Abstract

Certain aspects of the present disclosure relate to techniques for constructing a VHT-SIG field of a transmission preamble in a manner that may reduce peak-to-average power ratio (PAPR) of the transmission.

What is claimed is: 
     
         1 . A method for wireless communications, comprising:
 constructing a signal (SIG) field by applying a sequence of known bits to one or more information bits; and   transmitting the SIG field over a wireless channel.   
     
     
         2 . The method of  claim 1 , wherein applying a sequence of known bits to one or more information bits comprises performing a logical operation with the sequence of known bits. 
     
     
         3 . The method of  claim 2 , wherein at least one of the sequence of known bits or information bits comprise bits of an Association Identifier (AID). 
     
     
         4 . The method of  claim 3 , wherein:
 constructing the SIG field comprises performing a logical OR operation between the bits of the AID and the sequence of known bits.   
     
     
         5 . The method of  claim 1 , wherein at least one of the sequence of known bits or information bits comprise bits of a group Identifier (GID). 
     
     
         6 . An apparatus for wireless communications, comprising:
 means for constructing a signal (SIG) field by applying a sequence of known bits to one or more information bits; and   means for transmitting the SIG field over a wireless channel.   
     
     
         7 . The apparatus of  claim 6 , wherein the means for applying a sequence of known bits to one or more information bits comprises means for performing a logical operation with the sequence of known bits. 
     
     
         8 . The apparatus of  claim 7 , wherein at least one of the sequence of known bits or information bits comprise bits of an Association Identifier (AID). 
     
     
         9 . The apparatus of  claim 8 , wherein:
 the means for constructing the SIG field comprises means for performing a logical OR operation between the bits of the AID and the sequence of known bits.   
     
     
         10 . The apparatus of  claim 6 , wherein at least one of the sequence of known bits or information bits comprise bits of a group Identifier (GID). 
     
     
         11 . A non-transitory computer readable medium containing executable instructions for wireless communications, the executable instructions comprising instructions for:
 constructing a signal (SIG) field by applying a sequence of known bits to one or more information bits; and   transmitting the SIG field over a wireless channel.   
     
     
         12 . The non-transitory computer readable medium of  claim 11 , wherein applying a sequence of known bits to one or more information bits comprises performing a logical operation with the sequence of known bits. 
     
     
         13 . The non-transitory computer readable medium of  claim 12 , wherein at least one of the sequence of known bits or information bits comprise bits of an Association Identifier (AID). 
     
     
         14 . The non-transitory computer readable medium of  claim 13 , wherein:
 constructing the SIG field comprises performing a logical OR operation between the bits of the AID and the sequence of known bits.   
     
     
         15 . The non-transitory computer readable medium of  claim 11 , wherein at least one of the sequence of known bits or information bits comprise bits of a group Identifier (GID). 
     
     
         16 . A wireless node, comprising:
 at least one antenna;   a circuit configured to construct a signal (SIG) field by applying a sequence of known bits to one or more information bits; and   a transmitter configured to transmit the SIG field over a wireless channel via the at least one antenna.   
     
     
         17 . The wireless node of  claim 16 , wherein applying a sequence of known bits to one or more information bits comprises performing a logical operation with the sequence of known bits. 
     
     
         18 . The wireless node of  claim 17 , wherein at least one of the sequence of known bits or information bits comprise bits of an Association Identifier (AID). 
     
     
         19 . The wireless node of  claim 18 , wherein:
 constructing the SIG field comprises performing a logical OR operation between the bits of the AID and the sequence of known bits.   
     
     
         20 . The wireless node of  claim 16 , wherein at least one of the sequence of known bits or information bits comprise bits of a group Identifier (GID).
