Abstract: Frame structures and transmission techniques for a wireless communication system are described. In one frame structure, a super-frame includes multiple outer-frames, and each outer-frame includes multiple frames, and each frame includes multiple time slots. The time slots in each super-frame are allocated for downlink and uplink and for different radio technologies (e.g., W-CDMA and OFDM) based on loading. Each physical channel is allocated at least one time slot in at least one frame of each outer-frame in the super-frame. An OFDM waveform is generated for each downlink OFDM slot and multiplexed onto the slot. A W-CDMA waveform is generated for each downlink W-CDMA slot and multiplexed onto the slot. A modulated signal is generated for the multiplexed W-CDMA and OFDM waveforms and transmitted on the downlink. Each physical channel is transmitted in bursts. The slot allocation and coding and modulation for each physical channel can change for each super-frame.

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: Para transmitir datos en una forma que mitigue los efectos perjudiciales del esparcimiento de retardo, inicialmente se determinan las areas de cobertura esperadas para multiples transmisiones que se van a enviar en multiples ranuras de tiempo; las longitudes de prefijo ciclico para estas transmisiones se seleccionan con base en las areas de cobertura esperadas; la longitud de prefijo ciclico para cada transmision se puede seleccionar de entre un conjunto de longitudes permitidas de prefijo ciclico con base en el area de cobertura esperada para esa transmision, el escalonamiento piloto utilizado para la transmision, y asi sucesivamente; por ejemplo, se puede seleccionar una longitud mas corta de prefijo ciclico para cada transmision de area amplia; las longitudes de prefijo ciclico seleccionadas se pueden senalizar a las terminales; las transmisiones son procesadas (por ejemplo, moduladas por OFDM) con base en las longitudes seleccionadas de prefijo ciclico; las longitudes de prefijo ciclico se pueden seleccionar periodicamente, por ejemplo, en cada super-trama.

Abstract: Se describen tecnicas para transmitir datos en un sistema de comunicacion inalambrica; se identifican los canales fisicos que van a ser enviados en una super-trama y se les asignan ranuras de tiempo en la super-trama; la codificacion y modulacion para cada canal fisico se seleccionan con base en su capacidad; los datos para cada canal fisico son codificados selectivamente con base en una velocidad de codigo externo, por ejemplo, para un codigo Reed-Solomon, y se codifican adicionalmente con base en una velocidad de codigo interno, por ejemplo, para un codigo Turbo; los datos codificados para cada canal fisico son trazados para simbolos de modulacion con base en un esquema de modulacion seleccionado; los simbolos de modulacion para cada canal fisico son procesados adicionalmente (por ejemplo, modulados por OFDM) y multiplexados en las ranuras de tiempo asignadas al canal fisico; los datos que van a ser enviados utilizando otra tecnologia de radio (por ejemplo, W-CDMA) tambien son procesados y multiplexados en ranuras de tiempo asignadas para esta tecnologia de radio.

Abstract: Techniques for performing data detection and decoding in a manner to account for guard subbands are described. A receiver obtains received pilot symbols for pilot subbands and received data symbols for data subbands. Channel estimates are derived based on the received pilot symbols with zeroed-out pilot subbands filled with zeros. Data detection is performed on the received data symbols with the channel estimates to obtain data symbol estimates. Estimates of noise and estimation errors due to the zeroed-out pilot subbands are derived. LLRs are then computed based on the data symbol estimates, the channel estimates, and the estimates of the noise and estimation errors. The LLRs are deinterleaved and decoded to obtain decoded data.
