1. A wireless device in an Orthogonal Frequency Division Multiple Access (OFDMA) wireless system that uses a resource zone that includes a set of time-frequency resource units, the resource zone including at least some non-contiguous time-frequency resources, each time-frequency resource unit of the set of time-frequency resource units comprising specific contiguous time-frequency resources for receiving signals, the wireless device being capable of receiving data from a network device within a time-frequency resource unit of the set of time-frequency resource units, the wireless device comprising:
a receiver configured to receive control information associated with the resource zone that determines, for each time-frequency resource unit of the set of time-frequency resource units, a size in time-frequency resources and a position within the resource zone, wherein the time-frequency resources of the resource zone are mapped to the set of time-frequency resource units using the control information, wherein the control information includes an indication of a number of information elements in a sequence of information elements that follows the indication, and wherein the control information includes the sequence of information elements, each information element of the sequence of information elements including a user identifier and a modulation and coding scheme (MCS) index, the sequence of information elements including a first information element having a user identifier for the wireless device and an MCS index that identifies an MCS associated with the position of the time-frequency resource unit within the resource zone; and
a processor configured to recover the data based on the user identifier, the MCS, and an association between a position of the first information element in the sequence of information elements and the position of the time-frequency resource unit within the resource zone.
