Abstract
The link quality reporting method includes measuring link quality for received radio blocks, and if there is a modulation scheme with a largest number of radio blocks, reporting link quality for the modulation scheme, and if there is a plurality of schemes with the same number of radio blocks, reporting link quality for a modulation scheme selected using a predetermined method. Performance deterioration can be minimized in a link adaptation process.

A method of reporting link quality for radio blocks using a plurality of modulation schemes, the method comprising, performed in a mobile terminal:
- determining a link quality parameter for each modulation scheme and each timeslot assigned to the mobile terminal;
- determining the number of times each modulation scheme is used in each assigned timeslot over a reporting period;
- determining a subset of modulation schemes among a set of available modulation schemes;
- selecting a modulation scheme per timeslot from the subset of modulation schemes in accordance with the number of times each modulation scheme is used in each assigned timeslot;
- and
- reporting to a network, for each assigned timeslot, the selected modulation scheme and the link quality parameter corresponding to the selected modulation scheme.
A mobile terminal comprising a radio frequency (RF) unit adapted to receive radio blocks using a plurality of modulation schemes and a processor coupled with the RF unit and adapted for:
- determining a link quality parameter for each modulation scheme and each timeslot assigned to the mobile terminal;
- determining the number of times each modulation scheme is used in each of the assigned timeslot over a reporting period;
- determining a subset of modulation schemes among a set of available modulation schemes;
- selecting a modulation scheme per timeslot from the subset of modulation schemes in accordance with the number of times each modulation scheme is used in each assigned timeslot;
- and
- reporting to a network, for each assigned timeslot, the selected modulation scheme and the link quality parameter corresponding to the selected modulation scheme.
