Abstract: A user selection method includes: acquiring user feature information; determining user association information according to the user feature information; and selecting users according to the user association information and a preset condition.

Abstract: Provided are a channel state information transmission method, a channel state information receiving method, a signaling information transmission method, a node and a medium. The channel state information sending method is applied to a first communication node and includes the following. M downlink measurement reference signal resources are determined, where M is a positive integer greater than 1; one set of channel state information is determined according to the M downlink measurement reference signal resources; and the one set of channel state information is sent.

Abstract: A method for determining a quasi-co-location (QCL) relationship, applied to a first node, including: acquiring indication information; determining the QCL relationship between a first reference signal and a second reference signal according to the indication information; where the indication information includes QCL association information, first time window information and second time window information; the QCL association information includes the first reference signal having the QCL relationship with the second reference signal, and a QCL type.

Abstract: The disclosure discloses a method for co-production of gelling and emulsifying pectins from chicory/Jerusalem artichoke pulp, including raw material pretreatment, extraction, filtration, concentration, alcohol precipitation, and drying. According to the cell wall structure and tissue characteristics of chicory/Jerusalem artichoke pulp, the disclosure targetedly adopts the salt extraction and the dilute acid extraction to sequentially produce gelling and emulsifying pectin products. The gelling chicory/Jerusalem artichoke pectin has characteristics of simple molecular structure, high purity, low degree of acetylation (DA), and high gel strength; and the emulsifying chicory/Jerusalem artichoke pectin has excellent emulsifying properties. The extraction method for chicory/Jerusalem artichoke pectin in the disclosure can provide two types of pectin at the same time, broaden the application range of chicory/Jerusalem artichoke pectin, and improve the processing utilization of chicory/Jerusalem artichoke pulp.
