Wake up signal (wus) dormancy

Abstract

A method of wireless communication is performed by a first device. The method includes receiving a wake up signal (WUS) indication via lower layer signaling. The method also includes performing a power saving operation based on the received WUS indication.

         14 . The apparatus of  claim 9 , in which the wake up signal indication is detected based on a scrambling code. 
     
     
         15 . The apparatus of  claim 9 , in which the wake up signal indication is detected from a known signature within an existing control channel field. 
     
     
         16 . The apparatus of  claim 9 , in which the wake up signal indication comprises an activation signal or a deactivation signal from media access control (MAC) layer signaling. 
     
     
         17 . An apparatus for wireless communication, comprising:
 means for receiving a wake up signal (WUS) indication via lower layer signaling; and   means for performing a power saving operation based on the received WUS indication.   
     
     
         18 . The apparatus of  claim 17 , in which the apparatus comprises a user equipment (UE).
