    Abstract: LOS ASPECTOS DE LA PRESENTE DESCRIPCIÓN PROPORCIONAN UN DISPOSITIVO INALÁMBRICO QUE SE COMUNICA CON OTRO DISPOSITIVO INALÁMBRICO QUE UTILIZA SUBTRAMAS AUTÓNOMAS. EL DISPOSITIVO INALÁMBRICO SE COMUNICA CON UNA ENTIDAD DE PROGRAMACIÓN QUE UTILIZA UNA PLURALIDAD DE SUBTRAMAS AUTÓNOMAS QUE INCLUYEN UNA PRIMERA SUBTRAMA Y UNA SEGUNDA SUBTRAMA. CADA UNA DE LAS SUBTRAMAS AUTÓNOMAS INCLUYE UNA PORCIÓN DE ENLACE ASCENDENTE (UL) Y UNA PORCIÓN DE ENLACE DESCENDENTE (DL). EL DISPOSITIVO INALÁMBRICO ADEMÁS RECIBE INFORMACIÓN DE CONTROL DE DL DE LA ENTIDAD DE PROGRAMACIÓN EN LA PORCIÓN DE DL DE LA PRIMERA SUBTRAMA, Y TRANSMITE DATOS DE UL QUE INCLUYEN UNA PLURALIDAD DE RÁFAGAS DE SEÑALES DE REFERENCIA A LA ENTIDAD DE PROGRAMACIÓN EN LA PORCIÓN DE UL DE LA PRIMERA SUBTRAMA. LA PLURALIDAD DE RÁFAGAS DE SEÑALES DE REFERENCIA SE SEPARAN UNIFORMEMENTE EN AL MENOS UNA PORCIÓN DE LA PORCIÓN DE UL DE LA PRIMERA SUBTRAMA.

    Abstract: The connection management entity apparatus determines a set of modems within coverage of a particular area. Each modem of the set of modems is associated with a particular aircraft and one carrier of a plurality of carriers. The apparatus allocates subsets of modems to each eNB of a set of eNBs. The allocation allows each eNB to communicate with the allocated subset of modems. Each eNB operates on a different carrier. The apparatus may be a eNB. The eNB determines a set of modems within coverage of the eNB. The set of modems is associated with one carrier of a plurality of carriers. The eNB operates on the one carrier. Each modem in the set of modems is associated with a different aircraft. The eNB sends information indicating the set of modems and receives an allocation of a second set of modems in response to the sent information.

    Abstract: The present patent application comprises a method and means for demodulating symbols, comprising converting an OFDM symbol from a time domain to a frequency domain, selecting pilot tones, making a soft decision based on received data, and estimating a channel frequency response. In another example, the method and means further comprises selecting guard tones. In another example, the method and means further comprises generating channel estimates for in-band and band-edge pilot tones.

    Abstract: A time averaging filter for channel estimation is described. Different time averaging is used for different taps or tones of a communication system. Two methods are suggested for determining the time-averaging filter for channel estimation for the communication systems without prior knowledge of SNR, channel Doppler and fading statistics. The first method includes a bank of different filters, each tuned for optimality in a certain range of SNR and Doppler. For each tone in the frequency domain (or tap in the time domain), the first method selects a filter among the set of filters that minimizes a certain computed metric. The second method directly computes, at each tone (or tap), the "best" filter in a least-squares sense, using empirically determined second-order statistics.

    Abstract translation: 描述了用于信道估计的时间平均滤波器。 不同的时间平均用于通信系统的不同抽头或音调。 建议两种方法用于确定用于通信系统的信道估计的时间平均滤波器，而无需SNR，信道多普勒和衰落统计信息。 第一种方法包括一组不同的滤波器，每个滤波器在一定范围的SNR和多普勒中被调整为最佳。 对于频域中的每个音调（或在时域中敲击），第一种方法选择一组过滤器，以使特定的计算度量最小化。 第二种方法使用经验确定的二阶统计量，在每个音调（或抽头）处直接计算最小二乘法中的“最佳”滤波器。

    Abstract: Certain aspects of the present disclosure provide techniques for transmitting and processing channel state information (CSI) reference signals (CSI-RS). An exemplary method includes determining a configuration of channel state information reference signals (CSI-RSs), wherein the configuration indicates a set of resource elements (REs) to be used for CSI-RSs and a first mapping of CSI-RS ports to the set of REs; sending an indication of the configuration of the CSI-RSs; and transmitting the CSI-RSs according to the determined configuration.
