Title:
INFORMATION SENDING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/012565
Kind Code:
A1
Abstract:
Disclosed are an information sending method and apparatus, which relate to the field of communications. The method comprises: a first terminal sending a first indication message to a second terminal, wherein the first indication message is used for instructing the second terminal to report first information; the second terminal reporting the first information to the first terminal according to the first indication message, wherein the first information is used for indicating channel state information on a channel resource; and the first terminal sending a second indication message to the second terminal, wherein the second indication message is used for indicating information of a first resource set, the first resource set is determined by the first terminal with reference to the first information, and resources in the first resource set are resources for sidelink communication. In this way, the resources for sidelink communication that are determined by the first terminal are more accurate, and the probability of a resource conflict occurring when devices in the present group perform sidelink communication is thus reduced. The method provided in the embodiments of the present application can be applied to communication systems such as V2X, LTE-V, V2V, the Internet of Vehicles, MTC, IoT, LTE-M, M2M and the Internet of Things.
