Abstract: Embodiments of the present disclosure disclose a data transmission method and a communications device. The method in the embodiments of the present disclosure includes: obtaining, by a first communications device, a transmission mode instruction, where the transmission mode instruction is used to instruct to use a frequency-domain repetition mode to transmit data, and the frequency-domain repetition mode means that same data is repeatedly transmitted on different frequency-domain resources; determining, by the first communications device, the frequency-domain repetition mode based on the transmission mode instruction; and performing, by the first communications device, data transmission with a second communications device in the frequency-domain repetition mode.

Abstract: Example resource indication methods and apparatus are described. One example method includes determining a resource used by a terminal to send an uplink control signal by a base station. The base station sends indication information to the terminal, where the indication information is used to indicate the resource or a target parameter. The target parameter includes at least one of parameters used by the terminal to determine the resource. The described methods are applicable to the field of communications technologies.

Abstract: The present disclosure relates to methods, apparatus, and systems for a physical layer protocol data unit (PPDU) transmission. One example method includes generating a PPDU including a signal extension (SE) field arranged after a last orthogonal frequency division multiplexing (OFDM) symbol of a plurality of OFDM symbols, the PPDU including indication information in a high efficiency signaling field (HE-SIG), the indication information being generated based on a symbol length of the SE field and configured to indicate whether a receive end needs to adjust a calculated quantity of the plurality of OFDM symbols, and sending the PPDU to the receive end.

Abstract: A power control method and apparatus are provided. The method includes: determining, by a first station obtaining a transmission opportunity TXOP, status indication information after determining working statuses of M second stations during the TXOP, where the status indication information is used to instruct a second station in the M second stations that needs to receive data during the TXOP to remain in a listening state, and instruct a second station in the M second stations that does not need to receive data during the TXOP to enter a sleep state; and sending, by the first station, the status indication information.
