[0072] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0073] In the related art, research and analysis on the feasibility of base station SBFD have been carried out, specifically involving self-interference between base stations, interference between different sectors, interference between different site locations, sub-band interference between terminals, and adjacent frequency interference, etc.

[0074] When the terminal is in the connected state and uses the SBFD time slot (which can be expressed in English as slot), when the terminal uses the uplink sub-band for transmission, it will cause interference to the reception of the downlink sub-band; among them, the following three interference situations can be included:

[0075] 1. The serving cell (which can also be called the present cell) and the neighboring cell (which can also be called the neighboring area) use different SBFD frequency domain configurations, that is, the SBFD frequency domain configuration is flexible.

[0076] As Figure 1 shown, the SBFD frequency domain configurations of base station 1 and base station 2 are different (it can be understood that the frequency domain positions of the uplink sub-band (U) and the downlink sub-band (D) are different). For terminal 1 (which can also be called user equipment (UE, User Equipment) 1), when terminal 1 receives the SSB of the serving cell, it will be subject to inter-sub-band interference from terminal 2 (which can also be called UE2) and / or other terminals in the serving cell.

[0077] For terminal 3 (which can also be called UE3), when terminal 3 receives the SSB of the serving cell, it will be subject to co-frequency interference or inter-sub-band interference from terminal 2 and / or other terminals in the neighboring cell; among them, if the frequency domain position of the SSB of the serving cell overlaps with the uplink frequency (UL Tx) of terminal 2, it is co-frequency interference; if the frequency domain position of the SSB of the serving cell does not overlap with the uplink frequency of terminal 2, it is inter-sub-band interference.

[0078] In addition, when terminal 3 measures the SSB of the neighboring cell, it will also be subject to inter-sub-band interference from terminal 2 and / or other terminals in the neighboring cell.

[0079] 2. The serving cell and the neighboring cell use different SBFD frequency domain configurations.

[0080] As Figure 2 shown, the SBFD frequency domain configurations of base station 1 and base station 2 are different. For terminal 1, when terminal 1 receives the SSB of the serving cell, it will be subject to inter-sub-band interference from terminal 2 and / or other terminals in the serving cell.

[0081] For the terminal 4 (which can also be referred to as UE4), when the terminal 4 receives the SSB of the serving cell, it will be subject to co-frequency interference or inter-subband interference from the terminal 2 of the neighboring cell and / or other terminals; among them, if the frequency-domain position of the SSB of the serving cell overlaps with the uplink frequency of the terminal 2, it is co-frequency interference; if the frequency-domain position of the SSB of the serving cell does not overlap with the uplink frequency of the terminal 2, it is inter-subband interference.

[0082] 3. The serving cell and the neighboring cell use the same SBFD frequency-domain configuration.

[0083] As Figure 3 shown, the SBFD frequency-domain configurations of the base station 1 and the base station 2 are the same. For the terminal 1, when the terminal 1 receives the SSB of the serving cell, it will be subject to inter-subband interference from the terminal 2 of the serving cell and / or other terminals.

[0084] For the terminal 3, when the terminal 3 receives the SSB of the serving cell, it will be subject to co-frequency interference or inter-subband interference from the terminal 2 of the neighboring cell and / or other terminals; among them, if the frequency-domain position of the SSB of the serving cell overlaps with the uplink frequency of the terminal 2, it is co-frequency interference; if the frequency-domain position of the SSB of the serving cell does not overlap with the uplink frequency of the terminal 2, it is inter-subband interference.

[0085] In addition, when the terminal 3 measures the SSB of the neighboring cell, it will also be subject to inter-subband interference from the terminal 2 of the neighboring cell and / or other terminals.

[0086] In summary, in the SBFD scenario, there are both co-frequency interference between different cells and inter-subband interference (specifically including inter-subband interference between different cells and inter-subband interference within the same cell).

[0087] However, in the above scenario, there is currently no solution on how to ensure the normal operation of the terminal.

[0088] Based on this, in various embodiments of the present application, in the SBFD scenario, the base station issues an interference measurement configuration to the terminal, so that the terminal can perform measurements according to the interference measurement configuration, in order to subsequently determine the type of interference (such as co-frequency interference or inter-subband interference) and avoid interference. In this way, the normal operation of the terminal can be ensured.

[0089] An embodiment of the present application provides an information configuration method, which is applied to a network device, as Figure 4 shown, the method includes:

[0090] Step 401: When the SBFD frequency domain configuration of the serving cell is different from that of the neighboring cell and there is uplink-downlink interference between the SBFD frequency domain configuration of the serving cell and that of the neighboring cell, send a first message to the terminal, where the first message includes the measurement configuration information of the serving cell, and the measurement configuration information is used to measure the interference reference signal.

[0091] In practical applications, the terminal can be referred to as a UE or a user, etc. The embodiments of the present application do not limit the name of the terminal, as long as its functions are implemented.

[0092] In addition, the serving cell can be understood as the cell to which the terminal is currently connected, that is, the cell corresponding to the network device (specifically, it can be a base station, such as base station 1), and the neighboring cell can be understood as the cell adjacent to the serving cell, that is, the cell corresponding to other network devices (such as base station 2).

[0093] In practical applications, in step 401, when the SBFD frequency domain configuration of the serving cell is different from that of the neighboring cell and there is uplink-downlink interference, the network device can send the first message to the terminal; where the frequency domain configuration can be understood as the configuration of frequency domain resources (such as uplink subbands or downlink subbands); in other words, at the same moment, the frequency domain resources of the serving cell and the neighboring cell at the same frequency domain position are different. For example, the serving cell has an uplink subband at the first frequency domain position, and the neighboring cell has a downlink subband at the first frequency domain position; for another example, the serving cell has a downlink subband at the second frequency domain position, and the neighboring cell has an uplink subband at the second frequency domain position. In this case, there will be uplink-downlink asynchrony. At this time, the network device can send the first message to the terminal so that the terminal can perform measurements based on the first message; where the first message can be sent through Radio Resource Control (RRC) signaling. That is to say, the network device sends RRC signaling to the terminal, and the RRC signaling includes the first message. The embodiments of the present application do not limit the specific implementation process of how the network device sends the first message to the terminal.

[0094] In one embodiment, the measurement configuration information of the serving cell may include at least one of the following:

[0095] The frequency domain resources of the interference reference signal;

[0096] The time domain resources of the interference reference signal;

[0097] The frequency domain resources of the CD-SSB;

[0098] The measurement quantity of the interference reference signal.

[0099] Among them, the interference reference signal may include SRS, a reference signal for cross-link interference (CLI), such as a zero-power (ZP) channel state information reference signal (CSI-RS), etc. The embodiments of the present application do not limit the type of the interference reference signal. Correspondingly, the measurement quantity of the interference reference signal may include SRS-RSRP and / or CLI-RSSI, etc. The embodiments of the present application do not limit this.

[0100] In practical applications, since the CD-SSB may include important information such as the system information block 1 (SIB1), the network device may configure the CD-SSB on the frequency domain resources other than the frequency domain resources where the downlink subband of the serving cell overlaps with the uplink subband of the neighboring cell, so as to avoid co-frequency interference between terminals; that is to say, the frequency domain position of the CD-SSB may be configured at a position other than the position where the downlink subband of the serving cell and the uplink subband of the neighboring cell overlap in the frequency domain.

[0101] In one embodiment, the frequency domain resources of the interference reference signal satisfy at least one of the following:

[0102] The frequency domain resources of the interference reference signal are located within a first frequency domain range, and the first frequency domain range includes the frequency domain range where the first resource and the second resource overlap. The first resource includes the downlink subband of the serving cell, and the second resource includes the uplink subband of the neighboring cell;

[0103] The frequency domain resources of the interference reference signal are located within a second frequency domain range, and the second frequency domain range includes a first subset of the first resource. The first resource includes the downlink subband of the serving cell, and the downlink subband of the serving cell is divided into at least one subset by the guard bandwidth of the neighboring cell, and the at least one subset includes the first subset.

[0104] Among them, in practical applications, the downlink subband of the serving cell may be divided into at least one subset by the guard bandwidth (GB) between the subbands of the neighboring cell, where GB may specifically be the GB between the uplink subband and the downlink subband.

[0105] In addition, when the frequency domain resources of the interference reference signal are located within the second frequency domain range, the frequency domain resources of the SSB or CSI-RS of the serving cell may also be located within the second frequency domain range, that is, the interference reference signal and the measurement signal of the SSB or CSI-RS of the serving cell are located within the same subset.

[0106] Exemplarily, such asFigure 5 As shown, the SBFD frequency domain configurations of base station 1 and base station 2 are different, that is, the configurations of the uplink subbands (U) and downlink subbands (D) are different, and the downlink subbands corresponding to base station 2 are divided into two subsets, subset 1 and subset 2, by the GB between the subbands corresponding to base station 1. In this case, for terminal 3, if base station 2 transmits SSB or CSI-RS measurement signals within subset 2, the measurement quantity of the interference reference signal can be configured as SRS-RSRP, and the frequency domain position of the interference reference signal is within subset 2, so that the SRS time-frequency domain resources corresponding to the interference reference signal are a subset of the configured SRS time-frequency domain resources; and / or, base station 2 can configure the measurement quantity of the interference reference signal as CLI-RSSI, and the frequency domain position of the interference reference signal is within subset 2. For terminal 3, if base station 2 transmits SSB or CSI-RS measurement signals within subset 1, the frequency domain position of the interference reference signal can be configured within subset 1. For terminal 3, if base station 2 configures the frequency domain position of CD-SSB, the frequency domain position of CD-SSB can be configured within subset 1.

[0107] In one embodiment, the time domain resources of the interference reference signal satisfy at least one of the following:

[0108] The time domain resources of the interference reference signal belong to the first time domain resource set;

[0109] The time domain resources of the interference reference signal belong to the second subset of the first time domain resource set, and the second subset overlaps with the SRS time domain resources exclusive to each terminal of the neighboring cell; where

[0110] The first time domain resource set includes the SRS time domain resources exclusive to all terminals of the neighboring cell, and the SRS time domain resources exclusive to all terminals of the neighboring cell include periodic time domain resources or semi-persistent time domain resources.

[0111] Among them, the first time domain resource set can be understood as the union of the SRS time domain resources exclusive to all terminals of the serving cell and the neighboring cell; that is, the first time domain resource set includes the SRS time domain resources exclusive to all terminals of the serving cell and the neighboring cell for subsequent determination of whether there is interference between terminals; correspondingly, the second subset can overlap with the SRS time domain resources exclusive to any terminal of the neighboring cell and the serving cell.

[0112] Exemplarily, such as Figure 5As shown, the SBFD frequency domain configurations of base station 1 and base station 2 are different. In this case, if there are 3 UEs, namely UE1, UE2, and UE3, at the time domain positions of the SSB or CSI-RS measurement signals sent by the neighboring cell corresponding to base station 1 to the serving cell corresponding to base station 2, then base station 2 can configure the time domain resources of the interference reference signal based on the first time domain resource set (i.e., the set of SRS time domain resources exclusive to all terminals in the neighboring cell). Specifically, as Figure 6 shown, the first time domain resource set includes the SRS resources exclusive to UE1, the SRS resources exclusive to UE2, and the SRS resources exclusive to UE3. Then, as Figure 7 shown, base station 2 can configure the time domain resources of SRS-RSRP or CLI-RSSI as the first time domain resource set, or as the second subset of the first time domain resource set, based on the SRS time domain pattern of the neighboring cell.

[0113] In actual application, the network device can also send a trigger event to the terminal to inform the terminal how to report the measurement result.

[0114] Based on this, in one embodiment, the method may further include:

[0115] Sending fourth information to the terminal, the fourth information includes a measurement reporting trigger event for layer 1; the measurement reporting trigger event includes at least one of the following:

[0116] The frequency domain resources of the interference reference signal are within a third frequency domain range, and the third frequency domain range includes the frequency domain range of the uplink subbands of the neighboring cell;

[0117] The first measurement quantity of the interference reference signal is less than a first threshold, and the second measurement quantity of the interference reference signal is less than a second threshold;

[0118] The first measurement quantity of the interference reference signal is less than a first threshold, and the third measurement quantity of the interference reference signal is greater than a third threshold; where

[0119] The first measurement quantity includes RSRP, the second measurement quantity includes RSRQ, and the third measurement quantity includes RSSI.

[0120] Among them, the frequency domain resources of the interference reference signal being within the third frequency domain range can be understood as the frequency domain configuration condition for inter-terminal interference (such as inter-subband interference, co-frequency interference, etc.) between the serving cell and at least one neighboring cell, that is, the downlink frequency domain resources of the interference reference signal of the serving cell are within the frequency domain range of the uplink subbands of the neighboring cell.

[0121] The first measurement quantity includes the RSRP difference of the interference reference signal continuously measured by the serving cell, such as the maximum difference. In addition, the values of the first threshold, the second threshold, and the third threshold can be set as needed, and the embodiments of the present application do not limit this.

[0122] In practical applications, the network device may send the fourth information to the terminal, so that when the terminal satisfies the measurement reporting trigger event, it can report the measurement result to determine whether there is inter-subband interference between different cells; among them, the fourth information can be sent through RRC signaling, that is, the network device sends RRC signaling to the terminal, and the RRC signaling includes the fourth information. The embodiments of the present application do not limit the specific implementation process of how the network device sends the fourth information to the terminal. For co-channel interference, relevant CLI trigger events can be reused; that is, the network device can send CLI trigger events to the terminal, so that when the terminal satisfies the CLI trigger event, it can report the measurement result to determine whether there is co-channel interference.

[0123] In practical applications, after the terminal completes the measurement, it can report the measurement result to the network device.

[0124] Based on this, in one embodiment, as Figure 4 shown, the method may further include:

[0125] Step 402: Receive the second information sent by the terminal, where the second information includes the measurement result of the serving cell;

[0126] Step 403: Use the second information to determine the third information, where the third information characterizes the interference relationship of the terminal.

[0127] Among them, the measurement result may include the measurement quantity of the interference reference signal, such as SRS-RSRP or CLI-RSSI.

[0128] Here, since different interference types correspond to different interference avoidance methods, the network device can judge the reason for the change in signal quality, that is, determine the type of interference, so as to avoid interference through methods such as base station scheduling or coordination between base stations in the future, and thus ensure the normal operation of the terminal.

[0129] In actual application, the network device may determine the interference relationship of the terminal based on the measurement result. Specifically, when the quality of the interference reference signal changes, the network device may determine whether the change in the quality of the interference reference signal is associated with the interference between terminals based on the measurement result. Additionally, when it is determined that there is an association with the interference between terminals, the network device may further determine the interference relationship of the terminal, which may specifically include the interference type and the terminal associated with the interference (also referred to as the interfering terminal).

[0130] Exemplarily, if the measurement result includes SRS-RSRP and SRS-RSRP is greater than a preset threshold, the network device may determine that there is inter-subband interference in the same cell; if the measurement result includes CLI-RSSI, the network device may determine that there is inter-subband interference in the same cell and inter-subband interference between different cells, or there is inter-subband interference in the same cell; if the measurement result includes SRS-RSRP and CLI-RSSI, and the difference between SRS-RSRP and CLI-RSSI is greater than or equal to a preset threshold, the network device may determine that there is inter-subband interference in the same cell and inter-subband interference between different cells; if the measurement result includes SRS-RSRP and CLI-RSSI, and the difference between SRS-RSRP and CLI-RSSI is less than a preset threshold, the network device may determine that there is inter-subband interference in the same cell. At the same time, by matching the time corresponding to the determined interference with the SRS time-domain resources exclusive to all terminals in the neighboring cell, the network device can determine the terminal associated with the interference; that is, the network device can determine that the interference comes from the terminal corresponding to the SRS time-domain resources exclusive to the matching terminal.

[0131] Here, in actual application, for the interference relationship of the terminal, the network device may adopt an interference avoidance method to avoid interference.

[0132] Based on this, in one embodiment, the method may further include:

[0133] Perform interference coordination processing and / or interference scheduling processing based on the third information.

[0134] In actual application, the network device may perform interference coordination processing based on the third information; the network device may also perform interference scheduling processing based on the third information; the network device may further perform interference coordination processing and interference scheduling processing between network devices based on the third information; among them, the interference coordination processing may be interference coordination processing between network devices, and the interference scheduling processing may include silencing the interfering terminal, or scheduling the interfering terminal to a frequency domain resource far from the terminal, or staggering the uplink and downlink transmission times of the interfering terminal and the terminal to avoid interference. The embodiments of the present application do not limit the specific manners of the interference coordination processing and the interference scheduling processing.

[0135] Correspondingly, an information configuration method provided by an embodiment of the present application is applied to a terminal, as Figure 8 shown, and the method includes:

[0136] Step 801: When the SBFD frequency domain configuration of the serving cell is different from the SBFD frequency domain configuration of the neighboring cell, and there is uplink and downlink interference between the SBFD frequency domain configuration of the serving cell and the SBFD frequency domain configuration of the neighboring cell, receive first information sent by a network device, where the first information includes measurement configuration information of the serving cell, and the measurement configuration information is used to measure interference reference signals.

[0137] In actual application, after receiving the first information, the terminal may perform measurements based on the first information.

[0138] Based on this, in an embodiment, as Figure 8 shown, the method may further include:

[0139] Step 802: Use the first information to perform measurements to obtain second information, where the second information includes measurement results of the serving cell;

[0140] Step 803: Send the second information to the network device.

[0141] Here, the terminal may also receive fourth information sent by the network device to know how to report measurement results.

[0142] Based on this, in an embodiment, the method may further include:

[0143] Receive fourth information sent by the network device, where the fourth information includes a measurement reporting trigger event for layer 1; the measurement reporting trigger event includes at least one of the following:

[0144] The frequency domain resource of the interference reference signal is within a third frequency domain range, and the third frequency domain range includes the frequency domain range of the uplink sub-band of the neighboring cell;

[0145] The first measurement quantity of the interference reference signal is less than the first threshold, and the second measurement quantity of the interference reference signal is less than the second threshold;

[0147] When the measurement reporting trigger event is satisfied, send the second information to the network device.

[0148] In actual application, during the process of the terminal performing layer 3 (which can be expressed in English as layer 3) measurement, there may be interference between terminals (which can be understood as the interference of the neighboring cell to the serving cell); since this kind of interference can be avoided through interference coordination processing between network devices and this kind of interference occurs randomly, so, in this case, the terminal can discard the measurement result obtained by the current measurement; that is to say, the measurement result will not be used for layer 3 measurement.

[0149] Based on this, in an embodiment, the method may further include:

[0150] When performing layer 3 measurement, when the first condition is satisfied, do not report the measurement result, where the first condition includes at least one of the following:

[0151] The SBFD frequency domain configuration of the serving cell is different from the SBFD frequency domain configuration of the neighboring cell, and there is uplink-downlink interference between the SBFD frequency domain configuration of the serving cell and the SBFD frequency domain configuration of the neighboring cell;

[0152] The fourth measurement quantity of the interference reference signal is greater than the fourth threshold, and the fifth measurement quantity of the interference reference signal is less than the fifth threshold;

[0157] Wherein, in actual application, the values of the fourth threshold, the fifth threshold, the sixth threshold, the seventh threshold, the eighth threshold, and the ninth threshold can be set as needed, and the embodiments of the present application do not limit this.

[0158] Exemplarily, assuming that the interference reference signal is used for cell measurement, if the RSRP of the interference reference signal is greater than the fourth threshold and the RSRQ is less than the fifth threshold, the interference reference signal cannot be used to obtain the measurement result of the cell, that is, the terminal cannot perform measurement through the interference reference signal to obtain the measurement result of the cell.

[0159] Exemplarily, assuming that the interference reference signal is used for interference reference signal measurement, if the RSRP of the interference reference signal is greater than the seventh threshold and the SRS-RSRP within the first subset is greater than the eighth threshold, the interference reference signal cannot be used for layer 3 filtering and measurement reporting, that is, the terminal cannot perform layer 3 filtering through the interference reference signal and cannot report the measurement result to the network device.
