Abstract: This application discloses a communications method and apparatus. The method includes: obtaining, by a terminal device, downlink synchronization signal block index information; receiving, by the terminal device, information used to indicate an association relationship between a random access resource RO and a synchronization signal block; and accessing, by the terminal device, a network device based on the information on an RO corresponding to the synchronization signal block index information. This application further discloses a corresponding apparatus. A time-frequency location of a random access resource associated with each downlink synchronization signal is indicated, so that the terminal device obtains, through downlink synchronization, a time-frequency location for sending an uplink random access signal, to avoid a blind attempt of the terminal device and a beam mismatch of the network device occurring when the network device receives a random access signal, thereby improving efficiency.

Abstract: This application provides a random access method, a terminal, and a network device. The random access method includes: determining, by a terminal, whether a resource used for random access conflicts with a resource used for receiving a downlink signal; and if the resource used for the random access conflicts with the resource used for the downlink signal, preferentially using the conflicting random access resource for receiving the downlink signal but not for the random access. This avoids a conflict between receiving of the downlink signal and sending of an uplink random access preamble.

Abstract: The present disclosure relates to communication methods. One example method includes within a first discontinuous reception (DRX) cycle, starting, by a terminal device, a first timer (for example, a DRX inactivity timer (drx-InactivityTimer)) when a physical downlink control channel (PDCCH) indicates a new transmission. When the first timer expires at or after a time position for sending an indication signal, the terminal device does not receive the indication signal, where the time position is configured by a network device for the terminal device, and the indication signal is used to indicate the terminal device to sleep.

Abstract: A terminal device first authenticates whether the terminal device has permission to sense a to-be-measured object. If the terminal device has sensing permission, the terminal device senses the to-be-measured object. If the terminal device has no sensing permission, the terminal device does not sense the to-be-measured object. In this way, privacy leakage of the to-be-measured object is prevented.
