Abstract: Methods, systems, and devices related to reducing signaling overhead for uplink transmissions are described. In one representative aspect, a method for wireless communication includes transmitting, from the wireless communication node, a first message to a mobile device. The first message identifies one or more resource groups that correspond to a transmission rank to be used by the mobile device for a data transmission from the mobile device to the wireless communication node. The one or more resource groups are selected from a set of candidate resource groups or a set of candidate resources. The method also includes receiving, at the wireless communication node, the data transmission having the transmission rank from the mobile device.
