Abstract
A wireless transmit receive unit (WTRU) may be configured to receive an indication/configuration from a network regarding changes in information related to the serving cell's identity (e.g., Physical cell identity (PCI), Cell Global Identity (CGI), etc.), which may contain additional information such as the conditions when this change becomes effective. Upon the reception of this indication, and if a condition is also specified, fulfillment of the condition, the WTRU may be configured to consider the new PCI/CGI as the serving cell's PCI/CGI, consider the old PCI as belonging to a neighbor cell, and/or may update the security keys that are used for encryption and integrity protection based on the new PCI.
