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 herein enable user equipment to indicate that it may operate in a transmission diversity mode, but may fall back to a single transmission mode for a lower power class. In particular, if the user equipment will not fall back to a single transmission mode for a lower power class, then the base station configures uplink resources for the user equipment based on the user equipment operating in the transmission diversity mode. Otherwise, the user equipment sends an indication to the base station that it will use the single transmission mode for the lower power class. The base station then configures uplink resources for the user equipment based on the user equipment operating in the transmission diversity mode for the higher power class, and configures the uplink resources for the user equipment based on the user equipment operating in the single transmission mode for the lower power class.

Abstract: A testing device determines an Effective Isotropic Radiated Power (EIRP) of a wanted signal at a beam-peak direction and a maximum Total Radiated Power (TRP) of the wanted signal. The testing device then determines a power difference (ΔP) between the EIRP of the wanted signal at the beam-peak direction and the maximum TRP of the wanted signal. The testing device determines EIRP of a spectral emission mask (SEM) at each measurement bandwidth step at the beam-peak direction. The testing device then determines TRP at each measurement bandwidth step by determining a difference between the EIRP of the SEM at that measurement bandwidth step and the power difference (ΔP). The testing device compares the TRP at each measurement bandwidth step to a SEM specification, and reports whether the SEM specification has been met.

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: 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: The present disclosure relates to devices, apparatuses, and methods for enhanced PHR reporting in support of UE antenna scaling. A wireless device, which comprises at least one antenna array each comprising a plurality of antenna elements may perform antenna scaling by activating or deactivating at least one of the plurality of antenna elements (with corresponding RF chains) of one or more antenna arrays. The wireless device may generate a power headroom (PHR) report based at least on a difference between beamforming gains obtained after the antenna scaling and before the antenna scaling. The wireless device may then send the PHR report to a base station in communication with the wireless device.
