Claim 15:
16. User equipment (UE), comprising:
a processor; and
memory for storing instructions executable by the processor;
wherein the processor is configured to:
listen in to a first frequency band group, wherein the first frequency band group comprises p first frequency bands, and p is a positive integer;
listen in to a second frequency band group in response to determining that the p first frequency bands are all occupied, wherein the second frequency band group comprises q second frequency bands, and q is a positive integer;
wherein the p first frequency bands and the q second frequency bands are on an unlicensed spectrum, and a listening priority of the p first frequency bands is higher than the listening priority of the q second frequency bands;
wherein the processor is further configured to:
receive a listening frequency band set from a base station, wherein the listening frequency band set comprises at least two frequency bands on the unlicensed spectrum required to be listened by user equipment (UE), and the listening frequency band set comprises the p first frequency bands and the q second frequency bands;
after receiving the listening frequency band set from the base station, acquire the p first frequency bands from the listening frequency band set to form the first frequency band group; and
listen in to the first frequency band group;
wherein the processor is further configured to:
acquire priority information, wherein the priority information is used for indicating listening priorities of frequency bands included in the listening frequency band set;
in response to determining that the p first frequency bands are all occupied, acquire the q second frequency bands, the listening priority of which is lower than that of the p first frequency bands, from the listening frequency band set according to the priority information, so as to form the second frequency band group; and
listen in to the second frequency band group.
