Abstract: Methods, systems, and devices for group-specific resource indications in mobile communication systems are described. An exemplary method for wireless communication includes determining, by a network node, an association among one set of one or more reference signals (RSs) and one or more groups, where each of the one or more RSs is associated with a usage or a time-domain behavior, and transmitting, to the terminal, a signaling message comprising the association. Another exemplary method for wireless communication includes determining, by the network node, a reference signal (RS) configuration, wherein the RS configuration comprises an association between one or more target RSs and a spatial granularity, and transmitting, to a terminal, a message comprising the RS configuration.
