    Abstract: Apparatus, methods, and computer-readable media for facilitating self-managed trust in Internet-of-Things networks are disclosed herein. An example method of trust management at a network manager includes enrolling a network endpoint with a network managed by the network manager. The example method also includes receiving trusted reference information for the network endpoint based on enrolling the network endpoint. Additionally, the example method includes performing verification of the network endpoint based on at least one of the trusted reference information or an attestation received from the network endpoint. Further, the example method includes enforcing policies to the network endpoint based on a result of the verification. Such trust management may improve privacy and security at the network, as well as reduce latency in responding to trust incidents.

    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 translation: 在多天线系统中执行空间扩展，以随机化接收实体针对每个发送的数据符号块观察到的“有效”信道。 对于MIMO系统，在发送实体处理（例如，编码，交织和调制）数据以获得要在NM传输跨度中发送的ND数据符号块，其中ND≥1和NM> 1。 ND块被划分为NM数据符号子块，每个传输跨度的一个子块。 对于每个子块，选择导向矩阵（例如，以确定性或伪随机方式从一组L个导引矩阵中，其中L> 1）。 每个数据符号子块用为该子块选择的导引矩阵进行空间处理，以获得在一个传输范围内经由NT个发射天线进一步处理和传输的发射符号。 因此，ND数据符号块用NM导引矩阵进行空间处理，并观察信道的集合。

    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.
