Abstract
A base station and a related method are provided. The base station includes a transmitter which, in operation, transmits, to a user equipment (UE), values configured for different base station coordination types, respectively, wherein each of the base station coordination types defines which base stations among multiple base stations perform coordinated transmission in that base station coordination type. The base station further includes a receiver which, in operation, receives a channel quality indicator (CQI) reported from the UE, wherein the CQI is calculated at the UE in reference to the values.
Claims14
A method performed by a base station for receiving a channel quality indicator (CQI), the method comprising:
- setting a CQI adjustment value for a base station coordination type, the base station coordination type defining which base stations among a plurality of base stations perform coordinated transmission, the CQI adjustment value being set according to traffic loading conditions of the plurality of base stations;
- transmitting, to a user equipment (UE), the CQI adjustment value;
- receiving the CQI reported from the UE, the CQI being calculated at the UE in reference to the CQI adjustment value;
- and
- assigning a resource to the UE in reference to the received CQI.
A base station comprising:
- circuitry which, in operation, sets a channel quality indicator (CQI) adjustment value for a base station coordination type, the base station coordination type defining which base stations among a plurality of base stations perform coordinated transmission, the CQI adjustment value being set according to traffic loading conditions of the plurality of base stations;
- a transmitter which, in operation, transmits, to a user equipment (UE), the CQI adjustment value;
- and
- a receiver which, in operation, receives a CQI reported from the UE, the CQI being calculated at the UE in reference to the CQI adjustment value;
- and
- a scheduler which, in operation, assigns a resource to the UE in reference to the received CQI.
