Semi-persistent channel state information report

A method comprising:

• receiving, by a wireless device from a base station, a downlink control information comprising:
• a power control command of an uplink shared channel;
• a channel state information (CSI) request field;
• a hybrid automatic repeat request process number;
• and
• a redundancy version;
• performing a validation of the downlink control information for an activation of a semi-persistent CSI reporting based on:
• a radio network temporary identifier of the semi-persistent CSI reporting;
• the hybrid automatic repeat request process number being set to a first value;
• and
• the redundancy version being set to a second value;
• activating the semi-persistent CSI reporting indicated by the CSI request field in response to the validation being achieved;
• and
• transmitting, based on the activated semi-persistent CSI reporting, a semi-persistent CSI report via the uplink shared channel with a transmission power determined based on the power control command, wherein the power control command is not used to perform the validation.
