Self-configuration of a physical cell identity (PCI) at a cell

摘要

The present disclosure presents a method and an apparatus for self-configuring a physical cell identify (PCI) at a cell upon detecting a PCI confusion at a neighbor cell. For example, the method may include detecting that a PCI confusion exists at a second cell based on a message (e.g., configuration update message or a X2 setup response message) received from the second cell. The first cell may initiate a timer that is selected from a first timer and a second timer, the first timer longer in duration than the second timer. The first cell then configures a new PCI for the first cell when the timer expires or maintains a current PCI for the first cell when the timer is reset prior to expiration. As such, self-configuration of PCI at a cell may be achieved.

主权项

1. A method for self-configuring a physical cell identity (PCI) at a base station, comprising:
detecting, at a first base station, that a PCI confusion exists at a second base station based on a message received from the second base station, wherein the message is a configuration update message or a X2 setup response message; initiating a timer at the first base station in response to detecting that the PCI confusion exists at the second base station, wherein the timer is selected from a first timer and a second timer, and wherein the first timer is longer in duration than the second timer; detecting whether the timer is reset or expired; and maintaining a current PCI for the first base station in response to detecting the timer is reset prior to expiration.
