Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may modify, based at least in part on a secrecy key, an input or an output of at least one of binary scrambling, modulation, or orthogonal frequency division multiplexing (OFDM) tone mapping for a physical control channel signal, resulting in a secured physical control channel signal. The transmitter device may transmit, to a receiver device, the secured physical control channel signal. Numerous other aspects are described.

A transmitter device for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, collectively or individually configured to:
- modify, based at least in part on a secrecy key, an output of orthogonal frequency division multiplexing (OFDM) tone mapping for a physical control channel signal, resulting in a secured physical control channel signal;
- and
- transmit, to a receiver device, the secured physical control channel signal.
A receiver device for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, collectively or individually configured to:
- receive, from a transmitting device, a secured physical control channel signal;
- and
- retrieve information from the secured physical control channel signal by modifying, based at least in part on a secrecy key, an input of orthogonal frequency division multiplexing (OFDM) tone mapping.
A method of wireless communication performed by a transmitter device, comprising:
- modifying, based at least in part on a secrecy key, an output of orthogonal frequency division multiplexing (OFDM) tone mapping for a physical control channel signal, resulting in a secured physical control channel signal;
- and
- transmitting, to a receiver device, the secured physical control channel signal.
A method of wireless communication performed by a receiver device, comprising:
- receiving, from a transmitting device, a secured physical control channel signal;
- and
- retrieving information from the secured physical control channel signal by modifying, based at least in part on a secrecy key, an input of orthogonal frequency division multiplexing (OFDM) tone mapping.
