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.
