Abstract: Methods and apparatus are provided for power saving in GNSS receivers. In one novel aspect, the ME tracking period, the ME interval, and the PE working period, the PE interval are dynamically determined based on the GNSS signal conditions and/or the user requirements. In one embodiment, acceptable provision estimated position fix are used. Estimated position result is generated at each GPS position interval if there is no position result generated by the PE working period. In another embodiment, the ME-tracking and/or the PE-working are adjusted to minimum operation needs by using ME-partial (MEP) and/or PE-partial (PEP). PEP is arranged aligned with MEP. In yet another embodiment, the PE working period is delayed such that the PE working period is aligned with the ME tracking period. The position result is generated based on a last epoch's measurement obtained in the previous ME tracking period.

Abstract translation: 提供了用于GNSS接收机节能的方法和装置。 在一个新颖的方面，ME跟踪周期，ME间隔和PE工作周期，PE间隔根据GNSS信号条件和/或用户要求动态确定。 在一个实施例中，使用可接受的提供估计位置定位。 如果PE工作期间没有产生位置结果，则在每个GPS位置间隔产生估计位置结果。 在另一个实施例中，通过使用ME部分（MEP）和/或PE部分（PEP）将ME跟踪和/或PE工作调整到最小操作需要。 PEP与MEP对齐。 在另一个实施例中，PE工作周期被延迟，使得PE工作周期与ME跟踪周期一致。 位置结果基于在之前的ME跟踪周期中获得的最后时期的测量而产生。
