Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, it is described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The present invention is directed to the problem of the not reciprocity FDD frequency usage waste caused of upstream traffic and downlink traffic in existing technology with poor efficiency, it is provided that the subframe scheduling method of a kind of frequency division duplex system, as shown in Figure 1, comprising:
Step 11: according to portfolio that is current and terminal transmission, producing can by the change indication information of the flexible duplex subframe of flexible dispatching;
Step 12: according to described change indication information, change duplex use-pattern in described flexible duplex subframe.
The subframe scheduling method of the described frequency division duplex system that the embodiment of the present invention provides is by the portfolio according to current and terminal transmission, generation can by the change indication information of the flexible duplex subframe of flexible dispatching, and according to described change indication information, change duplex use-pattern in described flexible duplex subframe, solves upstream traffic and the not reciprocity FDD frequency usage caused of downlink traffic is wasted and the problem of poor efficiency.
Concrete, according to portfolio that is current and terminal transmission, generation can be comprised by the step of change indication information of the flexible duplex subframe of flexible dispatching: when portfolio that the is current and transmission of terminal one direction exceedes the party's sub-frame transmission threshold value upwards, determines to meet the part subframe that requires from the current current direction with terminal as can by the flexible duplexing subframe of flexible dispatching transmitting. Part subframe may be idle subframe also may be the subframe dispatching out (sparing) in order to meet business demand.
Wherein, the change indication information of described flexible duplexing subframe comprises: the triggering time delay information of the direction modification information of duplex subframe, flexibly duplex subframe and the persistence length information of flexible duplex subframe flexibly. Flexible duplex changes directional information and refers to that the direction informing user flexibility duplex is that sub-frame of uplink overturns as descending or descending sub frame overturn as upper row; Duplex triggering time delay information refers to and informs that user's system after how many subframes starts to trigger duplex configuration flexibly (if broadcast side does not adopt default value) flexibly; Duplex persistence length information refers to and informs that user flexibility duplex continuous overturning continues how many subframes (if broadcast side does not adopt default value) flexibly.
In order to reach effect easily when reality uses, wherein, the change indication information of described flexible duplex subframe can also for presetting duplex sub-frame configuration MODE NUMBER flexibly, namely the form of duplex configuration MODE NUMBER flexibly is adopted: set a series of flexible duplex inverted pattern in advance and be numbered, base station broadcast informs terminal number information, that is by the direction modification information of duplex subframe flexibly, the triggering time delay information of duplex subframe and the persistence length information fusion of flexible duplex subframe are that coding form informs user related information flexibly, such as: base station informs that upper line frequency rate will be configured to descending pattern for " 0110001100 " by terminal, then base station will the 1st, 2, 6, the upper line frequency rate of 7 work song frames transmits downlink information or base station informs that the pattern that terminal will be gone on descending frequency being configured to is " 0010000100 ", then base station will the 2nd, the descending frequency of 7 work song frames receives uplink information.
Exist in actual applications and sub-frame of uplink is configured to descending sub frame or descending sub frame is configured to sub-frame of uplink two kinds of situations, so, the embodiment of the present invention is also corresponding provides two kinds of measures, the first: when portfolio that the is current and transmission of terminal one direction exceedes the party's sub-frame transmission threshold value upwards, the part subframe determining to meet requirement from current direction that is current and terminal transmitting is as being comprised by the step of the flexible duplex subframe of flexible dispatching: obtain portfolio that is current and terminal uplink transmission; If the portfolio of uplink exceedes sub-frame of uplink propagation threshold, then the part descending sub frame determining to meet requirement from the current downlink transfer with terminal is as can by the flexible duplexing subframe of flexible dispatching; Generation can by the change indication information of the described flexible duplex subframe of flexible dispatching, and the direction modification information of the flexible duplex subframe in described change indication information is: the direction of the part descending sub frame of the described satisfied requirement determined is revised as upper row.
