Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station via the transceiver, an indication to apply an amplitude drooping based at least in part on an uplink band being adjacent to a downlink band in a full-duplex operation. The UE may transmit, to the base station via the transceiver, an uplink transmission in the uplink band based at least in part on the amplitude drooping. Numerous other aspects are described.
Claims30
An apparatus for wireless communication at a user equipment (UE), comprising:
- a memory;
- a transceiver;
- and
- one or more processors, coupled to the memory, configured to:
- receive, from a base station via the transceiver, an indication to apply amplitude drooping to change a signal power of a signal based at least in part on an uplink band being adjacent to a downlink band in a full-duplex operation, the amplitude drooping changing the signal power due to at least one of radio frequency filtering applied to the signal or a frequency response of a digital or analog conversion;
- and
- transmit, to the base station via the transceiver, an uplink transmission in the uplink band based at least in part on the amplitude drooping.
