Systems and methods to encode and/or decode structured super-position coding to enhance control channel capacity are disclosed herein. User equipment (UE) may be configured to communicatively couple to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). A first UE and a second UE may be coupled to the eNB. Basic PDCCH may be sent to the second UE, and extra PDCCH may be sent to the first UE on the same time-frequency resource. The second UE may be able to decode the basic PDCCH as it normally does. The first UE may be able to decode the basic PDCCH for the second UE, cancel the basic PDCCH from the signal, and decode the extra PDCCH. The extra PDCCH may be restricted to certain positions relative to the basic PDCCH to simplify searching by the first UE.
