Abstract: Methods and apparatuses are provided for wireless communication. Control symbols are mapped to a plurality of resource element groups (REGs) which is not assigned to a physical channel format indication channel (PCFICH) or a physical hybrid automatic repeat request indicator channel (PHICH). The mapped control symbols are transmitted on a packet dedicated control channel (PDCCH). A number of a plurality of resource elements (REs) in each of the REGs depends on an index of an orthogonal frequency division multiplexing (OFDM) symbol and a number of configured reference signals. A number of the REGs in a physical resource block (PRB) on an OFDM symbol depends on the index of the OFDM symbol and the number of configured reference signals.
