Abstract: This application discloses a signal sending method, a signal receiving method, and a communication apparatus. The method includes: A network device determines a first SSB and a second SSB, sends the first SSB in a first BWP, and sends the second SSB in a second BWP. Transmit power of the first SSB is different from transmit power of the second SSB. The first BWP may be considered as a BWP of a first-type terminal device, and the second BWP may be considered as a BWP of a second-type terminal device. The network device may send the first SSB in the first BWP, and send the second SSB in the second BWP. The second-type terminal device obtains an SSB from the network device without switching from the second BWP to the first BWP, to reduce a quantity of BWP switching times, so as to reduce power consumption.
