Description

Method and device in wireless communication

Technical field

The present application relates to a transmission scheme of a wireless signal in a wireless communication system, and more particularly to a user equipment and a method and apparatus in a base station supporting low latency communication.

Background technique

In the existing LTE (Long-term Evolution) and LTE-A (Long Term Evolution Advanced) systems, TTI (Transmission Time Interval) or Subframe or PRB ( The Physical Resource Block (Ph) corresponds to one ms (milli-second) in time. An LTE subframe includes two time slots (Time Slots), which are a first time slot and a second time slot, respectively, and the first time slot and the second time slot respectively occupy the first half of a LTE subframe. And the last half a millisecond.

In the Latency Reduction (LR, Delay Reduction) topic of 3GPP (3rd Generation Partner Project) Release 14, an important application purpose is low-latency communication. In the traditional LTE system, the downlink PDSCH (Physical Downlink Shared Channel) transmission and the corresponding HARQ-ACK (Hybrid Automatic Repeat request Acknowledgment) are in strict strict predefined timing relationship. . In order to reduce the delay, the traditional LTE frame structure needs to be redesigned. Correspondingly, the uplink feedback for the new downlink transmission and downlink transmission also needs to be redesigned.

Summary of the invention

In the Release 9/10 system, the CA (Carrier Aggregation) of the aggregated carrier number is not more than 5, and the PUCCH (Physical Uplink Control Channel) Format 3 is introduced. The Format 3 based PUCCH can be transmitted at one time. The HARQ-ACK corresponding to the data transmission on the downlink CC (Component Carrier). In the Release 13 system, PUCCH Format 4&5 is introduced for CAs with aggregated carriers of no more than 32, and PUCCH based on Format 4&5 can be transmitted at one time. The HARQ-ACK corresponding to the data transmission on the 32 downlink CCs (component carriers) is transmitted.

In the Release 14 delay related related Study Item, one direction that needs to be studied is the design of the timing relationship of the uplink feedback for downlink transmission and downlink transmission. Compared with the LTE system, for the purpose of low delay transmission, the downlink The time interval between transmission and the corresponding uplink HARQ-ACK will be reduced. However, when the UE (User Equipment) can simultaneously support a 1 ms-based TTI (Transmission Time Interval) and multiple downlink transmissions based on an sTTI (Short Transmission Time Interval) of less than 1 ms. The uplink HARQ-ACK of the multiple downlink transmissions may be uploaded in the same subframe. At the same time, when the UE supports downlink aggregation (Carrier Aggregation), the situation will become more complicated, and more HARQ-ACKs will be uploaded to the base station in the same subframe.

An intuitive solution is to transmit UL (Uplink) HARQ-ACK based on 1 ms TTI in a traditional PUCCH or PUSCH (Physical Uplink Shared Channel), based on UL HARQ of sTTI less than 1 ms. - ACK is transmitted in a newly designed sPUCCH (Short Latency Physical Uplink Control Channel) or sPUSCH (Short Latency Physical Uplink Shared Channel). However, it is obvious that this method will increase the uplink power of the UE, which will affect the performance of the UE with power limitation. At the same time, because multiple UCIs (Uplink Control Information) are sent, the efficiency is also low.
