Abstract: Wireless communications systems and methods related to managing interference among feedback transmissions are provided. A first wireless communication device receives, from a second wireless communication device, a first forward data transmission request signal over a first link in a first link direction, wherein the first forward data transmission request signal is associated with a first feedback transmission over the first link in a second link direction opposite the first link direction. The first wireless communication device yields, in response to the first forward data transmission request signal, access to a channel resource for the first feedback transmission based on at least an interference tolerance level of the second wireless communication device and an interference level on the first feedback transmission from the first wireless communication device.

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: Wireless communication systems and methods related to the discovery and selection of relay devices by internet of everything (IoE) devices are disclosed. For example, IoE devices with low pathloss to a base station can broadcast information during discovery frames that allow other IoE devices to discover them and select them as a relay, if appropriate. The discovery broadcast message from an IoE device can include information to allow a listening IoE device to select a suitable IoE device for relaying its data that satisfies latency parameters while minimizing the energy impact of relaying. Signaling structures are also provided to allow different IoE devices to select slots for broadcasting within the discovery frame in a distributed manner without disrupting existing periodic broadcasts. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. A first UE and a second UE may coordinate to establish a sidelink connection. The first UE may identify data to transmit to the second UE, and the first UE may transmit a request to send (RTS) message to the second UE with a first transmit power. The first UE may then determine to refrain from using the first transmit power for the data transmission, and the first UE may transmit the data to the second UE with a second transmit power that is different from the first transmit power. The UE may determine the second transmit power for the data transmission based on instantaneous channel quality information (CQI) received in a clear to send (CTS) message, a modulation and coding scheme (MCS) selected for the data transmission, a threshold power, etc.

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: A user equipment (UE) may, in a first discovery frame, determine whether a discovery resource is available for communication. If the discovery resource is available for communication, the UE may, in a second discovery frame following the first discovery frame, transmit a discovery signal using the discovery resource and puncture the discovery signal during a listening window. The UE may detect the energy of a received signal at the discovery resource during the listening window. The UE may abandon the discovery resource if the detected energy is above a threshold. In some example, the listening window may have a fixed duration and a beginning that is randomly selected from a predetermined set of values. In some example, the listening window may have a variable duration and an end that matches an end of the second discovery frame.

Abstract: Wireless devices in a wireless network may use multiple communication modes to perform device-to-device (D2D) communication in a mesh wide area network (WAN). For instance, one communication mode may be contention-based, while the other communication mode may be scheduled (e.g., by a relay). To facilitate co-existence between these communication modes, a wireless device may identify a set of resources set aside for D2D communications and may select and reserve a transmission time interval (e.g., a slot) of the D2D resources. Other wireless devices may determine the transmission time interval is reserved and refrain from transmitting during that transmission time interval. In another example, a base station may assign a D2D communication mode to certain sets of D2D resources.

Abstract: In an aspect of the disclosure, a method, a computer program product, and an apparatus are provided. The apparatus may be a first node. The first node determines to transmit a first packet to a second node in a first data slot of a first frame. The first data slot being associated with a first reservation resource and a second reservation resource. The first node determines whether the first node has a privilege for the first data slot of the first frame, when the first packet is of priority based traffic. The first node transmits a reservation message to the second node in the first reservation resource when the first node is determined to have the privilege for the first data slot.

Abstract: Systems and methods are disclosed for efficient signaling between devices. A relay device initiates association with discovery broadcast signals to leaf devices. Each leaf responds with association request signals. After association, the relay periodically sends stay alive signals to the leaf, and the leaf periodically sends link confirmation signals to the relay. 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. In another embodiment, the leaf foregoes association with a relay, instead forming a device to device (D2D) connection with a relay. A D2D connection is used when the leaf does not expect a link to a relay to be stable enough to justify the association overhead, or when downlink traffic is arriving more frequently than an associated relay is awake. Other aspects, embodiments, and features are also claimed and described.
