Abstract: A user equipment (UE) configured for carrier frequency operations above 52.6 GHz may decode radio-resource control (RRC) signalling received from a gNodeB (gNB) to configure the UE with a number of resource blocks (RBs) (NRB) for a physical uplink control channel (PUCCH) resource for each of one or more enhanced PUCCH formats. The one or more enhanced PUCCH formats may include enhanced PUCCH format 0, enhanced PUCCH format 1 and enhanced PUCCH format 4. The number of RBs may be configurable to be more than one for the enhanced PUCCH format 0, the enhanced PUCCH format 1 and the enhanced PUCCH format 4. The UE may encode an enhanced PUCCH format for transmission in accordance with one of the enhanced PUCCH format 0, the enhanced PUCCH format 1 and the enhanced PUCCH format 4. The enhanced PUCCH format may be transmitted to occupy the number of RBs that are configured.

Abstract: A triboelectric generator can include respective contact members including a first contact member and second contact member. The respective contact members can be movable with respect to each other such that the respective contact members separate from each other in a first configuration and contact each other in a second configuration. The first contact member can include a first conductive layer and a contact layer. The second contact member can be spaced apart from the first contact member in the first configuration and can include an insulating contact layer and a second conductive layer. The insulating contact layer can be configured to come into contact with the contact layer of the first contact member and the transition of the respective contact members from the first configuration to the second configuration can create triboelectric charges. In some examples, the first contact member can include a non-contact insulating layer.
