Combination as follows: LTE is time slot configuration 1, and TD-SCDMA uplink and downlink timeslot proportioning is 3:3；When LTE is
Gap configuration 2, TD-SCDMA uplink and downlink timeslot proportioning is 2:4.
It addition, when downlink transfer, in order to avoid multipath effect causes intersymbol interference, at each OFDM
(Orthogonal Frequency Division Multiplexing, orthogonal frequency division multiplexi) is front all can be added
Upper CP (Cyclic Prefix, Cyclic Prefix), different according to the persistent period, CP can be divided into again conventional CP with
And extension CP.
For conventional CP, based on above-mentioned restrictive condition 2, LTE special subframe configuration under time slot configuration 1
Unrestricted, time slot configuration 2 times, the configuration of its special subframe is limited to 0 or 5.
For extension CP, based on above-mentioned restrictive condition 2, LTE special subframe configuration under time slot configuration 1
Unrestricted, time slot configuration 2 times, the configuration of its special subframe is limited to 0 or 4.
The symbolic number occupied due to the GP region of special subframe configuration 5 is 9, is considering PDCCH
The symbolic number that (physical downlink control channel, Physical Downlink Control Channel) takies is 3
In the case of, this special subframe cannot dispatching downlink business, under proportioning 2 downlink throughput capacity lose about 25%
Left and right.
