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 communication method, apparatus, and system. The communication method includes: a centralized unit receives a data packet sent in a multicast manner. The centralized unit generates a PDCP data unit based on the data packet, where the PDCP data unit includes the data packet and a PDCP header. The centralized unit sends the PDCP data unit to a distributed unit. The distributed unit receives the PDCP data unit from the centralized unit, where the PDCP data unit includes the PDCP header, a synchronization protocol header, and a payload. The distributed unit generates a MAC data unit, where the MAC data unit includes a MAC header, an RLC header, the PDCP header, and the payload.

Abstract: This application provides a positioning method and a communication apparatus. When reporting, to a network device, measurement information of a plurality of paths that is obtained through positioning measurement, a terminal device associates each path with a positioning reference signal PRS resource identifier or related information of a beam (for example, an angle of a transmit beam or a direction of the transmit beam) corresponding to the PRS resource identifier. While learning of the measurement information of each path, the network device can further learn of information about a beam corresponding to the path. This helps the network device improve positioning accuracy.
