Abstract: Methods and systems for controlling uplink (UL) transmission power of a user equipment (UE) electronic device includes determining, using the UE electronic device, that a maximum power availability for a transmission between the UE and a wireless network node is not appropriate to current conditions. Based on the determination that maximum power availability is not appropriate the UE electronic device sends a request to the wireless network node to reduce power for communication with the wireless network node. Based on the request, the UE electronic device communicates at a reduced power level for communications with the wireless network node.

Abstract: User equipment may transmit and receive wireless signals to and from various communication networks. Furthermore, user equipment may indicate usage capabilities to the various wireless communication networks to enable the user equipment to transmit and/or receive wireless signals to and from at least two different communication networks. In particular, the user equipment may indicate usage capabilities of supporting both Frequency Range 2 (FR2) wireless signals of a fifth generation (5G) network and 7-24 gigahertz (GHz) wireless signals of a sixth generation (6G) network in an intermediate frequency range of the user equipment. The communication network(s) may then configure and/or schedule the user equipment based on the usage capabilities to enable the user equipment to simultaneously or non-simultaneously communicate using both the FR2 wireless signals and the 7-24 GHz wireless signals while preventing interference in the intermediate frequency range of the user equipment.

Abstract: User equipment may transmit and receive wireless signals to and from communication networks. However, in close proximity, transmission signals from a first user equipment may interfere with wireless signals received by a second user equipment. In certain instances, the user equipment may establish a session via peer-to-peer technologies and coordinate timing for communication with the networks. For example, the user equipment may establish a sidelink having a frequency different from a frequency used for communication with the networks. The user equipment may prioritize communication to a first communication network over a second communications network or vice versa. The user equipment may also designate a network connector and relay communication with the networks through the network connector. Additionally or alternatively, the user equipment may share the task of determining a global position. Accordingly, the user equipment may reduce or eliminate signal interference and preserve battery power.

Abstract: An electronic device may be provided with wireless circuitry and control circuitry. The wireless circuitry may communicate with a wireless base station using a 5G New Radio (NR) communications protocol. The wireless circuitry may include a phased antenna array. The electronic device may perform antenna scaling operations in which the active antennas in the phased antenna array change over time to optimize wireless performance and power consumption. The electronic device may inform the base station when antenna scaling operations have occurred. This may allow the base station to compensate for power density discontinuities associated with the antenna scaling operations. If desired, the base station may break transmit and receive signal beam correspondence and the electronic device may use different antenna scaling settings for transmitting and receiving signals.

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 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 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: Methods and systems include beamformed wireless communications to and from a user equipment electronic device. During operation of the user equipment electronic device, a change in slot aggregation is made. Using the aggregated slots, the user equipment electronic device and/or a wireless network utilize beam sweeps to determine a best beam pairing by repeating a shared channel in the aggregated slots with a beam sweep of multiple beams between the user equipment electronic device and the wireless network.

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.
