    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 MAC processing for efficient use of high throughput systems that may be backward compatible with various types of legacy systems are disclosed. In one aspect, a data frame is formed comprising a common portion for transmission in a format receivable by various stations, such as access points and remote stations. The data frame also comprises a dedicated portion, formatted for transmission to a specified remote station. In another aspect, the common portion is unsteered, and the dedicated portion is steered. In another aspect, an access point schedules an allocation in response to a data indication included in a common portion of a data frame transmitted from one remote station to another. In another aspect, a first station transmits a reference to a second station, which measures the reference and generates feedback therefrom.

    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.
