摘要： A base station may generate and transmit a transport stream including a sequence of frames. A frame may include a plurality of partitions, where each partition includes a corresponding set of OFDM symbols. For each partition, the OFDM symbols in that partition may have a corresponding cyclic prefix size and a corresponding FFT size, allowing different partitions to be targeted for different collections of user devices, e.g., user devices having different expected values of maximum delay spread and/or different ranges of mobility. The base station may also dynamically re-configure the sample rate of each frame, allowing further resolution in control of subcarrier spacing. By allowing the cyclic prefixes of different OFDM symbols to have different lengths, it is feasible to construct a frame that confirms to a set payload duration and has arbitrary values of cyclic prefix size per partition and FFT size per partition. The partitions may be multiplexed in time and/or frequency.

摘要： Techniques are disclosed relating to generating and receiving radio frames with multiple portions that have different target geographic areas. A data frame may include a first partition that includes a physical layer encoding of first data to be transmitted in a first geographic area, where the first geographic area is defined by a first threshold distance from the one or more transmitters. The data frame may include a second that includes a physical layer encoding of second data to be transmitted in a second geographic area, where the second geographic area is defined by a second, greater threshold distance from the one or more transmitters.

摘要： Systems and methods for future-proofed control signaling are disclosed herein. A waveform enabling broadcast transmission of physical layer frames having variable parameters can be extended to allow for future additions to the control signaling structure without breaking compatibility with existing receivers. In some embodiments, new signaling parameters can be added in an existing portion of a preamble and the length of the modified parameter set can be indicated to legacy receivers. In some embodiments new signaling parameters can be added at the end of the existing preamble and viewed as reserved bits by legacy receivers.

摘要： Systems and methods for sampling clock alignment and time offset signaling are disclosed herein. A transmitter broadcasting symbol-aligned frames at multiple baseband sampling rates can benefit from generating the frames to have durations that can be represented by an integer number of samples at two or more of the baseband sampling rates. In some embodiments, a transmitter adds samples to a frame to ensure that its duration meets such a criteria. Furthermore, the problem of signaling network time in symbol-aligned frames is simplified by sampling clock alignment. Approaches for signaling time offset of a transmission to the nearest millisecond boundary are also presented.

摘要： A method for operating a transmitting device to communicate with a receiving device is described herein. The method includes the step of the transmitting device selecting a root index value from a set of root index values. The method further includes the step of the transmitting device generating a frequency domain Constant Amplitude Zero Auto-Correlation sequence based on the selected root index value. The method further includes the step of the transmitting device modulating the Constant Amplitude Zero Auto-Correlation sequence by a pseudo-noise sequence. The method further includes the step of the transmitting device generating an Orthogonal Frequency Division Multiplexing symbol, wherein the frequency domain Constant Amplitude Zero Auto-Correlation sequence modulated by the pseudo-noise sequence defines subcarrier values for the Orthogonal Frequency Division Multiplexing symbol. The method further includes the step of the transmitting device transmitting the Orthogonal Frequency Division Multiplexing symbol as an initial Orthogonal Frequency Division Multiplexing symbol of a preamble of a frame to the receiving device.

摘要： Systems and methods for implementing point of advertising purchasing include using mass media publications configured for or containing service, product or vendor transmittable signals, such as from radio frequency identification tags. In a preferred arrangement, a consumer perceiving an advertisement of the mass media publication may activate a reader in a portable communications device, such as a smart mobile or cellular phone, to receive information from the radio frequency signal associated with the advertisement to identify a vendor, product or service associated with the radio frequency identification. The smart mobile phone or communications device of the consumer may communicate with a system of a vendor across a network to order a product or product information from a system of the vendor over the network by using the information from the radio frequency identification.
