1. An information processing method used in a mobile station, the method comprising:
- receiving reference signals from a base station based on mode indication information including transmission scheme information regarding the reference signals; and
obtaining channel state information based on the reference signals,wherein the transmission scheme information is used to indicate whether the reference signals are BF CSI-RSs or NP CSI-RSs, andwherein the channel state information is obtained bydetermining whether the reference signals are the BF CSI-RSs or the NP CSI-RSs based on the transmission scheme information,performing a first process on the reference signals and obtaining the channel state information when the reference signals are the BF CSI-RSs, andperforming a second process on the reference signals and obtaining the channel state information when the reference signals are the NP CSI-RSs,wherein the second process is different from the first process.

2. A mobile station comprising:
-
a receiver configured to receive reference signals from a base station based on mode indication information including transmission scheme information regarding the reference signals; and a processor configured to obtain channel state information based on the reference signals, wherein the transmission scheme information is used to indicate whether the reference signals are BF CSI-RSs or NP CSI-RSs, and wherein the processor is configured to determine whether the reference signals are the BF CSI-RSs or the NP CSI-RSs based on the transmission scheme information, perform a first process on the reference signals and obtain the channel state information when the reference signals are the BF CSI-RSs, and perform a second process on the reference signals and obtain the channel state information when the reference signals are the NP CSI-RSs, and wherein the second process is different from the first process. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
