This disclosure provides methods, components, devices, and systems for sounding for trigger-based ranging. Some aspects more specifically relate to a first wireless device dividing a frequency bandwidth available for ranging procedures into a plurality of subbands in accordance with orthogonal frequency-division multiple access (OFDMA) techniques. In some implementations, the first wireless device may transmit a trigger frame that assigns a subband to a respective neighbor wireless device. Each respective neighbor wireless device may transmit, during a same time occasion, a respective sounding signal via each respective subband allocated to the respective neighbor wireless device. In some implementations, the first wireless device may perform sounding procedures using combined multiple input multiple output (MIMO) and OFDMA techniques, where each neighbor wireless device may be assigned a respective spatial stream. Accordingly, the first wireless device may support sounding procedures for larger quantities of neighbor wireless devices.

Sounding for trigger-based ranging

A technique involves modular storage of network service plan components and provisioning of same. A subset of the capabilities of a service design system can be granted to a sandbox system to enable customization of service plan offerings or other controls.

Service design center for device assisted services

This disclosure provides methods, devices, and systems for performing passive scanning operations on one or more wireless channels. In some implementations, a wireless communication device configures an off-channel scan time and a passive scanning period for passive scanning operations based on latency requirements of a low-latency application, and selects a home channel dwell time for the passive scanning operations. The wireless communication device may perform the passive scanning operation by alternating between listening for beacon frames on one or more second wireless channels for the configured off-channel scan time and dwelling on a home channel for the selected home channel dwell time during a first portion of the configured scanning period. The wireless communication device also may listen for beacon frames on the one or more second wireless channels during a second portion of the configured scanning period that is defined by the selected home channel dwell time.

Mirrored split passive scanning

Disclosed herein are various embodiments for publishing a service offer set to a device agent on an end-user device and for on-device selection of a service. In some embodiments, a network system publishes a service offer set to an end-user device over a wireless access network, receives an offer set user selection from the end-user device, and provisions one or more network functions based on the offer set user selection.

Service selection set publishing to device agent with on-device service selection

This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for high efficiency (HE) beacons. HE supported access points (APs) and stations (STAs) may operate on resource deployments used for Wi-Fi technology and without support for legacy devices, also referred to as a greenfield deployment. An AP may identify updated capability information and transmit a HE physical layer convergence protocol (PLCP) protocol data unit (PPDU) including a beacon frame. A STA may receive, from the AP, the HE or EHT PPDU and identify an indication of change to a content or format of the beacon frame relative to a reference beacon frame. Based on the identified indication, the STA may then determine an updated content or format for the beacon frame and process the beacon frame or skip processing for one or more portions of the beacon frame.

High efficiency signaling

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for radio frequency (RF) sensing in the millimeter-wave frequency spectrum that can be performed over multiple phases. During a session setup phase, a radar initiator identifies one or more wireless stations (STAs) that are capable of radar ranging and sets up a radar measurement session that includes at least one of the identified STAs. During a measurement negotiation phase, the radar initiator performs a respective beamforming training operation with each STA and indicates, to each STA, one or more parameters associated with the radar measurement session. During a radar measurement phase, the radar initiator transmits radar setup information to, and receives ranging information from, each STA. In some aspects, the radar initiator may perform an object detection operation that indicates a location of an object associated with the ranging information received from each radar STA.

Radar-based radio frequency (RF) sensing

Secure device data records (DDRs) are provided. In some embodiments, a system for secure DDRs includes a processor of a wireless communication device for wireless communication with a wireless network, in which the processor is configured with a secure execution environment, and in which the secure execution environment is configured to: monitor service usage of the wireless communication device with the wireless network; and generate a plurality of device data records of the monitored service usage of the wireless communication device with the wireless network, in which each device data record is associated with a unique sequence order identifier; and a memory coupled to the processor and configured to provide the processor with instructions. In some embodiments, the secure execution environment is located in an application processor, in a modem processor, and/or in a subscriber identity module (SIM).

Communications device with secure data path processing agents

Wireless offloading provides tools to a service provider to encourage or direct a subscriber to offload from a first network, e.g., a cellular network, to a second network, e.g., a Wi-Fi network. The cellular service provider can use network data to determine wireless offloading priorities for cellular subscribers on an individual or group basis. The cellular service provider may use wireless network data it has and/or wireless network data it learns about networks from the wireless devices (which may obtain Wi-Fi network data from beacon frames of Wi-Fi networks or active scanning and which may report to the cellular service provider). Each wireless device can be given scanning assignments to ensure that the reporting task is shared among subscribers or adjusted to fill in gaps in data. With the network data, the cellular service provider is capable of generating useful prioritized network lists for wireless devices, either individually or as a group. Preferences can be encouraged in the form of incentive offers to subscribers to, e.g., offload from the cellular network to a Wi-Fi network. Incentive offers can include offers to lower service costs or provide additional or improved services.

System and method for wireless network offloading

Methods, systems, and devices for wireless communications are described. In some aspects, two devices may support signaling and messaging designs that support bandwidths that are greater than 160 MHz for ranging null data packets (NDPs). For example, various signaling and messaging designs may support a use of a 320 MHz bandwidth for ranging NDPs as part of a ranging measurement procedure, which may offer greater resolution than narrower bandwidths. The signaling and messaging designs may include one or more updates for a null data packet announcement (NDPA) frame, for a trigger frame, for session negation messages (such as one or both of an initial fine timing measurement (IFTM) frame and an IFTM request (IFTMR) frame), for segmentation techniques for ranging NDPs, or for any combination thereof.

Techniques for wide bandwidth positioning in a wireless local area network

This disclosure provides methods, devices and systems for generating a secure long training field (LTF). In some implementations, the secure LTF may include a randomized bit sequence that is difficult, if not impossible, to replicate by any device other than the transmitting device and the intended receiving device. For example, the transmitting device may use a block cipher or stream cipher to generate a pseudorandom bit sequence and may select a subset of bits of the pseudorandom bit sequence to be mapped to a sequence of modulation symbols representing an LTF symbol of the secure LTF. More specifically, each of the modulation symbols is mapped to a respective one of a number of subcarriers spanning a bandwidth of the secure LTF. The transmitting device may further transmit a physical layer convergence protocol (PLCP) protocol data unit (PPDU) that includes the secure LTF to the receiving device.

Secure long training field (LTF)

Enterprise and consumer billing allocation for wireless communication device service usage activities is provided. In some embodiments, enterprise and consumer billing allocation for wireless communication device service usage activities includes monitoring a service usage activity of a wireless communication device, and determining an enterprise and consumer billing allocation for the monitored service usage activity. In some embodiments, enterprise and consumer billing allocation for wireless communication device service usage activities includes monitoring a service usage activity of a wireless communication device, and reporting the monitored service usage activity to a network element, in which the network element determines an enterprise and consumer billing allocation for the monitored service usage activity. In some embodiments, enterprise and consumer billing allocation for wireless communication device service usage activities includes providing a service design center for configuring an enterprise and consumer billing allocation of monitored service usage activities for a plurality of wireless communication devices associated with an enterprise account, and implementing the configured enterprise and consumer billing allocation for monitored service usage activities for the plurality of wireless communication devices associated with the enterprise account.

Enterprise access control and accounting allocation for access networks

Device Assisted Services (DAS) for protecting network capacity is provided. In some embodiments, DAS for protecting network capacity includes monitoring a network service usage activity of the communications device in network communication; classifying the network service usage activity for differential network access control for protecting network capacity; and associating the network service usage activity with a network service usage control policy based on a classification of the network service usage activity to facilitate differential network access control for protecting network capacity.

Device-assisted services for protecting network capacity

There is provided a wireless end-user device configured to assign one of classifications to each of end-user applications to allow for a differential network access control of the end-user applications. The classifications include a background classification and a foreground classification. The differential network access control includes a service usage control policies applicable when a network service is available via a wireless modem, the service usage control policies including a first policy that allows data associated with a first end-user application of the end-user applications to be communicated via the wireless modem, and a second policy that defers the data associated with the first end-user application to be communicated via the wireless modem until a state change occurs. The wireless end-user device is configured to dynamically select from the service usage control policies based on whether the background classification or the foreground classification is assigned to the first end-user application.

Methods, systems, and devices for wireless communications are described. A station (STA) may receive a null data packet (NDP) on a plurality of subcarriers, and the STA may generate a channel state information (CSI) matrix for each subcarrier of the plurality of subcarriers. After generating a CSI matrix for a subcarrier, such as at least one subcarrier, the STA may scale each value in the CSI matrix using a power-of-two value to minimize complexity. Specifically, instead of scaling each value in the CSI matrix to a value between zero and one using divisions (for example, which may be computationally expensive), the STA may use shifting to scale each value in the CSI matrix. The STA may then quantize the scaled values in the CSI matrix for reporting, and the STA may transmit the quantized, scaled values in the CSI matrix in a CSI report.

Scaling and quantization for channel state information reporting

This disclosure provides methods, devices and systems for radio frequency (RF) sensing in wireless communication systems. In some implementations, a transmitter device transmits sounding sequences configured for channel estimation over a wireless channel to a receiver device. The transmitter device also transmits or receives non-sounding frames associated with a channel report of the receiver device. The transmitter device transmits a frame soliciting the channel report from the receiver device. The transmitter device receives the channel report, which may include channel state information (CSI) of the wireless channel responsive to at least the sounding sequences. Some types of channel reports may take longer to generate than other types of channel reports. Transmitting or receiving the non-sounding frames during the time period may prevent other devices from accessing the wireless channel when the receiver device needs additional time to generate a certain type of channel report.
