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: Various embodiments are described for apparatuses, systems, and methods for pre-forwarding data packets for conditional handover. A UE may connect to a serving base station and perform measurement(s) of one or more neighboring base stations. The UE may provide measurement report(s) corresponding to the measurement(s) to the serving base station. The UE may receive handover assistance information from the serving base station. The handover assistance information may identify at least one neighboring base station that receives downlink packet forwarding of downlink packets intended for the UE prior to handover. The UE may evaluate handover conditions of the neighboring base stations, including the at least one neighboring base station. The UE may perform handover to a first neighboring base station of the at least one neighboring base station based on the at least one neighboring base station receiving downlink packet forwarding of downlink packets intended for the UE prior to handover.

Abstract: Systems and methods related to partial beam correspondence may be used to address potential limitations of beamforming wireless networks. A user equipment electronic device and/or wireless network identifies a subset of available transmitter beams for the user equipment electronic device that are indicated as similar to a downlink reference signal received at the user equipment electronic device from a wireless network node. The user equipment electronic device sweeps the subset of available transmitter beams for communication with the wireless network node and uses a best beam from the sweep to communicate with the wireless network node.

Abstract: An electronic device may be provided with wireless circuitry and control circuitry. The wireless circuitry may communicate using a 5G New Radio (NR) protocol. The wireless circuitry may have multiple bandwidth part configurations. The control circuitry may place the wireless circuitry in a first bandwidth part configuration where a first bandwidth part of a first component carrier is active and a second bandwidth part of a second component carrier is inactive. The control circuitry may switch the wireless circuitry from the first bandwidth part configuration to a second bandwidth part configuration in which the first bandwidth part is inactive and the second bandwidth part is active. The first and second component carriers may be intra-band contiguous, intra-band non-contiguous, or inter-band. The control circuitry may switch the wireless circuitry into other configurations for covering other bandwidth parts of any desired component carriers in any desired bands.

Abstract: An electronic device may be provided with wireless circuitry and control circuitry. The wireless circuitry may include a phased antenna array. Sensors and other circuitry in the electronic device may generate sensor data such as accelerometer data, gyroscope data, magnetometer data, location data, and spatial ranging data. The wireless circuitry may establish and maintain one or more wireless links with external devices based on the sensor data as the device moves over time. For example, the wireless circuitry may perform physical layer beam adjustments, inter-radio access technology handovers, intra-radio access technology handovers, and/or dual connectivity adjustments based on the sensor data. This may allow the device to maintain one or more wireless links without having to sweep the signal beam of the phased antenna array over its entire field of view each time the device has moved.
