  • Publication number: 20240056899
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may adjust signaling in a slot configured for subband full-duplex (SBFD) communications based on receiving scheduling information indicating a signal. In a first option, a corresponding subband may be extended to include the signal. If there are remaining frequency resources, the remaining reverse-direction subband may be used for corresponding communications. In a second option, the remaining frequency resources of the reverse-direction subband may be used for same-direction communications as the signal. In a third option, the signal may be canceled, or a portion of the signal that is outside the corresponding subband may be canceled. In a fourth option, the signal may be treated as an error. In some examples, the options may be configured based on a type of the signal, or based on a priority level of the signal.

  • Publication number: 20240056153
    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.

  • Publication number: 20240057050
    Abstract: Methods, systems, and devices for wireless communications are described. Example wireless communications systems may implement control signaling configuring a user equipment (UE) to communicate in a subband full-duplex (SBFD) mode. An SBFD mode may include a non-contiguous bandwidth part (BWP), and control signaling may indicate the resource blocks (RB)s included in the non-contiguous BWP. In some cases, the non-contiguous BWP may be for communications between the UE and the network in one communications direction (e.g., uplink or downlink), and another BWP may be configured for communications between the UE and the network in the other communications direction. The non-contiguous BWP may include two subbands, and the other BWP may be non-overlapping with (e.g., positioned between) the two subbands in the frequency domain. The network may configure a BWP time domain switching pattern (e.g., switching between SBFD and half-duplex modes according to a BWP time domain switching pattern).

  • Publication number: 20240056854
    Abstract: Systems and techniques are provided for performing wireless communications at a user equipment (UE). For example, a process can include transmitting, from a UE based on a cross-link interference (CLI) cancellation capability of a receiver of the UE, a CLI cancellation capability indication. The process can include receiving, at the UE, a communications signal. In some implementations, the UE received the communications signal from a network entity. In some cases, receiving the communications signal from the network entity at least partially coincides with a transmission of an additional communications signal by an additional UE, wherein the additional UE is different from the UE.

  • Publication number: 20240048349
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a sub-band full-duplex (SBFD) configuration of a cell serving the UE. The SBFD configuration may indicate a first set of resources for downlink communications and a second set of resources for uplink communications. The first set of resources and the second set of resources may include non-overlapping frequency resources in a same time interval. The UE may receive a control message that indicates a pre-emption of the first set of resources or a cancellation of the second set of resources. Accordingly, the UE may determine that downlink transmissions in at least a portion of the first set of resources are pre-empted or that uplink transmissions in at least a portion of the second set of resources are cancelled based on the control message and the SBFD configuration of the cell.

    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.

  • Publication number: 20240040388
    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.

  • Publication number: 20240039679
    Abstract: A user equipment (UE) may use a resource configuration to determine whether to transmit or receive on a particular sub-band during a given communication period (e.g., a time slot or a symbol duration). In some examples, a network entity provides a bit map to a UE where the bit map indicates how sub-bands for a given communication period are allocated for full-duplex transmissions. The UE may then determine, based on the bit map, whether to transmit or receive on a particular sub-band. In some examples, a network entity provides a resource configuration to a UE where the resource configuration indicates how half-duplex transmissions and full-duplex transmissions are configured over a period of time. In this case, the UE may be configured by a defined rule to determine, based on the resource configuration, whether to transmit or receive on a particular sub-band.
