Method and apparatus of feedback signaling

Abstract

A method and apparatus of feedback signaling using a high speed dedicated physical control channel (HS-DPCCH) includes transmitting to a first cell a first uplink feedback signal that includes channel quality information (CQI) associated with the first cell A second uplink feedback signal that includes CQI information associated with a second cell is transmitted to the second cell.

 concatenate channel quality indicator (CQI) information associated with the first serving cell with CQI information associated with the second serving cell; and 
 send the concatenated HARQ information and the concatenated CQI information in a same subframe. 
   
     
     
         2 . The WTRU of  claim 1 , wherein the HARQ information associated with the first serving cell comprises a first HARQ acknowledgement (HARQ-ACK) message and the HARQ information associated with the second serving cell comprises a second HARQ-ACK message. 
     
     
         3 . The WTRU of  claim 1 , wherein the WTRU is configured with a plurality of serving cells and the plurality of serving cells comprise a plurality of serving dedicated high speed downlink shared channel (HS-DSCH) cells. 
     
     
         4 . The WTRU of  claim 1 , wherein the first serving cell is a primary HS-DSCH serving cell, and the second serving cell is a secondary HS-DSCH serving cell. 
     
     
         5 . The WTRU of  claim 1 , wherein the processor is further configured to channel code for the HARQ information associated with the first serving cell and the HARQ information associated with the second serving cell using a same channelization code. 
     
     
         6 . The WTRU of  claim 1 , wherein the processor is further configured to channel code the CQI information associated with the first serving cell and the CQI information associated with the second serving cell using a same channelization code. 
     
     
         7 . The WTRU of  claim 1 , wherein the processor is further configured to use a same scrambling code for sending the HARQ information associated with the first serving cell and the HARQ information associated with the second serving cell. 
     
     
         8 . The WTRU of  claim 1 , wherein the processor is further configured to use a same scrambling code for sending the CQI information associated with the first serving cell and the CQI information associated with the second serving cell. 
     
     
         9 . The WTRU of  claim 1 , wherein the processor is further configured to send the CQI information associated with the first serving cell and the CQI information associated with the second serving cell in two time slots. 
     
     
         10 . A method for sending feedback, the method comprising:
 concatenating hybrid automatic repeat requests (HARQ) information associated with a first serving cell with HARQ information associated with a second serving cell;   concatenating channel quality indicator (CQI) information associated with the first serving cell with CQI information associated with the second serving cell; and   sending the concatenated HARQ information and the concatenated CQI information in a same subframe.   
     
     
         11 . The method of  claim 10 , wherein the HARQ information associated with the first serving cell comprises a first HARQ acknowledgement (HARQ-ACK) message and the HARQ information associated with the second serving cell comprises a second HARQ-ACK message. 
     
     
         12 . The method of  claim 10 , wherein a WTRU associated with the feedback is configured with a plurality of serving cells and the plurality of serving cells comprise a plurality of serving dedicated high speed downlink shared channel (HS-DSCH) cells. 
     
     
         13 . The method of  claim 10 , wherein the first serving cell is a primary HS-DSCH serving cell, and the second serving cell is a secondary HS-DSCH serving cell 
     
     
         14 . The method of  claim 10 , further comprising:
 channel coding the HARQ information associated with the first serving cell and the HARQ information associated with the second serving cell using a same channelization code.   
     
     
         15 . The method of  claim 10 , further comprising:
 channel coding the CQI information associated with the first serving cell and the CQI information associated with the second serving cell using a same channelization code.   
     
     
         16 . The method of  claim 10 , further comprising:
 using a same scrambling code for sending the HARQ information associated with the first serving cell and the HARQ information associated with the second serving cell.   
     
     
         17 . The method of  claim 10 , further comprising:
 using a same scrambling code for sending the CQI information associated with the first serving cell and the CQI information associated with the second serving cell.   
     
     
         18 . The method of  claim 10 , wherein the CQI information associated with the first serving cell and the CQI information associated with the second serving cell are sent in two time slots.
