Abstract
According to certain embodiments, a method in a wireless device is provided that includes receiving, from a network node, dynamic allocation signaling to commence measurement on a semi-persistent CSI-RS resource. A first measurement is performed on the CSI-RS resource. A first CSI report based only on the first measurement is transmitted to the network node. A trigger message is received from the network node that is different from the dynamic allocation signaling. The trigger message triggers semi-persistent CSI reporting, and the wireless device initiates semi-persistent reporting.
Claims39
A method in a wireless device for initiating semi-persistent channel state information, CSI, measurements, the method comprising:
- receiving, from a network node, dynamic allocation signaling to commence measurement on a semi-persistent channel state information-reference signal, CSI-RS, resource;
- performing a first measurement on the semi-persistent CSI-RS resource;
- transmitting, to the network node, a first CSI report based only on the first measurement;
- receiving, from the network node, a trigger message that is different than the dynamic allocation signaling, the trigger message triggering semi-persistent CSI reporting;
- and
- initiating semi-persistent reporting.
A wireless device for initiating semi-persistent channel state information, CSI, measurements, the wireless device comprising:
- a memory storing instructions;
- and
- processing circuitry operable to execute the instructions to cause the wireless device to:
- receive, from a network node, dynamic allocation signaling to commence measurement on a semi-persistent channel state information-reference signal, CSI-RS, resource;
- perform a first measurement on the semi-persistent CSI-RS resource;
- transmit, to the network node, a first CSI report based only on the first measurement;
- receive, from the network node, a trigger message that is different than the dynamic allocation signaling, the trigger message triggering semi-persistent CSI reporting;
- and
- initiate semi-persistent reporting.

A method in a network node for initiating semi-persistent channel state information, CSI, measurements, the method comprising:
- transmitting, to the wireless device, dynamic allocation signaling to initiate measurement on a semi-persistent channel state information-reference signal, CSI-RS, resource for which the wireless device is not currently performing measurements;
- determining whether a first CSI report is transmitted by the wireless device in response to the dynamic allocation signaling;
- and
- taking an action based on whether the first CSI report is received in response to the dynamic allocation signaling.
