Wherein, first command word in the embodiment of the invention can be the TPC command word, also can be the SS command word, can also be other command words that need transmit.
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, be used for determining respectively first command word and second command word position at time slot, with position, the part or all of position of second command word, on the correspondence position of time slot, fill command word, and send to receiving equipment 20 by channel as first command word;
Receiving equipment 20, determine first command word and the position of second command word in time slot respectively, with position, the part or all of position of second command word, on the position of the position of first command word and second command word, receive data respectively from transmitting apparatus 10 as first command word.
Wherein, channel is a up channel, and first command word is the TPC command word, and second command word is the SS command word; Transmitting apparatus 10 is terminals, and receiving equipment 20 is base stations.
Channel is a down channel, if first command word is the TPC command word, second command word is the SS command word; If first command word is the SS command word, second command word is the TPC command word; Transmitting apparatus 10 is base stations, and receiving equipment 20 is terminals.
Wherein, network side high level (such as RNC equipment) can be to terminal transmitting channel performance change announcement information slowly after definite channel performance changes slowly, and the informing base station channel performance changes slowly.
Concrete, the network side high level is repeatedly determined the channel property parameter value in setting-up time, and determines the poor of adjacent twice channel property parameter value; If in the difference of all channel property parameter values not the quantity greater than the difference of the channel property parameter value of first threshold be not less than second threshold value, determine that then channel performance changes slowly; If in the difference of all channel property parameter values not greater than the quantity of the difference of the channel property parameter value of first threshold less than second threshold value, it is not slow to determine that then channel performance changes.
The high-rise channel property parameter value of determining of network side is by base station and/or terminal to report.
Such as setting-up time is 1s, then can arrange the every 5ms of terminal in advance and report the channel property parameter value one time, the network side high level sorts to all channel property parameter values of receiving in the 1s according to the order that receives then, and calculates the absolute value of the difference of adjacent two channel property parameter values.If in the absolute value of the difference of all not the quantity greater than the difference of the channel property parameter value of first threshold be not less than second threshold value, determine that then channel performance changes slowly; Otherwise it is not slow to determine that channel performance changes.
The first threshold here can be set as required; Second prefabricated can the setting according to the time of setting, receive 4 times such as always meeting together in the setting-up time, then difference has altogether 3 times, all differences all are not more than the just definite channel performance variation of first threshold slowly if desired, can set second threshold value is 3, partly be not more than first threshold if desired in all differences and just can determine that channel performance changes slowly, then can set second threshold value is 1 or 2.
The channel property parameter value here includes but not limited to a kind of among the following parameters value:
SNR (signal to noise ratio), SIR (Signal-to-Interference Ratio, signal interference ratio), signal strength signal intensity and Block Error Rate.
The concrete time of setting, the cycle that reports can be stipulated in agreement, also can be consulted by network side and end side; Can also notify end side by network side.
Certainly, determine whether the channel performance variation slowly also can be realized by the base station.
Base station and terminal are after definite channel performance changes slowly, all with the position as first command word, the part or all of position of second command word.
Concrete, if channel is a up channel, then transmitting apparatus 10 receive change slowly announcement information from the network side channel performance after, determine that channel performance changes slowly, with position, the part or all of position of second command word as first command word;
If channel is a down channel, transmitting apparatus 10 determines that according to the high level notice channel performance changes slowly (if determine by the base station whether channel performance changes slow, transmitting apparatus determines that according to the channel property parameter value channel performance changes slowly) after, with position, the part or all of position of second command word as first command word.
Because transmitting apparatus 10 is with the position as first command word, the part or all of position of second command word, so receiving equipment 20 also needs to be consistent with transmitting apparatus 10.
In force, the network side high level can be determined concrete occupancy mode, and occupancy mode comprises it being that the TPC command word takies the SS command word, or the SS command word takies the TPC command word; The concrete number of engaged position; Specifically take which position; The cycle that takies (if channel variation is slower, can also reduce the transmission cycle of TPC and SS command word) etc. can determine specifically to take the information of which position.
Concrete, can preestablish the corresponding relation of occupancy mode and announcement information, then according to the occupancy mode of determining, send corresponding announcement information respectively to terminal and base station and get final product.
Accordingly, terminal and base station be according to the corresponding relation of occupancy mode and announcement information, determines the occupancy mode of the announcement information correspondence received, thereby can guarantee that receiving equipment 20 and transmitting apparatus 10 are consistent.
Certainly, determine that specifically occupancy mode also can be definite by the base station, and the notice terminal.
Consistent with transmitting apparatus 10 in order to guarantee receiving equipment 20, except top method, also having a kind of method is the corresponding relation of the cycle of setting up in advance and occupancy mode.
The corresponding relation of cycle and occupancy mode can be the corresponding relation of periodicity and occupancy mode, and such as can odd cycle taking the position of SS command word by the TPC command word, even cycle is taken the position of TPC command word by the SS command word; Can also replace in M cycle, suppose M=5, then 1～5 cycle was taken the position of SS command word by the TPC command word; 6～10 cycles took the position of TPC command word by the SS command word, and the like.Receiving equipment 20 and transmitting apparatus 10 can be determined corresponding occupancy mode according to the current cycle like this.
The corresponding relation of cycle and occupancy mode can also be the corresponding relation of subframe and occupancy mode in the cycle, such as the E-AGCH channel is in the example, determine that the cycle that TPC/SS takies the SS/TPC command word is a N subframe, preceding M the subframe in each cycle repeats TPC and takies whole SS position, back N-M subframe repeats SS and takies whole TPC position, be that 0 SS bit of 4 TPC bits or 4 SS bits, 0 TPC bit are arranged among the Burst.
Setting up the corresponding relation of cycle and occupancy mode can stipulate in agreement, also can be consulted to determine by network side and end side, can also notify end side by network side.Certainly, the corresponding relation of cycle and occupancy mode also can upgrade as required.
Wherein, the position that takies second command word is first command word of repetition.Promptly the TPC command word of Chong Fuing takies the position of SS command word according to certain pattern, and the SS command word of repetition also from the flat takies the position of TPC command word, specifically can be referring to Fig. 6.

Take the part position and take whole position classes seemingly, do not repeat them here.
Because corresponding at least one time slot of first command word and second command word, if promptly corresponding time slot, then elder generation determines the bit information of time slot correspondence, and all the other bits repeat the bit information of time slot correspondence; If corresponding a plurality of time slot is determined the bit information of each time slot correspondence, repeat the bit information of time slot correspondence then.
Wherein, transmitting apparatus 10 is determined each bit time slot corresponding in first command word and second command word, according to the corresponding relation of time slot that sets in advance and position, determine the position of time slot correspondence, the numerical value of the bit of time slot correspondence is filled on the position of this time slot correspondence.
Such as first command word 6 positions (the part or all of position that comprises second command word) are arranged, first command word takies 2 bits, supposes it is 10, and then 6 positions can be 101010; If 5 positions (the part or all of position that comprises second command word), then 5 positions can be 10101.
Accordingly, receiving equipment 20 is known the position of first command word and the position of second command word, and receives data respectively on the position of the position of first command word and second command word; According to the position of time slot correspondence, the locational data extract of identical time slot correspondence is come out to merge processing then, just obtain the command word of this time slot correspondence.
