Abstract: Embodiments of this application provide a resource preemption method, an apparatus, and a system, to reduce a quantity of times of frequent resource preemption, and improve resource security. In one example, a first terminal device obtains a first time interval and a second time interval, and preempts or determines not to preempt a first resource according to a first preset rule. The first resource is a resource reserved by a second terminal device or a resource reserved for a first service to be transmitted by the first terminal device. The first time interval is a time interval related to the first resource. The second time interval is used to indicate a preemption forbidden time. The first preset rule is determined based on the first time interval and the second time interval.

Abstract: A communication method and apparatus are provided. The method may be applied to a terminal and a network device. In the method, the network device first sends first indication information before sending a paging message, where the first indication information is used to indicate whether at least two terminals in an RRC_IDLE state or an RRC_INACTIVE state need to receive the paging message. In this way, after each of the at least two terminals receives the first indication information, the terminal may determine, based on the first indication information, whether the terminal needs to receive the paging message. If determining that the terminal needs to receive the paging message, the terminal may detect and receive the paging message on a corresponding time-frequency resource after the network device sends the paging message.

Abstract: A first terminal device determines a first physical random access resource, where the first terminal device is a first-type terminal device; the first terminal device sends a first random access request message on the first physical random access resource; the first terminal device receives first downlink control information DCI, where the first DCI is used to schedule a first random access response RAR. The first terminal device receives the first RAR based on the first DCI; and the first DCI and second downlink control information DCI received by a second terminal device are carried on a same physical downlink control channel PDCCH, and/or the first RAR and a second RAR scheduled by using the second DCI are carried on a same physical downlink shared channel PDSCH, where the second terminal device is a second-type terminal device.

Abstract: A method for determining a transmit power in a coverage enhancement scenario and a device resolve a problem that the prior art lacks a solution to determining a transmit power of a preamble sequence in a random access process in the coverage enhancement scenario. The method includes: obtaining, by a terminal, configuration information that is used to determine a transmit power used for transmitting a signal at each coverage enhancement level; and determining, by the terminal according to the obtained configuration information, a transmit power used for transmitting the signal at a coverage enhancement level currently used by the terminal, so as to determine the transmit power used for transmitting the signal in the coverage enhancement scenario.

Abstract: A communication method and apparatus are provided for transmitting packets of a data stream between user equipment. After receiving a first packet from a first user equipment, a user plane function (UPF) forwards the first packet to a second user equipment at a first moment, so that the first packet that arrives at the UPF before the first moment is not forwarded to the second user equipment until the first moment, to support deterministic sending and ensure that a time sensitive communication (TSC) packet is sent at a determined moment, so as to provide deterministic delay assurance for applications such as industrial control and telemedicine.
