  • Publication number: 20240340828
    Abstract: Example embodiments of the present disclosure relate to timing adjustment for uplink transmission, particularly in a high-speed scenario. A first device receives, from a second device, offset information indicating a difference in propagation delays between the first device and a third device experienced by the second device. The offset information is determined based on a time shifting value for a range of the difference in propagation delays. The time shifting value is associated with a switch from a beam associated with the first device to a beam associated with the third device. The third device is different from the first device. The first device transmits, to the second device, timing information indicating an amount of timing advance for transmission from the second device to the third device. The timing information is determined based on the time shifting value. Through this solution. UL transmission will be timing aligned.

  • Publication number: 20230126659
    Abstract: Methods, apparatuses, and computer program products for uplink (UL) timing advance (TA) adjustment at beam switch are provided. A method may include, when it is determined that beam change or transmission configuration indication (TCI) state switch should occur for beam(s) originating from non-collocated source nodes, enabling assistance information relating to time difference for a UE. The method may include preparing timing adjustment prediction model(s) configured to predict a timing advance adjustment (TAA) or actual TA that should be applied by the UE at the beam change, using the at least one prepared timing adjustment prediction model to determine the TAA or the actual TA that should be applied by the UE at the beam change. The method may include signaling or assigning the TAA or the actual TA to the UE, or using the TAA to adjust for a UE autonomously adjusted TA value at the beam change.

  • Patent number: 9501073
    Abstract: A method and voltage regulator comprises a generator that generates an error difference between a reference and regulated voltage. A clocked ADC samples the voltage as a digital stream. A DAC converts the stream to analog signal(s). A current source driven by the signal(s) generate(s) the regulated voltage. The generator may be an op-amp or comparator comprising a buffer and/or a latch. The N-bit ADC may be a ?-? modulator or N 1-bit ADC latches. The N-bit DAC may comprise 1-bit DACs comprising a switched-capacitor summer and a one stage RC LPF. Sampling the error up-converts flicker noise to the clock frequency which the DAC filters out. The current source may comprise N transistors with gates driven by a signal and sources tied to an independent power supply. Each signal may be weighted by a DAC weight. The apparatus may comprise a decoupling capacitor between the regulated voltage and ground.
