Abstract: In a channel occupancy time (COT), a scheduling entity can transmit a first downlink (DL) transmission burst to a scheduled entity, and receive an uplink (UL) transmission burst from the scheduled entity. The scheduling entity can determine whether the scheduled entity performed a type 1 or type 2 channel access procedure for the UL transmission burst. A scheduled entity can use a first type of channel access procedure to initiate a first COT on a communication channel and request a network access node to perform a second type of channel access procedure in a next DL transmission burst. A network access node can receive a message from a scheduled entity, wherein the message comprises a control indication requesting the network access node to perform a first type of channel access procedure in a next DL transmission burst.

Abstract: Methods, systems, and devices for wireless communications are described. A phase rotation adjustment may be applied in cases where a transmitted signal is heterodyned. For instance, a device (e.g., a base station, a user equipment (UE), a wireless repeater) may determine that a receiving device may receive a transmitted signal at a carrier frequency that is different from a carrier frequency used by a transmitting device (e.g., such as in the case of a wireless repeater relaying the signal from the transmitting device to the receiving device). A phase rotation adjustment may be applied by the device (e.g., the base station, UE, or wireless repeater) to account for the heterodyning. The phase rotation adjustment may be based on the carrier frequency used by the receiving device to receive the signal. In some cases, a receiving device may also apply the phase rotation adjustment following the demodulation of a received signal.

Abstract: A network management function of a relay network may identify relay node support of multi-mobile terminal (MT) operation, and may coordinate configuration of multiple backhaul links supported by the relay node via the multi-MT functionality of the relay node. In some cases, a relay node may transmit MT capabilities to the management function over a first established backhaul link, and the management function may configure a second backhaul link using a second MT function of the relay node. In other cases, the relay node may autonomously establish multi-MT connectivity based on preconfigured parent-selection policies, and the network management function may identify the relay node is dual-connected to the network management function. In either case, the network management function may configure backhaul routes (e.g., backhaul links) and resource configuration across the redundant topology.

Abstract: Disclosed are techniques for wireless communication. In an aspect, an integrated access and backhaul (IAB) node sets a downlink transmission timing of the IAB node relative to a downlink reception timing of the IAB node based on a first set of values for a set of timing parameters, receives, from a parent IAB node of the IAB node, a second set of values for the set of timing parameters, and transmits, to a positioning entity, a report indicating a change from the first set of values to the second set of values, a new downlink transmission timing based on the second set of values, or a change in downlink transmission timing.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling indicating a first uplink configuration including a first set of resources for uplink transmissions over a carrier and a second uplink configuration including a second set of resources for uplink transmissions over the carrier, where the second set of resources are different from the first set of resources. The UE may transmit, to the base station, a first uplink transmission via the carrier according to the first uplink configuration. The UE may then transmit, to the base station an in accordance with an initiation of a channel occupancy time (COT) for the carrier, a second uplink transmission via the carrier according to the second uplink configuration.

Abstract: Aspects relate to an integrated access backhaul (IAB)-Distributed Unit (DU) resource configuration framework for paired (e.g., frequency division duplex (FDD)) spectrum. Two DU resource configurations per cell may be supported for paired spectrum, including one for a first spectrum band (e.g., a downlink frequency band) and another for a second spectrum band (e.g., an uplink frequency band) of the paired spectrum. Each DU resource configuration may include a respective symbol pattern of symbol types (e.g., downlink (DL), uplink (UL), flexible) for a plurality of slots, as well as a corresponding availability attribute for each symbol type (e.g., hard, soft, or not available). A DU of an IAB node in an IAB network may receive the two DU resource configurations for the paired spectrum from a central unit (CU) of an IAB donor node in the IAB network.

Numerous other aspects are provided.

Abstract: The present disclosure provides techniques for addressing switching times of Integrated Access and Backhaul (IAB) child nodes. For example, a parent IAB node may determine a switching time for the child IAB node to switch from transmitting on a backhaul/uplink to a parent node (with transmit power control) to transmitting on an access/downlink to a user equipment (UE) or other child IAB node. The parent IAB node may then configure the IAB child node according to the determined switching time (e.g., by scheduling the IAB child node accordingly or setting one or more timing advance parameters).
