Abstract: Embodiments are disclosed for address changing schemes in a wireless communications system. Some embodiments include an access point (AP) that can establish two or more address profiles with a station (STA), establish a schedule for switching from a first address profile to a second address profile, where the first and second address profiles are of the two or more address profiles, and transmit a first data transmission using the first address profile. Some embodiments include switching from the first address profile to the second address profile based on the schedule, and transmitting a second data transmission using the second address profile. The schedule can be based on a randomized time synchronization function (TSF). The AP can establish a joint algorithm with the STA, and use the joint algorithm determine the first and the second address profiles as well as transition times for the schedule.

Abstract: A device observes base station signals and identifies those that are suspicious and those that are normal. The device avoids communication with the sources of suspicious signals. A rogue base station may be the source of suspicious signals. A system operated by a mobile network operator is a source of normal signals. A rogue operator and the mobile network operator have different goals and those differences are the basis of embodiments provided herein to detect the rogue base station. The observations are characterized by message rates, waveform accuracy, cell parameters, and synchronization level.

Abstract: This Application describes mechanisms to transfer cellular service plans and associated credentials efficiently between wireless devices. Information regarding transferability of cellular services for SIMs/eSIMs to a wireless device are obtained from locally stored or remotely accessible cellular service information and/or associated mobile network operator (MNO) information. Access to network-based servers to determine transferability and/or to effect transfer can use non-cellular connections when available. Transferability information can be presented to a user to narrow selection of cellular service plans to transfer.

Abstract: A wireless device determines a location, identifies a mobile network operator (MNO), and/or experiences a network event. In some instances, the wireless device recognizes a base station as being operated by the MNO. Based on the location, the MNO and/or the network event, the wireless device determines a security action. The security action can include one or more of: (i) ignoring a network command associated with the network event, (ii) providing an alert notification via a user interface of the wireless device alerting a user of a security risk associated with the location, MNO, and/or network event, or (iii) ignoring communication from the base station temporarily or for an indefinite period of time. In some instances, the security action includes proceeding with normal communication with the base station at the location using network services of the MNO.

Abstract: Embodiments are disclosed for encrypting media access control (MAC) Header fields for Wireless LAN (WLAN) privacy enhancement. For example, a transceiver of a station (STA) or an access point (AP) can set a real time Media Access Control (MAC) header bit in a payload of an aggregated MAC Protocol Data Unit (A-MPDU) subframe to an actual value of a power management (PM) field of a MAC header of the A-MPDU subframe. The transceiver can encrypt the payload, set the PM field to an over the air (OTA) PM value, and transmit the A-MPDU subframe over the air. The OTA PM value can include all zeros, a predetermined value, or a randomized value The transceiver can also set static MAC header bits in the payload of the A-MPDU subframe to corresponding actual values of an aggregated MAC service data unit (A-MSDU) present field of the A-MPDU subframe.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing address and parameter modifications for an access point (AP) and/or a station (STA). Some aspects of this disclosure relate to an electronic device. The electronic device includes a transceiver and a processor communicatively coupled to the transceiver. The processor is configured to communicate, using the transceiver, with a second electronic device that is associated with the electronic device using a first address and a first parameter of the electronic device. The processor is further configured to determine a second address and a second parameter for the electronic device, where the second address is different from the first address and the second parameter is different from the first parameter. The processor is further configured to communicate with the second electronic device using the second address and the second parameter.

Abstract: Embodiments are disclosed for station (STA) identifier opt-in. Some embodiments include a STA that can associate with an access point (AP) of a wireless network, where the STA is configured to opt-in to being identified by the AP. The STA can transmit a first message 2 (M2) of a 4-way handshake protocol during the association, where the first M2 includes a Device Identifier (ID) Key Data Encapsulation (KDE) that includes an Opt-in Control field, where a first value of the Opt-in Control field indicates the STA opts-in to being identified by the AP. The STA can receive a first message 3 (M3) of the 4-way handshake protocol including a Device ID KDE and an ID Blob, where the ID Blob corresponds to the STA. The STA can communicate with the AP, where the first value enables the AP to collect data about the STA during the communication.

Abstract: Embodiments are disclosed for address changing schemes for a multi-link device in a wireless communications system. Some embodiments include a privacy enhanced (PE) access point (AP) multi-link device (MLD) that includes one or more affiliated APs operating on different links. The PE AP MLD can generate a first randomized OTA MLD address based at least on the MLD address of the PE AP MLD for a first affiliated PE AP (PE AP1). The PE AP MLD can transmit a first data transmission using the first OTA MLD address where the first data transmission includes an encrypted aggregated MAC service data unit (A-MSDU) subframe that includes the MLD address. The PE AP MLD can correlate the MLD address of the PE AP MPL with multiple addresses comprising: the first OTA MLD, a unique MLD address, and a Media Access Control (MAC) service access point (SAP) MLD address.

Abstract: A user of a device desires that geographic position information of the device be kept private. A network may track a geographic position of a device using timing advance (TA) data and also a passive attacker may attempt to track the geographic position of the device by observing base station TA commands. In embodiments provided herein, a device diminishes or obfuscates geographic position information by using a timing change value while not disturbing synchronization of uplink signals from multiple devices arriving at a base station. To resist an averaging solution by an observer, the device in some embodiments adjusts the timing change value based on an internal timer. In an emergency call situation, the method permits the base station to obtain geographic position information based on TA procedures.
