Abstract: A coordinated transmission control method, apparatus, and system. A primary access point and a secondary access point determine whether to perform coordinated transmission through inter-cell configuration parameter sharing and based on a dual decision condition of an interference test. An anti-interference beamforming manner is determined based on a specific cell configuration parameter, and whether to perform coordinated transmission is determined with reference to the dual decision condition of the interference test, wherein the primary and secondary access points learn an interference status in advance to prevent unnecessary retransmission resulting from interference caused during actual coordinated transmission.

Abstract: A transmission parameter obtaining method includes obtaining, by a terminal device, a transmission parameter of a network device, wherein the transmission parameter indicates location information of the network device. The method also includes determining, by the terminal device, at least one of an intra-frequency cell-reselection measurement threshold or an inter-frequency cell-reselection measurement threshold based on the transmission parameter. The method further includes determining, by the terminal device, a radio link failure threshold based on the transmission parameter. The method additionally includes determining, by the terminal device, at least one of an intra-frequency connected-state measurement threshold or an inter-frequency connected-state measurement threshold based on the transmission parameter.

Abstract: Example parameter optimization methods and apparatus are described. In one example parameter optimization method, a data processing device obtains a Kronecker factor matrix that is used to indicate a higher-order information matrix of a neural network model, and segments the Kronecker factor matrix to obtain a plurality of square matrices. The obtained plurality of square matrices are submatrices of the Kronecker factor matrix, and main diagonal lines of the plurality of square matrices each are in a one-to-one correspondence with a part of a main diagonal line of the Kronecker factor matrix. Then, the data processing device adjusts a parameter of the neural network model based on the obtained plurality of square matrices.

Abstract: This application provides a communication method and apparatus. An example method includes: A first core network device generates first information, and sends the first information to a first access network device, where the first information is used to indicate a service type and/or a service priority of a first service, the first service is a service of a first terminal device in a radio resource control (RRC) inactive state, and the first access network device is an anchor access network device of the first terminal device. The first core network device sends the first access network device the first information used to indicate the service type and/or the service priority of the first service of the first terminal device, so that the service type and/or the service priority of the first service may be carried when the first access network device pages the first terminal device.

Abstract: Embodiments of this application provide a paging method, a device, and a storage medium. The method includes: A core network device obtains time information of a paging moment at which a first network device pages a terminal device, and sends first message to the first network device based on the time information of the paging moment at which the first network device pages the terminal device, wherein the first message is used to page the terminal device. In the embodiments of this application, paging moments for paging the terminal device in various cells are dispersed. In this way, after the terminal device accesses a cell, the terminal device is no longer paged in another cell in which paging of the terminal device is not started. Therefore, paging overheads of paging the terminal device can be reduced in a paging area.

Abstract: A signal transmission method and an apparatus. The method includes: a location management device receives first SRS resource configuration information from a serving cell and/or a neighboring cell. The location management device sends second SRS resource configuration information to a terminal device, where the second SRS resource configuration information includes third SRS resource configuration information and a downlink reference signal associated with an SRS resource indicated by the third SRS resource configuration information, and the third SRS resource configuration information is a part or all of the first SRS resource configuration information. The location management device configures the SRS resource for the terminal device, so that the SRS resource can be associated with the downlink reference signal. This helps the terminal device obtain information about a transmission beam for sending an SRS, and therefore SRS receiving efficiency of the cell can be improved to some extent.
