In the declarative procedure below, implement to describe from the cooperation of transmitter side and receiver side earlier, describe from the enforcement of transmitter side and receiver side respectively at last, but this does not also mean that the two must cooperate enforcement, 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 the two is used in combination, can obtain better technique effect.
Below in conjunction with Figure of description the embodiment of the invention is described in further detail.
As shown in Figure 1, the system of embodiment of the invention transmission command word comprises: transmitting apparatus 10 and receiving equipment 20.
Transmitting apparatus 10 is used for the command word that definite needs send, and information bit is carried out multiplexing process and chnnel coding processing, the information bit after command word and the processing is carried out Burst (burst) encapsulate the back transmission.
Receiving equipment 20 is used for the data that receive are decoded, and goes out command word from decoded extracting data.
Wherein, if transmitting apparatus 10 sends by up channel, then 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, then 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.
Below the branch situation describe:
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 of receiving from network side.
Wherein, the network side high level is (such as RNC (Radio Network Controller; Radio network controller)), determine the command word number of repetition, and, need to determine the command word of transmission according to the command word number of repetition of determining according to command word performance parameter and channel property parameter.
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 then 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, the notice terminal can be passed through high-level signaling (such as RRC (Radio Resource Control, Radio Resource control) signaling) notice.
Such as setting-up time is 1s, then can arrange the every 5ms of UE in advance and report the channel property parameter value one time, 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 then, be the corresponding relation of network side high level, promptly can determine the curve of similar Fig. 6 according to command word performance parameter value and channel property parameter value and channel property parameter value.
Because the command word number of repetition is more little can save transfer resource more, so preferable, 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, after from alternative number of times, having selected a number of times,, judge whether the alternative number of times of selecting satisfies the information performance requirement according to the code check value of channel property parameter and information bit part; 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, network side is high-rise determines information bit code check value partly according to the alternative number of times of determining, judges that according to channel property parameter whether the code check value of information bit part can satisfy performance requirement, promptly determines whether and can satisfy according to similar Fig. 7 then.If of course, the alternative number of times that then will select is as the command word number of repetition; Otherwise, from remaining alternative number of times, select an alternative number of times (preferable, from remaining alternative number of times, select minimum alternative number of times), and continue according to channel property parameter and information bit code check value partly, judge whether the alternative number of times of selecting satisfies the information performance requirement, up to the alternative number of times that finds to meet the demands.If all alternative number of times all can't meet the demands, then the mode according to prior art sends command word.
Specifically can determine the code check value of information bit part according to formula one.
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 number; Num
AfterCodeIt is the bit number behind the coding; Num
PhyIt is the bit number that physical channel can carry.
With channel is that E-AGCH is an example, and fixedly the SS command word is 2bits, and modulation system still adopts the 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.The network side high level can be selected one 3 from 3,4 and 5 then.
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 the E-AGCH information bit shown in Figure 7 curve of correspondence when 0.316 code check performance is to meet the demands during for-2dB.Then determine Num
