Method and apparatus for receiving site selection diversity transmit (SSDT) signal in a wideband code division multiple access (WCDMA) system

Abstract

Disclosed is a UE and a method to operate the UE in the Site Selection Diversity Transmit mode. The method includes detecting a case where no base station is transmitting to the UE; inserting predetermined values into a received signal; and decoding the predetermined values. The predetermined values preferably correspond to zero bits.

1 . A method to operate user equipment (UE) in a Site Selection Diversity Transmit mode, comprising: 
 detecting a case where no base station is transmitting to the UE;    inserting predetermined values into an output of a UE receiver; and    decoding the predetermined values.    
   
   
       2 . A method as in  claim 1 , where the predetermined values correspond to zero bits.  
   
   
       3 . User equipment (UE) operable in a Site Selection Diversity Transmit mode, comprising: 
 means for detecting a case where no base station is transmitting to the UE;    means for inserting predetermined values into an output of a UE receiver; and    means for decoding the predetermined values.    
   
   
       4 . User equipment as in  claim 3 , where the predetermined values correspond to zero bits.  
   
   
       5 . (canceled)  
   
   
       6 . (canceled)  
   
   
       7 . (canceled)  
   
   
       8 . A computer program product embodied on a computer readable medium execution of which operates user equipment (UE) in a Site Selection Diversity Transmit mode, comprising operations of: 
 detecting a case where no base station is transmitting to the UE;    inserting predetermined values into an output of a UE receiver; and    decoding the predetermined values.    
   
   
       9 . A computer program product as in  claim 8 , where the predetermined values correspond to zero bits.  
   
   
       10 . A computer program product as in  claim 8 , where the predetermined values are inserted instead of a correlator provided values.  
   
   
       11 . An integrated circuit installable in user equipment (UE) that is operable in a Site Selection Diversity Transmit mode, comprising circuitry responsive to a condition where no base station is transmitting to the UE to insert predetermined values into an output of a UE receiver and circuitry to decode the predetermined values.  
   
   
       12 . An integrated circuit as in  claim 11 , where the predetermined values correspond to zero bits.  
   
   
       13 . An integrated circuit as in  claim 11 , further comprising a plurality of correlators having outputs through which a received signal passes.  
   
   
       14 . An integrated circuit as in  claim 13 , wherein the predetermined values are inserted in place of values corresponding to the correlated received signal.  
   
   
       15 . A method as in  claim 1 , wherein the predetermined values are inserted instead of a correlator provided values.  
   
   
       16 . A method as in  claim 1 , wherein the predetermined values are sample values that correspond to soft bit values predetermined to not have a detrimental impact on the operation of a decoder.
