[0179] To improve uplink (UL) coverage and throughput, the 3rd Generation Partnership Project (3GPP) has researched and standardized Subband Full Duplex (SBFD). Specifically, a carrier component (CC) is divided into multiple subbands (SBs) in the frequency domain on either the downlink (DL) or flexible (F) symbols. These multiple SBs include one uplink subband (UL subband) and at least one (one or two) downlink subbands (DL subbands). Network devices can transmit downlink signals in the downlink subband and simultaneously receive uplink signals in the uplink subband. When a symbol simultaneously contains both downlink and uplink subbands in the frequency domain, it is called an SBFD symbol. Similarly, when a time slot contains at least one SBFD symbol among its multiple symbols, the time slot may be called an SBFD time slot, as shown in Figure 1a. Figure 1a is a schematic diagram of a time slot according to an embodiment of the present disclosure, wherein time slot #0 is a downlink time slot containing 14 DL symbols, time slots #1-3 are SBFD time slots, each containing 14 SBFD symbols, and time slot #4 is a UL time slot containing 14 UL symbols.

[0180] In addition, there may be a guard band (GB) between the DL subband and the UL subband, which reduces the interference of DL signals in the DL subband to UL signals in the UL subband through frequency domain isolation.

[0181] In SBFD symbols, the GB and DL subbands cannot be used for UL transmission, while the UL subband can. The frequency domain range available for UL transmission in SBFD symbols is called the UL usable frequency domain range, which is the intersection of the UE's active uplink BWP and the uplink subband, also known as uplink usable physical resource blocks (UL usable PRBs). Similarly, downlink transmission has similar restrictions; downlink reception should be performed on downlink usable PRBs (DL usable PRBs). However, for Cross Link Interference (CLI) measurements, it can occur outside of downlink usable resources, such as the uplink subband, but must be performed on the downlink active BWP. For Received Signal Strength Indication (RSSI) measurements in Cross Link Interference, which measure power over specific time-frequency resources, it can measure the impact of one terminal device transmitting a signal in the uplink subband on another terminal device's measurement in the downlink subband. Directly, as shown in Figure 1b, the jammed terminal device 1 can measure RSSI on downlink subband A to characterize the impact of the jamming terminal device 2 transmitting signals on uplink subband A. Alternatively, the jammed terminal device 1 can directly measure RSSI on the same time-frequency resource (time-frequency resource 1) when the jamming terminal device 2 transmits signals on uplink subband A, thereby indirectly inferring the downlink reception impact of terminal device 2 on terminal device 1 through the measured RSSI magnitude.

[0182] Existing technologies define two types of CLI-RSSI measurement resources: one where the CLI-RSSI measurement resource is limited to a single downlink subband (as shown by measurement resource type #1 in Figure 1c), and another where the configured CLI-RSSI measurement resource can span two downlink subbands (as shown by measurement resource type #2 in Figure 1c). Further research is needed on how the terminal device performs CLI-RSSI measurements when the configured CLI-RSSI measurement resource spans multiple subbands.

[0183] The downlink and uplink time slots shown in Figures 1a-1c do not include the SBFD symbol.

[0184] The CLI-RSSI measurement reporting method provided in this disclosure will be further described below with reference to the accompanying drawings.

[0198] Figure 3a is one of the interactive schematic diagrams of a CLI-RSSI measurement reporting method according to an embodiment of the present disclosure. As shown in Figure 3a, the present disclosure relates to a CLI-RSSI measurement reporting method, which includes:

[0199] S301, The terminal device performs CLI-RSSI measurements on valid measurement resources among the configured cross-subband measurement resources and reports the CLI-RSSI results.

[0200] In some embodiments, the measurement resources across subbands include at least two of the following: uplink subband, downlink subband, or guard band.

[0201] As an example, cross-subband measurement resources include uplink subband, downlink subband, and guard band between uplink and downlink subband.

[0202] In some embodiments, the measurement resources across subbands can be measurement resources across downlink subbands, which include at least two downlink subbands, at least one uplink subband, and a guard band.

[0203] As an example, the measurement resources across subbands include at least two downlink subbands, one uplink subband, and a guard band between the uplink and downlink subbands.

[0204] In some embodiments, measurement resources across subbands are configured by the network device.

[0205] Optionally, measurement resources across subbands can be configured by network devices using measurement report configuration information.

[0206] Among them, cross-subband measurement resources can be configured by network devices through CLI-RSSI measurement resource set information (CLI-RSSI-MeasurementResourceSet) in the measurement report configuration information.

[0207] Among them, cross-subband measurement resources can be configured by network devices through CLI-RSSI measurement resource information (CLI-RSSI-MeasurementResource) in the measurement report configuration information.

[0208] Specifically, the measurement resources across subbands can be configured by the network device using at least one of the following parameters:

[0213] CLI-RSSI measures the number of symbols of the CLI-RSSI resource within a slot.

[0214] CLI-RSSI measures the periodicity and slot offset of the CLI-RSSI resource.

[0215] In some embodiments, valid measurement resources across subbands include at least one of the following:

[0216] The measurement resources across subbands overlap with the downlink available PRB frequency domain resources of the terminal equipment;

[0217] The overlapping frequency domain resources of cross-subband measurement resources and downlink available PRB of terminal equipment, as well as the guard band in cross-subband measurement resources;

[0218] The measurement resources across subbands overlap with the uplink available PRB frequency domain resources of the terminal equipment;

[0219] The measurement resources across subbands overlap with the uplink available PRB frequency domain resources of the terminal equipment, as well as the guard band in the measurement resources across subbands.

[0220] Among them, the overlapping frequency domain resources of the cross-subband measurement resources and the downlink usable PRBs of the terminal equipment can also be regarded as the remaining part of the cross-subband measurement resources after excluding the second resource (frequency domain resources other than downlink usable PRBs).

[0221] Among them, the overlapping frequency domain resources of the measurement resources across sub-bands and the uplink usable PRBs of the terminal equipment can also be regarded as the remaining part of the measurement resources across sub-bands after excluding the first resource (frequency domain resources outside the uplink usable PRBs).

[0222] As an example, the terminal device performs CLI-RSSI measurements on the overlapping frequency domain resources of the cross-subband measurement resources and the downlink available PRB of the terminal device, and reports the CLI-RSSI measurement results to the network device.

[0223] As an example, the terminal device performs CLI-RSSI measurements on the overlapping frequency domain resources of the measurement resources across subbands and the downlink available PRB of the terminal device, as well as the guard band of the measurement resources across subbands, and reports the CLI-RSSI measurement results to the network device.

[0224] As an example, the terminal device performs CLI-RSSI measurements on the overlapping frequency domain resources of the measurement resources across subbands and the uplink available PRB of the terminal device, and reports the CLI-RSSI measurement results to the network device.

[0225] As an example, the terminal device performs CLI-RSSI measurements on the overlapping frequency domain resources of the measurement resources across subbands and the uplink available PRB of the terminal device, as well as the guard band of the measurement resources across subbands, and reports the CLI-RSSI measurement results to the network device.

[0226] Figure 3b is a second interactive schematic diagram of a CLI-RSSI measurement reporting method according to an embodiment of the present disclosure. As shown in Figure 3b, the embodiments of the present disclosure relate to a CLI-RSSI measurement reporting method, which includes:

[0227] S311, the terminal equipment and network equipment determine the valid measurement resources among the configured cross-subband measurement resources.

[0228] In some embodiments, the terminal device and the network device may determine the valid measurement resources across subbands by at least one of the following methods:

[0229] When the measurement resources across subbands overlap with the uplink available physical resource blocks (PRBs) and / or downlink available PRBs of the terminal equipment in the same frequency domain, the valid measurement resources are determined based on the overlapping frequency domain resources.

[0230] Valid measurement resources are determined based on at least one of the default measurement method or the default measurement subband; wherein the default measurement method includes at least one of CLI-RSSI measurement on the downlink subband or CLI-RSSI measurement on the uplink subband; and the default measurement subband includes at least one of the uplink subband or the downlink subband.

[0231] Valid measurement resources are determined based on first indication information; wherein, the first indication information is used to indicate at least one of a first measurement mode or a first measurement subband; the first measurement mode includes at least one of performing CLI-RSSI measurement on a downlink subband or performing CLI-RSSI measurement on an uplink subband; the first measurement subband includes at least one of an uplink subband or a downlink subband.

[0232] Regarding the aforementioned default measurement method, the default measurement method can be a specific CLI-RSSI measurement method adopted by the terminal device when the terminal device and network device are pre-negotiated and the network device is configured with cross-subband measurement resources. Alternatively, the default measurement method can be obtained through predefinition, that is, the predefined measurement method is the default measurement method.

[0233] Regarding the aforementioned default measurement subband, the default measurement subband is pre-negotiated between the terminal device and the network device. When the network device is configured with cross-subband measurement resources, it represents the valid subband type for CLI-RSSI measurements performed by the terminal device. Alternatively, the default measurement subband can be obtained through predefinition; that is, the predefined measurement subband serves as the default measurement subband.

[0234] Optionally, the first measurement subband and the default measurement subband can directly indicate the effective measurement resources for the terminal device to perform CLI-RSSI measurements.

[0235] The first instruction information is sent by the network device.

[0236] In some embodiments, when the measurement resources across subbands overlap with the uplink available PRB and / or downlink available PRB of the terminal device in the same frequency domain, determining the valid measurement resources based on the overlapping frequency domain resources includes:

[0237] When the measurement resources across subbands overlap with the uplink available PRBs of the terminal device in the same frequency domain, at least one of the following shall be determined as valid measurement resources:

[0238] The cross-subband measurement resources overlap with the uplink available PRB frequency domain resources of the terminal equipment;

[0239] The measurement resources across subbands overlap with the uplink available PRB frequency domain resources of the terminal equipment, as well as the guard band in the measurement resources across subbands.

[0240] Among them, the overlapping frequency domain resources of the measurement resources across sub-bands and the uplink usable PRBs of the terminal equipment can also be regarded as the remaining part of the measurement resources across sub-bands after excluding the first resource (frequency domain resources outside the uplink usable PRBs).

[0241] In other words, when the measurement resources across subbands overlap with the uplink available PRB of the terminal device, the terminal device and the network device can identify the overlapping frequency domain resources as valid measurement resources. The terminal device can perform CLI-RSSI measurements on the valid measurement resources and report the CLI-RSSI measurement results, while the network device can obtain the CLI-RSSI measurement results reported by the terminal device on the valid measurement resources.

[0242] Alternatively, the terminal device and network device can identify the guard band in the overlapping frequency domain resources and cross-subband measurement resources as valid measurement resources. The terminal device can perform CLI-RSSI measurements on the valid measurement resources and report the CLI-RSSI measurement results, while the network device can obtain the CLI-RSSI measurement results reported by the terminal device on the valid measurement resources.

[0243] When cross-subband measurement resources overlap with downlink available PRBs of the terminal device in the same frequency domain, at least one of the following shall be determined as valid measurement resources:

[0244] The measurement resources across subbands overlap with the downlink available PRB frequency domain resources of the terminal equipment;

[0245] The measurement resources across subbands overlap with the downlink available PRB frequency domain resources of the terminal equipment, as well as the guard band in the measurement resources across subbands.

[0246] Among them, the overlapping frequency domain resources of the cross-subband measurement resources and the downlink usable PRBs of the terminal equipment can also be regarded as the remaining part of the cross-subband measurement resources after excluding the second resource (frequency domain resources other than downlink usable PRBs).

[0247] In other words, when the measurement resources across subbands overlap with the downlink available PRB of the terminal device, the terminal device and the network device can identify the overlapping frequency domain resources as valid measurement resources. The terminal device can perform CLI-RSSI measurements on the valid measurement resources and report the CLI-RSSI measurement results, while the network device can obtain the CLI-RSSI measurement results reported by the terminal device on the valid measurement resources.

[0248] Alternatively, the terminal device and network device can identify the guard band in the overlapping frequency domain resources and cross-subband measurement resources as valid measurement resources. The terminal device can perform CLI-RSSI measurements on the valid measurement resources and report the CLI-RSSI measurement results, while the network device can obtain the CLI-RSSI measurement results reported by the terminal device on the valid measurement resources.

[0249] When the measurement resources across subbands overlap with both the uplink available PRB and the downlink available PRB of the terminal device in the same frequency domain, at least one of the following shall be determined as valid measurement resources:

[0250] The measurement resources across subbands overlap with the uplink available PRB frequency domain resources of the terminal equipment;

[0251] The measurement resources across subbands overlap with the uplink available PRB frequency domain resources of the terminal equipment, as well as the guard band in the measurement resources across subbands;

[0252] The measurement resources across subbands overlap with the downlink available PRB frequency domain resources of the terminal equipment;

[0253] The overlapping frequency domain resources of cross-subband measurement resources and downlink available PRB of terminal equipment, as well as the guard band in cross-subband measurement resources;

[0254] The overlapping frequency domain resources of the measurement resources across subbands and the uplink available PRBs of the terminal equipment, and the overlapping frequency domain resources of the measurement resources across subbands and the downlink available PRBs of the terminal equipment;

[0255] The measurement resources across subbands overlap with the uplink available PRB frequency domain resources of the terminal equipment, the measurement resources across subbands overlap with the downlink available PRB frequency domain resources of the terminal equipment, and the guard band in the measurement resources across subbands.

[0256] The overlapping frequency domain resources of the cross-subband measurement resources and the uplink usable PRBs of the terminal equipment can also be considered as the remaining portion of the cross-subband measurement resources after excluding the first resource (frequency domain resources other than the uplink usable PRBs). Similarly, the overlapping frequency domain resources of the cross-subband measurement resources and the downlink usable PRBs of the terminal equipment can also be considered as the remaining portion of the cross-subband measurement resources after excluding the second resource (frequency domain resources other than the downlink usable PRBs).

[0257] As an example, when the measurement resources across subbands overlap with both the uplink available PRB and downlink available PRB of the terminal device, and the uplink subband is a valid measurement subband, the terminal device and network device can determine the overlapping frequency domain resources of the measurement resources across subbands and the uplink available PRB of the terminal device as valid resources, or determine the overlapping frequency domain resources of the measurement resources across subbands and the uplink available PRB of the terminal device, as well as the guard band in the measurement resources across subbands, as valid resources. The terminal device can perform CLI-RSSI measurements on these valid measurement resources and report the CLI-RSSI measurement results, while the network device can obtain the CLI-RSSI measurement results reported by the terminal device on these valid measurement resources.

[0258] As an example, when the measurement resources across subbands overlap with both the uplink and downlink available PRBs of the terminal device, and the downlink subband is a valid measurement subband, the terminal device and network device can determine the overlapping frequency domain resources of the measurement resources across subbands and the downlink available PRBs of the terminal device as valid resources. Alternatively, they can determine the overlapping frequency domain resources of the measurement resources across subbands and the downlink available PRBs of the terminal device, along with the guard band in the measurement resources across subbands, as valid resources. The terminal device can perform CLI-RSSI measurements on these valid measurement resources and report the CLI-RSSI measurement results, while the network device can obtain the CLI-RSSI measurement results reported by the terminal device on these valid measurement resources.

[0259] As an example, when the measurement resources across subbands overlap with both the uplink available PRB and the downlink available PRB of the terminal device, and both the uplink and downlink subbands are valid measurement subbands, the terminal device and the network device can determine at least one of the following as valid measurement resources:

[0260] The measurement resources across subbands overlap with the uplink available PRB frequency domain resources of the terminal equipment;

[0261] The measurement resources across subbands overlap with the uplink available PRB frequency domain resources of the terminal equipment, as well as the guard band in the measurement resources across subbands;

[0262] The measurement resources across subbands overlap with the downlink available PRB frequency domain resources of the terminal equipment;

[0263] The overlapping frequency domain resources of cross-subband measurement resources and downlink available PRB of terminal equipment, as well as the guard band in cross-subband measurement resources;

[0264] The overlapping frequency domain resources of the measurement resources across subbands and the uplink available PRBs of the terminal equipment, and the overlapping frequency domain resources of the measurement resources across subbands and the downlink available PRBs of the terminal equipment;

[0265] The measurement resources across subbands overlap with the uplink available PRB frequency domain resources of the terminal equipment, the measurement resources across subbands overlap with the downlink available PRB frequency domain resources of the terminal equipment, and the guard band in the measurement resources across subbands.

[0266] After a valid measurement resource is identified, the terminal device can perform CLI-RSSI measurements on that valid measurement resource and report the CLI-RSSI measurement results. The network device can then obtain the CLI-RSSI measurement results reported by the terminal device on that valid measurement resource.

[0267] The overlapping frequency domain resources of the cross-subband measurement resources and the uplink usable PRBs of the terminal equipment can also be considered as the remaining portion of the cross-subband measurement resources after excluding the first resource (frequency domain resources other than the uplink usable PRBs). Similarly, the overlapping frequency domain resources of the cross-subband measurement resources and the downlink usable PRBs of the terminal equipment can also be considered as the remaining portion of the cross-subband measurement resources after excluding the second resource (frequency domain resources other than the downlink usable PRBs).

[0268] In some embodiments, the first instruction information is sent from the network device to the terminal device.

[0269] Optionally, the first indication information is associated with measurement report information configuration information. As an example, the network device may send CLI-RSSI measurement report configuration information (CLI-RSSI-ReportConfig) to the terminal device, which includes the first indication information.

[0270] The CLI-RSSI measurement report configuration information may include a report quality information element (ReportQuantity), which carries first indication information.

[0271] Optionally, the first indication information is associated with configured cross-subband measurement resources. As an example, the network device may send CLI-RSSI Measurement Resource Set information to the terminal device, which includes the first indication information.

[0272] That is, when a network device configures cross-subband measurement resources through CLI-RSSI measurement resource set information, it indicates the first measurement mode and / or the first measurement subband through the first indication information in CLI-RSSI measurement resource set information.

[0273] Alternatively, the network device may send CLI-RSSI measurement resource information (CLI-RSSI-MeasurementResource) to the terminal device, which includes first indication information.

[0274] That is, when a network device configures cross-subband measurement resources through CLI-RSSI measurement resource information, it indicates the first measurement mode and / or the first measurement subband through the first indication information in the CLI-RSSI measurement resource information.

[0275] Optionally, the network device may send downlink control information (DCI) or higher-layer signaling to the terminal device, wherein the DCI or higher-layer signaling includes first indication information.

[0276] That is, network devices can send DCI or higher-layer signaling to terminal devices to indicate the first measurement mode and / or the first measurement subband.

[0277] Alternatively, the first instruction information can also be carried in the system message sent by the network device to the terminal device.

[0278] In some embodiments, when determining measurement resources based on first indication information, if the first indication information includes a first measurement mode and the first measurement mode includes CLI-RSSI measurement on a downlink subband, and / or if the first indication information includes a first measurement subband and the first measurement subband includes a downlink subband, at least one of the following will be determined as a valid measurement resource:

[0279] The measurement resources across subbands overlap with the downlink available PRB frequency domain resources of the terminal equipment;

[0280] The measurement resources across subbands overlap with the downlink available PRR frequency domain resources of the terminal equipment, as well as the guard band in the measurement resources across subbands.

[0281] In other words, when the network device instructs the terminal device to perform CLI-RSSI measurements on a downlink subband via the first indication information, and / or when the measurement subband is a downlink subband, the terminal device and the network device can determine the overlapping frequency domain resources of the cross-subband measurement resources and the downlink available PRB of the terminal device as valid measurement resources, or they can determine the guard band in the overlapping frequency domain resources and the cross-subband measurement resources as valid measurement resources. The terminal device can perform CLI-RSSI measurements on these valid measurement resources and report the CLI-RSSI measurement results, and the network device can obtain the CLI-RSSI measurement results reported by the terminal device on these valid measurement resources.

[0282] When the first indication information includes a first measurement mode and the first measurement mode includes CLI-RSSI measurement on the uplink subband, and / or when the first indication information includes a first measurement subband and the first measurement subband includes the uplink subband, at least one of the following will be determined as a valid measurement resource:

[0283] The measurement resources across subbands overlap with the uplink available PRB frequency domain resources of the terminal equipment;

[0284] The measurement resources across subbands overlap with the uplink available PRR frequency domain resources of the terminal equipment, as well as the guard band in the measurement resources across subbands.

[0285] In other words, when the network device instructs the terminal device to perform CLI-RSSI measurements on the uplink subband via the first indication information, and / or when the measurement subband is an uplink subband, the terminal device and the network device can determine the overlapping frequency domain resources of the measurement resources across the subband and the uplink available PRB of the terminal device as valid measurement resources, or they can determine the guard band in the overlapping frequency domain resources and the measurement resources across the subband as valid measurement resources. The terminal device can perform CLI-RSSI measurements on the valid measurement resources and report the CLI-RSSI measurement results, and the network device can obtain the CLI-RSSI measurement results reported by the terminal device on the valid measurement resources.

[0286] The overlapping frequency domain resources of the cross-subband measurement resources and the uplink usable PRBs of the terminal equipment can also be considered as the remaining portion of the cross-subband measurement resources after excluding the first resource (frequency domain resources other than the uplink usable PRBs). Similarly, the overlapping frequency domain resources of the cross-subband measurement resources and the downlink usable PRBs of the terminal equipment can also be considered as the remaining portion of the cross-subband measurement resources after excluding the second resource (frequency domain resources other than the downlink usable PRBs).

[0287] In some embodiments, when determining a valid measurement resource based on at least one of the default measurement method or the default measurement subband, when the default measurement method includes CLI-RSSI measurement on the downlink subband, and / or when the default measurement subband includes the downlink subband, at least one of the following is determined as a valid measurement resource:

[0288] The measurement resources across subbands overlap with the downlink available PRB frequency domain resources of the terminal equipment;

[0289] The measurement resources across subbands overlap with the downlink available PRR frequency domain resources of the terminal equipment, as well as the guard band in the measurement resources across subbands.

[0290] In other words, when the terminal device and network device have pre-negotiated and the network device has configured cross-subband measurement resources, and the specific method of CLI-RSSI measurement adopted by the terminal device is to perform CLI-RSSI measurement on the downlink subband, and / or, when the terminal device and network device have pre-negotiated and the network device has configured cross-subband measurement resources, and the effective subband type for CLI-RSSI measurement by the terminal device is the downlink subband, the terminal device and network device can determine the overlapping frequency domain resources of the cross-subband measurement resources and the downlink available PRB of the terminal device as effective measurement resources, or they can determine the guard band in the overlapping frequency domain resources and the cross-subband measurement resources as effective measurement resources. The terminal device can perform CLI-RSSI measurement on the effective measurement resources and report the CLI-RSSI measurement results, and the network device can obtain the CLI-RSSI measurement results reported by the terminal device on the effective measurement resources.

[0291] When the default measurement method includes CLI-RSSI measurement on the uplink subband, and / or when the default measurement subband includes the uplink subband, at least one of the following will be determined as a valid measurement resource:

[0292] The measurement resources across subbands overlap with the uplink available PRB frequency domain resources of the terminal equipment;

[0293] The measurement resources across subbands overlap with the uplink available PRR frequency domain resources of the terminal equipment, as well as the guard band in the measurement resources across subbands.

[0294] In other words, when the terminal device and network device have pre-negotiated and the network device is configured with cross-subband measurement resources, and the specific method of CLI-RSSI measurement adopted by the terminal device is to perform CLI-RSSI measurement on the uplink subband, and / or, when the terminal device and network device have pre-negotiated and the network device is configured with cross-subband measurement resources, and the effective subband type for CLI-RSSI measurement by the terminal device is the uplink subband, the terminal device and network device can determine the overlapping frequency domain resources of the cross-subband measurement resources and the uplink available PRB of the terminal device as effective measurement resources, or they can determine the guard band in the overlapping frequency domain resources and the cross-subband measurement resources as effective measurement resources. The terminal device can perform CLI-RSSI measurement on the effective measurement resources and report the CLI-RSSI measurement results, and the network device can obtain the CLI-RSSI measurement results reported by the terminal device on the effective measurement resources.

[0295] The overlapping frequency domain resources of the cross-subband measurement resources and the uplink usable PRBs of the terminal equipment can also be considered as the remaining portion of the cross-subband measurement resources after excluding the first resource (frequency domain resources other than the uplink usable PRBs). Similarly, the overlapping frequency domain resources of the cross-subband measurement resources and the downlink usable PRBs of the terminal equipment can also be considered as the remaining portion of the cross-subband measurement resources after excluding the second resource (frequency domain resources other than the downlink usable PRBs).

[0296] The default measurement method and the default measurement sub-band can be obtained through predefinition.

[0297] It should be noted that terminal devices and network devices can use any one or more of the above methods to determine valid measurement resources, and the methods used by terminal devices and network devices to determine valid measurement resources are the same.

[0298] For example, after the network device configures cross-subband measurement resources for the terminal device, the network device sends a first indication message to the terminal device. The terminal device and the network device can determine the valid measurement resources among the cross-subband measurement resources based on the first indication message and adopt the same determination method.

[0299] For example, after a network device configures cross-subband measurement resources for a terminal device, the network device and the terminal device can determine the valid measurement resources in the cross-subband measurement resources by adopting the same determination method based on at least one of the default measurement method (predefined measurement method) or the default measurement subband (predefined measurement subband).

[0300] For example, after a network device configures cross-subband measurement resources for a terminal device, the network device and the terminal device can use PRBs for cross-subband measurement resources and uplink of the terminal device.

[0301] For example, after the network device configures cross-subband measurement resources for the terminal device, if the network device does not send the first indication information to the terminal device, the network device and the terminal device can determine the valid measurement resources in the cross-subband measurement resources by adopting the same determination method according to at least one of the default measurement method (predefined measurement method) or the default measurement subband (predefined measurement subband).

[0302] S312, the terminal device performs CLI-RSSI measurements on valid measurement resources and reports the CLI-RSSI measurement results to the network device.

[0303] In some embodiments, the terminal device can perform CLI-RSSI measurements on a determined valid measurement resource and report the CLI-RSSI measurement results, and the network device can obtain the CLI-RSSI measurement results reported by the terminal device on the valid measurement resource.

[0304] The communication method involved in the embodiments of this disclosure may include at least one of S311-S312. For example, any one of S311-S312 may be implemented as an independent embodiment, and any combination of multiple steps in S311-S312 may be implemented as an independent embodiment, but is not limited thereto.

[0305] It should be noted that the measurement resources across subbands in this embodiment can also be referred to as CLI-RSSI measurement resources across subbands.

[0306] The CLI-RSSI measurement reporting method performed by the terminal device is explained below with specific examples.

[0307] The UE receives the indication information, determines the valid resources for CLI-RSSI measurement across subbands based on the indication information, performs the measurement on the valid resources, and reports the measurement results.

[0308] The indication information specifies a measurement method, which includes one or more of the following methods:

[0309] CLI-RSSI measurements are performed in the downlink subband (the effective measurement resources are the overlapping portion of the configured cross-subband CLI-RSSI measurement resources and the UE DL usable PRBs / the remaining portion of the configured cross-subband CLI-RSSI measurement resources after excluding the second resource (frequency domain resources other than downlink usable PRBs));

[0310] CLI-RSSI measurements are performed in the uplink subband (the effective measurement resources are the overlapping portion of the configured cross-subband CLI-RSSI measurement resources and the UE UL usable PRBs / the remaining portion of the configured cross-subband CLI-RSSI measurement resources after excluding the first resource (frequency domain resources other than uplink usable PRBs)).

[0311] The indication information specifies a subband type, and CLI-RSSI measurements on the subband of the indicated subband type are valid resources, including:

[0312] Downlink subband (effective measurement resources are the overlapping portion of the configured cross-subband CLI-RSSI measurement resources and UE DL usable PRBs / the remaining portion of the configured cross-subband CLI-RSSI measurement resources after excluding the second resource (frequency domain resources other than downlink usable PRBs);

[0313] Uplink subband (effective measurement resources are the overlapping portion of the configured cross-subband CLI-RSSI measurement resources and UE UL usable PRBs / the remaining portion of the configured cross-subband CLI-RSSI measurement resources after excluding the first resource (frequency domain resources other than uplink usable PRBs)).

[0314] This indication information is associated with CLI-RSSI measurement report configuration information (which is included in the CLI-RSSI measurement report configuration information and is associated with CLI-RSSI measurement resources across subbands).

[0315] This indication information is associated with CLI-RSSI measurement resource set information / CLI-RSSI measurement resource information (the indication information is directly included in the CLI-RSSI measurement resource set information / CLI-RSSI measurement resource information used to configure CLI-RSSI measurement resources across subbands).

[0316] The UE performs measurements on valid CLI-RSSI resources and reports the CLI-RSSI measurement results.

[0317] The CLI-RSSI measurement reporting method performed by network devices is explained below with specific examples.

[0318] The base station sends an indication message, determines the valid resources for CLI-RSSI measurement across subbands based on the indication message, and obtains the CLI-RSSI measurement report reported by the UE on the valid resources.

[0319] The indication information specifies a measurement method, which includes one or more of the following methods:

[0320] CLI-RSSI measurements are performed in the downlink subband (the effective measurement resources are the overlapping portion of the configured cross-subband CLI-RSSI measurement resources and the UE DL usable PRBs / the remaining portion of the configured cross-subband CLI-RSSI measurement resources after excluding the second resource (frequency domain resources other than downlink usable PRBs));

[0321] CLI-RSSI measurements are performed in the uplink subband (the effective measurement resources are the overlapping portion of the configured cross-subband CLI-RSSI measurement resources and the UE UL usable PRBs / the remaining portion of the configured cross-subband CLI-RSSI measurement resources after excluding the first resource (frequency domain resources other than uplink usable PRBs)).

[0322] The indication information specifies a subband type, and CLI-RSSI measurements on the subband of the indicated subband type are valid resources, including:

[0323] Downlink subband (effective measurement resources are the overlapping portion of the configured cross-subband CLI-RSSI measurement resources and UE DL usable PRBs / the remaining portion of the configured cross-subband CLI-RSSI measurement resources after excluding the second resource (frequency domain resources other than downlink usable PRBs);

[0324] Uplink subband (effective measurement resources are the overlapping portion of the configured cross-subband CLI-RSSI measurement resources and UE UL usable PRBs / the remaining portion of the configured cross-subband CLI-RSSI measurement resources after excluding the first resource (frequency domain resources other than uplink usable PRBs)).

[0325] This indication information is associated with CLI-RSSI measurement report configuration information (which is included in the CLI-RSSI measurement report configuration information and is associated with CLI-RSSI measurement resources across subbands).

[0326] This indication information is associated with CLI-RSSI measurement resource set information / CLI-RSSI measurement resource information (the indication information is directly included in the CLI-RSSI measurement resource set information / CLI-RSSI measurement resource information used to configure CLI-RSSI measurement resources across subbands).

[0327] The CLI-RSSI measurement reporting method provided in this disclosure is illustrated below with some examples.

[0328] Example 1:

[0329] The network device sends a first indication message to the terminal device, which indicates a measurement method.

[0330] The first indication information is in CLI-RSSI resource information (CLI-RSSI-MeasurementResource) or in CLI-RSSI resource set information (CLI-RSSI-MeasurementResourceSet).

[0331] The first indication information is an information element (IE) defined in CLI-RSSI-MeasurementResource (CLI-RSSI-MeasurementResourceSet), which indicates whether the terminal device will perform measurements based on the downlink subband or the uplink subband when the network device configures cross-subband CLI-RSSI measurement resources for the terminal device.

[0332] When the indication is based on downlink subband measurements, as shown in Figure 4a, the overlapping portion of the configured cross-subband CLI-RSSI measurement resources and UE DL usable PRBs is the valid measurement resource. In other words, the remaining portion of the configured cross-subband CLI-RSSI measurement resources after excluding the second resource (frequency domain resources other than downlink usable PRBs) is the valid measurement resource.

[0333] When the indication is based on uplink subband measurements, as shown in Figure 4b, the overlapping portion of the configured cross-subband CLI-RSSI measurement resources and UE UL usable PRBs is the valid measurement resource. In other words, the remaining portion of the configured cross-subband CLI-RSSI measurement resources after excluding the first resource (frequency domain resources other than uplink usable PRBs) is the valid measurement resource.

[0334] If Method #1 is predefined as performing CLI-RSSI measurements on the downlink subband, and Method #3 is predefined as performing CLI-RSSI measurements on the uplink subband, the first indication information can indicate the measurement method as CLI-RSSI measurement on the downlink subband via Method #1, and as CLI-RSSI measurement on the uplink subband via Method #3. When the network device does not send this first indication information, the terminal device can use either Method #1 or Method #3 as the default (predefined) measurement method and determine the valid measurement resources based on the default (predefined) measurement method.

[0335] Example 2:

[0336] The network device sends a first indication message to the terminal device. The first indication message is configured in the CLI-RSSI measurement report configuration information associated with the CLI-RSSI resource (resource set).

[0337] The CLI-RSSI measurement report configuration information can be CSI-ReportConfig under the CSI framework.

[0338] Network devices can configure specific measurement methods in the CLI-RSSI measurement report configuration information, allowing terminal devices and network devices to determine valid measurement resources based on the measurement method. For example, when CLI-RSSI measurement is configured in reportQuantity under CSI-ReportConfig (i.e., when the selected IE is CLI-RSSI), a first indication message is added below it.

[0339] The first indication information indicates whether the terminal device will perform measurements based on the downlink subband or the uplink subband when the network device configures cross-subband CLI-RSSI measurement resources for the terminal device. When the indication is based on the downlink subband, as shown in Figure 4a, the overlapping portion of the configured cross-subband CLI-RSSI measurement resources and the UE DL usable PRBs is the valid measurement resource. In other words, the remaining portion of the configured cross-subband CLI-RSSI measurement resources after excluding the second resource (frequency domain resources other than downlink usable PRBs) is the valid measurement resource. When the indication is based on uplink subband measurements, as shown in Figure 4b, the overlapping portion of the configured cross-subband CLI-RSSI measurement resources and UE UL usable PRBs is the valid measurement resource. In other words, the remaining portion of the configured cross-subband CLI-RSSI measurement resources after excluding the first resource (frequency domain resources other than uplink usable PRBs) is the valid measurement resource.

[0340] If Method #1 is predefined as performing CLI-RSSI measurements on the downlink subband, and Method #3 is predefined as performing CLI-RSSI measurements on the uplink subband, the first indication information can indicate that the measurement method is CLI-RSSI measurement on the downlink subband through Method #1, and that the measurement method is CLI-RSSI measurement on the uplink subband through Method #3. When the network device does not send this first indication information, that is, when the CLI-RSSI measurement report configuration information does not include the first indication information, the measurement method can be determined based on the default mode or the predefined mode. That is, either Method #1 or Method #3 is taken as the default measurement method, and the valid measurement resources are determined according to the default measurement method.

[0341] Alternatively, the measurement method can be defined when selecting reportQuantity under CLI-RSSI measurement report configuration information (such as SI-ReportConfig). For example, cli-RSSI-M1 or cli-RSSI-M3 can be directly defined in reportQuantity, with the corresponding measurement methods being Method#1 or Method#3.

[0342] Example 3:

[0343] The network device sends a first indication message to the terminal device. The first indication message is configured in the CLI-RSSI measurement report configuration information associated with the CLI-RSSI resource (resource set).

[0344] The first indication information indicates a sub-band type (measurement sub-band), and the indication information is in the CLI-RSSI resource (resource set) information.

[0345] The first indication information is an information element (IE) defined in CLI-RSSI-MeasurementResource (CLI-RSSI-MeasurementResourceSet), indicating whether the configured CLI-RSSI measurement resources are valid on the uplink subband (uplink available PRBs) or the downlink subband (uplink available PRBs) when the network device configures cross-subband CLI-RSSI measurement resources to the terminal device, and whether the measurement subband is the uplink subband or the downlink subband.

[0346] When the CLI-RSSI measurement resources are indicated to be valid in the downlink subband, as shown in Figure 4a, the overlapping portion of the configured cross-subband CLI-RSSI measurement resources and the UE DL usable PRBs is a valid measurement resource. In other words, the remaining portion of the configured cross-subband CLI-RSSI measurement resources after excluding the second resource (frequency domain resources other than downlink usable PRBs) is a valid measurement resource.

[0347] When the CLI-RSSI measurement resources are indicated to be valid in the uplink subband, as shown in Figure 4b, the overlapping portion of the configured cross-subband CLI-RSSI measurement resources and the UE UL usable PRBs is a valid measurement resource. In other words, the remaining portion of the configured cross-subband CLI-RSSI measurement resources after excluding the first resource (frequency domain resources other than the uplink usable PRBs) is a valid measurement resource.

[0348] Example 4:

[0349] The network device sends a first indication message to the terminal device. The first indication message is configured in the CLI-RSSI measurement report configuration information associated with the CLI-RSSI resource (resource set).

[0350] The CLI-RSSI measurement report configuration information can be CSI-ReportConfig under the CSI framework.

[0351] Network devices can configure valid measurement subbands in the CLI-RSSI measurement report configuration information, allowing terminal devices and network devices to determine valid measurement resources based on these valid measurement subbands. For example, when CLI-RSSI measurement is configured in reportQuantity under CSI-ReportConfig (i.e., when the selected IE is CLI-RSSI), a first indication message is added below it.

[0352] The first indication information selects one from {downlink subband (downlink available PRBs), uplink subband (uplink available PRBs)}. When the first indication information indicates downlink subband (downlink available PRBs), as shown in Figure 4a, the overlapping portion of the configured cross-subband CLI-RSSI measurement resources and UE DL usable PRBs is the valid measurement resource. In other words, the remaining portion of the configured cross-subband CLI-RSSI measurement resources after excluding the second resource (frequency domain resources other than downlink available PRBs) is the valid measurement resource. When the first indication information indicates an uplink subband (uplink usable PRBs), as shown in Figure 4b, the overlapping portion of the configured cross-subband CLI-RSSI measurement resources and the UE UL usable PRBs is a valid measurement resource. In other words, the remaining portion of the configured cross-subband CLI-RSSI measurement resources after excluding the first resource (frequency domain resources other than uplink usable PRBs) is a valid measurement resource.

[0353] Specifically, the terminal device and network device can pre-negotiate whether the valid measurement subband is a downlink subband or an uplink subband, and the first indication information can be selected from either one. When the network device does not send the first indication information, that is, when the CLI-RSSI measurement report configuration information does not include the first indication information, the valid measurement subband can be determined based on (default mode), that is, either the downlink subband (downlink available PRBs) or the uplink subband (uplink available PRBs) is taken as the default measurement subband (valid measurement subband), and the valid measurement resources are determined accordingly.

[0354] Alternatively, a valid measurement subband can be defined when selecting reportQuantity under CLI-RSSI measurement report configuration information (such as SI-ReportConfig). For example, cli-RSSI-DL or cli-RSSI-UL can be directly defined in reportQuantity, and the corresponding valid measurement subband is the downlink subband or the uplink subband.

[0355] It should be noted that the uplink and downlink time slots shown in Figures 4a and 4b do not include SBFD symbols. The cross-subband measurement resources configured in this embodiment are the measurement resources on the SBFD symbols.

[0356] Figure 5a is a schematic flowchart of a CLI-RSSI measurement reporting method according to an embodiment of the present disclosure. As shown in Figure 5a, the CLI-RSSI measurement reporting method according to the embodiment of the present disclosure can be executed by a terminal device, and the method includes:

[0357] S511 performs CLI-RSSI measurements on valid measurement resources among the configured cross-subband measurement resources and reports the CLI-RSSI measurement results.

[0358] In some embodiments, the method further includes:

[0359] Identify effective measurement resources.

[0360] In some embodiments, determining a valid measurement resource includes at least one of the following:

[0361] When the measurement resources across subbands overlap with the uplink available physical resource blocks (PRBs) and / or downlink available PRBs of the terminal equipment in the same frequency domain, the valid measurement resources are determined based on the overlapping frequency domain resources.

[0362] Valid measurement resources are determined based on at least one of the default measurement method or the default measurement subband; wherein the default measurement method includes at least one of CLI-RSSI measurement on the downlink subband or CLI-RSSI measurement on the uplink subband; and the default measurement subband includes at least one of the uplink subband or the downlink subband.

[0363] Receive first indication information and determine valid measurement resources based on the first indication information; wherein, the first indication information is used to indicate at least one of a first measurement mode or a first measurement subband; the first measurement mode includes at least one of performing CLI-RSSI measurement on a downlink subband or performing CLI-RSSI measurement on an uplink subband; the first measurement subband includes at least one of an uplink subband or a downlink subband.

[0364] Regarding the aforementioned default measurement method, the default measurement method can be a specific CLI-RSSI measurement method adopted by the terminal device when the terminal device and network device are pre-negotiated and the network device is configured with cross-subband measurement resources. Alternatively, the default measurement method can be obtained through predefinition, that is, the predefined measurement method is the default measurement method.

[0365] Regarding the aforementioned default measurement subband, the default measurement subband is pre-negotiated between the terminal device and the network device. When the network device is configured with cross-subband measurement resources, it represents the valid subband type for CLI-RSSI measurements performed by the terminal device. Alternatively, the default measurement subband can be obtained through predefinition; that is, the predefined measurement subband serves as the default measurement subband.

[0366] In some embodiments, receiving first indication information includes at least one of the following:

[0367] Receive CLI-RSSI measurement report configuration information, which includes first indication information;

[0368] Receive CLI-RSSI measurement resource set information, which includes first indication information;

[0369] Receive CLI-RSSI measurement resource information, which includes first indication information;

[0370] Receive downlink control information (DCI) or higher-layer signaling, including first indication information.

[0371] In some embodiments, CLI-RSSI measurement report configuration information includes a report quality information element, which includes first indication information.

[0372] In some embodiments, when the measurement resources across subbands overlap with the uplink available physical resource blocks (PRBs) and / or downlink available PRBs of the terminal device in the same frequency domain, determining the valid measurement resources based on the overlapping frequency domain resources includes:

[0373] When cross-subband measurement resources overlap with uplink or downlink available PRBs of the terminal device in terms of frequency domain resources, at least one of the following shall be determined as valid measurement resources:

[0374] Overlapping frequency domain resources;

[0375] Guard bands in overlapping frequency domain resources and cross-subband measurement resources;

[0376] When the measurement resources across subbands overlap with both the uplink available PRB and the downlink available PRB of the terminal device in the same frequency domain, at least one of the following shall be determined as valid measurement resources:

[0377] The measurement resources across subbands overlap with the uplink available PRB frequency domain resources of the terminal equipment;

[0378] The measurement resources across subbands overlap with the uplink available PRB frequency domain resources of the terminal equipment, as well as the guard band in the measurement resources across subbands;

[0379] The measurement resources across subbands overlap with the downlink available PRB frequency domain resources of the terminal equipment;

[0380] The overlapping frequency domain resources of cross-subband measurement resources and downlink available PRB of terminal equipment, as well as the guard band in cross-subband measurement resources;

[0381] The overlapping frequency domain resources of the measurement resources across subbands and the uplink available PRBs of the terminal equipment, and the overlapping frequency domain resources of the measurement resources across subbands and the downlink available PRBs of the terminal equipment;

[0382] The measurement resources across subbands overlap with the uplink available PRB frequency domain resources of the terminal equipment, the measurement resources across subbands overlap with the downlink available PRB frequency domain resources of the terminal equipment, and the guard band in the measurement resources across subbands.

[0383] The overlapping frequency domain resources of the cross-subband measurement resources and the uplink usable PRBs of the terminal equipment can also be considered as the remaining portion of the cross-subband measurement resources after excluding the first resource (frequency domain resources other than the uplink usable PRBs). Similarly, the overlapping frequency domain resources of the cross-subband measurement resources and the downlink usable PRBs of the terminal equipment can also be considered as the remaining portion of the cross-subband measurement resources after excluding the second resource (frequency domain resources other than the downlink usable PRBs).

[0384] In some embodiments, determining valid measurement resources based on at least one of the default measurement method or default measurement subbands includes:
