  • Such a UE at a cell edge may receive increased CLI and the network may not be able to reduce or mitigate some of the CLI due to some of the other UEs not being coordinated or scheduled by the network node or primary serving cell of the UE.
  • a network node may initiate a CLI measurement and reporting procedure.
  • Cross link interference (CLI) measurement is defined in NR Rel-16 for one UE (victim) to measure interference strength from signals transmitted in another UE’s (aggressor) UL resource to the serving network node.

  • the network node may not be able to directly control or adjust the actions of devices of other cells and may not be as effective in reducing CLI caused by devices of other cells.
  • CLI problems are further exacerbated because a UE is operating with two communication links (possibly in two different cells) , and the UE may receive CLI on each of its two communication links from devices in multiple cells.
  • one CLI resource is associated with one potential aggressor UE.
  • the network configures multiple CLI resources to a victim UE, one for each potential aggressor UE, and the victim UE measures the CLI of each CLI resource serially one at a time.
  • multiple TRP operations may include additional CLI resources to measure as compared to single TRP operations, such as for additional potential aggressor UEs, the duration to perform the CLI measurement procedures duration would increase significantly. The latency caused by this increase in duration may cause the CLI measured to be inaccurate as channel conditions may change in the interim during the measurement process, and the latency may cause the CLI to not be mitigated for an extended period of time.

  • a UE transmits CLI measurement capability information indicating a capability for simultaneous CLI measurements to a network.
  • the UE may receive CLI resource information for multiple CLI resources from the network responsive to the transmission of CLI measurement capability information, and the CLI resource information may be determined in accordance with the CLI measurement capability information.
  • the UE After receiving the CLI measurement information, the UE then measures CLI for one or more of CLI resources indicated by the CLI resource information in accordance with or as indicated by the CLI resource information and the CLI measurement capabilities of the UE indicated by the CLI measurement capability information. The UE may then report the measured CLI to the network, such as to one or more network nodes of the network.

  • the CLI measurement capability information may explicitly indicate a particular or more demanding CLI measurement capability, which implicitly indicates one or more other or less demanding CLI measurement capabilities.
  • the UE may explicitly indicate simultaneous CLI measurement capability for CLI sounding reference signal (SRS) reference signal receive power (RSRP, SRS-RSRP) in spatial division multiplexing (SDM) , which may implicitly indicate or be interpreted as support for other CLI measurement capabilities, such as for CLI received signal strength indicator (RSSI) in frequency division multiplexing (FDM) , time division multiplexing (TDM) , and SDM.

  • SDM spatial division multiplexing
  • RSSI CLI received signal strength indicator

For example, the UE may be able to simultaneously measure CLI RSSI and CLI RSRP for two overlapping CLI resources, such as CLI RSSI of an uplink data transmission and CLI RSRP of an uplink sounding transmission (e.g., SRS) . In some other aspects, the UE may not be capable of measuring two different CLI resources simultaneously. For example, the UE may not have a second TRP or a second TRP available to measure a second CLI resource. In some such aspects, the UE may select or be indicated a single CLI resource to measure or the UE may measure a total CLI of both CLI resources. Additionally, or alternatively, the UE may measure multiple instances of a same CLI resource serially in time with different filter settings to determine CLI for different TRPs only using one TRP at a time.

  • the network may define the relationship between an indicated CLI resource of the CLI resource information and which potential aggressor UE is scheduled to transmit during the CLI resource.
  • the UE builds or determines the association information.
  • the UE may identify, determine, or select the association in accordance with UE selection criteria or in accordance with CLI measurement. To illustrate, the UE may identify the association during performance of the CLI measurement by identifying the transmitting device.
  • a network may configure UE operation such that intra-CLI and inter-CLI can be measured.
  • the network may utilize a victim UE’s timing (e.g., timing advance) to schedule the CLI resources to measure, and optionally to synchronize timing between transmitting devices (potential aggressor UE) and receive devices (victim UE) .
  • timing e.g., timing advance
  • enhanced and more flexible CLI measurement operations may be signaled and supported.
  • simultaneous CLI measurement capabilities in different mTRP modes may signaled for enhanced configuration by the network. This enables a network to schedule enhanced CLI measurement operations for multiple TRP modes to address the additional devices which may be causing CLI. Accordingly, CLI may be determined quicker and more accurately which saves network resources and enables quicker mitigation and recovery from CLI.
  • explicit indications of particular CLI measurement capabilities may enable precise indication of CLI measurement capabilities of a UE for use by the network.
  • implicit indication of particular CLI measurement capabilities may enable a reduction in signaling overhead (e.g., a number of bits of the CLI measurement capability information used to communicate the CLI measurement capabilities of the UE) , which reduces signaling bandwidth and processing.
  • a UE measuring two CLI resources at the same time reduces latency in determining CLI and enable faster mitigation of CLI. For example, a device may determine CLI for two different devices simultaneously, which enables the device to determine which other device is contributing CLI to which communication link or links.
  • association information devices of the network may be able to specifically identify which device or devices are contributing to the CLI. This identification of devices enables more accurate CLI determination and mitigation. Additionally, by the flexible configurations described herein for network node or UE generation of the association information, the network may have enhanced configurability and flexibility and may offload some processing to UEs to save resources.
  • inter-CLI measurements may be possible in addition to intra-CLI measurements.
  • victim UE’s timing parameter the network may be able to more efficiently ensure that a timing difference between the victim UE and potential aggressor UEs is within one cyclic prefix, which may enable mTRP operations.
