Abstract: Apparatuses and methods for switching between SBFD and HD modes for different periodicities are described. An apparatus is configured to operate in a SBFD mode associated with a SBFD operation or a HD mode. SBFD operations are associated with SB sets and the HD mode is associated with time/frequency resource sets. The apparatus is configured to obtain first indications of a time/frequency location for each SB, or second indications of the time/frequency resources, and switch to operate in another of the SBFD or the HD mode based on the first or second indications. Another apparatus is configured to configure time/frequency locations for SBs of SBFD operations associated with SBFD modes and time/frequency resources of a HD mode, and transmit, for a UE, first indications of the time/frequency locations, or second indications of the time/frequency resources.

Abstract: The present disclosure provides for a configuration that enables an apparatus to determine beam pairs for full duplex communication based on a cross-link interference procedure. The apparatus determines a subset of receive beams based on a beam measurement process, where each receive beam is associated with a different antenna array panel. In some aspects, the apparatus performs a channel measurement process based on the subset of receive beams. The apparatus sweeps through transmitted sounding reference signals from a same transmit beam corresponding to each receive beam of an antenna array panel and receives the transmitted sounding reference signals incrementally through other receive beams associated with other antenna array panels. The apparatus measures a self-interference for at least one beam pair of the subset of receive beams based on a received sounding reference signal. The apparatus selects one or more beam pairs based on a self-interference measurement or a signal-to-interference-plus-noise ratio.

Abstract: Aspects are provided which allow a network entity to configure and a UE to transmit subband CSI reports in full duplex slots. Initially, the UE receives a CSI report configuration indicating a plurality of CSI subbands of at least one bandwidth part BWP. Subsequently, the UE receives a CSI-RS in a slot associated with a full duplex mode, the slot being further associated with a frequency band including a downlink subband and an uplink subband. Afterwards, the UE transmits a CSI report, where the CSI report includes first CSI associated with the CSI-RS for a first one of the CSI subbands overlapping in frequency with the downlink subband, and the CSI report lacks second CSI for a second one of the CSI subbands overlapping in frequency with the uplink subband.

Abstract: Aspects of the disclosure provide techniques for wireless communication using sub-band full duplex (SBFD). A network entity can inform a user equipment (UE) on the allocation of communication resources for SBFD operations using sub-bands. The network entity can indicate sub-band allocation in symbols/slots configured for SBFD operations using various techniques. A UE can receive a SBFD configuration of one or more time slots, each time slot including a plurality of symbols. The SBFD configuration indicates that one or more of the plurality of symbols are capable of an SBFD operation using a first sub-band for downlink (DL) communication and a second sub-band for uplink (UL) communication. The UE can communicate with the network entity in the one or more symbols configured for the SBFD operation using at least one of the first sub-band for DL communication or the second sub-band for UL communication.

Abstract: Aspects described herein relate to mitigating interference between network nodes operating in full duplex (FD). In some aspects, a victim network node can indicate, to an aggressor network node, a capability to cancel interference from the aggressor network node, receive one or more uplink signals from a device along with one or more downlink signals from the aggressor network node in a same time period, and cancel, based on the capability, the one or more downlink signals received from the aggressor network node from the one or more uplink signals received from the device. In other aspects, the victim network node can indicate certain uplink resources to the aggressor network node, which can avoid transmitting downlink communications over the indicated uplink resources.

Abstract: Aspects of the present disclosure provide techniques for techniques and apparatuses for mitigating self-interference (SI) at a wireless node engaging in full duplex (FD) communication. A method that may be performed by a network entity includes determining a trigger condition is satisfied for requesting an uplink (UL) signal from a user equipment (UE) for SI measurement, transmitting, to the UE, an indication to transmit the UL signal in one or more first symbols, wherein the one or more first symbols are prior to one or more second symbols for UL transmission by the UE, and wherein the one or more first symbols are scheduled for a downlink (DL) transmission by the network entity in a full duplex (FD) mode, measuring the UL signal, adjusting an automatic gain control (AGC) level based on the measurements, and using the adjusted AGC level to receive the UL transmission from the UE.

Abstract: A user equipment (UE) reports, to a base station, UE duplex communication characteristics. The UE then communicates with the base station in accordance with the reported characteristics. The characteristics can include duplex communication modes supported by the UE. The modes can include receiving and transmitting concurrently with the base station; communicating in a first direction with the base station and concurrently communicating in an opposite direction with a second base station; communicating with the i in a first direction concurrent with the base station communicating in an opposite direction with another UE; and communicating in half duplex (HD) with the base station in HD. The UE can receive, from the base station, a command to communicate in a reported mode. In such cases, communicating, by the UE with the base station, in accordance with the reported duplex communication characteristics includes communicating with the base station in the commanded mode.
