Method and apparatus for scheduling user equipment

摘要

Embodiments of the disclosure provide a method and apparatus for scheduling a UE, wherein a BS serves the UE and employs a non-normal subframe to coordinate inter-cell interference, and wherein transmission power in the non-normal subframe is lower than that in a normal subframe. In the method according to embodiments of the present invention, channel quality information for the non-normal subframe may be adjusted based on information on transmission power of downlink packets and reference signals; and a target MCS may be determined according to the adjusted channel quality information, so that the BS schedules the UE based on the target MCS in the non-normal subframe.

1. A method for scheduling a user equipment (UE), wherein a base station (BS) serves the UE and employs a first subframe to coordinate inter-cell interference, the first subframe having transmission power lower than that of a second subframe employed by the BS, the method comprising:
adjusting channel quality information for the first subframe based on information on transmission power of downlink packets and reference signals; and determining a target modulation and coding scheme (MCS) according to the adjusted channel quality information, so that the BS schedules the UE based on the target MCS in the first subframe, wherein the determining a target MCS according to the adjusted channel quality information comprises: selecting a candidate MCS from a CQI-MCS mapping table based on the adjusted channel quality information; and determining the target MCS based on the candidate MCS and a power control dynamic range, wherein the power control dynamic range comprises at least one dynamic level for at least one modulation mode, and wherein the determining the target MCS based on the candidate MCS and power control range comprises: comparing the power control range and the information on transmission power of downlink packets and reference signals; in response to that the information on transmission power of downlink packets and reference signals exceeds the power control range, determining a MCS with least requirements in the CQI-MCS mapping table as the target MCS; and in response to that the information on transmission power of downlink packets and reference signals does not exceed the power control range, if the information on transmission power of downlink packets and reference signals does not exceed the dynamic level for a modulation mode of the candidate MCS, determining the candidate MCS as the target MCS, and if the information on transmission power of downlink packets and reference signals exceeds the dynamic level for a modulation mode of the candidate MCS, determining a MCS with less requirements than the candidate MCS in the CQI-MCS mapping table as the target MCS, wherein the target MCS has different modulation mode from the candidate MCS.
