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 REGs are allocated based on a time first manner. The mapped control symbols are transmitted on a packet dedicated control channel (PDCCH). A number of the REGs in a physical resource block (PRB) on an orthogonal frequency division multiplexing (OFDM) symbol depends on an index of the OFDM symbol and a number of configured reference signals.

Abstract: A method and apparatus for transmitting and receiving downlink control information in a mobile communication system supporting an uplink packet data service are provided. To transmit packet data in an HARQ mobile communication system, a second transceiver receives an RG as rate control information from a first transceiver. The second transceiver sets the allowed maximum data rate of an HARQ process to which the RG is applied to the allowed maximum data rate of an HARQ process previous to the HARQ process, if the RG indicates hold. The second transceiver transmits packet data within the set allowed maximum data rate to the first transceiver.
