Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to a method, apparatus, device, medium, and program product for measuring cross-link interference of user equipment. Background Technology

[0002] With network evolution, Sub-band Full Duplex (SBFD) technology has gradually emerged, aiming to allow devices to simultaneously transmit and receive on different sub-bands of the same spectrum. Traditional Time Division Duplex (TDD) has fixed uplink and downlink frequencies in the frequency domain, with cross-transmission in the time domain; traditional Frequency Division Duplex (FDD) has fixed uplink and downlink frequencies in the time domain, with cross-transmission in the frequency domain.

[0003] Based on this, sub-band full-duplex technology enables uplink and downlink resources to be transmitted crosswise in the time and frequency domains, achieving the effects of time division duplex (TDD) and frequency division duplex (FDD). It combines the advantages of TDD and FDD, makes full use of spectrum resources, and improves the utilization and flexibility of spectrum resources.

[0004] However, the use of sub-band full-duplex technology can cause self-interference problems, especially cross-link interference between user equipment. Furthermore, related technologies lack methods for accurately identifying and measuring cross-link interference between user equipment.

[0045] Figure 1 A flowchart of a user equipment cross-link interference measurement method according to an embodiment of this disclosure is shown, as follows: Figure 1 As shown, applied to a user equipment, the method includes:

[0047] As described above, the embodiments of this disclosure perform cross-link interference measurement through user equipment. These embodiments can accurately identify and measure cross-link interference between user equipment, thereby improving interference measurement accuracy and system performance.

[0048] In one embodiment of this disclosure, in a scenario involving sub-band full-duplex interference measurement for frequency range 1 and frequency range 2, it is difficult to completely avoid the impact on adjacent channels during actual transmission due to the propagation characteristics of radio signals. Therefore, user equipment can perform cross-link interference (CLI) measurements to help the network optimize resource allocation, adopt appropriate interference coordination strategies, and thereby improve the overall system performance and reliability.

[0049] Frequency Range 1 (FR1) has a frequency range of 410MHz-7125MHz, while Frequency Range 2 (FR2) refers to the millimeter wave band, which is the band above 24.25GHz. FR2 includes FR2-1 and FR2-2. The frequency range of the FR2-1 band is 24250MHz-52600MHz, and the frequency range of the FR2-2 band is 52600MHz-71000MHz.

[0050] In one embodiment of this disclosure, S102 includes: performing a measurement of a first measurement quantity, and / or performing a measurement of a second measurement quantity.

[0051] In one embodiment of this disclosure, S102 includes: performing a measurement of a first measurement quantity based on a first resource, and / or performing a measurement of a second measurement quantity based on a second resource.

[0052] In one embodiment of this disclosure, the first resource and the second resource may be specific resource configurations of Layer 1 (L1), that is, specific resource configurations of the physical layer.

[0053] In one embodiment of this disclosure, S102 includes: performing a measurement of a first measurement quantity during a first measurement period or a first time delay; and / or performing a measurement of a second measurement quantity during a second measurement period or a second time delay.

[0054] In one embodiment of this disclosure, the method further includes: sending a first measurement report during a first measurement period or a first delay; and / or sending a second measurement report during a second measurement period or a second delay.

[0055] Specifically, the measurement of the first measurement quantity can be performed within the first measurement cycle or the first time delay; the first measurement report can be sent at the end of the first measurement cycle or the first time delay; the measurement of the second measurement quantity can be performed within the second measurement cycle or the second time delay; and the second measurement report can be sent at the end of the second measurement cycle or the second time delay.

[0056] Specifically, Figure 2 A flowchart of another user equipment cross-link interference measurement method according to an embodiment of this disclosure is shown, such as... Figure 2 As shown, the method includes:

[0057] S202, perform a measurement of a first measurement quantity based on a configured first resource, and / or perform a measurement of a second measurement quantity based on a configured second resource, wherein the first measurement quantity is used to reflect the interference level of the terminal's uplink channel, and the second measurement quantity is used to reflect the interference level of the terminal's downlink channel.

[0058] S204, send a first measurement report and / or a second measurement report, wherein the first measurement report includes: a first measurement quantity, and the second measurement report includes: a second measurement quantity.

[0059] As described above, in this embodiment of the present disclosure, the user equipment performs a first measurement based on a first resource and / or a second measurement based on a second resource. The obtained first and / or second measurements can be included in the corresponding measurement reports, and then the first and / or second measurement reports can be sent. This embodiment of the present disclosure can accurately identify and measure cross-link interference between user equipments, thereby improving interference measurement accuracy and system performance.

[0060] In one embodiment of this disclosure, the user equipment performs Layer 1-based cross-link interference measurement based on configured resources, defines the Layer 1-based cross-link interference measurement period and measurement accuracy, and the Layer 1-based cross-link interference measurement accuracy is better than the Layer 3 (i.e., network layer) measurement accuracy. On the one hand, this is beneficial for terminals to measure and identify cross-link interference between terminals, and on the other hand, it helps to improve measurement accuracy and improve system performance.

[0061] In one embodiment of this disclosure, it further includes any one or more combinations of the following: a first measurement quantity and / or a second measurement quantity in an active bandwidth portion (BWP); a first resource and / or a second resource in an active bandwidth portion (BWP), wherein the first resource is a measurement resource for the first measurement quantity, and the second resource is a measurement resource for the second measurement quantity; the first measurement quantity and / or the second measurement quantity are used for intra-frequency measurement and / or inter-frequency measurement.

[0062] In one embodiment of this disclosure, the Bandwidth Part (BWP) allows a user device to operate on only a portion of the carrier bandwidth, rather than the entire carrier bandwidth, for a specific period of time. An active BWP is the BWP currently activated for communication. An active BWP can be an active downlink BWP, a BWP including a downlink subband, or a BWP including an uplink subband. When the active BWP includes either a downlink subband or an uplink subband, spectrum resources can be utilized more flexibly, especially in scenarios requiring support for different types of services or applications.

[0063] In one embodiment of this disclosure, the first measurement and / or the second measurement are applicable to intra-frequency measurement and / or inter-frequency measurement in Radio Resource Control (RRC) connected state.

[0064] Intra-frequency measurements refer to measurements of the signal quality of a serving cell or different cells within the same frequency range, while inter-frequency measurements involve measurements performed between different frequency ranges. In RRC connected mode, user equipment (UE) performs intra-frequency or inter-frequency measurement tasks according to network instructions to ensure service quality and optimize user experience. For example, if the network needs to know the status of other cells in the same frequency band around the UE to prepare for a possible handover, it may instruct the UE to perform intra-frequency measurements; if the network is preparing for a cross-frequency band handover, it may instruct the UE to perform inter-frequency measurements.

[0065] In one embodiment of this disclosure, the first measurement is the probe reference signal received power or the layer-one probe reference signal received power.

[0066] In one embodiment of this disclosure, the Sounding Reference Signal-Reference Signal Received Power (SRS-RSRP) can be defined as the linear average of the power contribution (in W) of the resource elements carrying the sounding reference signal. The sounding reference signal-reference signal received power is measured on the configured resource elements within the considered measurement frequency bandwidth during configured measurement time opportunities.

[0067] In one embodiment of this disclosure, the first measurement is used to reflect the level of interference in the uplink channel of the user equipment.

[0068] In one embodiment of this disclosure, in a sub-band full-duplex scenario, the user equipment performs a measurement of the Layer 1 sounding reference signal received power (Layer 1-SRS-RSRP or L1-SRS-RSRP). Compared to the Layer 3 measurement performed in a non-sub-band full-duplex scenario, the measurement accuracy requirement is higher and the measurement is more accurate.

[0069] In one embodiment of this disclosure, the second measurement is a cross-link interference received signal strength indication or a layer-one cross-link interference received signal strength indication.

[0070] In one embodiment of this disclosure, the Cross Link Interference-Received Signal Strength Indicator (CLI-RSSI) can be defined as the linear average of the total received power (in W) observed across the configured measurement bandwidth of all sources, only within the configured Orthogonal Frequency Division Multiplexing (OFDM) symbols configured with the measurement time resources. The OFDM symbols are used to precisely control when measurements are performed to avoid the influence of unnecessary noise and other signals.

[0071] It should be noted that the signal source may include, but is not limited to, co-channel serving cells, co-channel non-serving cells, adjacent channel interference, thermal noise, etc., and the embodiments disclosed herein do not specifically limit this.

[0072] In one embodiment of this disclosure, in a sub-band full-duplex scenario, the user equipment performs Layer 1 cross-link interference received signal strength indication (Layer 1-CLI-RSSI or L1-CLI-RSSI) measurement. Compared with the Layer 3 measurement performed in a non-sub-band full-duplex scenario, the measurement accuracy requirement is higher and the measurement is more accurate.

[0073] In one embodiment of this disclosure, the second measurement is used to reflect the level of interference in the user equipment downlink channel.

[0074] In one embodiment of this disclosure, it further includes any one or a combination of two of the following: a first resource is a sounding reference signal resource; and a second resource is a measurement resource configured for cross-link interference received signal strength indication.

[0075] In one embodiment of this disclosure, the first resource is configured in the first information unit.

[0076] In one embodiment of this disclosure, the first information unit includes one or more of the following configuration information: first resource information, first resource carrier interval, first resource index, first resource period, bandwidth portion identifier (BWP ID), and cell index.

[0077] In one embodiment of this disclosure, the relevant configuration information elements contained in the sounding reference signal resource (SRS Resource) and the first information element (IE) are key information for assessing the uplink channel state.

[0078] In one embodiment of this disclosure, the first resource information may typically refer to the construction information of the sounding reference signal (SRS); the first resource carrier interval may typically refer to the subcarrier interval used by the SRS, thereby determining the bandwidth and time position of the SRS; the first resource index is a unique index of the SRS resource, used to distinguish different SRS resources; the first resource period may refer to the transmission period of the SRS; the BWP ID is used to indicate the BWP associated with the SRS resource; and the cell index is used to indicate the cell to which the SRS resource belongs.

[0079] In one embodiment of this disclosure, the second resource is configured in the second information unit; or the second resource is configured in one downlink subband or two downlink subbands.

[0080] In one embodiment of this disclosure, the second information unit includes one or more of the following configuration information: second resource information, second resource identifier ID, second resource subcarrier spacing, second resource start position, second resource size, second resource period, and offset.

[0081] In one embodiment of this disclosure, the relevant configuration information elements contained in the measurement resource configured for CLI-RSSI and the second information element (IE) are key information for assessing the downlink channel state.

[0082] It should be noted that the second resource may include at least any of the following: Channel State Information-Reference Signal (CSI-RS) resource, Synchronization Signal and Physical Broadcast Channel Block (SSB) resource, or Demodulation Reference Signal (DMRS) resource. In addition, the second resource may also be other available resources. The above resource types are only for illustrative purposes and are not specifically described in this disclosure.

[0083] In one embodiment of this disclosure, when a second resource is configured in a specific downlink subband, the associated configuration information defines the specific resource allocation within that subband. Furthermore, a broadband measurement report or a measurement report specific to that subband can be generated based on network requirements.

[0084] In one embodiment of this disclosure, when the second resource is distributed across two different downlink subbands, each subband requires corresponding configuration information. Furthermore, a broadband measurement report for the entire frequency band can be generated based on network requirements, or a detailed measurement report can be generated separately for each subband.

[0085] In one embodiment of this disclosure, the second resource information can typically be used to describe the specific type and purpose of the second resource, such as whether CSI-RS resources, SSB resources, or DMRS resources are used; the second resource identifier ID is a unique identifier used to distinguish different measurement resources; the second resource subcarrier spacing can refer to the subcarrier spacing used by the second resource to determine the time and frequency position of the second resource; the second resource start position is used to specify the starting position of the second resource on the time-frequency resource grid, such as the starting physical resource block (PRB) or the starting symbol; the second resource size can refer to the bandwidth and time length occupied by the second resource, such as the number of PRBs or the number of symbols; the second resource period and offset are used to determine the transmission frequency of the second resource and its time offset relative to a certain reference point to ensure regular and accurate measurements.

[0086] In one embodiment of this disclosure, the first measurement period or the first delay is related to at least one of the following: a first coefficient, a probe reference signal measurement period, and a discontinuous reception period.

[0087] In one embodiment of this disclosure, the first measurement period or the first delay may be equal to a first coefficient multiplied by the SRS measurement periodicity, or it may be equal to the first coefficient multiplied by the maximum value of the SRS measurement period and the discontinuous reception (DRX) period length. The first coefficient is a sampling coefficient, and for example, the value of the first coefficient may be 1 and / or 3.

[0088] In one embodiment of this disclosure, the first coefficient is configured by the network or based on a protocol agreement.

[0089] In one embodiment of this disclosure, the value of the first coefficient can be obtained based on network configuration or based on protocol agreement, that is, the network-side device and the user equipment agree on the corresponding value without network configuration. It should be noted that the above-mentioned value of the first coefficient is only for illustrative purposes, and this disclosure does not impose any specific limitations on it.

[0090] In one embodiment of this disclosure, the second measurement period or second delay is related to at least one of the following: a second coefficient, the period of the configured measurement resources for cross-link interference received signal strength indication, and the discontinuous reception period.

[0091] In one embodiment of this disclosure, the second measurement period or second delay may be equal to the second coefficient multiplied by the period of the configured measurement resources for cross-link interference received signal strength indication, or it may be equal to the second coefficient multiplied by the maximum value of the period of the configured measurement resources for cross-link interference received signal strength indication and the DRX period length. The second coefficient is a sampling coefficient, and for example, the value of the second coefficient may be 1 and / or 3.

[0092] In one embodiment of this disclosure, the second coefficient is configured by the network or based on a protocol agreement.

[0093] In one embodiment of this disclosure, the value of the second coefficient can be obtained based on network configuration or based on protocol agreement, that is, the network-side device and the user equipment agree on the corresponding value without network configuration. It should be noted that the above-mentioned value of the second coefficient is only for illustrative purposes, and this disclosure does not impose any specific limitations on it.

[0094] In one embodiment of this disclosure, the first measurement period or first delay, and / or the second measurement period or second delay, are related to the downlink timing of the network or user equipment.

[0095] In one embodiment of this disclosure, the first measurement period or first delay may be the period corresponding to the measurement of the first measurement quantity performed by the user equipment based on the first resource. The user equipment may refer to a terminal. The first measurement quantity is the received power of the probe reference signal, and the first resource is the probe reference signal resource. During the transmission of the probe reference signal in the uplink channel of the interfering terminal, the interfered terminal can receive and measure the probe reference signal transmitted in the uplink channel of the interfering terminal. Therefore, the first measurement period or first delay is related to the downlink timing of the interfered terminal in the serving cell. The downlink reference timing of the serving cell and the arrival time of the probe reference channel are less than or equal to a first threshold. The interfering terminal is the terminal that interferes with the interfered terminal. The serving cell is the cell that communicates with the interfering terminal (provided it belongs to the serving cell) and the interfered terminal respectively. The first threshold includes at least one of the following: propagation delay difference, cell phase error, timing advance offset, etc.

[0096] In one embodiment of this disclosure, the second measurement period or second delay is the period corresponding to the terminal performing a second measurement based on a second resource. The second measurement is a cross-link interference received signal strength indication, and the second resource is a configured measurement resource for the cross-link interference received signal strength indication. For example, the measurement resource can be transmitted in the uplink channel of the interfering terminal, or in the downlink channel of the interfering terminal and / or the interfered terminal. The interfered terminal receives and measures the measurement resource. Therefore, the second measurement period or second delay is related to the downlink time of the cell where the interfered terminal is located. The interfering terminal is the terminal that interferes with the interfered terminal. The interfered terminal may belong to the same serving cell as the interfering terminal or to a different serving cell.

[0097] In one embodiment of this disclosure, the first measurement report and / or the second measurement report are layer-one measurement reports.

[0098] In one embodiment of this disclosure, the accuracy of the layer 1 measurement report is higher than that of the layer 3 measurement report, which helps to improve measurement accuracy and obtain a more accurate measurement report.

[0099] In one embodiment of this disclosure, it further includes any one or a combination of two of the following: the first measurement report is an aperiodic report, a periodic report, or a semi-persistent report; the second measurement report is an aperiodic report, a periodic report, or a semi-persistent report.

[0100] In one embodiment of this disclosure, aperiodic reporting includes aperiodic-triggered reporting, aperiodic-triggered periodic reporting, or aperiodic-triggered semi-persistent reporting; periodic reporting includes periodic-triggered reporting; and semi-persistent reporting includes semi-persistent-triggered reporting.

[0101] In one embodiment of this disclosure, the first measurement report and / or the second measurement report meet the Layer 1 cross-link interference accuracy requirement or the Layer 1 reference signal received power accuracy requirement.

[0102] In one embodiment of this disclosure, Layer 1 cross-link interference measurement includes Layer 1 cross-link interference received signal strength indication measurement or Layer 1 reference signal received power measurement. This is the primary measurement method used in sub-band full-duplex scenarios, rather than Layer 3 measurement used in non-sub-band full-duplex scenarios. Correspondingly, the Layer 1 cross-link interference accuracy requirement or Layer 1 reference signal received power accuracy requirement is higher than the Layer 3 accuracy requirement, resulting in a more accurate cross-link interference measurement report. This helps to achieve more precise cross-link interference measurement and improve the performance of the sub-band full-duplex system.

[0103] In one embodiment of this disclosure, it further includes any one or a combination of two of the following: a first measurement report is a broadband report or a subband report; a second measurement report is a broadband report or a subband report.

[0104] In one embodiment of this disclosure, the first measurement report may be a broadband report, i.e., a measurement report of the entire bandwidth, or a report of one or more uplink subbands, i.e., a measurement report of one or more uplink subbands; the second measurement report may be a broadband report, i.e., a measurement report of the entire bandwidth, or a report of one or more downlink subbands, i.e., a measurement report of one or more downlink subbands.

[0105] In one embodiment of this disclosure, the method further includes: reporting the user equipment's ability to support cross-link interference measurements.

[0106] In one embodiment of this disclosure, prior to S102 above, the method further includes: sending a capability notification message to a network-side device via radio resource control signaling, wherein the capability notification message is used to notify the network-side device of the terminal's ability to support cross-link interference measurement, and the network-side device is a device that communicates with the terminal.

[0107] In one embodiment of this disclosure, the terminal can typically support multiple capabilities and can report to the network-side device via Radio Resource Control (RRC) signaling the terminal's ability to perform cross-link interference measurements.

[0108] In one embodiment of this disclosure, after receiving a capability notification message sent by a terminal, the network-side device typically returns a reconfiguration message to the terminal. This reconfiguration message can be an RRC reconfiguration message, which may contain multiple information elements, each corresponding to different configuration parameters. The terminal can adjust its own configuration according to the received reconfiguration message to meet measurement requirements.

[0109] Based on the same inventive concept, this disclosure also provides a user equipment cross-link interference measurement device, as shown in the following embodiment. Since the principle by which this device embodiment solves the problem is similar to that of the above method embodiment, the implementation of this device embodiment can refer to the implementation of the above method embodiment, and repeated details will not be described again.
