Communication method and communication device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on February 2, 2024, with application number 202410161599.0 and application name “Communication Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method and a communication device. Background Art

[0003] During the radio resource management (RRM) measurement process, the terminal device can measure the signals sent by the network device at different time units, such as the channel state information reference signal (CSI-RS) or the synchronization signal physical broadcast channel block (SSB), to obtain the physical layer measurement results at each time unit, and filter the physical layer measurement results to obtain filtered measurement results. The terminal device can report the filtered measurement results to the network device to determine whether the terminal device needs to switch cells. Alternatively, the terminal device can determine whether to select a cell or reselect a cell based on the filtered measurement results. In the above scheme, the process of filtering the physical layer measurement results is to merge and filter all reported physical layer measurement results.

[0004] In this solution, in a sub-band full-duplex scenario, since the interference differences in different time units are large, the channel quality differences in different time units are large. Therefore, the filtering solution in the above RRM measurement will limit the application scenarios of the RRM measurement solution. Summary of the Invention

[0005] The embodiments of the present application provide a communication method and a communication device that can be applied to more scenarios.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, a communication method is provided. The communication method includes: a terminal device receives radio resource management RRM measurement configuration information. The RRM measurement configuration information is used to indicate the first type of filtering processing and / or the second type of filtering processing. There is a correspondence between the first type of filtering processing and the sub-band full-duplex time unit, and there is a correspondence between the second type of filtering processing and the non-sub-band full-duplex time unit. The first type of filtering processing is to filter the physical layer measurement results on the sub-band full-duplex time unit, and the second type of filtering processing is to filter the physical layer measurement results on the non-sub-band full-duplex time unit. The terminal device performs the first type of filtering processing and / or the second type of filtering processing according to the RRM measurement configuration information.

[0008] Based on the communication method provided in the first aspect, the terminal device can perform filtering processing according to the RRM measurement configuration information. Since the RRM measurement configuration information indicates different types of time units, such as the physical layer measurement results on the sub-band full-duplex time unit and the non-sub-band full-duplex time unit, each adopts a filtering processing method, such as the above-mentioned first type of filtering processing and the second type of filtering processing. Therefore, the terminal device can perform filtering processing on the physical layer measurement results on different types of time units separately according to the filtering processing method corresponding to each type of time unit, which can make RRM measurement and reporting more flexible and applicable to more scenarios.

[0009] It should be understood that, unless otherwise specified, the "terminal device" in this application may refer to the terminal device itself, or to a component in the terminal device (for example, a processor, chip or chip system, etc.), or it may be a logical module or software that can implement all or part of the functions of the terminal device.

[0010] In addition, by filtering the physical layer measurement results on different types of time units separately according to the filtering processing method corresponding to each type of time unit, mutual influence between the filtering results on different time units can be avoided, thereby improving the accuracy of the RRM measurement results.

[0011] In one possible implementation, the RRM measurement configuration information includes first RRM measurement configuration information. The first RRM measurement configuration information is associated with a physical layer measurement result on a sub-band full-duplex time unit. This allows the terminal device to perform separate filtering on the physical layer measurement result on the sub-band full-duplex time unit.

[0012] In one possible implementation, the terminal device performs the first type of filtering and / or the second type of filtering based on the RRM measurement configuration information, including: performing the first type of filtering on the physical layer measurement results of the sub-band full-duplex time unit in at least one time unit based on the first RRM measurement configuration information to obtain the first type of measurement results. In this way, the physical layer measurement results of the sub-band full-duplex time unit can be filtered separately.

[0013] In one possible implementation, the first RRM measurement configuration information is associated with a first measurement result corresponding to a first measurement quantity, where the first measurement result is obtained by performing a first type of filtering on a physical layer measurement result corresponding to the first measurement quantity in at least one sub-band full-duplex time unit. The first measurement result belongs to the first type of measurement result. Thus, by configuring a measurement quantity, such as the first measurement quantity described above, on a network device, a terminal device can perform filtering based on the measurement quantity configured by the network device, thereby improving the flexibility of RRM measurements.

[0014] In one possible implementation, the communication method provided in the first aspect may further include: the terminal device sending the first type of measurement results, or performing cell selection or reselection based on the first type of measurement results. The terminal device sending the first type of measurement results enables the network device to obtain RRM measurement results for cell handover, thereby improving service continuity for the terminal device. The terminal device performing cell selection and / or reselection based on the first type of measurement results can improve service continuity for the terminal device.

[0015] In one possible implementation, the RRM measurement configuration information includes second RRM measurement configuration information, wherein the second RRM measurement configuration information is associated with physical layer measurement results for non-subband full-duplex time units. This allows the terminal device to perform separate filtering on the physical layer measurement results for non-subband full-duplex time units.

[0016] In one possible implementation, the terminal device performs the first type of filtering and / or the second type of filtering based on the RRM measurement configuration information, including: performing the second type of filtering on the physical layer measurement results of non-subband full-duplex time units in at least one time unit based on the second RRM measurement configuration information, i.e., filtering the physical layer measurement results of the non-subband full-duplex time units separately to obtain the second type of measurement results. In this way, the physical layer measurement results of the non-subband full-duplex time units can be filtered separately.

[0017] In one possible implementation, the second RRM measurement configuration information is associated with a second measurement result corresponding to the second measurement quantity. The second measurement result is obtained by performing second-type filtering on the physical layer measurement result corresponding to the second measurement quantity in a non-subband full-duplex time unit in at least one time unit. The second measurement result belongs to the second type of measurement result. Thus, by configuring a measurement quantity, such as the aforementioned second measurement quantity, on a network device, a terminal device can perform filtering based on the measurement quantity configured by the network device, thereby improving the flexibility of RRM measurements.

[0018] In one possible implementation, the communication method provided in the first aspect may further include: the terminal device sending a second type of measurement result, or performing cell selection or reselection based on the second type of measurement result. The terminal device sending the second type of measurement result enables the network device to obtain the RRM measurement result for cell handover, thereby improving service continuity for the terminal device. The terminal device performing cell selection and / or reselection based on the second type of measurement result can improve service continuity for the terminal device.

[0019] In one possible implementation, the RRM measurement configuration information includes third RRM measurement configuration information. The third RRM measurement configuration information is associated with physical layer measurement results over sub-band full-duplex time units, and associated with physical layer measurement results over sub-band full-duplex time units. This reduces the amount of RRM measurement configuration information and reduces resource overhead.

And, the terminal device performs the second type of filtering on the physical layer measurement results on the non-sub-band full-duplex time unit in multiple time units according to the third RRM measurement configuration information to obtain the second type of measurement results. In this way, the terminal device can separately filter the physical layer measurement results on the sub-band full-duplex time unit and separately filter the physical layer measurement results on the non-sub-band full-duplex time unit.

[0021] In one possible implementation, the third RRM measurement configuration information associates a first measurement result corresponding to the first measurement quantity with a second measurement result corresponding to the second measurement quantity, wherein the first measurement result is obtained by performing a first type of filtering processing on the physical layer measurement result corresponding to the first measurement quantity on a sub-band full-duplex time unit in multiple time units. The second measurement result is obtained by performing a second type of filtering processing on the physical layer measurement result corresponding to the second measurement quantity on a non-sub-band full-duplex time unit in multiple time units. The first measurement result belongs to the first type of measurement result, and the second measurement result belongs to the second type of measurement result. In this way, by configuring measurement quantities, such as the first measurement quantity and the second measurement quantity mentioned above, through the network device, the terminal device can perform filtering processing according to the measurement quantities configured by the network device, thereby improving the flexibility of RRM measurement.

[0022] In one possible implementation, the third RRM measurement configuration information includes information indicating a first filter coefficient and a second filter coefficient, where the first filter coefficient is used to obtain the first measurement result and the second filter coefficient is used to obtain the second measurement result. In this way, the filter coefficients can be configured by the network device, making RRM measurements more flexible.

[0023] In one possible implementation, the communication method provided in the first aspect may further include: the terminal device sending the first type of measurement results and / or the second type of measurement results. In this way, the network device can obtain the RRM measurement results for use in cell switching, thereby improving service continuity of the terminal device.

The first type of filtering process corresponds to a sub-band full-duplex time unit, and the second type of filtering process corresponds to a non-sub-band full-duplex time unit. The first type of filtering process is filtering the physical layer measurement results on the sub-band full-duplex time unit, and the second type of filtering process is filtering the physical layer measurement results on the non-sub-band full-duplex time unit. The network device sends the RRM measurement configuration information.

[0028] Based on the communication method provided in the second aspect, the network device can generate and send RRM measurement configuration information. Since the RRM measurement configuration information indicates different types of time units, such as the physical layer measurement results on the sub-band full-duplex time unit and the non-sub-band full-duplex time unit, each adopts a filtering processing method, such as the above-mentioned first type of filtering processing and the second type of filtering processing. In this way, the terminal device can filter the physical layer measurement results on different types of time units according to the corresponding filtering processing method of each type of time unit, which can make RRM measurement and reporting more flexible and applicable to more scenarios.

Time unit: A time unit may include one or more time slots, or one or more time domain symbols, such as orthogonal frequency division multiplexing (OFDM) symbols, or one or more mini slots, or one or more frames (also called system frames), or one or more subframes. The time length of a time slot is different under different subcarrier spacing (SCS). The larger the subcarrier spacing, the smaller the time length of the time slot; the smaller the subcarrier spacing, the longer the time length of the time slot. Similarly, the time length of a time domain symbol is different under different SCS. The larger the subcarrier spacing, the smaller the time length of the time domain symbol; the smaller the subcarrier spacing, the longer the time length of the time domain symbol. Similarly, the time length of a mini slot is different under different SCS, the time length of a system frame is different, and the time length of a subframe is different. For ease of understanding, in the following embodiments, an example is given in which a time unit includes a time domain symbol, and subsequent time domain symbols are referred to as symbols and will not be repeated.

Another example is an uplink time unit can be an uplink time slot. It should be understood that the frequency domain resources in an uplink time unit are frequency domain resources used for uplink transmission. In other words, an uplink time unit is used for uplink transmission. The link in an uplink time unit is the uplink (UL).

[0096] 3. Downlink time unit: A time unit used for downlink transmission. Symbols in a downlink time unit are all downlink symbols. For example, a downlink time unit can be a downlink symbol. Another example is a downlink time unit can be a downlink time slot. It should be understood that the frequency domain resources in a downlink time unit are frequency domain resources used for downlink transmission. In other words, a downlink time unit is used for downlink transmission. The link in a downlink time unit is called a downlink (DL).

[0097] 4. Flexible time unit: A time unit that can be used for both uplink and downlink transmissions. Symbols in a flexible time unit are flexible symbols. For example, a flexible time unit can be a flexible symbol.

[0098] 5. A subband may be a frequency band that includes some of the activated frequency domain resources. A subband that includes frequency domain resources used for uplink transmission is called an uplink subband, and a subband that includes frequency domain resources used for downlink transmission is called a downlink subband. The link on the uplink subband may be called an uplink (UL), and the link on the downlink subband may be called a downlink (DL).

[0099] 6. Subband full-duplex (SBFD) solution: In a time division duplexing (TDD) system, DL usually occupies the main time domain resources. As shown in Figure 1, taking one carrier and the time unit including time unit 1 to time unit 5 as an example, the links on time unit 1 to time unit 4 are all DL, and the link on time unit 5 is UL. It can be seen that the coverage between DL and UL is unbalanced. Compared with the frequency division duplexing (FDD) system, the TDD system has fewer uplink resources and a longer uplink transmission delay. To address the uplink coverage and delay issues in the TDD system, the SBFD (subband full duplex, SBFD) solution was proposed in the 3rd Generation Partnership Project (3GPP) Technical Specification 18 (release 18, R18). In an SBFD scheme, for a carrier, at least one time unit can be configured with multiple subbands, and the transmission directions of different subbands can be different. In other words, the multiple subbands in at least one time unit can include at least one uplink subband and at least one downlink subband, or the links in at least one time unit can include both uplink and downlink. Taking the example of time units including time units 1 through 5, as shown in Figure 2(a), some possible SBFD schemes are as follows: for a carrier, the link in time unit 1 is DL, and each of time units 2 through 4 is configured with three subbands, one of which is UL, and the other two are DL. The link in time unit 5 is UL. For another example, as shown in Figure 2(b), for a carrier, the link in time unit 1 is DL, and each of time units 2 through 4 can be configured with two subbands, one of which is UL and the other is DL. The link in time unit 5 can be UL.

[0100] 7. SBFD time unit, or SBFD time unit: refers to a time unit configured using the SBFD scheme, or a time unit configured with an SBFD operation. For example, an SBFD time unit is a time unit configured with both an uplink subband and a downlink subband in the frequency domain. An SBFD time unit can be used for both uplink transmission (on the uplink subband) and downlink transmission (on the downlink subband) at the same time. An SBFD time unit can be a time slot, in which case all symbols in the SBFD time unit are SBFD symbols. In other words, the SBFD operation is configured according to the time slot. Alternatively, the SBFD time unit can include one or more SBFD symbols, or in other words, the SBFD operation is configured according to the symbol.

[0101] 8. Non-SBFD time units are time units that are not configured for SBFD operation. In downlink measurements, where the signal to be measured (also called a measurement reference signal) is a downlink signal, non-SBFD time units may include downlink time units and / or flexible time units. Alternatively, flexible time units may be non-SBFD time units, and / or downlink time units may be non-SBFD time units.

[0102] In uplink measurements, i.e., when the measurement reference signal is an uplink signal, the non-SBFD time unit may include an uplink time unit and / or a flexible time unit; in other words, the flexible time unit is a non-SBFD time unit, and / or the uplink time unit is a non-SBFD time unit. The following embodiments are all illustrated with downlink measurements as examples and will not be further described.

[0103] The number of symbols in the non-SBFD time unit is the same as the number of symbols in the SBFD time unit.

[0104] It should be understood that, unless otherwise specified, the time units in the following embodiments are all for the same frequency domain range, such as time domain resources within a bandwidth part (BWP) or time domain resources within a carrier, and will not be further elaborated.

[0105] It should be understood that SBFD time units and non-SBFD time units are different types of time units.

[0106] 9. Radio resource management (RRM) measurement is a technology that can be used to measure the signal quality (also called communication quality) of a terminal device to the serving cell (cell) of the terminal device and / or the cells adjacent to the serving cell. A technology that a terminal device can use to manage cells based on the measured signal quality. For example, in order to improve the service continuity of a terminal device, when the terminal device is in a connected state, the terminal device can switch cells based on the measured signal quality. When the terminal device is in an idle state, the terminal device can select or reselect a cell based on the measured signal quality. When the terminal device is in an inactive state, the terminal device can select or reselect a cell based on the measured signal quality. It should be understood that the connected state can also be called a radio resource control (RRC) connected state, the idle state can also be called an RRC idle state, and the inactive state can also be called an RRC inactive state.

[0107] RRM measurements may also be referred to by other names, such as signal quality measurement, channel quality measurement, etc. RRM measurements may also be referred to as layer 3 (L3) measurements or higher-layer measurements. RRM measurement configuration information may also be referred to by other names, such as measurement configuration information, measurement configuration, etc.

[0108] For ease of understanding, the following describes the RRM measurement process using an example of a terminal device in a connected state. FIG3 is a schematic diagram of the RRM measurement process. As shown in FIG3 , the RRM measurement includes the following steps S301 to S303 :

[0109] S301: A network device sends RRM measurement configuration information. Correspondingly, a terminal device receives the RRM measurement configuration information.

[0110] RRM measurement configuration information is information used to perform RRM measurement (measurement configuration). Multiple RRM measurement configuration information can be configured on a terminal device. In some examples, the terminal device can perform RRM measurement based on the RRM measurement configuration information. Among them, the RRM measurement configuration information is configuration information used to implement RRM measurement. The RRM measurement configuration information can be configured with an identifier of the RRM measurement information, such as a measurement identification. In addition, the RRM measurement configuration information can be associated with (or correspond to, or be configured with) a measurement target (measurement object) and a reporting configuration (reporting configuration), and the RRM measurement configuration information on the terminal device can be configured by the network device. Among them, the measurement target includes information such as measurement reference signal, measurement amount, SSB measurement time configuration (measurement timing configuration, SMTC). The reporting configuration includes criteria (or conditions) for triggering the reporting of measurement results of RRM measurement, such as periodic reporting and event-triggered reporting. Among them, for periodic reporting, the reporting configuration includes information for indicating the reporting interval, the number of reports, and the measurement reporting amount. For event-triggered reporting, the reporting configuration includes information indicating the events that trigger reporting (such as event A1, event A2, event A3, event A4, event A5, event A6, etc.), the measurement reporting trigger amount, and the trigger threshold (also referred to as the trigger threshold value) corresponding to each measurement reporting trigger amount. For example, for reference signal received power (RSRP) RSRP, the trigger threshold is 100 milliwatt decibels (milliwatt decibel, dBm), and for reference signal received quality (RSRQ), or signal interference noise ratio (SINR), the trigger threshold is 60dBm. It should be understood that the trigger threshold here is only for example. In actual implementation, the trigger threshold can be determined according to the specific measurement amount and scenario, which will not be repeated here.

[0111] The measurement target may also include a layer 3 (L3) filter coefficient corresponding to the measurement quantity in the measurement target. The L3 filter coefficient may also be referred to as a high-layer filter coefficient, an L3 filter parameter, a high-layer filter parameter, an L3 filter factor, or a high-layer filter factor.

[0112] The measurement quantity in the above measurement target is a measurement indicator. For example, the measurement quantity may be one or more of the following: RSRP, RSRQ, SINR, or received signal strength indication (RSSI).

[0113] The above-mentioned SSB can also be called synchronization channel and broadcast channel block.

[0114] The above-mentioned measurement reporting amount, that is, the reported indicator, is at least one of the measurement amounts indicated in the measurement target.

[0115] The measurement reporting trigger quantity is an indicator that triggers reporting of the measurement reporting quantity. The measurement reporting trigger quantity is at least one of the measurement quantities indicated in the measurement target.

[0116] S302: The terminal device performs RRM measurement according to the RRM measurement configuration information to obtain an RRM measurement result.

[0117] In S302 above, the RRM measurement result is a measurement result after combining and filtering the physical layer measurement result. The terminal device measures a measurement reference signal, such as a channel state information-reference signal (CSI-RS) or SSB, to obtain a physical layer measurement result, and filters the physical layer measurement result based on a filter coefficient to obtain a filtered measurement result, i.e., the RRM measurement result.

[0118] It should be understood that the cells for performing RRM measurement can be one or more, such as the serving cell of the terminal device and the neighboring cells of the serving cell of the terminal device. RRM measurement of the neighboring cells of the serving cell of the terminal device is hereinafter referred to as neighboring cell measurement.

[0119] For example, if the terminal device is in an idle state and the S-Measure criterion is configured in the RRM measurement configuration information, the terminal device can determine whether it is necessary to perform neighboring cell measurement based on the S-Measurement criterion, where the neighboring cell measurement includes same-frequency neighboring cell measurement, different-frequency neighboring cell measurement, and inter-radio access technology (Inter-RAT) measurement.

[0120] S303: The terminal device sends the RRM measurement result. Correspondingly, the network device receives the RRM measurement result.

[0121] That is, the terminal device reports the RRM measurement result. It should be understood that the RRM measurement result reported by the terminal device can be used to determine whether the terminal device performs cell handover. In other words, the network device can determine whether the terminal device performs cell handover based on the RRM measurement result.

[0122] When the terminal device is in an idle state or an inactive state, the RRM measurement process may include S301 and S302 in Figure 3 above. In addition, the terminal device may also perform cell selection or cell reselection based on the measurement result in S302.

[0123] In some scenarios, in the RRM measurement configuration information of the terminal device, the filter coefficients are configured together for the SBFD time unit and the non-SBFD time unit. That is, the physical layer measurement results corresponding to the same measurement quantity in the SBFD time unit and the non-SBFD time unit are combined and filtered using the same filter coefficient, and the measurement results after each filtering process are related to the measurement results after filtering that have been obtained before the filtering process. In other words, in the scenario including the physical layer measurement results of the SBFD time unit and the non-SBFD time unit, the measurement result obtained after the n-th filtering process satisfies the relationship shown in the following formula (1), or the measurement result obtained after the n-th filtering process is obtained according to the following formula (1), or the n-th filtering process is performed according to the following formula (1): F n = (1–a)*F n-1 +a*M n ; (1)

[0124] Among them, F n is the measurement result after the nth filtering process, and n is an integer. For example, n is a positive integer greater than or equal to 1. a is the filtering coefficient, a = 1 / 2 (k / 4) , k is a parameter configured by the network device. In some examples, k can be configured by high-level parameters such as filter efficiency (filterConfficient). n-1 is the measurement result after the n-1th filtering, M n For the first filtering process, that is, when the first physical layer measurement result is received, F0=M1.

[0125] It should be understood that in the embodiments of the present application, the nth filtering process refers to the nth filtering process performed on the physical layer measurement result, and performing the nth filtering process refers to performing the nth filtering process on the physical layer measurement result, or in other words, performing the filtering process on the nth physical layer measurement result. The physical layer measurement result of each filtering process may be different. For example, in the nth filtering process, the physical layer measurement result that is filtered may be the most recent physical layer measurement result before the nth filtering process is performed.

[0126] Note that in the embodiment of the present application, the physical layer measurement result may also be referred to as a measurement result from the physical layer.

[0127] The following further illustrates the principle of RRM measurement in combination with specific physical layer measurement results and the above formula (1).

[0128] As shown below, assuming that the physical layer measurement results are X1, X2, X3, and X4 in sequence, where X1 is the physical layer measurement result on a non-SBFD time unit, and X2, X3, and X4 are all physical layer measurement results on a SBFD time unit, assuming that the physical layer measurement result after the first filtering process is M1, M1 = X1, the physical layer measurement result after the second filtering process is M2, M2 = X2, the physical layer measurement result after the third filtering process is M3, M3 = X3, and the physical layer measurement result after the fourth filtering process is M4, M4 = X4. Then, the measurement results after the first filtering process satisfy the relationship shown in the following formula (2): F1 = (1–a)*F0-1 + a*M1 = (1–a)*M1 + a*M1; (2)

[0129] The measurement result after the second filtering satisfies the relationship shown in the following formula (3): F2=(1–a)*F1+a*M2; (3)

[0130] The measurement result after the third filtering satisfies the relationship shown in the following formula (4): F3=(1–a)*F2+a*M3; (4)

[0131] The measurement result after the fourth filtering satisfies the relationship shown in the following formula (5): F4=(1–a)*F3+a*M4; (5)

[0132] In this way, the RRM measurement result can be obtained, that is, the measurement result F4 after filtering X1, X2, X3 and X4. It can be seen that the measurement result after the fourth filtering is correlated with the measurement results after the first filtering to the third filtering.

[0133] Assume that the time units include time units 1 to time units 5, where the physical layer measurement results of time units 1 to time units 4 are as follows: time unit 1 is a non-SBFD time unit, time units 2 and time units 4 are both SBFD time units, time unit 5 is an uplink time unit, and the physical layer measurement results of time units 1 to time units 4 correspond to X1, X2, X3, and X4, respectively. The relationship between each time unit, each filtering result, and the filtering coefficient is shown in Figure 4.

[0134] Furthermore, for SBFD time units, since different subbands, such as uplink and downlink subbands, exist within the same time unit, signal energy within a subband can leak into other adjacent subbands (adjacent in frequency). This means that energy leakage occurs between the uplink and downlink, leading to interference between the uplink and downlink, known as cross-link interference (CLI). This is explained below with reference to time units 1 through 5. As shown in Figure 4, the link in time unit 1 is the uplink, the links in time units 2 through 4 include both uplink and downlink, and the link in time unit 5 is the uplink. Specifically, CLI exists between the uplink and downlink in time units 2 through 4.

[0135] Among them, according to the source of interference, cross-link interference includes two major categories. The first type of cross-link interference is cross-link interference between two terminal devices, including one or more of the following: (1) The uplink signal sent by a terminal device within the coverage of a cell interferes with the downlink signal received by another terminal device within the coverage of the cell. The following example is combined with Figure 5. Assume that a network device #0 and a network device #1 each correspond to a cell, and there is terminal device #0 within the coverage of network device #0, and there are terminal device #1 and terminal device #2 within the coverage of network device #1. Then, cross-link interference includes one or more of the following: the signal sent by terminal device #1 interferes with the signal received by terminal device #2, or the signal sent by terminal device #2 interferes with the signal received by terminal device #1. (2) The uplink signal sent by a terminal device within the coverage of a cell interferes with the downlink signal received by another terminal device in a cell adjacent to the cell (neighboring cell). In conjunction with the example of the terminal device and network device provided in Figure 5, it is assumed that the link #0 between network device #0 and terminal device #0 is a downlink; the link #1 between network device #1 and terminal device #1 is an uplink, and the link #2 between network device #1 and terminal device #1 is an uplink. In this case, the cross-link interference may include the interference caused by the signal sent by terminal device #1 to the signal received by terminal device #0, that is, the interference caused by link #1 to link #0, and / or the interference caused by the signal sent by terminal device #2 to the signal received by terminal device #0, that is, the interference caused by link #2 to link #0. The second type of cross-link interference is the cross-link interference between network devices and network devices. In conjunction with the example of the terminal device and network device in Figure 5, the second type of cross-link interference may include: the interference caused by the downlink signal sent by network device #0 to the uplink signal received by network device #1, such as the interference caused by link #0 to link #2, or the interference caused by link #0 to link #3. It should be understood that the second type of cross-link interference may also include: the interference caused by the downlink signal sent by network device #1 to the uplink signal received by network device #0.

[0136] In an SBFD scenario, the measurement reference signal may be distributed across SBFD time units and non-SBFD time units. Combining the filtering principle associated with formula (1) and the inter-link interference generated on SBFD time units, it can be seen that CLI exists on SBFD time units. Therefore, the interference differences between different time units, such as SBFD time units and non-SBFD time units, are large. This will lead to large differences in channel quality between different time units, such as SBFD time units and non-SBFD time units. Therefore, the RRM measurement results obtained by performing RRM measurements according to the filtering scheme shown in formula (1) will result in a single RRM measurement method, which in turn will lead to a single RRM feedback method and limited application scenarios.

[0137] In addition, in the above filtering solution, measurement results on different types of time units affect each other, and the RRM measurement results cannot accurately reflect the link quality of the terminal device.

[0138] The technical solution in this application will be described below with reference to the accompanying drawings.

[0139] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as wireless fidelity (WiFi) systems, vehicle to everything (V2X) communication systems, device-to-device (D2D) communication systems, Internet of Vehicles communication systems, 4th generation (4G) mobile communication systems, such as long term evolution (LTE) systems, world-wide interoperability for microwave access (WiMAX) communication systems, fifth generation (5G) mobile communication systems, such as new radio (NR) systems, and future communication systems, such as sixth generation (6G) mobile communication systems.

[0140] This application will present various aspects, embodiments, or features in the context of systems that may include multiple devices, components, modules, etc. It should be understood and appreciated that each system may include additional devices, components, modules, etc., and / or may not include all of the devices, components, modules, etc. discussed in conjunction with the figures. Furthermore, combinations of these aspects may also be used.

[0141] Additionally, in the embodiments of this application, words such as "exemplarily" and "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as an "exemplary" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of the word "exemplary" is intended to present concepts in a concrete manner.

[0142] First, in this application, "used to indicate" can include being used for direct indication and being used for indirect indication. When describing a certain "information" as being used to indicate A, it can include whether the information directly indicates A or indirectly indicates A, but it does not necessarily mean that the information contains A.

[0143] The information indicated by a message is called information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, where there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can be achieved by means of the arrangement order of each piece of information agreed in advance (such as specified in the protocol), thereby reducing the indication overhead to a certain extent. At the same time, the common parts of each piece of information can be identified and indicated uniformly to reduce the indication overhead caused by indicating the same information separately.

[0144] In addition, the specific indication method can also be various existing indication methods, such as but not limited to the above-mentioned indication methods and various combinations thereof. The specific details of the various indication methods can be referred to the prior art and will not be repeated herein. As can be seen from the above, for example, when it is necessary to indicate multiple information of the same type, there may be a situation where the indication methods for different information are different. In the specific implementation process, the required indication method can be selected according to specific needs. The embodiment of the present application does not limit the selected indication method. In this way, the indication method involved in the embodiment of the present application should be understood to cover various methods that can enable the party to be indicated to obtain the information to be indicated.

[0145] The information to be indicated can be sent as a whole, or divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different. The specific sending method is not limited in this application. Among them, the sending period and / or sending time of these sub-information can be pre-defined, for example, pre-defined according to the protocol, or configured by the transmitting device by sending configuration information to the receiving device. Among them, the configuration information can, for example, but not limited to, include one or a combination of at least two of radio resource control (RRC) signaling, medium access control (MAC) layer signaling and physical layer signaling. Among them, MAC layer signaling, for example, includes MAC control element (CE); physical (PHY) layer signaling, for example, includes downlink control information (DCI).

[0146] Second, in the embodiments shown below, the first, second, and various numerical numbers are only used for the convenience of description and are not intended to limit the scope of the embodiments of the present application.

[0147] Third, “pre-set”, or “pre-defined”, or “pre-configured” can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in a device (for example, including a terminal and a network device), or can be pre-specified in a protocol, and this application does not limit its specific implementation method. Among them, “saving” can mean saving in one or more memories. The one or more memories can be set separately, or integrated in an encoder or decoder, a processor, or a communication device. The one or more memories can also be partially set separately, and partially integrated in a decoder, a processor, or a communication device. The type of memory can be any form of storage medium, and this application does not limit it.

[0156] The network device may be a device with wireless transceiver functions, or may be a chip or chip system provided in the device, located in the access network (AN) of the communication system, and used to provide access services to the terminal device. For example, the network device may be referred to as a radio access network (RAN) device, and may specifically be an access network device of the next generation mobile communication system, such as 6G, such as a 6G base station. In the next generation mobile communication system, the network device may also have other naming methods, all of which are included in the scope of protection of the embodiments of this application, and this application does not impose any limitation on this. Alternatively, the network device may include 5G, such as a gNB in ​​a new radio (NR) system, or one or a group of antenna panels (including multiple antenna panels) of a base station in 5G, or a network node constituting a gNB, a transmission and reception point (TRP or TP), or a transmission measurement function (TMF), such as a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), a radio unit (RU), an RSU with base station functions, a wired access gateway, or a 5G core network element.

[0158] It should be noted that the communication method provided in the embodiment of the present application can be applied between any two nodes shown in Figure 6, such as between terminal devices, between network devices, and between terminal devices and network devices. The specific implementation can refer to the following method embodiment, which will not be repeated here.

[0159] It should be noted that the solutions in the embodiments of the present application can also be applied to other communication systems, and the corresponding names can also be replaced by the names of corresponding functions in other communication systems.

[0160] It should be understood that FIG6 is only a simplified schematic diagram for ease of understanding, and the communication system may also include other network devices and / or other terminal devices, which are not shown in FIG6 .

[0161] In an embodiment of the present application, in order to solve the problem of limited application scenarios of the RRM measurement solution, in one embodiment, a communication method is provided, in which a network device can send RRM measurement configuration information to a terminal device, and the measurement configuration information indicates that filtering processing is performed separately for different types of time units, such as filtering the physical layer measurement results on the SBFD time unit separately, and / or filtering the physical layer measurement results on the non-SBFD time unit separately. In this way, the physical layer measurement results on different types of time units can be filtered separately according to the type of time unit, thereby making RRM measurement more flexible and applicable to more scenarios.

[0162] In other embodiments, a communication method is provided, in which a network device can send RRM measurement configuration information to a terminal device, and the RRM measurement configuration information indicates that filter coefficients are configured separately for different types of time units. In this way, filtering processing can be performed according to the filter coefficients on different types of time units, making RRM measurement more flexible and thus applicable to more scenarios.

[0163] The communication method provided in the embodiment of the present application will be described in detail below with reference to Figures 7 to 13.

[0164] In some embodiments, filtering can be performed separately for physical layer measurement results of different types of time units, such as SBFD time units, and / or filtering can be performed separately for physical layer measurement results of non-SBFD time units. This is described below with reference to FIG7 . FIG7 is a flow chart illustrating a communication method provided in an embodiment of the present application. This communication method can be applied to communication between any two nodes shown in FIG6 .

[0165] As shown in FIG7 , the communication method includes the following steps:

[0166] S701: A network device obtains RRM measurement configuration information.

[0167] RRM measurement configuration information is used to perform RRM measurements. The RRM measurement configuration information indicates the performance of first-type filtering and / or second-type filtering. The first-type filtering corresponds to SBFD time units, while the second-type filtering corresponds to non-SBFD time units. The first-type filtering performs filtering on physical layer measurement results for SBFD time units, while the second-type filtering performs filtering on physical layer measurement results for non-SBFD time units.

[0168] In downlink measurement scenarios, where the measurement reference signal is a downlink signal, non-SBFD time units may include flexible time units or downlink time units. In other words, in downlink measurement scenarios, both flexible time units and downlink time units may be referred to as non-SBFD time units.

[0169] In the embodiment of the present application, the physical layer measurement result on the SBFD time unit, which can also be said to be the physical layer measurement result corresponding to the SBFD time unit, refers to the physical layer measurement result obtained by measuring the reference signal carried on the SBFD, such as CSI-RS or SSB; the physical layer measurement result on the non-SBFD time unit, which can also be said to be the physical layer measurement result corresponding to the non-SBFD time unit, refers to the reference signal on the non-SBFD, such as CSI-RS or SSB, which is not repeated hereafter.

[0170] There is a corresponding relationship between the first type of filtering processing and the SBFD time unit, which means that the first type of filtering processing is performed on the physical layer measurement result on the SBFD time unit.

[0171] There is a corresponding relationship between the second type of filtering processing and the non-SBFD time unit, which means that the second type of filtering processing is performed on the physical layer measurement results in the non-SBFD time unit.

[0172] The first type of filtering and the second type of filtering are L3 filtering or high-layer filtering.

[0173] In the embodiment of the present application, the RRM measurement configuration information is used to instruct to perform the first type of filtering and / or the second type of filtering, including one of the following cases 1 to 3. The following describes each of the cases in combination with different cases.

[0174] Case 1: The RRM measurement configuration information is used to instruct to perform the first type of filtering process, that is, the RRM measurement configuration information is used to instruct to perform the first type of filtering process on the physical layer measurement results in the SBFD time unit alone.

[0175] In a possible implementation, the RRM measurement configuration information may include first RRM measurement configuration information. The first RRM measurement configuration information is associated with a physical layer measurement result on an SBFD time unit.

[0176] Associating the first RRM measurement configuration information with the physical layer measurement result on the SBFD time unit means that the physical layer measurement result on the SBFD time unit is filtered using the filter coefficient configured by the first RRM measurement configuration information.

[0177] In this way, the terminal device can perform filtering processing on the physical layer measurement results on the SBFD time unit separately.

[0178] In one possible implementation scheme, the first RRM measurement configuration information is associated with a first measurement result corresponding to the first measurement quantity, wherein the first measurement result is obtained after performing a first type of filtering processing on the physical layer measurement result corresponding to the first measurement quantity on the SBFD time unit in at least one time unit.

[0179] In this way, by configuring the measurement quantity, such as the first measurement quantity, through the network device, the terminal device can perform filtering processing according to the measurement quantity configured by the network device, thereby improving the flexibility of RRM measurement.

[0180] The first measurement quantity may be one of the following: SINR, RSRQ, or RSSI. In this way, the first measurement quantity may be matched according to the actual scenario, further improving the flexibility of RRM measurement.

[0181] It should be understood that the measurement quantities associated with the first RRM measurement configuration information may be multiple. For example, the measurement quantities associated with the first RRM measurement configuration information may include one or more of the following: SINR, RSRQ, or RSSI.

[0182] In a possible implementation, the first RRM measurement configuration information may include information indicating a first filter coefficient, wherein the first filter coefficient is used to obtain the first measurement result.

[0183] It should be understood that when there are multiple measurement quantities associated with the first RRM measurement configuration information, the filter coefficients corresponding to different measurement quantities may be different. In this case, each combination of a measurement quantity and an SBFD time unit corresponds to a first filter coefficient. Taking the measurement quantities associated with the first RRM measurement configuration information including SINR, RSRQ, and RSSI as an example, the measurement quantities, SBFD time units, and filter coefficients satisfy the corresponding relationship shown in Table 1 below:

[0184] Table 1

[0185] In Table 1 above, each row represents a correspondence between a set of SBFD time units, measurement quantities, and filter coefficients. The measurement quantities corresponding to the SBFD time units are only used as examples. In actual implementation, other correspondences may exist and will not be detailed here.

[0186] In some possible implementations, the first RRM measurement configuration information may include a correspondence between an SBFD time unit, a measurement quantity, and a filter coefficient, such as the correspondence shown in Table 1.

[0187] The first RRM measurement configuration information may indicate the first filter coefficient associated with the physical layer measurement result on the SBFD time unit by direct indication. In this case, the RRM measurement configuration information may include the first filter coefficient. Alternatively, the RRM measurement configuration information may indicate the first filter coefficient associated with the physical layer measurement result on the SBFD time unit by indirect indication. In this case, the RRM measurement configuration information may include an index of the first filter coefficient. Alternatively, the RRM measurement configuration information may include other information that corresponds to the first filter coefficient, which will not be repeated here.

[0188] It should be understood that the above-mentioned first measurement quantity is only used as an example. In actual implementation, the first measurement quantity may also be other possible measurement quantities, such as RSRP. In case 1, the RRM measurement configuration information may be used to indicate that only the physical layer measurement results in the SBFD time unit are subjected to the first type of filtering.

[0189] Case 2: The RRM measurement configuration information is used to instruct to perform the second type of filtering process, that is, the RRM measurement configuration information is used to instruct to perform the second type of filtering process only on the physical layer measurement results in the non-SBFD time unit.

[0190] In a possible implementation, the RRM measurement configuration information includes second RRM measurement configuration information, wherein the second RRM measurement configuration information is associated with a physical layer measurement result on a non-SBFD time unit.

[0191] In this way, the terminal device can perform filtering processing on the physical layer measurement results on the non-SBFD time unit separately.

[0192] Associating the second RRM measurement configuration information with the physical layer measurement result on the non-SBFD time unit means that the physical layer measurement result on the non-SBFD time unit is filtered using the filter coefficient configured by the second RRM measurement configuration information.

[0193] In one possible implementation scheme, the second RRM measurement configuration information is associated with a second measurement result corresponding to the second measurement quantity, and the second measurement result is obtained after performing a second type of filtering processing on the physical layer measurement result corresponding to the second measurement quantity in a non-SBFD time unit in at least one time unit.

[0194] In this way, by configuring the measurement quantity, such as the second measurement quantity, through the network device, the terminal device can perform filtering processing according to the measurement quantity configured by the network device, thereby improving the flexibility of RRM measurement.

[0195] The second measurement quantity is one of the following: SINR, RSRQ, or RSSI. In this way, the measurement quantity can be matched according to the actual scenario, further improving the flexibility of RRM measurement.

[0196] The measurement quantities associated with the second RRM measurement configuration information may be multiple. For example, the measurement quantities associated with the second RRM measurement configuration information may include one or more of the following: SINR, RSRQ, or RSSI.

[0197] In one possible design, RRM measurement configuration information, such as second RRM measurement configuration information, may include information indicating a second filter coefficient, where the second filter coefficient is used to obtain a second measurement result.

[0198] It should be understood that when there are multiple measurement quantities associated with the second RRM measurement configuration information, the filter coefficients corresponding to different measurement quantities may be different. In this case, each combination of a measurement quantity and a non-SBFD time unit corresponds to a first filter coefficient. Taking the measurement quantities associated with the second RRM measurement configuration information including SINR, RSRQ, and RSSI as an example, the measurement quantities, non-SBFD time units, and filter coefficients satisfy the corresponding relationship shown in Table 2 below:

[0199] Table 2

[0200] In Table 2 above, each row represents a correspondence between a set of non-SBFD time units, measurement quantities, and filter coefficients. The measurement quantities corresponding to the non-SBFD time units are only used as examples. In actual implementation, other correspondences may exist and are not detailed here.

[0201] In some possible implementations, the second RRM measurement configuration information may include a correspondence between a non-SBFD time unit, a measurement quantity, and a filter coefficient, such as the correspondence shown in Table 2.

[0202] Among them, the RRM measurement configuration information, such as the second RRM measurement configuration information, can indicate the second filter coefficient associated with the physical layer measurement result on the non-SBFD time unit by direct indication. In this case, the RRM measurement configuration information can include the second filter coefficient. Alternatively, the RRM measurement configuration information can indicate the second filter coefficient associated with the physical layer measurement result on the non-SBFD time unit by indirect indication. In this case, the RRM measurement configuration information can include the index of the second filter coefficient. Alternatively, the RRM measurement configuration information can include other information that corresponds to the second filter coefficient, which will not be repeated here.

[0203] It should be understood that the above second measurement quantity is for example only. In actual implementation, the second measurement quantity may also be other possible measurement quantities, such as RSRP. In case 2, the RRM measurement configuration information may be used to indicate that the second type of filtering is performed only on the physical layer measurement results in non-SBFD time units.

[0204] In addition, in Table 1 and Table 2 above, any two filter coefficients may be the same or different, for example, the first filter coefficient #1 and the second filter coefficient #3 may be the same or different.

[0205] In case 3, the RRM measurement configuration information is used to instruct the first type of filtering and the second type of filtering, that is, to instruct the first type of filtering to be performed only on the physical layer measurement results in the SBFD time unit, and to perform the second type of filtering only on the physical layer measurement results in the non-SBFD time unit.

[0206] In case 3.1, the RRM measurement configuration information includes first RRM measurement configuration information and second RRM measurement configuration information. In this case, the first RRM measurement configuration information can refer to the relevant introduction in case 1, and the second RRM measurement configuration information can refer to the relevant introduction in case 2.

[0207] The following example illustrates RRM measurement configuration information. As shown in Figure 8, the RRM measurement configuration information includes first RRM measurement configuration information and second RRM measurement configuration information, wherein the first RRM measurement configuration information associates a first measurement result corresponding to RSRQ with a first measurement result corresponding to SINR. The second RRM measurement configuration information associates a second measurement result corresponding to RSRQ with a second measurement result associated with SINR.

[0208] In case 3.2, the RRM measurement configuration information includes third RRM measurement configuration information. The third RRM measurement configuration information is associated with physical layer measurement results for SBFD time units and physical layer measurement results for non-SBFD time units. In this case, the implementation principles of the third RRM measurement configuration information can refer to the descriptions of the first and second RRM measurement configuration information. This reduces the amount of RRM measurement configuration information and reduces resource overhead.

[0209] In one possible implementation, the third RRM measurement configuration information associates a first measurement result corresponding to the first measurement quantity with a second measurement result corresponding to the second measurement quantity, where the first measurement result is obtained by performing a first type of filtering processing on a physical layer measurement result corresponding to the first measurement quantity in an SBFD time unit among multiple time units. The second measurement result is obtained by performing a second type of filtering processing on a physical layer measurement result corresponding to the second measurement quantity in a non-SBFD time unit among the multiple time units.

[0210] Among them, the third RRM measurement configuration information can associate multiple measurement quantities, the result of the physical layer measurement result on the SBFD time unit corresponding to each measurement quantity after the first type of filtering processing, and the result of the physical layer measurement result on the non-SBFD time unit corresponding to each measurement quantity after the second type of filtering processing.

[0211] The following example illustrates the association relationship between the third RRM measurement configuration information and the measurement quantity, the first measurement result, and the second measurement result. As shown in Figure 9, the third RRM measurement configuration information associates the first measurement result corresponding to RSRQ with the second measurement result corresponding to RSRQ, and associates the first measurement result corresponding to SINR with the second measurement result corresponding to SINR.

[0212] In one possible implementation, the third RRM measurement configuration information includes information for indicating a first filter coefficient and a second filter coefficient, wherein the first filter coefficient is used to obtain a first type of measurement result, such as a first measurement result; and the second filter coefficient is used to obtain a second type of measurement result, such as a second measurement result.

[0213] In this way, different filter coefficients can be matched according to the interference conditions between different links, thereby making the RRM measurement results more accurate.

[0214] It should be understood that the RRM measurement configuration information may also include other information of the RRM configuration information, such as existing information. The first filter coefficient and the second filter coefficient may be the same or different. In the embodiment of the present application, the measurement amount may also be understood as a measurement indicator.

[0215] S702: The network device sends RRM measurement configuration information. Correspondingly, the terminal device receives the RRM measurement configuration information.

[0216] The fourth RRM measurement configuration information may be carried in higher layer signaling, for example, in RRC signaling or MAC-CE.

[0217] It should be understood that the "sending" in the network device sending RRM measurement configuration information can also be understood as output, or includes the meaning of "output", and sending RRM measurement configuration information can also be understood as outputting RRM measurement configuration information. The network device sending RRM measurement configuration information may include the process of the network device processing the RRM measurement configuration information through the high-level protocol, sending it to the physical layer for modulation and transmitting the modulated signal. For example, in the O-RAN scenario, the network device sending RRM measurement configuration information may include: the CU sending RRM measurement configuration information to the DU, and the DU sending RRM measurement configuration information to the RU.

[0218] S703: The terminal device performs the first type of filtering processing and / or the second type of filtering processing according to the RRM measurement configuration information.

[0219] The following describes different methods in combination with different situations of RRM measurement configuration information.

[0220] Method 1: When the RRM measurement configuration information is as shown in the above situation 1, S303 may include: the terminal device performs a first type of filtering process according to the RRM measurement configuration information to obtain a first type of measurement result.

[0221] The terminal device performs the first type of filtering processing based on the RRM measurement configuration information to obtain the first type of measurement result. This means that the terminal device performs the first type of filtering processing on the physical layer measurement results on the SBFD time unit based on the RRM measurement configuration information, that is, the terminal device performs the first type of filtering processing on the physical layer measurement results on the SBFD time unit alone to obtain the first type of measurement result. It should be understood that in this case, the terminal device may perform the first type of filtering processing only on the physical layer results on the SBFD time unit.

[0222] In this way, the physical layer measurement results on the SBFD time unit can be filtered separately.

[0223] Among them, when the RRM measurement configuration information is as shown in the above situation 1, the terminal device performs the first type of filtering processing according to the RRM measurement configuration information. In other words, the terminal device performs the first type of filtering processing according to the first RRM measurement configuration information. That is, the terminal device performs the first type of filtering processing on the physical layer measurement result on the SBFD time unit according to the first RRM measurement configuration information.

[0224] It should be understood that the first category of measurement results is a result obtained by filtering the physical layer measurement results on the SBFD time unit. The first category of measurement results may include a result obtained by filtering the physical layer measurement results corresponding to each measurement quantity on the SBFD time unit, that is, a first measurement result corresponding to each measurement quantity. If the first RRM measurement configuration information is associated with the first measurement result corresponding to the first measurement quantity, then the first measurement result belongs to the first category of filtering processing results.

[0225] For ease of understanding, the following description is given with reference to time units 1 to 5 shown in FIG10 .

[0226] Assume that time unit 1 is a non-SBFD time unit, time units 2 to 4 are all SBFD time units, time unit 5 is an uplink time unit, the first filter coefficient indicated by the RRM measurement configuration information is a1, and the physical layer measurement results on time units 1 to 4 correspond to: X1, X2, X3, X4, then the terminal device uses the first filter coefficient a1 to filter the physical layer measurement results on time units 2 to 4. Assume that the physical layer measurement results of the first filtering process to the third filtering process on the SBFD time unit are represented by M1, M2, and M3, then, for the SBFD time unit, the first filtering process uses the first filter coefficient a1 for filtering, and the measurement result F1 after the first filtering process satisfies the relationship shown in the following formula (6): F1=(1–a1)*F0+a1*M1; (6)

[0227] Among them, F0=M1. When the physical layer measurement result of the first filtering processing is the physical layer measurement result X2 on time unit 2, M1=X2, that is, M1 is equal to the physical layer measurement result on time unit 2, and F0=X2, that is, F0 is equal to the physical layer measurement result on time unit 2.

[0228] For the SBFD time unit, the second filtering process uses the first filtering coefficient a1 for filtering. The measurement result F2 after the second filtering process satisfies the relationship shown in the following formula (7): F2 = (1–a1)*F1+a1*M2; (7)

[0229] In which case, when the physical layer measurement result of the second filtering process is the physical layer measurement result X3 on time unit 3, M2=X3, that is, M2 is equal to the physical layer measurement result on time unit 3.

[0230] For the SBFD time unit, the third filtering process uses the first filtering coefficient a1 for filtering. The result F3 after the third filtering process satisfies the relationship shown in the following formula (8): F3=(1–a1)*F2+a1*M3; (8)

[0231] In which case, when the physical layer measurement result of the third filtering process is the physical layer measurement result X4 on time unit 4, M3=X4, that is, M4 is equal to the physical layer measurement result on time unit 4.

[0232] In combination with the relevant introduction of the above formulas (6) to (8), it can be seen that the first type of measurement result is the measurement result F3 after filtering the physical layer measurement results on time unit 2 to time unit 4.

[0233] Method 2: When the RRM measurement configuration information is as shown in the above situation 2, S303 may include: the terminal device performs a second type of filtering process according to the RRM measurement configuration information to obtain a second type of measurement result.

[0234] The terminal device performs the second type of filtering processing according to the RRM measurement configuration information. The terminal device performs the second type of filtering processing on the physical layer measurement results on the non-SBFD time unit according to the RRM measurement configuration information, that is, the second type of filtering processing is performed on the physical layer measurement results on the non-SBFD time unit alone to obtain the second type of measurement results.

[0235] In this way, the physical layer measurement results in non-SBFD time units can be filtered separately.

[0236] When the RRM measurement configuration information is as shown in the above situation 2, the terminal device performs the second type of filtering processing according to the RRM measurement configuration information. In other words, the terminal device performs the second type of filtering processing according to the second RRM measurement configuration information. That is, the terminal device performs the second type of filtering processing on the physical layer measurement results on the non-SBFD time unit according to the second RRM measurement configuration information.

[0237] It should be understood that the second category of measurement results is obtained by filtering the physical layer measurement results on the non-SBFD time unit. The second category of measurement results may include the results obtained by filtering the physical layer measurement results corresponding to each measurement quantity on the non-SBFD time unit, that is, the second measurement result corresponding to each measurement quantity. If the second RRM measurement configuration information is associated with the second measurement result corresponding to the first measurement quantity, then the second measurement result belongs to the second category of filtering processing results.

[0238] The following describes the time units 1 to 5 as examples.

[0239] Assume that time unit 1 is a non-SBFD time unit, time unit 2 and time unit 4 are both SBFD time units, time unit 5 is an uplink time unit, the second filter coefficient is a2, and the physical layer measurement results on time unit 1 to time unit 4 correspond to: X1, X2, X3, X4, then, the terminal device uses the second filter coefficient a2 to filter the physical layer measurement results on time unit 1 to obtain the RRM measurement result.

[0240] In this case, the non-SBFD time unit is time unit 1, and the measurement result F1 after filtering the physical layer measurement result on time unit 1 satisfies the relationship shown in the following formula (9): F1=(1–a2)*F0+a2*M1; (9)

[0241] In the case where the physical layer measurement result of the first filtering process is the physical layer measurement result X1 on time unit 1, M1=X1, F0=M1, that is, F0 is equal to the physical layer measurement result on time unit 1. The second type of measurement result is the measurement result F1 after the physical layer measurement result on time unit 1 is filtered.

[0242] It should be understood that when the number of filtering processing of the physical layer measurement results on the non-SBFD time unit is multiple times, the principle of the nth filtering processing of the physical layer measurement results on the non-SBFD time unit is similar to the principle of the nth filtering processing of the physical layer measurement results on the SBFD time unit, and will not be repeated here.

[0243] Method three: When the RRM measurement configuration information is as shown in the above situation 3, S303 may include: the terminal device performs the first type of filtering processing and the second type of filtering processing according to the RRM measurement configuration information. That is, the terminal device performs the first type of filtering processing according to the RRM measurement configuration information, and the terminal device performs the second type of filtering processing according to the RRM measurement configuration information.

[0244] In case 3.2, the terminal device performs the first type of filtering and / or the second type of filtering according to the RRM measurement configuration information, including: the terminal device performs the first type of filtering on the physical layer measurement results of the SBFD time unit in the multiple time units according to the third RRM measurement configuration information to obtain the first type of measurement results. And, the terminal device performs the second type of filtering on the physical layer measurement results of the non-SBFD time unit in the multiple time units according to the third RRM measurement configuration information to obtain the second type of measurement results. In this way, the terminal device can separately filter the physical layer measurement results of the SBFD time unit and separately filter the physical layer measurement results of the non-SBFD time unit.

[0245] Regarding the principle of the terminal device performing the first type of filtering according to the RRM measurement configuration information, please refer to the relevant introduction in Method 1, and regarding the principle of the terminal device performing the second type of filtering according to the RRM measurement configuration information, please refer to the relevant introduction in Method 2. No further details will be given here.

[0246] Taking the physical layer measurement results on a time unit including physical layer measurement results #1 to #4 as an example, if physical layer measurement results #1 and #4 are physical layer measurement results on an SBFD time unit, and physical layer measurement results #2 and #3 are physical layer measurement results on a non-SBFD time unit, then, as shown in FIG11 , filtering processing is performed on physical layer measurement results #1 and #4 to obtain a first type of measurement result, and filtering processing is performed on physical layer measurement results #2 and #3 to obtain a second type of measurement result.

[0247] It should be understood that in the embodiments of the present application, the physical layer processing results of different measurement quantities in the same type of time unit, such as an SBFD time unit or a non-SBFD time unit, are processed independently. For example, for an SBFD time unit, the physical layer measurement result corresponding to the measurement quantity SINR is independently subjected to the first type of filtering processing, and the physical layer measurement result corresponding to the measurement quantity RSRQ is independently subjected to the first type of filtering processing.

[0248] S704: The terminal device performs cell management based on the filtered measurement results.

[0249] In one possible implementation, if the terminal device is in a connected state, S704 may include: the terminal device sending the filtered measurement result. Correspondingly, the network device receives the filtered measurement result. That is, the terminal device reports the first type of measurement result and / or the second type of measurement result.

[0250] It should be understood that if the RRM measurement configuration information is as in Case 1 above, the terminal device reports the first type of measurement results.

[0251] If the RRM measurement configuration information is as in Case 2 above, the terminal device reports the second type of measurement results.

[0252] If the RRM measurement configuration information is as in Case 3 above, the terminal device may report the first category measurement results, or the second category measurement results, or both the first category measurement results and the second category measurement results. In this case, which of the first category measurement results and the second category measurement results the terminal specifically reports may be determined by protocol agreement, or by network device configuration, or by the size of the first category measurement results and the second category measurement results. For example, measurement results exceeding the corresponding threshold value may be reported.

[0253] In one possible implementation, the terminal device reporting the first category measurement result and / or the second category measurement result may include: the terminal device reporting the first category measurement result and / or the second category measurement result periodically, or the terminal device reporting the first category measurement result and / or the second category measurement result at one or more preset moments. Among the multiple preset moments, the interval between any two adjacent preset moments has the same length.

[0254] In a possible implementation, the terminal device may report the first type of measurement results and / or the second type of measurement results in an event-triggered manner.

[0255] For example, the terminal device may send the first category measurement results and / or the second category measurement results according to the size of at least one of the first category measurement results and the second category measurement results.

[0256] In case 1, the terminal device may send the first category measurement result according to the size of at least one of the first category measurement result and the second category measurement result.

[0257] For example, the terminal device may send the first type of measurement result when the first type of measurement result is greater than or equal to a first threshold, and / or when the second type of measurement result is greater than or equal to a second threshold.

[0258] In case 2, the terminal device may send the second type of measurement results according to the size of at least one of the first type of measurement results and the second type of measurement results.

[0259] For example, the terminal device may send the first type of measurement result when the first type of measurement result is greater than or equal to the third threshold, and / or when the second type of measurement result is greater than or equal to the fourth threshold.

[0260] In case 3, the terminal device may send the first category measurement results and the second category measurement results according to the size of at least one of the first category measurement results and the second category measurement results.

[0261] The terminal device may send the first-category measurement result and the second-category measurement result when the first-category measurement result is greater than or equal to the fifth threshold, and / or when the second-category measurement result is greater than or equal to the sixth threshold.

[0262] In one possible design, if the terminal device is in an idle state or an inactive state, the terminal device selects a cell or reselects a cell based on a filtered measurement result.

[0263] The terminal device sends the first type of measurement results, which enables the network device to obtain the RRM measurement results for cell switching, thereby improving the service continuity of the terminal device. The terminal device selects and / or reselects a cell based on the first type of measurement results, thereby improving the service continuity of the terminal device.

[0264] The terminal device sends the second type of measurement results, which allows the network device to obtain the RRM measurement results for cell switching, thereby improving the service continuity of the terminal device. The terminal device selects and / or reselects a cell based on the second type of measurement results, thereby improving the service continuity of the terminal device.

[0265] Regarding the implementation of the terminal device performing cell selection and / or reselection based on the third type of measurement results, reference may be made to the existing implementation methods for cell selection and / or reselection, which will not be repeated here.

[0266] Based on the communication method provided in Figure 7, the network device can generate and send RRM measurement configuration information, and the terminal device can perform filtering processing according to the RRM measurement configuration information. Since the RRM measurement configuration information indicates different types of time units, such as the physical layer measurement results on SBFD time units and non-SBFD time units, each adopts a filtering processing method, such as the first type of filtering processing and the second type of filtering processing mentioned above, the terminal device can perform filtering processing on the physical layer measurement results on different types of time units separately according to the filtering processing method corresponding to each type of time unit, which can make RRM measurement and reporting more flexible and applicable to more scenarios.

[0267] In addition, by filtering the physical layer measurement results on different types of time units separately according to the filtering processing mode corresponding to each type of time unit, mutual influence between the filtering results on different time units can be avoided, thereby improving the accuracy of RRM measurement.

[0268] In some embodiments, different filtering coefficients can be configured for different types of time units, and the physical layer measurement results on different types of time units can be combined and filtered. In this case, the communication method provided by the embodiment of the present application is shown in Figure 12. The method provided in Figure 12 includes S1201 to S1203:

[0269] S1201: The network device generates fourth RRM measurement configuration information.

[0270] The fourth RRM measurement configuration information is used to indicate a third filter coefficient associated with a physical layer measurement result on an SBFD time unit and a fourth filter coefficient associated with a physical layer measurement result on a non-SBFD time unit.

[0271] The third filter coefficient is a coefficient used to filter the physical layer measurement result in the SBFD time unit, and the fourth filter coefficient is a coefficient used to filter the physical layer measurement result in the non-SBFD time unit.

[0272] It should be understood that, for example, filtering the physical layer measurement results on the SBFD time unit is layer 3 filtering (or high-layer filtering), and filtering the physical layer measurement results on the non-subband non-full-duplex time unit is also layer 3 filtering (or high-layer filtering).

[0273] It is understood that the filter coefficient associated with the physical layer measurement result on time unit A refers to the filter coefficient used to filter the physical layer measurement result on time unit A. The filter coefficient associated with the physical layer measurement result on time unit A can also be said to be the filter coefficient corresponding to the physical layer measurement result on time unit A. The third filter coefficient associated with the physical layer measurement result on the SBFD time unit refers to the filter coefficient used to filter the physical layer measurement result on the SBFD time unit, and the fourth filter coefficient associated with the physical layer measurement result on the non-SBFD time unit refers to the filter coefficient used to filter the physical layer measurement result on the non-SBFD time unit. It is understood that the fourth RRM measurement configuration information can directly indicate the third filter coefficient associated with the physical layer measurement result on the SBFD time unit. In this case, the fourth RRM measurement configuration information can include the third filter coefficient. Alternatively, the fourth RRM measurement configuration information can indirectly indicate the third filter coefficient associated with the physical layer measurement result on the SBFD time unit. In this case, the fourth RRM measurement configuration information can include an index of the third filter coefficient or other information corresponding to the third filter coefficient. This will not be further described here.

[0274] Similarly, the fourth RRM measurement configuration information may indicate the fourth filter coefficient associated with the physical layer measurement result on the non-SBFD time unit by direct indication. In this case, the fourth RRM measurement configuration information may include the fourth filter coefficient. Alternatively, the fourth RRM measurement configuration information may indicate the fourth filter coefficient associated with the physical layer measurement result on the non-SBFD time unit by indirect indication. In this case, the fourth RRM measurement configuration information may include an index of the fourth filter coefficient or other information corresponding to the fourth filter coefficient, which will not be repeated here.

[0275] In one possible implementation scheme, the fourth RRM measurement configuration information is associated with the third measurement result corresponding to the third measurement quantity, and the third measurement result is obtained by filtering the physical layer measurement result corresponding to the third measurement quantity on the SBFD time unit and the physical layer measurement result corresponding to the third measurement quantity on the non-SBFD time unit.

[0276] In a possible implementation, the third measurement quantity includes at least one of the following: SINR, RSRQ, or RSSI. That is, the fourth RRM measurement configuration information may be associated with one or more measurement quantities.

[0277] In this case, the measurement quantity can be configured according to the actual scenario, making the RRM measurement more flexible.

[0278] It should be understood that the third measurement quantity is only used as an example. In actual implementation, the third measurement quantity may also be other possible measurement quantities, such as RSRP.

[0279] In this case, the physical layer measurement result on the SBFD time unit refers to the physical layer measurement result corresponding to the third measurement quantity on the SBFD time unit, and the physical layer measurement result on the non-SBFD time unit refers to the physical layer measurement result corresponding to the third measurement quantity on the non-SBFD time unit. Each third measurement quantity corresponds to two filter coefficients, namely the third filter coefficient and the fourth filter coefficient. In combination with the above, it can be seen that each combination of a measurement quantity and an SBFD time unit corresponds to a third filter coefficient, and each combination of a measurement quantity and a non-SBFD time unit corresponds to a fourth filter coefficient. Taking the third measurement quantity including SINR, RSRQ and RSSI as an example, the measurement quantity, time unit and filter coefficient satisfy the corresponding relationship shown in Table 3 below:

[0280] Table 3

[0281] In Table 3, each row represents a correspondence between a set of time units, measurement quantities, and filter coefficients. For multiple time units, the correspondence between the measurement quantities corresponding to SBFD time units and the measurement quantities corresponding to non-SBFD time units in the multiple time units shown in Table 3 is for example only. In actual implementations, other correspondences may exist and are not further described here.

[0282] In some embodiments, the fourth RRM measurement configuration information may include a correspondence between a time unit, a measurement amount, and a filter coefficient, such as the correspondence shown in Table 3.

[0283] The first filter coefficients corresponding to different measurement quantities may be the same or different. The second filter coefficients corresponding to different measurement quantities may be the same or different.

[0284] It should be understood that, in multiple time units, the third filter coefficient corresponding to a combination of a measurement metric and an SBFD time unit and the fourth filter coefficient corresponding to a combination of the measurement metric and a non-SBFD time unit may be the same or different. For example, with reference to Table 3, if the measurement metric for the SBFD time unit in the multiple time units is SINR, and the measurement metric for the non-SBFD time unit in the multiple time units is SINR, then the third filter coefficient #1 and the fourth filter coefficient #1 may be the same or different.

[0285] S1202: The network device sends fourth RRM measurement configuration information. Correspondingly, the terminal device receives the fourth RRM measurement configuration information.

[0286] The fourth RRM measurement configuration information may be carried in higher layer signaling, for example, in RRC signaling or MAC-CE.

[0287] S1203: The terminal device filters the physical layer measurement results of the SBFD time unit and the physical layer measurement results of the non-SBFD time unit in the multiple time units according to the third filter coefficient and the fourth filter coefficient to obtain a third type of measurement results.

[0288] It can be seen that the third type of measurement results are obtained by the terminal device filtering the physical layer measurement results on multiple time units according to the fourth RRM measurement configuration.

[0289] In the case where the fourth RRM configuration is associated with the third measurement quantity, the third category of measurement results includes the third measurement result corresponding to each third measurement quantity, or in other words, the third measurement result belongs to the third category of measurement results.

[0290] In this way, the measurement quantity, such as the third measurement quantity mentioned above, can be configured through the network device, which can improve the flexibility of RRM measurement.

[0291] In one possible implementation scheme, the terminal device filters the physical layer measurement results on the SBFD time unit in multiple time units and the physical layer measurement results on the non-SBFD time unit according to the third filter coefficient and the fourth filter coefficient, which means that the physical layer measurement results of the third measurement quantity on the SBFD time unit in multiple time units and the physical layer measurement results corresponding to the third measurement quantity on the non-SBFD time unit are filtered according to the third filter coefficient and the fourth filter coefficient.

[0292] That is to say, when filtering each of the multiple time units, the physical layer measurement results on the SBFD time unit are filtered using the third filter coefficient, and the physical layer measurement results on the non-SBFD time unit are processed using the fourth filter coefficient. It should be understood that the physical layer measurement results corresponding to each measurement quantity in different time units are filtered separately. For example, assuming that the third measurement quantity includes SINR, RSRQ, and RSSI, then the physical layer measurement quantity corresponding to SINR in multiple time units is filtered separately to obtain a third measurement result; the physical layer measurement result corresponding to RSRQ in multiple time units is filtered separately to obtain a third measurement result; the physical layer measurement result corresponding to RSSI in multiple time units is filtered separately to obtain a third measurement result. For ease of understanding, the following uses SINR as an example to illustrate the principle of filtering in the embodiment of the present application.

[0293] For ease of understanding, the following description is given with reference to the time unit shown in FIG13 .

[0294] Assume that time unit 1 is a non-SBFD time unit, time unit 2 and time unit 4 are SBFD time units, and time unit 5 is an uplink time unit. The physical layer measurement results of time units 1 to 4 correspond to: X1, X2, X3, X4, respectively. Assume that the physical layer measurement results of the first filtering process to the third filtering process are represented by M1, M2, M3 and M4, respectively, the third filtering coefficient is a3, and the fourth filtering coefficient is a4. Then, the first filtering process uses the third filtering coefficient a4 for filtering. The measurement result F1 after the first filtering process satisfies the relationship shown in the following formula (10): F1 = (1–a4)*F0 + a4*M1; (10)

[0295] Among them, F0=M1. When the physical layer measurement result of the first filtering processing is the physical layer measurement result X1 on time unit 1, M1=X1, that is, M1 is equal to the physical layer measurement result on time unit 1, and F0 is equal to the physical layer measurement result on time unit 1.

[0296] The second filtering process uses the third filtering coefficient a3 for filtering. The result F2 after the second filtering process satisfies the relationship shown in the following formula (11): F2=(1–a3)*F1+a3*M2; (11)

[0297] In which case, when the physical layer measurement result of the second filtering process is the physical layer measurement result X2 on time unit 2, M2=X2, that is, M2 is equal to the physical layer measurement result on time unit 2.

[0298] The third filtering process uses the third filtering coefficient a3 for filtering. The result F3 after the third filtering process satisfies the relationship shown in the following formula (12): F3=(1–a3)*F2+a3*M3; (12)

[0299] In which case, when the physical layer measurement result of the third filtering process is the physical layer measurement result X3 on time unit 3, M3=X3, that is, M3 is equal to the physical layer measurement result on time unit 3.

[0300] The fourth filtering process uses the third filtering coefficient a3 for filtering. The result F4 after the fourth filtering process satisfies the relationship shown in the following formula (13): F4=(1–a3)*F3+a3*M4; (13)

[0301] In which case, when the physical layer measurement result of the fourth filtering process is the physical layer measurement result X4 on time unit 4, M4=X4, that is, M4 is equal to the physical layer measurement result on time unit 4.

[0302] In combination with the relevant introduction of the above formulas (10) to (13), it can be seen that the third measurement result is the measurement result F4 after filtering the physical layer measurement results on time units 1 to 4. In this case, the third measurement result is a third type of measurement result.

[0303] It should be understood that, when the fourth RRM measurement configuration information is associated with the third measurement result corresponding to the third measurement quantity, the third measurement result belongs to the third category of measurement results.

[0304] The above third measurement quantity is only used as an example. In actual implementation, there may be multiple third measurement quantities. In this case, each third measurement quantity may be filtered according to the principle shown in FIG12 , wherein the filtering processes of different third measurement quantities are independent of each other.

[0305] In addition, the method provided in FIG. 12 may further include S1204 .

[0306] S1204: The terminal device performs cell management based on the third type of measurement results.

[0307] In a possible design solution, if the terminal device is in a connected state, S1204 may include: the terminal device sends the third type of measurement result. Correspondingly, the network device receives the third type of measurement result.

[0308] Among them, the terminal device sends the third type of measurement results, which allows the network device to obtain the RRM measurement results for use in cell switching, thereby improving the service continuity of the terminal device.

[0309] Regarding the implementation of the terminal device sending the third type of measurement results and the network device receiving the third type of measurement results, reference can be made to the implementation method of the terminal device reporting the measurement results to the network device in the existing technology, which will not be repeated here.

[0310] In a possible implementation, if the terminal device is in an idle state or an inactive state, the terminal device may perform cell selection and / or reselection based on the third type of measurement result.

[0311] The terminal device performs cell selection and / or reselection based on the third type of measurement result, which can improve the service continuity of the terminal device.

[0312] Regarding the implementation of the terminal device performing cell selection and / or reselection based on the third type of measurement results, reference may be made to the existing implementation methods for cell selection and / or reselection, which will not be repeated here.

[0313] Based on the method provided in Figure 12, the terminal device can perform filtering processing according to the fourth RRM measurement configuration information. Since the physical layer measurement results of different types of time units in the fourth RRM measurement configuration information, such as SBFD time units and non-SBFD time units, are each associated with a filtering coefficient, such as the third filtering coefficient and the fourth filtering coefficient mentioned above, when the terminal device filters the physical layer measurement results on different types of time units, it can use filtering coefficients corresponding to different types of time units, making RRM measurement more flexible and applicable to more scenarios.

[0314] In addition, the filter coefficients can be matched according to different types of time units, thereby improving the accuracy of RRM measurements.

[0315] The communication method provided in the embodiment of the present application is described in detail above in conjunction with Figures 7 to 13.
