Method and system for measuring a channel quality indicator, user equipment and base station

A user equipment, comprising:

• a processor, and
• a non-transitory processor-readable medium having processor-executable instructions stored thereon, the processor-executable instructions including processor-executable instructions for carrying out a method for obtaining multiple differing channel quality indicator (CQI) values, by the user equipment, according to distinct CQI configurations received from a base station, the method comprising:
• obtaining, by the user equipment from the base station, multiple CQI configurations comprising:
• a first CQI configuration indicating a signal carried in a resource is to be processed by the user equipment in a valid signal processing manner, and
• a second CQI configuration indicating a signal carried in the resource is to be processed by the user equipment in an interference signal processing manner;
• calculating, by the user equipment according to the multiple CQI configurations, multiple CQIs comprising:
• a first CQI calculated according to the first CQI configuration, wherein the signal carried in the resource is processed in the valid signal processing manner;
• and
• a second CQI calculated according to the second CQI configuration, wherein the signal carried in the resource is processed in the interference signal processing manner;
• and
• sending, by the user equipment, the first CQI and the second CQI to the base station,
• wherein the first CQI and the second CQI are used in a scheduling decision of the resource.

A base station, comprising:

• a processor, and
• a non-transitory processor-readable medium having processor-executable instructions stored thereon, the processor-executable instructions including instructions for carrying out a method for obtaining multiple differing channel quality indicator (CQI) values from a same user equipment, according to distinct CQI configurations provided by the base station, the method comprising:
• determining, by the base station for the user equipment, multiple CQI configurations comprising:
• a first CQI configuration indicating a signal carried in a resource is to be processed by the user equipment in a valid signal processing manner, and
• a second CQI configuration indicating a signal carried in the resource is to be processed by the user equipment in an interference signal processing manner;
• indicating the first CQI configuration and the second CQI configuration to the user equipment;
• and
• receiving, by the base station from the user equipment, multiple CQIs comprising:
• a first CQI calculated according to the first CQI configuration, wherein the signal carried in the resource is processed in the valid signal processing manner;
• and
• a second CQI calculated according to the second CQI configuration, wherein the signal carried in the resource is processed in the interference signal processing manner,
• wherein the first CQI and the second CQI are used in a scheduling decision of the resource.
