Abstract
A wireless device may communicate with a base station. An indicator may be used to indicate that a wireless device-initiated report is to be transmitted by the wireless device. Monitoring of a downlink channel may be performed by the wireless device based on sending the indicator.
Claims20
A method comprising:
- receiving, by a wireless device, one or more radio resource control (RRC) messages comprising:
- one or more channel state information (CSI) report configuration parameters for wireless device-initiated CSI reporting, wherein the one or more CSI report configuration parameters comprise:
- a physical uplink control channel (PUCCH) resource configuration configured to indicate a PUCCH resource for a wireless device-initiated report indicator;
- and
- a report transmission mode parameter configured to indicate a transmission mode for the wireless device-initiated CSI reporting, wherein:
- a first value of the report transmission mode parameter indicates a first mode in which the wireless device-initiated CSI reporting is via a dynamically scheduled uplink resource;
- and
- a second value of the report transmission mode parameter indicates a second mode in which the wireless device-initiated CSI reporting is via a pre-configured uplink resource;
- and
- one or more discontinuous reception (DRX) configuration parameters configured to control physical downlink control channel (PDCCH) monitoring activity of the wireless device;
- sending, via the PUCCH resource and for the wireless device-initiated CSI reporting, a wireless device-initiated report indicator;
- monitoring a PDCCH in a DRX group while the DRX group is in an active time, wherein based on the report transmission mode parameter being set to the first value, the active time comprises a time after the sending the wireless device-initiated report indicator;
- receiving downlink control information (DCI) configured to schedule an uplink transmission via a physical uplink shared channel (PUSCH);
- and
- sending a CSI report via the PUSCH.

A method comprising:
- receiving, by a wireless device:
- a physical uplink control channel (PUCCH) resource configuration configured to indicate a PUCCH resource for a wireless device-initiated report indicator;
- a report transmission mode parameter configured to indicate a transmission mode for wireless device-initiated CSI reporting, wherein:
- a first value of the report transmission mode parameter indicates a first mode in which the wireless device-initiated CSI reporting is via a dynamically scheduled uplink resource;
- and
- a second value of the report transmission mode parameter indicates a second mode in which the wireless device-initiated CSI reporting is via a pre-configured uplink resource;
- and
- one or more discontinuous reception (DRX) configuration parameters configured to control physical downlink control channel (PDCCH) monitoring activity of the wireless device;
- detecting an event associated with wireless device-initiated CSI reporting;
- sending, via the PUCCH resource and based on the detecting the event, a wireless device-initiated report indicator;
- receiving downlink control information (DCI) configured to schedule an uplink transmission via a physical uplink shared channel (PUSCH);
- sending a CSI report via the PUSCH;
- and
- sending, via a second PUCCH resource, a second wireless device-initiated report indicator, wherein based on the report transmission mode parameter being set to the second value, an active time does not comprise a time after the sending the second wireless device-initiated report indicator.

A method comprising:
- receiving, by a wireless device, one or more radio resource control (RRC) messages comprising:
- one or more channel state information (CSI) report configuration parameters for wireless device-initiated CSI reporting, wherein the one or more CSI report configuration parameters comprise:
- a physical uplink control channel (PUCCH) resource configuration configured to indicate a PUCCH resource for a wireless device-initiated report indicator;
- a report transmission mode parameter configured to indicate a transmission mode for wireless device-initiated CSI reporting, wherein:
- a first value of the report transmission mode parameter indicates a first mode in which the wireless device-initiated CSI reporting is via a dynamically scheduled uplink resource;
- and
- a second value of the report transmission mode parameter indicates a second mode in which the wireless device-initiated CSI reporting is via a pre-configured uplink resource;
- and
- a cell discontinuous transmission or reception (DTX or DRX) configuration configured to indicate a cell DRX for a cell;
- detecting an event associated with wireless device-initiated CSI reporting;
- and
- based on not being in a cell DRX active period of the cell DRX, determining not to transmit, via the PUCCH resource and for the wireless device-initiated CSI reporting, a wireless device-initiated report indicator.
