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.

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

Abstract: Certain aspects of the present disclosure provide techniques for interference mitigation. An exemplary method performed by a base station generally includes determining, based on a location of another base station and information regarding the other base station, that the other base station is likely to experience interference while receiving an uplink transmission due to a downlink transmission by the base station and forming a null in a beam of the downlink transmission in a direction matching the location of the other base station.

Abstract: The present disclosure relates to methods and devices for wireless communication at a wireless device or integrated access and backhaul (IAB) node. In one aspect, the wireless device may determine a frequency synchronization accuracy for the wireless device. The wireless device may also transmit an indication of the determined frequency synchronization accuracy for the wireless device. Additionally, the wireless device may determine an absolute frequency based on a combination of measurements from at least one synchronization source and a frequency of the wireless device, where the frequency synchronization accuracy is based on the absolute frequency.

Abstract: In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for determining, by a user equipment (UE), a first time period for an evaluation procedure during communications with a network entity; performing, by the UE, a first set of measurements of a quality of a first set of discovery reference signals during the first time period; and determining, by the UE, whether to initiate a set of actions associated with the evaluation procedure based on the first set of measurements of the quality of the first set of discovery reference signals.

Abstract: Wireless communications systems and methods related to reducing user equipment (UE)-to-UE cross-link interference are provided. A user equipment (UE) may receive from a base station (BS), a time-division-duplexing (TDD) pattern. The UE may establish a guard band on uplink resources from resources specified in the TDD pattern. Alternatively, the UE may reduce power to uplink resources from the resources specified in the TDD pattern. The UE transmits the resources using a carrier and as specified in the TDD pattern.

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: Aspects of the present disclosure provide techniques for beam and cell selection based on power configuration of a wireless node (e.g., an Integrated Access and Backhaul (IAB) node). In some cases, the node monitors synchronization signal block (SSB) transmissions from one or more network entities, and selects a beam or cell based on the monitoring and one or more metrics designed to limit potential interference caused by uplink transmissions from the first node.
