31 * @file rg_sch_hdfdd.x This file gives the describes the design for Half
34 * Half duplex FDD operation is one in which the UE cannot receive and
35 * transmit at the same time. This is more of a UE limitation, chosen to
36 * reduce the complexity of the UE's hardware. In LTE the half duplex FDD
37 * is implemented such that the eNodeB schedules such that the UE doesn't
38 * transmit and receive in the same subframe. The UE unless informed that a
39 * subframe is for Uplink transmission continues to look at the PDCCH.
41 * Due to the delay in switching from downlink to uplink, UE is unable to
42 * receive the last few symbols of the subframe preceding the subframe
43 * assigned for uplink transmissions.Half duplex FDD is a UE specific
