Abstract: A system and a method minimize power consumption, signalling overhead, and processing load in blind scheduling in a mobile communication system. A User Equipment (UE) detects a type of an uplink (UL) grant while it is periodically allocated the UL grant. If there is no data to transmit using the UL grant, the UE determines whether to transmit a padding Medium Access Control (MAC) Protocol Data Unit (PDU) to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB) using the UL grant according to the type of the UL grant.

Abstract: An apparatus and method are provided for feeding back channel quality information and performing scheduling using the fed-back channel quality information in a wireless communication system based on Orthogonal Frequency Division Multiple Access (OFDMA). In the OFDMA wireless communication system, forward performance degradation due to a decrease in an amount of reverse channel quality information is reduced, and also an increase in the reverse load due to channel quality information feedback is suppressed. A base station controls power of a physical channel using information fed back from a mobile station. In a method for feeding back channel quality information from the mobile station, sub-band-by-sub-band channel quality information is measured and channel-by-channel quality information of a number of channels is transmitted in order of sub-bands of better channel quality information. Average channel quality information for a total band is measured and transmitted.

Abstract: Methods and apparatuses are provided for establishing time alignment by a User Equipment (UE) in a wireless communication system. Information for identifying a dedicated preamble on a downlink control channel is received from a base station. The dedicated preamble is transmitted to the base station based on the information. A response message to the transmitted dedicated preamble is received from the base station on a downlink shared channel. The response message includes a timing adjustment information and information for a Channel Quality Indicator (CQI) report. Time alignment is established based on the timing adjustment information included in the response message. The CQI report based on the information for CQI report is transmitted to the base station.
