    Abstract: A unified frame structure for communicating in a synchronous and slotted mesh network is provided. Nodes within the mesh network are designated as primary and secondary nodes. For each transmission, a primary node may first send scheduling information to secondary nodes associated with the primary node. The receiver of the scheduled link may send a clear-to-send signal. For uplink scheduled transmissions, the receiver is the primary node. For downlink scheduled transmissions, the receiver is a secondary node. The transmitter of the scheduled link may receive the CTS signal from one or more proximate receivers, including a receiver associated with the scheduled transmission as well as other receivers not associated with the scheduled transmission. The transmitter of the scheduled link may estimate the signal to interference-plus-noise ratio of other links that are of higher priority and may then determine whether to yield or power back off the scheduled transmission.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a configuration indicating multicast broadcast single frequency network (MBSFN) subframes within a radio frame. The configuration indicates a number of symbols of an MBSFN subframe for receiving a wide area network (WAN) control signal and remaining symbols of the MBSFN subframe dedicated for peer-to-peer communication. The apparatus communicates with a peer via the symbols dedicated for peer-to-peer communication. Alternatively, the apparatus receives a configuration indicating a portion at a beginning and/or end of a guard period of a special time division duplex (TDD) subframe. The portion is reserved for an uplink timing advance and/or switching from transmission to reception and/or reception to transmission. The configuration also indicates a remaining portion of the guard period of the special TDD subframe for peer-to-peer communication. The apparatus communicates with a peer via the remaining portion.

    Abstract: Methods, systems, and devices for wireless communications that support inter-user equipment (UE) coordination (IUC) for beamformed communications are described. A first UE may receive, using a first spatial filter, a first sidelink control message including a first sidelink resource reservation associated with a second UE. Additionally, or alternatively, the first UE may receive, using a second spatial filter, a second sidelink control message including a second sidelink resource reservation associated with a third UE. The first UE may transmit, to the second UE or the third UE, an IUC message that indicates a conflict between the first sidelink resource reservation and the second sidelink resource reservation. The IUC message that indicates a conflict may be based on a relationship between the first spatial filter used to receive the first sidelink resource reservation and the second spatial filter used to receive the second sidelink resource reservation.

    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for determining sidelink channel metrics using reference signal measurements of reference signals transmitted by other UEs. A first UE may receive a control message from a base station, and the control message may indicate a measurement threshold. The first UE may generate a reference signal measurement of a reference signal transmitted by a second UE via a sidelink channel between the first UE and the second UE. The UE may transmit a measurement report to the base station based at least in part on the measurement satisfying the threshold. The report may be a quantized value of the measurement or a bit indicating that the measurement satisfies the threshold. Based on receipt of the measurement report, the base station may determine to transmit data to the second UE via a transmission to the first UE.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a signal. The UE may determine, based at least in part on a machine learning component, a predicted communication metric and a confidence indication, the machine learning component comprising a machine learning model, and wherein determining the predicted communication metric and the confidence indication comprises: receiving, by the machine learning model, an input that comprises an input metric and an error measurement corresponding to the input metric; and providing, by the machine learning model, and based at least in part on a machine learning function and the input, the predicted communication metric and the confidence indication. The UE may perform a wireless communication task based at least in part on the predicted communication metric and the confidence indication. Numerous other aspects are described.
