Abstract
This disclosure pertains to a terminal for a Radio Access Network, the terminal being adapted for transmitting a measurement report on received reference signaling. The measurement report is based on one report type out of a set of possible report types, the terminal determining the report type of the measurement report based on a measurement report type indication in a downlink control information message received by the terminal. There are also disclosed further related methods and devices.
Claims21
A terminal for a Radio Access Network, comprising:
- control circuitry and control radio circuitry collectively configured to:
- receive radio resource control (RRC) signaling indicating a plurality of channel state information (CSI) report types;
- receive downlink control information (DCI) comprising a CSI report type indication for an aperiodic CSI report and further comprising a scheduling indication separate from the CSI report type indication, the scheduling indication indicating time-frequency resources for transmitting the aperiodic CSI report and comprising a timing offset parameter K which is variable between 0 and a value larger than 0, wherein the timing offset parameter K indicates a number of subframes and is set to 0;
- determine, based on the received CSI report type indication, a CSI report type among the plurality of CSI report types and, based on the received scheduling indication, the timing offset for transmitting the aperiodic CSI report in response to the DCI;
- and
- transmit the aperiodic CSI report according to the CSI report type and the timing offset.

A method for operating a terminal in a Radio Access Network, comprising:
- receiving radio resource control (RRC) signaling indicating a plurality of channel state information (CSI) report types;
- receiving downlink control information (DCI) comprising a CSI report type indication for an aperiodic CSI report and further comprising a scheduling indication separate from the CSI report type indication, the scheduling indication indicating time-frequency resources for transmitting the aperiodic CSI report and comprising a timing offset parameter K which is variable between 0 and a value larger than 0, wherein the timing offset parameter K indicates a number of subframes and is set to 0;
- determining, based on the received CSI report type indication, a CSI report type among the plurality of CSI report types and, based on the received scheduling indication, the timing offset for transmitting the aperiodic CSI report in response to the DCI;
- and
- transmitting the aperiodic CSI report according to the CSI report type and the timing offset.
