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. Subsequently, uplink scheduling efficiency of the UE may be improved, and the whole network efficiency may also be enhanced.

Abstract: The provided is a method for transmitting HARQ-ACK in a LTE system, which is applicable to a situation that an uplink subframe is occupied in an FDD or TDD system. The method is implemented as follows. A UE receives information from an eNB, and determines the assignment of uplink subframes in a cell. The UE determines the transmission of HARQ-ACK according to the assignment of uplink subframes in the cell. By the provided method, the transmission of HARQ-ACK of PDSCH is less influenced when an uplink subframe in the FDD or TDD system is occupied.

Abstract: The present invention discloses a method for reporting channel state information, comprising the following steps of: acquiring, by UE, information about at least two sets of CSI RSs, wherein the information about CSI RSs comprises time domain resource and frequency domain resource occupied by CSI RSs; and measuring, by the UE, a reference signal according to the information about at least two sets of CSI RSs, determining channel state information, and reporting the channel state information to a base station. Another aspect of the present invention further provides a device for reporting channel state information. By the technical solutions provided by the present invention, after pre-coding the CSI RSs, the system performance can be improved, and the resources occupied by the CSI RSs may be greatly saved in practical applications, so that more downlink physical resources may be used for transmission of physical downlink shared channels (PDSCH), thereby increasing the throughput of downlink traffic.
