Description

User equipment, method and device in base station used for low delay communication

Technical field

The present application relates to a transmission scheme for wireless signals in a wireless communication system, and more particularly to a method and apparatus for use in user equipment and base stations for 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 traditional LTE system, when the CA (Carrier Aggregation) mechanism is introduced, the related strategy of Power Scaling is defined to ensure the correct reception of UCI (Uplink Control Information) on the base station side. The specific method is: when multiple carriers are simultaneously transmitted at the same time, the carrier that transmits the PUCCH (Physical Uplink Control Channel) has a higher power priority than the PUSCH (Physical Uplink Shared Channel). The carrier of the carrier; and the carrier transmitting the PUSCH including the UCI has a higher priority in power allocation than the carrier transmitting the PUSCH not including the UCI.

3GPP (3rd Generation Partner Project), Reduced Latency in Release 14, and a new generation of Radio Access Technologies (NR), an important application scenario is URLLC ( Ultra-Reliable and Low Latency Communications, ultra-reliable and low-latency communication). For the scenario of Reduced Latency and URLLC, a new time interval, sTTI (Short Transmission Time Interval) is introduced, and the corresponding traditional power calibration method needs to be redesigned.

Summary of the invention

The researchers found that when sTTIs of different durations are used for uplink transmission on multiple carriers, data transmission of one long sTTI may be for transmission of multiple short sTTIs, and some of the short sTTI transmissions are uplink control channels. Some are data channels containing uplink control information, while others are pure uplink data channels, and this different channel combination may be dynamically changing. Therefore, the conventional power scaling method, the power selection used for the transmission of the long sTTI becomes a problem.

In an intuitive way, both carriers share the maximum transmit power that the UE can support. However, one of the most direct problems of this method is to reduce the transmission power of the uplink control channel, thereby affecting the performance of the uplink control channel.

In response to the above problems, the present application provides a solution. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments of the present application may be combined with each other arbitrarily. For example, features in embodiments and embodiments in the UE of the present application may be applied to a base station, and vice versa.

The first time interval is one of the R time intervals.

In the traditional LTE and LTE-A systems, the power calibration is performed based on each SF (Subframe), and on different carriers, the UE transmits only one physical channel in one subframe. When the UE supports sTTI and CA at the same time, and the configurations of the sTTIs are different on each carrier, the UE may transmit different uplink channels on different sTTIs in one subframe, and one long sTTI in one carrier will correspond.
