Abstract: This disclosure includes a data transmission method, a network device, a terminal device, and a base station. In the data transmission method, a target network device receives data sent by a target base station. The data is sent by a terminal device to the target base station, and the data includes identification information of the terminal device. When the target network device acknowledges, by using the identification information, that the terminal device has not been registered with the target network device, the target network device obtains user information of the terminal device. After the target network device obtains the user information of the terminal device, the target network device sends the data to a gateway. By using the data transmission method, the network device, the terminal device, and the base station disclosed in this patent application, the terminal device can still properly perform data transmission during movement.

Abstract: Embodiments provide a channel contention method and apparatus. The channel contention apparatus belongs to a basic service set (BSS). The BSS includes an access point (AP) and at least one first station (STA). Both the AP and the at least one first STA participate in channel contention. The apparatus is the AP or any first STA. The apparatus includes a sensing module configured to sense a channel. The apparatus also includes a contention module configured to contend for the channel. The AP centrally performs control and scheduling so that all of at least one network device in the BSS can transmit data using the channel.

Abstract: Embodiments of the present invention disclose a data transmission method and a terminal. The method includes: detecting, by a terminal in an idle state, whether a logical channel of a first path includes first to-be-transmitted data, and whether a logical channel of a second path includes second to-be-transmitted data; and if it is detected that the logical channel of the first path does not include the first to-be-transmitted data and a length of the second to-be-transmitted data is less than a preset second path transmission data threshold, selecting the second path to transmit the second to-be-transmitted data, where the second to-be-transmitted data includes discontinuously transmitted application data whose length is less than a preset threshold.

Abstract: Embodiments provide a signal transmission method and apparatus. The method includes: modulating, by using a phase-shift keying PSK scheme with rotation of a first angle, at least a part of pilot information carried in at least one signaling symbol in a signaling field of a data packet, to obtain modulated pilot information; and sending, to a receive end, a data packet that carries the modulated pilot information. A modulation scheme different from a conventional modulation scheme is used in the embodiments to modulate pilot information carried in a signaling symbol in a signaling field of a data packet, so that a data packet format corresponding to the modulation scheme can be effectively detected at a receive end.
