Abstract: A communication system includes a transmitter, one or more active scattering platforms, and one or more remote receivers. The transmitter includes a beam forming network for transforming M signals into a set of shaped beams which are radiated toward the active scattering platforms by transmitter antenna elements. The active scattering platforms receive and re-radiate one or more of the radiated shaped beams toward the receivers. The beam forming network optimizes composite transfer functions under performance constraints. Each composite transfer function is a linear combination of transfer functions. Each transfer function characterizes propagation paths from one transmitter antenna element to one receiving antenna element. Each receiving antenna element is identified by a user element identification index in the transfer functions. Each receiver is identified by a user identification index.

Abstract: In some embodiments, a user equipment (UE) and base station implement improved communication methods which enable a UE that is peak current limited to perform UL transmissions which are consistent with the UL timeline. Embodiments are also presented which enable a UE that is peak current limited to utilize a new form of distributed TTI (transmit time interval) bundling for improved uplink communication performance. In performing “distributed” TTI bundling, the UE may transmit a plurality of redundancy versions of first information to the base station, wherein the plurality of redundancy versions are transmitted in non-consecutive sub-frames with a periodicity of X ms. After the plurality of redundancy versions of first information are transmitted to the base station, the base station may provide a single acknowledge/negative acknowledge (ACK/NACK) to the UE. A method for dynamically generating and using a bundle size for TTI bundling is also disclosed.

Abstract: The system and method of the present disclosure relates to technology for monitoring a broadcast device that is non-network connected. A wireless device monitors for a broadcast message transmitted wirelessly by the broadcast device. Upon discovery of the broadcast message, the wireless device transmits information from the broadcast message to a remotely located sever via a network. The server stores the broadcast information and determines the status (e.g., online or offline) of the broadcast device. The status is determined based on the detection time (e.g., the last seen time of the broadcast device by the wireless device) and an offline threshold value (e.g., a predetermined time period) that is compared to the current time or time upon which the server received the broadcast information. As a result of the comparison, the server determines whether the broadcast device is online or offline.
