Abstract
Methods, systems, and devices for wireless communications are described. A wireless communications system may support techniques for channel state information (CSI) based artificial noise injection. In some cases, a base station may receive an indication of CSI associated with a channel for communications with the UE. The base station may apply artificial noise signals, based on the CSI, to a set of first signals associated with control channel transmissions to obtain a set of second signals. The UE may receive the set of second signals and apply pseudo-noise signals, based on the CSI, to the set of second signals to remove or reduce the artificial noise. The UE may combine the set of second signals adjusted by applying the pseudo-noise signals to obtain a combined signal. The UE may decode the combined signal to obtain control information.
