But the inventor finds that there are the following problems at least in the prior art in the invention process:
The ropy zone of interface aloft, though using two transceivers as a transceiver, the base station can improve the air interface quality, but for the user that under the situation that does not adopt PBT or diversity technique, just can receive than the wireless signal of good quality, for example nearer apart from BTS user comes two transceivers to transmit the reduction that data can cause resource waste, network capacity for these users as a transceiver.

In this implementation, judge whether the quality of the air interface of the current use of terminal reaches pre-conditioned earlier, if reach described pre-conditioned, then use a transceiver to send data message to described terminal; If do not reach described pre-conditioned, then superpose and improve carrier power, and use this (promptly after the stack) carrier wave that has improved power to described terminal transmission data message by carrier wave with at least two transceiver transmit.
Fig. 2 is a kind of method flow diagram that uses the carrier wave transmission data message of stack that the embodiment of the invention provides.Concrete steps shown in Figure 2 comprise:
Step 21: at first, judge that whether the quality of the air interface of the current use of terminal reaches pre-conditioned, comprises whether the mass value of the air interface of judging the current use of terminal is higher than set point earlier; If be higher than described set point, then carry out step 22; If be not higher than described set point, then carry out step 23;
Wherein, the mass value of air interface can include but not limited to: the level value of the terminal wireless signal of receiving, or the ber value of the terminal wireless signal of receiving, or the snr value of the terminal wireless signal of receiving etc.; For example, when specifically using, can preestablish the level value of signal,, think that then the air interface quality is better, carry out step 22 if the level value of the terminal wireless signal of receiving is higher than the level value of setting; If be not higher than the level value of setting, think that then the air interface quality needs to improve, carry out step 23; Certainly, also can preestablish ber value, snr value of terminal wireless signal etc. in the lump, if ber value, the snr value of the terminal wireless signal of receiving all do not reach each set point, then carry out step 23, if all reach then and carry out step 22, if wherein have only one to reach set point, then can carry out step 23 or 22 according to specific circumstances; Therefore, can take to be not limited to above-mentioned described multiple mode during specific implementation sets;
Step 22:, use a transceiver to send data message to described terminal when described terminal sends data message;
Step 23: use at least two transceivers, with the carrier wave stack of the identical data information of carrying of at least two transceivers output, the carrier wave after obtaining superposeing, and send this carrier wave to described terminal; Specifically can comprise: the phase place of power output maximum when calculating at least two carrier power stacks earlier, use the time slot of channel in described terminal, the frequency that transmits and the phase place of at least two transceivers are set, obtain at least two and have identical frequency, the carrier wave of the phase place of power output maximum during stack, during specific implementation, the frequency that transmit of the time slot that can use channel in described terminal by at least two transceivers of phase-locked loop setting (for example, be as the criterion with one of them frequency that transmits, adjust the frequency that transmits of other transceiver, obtain identical the transmitting of the frequency that transmits a plurality of and this transceiver) and phase place; Make described at least two carrier waves all carry identical data message simultaneously, and will carry identical data information described when having identical frequency, stack the carrier wave stack back of the phase place of power output maximum send;

Wherein, the mass value of air interface can include but not limited to: the level value of the terminal wireless signal of receiving, or the ber value of the terminal wireless signal of receiving, or the snr value of the terminal wireless signal of receiving etc.; For example, when specifically using, can preestablish the level value of signal,, think that then the air interface quality is better, carry out step 42 if the level value of the terminal wireless signal of receiving is higher than the level value of setting; If be not higher than the level value of setting, think that then the air interface quality needs to improve, carry out step 43; Certainly, also can preestablish ber value, snr value of terminal wireless signal etc. in the lump, if ber value, the snr value of the terminal wireless signal of receiving all do not reach each set point, then carry out step 43, if all reach then and carry out step 42, if wherein have only one to reach set point, then can carry out step 43 or 42 according to specific circumstances; Therefore, can take to be not limited to above-mentioned described multiple mode during specific implementation sets;
Step 42:, use a transceiver to send data message to described terminal when described terminal sends data message;
Step 43: use at least two transceivers, make the carrier wave of at least two transceiver outputs all carry identical data message, and send described at least two carrier waves that carry identical data information simultaneously to described terminal; Specifically can comprise: the time slot that uses channel in described terminal, the frequency that transmits of at least two transceivers is set, obtain at least two with carrier wave frequently, during specific implementation, the crack (or is as the criterion with the frequency that transmits of one of them transceiver by the frequency that transmits that phase-locked loop is provided with transceiver at this moment, adjust the frequency that transmits of other transceiver, to obtain a plurality of and identical the transmitting of this transceiver transmit signal frequency point); And make described carrier wave carry identical data message, then described described at least two carrier waves with frequency that carry identical data information are sent simultaneously;
