摘要： The present invention provides a data transmission method, a terminal, and a RAN device to resolve a problem of data transmission delay in a DRX mechanism in the prior art. The method is: sending, by a RAN device to a terminal in a DRX active period, first grant information that is used to perform initial transmission grant for first data; sending, 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; and remaining, by the RAN device and the terminal, in an active state in an activation extension time that is after sending of the second grant information. The initial transmission grant may be uplink initial transmission grant or downlink initial transmission grant. In this way, the RAN device may perform initial transmission by using an uplink retransmission active time or a downlink retransmission active time, so as to extend an active time, which not only ensures use of a DRX technology, but also reduces impact of a delay.

摘要： Embodiments of this application provide a power adjustment method and an access network device, and relate to the field of communication technologies. A target power increase value can be 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. A specific solution is as follows: 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. Embodiments of this application are used in a power adjustment process.

摘要： Embodiments of the present invention provide a communication method, a network device, and a terminal device. The method includes: obtaining, by a network device, state information of current communication with a terminal device; determining, by the network device, a transmission time sequence of the terminal device based on the state information, where the transmission time sequence of the terminal device indicates duration from a time point at which the terminal device receives data to a time point at which the terminal device sends a response to the data; and sending, by the network device to the terminal device, indication information used to indicate the transmission time sequence. In the embodiments of the present invention, the network device can flexibly determine the transmission time sequence of the terminal device based on the state information of the communication with the terminal device, to avoid a prior-art problem caused by a single transmission time sequence, and improve system performance.
