E-baseCarry out scheduling of resource, wherein P
E-baseAdjust according to the TPC command word that strengthens the upper carrying of special uplink channel (Enhanced dedicated channel, E-DCH) absolute grant channel (E-DCH Absolute Grant Channel, E-AGCH).
If it is inconsistent that the TPC command word that terminal solves and base station send, cause the P of base station and terminal maintenance
E-baseDifference occuring, and then affected the effective scheduling of network side to terminal, thereby causes the deterioration of systematic function.
SS (Synchronization Shift, simultaneous bias) command word and TPC command word are similar, are also to carry by E-AGCH, if the SS command word that terminal solves and base station transmission is inconsistent, cause upstream data can't reach chip (chip) level synchronous, increase intersymbol interference.
In sum, in the mobile channel environment, the performance of command word can not be guaranteed at present, thereby has reduced accuracy and the validity of base station scheduling and increased intersymbol interference, reduces the throughput of system.

Wherein, the first command word in the embodiment of the present invention can be the TPC command word, can be also the SS command word, can also be other command words that need to transmit.
In declarative procedure below, first implement to describe from the cooperation of transmitter side and receiver side, describe from the enforcement of transmitter side and receiver side respectively at last, but this does not also mean that both and must cooperation implement, in fact, when transmitter side and receiver side separate when implementing, also solved respectively in transmitter side, the existing problem of receiver side, when just both being combined with, can obtain better technique effect.
Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
As shown in Figure 1, the system of embodiment of the present invention transmission command word comprises: transmitting apparatus 10 and receiving equipment 20.
Transmitting apparatus 10 is used for definite command word that needs transmission, and information bit is carried out multiplexing process and chnnel coding processing, and the information bit after command word and processing is carried out the rear transmission of Burst (burst) encapsulation.
Receiving equipment 20 is used for the decoding data to receiving, and goes out command word from decoded extracting data.
Wherein, if transmitting apparatus 10 sends by up channel, transmitting apparatus 10 is terminals, and receiving equipment 20 is base stations, and command word is the TPC command word;
If transmitting apparatus 10 sends by down channel, transmitting apparatus 10 is base stations, and receiving equipment 20 is terminals, and command word is the SS command word, or the TPC command word, or TPC command word and SS command word.
The below's minute situation describes:
Situation one, transmitting apparatus 10 send by down channel or send by up channel.
Transmitting apparatus 10 need to determine the command word of transmission according to the command word number of repetition from network side of receiving.
Wherein, network side is high-rise (such as RNC (Radio Network Controller; Radio network controller)) according to command word performance parameter and channel property parameter, determine the command word number of repetition, and according to the command word number of repetition of determining, need to determine the command word of transmission.
Concrete, the network side high level can be determined the command word number of repetition according to command word performance parameter and channel property parameter, and according to the command word number of repetition of determining, need to determine the command word of transmission.
Determine that such as network side is high-rise the command word number of repetition is 3 times, a command word is 10, and the command word that needs to send is exactly 101010.
In force, the network side high level determines to satisfy the alternative number of times of channel performance requirement according to command word performance parameter and channel property parameter, selects an alternative number of times as the command word number of repetition from all alternative number of times of determining.
Concrete network side high level determines to satisfy the alternative number of times of channel performance requirement according to command word performance parameter and channel property parameter, all alternative number of times of determining can be formed a set.
The command word performance parameter includes but not limited to BER.
Channel property parameter includes but not limited to SNR (signal to noise ratio), SIR (Signal-to-InterferenceRatio, signal interference ratio), signal strength signal intensity and Block Error Rate.
Wherein, NodeB (or UE) measures and to the high-rise reporting channel performance parameter of network side, the network side high level needs informing base station and terminal after having determined the command word number of repetition, notification terminal can pass through high-level signaling (such as RRC (Radio Resource Control, Radio Resource is controlled) signaling) notice.
Such as setting-up time is 1s, can arrange in advance the every 5ms of UE and report the channel property parameter value one time, then the network side high level just can be determined TPC command word number of repetition according to command word performance parameter value and channel property parameter value, be the network side high level according to the corresponding relation of command word performance parameter value and channel property parameter value and channel property parameter value, namely can determine the curve of similar Fig. 6.
More can save transfer resource because the command word number of repetition is more little, so better, the network side high level selects minimum alternative number of times as the command word number of repetition from all alternative number of times of determining.
For under the prerequisite that guarantees the command word transmission performance, the performance of further guarantee information bit, selected a number of times from alternative number of times after, according to the code check value of channel property parameter and information bit part, whether the alternative number of times that judgement is selected satisfies the information performance requirement; If satisfy, with the alternative number of times selected as the command word number of repetition; If do not satisfy, the alternative number of times that deletion has been selected is selected an alternative number of times from remaining alternative number of times, and returns and continue to judge whether the alternative number of times of selecting satisfies the step of information performance requirement.
Concrete, then the high-rise code check value of determining the information bit part according to the alternative number of times of determining of network side judges that according to channel property parameter whether the code check value of information bit part can satisfy performance requirement, namely determines whether and can satisfy according to similar Fig. 7.If the alternative number of times that of course, will select is as the command word number of repetition; Otherwise, select an alternative number of times (better from remaining alternative number of times, select minimum alternative number of times from remaining alternative number of times), and continue according to channel property parameter and information bit code check value partly, whether the alternative number of times that judgement is selected satisfies the information performance requirement, until find an alternative number of times that meets the demands.If all alternative number of times all can't meet the demands, the mode according to prior art sends command word.
Specifically can determine according to formula one the code check value of information bit part.
Wherein, β is the code check value of information bit part; Num
TPCIt is the bit number that takies according to the TPC command word that the needs that the alternative number of times of the TPC that selects is determined send; Num
SSIt is the bit number that takies according to the SS command word that the needs that the alternative number of times of the SS that selects is determined send; Num
BeforCodeIt is the control channel information bit; Num
AfterCodeIt is the bit number after coding; Num
PhyIt is the bit number that physical channel can carry.
Take channel be E-AGCH as example, fixedly the SS command word is 2bits, modulation system still adopts QPSK modulation.The command word performance parameter of TPC is BER (Bit error ratio, the error rate), command word performance parameter value BER=0.001.
Suppose that current signal to noise ratio (SNR) is-2dB, according to the corresponding relation of Fig. 6, TPC code check this moment (TPCCodeRate) is 1/3,1/4,1/5 o'clock, i.e. TPC number of repetition Num
TPCBe 3,4,5 all to satisfy performance requirement.Then the network side high level can be selected one 3 from 3,4 and 5.
Num for E-AGCH type2
BeforCode=54bits, Num
Phy=176bits determines that according to formula one the code check value of information bit part is 0.316, finds out in signal to noise ratio that according to E-AGCH information bit shown in Figure 7 corresponding curve when 0.316 code check performance is to meet the demands during for-2dB.Determine Num
TPC=3.

The below's minute situation describes:
Situation one, transmitter side send by down channel or send by up channel.
Transmitter side need to determine the command word of transmission according to the command word number of repetition from network side of receiving.
Wherein, network side high-rise (such as RNC) is determined the command word number of repetition according to command word performance parameter and channel property parameter, and according to the command word number of repetition of determining, need to determine the command word of transmission.
Concrete, the network side high level can be determined the command word number of repetition according to command word performance parameter and channel property parameter, and according to the command word number of repetition of determining, need to determine the command word of transmission.
In force, the network side high level determines to satisfy the alternative number of times of channel performance requirement according to command word performance parameter and channel property parameter, selects an alternative number of times as the command word number of repetition from all alternative number of times of determining.
Concrete network side high level determines to satisfy the alternative number of times of channel performance requirement according to command word performance parameter and channel property parameter, all alternative number of times of determining can be formed a set.
Wherein, NodeB (or UE) measures and to the high-rise reporting channel performance parameter of network side, the network side high level needs informing base station and terminal after having determined the command word number of repetition, and notification terminal can pass through high-level signaling (such as the RRC signaling) notice.
More can save transfer resource because the command word number of repetition is more little, so better, the network side high level selects minimum alternative number of times as the command word number of repetition from all alternative number of times of determining.
For under the prerequisite that guarantees the command word transmission performance, the performance of further guarantee information bit, selected a number of times from alternative number of times after, according to the code check value of channel property parameter and information bit part, whether the alternative number of times that judgement is selected satisfies the information performance requirement; If satisfy, with the alternative number of times selected as the command word number of repetition; If do not satisfy, the alternative number of times that deletion has been selected is selected an alternative number of times from remaining alternative number of times, and returns and continue to judge whether the alternative number of times of selecting satisfies the step of information performance requirement.
