Problems solved by technology

[0003] However, under the CU-DU architecture, the DU cannot obtain the PCI information used by the adjacent access network equipment or other DUs under the same CU, and different CU-DU architectures may come from different manufacturers, and the corresponding operation and maintenance management ( Operation administration and maintenance (OAM) equipment is different, thus making physical cell identity (PCI) allocation more complicated

Abstract

The present application provides a communication method and device, which can provide a solution for allocating and optimizing PCI, and improve the efficiency of allocating PCI. The method includes: the distributed unit receives the first information sent by the centralized unit, the first information includes at least one of the following: PCI information, PCI information that is not allowed, and PCI conflict information; the distributed unit determines the distributed The PCI of the cell's serving cell.

Description

technical field [0001] The present application relates to the communication field, and in particular to a communication method and device. Background technique [0002] In the new communication standard, a new CU-DU architecture is defined for access network equipment. This architecture divides the access network equipment into two parts according to the function of the protocol stack, that is, a centralized unit (central unit, CU) and a distributed unit (distributed unit, DU). Both CU and DU are logical nodes, and one CU can be connected to one or more DUs to realize the functions of access network equipment. [0003] However, under the CU-DU architecture, the DU cannot obtain the PCI information used by the adjacent access network equipment or other DUs under the same CU, and different CU-DU architectures may come from different manufacturers, and the corresponding operation and maintenance management ( Operation administration and maintenance (OAM) equipment is differen...
