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: Embodiments herein provide various apparatuses and techniques that indicate multiple power classes that user equipment may support to a network. The user equipment may support at least a lower power class (e.g., having a lower maximum transmission power) and a higher power class (e.g., having a higher maximum transmission power) to the network. The user equipment may send indications to the network that it supports both the lower power class and the higher power class. If the network/user equipment are in a geographical region associated with regulations limiting transmission power to the lower maximum transmission power, then the network may configure a transmission power characteristic based on the lower power class. If the network/user equipment are in a geographical region associated with regulations limiting transmission power to the higher maximum transmission power, then the network may configure the transmission power characteristic based on the higher power class.

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: User equipment may include a transmitter coupled to an antenna to enable the user equipment to transmit data with a communication node and/or a non-terrestrial network. The user equipment may transmit using high power over a period of time such that the transmission power of the user equipment is below an emission threshold. For example, the user equipment may adjust a buffer status report to reduce uplink allocation frequency. In another example, the user equipment may determine a duty cycle and transmit the data using high power based on the duty cycle. In another example, the user equipment may determine a priority of uplink symbols and transmit certain uplink symbols using high power. In this way, the user equipment may transmit using high power and may improve transmission range to the non-terrestrial network and/or a likelihood that transmissions may be received by the network while remaining within the emission threshold.

Abstract: User equipment to transmit signals (e.g., concurrently) using multiple SIMs. If the user equipment determines to perform transmission power back-off due to operating using the multiple SIMs (MuSIM operation), the user equipment sends an indication to each network corresponding to each SIM that it is performing the power back-off. If a network supports MuSIM operation, then the user equipment sends an indication that it is performing the power back-off due to MuSIM operation (e.g., an MuSIM Maximum Power Reduction (M-MPR) indication). For such a network, it is assumed that the M-MPR indication would be standardized under an applicable specification. If a network does not support MuSIM operation (e.g., a legacy network), then the user equipment leverages a legacy power back-off indication (e.g., a Power Management Maximum Power Reduction (P-MPR) indication) to indicate to the network that it is performing a power back-off.

Abstract: A communication system may include user equipment (UE) communicatively coupled to one or more base stations. The UE and/or the one or more base stations may receive an indication of self-interference at the UE. This indication may be based on a receiver of the UE (e.g., a receive signal quality, a receive signal power, and so on), a transmitter of the UE (e.g., a transmission power), an estimate of self-interference, and so on. If there is sufficient self-interference (e.g., if the self-interference exceeds a threshold), then the one or more base stations may configure the UE for non-simultaneous receive/transmit operation to avoid transmission interfering with reception. If there is a lack of self-interference (e.g., if the self-interference does not exceed the threshold), then the one or more base stations may configure the UE for simultaneous receive/transmit operation, as transmission is unlikely to interfere with reception.
