Description

Technical Field

[0001] This application relates to the field of wireless communication, and more particularly to an information transmission method, apparatus, related equipment, storage medium, and computer program product. Background Technology

[0002] In traditional Time Division Duplex (TDD) scenarios, a base station can only transmit downlink signals or receive uplink signals at any given time. For two adjacent cells, the uplink transmission in one cell may interfere with the downlink transmission in the other cell; this interference is known as Cross Link Interference (CLI). Adjacent base stations can exchange their planned TDD downlink or uplink time slot configurations (which can also be understood as envisioned or future uplink / downlink time slot configurations). After obtaining this time slot configuration, the base station can mitigate CLI by configuring the corresponding transmission direction in different time slots.

[0003] However, there is still no effective solution for how to solve the interference in subband full-duplex (SBFD) scenarios. Summary of the Invention

[0190] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0191] In subband full-duplex technology, different subbands can be configured with different transmission directions within a single carrier segment, thus enabling both downlink and uplink transmission opportunities at any given time, reducing latency in TDD systems. Furthermore, the increased uplink transmission resources also improve uplink coverage. For example, Figure 1 As shown, in a subband full-duplex scenario, from the base station's perspective, there is both uplink and downlink transmission within a time slot, but on a specific frequency resource, there is only uplink or downlink transmission. Since the uplink and downlink transmission directions within the subband bandwidth configured between adjacent base stations may differ, at the same time, some user equipment (UEs) within the base station's coverage area may experience interference from the same-frequency subband and / or inter-subband interference when performing downlink measurements from other UEs under adjacent base stations. For example, ... Figure 2 As shown, UE1, which performs downlink measurements under the coverage of base station 1, will be interfered with by the same frequency subband of UE2, which transmits uplink data at the same frequency as UE1 under the coverage of base station 2. At the same time, UE1 will also be interfered with by the subband of UE3, which transmits uplink data in a different subband than UE1.

[0192] In practical applications, the scheme adopted to mitigate the future uplink and downlink time slot configuration between base stations introduced by CLI may not be able to resolve the interference between UEs in the same frequency sub-band and / or between sub-bands caused by the more flexible and dynamic sub-band full-duplex configuration compared to traditional TDD. Furthermore, since multiple sub-bands of a base station may be configured with different transmission directions within a certain time domain, the disturbed base station may not be able to determine which segment or segments of the sub-bands from the disturbing base station are causing the interference to the UEs within the disturbed base station.

[0193] Based on this, in various embodiments of this application, adjacent base stations can exchange their respective sub-band full-duplex related configuration information, so that it is possible to determine whether there is interference between terminals under two base stations caused by sub-band full-duplex configuration and / or interference between sub-bands, and then adopt corresponding interference resolution strategies to improve wireless communication quality.

[0194] Specifically, embodiments of this application provide an information transmission method applied to a first network device, such as... Figure 3 As shown, the method includes:

[0195] Step 301: Send first information to the second network device, and / or receive second information sent by the second network device; the first information includes sub-band full-duplex related configuration information of the first network device, and the second information includes sub-band full-duplex related configuration information of the second network device.

[0196] The sub-band full-duplex related configuration information includes at least one of the following:

[0197] The identifier (e.g., ID) for each sub-band;

[0198] The transmission direction of each sub-band;

[0199] The cycle period of each sub-band;

[0200] Time-domain related information for each sub-band;

[0201] Frequency domain information for each sub-band.

[0202] It should be noted that, in various embodiments of this application, the information transmitted between the first network device and the second network device (such as the first information, the second information, etc.) may also be referred to as or include configuration. That is, when the first network device and the second network device transmit information to each other, the information transmission method provided in the embodiments of this application may also be understood as or referred to as a configuration interaction method.

[0203] In practical applications, the first network device may specifically include a base station, and the second network device may specifically include a base station adjacent to the base station (i.e., the first network device); in other words, the first network device and the second network device may be two adjacent network devices.

[0204] In practical applications, it can be understood that when the first network device sends the first information to the second network device, the first network device needs to support full-duplex capability; when the first network device does not support full-duplex capability, the first network device cannot send the first information to the second network device, that is, the first network device will not send the first information to the second network device.

[0205] Based on this, in one embodiment, sending the first information to the second network device may include:

[0206] If the first network device supports full-duplex capability, the first information is sent to the second network device.

[0207] In practical applications, it can be understood that when the second network device sends the second information to the first network device, the second network device needs to support full-duplex capability; when the second network device does not support full-duplex capability, the second network device cannot send the first information to the first network device, that is, the second network device will not send the second information to the first network device.

[0208] Based on this, in one embodiment, receiving the second information sent by the second network device may include:

[0209] If the second network device supports full-duplex capability, the second information sent by the second network device is received.

[0210] In practical applications, before exchanging the configuration information related to full-duplex sub-band, the first network device and the second network device can exchange information about their respective support for full-duplex capabilities, i.e., whether they support full-duplex capability. If the first network device sends information indicating that it supports full-duplex capability (which can be referred to as the third information in the following description) to the second network device, then the first network device can send the first information to the second network device; if the first network device sends information indicating that it does not support full-duplex capability (which can be referred to as the sixteenth information in the following description), then the first network device will not send the first information to the second network device. If the second network device sends information indicating that the second network device supports full-duplex capability to the first network device (which can be referred to as the fourth information in the following description), then the second network device can send the second information to the first network device, that is, the first network device can receive the second information sent by the second network device; if the second network device sends information indicating that the second network device does not support full-duplex capability to the first network device (which can be referred to as the seventeenth information in the following description), then the second network device will not send the second information to the first network device, that is, the first network device will not receive the second information sent by the second network device.

[0211] Based on this, in one embodiment, such as Figure 3 As shown, prior to step 301, the method may further include:

[0212] Step 300: Send third information to the second network device, and / or receive fourth information sent by the second network device; the third information indicates that the first network device supports full-duplex capability, and the fourth information indicates that the second network device supports full-duplex capability. In other words, the method may further include at least one of the following:

[0213] Send the third information to the second network device;

[0214] Receive the fourth information sent by the second network device.

[0215] In another embodiment, the method may further include:

[0216] Send a sixteenth message to the second network device, the sixteenth message indicating that the first network device does not support full-duplex capability; or,

[0217] The system receives a seventeenth message sent by the second network device, the seventeenth message indicating that the second network device does not support full-duplex capability.

[0218] In practical applications, as can be seen from the above description, when the sixteenth information is sent to the second network device, the first network device does not send the first information to the second network device; when the seventeenth information is received from the second network device, the first network device does not receive the second information sent by the second network device.

[0219] In one embodiment, the time-domain related information of each sub-band may include at least one of the following:

[0220] The identifier (e.g., ID) of each time-domain transmission resource;

[0221] The identifier (e.g., ID) of the first time-domain transmission resource;

[0222] The identifier (e.g., ID) of the last time-domain transmission resource;

[0223] The number of time-domain transmission resources, that is, the number of time-domain transmission resources within a sub-band, and also the number of identifiers for time-domain transmission resources within a sub-band.

[0224] The granularity of the time-domain transmission resources may include frames, subframes, time slots, or symbols, etc., and this application embodiment does not limit this.

[0225] In practical applications, the time-domain related information of each sub-band may specifically include the identifier of each time-domain transmission resource in multiple (i.e., at least two) time-domain transmission resources, as well as the number of identifiers of time-domain transmission resources within the sub-band. Alternatively, to save resources by conserving the content of signaling interactions (i.e., reducing the content of information transmitted between the first network device and the second network device (i.e., the first information and the second information)), the time-domain related information of each sub-band may only include the identifier of the first time-domain transmission resource and the identifier of the last time-domain transmission resource among multiple time-domain transmission resources, or it may only include the identifier of the first time-domain transmission resource and the number of time-domain transmission resources within the sub-band.

[0226] In one embodiment, the frequency domain related information of each sub-band may include at least one of the following:

[0227] Subband bandwidth;

[0228] The sub-band corresponds to the subcarrier spacing;

[0229] The number of RBs within the subband;

[0230] The location of CRB0 or ​​Point A within the sub-band;

[0231] The starting RB position within the sub-band.

[0232] In practical applications, this application embodiment does not limit the specific format of the time-domain related information and frequency-domain related information of each sub-band included in the sub-band full-duplex related configuration information. For example, for two adjacent base stations (i.e., the first network device and the second network device), the interaction format of the information element (IE) of a specific sub-band can be distinguished at a specific time-domain granularity, and further distinguished by the frequency domain range of different sub-bands within each time-domain granularity; or, the interaction format of the IE of a specific sub-band can be distinguished at a specific frequency domain granularity, and further distinguished by different time-domain granularities within the frequency domain granularity of each sub-band.

[0233] In practical applications, after receiving the first information, the first network device, based on the first and second information—that is, based on the sub-band full-duplex related configuration information of the first and second network devices—can identify whether a terminal of the first network device (which can be understood as a terminal under the first network device, a terminal within the coverage area of ​​the first network device, or a terminal served by the first network device, referred to as the second terminal in the following description) may be subject to interference from the same frequency sub-band and / or inter-sub-band interference from a terminal of the second network device (which can be understood as a terminal under the second network device, a terminal within the coverage area of ​​the second network device, or a terminal served by the second network device, referred to as the first terminal in the following description). In other words, the first network device can identify whether there is potential interference from the same frequency sub-band and / or inter-sub-band between the second terminal and the first terminal, which can also be understood as the first network device determining whether it needs to consider interference from the same frequency sub-band and / or inter-sub-band from the second network device.

[0234] In practical applications, the terminals (i.e., the first terminal and the second terminal) can also be referred to as UEs or users. Furthermore, when a terminal is interfered with, it can be called a disturbed terminal; when a terminal interferes with other terminals, it can be called a disturbing terminal. For example, if the second terminal is interfered with by the first terminal in the same frequency subband and / or by inter-subband interference, the second terminal can be called a disturbed terminal, and the first terminal can be called a disturbing terminal. Correspondingly, the first network device can be called a disturbed network device (e.g., a disturbed base station), and the second network device can be called a disturbing network device (e.g., a disturbing base station).

[0235] Furthermore, it should be noted that after receiving the second information, the second network device can perform similar operations to those of the first network device, namely, based on the sub-band full-duplex related configuration information of the first and second network devices, it identifies whether the first terminal may be subject to interference from the same-frequency sub-band and / or inter-sub-band interference of the second terminal. Moreover, when the second network device identifies that the first terminal may be subject to interference from the same-frequency sub-band and / or inter-sub-band interference of the second terminal, the second network device can continue to perform similar operations to those performed when the first network device identifies that the second terminal may be subject to interference from the same-frequency sub-band and / or inter-sub-band interference of the first terminal. The following embodiments of this application will provide a detailed description of the subsequent operations performed when the first network device identifies that the second terminal may be subject to interference from the same-frequency sub-band and / or inter-sub-band interference of the first terminal, and will not repeat the details of the subsequent operations performed when the second network device identifies that the first terminal may be subject to interference from the same-frequency sub-band and / or inter-sub-band interference of the second terminal.

[0236] In practical applications, if the first network device detects potential interference between the second terminal and the first terminal in the same frequency sub-band and / or between sub-bands, that is, if the first network device detects that the second terminal may be subject to interference from the first terminal in the same frequency sub-band and / or between sub-bands, the first network device may request the second network device to configure the configuration information related to the first reference signal configured by the second network device for the first terminal to perform interference measurement (i.e., configure the second terminal to perform interference measurement).

[0237] Based on this, in one embodiment, the method may further include:

[0238] Send a fifth message to the second network device, the fifth message being used to request configuration information related to the first reference signal configured by the second network device for the first terminal;

[0239] The system receives a sixth message sent by the second network device, the sixth message containing configuration information related to the first reference signal.

[0240] In practical applications, as can be seen from the above description, the first terminal may specifically include at least one terminal under the second network device, that is, the first terminal may specifically include at least one terminal within the coverage area of ​​the second network device, at least one terminal served by the second network device, or at least one terminal communicating with the second network device; the at least one terminal refers to one or more terminals, and the multiple terminals refer to at least two terminals.

[0241] In practical applications, the configuration information related to the first reference signal may specifically include (i.e., the sixth information may specifically include) the configuration information of the first reference signal or the first measurement resource corresponding to the first reference signal, such as at least one of the following: the time domain position, frequency domain position, period, and subcarrier frequency of the first reference signal or the first measurement resource. It may also include the type of the first reference signal and / or the measurement quantity corresponding to the first measurement resource. Specifically, the type of the first reference signal may include a Synchronization Signal Block (SSB), a Channel State Information-Reference Signal (CSI-RS), or a Sounding Reference Signal (SRS), etc.; the measurement quantity corresponding to the first measurement resource may include at least one of the following: RSRP, Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), and Cross Link Interference-Received Signal Strength Indication (CLI-RSSI), etc.

[0242] In practical applications, after receiving the sixth information, the first network device can configure the second terminal to measure the first reference signal at the corresponding time and frequency domain positions.

[0243] Based on this, in one embodiment, the method may further include:

[0244] Send a seventh message to the second terminal, the seventh message containing at least configuration information related to the first reference signal;

[0245] The system receives an eighth message sent by the second terminal, the eighth message containing a first measurement result obtained by the second terminal from measuring the first reference signal.

[0246] In practical applications, as can be seen from the above description, the second terminal can specifically include at least one terminal under the first network device. That is, the second terminal can specifically include at least one terminal within the coverage area of ​​the first network device, at least one terminal served by the first network device, or at least one terminal communicating with the first network device; the at least one terminal refers to one or more terminals, and the multiple terminals refer to at least two terminals. Furthermore, it can be understood that the seventh information can be used to instruct the second terminal to measure the first reference signal.

[0247] In practical applications, in order to improve the accuracy of interference measurement, when the second terminal measures the first reference signal, the first network device may not send downlink signals in the corresponding subband and may not configure uplink transmission resources in adjacent subbands.

[0248] In practical applications, after receiving the seventh information, the second terminal can measure the first reference signal at the corresponding time and frequency domain positions based on the configuration information related to the first reference signal, obtain the first measurement result, and send the eighth information to the first network device. After receiving the eighth information, the first network device can determine the ninth information based on the first measurement result, and the ninth information characterizes the interference type and / or state of the second terminal.

[0249] For example, assuming the type of the first reference signal includes SRS, and the measurement quantities corresponding to the first measurement resource include RSRP and CLI-RSSI, the second terminal can specifically measure the RSRP of the uplink SRS transmitted by one or more first terminals within the coverage area of ​​the second network device at at least one (i.e., one or more) configured time-frequency locations to obtain the SRS-RSRP value (which can be referred to as the first parameter in the following description); simultaneously, the second terminal can measure the total received power on the bandwidth of the second network device at multiple configured time-frequency locations to obtain the CLI-RSSI value (which can be referred to as the second parameter in the following description). When determining the ninth information based on the first measurement result (which may include the SRS-RSRP value and the CLI-RSSI value), the first network device can specifically determine whether the interference received by the second terminal from the first terminal is mainly dominated by interference in the same frequency subband or by interference between subbands by using the SRS-RSRP value and CLI-RSSI value measured simultaneously by the second terminal.

[0250] If the CLI-RSSI value measured by the second terminal is less than the first threshold and the SRS-RSRP value is less than the second threshold, it indicates that the second terminal is not interfered with or the interference is negligible. That is, the ninth information indicates that the second terminal is not interfered with or the interference is negligible.

[0251] If the ratio of the difference between the CLI-RSSI value and the SRS-RSRP value measured by the second terminal (which can be referred to as the third parameter in the following description) to the CLI-RSSI value is less than the third threshold value, it indicates that the interference in the same frequency sub-band measured by the second terminal is large, that is, the interference in the same frequency sub-band is dominant, and the ninth information indicates that the second terminal is interfered with by the first terminal in the same frequency sub-band of the second network device.

[0252] If the ratio of the difference between the CLI-RSSI value and the SRS-RSRP value measured by the second terminal to the CLI-RSSI value is greater than the fourth threshold, it indicates that the interference in the same frequency sub-band measured by the second terminal is relatively small, that is, the interference between sub-bands is dominant. In other words, the ninth information indicates that the second terminal is interfered with by the first terminal in the sub-band of the second network device.

[0253] If the ratio of the difference between the CLI-RSSI value and the SRS-RSRP value measured by the second terminal to the CLI-RSSI value is greater than the third threshold and less than the fourth threshold, it indicates that the second terminal is simultaneously affected by interference from the same frequency sub-band and interference between sub-bands. That is, the ninth information indicates that the second terminal is simultaneously affected by interference from the first terminal in the same frequency sub-band of the second network device and interference from the first terminal in the sub-band of the second network device.

[0254] Based on this, in one embodiment, as can be seen from the above description, the first measurement result may include a first parameter (i.e., the aforementioned SRS-RSRP value) and a second parameter (i.e., the aforementioned CLI-RSSI value), where the first parameter represents the RSRP of the first reference signal, and the second parameter represents the total received power over the bandwidth of the second network device; wherein, when the first parameter is less than a first threshold and the second parameter is less than a second threshold, the ninth information represents that the second terminal is not interfered with or the interference it receives is negligible; or, when the ratio of the third parameter to the second parameter is less than a third threshold, the ninth information represents that the second terminal is interfered with by a first terminal in the same frequency subband of the second network device, and the third parameter represents the difference between the second parameter and the first parameter; or, when the ratio of the third parameter to the second parameter is greater than a third threshold and less than a fourth threshold, the ninth information represents that the second terminal is simultaneously interfered with by a first terminal in the same frequency subband of the second network device and by a first terminal in the subband of the second network device; or, when the ratio of the third parameter to the second parameter is greater than a fourth threshold, the ninth information represents that the second terminal is interfered with by a first terminal in the subband of the second network device.

[0255] In practical applications, the specific values ​​of the first threshold, the second threshold, the third threshold, and the fourth threshold (i.e., the first threshold value, the second threshold value, the third threshold value, and the fourth threshold value) can be preset according to requirements (such as interference suppression requirements). This application embodiment does not limit this.

[0256] In practical applications, after determining the ninth information, the first network device can send the ninth information to the second network device.

[0257] Based on this, in one embodiment, the method may further include:

[0258] The ninth message is sent to the second network device.

[0259] In practical applications, the ninth information can also be understood as or referred to as an indication reason (i.e., an indication reason for interference). Specifically, when the second terminal is not interfered with or the interference it receives is negligible, that is, when the ninth information indicates that the second terminal is not interfered with or the interference it receives is negligible, the first network device can send an indication reason (i.e., the ninth information) to the second network device to indicate or explain that the second terminal is not currently interfered with or the interference it receives is negligible.

[0260] When the interference received by the second terminal is dominated by interference from the same frequency sub-band, that is, when the ninth information indicates that the second terminal is interfered with by the first terminal in the same frequency sub-band of the second network device, the first network device may send an indication reason (i.e. the ninth information) to the second network device to indicate or explain that the interference received by the second terminal mainly includes interference from the first terminal in the same frequency sub-band of the second network device.

[0261] When the interference received by the second terminal is dominated by inter-subband interference, that is, when the ninth information indicates that the second terminal is interfered with by the first terminal in the sub-band of the second network device, the first network device may send an indication reason (i.e. the ninth information) to the second network device to indicate or explain that the interference received by the second terminal mainly includes interference from the first terminal in the sub-band of the second network device.

[0262] When the second terminal is simultaneously subjected to interference from both the same frequency sub-band and inter-sub-band, that is, when the ninth information indicates that the second terminal is simultaneously subjected to interference from the first terminal in the same frequency sub-band of the second network device and interference from the first terminal in the inter-sub-band of the second network device, the first network device may send an indication reason (i.e., the ninth information) to the second network device to indicate or explain that the interference received by the second terminal comes from both the first terminal in the same frequency sub-band of the second network device and the first terminal in the inter-sub-band of the second network device.

[0263] In one embodiment, the method may further include:

[0264] Send at least one of the following to the second network device:

[0265] The identifier (e.g., ID) of the sub-band where the second terminal is located;

[0266] The time-domain location of the sub-band where the second terminal is located;

[0267] The frequency domain position of the sub-band where the second terminal is located;

[0268] The type of the first reference signal;

[0269] The first measurement result.

[0270] In practical applications, while, before, or after sending the ninth information to the second network device, the first network device may also send at least one of the following: the identifier of the sub-band where the second terminal is located, the time-domain position and frequency-domain position of the sub-band where the second terminal is located, the type of the first reference signal, and the first measurement result. Upon receiving this information, if the second terminal is interfered with by a first terminal in the same frequency sub-band of the second network device (i.e., when the ninth information indicates that the second terminal is interfered with by a first terminal in the same frequency sub-band of the second network device), or when the ninth information indicates that the second terminal is simultaneously interfered with by a first terminal in the same frequency sub-band of the second network device and by first terminals in different sub-bands of the second network device), the second network device may adjust the transmission direction or transmission state of the same frequency sub-band, for example, adjusting uplink transmission to downlink transmission, or adjusting downlink transmission to uplink transmission, or adjusting to no uplink or downlink transmission.

[0271] For example, assuming the second terminal needs to receive a Cell-Defining-SSB (CD-SSB) within a subband, to ensure the second terminal's reception of the CD-SSB, the first network device needs to send an indication message to instruct the second network device to suspend the uplink signal transmission of the first terminal in the same frequency subband within the configuration service area. This indication message may contain an indication reason (i.e., the ninth information), which may be described as the interference intensity of the same frequency subband being relatively high. After receiving this indication message, the second network device can adjust the transmission direction of the same frequency subband to downlink transmission in order not to affect the downlink reception of the second terminal.

[0272] In practical applications, while sending the second network device at least one of the following: the identifier of the sub-band where the second terminal is located, the time-domain position and frequency-domain position of the sub-band where the second terminal is located, the type of the first reference signal, and the first measurement result, or before or after sending the second network device, the first network device may also send the second network device the type of the third reference signal (such as the CD-SSB mentioned above) that the second terminal needs to receive or measure in the sub-band where it is located.

[0273] In practical applications, after the second network device adjusts the transmission direction or transmission status of the same frequency subband, it can send tenth information to the first network device. The tenth information may include the adjusted transmission direction or transmission status of the same frequency subband.

[0274] Based on this, in one embodiment, when the ninth information indicates that the second terminal is interfered with by a first terminal in the same frequency subband of the second network device, or when the ninth information indicates that the second terminal is simultaneously interfered with by a first terminal in the same frequency subband of the second network device and by a first terminal in a subband of the second network device, the method may further include:

[0275] The system receives tenth information sent by the second network device, the tenth information including the adjusted transmission direction or transmission status of the same frequency subband.

[0276] In practical applications, if the interference from the first terminal to the second terminal is dominated by inter-subband interference, that is, when the ninth information indicates that the second terminal is interfered with by the first terminal in the sub-band of the second network device, in order to determine which sub-band of the second network device's first terminal is causing the inter-subband interference to the second terminal, after receiving the ninth information, the second network device can configure the first terminals in different sub-bands to send the same uplink reference signal (which can be referred to as the second reference signal in the following description) at different times, and send configuration information related to the second reference signal to the first network device so that the first network device can configure the second terminal to perform interference measurement.

[0277] Based on this, in one embodiment, when the ninth information indicates that the second terminal is interfered with by a first terminal in a subband of the second network device, the method may further include:

[0278] The system receives eleventh information sent by the second network device, the eleventh information containing configuration information related to the second reference signal configured by the second network device for the first terminal.

[0279] In practical applications, as described above, the second reference signal can include the same uplink reference signal transmitted at different times by the second network device for the first terminal in different subbands. The configuration information related to the second reference signal can specifically include (i.e., the eleventh information can specifically include) the configuration information of the second reference signal or the second measurement resource corresponding to the second reference signal, such as the subband identifier (e.g., ID), the measurement time of the second terminal, and at least one of the time-domain position, frequency-domain position, period, and subcarrier frequency of the second reference signal or the second measurement resource. It can also include the type of the second reference signal and / or the measurement quantity corresponding to the second measurement resource. The type of the second reference signal can include SSB, CSI-RS, or SRS, etc.; the measurement quantity corresponding to the second measurement resource can include at least one of RSRP, RSRQ, SINR, and CLI-RSSI, etc.

[0280] In practical applications, after receiving the eleventh information, the first network device can configure the second terminal to measure the second reference signal at the corresponding time domain and frequency domain position at the corresponding measurement time.

[0281] Based on this, in one embodiment, the method may further include:

[0282] Send a twelfth message to the second terminal, the twelfth message containing at least configuration information related to the second reference signal;

[0283] The second terminal sends a thirteenth message, which includes a second measurement result obtained by the second terminal from measuring the second reference signal.

[0284] In practical applications, it can be understood that the twelfth information can be used to instruct the second terminal to measure the second reference signal, and the thirteenth information can include multiple second measurement results obtained by the second terminal after measuring the second reference signal of multiple scrambling sub-bands (i.e., sub-bands of the second network device), that is, multiple second measurement results obtained by the second terminal after measuring the second reference signal sent by the first terminal in different sub-bands of the second network device at different times.

[0285] Specifically, upon receiving the twelfth information, the second terminal can, based on the configuration information related to the second reference signal, measure the second reference signal transmitted by the first terminal at different times within different sub-bands of the second network device at the corresponding time and frequency domain positions at the corresponding measurement time, obtaining multiple second measurement results, and then sending the thirteenth information to the first network device. A second measurement result may include the identifier (e.g., ID) of a sub-band of the second network device, and the measured value of the second reference signal transmitted by the first terminal within that sub-band (e.g., at least one of RSRP, RSRQ, SINR, and CLI-RSSI). The multiple second measurement results can characterize the inter-sub-band interference from different sub-bands of the second network device measured by the second terminal. Upon receiving the thirteenth information, the first network device, based on the multiple second measurement results, can compare the measured values ​​of the second reference signal corresponding to the inter-sub-band interference of different sub-bands of the second network device, thereby determining which sub-band of the second network device generates the strongest inter-sub-band interference to the second terminal.

[0286] In one embodiment, the method may further include:

[0287] Send the second measurement result and / or the fourteenth information to the second network device, the fourteenth information including at least one of the following:

[0288] The identifier (e.g., ID) of the sub-band where the first terminal is located;

[0289] The time-domain location of the sub-band where the first terminal is located;

[0290] The frequency domain position of the sub-band where the first terminal is located.

[0291] In practical applications, the fourteenth information can be associated with the sub-band corresponding to the strongest inter-sub-band interference generated by the second network device on the second terminal (which can be referred to as the target sub-band in the following description); in other words, the fourteenth information can be used to indicate which sub-band of the second network device generates the strongest inter-sub-band interference on the second terminal, that is, the fourteenth information can include at least one of the identifier, time-domain location, and frequency-domain location of the target sub-band. Furthermore, it can be understood that the target sub-band can be an adjacent sub-band of the sub-band where the second terminal is located; when the first network device only sends the fourteenth information to the second network device, the fourteenth information can also include a second measurement result corresponding to the target sub-band, that is, it includes the measurement value of the second reference signal (such as RSRP, RSRQ, SINR, and CLI-RSSI, etc.) measured by the second terminal within the target sub-band.

[0292] In practical applications, after receiving the second measurement result and / or the fourteenth information, the second network device can adjust the transmission direction or transmission state of the subband where the first terminal is located. Specifically, it can adjust the transmission direction or transmission state of the target subband, such as changing uplink transmission to downlink transmission, or changing downlink transmission to uplink transmission, or changing it to not perform uplink or downlink transmission. Afterwards, the second network device can also send a fifteenth information to the first network device. The fifteenth information may include the adjusted transmission direction or transmission state of the subband where the first terminal is located, that is, the fifteenth information may include the adjusted transmission direction or transmission state of the target subband.

[0293] Based on this, in one embodiment, the method may further include:

[0294] The system receives a fifteenth message sent by the second network device, the fifteenth message containing the adjusted transmission direction or transmission status of the subband in which the first terminal is located.

[0295] Accordingly, embodiments of this application also provide an information transmission method, applied to a second network device, such as... Figure 4 As shown, the method includes:

[0296] Step 401: Receive first information sent by the first network device, and / or send second information to the first network device; the first information includes sub-band full-duplex related configuration information of the first network device, and the second information includes sub-band full-duplex related configuration information of the second network device.

[0297] The sub-band full-duplex related configuration information includes at least one of the following:

[0303] In one embodiment, receiving the first information sent by the first network device may include:

[0305] In one embodiment, sending the second information to the first network device may include:

[0306] If the second network device supports full-duplex capability, the second information is sent to the first network device.

[0308] Step 400: Receive third information sent by the first network device, and / or send fourth information to the first network device; the third information indicates that the first network device supports full-duplex capability, and the fourth information indicates that the second network device supports full-duplex capability. In other words, the method may further include at least one of the following:

[0309] Receive the third information sent by the first network device;

[0310] The fourth information is sent to the first network device.

[0311] In one embodiment, the method may further include:

[0312] The system receives a fifth message sent by the first network device, the fifth message being used to request the second network device to configure configuration information related to the first reference signal configured for the first terminal;

[0313] A sixth message is sent to the first network device, the sixth message containing configuration information related to the first reference signal.

[0314] In one embodiment, the method may further include:

[0315] The system receives a ninth message sent by the first network device, the ninth message representing the interference type and / or status of the second terminal of the first network device.

[0316] Wherein, the ninth information indicates that the second terminal is not interfered with or the interference it receives is negligible; or, the ninth information indicates that the second terminal is interfered with by the first terminal in the same frequency sub-band of the second network device; or, the ninth information indicates that the second terminal is simultaneously interfered with by the first terminal in the same frequency sub-band of the second network device and by the first terminal in the sub-band of the second network device; or, the ninth information indicates that the second terminal is interfered with by the first terminal in the sub-band of the second network device.

[0317] In one embodiment, the method may further include:

[0318] Receive at least one of the following from the first network device:

[0319] The identifier of the sub-band where the second terminal is located;

[0320] The time-domain location of the sub-band where the second terminal is located;

[0321] The frequency domain position of the sub-band where the second terminal is located;

[0322] The type of the first reference signal;

[0323] The second terminal measures the first measurement result obtained from the first reference signal.

[0324] In one embodiment, when the ninth information indicates that the second terminal is interfered with by a first terminal in the same frequency subband of the second network device, or when the ninth information indicates that the second terminal is simultaneously interfered with by a first terminal in the same frequency subband of the second network device and by a first terminal in an inter-subband interference of the second network device, the method may further include:

[0325] Adjust the transmission direction or transmission status of the same frequency subband;

[0326] Send a tenth message to the first network device, the tenth message containing the adjusted transmission direction or transmission status of the same frequency subband.

[0327] In one embodiment, when the ninth information indicates that the second terminal is interfered with by a first terminal in a subband of the second network device, the method may further include:

[0328] The eleventh message is sent to the first network device, the eleventh message containing configuration information related to the second reference signal configured by the second network device for the first terminal.

[0329] In one embodiment, the method may further include:

[0330] The system receives a second measurement result and / or fourteenth information sent by the first network device, wherein the second measurement result is obtained by the second terminal measuring the second reference signal, and the fourteenth information includes at least one of the following:

[0331] The identifier of the sub-band where the first terminal is located;

[0332] The time-domain location of the sub-band where the first terminal is located;

[0333] The frequency domain position of the sub-band where the first terminal is located.

[0334] In one embodiment, the method may further include:

[0335] Adjust the transmission direction or transmission status of the subband where the first terminal is located;

[0336] Send a fifteenth message to the first network device, the fifteenth message containing the adjusted transmission direction or transmission status of the subband in which the first terminal is located.

[0337] The information transmission method provided in this application embodiment involves a first network device sending first information to a second network device, and / or the first network device receiving second information sent by the second network device. The first information includes sub-band full-duplex related configuration information of the first network device, and the second information includes sub-band full-duplex related configuration information of the second network device. The sub-band full-duplex related configuration information includes at least one of the following: an identifier for each sub-band; a transmission direction for each sub-band; a cycle period for each sub-band; time-domain related information for each sub-band; and frequency-domain related information for each sub-band. The solution provided in this application embodiment allows adjacent base stations (i.e., the first network device and the second network device) to exchange their respective sub-band full-duplex related configuration information. This allows for subsequent determination of whether there is interference between terminals under the two base stations caused by sub-band full-duplex configuration in the same frequency sub-band and / or between sub-bands. Consequently, corresponding interference mitigation strategies can be adopted to improve wireless communication quality.

[0338] Furthermore, compared to the CLI scheme which only allows for uplink and downlink time slot configuration through interaction between base stations, this application proposes a more flexible and dynamic sub-band full-duplex configuration and reference signal configuration scheme. Adjacent base stations can exchange sub-band full-duplex configuration and reference signal (i.e., the first reference signal, the second reference signal, and the third reference signal) configurations, enabling the terminal (i.e., the second terminal) to measure the reference signals (i.e., the first reference signal and the second reference signal) from the terminal (i.e., the second network device) under the adjacent base station (i.e., the second network device). The base station (i.e., the first network device) can determine, based on the terminal's measurement results (i.e., the first measurement results), whether there is interference between itself and the terminals under the adjacent base station caused by the sub-band full-duplex configuration in the same frequency sub-band and / or between sub-bands. If interference exists, the base station can send an interference cause indication (i.e., the ninth information and the fourteenth information) to the adjacent base station, enabling the adjacent base station to adopt corresponding interference resolution strategies (such as adjusting the transmission direction or transmission state of the sub-band) to resolve the interference between the same frequency sub-band and / or between sub-bands caused by the sub-band full-duplex configuration.
