Abstract
The present disclosure provides a method, a terminal and a base station for interference cancellation/mitigation/rejection in the presence of neighboring cell interference. The method provided by the present disclosure can effectively cancel/mitigate/reject interference of neighboring cells and improve the performance of a downlink transmission receiver by receiving configuration information (e.g., system assistant information) from a base station and performing interference processing based on the received configuration information.
Claims13
A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
- transmitting, to a base station, UE capability information for supporting a cell reference signal-interference mitigation (CRS-IM) associated with an assistance of a network signaling, wherein the UE capability information includes at least one of first information indicating that the UE supports a neighboring long term evolution (LTE) cell CRS-IM with the assistance of the network signaling or second information indicating that the UE supports the neighboring LTE cell CRS-IM without the assistance of the network signaling;
- receiving, from the base station, at least one configuration information on a LTE neighbor cell associated with a CRS;
- and
- performing the CRS-IM based on the at least one configuration information on the LTE neighbor cell associated with the CRS,
- wherein in case that the UE capability information includes the first information indicating that the UE supports a neighboring LTE cell CRS-IM with the assistance of the network signaling, the at least one configuration information on the LTE neighbor cell associated with the CRS includes information on a channel bandwidth.
