Another kind is feasible to be achieved in that: the network side equipment carries the TPC command word and SUL of FDD up-link carrier
The TPC command word of wave passes through different DCI 3/3A respectively and is sent to the terminal device.
If the multiple up-link carriers of terminal equipment configuration, for example, terminal device is configured with FDD up-link carrier and one simultaneously
A SUL carrier wave, then the Physical Uplink Shared Channel carried on FDD up-link carrier can be arranged in eNodeB in a DCI 3/3A
(Physical Uplink Shared Channel, abbreviation PUSCH) corresponding TPC command word, in another DCI 3/3A
The corresponding TPC command word of the PUSCH carried on SUL carrier wave is set, that is to say, that the corresponding TPC command word of FDD up-link carrier and
The corresponding TPC command word of SUL carrier wave is arranged in two different DCI 3/3A.In this way, realizing terminal equipment configuration
The mode in different DCI 3/3A is arranged in the corresponding TPC command word of multiple up-link carriers.ENodeB is further by one

In a DCI 3/3A.
Another is feasible to be achieved in that: the network side equipment will each uplink at least one described up-link carrier
The identification information of the corresponding TPC command word of carrier wave and each up-link carrier is sent to the terminal device.
If the multiple up-link carriers of terminal equipment configuration, for example, terminal device is configured with FDD up-link carrier and one simultaneously
