    Abstract: Certain aspects of the present disclosure provide techniques for communicating and scheduling communications over sidelink. Certain aspects of the disclosure relate to a method for wireless communication by a user equipment (UE). In some examples, the method includes transmitting, to one or more other UEs, first control information comprising an indicator of a starting time and a duration of a first time interval for communication of a first data transmission over a sidelink, wherein the first time interval comprises one or more time periods of a first time window. In some examples, the method includes transmitting the first data transmission to at least one of the one or more other UEs during the first time interval.

    Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving a configuration message indicating a group common control resource allocated to a set of UEs that includes the UE, identifying a hashing function assigned to the UE for detecting control messaging communicated via the group common control resource that is addressed to the UE, receiving, via the group common control resource, a control message indicating addressing data and a bitmap, and processing the addressing data using the hashing function and the bitmap to determine applicability of the control message to the UE.

    CPC classification number: H04W72/1268

    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) and a network entity may support one or more mechanisms according to which the UE and the network entity may avoid glitches in latency-sensitive traffic and reduce ambiguity relating to scheduling and resource use expectations for configured grant (CG) periods including multiple shared channel occasions. Such mechanisms may include a rule according to which the UE and the network entity expect spans of shared channel occasions within different CG periods to avoid overlapping in time. The rule may preclude any time domain overlapping between spans of shared channel occasions within different CG periods or may allow for a time domain overlapping between spans of shared channel occasions within different CG periods and instead indicate how a UE is expected to use shared channel occasions of overlapping spans of shared channel occasions.

    Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a second UE, a control message that indicates a duration of time the second UE has reserved at least a first subchannel of a first subband of a set of shared spectrum subbands. The duration of time may include a quantity of time periods. The first UE may transmit, during a time period of the quantity of time periods and in a second subchannel of the first subband, a power reservation signal that indicates a transmission power associated with the first UE beginning transmission to a third UE in a second subband of the set of shared spectrum subbands and partway through the time period. The first UE may transmit signaling to the third UE in the second subband partway through the time period and after transmitting the power reservation signal.

    Abstract: Methods, systems, and devices for wireless communication are described. In some examples, an energy transfer device may indicate timing information for backscattering a signal. The energy transfer device may transmit, to an energy harvesting device, a message including timing information that indicates when the energy harvesting device is to begin backscattering of a wireless signal. The energy transfer device may transmit the wireless signal. The energy harvesting device may monitor for and receive the wireless signal based on the message. The energy harvesting device may transmit a backscattered signal based on application of a backscattering function to the wireless signal in accordance with the timing information.

    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.
