Abstract: This application provides a communication method and apparatus, to improve communication security. The method includes: receiving first system information from a network device, where the first system information includes a first signature; determining a first digest based on the first signature; determining a second digest based on the first system information; and if the first digest matches the second digest, storing or applying the first system information. In embodiments of this application, a signature is carried in a field of system information, so that both a terminal device that supports the signature and a terminal device that does not support the signature can complete decoding of the system information. Specifically, the terminal device that supports the signature may perform verification by using a signature obtained through decoding.

Abstract: This application provides a method for performing data transmission by two terminal devices and an apparatus, so that only a spectrum resource needs to be occupied or fewer spectrum resources need to be occupied, and fewer spectrum resources are consumed, thereby helping alleviate a strain on spectrum resources. The method includes: A first core network device determines that a first terminal and a second terminal are in a mutual backup relationship. The first core network device sends pairing indication information to a base station, where the pairing indication information indicates that the first terminal and the second terminal are in the mutual backup relationship.

Abstract: Embodiments of this application provide example communication methods and apparatuses. One example method includes receiving, by a terminal device, N pieces of first information in N separate transmissions, where N is an integer greater than 1. The terminal device can then determine second information or transmission information of the second information based on at least a part of the N pieces of first information, where each of the N pieces of first information includes M bits, and M is an integer greater than or equal to 1.

Abstract: A random access method and apparatus are provided. The method includes: a terminal device obtains a position of the terminal device and a position of a network device, the terminal device determines a time adjustment value based on the position of the terminal device and the position of the network device, and the terminal device sends a random access preamble based on the time adjustment value and a random access channel (RACH) resource configured by the network device. Based on this solution, the terminal device may determine the time adjustment value based on the position of the terminal device and the position of the network device, and adjust a time for sending the random access preamble on the RACH resource. This helps avoid a problem that random access preamble receiving time windows overlap, thereby increasing a success rate of accessing the network device by the terminal device.

Abstract: Embodiments of this application disclose a random access method and apparatus. In one example method, when a terminal device supports positioning, the terminal device may adjust, based on a positioning capability, time for sending a preamble on a RACH Occasion (RO) resource. When the terminal device does not support positioning, a corresponding RO resource periodicity may be configured to be large. Therefore, regardless of whether the terminal device supports positioning, a network device can receive, at the same time or in a short preamble receiving time window, preambles sent on a same RO resource, and receive, at different time, in different small time ranges, or in different short preamble receiving time windows, preambles sent on different RO resources.

Abstract: Embodiments of this application provide a data transmission method and a communication apparatus. The method includes: A network device sends indication information to a terminal device, where the indication information is used to indicate a first transmission mode, and the first transmission mode includes: enabling a hybrid automatic repeat request function, disabling the hybrid automatic repeat request function, or at least one hybrid automatic repeat request mode. Therefore, after receiving the indication information sent by the network device, the terminal device determines the first transmission mode based on the indication information, and performs data transmission in the first transmission mode, to perform data transmission based on requirements of different services. In this way, flexibility of the data transmission is improved.
