Abstract: A piston ring with a coated outer surface is provided. The coating is disposed on end sections of the outer surface adjacent a gap. Typically, a middle section of the outer surface located between the end sections is not coated. The coating can be formed of CrN or DLC, and the CrN coating can be applied by physical vapor deposition (PVD). The end sections of the outer surface, upon which the coating is applied, are rough. For example, the outer surface can be blasted or otherwise textured to achieve the rough surface. The rough surface retains oil and distributes stress better than a smooth surface, and thus reduces crazing and flaking of the coating.

Abstract: In wireless communication systems using a subband full duplex carrier, a single slot may include one or more uplink (UL) portions and/or one or more downlink (DL) portions. In a case where a scheduler operating in a 3GPP New Radio (NR) network utilizes a Type 0 or Type 1 resource allocation, part of the DL allocation may fall within the UL portion of the carrier designated by the slot format, or vice versa. User equipment (a UE) may perform a logical operation that identifies, as a usable downlink resource allocation, a set of resource blocks belonging to both a given UL/DL resource allocation and a set of resources designated for UL/DL transmission in the slot format.
