US 2019/0058980 A1 · V2X COMMUNICATION METHOD AND APPARATUS

Abstract

Embodiments of the present disclosure provide a V2X communication method and apparatus. The method is applicable for a V2X node and includes: detecting a downlink control channel whose CRC code is scrambled by a V-RNTI relevant to the V2X node; and receiving V2X data information on a corresponding downlink data channel according to an indication of the detected downlink control channel. In the present disclosure, the receiving V2X node is able to receive V2X data information selectively, which avoids useless data receiving and data processing operations of the receiving V2X node, reduces the number of downlink control channels and downlink data channels to be detected and processed by the receiving V2X node.
