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 node in a multi-hop network may receive a configuration that indicates a first set of physical downlink control channel (PDCCH) resources dedicated to PDCCH monitoring by the node, a second set of PDCCH resources dedicated to PDCCH transmission by the node, and a third set of PDCCH resources permitted to be configured for either PDCCH monitoring by the node or PDCCH transmission by the node. The node in a multi-hop network may configure a resource of the third set of PDCCH resources for one of PDCCH monitoring or neither PDCCH monitoring nor PDCCH transmission based at least in part on an initial state associated with the resource. Numerous other aspects are provided.

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.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a first IAB node determining an adjustment to at least one parameter corresponding to a cell coverage of the first IAB node based at least in part on a geographic proximity of a cell relative to the first IAB node. For example, the first IAB node may determine to adjust the parameters based reference signal measurements, signal quality measurements (e.g., received from child nodes or user equipments (UEs)), etc. In another example, the first IAB node may receive an instruction from a central unit (CU) of the IAB network to adjust the at least one parameter. The first access node may transmit an indication of the adjustment to the at least one parameter. For example, the first access node may signal the adjustments to the CU, child IAB nodes, UEs and/or, other IAB nodes.

Abstract: Methods, systems, and devices for wireless communications are described that provide for cooperative full-duplex techniques for sidelink communications. A first device that supports full-duplex communications may transmit a first message to a second device while concurrently receiving a second message from a third device. The first device may determine a set of parameters that indicate a presence of one or more objects that cause interference at the first device based on communicating with the second and third devices. The set of parameters may include location information, directional beam information, main beam information, and null interference beam information, or velocity information, or any combination thereof. The first device may broadcast an indication of the set of parameters to other devices. In some examples, a device that receives the set of parameters may determine communications parameters for communication with other devices that accounts for the indicated objects.

Abstract: The apparatus may be a base station. The apparatus sets a first numerology for at least one synchronization signal of one or more synchronization signals to be different from a second numerology for at least one data signal of one or more data signals. The apparatus transmits the one or more synchronization signals to a user equipment (UE) based on the first numerology. The apparatus transmits the one or more data signals to the UE based on the second numerology.

Abstract: An apparatus are provided for wireless communication at a base station with improved PBCH construction and decoding. The base station apparatus constructs a PBCH payload, wherein a bit location is selected for encoding a plurality of bits of the PBCH based on an estimated reliability for the corresponding bits location wherein the plurality of bits comprises frozen bits, unknown bits that are unknown to a user equipment, and potentially known bits that are potentially known by the user equipment. The apparatus transmits the PBCH payload in at least one of a plurality of SS blocks. A UE receiving the PBCH decodes the PBCH based on a successive decoding order. The successive decoding order may be based on an estimated reliability for the corresponding bits, e.g., in which potentially known bits are decoded prior to unknown bits.

Abstract: The present disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for an autonomous fallback for a full-duplex beam pair. In a first aspect, a first wireless device may determine an occurrence of a performance trigger for a current beam pair for full-duplex communication at the first wireless device and use a fallback full-duplex beam pair in response to determining the occurrence of the performance trigger. In a second aspect, the first wireless device may receive an indication from a second wireless device of an occurrence of the performance trigger for the current beam pair for full-duplex communication and using the fallback full-duplex beam pair for communication with the second wireless device in response to receiving the indication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a client device may receive a discovery signal from a host device; determine whether to use a receive timing from the host device, an internal timing of the client device, or a combination of the receive timing and the internal timing to configure a reference timing; configure the reference timing, for transmission of a response to the discovery signal, using the receive timing from the host device, the internal timing of the client device, or the combination of the receive timing and the internal timing based at least in part on the determination of whether to use the receive timing, the internal timing, or the combination of the receive timing and the internal timing; and transmit the response to the host device using the configured reference timing. Numerous other aspects are provided.

Abstract: An intermediary base station supporting mobile terminal (MT) functionality and/or a user equipment (UE) may receive a time alignment (TA) command and associated timer value from one or more distributed units (DUs) and/or a central unit (CU) of a parent base station. The TA command and timer value may be based on an experienced or potential timer expiration associated with a TA of a communication link. The TA command may specify an updated TA value and a timer reset for scheduling communications on the communication link. In some examples, the TA command may be in response to a TA command request provided by the MT or UE on allocated resources or configurations indicated by the parent base station. In other cases, the TA command may be in response to a random access procedure on allocated resources or configurations indicated by the parent base station.
