Abstract: Embodiments of this application provide a data sending method, a data receiving method, and a device. In the data sending method, a receive end device performs a DRX operation at a low frequency based on a DRX parameter; and receives, in a time indicated by the DRX parameter, first indication information sent by a transmit end device, where the first indication information is used to instruct the receive end device to prepare to receive data at a high frequency. In this process, the receive end device performs the DRX operation only at the low frequency, and starts beam tracking only after receiving the first indication information that instructs the receive end device to receive the data at the high frequency, to avoid unnecessary beam tracking and save power of the receive end device.

Abstract: This application discloses a network access method, a network device, and a terminal. The method includes: obtaining, by a network device, indication information, where the indication information is used to indicate whether the terminal supports air communication; and when the indication information indicates that the terminal supports the air communication, determining, by the network device, that the terminal is allowed to access a network in which the network device is located. In this application, a quantity of unmanned aerial vehicle terminals that access the network can be limited, reducing interference caused by the unmanned aerial vehicle terminals to another terminal in the same network as the unmanned aerial vehicle terminals, and improving communication quality of the another terminal.

Abstract: Embodiments of the present invention relate to communications technologies, and provide a data transmission method and an apparatus. The method includes: sending, by a base station, a grouping instruction to a target terminal, where the grouping instruction is used to group, in a preset grouping manner, terminals in a cell in which the target terminal is located into N groups, totally or partially different resources are allocated to terminals in different groups of the N groups, and a resource corresponding to an ith group of the N groups is used by a terminal in the ith group in uplink non-scheduled transmission; and receiving data that is sent by the target terminal using a target resource. In the solutions, terminals in a cell are grouped, and terminals in a same group contend for a resource allocated to the group. This mitigates resource collision when an uplink non-scheduled transmission solution is used.

Abstract: The present disclosure provides an uplink data packet transmission method. The method includes: determining, by a terminal device, a CP length of a first uplink data frame; if the terminal device is in a state of out of uplink synchronization with a base station and in an RRC connected state, or is in an RRC idle state, generating the first uplink data frame for an uplink data packet according to the CP length and sending the first uplink data frame to the base station. The CP length is greater than a CP length of an uplink data frame sent by a terminal device that is in a state of uplink synchronization and in an RRC connected state. Therefore, signaling procedures such as random access and uplink synchronization can be omitted, so that the terminal device can directly send the uplink data packet by performing signaling exchange once.
