Abstract: Wireless communications systems may support identification or determination of a common default beam for a component carrier (CC) group (e.g., such that all CCs of a CC group may be associated with a same default beam). For example, a CC group may be configured or established to include one or more CCs (e.g., for carrier aggregation), where each CC group may share a same analog beamformer. As such, a beam (e.g., a default uplink/downlink beam) may be established as default or common across CCs of a CC group (e.g., versus default beams being configured or established for individual CCs). Such an established default beam of a CC group (e.g., a default beam common to all CCs of a CC group) may include or refer to a default downlink shared channel beam, a default sounding reference signal (SRS) beam, a default downlink control channel beam, etc.

Abstract: Systems, methods, and instrumentalities for affine motion estimation for affine model-based video coding may be disclosed herein. A first motion vector (MV) set including one or more MVs may be derived for a first coding block. The MVs may be control point MVs (CPMVs) and the MVs may be derived by performing affine motion estimation (ME) associated with the first coding block. The first MV set may be added to a recently-estimated MV list. A head of the recently-estimated MV list may be set to the first MV set. The recently-estimated MV list may be empty or may contain one or more previously-added MV sets.

Abstract: A control circuit for an isolated power converter includes a first sensing circuit that senses a secondary side output voltage and produces a pulse wave modulation (PWM) signal having a duty cycle that is proportional to a value of the secondary side output voltage. The PWM is transferred across the converter isolation barrier to the primary side, and a primary side circuit receives the PWM signal and outputs a control signal. A controller determines the value of the secondary side output voltage from the control signal and uses the value to control primary side power switching devices of the isolated power converter to regulate the secondary side output voltage at a selected value.

Abstract: A modular connector with components that can be economically assembled to provide high signal integrity in a harsh environment. The connector includes an insulative housing bounding a mating interface, a conductive housing engaging a rear of the insulative housing and having tubes extending through the rear of the insulative housing to the mating interface, and lead assemblies disposed in respective tubes. The conductive housing has a channel extending from its top to its front. The insulative housing has a top extension extending beyond its rear, and a locking feature extending from its rear into the channel through the front of the conductive housing. A member is disposed in the channel and has opposite ends disposed in the top extension and locking feature of the insulative housing, respectively. Such a configuration prevents relative movement of components within the connector in a harsh environment and therefore provide more consistent signal paths.
