    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 is directed to techniques to facilitate power boosting for wireless communication devices (e.g., user equipment). The user equipment may be subject to specifications (e.g., the 3GPP specification) that require maximum power reduction (MPR) depending on the resource block allocation region in which the user equipment is operating. However, certain regions defined by the 3GPP specification may not facilitate transmission power boost as applied to shaped (e.g., modulated) transmissions. The techniques disclosed herein include defining the regions such that the MPR restrictions applied to the user equipment are reduced or minimized for allocations that enable power boosting. The regions may be defined using parameters based on a maximum number of resource blocks specified for a certain channel bandwidth, the amount of allocated resource blocks, and the resource block at which the allocation begins.

    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.

    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 may communicate with a wireless base station using a 5G New Radio communications protocol. The base station may balance control timing and receiver performance for the devices in its cell by scheduling communications based on the communications capabilities of each device. This may ensure that the base station is able to provide communications with satisfactory control timing and receiver performance even if multiple different types of device are within its cell. In addition, the device may perform open loop transmit power control operations and then closed loop power control operations. To minimize complexity of the device, the device may only transmit at a maximum output power level during the open loop operations. If desired, the device may only transmit at the maximum output power level when the device is unable to decode a downlink reference signal transmitted by the base station within a predetermined number of symbols.

    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.
