  • Publication number: 20230354073
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first message indicating a cross-link interference report configuration. The cross-link interference report configuration may be associated with a first set of rules for determining a quantity of resources for multiplexing a cross-link interference report on a physical uplink channel and a second set of rules for multiplexing the cross-link interference report on the physical uplink channel over the quantity of resources. The UE may transmit the cross-link interference report on the physical uplink channel in accordance with the first set of rules and the second set of rules. The cross-link interference report may indicate one or more cross-link interference measurements performed by the UE.

  • Publication number: 20230354074
    Abstract: Methods, systems, and devices for wireless communications are described. In one aspect, a UE may report channel state feedback (CSF) to a network entity based on channel state information (CSI) measurements and CLI measurements. In another aspect, a UE may explicitly report CLI measurements to a network entity. In yet another aspect, a UE may report a signal-to-interference-plus-noise ratio (SINR) to a network entity based on CLI measurements, and the network entity may trigger the UE to perform further CLI measurements on signals received from other UEs based on the SINR. In yet another aspect, a UE may generate a report using CLI measurements based on whether the UE is allocated enough time to generate and transmit the report. In yet another aspect, a UE may identify a suitable priority for reporting CLI to a network entity.

  • Publication number: 20230344122
    Abstract: Certain aspects relate to techniques for z-axis rotation estimation for compensating signaling transmitted between two or more nodes over a wireless channel where an antenna array of at least one of the nodes is misaligned about the z-axis relative to another node. For example, a transmitting node may transmit pilot signals defined by phase shifts to provide a receiving node with a basis for estimating the angle of rotation by which the antenna arrays are misaligned. The transmitting node may then take remedial action to address the misalignment based on the estimation.

  • Publication number: 20230336450
    Abstract: Techniques for optimizing technologies related to network path tracing and network delay measurements are described herein. Some of the techniques may include using an IPv6 header option and/or segment identifier field of a segment list or a TLV of a segment routing header as a telemetry data carrier. The techniques may also include using an SRv6 micro-segment (uSID) instruction to indicate to a node of a network that the node is to perform one or more path tracing actions and encapsulating the packet and forward. Additionally, the techniques may include using short interface identifiers corresponding to node interfaces to trace a packet path through a network. Further, the techniques may include using short timestamps to determine delay measurements associated with sending a packet through a network. In various examples, the techniques described above and herein may be used with each other to optimize network path tracing and delay measurement techniques.

  • Patent number: 11792214
    Abstract: A first dataset that includes an indication of a plurality of network events associated with a time-period is received. For each time sub-period from a plurality of time sub-periods that together span the time-period and to generate a second dataset, a value for each network event from the plurality of network events that occur within that time sub-period is summed. A discrete Fourier transform is performed based on the second dataset to generate a third dataset that includes an indication of a plurality of frequency ranges and a plurality of magnitude values for the plurality of frequency ranges. Each frequency from the plurality of frequencies ranges is associated with a magnitude value from the plurality of magnitude values. A set of candidate frequencies from the plurality of frequencies determined to potentially cause periodic behavior is identified based on the plurality of frequency ranges and the plurality of magnitude values.

  • Publication number: 20230328560
    Abstract: A UE may receive a configuration of one or more SP resources for CLI and/or SI measurement, and receive, from the base station, a MAC-CE activating the configured one or more SP resources for CLI and/or SI measurements. The UE may measure the CLI and/or SI based on interference signal and report a CLI report, including the measured CLI and/or SI to the base station. The UE may estimate average CL based on an average transmission power of the interference signal over multiple slots from an aggressor UE, and the base station may use the estimated average CL to determine CLI for aggressor UE based on CLI reciprocity.

  • Publication number: 20230321951
    Abstract: The disclosure relates to multilayer laminate compositions including opposing first and second polymeric layers, typically with an intervening gas and/or moisture barrier layer. The first polymeric layer incudes a first polymer, which can be selected based on desired mechanical and/or chemical properties. The second polymeric layer is a heat-sealable analog of the first polymeric layer, and it can include a blend of the first polymer along with a second polymer having a lower melting temperature, or a second polymer that includes monomer units of the first polymer copolymerized with a second monomer to provide a lower melting temperature for the second polymer relative to the first polymer. The improved heat-sealing properties of the second polymeric layer permits convenient packaging of items, and the common polymeric components between the first and second polymeric layers facilitates recycling and reuse of the multilayer laminate composition because of its substantially unimaterial nature.

  • Publication number: 20230328703
    Abstract: This disclosure provides methods, devices, and systems for full-duplex communications in wireless networks. Some implementations more specifically relate to multiple bandwidth parts (BWPs), active concurrently, for communications in a given direction (such as a downlink (DL) direction or an uplink (UL) direction) between a user equipment (UE) and a base station. For example, a first active BWP may be used for DL or UL communications in a half-duplex (HD) slot and a second active BWP may be used for DL or UL communications in an adjacent full-duplex (FD) slot. In some implementations, the UE may further change a status of one or more active BWPs after a given amount of time has elapsed. For example, the UE may change the states of an active BWP by deactivating the active BWP, switching the active BWP to a default BWP, or changing a role assigned to the active BWP.

  • Patent number: 11782925
    Abstract: In some examples, the database system maintains metadata for a plurality of data objects, the metadata containing ranges of values of an attribute for the plurality of data objects, where the ranges of values of the attribute comprise a respective range of values of the attribute for each corresponding data object of the plurality of data objects. The database system generates a data structure tracking quantities of ranges of values of the attribute that have a specified relationship with respect to corresponding different values of the attribute. The database system receives a database query comprising a predicate specifying a condition on a given value of the attribute, and computes, for the database query, a selectivity of filtering based on the metadata, the selectivity computed based on the data structure.

  • Publication number: 20230318797
    Abstract: A sidelink network is disclosed that provides a duplex mode indication as well as a duplex mode switching and coordination for a sidelink network device. The duplex mode indication controls the duplex mode switching by the sidelink network device between a half-duplex mode and a full-duplex mode of communication. The resulting control of the duplex mode switching reduces blocking and reduces power consumption.
