Abstract

Systems and methods are provided for enabling H-ARQ communication between a base station and one or more wireless terminals. Methods for enabling incremental redundancy (IR) based H-ARQ, Chase based H-ARQ and Space-Time Code combining (STC) based H-ARQ between devices for down-link and up-link direction transmissions are provided in the form of an information element (IE) for use with a Normal MAP convention as currently accepted in the draft version standard of IEEE 802.16. In addition, embodiments of the invention provide a resource management scheme to protect a network from abuse of resources from a wireless terminal not registered with the network. Components of the down-link and up-link mapping components of a data frame transmitted from the base station to one or more wireless terminals included messages that are readable by all wireless terminals as well as some messages that are encrypted and only readable by wireless terminals that are authenticated as being registered with the network.
