Embodiment
In the cellular system in future, a kind of possible application mode is the pairing of TDD carrier wave (be about to the TDD carrier wave and divide into TDD up-link carrier and the use of TDD descending carrier), and adopts special TDD time slot proportion setting.For example in the TDD up-link carrier, the uplink and downlink timeslot proportioning is 4: 1, and 4 ascending time slots of the every transmission continuously of expression (Transmission Time Interval, TTI) a descending TTI is transmitted in the back; And for example in the TDD descending carrier, the uplink and downlink timeslot proportioning is 0: 5, and expression does not transmit up TTI, and whole TDD descending carrier only is used to transmit descending TTI.Corresponding TDD carrier wave pairing schematic diagram as shown in Figure 1.Among Fig. 1, U represents ascending time slot, and D shows descending time slot.
Two TDD carrier wave pairings are used in employing, are similar to FDD system traditional in the prior art, but have difference with traditional F DD system: in traditional FDD system, only transmit ascending time slot in the up-link carrier, only transmit descending time slot in the descending carrier.And when adopting the pairing of TDD carrier wave, might transmit descending time slot in the up-link carrier, also might transmit ascending time slot in the descending carrier; This makes that when adopting the pairing of TDD carrier wave, the up-downgoing band bandwidth may be different, and pairing carrier wave isolation size also can't be determined.Like this, portable terminal can't obtain its corresponding TDD uplink carrier information according to the TDD descending carrier that receives.
In addition, in the cellular system in future, also may use carrier aggregation technology and (be about to two or together more than two carrier aggregation, the technology that while uses as system carrier), wherein the existing TDD carrier wave might be polymerized on the FDD frequency range and use, such as the FDD carrier wave is f1 and f2, and the TDD carrier wave is f3, f4 and f5; At this moment, if descending carrier is f1 and f3, up-link carrier is f2, f4 and f5, because f1 and f2 are the FDD carrier wave of pairing, therefore, portable terminal obtains up-link carrier f2 information according to fixedly unpaired message and the duplexing isolation of descending carrier f1 and up-link carrier f2; But portable terminal but can't obtain the carrier information of up-link carrier f4 and f5.
According to above description, in the cellular system in future, for adopting the pairing of TDD carrier wave to use, when perhaps adopting carrier aggregation, also do not have corresponding implementation method, make portable terminal can obtain uplink carrier information, and send upward signal to the base station according to the up-link carrier that obtains.
