Using automatic gain control to indicate target sidelink receiving UE

An apparatus for wireless communication, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• transmit an automatic gain control (AGC) signal in an AGC symbol to a user equipment (UE), the AGC symbol indicating that the UE is a target of a sidelink communication based on a correspondence of the UE with a frequency domain location of a resource block (RB) including the AGC signal;
• and
• transmit sidelink data in the sidelink communication to the UE after the AGC signal.

• receive an automatic gain control (AGC) signal in an AGC symbol from a user equipment (UE), the AGC symbol indicating that the apparatus is a target of a sidelink communication based on a correspondence of the apparatus with a frequency domain location of a resource block (RB) including the AGC signal;
• and
• decode sidelink data in the sidelink communication from the UE in response to the AGC signal.
