Title:
METHODS AND APPARATUS FOR RANDOM ACCESS PROCEDURES WITH CARRIER AGGREGATION FOR LTE-ADVANCED SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2012/153960
Kind Code:
A2
Abstract:
An eNodeB is configured to perform a method for a random access procedure in an LTE-Advanced system. The method includes receiving from a user equipment a random access preamble message on a physical random access channel (PRACH) on a first cell, the PRACH associated with a random access radio network temporary identifier (RA-RNTI). The method also includes transmitting to the user equipment a random access response (RAR) message on a second cell. At least one of the RAR message and the RA-RNTI includes information configured to allow the user equipment to identify a target Timing Advance Group (TAG) or cell associated with the RAR message.
