    Abstract: Embodiments provide a power adjustment method and an access network device, and the embodiments relate to the field of communication technologies. A target power increase value is adaptively determined based on a target key characteristic of a target cell, so that a cell coverage loss and a cell capacity loss caused by channel shutdown are compensated for, and a good energy-saving effect is obtained. The access network device blocks transmit channels that are of some of a plurality of antennas and that correspond to the target cell. Then, the access network device obtains the target key characteristic of the target cell, and determines the target power increase value based on the target key characteristic. The access network device increases, based on the target power increase value, transmit power of the access network device corresponding to the target cell or a target user.

    Abstract: A data transmission method is provided to resolve a problem of data transmission delay in a DRX mechanism. A RAN device sends, to a terminal in a DRX active period, first grant information that is used to perform initial transmission grant for first data. The RAN device sends, to the terminal in a retransmission active time in which the terminal expects to receive a retransmission grant for the first data, second grant information that is used to perform initial transmission grant for second data. Then the RAN device and the terminal remain in an active state in an activation extension time that is after sending of the second grant information.

    Abstract: This application provides a communication method and apparatus. The method may include: A cell in a first frequency range determines to enter an energy saving state. A terminal device accesses a cell in a second frequency range through cell selection. When the terminal device needs to enter the cell in the first frequency range, the cell in the second frequency range assists the terminal device in accessing the cell in the first frequency range. In this application, energy saving can be implemented through assistance between a plurality of cells. For example, the cell in the first frequency range may enter the energy saving state. Communication performance can be ensured. For example, the cell in the second frequency range may assist the terminal device in accessing the cell in the first frequency range in the energy saving state.

The RAN device sends, to the terminal in a retransmission active time in which the terminal expects to receive a retransmission grant for the first data, second grant information that is used to perform initial transmission grant for second data. Then the RAN device and the terminal remain in an active state in an activation extension time that is after sending of the second grant information. In this way, the RAN device may perform initial transmission by using a retransmission active time, so as to extend an active time.
