Patent ID: 11109383

Abstract:
A method according to an embodiment of the present invention, in which a terminal receives downlink control information from a base station in a wireless communication system comprises: a step of receiving information on an antenna port from the base station; a step of performing blind detection of a control channel on the basis of the information on the antenna port; and a step of obtaining downlink control information carried by the control channel through the blind detection, wherein it can be assumed that the information on the antenna port indicates the at least one antenna port to be monitored by the terminal among the plurality of antenna ports used by the base station for the control channel transmission, and the terminal while performing the blind detection applies a specific transmission diversity scheme to at least one antenna port indicated through the information on the antenna port. The terminal is capable of communicating with at least one of another terminal, a terminal related to an autonomous driving vehicle, the base station or a network.
