When TD-SCDMA system adopts the lower ascending time slot proportioning of 4:2, LTE-TDD system must adopt the lower up proportioning of 3:1, and special subframe must adopt the proportioning 0 shown in table two or proportioning 5, and the uplink/downlink frames that could realize two systems is synchronous.But proportioning 0 or proportioning 5 Zhong， GP districts have taken 9 or 10 symbols, have wasted system resource.If LTE-TDD system adopts proportioning 6, be that the proportioning of DwPTS, GP and UpPTS is while being 9:3:2, as shown in the arrow A in Fig. 2 C, exist TD-SCDMA system in uplink receiving state, and the situation of LTE-TDD system in descending transmission state, the uplink/downlink frames of two systems is not synchronous, the interference between unavoidably generation system thus.
In embodiments of the present invention, as shown in Fig. 3 A and 3B, when TD-SCDMA system adopts the lower ascending time slot proportioning of 4:2, by ascending pilot channel, move (UpShifting) technology, the ascending pilot channel UpPCH of the first radio frames of TD-SCDMA system is configured in the ascending time slot except uplink pilot time slot UpPTS, be that uplink pilot time slot UpPTS does not carry UpPCH channel, and UpPCH is configured on other ascending resource; Can be so that the second radio frames of LTE-TDD system adopt descending time slot and the ascending time slot proportioning of 3:1, and the descending pilot frequency time slot DwPTS of this second radio frames, to protect the proportioning of time slot GP and uplink pilot time slot UpPTS can be 9:4:1 or 9:3:2.
Particularly, as shown in the arrow A in Fig. 3 A and 3B, because the UpPCH of the first radio frames of TD-SCDMA system is configured in the ascending time slot except UpPTS, the UpPTS of this first radio frames does not carry UpPCH channel, do not exist a system in uplink receiving state, and the situation of another system in descending transmission state, the uplink/downlink frames of TD-SCDMA system and LTE-TDD system is synchronous, can avoid the interference between system thus.
In the technical scheme of the embodiment of the present invention, due to the second radio frames of LTE-TDD system, adopting proportioning is the special subframe of 9:4:1 or 9:3:2, each radio frames or field can be saved 6 OFDM symbols, for the carrier wave of 20MHz, the running time-frequency resource that each community can be saved is as shown in following equation (1); For the carrier wave of the 1.6MHz of TD-SCDMA system, the corresponding running time-frequency resource of UpPTS of each logic district waste is as shown in following equation (2).
