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: 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: 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: 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: 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: A wireless network may include a base station and user equipment (UE). The UE and base station may perform initial access operations at frequencies greater than or equal to 57 GHz without the use of transmit power control (TPC) signals. The UE devices and the base station may also perform connected mode operations at these frequencies without the use of TPC signals. The UE may perform power saving operations without the use of TPC signals. The base station may handle communications for multiple UE devices in its cell by partitioning the UE into groups based on the estimated path loss for each UE. The base station may perform TDMA, OFDMA, or a combination of TDMA/OFDMA scheduling for the UE devices. Performing these communications without TPC signaling maximizes the amount of network resources available for other purposes, simplifies communication scheduling, and maximizes the efficiency of the network.

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.
