    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.

    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.

    Abstract: Techniques for transmitting data using channel information for a subset of all subcarriers used for data transmission are described. A transmitter station receives channel information for at least one subcarrier that is a subset of multiple subcarriers used for data transmission. The channel information may include at least one transmit steering matrix, at least one set of eigenvectors, at least one channel response matrix, at least one channel covariance matrix, an unsteered pilot, or a steered pilot for the at least one subcarrier. The transmitter station obtains at least one transmit steering matrix for the at least one subcarrier from the channel information and determines a transmit steering matrix for each of the multiple subcarriers. The transmitter station performs transmit steering or beam-steering for each of the multiple subcarriers with the transmit steering matrix for that subcarrier.

    Abstract: This disclosure provides methods, components, devices, and systems for wireless communication. Some aspects more specifically relate to dynamic path selection for wireless connectivity. An access point (AP) may receive communication link information and device status information from cellular-enabled devices in a wireless local area network (WLAN). The communication link information may indicate path metrics (such as link quality information) associated with respective connections between the cellular-enabled devices and a communication network (such as the Internet). The device status information may indicate operational metrics associated with the cellular-enabled devices (such as battery status information or cellular subscription information). If, for example, the performance of a default connection between the AP and the communication network deteriorates, the AP may select one of the cellular-enabled devices to relay wireless communications between the communication network and the AP in accordance with the communication link information and the device status information.

    Abstract: This disclosure provides systems, methods and apparatuses for intelligent cloud-edge resource management. An end device may provide edge nodes of an edge computing system with network link information, which may enable the edge nodes to schedule and distribute task workloads more effectively, providing greater performance, power, security, and mission-critical network availability. For example, if the end device transmits a processing task request to a first edge node, the first edge node may assign the processing task to a second edge node according to the network link information. Additionally, or alternatively, the end device may transmit an indication of processing task parameters to one or more edge nodes and may receive an indication of an estimated completion time of the processing task from the one or more edge nodes. Accordingly, the end device may assign the processing task to an edge node with the lowest completion time.
