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 and safety services. A method of a terminal in a communication system comprises transmitting, to a base station, an uplink transmission subset restriction (UL-TxSR) request, based on a predetermined condition related to uplink transmission power; receiving, from the base station, a response corresponding to the UL-TxSR request; and transmitting, to the base station, an uplink signal based on the UL-TxSR.

Abstract: Disclosed are a communication scheme and a system thereof for converging an IoT technology and a 5G communication system for supporting a high data transmission rate beyond that of a 4G system. The disclosure can be applied to intelligent services (for example, services related to a smart home, smart building, smart city, smart car, connected car, health care, digital education, retail business, security, and safety) based on the 5G communication technology and the IoT-related technology. A method of receiving a synchronization signal block (SSB) by a UE in a wireless communication system may include: identifying whether a bandwidth of a cell transmitting an SSB which the UE desires to receive corresponds to a first frequency band (FR); when the bandwidth of the cell corresponds to the first frequency band, receiving the SSB using a single carrier waveform; and acquiring synchronization, based on the received SSB; and acquiring system information.
