Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 1, be the schematic flow sheet of the first embodiment of the Poewr control method of many transmission channels of the present invention, described method comprises:
Step S11, measures the Block Error Rate of transmission channel, and adjusts the SIR of described transmission channel according to the Block Error Rate of described transmission channel, and according to the SIR after described transmission channel adjustment, determines a SIR.
Wherein, step S11 is to there being the Block Error Rate of the transmission channel of data to measure in current power control cycle, and one or more transmission channel can be had in current power control cycle to have data; When there being the transmission channel of data to have multiple, the Block Error Rate of step S11 to multiple transmission channel is measured, and then adjusts the SIR of described multiple transmission channel respectively, finally determines a SIR by the SIR after described multiple transmission channel adjustment.It should be noted that, according to Block Error Rate, the adjustment that adjustment can be a kind of expection is carried out to the SIR of transmission channel, instead of the adjustment of reality, its objective is to obtain a SIR.
Particularly, when step S11 records the Block Error Rate of transmission channel, the target Block Error Rate of the Block Error Rate recorded and transmission channel is compared, and adjust the SIR of transmission channel according to comparative result.Such as transmission channel A, suppose that the target Block Error Rate netting the transmission channel A that side issues is 10%; If in current power control cycle, the Block Error Rate recording transmission channel A is 8%, so due to 8% < 10%, therefore the SIR of transmission channel A reduces an adjustment step-length as the target SIR of the output of open sea wharf in a upper power control period; If in current power control cycle, the Block Error Rate recording transmission channel A is 12%, so due to 12% > 10%, therefore the SIR of transmission channel A increases an adjustment step-length as the target SIR of the output of open sea wharf in a upper power control period.It should be noted that, adjustment step-length can according to transmission channel A regulate the speed and precision pre-set; The adjustment step-length of different transmission channel can be identical or different; For same transmission channel, can according to the concrete magnitude relationship of Block Error Rate and target Block Error Rate, as the basis of the target SIR of the output of open sea wharf increasing or reducing multiple adjustment step-length in upper once power control period.
Further, after having the SIR of multiple transmission channel to be adjusted, from the SIR after adjustment, select maximum as a SIR, to ensure the transmission quality of each transmission channel in multiple transmission channel.
Step S12, obtains the SIR protection value of the transmission channel being provided with SIR protection, and select maximum, as the target SIR of the output of open sea wharf from the SIR protection value and a described SIR of described acquisition.
Wherein, in advance SIR protection can be set to one or more transmission channel.If there is multiple transmission channel to be provided with SIR protection, obtains the SIR protection value that each is provided with the transmission channel of SIR protection so respectively, and select maximum as the target SIR of the output of open sea wharf from the multiple SIR protection value obtained and a SIR.Such as hypothesis has transmission channel A, B and C, transmission channel A and B has data in current power control cycle, transmission channel C does not have data in current power control cycle but transmission channel C is provided with SIR protection, so from the SIR protection value of the SIR determined by transmission channel A and B and transmission channel C, select the target SIR that maximum exports as open sea wharf; Due to transmission channel C is provided with SIR protection, although therefore in current power control cycle transmission channel C there is no data, if transmission channel C has data in upper once power control period, then can ensure the transmission quality of transmission channel C.
Step S13, measures the SIR of physical channel, and according to the magnitude relationship of the SIR recorded and target SIR, generates the transmitting power control TPC command of the output as inner-loop power control, and issue network side by described TPC command.
Particularly, when the SIR recorded is higher than target SIR, then generate the TPC command that Controling network side increases transmitting power; When the SIR recorded is lower than target SIR, then generate the TPC command that Controling network side reduces transmitting power.Because target SIR is determined jointly by a SIR and the SIR protection value being provided with the transmission channel that SIR protects; therefore step S13 by the TPC command of generation is issued net side after; the transmitting power had in current power control cycle needed for the transmission channel of data can either be ensured making net side in subsequent power control cycle, the transmitting power needed for transmission channel being provided with SIR protection can be ensured again.
The embodiment of the present invention is owing to can arrange SIR protection to transmission channel, such as: SIR protection is arranged for important transmission channel, and the target SIR of the output as open sea wharf is jointly determined according to the SIR protection value of transmission channel and the SIR that determined by the Block Error Rate of each transmission channel measured that are provided with SIR protection, thus enable the TPC command issuing network side finally enable the transmitting power of net side ensure the transmission quality of the transmission channel being provided with SIR protection, no matter and whether the transmission channel being provided with SIR has data in current power control cycle.
Please refer to Fig. 2, be the schematic flow sheet of the second embodiment of the Poewr control method of many transmission channels of the present invention, described method comprises:
Step S21, measures the Block Error Rate of transmission channel, and adjusts the SIR of described transmission channel according to the Block Error Rate of described transmission channel, and according to the SIR of described transmission channel, determines a SIR.
This step is identical with the step S11 of Fig. 1, is not repeated herein.
Step S22, for the transmission channel being provided with SIR protection, according to the described data cases being provided with the transmission channel of SIR protection, is provided with the SIR protection value of the transmission channel of SIR protection described in adjustment.
Particularly, the transmission channel being provided with SIR protection in step S22 can be one or more.When the transmission channel being provided with SIR protection has multiple; each is provided with to the transmission channel of SIR protection; in current power control cycle, whether can have data according to it and when there being data, whether have the situations such as error code, dynamically adjust its SIR protection value.Such as: suppose that transmission channel A is the transmission channel being provided with SIR protection; if transmission channel A has data and has error code in current power control cycle, so the SIR protection value of transmission channel A can be adjusted to (current SIR protection is worth+adjusts step-length).
Step S23, obtains the SIR protection value of the transmission channel being provided with SIR protection, and selects maximum, as the target SIR of the output of open sea wharf from the SIR protection value obtained and a SIR.
It should be noted that, the SIR protection value obtained in this step refers to the SIR protection value being provided with the transmission channel of SIR protection obtained after step S22 adjustment, and in this step, remainder is identical with step S12 in Fig. 1, is not repeated herein herein.
Step S24, measures the SIR of physical channel, and according to the magnitude relationship of the SIR recorded and target SIR, generates the transmitting power control TPC command of the output as inner-loop power control, and issue network side by described TPC command.
This step is identical with step S13 in Fig. 1, is not repeated herein.
The present embodiment is for the transmission channel being provided with SIR protection; according to its data cases in current power control cycle; adjust its SIR protection value; thus SIR protection value can be adjusted to ideal, suitable degree; avoid the excessive transmitting power of net side that causes of the SIR protection value of the transmission channel owing to being provided with SIR protection higher; or because the SIR protection value of the transmission channel being provided with SIR protection is too small, and the effect of protection transmission channel can not be played.Below in conjunction with Fig. 3 and Fig. 4, more specific description is carried out to above-mentioned step S22.
Please refer to Fig. 3, be the schematic flow sheet about first embodiment of step S22 in Fig. 2, described step S22 comprises:
Step S31, for the transmission channel being provided with SIR protection, when the transmission channel of the described SIR of being provided with protection have data and without error code time, whether the SIR protection value being provided with the transmission channel of SIR protection described in judgement is greater than a SIR.
Wherein, a SIR refers to the SIR that in Fig. 2, step S21 determines.Particularly; to be provided with the transmission channel A of SIR protection, if in current power control cycle, transmission channel A has data and without error code, so as SIR protection value < the one SIR of transmission channel A; then perform step S32, otherwise perform step S33.
Step S32, detects the difference of a SIR and described SIR protection value.
Particularly; when the predetermined threshold value of (a SIR-SIR protection value) > being detected; perform step S33; when the predetermined protection value of (a SIR-SIR protection value) < being detected; perform step S34, it should be noted that, predetermined threshold value can pre-set herein; to ensure that SIR protection value can not too lower than a SIR, namely for controlling the degree of SIR protection value lower than a SIR downwards.
Step S33, by described SIR protection value reduction one adjustment step-length, process ends.
Particularly; for transmission channel A; as SIR protection value > the one SIR of transmission channel A; or SIR protection value < the one SIR of transmission channel A but (a SIR-SIR protection value) > predetermined threshold value time, the SIR protection value of transmission channel A is adjusted to (current SIR protection is worth-adjusts step-length).
Step S34, is set to a SIR by described SIR protection value and deducts predetermined threshold value, process ends.
Particularly; for transmission channel A; the SIR protection value of transmission channel A is adjusted to (a SIR-threshold value); this be in transmission channel A in current power control cycle have data but without error code time; when SIR protection value is less than a SIR and the degree that SIR protection value is less than a SIR exceedes threshold value; then SIR protection value is adjusted to (a SIR-threshold value), falls too low to avoid SIR protection value.
The present embodiment transmission channel have data and without error code time, the SIR protection value of transmission channel is adjusted, avoids SIR protection value to establish get Tai Gao, and can not ensure transmission quality prerequisite under, farthest reduce net side emissivity.

Step S41; for the transmission channel being provided with SIR protection; when the described transmission channel being provided with SIR protection countless according to time, judge whether to start timer, described timer does not have the time of data continuously for the transmission channel being provided with SIR protection described in recording.
Particularly, if be not activated timer, then perform step S45: start timer, there is no the time of data with the transmission channel starting to be provided with described in record SIR protection continuously; If start timer, then perform step S42.It should be noted that, because timer is the time not having data for recording the transmission channel being provided with SIR protection continuously, therefore in the timing course of timer, when the transmission channel being provided with SIR protection has data, timer being reset.Also it should be noted that, if the transmission channel being provided with SIR protection has multiple, then the timer that the different transmission channels being provided with SIR protection is corresponding is different.
Step S42, judges the time of timer record is provided with the protection duration of transmission channel of SIR protection described in whether having reached.
Particularly, suppose that the protection duration of transmission channel A is T, the transmission channel A of timer record does not have the time of data to be t continuously, so as T < t, forwards step S43 to, as T > t, performs step S44.
Step S43, is set to a SIR by the SIR protection value of the transmission channel of the described SIR of being provided with protection and deducts predetermined threshold value.Herein, for transmission channel A, the SIR protection value of transmission channel A is set to (a SIR-threshold value).
Step S45, is provided with the SIR protection value of the transmission channel of SIR protection described in maintenance, to continue to carry out SIR protection to the transmission channel of the described SIR of being provided with protection.
The present embodiment, each is provided with to the transmission channel of SIR protection, when it does not have the time of data to exceed protection duration continuously, then its SIR protection value is set to the difference of a SIR and predetermined threshold value, to supspend the protection to this transmission channel, thus to avoid carrying out data frequency for some too low or just do not have the unnecessary protection of the transmission channel of data at all; It should be noted that the SIR protection value of transmission channel is set to a SIR deducts a kind of execution mode that predetermined threshold value just supspends the protection to transmission channel herein, the present embodiment does not limit concrete implementation.
