Abstract:
This TD will present measurements in reverberation chamber (RC) for adaptive LTE
transmission. Based on the device reported CQI-PMI-RI, the base station makes a decision on
what MCS index, pre-coding and transmission mode to use. This enables measurement that
more closely resemble real network performance, and the test can cover both near cell and cell
edge performance in a single 10-15 min measurement.
Results from OTA measurements in RC on 802.11p nodes are also presented for different
channel models. Performance is analyzed as a function of Doppler (fading rate) for different
sizes of the 802.11p packet.
