Abstract: A communication system performs wireless communication using electromagnetic field coupling between a transmission coupler and a reception coupler and moves at least one of the transmission coupler and the reception coupler so as to change the position in a predetermined direction of the reception coupler relative to the transmission coupler. In the communication system, the greater the distance between an overlap portion where the transmission coupler and the reception coupler overlap as viewed from a vertical direction to the predetermined direction and an input end of the transmission coupler is, the higher the degree of coupling between the transmission coupler and the reception coupler becomes.
Abstract: Apparatuses, methods, and systems are disclosed for determining a maximum power reduction for non-contiguous radio resource allocations. One apparatus includes a processor that receives a non-contiguous resource allocation and calculates a fraction of resource block punctured from a smallest containing contiguous allocation (“SCCA”). Here, the SCCA is the smallest set of contiguous resource blocks that encompasses the non-contiguous resource allocation. The processor determines a first additional maximum power reduction for the non-contiguous resource allocation in response to the fraction of punctured resource blocks being less than a threshold value. The apparatus includes a transceiver that transmits an uplink signal on the non-contiguous resource allocation using the first additional maximum power reduction in response to the fraction of punctured resource blocks being less than the threshold value.
Abstract: Channel predictive behavior and fault analysis may be provided. A forward time value may be determined comprising a time a forward signal takes to travel from a transmitter over a channel to the receiver. Next, a reflected time value may be determined comprising a time a reflected signal takes to travel to the receiver. The reflected signal may be associated with the forward signal. A discontinuity may then be determined to exist on the channel based on the forward time value and the reflected time value. The reflected signal may be caused by the discontinuity and a high impedance or low impedance at the transmitter present after the forward signal is sent.

Abstract: Techniques are provided for lazy push optimization, allowing for constant time push operations. A d-heap is used as the underlying data structure for indexing values being inserted. The d-heap is vectorized by storing values in a contiguous memory array. Heapify operations are delayed until a retrieve operation occurs, improving insert performance of vectorized d-heaps that use horizontal aggregation SIMD instructions at the cost of slightly lower retrieve performance.
