Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure provide a user equipment (UE) with a capability to identify an enhanced sidelink resource pool including resources that are otherwise excluded from configured sidelink resource pools. In some examples, the UE may identify the enhanced sidelink resource pool based on sidelink parameters for transmitting one or more sidelink messages, and the UE may use the enhanced sidelink resource pool for additional sidelink transmissions. The additional sidelink transmissions may include standalone sidelink control information (SCI) transmissions or other types of transmissions associated with sidelink communications. The resources associated with the enhanced sidelink resource pool may have a relatively finer granularity than those included within a base sidelink resource pool that is, for example, configured by a network.

The network entity may transmit, for the network node, a diode bias voltage configuration for a plurality of diodes or a plurality of RIS elements of the network node. The diode bias voltage configuration may be associated with the RIS pattern configuration.

Abstract: Certain aspects of the present disclosure provide techniques for dynamically updating a forwarding configuration of a mobile repeater. An exemplary method for wireless communications at a repeater includes modifying a forwarding behavior based on a change in channel condition of a communications link between the repeater and a network entity and forwarding one or more communications between the network entity and a user equipment (UE) in accordance with the modified forwarding behavior.

Abstract: A repeater BWP switching schedule is provided for a repeater that is responsive to a user equipment BWP switching schedule. Should the repeater support a plurality of active user equipments, the user equipment BWP switching schedule is a superset of the BWP switching schedule for each individual user equipment. The repeater BWP switching schedule may thus be more granular than the UE BWP switching schedule.

Abstract: Aspects described herein relate to resource allocation in an integrated access and backhaul (IAB) system. A central unit (CU) transmits over a backhaul link a message to a distributed unit (DU) including a resource configuration for a DU cell and a child cell corresponding to a child node served by the DU cell. The DU determines that the message misidentifies the child cell using an ID of a different cell. In response to that determination, the DU communicates with the child node based on the resource configuration specific to the misidentified child cell. Using this coordinated technique enables the CU to provide the DU with a child-node specific resource configuration to enable the DU to use this configuration for communicating with the child node. This maximizes efficiency in multi-node communications between one or more child nodes and cells while adding minimal, if any, signaling overhead.

In some cases, the UE may transmit an indication of the sidelink DRX parameters to another UE (e.g., via a sidelink communication link). A UE may discontinuously monitor for transmissions over the sidelink communication link in accordance with the sidelink DRX parameters.

The assistive node may transmit a message to a network entity indicating that the assistive node is capable of operating in an amplifying mode or a reflecting mode. The network entity may transmit scheduling information to the assistive node for a packet transmission to be reflected or amplified by the assistive node to a wireless device, for example, because a direct path between the network entity and the wireless device is blocked. The network entity may transmit control signaling to the assistive node configuring the assistive node to either reflect or amplify the packet transmission to the wireless device. The assistive node may reflect or amplify the packet transmission to the wireless device based on the control signaling.
