Receiving a paging message

Abstract

Apparatuses, methods, and systems are disclosed for transmission of a paging message. One method includes receiving a system information block (SIB) indicating a configuration comprising a set of paging occasions and determining a paging frame based at least in part on an identifier of the UE and a discontinuous reception (DRX) cycle. The method includes determining a paging occasion index of a paging occasion based at least in part on the identifier of the UE and the paging frame and selecting the paging occasion from the set of paging occasions based at least in part on the paging occasion index of the paging occasion. The method includes monitoring the selected paging occasion for a paging of a physical downlink control channel (PDCCH) carrying a downlink control information (DCI).

         9 . The method of  claim 8 , further comprising:
 receiving the PDCCH carrying the DCI during the selected paging occasion.   
     
     
         10 . The method of  claim 8 , wherein each paging occasion of the set of paging occasions is associated with a respective paging occasion index. 
     
     
         11 . The method of  claim 8 , wherein the selected paging occasion begins within the paging frame. 
     
     
         12 . The method of  claim 8 , further comprising:
 determining one or more symbols associated with the selected paging occasion based at least in part on the configuration; and   monitoring for the paging of the PDCCH carrying the DCI during the one or more determined symbols associated with the selected paging occasion.   
     
     
         13 . The method of  claim 12 , wherein to determine the one or more symbols is based at least in part on a synchronization signal/physical broadcast channel block (SS/PBCH block). 
     
     
         14 . A processor comprising:
 a controller coupled with a memory and configured to cause the processor to:
 receive a system information block indicating a configuration comprising a set of paging occasions; 
 determine a paging frame based at least in part on an identifier of a user equipment (UE) and a discontinuous reception (DRX) cycle; 
 determine a paging occasion index of a paging occasion based at least in part on the identifier of the UE and the paging frame; 
 select the paging occasion from the set of paging occasions based at least in part on the paging occasion index of the paging occasion; and 
 monitor the selected paging occasion for a paging of a physical downlink control channel (PDCCH) carrying a downlink control information (DCI). 
   
     
     
         15 . The processor of  claim 14 , wherein the controller is further configured to cause the processor to:
 receive the PDCCH carrying the DCI during the selected paging occasion.   
     
     
         16 . The processor of  claim 14 , wherein each paging occasion of the set of paging occasions is associated with a respective paging occasion index.
