An apparatus, system, and 5 method for reliable decoding of control information during LTE wireless transmissions is described. A mobile device may decode the PCFICH blindly, which may include obtaining resource elements (REs) that are reserved for Physical Downlink Control Channel (PDCCH), based on a largest value of a control format indicator (CFI), finding a total number of control channel elements (CCEs) according to the obtained REs, numbering the CCEs, and decoding the PDCCH for the largest value of the CFI over the numbered CCEs. Accordingly, the mobile device does not need to decode the PCFICH specifically. The mobile device may indicate to the NW that the mobile device is a constrained device, and the NW may responsively transmit control information using a reserved control format indication value corresponding to the UE being indicated as a constrained device. The mobile device may then not need to decode the PCFICH, and decode the PDCCH based on the PDCCH occupying a first four OFDM symbols. |
