Abstract

Methods, devices and systems for jointly encoding allocation information of one or more wireless communication stations in a common portion of a physical layer header are disclosed. In some examples, a wireless device may: generate allocation information associated with one or more wireless communication stations; encode the allocation information into the common portion of the physical layer header; and transmit the physical layer header to the one or more wireless communication stations.
