    Abstract: 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.

    Abstract: Embodiments disclosed herein relate to techniques for measuring and/or detecting a signal-to-interference ratio (SIR) of a received signal at a user equipment (UE). The received signal may include a desired signal, co-channel interference, adjacent channel interference, and an in-band blocker. The UE may filter (e.g., remove) the various interferences and in-band blocker. The UE may determine or measure a power (or Received Signal Strength Indicator (RSSI)) of the desired signal and a power (or RSSI) of the co-channel interference separately because the desired signal and the co-channel interference overlap in frequency. To do so, the UE may determine a total power of the received signal including the desired signal and co-channel interference. The UE may receive the desired signal again while an uplink transmission is deactivated (and thus without the interference). The UE may then calculate the SIR based on the total power and the power of the desired signal.

    Abstract: A base station sends system information to user equipment based on the user equipment detecting network coverage provided by the base station. The system information may include one or more network signaling flags indicative of a legacy regulation and an updated regulation (or a legacy version of a regulation and an updated version of the regulation) for operating on a frequency band. The user equipment transmits an indication to the base station as to whether it supports the legacy regulation and/or the updated regulation. The base station configures uplink and/or downlink resources on the frequency band for the user equipment based on the regulation indicated. The user equipment and the base station then communicate using the configured resources on the frequency band.

    Abstract: A base station may send an indication of frequency subranges supported by the base station to user equipment, which may respond with an indication of the frequency subranges that are also supported by the user equipment. Additionally, a Spectrum Access System (SAS) controller, using environmental sensing capability sensors, may determine whether non-federal networks are disposed in a coverage area of a base station and neighboring coverage areas. If so, then the SAS may indicate to the base station to send an indication to user equipment in the coverage area to operate using a default power mode. Otherwise, the SAS may indicate to the base station to send an indication to the user equipment to operate using a lower power mode. Moreover, a base station may indicate a regulatory requirement to user equipment using network signaling value of multiple network signaling values corresponding to multiple regulatory requirements of multiple geographical regions.

    Abstract: Embodiments of the present disclosure are directed to allocating a satellite band (e.g., a satellite channel) with a New Radio (NR) channel and at least one Long-Term Evolution (LTE) channel to enable a user equipment to communicate using a satellite network. The satellite band may be configured to include the NR channel positioned (e.g., placed) such that the NR channel is shifted away from an edge of the satellite band (e.g., not disposed or located at the edge of the satellite band) and/or in the middle (e.g., center) of the satellite band with respect to frequency. Additionally, the satellite band may be configured to include the at least one LTE channel positioned at one or both of outer edges of the satellite band (rather than the middle). Further, the NR channel may be placed within a carrier center frequency range to reduce allowed additional maximum power reduction (A-MPR) values.

    Abstract: The present disclosure relates to systems and methods for indicating to a spectrum access system communication preferences of a base station and/or of a network operator. Different methods may be used to indicate the communication preferences, including a dedicated type parameter transmitted with spectrum allocation requests from the base station, a rule-based system where the spectrum access system accesses communication preferences of the base station and/or network operator through an identifier corresponding to a rule definition, or the like. The spectrum access system may assign a channel to the network operator based on its communication preferences, such as to determine a channel assignment to correspond to a channel aligned with a raster of communications to be used by the network operator. If the channel is not aligned, then the base station may shift a center frequency of the channel so that the channel aligns with the raster of communications.
