  • Publication number: 20200359207
    Abstract: Methods, systems, and devices for communications are described. A device or a group of devices may generate data. The group of devices may receive a group profile from a node that identifies the devices to be included, and the group profile may include a function to be evaluated at each of the devices. The node may also provision evaluation parameters which may allow the device to provide authenticated aggregate data to a requesting third party, without sharing the data between the devices, thus concurrently maintaining individual data privacy and data provenance.

  • Publication number: 20200358788
    Abstract: Methods, systems, and devices for wireless communications are described. Aspects include a device generating data to be sent to a receiving device and determining to provide provenance for the data. The device may generate a data identifier based on an identifier generation key and encrypt the data using an encryption key generated from a key associated with an owner of the device. The device may sign they encrypted data transmission using a signing key where the signing key is based on the encrypted data and the data identifier. In some cases, the device may send the data to a receiving device via one or more proxy devices. In some cases, multiple device may send signed data transmissions to a proxy device and the proxy device may process the multiple data transmission and send the processed data to the receiving device. The receiving device may verify provenance of the data.

  • Publication number: 20200356694
    Abstract: Methods, systems, and devices for wireless communications are described. Aspects may include receiving, at a device, a device configuration profile including one or more parameters for managing data transfers associated with a service and generating a transaction credential by which the data is to be associated in a storage. The transaction credential may be generated according to the configuration profile. Aspects may also include identifying, at the device, that data is to be stored in the storage that is associated with the service. Aspects include signing the data using the transaction credential and transmitting the signed data to the storage.

  • Patent number: 10742358
    Abstract: According to one aspect of the invention, a method is provided in which a control channel used for transmitting control information is partitioned into a plurality of subchannels each of which is operated at a specific data rate. For each of one or more user terminals, one of the subchannels is selected based on one or more selection criteria for transmitting control information from an access point to the respective user terminal. Control information is transmitted from the access point to a user terminal on a particular subchannel selected for the respective user terminal. At the user terminal, one or more subchannels are decoded to obtain control information designated for the user terminal.

  • Publication number: 20200067575
    Abstract: Spatial spreading is performed in a multi-antenna system to randomize an “effective” channel observed by a receiving entity for each transmitted data symbol block. For a MIMO system, at a transmitting entity, data is processed (e.g., encoded, interleaved, and modulated) to obtain ND data symbol blocks to be transmitted in NM transmission spans, where ND?1 and NM>1. The ND blocks are partitioned into NM data symbol subblocks, one subblock for each transmission span. A steering matrix is selected (e.g., in a deterministic or pseudo-random manner from among a set of L steering matrices, where L>1) for each subblock. Each data symbol subblock is spatially processed with the steering matrix selected for that subblock to obtain transmit symbols, which are further processed and transmitted via NT transmit antennas in one transmission span. The ND data symbol blocks are thus spatially processed with NM steering matrices and observe an ensemble of channels.

  • Patent number: 10382336
    Abstract: A method, operational at a network device, for conveying congestion information across different strata of a multi-strata network is provided. An indication is obtained that a congestion level for at least one of a radio access network node and a core network node of a network has changed. Consequently, a one or more service parameters for a plurality of services, operating at a service stratum, are updated or adjusted on a per service basis based on the congestion level indication. The one or more service parameters are provided or sent to, at least one of, a node operating at a service stratum or a user device that obtains services over the network.

  • Patent number: 9924511
    Abstract: Methods, systems, and devices are described for direct device-to-device (D2D) communications in a subframe on a channel in an unlicensed radio frequency spectrum band. A user equipment (UE) may perform a listen-before-talk (LBT) procedure on the channel in the unlicensed radio frequency spectrum band. The UE may identify a time period between a completion of the LBT procedure and a boundary of a second subframe. The UE may transmit a Wi-Fi preamble and a variable length message on the channel during the identified timer period. The variable length message may include a duration that is time aligned with the boundary of the second subframe.

  • Patent number: 9883486
    Abstract: Embodiments for bandwidth allocation methods, detecting interference with other systems, and/or redeploying in alternate bandwidth are described. Higher bandwidth channels may be deployed at channel boundaries (410), which are a subset of those for lower bandwidth channels (310), and may be restricted from overlapping. Interference may be detected (930) on primary, secondary, or a combination of channels, and may be detected in response to energy measurements (910) of the various channels. When interference is detected, a higher bandwidth Basic Service Set (BSS)(100) may be relocated to an alternate channel, or may have its bandwidth reduced to avoid interference. Interference may be detected based on energy measured on the primary or secondary channel, and/or a difference between the two. An FFT (1010) may be used in energy measurement in either or both of the primary and secondary channels. Stations may also monitor messages from alternate systems to make channel allocation decisions.

  • Patent number: 9867153
    Abstract: This application relates to wireless communication systems, and more particularly to distributed synchronization of “internet of everything” (IoE) devices to a common timing through opportunistic synchronization with user equipment (UE). Multiple IoE devices within proximity to each other establish device to device (D2D) links. When an IoE device receives an updated timing synchronization signal from a UE, the IoE device can broadcast the updated timing synchronization signal to other IoE devices directly or via a multi-hop forwarding scheme via the D2D links. Multiple groups of IoE devices can be synchronized to the same timing synchronization signal such that if and when IoE devices from the different groups come into proximity, the IoE devices will find each other and can merge into a larger group of synchronized IoE devices with minimal searching overhead and, therefore, minimal power consumption.
