Resource Scheduling Method, Radio Access Device, and Communications System

A radio access device comprising:

• a first measuring module configured to measure an interference parameter value corresponding to each uplink resource block of a first communications system, wherein the interference parameter value is used to represent a degree of interference on a receive end of a second communications system when a terminal of the first communications system transmits data on a corresponding uplink resource block;
• a second measuring module configured to measure a channel condition parameter value of an uplink channel of the first terminal when a first terminal accessing the first communications system needs to transmit uplink data, wherein the channel condition parameter value is used to represent a current channel condition of the uplink channel of the first terminal;
• and
• a first resource scheduling module configured to preferentially allocate an uplink resource block meeting a first scheduling condition for the first terminal to transmit the uplink data when the second measuring module measures that the channel condition parameter value of the uplink channel of the first terminal is greater than a first channel condition threshold, and preferentially allocate an uplink resource block meeting a second scheduling condition for the first terminal to transmit the uplink data when a current channel condition parameter value of the uplink channel of the first terminal is less than the first channel condition threshold, wherein the uplink resource block meeting the first scheduling condition is an uplink resource block, whose interference parameter value measured by the first measuring module is greater than a first interference threshold, of the first communications system, and the uplink resource block meeting the second scheduling condition is an uplink resource block, whose interference parameter value measured by the first measuring module is less than the first interference threshold, of the first communications system.

A radio access device comprising:

• a third resource scheduling module configured to allocate a downlink resource block of a first communications system to a third terminal accessing the first communications system;
• and
• a fourth resource scheduling module configured to:
• when the third terminal further needs to transmit uplink data, preferentially allocate an uplink resource block, away from the downlink resource block allocated by the third resource scheduling module as far as possible in frequency, in an uplink frequency band of the first communications system for the third terminal to transmit the uplink data.

A radio access device, comprising:

• a fifth resource scheduling module, configured to allocate an uplink resource block of a first communications system to a fourth terminal accessing the first communications system;
• and
• a sixth resource scheduling module, configured to:
• when downlink data further needs to be transmitted to the fourth terminal, preferentially allocate a downlink resource block, away from the uplink resource block allocated by the fifth resource scheduling module as far as possible in frequency, in a downlink frequency band of the first communications system to transmit the downlink data to the fourth terminal.
