Abstract: This application provides a communication method and apparatus. A terminal may obtain configuration information of a wake-up signal of a camped cell and configuration information of a wake-up signal of another cell from a network device, to receive the wake-up signal of the camped cell and/or the wake-up signal of the another cell based on a signal measurement requirement of the terminal. In this way, power consumption of the terminal is reduced, and a signal of the camped cell and/or a signal of the another cell are/is measured. This can avoid a case that a main radio frequently wakes up to measure cell quality, to reduce energy consumption of the terminal.

Abstract: A multicast broadcast service sending method includes receiving indication information from a core network device. The indication information indicates that a receiver of a target multicast broadcast service includes a narrowband terminal and a broadband terminal. The method also includes sending a multicast control channel (MCCH) to the narrowband terminal and the broadband terminal. The MCCH is used to carry configuration information of a multicast traffic channel (MTCH) of the target multicast broadcast service, and a first frequency domain resource corresponding to the MCCH or a scheduling bandwidth occupied by the MCCH does not exceed a maximum bandwidth capability of the narrowband terminal. The method further includes sending the target multicast broadcast service to the narrowband terminal and the broadband terminal on a frequency domain resource corresponding to the MTCH.

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.

Abstract: This application provides a paging method, a communication apparatus, and a system. In the method, a terminal device sends first information to a first network device, where the first information includes a signal coverage level of the terminal device and whether the terminal device has a capability of receiving a first signal. The terminal device receives second information from the first network device, where the second information indicates the terminal device to receive the first signal or a second signal, the first signal is used to page or wake up the terminal device. Based on a specific application scenario, the terminal device may receive a signal with lower power consumption during demodulation from a network device, to reduce power consumption of the terminal device.

Abstract: A resource configuration method and an apparatus are provided. A serial number NBWPstart of a common resource block (CRB) corresponding to a start resource block (RB) of a bandwidth part (BWP) configured by a network device for a terminal device and a quantity LRBs of consecutive RBs occupied by the BWP meet one or more of the following conditions: NBWPstart mod K=0; and/or (NBWPstart+LRBs)mod K=0, where mod is a remainder operation, and K is a positive integer. Based on the foregoing method, during BWP configuration, it can be ensured that the serial number of the start CRB of the BWP and/or a serial number of a CRB corresponding to a last RB included in the BWP each are/is an integer multiple of K. In this way, it can be ensured that more RBs can be used in a control-resource set (CORESET), thereby increasing resource utilization.
