User and base station in method and apparatus.
Background technology
Existing LTE (Long-term Evolution, Long Term Evolution) and LTE-A (Long Term Evolution
Advanced, the Long Term Evolution of enhancing) in system, TTI (Transmission Time Interval, Transmission Time Interval) or
Person's subframe (Subframe) or PRB (Physical Resource Block, Physical Resource Block) are right in time to (Pair)
Answer a ms (milli-second, millisecond).One LTE subframe includes two time slots (Time Slot), is the first time slot respectively
With the second time slot, and first time slot and second time slot take first half millisecond of a LTE subframe and later half respectively
Individual millisecond.
In 3GPP (3rd Generation Partner Project, third generation cooperative partner program) Release 14
In Latency Reduction (LR, delay reduce) problem, an important application purpose is exactly low latency communication.Traditional
In LTE system, the transmission of descending PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel)
And (Hybrid Automatic Repeat request Acknowledgment, mixing are automatic by corresponding HARQ-ACK
Repeat requests confirm) meet strict predefined sequential relationship.Demand for reducing delay, traditional LTE frame structures need
It is redesigned, corresponding, the uplink feedback that new downlink transfer and downlink transfer is directed to is also required to be redesigned.
The content of the invention
In the systems of Release 9/10,5 CA (Carrier Aggregation, carrier wave are not more than for polymerization carrier number
Polymerization), PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) Format 3 is introduced into,
PUCCH based on Format 3 can be transmitted once on CC descending no more than 5 (Component Carrier, forming carrier wave)
Data transfer corresponding to HARQ-ACK.In the systems of Release 13,32 CA, PUCCH are not more than for polymerization carrier number
