Abstract  Abstract

The present invention provides a method for allocating a physical layer cell identifier and a base station, where a target base station obtains a list of available physical layer cell identifiers (PCIs) sent by an operation and maintenance entity (OAM), and then selects a target from the available PCI list. Removing the limited PCI of the cell to obtain a selectable PCI set (S102); The target base station acquires the center frequency information of the neighboring cells of the serving cell through the X2 interface message, and obtains the first reference PCI set in a preset manner, wherein the cell base frequency information in the first reference PCI set Center frequency information of the target cell of the target base station is floating (S104); The target base station alternates the available PCI list and the first reference PCI set to form a second reference PCI set (S106); If the selectable PCI set is empty, randomly select one PCI from the second true PCI set to be the PCI of the target cell (S108); It is configured to include. The present invention improves the success rate of PCI configured for the target cell.
