Abstract: First indication information is newly added to a measurement configuration received by a terminal device, and the first indication information indicates the terminal device to perform grouping based on whether an MO is a first-type MO (that is, an MO corresponding to conditional handover CHO and/or an MO corresponding to conditional PSCell addition/change CPAC), and determine a measurement parameter of each group. Therefore, the terminal device groups a plurality of MOs into a first group of MOs (including only the first-type MO) and a second group of MOs (excluding the first-type MO), correspondingly determines measurement parameters, and measures each group of MOs by using various measurement parameters.

Abstract: This application relates to the field of communication technologies, and provides a communication method and apparatus, to determine a measurement periodicity in which a communication device performs layer 1 signal to interference plus noise ratio (L1-SINR) beam measurement based on a channel measurement resource (CMR) and an interference measurement resource (IMR). The method includes: A communication device receives a CMR and an IMR corresponding to the CMR. A terminal measures an L1-SINR of a receive beam based on the CMR and the IMR, to determine an optimal receive beam of the terminal. The CMR and the IMR are channel state information reference signal (CSI-RS) resources in different CSI-RS resource sets. The communication device determines a value of a first parameter based on repetition corresponding to a CSI-RS resource set corresponding to the CMR, and determines, based on the value of the first parameter, a measurement periodicity for measuring the L1-SINR.

Abstract: This application discloses a communication method and an apparatus. In a solution of this application, a base station sends, by using dedicated signaling, at least one random access parameter set to a terminal in a connected mode or an inactive mode. The base station receives a random access request of the terminal in a connected mode or an inactive mode. One of the at least one random access parameter set is used in the random access request. In this application, differentiated random access processes may be performed in different scenarios.

Abstract: This application provides a communication method and device. The method includes: A terminal device receives a reference signal from a network device, wherein the reference signal is not in a channel state information-reference signal (CSI-RS) resource set, configured with repetition on; and performs radio link monitoring (RLM) measurement or beam failure detection (BFD) measurement on the reference signal. According to the communication method and device provided in this application, the terminal device expects that the resource configured by the network device for performing BFD or RLM is not any resource in the CSI-RS resource set configured with the repetition on.

Abstract: A data sending method, a terminal device, an access network device, and a system are provided. The method includes: obtaining, by a terminal device, a sending period of first data; obtaining, by the terminal device, configuration information of a first resource; determining, a second resource based on the configuration information of the first resource and a sending period of the first data; and selecting, by the terminal device, a resource other than the second resource to send the first data. When selecting a resource used for V2X communications data or D2D communications data, the terminal device excludes the second resource that cannot be used for the V2X communications data or the D2D communications data, so as to avoid a conflict between the second resource and the resource selected by the terminal device for sending the first data, and improve reliability and security of D2D communication and V2X communication.

Abstract: A hard disk operation method and a hard disk manager, where in the method, the hard disk manager generates an instruction, encapsulates the instruction into a Management Component Transport Protocol (MCTP) packet, and sends the MCTP packet to a hard disk controller. The hard disk controller forwards the instruction to a hard disk. The hard disk executes an action according to the instruction. In this way, the hard disk manager may operate the hard disk based on the MCTP.
