User scheduling method, master base station, user equipment, and heterogeneous network

摘要

The present invention provides a user scheduling method, a master base station, a user equipment, and a heterogeneous network. The method includes: receiving, by a master base station, a downlink interference indicator DII forwarded by a serving slave base station serving a user equipment UE, where the DII is sent to the serving slave base station by the UE attached to the serving slave base station, and when the DII is greater than a preset threshold, the DII indicates that the UE is in a high DII region; determining, according to the DII, whether the UE is in a high DII region; and if the UE is in a high DII region, allocating, when performing scheduling, fewer resources that may interfere with the UE.

主权项

1. A user equipment scheduling method, comprising:
receiving, by a master base station, a downlink interference indicator (DII) from a serving slave base station corresponding to a user equipment (UE), and receiving a base station identifier corresponding to the DII; determining, by the master base station, based on the DII being greater than a preset threshold, that the UE is in a high downlink interference region; obtaining, by the master base station, according to the DII, an identifier of a base station that causes greatest interference to the UE; determining, according to the identifier of the base station that causes greatest interference to the UE, whether the master base station or an interfering slave base station causes greatest interference to the UE, wherein the interfering slave base station is another slave base station other than the serving slave base station; and allocating, by the master base station, in response to determining that the UE is in a high downlink interference region and in response to determining that the master base station causes greatest interference to the UE, fewer resources that may interfere with the UE when performing scheduling.
