Abstract
One embodiment is directed wirelessly communicating with user equipment (UE) operating using discontinuous reception (DRX). When a rank for the UE has changed is determined and, in response when that happens, if an ON duration for a current DRX cycle for the UE will elapse during a current subframe is determined. In response to making such determination about the ON duration, a dummy assignment of resource blocks on a downlink shared channel is sent to the UE. The UE extends the ON duration of the current DRX cycle in response to the dummy assignment. If a channel quality indication (CQI) report has been made by the UE is determined and, in response thereto, a modulation and coding scheme (MCS) used for communicating with the UE is updated based on the reported rank and reported CQI. The dummy assignment is not made for communicating actual data to the UE.
