Abstract
Disclosed are a method and a base station for mitigating self-interference in which, in a resource region for transmitting a plurality of downlink control channels, an overlap region is configured, the overlap region being a resource region from which the effects of self-interference due to an uplink communication of a terminal must be removed, and the information regarding the overlap region is transmitted to a terminal connected to a base station and communicating via FDR.
Claims19
A method of a base station (BS) mitigating self-interference in a full duplex radio (FDR) communication environment, the method comprising:
- receiving information from a user equipment (UE), the information related to self-interference cancellation capacity of the UE;
- setting an overlap region from resource regions for transmission of a plurality of downlink control channels, the overlap region corresponding to a resource region in which an influence of self-interference caused by uplink communication of the UE must be removed;
- and
- transmitting information related to the set overlap region to one or more UEs connected to the BS in order to perform FDR communication,
- wherein the overlap region is set based on the self-interference cancellation capacity with a size configured in inverse proportion to the self-interference cancellation capacity.
A method of a user equipment (UE) mitigating self-interference in a full duplex radio (FDR) communication environment, the method comprising:
- transmitting information to a base station (BS), the information related to self-interference cancellation capacity of the UE;
- receiving information from the BS, the information related to a set overlap region corresponding to a resource region among resource regions for transmission of a plurality of downlink control channels in which an influence of self-interference caused by uplink communication to the BS must be removed;
- and
- mitigating the self-interference from a resource region corresponding to the set overlap region, the resource region selected based on the received information from resource regions for transmission of uplink data channels,
- wherein the overlap region is set based on the self-interference cancellation capacity with a size configured in inverse proportion to the self-interference cancellation capacity.
A BS for mitigating self-interference in a full duplex radio (FDR) communication environment, the BS comprising:
- a transmitter configured to transmit information;
- a receiver configured to receive information;
- and
- a processor connected to the transmitter and the receiver and configured to:
- control the receiver to receive information from a user equipment (UE), the information related to self-interference cancellation capacity of the UE;
- set an overlap region from resource regions for transmission of a plurality of downlink control channels, the overlap region corresponding to a resource region in which an influence of self-interference caused by uplink communication of the UE must be removed;
- and
- control the transmitter to transmit information related to the set overlap region to one or more UEs connected to the BS in order to perform FDR communication,
- wherein the overlap region is set based on the self-interference cancellation capacity with a size configured in inverse proportion to the self-interference cancellation capacity.
A UE for mitigating self-interference in a full duplex radio (FDR) communication environment, the UE comprising:
- a transmitter configured to transmit information;
- a receiver configured to receive information;
- and
- a processor connected to the transmitter and the receiver and configured to:
- control the transmitter to transmit information to a base station (BS), the information related to self-interference cancellation capacity of the UE;
- control the receiver to receive information from the BS, the information related to a set overlap region corresponding to a resource region among resource regions for transmission of a plurality of downlink control channels in which an influence of self-interference caused by uplink communication to the BS must be removed;
- and
- mitigate the self-interference from a resource region corresponding to the set overlap region, the resource region selected based on the received information from among resource regions for transmission of uplink data channels,
- wherein the overlap region is set based on the self-interference cancellation capacity with a size configured in inverse proportion to the self-interference cancellation capacity.
