Abstract
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus operates in a first power mode with a first DL bandwidth in association with one of a radio resource control (RRC) idle state or an RRC connected state with a base station. The apparatus transitions to a second power mode with a second DL bandwidth less than the first DL bandwidth. Additionally, the apparatus monitors a set of symbols and a set of subcarriers of the second DL bandwidth for an activity indicator from the base station. The apparatus transitions from the second power mode to the first power mode upon receiving the activity indicator from the base station. In an aspect, control information associated with a modulation scheme may be within the set of symbols and the set of subcarriers. The control information may correspond to a particular constellation point.
