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. The present disclosure provides a power adjusting method and corresponding to control node and UE. According to the present disclosure, interference to adjacent devices of the same or different wireless access techniques may be avoided, uplink scheduling efficiency of the UE may be increased, and therefore the efficiency of the whole network is increased.

Abstract: An apparatus and a method for transmitting/receiving a Physical Uplink Shared CHannel (PUSCH) signal in a cellular radio communication system supporting a Carrier Aggregation (CA) scheme are provided. In the PUSCH transmission method, a User Equipment (UE) transmits a PUSCH signal to a Base Station (BS) based on an UpLink (UL)/DownLink (DL) Configuration, wherein, for a Time Division Duplexing (TDD) scheme, if the UE is configured with more than one serving cell, UL/DL Configurations of at least two serving cells are different, and a serving cell is one of a primary cell and a secondary cell, a UL/DL Configuration for the serving cell is set as a UL-reference UL/DL Configuration based on a pair formed by a UL/DL Configuration for another serving cell and the UL/DL Configuration for the serving cell.

Abstract translation: 提供了一种用于在支持载波聚合（CA）方案的蜂窝无线电通信系统中发送/接收物理上行链路共享信道（PUSCH）信号的装置和方法。 在PUSCH传输方法中，用户设备（UE）基于上行链路（UL）/下行链路（DL）配置向基站（BS）发送PUSCH信号，其中，对于时分双工（TDD）方案，如果 UE配置有多个服务小区，至少两个服务小区的UL / DL配置不同，并且服务小区是主小区和辅助小区之一，设置用于服务小区的UL / DL配置 作为基于由另一个服务小区的UL / DL配置形成的对和用于服务小区的UL / DL配置的UL参考UL / DL配置。
