Claim 9:
10. A user equipment comprising:
a receiver configured to:
receive a first plurality of bits in a physical downlink control channel (PDCCH) from a base station, wherein the first plurality of bits are scrambled by a first scrambling sequence, wherein the first scrambling sequence is based on a first initialization value, wherein the first initialization value is based on a cell identity (ID);
receive an enhanced physical downlink control channel (EPDCCH) configuration from the base station, wherein the EPDCCH configuration comprises a parameter; and
receive a second plurality of bits in an EPDCCH from the base station, wherein the second plurality of bits are scrambled by a second scrambling sequence, wherein the second scrambling sequence is based on a second initialization value, wherein the second initialization value is defined as follows:, C
    
     
      i
      ⁢
      n
      ⁢
      i
      ⁢
      t
     
     ,
     1
    
   
   =
   
    
     
      ⌊
      
       
        n
        s
       
       2
      
      ⌋
     
     ⁢

      9
     
    
    +
    
     N
     1
    
   
  
  ,
 

where the Cinit,1 is the second initialization value, the ns is a slot number within a radio frame and the N1 is the parameter.
