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: Examples of the present invention provide a method for allocating Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) channel resources supporting transmit diversity and channel selection. The method includes: receiving, by a UE, Physical Downlink Control Channel (PDCCH) information and Physical Downlink Shared Channel (PDSCH) data from a base station through two Carrier Components (CCs); obtaining, by the UE according to specific indication information, Physical Uplink Control Channel (PUCCH) channel resources required for transmitting HARQ-ACK feedback information using a transmit diversity technique; and transmitting, by the UE, the HARQ-ACK feedback information on the obtained PUCCH channel resources adopting the transmit diversity technique. According to the method provided by the examples of the present invention, it is possible to allocate HARQ-ACK channel resources to the UE reasonably and avoid waste of channel resources in the premise that channel selection and SORTD technique are supported.
