摘要： A system and method for broadband multi-carrier communications. The system includes a base station, user equipment, and a transmission scheme manager. The base station transmits a downlink reference signal. The user equipment receives the downlink reference signal and acquires channel status information from the downlink reference signal for at least one available frequency band within a downlink frequency band. The transmission scheme manager is coupled to the base station and allocates a radio resource to the user equipment based on channel status feedback from the user equipment. The channel status feedback is at least partially based on the channel status information.

摘要： A random access preamble scheme involves generating first and second preambles, each preamble having at least two Zadoff-Chu (ZC) sequences, with the ZC sequences of the first preamble being different from the ZC sequences in corresponding positions of the second preamble. For example, between two different preambles that each have two different ZC sequences, the first ZC sequences of the two preambles are different from each other and the second ZC sequences of the two preambles are different from each other. In another embodiment, a receiving scheme involves transforming received ZC sequences into transformed ZC sequences. In an embodiment, the received ZC sequences are transformed by correlating the received ZC sequences with their one chip cycle-shifting sequence. Transformed ZC sequences can be used for correlation detection in a multi- user wireless communications system.

摘要： A system and method for retransmission of a data segment in a wireless communication system. The system includes a transmitter, a receiver, and a retransmission manager. The transmitter transmits a data segment over a plurality of resource blocks. The data segment includes a plurality of data packets. Each of the data packets corresponds to one of the resource blocks. The receiver receives the data segment from the transmitter and determines that the data segment is incorrectly received. The retransmission manager initiates the retransmission of the data segment in response to the determination that the data segment is incorrectly received. The transmitter retransmits each of the data packets individually in sequence using the resource blocks originally assigned to the data packets.
