Abstract: A method and apparatus for operating one or more satellites in a non-geosynchronous orbit (NGSO) satellite constellation are disclosed. In some aspects, a coverage area on Earth for a first beam transmitted from a first satellite in the NGSO satellite constellation may be determined, a cone may be projected onto a first region of the beam coverage area, a second region of the beam coverage area may be defined as including portions of the beam coverage area lying outside the first region, and a minimum arc angle for each of a plurality of points within the first region but not the second region of the beam coverage area may be determined.

Abstract: A method and apparatus for operating one or more satellites in a non-geosynchronous orbit (NGSO) satellite constellation are disclosed. In some aspects, the satellite may allocate a first frequency band to a first beam, and may allocate a second frequency band to a second beam. Then, if the first beam is disabled, the satellite may re-map the first frequency band from the first beam to the second beam. In this manner, frequency resources initially allocated to a disabled beam may be re-mapping to another, non-disabled beam.

Abstract: Briefly, in accordance with one embodiment, a method of adjusting for digital automatic gain control (DAGC) quantization error in a mobile station is as follows. A first DAGC value is stored before reception of one or more enhanced pilot signals. A second DAGC value is computed during reception of the one or more enhanced pilot signal. The first DAGC value is restored after reception of the one or more enhanced pilot signals is over. An advantage associated with this particular embodiment may include reduction in quantization error for digital automatic gain control.

Abstract translation: 简而言之，根据一个实施例，移动台中的数字自动增益控制（DAGC）量化误差的调整方法如下。 在接收到一个或多个增强导频信号之前存储第一DAGC值。 在接收一个或多个增强导频信号期间计算第二DAGC值。 在接收到一个或多个增强导频信号结束之后恢复第一个DAGC值。 与该特定实施例相关联的优点可以包括减少用于数字自动增益控制的量化误差。
