  • Publication number: 20250175296
    Abstract: User Equipments (UEs) may be assigned a set of aggregated component carriers for downlink carrier aggregation and/or carrier selection. Some UEs may be incapable of transmitting uplink signals over all component carriers in their assigned set of aggregated component carriers. In such scenarios, a UE may need to perform SRS switching in order to transmit SRS symbols over all of the component carriers. Embodiments of this disclosure provide various techniques for facilitating SRS switching. For example, a radio resource control (RRC) message may be used to signal a periodic SRS configuration parameter. As another example, a downlink control indication (DCI) message may be used to signal an aperiodic SRS configuration parameter. Many other examples are also provided.

  • Patent number: 12310530
    Abstract: Provided is a system (100) for determining the main ingredients of a food recipe. The system comprises a first input (102) for receiving the identity and mass fraction (wri) of each ingredient (i) in the food recipe (r), and a second input (104) for receiving the identity of ingredients of each known recipe of a population of known recipes. The system further includes a controller (106) configured to calculate, for each ingredient (i), the fraction (P(i)) of the population which uses the ingredient. The controller then calculates, using the fraction (P(i)) and the mass fraction (wri), a value (Vri) which positively correlates with the mass fraction (wri) and negatively correlates with the fraction (P(i)). The main ingredients are then determined according to the ingredients which have values (Vri) equal to or greater than a threshold value.
