Description
Technical field
The invention relates to a kind of power adjustment apparatus and Modulating Power method thereof, the particularly method of the power adjustment apparatus in wireless system and Modulating Power thereof.
Background technology
In wireless telecommunication system, conveyer arrives place farthest in order to want to transmit as much as possible package, and the delivering power of transmission end normally transmits with maximum power.But in the time of the close together of receiving terminal and this transmission end, package is transmitted and can cause the waste of power in transmission end with this maximum power, simultaneously also likely because signal saturated (Saturation) or the signal of receiving that receiving terminal is received are limited (Clipping) and cannot correctly receive package.If therefore can correctly calculate the distance between transmission end and receiving terminal, can suitably change the delivering power of transmission end, make transmission end can reach with the power compared with little the same or even better transmit usefulness.
A kind of mode is to utilize the signal strength signal intensity of the received package in transmission end to judge the distance between transmission end and receiving terminal, but judge that according to signal strength signal intensity its distance likely can cause erroneous judgement, because the aerial refraction of signal, reflection or diffraction all can cause the decay (Fading) of signal, and cause the signal strength signal intensity of the received package in transmission end to decline or the rising of bit error rate (Bit Error Rate).For example, when the received signal strength signal intensity hour in transmission end, transmission end can judge distant between itself and receiving terminal, and causes transmission end to transmit package with larger delivering power, causes the waste of delivering power.Otherwise in the time that the received signal strength signal intensity in transmission end is large, transmission end can judge the close together between itself and receiving terminal, and causes transmission end to transmit package with less delivering power, causes receiving terminal cannot receive package.Therefore by signal strength signal intensity as the distance judging between transmission end and receiving terminal, be comparatively unsuitable in some cases.

Refer to Fig. 1 C, it is the schematic diagram that this case the first preferred embodiment receives response.If this power adjustment apparatus 10 is received the information of response ACK2 within the period of this response timeout ACK2 timeout, this processing unit 11 transmits follow-up package D_other according to response ACK2 information power ratio control adjustment unit 121 with power LV2.。
Refer to Fig. 1 D, its schematic diagram that is this case the second preferred embodiment package transmission status in this training period T.In Fig. 1 D, in this training period T, this first package D1 is transmitted at t1 time point with this power LV3, this Modulating Power device 10 receives response ACK1, these processing unit 11 power ratio control adjustment units 121 transmit package with another power LV2 that is less than power LV3, one second package D2 is transmitted at t2 time point with this power LV2, this Modulating Power device 10 receives response ACK2, these processing unit 11 power ratio control adjustment units 121 transmit package with another power LV1 that is less than power LV2, one the 3rd package D3 is transmitted at t3 time point with this power LV1, by that analogy, until cannot receive response ACK information.

Refer to Fig. 2 A, it is the flow chart that this case the 3rd preferred embodiment determines this delivering power P2.For example, this power adjustment apparatus 10 transmits 10 test packets in this training period T, and the power that to set and retransmit the power of zero degree be small-power, retransmit power is once middle power, retransmit twice is high-power, and the power retransmitting more than twice is maximum power.
Refer to Fig. 2 B, it is the schematic diagram that this case the 3rd preferred embodiment transmits successful package number.In Fig. 2 B, 10 test packets are as follows at the transmission status of this training period T: retransmit and transmit for the first time the successful package of retry0 for 0 time and count N_retry0=4, retransmit retry1 just successfully package count N_retry1=4, retransmit twice retry2 just successfully package count N_retry2=2, the package that exceedes twice re-transmission is counted N_other=0.Above-mentioned statistical value is multiplied by respectively weighted value W0, W1, W2, W_other and can obtains respectively corresponding weighted results R_retry0, R_retry1, R_retry2 and R_other, first suppose that at this weighted value W0, W1, W2, W_other are all 1, therefore its weighted results is respectively: R_retry0=N_retry0 × W0=4, R_retry1=N_retry1 × W1=4, R_retry2=N_retry2 × W2=2 and R_other=N_other × W_other=0.Represent that in the mode of ordered series of numbers above-mentioned weighted results can be write as R_retry[]=[4,4,2,0].At this, can know that the successful package of all transmission counts N_total=10, it is multiplied by an aggregative weighted value W_total=1 can obtain an aggregative weighted result R_total=10, with as one first threshold value.The package that the package that the package of 0 time is counted N_retry0=4 to processing unit 11, the package that retransmits 1 time is counted N_retry1=4 by retransmitting, retransmit 2 times counts N_retry2=2, exceed twice re-transmission is counted N_other=0, the successful package of all transmission is counted N_total=10, weighted results R_retry[]=[4,4,2,0] and aggregative weighted result R_total=10 be stored in 14 (for example buffers) in memory cell, to do computing and judgement.
It should be noted that multiple test packets can be identical package or different packages.It can be known parameter before transmitting that the successful package of all transmission is counted N_total, can be also to do cumulative obtaining according to the package number that success transmits each time.For example: if originally estimate to transmit 10 test packets at this training period T, but when the training period, T finished, only successfully transmitted 9 test packets at this, now the successful package of all transmission is counted N_total and calculated with 9.
Go back to Fig. 2 A, start now the explanation of step 20, in step 201, i=0 representative at the beginning retransmits 0 time, transmits for the first time, and Sum_Result represents successively accumulation result, sets its initial value Sum_Result=0 in step 201.Then enter step 202, by the i time accumulation result Sum_Result and an i weighted results R_retry[i] be added and obtain the i time accumulation result.Sum_Result。Judge when whether accumulation result Sum_Result is more than or equal to aggregative weighted result R_total (step 203), if, setting and retransmitting the power of i time is this delivering power P2, one of them that namely select this power LV1, this power LV2 and this power LV3 from these multiple power P 1 is as this delivering power P2 (step 204), for the transmission of follow-up package, then finish judgement (step 205).If not, when the i time accumulation result Sum_Result is less than aggregative weighted result, i is added to 1 (step 206), until accumulation result Sum_Result is more than or equal to aggregative weighted result R_total.
For example, in the time transmitting (i=0) for the first time, Sum_Result (initial value)+R_retry[0]=Sum_Result, be 0+4=4 < R_total=10, therefore enter step 206, i+1=1, then enter step 202, Sum_Result+R_retry[1]=Sum_Result, be 4+4=8 < R_total=10, therefore enter step 206, i+1=2, then enter step 202, Sum_Result[2]+R_retry[2]=Sum_Result[3], be 8+2=R_total1=10, therefore enter step 206, the power that setting re-transmission is twice is this delivering power P2.
Refer to Fig. 2 C, it is the normal distribution diagram that this case the 4th preferred embodiment transmits successful package number.In Fig. 2 C, area under a curve representative successful package number of all transmission in this training period T, it comprise retransmit 0 time just successfully package number, retransmit once successfully package number, retransmit twice successful package number and retransmit above successful package number twice, in normal distribution diagram, in this training period T, if can select suitable delivering power that 80% of all test packets can be transmitted successfully in the time transmitting for the first time, such method can select the mode that power is lower to transmit follow-up package adaptively.According to above-mentioned concept, this aggregative weighted value W_total in this this case the 3rd preferred embodiment is adjustable is made into 0.8, and the successful package of all transmission counts N_total=10 and is multiplied by aggregative weighted value W_total=0.8 and can obtains an aggregative weighted result R_total=8, with it as this first threshold value.
Because this first threshold value has reduced, so in this case the 3rd preferred embodiment, in the time retransmitting 1 time, Sum_Result+R_retry[1]=Sum_Result, be 4+4=8=R_total, then enter step 206, setting the power retransmitting is once this delivering power P2.
It is below this case the 5th preferred embodiment.In this case the 5th preferred embodiment, weighted value W0, W1, W2 and W_other configure in the mode of successively decreasing, for example W0=10, W1=7, W2=2 and W_other=0, therefore its weighted results is respectively: R_retry0=N_retry0 × W0=40, R_retry1=N_retry1 × W1=28, R_retry2=N_retry2 × W2=4 and R_other=N_other × W_other=0.Represent that in the mode of ordered series of numbers above-mentioned weighted results can be write as R_retry[]=[40,28,4,0].The successful package of all transmission is counted N_total=10 and is multiplied by aggregative weighted value W_total=6 and can obtains aggregative weighted result R_total=60, with it as this first threshold value.Therefore in the time of i=0, Sum_Result+R_retry[0]=Sum_Result, be 0+40=40 < 60=R_total, in the time of i=1, Sum_Result+R_retry[1]=Sum_Result, be 40+28=68 > 60=R_total, now meet the condition (step 203) that accumulation result Sum_Result is more than or equal to aggregative weighted result, therefore setting the power retransmitting is once this delivering power P2, and the benefit of this practice is to wish to transmit follow-up package with lower this delivering power P2 as far as possible.
Refer to Fig. 2 D, it is for determining the method for delivering power P2.In step 211, the multiple power P 1 of this power adjustment apparatus 10 use transmit multiple test packets.In step 212, within a period, this processing unit 11 is added up and in the plurality of test packets, is transmitted successful package number.In step 213, according to the number of retransmissions of these test packets, to determine the transmission of a delivering power for follow-up package.
Refer to Fig. 3, it is the flow chart that this case the 6th preferred embodiment determines this delivering power P2.In this embodiment, from big to small, therefore Rule of judgment is slightly different for delivering power.10 test packets are as follows at the transmission status of this training period T: retransmit the package that transmits for the first time successful retry0 for 0 time and count N_retry0=8, retransmit a successful package of retry1 and count N_retry1=2, exceed the package once retransmitting and count N_other=0.The package number of each re-transmission is multiplied by respectively weighted value W0=1, W1=1, W_other=1 and can obtains respectively corresponding weighted results R_retry0=8, R_retry1=2 and R_other=0, the successful package of all transmission is counted N_total=10, it is multiplied by aggregative weighted value W_total=1 can obtain aggregative weighted result R_total=10, with as this first threshold value.
In the 6th preferred embodiment, Sum_result represents successively accumulation result, and step 301 is supposed i=N=1 when beginning, Sum_result (initial value)=0.Step 302, Sum_result (initial value)+R_retry[1]=Sum_result, be 0+2=2 < 10=R_total, therefore after the judgement of step 303, can enter step 306, i-1=0, then enter step 302, Sum_result+R_retry[0]=2+8=10=R_total, after the judgement of step 303, can enter step 304, the power that selection re-transmission is 0 time is this delivering power P2, the power transmitting is for the first time this delivering power P2, transmits follow-up package D_other with this delivering power P2.Retransmitting after 1 time, the package of remaining sum 20% transmits successfully, reason may be that signal saturated (Saturation) or the signal of receiving that receiving terminal is received is limited (Clipping) and cannot correctly receives package, and therefore delivering power can correctly receive after reducing on the contrary.
