  • Publication number: 20240129759
    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, devices use machine learning (ML) models to support wireless communications. For example, a user equipment (UE) may download ML model information from a network to determine an ML model. The network may additionally configure a status reporting procedure, a fallback procedure, or both for the ML model. In some examples, based on a configuration, the UE may transmit a status report to a base station according to a reporting periodicity, a UE-based trigger, a network-based trigger, or some combination thereof. Additionally or alternatively, the UE may determine to fallback from operating using the ML model to operating in a second mode based on a fallback trigger. In some examples, to restore operating using a downloaded ML model, the UE may download an updated ML model or receive iterative updates to a previously downloaded ML model.

  • Publication number: 20240121035
    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a wireless device may In use non-uniformly distributed bits for amplitude mapping and uniformly distributed bits for sign mapping to support probabilistic constellation shaping (PCS) for transmission of a message. To provide a coding gain with one or more retransmissions of the message, the device may configure redundancy versions based on the non-uniform distribution of one or more symbols. In some examples, the device may include the same set of non-uniformly distributed systematic bits or at least a portion of non-uniformly distributed systematic bits in each redundancy version of the message. Additionally or alternatively, the device may use multiple modulation and coding scheme (MCS) values to modulate one or more of the redundancy versions, where a first MCS value is used to modulate non-uniformly distributed symbols and a second MCS value is used to modulate uniformly distributed symbols.

  • Publication number: 20240106565
    Abstract: Apparatus, methods, and computer-readable media for network coding for handover are disclosed herein. A base station (BS) transmits a first group of encoded packets to a first road side unit (RSU) over a first radio access network (RAN) interface. The BS initiates a handover procedure between the first RSU and a second RSU. The BS receives, from the first RSU, a release acknowledgment associated with the handover procedure and feedback associated with the first group of encoded packets. The BS transmits network coding level information to the second RSU over a second RAN interface based on the feedback. The network coding level information indicates a number of missing encoded packets within the first group of encoded packets for the second RSU to transmit to the UE. The BS transmits, to the UE, a second group of encoded packets associated with the number of missing encoded packets at the second RSU.

  • Publication number: 20240048287
    Abstract: Apparatus, methods, and computer-readable media for network coding for dual connectivity are disclosed herein. A base station (BS) sends encoded symbols from a first network coding layer to a first radio link control (RLC) layer and transmits, to a user equipment (UE), encoded data comprising the encoded symbols. The BS also transmits encoded data to a road side unit (RSU) for passing to the UE as a split transmission. The UE can receive encoded packets from the BS and RSU at a network coding layer via a second RLC layer. The UE recovers source packets from the encoded packets with a rateless network code at the network coding layer. The UE sequences the source packets into an ordered set of source packets at the network coding layer and sends the ordered set of source packets from the network coding layer to a packet data convergence protocol layer for processing.
