Abstract: The present disclosure discloses example communications methods and apparatuses. One example method includes obtaining effective carrier indication information from a network device. An effective carrier frequency is obtained based on the effective carrier indication information, where the effective carrier indication information includes first information, second information, and third information. The first information includes first indication information, second indication information, or third indication information. The first indication information is used to indicate that carriers are not paired, the second indication information is used to indicate that carriers are paired, the third indication information is used to indicate a paired carrier frequency spacing, the second information is used to indicate a start carrier frequency, and the third information is used to indicate a frequency domain location of an effective carrier relative to a start carrier.

Abstract: This application provides a communication method, a communications device, and a network device. When a beam failure occurs in a secondary cell of the communications device, the communications device sends a beam failure recovery request to the network device by using a PUCCH or a MAC CE, and determines an active state time of DRX based on a status of the beam failure recovery request. The communications device may also determine a stopping time of an uplink retransmission timer based on a running status of a configured grant timer, where the DRX of the communications device is in an active state when the uplink retransmission timer works; and monitors a PDCCH when the DRX of the communications device is in the active state.

Abstract: This present disclosure discloses example communication methods and communications apparatuses. One example communication method includes a terminal device determining a first offset of a first power class and a second offset of the first power class when a power class of the terminal device is the first power class. A compensation amount of the first power class is determined based on the first offset and the second offset. A determination as to whether to camp on a first cell is made based on the second offset and the compensation amount of the first power class.
