Abstract: A base station may generate and transmit a transport stream including a sequence of frames. A frame may include a plurality of partitions, where each partition includes a corresponding set of OFDM symbols. For each partition, the OFDM symbols in that partition may have a corresponding cyclic prefix size and a corresponding FFT size, allowing different partitions to be targeted for different collections of user devices, e.g., user devices having different expected values of maximum delay spread and/or different ranges of mobility. The base station may also dynamically re-configure the sample rate of each frame, allowing further resolution in control of subcarrier spacing. By allowing the cyclic prefixes of different OFDM symbols to have different lengths, it is feasible to construct a frame that confirms to a set payload duration and has arbitrary values of cyclic prefix size per partition and FFT size per partition. The partitions may be multiplexed in time and/or frequency.

Abstract: Systems and methods for remote therapy and patient monitoring are provided. A method comprises contacting an outer skin surface of a patient with a contact surface of a stimulator and transmitting an electrical impulse from the stimulator transcutaneously through the outer skin surface to a nerve within the patient. Data related to parameters of the electrical impulse applied to the nerve is stored and transmitted to a remote source. The data may include duration of treatment, amplitude of the electrical impulse, compliance with a prescribed therapy regimen or other relevant data related to the therapy. The method may further include collecting patient status data, such as symptoms of a medical condition (e.g., severity of a headache) before, during and/or after stimulation. The patient status data is correlated with the treatment data to monitor compliance and/or the effectiveness of the therapy.
