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.

Abstract: A message transmission method and a device are used to accelerate a random access procedure. The method includes: receiving, by a terminal device, a repetition quantity of an uplink message from a network device, in response to determining that a reference signal receive power (RSRP) range of the terminal device is within an RSRP range corresponding to a signal coverage enhancement level 0, wherein the uplink message comprises a third message of a sequence of messages comprised in a random access attempt; calculating, by the terminal device, transmit power based on a power control parameter for the repetition quantity; and sending, by the terminal device, the uplink message to the network device based on the calculated transmit power.

Abstract: Embodiments of this application provide a method for receiving and sending a reference signal, an apparatus, and a system, so that a network device can correctly demodulate uplink data of different terminal devices of a same cell. This solution is applicable to a wireless communications system including a first cell. The first cell includes a plurality of terminal devices that can transmit uplink data on a same time-frequency resource. A first terminal device in the plurality of terminal devices determines an index of a first sequence based on a first parameter value, and generates a first reference signal based on the first sequence indicated by the index of the first sequence. Then, the first terminal device sends the first reference signal to the network device. The first parameter value is different from a parameter value corresponding to another terminal device in the plurality of terminal devices.
