Abstract
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.
Claims15
A method for transmitting power headroom information by a terminal in a wireless communication system, the method comprising:
- generating power headroom information for a serving cell based on whether first uplink scheduling information is received in or earlier than a first subframe on the serving cell, the first uplink scheduling information indicating a transmission in a second subframe;
- and
- transmitting, to a base station, the power headroom information in the second subframe.
A terminal for transmitting power headroom information in a wireless communication system, the terminal comprising:
- a transceiver configured to transmit and receive signals;
- and
- a controlled coupled with the transceiver and configured to generate power headroom information for a serving cell based on whether first uplink scheduling information is received in or earlier than a first subframe on the serving cell, the first uplink scheduling information indicating a transmission in a second subframe, and to transmit, to a base station, the power headroom information in the second subframe.
A method for receiving power headroom information by a base station in a wireless communication system, the method comprising:
- transmitting, to a terminal, first uplink scheduling information on a serving cell;
- transmitting, to the terminal, second uplink scheduling information on the serving cell;
- and
- receiving, from the terminal, power headroom information in a first subframe,
- wherein the power headroom information for the serving cell is generated based on whether the second uplink scheduling information is transmitted in or earlier than a second subframe on the serving cell, the second uplink scheduling information indicating a transmission in the first subframe on the serving cell.
A base station for receiving power headroom information in a wireless communication system, the base station comprising:
- a transceiver configured to transmit and receive signals;
- and
- a controller coupled with the transceiver and configured to transmit, to a terminal, first uplink scheduling information on a serving cell, to transmit, to the terminal, second uplink scheduling information on the serving cell, and to receive, from the terminal, power headroom information in a first subframe,
- wherein the power headroom information for the serving cell is generated based on whether the second uplink scheduling information is transmitted in or earlier than a second subframe on the serving cell, the second uplink scheduling information indicating a transmission in the first subframe on the serving cell.
