Embodiment
Also in conjunction with the accompanying drawings the present invention is described in further detail below by specific embodiment.
The embodiment of the invention can realize based on the Node B ascending resource fast dispatch technology in the HSUPA technology.In the system that adopts the HSUPA technology, radio network controller (Radio NetworkController; Hereinafter to be referred as: RNC) be responsible on macroscopic view ascending resource being carried out control, Node B utilizes absolute grant channel (E-DCH Absolute Grant Channel; Hereinafter to be referred as: E-AGCH) distribute AG to adjust the SG of UE on a large scale, promptly the absolute limitations of the maximum operable ascending resources of UE can be distributed to corresponding UE to one or one group of UE.Node B is also by relative authorization channel (E-DCHRelative Grant Channel; Hereinafter to be referred as: E-RGCH) distribute RG to come the SG of adjustment UE among a small circle to UE, indication UE increases, keeps or reduces a relative quantity and obtains new SG on current SG basis.Node B has realized dispatching fast, in real time UE sends ascending resource from data to Node B in conjunction with the distribution of AG and RG.For UE, the SG of its acquisition is big more, and then uplink resources available is many more, and promptly message transmission rate is high more, and the transmitting power of UE also increases with the increase of SG simultaneously.
In the system that adopts the HSUPA technology, each Node B can corresponding one or more base station cells, UE may be under a plurality of base station cells coverings of one or more Node B simultaneously, base station cell can corresponding HSUPA Serving cell, the base station cell that can merge RG is called HSUPA Serving cell collection, base station cell outside HSUPA Serving cell collection can corresponding non-HSUPA Serving cell, and wherein, HSUPA Serving cell and non-HSUPA Serving cell all can distribute RG for UE.UE can receive the RG of a plurality of distribution, according to the strategy of setting RG is merged to calculate to obtain current RG, and then calculating obtains current SG.The RG that UE obtains from the HSUPA Serving cell can have three possibility values, be " rising ", " maintenance " and " decline ", usually can represent with numerical value "+1 ", " 0 " and " 1 ", represent the step value that on former SG, increases regulation respectively, keep former SG constant, and the step value that on former SG, reduces regulation.Wherein Gui Ding step value is by default, and can in use adjust the size of step value as the case may be.In non-HSUPA Serving cell, only there are two possibility values in RG, is " maintenance " and " decline ", can use numerical value " 0 " and " 1 " expression usually, and representative keeps former SG and reduce the step value of stipulating on former SG respectively.
The technical scheme of the embodiment of the invention also further realizes based on power control techniques.At code division multiple access (Code Division Multiple Access; Hereinafter to be referred as: CDMA) system, for example synchronous code division multiple access (Time Division-Synchronous Code DivisionMultiple Access of WCDMA or time-division; Hereinafter to be referred as: TD-SCDMA) in the system.The superiority of digital mobile communication system high power capacity is embodied in based on key technologies such as power controls.The purpose of power control is to make system under the prerequisite that keeps high quality communication, reduces transmitting power as far as possible, to reduce the interference that other Code Channel on the shared channel is caused.Adopt the WCDMA system of HSUPA technology, its up link and down link have all adopted the control of closed loop fast power.The uplink closed loop technology is the quality of Node B according to the uplink signal that receives from UE, produces the TPC that is used for power control and sends to UE, thus the uplink transmission power of control UE.To be UE produce the TPC that is used for power control according to the quality of the down link signal that receives from Node B to the downlink closed-loop power control techniques sends to Node B, thus the down transmitting power of control NodeB.The bid value of TPC can comprise two kinds usually, and promptly " increase setting power " and " reducing setting power " are generally represented with numerical value " 1 " and " 0 ".The signal quality that receives as the recipient is lower than to be set when requiring, the TPC that then sends " increase setting power " comes the requirement transmit leg to increase transmitting power, the signal quality that receives as the recipient is higher than to be set when requiring, and the TPC that then sends " reducing setting power " comes the requirement transmit leg to reduce transmitting power.TPC can be carried in each time slot periodically mutual between Node B and UE, so that it is optimal value that Node B and UE adjust transmitting power in real time, the frequency of interaction of TPC is higher, generally can reach per second 1500 times, and TPC adjusts the transmitting power basic value of determining according to SG.
Resource scheduling processing method first embodiment
Fig. 1 is the flow chart of resource scheduling processing method first embodiment of the present invention.As shown in Figure 1, the method for present embodiment can be realized by Node B, specifically comprise the steps:
TPC can reflect current channel quality, and the history value of TPC then can reflect the variation tendency of channel quality, and because the frequency of interaction of TPC between Node B and UE is higher, therefore can reflect variations basically in real time.In the present embodiment, Node B carries out ascending resource scheduling, when promptly adjusting the SG of UE, taken variations result into consideration according to the history value statistics acquisition of TPC, make the variation tendency of the consideration channel quality that ascending resource scheduling further can be real-time, therefore can distribute rational RG to adjust the SG of UE.Reasonably SG can improve the uplink throughput of UE, for example:
When certain UE is in deep fade during the phase, promptly may be because too far away or be in and cause the channel quality extreme difference in the screen apart from Node B, this moment is because poor signal quality, the successful decoding rate reduction between Node B and the UE.Existing Node B and UE can adopt the HARQ technology usually; stipulate according to agreement; the recipient can preserve data under the situation of decoding failure; and require transmit leg automatically according to HARQ type data retransmission; the recipient attempts decoding to the data combination that repeatedly retransmits according to the HARQ type together; retransmit the number of times restriction is not only arranged; and UE will occupy ascending resource to the data that Node B retransmits at every turn; though UE uploads new data according to the current SG that obtains; but can abandon the current SG of UE in UE in retransmission, the SG when still sending these data according to the first time retransmits.When successful decoding rate between Node B and the UE reduced, number of retransmissions will correspondingly increase, the data occupancy of re-transmission more ascending resource.At this moment, because UE is in during the deep fade, the TPC that network sends can continue to require UE rising transmitting power, the raising of UE transmitting power has increased the interference level to RTWP in the base station cell, the success decoding rate reduces on the contrary, and the data of newly uploading also need continuous re-transmission, form a kind of vicious circle, the data occupancy that retransmits a large amount of ascending resources, make the uplink throughput of UE significantly descend.The cycle that reports Node B as the re-transmission relevant parameters such as number of retransmissions of dispatching the factor is longer, general magnitude according to about 10 milliseconds sends to Node B, has bigger delay, be difficult to reflect in real time the variation tendency of current channel quality, especially the situation that changes above-mentioned vicious circle under the situation faster at quality of wireless channel more is prone to.According to the above analysis, if adopt the uplink scheduling method of prior art, then can keep even increase the SG that distributes to UE, increase transmitting power simultaneously, as long as the channel quality of UE does not improve, to be limited among the vicious circle the adjustment of the SG of UE and transmitting power, that is: transmitting power is big more, and signal disturbs big more, and successful decoding rate is low more, the ascending resource that data retransmission takies is many more, and the uplink throughput of UE descends.
When adopting the technical scheme of present embodiment, then when the SG of this UE is distributed in adjustment, just can utilize the statistical value of TPC, almost obtain the variation tendency of channel quality in real time, thereby avoid being absorbed among the above-mentioned vicious circle, reduce the re-transmission load of UE, improve the uplink throughput of UE.
On the contrary, if the situation that channel quality constantly improves adopts when having the ascending resource scheduling scheme now, owing to have bigger delay, Node B can not be that UE distributes more SG according to the variations of UE, has then hindered the increase of UE uplink throughput.The technical scheme of present embodiment is the situation of the continuous improvement of identification channel quality in real time then, thereby makes suitable adjustment, for UE distributes more SG, is beneficial to improve the uplink throughput of UE.
In the technical scheme of present embodiment, the mode of obtaining the TPC history value can have multiple, for example can carry out following step carry out the variations statistics according to the history value of TPC before:
When Node B gets access to the TPC that is received from or sends to UE, adopt First Input First Output to store in the memory of this UE correspondence respectively each TPC that receives or send, history value as TPC, each memory is corresponding with a UE respectively, and its capacity of storing TPC separately is at least and can stores two TPC.That is: corresponding each UE can be provided with two memories, and a memory can be described as line storage, is used to store the TPC that Node B is received from UE, and another memory can be described as down line storage, is used to store the TPC that Node B sends to UE.The TPC that is received from UE can be described as up TPC, and the TPC that sends to UE can be described as descending TPC.The TPC deletion that the storage mode of First Input First Output promptly will be stored when getting access to new TPC at first.
Certainly, the history value of TPC is carried out the variations statistics be not limited to up-to-date continuous several TPC that acquire are stored, also can obtain the history value of TPC the mode that the up-to-date TPC value of obtaining adds up.For example, when the value of TPC is " 1 " or " 0 ", two counters can be set respectively, the value of add up respectively up TPC and descending TPC is as the TPC history value.
In the present embodiment, the Node B specific implementation form that the SG of UE is distributed in adjustment according to the variations statistics also can have multiple, and for example, wherein a kind of specific implementation is:
Node B changes AG that distributes at least one UE and/or the RG that determines according to the scheduling factor according to the variations statistics.That is: Node B at first determines to distribute to AG and/or the RG of one or more UE according to other scheduling factors, and then Node B changes fixed AG and/or RG in conjunction with the variations statistics again, so that send to each UE.
Perhaps, the another kind of specific implementation of above-mentioned steps is:
Node B determines to distribute to AG and/or the RG of at least one UE according to variations statistics and at least one scheduling factor.That is: Node B as a newly-increased scheduling factor, takes the variations statistics into consideration determine to distribute to one or more UE AG and/or RG with original at least one scheduling factor, so that send to each UE.
Because flexibility and real-time that RG adjusts than AG, the technical scheme of various embodiments of the present invention are more suitable for adjusting SG by adjusting RG.
In concrete the application, the variations statistics is the variations trend that recognizes by the history value of adding up TPC, the scheduling strategy that Node B takes the scheduling factor of variations statistics and other situations of reflection into consideration can have a variety of, can come according to specific circumstances to determine.Present embodiment can obtain and consider to reflect in real time the parameter of variations when carrying out ascending resource scheduling, therefore can be so that UE be assigned with rational SG, for example distribute rational SG to take into account to guarantee resource not upload and do not increase and disturb two aspects, so can reduce the decoding mortality, reduce the uplink load that UE constantly retransmits, thereby improve the uplink throughput of UE reality.
Resource scheduling processing method second embodiment
Fig. 2 is the flow chart of resource scheduling processing method second embodiment of the present invention.Present embodiment can the foregoing description be the basis, adopt the mode of above-mentioned memory stores to obtain the history value of TPC, and in the present embodiment, the step of carrying out the variations statistics according to the history value of TPC specifically comprises:
Owing to may have a plurality of UE in the base station cell of Node B, then may be provided with a plurality of memories among this Node B, each UE correspondence is provided with two memories.Be that example illustrates above-mentioned steps with a pairing upward line storage of UE below:
Node B is in all TPC of the up memory stores of this UE, add up up-to-date get access to and continuous, have the number of the TPC of same commands value, concrete, according to the up-to-date order of obtaining the earliest that gets access to, the bid value of first and second TPC at first relatively, if identical then the counting and relatively the 3rd and first, the order comparison, different until bid value with the bid value of first TPC.When Node B judges up-to-date getting access to and number continuous, that have the TPC of same commands value when reaching first threshold value, illustrate that this UE has sent abundant TPC continuously, be Node B with down channel quality variation tendency between this UE be consistent, then Node B further discerns this same commands value.If recognition result is " an increase setting power ", the quality of then representing down channel so UE requires Node B to increase transmitting power all the time, determines correspondingly that the variations statistics is " quality decline " in continuous deterioration; Otherwise, if recognition result is " reducing setting power ", then represent the quality of down channel continuing to optimize, determine that correspondingly the variations statistics is " quality rising ".Node B can all add up TPC when needing definite AG and/or RG at every turn, if judge when not reaching first threshold value, illustrates that the variation tendency of channel quality fluctuates, and need not consider temporarily when distributing AG and/or RG.
Statistic processes for the TPC that stores in the following line storage is similar to the above process, can determine the variation tendency of uplink signal-channel quality accordingly.
The technical scheme of present embodiment can be determined variations trend by the bid value of adding up the up-to-date consecutive TPC that gets access to, determines that in conjunction with variations trend AG and/or RG can distribute rational SG for UE, thereby improves the uplink throughput of UE.

Below with the pairing line storage of going up of UE, and capacity of its storage TPC is ten and for example above-mentioned steps is described:
Node B is in ten TPC of the up memory stores of this UE, and statistics has the number of TPC of same commands value respectively, and relatively obtains to have the maximum of number of the TPC of same commands value.When judging maximum, NodeB reaches second threshold value, for example reach at 8 o'clock, illustrate that this UE has sent abundant TPC in setting-up time, the down channel quality variation between Node B and this UE roughly is tending towards certain orientation, and then Node B further discerns this same commands value.If recognition result is " an increase setting power ", the quality of then representing down channel determines correspondingly that in continuous deterioration the variations statistics is " quality decline "; Otherwise, if recognition result is " reducing setting power ", then represent the quality of down channel continuing to optimize, determine that correspondingly the variations statistics is " quality rising ".Node B can all add up TPC when needing definite RG at every turn, if judge when not reaching second threshold value, illustrates that the variation tendency of channel quality fluctuates, and need not consider temporarily when distributing AG and/or RG.
Statistic processes for the TPC that stores in the following line storage is similar to the above process, can determine the variation tendency of uplink signal-channel quality accordingly.
The technical scheme of present embodiment can be determined variations trend by the quantity of same commands value TPC in the statistics setting-up time, determine that in conjunction with variations trend AG and/or RG can distribute rational SG for UE, thereby improve the uplink throughput of UE, improve network utilisation efficient.
In above-mentioned the 3rd embodiment, also can be that the number of adding up the TPC with same commands value accounts for the number ratio of the TPC that has stored, and then judge whether the maximum of number ratio reaches the threshold value of setting.This technical scheme is to above-mentioned directly similar to the peaked judgement of number.
In the present invention above-mentioned second and the 3rd embodiment, be respectively the TPC in each memory to be added up, and obtain recognition result, can determine the variations statistics independently according to each recognition result.According to recognition result determine the variations statistics for " quality risings " or " quality decline " alternative mode can also for: will be at the recognition result combination of each memory acquisition, to determine that the variations statistics is " quality rising " or " quality decline ", promptly take each recognition result into consideration, can be that a UE is taken into consideration the recognition result that obtains at the statistics of the TPC in last line storage and the following line storage, perhaps can also be for as required, the recognition result of a plurality of UE correspondences is comprehensively considered, thus the variations statistics of integral body in the base station cell of definite this Node B.
