Abstract: An access node configures a User Equipment, UE, with a power saving monitoring pattern, and subsequently transmits a power saving signal configured to switch the UE from monitoring a downlink in accordance with a connected mode discontinuous reception, C-DRX, monitoring pattern to monitoring the downlink in accordance with the power saving monitoring pattern. For each of the monitoring patterns, monitoring the downlink in accordance with the monitoring pattern comprises monitoring the downlink only when a monitoring opportunity of the monitoring pattern is concurrent with a scheduled active interval of a C-DRX configuration of the UE.

The UE correspondingly receives the power saving signal and switches how it monitors the downlink accordingly.
