Abstract: During an uplink TDD slot, an UL UE transmits an UL signal that occupies a slot frequency range. Similarly, during a DL TDD slot, a DL UE receives a DL signal that occupies the slot frequency range. But during an SBFD slot, a UL UE transmits a UL signal that occupies only a first sub-band of the slot frequency range. Similarly, a DL UE receives a DL signal during an SBFD slot that occupies only a second sub-band of the slot frequency range. The second sub-band is distinct from the first sub-band. The DL UE may thus mitigate UE-to-UE interference during an SBFD slot by filtering the DL signal to substantially block the second sub-band from being received at the DL UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an energy per resource element (EPRE) value for a slot based at least in part on whether the slot is associated with a half-duplex configuration or a full-duplex configuration, wherein the EPRE value is a first value when the slot is associated with the half-duplex configuration and a second value when the slot is associated with the full-duplex configuration; and perform a communication in the slot in accordance with the EPRE value. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure are directed towards apparatus and techniques for wireless communication. An example apparatus generally includes: a first transmit chain; a first receive chain; a first coupler coupled to the first transmit chain; a second coupler coupled to the first receive chain; a first analog interference cancellation (AIC) circuit having an input coupled to the first coupler and an output coupled to the first receive chain; and a first routing device coupled between the first coupler and the input of the first AIC circuit, the first routing device being further coupled between the first coupler and a digital interference cancellation (DIC) circuit.

Abstract: A base station is disclosed that includes two separated antenna arrays. In a TDD mode of operation, both arrays are used for either transmit or receive. In a sub-band full-duplex mode of operation, one array is used to transmit downlink symbols while the remaining array is used to receive uplink symbols.
