摘要： An apparatus and method for providing handover support information in a mobile communication system are provided. A method for an Base Station (BS) to provide information necessary for measurement report trigger performance to a Mobile Station (MS) after the MS determines neighboring BSs in a mobile communication system includes, in a case where the MS is an active mode MS, providing a Time To Trigger (TTT) independently by a specific neighboring BS to the active mode MS and, in a case where the MS is an idle mode MS, providing a reselection time period (Treselection) independently by the specific neighboring BS to the idle mode MS.

摘要： 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.

摘要： Disclosed is a method for performing a random access by a user equipment (UE), including identifying a path loss and a size of a message that the UE will transmit after a transmission of a preamble, selecting a preamble set from at least two preamble sets based on a first threshold and a second threshold, wherein a first preamble set is selected if the path loss is less than the first threshold and the size of the message is greater than the second threshold, wherein a second preamble set is selected if the path loss is greater than or equal to the first threshold, or the size of the message is less than or equal to the second threshold, selecting a preamble from the selected preamble set, transmitting, to a base station, the selected preamble, receiving, from the base station, a random access response message including resource allocation information in response to the transmission of the selected preamble, and transmitting, to the base station, a radio resource control message based on the resource allocation information.

摘要： 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.

摘要： 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.
