501, an interference level is determined in the first base station in multiple interference levels.

Wherein, described multiple interference level represents respectively subscriber equipment multiple annoyance levels to the second base station in the time sending upward signal to the first base station.

The first base station determines that in multiple interference levels an interference level has various ways.

For example, described the first base station receives the second base station of user equipment to report to the received signal quality of subscriber equipment, and in multiple interference levels, determines a described interference level according to described received signal quality.Concrete, described the first base station receives the second base station A that described subscriber equipment 1,2,3,4,5,6,7,8,9,10 reports, B, the C received signal quality to each subscriber equipment, and according to described received signal quality, determine the path loss of described each subscriber equipment to described each the second base station.Described the first base station receives the transmitting power balance information of described each user equipment to report, and obtains the transmitting power of described each subscriber equipment according to described transmitting power balance information.Described the first base station to the path loss of described each the second base station and the transmitting power of described each subscriber equipment, obtains the interference level of described each subscriber equipment to the second base station A, B, C according to the described each subscriber equipment obtaining.When there being subscriber equipment to send when upward signal to described the first base station, described the first base station can be according to described subscriber equipment the annoyance level to each the second base station, in multiple interference levels, determine an interference level for each the second base station.

Optionally, a described interference level definite interference level in multiple interference levels that described the first base station can also send by receiving the second base station, a described interference level is that the second base station is determined from multiple interference levels according to the measuring reference signals of the described subscriber equipment of described the second base station measurement.Concrete, the current user equipment in described the first base station instruction coverage sends measuring reference signals on the running time-frequency resource of specifying.Described the second base station A, B, C receive after described measuring reference signals, the running time-frequency resource shared according to described measuring reference signals, on corresponding running time-frequency resource, measure described measuring reference signals and obtain described subscriber equipment to described each the second base station interference level, and each described interference level is sent to described the first base station.When there being subscriber equipment to send when upward signal to described the first base station, described the first base station can be according to described subscriber equipment the annoyance level to each the second base station, in multiple interference levels, determine an interference level for each the second base station.

For instance, the interference level of 1,2,3,4,5,6,7,8,9,10 couples of the second base station A of subscriber equipment is respectively :-76 ,-76 ,-70 ,-82 ,-93 ,-114 ,-123 ,-131 ,-134 ,-130.The interference level of 1,2,3,4,5,6,7,8,9,10 couples of the second base station B of subscriber equipment is respectively :-89 ,-90 ,-110 ,-65 ,-70 ,-74 ,-128 ,-132 ,-134 ,-134.The interference level of 1,2,3,4,5,6,7,8,9,10 couples of the second base station C of subscriber equipment is respectively :-122 ,-126 ,-131 ,-90 ,-91 ,-112 ,-60 ,-63 ,-76 ,-73.

In the time having multiple the second base station, because same subscriber equipment is in the time sending upward signal to the first base station, the annoyance level that the second different base stations is formed is not necessarily identical, therefore, described each running time-frequency resource, for the second different base stations, has different interference levels.

The corresponding relation of multiple multiple interference level and multiple running time-frequency resources, according to interference level and running time-frequency resource, can be determined in described the first base station.

Taking multiple interference levels as strong jamming level, moderate interference level and weak jamming level, it is example that running time-frequency resource is divided into sub-frame resources according to subframe, the corresponding relation of multiple interference levels and multiple sub-frame resources can be: taking 6 subframes as one-period, for each cycle, according to being strong jamming level to the interference level of the second base station B, be moderate interference level to the interference level of the second base station C, be weak jamming level to the interference level of the second base station D, be strong jamming level to the interference level of the second base station B, be weak jamming level to the interference level of the second base station C, be moderate interference level to the interference level of the second base station D, be moderate interference level to the interference level of the second base station B, be strong jamming level to the interference level of the second base station C, be weak jamming level to the interference level of the second base station D, be moderate interference level to the interference level of the second base station B, be weak jamming level to the interference level of the second base station C, be moderate interference level to the interference level of the second base station D, be weak jamming level to the interference level of the second base station B, be strong jamming level to the interference level of the second base station C, be moderate interference level to the interference level of the second base station D, be weak jamming level to the interference level of the second base station B, be moderate interference level to the interference level of the second base station C, the order that is strong jamming level to the interference level of the second base station D is user equipment allocation sub-frame resources.
