Method and radio node for handling CSI reporting
First Claim
1. A method performed by a User Equipment, UE, to handle separate aperiodic channel state information, CSI, reports for one or more static subframes, in which the direction of signal transmission is fixed, and one or more flexible subframes, in which the direction of signal transmission is variable, the method comprising:
- receiving a trigger for an aperiodic CSI report as part of an uplink, UL, grant from a radio node in a static downlink, DL, subframe, said trigger indicating a CSI subframe set related to the one or more static subframes;
reporting to the radio node, in a CSI reporting subframe, a result of an aperiodic CSI measurement for a CSI reference in the CSI subframe set;
receiving a second trigger for a second aperiodic CSI report as part of a second UL grant from the radio node in a second static DL subframe, said second trigger indicating a second CSI subframe set that relates to the one or more flexible subframes; and
reporting to the radio node, in a second CSI reporting subframe, a result of a second aperiodic CSI measurement for a second CSI reference in the second CSI subframe set.

Abstract
A radio node and a UE are described, and methods and computer programs therein to handle separate aperiodic CSI reports for one or more static subframes, in which the direction of signal transmission is fixed, and one or more flexible subframes, in which the direction of signal transmission is variable. The method performed by a UE comprises receiving a trigger for an aperiodic CSI report as part of an uplink grant from a radio node in a static downlink subframe, said trigger indicating a CSI subframe set related to the one or more static subframes. The method further comprises reporting to the radio node, in a CSI reporting subframe, a result of an aperiodic CSI measurement for a CSI reference in the CSI subframe set. The method further comprises receiving a second trigger that relates to the one or more flexible subframes and reporting the results to the radio node.

6. A non-transitory computer readable medium containing program code comprising instructions to be executed by at least one processor of a User Equipment, UE, to handle separate aperiodic channel state information, CSI, reports for one or more static subframes, in which the direction of signal transmission is fixed, and one or more flexible subframes, in which the direction of signal transmission is variable, whereby execution of the program code causes the at least one processor to perform operations comprising:
-
receiving a trigger for an aperiodic CSI report as part of an uplink, UL, grant from a radio node in a static downlink, DL, subframe, said trigger indicating a CSI subframe set related to the one or more static subframes; reporting to the radio node, in a CSI reporting subframe, a result of an aperiodic CSI measurement for a CSI reference in the CSI subframe set; receiving a second trigger for a second aperiodic CSI report as part of a second UL grant from the radio node in a second static DL subframe, said second trigger a second CSI subframe set that relates to the one or more flexible subframes; and reporting to the radio node, in a second CSI reporting subframe, a result of a second aperiodic CSI measurement for a second CSI reference in the second CSI subframe set. - View Dependent Claims (7, 8, 9, 10)

11. A User Equipment, UE, to handle separate aperiodic channel state information, CSI, reports for one or more static subframes, in which the direction of signal transmission is fixed, and one or more flexible subframes, in which the direction of signal transmission is variable, the UE comprising a processor, the processor configured to perform operations comprising:
-
receiving a trigger for an aperiodic CSI report as part of an uplink, UL, grant from a radio node in a static downlink, DL, subframe, said trigger indicating a CSI subframe set related to the one or more static subframes; reporting to the radio node, in a CSI reporting subframe, a result of an aperiodic CSI measurement for a CSI reference in the CSI subframe set; receiving a second trigger for a second aperiodic CSI report as part of a second UL grant from the radio node in a second static DL subframe, said second trigger a second CSI subframe set that relates to the one or more flexible subframes; and reporting to the radio node, in a second CSI reporting subframe, a result of a second aperiodic CSI measurement for a second CSI reference in the second CSI subframe set. - View Dependent Claims (12, 13, 14, 15)

16. A non-transitory computer readable medium containing program code comprising instructions to be executed by at least one processor of a radio node to handle separate aperiodic Channel State Information, CSI, reports for one or more static subframes, in which the direction of signal transmission is fixed, and one or more flexible subframes, in which the direction of signal transmission is variable, whereby execution of the program code causes the at least one processor to perform operations comprising:
-
indicating to a User Equipment, UE, in an uplink, UL, grant in a static downlink, DL, subframe, a first CSI subframe set in which the UE should perform an aperiodic CSI measurement for a first CSI reference resource, where the first CSI subframe sets relates to the one or more static subframes; receiving, in a CSI reporting subframe, a CSI report from the UE comprising a result of the aperiodic CSI measurement for a CSI reference resource in the first CSI subframe set; indicating to the UE, in a second UL grant in a second DL subframe, a second CSI subframe set in which the UE should perform a second aperiodic CSI measurement for a second CSI reference resource, where the second CSI subframe sets relates to the one or more flexible subframes; receiving, in a second CSI reporting subframe, a second CSI report from the UE comprising a result of the second aperiodic CSI measurement for the second CSI reference resource. - View Dependent Claims (17, 18, 19)
