Abstract
A method of managing modulation for transmission of data in anticipation of handover. When a source base station is serving a UE and determines that the UE is going to hand over to a target base station, the source base station automatically transitions to transmit data to the UE with a low-order MCS selected without regard to CQIs reported by the UE, or at least to apply an MCS corresponding with a CQI lower than that reported by the UE. By applying a low-order MCS to transmit data to the UE, the source base station may increase the likelihood that the data will arrive successfully at the UE, as the low-order MCS may be more tolerant to noise than higher-order MCSs.
