Reducing control channel overhead in advanced networks

Abstract

Controlling and reducing overhead in control channels in 5G or other next generation communication systems is provided herein. In connection with a data transmission between a device and a network node device, an overhead management component (OMC) can analyze one or more factors associated with the device, including speed or Doppler metric(s) of the device, type of service associated with the device, historical HARQ statistics for the device, configured threshold value for CSI estimation, device capability regarding redundancy version support, or other factor(s). Based on analysis results, OMC can determine whether to utilize a single redundancy version state or a multiple redundancy versions state. If the single redundancy version state is selected, OMC can generate control information that does not include redundancy version information, the control information being communicated via a control channel. OMC can communicate RRC signal to the device to indicate the determined redundancy version state.
