Abstract: Embodiments of this disclosure relate to the communication field, and provide a data transmission method for short-range wireless communication, and a communication apparatus. The method includes: A first device sends a plurality of first data packets to a second device, where the first device and the second device perform short-range wireless communication. The first device receives a second data packet from the second device, where a first field in the second data packet includes a plurality of indications indicating whether the plurality of first data packets are successfully received. In this manner, when the first device using short-range wireless communication performs data transmission with the second device, the second device respectively indicates, by using the plurality of indications in the second data packet, whether the plurality of first data packets are successfully received, which can avoid frequent switching between sending and receiving, reduce a duration of short-range wireless communication, and improve communication efficiency.

Abstract: A clock synchronization method includes sending a narrowband synchronization frame via a narrowband system, to complete coarse clock synchronization in a wideband system; and sending a wideband frame after duration, allocated by the narrowband system, for switching from a narrowband to a wideband ends, to complete fine clock synchronization in the wideband system.
