Abstract: An estimated location of an access point is generated based on identification of indoor and outdoor locations and the presumption that most access points are in an indoor location. The estimated location may be produced using location information for the access point and the identification of the indoor and outdoor locations while prioritizing the indoor location to produce the estimated location on or within a boundary of the indoor location. The location information may be, e.g., a preliminary estimated location or wireless signal measurements and associated position fixes for the access point. For example, a preliminary estimated location may be shifted to be on or within the nearest boundary of an indoor location or may be adjusted based on the location information. The estimated location may be calculated directly using weights to bias the calculation of the estimated location to be on or within the boundary of the indoor location.

Abstract translation: 基于室内和室外位置的识别以及大多数接入点在室内位置的推测来生成接入点的估计位置。 可以使用用于接入点的位置信息和室内和室外位置的识别来产生估计位置，同时优先考虑室内位置以在室内位置的边界上或内部产生估计位置。 位置信息可以是例如接入点的初步估计位置或无线信号测量和相关联的位置定位。 例如，初步估计位置可以被转移到或在室内位置的最近边界内，或者可以基于位置信息进行调整。 可以直接使用权重来计算估计位置，以将估计位置的计算偏置在室内位置的边界之内或之内。

Abstract: Techniques for publishing location information associated with a non-geotagged transceiver are disclosed. A method for publishing a position of a non-geotagged transceiver in a wireless communication system includes determining a first position of the non-geotagged transceiver based on a periodic neighbor list, determining a second position of the non-geotagged transceiver based on an accumulated neighbor list, determining if the first position and the second position agree, publishing a third position if the first position and the second position agree, such that the third position is determined based on the union of the periodic neighbor list and the accumulated neighbor list, and resetting the accumulated neighbor list if the first and second position do not agree.

Abstract: In one aspect, a method performed by an access point in a wireless local area network (WLAN), includes receiving a first ranging request message from a first device and monitoring for a second ranging request message from a second device on a channel of the WLAN. The first ranging request message includes a device identifier of the first device and the second ranging request message includes a device identifier of the second device. In response to receiving the second ranging request message, the access point combines the device identifier of the first device, first timing information associated with the first ranging request message, the device identifier of the second device, and second timing information associated with the second ranging request message into a single ranging response message. The access point then broadcasts the single ranging response message on the channel of the WLAN.
