Title:
RADIO SIGNAL SENDING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/156084
Kind Code:
A1
Abstract:
A radio signal sending method and device, being applied to the fields of wireless communications and autonomous driving/intelligent driving, and in particular, relating to the processing of interference between cooperative radars. Said method comprises: a radar acquiring configuration information, the configuration information being used to indicate the ratio of the number of first data update periods to the number of second data update periods in one sending period, the first data update period being used to send a first radio signal, and the second data update period being used to send a second radio signal, the waveform configurations of the first radio signal and the second radio signal being different (S101); and according to the configuration information, transmitting, within at least one sending period for the radio signals, the first radio signal and the second radio signal (S102). The method effectively reduces mutual interference between the first and second radio signals. With regard to an on-board radar, interference between radars is reduced by means of time division multiplexing or frequency division multiplexing, etc., improving driving safety performance. The present invention further improves the capability of an autonomous driving or advanced driving assistant system (ADAS), and is applicable to Internet of vehicles, such as a vehicle-to-everything (V2X), long term evolution-vehicle (LTE-V), and a vehicle-to-vehicle (V2V), etc.
