    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.

    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.

    CPC classification number: H04W74/0808

    Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may perform a first transmission to one or more receiving devices, the first transmission associated with a transmission type. The transmitting device may determine a feedback response for the first transmission based on monitoring for feedback messages from the one or more receiving devices in response to the first transmission. The transmitting device may select a contention window size for performing one or more subsequent transmissions based at least in part on the feedback response and the transmission type. The transmitting device may perform the one or more subsequent transmissions in accordance with a clear channel assessment procedure using the selected contention window size.

    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support configured reception with sidelink control information (SCI) repetition over a sidelink. In aspects, a receiving user equipment (UE) may be configured to conduct combined reception/decoding of SCI repetitions (received from a transmitting UE over a sidelink) over multiple time-frequency slots at pre-defined occasions (e.g., occasions configured by a base station) to decode a sidelink transmission. In aspects, a receiving UE may receive from a transmitting UE over a sidelink, a sidelink transmission during a reception occasion that includes a plurality of reception opportunities for the receiving UE. Each reception opportunity of the plurality of reception opportunities includes a repetition of an SCI. The receiving UE decodes the SCI by combining the repetitions of the SCI received in one or more reception opportunities, and decodes a data transmission (e.g., a physical sidelink shared channel (PSSCH) transmission) using the decoded SCI.

    Abstract: This disclosure provides systems, methods and apparatuses for indicating sidelink processes for sidelink feedback. A second user equipment (UE) may request hybrid automatic repeat request (HARD) responses from a first UE for a particular set of sidelink processes over a physical sidelink feedback channel. To indicate multiple sidelink processes, the second UE may indicate, in sidelink control information, a window of sidelink processes. The window may be a sliding window that starts with a starting sidelink process and extends through other sidelink processes. The second UE may transmit data for the sidelink processes in the sliding window and receive feedback for the indicated sidelink processes. In some aspects, the first UE may select, in coordination with the second UE, the sidelink processes for which feedback is to be provided.
