  • Publication number: 20240023072
    Abstract: Methods, systems, and devices for wireless communications are described. A network entity may jointly configure a user equipment (UE) with time and frequency resources for full duplex communications. For instance, the network entity may provide a time resource pattern to the UE indicating a sequence of types of time resources, and the sequence of types may include a first type configuring resources for uplink and downlink communications in a first time resource. A configuration for the first type of the first time resource may indicate a first portion of frequency resources allocated for downlink communications and a second portion of frequency resources allocated for uplink communications. Thus, the UE may receive downlink signals on the first portion of frequency resources in the first time resource, and the UE may transmit uplink signals on the second portion of frequency resources in the first time resource.

  • Patent number: 11877307
    Abstract: Systems, methods, and devices for wireless communication that support mechanisms signaling non-linearities to a victim user equipment (UE) for interference cancellation in a wireless communication system. A victim UE may experience interference from an uplink transmission by an aggressor UE to a base station. The victim UE may obtain a power amplifier model associated with the aggressor UE. The power amplifier may include a non-linearity model of a power amplifier of the aggressor UE causing the interference on the victim UE. The power amplifier model obtained by the victim UE may be dependent on various parameters, such as a transmit power used by the aggressor UE to transmit the uplink transmission causing the interference. Based on the aggressor UE transmit power, the victim UE may select parameters for power amplifier model and may estimate the interference caused by the uplink transmission for interference cancellation.

  • Publication number: 20240012826
    Abstract: A method and apparatus for optimizing a query in a relational database management system (RDBMS) when a predicate on a data column in the query has a correlation to a partitioning attribute of a partitioning column in data retrieved from a cloud-based store, wherein the optimizing uses the correlation between the data column in the query to the partitioning column in the data retrieved from the cloud-based store for data elimination when processing the query. The correlation is defined in a formula or lookup data structure that maps or range-maps from the data column to the partitioning column.

  • Patent number: 11864126
    Abstract: Aspects presented herein may enable FD devices to apply power backoff and/or power allocation prioritization rules that are specific to FD transmissions. In one aspect, a UE determines an FD specific power backoff associated with each of at least one transmission of a plurality of transmissions in a slot that is configured as an FD slot, each FD specific power backoff is based on whether a corresponding transmission would cause self-interference with a DL reception in the FD slot, and the plurality of transmissions are overlapping in time. The UE determines a transmission power for each of the at least one transmission in the FD slot based on the determined FD specific power backoff for each of the at least one transmission. The UE transmits one or more of the at least one transmission based on the determined transmission power for the corresponding transmission.

  • Publication number: 20230388207
    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.

  • Publication number: 20230388837
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit channel state information (CSI) that is based on an estimated cross link interference (CLI) at the UE. For example, a network node may transmit a control message to a first UE that indicates one or more candidate precoding matrices associated with uplink precoding at a second UE. The first UE may receive a CSI-reference signal (CSI-RS) associated with estimation of a channel between the first UE and the network node and may receive a CLI-reference signal (CLI-RS) associated with estimation of a CLI channel between the first UE and the second UE. The bandwidth of the CLI-RS may be based on a measurement rule. The first UE may generate CSI based on the CSI-RS, the CLI channel, and one or more of the candidate precoding matrices and transmit a CSI report including the CSI.
