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 disclosed herein relate to techniques for determining a maximum sensitivity degradation (MSD) value at a user equipment (UE), and sending the value to a network for scheduling a frequency band combination for uplink and/or downlink communication. The network configures the frequency band combination for the UE, and determines whether there may be potential interference when the UE uses the frequency band combination. If so, then the network sends an indication to the UE to deactivate uplink transmission. The UE then determines reference sensitivity (REFSENS) of its receiver when the network does not send a downlink transmission on the frequency band combination. The UE sets its transmitter to transmit with a predetermined (e.g., maximum) transmission power, sends uplink transmissions, and determines an interference power when operating using the frequency band combination. The UE then determines the MSD value based on the REFSENS and the interference power.

Abstract: Reporting UL Tx DC sub-carrier location information may include decoding a radio resource control (RRC) message received from a base station. The RRC message may comprise a configuration for dynamically reporting uplink (UL) transmit (Tx) direct current (DC) sub-carrier location information. A change associated with at boast one previous UL Tx DC sub-carrier location may be determined to have occurred, thereby creating at least one new UL Tx DC sub-carrier location. In response to determining the change, a medium access control (MAC) control element (MAC CE) may be encoded for transmission to the base station. The MAC CE may include information corresponding to the at least one new UL Tx DC sub-carrier location.

Abstract: User equipment indicates its maximum aggregated bandwidth capability to a base station. The user equipment may also indicate a maximum bandwidth capability for each component carrier. Additionally or alternatively, the base station may assume that the maximum aggregated bandwidth capability is also supported by the user equipment for lower order carrier aggregation bandwidth classes having aggregated bandwidth upper limits greater than or equal to the maximum aggregated bandwidth capability. Further, the user equipment may indicate a maximum number of components carriers capable of supporting a maximum components carrier bandwidth. The user equipment may indicate the maximum aggregated bandwidth capability via a new signaling capability added to a standard (e.g., the Third Generation Partnership Project (3GPP) standard), or via existing signaling provided by the 3GPP standard, such as by using a frequency separation class signal.

Abstract: An electronic device may transmit a communication request to a base station having an indication of a number of its receive branches and an indication of whether the communication request is designated as an urgent service fulfillment. The base station may delay a denial of the communication request until receiving the indication of whether the communication request is designated as using the urgent service fulfillment to reduce a likelihood of prematurely rejecting the communication request. The base station may also handover the communication request to a base station that supports the urgent service fulfillment. The base station may also be barred from transferring the user equipment to a frequency layer preferred by the base station when the communication request of the user equipment is designated as an urgent service fulfillment.

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: Aggregated channel bandwidth classes that overlap in frequency are allocated for a fallback group. The fallback group may define an increased or maximum bandwidth of aggregated component carriers as allocated by a network. By enabling the aggregated channel bandwidth classes for a fallback group to overlap in frequency, for an available aggregated channel bandwidth, a first aggregated channel bandwidth class may be implemented using a first number of component carriers, and a second aggregated channel bandwidth class may be implemented using a second number of component carriers different from the first. The different number of component carriers may enable more flexibility to more fully utilize the available aggregated channel bandwidth for communication. The network may then allocate one of these aggregated channel bandwidth classes to user equipment that more fully utilizes the available aggregated channel bandwidth for communication
