Abstract
A method of improving a random access procedure for handover in a user equipment (UE) of a wireless communication system is disclosed. The method includes steps of initiating a random access procedure for handover when performing a handover procedure, and repeating a random access preamble transmission when no valid random access response is received within a certain period of time or when contention of the random access procedure is considered not successful until the handover procedure succeeds or operation time of the handover procedure expires no matter whether a maximum number of the random access preamble transmission has been reached.
Claims20
A method of improving a random access procedure for handover in a user equipment (UE) of a wireless communication system, the method comprising:
- initiating a random access procedure for handover when performing a handover procedure;
- and
- repeating a random access preamble transmission when no valid random access response is received within a certain period of time or when contention of the random access procedure is considered not successful until the handover procedure succeeds or operation time of the handover procedure expires no matter whether a maximum number of the random access preamble transmission has been reached.
A communication device for improving a random access procedure for handover in a user equipment (UE) of a wireless communication system, the communication device comprising:
- a processor for executing a program code;
- and
- a memory coupled to the processor for storing the program code;
- wherein the program code comprises:
- initiating a random access procedure for handover when performing a handover procedure;
- and
- repeating a random access preamble transmission when no valid random access response is received within a certain period of time or when contention of the random access procedure is considered not successful until the handover procedure succeeds or operation time of the handover procedure expires no matter whether a maximum number of the random access preamble transmission has been reached.
