/**
 *  @file rg_sch_hdfdd.x This file gives the describes the design for Half
 *  Duplex FDD feature.
 *
 *  Half duplex FDD operation is one in which the UE cannot receive and 
 *  transmit at the same time. This is more of a UE limitation, chosen to 
 *  reduce the complexity of the UE's hardware. In LTE the half duplex FDD 
 *  is implemented such that the eNodeB schedules such that the UE doesn't 
 *  transmit and receive in the same subframe. The UE unless informed that a 
 *  subframe is for Uplink transmission continues to look at the PDCCH. 

 *  Due to the delay in switching from downlink to uplink, UE is unable to 
 *  receive the last few symbols of the subframe preceding the subframe 
 *  assigned for uplink transmissions.Half duplex FDD is a UE specific 
 *  configuration.
