Abstract
A method of operating a wireless transmit receive unit (WTRU) and a WTRU configured to receive a radio link control (RLC)/a medium access control (MAC) header. The header is coded for reduced transmission time interval (RTTI) operation. The header includes a 16-bit cyclic redundancy check (CRC) of an RLC/MAC payload associated with the RLC/MAC header.

Claim
1. A method for use in a wireless transmit receive unit (WTRU), the method comprising:
receiving, at the WTRU, a radio link control (RLC)/medium access control (MAC) control block comprising a header and a control message payload, wherein the header is coded for reduced transmission time interval (RTTI) operation and comprises an 18-bit cyclic redundancy check (CRC) based only on the control message payload; and
decoding, at the WTRU, the RLC/MAC control block based on the 18-bit CRC.
2. The method as in claim 1, wherein the header includes four octets, and wherein eight bits of the 18-bit CRC are located in a second octet of the header, eight bits of the 18-bit CRC are located in a third octet of the header, and two bits of the 18-bit CRC are located in a fourth octet of the header.
3. The method as in claim 1, wherein the header is coded according to a Modulation and Coding Scheme 0(MCS-0).
4. The method as in claim 1, wherein the RLC/MAC header includes Relative Reserved Block Period (RRBP) information, Supplementary/Polling (S/P) information, Coding and Puncturing Scheme (CPS) information, and Uplink State Flag (USF) information.
5. The method as in claim 1, wherein the control block includes Radio Transaction Identifier (RTI) and Block Sequence Number (BSN) information.
6. A method for use in a base station, the method comprising:
generating, in the base station, a radio link control (RLC)/medium access control (MAC) control block comprising a header and a control message payload, wherein the header is coded for reduced transmission time interval (RRTI) operation and comprises an 18-bit error detection cyclic redundancy check (CRC) based only on the control message payload; and
transmitting, from the base station, the RLC/MAC control block to a wireless transmit/receive unit (WTRU).
7. The method as in claim 6, wherein the header includes four octets, and wherein eight bits of the 18-bit CRC are located in a second octet of the header, eight bits of the 18-bit CRC are located in a third octet of the header, and two bits of the 18-bit CRC are located in a fourth octet of the header.
8. The method as in claim 6, wherein the header is coded according to a Modulation and Coding Scheme 0 (MCS-0).
9. The method as in claim 6, wherein the RLC/MAC header includes Relative Reserved Block Period (RRBP) information, Supplementary/Polling (S/P) information, Coding and Puncturing Scheme (CPS) information, and Uplink State Flag (USF) information.
10. The method as in claim 6, wherein the control block includes Radio Transaction Identifier (RTI) and Block Sequence Number (BSN) information.
11. A wireless transmit receive unit (WTRU), the WTRU comprising:
a receiver configured to receive a radio link control (RLC)/medium access control (MAC) control block comprising a header and a control message payload, wherein the header is coded for reduced transmission time interval (RTTI) operation and comprises an 18-bit error detection cyclic redundancy check (CRC) based only on the control message payload; and
a processor configured to decode the RLC/MAC control block based on the 18-bit CRC.
12. The WTRU as in claim 11, wherein the header includes four octets, and wherein eight bits of the 18-bit CRC are located in a second octet of the header, eight bits of the 18-bit CRC are located in a third octet of the header, and two bits of the 18-bit CRC are located in a fourth octet of the header.
13. The WTRU as in claim 11, wherein the header is coded according to Modulation and Coding Scheme 0 (MCS-0).
