PDCCH is a physical channel that carries downlink control information (DCI) and it has characteristics as described below. Mapped to the first L OFDM symbols in every downlink subframe. Number of the symbols (L) for PDCCH can be 1,2, or 3. (This 'L' value is informed to UE by PCFICH) Number of the symbols for PDCCH is specified by PCFICH SpletA PDCCH is transmitted on one CCE or an aggregation of several consecutive CCEs, where a CCE corresponds to 9 Resource Element Groups (REGs). In PDCCH transmission, only those REGs are used which are not assigned to PCFICH or PHICH. Each REG contains 4 Resource Elements (REs).
