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.

Methods and apparatus for enhanced WiFi positioning using civic location for 4G and 5G

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.

Ranging protocol improvements to support antenna switching

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.

Reducing re-association time for STA connected to AP

In a wireless network, a first wireless device may send a first frame instructing a second wireless device to suspend a block acknowledgement session while the first wireless device is facilitating a Bluetooth operation. When the Bluetooth operation is complete, the first wireless device may send a second frame instructing the second wireless device to resume the block acknowledgement session.
