Procedures for operating in long term evolution idle mode
Abstract
Various procedures for operating a wireless transmit/receive unit (WTRU) in Long Term Evolution (LTE) Idle mode are described. The procedures include: methods for applying cell reselection priorities in the WTRU, methods for converting a mobility state of the WTRU between operating modes, a method for assigning a mobility state to the WTRU, and a method for determining whether the WTRU may access a closed subscriber group (CSG) cell. Also described are methods and an apparatus on the operations of the LTE mobility state transition mechanism between LTE WTRU Idle mode and Connected mode, a definition of the Pcompensation parameter for LTE, inter-frequency and inter-radio access technology cell reselection priority validity definitions, and coverage extension principles for CSG cells.
