Terminal, radio communication method, and base station

Abstract

A terminal according to an aspect of the present disclosure includes a control section that assumes that a first rank indicated by first channel state information (CSI) and a second rank indicated by second CSI are subjected to a given restriction, and controls creation of a joint CSI report including the first CSI and the second CSI, and a transmitting section that transmits the joint CSI report. According to an aspect of the present disclosure, measurement and report of CSI for a multi panel/TRP can be appropriately performed.

1 . A terminal comprising:
 a control section that assumes that a first rank indicated by first channel state information (CSI) and a second rank indicated by second CSI are subjected to a given restriction, and controls creation of a joint CSI report including the first CSI and the second CSI; and   a transmitting section that transmits the joint CSI report.   
     
     
         2 . The terminal according to  claim 1 , wherein the control section assumes that a total rank of the first rank and the second rank does not exceed a rank indicated by UE capability. 
     
     
         3 . The terminal according to  claim 1 , wherein the control section controls the creation of the joint CSI report when a CSI report configuration including information indicating the joint CSI report is configured. 
     
     
         4 . The terminal according to  claim 1 , wherein the control section assumes that a channel measurement resource for the first CSI corresponds to an interference measurement resource for the second CSI, and controls the creation of the joint CSI reports. 
     
     
         5 . A radio communication method for a terminal, the radio communication method comprising:
 assuming that a first rank indicated by first channel state information (CSI) and a second rank indicated by second CSI are subjected to a given restriction, and controlling creation of a joint CSI report including the first CSI and the second CSI; and   transmitting the joint CSI report.   
     
     
         6 . A base station comprising:
 a transmitting section that transmits, to a terminal, configuration information for a joint CSI report including first channel state information (CSI) and second CSI; and   a receiving section that assumes that a first rank indicated by the first CSI and a second rank indicated by the second CSI are subjected to a given restriction, and receives the joint CSI report created by the terminal.   
     
     
         7 . The terminal according to  claim 2 , wherein the control section controls the creation of the joint CSI report when a CSI report configuration including information indicating the joint CSI report is configured. 
     
     
         8 . The terminal according to  claim 2 , wherein the control section assumes that a channel measurement resource for the first CSI corresponds to an interference measurement resource for the second CSI, and controls the creation of the joint CSI reports. 
     
     
         9 . The terminal according to  claim 3 , wherein the control section assumes that a channel measurement resource for the first CSI corresponds to an interference measurement resource for the second CSI, and controls the creation of the joint CSI reports.
