  • Publication number: 20240121652
    Abstract: A method implemented by a Wireless Transmit/Receive Unit (WTRU) includes receiving a DeModulation Interference Measurement (DM-IM) resource, determining an interference measurement based on the DM-IM resource, and demodulating a received signal based on the interference measurement. An interference is suppressed based on the interference measurement. At least one DM-IM resource is located in a Physical Resource Block (PRB). The DM-IM resource is located in a PRB allocated for the WTRU. The DM-IM resource is a plurality of DM-IM resources which form a DM-IM pattern, and the DM-IM pattern is located on a Physical Downlink Shared Channel (PDSCH) and/or an enhanced Physical Downlink Shared Channel (E-PDSCH) of at least one Long Term Evolution (LTE) subframe. The DM-IM resources are different for different Physical Resource Blocks (PRB) in the LTE subframe. The DM-IM is located in a Long Term Evolution (LTE) Resource Block (RB), and the DM-IM pattern is adjusted.

  • Publication number: 20240107554
    Abstract: Systems, devices, and methods are disclosed for determining one or more clear channel assessment occasions. Techniques include performing one or more clear channel assessment (CCA) processes on a channel during the one or more CCA occasions to determine whether the channel is available at the one or more CCA occasion based on the one or more CCA processes. Techniques include sending the UL transmission in one or more UL subframes via the channel on at least a condition that the channel is determined to be available at the one or more CCA occasions. Techniques include performing the one or more CCA processes on the channel during another of the one or more CCA occasions on at least a condition that the channel is determined to be unavailable at a previous CCA occasion.

  • Publication number: 20240080701
    Abstract: A wireless transmit/receive unit (WTRU) may receive first measurement indication information indicating an activation of measurement reporting. The WTRU may determine a first set of resource elements (REs) based on the first measurement indication information. Further, the first set of REs may be associated with measurement-related time and frequency resources. Also, the WTRU may receive one or more measurement-related signals in the indicated first set of REs. Additionally, the WTRU may perform a measurement of each measurement-related signal. The WTRU may transmit, based on the first measurement indication information, a measurement report based on the measurement of each measurement-related signal. Further, the WTRU may receive second measurement indication information indicating a deactivation of measurement reporting.

  • Patent number: 5437687
    Abstract: A wet process with no heating for continuous transfer pattern printing of a cellulose fabric web or its blends by using a corona-treated plastic film as a pattern carrier web and a dye admixed with a thickening agent containing water-soluble and alcohol-soluble hydroxypropyl cellulose or polyvinyl pyrrolidone as ink.
