Signaling power allocation parameters for uplink coordinated multipoint (comp)

Abstract

A method for obtaining multiple path loss parameters by a user equipment (UE) is described. A radio resource control (RRC) signaling message is received from a serving eNode B. A first transmit power corresponding to a first reference signal is obtained from the RRC signaling message. A second transmit power corresponding to a second reference signal is obtained from the RRC signaling message. A first path loss parameter is calculated using the first transmit power. A second path loss parameter is calculated using the second transmit power.

         2 . A method for obtaining information related to a Cell specific Reference Signal (CRS) by a user equipment, comprising:
 receiving the CRS;   receiving a Radio Resource Control (RRC) signaling message from a serving eNode B;   obtaining information related to only antenna ports 0-3, which correspond to an additional CRS, from the RRC signaling message.   
     
     
         3 . A user equipment configured for obtaining information related to a Cell specific Reference Signal (CRS), comprising:
 a processor; and   a memory in electronic communication with the processor; wherein   instructions are stored in the memory, the instructions being executable to:
 receive the CRS; 
 receive a Radio Resource Control (RRC) signaling message from a serving eNode B; and 
 obtain information related to only antenna ports 0-3, which correspond to an additional CRS, from the RRC signaling message. 
   
     
     
         4 . A method for signaling information related to a Cell specific Reference Signal (CRS) by a serving eNode B, comprising:
 generating the CRS;   generating a Radio Resource Control (RRC) signaling message that includes information related to only antenna ports 0-3, which correspond to an additional CRS; and   sending the RRC signaling message to a user equipment.   
     
     
         5 . An apparatus configured for signaling information related to a Cell specific Reference Signal (CRS), comprising:
 a processor; and   a memory in electronic communication with the processor; wherein   instructions are stored in the memory, the instructions being executable to:
 generate the CRS; 
 generate a Radio Resource Control (RRC) signaling message that comprises information related to only antenna ports 0-3, which correspond to an additional CRS; and 
 send the RRC signaling message to a user equipment.
