A communication method, wherein the method comprises: determining, by a first base station (100, 500), that the first base station (100, 500) is affected by atmospheric duct interference from a second base station (200, 600); and sending, by the first base station (100, 500), first information to the second base station (200, 600) through a core network (300, 700, 900), wherein the first information is used to indicate that the first base station (100, 500) is affected by the atmospheric duct interference from the second base station (200, 600), wherein the first information is carried in a target field; and characterised by that the target field comprises at least one or more of the following fields: a transport layer address field, an internet protocol security transport layer address field, and a general packet radio service tunneling protocol transport layer address field, wherein when the target field comprises the transport layer address field, the internet protocol security transport layer address field, or the general packet radio service tunneling protocol transport layer address field, the first information comprises a value of the transport layer address field, a value of the internet protocol security transport layer address field, or a value of the general packet radio service tunneling protocol transport layer address field; and the value of the transport layer address field, the value of the internet protocol security transport layer address field, or the value of the general packet radio service tunneling protocol transport layer address field is a first value, and the first value indicates that the first base station (100, 500) is affected by the atmospheric duct interference from the second base station (200, 600); or when the target field comprises two or three of the transport layer address field, the internet protocol security transport layer address field, and the general packet radio service tunneling protocol transport layer address field, the first information comprises two or three values in a value of the transport layer address field, a value of the internet protocol security transport layer address field, and a value of the general packet radio service tunneling protocol transport layer address field; and the two or three values in the value of the transport layer address field, the value of the internet protocol security transport layer address field, and the value of the general packet radio service tunneling protocol transport layer address field are each a second value, and the second value indicates that the first base station (100, 500) is affected by the atmospheric duct interference from the second base station (200, 600). determining, by a first base station (100, 500), that the first base station (100, 500) is affected by atmospheric duct interference from a second base station (200, 600);
