Abstract
Systems, methods, and instrumentalities are described herein for idle mode mobility in an ultra-low power (ULP) system. Idle mode mobility in a ULP system may support energy efficient downlink signaling. An association may be identified between a Uu cell and a ULP cell. Switching between Uu cells may limit power savings gains from ULP receivers. Enabling switching between ULP cells without switching between Uu cells may help maintain the power savings gains from ULP receivers. A wireless transmit/receive unit may be configured to perform ULP cell reselection, for example, without triggering Uu cell reselection (e.g., to maintain power savings gains).
