  • Publication number: 20250151095
    Abstract: Various aspects of the present disclosure relate to a user equipment (UE) that acquires, from a base station, a sidelink (SL) grant that includes a channel occupancy time (COT) for part of an unlicensed spectrum allowing the acquiring UE to transmit SL control and data information to a secondary UE. The acquiring UE can also share the COT with the secondary UE, allowing the secondary UE to transmit SL control and data to the acquiring UE or another UE. The acquiring UE performs clear channel assessment (CCA) on one or more SL resources associated with the SL grant. The UE returns an SL hybrid automatic repeat request (HARQ) feedback to the base station based at least in part on a status of the CCA.

  • Publication number: 20250150148
    Abstract: Various aspects of the present disclosure relate to a user equipment (UE) that performs beam management while in a radio resource control inactive (RRC_INACTIVE) state. In one or more implementations, while in the RRC_INACTIVE state, the UE triggers generation of beam information for a base station. This beam information indicates a new serving beam on which, for example, a paging message is to be received from the base station. The UE generates and transmits the beam information to the base station.

  • Publication number: 20250150918
    Abstract: Various aspects of the present disclosure relate to a user equipment (UE) that detects, while in a radio resource control inactive state and optionally while in a small data transmission session, that beam information is to be reported to a base station. This detection is performed based on some criteria, such as the current (serving) downlink beam quality dropping below a threshold amount. In response to detecting that beam information is to be reported to the base station, the UE initiates a random access procedure in order to provide the beam information (e.g., one or more candidate beams to switch to) to the base station. This beam information notifies the base station to change to a new serving beam due to, for example, the quality of the current serving beam dropping because of movement of the UE, blockages between the UE and the base station, and so forth.

  • Publication number: 20250151069
    Abstract: Various aspects of the present disclosure relate to a user equipment (UE) that maintains a set of skipping durations that includes multiple subsets of skipping durations. The base station transmits to the UE a first control signaling indicating to activate one of the subsets of skipping durations. At a subsequent time, the base station transmits to the UE a second control signaling indicating that the UE can skip physical downlink control channel (PDCCH) monitoring in some time resources (e.g., slots). The second control signaling includes an identifier of a skipping duration and the UE selects the identified skipping duration in the active subset of skipping duration values. The UE then skips or terminates monitoring of the PDCCH for the selected skipping duration.

  • Patent number: 12293014
    Abstract: An information processing apparatus includes a processor that processes the image data of the image stored in a memory in order to detect a face area with a face captured therein and an orientation of the face from the image, and controls the screen brightness of a display unit based on the orientation of the face detected by the processing. When the detected face orientation falls within a preset first angle range, the processor determines that the face orientation is a first orientation, and even when the detected face orientation is out of the first angle range, the processor determines that the face orientation is the first orientation depending on the amount of change in the detected orientation of the face changing in a direction of the first orientation.
