    Abstract: Systems and methods are disclosed that facilitate wireless communication using resource utilization messages (RUMs), in accordance with various aspects. A RUM may be generated for a first node, such as an access point or an access terminal, to indicate that a first predetermined threshold has been met or exceeded. The RUM may be weighted to indicate a degree to which a second predetermined threshold has been exceeded. The first and/or second predetermined thresholds may be associated with various parameters associated with the node, such as latency, throughput, data rate, spectral efficiency, carrier-to-interference ratio, interference-over-thermal level, etc. The RUM may then be transmitted to one or more other nodes to indicate a level of disadvantage experienced by the first node.

    Abstract: 적응형 방식은 무선 노드들에 의한 간섭 관리 메시지들의 송신을 제어한다. 예를 들어, 적응형 방식은 자원 사용 메시지들을 송신할지 여부 및/또는 송신하는 방법을 결정하기 위해 사용될 수 있다. 그러한 결정은 예를 들어, 서비스 품질 임계값과 수신되는 데이터와 연관된 현재의 서비스 품질 레벨의 비교에 기초할 수 있다. 서비스 품질 임계값은 이전에 송신된 자원 사용 메시지들의 효과에 기초하여 조정될 수 있다. 주어진 무선 노드에 대한 서비스 품질 임계값은 무선 노드가 자원 사용 메시지들을 송신하는 빈도에 기초하여 조정될 수 있다. 주어진 무선 노드에 대한 서비스 품질 임계값은 다른 무선 노드로부터 수신되는 정보에 기초하여 조정될 수 있다. 조정 방식은 또한 주어진 무선 노드에 의해 수신되는 트래픽의 타입에 좌우될 수 있다. 서비스 품질 임계값은 또한 처리량 정보에 기초하여 조정될 수 있다.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for channel estimation in a system employing different transmission protocols as a broadcast/multicast protocol and a unicast protocol, wherein the number of a pilot tone used for broadcast transmission is greater than the number of a pilot tone used for a unicast transmission and quality of a symbol from a broadcast transmission slot is not deteriorated even when the symbol is adjacent to a symbol from a unicast transmission slot.SOLUTION: In the method, it is determined whether a first time-slot (multicast slot) of one transmission protocol is adjacent to a second time-slot (unicast slot) of another transmission protocol or not. The number of pilot power and/or a pilot sub-carrier is/are increased for an edge symbol of the multicast slot for a purpose of channel estimation using the edge symbol.

    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.
