Method and apparatus for performing random access on a secondary carrier

摘要

Methods and apparatus are described herein for synchronizing timing when using a secondary component carrier (SCC) in a carrier aggregated wireless network. A user equipment (UE) may determine that it is out of synchronization with respect to an SCC used to communicate with a network element. The UE may inform the network element of the out of synchronization status, and may perform a random access procedure to synchronize the timing.

1. A method for synchronizing timing related to a secondary component carrier (SCC) in carrier aggregated wireless networks, comprising:
determining an out-of-synchronization status with respect to the SCC utilized to communicate with an eNodeB; signaling an indication of the out-of-synchronization status to the eNodeB over a primary component carrier utilized to communicate with the eNodeB or another eNodeB; and performing a random access procedure with the eNodeB to synchronize timing for communicating over the SCC.
