  • Publication number: 20240235691
    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support local light biasing for silicon photomultiplier (SiPM)-based photodetectors used in optical wireless communication (OWC). In a first aspect, a photodetector may include a silicon photomultipier (SiPM) having an input sensor configured to detect a light signal and an output interface configured to produce an output signal proportional to an intensity of the light signal detected at the input sensor, and a controllable light source positioned to emit a biasing light signal within a field of view of the input sensor, wherein the controllable light source is configured to emit the biasing light signal within a sensitivity range of the SiPM. When such photodetector is implemented in an OWC receiver, an analysis of the output signal allows the OWC receiver to adjust the biasing light at the controllable light source. Other aspects and features are also claimed and described.

  • Patent number: 9544942
    Abstract: A method and apparatus for radio resource control (RRC) state transitions of a user equipment (UE) are provided. For the RRC state transitions of the UE, for example, a reconfiguration message is received at the UE while the UE is in a cell dedicated channel (CELL_DCH) state of the RRC states. The reconfiguration message is configured to transition the UE from the CELL_DCH state to a non-dedicated channel state of RRC states. A plurality of acknowledgement procedures is sent on an uplink to the network, in response to the received reconfiguration message causing the UE to transition from the CELL_DCH state to the non-dedicated channel state.
