Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for wireless communication by a mobile wireless node of a wireless backhaul communications network. In one aspect, the mobile wireless node determines a first set of communication resources for use by the mobile wireless node. The wireless node communicates with one or more wireless device, via one or multiple child links, using the first set of communication resources while the wireless backhaul communications network has a first topology and while the wireless backhaul communications network has a second topology.

Abstract: Methods, systems, and devices for wireless communications are described to coordinate information across a wireless network. One or more access nodes of a wireless network may configure a time resource container for receiving, amplifying, and forwarding a signal, such as a notification signal, in an operating mode. A notification signal may include an indication of coordination information and may be transmitted or received in the time resource container, such as in a first subset of a set of time resources of the time resource container. An access node may first receive a signal from a second access node, amplify and forward the signal in the time resource container to a third access node, and then decode the received signal and determine whether the signal includes coordination information for the access node. If the signal includes coordination information for the access node, the access node may perform one or more actions.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit, to a user equipment (UE) operating in a discontinuous reception mode, a wakeup signal indicating whether data is available to be transmitted to the UE, the wakeup signal transmitted using a first set of transmit beams, which may be selected from a periodic beam management procedure, in accordance with a beam sweeping configuration. The base station may receive, from the UE and based at least in part on the wakeup signal, a response signal. The base station may perform, based at least in part on the response signal, further beam update procedures to identify a second set of transmit beams for future transmissions of the wakeup signal and/or for transmission of physical downlink control channel (PDCCH) to the UE.

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 that provide for multiple timing advance offsets that may be used in communications between wireless devices on a wireless communications system. A first timing advance offset may be a fixed offset that has a predetermined value or is selected from a set of available predetermined values, and a second timing advance offset may be adjustable by a wireless device. The second timing advance offset may be used in cases where relatively large distances between wireless devices are present in a system, where certain fixed timing advances are used in addition to or irrespective of a receiving devices propagation delay, where one or more parent nodes have an associated timing reference, or combinations thereof.

Abstract: Aspects described herein relate to communicating timing advance (TA) values in an integrated access and backhaul (IAB) network. A first node in a wireless network can receive a media access control (MAC) control element (CE) indicating a downlink transmission timing advance for transmitting downlink communications. The first node can transmit downlink communications based on the MAC CE.

Abstract: Methods, systems, and devices for wireless communications are described. A scheduled node may transmit, by a first node in the network and to a second node in the network, an indication of a first temporal pattern of communication states for communication by the first node on a first set of resources, the first node being configured for half-duplex communications. The scheduled node may receive, from the second node, a grant of resources for performing communications on a second set of resources that are multiplexed with the first set of resources in a frequency domain, a spatial domain, or a combination thereof.

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.

Abstract: Methods, systems, and devices for wireless communications are described that provide for partitioning of time-frequency resources for types of traffic separately. A centralized scheduler in a centralized system or a set of access nodes (ANs) in a distributed system may allocate a portion of a set of resources for a first traffic type (e.g., control or data traffic). In some cases, multiple ANs may exchange reports or measurements to determine the resources to allocate to a given traffic type. The allocated resources may be repurposed for use by a different traffic type (e.g., data traffic resources may be repurposed an used for control traffic resources) in order to account for varying traffic conditions (e.g., unscheduled control traffic).

Abstract: Methods, systems, and devices for wireless communication are described for discontinuous reception (DRX) wake up procedures over millimeter wave (mmW) frequency resources. A base station may use multiple antenna ports to transmit one or more beamformed downlink transmissions to a user equipment (UE). The downlink transmissions may include beam-swept reference signals, and the UE may initiate a wake up procedure prior to a configured DRX-On cycle to receive the reference signals. Based on the reception of the reference signals, the UE may train a set of receive beams and determine a preferred downlink transmit beam. The base station may subsequently transmit at least a portion of a cell radio network temporary identifier (C-RNTI) in a beam-swept manner, and the UE may evaluate the C-RNTI transmission on the preferred transmit beam. The UE may also transmit an uplink response indicating the preferred transmit beam to receive downlink data.
