Abstract: A user equipment (UE) may determine that a synchronous transmission by the UE includes traffic having a priority higher than a priority of nominal traffic. In response to the determination, the UE may, alter a use of at least some of an initial portion of a discovery frame from energy detection to signal transmission. The signal transmission may be a pilot signal transmission or a non-information-carrying signal transmission. The traffic having the priority higher than the nominal traffic may include mission-critical traffic. A reliability requirement of mission-critical traffic may be higher than a reliability requirement of nominal traffic. A latency requirement of mission-critical traffic may be lower than a latency requirement of nominal traffic. The signal transmission may be at a power level that is sufficient to result in energy detection at another UE. Various additional and alternative aspects are described herein.

Abstract: Methods, systems, and devices for wireless communication are described. A relay wireless node may receive, during a first transmit time interval (TTI), a data message to be forwarded to a wireless node. The relay wireless node may forward the data message to the wireless node during the first TTI. The relay wireless node may receive, during a second TTI, a feedback message from the wireless node. The relay wireless node may retransmit the feedback message during the second TTI.

Abstract: Methods, systems, and devices for wireless communication are described. In an FDD system, a UE may identify an indicator associated with ultra-reliable low latency communications (URLLC) while communicating in a sidelink channel. The UE may also identify dedicated uplink resources in the sidelink channel, and reserve the dedicated uplink resources. The dedicated uplink resources may be reserved for an acknowledgement/negative acknowledgement (ACK/NACK) feedback or for a scheduling request (SR). URLLC data may be communicated, and the reserved uplink resources may be utilized to transmit an ACK/NACK feedback or a SR. In a TDD system, a base station may transmit information identifying dedicated resources for URLLC data. In some cases, a base station may transmit an indicator channel, which a sidelink UE may monitor to determine the presence of URLLC data, and respond accordingly.

Abstract: A first device may configure a second device, such as a sidelink receiver, so that an interference protection zone surrounding the second device may be dynamically adjusted in size based, for example, on various objectives and/or use cases recognized by the first device. The interference protection zone may be, for example, an area surrounding the second device, within which neighboring devices may be silenced. Changes to the interference protection zone may be achieved by providing a dynamic clear-to-send (CTS) transmit power scaling parameter, that is different from a pre-assigned constant parameter for CTS power control stored at the second device, to the second device from the first device. The second device may calculate CTS channel power using at least the dynamic CTS transmit power scaling parameter and the received RTS channel power. The second device may send a CTS message in a CTS channel at the calculated CTS channel power.

Abstract: Aspects of the present disclosure provide solutions that can mitigate interference between sidelinks. A user equipment (UE) can directly communicate with another device using a sidelink or sidelink channel without necessarily relying on a scheduling entity (e.g., a base station). The UE may transmit a direction selection signal (DSS) to another sidelink entity to indicate a requested duration of time to keep a first sidelink available for a plurality of transmission time intervals. The UE may perform various processes to mitigate interference between the first sidelink and a second sidelink established between other sidelink entities. To mitigate interference between sidelinks, for example, the UE may puncture its sidelink data during a time period that overlaps with a destination receive signal (DRS) of another sidelink. In another example, the UE may receive a retransmission of a DRS that may not be received due to sidelink interference.

Abstract: Aspects of the disclosure relate to a sidelink signal communication scheme that provides for rapid adaptation of the sidelink transmission based on feedback received during each transmission time interval (TTI). In this way, any lack of precision in interference measurements, or rapid changes in the amount of interference, which otherwise might cause a modulation and coding scheme (MCS) that was selected for the sidelink transmission to be unsuitable, may be adapted to improve the reliability of the transmission. Other aspects, embodiments, and features are also claimed and described.

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: Systems and methods are disclosed for efficient signaling between devices. A leaf device initiates association with chirp signals to relay devices. Relay devices respond with keep alive signals. The leaf device selects a relay (from those that responded) and associates with it. Alternatively, selection of the relay may be offloaded to a base station. In another embodiment, an available relay device transmits a discovery broadcast to leaf devices. A leaf device responds with a chirp signal to the relay and association occurs. After association, the leaf device periodically sends a chirp signal and the relay responds with a keep alive signal. If either device fails to send its signal, link breakage is assumed. The leaf device reverts to uplink communication with a base station while searching for another relay. Downlink paging may be synchronized with the chirp/keep alive signaling. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. The method may involve a first user equipment (UE) receiving an indication of a set of sidelink resources and an indication of a set of uplink resources for transmitting sidelink feedback information. The first UE may receive a sidelink shared channel transmission from a second UE and upon receiving the sidelink shared transmission, generate feedback information regarding the sidelink shared channel transmission and transmit the feedback information directly to the base station using the set of uplink resources.
