Abstract: System for effecting a reversible sensory block includes a hybrid neuromodulator and hybrid lead for delivering electrical and pharmacological stimulation. An implantable modulator provides electrical pulse generation and pharmacological fluid infusion. Method for effecting a reversible sensory block delivers low-frequency stimulation based on the conduction velocity of a target afferent. Afferents with different conduction velocities may be blocked by stimulation with different frequencies. Temporally synchronized pulse stimuli from multiple stimulating electrodes may interfere with each other to stimulate a specific afferent. Spatial summation of synchronized low-frequency pulse stimulation may be delivered at multi-sites. Temporal interference of two kilohertz sinusoidal stimuli with slight frequency difference deliver a low-frequency sinusoidal stimulus at a focal region of interference. Spatial summation translates to evoked action potentials that converge at T-junction of a targeted afferent.

Abstract: Described is synchronization of radio units (RUs) with a reference time and frequency using a reference radio unit (reference RU) without the need for boundary-clock-based synchronization. A synchronized RU transmits a reference signal that is received at the reference RU and used to evaluate its time and frequency. A processing unit coupled to the reference RU evaluates waveform sample data, corresponding to the received signal, with reference waveform data and returns feedback, e.g., frequency error data, time error data, and quality information. The frequency error data and time error data are used to synchronize the RU. Messages between the DU and RU (e.g., via a fronthaul interface) indicate signal start time, stop time and frequency for transmitting by the RU, and for the RU to correct its time and frequency based on the error data. Messaging between the DU and the processing unit coordinates the reference waveform data for evaluation.

Abstract: The technology described herein is directed towards runtime dynamic downlink power configuration between a distributed unit and radio unit. In one O-RAN-compliant implementation, control-plane messages are used to update the downlink power without any service interruption, based on initialization information provided by management-plane messages to the distributed unit, including a radio unit's indication of support for the power change and the time (gap) needed by the radio unit to implement a power change. Based on this data, the distributed unit and radio unit (which are synchronized) change the downlink power at the same specific time (same symbol) such that the power configuration can be done during runtime without any service interruption. This is advantageous with power changes needed for Citizens Broadband Radio Service (CBRS) systems and/or for energy saving purposes, for example.

Example methods can calculate TDD pattern configurations for use in 5G and subsequent generation networks. TDD pattern configurations can be calculated based on traffic demand, which can be estimated based on data channel demands, control channel requirements, user equipment (UE) capabilities, UE radio frequency (RF) conditions, and/or target quality of service (QoS) levels. Time offsets between downlink (DL) and uplink (UL) transmissions can be adjusted to meet service latency requirements and hardware limitations.
