The invention discloses a kind of data transmission method of eNB side, its implementation specifically comprises following operation as shown in Figure 1:
Step 100, eNB determine that the PUSCH to the FDD up-link carrier dispatches and feeds back employed TDD uplink-downlink configuration.
The TDD uplink-downlink configuration that step 100 is determined is as shown in table 1.
Step 110, eNB are at the descending sub frame of TDD uplink-downlink configuration indication and/or the PUSCH on the special subframe scheduling FDD up-link carrier.
After the eNB side was carried out the PUSCH scheduling to UE, UE transmitted PUSCH according to the indication of scheduling at the FDD sub-frame of uplink.
Step 120, eNB receive above-mentioned PUSCH at the FDD sub-frame of uplink.
Step 130, eNB are fed back above-mentioned PUSCH on the descending sub frame of above-mentioned TDD uplink-downlink configuration indication and/or special subframe.
Among the present invention, descending sub frame and/or the special subframe that is used for the above-mentioned TDD uplink-downlink configuration that PUSCH feeds back is indicated can be called the feedback subframe.Wherein, if in the feedback subframe PHICH resource is arranged, then carry out PUSCH HARQ feedback, if do not have the PHICH resource in the feedback subframe, the uplink scheduling signaling that then transmission retransmits in this feedback subframe.PUSCH HARQ feedback refers to feeding back ACK/NACK (correct/error) information.
In the embodiment of the invention, the descending sub frame that the PUSCH of FDD up-link carrier is dispatched can be the FDD descending sub frame, also can be the TDD descending sub frame.The descending sub frame that the PUSCH of FDD up-link carrier is fed back can be the FDD descending sub frame, also can be the TDD descending sub frame.
For above-mentioned steps 130, the invention provides following four kinds of preferred implementations:
(1)
If it is identical with the sub-frame of uplink numbering of above-mentioned TDD uplink-downlink configuration indication to transmit the numbering of FDD sub-frame of uplink of above-mentioned PUSCH, feed back according to the feedback sequential of PUSCH HARQ corresponding to this TDD uplink-downlink configuration;
