The present disclosure provides a signal transmission method and a signal transmission apparatus. The signal transmission method includes steps of receiving, by a UE, a signal on a carrier or cell which uses a predetermined spectrum resource, and determining whether or not the received signal belongs to a serving carrier or serving cell of the UE; and in the case that the received signal belongs to the serving carrier or serving cell of the UE, performing measurement and/or data transmission by the UE in accordance with the received signal and/or a subsequently-received signal. According to the embodiments of the present disclosure, the UE determines whether or not the currently-received signal belongs to the serving carrier or cell of the UE, and in the case that the received signal belongs to the serving carrier or cell of the UE, perform the measurement and/r data transmission, so as to prevent the UE from receiving the erroneous data or performing the measurement and/or the data transmission based on the erroneous signal, thereby to prevent the system performance from being degraded and to utilize the predetermined spectrum resource appropriately. |
