Method for encoding data unit by using a plurality of CRC algorithms
First Claim
1. A method of communicating data in a wireless communication system, the method comprising:
- receiving at least one data from an upper layer;
determining whether or not the at least one data is received through a common control channel (CCCH);
selecting a specific preamble included in a specific preamble group if it is determined that the at least one data is received through the CCCH;
transmitting the selected preamble to a network;
receiving a response message in response to the transmission of the selected preamble,wherein the response message includes an allocated radio resource for transmitting next scheduled data; and
transmitting the next scheduled data using the allocated radio resource,wherein the next scheduled data is transmitted by applying different cyclic redundancy checks (CRCs) according to types of data included in the next scheduled data such that an overhead of a medium access control protocol data unit (MAC PDU) included in the next scheduled data is minimized.

Abstract
A wireless communication system and a terminal providing a wireless communication service and to a method by which a base station and a terminal transmit and receive data in an evolved universal mobile telecommunications system (E-UMTS) evolved from universal mobile telecommunications system (UMTS) or a long term evolution (LTE) system, are disclosed. In transmitting RACH MSG 3 by a terminal to a base station, the terminal transmits the RACH MSG 3 by applying different cyclic redundancy checks (CRCs) according to types of data included in the RACH MSG 3, to thereby reduce overhead of a medium access control protocol data unit (MAC PDU) included in the RACH MSG 3.

4. A device configured to communicate data in a wireless communication system, comprising:
-
a processor configured to receive at least one data from an upper layer, determine whether or not the at least one data is received through a common control channel (CCCH), select a specific preamble included in a specific preamble group if it is determined that the at least one data is received through the CCCH, transmit the selected preamble to a network, receive a response message in response to the transmission of the selected preamble, wherein the response message includes an allocated radio resource for transmitting next scheduled data, and transmit the next scheduled data using the allocated radio resource, wherein the next scheduled data is transmitted by applying different cyclic redundancy checks (CRCs) according to types of data included in the next scheduled data such that an overhead of a medium access control protocol data unit (MAC PDU) included in the next scheduled data is minimized.
