Systems and methods for reduced overhead in wireless communication systems

A computer program product for wireless communications in a wireless network, comprising:

• a non-transitory computer-readable medium having program code recorded thereon, the program code including:
• program code to determine if a reference signal (RS) code-domain reduction pattern providing reduced overhead is to be used for at least one channel;
• and
• program code to communicate with a wireless node using the at least one channel based on the RS code-domain reduction pattern with reduced overhead.

An apparatus configured for wireless communication, the apparatus comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor,
• wherein the at least one processor is configured:
• to determine if a reference signal (RS) frequency-domain reduction pattern providing reduced overhead is to be used for at least one channel;
• and
• to communicate with a wireless node using the at least one channel based on a RS frequency-domain reduction pattern with reduced overhead.
