Abstract

Provided is an uplink feedback channel allocation method and apparatus used to feedback data to indicate whether data packets corresponding an enhanced physical downlink control channel (E-PDCCH) were successfully decoded. A terminal may use an additional resource area of an uplink feedback channel or may use an empty resource area of the uplink feedback channel to which feedback information of a data packet corresponding to a physical downlink control channel (PDCCH) is not allocated, to perform feedback.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A communication method of a terminal, the method comprising:
 receiving control information including an offset and resource information of data;   receiving the data based on the resource information;   determining a resource of feedback information for the data based on the offset and antenna port; and   transmitting the feedback information using the resource,   wherein the control information is received in an Enhanced-Physical Downlink Control CHannel (E-PDCCH).   
     
     
         2 . The method of  claim 1 ,
 wherein the determining of the resource of the feedback information comprises:
 determining the resource based on the following equation:
     n   PUCCH,0   (1)   =n   CCE   +N   PUCCH   (1)   +l+N   offset , and 
 
   wherein n(1)PUCCH,0 denotes the resource, nCCE denotes a first value related to the control information, N(1)PUCCH denotes a second value related to a higher layer, 1 denotes a third value related to the antenna port, and Noffset denotes the offset.   
     
     
         3 . The method of  claim 2 , wherein the first value is an index of a first Control Channel Element (CCE) used for transmission of the control information. 
     
     
         4 . The method of  claim 1 , wherein the offset is included in an offset field of the control information. 
     
     
         5 . The method of  claim 1 , wherein the feedback information is ACKnowledgment (ACK)/Negative ACKnowledgment (NACK) information. 
     
     
         6 . A communication method of a base station, the method comprising:
 transmitting control information including an offset and resource information of data;   transmitting the data; and   receiving feedback information for the data,   wherein a resource for the feedback information is determined based on the offset and antenna port,   wherein the control information is transmitted in an Enhanced-Physical Downlink Control CHannel (E-PDCCH).   
     
     
         7 . The method of  claim 6 ,
 wherein the resource is determined based on the following equation:
     n   PUCCH,0   (1)   =n   CCE   +N   PUCCH   (1)   +l+N   offset , and 
   wherein n(1)PUCCH,0 denotes the resource, nCCE denotes a first value related to the control information, N(1)PUCCH denotes a second value related to a higher layer, 1 denotes a third value related to the antenna port, and Noffset denotes the offset.   
     
     
         8 . The method of  claim 7 , wherein the first value is an index of a first Control Channel Element (CCE) used for transmission of the control information. 
     
     
         9 . The method of  claim 6 , wherein the offset is included in an offset field of the control information. 
     
     
         10 . The method of  claim 6 , wherein the feedback information is ACKnowledgment (ACK)/Negative ACKnowledgment (NACK) information. 
     
     
         11 . A terminal comprising:
 a receiver configured to receive control information including an offset and resource information of data, and to receive the data based on the resource information;   a controller configured to determine a resource of feedback information for the data based on the offset; and   a transmitter configured to transmit the feedback information using the resource,   wherein the control information is received in an Enhanced-Physical Downlink Control CHannel (E-PDCCH).   
     
     
         12 . The terminal of  claim 11 ,
 wherein the controller determines the resource based on the following equation:
     n   PUCCH,0   (1)   =n   CCE   +N   PUCCH   (1)   +l+N   offset , and 
   wherein n(1)PUCCH,0 denotes the resource, nCCE denotes a first value related to the control information, N(1)PUCCH denotes a second value related to a higher layer, 1 denotes a third value related to the antenna port, and Noffset denotes the offset.   
     
     
         13 . The terminal of  claim 12 , wherein the first value is an index of a first Control Channel Element (CCE) used for transmission of the control information. 
     
     
         14 . The terminal of  claim 11 , wherein the offset is included in an offset field of the control information. 
     
     
         15 . The terminal of  claim 11 , wherein the feedback information is ACKnowledgment (ACK)/Negative ACKnowledgment (NACK) information. 
     
     
         16 . A base station comprising:
 a transmitter configured to transmit control information including an offset and resource information of data, and to transmit the data; and   a receiver configured to receive feedback information for the data;   wherein a resource for the feedback information is determined based on the offset and antenna port, and   wherein the control information is transmitted in an Enhanced-Physical Downlink Control CHannel (E-PDCCH).   
     
     
         17 . The base station of  claim 16 ,
 wherein the resource is determined based on the following equation:
     n   PUCCH,0   (1)   =n   CCE   +N   PUCCH   (1)   +l+N   offset , and
