Abstract: The present disclosure provides a handover method for grant-free transmission, a terminal device, and a network device. The handover method includes: sending, by a first network device, a handover request message to a second network device to request to hand over a terminal device from the first network device to the second network device to perform grant-free transmission; receiving, by the first network device, a handover request acknowledgement message sent by the second network device to acknowledge handing over the terminal device from the first network device to the second network device to perform grant-free transmission; and sending, by the first network device, a handover instruction message to the terminal device to instruct the terminal device to transmit a signal to the second network device on a CTU resource in a grant-free transmission mode.

Abstract: Embodiments of the present invention disclose a data transmission method and a related device and system. A data transmission method includes: A transmitter performs scrambling, constellation modulation, and multiple-input multiple-output precoding processing sequentially on downlink user data to obtain a precoded symbol sequence; performs time-frequency resource mapping on the precoded symbol sequence to obtain frequency domain data of an OFDM symbol; performs conjugate symmetric extension and IFFT on the frequency domain data of the OFDM symbol to obtain a time domain real-number sequence; performs CP insertion processing on the time domain real-number sequence to form a first downlink time domain baseband signal; loads the first downlink time domain baseband signal onto a direct current of a LED lighting circuit to form a LED driving electrical signal; and converts the LED driving electrical signal into a visible beam of the LED for transmission.
