Transmitting Uplink Control Information

Abstract

In accordance with some embodiments, uplink control information, including a channel quality index, may be transmitted using at least two layers. As a result, more information can be provided for use in situations, such as those involving carrier aggregation, where information for a large number of component carriers must all be provided on one primary component carrier.

What is claimed is: 
     
         1 . A method comprising:
 aperiodically providing channel quality information; and   using a physical uplink shared channel having at least two layers to provide said information.   
     
     
         2 . The method of  claim 1  including providing channel quality information using two layers with two modulation-coding-schemes. 
     
     
         3 . The method of  claim 1  including using at least two codewords. 
     
     
         4 . The method of  claim 3  including using link adaptation. 
     
     
         5 . The method of  claim 3  including using layer shifting. 
     
     
         6 . The method of  claim 3  including using at least two layers with two modulation-coding-schemes. 
     
     
         7 . The method of  claim 1  including sending the same codeword over two different layers. 
     
     
         8 . A non-transitory computer readable medium storing instructions to enable a processor to:
 aperiodically provide channel quality information; and   send said information over a physical uplink shared channel having at least two layers.   
     
     
         9 . The medium of  claim 8  further storing instructions to provide channel quality information using two layers with two modulation-coding-schemes. 
     
     
         10 . The medium of  claim 8  further storing instructions to use at least two codewords. 
     
     
         11 . The medium of  claim 10  further storing instructions to use link adaptation. 
     
     
         12 . The medium of  claim 10  further storing instructions to use layer shifting. 
     
     
         13 . The medium of  claim 10  further storing instructions to use at least two layers with two modulation-coding-schemes. 
     
     
         14 . The medium of  claim 8  further storing instructions to send the same codeword over two different layers. 
     
     
         15 . A mobile station comprising:
 a processor to aperiodically provide channel quality information; and   a wireless transceiver to send the information over a physical uplink shared channel having at least two layers.   
     
     
         16 . The station of  claim 15  said processor to provide channel quality information using two layers with two modulation coding schemes. 
     
     
         17 . The station of  claim 15  said processor to use at least two codewords. 
     
     
         18 . The station of  claim 17  said processor to use link adaptation. 
     
     
         19 . The station of  claim 17  said processor to use layer shifting. 
     
     
         20 . The station of  claim 17  said processor to use at least two layers with two modulation coding schemes. 
     
     
         21 . The station of  claim 15  said processor to send the same codeword over two different layers. 
     
     
         22 . The station of  claim 15  wherein said station is a user equipment.
