Abstract: The present invention provides an uplink control information transmitting method and apparatus. In the method, when a user equipment (UE) is configured with an uplink carrier in an unlicensed spectrum, the UE transmits uplink control information through a pre-defined location and a pre-defined format in a licensed spectrum and/or a pre-defined location and a pre-defined format in an idle unlicensed spectrum according to an uplink (UL) grant transmitted from a base station and the UCI to be transmitted. According to the technical solution provided by the present invention, the UCI is flexibly transmitted in the licensed spectrum or in the idle unlicensed spectrum, thereby improving transmission efficiency and reducing impact on downlink signal scheduling when the UE is configured with the uplink carrier in the unlicensed spectrum and transmits the UCI, and further improving LTE network efficiency.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a power allocating method. A User Equipment (UE) receives power control indication information from a control node, obtains a power control mode, and/or, uplink transmission power configuration information. The UE allocates power for each uplink carrier, based on the power control mode, and/or, the uplink transmission power configuration information. By applying the present disclosure, power waste generated in the following scene may be reduced. A scheduled uplink signal cannot be transmitted in a corresponding carrier due to a busy channel.
