Information sending method, information receiving method and device thereof

Provided are an information sending method, an information receiving method and a device thereof, in order to solve the problem of how to send or receive a CSI-RS so as to reduce interference. The method comprises: a UE acquiring first configuration information about a common CSI-RS, the first configuration information being used for indicating the transmission of a first resource unit set of the common CSI-RS; the UE determining to transmit at least one first resource of a common channel, the first resource comprising the first resource unit set of the common CSI-RS; and the UE receiving the common channel over the first resource bypassing the first resource unit set. The device comprises a base station or a user equipment. The technical solution can avoid the interference of a common CSI-RS to a common channel, and by means of first configuration information about the common CSI-RS, can expand CSI-RS resources.
