Methods and apparatus to reduce power consumption in user equipment (UE) that operates in a connected discontinuous reception (C-DRX) mode while in communication with wireless network are disclosed. A C-DRX warm-up period before the UE enters an on-duration is adjusted dynamically based on one or more factors including a time division duplex (TDD) uplink/downlink (UL/DL) subframe configuration, signal-to-noise ratio (SNR) values, and Doppler shift values. The C-DRX warm-up period is adapted based on the pattern of DL subframes in the UL/DL subframe configuration by including DL subframes that best contribute to channel estimation and adaptive tracking loops based on measured SNR and Doppler shift conditions. Favorable channel conditions, such as higher SNR and lower Doppler shift, can require fewer DL subframes and consequently shorter C-DRX warm-up periods. Higher Doppler shift values indicate more rapidly varying channel conditions and require DL subframes positioned closer to the start of the on-duration.
