Abstract: Example signal sending methods and apparatus are described. One example method includes receiving a media access control (MAC) control element (CE) from a terminal device. The MAC CE indicates a power headroom in a first power headroom set or a power headroom in a second power headroom set. If the MAC CE indicates the power headroom in the first power headroom set, the power headroom in the first power headroom set is determined based on a second bit field comprised in the MAC CE, where the MAC CE includes a first bit field and the second bit field, and the first bit field is a reserved bit field. If the MAC CE indicates the power headroom in the second power headroom set, the power headroom in the second power headroom set is determined based on a third bit field comprised in the MAC CE, where the third bit field includes a bit of the first bit field and a bit of the second bit field.

Abstract: Example signal sending methods and apparatus are described. One example method includes generating a media access control (MAC) control element (CE) indicating a power headroom in a first power headroom set or a power headroom in a second power headroom set. If the MAC CE indicates the power headroom in the first power headroom set, the MAC CE includes a first bit field and a second bit field, where the first bit field is a reserved bit field, and the second bit field indicates the power headroom in the first power headroom set. If the MAC CE indicates the power headroom in the second power headroom set, the MAC CE includes a third bit field, where the third bit field is used to indicate the power headroom in the second power headroom set, and the third bit field includes a bit of the first bit field and a bit of the second bit field. The MAC CE is sent to a network device.

Abstract: Example communication methods and apparatus are described. One example method includes receiving a first parameter by a terminal device from a first device, where the first parameter corresponds to first wake-up signal (WUS) configuration information in at least one piece of WUS configuration information, and the first WUS configuration information includes information about a first WUS time-frequency resource. The terminal device determines the first WUS time-frequency resource based on the first parameter, and receives a first WUS from a second device on the first WUS time-frequency resource, where the first WUS is used to wake up the terminal device. In this method, the terminal device can determine the first WUS time-frequency resource based on the first parameter received from the first device, and then receive the first WUS from the second device on the first WUS time-frequency resource.

Abstract: This application provides a random access method and apparatus. The method may include determining, by a terminal, a service attribute of to-be-transmitted data, where the service attribute includes one or more of the following: a service type attribute, a service packet attribute, and a service latency attribute. The method may also include sending, by the terminal when the service attribute meets a preset condition for early data transmission, a random access request to a network device using a dedicated resource for the early data transmission. In this way, the early data transmission is initiated after the service attribute meets the preset condition for the early data transmission, so that a quantity of times for which the early data transmission is initiated is reduced, thereby saving resources. In addition, a success rate of the early data transmission can be improved.

Abstract: A multicast bearer management method includes: in a process of receiving service data of a single cell-multimedia broadcast multicast service traffic channel SC-MTCH, suspending a single cell-multimedia broadcast multicast service point to multipoint radio bearer SC-MRB corresponding to the SC-MTCH when there is a first type of data to be received; and when reception of the first type of data is completed, restoring or releasing the SC-MRB based on a temporary mobile group identity TMGI and/or a session identity corresponding to the SC-MRB. The technical solutions in the embodiments of the present invention can prevent frequent release and establishment of SC-MRBs, thereby saving network resources and power of a terminal device.
