Abstract: Methods, systems, and devices for wireless communications are described. Generally, the techniques described herein may support generating an average effective isotropic radiated power (EIRP) mask in accordance with a set of weighted values to support interference management. For example, a wireless device may obtain one or more information bits for transmission by the wireless device via a transmit beam of multiple transmit beams of the wireless device and may generate, based on one or more directional parameters associated with a beamforming direction of the transmit beam, a set of weighted values for an average EIRP mask for the transmission of the one or more information bits. Additionally, the wireless device may transmit, via the transmit beam in the beamforming direction based on the one or more directional parameters and the set of weighted values, a signal comprising the one or more information bits to meet the average EIRP mask.

Abstract: Certain aspects of the present disclosure provide techniques for synchronization signal block (SSB) based spectrum coexistence. An example method, performed at a network entity of a first radio access technology (RAT) network, includes outputting, for transmission, signaling configuring a user equipment (UE) to perform a search and measurement procedure associated with signals on frequency bands that are shared between the first RAT network and a second RAT network, obtaining, from the UE, a report with information indicating results of the search and measurement procedure, and performing one or more actions to mitigate interference based on the information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain emission control information that indicates a first emission control configuration associated with a first operating configuration and a second emission control configuration associated with a second operating configuration. The UE may transmit, using the first emission control configuration or the second emission control configuration based at least in part on a UE operating configuration associated with the UE, a communication. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatus for clear channel assessment (CCA) enabled narrowband (NB) communications. In some implementations, a device is configured to associate with an NB channel (such as a Bluetooth channel), perform a CCA to assess whether the NB channel is clear, and transmit on the NB channel when clear. If the NB channel is not clear, the device may prevent transmitting on the NB channel. The device may prevent avoiding the NB channel after the first time that the NB channel is not clear. If the NB channel remains not clear (such as over a number of CCAs for the NB channel), the device may avoid the NB channel by removing the NB channel for FH for an amount of time. In some implementations, the device may be configured to perform frame based equipment (FBE) CCAs for one or more NB channels.

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: Techniques for a node to adjust or update its CW are provided. The node transmits at least one transmission during a channel occupancy time (COT). The node can determine or adjust a contention window (CW) size following the end of COT based on whether feedback for a transmission is received or could be scheduled during the COT.

Abstract: In order to provide a generic access rule, the present disclosure proposes a new potential set of adaptivity rules for LBE based on LBT. The generic access rule of the present disclosure provides LTE-U and Wi-Fi coexistence and DL/UL coexistence in both LTE-U and Wi-Fi. The apparatus receives, from the first master device, a resource allocation for communicating with the second master device. The apparatus also determines a type of CCA procedure to perform before communicating with the second master device on an unlicensed channel. The apparatus further performs a CCA procedure to obtain a transmission opportunity based on the determining, the CCA procedure being one of an ICCA procedure or an ECCA procedure. In addition, the apparatus transmit data to the second master device in accordance with the resource allocation on the unlicensed channel when the transmission opportunity is obtained.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network entity may transmit during a first time interval in accordance with a first effective isotropic radiated power (EIRP) limit, wherein the first EIRP limit is associated with a first beamforming vector corresponding to a single peak in a beamspace, and transmitting during a second time interval in accordance with a second EIRP limit lower than the first EIRP limit, wherein the second EIRP limit is for a multiple beam communication condition. Numerous other aspects are described.

Abstract: Wireless communications systems and methods related to accessing a channel based on an interference condition in a wireless communication network are provided. For example, a method of wireless communication performed by a wireless communications device may include receiving, from a second wireless communication device, one or more signals associated with a beam parameter, determining, at each of a plurality of locations, a signal measurement for at least one received signal of the one or more received signals, and determining, based at least in part on a cumulative distribution of the signal measurements at the plurality of locations and a reference probability distribution, whether the second wireless communication device satisfies an interference condition. Other features are also claimed and described.
