Abstract: The present disclosure discloses an organic electroluminescent compound, a composition, a light emitting device and an application. The organic electroluminescent compound is a compound M having a structure shown in Formula (2), and Formula (2) is: in Formula (2), X1-X14 are selected from N or CR8, and R8 is selected from hydrogen or deuterium; L is selected from a connecting bond, substituted or unsubstituted C6-C30 arylenyl, and substituted or unsubstituted C3-C30 heteroarylenyl; Ar8-Ar9 are each independently selected from substituted or unsubstituted C6-C30 aryl and substituted or unsubstituted C3-C30 heteroaryl; and substituents are selected from one of or a combination of two of deuterium, halogen, cyano, C1-C6 alkyl, C3-C30 cycloalkyl, C6-C30 aryl and C3-C30 heteroaryl.

Abstract: An interaction method is presented for interference coordination information between base stations, a method for mitigating cross-link interference between base stations, and a base station using abovementioned methods. The interaction method for interference coordination information between base stations comprises: determining a predetermined beam setup of a base station; establishing a beam index indicating each beam in the predetermined beam setup and its corresponding status; and transmitting the beam index to other base stations. The method for mitigating cross-link interference between base stations comprises: receiving beam-associated interference coordination information from other base stations; determining, based on the interference coordination information, beam-associated interference status information; and adjusting, based on the interference status information, a power and/or a modulation coding scheme of each beam.
