Abstract
The 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 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 or safety services.
Claims20
A method of transmitting an uplink signal by a terminal in a wireless communication system, the method comprising:
- receiving first information for a pathloss reference linking from a base station;
- receiving second information for at least one pathloss reference signal (RS) resource from the base station;
- and
- transmitting one of a physical uplink shared channel (PUSCH) transmission, a physical uplink control channel (PUCCH) transmission or a sounding reference signal (SRS) transmission on a first serving cell based on a first transmission power,
- wherein the first transmission power is identified based on a downlink pathloss, the downlink pathloss being calculated using a RS resource on an active downlink bandwidth path (BWP) of a serving cell indicated by the first information, and the RS resource is identified by the second information.
A method of receiving an uplink signal by a base station in a wireless communication system, the method comprising:
- transmitting first information for a pathloss reference linking to a terminal;
- transmitting second information for at least one pathloss reference signal (RS) resource to the terminal;
- and
- receiving one of a physical uplink shared channel (PUSCH) transmission, a physical uplink control channel (PUCCH) transmission or a sounding reference signal (SRS) transmission on a first serving cell based on a first transmission power,
- wherein the first transmission power is identified based on a downlink pathloss, the downlink pathloss being calculated using a RS resource on an active downlink bandwidth path (BWP) of a serving cell indicated by the first information, and the RS resource is identified by the second information.
A terminal for transmitting an uplink signal in a wireless communication system, the terminal comprising:
- a transceiver configured to transmit and receive a signal;
- and
- a controller configured to:
- receive first information for a pathloss reference linking from a base station,
- receive second information for at least one pathloss reference signal (RS) resource from the base station, and
- transmit one of a physical uplink shared channel (PUSCH) transmission, a physical uplink control channel (PUCCH) transmission or a sounding reference signal (SRS) transmission on a first serving cell based on a first transmission power,
- wherein the first transmission power is identified based on a downlink pathloss, the downlink pathloss being calculated using a RS resource on an active downlink bandwidth path (BWP) of a serving cell indicated by the first information, and the RS resource is identified by the second information.
A base station for receiving an uplink signal in a wireless communication system, the base station comprising:
- a transceiver configured to transmit and receive a signal;
- and
- a controller configured to:
- transmit first information for a pathloss reference linking to a terminal,
- transmit second information for at least one pathloss reference signal (RS) resource to the terminal, and
- receive one of a physical uplink shared channel (PUSCH) transmission, a physical uplink control channel (PUCCH) transmission or a sounding reference signal (SRS) transmission on a first serving cell based on a first transmission power,
- wherein the first transmission power is identified based on a downlink pathloss, the downlink pathloss being calculated using a RS resource on an active downlink bandwidth path (BWP) of a serving cell indicated by the first information, and the RS resource is identified by the second information.
