Abstract: Methods of producing microrods for electron emitters and associated microrods and electron emitters. In one example, a method of producing a microrod for an electron emitter comprises providing a bulk crystal ingot, removing a first plate from the bulk crystal ingot, reducing a thickness of the first plate to produce a second plate, and milling the second plate to produce one or more microrods. In another example, a microrod for an electron emitter comprises a microrod tip region that comprises a nanoneedle that in turn comprises a nanorod and a nanoprotrusion tip. The microrod and the nanoneedle are integrally formed from a bulk crystal ingot by sequentially: (i) removing the microrod from the bulk crystal ingot; (ii) coarse processing the microrod tip region to produce the nanorod; and (iii) fine processing the nanorod to produce the nanoprotrusion tip.

Abstract: A method for providing scheduling request resources to a user equipment involves a wireless network node (e.g., an eNB) transmitting a configuration of scheduling request resources to the user equipment via radio resource control signaling, and the wireless network node enabling the scheduling request resources by transmitting a message to the user equipment via physical layer signaling. The message that enables the scheduling request resources may be transmitted as part of an uplink grant or downlink grant. In some implementations, the enabling message maps to one of several sets of scheduling request resources, which the wireless network node has previously communicated to the user equipment via radio resource control signaling. In other implementations, the selection of which set of scheduling request resources is to be enabling is made by the user equipment based on implicit signaling from the wireless node.
