Coordinated multipoint (CoMP) radio resource management (RRM) measurement
A method for measurement reporting is described. A measurement configuration is received from an evolved NodeB (eNB). The measurement configuration includes a single measurement object in a carrier frequency. A measurement report for a channel state information reference signal (CSI-RS) is generated based on the measurement configuration. The measurement report is sent to the eNB.
1. A method for measurement reporting performed by a user equipment (UE), comprising:
receiving a measurement configuration from an evolved Node B (eNB), wherein the measurement configuration comprises a single measurement object in a carrier frequency of each serving cell and the measurement configuration comprises a report configuration that corresponds to each of the measurement object of each of the serving cell and includes an indication of whether the report configuration is for cell-specific reference signal (CRS) or channel state information reference signal (CSI-RS);
generating a measurement report that includes the measurement results of all serving cells in case that more than one serving cell is configured, wherein each measurement result of each serving cell is based on cell-specific reference signal (CRS) or a channel state information reference signal (CSI-RS) according to the report configuration; and
sending the measurement report to the eNB.
2. The method of claim 1 , wherein the measurement results of each serving cell comprise one or both measurement results based on the CRS and on the CSI-RS.
3. A method for measurement reporting performed by an eNB, comprising:
determining measurement settings for a channel state information reference signal (CSI-RS) for a user equipment (UE);
generating a measurement configuration for the UE, wherein the measurement configuration comprises a single measurement object in a carrier frequency of each serving cell and the measurement configuration comprises a report configuration that corresponds to each of the measurement object of each of the serving cell and includes an indication of whether the report configuration is for cell-specific reference signal (CRS) or channel state information reference signal (CSI-RS);
sending the measurement configuration to the UE; and
receiving a measurement report that includes the measurement results of all serving cells in case that more than one serving cell is configured, wherein each measurement result of each serving cell is based on cell-specific reference signal (CRS) or a channel state information reference signal (CSI-RS) according to the report configuration.
4. The method of claim 3 , wherein the measurement results of each serving cell comprise one or both measurement results based on the CRS and based on the CSI-RS.
5. A user equipment (UE) configured for measurement reporting, comprising:
an operations module configured to:
receive a measurement configuration from an evolved Node B (eNB), wherein the measurement configuration comprises a single measurement object in a carrier frequency of each serving cell and the measurement configuration comprises a report configuration that corresponds to each of the measurement object of each of the serving cell and includes an indication of whether the report configuration is for cell-specific reference signal (CRS) or channel state information reference signal (CSI-RS);
generate a measurement report that includes the measurement results of all serving cells in case that more than one serving cell is configured, wherein each measurement result of each serving cell is based on cell-specific reference signal (CRS) or a channel state information reference signal (CSI-RS) according to the report configuration; and
send the measurement report to the eNB.
6. The UE of claim 5 , wherein the measurement results of each serving cell comprise one or both measurement results based on the CRS and based on the CSI-RS.
7. An evolved NodeB (eNB) configured for measurement reporting, comprising:
an operations module configured to:
determine measurement settings for a channel state information reference signal (CSI-RS) for a user equipment (UE);
generate a measurement configuration for the UE, wherein the measurement configuration comprises a single measurement object in a carrier frequency of each serving cell and the measurement configuration comprises a report configuration that corresponds to each of the measurement object of each of the serving cell and includes an indication of whether the report configuration is for cell-specific reference signal (CRS) or channel state information reference signal (CSI-RS);
send the measurement configuration to the UE; and
receive a measurement report that includes the measurement results of all serving cells in case that more than one serving cell is configured, wherein each measurement result of each serving cell is based on cell-specific reference signal (CRS) or a channel state information reference signal (CSI-RS) according to the report configuration.
8. The eNB of claim 7 , wherein the measurement results of each serving cell comprise one or both measurement results based on the CRS and based on the CSI-RS.
