Further, if the first preset range includes multiple values, or the second preset range includes multiple values, the first preset range is determined according to a type of data to be scheduled by the first base station, and the second preset The range is determined according to the type of data to be scheduled by the second base station. For example, high-priority data (such as voice data) generates random numbers in the range (0, 4), and low-priority data (such as Internet service data) generates random numbers in the range of (0, 8), that is, scheduling Higher The random number generated by the base station of the priority data is smaller.

In this embodiment, the second base station detects the first spectrum occupancy information sent by the first base station, and then the second base station does not receive the first spectrum occupancy information sent by the first base station, or the second base station receives the first The second base station passes the first spectrum scheduling data when the first spectrum occupation information sent by the base station is determined to be smaller than the second occupation priority of the second base station. Different base stations are configured to schedule data on the same spectrum, thereby reducing the interference of different base stations using the same spectrum, thereby improving spectrum utilization efficiency and system throughput.

Rate, etc., then, the second base station acquires first spectrum indicator information, the first The at least one indicator information includes at least one of the uplink and downlink channel quality of the channel corresponding to the first spectrum, and the uplink and downlink data transmission failure rate of the first spectrum corresponding channel.

Step 202: The second base station determines, according to the first spectrum indicator information, whether the first spectrum indicator is greater than a preset value.

Specifically, if the second base station determines that the first spectrum indicator is greater than the preset value, the second base station determines that the channel quality corresponding to the first spectrum is good, and then performs step 203, if the second base station determines that the first spectrum indicator is less than or equal to the pre- If the value is set, the second base station determines that the channel quality corresponding to the first spectrum is poor.

The second base station does not receive the first spectrum occupancy information sent by the first base station in the first duration, and determines to pass the first spectrum scheduling data at the end time of the first duration. At the same time, the second base station may send information to the UE that continues to use the first spectrum by means of broadcast and/or dedicated signaling, even if the channel corresponding to the first spectrum is used to schedule data, such as receiving data and transmitting data.
