Signaling power allocation parameters for uplink coordinated multipoint (CoMP)
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.
1. A method for obtaining information related to a cell specific reference signal (CRS) by a user equipment (UE), comprising:
receiving the CRS;
receiving a radio resource control (RRC) signaling message from a serving eNode B;
obtaining information related to frequency resources allocated to an additional CRS and information related to only antenna ports 0 - 3 , which correspond to the additional CRS, from the RRC signaling message.
2. A user equipment (UE) 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 frequency resources allocated to an additional CRS and information related to only antenna ports 0 - 3 , which correspond to the additional CRS, from the RRC signaling message.
3. 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 comprises information related to frequency resources allocated to an additional CRS and information related to only antenna ports 0 - 3 , which correspond to the additional CRS; and
sending the RRC signaling message to a user equipment (UE).
4. 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 frequency resource allocation of an additional CRS and information related to only antenna ports 0 - 3 , which correspond to the additional CRS; and
send the RRC signaling message to a user equipment (UE).
