OFDM symbol receiving and demodulating apparatus and demodulating method

摘要

Techniques are provided for a demodulation method and apparatus for a given user equipment device to receive (810) one or more Orthogonal Frequency Division Multiplex (OFDM) symbols over a control channel, where the OFDM symbols comprise a plurality of resource element groups distributed in time and frequency that are combined to form control channel elements. Those resource element groups that form specific control channel elements for the user equipment device and those resource element groups that form common control channel elements for one or more user equipment devices including the given user equipment device are identified (820). The resource element groups that form the specific control channel elements and the resource element groups that form the common control channel elements are demodulated (830) to generate encoded control messages comprising one or more control channel elements.
