The present application provides a method and apparatus for receiving paging information, the method comprises: receiving paging indication information; determining whether one or more paging occasions have paging information required to be received by this UE, based on the paging indication information; receiving this paging information, when it is determined that one or more POs have paging information required to be received by this UE; ignoring this paging information, when it is determined that one or more POs do not have paging information required to be received by this UE. By doing this, a great number of work such as receiving, decoding and recognizing the paging information required to be received for other UEs is saved; reasonably configuring paging indication information can enable that the overhead for the processing work such as receiving paging indication information by the UE is far less than a great amount of overhead for processing the paging information for other UEs; thereby the efficiency for receiving the paging information is promoted, the system resources of the UE is saved, the power consumption of the UE is saved, and the duration of the UE is prolonged.

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.
