    Abstract: PROBLEM TO BE SOLVED: To provide a frame structure and a transmission technique for a wireless communication system. SOLUTION: In a single frame structure 200, a superframe includes a plurality of outer frames, each of the outer frames includes a plurality of frames, and each of the frames includes a plurality of time slots. The time slots in each superframe are allocated to downlink and uplink and to different wireless techniques (for example, W-CDMA and OFDM) based on loading. Each physical channel is allocated to time slots in the frames of each outer frame in the superframe. An OFDM waveform is generated for an OFDM slot of each downlink, a W-CDMA waveform is generated for a W-CDMA slot of each downlink, and the waveforms are multiplexed on each slot. A modulation signal is generated for the multiplexed W-CDMA and OFDM waveform and transmitted on the downlink. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a wireless communication system with a configurable cyclic prefix length.
    SOLUTION: To transmit data in a manner to mitigate the deleterious effects of delay spread, the expected coverage areas for multiple transmissions to be sent in multiple time slots are initially determined. Cyclic prefix lengths for these transmissions are selected based on the expected coverage areas. The cyclic prefix length for each transmission may be selected from among a set of allowed cyclic prefix lengths on the basis of the expected coverage area for that transmission, the pilot staggering used for the transmission, and so on. For example, a shorter cyclic prefix length may be selected for each local transmission, and a longer cyclic prefix length may be selected for each wide-area transmission. The selected cyclic prefix lengths may be signaled to the terminals.

    Abstract: PROBLEM TO BE SOLVED: To broadcast different types of transmission having different tiers of coverage in a wireless broadcast network. SOLUTION: Each base station processes data for a wide area transmission in accordance with a first mode (or coding scheme and modulation scheme) to generate data symbols for the wide area transmission and processes data for a local transmission in accordance with a second mode for the local transmission. The first and second modes are based on the coverage of for wide-area and local transmissions, respectively. The base station also generates pilots and overhead information for local and wide area transmissions. The data, pilots, and overhead information for local and wide area transmissions are multiplexed onto their transmission spans, which may be different sets of frequency subbands, different time segments, or different groups of subbands in different time segments. More than two different types of transmission may also be multiplexed and broadcast. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To multiplex multiple data streams in a multi-carrier communication system. SOLUTION: Disoverlapped interlaces are formed with U usable subbands. Each interlace is a different set of S subbands, and the subbands for each interlace are interlaced with the subbands for each of the other interlaces. M slots may be defined for each symbol period and assigned slot indices 1 through M. The slot indices may be mapped to interlaces such that (1) frequency diversity is achieved for each slot index and (2) the interlaces used for pilot transmission have varying distances to the interlaces used for each slot index. Each data stream may be processed as data packets of a fixed size, and different numbers of slots may be used depending on the coding and modulation scheme used for the data packet.
