For solving problems of the prior art; signaling method when proposing a kind of adjacent frequency bands among the present invention; when the pairing FDD adjacent frequency bands of the pairing TDD frequency range of TDD system and FDD system; be used for the folk prescription that the FDD system carries out in the part-time and send being arranged at boundary belt between TDD frequency range and the FDD frequency range in the prior art, thereby improve the utilance of frequency resource to signal.Specific implementation comprises: the signalling in TDD frequency range and FDD frequency range utilized described boundary belt to carry out signal by the FDD system and sends in the consistent time period; In addition, the signalling in TDD frequency range and FDD frequency range can be handled by existing mode in the inconsistent time period, did not promptly carry out the transmitting-receiving of any signal in described boundary belt.
In addition, in the scheme of the present invention, the uplink-downlink configuration information of TDD system need be known in advance in the FDD system, will as the TDD system at which time period transmission upward signal, which time period to give capable signal etc. in, like this, the FDD system can according to these information to determine which be the TDD frequency range time period with the FDD frequency range in signalling to the consistent time period, which is that signalling in TDD frequency range and the FDD frequency range is to the inconsistent time period.
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
The flow chart of signaling method first embodiment of Fig. 3 during for adjacent frequency bands of the present invention.Suppose that the FDD frequency range in the present embodiment is the FDD band downlink.As shown in Figure 3, may further comprise the steps:
Step 301:FDD system obtains the uplink-downlink configuration information of TDD system.
Concrete obtain manner can be: the FDD system receives and preserves the uplink-downlink configuration information of the TDD system of artificial input; Perhaps, by predefined interface between FDD system and the TDD system, the FDD system receives and preserves the uplink-downlink configuration information that the TDD system sends.Certainly, only for illustrating,, can reach same purpose herein, also be fine if adopt other mode.
Step 302:FDD system determines that according to the uplink-downlink configuration information of the TDD system that gets access to the TDD system utilizes the TDD frequency range to carry out the time period of downstream signal transmission and the time period of carrying out the upward signal transmission.
For the TDD system, sometime the section in, it may utilize the TDD frequency range to carry out the transmission of downstream signal, and in next time period, then may utilize the TDD frequency range to carry out the transmission of upward signal.In this step, the FDD system is exactly will be according to the uplink-downlink configuration information of the TDD system that obtains, determine which time period and carry out the time period that upward signal sends for the TDD system utilizes the TDD frequency range, which carries out the time period that upward signal sends for the TDD system utilizes the TDD frequency range time period.
Step 303: utilize the TDD frequency range to carry out in the time period of downstream signal transmission in the TDD system, the boundary belt that the utilization of FDD system is arranged between TDD frequency range and the FDD frequency range carries out the downstream signal transmission; Utilize the TDD frequency range to carry out in described boundary belt, not carrying out the transmitting-receiving of any signal in the time period of upward signal transmission in the TDD system.
Because the FDD frequency range in the present embodiment is the FDD band downlink, so, utilize the TDD frequency range to carry out in time period that downstream signal sends in the TDD system, the interior signalling of FDD frequency range and TDD frequency range is to being consistent, that is to say, can not have the cross interference problem between the two paths of signals.In this case; there has been meaning in the boundary belt that is arranged between TDD frequency range and the FDD frequency range with regard to too big; can cause the waste of frequency resource on the contrary; so in the present embodiment; utilize the TDD frequency range to carry out in the time period of downstream signal transmission in the TDD system; by the FDD system this boundary belt is used, utilize it to carry out the transmission of downstream signal.And utilize the TDD frequency range to carry out in the time period of upward signal transmission in the TDD system; signalling in FDD frequency range and the TDD frequency range is to being inconsistent; that is to say; can there be the cross interference problem between the two paths of signals; so in this case; the boundary belt that is arranged between TDD frequency range and the FDD frequency range then needs to continue to keep, and does not allow to carry out any signal transmitting and receiving in this boundary belt.
Below in conjunction with accompanying drawing, the specific implementation of this step is described in further detail:
Fig. 4 utilizes the mode schematic diagram for the boundary belt among the inventive method first embodiment.Can visually see from Fig. 4, utilize the TDD frequency range to carry out in the time period of downstream signal transmission in the TDD system, the FDD system utilizes boundary belt to carry out the transmission of downstream signal; And utilize the TDD frequency range to carry out in time period that upward signal sends in the TDD system, the effect that boundary belt played will with prior art in identical, can be not occupied.
Further, Fig. 5 is the signalling formula schematic diagram among the inventive method first embodiment.F1 wherein, f2 and f3 be corresponding TDD frequency range, boundary belt and FDD band downlink respectively; Fritter on f1 and the f2 is represented the different time periods respectively; The fritter that dotted line marked on the f2 then represents not carry out the time period of any signal transmitting and receiving.As shown in Figure 5, in the TDD frequency range, suppose that carrying out signal according to descending, the up mode that replaces sends, so obvious, the TDD system utilizes the TDD frequency range to carry out the time period of upward signal transmission with the fritter that dotted line marked among the corresponding f2 among the f1.
Because the downlink resource on the f2 is discontinuous in time; so in actual applications; when the FDD system utilizes boundary belt to carry out the signal transmission; pairing other FDD frequency range of frequency range that can this boundary belt is shared and FDD system; as the f3 use that condenses together, promptly jointly as the descending available bandwidth of FDD system.Like this, in some time period (being that the TDD system utilizes the TDD frequency range to carry out the time period that downstream signal sends), the descending available bandwidth of FDD system will be greater than up available bandwidth, thereby forms the asymmetric transmission bandwidth of up-downgoing; In other words, if each frequency range is called a carrier wave, in some time period, the available descending carrier number (boundary belt adds the FDD frequency range) of FDD system will be greater than available up-link carrier number so.Like this, for some scene that needs big downlink bandwidth, promptly provide a kind of settling mode preferably among the present invention.
The flow chart of signaling method second embodiment of Fig. 6 during for adjacent frequency bands of the present invention.Suppose that the FDD frequency range in the present embodiment is the FDD uplink band.As shown in Figure 6, may further comprise the steps:
Step 601:FDD system obtains the uplink-downlink configuration information of TDD system.
Step 602:FDD system determines that according to the uplink-downlink configuration information of the TDD system that gets access to the TDD system utilizes the TDD frequency range to carry out the time period of downstream signal transmission and the time period of carrying out the upward signal transmission.
The specific implementation of step 601～602 is identical with the specific implementation of step 301～302, repeats no more.
Step 603: utilize the TDD frequency range to carry out in the time period of upward signal transmission in the TDD system, the boundary belt that the utilization of FDD system is arranged between TDD frequency range and the FDD frequency range carries out the upward signal transmission; Utilize the TDD frequency range to carry out in described boundary belt, not carrying out the transmitting-receiving of any signal in the time period of downstream signal transmission in the TDD system.
Because the FDD frequency range in the present embodiment is the FDD uplink band, so, utilize the TDD frequency range to carry out in time period that upward signal sends in the TDD system, the interior signalling of FDD frequency range and TDD frequency range is to being consistent, that is to say, can not have the cross interference problem between the two paths of signals.In this case; there has been meaning in the boundary belt that is arranged between TDD frequency range and the FDD frequency range with regard to too big; can cause the waste of frequency resource on the contrary; so in the present embodiment; utilize the TDD frequency range to carry out in the time period of upward signal transmission in the TDD system; by the FDD system this boundary belt is used, utilize it to carry out the transmission of upward signal.And utilize the TDD frequency range to carry out in the time period of downstream signal transmission in the TDD system; signalling in FDD frequency range and the TDD frequency range is to being inconsistent; that is to say; can there be the cross interference problem between the two paths of signals; so in this case; the boundary belt that is arranged between TDD frequency range and the FDD frequency range then needs to continue to keep, and does not allow to carry out any signal transmitting and receiving in this boundary belt.
Below in conjunction with accompanying drawing, the specific implementation of this step is described in further detail:
Fig. 7 utilizes the mode schematic diagram for the boundary belt among the inventive method second embodiment.Can visually see from Fig. 7, utilize the TDD frequency range to carry out in the time period of upward signal transmission in the TDD system, the FDD system utilizes boundary belt to carry out the transmission of upward signal; And utilize the TDD frequency range to carry out in time period that downstream signal sends in the TDD system, the effect that boundary belt played will with prior art in identical, can be not occupied.
Further, Fig. 8 is the signalling formula schematic diagram among the inventive method second embodiment.F4 wherein, f5 and f6 represent TDD frequency range, boundary belt and FDD upstream band respectively; Fritter on f4 and the f5 is represented the different time periods respectively; The fritter that dotted line marked on the f5 then represents not carry out the time period of any signal transmitting and receiving.As shown in Figure 8, in the TDD frequency range, suppose that carrying out signal according to descending, the up mode that replaces sends, so obvious, the TDD system utilizes the TDD frequency range to carry out the time period of downstream signal transmission with the fritter that dotted line marked among the corresponding f5 among the f4.
Similar with f2; because the ascending resource on the f5 is discontinuous in time, so in actual applications, when the FDD system utilizes boundary belt to carry out the signal transmission; pairing other FDD frequency range of frequency range that can this boundary belt is shared and FDD system is as the f6 use that condenses together.Like this, in some time period, the up available bandwidth of FDD system will be greater than descending available bandwidth, thereby forms the asymmetric transmission bandwidth of up-downgoing; In other words, if each frequency range is called a carrier wave, in some time period, the available up-link carrier number of FDD system will be greater than available descending carrier number so.
Based on said method, Fig. 9 is the composition structural representation of the sender unit embodiment of frequency band of the present invention when adjacent.As shown in Figure 9, this device comprises:
