Abstract
Channel state information (CSI) reporting may be used for wireless communications. CSI reporting may be activated or deactivated. At least one value associated with activation or deactivation of CSI reporting may be used to determine a transmission power for an uplink transmission.
Claims76
A method comprising:
- receiving, by a wireless device, a control message indicating an activation of channel state information (CSI) reporting;
- determining a transmission power for a transmission of at least one CSI report, wherein the transmission power is based on:
- at least one uplink power control parameter;
- and
- at least one value associated with the activation of CSI reporting;
- and
- transmitting, via an uplink channel and based on the transmission power, the at least one CSI report.
4 more elements
A method comprising:
- receiving, by a wireless device, at least one control message comprising at least one of:
- a first indication associated with an activation of channel state information (CSI) reporting;
- or
- a second indication associated with a deactivation of CSI reporting;
- determining, based on at least one of the first indication or the second indication, at least one value associated with at least one of:
- the activation of CSI reporting or the deactivation of CSI reporting;
- determining, based on the at least one value, a transmission power for a transmission of uplink information;
- and
- transmitting, via an uplink channel and based on the transmission power, the uplink information.
6 more elements
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- receive a control message indicating an activation of channel state information (CSI) reporting;
- determine a transmission power for a transmission of at least one CSI report, wherein the transmission power is based on:
- at least one uplink power control parameter;
- and
- at least one value associated with the activation of CSI reporting;
- and
- transmit, via an uplink channel and based on the transmission power, the at least one CSI report.
7 more elements
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- receive at least one control message comprising at least one of:
- a first indication associated with an activation of channel state information (CSI) reporting;
- or
- a second indication associated with a deactivation of CSI reporting;
- determine, based on at least one of the first indication or the second indication, at least one value associated with at least one of:
- the activation of CSI reporting or the deactivation of CSI reporting;
- determine, based on the at least one value, a transmission power for a transmission of uplink information;
- and
- transmit, via an uplink channel and based on the transmission power, the uplink information.
