Abstract

Example implementations include receiving, by a wireless communication device from a network, an indication indicating activation status of two or more frequency resources, wherein each bit in a frequency resource indicator field of the indication maps to a corresponding one of the two or more frequency resources. In response to receiving the indication, the wireless communication device communicates with the network data using at least one of the two or more frequency resources.
