Abstract

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.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A Node-B comprising:
 a processor configured to calculate cyclic redundancy check (CRC) bits for a data block;   the processor configured to mask the CRC bits with wireless transmit/receive unit (WTRU) identity (ID) bits;   the processor configured to attach the masked CRC bits to the data block; and   a transmitter configured to transmit the data block.   
     
     
         2 . The Node-B of  claim 1  wherein the data block is used to calculate the CRC bits. 
     
     
         3 . The Node-B of  claim 1  wherein the transmitter is configured to transmit the data block over a physical channel. 
     
     
         4 . The Node-B of  claim 1  wherein the transmitter is configured to transmit the data block over a shared channel. 
     
     
         5 . A method implemented in a Node-B comprising:
 calculating cyclic redundancy check (CRC) bits for a data block;   masking the CRC bits with wireless transmit/receive unit (WTRU) identity (ID) bits;   attaching the masked CRC bits to the data block; and   transmitting the data block.   
     
     
         6 . The method of  claim 5  wherein the data block is used to calculate the CRC bits. 
     
     
         7 . The method of  claim 5  wherein the data block is transmitted over a physical channel. 
     
     
         8 . The method of  claim 5  wherein the data block is transmitted over a shared channel. 
     
     
         9 . A wireless transmit/receive unit (WTRU) comprising:
 a receiver configured to receive a data block, wherein the data block includes masked cyclic redundancy check (CRC) bits;   a processor configured to de-mask the CRC bits in the received data block, wherein identity (ID) bits of the WTRU are used to de-mask the CRC bits; and   the processor further configured to perform a CRC check on the received data block using the de-masked CRC bits.   
     
     
         10 . The WTRU of  claim 9  wherein the CRC bits have been calculated using the data block. 
     
     
         11 . The WTRU of  claim 9  wherein the receiver is configured to receive the data block over a physical channel. 
     
     
         12 . The WTRU of  claim 9  wherein the receiver is configured to receive the data block over a shared channel. 
     
     
         13 . A method implemented in a wireless transmit/receive unit (WTRU), comprising:
 receiving a data block, wherein the data block includes masked cyclic redundancy check (CRC) bits;   de-masking the CRC bits in the received data block, wherein identity (ID) bits of the WTRU are used to de-mask the CRC bits; and   performing a CRC check on the received data block using the de-masked CRC bits.   
     
     
         14 . The method of  claim 13  wherein the CRC bits have been calculated using the data block. 
     
     
         15 . The method of  claim 13  wherein the data block is received over a physical channel. 
     
     
         16 . The method of  claim 13  wherein the data block is received over a shared channel.
