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: This disclosure is generally directed to systems and methods for high power operation in user equipment. The user equipment may indicate to a network high power capability of the user equipment. Based on an uplink signal strength of the user equipment, the network may send a command to the user equipment to transmit using the high power user equipment (HPUE) operation in half-duplex frequency division duplex (HD-FDD) mode. The network may also send a signal for the user equipment to return to a default power mode based on the uplink signal strength. The user equipment may then reconfigure to the default power in full-duplex frequency division duplex (FD-FDD) mode. The user equipment may also send an indication of an uplink duty cycle which indicates the ratio of uplink allocations corresponding to uplink transmissions relative to total uplink and downlink allocations.

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: An electronic device discussed herein may communicatively couple to a base station. The base station may receive a first paging cycle assignment corresponding to a first subscriber identification module (SIM) card and determine a second paging cycle assignment for use with a second SIM card. The second paging cycle assignment may be generated based on the first paging cycle assignment. The base station may communicate with the electronic device using the second paging cycle assignment. The second paging cycle assignment may guide the base station to transmit data to the electronic device without interrupting a transmission made according to the first paging cycle assignment.

Abstract: The present disclosure relates to systems and methods for operating transceiver circuitry to transmit or receive signals on various frequency ranges. To do so, an electronic device may determine a receive delay between one or more messages received on different component carriers and may transmit the receive delay to a base station to update how communications are transmitted on one of the component carriers. The update made to at least one of the component carriers may compensate for the receive delay between the different component carriers. Compensating for the receive delay may improve operations that delay downlink communications to reduce a likelihood or stop simultaneous downlink and uplink communications by further adjusting for delays seen at an electronic device when communicating with base stations disposed at a different distances from the electronic device.

Abstract: A communication network broadcasts an indication of a frequency band and an indication of a partial frequency band. User equipment receives the broadcasted indications, if it may operate on the full frequency band, transmits an indication. The network then configures the user equipment to operate on the full frequency band, and the user equipment communicates with the network using the full frequency band. Otherwise, the user equipment transmits an indication that it may operate on the partial frequency band, the network configures the user equipment to operate on the partial frequency band, and the user equipment communicates with the network using the partial frequency band.

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: 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.
