  • Publication number: 20210105104
    Abstract: A first user equipment (UE) is configured to receive from a base station a signaling comprising indication of one or more time-frequency resources and an indicator indicating a time gap, and transmit a transport block (TB) to a second UE using the one or more time-frequency resources. For each of the time-frequency resources, the first UE monitors a hybrid automatic repeat request (HARQ) feedback from the second UE, using a physical sidelink feedback channel (PSFCH) resource; and transmits to the base station a HARQ feedback report signal based on the HARQ feedback or absence thereof, in a physical uplink control channel (PUCCH), using a single PUCCH resource determined based on the time gap from a last one of the PSFCH resources.

  • Patent number: 10937650
    Abstract: Methods of in situ fabrication and formation of horizontal nanowires for a semiconductor device employ non-catalytic selective area epitaxial growth to selectively grow a semiconductor material in a selective area opening of predefined asymmetrical geometry. The selective area opening is defined in a dielectric layer to expose a semiconductor layer underlying the dielectric layer. The non-catalytic selective area epitaxial growth is performed at a growth temperature sufficient to also in situ form a linear stress crack of nanoscale width that is nucleated from a location in a vicinity of the selective area opening and that propagates in a uniform direction along a crystal plane of the semiconductor layer in both the semiconductor layer and the dielectric layer as a linear nanogap template. The semiconductor material is further selectively grown to fill the linear nanogap template to in situ form the nanowire that is uniformly linear.
