Abstract: A communication method and apparatus. A terminal device determines, based on first information received from a first network device, that a second network device has first time information, where the first time information is time information having precision that is higher than precision of second time information of the first network device. The terminal device obtains the first time information of the second network device based on the first information. The terminal device obtains high-precision time information to improve communication reliability.

Abstract: A paging method includes: determining, by an access network device or a core network device, a paging cycle based on type information of a terminal, and sending first information based on the paging cycle, where the first information is used to page the terminal. The paging cycle is determined as 2.56 s according to the type information indicating that the terminal is REDCAP UE, so that the REDCAP UE can perform monitoring in the paging cycle of 2.56 s, receive emergency broadcast in time, and obtain energy saving gains. In some situations, a paging method includes receiving first information comprising information of a paging cycle for a terminal, and determining, according to type information of a camped cell on which the terminal is currently camped, whether to use PTW in monitoring paging in accordance with the first information.

Abstract: This application provides a random access resource selection method. The method includes: A terminal device obtains reference information; and when determining that a first parameter and the reference information meet a preset condition, selects a primary frequency domain resource or a non-primary frequency domain resource based on a first probability and a second probability, to initiate random access. There is a correspondence between the first probability and the primary frequency domain resource, and there is a correspondence between the second probability and the non-primary frequency domain resource. In embodiments of this application, frequency resources are selected, based on different probabilities, for random access triggered by an emergency and random access triggered by another event.

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.
