  • Publication number: 20240064601
    Abstract: According to embodiments of the present disclosure, a first device receives first information from a second device. The first information is associated with a conditional handover through a source Integrated Access Backhaul (IAB) node to a target IAB node. If the conditional handover is completed at an ancestor IAB node, the first device transmits, to the second device, second information associated with the conditional handover. In this way, it avoids the child IAB node performs the handover before its parent IAB node.

  • Publication number: 20240049098
    Abstract: Embodiments of the present disclosure provide a solution for supporting a successful handover report. In a method for communication, a terminal device receives, from a first network device providing a first cell, an indication that a handover of the terminal device from the first cell to a second cell of a second network device is to be performed. Then, the terminal device determines triggering information about a successful handover report of the handover based on a set of triggering conditions. The triggering information indicates whether the successful handover report is triggered for the handover. In this way, the successful handover report can be optionally triggered based on the set of triggering conditions, so that the terminal device may be limited to reporting a successful handover report when necessary, thereby saving processing resources and communication resources for unnecessary successful handover reports.

  • Publication number: 20230382085
    Abstract: An electronic device may have optical components that each have first and second transparent layers such as first and second glass layers. The glass layers may have outer surfaces that face away from each other and inner surfaces that face towards each other. A polymer layer is formed between the inner surfaces of the glass layers. Along the periphery of each optical component, a hermetic seal is formed to protect the polymer material of the polymer layer. The seal may have a moisture barrier layer that is attached to the first and second glass layers. The moisture barrier layer may be supported by an elastomeric buffer member. The moisture barrier layer may be formed from metal film or a polymer layer or other substrate that is coated with a moisture-impermeable coating. The moisture-impermeable coating may be formed from one or more thin-film metal layers and/or one more thin-film dielectric layers.

  • Publication number: 20230371079
    Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A network device transmits, to a terminal device, a configuration of bandwidth part for transmission of uplink data in an inactive state, the configuration comprising a configured grant. When the terminal device decides to transmit the uplink data in the inactive state, the terminal device determines the configured grant from the configuration of bandwidth part, and transmits, in the inactive state, the uplink data to the network device based on the configured grant. In this way, configuration grant based small data transmission can be enhanced.

  • Patent number: 11813048
    Abstract: A system and method is provided for acquiring flow encoded data from a subject using a magnetic resonance imaging (MRI) system. The method includes acquiring flow encoded (FE) data with alternating encoding polarities and along two of three orthogonal directions through the subject over at least two cycles of the flow within the subject; and separating the FE data into directional FE datasets using a temporal filter that separates the FE data based on temporal modulation of the FE directions caused by the alternating encoding polarities extending over the at least two cycles of the flow within the subject that shift the Fourier spectrum of velocity waveforms corresponding to the FE data. The method also includes using the directional FE datasets to generate an image of the subject showing flow within the subject caused by the at least two cycles of flow within the subject.

  • Publication number: 20230284315
    Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A method comprises a terminal device determines whether one or more DRBs with uplink data to be transmitted support SDT. If the one or more DRBs support the SDT, the terminal device determines whether the uplink data is to be transmitted in the inactive state. If the uplink data is to be transmitted in the inactive state, the terminal device transmits the uplink data to a first network device in the inactive state. Upon receipt of the uplink data, the first network device transmits to a third network device a request for relocating an anchor for a context of the terminal device, the request comprising a first indication as to whether there is remaining data to be transmitted. In this way, an enhanced mechanism for SDT is achieved and lossless transmission for SDT is attained.
