Claims64
A method in a user equipment, UE, the method comprising:
- determining a channel quality indicator, CQI, value corresponding to an error rate level among a plurality of error rate levels, and to a modulation and coding scheme, MCS, among a plurality of MCSs, the CQI value being determined based at least in part on at least one signal quality of signals received from a radio network node;
- transmitting the determined CQI value to the radio network node.
A user equipment, UE, operable to:
- determine a channel quality indicator, CQI, value corresponding to an error rate level among a plurality of error rate levels, and to a modulation and coding scheme, MCS, among a plurality of MCSs, the CQI value being determined based at least in part on at least one signal quality of signals received from a radio network node;
- transmit the determined CQI value to the radio network node.
A computer program product comprising a non-transitory computer readable storage medium having computer readable program code embodied in the medium, the computer readable program code comprising:
- computer readable program code to determine a channel quality indicator, CQI, value corresponding to an error rate level among a plurality of error rate levels, and to a modulation and coding scheme, MCS, among a plurality of MCSs, the CQI value being determined based at least in part on at least one signal quality of signals received from a radio network node;
- computer readable program code to transmit the determined CQI value to the radio network node.
A method in a radio network node, the method comprising:
- receiving a channel quality indicator, CQI, value from a user equipment, UE, the CQI value corresponding to an error rate level among a plurality of error rate levels, and to a modulation and coding scheme, MCS, among a plurality of MCSs, the CQI value being determined based at least in part on at least one signal quality of signals transmitted to the UE;
- performing at least one operational task based at least in part on the received CQI value.
