Description

Technical Field

Background Technology

[0002] The communications field is constantly evolving to provide efficient and reliable solutions for utilizing wireless communication networks. To meet the increasing demand for wireless data services since the deployment of fourth-generation (4G) communication systems, efforts have been made to develop an improved new radio (NR) communication system.

In TDD, time-domain resources are split between downlink and uplink. 3GPP has agreed to study the evolution of duplex operations in NR, which could allow simultaneous downlink (DL) and uplink (UL) transmissions on different physical resource blocks (PRBs) within an unpaired broadband NR cell (which may be called SBFD).

[0041] Some implementations may involve duplex evolution, including Subband Non-overlapping Full-Duplex (SBFD). 3GPP 5G NR currently supports two duplex modes: FDD for paired frequency bands and TDD for unpaired frequency bands. In TDD, time-domain resources are split between the downlink and uplink. Allocating limited durations for the uplink in TDD results in reduced coverage, increased latency, and decreased capacity.

[0042] Inspired by this, 3GPP has agreed to launch the Rel-18 research project on the evolution of duplex operation in NR to address the aforementioned challenges. One of the goals of this research project is to allow simultaneous DL and UL transmissions on different Physical Resource Blocks (PRBs) / subbands within unpaired broadband NR cells. This can be referred to as Subband Non-overlapping Full-Duplex (SBFD). In the context of this disclosure, the duplexing scheme for SBFD can also be referred to as Cross-Division Duplex (xDD) or Flexible Duplex (FDU).

[0043] Both DL and UL transmissions have two timeslot types: SBFD timeslots and non-SBFD timeslots. Several SBFD operation modes have been investigated, including whether the SBFD-aware UE knows the time and frequency location of the subband used for SBFD operation. However, it was agreed at the 3GPP RAN1#110 meeting that operation modes with at least the SBFD-aware UE knowing the time and frequency location of the SBFD operation subband are preferred. This means that the (SBFD-aware) UE should know the SBFD timeslot in one way or another.

[0044] The SBFD scheme can introduce at least one type of cross-link interference (CLI), which can be called co-channel sub-band CLI. This interference can be divided into: (1) gNB self-interference; (2) intra-cell UE-UE co-channel sub-band CLI; (3) inter-cell UE-UE co-channel sub-band CLI; and (4) gNB-gNB co-channel sub-band CLI. In addition to these new CLI types (1)-(4), if the frequency domain divisions in adjacent cells are different, the system may also be affected by co-channel sub-band CLI (i.e., CLI from transmissions on overlapping frequency resources): (5) gNB-gNB inter-cell co-channel sub-band CLI; and (6) UE-UE inter-cell co-channel sub-band CLI.

[0045] In Rel-16, regarding inter-UE CLI measurements, only broadband CLI measurements are reported. In RAN1#110bis-e, it has been agreed to study the impact / potential enhancements of UE-to-UE CLI Received Signal Strength Indication (CLI-RSSI) measurements / reporting that take into account discontinuous measurement resources in the frequency range. The following text boxes describe some non-restrictive objectives of the R18 study related to inter-UE subband CLI measurements.

[0046] Due to the specific structure of frequency domain allocation in SBFD time slots, such as DUD frequency resource partitioning (i.e., uplink sub-bands between two downlink sub-bands), the available DL resources in an SBFD time slot may be discontinuous, and multiple UL sub-bands, DL sub-bands, and guard bands may exist within an SBFD time slot. Traditional CLI-RSSI measurement methods based on broadband measurement / reporting or based on discontinuous CLI-RSSI measurement resources (the protocol in RAN1#110bis-e) cannot quickly and completely reflect the CLI-RSSI status of each sub-band / spectrum block.

[0047] According to the latest #112 bis-e protocol, CLI-RSSI can be measured both inside and outside the DL subband. Furthermore, in the future, flexible SBFD and full-duplex modes may require full-bandwidth measurement and reporting. Therefore, a solution is needed to directly measure and report CLI-RSSI across all subbands, which will benefit network efficiency and performance.

[0048] This disclosure provides an example embodiment of a solution for measuring and reporting CLI in an SBFD scheme. Specifically, a method for utilizing the continuous allocation of measurement resources covering at least two different types of subbands can be provided. The terminal device can utilize the allocated measurement resources to measure CLI levels (e.g., RSSI) in different subbands within the same time slot and report CLI measurements in various flexible ways to cover a wide range of use cases. The principles and embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0049] First refer to Figure 1A The illustration depicts an example communication system 100 in which embodiments of the present disclosure can be implemented. System 100 includes a terminal device 110 and a network device 120. Terminal device 110 can connect and communicate with network device 120 in either the UL or DL, provided that terminal device 110 is located within a corresponding cell of network device 120. In the communication system, UL refers to the link in the direction from terminal device 110 to network device 120, and DL refers to the link in the direction from network device 120 to terminal device 110. Network device 120 can send scheduling information to terminal device 110 for scheduling uplink transmissions, and terminal device 110 can send multiple repetitions of uplink transmissions to network device 120.

[0050] Communication in communication system 100 can be implemented according to any suitable communication protocol(s), including but not limited to cellular communication protocols of the first generation (1G), second generation (2G), third generation (3G), fourth generation (4G) and fifth generation (5G), wireless local area network communication protocols such as IEEE 802.11, and / or any other protocols currently known or to be developed in the future. Furthermore, communication can utilize any suitable wireless communication technology, including but not limited to: Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Frequency Division Duplex (FDD), Time Division Duplex (TDD), Multiple Input Multiple Output (MIMO), Orthogonal Frequency Division Multiplexing (OFDM), Discrete Fourier Transform Extended OFDM (DFT-s-OFDM), and / or any other technologies currently known or to be developed in the future.

[0051] It should be understood that Figure 1AThe number, connection relationships, and types of the devices shown (i.e., terminal device 110 and network device 120) are for illustrative purposes only and do not represent any limitation. For example, communication system 100 may include any suitable number of devices suitable for implementing embodiments of this disclosure. For example, although Figure 1A Terminal device 110 is described as a mobile phone, but terminal device 110 can be any type of user equipment.

[0052] Based on the above discussion, the following will describe some content in further detail with reference to the accompanying drawings. Figure 1B The diagram illustrates the frequency and time resource allocation using SBFD compared to FDD and TDD. Figure 1C The diagram illustrates SBFD and non-SBFD time slots. During SBFD time slots, both non-overlapping DL subbands and (multiple) UL subbands are present, and during non-SBFD time slots, the entire bandwidth is used for either DL or UL (i.e., conventional / full DL / UL time slots). It should be noted that the reference... Figure 1C SBFD and non-SBFD time slots are illustrated; however, this disclosure also applies to SBFD microslots and non-SBCD microslots, or SBFD symbols and non-SBFD symbols, or other time units not listed herein. Although Figure 1C Although not shown, a guard band may exist between the DL subband and UL subband in an SBFD time slot. It should be understood that although the SBFD time slot is illustrated as having DUD frequency resource allocation, this is not intended to limit the exemplary embodiment.

[0053] Figure 1D and Figure 1E The diagram illustrates the types of co-channel interference in SBFD deployment. Refer to the above content. Figure 1D The diagram illustrates gNB self-interference (1), intra-cell UE-UE co-channel subband CLI (2), inter-cell UE-UE co-channel subband CLI (3), and gNB-gNB co-channel subband CLI (4). Figure 1E The diagram illustrates CLI (5) within the same channel subband between gNB and gNB and CLI (6) within the same channel subband between UE and UE.

[0054] Figure 2 An example signaling diagram of an example process 200 according to some embodiments of the present disclosure is illustrated. For discussion purposes, reference will be made to... Figure 1A Description Example 200, process 200 may involve, for example Figure 1A The terminal device 110 and network device 120 are shown. It should be understood that, although in Figure 1A The process 200 is described in the communication system 100, but the process can also be applied to other communication scenarios.

[0055] like Figure 2As shown, network device 120 sends a resource indication 212 210 to terminal device 110 for at least one resource for at least one CLI measurement. The at least one resource overlaps with multiple subbands in an SBFD time unit, and the multiple subbands have at least two subband types. Terminal device 110 receives the resource indication 212 214. In other words, the indicated resource can be used for CLI measurement. In some embodiments, terminal device 110 will not perform a transmission on the indicated resource. For example, the indicated resource may be implemented as a ZP-CSI-RS resource or a CSI-IM resource. In some embodiments, the time unit may be a time slot, a micro-time slot, a symbol, or any other time unit not listed herein.

[0056] Network device 120 sends configuration information 218 (216) to terminal device 110. Configuration information 218 indicates at least one subband among a plurality of subbands, for which at least one CLI measurement will be reported. Terminal device 110 receives configuration information 218 (220) and performs at least one CLI measurement (222) based on resource indication (212) and configuration information 218. Terminal device 110 sends at least one measurement report (226) (224) to network device 120 for reporting at least one CLI measurement. Network device 120 receives at least one measurement report (226) (228). In this way, the measurement report can directly reflect the CLI level of the subband in the SBFD scheme, and is not limited to the DL subband, which improves communication efficiency and performance.

[0057] In some embodiments, at least two subband types may include at least two of the following: DL subband type, guard band type, or UL subband type. For example, a resource for at least one CLI measurement may overlap with a DL subband and a guard band within an SBFD time unit. In another example, a resource for at least one CLI measurement may overlap with a DL subband, a guard band, and a UL subband within an SBFD time unit. In some embodiments, at least one resource may be continuous in the frequency domain. For example, at least one resource may overlap with multiple continuous subbands within an SBFD time unit. In some embodiments, at least one resource may repeat periodically in the time domain. For example, at least one resource may repeat periodically according to a pattern of the SBFD time unit.

[0058] In some embodiments, at least one CLI measurement can be performed on at least one sub-band in the SBFD time unit. In other words, the sub-band(s) to be measured can be the same as the sub-band(s) to be reported. Terminal device 110 can perform the CLI measurements(s) on the sub-band(s) to be reported. This can be predefined, specified, implicitly indicated, or explicitly indicated. In some embodiments, configuration information can also indicate that at least one sub-band will be measured.

[0059] In some embodiments, network device 120 may send measurement configuration information to terminal device 110 indicating the subband(s) to be measured. In some examples, the subband(s) to be measured may be the same as the subband(s) to be reported. In another example, the subband(s) to be measured may be different from the subband(s) to be reported.

[0060] In some embodiments, at least one CLI measurement can be performed on multiple subbands within an SBFD time unit, and at least one measurement report can be associated with at least one subband. In other words, terminal device 110 can perform multiple CLI measurements on multiple subbands that overlap with the indicated resources for CLI measurements, and report multiple CLI measurements associated with the multiple subbands to be reported.

[0061] In some embodiments, network device 120 may determine at least one of at least one resource and at least one subband based on the determination that both the network device and the terminal device support SBFD mode. For example, embodiments of this disclosure can be applied to communication systems where both the terminal device and the network device support SBFD mode.

[0062] In some embodiments, configuration information may include a bitmap indicating at least one subband. In other words, a bitmap can be used to indicate the subband(s) to be reported. In some embodiments, bits in the bitmap may correspond to subbands among multiple subbands in an SBFD time unit. In other words, corresponding bits in the bitmap can be used to indicate whether or not to report each subband in the SBFD time unit. In some examples, the number of bits in the bitmap may be at least equal to or greater than the number of subbands in the SBFD time unit. In some embodiments, bits in the bitmap may correspond to at least two adjacent subbands or one subband among multiple subbands in the SBFD time unit.

[0063] In some embodiments, the bits in the bitmap may correspond to one of the following: DL subband type, guard band type, or UL subband type. In other words, the corresponding bits in the bitmap can be used to indicate whether or not to report each type of subband in the SBFD time unit. In some examples, the number of bits in the bitmap may be at least equal to or greater than the number of subband types in the SBFD time unit.

[0064] In some embodiments, the configuration information includes an indication that at least one subband includes at least one DL subband among a plurality of subbands. Alternatively, the configuration information includes an indication that at least one subband includes at least one guard band among a plurality of subbands. Alternatively, the configuration information includes an indication that at least one subband includes at least one UL subband among a plurality of subbands. Alternatively, the configuration information includes an indication that at least one subband includes a plurality of subbands. In other words, network device 120 can configure terminal device 110 to report only the DL subband(s), only the guard band(s), only the UL subband(s), or all subbands in the SBFD time unit.

[0065] In some embodiments, configuration information may be transmitted via Radio Resource Control (RRC) signaling. Alternatively or additionally, configuration information may be transmitted via Media Access Control (MAC) control element (CE). Alternatively or additionally, configuration information may be transmitted via Downlink Control Information (DCI).

[0066] In some embodiments, at least one measurement report may include a combined report of at least one measured CLI level of at least one CLI measurement corresponding to at least one subband. In some embodiments, the combined report may include the maximum measured CLI level of at least one CLI measurement. Alternatively or additionally, the combined report may include the minimum measured CLI level of at least one CLI measurement. Alternatively or additionally, the combined report may include the average measured CLI level of at least one CLI measurement.

[0067] In some embodiments, at least one measurement report may indicate at least one measured CLI level of at least one CLI measurement corresponding to at least one subband type of at least one subband. In other words, CLI levels corresponding to the same subband type may be reported in combination.

[0068] In some embodiments, at least one measurement report may indicate the CLI level of at least one CLI measurement corresponding to at least one sub-band. In other words, the CLI level corresponding to each sub-band may be reported. In some embodiments, at least one sub-band may include a first sub-band and a second sub-band. The first measurement report corresponding to the first sub-band in at least one measurement report may include an absolute value, and the second measurement report corresponding to the second sub-band in at least one measurement report may include an offset value relative to the absolute value. The measurement report may include an absolute value indicating the CLI level corresponding to one sub-band and offset values ​​(multiple) indicating the CLI level (multiple) corresponding to the absolute value (multiple) corresponding to the absolute value (multiple) corresponding to the absolute value (multiple) corresponding to the absolute value (multiple) corresponding to the absolute value (multiple) corresponding to the absolute value (multiple) corresponding to the absolute value (multiple) of the CLI level (multiple) corresponding to the absolute value (multiple) of the sub-band (multiple) corresponding to the absolute value (multiple) of the sub-band (multiple) of the same sub-band (multiple) type (multiple)).

[0069] In some embodiments, terminal device 110 may perform CLI measurements on non-SBFD time units. At least one measurement report may also indicate the measured CLI level of the CLI measurement. The measured CLI level may be indicated by an absolute value, and at least one measured CLI level may be indicated by at least one offset value relative to the absolute value. The measurement report may include an absolute value indicating the CLI level corresponding to a non-SBFD time unit and an offset value relative to the absolute value indicating the CLI level corresponding to the sub-band(s) in the SBFD time unit(s).

[0070] In some embodiments, at least one subband may include a first type of subband and a second type of subband. The first reporting range corresponding to the first type of subband and the second reporting range corresponding to the second type of subband may be different. By providing different reporting ranges for CL measurements on different types of SBFD subbands, resource consumption and transmission efficiency for measurement reporting can be reduced.

[0071] Figure 3A The illustration shows a schematic diagram of a CLI measurement and reporting process 300A according to some embodiments of the present disclosure. Process 300A may be... Figure 2 A more specific example of process 200. Terminal device 110 may be abbreviated as UE, and network device 120 may be abbreviated as gNB.

[0072] like Figure 3AAs shown, at block 310, the UE can receive CLI-RSSI resource configuration from the gNB. In some embodiments, the CLI-RSSI resource configuration may indicate measurement resources (e.g., Zero Power Channel State Information Reference Signal (ZP-CSI-RS) resources, or Channel State Information Interference Measurement (CSI-IM) resources) across the entire bandwidth. Alternatively, the measurement resources may cover a portion of the entire bandwidth. (Refer to...) Figure 3B A sample implementation of CLI-RSSI resource configuration in SBFD time slots is described in detail.

[0073] In some embodiments, the gNB may send a frequency band configuration to the UE prior to the transmission of CLI-RSSI resource configuration. For example, the frequency band configuration may indicate one or more of the following: frequency band, a first number of time units for uplink and downlink transmission, a first position of a first number of time units in a radio frame, a second number of time units for uplink transmission, a second position of a second number of time units in a radio frame, a third number of time units for downlink transmission, a third position of a third number of time units in a radio frame, or a resource allocation type. In some examples, a time unit may be any of the following: a time slot, a micro-time slot, or a symbol.

[0074] In some examples, the frequency band configuration may indicate the frequency band. Alternatively or additionally, the frequency band configuration may indicate the number of time slots / micro-time slots / symbols during which the frequency band is divided into multiple sub-bands, and at least one sub-band is used for DL ​​transmission and at least another sub-band is used for UL transmission, i.e., the number of SBFD time slots / micro-time slots / symbols, and the location of that number of SBFD time slots / micro-time slots / symbols in the radio frame. Alternatively or additionally, the frequency band configuration may indicate the number of time slots / micro-time slots / symbols used for DL ​​or UL transmission throughout the entire frequency band, i.e., the number of non-SBFD time slots / micro-time slots / symbols, and the location of that number of SBFD time slots / micro-time slots / symbols in the radio frame.

[0075] Based on the frequency band configuration, the UE can know the SBFD deployment. The gNB can then send CLI-RSSI resource configuration to the UE. Figure 3B The illustration shows a schematic diagram of resource configuration 300B in an SBFD time slot according to some embodiments of the present disclosure. It should be noted that the resource configuration in an SBFD time slot with DUD frequency resource allocation is for illustrative purposes only and does not represent any limitation. Other resource configurations are also possible. Other SBFD time units are also possible, such as SBFD microslots or SBFD symbols. Furthermore, other frequency resource allocations in SBFD time units are also possible.

[0076] like Figure 3BAs shown, during one or more SBFD slots 350, there are non-overlapping DL subbands 320-1 and 320-2 and a UL subband 330. A guard band 340-1 exists between DL subband 320-1 and UL subband 330, and a guard band 340-2 exists between DL subband 320-2 and UL subband 330. Resource configuration can indicate ZP-CSI-RS / CSI-IM resources 360 in one or more SBFD slots 350. In some embodiments, the ZP-CSI-RS / CSI-IM resources 360 may be continuous in the frequency domain.

[0077] In some embodiments, the ZP-CSI-RS / CSI-IM resource may overlap with at least two of the following: multiple DL subbands in the SBFD time slot / microtime slot / symbol; multiple guard bands in the SBFD time slot / microtime slot / symbol; or multiple UL subbands in the SBFD time slot / microtime slot / symbol. Figure 3B In the example, ZP-CSI-RS / CSI-IM resource 360 ​​has DL subbands 320-1, 320-2, guard bands 340-1, 340-2, and UL subband 330. In some embodiments, ZP-CSI-RS / CSI-IM resource 360 ​​may periodically repeat according to a pattern of one or more SBFD slots 350. Based on resource configuration 300B, the UE will not perform transmissions on the indicated ZP-CSI-RS / CSI-IM resource 360.

[0078] The following text boxes show example illustrations of information elements for CLI-RSSI resource configuration. ZP-CSI-RS resources are configured with full bandwidth.

[0079] Back Figure 3A At box 312, the UE can receive CLI-RSSI reporting configuration from the gNB. The CLI-RSSI reporting configuration can indicate to the UE which subband(s) need to be measured and reported. The subband(s) indicated to be measured and reported can include at least one of the following: multiple DL subbands in SBFD slots / microslots / symbols, multiple guard bands in SBFD slots / microslots / symbols, or multiple UL subbands in SBFD slots / microslots / symbols. In some embodiments, the CLI-RSSI reporting configuration can be signaled to the UE using RRC signaling, DCI, or MAC CE messages.

[0080] In other words, the gNB can instruct the UE which subband(s) it needs to measure and report. For example, the gNB can configure the UE to perform CLI measurements (e.g., CLI-RSSI measurements) on a configured ZP-CSI-RS / CSI-IM resource based on whether the corresponding resource overlaps with (multiple) DL subbands in the SBFD slot / microslot / symbol. Alternatively or additionally, the gNB can configure the UE to perform CLI measurements on a configured ZP-CSI-RS / CSI-IM resource based on whether the corresponding resource overlaps with (multiple) guard bands in the SBFD slot / microslot / symbol. Alternatively or additionally, the gNB can configure the UE to perform CLI measurements on a configured ZP-CSI-RS / CSI-IM resource based on whether the corresponding resource overlaps with (multiple) UL subbands in the SBFD slot / microslot / symbol. The gNB can also configure the UE to report the performed measurements individually or jointly.

[0081] In some embodiments, the sub-band(s) indicated to be measured and the sub-band(s) indicated to be reported may not be exactly the same. For example, the sub-band(s) indicated to be reported may be a subset of the sub-band(s) indicated to be measured.

[0082] At box 314, the UE can determine whether the ZP-CSI-RS / CSI-IM resource is in the subband(s) to be measured and reported. If not, the UE can wait for a subsequent ZP-CSI-RS / CSI-IM resource. If so, procedure 300A can proceed to box 316. At box 316, the UE can measure and report the CLI-RSSI of the corresponding subband(s). For example, the UE can perform CLI measurements on ZP-CSI-RS / CSI-IM resources configured to overlap with the subband(s) indicated to be measured. Based on the network configuration signaled in box 312, and depending on whether the measurement is performed for resources overlapping with the subband(s) indicated to be reported, the UE can report the measurements jointly or individually.

[0083] For example, the gNB can configure periodic ZP-CSI-RS / CSI-IM resources for the UE and instruct the UE to perform CLI measurements on (multiple) DL subbands in the SBFD time slot. If the first ZP-CSI-RS / CSI-IM resource does not overlap with a DL subband in the SBFD time slot, the UE will not perform CLI measurements in the first ZP-CSI-RS / CSI-IM resource. If the second ZP-CSI-RS / CSI-IM resource overlaps with (multiple) DL subbands in the SBFD time slot, the UE can perform CLI measurements in the second ZP-CSI-RS / CSI-IM resource on the (multiple) overlapping DL subbands. For example, in Figure 3BIn the example shown, the UE can perform CLI measurements in ZP-CSI-RS / CSI-IM resources 360 on DL subbands 320-1 and 320-2 and report the CLI measurements to the gNB.

[0084] Alternatively or additionally, CLI-RSSI reporting configuration can designate (multiple) DL-only bands in non-SBFD time slots / micro-time slots / symbols for measurement and reporting. For example, when ZP-CSI-RS / CSI-IM resources overlap with (multiple) DL-only bands, the UE can perform CLI measurements in the ZP-CSI-RS / CSI-IM resources.

[0085] In some embodiments, the CLI-RSSI reporting configuration may include a bitmap to indicate which subband(s) ...)(s)

[0086] In some embodiments, in the case of DUD frequency resource allocation in SBFD time slots with guard bands(multiple) between DL subbands and UL subbands (e.g., Figure 3B One or more SBFD slots (350) in the bitmap can be 5 bits. In the example implementation, the first MSB or LSB of the 5-bit bitmap can correspond to the lower DL subband, the second MSB or LSB can correspond to the guard band between the lower DL subband and the UL subband, the third MSB or LSB can correspond to the UL subband, and so on.

[0087] For example, the first LSB of a 5-bit bitmap can correspond to Figure 3B The lower DL subband 320-2, the second LSB can correspond to the guard band 340-2 between the lower DL subband 320-2 and the UL subband 330, the third LSB can correspond to the UL subband 330, the fourth LSB can correspond to the guard band 340-1 between the DL subband 320-1 and the UL subband 330, and the fifth LSB of the 5-bit bitmap can correspond to the higher DL subband 320-1.

[0088] In the example implementation, if the CLI-RSSI reporting configuration includes a bitmap with a value of 01010, the UE can measure and report only the guard band(s) in the SBFD slot / micro-slot / symbol (e.g., Figure 3B ZP-CSI-RS / CSI-IM resources in the protection bands 340-1 and 340-2.

[0089] In the example implementation, if the bitmap is 01110, the UE can jointly measure and report (multiple) guard bands and UL subbands in SBFD timeslots / micro-timeslots / symbols (e.g., Figure 3B ZP-CSI-RS / CSI-IM (protection bands 340-1, 340-2 and UL sub-band 330 in ZP-CSI-RS / CSI-IM resource 360). For example, the UE can perform CLI measurements on protection bands 340-1, 340-2 and UL sub-band 330 in ZP-CSI-RS / CSI-IM resource 360 ​​and report combined reports of protection bands 340-1, 340-2 and UL sub-band 330 to the gNB, such as average / minimum / maximum CLI levels.

[0090] In the example implementation, if the gNB wants to configure the UE to separately measure and report ZP-CSI-RS / CSI-IM in the guard band and UL subband, the gNB can configure two CLI-RSSI reporting configurations for the UE. For example, one CLI-RSSI reporting configuration has bitmap 01010, and another CLI-RSSI reporting configuration has bitmap 00100. Based on the CLI-RSSI reporting configuration with bitmap 01010, the UE can measure and report ZP-CSI-RS / CSI-IM resources in the guard bands 340-1 and 340-2. Based on the CLI-RSSI reporting configuration with bitmap 00100, the UE can measure and report ZP-CSI-RS / CSI-IM resources in the UL subband 330. In this way, the gNB can acquire the CLI levels on the guard band and the CLI levels on the UL subband.

[0091] Alternatively, a CLI-RSSI report configuration may include multiple bitmaps. The UE can send multiple measurement reports corresponding to the multiple bitmaps to the gNB based on the CLI-RSSI report configuration.

[0092] In the example implementation, the DUD frequency resource allocation in the SBFD time slot with guard bands (multiple) between the DL subband and the UL subband (e.g., Figure 3B One or more SBFD slots (350) in the bitmap can be 3 bits. In the example implementation, the first MSB or LSB of the 3-bit bitmap can correspond to the lower DL subband, the second MSB or LSB can correspond to the UL subband and two guard bands, and the third MSB or LSB can correspond to the higher DL subband.

[0093] For example, the first LSB of a 3-bit bitmap can correspond to Figure 3B The lower DL subband 320-2, the second LSB can correspond to the UL subband 330 and the guard bands 340-1 and 340-2, and the third LSB of the 3-bit bitmap can correspond to the higher DL subband 320-1.

[0094] In the example implementation, the DUD frequency resource allocation in the SBFD time slot with guard bands (multiple) between the DL subband and the UL subband (e.g., Figure 3B One or more SBFD slots (350) in the bitmap can be 3 bits. In the example implementation, the first MSB or LSB of the 3-bit bitmap can correspond to the lower DL subband and the lower guard band, the second MSB or LSB can correspond to the UL subband, and the third MSB or LSB can correspond to the higher DL subband and the higher guard band.

[0095] For example, the first LSB of a 3-bit bitmap can correspond to Figure 3B The lower DL subband 320-2 and lower guard band 340-2 in the diagram, the second LSB can correspond to the UL subband 330, and the third LSB of the 3-bit diagram can correspond to the higher DL subband 320-1 and higher guard band 340-1.

[0096] The following text box shows an example illustration of the information elements of a 5-bit bitmap in the CLI-RSSI report configuration.

[0097] Regarding `reportFreqConfiguration`, `widebandCLI` indicates that multiple subbands are reported in a combined report. In other words, if CLI measurements are performed on multiple subbands, the combined (e.g., average) CLI levels on the multiple subbands are reported. `SubbandCLI` indicates that each subband has an independent result in a single report. In other words, if CLI measurements are performed on multiple subbands, the CLI levels on each of the multiple subbands are reported.

[0098] The Compact1 indicator, when the RSSI-FormatIndicator is in Subband CLI mode, reports a combination of measurements on (multiple) subbands of the same type. In other words, if CLI measurements are performed on multiple DL subbands, a combined (e.g., averaged) CLI level is reported across the multiple subbands.

[0099] The Compact2 indicator states that for multiple subbands of the same type, when the RSSI-FormatIndicator is in SubbandCLI mode, one subband is reported with a normal value (e.g., the absolute value of the CLI level), while the other subbands are reported with multiple offset values ​​relative to the normal value.

[0100] The Compact3 indicator states that, when the RSSI-FormatIndicator is in SubbandCLI mode, for all (multiple) subbands, only one subband is reported with a normal value (e.g., the absolute value of the CLI level), while the other (multiple) subbands are reported with (multiple) offset values ​​relative to the normal value.

[0101] The Compact4 indicator states that when the RSSI-FormatIndicator is in SubbandCLI mode, all (multiple) subbands are reported with (multiple) offset values ​​(relative to the normal values ​​measured only on the DL slot).

[0102] In some embodiments, the CLI levels for different subband types can be different. The RSSI reporting ranges for different subband types can be defined differently. For example, the 7-bit range of the CLI level on the DL subband can be defined as -60dB to -124dB. Therefore, a 7-bit value of 0000000 on the DL subband indicates a CLI level of -60dB with a step size of 0.5dB. The 7-bit range of the CLI level on the UL subband can be defined as -65dB to -129dB. Therefore, a 7-bit value of 0000000 on the UL subband indicates a CLI level of -65dB with a step size of 0.5dB. The 7-bit range of the CLI level on the guard band can be defined as -75dB to -139dB. Therefore, a 7-bit value of 0000000 on the guard band indicates a CLI level of -75dB with a step size of 0.5dB.

[0103] In some embodiments, the UE can always measure and report ZP-CSI-RS / CSI-IM resources individually in the multiple DL subbands, multiple UL subbands, and multiple guard bands. For example, the gNB can be configured to determine whether the UE should measure / report only the multiple DL subbands, only the multiple UL subbands, only the multiple guard bands, or all subbands in the SBFD slots / micro-slots / symbols. This can be done, for example, using a 2-bit indicator, where 00 corresponds to only the multiple guard bands, 10 corresponds to only the multiple DL subbands, 01 corresponds to only the multiple UL subbands, and 11 corresponds to all subbands.

[0104] In some embodiments, in the latter case (i.e., 2-bit indication 11), the UE can report three measurement reports, which is similar to the 5-bit bitmap embodiment, wherein three CLI-RSSI report configurations are provided to the UE, one CLI-RSSI report configuration having bitmap 10001, one CLI-RSSI report configuration having bitmap 01010, and one CLI-RSSI report configuration having bitmap 00100.

[0105] In some embodiments, in the latter case (i.e., 2-bit indication 11), the UE can combine measurement reports from all subbands into a full-band RSSI report. For example, the UE can transmit average / minimum / maximum CLI levels on all subbands.

[0106] The following text box shows an example illustration of the information element for the 2-digit indication used in CLI-RSSI report configuration.

[0107] Figure 4 The illustration shows a schematic diagram illustrating a method 400 implemented at a terminal device according to some other embodiments of the present disclosure. For the purposes of discussion, it will be explained from the following... Figure 1A The angle description method 400 of the terminal device 110 shown.

In some embodiments, at least one subband may include a first subband and a second subband, the first measurement report corresponding to the first subband in at least one measurement report may include an absolute value, and the second measurement report corresponding to the second subband in at least one measurement report may include an offset value relative to the absolute value. In some embodiments, the first subband and the second subband may have the same subband type.

[0116] In some embodiments, the terminal device 110 may perform CLI measurements on a non-SBFD time unit, wherein at least one measurement report may also indicate the measured CLI level of the CLI measurement, the measured CLI level may be indicated by an absolute value, and at least one measured CLI level may be indicated by at least one offset value relative to the absolute value.

[0117] In some embodiments, at least one subband may include a first type of subband and a second type of subband, and the first reporting range corresponding to the first type of subband and the second reporting range corresponding to the second type of subband may be different.

[0118] In some embodiments, at least one resource may be continuous in the frequency domain. In some embodiments, at least one resource may repeat periodically in the time domain. In some embodiments, configuration information may be received via RRC signaling. Alternatively or additionally, configuration information may be received via MAC CE. Alternatively or additionally, configuration information may be received via DCI.

[0119] Using method 400, the terminal device can provide a measurement report reflecting the CLI level of the subband (not limited to DL subband) in the SBFD scheme, which improves the efficiency and performance of communication.

[0120] Figure 5 The illustration shows a schematic diagram illustrating a method 500 implemented at a network device according to some other embodiments of the present disclosure. For discussion purposes, [the following will be discussed]. Figure 1A The angular description method 500 for the network device 120 shown.

[0121] like Figure 5 As shown, at block 510, network device 120 sends a resource indication to terminal device 110 for at least one resource for at least one CLI measurement. The at least one resource overlaps with multiple subbands in the SBFD time unit, and the multiple subbands have at least two subband types. At block 520, network device 120 sends configuration information to terminal device 110 indicating at least one subband among the multiple subbands for which at least one CLI measurement will be reported. At block 530, network device 120 receives from terminal device 110 at least one measurement report for reporting at least one CLI measurement.

[0122] In some embodiments, at least two subband types may include at least two of the following: DL subband type, guard band type, or UL subband type. In some embodiments, network device 120 may determine at least one of at least one resource and at least one subband based on determining that network device 120 and terminal device 110 support SBFD mode. In some embodiments, configuration information may also indicate that at least one subband will be measured.

[0123] In some embodiments, the configuration information may include a bitmap indicating at least one sub-band. In some embodiments, bits in the bitmap may correspond to a sub-band among a plurality of sub-bands in an SBFD time unit. In some embodiments, bits in the bitmap may correspond to one of the following: DL sub-band type, guard band type, or UL sub-band type.

[0131] Using method 500, network devices can obtain measurement reports reflecting CLI levels of subbands (not limited to DL subbands) in the SBFD scheme, which improves communication efficiency and performance.

[0132] In some embodiments, an apparatus capable of performing any of the methods of method 400 (e.g., terminal device 110) may include components for performing the corresponding steps of method 400. These components may be implemented in any suitable form. For example, the components may be implemented in a circuit system or a software module.
