Abstract
The present disclosure relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure may be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or connected car, health care, digital education, retail business, a security and safety-related service, etc.) on the basis of 5G communication technology and IoT-related technology. The present disclosure discloses a method and device for transmitting uplink data.
Claims14
A method for a terminal supporting carrier aggregation (CA) of a first component carrier (CC) and a second CC in an unlicensed band to transmit an uplink signal, the method comprising:
- reporting, to a base station, a terminal capability for a phase discontinuity impact;
- receiving, from the base station, information for a configured grant PUSCH at the first CC;
- receiving, from the base station, information for a dynamic grant PUSCH at the second CC;
- determining to cancel a transmission of at least part of the configured grant PUSCH,
- wherein the transmission of the at least part of the configured grant PUSCH is cancelled from a time point;
- determining whether to cancel a transmission of at least part of the dynamic grant PUSCH;
- and
- transmitting, to the base station, the dynamic grant PUSCH,
- wherein the transmission of at least part of the dynamic grant PUSCH is cancelled from the time point in case that the first CC and the second CC are adjacent in frequency domain and the time point is located during transmission of the dynamic grant PUSCH.
A method for a base station performing carrier aggregation (CA) of a first component carrier (CC) and a second CC in an unlicensed band to receive an uplink signal, the method comprising:
- receiving, from a terminal, a report on a terminal capability for a phase discontinuity impact;
- transmitting, to the terminal, information for a configured grant PUSCH at the first CC;
- transmitting, to the terminal, information for a dynamic grant PUSCH at the second CC;
- and
- receiving, from the terminal, the dynamic grant PUSCH,
- wherein a transmission of at least part of the configured grant PUSCH is cancelled from a time point, and
- wherein the transmission of at least part of the dynamic grant PUSCH is cancelled from the time point, in case that the first CC and the second CC are adjacent in frequency domain and the time point is located during transmission of the dynamic grant.
A terminal for supporting carrier aggregation (CA) of a first component carrier (CC) and a second CC in an unlicensed band, the terminal comprising:
- a transceiver;
- and
- a controller configured to control to:
- report, to a base station, a terminal capability for a phase discontinuity impact,
- receive, from the base station, information for a configured grant PUSCH at the first CC;
- receive, from the base station, information for a dynamic grant PUSCH at the second CC;
- determine to cancel a transmission of at least part of the configured grant PUSCH, wherein the transmission of the at least part of the configured grant PUSCH is cancelled from a time point;
- determine whether to cancel a transmission of at least part of the dynamic grant PUSCH;
- transmit, to the base station, the dynamic grant PUSCH,
- wherein the transmission of at least part of the dynamic grant PUSCH is cancelled from the time point, in case that the first CC and the second CC are adjacent in frequency domain and the time point is located during transmission of the dynamic grant PUSCH.
A base station for performing carrier aggregation (CA) of a first component carrier (CC) and a second CC in an unlicensed band, the base station comprising:
- a transceiver;
- and
- a controller configured to control to:
- receive a report on a terminal capability for a phase discontinuity impact from a terminal,
- transmit, to the terminal, information for a configured grant PUSCH at the first CC;
- transmit, to the terminal, information for a dynamic grant PUSCH at the second CC;
- receive, from the terminal, the dynamic grant PUSCH,
- wherein a transmission of at least part of the configured grant PUSCH is cancelled from a time point, and
- wherein the transmission of at least part of the dynamic grant PUSCH is cancelled from the time point, in case that the first CC and the second CC are adjacent in frequency domain and the time point is located during transmission of the dynamic grant PUSCH.
