The embodiment of the present invention receives the uplink scheduling request that user equipment (UE) sends, then obtain modulation and coding strategy MCS value, MCS value is sent to UE, to make UE according to MCS value transmission upstream data and to send buffer status report, if the buffer status report instruction UE received need to send data, and determine that the adjustment number of times of MCS value does not exceed preset threshold value, then obtain MCS value, and MCS value is adjusted upward; MCS value after adjustment is sent to UE, sends upstream data to make UE according to the MCS value after adjustment.The present embodiment is after the uplink scheduling request sent according to UE is dispatched, data are sent if need, then in scheduling several times afterwards, MCS value is adjusted upward, thus promote the size of transmission block, under the prerequisite ensureing transmission quality, improve the uplink efficiency of UE.
In order to better the embodiment of the present invention is described, below the present invention is described in detail, specifically can consult Fig. 2, another schematic flow sheet of a kind of resource regulating method that Fig. 2 provides for the embodiment of the present invention.The resource regulating method that the present embodiment provides mainly comprises the following steps:
The uplink scheduling request that step 201, reception user equipment (UE) send;
Upstream data to be sent to eNB arrives UE buffer memory, and UE sends uplink scheduling request to eNB, and request eNB issues schedule information, and the schedule information that UE then can issue according to eNB sends upstream data, so far completes once up transmission.
The channel quality of step 202, acquisition UE, obtains MCS value according to channel quality, MCS value is sent to UE, and to make UE according to MCS value transmission upstream data and to send buffer status report, wherein, whether buffer status report is used to indicate UE and need to send data;
The channel quality of UE can obtain according to signal to noise ratio, wherein, because channel quality is dynamic change, when Practical Calculation channel quality, channel quality be signal to noise ratio and signal to noise ratio adjustment amount and.ENB obtains the channel quality of UE after receiving the uplink scheduling request of UE transmission, signal to noise ratio adjustment amount is now 0, then channel quality is signal to noise ratio.Wherein, the concrete obtain manner of signal to noise ratio see prior art, can repeat no more herein.
The corresponding relation of channel quality and MCS value can be kept in a table, and known channel quality is then by acquisition MCS value of tabling look-up.Should be understood that, the corresponding relation of channel quality and MCS value is default, as channel quality can be linearly relevant to MCS value, or certain specific functional relation, this is not specifically limited.
If the buffer status report instruction UE that step 203 receives UE transmission need to send data, then determine to transmit accuracy according to the upstream data received, according to the channel quality transmitting accuracy adjustment UE, and according to the channel quality determination MCS value obtained;
Buffer status report instruction UE need to send data, then eNB needs to continue to issue schedule information to UE, then need the channel quality redefining UE, thus gives UE distributing radio resource.The transmission accuracy of its upstream data that specifically can send according to UE determines the channel quality of UE, concrete, eNB receives the upstream data that UE sends, can checking data result, and namely the transmission accuracy of this upstream data is how many, if transmission accuracy is greater than default accuracy, then signal to noise ratio adjustment amount is adjusted upward, if transmission accuracy is not more than default accuracy, then signal to noise ratio adjustment amount is adjusted downwards, wherein, the channel quality of UE is that signal to noise ratio and signal to noise ratio adjustment amount add up.Wherein, default accuracy is not specifically limited.
For example, when the transmission accuracy of this upstream data is greater than 90%, then signal to noise ratio adjustment amount is increased by 0.01, if be not more than, then signal to noise ratio adjustment amount is deducted 0.09.
If the adjustment number of times of step 204 MCS value does not exceed preset threshold value, then MCS value is adjusted upward;
If the adjustment number of times of MCS value exceedes preset threshold value, then MCS value is not adjusted upward, directly this MCS value is sent to UE, adopt this MCS value to continue to send upstream data to make UE.
For example, receive the uplink scheduling request of UE at eNB after, UE the MCS value determined is sent to send upstream data to make UE, if buffer status report instruction UE need to send data, then redefine MCS value according to the accuracy of this upstream data received, this can determine that the adjustment number of times of MCS value is 0, if preset threshold value is 3, then do not exceed predetermined threshold value, then the MCS value redefined is adjusted upward, UE adopts the MCS value after adjustment to send upstream data, if buffer status report instruction UE need to send data, then redefine MCS value according to the accuracy of this upstream data received, this can determine that the adjustment number of times of MCS value is 1, do not exceed preset threshold value 3, then the MCS value redefined is adjusted upward, UE adopts the MCS value after adjustment to send upstream data, and according to above-mentioned steps by that analogy, until buffer status report instruction UE does not have data to be sent then process ends, or until determine that the adjustment number of times of MCS value exceedes preset threshold value then process ends.
Wherein, MCS value is adjusted upward, specifically comprises: according in step 204 obtain UE channel quality and adjust upward, and according to adjustment after channel quality obtain the MCS value after adjusting upward; Or obtain MCS value according to channel quality, and MCS value is adjusted upward.Concrete, several dB can be added, the MCS value of then tabling look-up after being adjusted to the channel quality of the UE obtained in step 204, value be adjusted upward to channel quality and is not specifically limited.Or table look-up to the channel quality of the UE obtained in step 204 and obtain MCS value, this MCS value then this obtained adds some values, specifically adjusts upward value to MCS value and is not specifically limited.
The channel quality such as, obtained in step 204 is 10dB, 10dB can be added 2dB, obtain 12dB, then acquisition MCS value of tabling look-up, or adopts 10dB to table look-up to obtain MCS value, then this MCS value is added 3 be adjusted after MCS value.Suppose that the MCS value that channel quality 10dB is corresponding is 3, the MCS value that channel quality 12dB is corresponding is 5, and the MCS value so adopting first method to obtain is 5, and the MCS value adopting second method to obtain is 6.
Step 205, by adjustment after MCS value send to UE, with make UE according to adjustment after MCS value send upstream data.
UE understands reporting buffer status report to eNB while transmission upstream data, eNB can continue to issue schedule information to UE or end scheduling flow according to this buffer status report, wherein, need to send data if buffer status report is UE, then return and perform step 203, until UE does not have data to be sent.
UE receives the MCS value after adjusting upward of base station transmission, then send upstream data according to the MCS value after this adjustment, because MCS value increases, and MCS value determines the size of transmission block, then adjust upward MCS value and improve transmission block size, improve the uplink transmission rate of UE in base station.
Embodiment of the present invention eNB is when the uplink scheduling request sent according to UE carries out secondary scheduling, MCS value is not adjusted, the accuracy that upstream data sends can be ensured, avoid retransmitting, if and send after uplink scheduling request at UE and also have other data to be sent, then in scheduling several times afterwards, MCS value is adjusted upward, upstream data transmitting efficiency can be improved while guarantee accuracy.

If UE need to send data, then perform step 305; If UE does not have data to be sent, then perform step 309, terminate scheduling flow.
Step 305, buffer status report instruction UE need to send data, and eNB determines the transmission accuracy of the upstream data that UE sends, and determines the channel quality of UE according to this transmission accuracy;
Wherein, if transmission accuracy is greater than 90%, then signal to noise ratio adjustment amount is added 0.01, if transmission accuracy is not more than 90%, then signal to noise ratio adjustment amount is deducted 0.09, wherein, the channel quality of UE is that signal to noise ratio and signal to noise ratio adjustment amount add up.
Step 306, eNB judge whether the adjustment number of times of MCS value exceedes preset threshold value, if do not exceed, then obtain MCS value according to the channel quality of UE and adjust upward;
