  • Publication number: 20230344563
    Abstract: In an example, a first User Equipment (UE) receives a sidelink transmission, associated with enabled sidelink Hybrid Automatic Repeat Request (HARQ) feedback, from a second UE in a first timing. The first UE attempts to access a channel for transmission of a sidelink HARQ feedback in a first feedback resource in a second timing. The sidelink HARQ feedback is in response to the sidelink transmission. The attempt to access the channel for the transmission of the sidelink HARQ feedback in the first feedback resource fails. The first UE performs channel access for a second feedback resource. The second feedback resource is within a window and/or within a predefined duration of the first timing or the second timing. In response to successfully performing the channel access, the first UE performs, in the second feedback resource, a sidelink feedback transmission of the sidelink HARQ feedback to the second UE.

  • Publication number: 20230327676
    Abstract: Systems and methods reduce a locking time of a type-II all-digital phase-locked loop (ADPLL) circuit by performing steps that comprise receiving a reference signal having a reference frequency and setting a digitally controlled oscillator (DCO) to a target frequency greater than the reference frequency. The DCO generates an output signal that is used to generate a feedback signal. A time-to-digital converter is used to determine an initial phase difference between the reference signal and the feedback signal, and a digital initial phase compensation circuit adjusts the initial phase difference to a substantially zero phase difference to reduce the locking time of the ADPLL circuit such that the ADPLL circuit reaches a steady-state condition in ten or fewer cycles of the reference signal.
