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).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit a set of reference signals to a first wireless node; receive information identifying a transmit power capability of the first wireless node based at least in part on transmitting the set of reference signals; and configure one or more transmission parameters for a first link with the first wireless node or a second link with a second wireless node based at least in part on the transmit power capability of the first wireless node. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques for addressing scenarios where the minimum transmit power supported by a wireless node (e.g., an Integrated Access and Backhaul (IAB) node) is above a minimum value specified by a standard. In some cases, the node may signal information regarding its power configuration so a network entity of the may take it into account (e.g., when allocating or scheduling resources). The power configuration may include an indication of the minimum transmit power supported by the node and/or an indication of a guard band that may help the IAB control adjacent channel leakage.

Abstract: Methods, systems, and devices for wireless communications are described to enable a mobile access node to enter a new power state based on detection of a second access node. The second access node may be detected by the mobile access node or a central unit (CU). The mobile access node or the CU may determine for the mobile access node to enter a new power state and may notify the other of the determination. The mobile access node may enter a lower power state if the second access node is within a defined proximity or if one or more thresholds are exceeded. The mobile access node may enter a higher power state if no other access nodes are within the defined proximity or if the one or more thresholds are not exceeded. Configuration parameters for a power state change procedure may be configured by control signaling from a CU.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine an emissions mask (e.g., an in-band emission (IBE) mask) for a user equipment (UE) which may be determined based on the total number of UEs scheduled by the base station for uplink transmissions during a same transmission time interval (TTI). The base station may transmit downlink control information (DCI) to the UE indicating the emissions mask. The base station may additionally transmit a grant to the UE allocating resources for the UE based on the UE's position relative to other UEs served by the base station. The UE may receive the DCI and may map the emissions mask to a maximum power reduction (MPR). Based on the MPR, the UE may determine a transmit power and may transmit an uplink transmission to the base station according to the transmission power and the DCI.

Abstract: Methods, systems, and devices for beamforming in environments with angular constraints are described. A wireless device such as a user equipment (UE) or base station may configure beam parameters based on a sensitivity level of a neighboring wireless device (e.g., a satellite). The configuration of beam parameters may be based on an interference power profile (e.g., threshold(s) indicated by an interference power profile). The interference power profile may specify a mask, which may indicate allowed or unintended directions for transmission or a transmission power mask. A beamformed transmission may be in accordance with the configured beam parameters, which may result in a reduced transmission power in one or more directions, compliance with total power limits, peak power limits, or energy radiated over a period of time, or any combination thereof.
