Title: DATA TRANSMISSION METHOD, SENDING-END DEVICE AND RECEIVING-END DEVICE.
Abstract:
A data transmission method, a sending-end device and a receiving-end device. The method is applicable to a wireless communication system comprising a plurality of wave beams. The method comprises: a sending-end device determining sending at least one transmission wave beam used by data and wave beam indication information to the receiving-end device; the sending-end device sending the wave beam indication information to the receiving-end device; the sending-end device performing data transmission using the at least one transmission wave beam; and by means of the wave beam indication information, the sending-end device instructing the receiving-end device to use a corresponding receiving wave beam to receive data transmitted by the sending-end device, so that the receiving-end device can select an appropriate receiving wave beam to receive data, thereby improving the signal-to-interference-and-noise ratio of the received signal.
