User equipment may configure a transmitter or receiver to conform to regulations or standards of a geographical region to communicate with non-terrestrial networks (e.g., satellite networks). In one embodiment, the user equipment may receive an indication of a regulation or standard to which to conform to from a terrestrial communication node, and apply an emission mask to the transmitter based on the regulation or standard. The user equipment may additionally or alternatively configure the receiver to be compliant with a noise level tolerance of a received signal specified by the regulation or standard. In some embodiments, the user equipment may implement a frequency offset between the received signal and an interfering signal associated with the noise level tolerance that is scaled based at least on a channel bandwidth associated with the desired signal. Moreover, the user equipment may scale the noise level tolerance based on the frequency offset.

A wireless device may determine a calculated total transmit power for a plurality of signals. The plurality of signals may include a first uplink signal and a second uplink signal. The first uplink signal may be configured for transmission, during a time interval, via one or more first cells of a first cell type. The second uplink signal may be configured for transmission, during the time interval, via one or more second cells of a second cell type. The wireless device may drop a transmission of the first uplink signal or scale a transmission power of the first uplink signal, based on a transmit power priority of the first uplink signal and in response to the calculated total transmit power exceeding a first value. The transmit power priority may be based on a cell type of the one or more first cells.

A user equipment (UE) may identify a maximum transmission power for an uplink transmission on a first cell of a first cell group (CG) based on a direction of communications (e.g., uplink, downlink, or flexible) with a separate cell of a second CG during a same duration of the uplink transmission and within a same first frequency range, where the direction of communications is either an actual direction or an assumed direction. The UE may receive an uplink grant scheduling the uplink transmission during a symbol and within the first frequency range, determine the maximum transmission power for the UE based on the direction of communications for the separate cell during the symbol and within the first frequency range, and subsequently transmit the uplink transmission in accordance with the maximum transmission power.

Generally, the described techniques provide for managing remote interference using a previously detected relationship between an aggressor base station and a victim base station. The described techniques provide for allocating reference signal sequences for various victim base stations to send to an aggressor base station. The victim base station may trigger the aggressor base station to perform reference signal monitoring based on the previously detected victim-aggressor relationship, and may transmit a reference signal carrying a unique identifier based on the triggering. The first base station may send a request that the second base station to transmit a reference signal for enabling the first base station to measure interference of a wireless channel, and performing interference mitigation techniques at the first base station, the second base station, or both, to mitigate the remote interference.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) configured for a periodic channel stat information (CSI) reference signal (CSI-RS) configuration may request an update for one or more parameters of the periodic CSI-RS configuration. For example, the UE may transmit request to a base station for a longer periodicity based on detecting a low Doppler scenario or little variance to wireless channel conditions, or the UE may request a shorter periodicity based on detecting a high Doppler scenario or high variance to wireless channel conditions. The base station may update a configuration for CSI or for CSI-RS based on the request. For example, the base station may update a periodicity for the periodic CSI-RS configuration based on the requested periodicity.

By using this approach, interference suppression involving a primary user and a secondary user can be optimized to ensure superior system performance of a primary system.
