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 present disclosure provides a method for feeding back hybrid automatic repeat request-acknowledgement (HARQ-ACK) information. In the method provided by the present disclosure, an evolved Node B (eNB) transmits Downlink Assignment (DL-GRANT) within a time-frequency bundling window, which corresponds to an uplink subframe feeding back HARQ-ACK. A UE receives DL-GRANT scheduling downlink HARQ transmission in the time-frequency bundling window corresponding to respective uplink subframe for feeding back HARQ-ACK in turn, obtains a DL DAI in the DL-GRANT, and determines a mapping value of each DL DAI; then, maps HARQ-ACK bits of the time-frequency bundling window corresponding to respective uplink subframe for feeding back the HARQ-ACK to corresponding bits of a feedback bit sequence according to the mapping value of the DL DAI; and transmits the HARQ-ACK on an available uplink carrier. The present disclosure also provides a method for feeding back HARQ-ACK information. The UE transmits HARQ-ACK on an indicated carrier according to indication information of a base station. According to the method and apparatus provided by the present disclosure, efficiency for feeding back the HARQ-ACK can be increased and downlink peak rate of the UE can be ensured.

Methods and apparatuses for grid mapping are described. A method for operating a base station comprises configuring grid mapping patterns for a plurality of terminals, transmitting, to the plurality of terminals, the grid mapping patterns, receiving, from the plurality of terminals, information on which a grid mapping is performed based on the grid mapping patterns, and identifying data of the information corresponding to each of the plurality of terminals based on the grid mapping patterns. Therefore, the terminal can hold a low peak-to-average power ratio, and the power consumption can be effectively saved. The base station can complete signal detection in a moderate detection complexity by multi-terminal joint detection. The detection complexity and the performance are balanced.
