  • Publication number: 20230076923
    Abstract: In order to perform a semantic search based on a graph database, sets of nodes are selected from a plurality of nodes in a graph database. A set of nodes semantically matches a keyword in a natural language query. At least one target node is identified in the sets of nodes. A path is selected from candidate paths based on similarities between the candidate paths and a plurality of paths in the graph database. A graph query for retrieving information from the graph database is generated based on the selected path and the query target.

  • Publication number: 20230065671
    Abstract: Aspects of the disclosure relate to inter-band carrier aggregation. A user equipment (UE), for example, may obtain a measured configured maximum UE output power (PUMAX) and prioritize aspects of UE transmissions that contribute to PUMAX. Prioritization may be based, for example, on band priority, channel priority, service priority, or any combination thereof. The power levels related to the prioritized features may be changed by changing a power management maximum power reduction (P-MPR) of each feature associated with the transmission according to the prioritized order of the features. The UE may determine if an electromagnetic power density exposure level of the UE is at or below a predetermined maximum permissible exposure (MPE) level. The UE may continue to reduce the transmitter output power if the electromagnetic power density exposure level is greater than the predetermined MPE level. Other aspects, embodiments, and features are also claimed and described.

  • Publication number: 20230069352
    Abstract: Various aspects relate to indicating bundling across carriers (e.g., across cells). In some aspects, bundling may involve sending information sent over multiple carriers (e.g., information sent from or to multiple cells) where the information sent over the carriers is combinable at a receiver. For example, a communication device may send the same set of information (e.g., transport blocks with the same content) via multiple carriers, send different redundancy versions of a set of information via different carriers, send information via different beams on different carriers, or send information using a combination of these techniques. The disclosure relates in some aspects to indicating whether bundling is applied across carriers. For example, downlink control information (DCI) that schedules transmissions on multiple carriers (e.g., multiple component carriers) may include an indication of whether bundling is applied across all or a subset of the scheduled carriers.
