Abstract
Systems and methods for triggering CSI reporting on PUCCH are described herein. A network node transmits a downlink-related control message including a Channel State Information (CSI) request field and a Physical Uplink Control Channel (PUCCH) resource indicator. A wireless device receives the control message and determines to trigger a CSI report in accordance with the CSI request field and the PUCCH resource indicator.
Claims23
A method performed by a wireless device, the method comprising:
- receiving a control message indicating a grant to schedule a Physical Downlink Shared Channel (PDSCH) transmission, the control message including:
- a Physical Uplink Control Channel (PUCCH) resource indicator indicating a resource for both transmitting a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) for the scheduled PDSCH transmission and transmitting a CSI report;
- and
- a Channel State Information (CSI) request field indicating whether to trigger CSI feedback on the PUCCH;
- determining to trigger a CSI report in accordance with the CSI request field;
- and
- transmitting the CSI report in accordance with the PUCCH resource indicator.
A wireless device comprising a radio interface and processing circuitry configured to:
- receive a control message indicating a grant to schedule a Physical Downlink Shared Channel (PDSCH) transmission, the control message including:
- a Physical Uplink Control Channel (PUCCH) resource indicator indicating a resource for both transmitting a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) for the scheduled PDSCH transmission and transmitting a CSI report;
- and
- a Channel State Information (CSI) request field indicating whether to trigger CSI feedback on the PUCCH;
- determine to trigger a CSI report in accordance with the CSI request field;
- and
- transmit the CSI report in accordance with the PUCCH resource indicator.
A method performed by a network node, the method comprising:
- transmitting a control message indicating a grant to schedule a Physical Downlink Shared Channel (PDSCH) transmission, the control message including:
- a Physical Uplink Control Channel (PUCCH) resource indicator indicating a resource for both transmitting a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) for the scheduled PDSCH transmission and transmitting a CSI report;
- and
- a Channel State Information (CSI) request field indicating whether to trigger CSI feedback on the PUCCH;
- and
- receiving a CSI report on a PUCCH resource in accordance with the transmitted control message.
