  • Patent number: 11962528
    Abstract: Certain aspects of the present disclosure provide techniques for channel state information (CSI) for multiple transmission reception point (multi-TRP) transmission such as non-coherent joint transmission (NCJT), including determining subband sizes for CSI and rules for Part II CSI omission. A method that can be performed by a user equipment (UE) includes receiving a CSI report configuration. The CSI report configuration associated with one or more CSI reference signal (RS) resources, each CSI resource including a set of ports or port groups. The UE selects one or more CSI-RS resources for which to report CSI and determines a subband size for sending a CSI report based, at least in part, on payload of the CSI report. In an example method, the UE can determine whether the UE has sufficient resources for the CSI report and omit at least a portion of the CSI based on the determination.

  • Patent number: 11960422
    Abstract: Systems, apparatuses and methods may provide for a frontend driver that notifies a hypervisor of a map request from a guest driver of a device, wherein the device is passed through to and directly controlled by a virtual machine, and wherein the map request is associated with an attempt of the device to access a guest memory page in a virtualized execution environment. The frontend driver may also determine whether the guest memory page is pinned and send a map hypercall to the hypervisor if the guest memory page is not pinned. Additionally, the hypervisor may determine that the guest memory page is pinned, determine, based on a direct memory access (DMA) bitmap, that an unmap request from the guest driver has been issued, and unpin the guest memory page.

  • Patent number: 11960549
    Abstract: Data is collected from a network graph, wherein the collected data is useful for training a machine learning model on a query domain. A domain-specific template corresponding to the query domain is received, the domain-specific template defining one or more classifiers to guide collection of content relevant to the query domain from the network graph. A collection starting point is analyzed based on the one or more classifiers of the domain-specific template to identify one or more relevant instances of the content. The one or more identified relevant instances of the content are added to a contextual protocol package. Each identified relevant instance of the content is analyzed based on the one or more classifiers of the domain-specific template to identify one or more additional relevant instances of the content. The one or more identified additional relevant instances of the content are added to the contextual protocol package.

  • Publication number: 20240120963
    Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may use partial frequency sounding with different frequency subhop patterns so that a portion (which may be referred to as a subhop) of configured sounding reference signal (SRS) resources (e.g., a hop) are sounded. In some cases, a UE may receive a control message from a network entity identifying the frequency subhop pattern. In some cases, the network entity may configure a UE to transmit repetitions of the SRS in a same hop across consecutive symbols to increase a probability that the transmissions are successfully received and decoded by the network entity. As such, the network entity may configure a repetition factor for the frequency subhop pattern. In some cases, the frequency subhop pattern may introduce a frequency overlap between subhops.
