Carry out uplink.
7. system according to claim 6, which is characterized in that first power control unit includes:
Judgment module, for judging whether that power transient recurs M times on continuous N number of symbol according to power transient information；
Wherein, N, M are natural number more than or equal to 1 and N is greater than M；
First control module, for when power transient recurs M times on continuous N number of symbol, by the priority list
Judgement, which is thrown away, does not send the progress of the first symbol corresponding to the low physical channel of at least one loading priority or reference signal
Uplink；
Second control module, for when power transient recurs M times on continuous N number of symbol, by the priority list
The power for increasing or decreasing the second symbol corresponding to the low physical channel of at least one loading priority or reference signal carries out
Uplink；
Third control module, for when power transient does not recur M time on continuous N number of symbol, then continuation is by carrying
Physical channel or the symbol of reference signal continue the corresponding power that sends and carry out uplink.
8. system according to claim 7, which is characterized in that second control module includes:
Power increases submodule, is lower than adjacent priority for working as the corresponding power that sends of the lower symbol of priority on continuous symbol
When higher symbol corresponds to transmission power, then increase the corresponding transmission power of the lower symbol of priority；
Power reduces submodule, is higher than adjacent priority for working as the corresponding power that sends of the lower symbol of priority on continuous symbol
When higher symbol corresponds to transmission power, then the corresponding transmission power of the lower symbol of priority is reduced.
9. system according to claim 6, which is characterized in that the system also includes:
Second power control unit obtains the generation power wink on two continuous time slots by the judgement of power transient information for working as
Become, and when the channel demodulated reference signal of the first symbols carry Physical Uplink Shared Channel of the latter time slot, then judgement obtains
When carrying transmission power corresponding to the last symbol of physical channel or reference signal in previous time slot higher than the latter
After the first symbol for carrying the channel demodulated reference signal of Physical Uplink Shared Channel in gap, increase the shared letter of carrying physical uplink
The corresponding transmission power of the symbol of the channel demodulated reference signal in road is allowed to and carries physical channel or reference in previous time slot
Transmission power corresponding to the last symbol of signal is equal and carries out uplink.
