METHOD FOR SIGNALING BACK-OFF INFORMATION IN RANDOM ACCESS
First Claim
Patent Images
1. A method for performing a random access procedure in a wireless communication system, the method comprising:
- transmitting a preamble for random access from a mobile station to a network;
receiving by the mobile station a random access response message from the network as a response to the preamble, the random access response message having a MAC (Medium Access Control) header; and
performing backoff using backoff information included in a MAC sub-header of the MAC header when a field in the MAC sub-header indicates that the MAC sub-header has the backoff information.

Abstract
A method for performing random access in a wireless communication system is provided. The method includes transmitting a preamble for random access in uplink, receiving a random access response message including back-off information as a response to the preamble, and performing back-off using the back-off information when the random access has failed.

6. A method for performing a random access procedure in a wireless communication system, the method comprising:
-
receiving at a network a preamble for random access from a mobile terminal; transmitting by the network a random access response message to the mobile terminal as a response to the preamble, the random access response message having a MAC (Medium Access Control) header, wherein the MAC header comprises a MAC sub-header including a field and backoff information configured to enable the mobile terminal to perform backoff when the field indicates that the MAC sub-header has backoff information. - View Dependent Claims (7, 8, 9, 10)
