Abstract: A communication method includes receiving a first message from a first network device, and sending a second message to a terminal device. The first message includes random access related information. The second message indicates a first random access type that is usable in a random access procedure. The first random access type is a 2-step random access channel (RACH) or a 4-step RACH. The random access related information includes at least one of random access indication information useable to indicate the first random access type, random access capability information including information of a random access type supported by the terminal device, random access mode information useable to indicate a contention-based random access mode or contention-free random access mode in the random access procedure, an early downlink-data transmission indication useable to indicate to transmit a downlink data packet in the random access procedure, or a size of the downlink data packet.

Abstract: This application relates to a measurement method and an apparatus. If determining that a terminal device meets a first measurement reporting condition, the terminal device sends first information to a network device. After receiving the first information, the network device sends second information to the terminal device, and the terminal device receives the second information from the network device, where the second information is used to indicate to enter a relaxed measurement state of a serving cell. For such a terminal device, frequent measurement of the serving cell is equivalent to an unnecessary measurement process, and causes high power consumption. Therefore, the network device may indicate such a terminal device to enter the relaxed measurement state of the serving cell, to reduce a measurement process of the serving cell, so as to save power.

Abstract: This application provides a wireless communications method and apparatus, to implement good performance of communication between a terminal device and a network device. The wireless communication method includes: generating flight path information, where the flight path information includes location information of at least one target node on a flight path; and sending the flight path information. Therefore, a target network device can determine, based on flight path information reported by the terminal device, a flight path along which the terminal device is to fly, and the target network device may determine, based on the future flight path, at least one network device serving the terminal device. Based on this, a success rate of handover of the terminal device in a network is improved; in this way, good performance of communication between the terminal device and the network device is implemented.

Abstract: The application discloses a communication method, comprising: After a connection failure, a first user equipment sends a first indication message to a first network device through a communications interface (namely, a target interface) between terminal devices, so that the first network device proactively sends context information of the first user equipment to a second network device that serves a cell to which the first user equipment may be reconnected. In this way, when a connection failure occurs, the user equipment may instruct a source network device to push context information of the user equipment in advance, so that a network device serving the cell for reestablishment does not need to obtain the context information by sending a request for obtaining context information to the source network device during connection re-establishment. Therefore, a communication delay between network devices and signaling overheads on an X2 interface can be reduced to some extent.
