Fig. 3-1 is a kind of flow chart of resource regulating method shown in the embodiment of the present invention, and the present embodiment is with the resource tune Degree method is applied to illustrate in implementation environment shown in fig. 1.The resource regulating method may include the following steps:

Step 301, UE sends the measurement data such as SRS to base station.

When using resource regulating method provided in an embodiment of the present invention, SRS and CQI can be sent from UE to base station first Etc. measurement data.

Step 302, base station obtains priority list according to measurement data such as SRS, and priority list is needed for recording base station Carry out the scheduling of resource priority of each UE in the UE of scheduling of resource.

After obtaining various measurement data, such as CQI and SRS, base station can be according to the ginseng in these data for base station Number calculates the scheduling of resource priority of each UE for needing to carry out scheduling of resource, and base station can be by these scheduling of resource priority It charges in priority list, scheduling of resource can be carried out according to the priority list later, and it is excellent preferentially to meet scheduling of resource The high UE of first grade, in this way can be with the resource utilization of maximization network system.

It should be noted that base station is excellent according to the scheduling of resource that various parameters calculate each UE for needing to carry out scheduling of resource The algorithm of first grade can be determined that the algorithm of the base station of different vendor's production may be different by base station.

Step 303, base station obtains the time difference of current time and each UE the last time at the time of send SRS.

After obtaining priority list, base station available current time and each UE the last time send SRS's The time difference at moment.At the time of current time is that base station will carry out scheduling of resource.Since the measurement amount in SRS is sent from UE With time change at the time of SRS, thus the time difference can react the variation journey of the measurement amount in SRS to a certain extent Degree.

It should be noted that UE can periodically to base station send SRS, the SRS sending cycle can by base station come into Row setting, and after the SRS sending cycle of base station sets UE, usually all no longer change before UE and base station are disconnected.

It should be noted that base station may send different at the time of SRS from UE at the time of receiving SRS, but base station can be from The sending instant of the SRS is obtained in received SRS.

In addition, SRS sending cycle is longer, then base station be able to carry out the UE of scheduling quantity it is more, the measurement result of SRS Timeliness it is weaker；SRS sending cycle is shorter, and the timeliness of the measurement result of SRS is stronger, but SRS sending cycle compared with In short-term, when thering are other UE to need access base station, since, there may be influence, base station may just need between the SRS of different UE transmission It adjusts the SRS sending cycle of existing UE or refuses the access of the UE.

Illustratively, as shown in figure 3-2, illustrating schematic diagram for the time difference, each small box represents a subframe, Length is 1 millisecond (ms), needs to carry out the UE of scheduling of resource₁And UE₂SRS sending cycle be 10ms, then current time 13 away from From UE₁12 time difference is 2ms, 13 distance UE of current time at the time of the last time sends SRS₂The last time send SRS when The time difference for carving 11 is 7ms, 13 distance UE of current time₂14 time difference is 3ms at the time of sending SRS next time.

Step 304, base station estimates the channel matter at current time according to the variation of the channel quality of the last SRS sending cycle of UE Amount.

It base station, can be according to any UE upper after obtaining each UE corresponding time difference for needing to be scheduled The channel quality at current time of the UE in this SRS sending cycle is estimated in variation in a SRS sending cycle, wherein channel matter Amount is a measurement amount changed over time in SRS.
