel direction is identical simultaneously between local area UE and the neighbor cell UE transmission, process ends.
Step 304: when described local area UE is positioned at cell edge near described neighbor cell, the base station to the up-downgoing transmitting and scheduling of the described local area UE of major general to carrying out simultaneously on the subframe of equidirectional transmission with neighbor cell UE.When described local area UE is not interfered, can continue UE to be dispatched according to current configuration.
Multiple specific implementation is arranged in step 303, as the base station judge UE whether be in local area and as described in the edge of neighbor cell, if determine that then described local area UE is positioned at the cell edge near described neighbor cell.Perhaps, the measurement result that reports by described local area UE of base station judges whether described local area UE is positioned at the cell edge near described neighbor cell.Can determine that the technology whether described local area UE is positioned near the cell edge of described neighbor cell all is applicable to present embodiment.Wherein, the base station obtains the positional information of base station of described neighbor cell and the positional information of described local area UE by locate mode, and judges according to the positional information of the base station that obtains and the positional information of described local area UE whether UE is in the edge of local area and described neighbor cell.Perhaps, the base station is by Operation and Maintenance entity (Operation and Maintenance, OAM) obtain described neighbor cell the base station positional information and obtain the positional information of described local area UE by locate mode, and judge according to the positional information of the base station that obtains and the positional information of described local area UE whether UE is in the edge of local area and described neighbor cell.Concrete locate mode has: AOA+TA (Angle of Arrival+Timing advance, the angle of arrival and timing advance) or OTDOA (Observed Time Difference Of Arrival, the time of advent is poor) etc.
The base station judges whether UE is subjected to interference that multiple specific implementation is also arranged, the signal quality value preset first threshold (for example 0dB) of local area as described in whether the signal quality value of neighbor cell exceeded as described in local area UE reported as described in judging as the base station, if, then the signal of neighbor cell is stronger, determines that described local area UE is positioned at the cell edge near described neighbor cell.Perhaps, the base station judges that whether the absolute value of the difference between the signal quality value of the signal quality value of the described neighbor cell that described local area UE reports and described local area is less than preset second threshold value (for example 3dB), if, then the signal strength signal intensity of local area and neighbor cell is suitable, determine that UE is in cell edge, think that described local area UE may be interfered.Perhaps, the base station judge described local area UE to the path loss values of described neighbor cell low default the 3rd threshold value (for example 0dB) of path loss values of described local area, if determine that then described local area UE is positioned at the cell edge near described neighbor cell.Perhaps, the base station judge described local area UE to the absolute value of the difference between the path loss values of the path loss values of described neighbor cell and described local area whether less than the 4th threshold value of presetting (for example 3dB), if determine that then described local area UE is positioned at the cell edge near described neighbor cell.Wherein, signal quality comprises RSRP (Reference Signal Received Power, Reference Signal Received Power) or RSRQ (Reference Signal Received Quality, Reference Signal Received Quality) etc.The path loss of described local area can obtain by local area reference signal transmitting power being deducted the local area signal quality (as RSRP) that UE reports, and described local area UE can deduct the neighboring cell signal quality that UE reports by adjacent area reference signal transmitting power to the path loss of described neighbor cell and obtain.The reference signal transmitting power of adjacent area can be notified to local area by the network interface between the sub-district.
There is multiple scheduling mode the base station in the step 304, as the base station with as described in the base station of neighbor cell adopt identical uplink-downlink configuration.Concrete, the base station negotiate of base station and described neighbor cell is determined identical uplink-downlink configuration.For example, a kind of configuration is determined in the base station, and the sequence number that will dispose sends to the base station of described neighbor cell, acknowledge message is returned in the base station of described neighbor cell then, perhaps a kind of configuration is determined in the base station of described neighbor cell, and the sequence number that will dispose sends to the local area base station, and acknowledge message is returned in the local area base station.Perhaps, the uplink-downlink configuration of acquiescence is all adopted in the base station of base station and described neighbor cell.Wherein, there is identical acquiescence uplink-downlink configuration the local area base station with the base station configuration of described neighbor cell.
Perhaps, on the subframe of constant transmissions, the subframe of constant transmissions comprises fixedly sub-frame of uplink and fixedly descending sub frame with the up-downgoing transmitting and scheduling of described local area UE in the base station.For example downlink transmitting and dispatching is fixed as in each radio frames on the descending subframe 0,1,5,6, and the uplink scheduling is fixed as in each radio frames on the subframe 2,7 of uplink.As shown in Figure 4, the Macro base station find MUE (UE in the macrocell) may and HeNB UE (UE Home eNodeB under) between produce the cross time-slot interference, then with in the descending sub frame 0,1,4,5,6,9 of its descending scheduling in radio frames, uplink scheduling is in sub-frame of uplink 2,7.
