    Abstract: Methods, systems, and devices for wireless communications are described that support different, or adjusted, random access channel (RACH) preamble formats for efficient use of shared RACH time-frequency resources. The described techniques provide for assigning different RACH preamble formats to wireless devices that have a higher link budget, whereupon the devices may transmit the different RACH preamble using the link budget available to them in one or more RACH transmission opportunities in the shared RACH time-frequency resources. Such methods, systems, and devices may allow for more RACH transmission opportunities, as well as less interference between RACH transmissions. For example, wireless devices communicating over a backhaul network may have a higher link budget than wireless devices communicating over an access network. As such, RACH preambles transmitted by the wireless devices communicating over the backhaul network may be shorter than RACH preambles transmitted by the wireless devices communicating over the access network.

    Abstract: Methods, systems, and devices for wireless communication are described. A wireless node may transmit directional signals in a sweeping transmission pattern while receiving communications from a second wireless node. Another wireless node may then, during a listen-before-talk (LBT) procedure, receive one of the directional signals, and terminate a correspondence communication session to avoid potential interference. Additionally or alternatively, a wireless node may listen in directions in a sweeping receive pattern while transmitting to a second wireless node. While listening, the wireless node may detect a transmission from a third wireless node in a particular direction. The wireless node may then accordingly refrain from transmitting in that direction to avoid potential interference.

    Abstract: Methods, systems, and devices for wireless communications are described that provide for timing adjustments that may be used in communications between wireless devices in a wireless communications system and signaling of such timing adjustments using physical layer signaling (e.g., layer 1 (L1) signaling). A first timing adjustment may be provided by a parent node to one or more associated child nodes that corresponds to a propagation delay between the parent node and its control node or a relay node through which the parent node communicates with a core network. In some cases, the physical layer signaling used to transmit the first timing adjustment may be a reference signal transmission, a downlink control information transmission, or any combination thereof.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a transport block that includes one or more code blocks carrying a random access channel (RACH) communication directed to the UE. The transport block may be segmented into the one or more code blocks based at least in part on a segmentation procedure specific to a RACH procedure. The user equipment may decode the one or more code blocks based at least in part on a code block cyclic redundancy check (CRC) associated with the one or more code blocks. Numerous other aspects are provided.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may transmit a first physical random access channel (PRACH) transmission that includes a first random access (RA) preamble to a base station. The apparatus may determine whether to transmit to the base station a second PRACH transmission that is concurrent with the first PRACH transmission in time, wherein the second PRACH includes a second RA preamble. The apparatus may transmit, to the base station, the second PRACH transmission that includes the second RA preamble when the second PRACH transmission is determined to be transmitted. The first RA preamble and the second RA preamble may be different, and the first RA preamble and the second RA preamble may be concurrently transmitted in a same PRACH occasion or in different PRACH occasions that overlap in time.

    Abstract: An access node may monitor for uplink and downlink resource release indications signaled by a parent access node and a child access node prior to scheduling a released resource. In some cases (e.g., when the child node is capable of half-duplex communications), the parent access node may determine to release a resource, and the child access node may determine to release a hard resource (e.g., a child node controlled resource). Receiving uplink and downlink resource release indications may enable the access node to schedule communication with the child node via a soft resource (e.g., a parent node controlled resource). Other aspects of the described techniques are directed to feedback support for a slot format indicator (SFI). The feedback from the access node may accept or reject the SFI based on an impact the SFI has on scheduling via a child link established with a child node of the access node.
