Code division multiplexing group hopping for multi-transmission/reception point

A method for wireless communication at a first transmission/reception point, comprising:

• coordinating with a second transmission/reception point to configure code division multiplexing group hopping for a user equipment (UE);
• transmitting a signal to the UE indicating that code division multiplexing group hopping is enabled for the first transmission/reception point and the second transmission/reception point;
• transmitting, during a first instance of the code division multiplexing group hopping, a first reference signal to the UE according to a first code division multiplexing group;
• and
• transmitting, during a second instance of the code division multiplexing group hopping, the first reference signal to the UE according to a second code division multiplexing group.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor;
• and
• memory coupled to the processor, the processor and memory configured to:
• determine a first code division multiplexing group associated with a first transmission/reception point and a second code division multiplexing group associated with a second transmission/reception point;
• receive a signal indicating that code division multiplexing group hopping is enabled for the first transmission/reception point and the second transmission/reception point;
• receive, during a first instance of the code division multiplexing group hopping, a first reference signal from the first transmission/reception point according to the first code division multiplexing group and a second reference signal from the second transmission/reception point according to the second code division multiplexing group;
• and
• receive, during a second instance of the code division multiplexing group hopping, the first reference signal from the first transmission/reception point according to the second code division multiplexing group and the second reference signal from the second transmission/reception point according to the first code division multiplexing group.
