  • Publication number: 20240048342
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit control signaling scheduling a downlink transmission to a user equipment (UE) across multiple bandwidth parts (BWPs) and an indication of a code block group (CBG)-based mapping for the downlink transmission. A transport block (TB) of the downlink transmission may include multiple code block groups (CBGs) that are mapped across the BWPs. The UE may monitor for the TB across the BWPs based on the CBG mapping. For example, the UE may determine the CBGs are mapped across different BWPs based on the cross-BWP CBG mapping. Additionally or alternatively, the UE may determine each CBG is mapped within one BWP based on the cross-BWP CBG BWPs mapping. The UE may calculate a TB size based on available time and frequency resources and may decode the TB based on calculating the TB size and the cross-BWP CBG mapping.

  • Publication number: 20240041702
    Abstract: Base material arrangements having at least two layers can accommodate the addition of antifungal material (nanofiller), such as in denture base resin without significantly compromising the mechanical properties and/or translucency of the base material arrangements. Antifungal agents such as nanosilver and nanozirconia can be used to modify a surface layer of the material arrangements, such as the denture base, to overcome certain known shortcomings of the modified materials, e.g., typical acrylic resins containing nanosilver and nanozirconia.

  • Publication number: 20240049200
    Abstract: Aspects of the disclosure provide techniques for wireless communication using sub-band full duplex (SBFD). A network entity can inform a user equipment (UE) on the allocation of communication resources for SBFD operations using sub-bands. The network entity can indicate sub-band allocation in symbols/slots configured for SBFD operations using various techniques. A UE can receive a SBFD configuration of one or more time slots, each time slot including a plurality of symbols. The SBFD configuration indicates that one or more of the plurality of symbols are capable of an SBFD operation using a first sub-band for downlink (DL) communication and a second sub-band for uplink (UL) communication. The UE can communicate with the network entity in the one or more symbols configured for the SBFD operation using at least one of the first sub-band for DL communication or the second sub-band for UL communication.

  • Publication number: 20240049199
    Abstract: A method of wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE receives a resource allocation for a first set of resources in a first frequency band that is disjoint from a second frequency band in a sub-band full duplex (SBFD) slot, and communicates with a network node using the first set of resources in the first frequency band and a corresponding second set of resources in the second frequency band. The method improves the resource allocation efficiency for scheduling resources over multiple disjoint sub-bands.

  • Patent number: 11888786
    Abstract: Aspects are provided which allow a base station to configure flexible BWPs that include a dedicated slot format or may be applied in both DL and UL symbols, and which allow a UE to switch between flexible BWPs in frequency and/or time. The base station configures a first BWP and a second BWP. The first BWP is associated with a first bandwidth and a first slot format dedicated for the first BWP. The base station transmits, to a UE, a configuration to switch the first BWP to the second BWP. The UE receives the configuration from the base station and switches the first BWP to the second BWP. In particular, the UE may switch the first bandwidth to a second bandwidth, the first slot format to a second slot format, or both the first bandwidth and first slot format to the second bandwidth and second slot format, respectively.

  • Patent number: 11887383
    Abstract: Vehicle interior object management uses analysis for detection of an object within a vehicle. The object can include a cell phone, a computing device, a briefcase, a wallet, a purse, or luggage. The object can include a child or a pet. A distance between an occupant and the object can be calculated. The object can be within a reachable distance of the occupant. Two or more images of a vehicle interior are collected using imaging devices within the vehicle. The images are analyzed to detect an object within the vehicle. The object is classified. A level of interaction is estimated between an occupant of the vehicle and the object within the vehicle. The object can be determined to have been left behind once the occupant leaves the vehicle. A control element of the vehicle is changed based on the classifying and the level of interaction.

  • 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.
