Classification: CPC H | IPC H

Claim 8:
9. A downlink user equipment, comprising:
a processor;
a modem; and
a transceiver, wherein the processor is configured to control the transceiver to:
receive a radio frequency (RF) signal that includes a downlink (DL) signal occupying a first sub-band of a slot frequency band for a sub-band-full-duplex (SBFD) slot and that further includes an uplink (UL) signal from an UL user equipment, the UL signal occupying a second sub-band of the slot frequency band, wherein the processor is further configured to control the downlink user equipment to not transmit an UL signal in the SFBD slot, and wherein the first sub-band comprises a lower sub-band and an upper sub-band of the slot frequency band and the second sub-band comprises a central sub-band of the slot frequency band, the lower sub-band being separated in frequency from the upper sub-band by the central sub-band;
down convert the RF signal in frequency to form a baseband signal that includes a down converted version of the DL signal and a down converted version of the UL signal;
high-pass filter the baseband signal to pass the down converted version of the DL signal to the modem and to substantially block the down converted version of the UL signal from being passed to the modem;
detect that the UL signal is causing interference at the downlink user equipment; and
transmit a message from the downlink user equipment to a base station to request that the base station transmit a command to the UL user equipment to change a scheduling of time and/or frequency allocations for the UL user equipment to reduce the interference.
