Abstract:
Example communications systems, methods and network devices are described. One example method includes sending a first message by a first access network device to a core network device to enable the core network device to send a second message to a second access network device, where the first message includes an identity of the second network device. The first message is used to request for X2 transport network layer (TNL) configuration information of a third network device, and the third network device is a network device that has established an X2 connection to the second network device. The first network device receives the X2 TNL configuration information of the third access network device from the second access network device. Therefore, a network device connected to a control plane of a core network can obtain TNL addresses of more network devices that are not connected to the control plane of the core network.
Abstract:
Embodiments of the present disclosure provide a multi-connectivity communication method and a device. An access network device of a first network determines to use an access network device of a second network to perform data splitting for data of UE, and then sends first splitting configuration information to the UE and sends second splitting configuration information to the access network device of the second network. The first splitting configuration information is used to notify the UE that the access network device of the second network is to split to-be-split data of the UE. The second splitting configuration information is used to instruct the access network device of the second network to split the to-be-split data of the UE.

A method for configuring a cell is provided. Configuration information of a first cell is obtained, wherein the configuration information comprises position information of one or more multicast broadcast single frequency network (MBSFN) sub-frames in a radio frame of the first cell. A radio frame of a second cell is configured according to the configuration information of the first cell. In the method for configuring the cell, interference between the first cell and the second cell is reduced.

Abstract:
This application provides a communication method and apparatus, which may be used for random access optimization. In this method, a CU may send, to a DU, obtained PRACH configuration information of a plurality of cells. The DU receives the PRACH configuration information of the plurality of cells from the CU, and performs random access optimization based on the PRACH configuration information of the plurality of cells. In an existing technology, a base station may adjust RACH configuration information of the base station based on PRACH configuration information of a neighboring base station, to perform random access optimization.

A communication method and an apparatus providing a PCI allocation and optimization solution are provided. The method includes that a distributed unit receives first information sent by a central unit, where the first information includes at least one of the following: allowed PCI information, unallowed PCI information, or PCI conflict information; and the distributed unit determines a PCI of a serving cell of the distributed unit based on the first information.
Abstract:
This application provides a communications method and device, and a computer-readable storage medium. The method includes: receiving an uplink data transmission threshold from a first network device, where the uplink data transmission threshold includes both a first transmission threshold and a second transmission threshold or includes a second transmission threshold. The first transmission threshold is used to indicate a maximum size of a data packet supported by the terminal device in a non-connected state on a first uplink carrier, and the second transmission threshold is used to indicate a maximum size of a data packet supported by the terminal device in the non-connected state on a supplementary uplink (SUL) carrier. The method further comprises determining, based on the uplink data transmission threshold and a size of a to-be-transmitted uplink data packet, to transmit, in the non-connected state, the uplink data packet on the first uplink carrier or the SUL carrier.
