Abstract
The present disclosure relates to an interference removal method according to application of a subband non-overlapping full duplex (SBFD) technology.
Claims17
A base station device comprising:
- a memory including an instruction;
- and
- a processor,
- wherein the processor is configured to, by executing the instruction:
- calculate uplink interference that is interference from a downlink to an uplink, arised from simultaneous use of the downlink and the uplink in frequency subbands;
- and
- differently determine a range of a guard band corre-sponding to a boundary frequency band between the downlink and the uplink according to a magnitude of the uplink inter-ference.
4 more elements
A terminal comprising:
- a memory including an instruction;
- and
- a processor,
- wherein the processor is configured to, by executing the instruction:
- in case that a downlink and an uplink are simultaneously used in frequency subbands, for calculation of uplink interference that is interference from the downlink to the uplink, measure a cross-link interference (CLI)-RSSI value;
- and
- transmit the CLI-RSSI value to a base station device so as to support the base station device to differently de-termine a range of a guard band corresponding to a boundary frequency band between the downlink and the uplink according to a magnitude of the uplink interference calculated based on the CLI-RSSI value, and
- wherein a resource in the guard band is excluded from resources for measurement and transmission of the CLI-RSSI value.
5 more elements
An interference removal method performed by a base station device, the method comprising:
- calculating uplink interference that is interference from a downlink to an uplink, arised from simultaneous use of the downlink and the uplink in frequency subbands;
- and
- differently determining a range of a guard band corre-sponding to a boundary frequency band between the downlink and the uplink according to a magnitude of the uplink inter-ference.
