Downlink control channel design and signaling
By configuring CCE size with finer resolution and dynamically adjusting DCI content, the inefficiencies of fixed CCE sizes and DCI message sizes in wireless communications are addressed, improving resource utilization and reducing latency.

Abstract
Methods, systems, and devices for wireless communications are described. According to techniques described herein, the network may configure control channel element (CCE) size according to various resolutions. In some examples, a modulation and control scheme (MCS) table may be defined and configured for a control channel and may indicate different CCE sizes for a control channel. A control channel may be modified such that a CCE size is a fraction of or integer number of a default CCE size. The CCE size may be bandwidth or bandwidth part dependent. In some examples, a control message (e.g., a downlink control information (DCI)) message size may be reduced. For example, a subset of control content may be predefined or fixed, or may be changed dynamically, or additional control information may be retrieved via an index value (e.g., in the DCI).
