Abstract: Methods, systems, and devices for wireless communications are described. A first transmission/reception point (TRP) may coordinate with a second transmission/reception point to configure code division multiplexing group hopping for a user equipment (UE). The first TRP may transmit 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. The first TRP may transmit, 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. The first TRP may transmit, 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.
