Zusammenfassung:	A method and apparatus for encoding and decoding a data block are disclosed. The data block may be for a physical channel. Further, the data block may be for a shared channel. For data block encoding, a Node-B may calculate cyclic redundancy check (CRC) bits for the data block. The data block may be used to calculate the CRC bits. The Node-B may mask the CRC bits with a wireless transmit/receive unit (WTRU) identity (ID). Further, the Node-B may attached the masked CRC bits to the data block. Using a transmitter, the Node-B may transmit the data block over a physical channel. Further, the Node-B may transmit the data block over a shared channel. A WTRU may receive the data block, including the masked CRC bits. Using the WTRU ID, the WTRU may de-mask the CRC bits. The WTRU may perform a CRC check using the de-masked CRC bits.
