  • Patent number: 12677114
    Abstract: This disclosure describes an architecture for supporting MBS sessions in a wireless access network. Each of such MBS sessions is flexibly and dynamically delivered by the access network into one or more Point-To-Point (PTP, or unicast) and Point-To-Multipoint (PTM, or multicast) delivery instances. As such, a subset of the UEs participating in the MBS may be configured to receive the MBS session in a PTP-like manner and quality. The architecture further allows for access network level switching of one or more of the UEs participating in the MBS session between the PTP mode and PTM mode. Such switching are effectuated dynamically without involvement of application layer. The resource allocations and configuration for the PTP and PTM delivery instances may be performed in the access network collaboratively between a central unit (CU) and one or more distributed units (DUs).

  • Patent number: 12566973
    Abstract: Approaches in accordance with various embodiments provide unified training and inference frameworks useful for co-training, and performing inferencing using, models such as language and graphing models. The frameworks can be hierarchical, in that an inner layer can include a language model for generating semantic embeddings from input text content, and these semantic embeddings can be passed as input to an outer layer that can generate graph labels based, at least in part, upon a knowledge graph having these semantic embeddings substituted for textual content. Nodes of a knowledge graph that are determined to be related to the input content can then be used for various purposes, such as to generate tags for the content or determine how to route that content.
