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: This application provides a random access method and apparatus. The method includes: A terminal device determines a first random access preamble group from at least two random access preamble groups. The at least two random access preamble groups are associated with a sending manner of a message 3 in a random access procedure. The sending manner of the message 3 includes the following: The terminal device repeatedly sends the message 3, or the terminal device does not repeatedly send the message 3. At least one of the at least two random access preamble groups is associated with a sending manner in which the terminal device repeatedly sends the message 3. The terminal device determines a random access preamble from the first random access preamble group. The terminal device sends the random access preamble to a network device.

Abstract: Embodiments of this application provide a power determining method, an apparatus, and a system, to resolve a problem of how to determine transmit power of sending a plurality of random access preambles. The method includes: determining first transmit power of N random access preambles to be sent to a network device, where the first transmit power is related to a quantity N of the random access preambles, and N is an integer greater than 1; and sending the N random access preambles to the network device at the first transmit power. This application is applicable to the field of communication technologies.

Abstract: This application discloses a communication method and a communications apparatus. The method includes: determining, by a terminal device, transmission power for sending a random access preamble, where the transmission power is related to a random access preamble format and an offset based on the random access preamble format; and sending, by the terminal device, the random access preamble at the determined transmission power. The random access preamble format includes some or all of 0 to 3, A0 to A3, B1 to B4, C0, and C2. The corresponding apparatus is further disclosed. In this application, offsets corresponding to a plurality of random access preamble formats in a next-generation mobile communications system are provided, so that the transmission power of the random access preamble can be properly determined.

Abstract: This application discloses a communications method and apparatus. The method includes: sending, by a terminal device, a first message to a network device, where the first message includes a first random access preamble and first data, and a first redundancy version is used for the first data; and determining, by the terminal device, that the first data fails to be sent, and retransmitting the first data, where a second redundancy version is used for the first data. The corresponding communications apparatus is further disclosed. An incremental redundancy manner is used in a retransmission procedure of random access data.

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.
