Abstract: Methods, systems, and devices for wireless communication are described. A UE may transmit a random-access message to a base station and receive at least a control channel portion of a response to the random-access message from the base station, where the response may also include a data channel portion. Using the techniques described herein, the UE may then manage flow control feedback reporting to the base station based on whether the data channel portion includes a radio resource control (RRC) message. For instance, the UE may report an acknowledgment for the response if the data channel portion does not include an RRC message and a TA timer at the UE is running (e.g., regardless of whether the UE is able to or attempts to decode the data channel portion, since the data channel portion may only include TA information which may not be useful to the UE).

A user equipment (UE) may assess a first beam quality of a first beam for communications with a network entity and a second beam quality of a second beam.

Based on the adjusted value of power hysteresis, the UE may switch from the first beam to the second beam if a difference between the second beam quality and the first beam quality is greater than the adjusted value of power hysteresis.

Abstract: Systems and methods for manufacturing stators for electric submersible pumps, where a stator core having an inner portion and an outer portion is formed. The inner portion has a plurality of teeth and outward-facing slots. Magnet wire coils are formed on the inner portion by holding the inner portion in a stationary position and using a linearly movable robotic arm to position the magnet wire in each slot while preventing the wire from sliding axially with respect to the stator and adjacent turns of the coil. After forming the magnet wire coils on the inner portion of the stator core, the outer portion of the stator core is press-fit onto the inner portion to close the slots. The magnet wire can thereby be positioned to maximize the fill factor of each slot and increase power density for a given temperature rise.
