Implementation of Physical Downlink Control Channel in LTE

The control channels in LTE are provided to support efficient data transmission. Control information about resource allocation or Uplink grants has to be sent to every UE in the form of Downlink Control Information (DCI) through Physical Downlink Control Channel (PDCCH). PDCCH. If UE fails to decode its intended DCI resources allocated in shared channel will become futile. PDCCH allocated with limited resources and every scheduled UE has to be served and serviced. These resources become scarcer as the number of UEs increase within the network. As such, the PDCCH design becomes crucial to meet continuously increasing demand for ever increasing data transmission. This thesis explains design of PDCCH, its performance is simulated in different channel conditions and conclusion for resource allocation every UE based on its channel conditions are drawn for better performance and efficient utilization of resources
