User terminal and radio communication method
The present invention is designed to configure RRM measurement properly. A user terminal according to one aspect of the present invention has a receiving section that receives information about a parameter that is common among a plurality of resources for a reference signal, and a control section that controls, based on information about the parameter, reporting of results of measurement using the reference signal in part of the plurality of resources, and information about measured resources.
1. A terminal comprising:
a receiver that receives, for each cell to measure, a plurality of Channel State Information Reference Signal (CSI-RS) resource indices corresponding respectively to a plurality of CSI-RS resources and configuration information that is common to the plurality of CSI-RS resources; and
a processor that performs Radio Resource Management (RRM) measurement by using the configuration information and at least one of the plurality of CSI-RS resources,
wherein the receiver receives information indicative of synchronization signal block indices that are associated with the plurality of CSI-RS resource indices, and
the processor performs the RRM measurement by using a CSI-RS resource that is associated with a synchronization block index of a detected synchronization signal block.
2. The terminal according to claim 1 , wherein the CSI-RS resource associated is quasi-co-located (QCL) with the detected synchronization signal block.
3. The terminal according to claim 2 , wherein the configuration information indicates a band that is common to the plurality of CSI-RS resources.
4. The terminal according to claim 2 , wherein the receiver receives information indicative of a maximum number of measurement results to report.
5. The terminal according to claim 1 , wherein the configuration information indicates a band that is common to the plurality of CSI-RS resources.
6. The terminal according to claim 5 , wherein the configuration information indicates the band in units of Physical Resource Block (PRB).
7. The terminal according to claim 6 , wherein the receiver receives information indicative of a maximum number of measurement results to report.
8. The terminal according to claim 5 , wherein the receiver receives information indicative of a maximum number of measurement results to report.
9. The terminal according to claim 1 , wherein the receiver receives information indicative of a maximum number of measurement results to report.
10. A radio communication method for a terminal, comprising:
