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: An apparatus and method for feeding back hybrid automatic repeat request-acknowledgement (HARQ-ACK) information are provided. The apparatus and method include user equipment (UE) that first receives a downlink grant (DL-GRANT) which schedules downlink HARQ transmission in a time-frequency bundling window corresponding to an uplink subframe used for feeding back HARQ-ACK, obtains a DL downlink assignment index (DL DAI) in the DL-GRANT, and determines a mapping value of each DL DAI. Then, according to the mapping value of the corresponding DL DAI, the HARQ-ACK bit of each HARQ feedback unit is mapped to a corresponding bit of a feedback bit sequence. According to the method and apparatus provided by the present disclosure, useless HARQ-ACK bits may be effectively removed, and efficiency for feeding back HARQ-ACK may be increased. As such, a downlink peak rate of a UE is ensured.

Abstract: A method and an apparatus are provided for transmitting a hybrid automatic repeat request-acknowledgment/negative acknowledgment (HARQ-ACK/NACK). A first set including at least one HARQ-ACK/NACK timing value is identified. Each timing value indicates a time difference between a downlink time unit for physical downlink shared channel (PDSCH) reception and an uplink time unit in which a HARQ-ACK/NACK feedback is transmitted. A second set is determined that includes at least one downlink time unit. A codebook is generated for the HARQ-ACK/NACK feedback. A size of the codebook is identified based on a size of the second set and a number of HARQ-ACK/NACK bits corresponding to each downlink time unit. The codebook is transmitted to the base station. The number of HARQ-ACK/NACK bits is determined based on a number of code block groups (CBGs) in one transmission block (TB), in case that scheduling for a downlink transmission is based on CBG.

Abstract: A method and an apparatus in a wireless communication system are provided. Configuration information is received on resource pools in multiple carriers for a vehicle to everything (V2X) sidelink communication. At least one carrier is selected for transmission among the multiple carriers. An order of the at least one carrier is determined according to a decreasing order based on a highest priority of a sidelink traffic channel. A set of candidate resources associated with each of the at least one carrier is determined according to the determined order. A candidate resource is excluded from the set of candidate resources, in case that the candidate resource is not supported due to a limitation of a user equipment (UE) in supported carrier combinations.
