Abstract: A method for configuring a cell includes the following steps. A network node obtains information for configuring serviceless Multicast Broadcast Single Frequency Network (MBSFN) sub-frames of a first cell; and the network node configures serviceless MBSFN sub-frames of a neighboring cell of the first cell by alternating the serviceless MBSFN sub-frames of the neighboring cell with the serviceless MBSFN sub-frames of the first cell according to the information for configuring the serviceless MB SFN sub-frames of the first cell. In the method for configuring the first cell, the serviceless MBSFN sub-frames of the neighboring cell alternate with the serviceless MBSFN sub-frames of the first cell, thereby reducing interference between cells and improving stability of the system.

Abstract: In a method for resolving PCT conflicts in a new radio (NR) network, synchronization signal and PBCH (Physical Broadcast Channel) blocks (SSB) and corresponding physical cell identifiers (PCIs) are utilized. In the method, a first PCI corresponds to a first SSB and a second PCI corresponds to a second SSB. An access network device determines, based on the first PCI and the second PCT, that the first PCI conflicts with the second PCI. In this way, PCI conflicts in an NR system can be detected to improve the success rate and to reduce the call drop rate in a terminal handover.

Abstract: Example multi-connectivity communication methods and apparatus are described. In one example method, 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. Then, the access network device of the first network 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.

Abstract: This application discloses a communication system including a master base station and a secondary base station, both connecting with a terminal. In the communication system, the master base station sends a first message to the secondary base station for allocating transmission resources for one or more flows to be transmitted between the secondary base station and a terminal, wherein the first message carries one or both of: identification information of each flow to be transmitted, and information of a data radio bearer (DRB) associated with each flow to be transmitted, then the secondary base station may determine a mapping relationship between a DRB and an admitted flow according to the first message. Moreover, the master base station sends DRB configuration information to the terminal. Therefore, requirements of 5G communication systems for QoS management of information transmission in a dual connectivity scenario can be met.
