摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a cell-level cross link interference sounding reference signal (CLI-SRS) configuration, wherein the cell-level CLI-SRS configuration identifies CLI-SRS resources in one or more full-duplex slots for cross link interference measurements associated with Uu and sidelink communications. The UE may receive an indication to transmit a CLI-SRS, or to measure cross link interference, in a CLI-SRS resource of the CLI-SRS resources identified in the cell-level CLI-SRS configuration. The UE may transmit the CLI-SRS in the CLI-SRS resource or measuring cross-link interference in connection with a CLI-SRS transmission from another UE in the CLI-SRS resource based at least in part on the indication. Numerous other aspects are described.

摘要： In a wireless network, a base station may configure a victim user equipment (UE) experiencing interference with a periodic measurement resource using Layer 3 (L3) signaling, and the UE may report cross-link interference (CLI) measurements to the base station using L3 messages. However, using L3 signaling to configure interference measurement and reporting may result in an inflexible interference measurement configuration and a long latency to report CLI and/or self-interference feedback. Furthermore, although Layer 1 and/or Layer 2 (L1/L2) CLI reporting may be more suitable to track and adapt to dynamic changes in interference conditions, L1/L2 signaling increases control signaling and CLI management overhead at the base station. Accordingly, some aspects described herein relate to an adaptive L3 CLI measurement and reporting framework, where L3 messages may include one or more adaptive fields to support flexibility in configuring CLI measurement and/or CLI reporting parameters.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration of a plurality of bandwidth parts (BWPs) in a frequency band, wherein the configuration identifies a respective BWP-specific downlink (DL)-uplink (UL) pattern for each BWP of the plurality of BWPs, and wherein at least two of BWPs of the plurality of BWPs are configured with different BWP-specific DL-UL patterns and wherein each DL-UL pattern specifies which time intervals of a plurality of time intervals are dedicated to downlink and which time intervals of the plurality of time intervals are dedicated to uplink. The UE may communicate with the base station in one or more active BWPs of the plurality of BWPs using the respective BWP-specific DL-UL pattern for each of the one or more active BWPs. Numerous other aspects are described.

摘要： Techniques for supplementary sidelink resource configuration in full duplex mode may include a first user equipment (UE) transmitting to a base station an interference report indicating sidelink communication interference. The base station may select a resource pool according to the interference report, where the resource pool includes supplementary sidelink subchannels reserved for receiving sidelink communications and conditionally reserved for transmitting sidelink communications based on the interference report. The base station may transmit, to the first UE or a second UE causing the sidelink communication interference, configuration information indicating the resource pool. Based on the configuration information, the first UE and/or the second UE may perform sidelink communications (with each other or with other UEs) using the supplementary sidelink sub channels.

摘要： Aspects of the present disclosure include methods and devices for informing a base station of autonomously selected SL resources to allow the base station to adjust the DL transmission to mitigate the degradation of the reception of a DL transmission due to self-interference that overlaps with a SL transmission. A device may be configured to select resources for a SL transmission and to transmit, in an UL transmission to a base station, an indication of the resources selected for the SL transmission. A base station may be configured to receive, in an UL transmission, an indication of resources selected for a SL transmission from a UE, and to transmit, based on the indication of the resources selected for the SL transmission, at least one DL transmission that overlaps in time with the SL transmission.

摘要： The apparatus may be a UE configured to communicate, in a FD mode, with at least one base station via an unlicensed spectrum; determine to cancel at least one UL transmission corresponding to one or more UL resources, the one or more UL resources corresponding to a LBT procedure; and cancel, based on the determination, the at least one UL transmission corresponding to the one or more UL resources. The apparatus may be a base station configured to communicate, in a FD mode, with one or more UEs via an unlicensed spectrum; determine that a LBT procedure associated with DL scheduling will occur via a set of UL resources; and transmit, to the one or more UEs based on the determination, an indication of a cancelation of one or more UL transmissions during the set of UL resources.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a full-duplex user equipment (UE) may identify timing for performing an interference measurement based at least in part on a scheduled uplink transmission time. The full-duplex UE may perform, in a particular symbol and in accordance with the timing for performing the interference measurement, a self-interference measurement and a cross-link interference measurement. Numerous other aspects are provided.

摘要： A user equipment (UE) communicates with a base station operating in a sub-band frequency division duplexing (FDD) mode. The UE receives a downlink transmission in a usable bandwidth (BW) of an active downlink bandwidth part (BWP) in a sub-band full duplex (SBFD) slot, where the usable BW does not include frequency resources used for guard band and uplink transmission. The UE monitors for one or more control resource set (CORESET) configured by the base station within the active downlink BWP during monitoring occasions.

摘要： Certain aspects of the present disclosure provide techniques for time aligning full-duplex communications. A method that may be performed by a base station (BS) includes transmitting, to a first user equipment (UE): an indication of a first uplink timing advance (TA) determined based on a first propagation delay between the BS and the first UE, and an indication of a first cyclic prefix (CP) length determined based on the first uplink TA. In certain aspect, the method also includes transmitting, to the first UE, a first downlink communication comprising a downlink CP, during a first time window comprising a plurality of time periods.
