Description

A kind of method, Apparatus and system of power control
Technical field
The present invention relates to the communications field, particularly a kind of method, Apparatus and system of power control.
Background technology
Power control is the basic conception in the cellular mobile communication.Because code division multiple access (Code DivisionMultiple Access, CDMA) system is an interference-limited system, so that it is very responsive to the variation of the transmitted power of signal and the characteristic of channel.Therefore, in order can effectively to control inter-user interference, to improve the utilance of power, thereby improve user capacity and the speech quality of whole system, and then more effectively utilize Radio Resource, power control just becomes indispensable important means.
Whether power control participates in being divided into again open Loop Power control and close-loop power control two large classes simultaneously by travelling carriage and base station.Closed-loop power control refers to the process that feedback information that transmitting terminal is sent here according to receiving terminal is controlled transmitting power; And open loop power control does not need the feedback of receiving terminal, and the information that transmitting terminal measures according to self is controlled transmitting power.Close-loop power control can be divided into again the control of inner-loop power control and exterior ring power.Inner-loop power control mainly compares by received signal to noise ratio and target signal to noise ratio, determines power adjustment stepping.Exterior ring power control is upgraded target signal to noise ratio according to QoS or Block Error Rate (Block Error Rate, the BLER) requirement of business.Because under different wireless channel environments, the target signal to noise ratio value that satisfies the qos requirement needs is different, and because channel circumstance is constantly to change, is difficult to obtain the target signal to noise ratio value of a universality, therefore adds exterior ring power control.In the outer shroud control, receiving terminal detects the error probability (BLER) of code block, and upgrades thus the target signal to noise ratio value, if error probability is lower than qos requirement, controller reduces the target signal to noise ratio value so; Otherwise, then increase the target signal to noise ratio value.
At synchronous code division multiple access of time-division (Time Division-Synchronous Code Division MultipleAccess, TD-SCDMA) in the system, strengthening special uplink channel absolute grant channel (E-DCHAbsolute Grant Channel, E-AGCH) and the shared control channel of high speed descending sharing channel (Sharedcontrol channel for HS-DSCH, HS-SCCH) in the channel transmission information, in order to save the bit carrying, in the information bit that is contained in E-AGCH/HS-SCCH of UE-ID implicit expression, namely by carrying out xor operation with cyclic check code (CRC), jointly embody the function of CRC check.Cause that the reason of CRC check mistake has two classes this moment, the one, and this information does not belong to this travelling carriage (User Equipment, UE), and the 2nd, transfer of data mistake piece; Therefore, the method by CRC check statistics BLER is not suitable for above-mentioned two class channels.So in the channel transmission information of HS-SCCH and E-AGCH, introduced E-AGCH cyclic sequence number (E-AGCH Cyclic Sequence Number, ECSN) and HS-SCCH cyclic sequence number (HS-SCCH Cyclic Sequence Number, HCSN), wherein ECSN and HCSN respectively account for 3 bits.Transmitting terminal is according to the delivery time of E-AGCH/HS-SCCH, for it arranges cyclic sequence number, receiving terminal judges whether to have lost the E-AGCH/HS-SCCH channel according to the continuity of the ECSN/HSCN that receives, namely when CRC check is correct, read this ECSN/HCSN, by comparing with previous ECSN/HCSN, judge whether that circulation continuously, if discontinuous, according to the difference of numbering, the channel number that can add up the E-AGCH/HS-SCCH that loses, and then calculate shared channel in a period of time lose piece probability (Block Error Rate, BLER), thereby upgrade the Offered target signal to noise ratio, reach the purpose of exterior ring power control.As seen, in current standard, because the channel format of E-AGCH/HS-SCCH channel, ECSN/HCSN becomes the only resource of its statistical channel BLER.
Yet, under the prior art, supporting the transmitting terminal of single-carrier technology, can only send and receive information at a carrier wave.Therefore, the Traffic Channel of E-AGCH/HS-SCCH channel and its scheduling is carried on the same carrier wave, and at any one Transmission Time Interval (Transmission Time Interval, TTI) in, receiving terminal only can be accepted the scheduling of a shared channel, therefore, the setting of single carrier ECSN/HCSN, just for the E-AGCH/HS-SCCH channel on the carrier wave, according to delivery time, to its circulation numbering of progressively increasing.
And after introducing the multi-carrier HSDPA technology, receiving terminal has had the ability that receives simultaneously a plurality of carrier waves, control all carrier wave high speed downlink packet access (High Speed Downlink Shared Channel, HS-PDSCH) HS-SCCH channel can all be configured on the carrier wave, and the shared channel of namely dispatching a certain carrier wave can not be carried on this carrier wave.And the base station can be dispatched for a plurality of carrier waves in same TTI.In the multi-carrier HSUPA stage, terminal can send and receive information at a plurality of carrier waves.The E-AGCH channel distribution of each carrier wave is on the E-PUCH carrier wave of this channel control (the more mode), and the base station can be dispatched for a plurality of carrier waves at same TTI.The situation of this and single-carrier system is very different, therefore, and the ECSN in the situation of single carrier that provides under the prior art and the method for numbering serial of HCSN and the method for carrying out exterior ring power control according to ECSN and HCSN, obviously and be not suitable for multicarrier system.
In view of this, need to redesign the method for numbering serial of shared channel and the power control mode that adopts according to different method for numbering serial for multicarrier system.

Embodiment
At present, in the mobile communication system that adopts single-carrier technology, transmitting terminal often adopts the method for adding the cyclic sequence numbering in the transmission information of shared channel, and the auxiliary reception end carries out power control.Employing along with multi-transceiver technology, multi carrier wave high-speed downlink grouping access (Multi-carrier High Speed DownlinkPacket Access, MC-HSDPA) and multi-carrier high-speed upstream packet access access waies such as (Multi-carrier HighSpeed Downlink Packet Access, MC-HSUPA) be introduced in the mobile communication system.Existing numbering cycle mode for shared channel under the single carrier can't well reach the purpose that the auxiliary reception end carries out power control, therefore in the embodiment of the invention, for multicarrier system, proposed the employed numbering cycle method for shared channel of a kind of new transmitting terminal, be used for the auxiliary reception end and finish power control.
Wherein, so-called shared channel can be E-AGCH or HS-SCCH, it can also be the shared channel of other kinds, the common feature of this kind shared channel is being contained in cyclic check code (CRC) check information of UE-ID implicit expression, therefore, can only lose piece probability (BLER) by the mode auxiliary reception end statistics of shared channel being carried out numbering cycle, thereby reach the purpose of power control.Transmitting terminal can be the base station, it also can be terminal, accordingly, receiving terminal can be terminal, it also can be the base station, in order to make transmitting terminal consistent to the understanding of numbering with receiving terminal, both sides can adopt the make an appointment numbering cycle mode of shared channel of high-level signaling, physics signaling or consensus standard.
Below in conjunction with accompanying drawing the preferred embodiment of the present invention is elaborated.
In the embodiment of the invention, it is for receiving terminal being carried out power control indication that transmitting terminal is numbered each shared channel that carries on the multicarrier, consult shown in Figure 1, transmitting terminal is numbered based on the shared channel to a plurality of carriers carry, and the detailed process of the power control indication of the receiving end that achieves a butt joint is as follows:
Step 100: transmitting terminal determines to transmit a plurality of carrier waves that data need be used.
Step 110: transmitting terminal is take TTI as unit, and the shared channel that carries separately for a plurality of carrier waves carries out numbering cycle.
Step 120: transmitting terminal utilizes above-mentioned a plurality of carrier wave that the numbering of each shared channel is sent to receiving terminal, and the indication receiving terminal is carried out corresponding power control according to the continuity of the numbering of each shared channel.
During execution in step 120, transmitting terminal transmits data by each shared channel of a plurality of carriers carry to receiving terminal, and since the numbering of each shared channel be carried in the channel transmission information of its transmission as the part of channel format, therefore, when receiving terminal receives the data that transmitting terminal transmits by each shared channel, also received the numbering of each shared channel.
In the above-described embodiments, transmitting terminal is when execution in step 110, including but not limited to following A and B dual mode:
Mode A, take TTI as unit, carry out the independent loops numbering for the shared channel of each carriers carry respectively; Namely in a plurality of carrier waves, TTI of every arrival, the shared channel that respectively a plurality of carrier waves is carried separately carries out numbering cycle independently.
During implementation A, be divided into again three kinds of implementations of following a1, a2 and a3:
A1, in same carrier wave, will adopt same numbering at many shared channels of same TTI.
For example, consult shown in Figure 2ly, in the TTIt+1 of carrier wave i, the shared channel of the shared channel of control carrier wave i+1, control carrier wave i+2 and the shared channel of control carrier wave i+3 all are numbered 1.
The numbering of other carrier waves is identical with carrier wave i, does not repeat them here.
The maximum of the numbering of each shared channel is L (L for default natural number), be filled to shared channel channel transmission information (as, format) in, all adopt same procedure to carry the numbering of shared channel in following examples, also repeat no more.
A2, in same carrier wave, will adopt at many shared channels of same TTI different numberings.
For example, consult shown in Figure 3ly, in the TTIt+1 of carrier wave i, the shared channel of control carrier wave i+1 is numbered 1, and the shared channel of control carrier wave i+2 is numbered 2, and the shared channel of control carrier wave i+3 is numbered 3.
The numbering of other carrier waves is identical with carrier wave i, also repeats no more at this.
On the other hand, when the mode of employing a2 is numbered, for many shared channels by same carriers carry at same TTI, carry out numbering cycle according to the channel code order from low to high that each shared channel adopts, the frequency order from low to high of the carrier wave of perhaps, controlling according to each shared channel is carried out numbering cycle.
A3, in same carrier wave, in different TTI but the shared channel of controlling same carrier wave carries out numbering cycle.
For example, consult shown in Figure 4ly, the shared channel of control carrier wave i is numbered respectively 0,1,2 in TTI t, TTI t+1 and TTI t+2, and the shared channel of control carrier wave i+1 is numbered respectively 0 and 1 in TTI t+1 and TTI t+2, its numbering is independent of one another, does not interfere with each other; And because the shared channel of a certain carrier wave of control only allows to occur once, therefore the numbering conflict can not appear in a TTI.
Mode B, take TTI as unit, the shared channel that carries separately for a plurality of carrier waves carries out the combined cycle numbering; Namely between a plurality of carrier waves, TTI of every arrival, the shared channel that a plurality of carrier waves are carried separately carries out numbering cycle uniformly.
During implementation B, be divided into again three kinds of implementations of following b1, b2 and b3:
B1, between a plurality of carrier waves, will adopt same numbering at many shared channels of same TTI.For example, consult shown in Figure 5ly, in the TTI of carrier wave i t+1, the shared channel of the shared channel of control carrier wave i, control carrier wave i+1 all is numbered 1, and simultaneously, in the TTI of carrier wave i+1 t+1, the shared channel of control carrier wave i+2 also is numbered 1.When shared channel is numbered, does not distinguish shared channel and specifically control that carrier wave.
The numbering of other carrier waves is identical with carrier wave i, does not repeat them here.
The maximum of the numbering of each shared channel is L (L for default natural number), be filled to shared channel channel transmission information (as, format) in, all adopt same procedure to carry the numbering of shared channel in following examples, also repeat no more.
B2, between a plurality of carrier waves, will adopt at many shared channels of same TTI different numberings;
For example, consult shown in Figure 6ly, in the TTI of carrier wave i t+1, the shared channel of control carrier wave i is numbered 1, the shared channel of control carrier wave i+1 is numbered 2, and simultaneously, in the TTI of carrier wave i+1 t+1, the shared channel of control carrier wave i+2 is numbered 3.When shared channel is numbered, does not distinguish shared channel and specifically control that carrier wave.
On the other hand, when the mode of employing b2 is numbered, for many shared channels by many carrier wave carryings at same TTI, carry out numbering cycle according to the channel code order from low to high that each shared channel adopts, the frequency order from low to high of the carrier wave of perhaps, controlling according to each shared channel is carried out numbering cycle.
B3, between a plurality of carrier waves, in different TTI but the shared channel of controlling same carrier wave carries out numbering cycle.
For example, consult shown in Figure 7ly, the shared channel of control carrier wave i is numbered 0 in the TTI of carrier wave i t, and the shared channel of control carrier wave i is numbered 1 in the TTI of carrier wave i+1 t+1, and the shared channel of control carrier wave i is numbered 2 in the TTI of carrier frequency i t+2; In like manner, the shared channel of control carrier wave i+1 is numbered 0 in the TTI of carrier wave i t+1, and the shared channel of control carrier wave i+1 is numbered 1 in the TTI of carrier frequency i+1 t+2.Its numbering is independent of one another, does not interfere with each other; And because the shared channel of a certain carrier wave of control only allows to occur once, therefore the numbering conflict can not appear in a TTI
Based on above-described embodiment, to consult shown in Figure 8ly, in the embodiment of the invention, the detailed process that receiving terminal carries out power control according to the indication of transmitting terminal is as follows:
Step 800: the receiving terminal receiving end/sending end adopts the numbering of each shared channel of step 100-step 120 transmission.
In the practical application, when receiving terminal receives the data that transmitting terminal transmits by each shared channel, to carry out cyclic check code (CRC) verification to these data first, when confirming that data are correct, the numbering that reads out again shared channel is carried out the continuity judgement, all adopt this kind mode in following examples, will repeat no more.
Step 810: receiving terminal is take TTI as unit, loses the piece probability according to what the continuity of the numbering of each shared channel of a plurality of carriers carry was added up these a plurality of carrier waves.
Step 820: receiving terminal is lost the piece probability based on a plurality of carrier waves of statistics, resets the target signal to noise ratio of above-mentioned a plurality of carrier waves.
In above-described embodiment, when execution in step 810, including but not limited to following X, Y, three kinds of implementations of Z:
If the shared channel that mode X transmitting terminal carries for above-mentioned a plurality of carrier waves respectively separately take TTI as unit carries out the independent loops numbering, then receiving terminal is lost the piece probability statistics independently for above-mentioned a plurality of carrier waves respectively.
When implementation X, be divided into again three kinds of implementations of following x1, x2 and x3:
If the x1 transmitting terminal is in same carrier wave, to adopt same numbering at many shared channels of same TTI, then receiving terminal is respectively for above-mentioned a plurality of carrier waves, judges in the numbering of the shared channel that current TTI receives, satisfy successional numbering number whether reach set threshold value (as, article 1), if, then determine not lose channel, otherwise, determine to lose channel, and lose the piece probability based on what judged result was added up respectively above-mentioned a plurality of carrier waves.
After receiving terminal is lost the piece probability statistics for above-mentioned a plurality of carrier waves respectively, also need according to above-mentioned a plurality of carrier waves separately lose the piece probability, reset corresponding target signal to noise ratio for above-mentioned a plurality of carrier waves respectively.
For example: the shared channel of the upper carrying of carrier wave i is HS-SCCH, and transmitting terminal adopts the a1 mode to be numbered, so, after receiving terminal receives the data of transmitting terminal transmission, carry out first the CRC check, after verification is passed through, read the HCSN of each HS-SCCH, the HCSN that supposes the HS-SCCH 1 that receiving terminal receives in TTI t is that the HCSN of 0, HS-SCCH 2 is 0, then:
Be that the HCSN of the HS-SCCH in the HCSN of 1, two HS-SCCH and the TTI t all keeps then determining not lose HS-SCCH in TTI t+1 continuously if the HCSN of the HS-SCCH 1 that receiving terminal receives in TTI t+2 is the HCSN of 1, HS-SCCH 2;
Be that the HCSN of the HS-SCCH in the HCSN of 2, two HS-SCCH and the TTI t all keeps continuously if the HCSN of the HS-SCCH 1 that receiving terminal receives in TTI t+2 is the HCSN of 2, HS-SCCH2, then determine in TTI t+1, to lose HS-SCCH;
So, on the carrier wave i, do not receive HCSN and be 1 HS-SCCH channel, received HCSN and be 0,2 HS-SCCH channel, namely correctly receiving the piece number is 2, and the piece number of losing is 1, and by the lasting statistics of a period of time, what calculate carrier frequency i loses the piece probability.By emulation, can obtain under the different channels environment, the corresponding relation curve of BLER and signal to noise ratio (SIR) provides the HS-SCCH channel under the different channels environment in the table 1, be 0.01 o'clock at BLER, required signal to noise ratio.Suppose, the BLER that obtains of statistics is 0.015, prove that channel circumstance has at this moment worsened, and it has been 0.01 requirement that former target signal to noise ratio can not satisfy BLER, need the target signal to noise ratio of carrier wave i is re-set as-8.61dB by-9.40dB, thereby finished the exterior ring power control of HS-SCCH channel.Wherein, the corresponding relation between BLER and the SIR depends on concrete algorithm realization, and table 1 just provides an example.
Table 1
Above-described embodiment is equally applicable to the E-AGCH channel in the multicarrier system, and the E-PUCH of E-AGCH and its scheduling is common carrier generally, for example, the shared channel of scheduling carrier wave i all is carried on the carrier frequency i, for this situation, above-described embodiment is applicable equally, does not repeat them here.
If the x2 transmitting terminal is in same carrier wave, to adopt at many shared channels of same TTI different numberings, then receiving terminal is respectively for above-mentioned a plurality of carrier waves, whether judgement all satisfies continuity in the numbering of all shared channels that current TTI receives, if, then determine not lose shared channel, otherwise, determine to lose shared channel, and lose the piece probability based on what judged result was added up respectively above-mentioned a plurality of carrier waves.
After receiving terminal is lost the piece probability statistics for above-mentioned a plurality of carrier waves respectively, also need according to above-mentioned a plurality of carrier waves separately lose the piece probability, reset corresponding target signal to noise ratio for above-mentioned a plurality of carrier waves respectively.
For example: the shared channel of the upper carrying of carrier wave i is HS-SCCH, and transmitting terminal adopts the a2 mode to be numbered, so, after receiving terminal receives the data of transmitting terminal transmission, carry out first the CRC check, after verification is passed through, read the HCSN of each HS-SCCH, the HCSN that supposes the HS-SCCH 1 that receiving terminal receives in TTI t is that the HCSN of 0, HS-SCCH 2 is 1, then:
Be that the HCSN of the HS-SCCH in the HCSN of 3, two HS-SCCH and the TTI all keeps then determining not lose HS-SCCH in TTI t+1 continuously if the HCSN of the HS-SCCH 1 that receiving terminal receives in TTI t+2 is the HCSN of 2, HS-SCCH 2;
Be that the HCSN of the HS-SCCH in the HCSN of 4, HS-SCCH and the TTI t does not keep continuously if the HCSN of the HS-SCCH 1 that receiving terminal receives in TTI t+2 is the HCSN of 3, HS-SCCH2, then determine in TTI t+1, to lose HS-SCCH;
So, on the carrier wave i, do not receive HCSN and be 2 HS-SCCH channel, received HCSN and be 0,1,3,4 HS-SCCH channel, namely correctly receiving the piece number is 4, and the piece number of losing is 1, and by the lasting statistics of a period of time, what calculate carrier frequency i loses the piece probability.By emulation, can obtain under the different channels environment, the corresponding relation curve of BLER and SIR provides the HS-SCCH channel under the different channels environment in the table 1, be 0.01 o'clock at BLER, required signal to noise ratio.Suppose, the BLER that obtains of statistics is 0.015, prove that channel circumstance has at this moment worsened, and it is 0.01 requirement that former target signal to noise ratio can not satisfy BLER, need the target signal to noise ratio of carrier wave i is re-set as-8.61dB by-9.40dB, thereby finished the exterior ring power control of HS-SCCH channel.
Above-described embodiment is equally applicable to the E-AGCH channel in the multicarrier system, and the E-PUCH of E-AGCH and its scheduling is common carrier generally, for example, the shared channel of scheduling carrier wave i all is carried on the carrier frequency i, for this situation, above-described embodiment is applicable equally, does not repeat them here.
If the x3 transmitting terminal is in same carrier wave, for in different TTI but the shared channel of controlling same carrier wave carries out numbering cycle, then receiving terminal is respectively for above-mentioned a plurality of carrier waves, whether judgement satisfies continuity in the numbering of the shared channel of a certain carrier wave of control of current TTI reception, if, then determine not lose shared channel, otherwise, determine to lose shared channel, and lose the piece probability based on what judged result was added up respectively above-mentioned a plurality of carrier waves.
After receiving terminal is lost the piece probability statistics for above-mentioned a plurality of carrier waves respectively, also need according to above-mentioned a plurality of carrier waves separately lose the piece probability, reset corresponding target signal to noise ratio for above-mentioned a plurality of carrier waves respectively.
For example: carrying the shared channel HS-SCCH1 that controls carrier wave i on the carrier wave i, the shared channel HS-SCCH 2 of control carrier wave i+1, and transmitting terminal adopts the a3 mode to be numbered, so, and after receiving terminal receives the data of transmitting terminal transmission, carry out first the CRC check, after verification is passed through, read the HCSN of each HS-SCCH, the HCSN that supposes the HS-SCCH 1 that receiving terminal receives in TTI t is 0, the HCSN of HS-SCCH2 is 1, then:
Be that the HCSN of the HS-SCCH in the HCSN of 2, two HS-SCCH and the TTIt all keeps then determining not lose HS-SCCH in TTI t+1 continuously if the HCSN of the HS-SCCH 1 that receiving terminal receives in TTI t+2 is the HCSN of 1, HS-SCCH 2;
Be that the HCSN of the HS-SCCH in the HCSN of 3, HS-SCCH and the TTI t does not keep continuously if the HCSN of the HS-SCCH 1 that receiving terminal receives in TTI t+2 is the HCSN of 2, HS-SCCH2, then determine in TTI t+1, to lose HS-SCCH;
So, for the shared channel of control carrier wave i, do not receive HCSN and be 1 HS-SCCH channel, received HCSN and be 0,2 HS-SCCH channel, namely correctly receiving the piece number is 2, and the piece number of losing is 1; The shared channel of control carrier wave i+1 is not received to be numbered 2 HS-SCCH channel, has received to be numbered 1,3 HS-SCCH channel; Total piece number of losing is 1+1=2, and total piece number that receives is 2+2=4.By the lasting statistics of a period of time, what calculate carrier frequency i loses the piece probability.By emulation, can obtain under the different channels environment, the corresponding relation curve of BLER and SIR provides the HS-SCCH channel under the different channels environment in the table 1, be 0.01 o'clock at BLER, required signal to noise ratio.Suppose, the BLER that obtains of statistics is 0.015, prove that channel circumstance has at this moment worsened, and it is 0.01 requirement that former target signal to noise ratio can not satisfy BLER, need the target signal to noise ratio of carrier wave i is re-set as-8.61dB by-9.40dB, thereby finished the exterior ring power control of HS-SCCH channel.
Above-described embodiment is equally applicable to the E-AGCH channel in the multicarrier system, and the E-PUCH of E-AGCH and its scheduling is common carrier generally, for example, the shared channel of scheduling carrier wave i all is carried on the carrier frequency i, for this situation, above-described embodiment is applicable equally, does not repeat them here.
If mode Y transmitting terminal is take TTI as unit, the shared channel that carries separately for above-mentioned a plurality of carrier waves respectively carries out the independent loops numbering, and then receiving terminal is lost the piece probability statistics for above-mentioned a plurality of carrier wave unifications.
When implementation Y, be divided into again three kinds of implementations of following y1, y2 and y3:
If the y1 transmitting terminal is in same carrier wave, to adopt same numbering at many shared channels of same TTI, then receiving terminal is respectively for above-mentioned a plurality of carrier waves, judgement is satisfied successional numbering number and whether is reached the setting threshold value in the numbering of the shared channel that current TTI receives, if, then determine not lose channel, otherwise, determine to lose channel, and lose the piece probability based on the above-mentioned a plurality of carrier waves of the unified statistics of judged result.
After above-mentioned receiving terminal is lost the piece probability statistics for above-mentioned a plurality of carrier wave unifications, also need to lose the piece probability according to what obtain, reset corresponding target signal to noise ratio for above-mentioned a plurality of carrier wave unifications.
For example: the control carrier wave i shared channel of the upper carrying of carrier wave i is HS-SCCH1, the shared channel of control carrier wave i+2 is HS-SCCH2, the shared channel of the control carrier wave i+1 of the upper carrying of carrier wave i+1 is HS-SCCH3, and transmitting terminal adopts the a1 mode to be numbered, so, after receiving terminal receives the data of transmitting terminal transmission, carry out first the CRC check, after verification is passed through, read the HCSN of each HS-SCCH, the HCSN that supposes the HS-SCCH 1 that receiving terminal receives in TTI t is that the HCSN of 0, HS-SCCH 2 is 0, the HCSN of HS-SCCH3 is 1, then:
Be that the HCSN of the HS-SCCH in the HCSN of 1, two HS-SCCH and the TTI t all keeps continuously if the HCSN of the HS-SCCH 1 that receiving terminal receives in TTI t+2 is the HCSN of 1, HS-SCCH 2, then definite carrier wave i does not lose HS-SCCH in TTI t+1; Keep continuously if the HCSN of the HS-SCCH 3 that receiving terminal receives in TTI t+2 is the HCSN of 2, HS-SCCH and the HCSN of the HS-SCCH in the TTI t, determine that then carrier wave i+1 does not lose HS-SCCH in TTI t+1;
Be that the HCSN of the HS-SCCH in the HCSN of 2, two HS-SCCH and the TTI t all keeps continuously if the HCSN of the HS-SCCH 1 that receiving terminal receives in TTI t+2 is the HCSN of 2, HS-SCCH2, determine that then carrier wave i loses HS-SCCH in TTI t+1; Do not keep continuously if the HCSN of the HS-SCCH 3 that receiving terminal receives in TTI t+2 is the HCSN of 3, HS-SCCH and the HCSN of the HS-SCCH in the TTI t, determine that then carrier wave i+1 loses HS-SCCH in TTI t+1;
So, on the carrier wave i, do not receive HCSN and be 1 HS-SCCH channel, received HCSN and be 0,2 HS-SCCH channel, namely correctly receiving the piece number is 2, the piece number of losing is 1, on the carrier wave i+1, does not receive that HCSN is 2 HS-SCCH channel, having received HCSN is 1,3 HS-SCCH channel, namely the correct piece number that receives is 2, the piece number of losing be 1. this moment carrier wave i and carrier wave i+1 on, the piece number that correctly receives altogether is 2+2=4, and the piece number of losing is 1+1=2.By the lasting statistics of a period of time, calculate total piece probability of losing.Suppose, the BLER that statistics obtains is 0.015, based on table 1, proof channel circumstance has at this moment worsened, it is 0.01 requirement that former target signal to noise ratio can not satisfy BLER, need the target signal to noise ratio of the HS-SCCH channel of all carrier waves is re-set as-8.61dB by-9.40dB, thereby finished the exterior ring power control of HS-SCCH channel.
Above-described embodiment is equally applicable to the E-AGCH channel in the multicarrier system, and the E-PUCH of E-AGCH and its scheduling is common carrier generally, for example, the shared channel of scheduling carrier wave i all is carried on the carrier frequency i, for this situation, above-described embodiment is applicable equally, does not repeat them here.
If the y2 transmitting terminal is in same carrier wave, to adopt at many shared channels of same TTI different numberings, then receiving terminal is respectively for above-mentioned a plurality of carrier waves, whether judgement all satisfies continuity in the numbering of all shared channels that current TTI receives, if, then determine not lose shared channel, otherwise, determine to lose shared channel, and lose the piece probability based on the above-mentioned a plurality of carrier waves of the unified statistics of judged result.
After above-mentioned receiving terminal is lost the piece probability statistics for above-mentioned a plurality of carrier wave unifications, also need to lose the piece probability according to what obtain, reset corresponding target signal to noise ratio for above-mentioned a plurality of carrier wave unifications.
For example: the control carrier wave i shared channel of the upper carrying of carrier wave i is HS-SCCH1, the shared channel of control carrier wave i+2 is HS-SCCH2, the shared channel of the control carrier wave i+1 of the upper carrying of carrier wave i+1 is HS-SCCH3, and transmitting terminal adopts the a2 mode to be numbered, so, after receiving terminal receives the data of transmitting terminal transmission, carry out first the CRC check, after verification is passed through, read the HCSN of each HS-SCCH, the HCSN that supposes the HS-SCCH 1 that receiving terminal receives in TTI t is that the HCSN of 0, HS-SCCH 2 is 1, the HCSN of HS-SCCH3 is 1, then:
If the HCSN of the HS-SCCH 1 that receiving terminal receives in TTI t+2 is the HCSN of 2, HS-SCCH 2 be 3, two HS-SCCH HCSN all with TTI t in the HCSN of HS-SCCH all keep continuously, then definite carrier wave i does not lose HS-SCCH in TTI t+1; If the HCSN of the HS-SCCH 3 that receiving terminal receives in TTI t+2 be 2, HS-SCCH HCSN all with TTI t in the HCSN of HS-SCCH keep continuously, determine that then carrier wave i+1 does not lose HS-SCCH in TTI t+1;
Be that the HCSN of the HS-SCCH in the HCSN of 4, HS-SCCH and the TTI t does not keep continuously if the HCSN of the HS-SCCH 1 that receiving terminal receives in TTI t+2 is the HCSN of 3, HS-SCCH2, then definite carrier wave i loses HS-SCCH in TTI t+1; If the HCSN of the HS-SCCH 3 that receiving terminal receives in TTI t+2 be 3, HS-SCCH HCSN all with TTI t in the HCSN of HS-SCCH do not keep continuously, then definite carrier wave i+1 loses HS-SCCH in TTI t+1;
So, on the carrier wave i, do not receive HCSN and be 2 HS-SCCH channel, having received HCSN is 0,1,3,4 HS-SCCH channel, namely correctly receiving the piece number is 4, the piece number of losing is 1, on the carrier wave i+1, do not receive that HCSN is 2 HS-SCCH channel, having received HCSN is 1,3 HS-SCCH channel, namely the correct piece number that receives is 2, the piece number of losing be 1. this moment carrier wave i and carrier wave i+1 on, the piece number that correctly receives altogether is 4+2=6, and the piece number of losing is 1+1=2.By the lasting statistics of a period of time, calculate and lose the piece probability.By emulation, can obtain under the different channels environment corresponding relation curve of BLER and SIR.Suppose, the BLER that statistics obtains is 0.015, based on table 1, proof channel circumstance has at this moment worsened, it is 0.01 requirement that former target signal to noise ratio can not satisfy BLER, need the target signal to noise ratio of the HS-SCCH channel of all carrier waves is re-set as-8.61dB by-9.40dB, thereby finished the exterior ring power control of HS-SCCH channel.
Above-described embodiment is equally applicable to the E-AGCH channel in the multicarrier system, and the E-PUCH of E-AGCH and its scheduling is common carrier generally, for example, the shared channel of scheduling carrier wave i all is carried on the carrier frequency i, for this situation, above-described embodiment is applicable equally, does not repeat them here.
If the y3 transmitting terminal is in same carrier wave, for in different TTI but the shared channel of controlling same carrier wave carries out numbering cycle, then receiving terminal is respectively for above-mentioned a plurality of carrier waves, whether judgement satisfies continuity in the numbering of the shared channel of a certain carrier wave of control of current TTI reception, if, then determine not lose shared channel, otherwise, determine to lose shared channel, and lose the piece probability based on the above-mentioned a plurality of carrier waves of the unified statistics of judged result.
After above-mentioned receiving terminal is lost the piece probability statistics for above-mentioned a plurality of carrier wave unifications, also need to lose the piece probability according to what obtain, reset corresponding target signal to noise ratio for above-mentioned a plurality of carrier wave unifications.
For example: the control carrier wave i shared channel of the upper carrying of carrier wave i is HS-SCCH1, the shared channel of control carrier wave i+2 is HS-SCCH2, the shared channel of the control carrier wave i+1 of the upper carrying of carrier wave i+1 is HS-SCCH3, and transmitting terminal adopts the a3 mode to be numbered, so, after receiving terminal receives the data of transmitting terminal transmission, carry out first the CRC check, after verification is passed through, read the HCSN of each HS-SCCH, the HCSN that supposes the HS-SCCH1 that receiving terminal receives in TTI t is that the HCSN of 0, HS-SCCH 2 is 1, the HCSN of HS-SCCH3 is 1, then:
If the HCSN of the HS-SCCH 1 that receiving terminal receives in TTI t+2 is the HCSN of 1, HS-SCCH 2 be 2, two HS-SCCH HCSN all with TTI t in the HCSN of HS-SCCH all keep continuously, then definite carrier wave i does not lose HS-SCCH in TTI t+1; If the HCSN of the HS-SCCH 3 that receiving terminal receives in TTI t+2 be 2, HS-SCCH HCSN all with TTI t in the HCSN of HS-SCCH keep continuously, determine that then carrier wave i+1 does not lose HS-SCCH in TTI t+1;
Be that the HCSN of the HS-SCCH in the HCSN of 3, two HS-SCCH and the TTI t all keeps continuously if the HCSN of the HS-SCCH 1 that receiving terminal receives in TTI t+2 is the HCSN of 2, HS-SCCH2, determine that then carrier wave i loses HS-SCCH in TTI t+1; If the HCSN of the HS-SCCH 3 that receiving terminal receives in TTI t+2 be 3, HS-SCCH HCSN all with TTI t in the HCSN of HS-SCCH do not keep continuously, then definite carrier wave i+1 loses HS-SCCH in TTI t+1;
So, on the carrier wave i, the shared channel of control carrier wave i, do not receive HCSN and be 1 HS-SCCH channel, received HCSN and be 0,2 HS-SCCH channel, namely correct reception piece number is 2, and the piece number of losing is 1, the shared channel of control carrier wave i+2, not receiving HCSN is 2, has received HCSN and be 1,3 HS-SCCH channel, namely the correct piece number that receives is 2, the piece number of losing is 1, and the piece number that correctly receive on the carrier wave i this moment is 2+2=4, and the piece number of losing is 1+1=2.Do not receive on the carrier wave i+1 to be numbered 2 HS-SCCH channel, received and be numbered 1,3 HS-SCCH channel, namely the correct piece number that receives is 2, the piece number of losing is that the piece number that correctly receives altogether is 4+2=6 on 1. this moment carrier wave i and the carrier wave i+1, and the piece number of losing is 2+1=3.By the lasting statistics of a period of time, calculate and lose the piece probability.By emulation, can obtain under the different channels environment corresponding relation curve of BLER and SIR.Suppose, the BLER that statistics obtains is 0.015, based on table 1, proof channel circumstance has at this moment worsened, it is 0.01 requirement that original target signal to noise ratio can not satisfy BLER, need the target signal to noise ratio of the HS-SCCH channel of all carrier waves is re-set as-8.61dB by-9.40dB, thereby finished the exterior ring power control of HS-SCCH channel.
