    Abstract: A method and apparatus for re-associating a station (STA) to an access point (AP). The STA sends a re-association request to the AP to initiate a re-association process with the AP. The re-association request indicates that a handshake operation is to be bypassed during the re-association process. The STA receives a re-association response from the AP in response to the re-association request and, upon receiving the re-association response, enables data communications with the AP using a set of preexisting cryptographic keys. For example, the set of preexisting cryptographic keys may be negotiated with the AP during at least one of a prior association process or a prior re-association process.

    Abstract translation: 一种用于将站（STA）重新关联到接入点（AP）的方法和装置。 STA向AP发送重新关联请求，以发起与AP的重新关联过程。 重新关联请求指示在重新关联过程期间绕过握手操作。 STA响应于重新关联请求从AP接收重新关联响应，并且在接收到重新关联响应时，使得能够使用一组预先存在的加密密钥与AP进行数据通信。 例如，在先前的关联过程或先前的重新关联过程中的至少一个中，可以与AP协商一组预先存在的加密密钥。

    Abstract: This disclosure provides systems, methods and apparatuses, including computer programs encoded on computer storage media, for ranging procedures performed using antenna switching. In one aspect, a device initiating a ranging procedure may transmit a ranging request, which may include antenna switching capabilities of the initiating device, a request for antenna switching by a responding device during the ranging procedure, or both. Ranging signaling may be communicated between the initiating device and the responding device using different transmit antennas, receive antennas, or both. In some implementations, ranging messages transmitted by the responding device may include transmit antenna indices used for transmission of different ranging messages, and receive antenna indices used for reception of different ranging response messages. The initiating device may estimate a range relative to the responding device based on round trip times (RTTs) associated with different antenna pairs used during the ranging procedure.

    Abstract: Disclosed are techniques for positioning. In an aspect, a positioning entity obtains a plurality of pairs of timing measurements based on a plurality of pairs of ranging messages exchanged on a plurality of bandwidths, determines a plurality of range measurements based on the plurality of pairs of timing measurements, each range measurement of the plurality of range measurements based on one pair of the plurality of pairs of timing measurements, determines a weight for each range measurement of the plurality of range measurements based at least on a bandwidth of the plurality of bandwidths of a pair of timing measurements of the plurality of pairs of timing measurements used to determine the range measurement, and determines a weighted mean of the plurality of range measurements based at least on the plurality of range measurements and weights of the plurality of range measurements.

    Abstract: During positioning of a user equipment (UE), for example, during an emergency call, a civic location of the UE may be determined. For example, during a location session in a wireless network, a UE may detect a WiFi access point (AP) and obtain the civic location of the WiFi AP from the AP. The UE may provide the civic location to a location server in the wireless network, which may treat the civic location as the civic location of the UE. The location server may validate the civic location using a geodetic location, e.g., obtained based on measurements from a satellite positioning system and/or base stations in the wireless network. The location server may further verify that the UE is proximate to the WiFi AP using WiFi positioning measurements performed by the UE. The validated civic location can be provided to an external client, e.g. a PSAP.
