Abstract: Methods and apparatuses of providing positioning assistance data are disclosed. According to aspects of the present disclosure, a venue is partitioned into a plurality of tiles, with each tile represents an area of the venue. Measurements from each tile with respect to one or more access points in the venue may be represented as one or more images. The one or more images are then processed to generate a compressed positioning assistance data of the venue. The compressed positioning assistance data may then be provided to a mobile device. Position of a mobile device may be determined using the compressed positioning assistance data of the venue.

Abstract: Methods, devices, and systems are described for determining whether a mobile device is in a stopped state based at least in part on round trip time (RTT) measurements between the device and at least one access point. The stopped state determination may be based on RTT measurements alone, or on RTT measurements in combination with other positioning and movement measurements. Further, filtering such as particle and Kalman filtering may be used to improve determination of whether the device is in a stopped state.
Abstract translation: 描述了至少部分地基于设备和至少一个接入点之间的往返时间（RTT）测量来确定移动设备是否处于停止状态的方法，设备和系统。 停止状态确定可以仅基于RTT测量，或者基于与其他定位和移动测量结合的RTT测量。 此外，可以使用诸如粒子和卡尔曼滤波的滤波来改善装置是否处于停止状态的确定。
