Terminal device, base station device, and communication method with multiple CSI processing
A terminal device configured to report CSI using multiple uplink cells. In a case that a total of the number of one or multiple first channel state information reports and multiple second channel state information reports in a first subframe exceeds a first certain number, a second certain number of channel state information reports of the one or multiple first channel state information reports and the multiple second channel state information reports are not updated. The second certain number is a number obtained by subtracting the first certain number from the total of the number of the one or multiple first channel state information reports and the number of the multiple second channel state information reports.
1. A terminal device comprising:
reception circuitry configured and/or programmed to receive, from a base station device, information for one or more aperiodic channel state information (CSI) reports, and information for one or more periodic CSI reports; and
transmission circuitry configured and/or programmed to transmit CSI reports, wherein
in a case that a quantity of the CSI reports to be transmitted exceeds a first number, the first number of the CSI reports with highest priority from the CSI reports are updated based on the priority, and
the priority is based on whether each of the CSI reports is an aperiodic CSI report or a periodic CSI report.
2. A base station device comprising:
transmission circuitry configured and/or programmed to transmit, to a terminal device, information for one or more aperiodic channel state information (CSI) reports, and information for one or more periodic CSI reports; and
reception circuitry configured and/or programmed to receive, from the terminal device, CSI reports, wherein
in a case that a quantity of the CSI reports to be received exceeds a first number, the first number of the CSI reports with highest priority from the CSI reports are updated based on the priority, and
the priority is based on whether each of the CSI reports is an aperiodic CSI report or a periodic CSI report.
3. A communication method used for a terminal device, the communication method comprising:
receiving, from a base station device, information for one or more aperiodic channel state information (CSI) reports, and information for one or more periodic CSI reports; and
transmitting CSI reports, wherein
in a case that a quantity of the CSI reports to be transmitted exceeds a first number, the first number of the CSI reports with highest priority from the CSI reports are updated based on the priority, and
the priority is based on whether each of the CSI reports is an aperiodic CSI report or a periodic CSI report.
4. A communication method used for a base station device, the communication method comprising:
transmitting, to a terminal device, information for one or more aperiodic channel state information (CSI) reports, and information for one or more periodic CSI reports; and
receiving, from the terminal device, CSI reports, wherein
in a case that a quantity of the CSI reports to be received exceeds a first number, the first number of the CSI reports with highest priority from the CSI reports are updated based on the priority, and
the priority is based on whether each of the CSI reports is an aperiodic CSI report or a periodic CSI report.
