摘要： In a mobile communication system and a broadcasting system, an Advanced Base Station (ABS) periodically broadcasts a buffering data packet of broadcast buffering content in providing a Mobile Internet Protocol TeleVision (Mobile IPTV) service. The broadcast buffering content represents content in which a buffering data packet corresponding to a predetermined buffering capacity is periodically broadcasted, and the buffering data packet represents a data packet that is transmitted to be buffered in advance before the broadcast buffering content is actually provided to Advanced Mobile Stations (AMSs).

摘要： A method and apparatus is provided for transmitting feedback information by each of user terminals in a communication system including the user terminals with different numbers of antennas. A multicast data packet is received from a base station through a downlink multicast transmission channel. If the multicast data packet has never been successfully decoded before, the multicast data packet is decoded and the success/failure in decoding the multicast data packet is determined. Upon the failure in decoding the multicast data packet, a NACK signal indicating the failure in decoding the multicast data packet is generated with sequences, the number of which is equal to the number of antennas of the user terminal. The NACK signal is transmitted to the base station through a shared feedback channel. If the user terminal has at least two antennas, sequences corresponding to the at least two antennas are orthogonal to each other and constitute sequence signals.

摘要： In an orthogonal frequency division multiplexing (OFDM) communication system using multiple transmit antennas, a first base sequence with a first length is segmented into a first number of second sequences to which different time offsets are applied. Subsequences of a first preamble sequence corresponding to the number of second sequences are generated. A second base sequence with a second length is segmented into a second number of third sequences to which different time offsets are applied. Subsequences of a second preamble sequence corresponding to the number of third sequences are generated. A subsequence is selected from the subsequences of the first preamble sequence and is transmitted through a transmit antenna in a first time interval. A third preset number of subsequences are selected from the subsequences of the second preamble sequence, and are mapped and transmitted to the transmit antennas in a second time interval.

摘要： An adaptive modulation scheme relating to an RA problem for maximizing the transmission rates of all users for maximum transmission rates in an OFDMA system including some users requiring to use services at fixed data rates. The scheme proposes introduction of an adaptive modulation using linear programming into an existing scheme for a system including a single kind of users, thereby enabling simultaneous execution of the adaptive modulation for all users in a system including two kinds of users. Further, the invention proposes another scheme of sequentially allocating subchannels to the users when the fixed transmission rate has a sufficiently small value, in order to reduce the complexity.
