    Abstract: Techniques are provided for supporting sidelink communication between multiple user equipment (UEs), and which may be implemented in various apparatuses, methods, and/or articles of manufacture. In certain aspects a first UE may establish a sidelink schedule with a second UE, wherein the sidelink schedule corresponds to at least a subset of communication resources indicated available to both the first and second UEs by one or more corresponding link availability schedules or the like. The two UEs may then establish a sidelink with the second UE in accordance with the sidelink schedule. Multiple sidelink schedules may be agreed upon in certain instances such that the UEs may dynamically switch from one schedule to another as desired.

    Abstract: Methods, systems, and devices for wireless communication are described. One method for wireless communication at a first device includes receiving a multicast packet from a second device, decoding control header information in the received multicast packet, determining that a decoding procedure associated with a payload of the received multicast packet is unsuccessful and transmitting a negative acknowledgement (NACK) based at least in part on the determining. The method also includes retrieving a list of transmitter identifiers. In some cases, transmitting the NACK is based at least in part on the list of transmitter identifiers. The method further includes determining a transmitter identifier associated with the multicast packet and determining that the transmitter identifier is present in the list of transmitter identifiers.

    Abstract: Methods, systems, and devices for wireless communication are described that provide for priority-based carrier selection in a system using multiple component carriers (CCs). A mapping may be provided that maps different applications that may be present at a user equipment (UE) to one or more CCs. Each application may have an associated application priority, and each carrier associated with an application may also have an associated CC priority. A UE may select a subset of CCs for a transmission based on the mapping between an application providing a packet for the transmission and the priority associated with each CC. A UE, when receiving transmissions, may identify one or more applications running at the UE and use the mapping to determine a subset of CCs to monitor for transmissions.

    Abstract: A user equipment (UE) may experience poor communication with a network access device, and the network access device may configure the UE to connect to, and route communications through, one or more relay nodes (e.g., which may be another UE, a network operator-deployed relay, etc.). Techniques are described whereby these relay nodes may autonomously form a wireless backhaul network. Sequential implementations are considered such that the size of the wireless backhaul network may scale efficiently. In some examples, the wireless backhaul network may form by reusing existing connectivity establishment procedures. Importantly, the proposed techniques enable a relay to possess (e.g., be configured with) functionality that may traditionally be associated with a UE, base station, and gateway. Such multi-faceted functionality may enable the described sequential formation of wireless backhaul networks with tree topology.

    Abstract: Methods, systems, and devices for wireless communications are described. A relay device may detect an upstream radio link failure (RLF) associated with an upstream link of a wireless backhaul, where the wireless backhaul includes a first wireless link between the relay device and a first upstream backhaul device. The relay device may provide a first indication of the upstream radio link failure over a second wireless link between the relay device and a first downstream device. The relay device may establish a third wireless link with a second upstream backhaul device based on the detected upstream radio link failure. The relay device may provide multiple-access services to one or more downstream devices, where providing the multiple-access services is based on backhaul communications between the relay device and the second upstream backhaul device over the third wireless link.

    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless systems, a base station centralized unit (CU) may communicate with a user equipment (UE) through a multi-hop backhaul architecture. This multi-hop backhaul connection may include a donor base station and any number of relay base stations connected via backhaul links. In some cases, the relay base stations or the UE may experience data congestion in a logical channel-specific buffer. The relay base stations or UE may implement backpressure signaling (e.g., in the medium access control (MAC) layer) to mitigate the congestion. A wireless device operating as a mobile termination (MT) endpoint may transmit a backpressure report message to a wireless device operating as a base station distributed unit (DU) endpoint for the logical channel. The base station DU may adjust a scheduling rate for data unit transmissions over the indicated logical channel based on the backpressure report.
