Abstract: To provide for power saving and the flexibility to activate a sufficient number of links without sacrificing link performance during a discontinuous reception (DRX) cycle, a method to selectively activate a subset of links is disclosed. The method includes a user equipment (UE) receiving an indication from a base station to use a subset of a plurality of antenna ports. The UE may enter a sleep mode as part of the DRX cycle. The UE may activate the subset of the plurality of antenna ports indicated during a part of the DRX cycle such as during periodic wake up intervals. The UE may monitor for communication from the base station during the part of the DRX cycle using the plurality of antenna ports. If the UE detects the communication, the device may activate one or more additional links to prepare for data communication during another part of the DRX cycle.

Abstract: A switch assembly for engaging a switch of an electronic device includes a rotatable knob having an axis of rotation, a pin mechanism engaged with the rotatable knob, and a slider body. The pin mechanism includes a pin, the pin being offset from the axis of rotation of the rotatable knob.
