[0045] In some embodiments, both network device 110 and UE 120 support the 3rd Generation Partnership Project (3GPP) protocol, but are not limited to the 3GPP protocol.

[0046] In some embodiments, the frequency bands supported by the wireless communication system 100 include, but are not limited to: Sub-6GHz bands (e.g., bands in the range of 450MHz-6GHz), Sub-7GHz bands (e.g., 2.4GHz, 5GHz, 6GHz, etc., which belong to the range of 1 to 7.25GHz), and millimeter wave (mmWave) bands (e.g., 26GHz, 28GHz, 39GHz, 45GHz, 60GHz, etc., which belong to the range of 24.25 to 300GHz).

[0047] The technical solutions described in some embodiments of this application can be applied to various communication systems, such as: 6th-Generation (6G) systems, subsequent evolution systems of 6G, NR systems, evolution systems of NR systems, 5th-Generation (5G) systems, Beyond 5th-Generation (B5G) systems, Long Term Evolution (LTE) systems, Advanced Long Term Evolution (LTE-A) systems, LTE-based access to unlicensed spectrum (LTE-U) systems, NR-based access to unlicensed spectrum (NR-U) systems, cellular IoT systems, Wireless Local Area Networks (WLAN) systems, Wireless Fidelity (Wi-Fi) systems, Global System for Mobile Communication (GSM) systems, Code Division Multiple Access (CDMA) systems, and Wideband Code Division Multiple Access (CDMA) systems. Systems such as WCDMA (Wide-accessible communication network), General Packet Radio Service (GPRS), Terrestrial Networks (TN), and Non-Terrestrial Networks (NTN) are included.

[0048] The wireless communication system 100 is applicable to three communication scenarios: the first is the uplink (UL) transmission scenario, which refers to the scenario where the UE sends signals to the network device; the second is the downlink (DL) transmission scenario, which refers to the scenario where the network device sends signals to the UE; and the third is the sidelink transmission scenario, which refers to the scenario where the UE sends signals to other UEs.

[0049] Taking the NR system as an example, it supports network devices to send semi-static uplink / downlink configuration signaling and / or dynamic uplink / downlink indication signaling to configure the time slot structure for the UE.

[0050] Semi-static uplink / downlink configuration signaling includes tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated. tdd-UL-DL-ConfigurationCommon is used to configure a common time slot structure, i.e., a time slot structure applicable to all UEs within the cell. This signaling can configure one or two patterns, each corresponding to one period. Network devices can configure the time slot structure within each pattern, mainly including one or more of the following parameters: reference subcarrier spacing μ. ref Period (denoted as P, which is the period parameter of the pattern, in milliseconds (ms)), number of downlink time slots d slot Downlink symbol number d sym Uplink time slot number u slot Up row sign number u sym .

[0051] Based on the reference subcarrier spacing μ ref The period P can determine the total number S of time slots included in that period, and the first d of those S time slots... slot Each time slot represents a full downlink time slot, and the first d in the time slot following the last full downlink time slot. sym Each symbol represents a downlink symbol; the last u in the S time slots slot Each time slot represents a full uplink time slot, and the last u in the time slot preceding the first full uplink time slot... sym One symbol represents the uplink symbol; the remaining symbols in the cycle represent flexible symbols. Therefore, within a pattern cycle, the overall frame structure configuration is downlink time slots or downlink symbols first, uplink time slots or uplink symbols second, and flexible time slots or flexible symbols in between. The UE can determine the time slot structure within a cycle based on tdd-UL-DL-ConfigurationCommon, and the time slot structure of all time slots can be determined by repeating the cycle P in the time domain.

[0052] Figure 2 illustrates a time slot structure configuration of a pattern provided in an exemplary embodiment of this application. The pattern has a period P = 5ms. With a subcarrier spacing of 15kHz, one period of the pattern includes 5 time slots, where d slot =1,d sym =2, u slot =1, u sym=6. That is, within a 5ms period, the first time slot is a full downlink time slot, the first two symbols in the second time slot are downlink symbols, the last time slot is a full uplink time slot, the last six symbols in the penultimate time slot are uplink symbols, and the remaining symbols are flexible symbols. This pattern repeats periodically in the time domain at 5ms.

[0053] Network devices can simultaneously configure two patterns using tdd-UL-DL-ConfigurationCommon, with periods P and P2 respectively, and configure the time slot structure for each pattern. If a network device configures two patterns simultaneously, the total period (P+P2) of the two patterns is divisible by 20ms. The time slot structures of the two patterns repeat together in the time domain, that is, they repeat periodically in the time domain with a period (P+P2), thus determining the time slot structure for all time slots.

[0054] Network devices can configure the time slot structure for a UE using tdd-UL-DL-ConfigurationDedicated, a UE-specific Radio Resource Control (RRC) signaling. tdd-UL-DL-ConfigurationDedicated configures the time slot structure for a set of time slots within the period configured by tdd-UL-DL-ConfigurationCommon, primarily including the following parameters: time slot index and symbol direction. The time slot index parameter indicates a time slot within the period configured by tdd-UL-DL-ConfigurationCommon. The symbol direction parameter configures a set of symbols within the time slot. It can be used to configure the time slot corresponding to the time slot index parameter to include all downlink symbols (i.e., all symbols in the time slot corresponding to the time slot index parameter are downlink symbols), or to configure the time slot corresponding to the time slot index parameter to include all uplink symbols (i.e., all symbols in the time slot corresponding to the time slot index parameter are uplink symbols), or to configure the number of downlink symbols in the time slot corresponding to the time slot index parameter, or to configure the number of uplink symbols in the time slot corresponding to the time slot index parameter.

[0055] `tdd-UL-DL-ConfigurationDedicated` can only change the transmission direction of flexible symbols configured by `tdd-UL-DL-ConfigurationCommon`. Downlink symbols configured by `tdd-UL-DL-ConfigurationCommon` cannot be modified to uplink symbols by `tdd-UL-DL-ConfigurationDedicated`, and uplink symbols configured by `tdd-UL-DL-ConfigurationCommon` cannot be modified to downlink symbols by `tdd-UL-DL-ConfigurationDedicated`.

[0056] For example, a network device configures a pattern of time slot structure using tdd-UL-DL-ConfigurationCommon as shown in Figure 2. Based on this, the network device configures the time slot structure of two of the time slots using tdd-UL-DL-ConfigurationDedicated, as shown in Figure 3. Taking the two time slots configured by tdd-UL-DL-ConfigurationDedicated as time slot 1 and time slot 2 within a 5ms period as an example.

[0057] Based on the semi-static uplink / downlink configuration signaling for configuring the time slot structure, network devices can also dynamically indicate the time slot format for each time slot through a Slot Format Indicator (SFI). This SFI uses DCI format 2_0, and the Radio Network Temporary Identifier (RNTI) used for scrambling is SFI-RNTI. The dynamic SFI can only indicate the transmission direction of the flexible symbols configured in the semi-static uplink / downlink configuration signaling; it cannot change the transmission direction of the uplink or downlink symbols configured in the semi-static configuration signaling.

[0058] SFI can simultaneously indicate the slot format of multiple serving cells. Network devices can configure cell indexes and the position of the start bit of the corresponding slot format combination identifier (slotFormatCombinationId) in DCI format 2_0 via RRC signaling. The network device configures multiple slot format combinations (slotFormatCombination), each corresponding to an identifier (slotFormatCombinationId) and a set of slot format indicators. Each slot format indicator is used to indicate the slot format of one slot.

[0059] The SFI carries information including an SFI index, which corresponds to the slotFormatCombinationId. A set of time slot formats can be determined based on the SFI index. The time slot format indicated by the SFI applies to multiple consecutive time slots starting from the time slot carrying the SFI, and the number of time slots indicated by the SFI is greater than or equal to the monitoring period of the Physical Downlink Control Channel (PDCCH) carrying the SFI. If a time slot is indicated by two SFIs, the time slot format indicated by both SFIs should be identical.

[0060] When configuring the time slot format of a serving cell, network devices also configure a subcarrier spacing, namely the SFI reference subcarrier spacing μ. SFI μ SFI The subcarrier spacing μ of the serving cell for monitoring SFI is less than or equal to μ, i.e., μ ≥ μ SFI At this time, the time slot format of a time slot indicated by SFI is suitable for 2(μ-μ SFI ) consecutive time slots, and each downlink symbol indicated by SFI corresponds to 2(μ-μ SFI ) consecutive downlink symbols, each uplink symbol indicated by SFI corresponds to 2(μ-μ) SFI ) consecutive uplink symbols, each flexible symbol indicated by SFI corresponds to 2 (μ -μ SFI () A series of flexible symbols.

[0061] Figure 4 illustrates a schematic diagram of the slot format indicated by SFI according to an exemplary embodiment of this application. The ratio of downlink symbols, flexible symbols, and uplink symbols in a slot is DL:FL:UL = 4:7:3, meaning a slot includes 4 downlink symbols, 7 flexible symbols, and 3 uplink symbols. Furthermore, μSFI is configured as 0, corresponding to a subcarrier spacing of 15 kHz. This SFI is used to indicate the slot format of a Time Division Duplex (TDD) cell, and the corresponding subcarrier spacing μ = 1, meaning a subcarrier spacing of 30 kHz. Therefore, the slot format indicated by this SFI applies to two consecutive slots. One downlink symbol indicated by the SFI corresponds to two consecutive downlink symbols in the slot of that cell, one flexible symbol indicated by the SFI corresponds to two consecutive flexible symbols in the slot of that cell, and one uplink symbol indicated by the SFI corresponds to two consecutive uplink symbols in the slot of that cell.

[0062] Sub-band Full Duplex (SBFD) refers to a technology that allows simultaneous transmission and reception on different subbands within the same subframe, time slot, or symbol. It helps address issues such as weak uplink coverage, high uplink latency, and insufficient uplink capacity caused by limited uplink resource allocation. Optionally, SBFD technology may also be called Cross Division Duplex (XDD) technology.

[0063] As shown in Figure 5, network devices can semi-statically configure uplink sub-bands (UL Sub-bands) in the frequency domain resources corresponding to downlink symbols and flexible symbols. Furthermore, a guard band exists at the edge of the uplink sub-band. For downlink symbols (DL Symbols) configured with uplink sub-bands, such as symbol 2 and symbol 3, the network device can simultaneously perform uplink reception in the uplink sub-bands corresponding to symbol 2 and symbol 3, and downlink transmission in the downlink sub-bands (DL Sub-bands) corresponding to symbol 2 and symbol 3. The downlink sub-band refers to the downlink resources excluding the downlink sub-band and guard band. From the network device's perspective, it supports simultaneous uplink reception and downlink transmission in different frequency domain resources corresponding to the same time unit. However, for the UE, only half-duplex operation is possible in symbol 2 and symbol 3; that is, the UE can only transmit in the uplink sub-band corresponding to one time unit or receive in the downlink sub-band corresponding to one time unit. Therefore, SBFD technology can be considered primarily applied to the network device side.

[0064] For flexible symbols configured with uplink subbands, such as symbols 4-7, if symbols 4-7 are indicated as downlink symbols by the network device via tdd-UL-DL-ConfigurationDedicated or SFI, the network device can perform full-duplex operation in symbols 4-7, while the UE still performs half-duplex operation in symbols 4-7, referring to the behavior of the network device and UE in symbols 2 and 3. If symbols 4-7 are indicated as uplink symbols by the network device via tdd-UL-DL-ConfigurationDedicated or SFI, then symbols 4-7 are UL symbols, and the network device only performs uplink reception in symbols 4-7, and the UE only performs uplink transmission in symbols 4-7. The downlink symbols and flexible symbols configured with uplink subbands mentioned above can be called SBFD symbols. The DL symbols and flexible symbols configured with UL subbands mentioned above are called SBFD symbols.

[0065] In summary, the introduction of SBFD technology enables network devices to transmit and receive simultaneously in different subbands within a single carrier corresponding to an SBFD symbol, which differs from the half-duplex operation where network devices can only transmit or receive within a single carrier corresponding to a single symbol.

[0066] In the Release 19 (R19) version of SBFD technology, two types of UEs are defined: SBFD no-aware UEs and SBFD aware UEs. SBFD no-aware UEs cannot understand the aforementioned uplink subband configuration and can also be called legacy UEs. SBFD aware UEs, on the other hand, support receiving the aforementioned uplink subband configuration. Taking symbol 2 as an example, from the perspective of an SBFD aware UE, it understands that symbol 2 has both uplink and downlink subbands. An SBFD aware UE can transmit in the uplink subband corresponding to symbol 2 or receive in the downlink subband corresponding to symbol 2. From the perspective of an SBFD no-aware UE, it understands symbol 2 as a downlink symbol and will only perform downlink reception in symbol 2. Therefore, in symbol 2, the uplink transmission of an SBFD aware UE and the downlink reception of an SBFD no-aware UE may conflict and interfere with each other in the frequency domain resources corresponding to the uplink subband.

[0067] The purpose of defining SBFD no-aware UEs and SBFD aware UEs is to ensure backward compatibility of SBFD technology. That is, the introduction of SBFD technology should not affect the normal operation of SBFD no-aware UEs, i.e., legacy UEs. Therefore, when designing the working mechanism of SBFD technology, the flexible TDD time slot structure was still used, and SBFD symbols were introduced on top of the existing DL symbol / UL symbol / Flexible symbol. Obviously, this design makes the NR TDD system more complex. Therefore, when designing for future communication systems (such as 6G and its subsequent evolution systems), backward compatibility issues can be disregarded, assuming that all UEs in future communication systems have SBFD aware capability (i.e., support SBFD technology). Based on this, designing a simpler SBFD working mechanism is the problem that needs to be solved.

[0068] Figure 6 illustrates a flowchart of a resource configuration method provided in an exemplary embodiment of this application, which is applied to the wireless communication system shown in Figure 1. The method is executed by a network device and includes at least some of the following steps:

[0069] Step 620: The network device sends a first signaling message, which is used to configure a first time-frequency resource, including one or more of uplink resources, downlink resources and interval resources.

[0070] The first time-frequency resource may include uplink resources, downlink resources, both uplink and downlink resources, or uplink, downlink, and interval resources. If the first time-frequency resource includes interval resources, the interval resources are located between the uplink and downlink resources, which helps to avoid mutual interference between them. Uplink resources may also be called uplink sub-band (UL Sub-band), downlink resources may also be called downlink sub-band (DL Sub-band), and interval resources may also be called protection resources or guard band.

[0071] The network device supports uplink resource reception within the first time-frequency resource and downlink resource transmission within the first time-frequency resource.

[0072] In this embodiment of the application, the network device can be implemented as the network device 110 shown in FIG1.

[0073] In summary, the method provided in this application embodiment supports network devices in sending first signaling to configure first time-frequency resources. By adjusting uplink and downlink resources within the system through the first signaling, it helps network devices to perform uplink and downlink transmissions simultaneously and balance network load.

[0074] Figure 7 illustrates a flowchart of a resource configuration method provided in an exemplary embodiment of this application, which is applied to the wireless communication system shown in Figure 1. The method is executed by the UE and includes at least some of the following steps:

[0075] Step 720: The UE receives a first signaling message, which is used to configure a first time-frequency resource, which includes one or more of uplink resources, downlink resources and interval resources.

[0076] The first time-frequency resource may include uplink resources, downlink resources, both uplink and downlink resources, or uplink, downlink, and interval resources. If the first time-frequency resource includes interval resources, then the interval resources are located between the uplink and downlink resources, which helps to avoid mutual interference between them. Uplink resources can also be called uplink sub-bands, downlink resources can also be called downlink sub-bands, and interval resources can also be called protection resources or protection bands.

[0077] In this embodiment, the UE is an SBFD-aware UE, meaning the UE understands the configuration of the first signaling. However, this application does not exclude the possibility of an SBFD-unaware UE existing in the system, which might not understand the configuration of the first signaling. Furthermore, regardless of whether the UE is SBFD-aware or SBFD-unaware, it can only perform uplink transmission or downlink reception within the first time-frequency resource. In other words, regardless of whether the UE understands the configuration of the first signaling, the UE can only perform half-duplex communication within the first time-frequency resource.

[0078] In this embodiment of the application, the UE can be implemented as the terminal device 120 shown in FIG1.

[0079] In summary, the method provided in this application embodiment supports the UE to receive a first signaling to obtain the configuration of a first time-frequency resource. The first signaling can adjust the uplink and downlink resources in the system, which helps network devices to perform uplink and downlink transmissions simultaneously and balance the network load.

[0080] Furthermore, based on the embodiments shown in Figures 6 and 7, this application also provides a specific design for the configuration of the first signaling, as shown in the embodiments in Figures 8 and 9.

[0081] Figure 8 illustrates a flowchart of a resource configuration method provided in an exemplary embodiment of this application, which is applied to the wireless communication system shown in Figure 1. The method is executed by a network device and includes at least some of the following steps:

[0082] Step 820: The network device sends a first signaling message, which is used to configure a first time-frequency resource, including one or more of uplink resources, downlink resources and interval resources.

[0083] In some embodiments, the first signaling is cell-specific signaling. For example, the first signaling is System Information Block 1 (SIB1).

[0084] In some embodiments, the first signaling configures first time-frequency resources corresponding to different sub-carrier spacings (SCS). The frequency domain location information of the first time-frequency resources corresponding to different sub-carrier spacings is different, and / or the number of frequency domain elements of the first time-frequency resources corresponding to different sub-carrier spacings is different.

[0085] For example, the first signaling configuration specifies the mapping relationship between the SCS and the first time-frequency resource, with different SCSs corresponding to different first time-frequency resources. Another example is the mapping relationship between the first signaling configuration and the frequency domain location information and / or the number of frequency domain units of the first time-frequency resource, with different SCSs corresponding to different frequency domain location information and / or the number of frequency domain units of the first time-frequency resource.

[0086] The reason for supporting the configuration of first time-frequency resources corresponding to multiple SCSs in the first signaling is that the communication system may support multiple SCSs, such as 15kHz, 30kHz, 60kHz, and 120kHz. While the starting position of the Common Resource Block (CRB) 0 corresponding to different SCSs is the same, the starting positions of subsequent RBs and the total number of RBs within the bandwidth are different. Therefore, this application embodiment also supports configuring first time-frequency resources separately for different SCSs, with the first signaling including multiple sets of configuration parameters for the first time-frequency resources, and each set of configuration parameters for the first time-frequency resources being associated with a subcarrier spacing.

[0087] In some embodiments, the first signaling configures first time-frequency resources corresponding to different bandwidths. The frequency domain location information of the first time-frequency resources corresponding to different bandwidths is different, and / or the number of frequency domain units of the first time-frequency resources corresponding to different bandwidths is different.

[0088] For example, the mapping relationship between the first signaling configuration bandwidth and the first time-frequency resource, with different bandwidths corresponding to different first time-frequency resources. Another example is the mapping relationship between the first signaling configuration bandwidth and the frequency domain location information and / or the number of frequency domain units of the first time-frequency resource, with different bandwidths corresponding to different frequency domain location information and / or the number of frequency domain units of the first time-frequency resource.

[0089] In some embodiments, the first signaling configures the first time-frequency resources corresponding to different bandwidths and different SCSs. That is, the first signaling configures the mapping relationship between SCSs, bandwidths, and first time-frequency resources.

[0090] In some embodiments, the first signaling configures the frequency domain location information and / or the number of frequency domain units of the first time-frequency resource. Wherein:

[0091] • The number of frequency domain units in the first time-frequency resource includes one or more of the following: the number of frequency domain units included in the uplink resource, the number of frequency domain units included in the downlink resource, and the number of frequency domain units included in the interval resource.

[0092] In this embodiment, the frequency domain unit includes one or more of the following: Resource Block (RB), Physical Resource Block (PRB), Sub-band, Carrier, Bandwidth Part (BWP), Subcarrier, and Resource Element. Taking an RB as an example, the number of frequency domain units in the first time-frequency resource includes one or more of the following: the number of RBs in the uplink resource, the number of RBs in the downlink resource, and the number of RBs in the interval resource. Taking a sub-band as an example, the number of frequency domain units in the first time-frequency resource includes one or more of the following: the number of sub-bands in the uplink resource, the number of sub-bands in the downlink resource, and the number of sub-bands in the interval resource. The situation is similar for other types of frequency domain units, and will not be described in detail here.

[0093] • The frequency domain location information of the first time-frequency resource includes one or more of the following: the frequency domain start position of the uplink resource, the frequency domain end position of the uplink resource, the frequency domain start position of the downlink resource, the frequency domain end position of the downlink resource, the frequency domain start position of the interval resource, the frequency domain end position of the interval resource, the frequency domain interval between the downlink resource and the uplink resource, whether the uplink resource is located at the edge of the first time-frequency resource in the frequency domain, and whether the uplink resource is located in the middle of the first time-frequency resource in the frequency domain.

[0094] It should be emphasized that the first time-frequency resource may or may not include interval resources.

[0095] In some embodiments, the frequency domain location information of the first time-frequency resource indicates the location of the first time-frequency resource within the cell bandwidth. That is, the first time-frequency resource configured by the network device via the first signaling is relative to the entire cell bandwidth; the first signaling configures the relative position of the first time-frequency resource within the entire cell bandwidth. The cell bandwidth includes the bandwidth of one or more carriers associated with the cell where the network device is located, so the cell bandwidth can also be expressed as the cell carrier bandwidth. Multiple carriers associated with the cell where the network device is located may be adjacent or non-adjacent in the frequency domain. Further, the location of the first time-frequency resource within the cell bandwidth is referenced to the CRB, and the granularity of the frequency domain location is RB.

[0096] In some embodiments, the total bandwidth of the first time-frequency resource is equal to or less than the cell bandwidth. When the total bandwidth of the first time-frequency resource is equal to the cell bandwidth, no additional indication of the total bandwidth of the first time-frequency resource is required to save overhead. When the total bandwidth of the first time-frequency resource is less than the cell bandwidth, the first signaling also configures the total bandwidth of the first time-frequency resource.

[0097] In some embodiments, when the communication system has a bandwidth usage mode based on BWP, a first time-frequency resource and an activated BWP are used to determine a second time-frequency resource, which is used only for uplink transmission or only for downlink transmission. The second time-frequency resource is located in the overlapping portion of the first time-frequency resource and the activated BWP. For example, if a first signaling configures a first time-frequency resource for the UE, and the UE is configured with an activated BWP, then the second time-frequency resource actually used by the UE is the overlapping portion of the first time-frequency resource and the activated BWP. Since the activated BWP can only be used for uplink or downlink, the second time-frequency resource can also only be used for downlink transmission or only for downlink transmission. In this case, the first time-frequency resource can be considered as the resource configured by the network device for the UE, while the second time-frequency resource is the resource that the UE can actually use.

[0098] In some embodiments, the frequency domain location information of the first time-frequency resource indicates the location of the first time-frequency resource within a BWP. That is, the first time-frequency resource configured by the network device via first signaling is relative to the BWP, and the first signaling configures the relative location of the first time-frequency resource within a BWP. The BWP is located within the cell bandwidth, which includes the bandwidth of one or more carriers associated with the cell where the network device is located. The multiple carriers associated with the cell where the network device is located may be adjacent or non-adjacent in the frequency domain. Further, the location of the first time-frequency resource within the BWP is referenced to the frequency domain start position of the BWP, and the granularity of the frequency domain location is a PRB (Precision Frequency Block).

[0099] In some embodiments, the total bandwidth of the first time-frequency resource is equal to or less than the bandwidth of the BWP. When the total bandwidth of the first time-frequency resource is equal to the bandwidth of the BWP, no additional indication of the total bandwidth of the first time-frequency resource is required to save overhead. When the total bandwidth of the first time-frequency resource is less than the bandwidth of the BWP, the first signaling also configures the total bandwidth of the first time-frequency resource.

[0100] In some embodiments, a single time unit in the first time-frequency resource corresponds to only one uplink sub-band. However, it is not excluded that a single time unit in the first time-frequency resource may correspond to two or more uplink sub-bands. It is understood that the more uplink sub-bands there are, the more guard bands there will be, resulting in a waste of spectrum resources and a reduction in spectrum utilization. Furthermore, the introduction of multiple uplink sub-bands will also make the indication of frequency domain location more complex.

[0101] In the frequency domain, uplink resources may be located at the edge or the middle of the first time-frequency resource. As shown in Figure 9(a), the uplink resource is located in the middle of the cell bandwidth or BWP in the frequency domain. Therefore, a single time unit in the first time-frequency resource corresponds to one uplink sub-band and two downlink sub-bands, and correspondingly, there may also be two guard bands. As shown in Figure 9(b), the uplink resource is located at the upper edge of the cell bandwidth or BWP in the frequency domain. Therefore, a single time unit in the first time-frequency resource corresponds to one uplink sub-band and one downlink sub-band, and correspondingly, there may also be one guard band. As shown in Figure 9(c), the uplink resource is located at the lower edge of the cell bandwidth or BWP in the frequency domain. Therefore, a single time unit in the first time-frequency resource corresponds to one uplink sub-band and one downlink sub-band, and correspondingly, there may also be one guard band. Whether the uplink resource is located at the edge or the middle of the first time-frequency resource in the frequency domain can be determined by the communication protocol, the network device configuration, or the UE.

[0102] In some embodiments, the first signaling includes a first indication field for indicating whether the uplink resource is located in the edge or middle portion of the first time-frequency resource in the frequency domain. For example, when the first indication field is a first value, it indicates that the uplink resource is located in the middle portion of the first time-frequency resource in the frequency domain, and when the first indication field is a second value, it indicates that the uplink resource is located in the edge portion of the first time-frequency resource in the frequency domain.

[0103] In some embodiments, the first signaling includes a second indication field for indicating the number of downlink subbands corresponding to a single time unit in the first time-frequency resource. For example, the second indication field indicates that a single time unit corresponds to one or two downlink subbands.

[0104] In some embodiments, the first signaling includes a first indication field and a second indication field. The first indication field is used to indicate whether the uplink resource is located in the edge or middle portion of the first time-frequency resource in the frequency domain. The second indication field is used to indicate the number of downlink sub-bands corresponding to a single time unit in the first time-frequency resource.

[0105] In some embodiments, the first signaling configuration includes one or more of the following: the frequency domain start position of the uplink resource, the frequency domain end position of the uplink resource, the frequency domain start position of the downlink resource, the frequency domain end position of the downlink resource, the frequency domain start position of the interval resource, and the frequency domain end position of the interval resource. After receiving the first signaling, the UE determines, based on the configuration of the first signaling, whether the uplink resource is located at the edge of the first time-frequency resource in the frequency domain, and / or determines the number of downlink sub-bands corresponding to a single time unit.

[0106] In some embodiments, the frequency domain location information and the number of frequency domain cells of the first time-frequency resource are represented by a Resource Indication Value (RIV). Each RIV corresponds to a starting RB index. start and the number of consecutive CRBs L CRBs , refer to formula (1). RIV=N RB (L CRBs -1)+RB start else RIV=N RB (N RB -L CRBs +1)+(N RB -1-RB start )

[0107] in, Indicates rounding down, N RB This represents the total number of RBs. If the frequency domain location of the first time-frequency resource indicated by the first signaling is the location of the first time-frequency resource in the cell bandwidth, then N RB This represents the total number of RBs within the cell bandwidth. If the frequency domain location of the first time-frequency resource indicated by the first signaling is the location of the first time-frequency resource in the BWP, then N RB This represents the total number of RBs within BWP.

[0108] For example, the first signaling configuration includes one or more of the following: a first RIV, a second RIV, and the number of frequency domain elements included in the interval resource. The first RIV indicates the frequency domain start position and the number of frequency domain elements of the downlink resource; therefore, the UE can determine the frequency domain start position and the number of frequency domain elements of the downlink resource based on the first RIV configured in the first signaling. The second RIV indicates the frequency domain start position and the number of frequency domain elements of the uplink resource; therefore, the UE can determine the frequency domain start position and the number of frequency domain elements of the uplink resource based on the second RIV configured in the first signaling.

[0109] In some embodiments, the first time-frequency resource includes one or more time units. The uplink resources, downlink resources, and interval resources corresponding to different time units are different, or the uplink resources, downlink resources, and interval resources corresponding to different time units are the same. Referring to FIG9, the frequency domain location and bandwidth of the uplink sub-band, downlink sub-band, and guard band are the same in each time unit. In this embodiment, the time unit includes one or more of the following: symbol, symbol group, time slot, sub-time slot, subframe, and frame. For example, the first time-frequency resource includes one or more time slots, and the uplink resources, downlink resources, and interval resources corresponding to different time slots may be the same or different. If the uplink resources, downlink resources, and interval resources corresponding to different time units are the same, it means that the configuration of the first signaling applies to all time units within the first time-frequency resource.

[0110] In some embodiments, the first signaling configures the period of the first time-frequency resource. For example, if the first signaling configures the period of the first time-frequency resource to be P, then the first time-frequency resource repeats in the time domain with a period of P.

[0111] In some embodiments, the first signaling configures the time-domain location information and the number of time units of the first time-frequency resource. The time-domain location information of the first time-frequency resource includes at least one of the following: the time-domain start position of the first time-frequency resource, the time-domain end position of the first time-frequency resource, and the index of one or more time units included in the first time-frequency resource.

[0112] In some embodiments, the first signaling configures the period and time-domain location information of the first time-frequency resource.

[0113] For example, the first signaling configures the start and end timeslots of the first time-frequency resource. The first time-frequency resource includes the start timeslot, the end timeslot, and all timeslots in between, and is continuous in the time domain. As shown in Figure 10(a), assuming the period P of the first time-frequency resource is 5ms and the SCS is 15kHz, one period includes 5 timeslots. The first signaling configures the start timeslot index of the first time-frequency resource as 1 and the end timeslot index as 3, then the first time-frequency resource includes timeslot 1, timeslot 2, and timeslot 3.

[0114] For example, the first signaling configures the start and end symbols of the first time-frequency resource. The first time-frequency resource includes the start symbol, the end symbol, and all orthogonal frequency division multiplexing (OFDM) symbols between them. The first time-frequency resource is continuous in the time domain. As shown in Figure 10(b), assuming the period P of the first time-frequency resource is 5ms and the SCS is 15kHz, one period includes 5 time slots. The first signaling configures the start time slot index of the first time-frequency resource to be 1 and the start symbol index to be 3, and the end time slot index to be 3 and the end symbol index to be 6. Then, the frequency domain start position of the first time-frequency resource is symbol 3 of time slot 1, and the frequency domain end position is symbol 6 of time slot 3.

[0115] For example, the first signaling configuration includes time unit indices for the first time-frequency resource. The time unit indices configured in the first signaling can be continuous or discontinuous; that is, the first time-frequency resource can be continuous or discontinuous in the time domain. Referring to Figure 10, if the time slot indices configured in the first signaling include 1, 2, and 3, it indicates that the first time-frequency resource includes time slot 1, time slot 2, and time slot 3. If the time slot indices configured in the first signaling include 1, 2, and 4, it indicates that the first time-frequency resource includes time slot 1, time slot 2, and time slot 4.

[0116] In some embodiments, the first time-frequency resource includes all time units within the system. The uplink resources, downlink resources, and interval resources corresponding to different time units are the same, or the uplink resources, downlink resources, and interval resources corresponding to different time units are different. If the uplink resources, downlink resources, and interval resources corresponding to different time units are the same, it means that the configuration of the first signaling applies to all time units within the first time-frequency resource. For example, the first time-frequency resource includes all time slots within the system, and the uplink resources, downlink resources, and interval resources corresponding to different time slots are the same or different. In this case, the network device only needs to configure the frequency domain location information and / or the number of frequency domain units of the first time-frequency resource through the first signaling. The location of the time domain resources within the first time-frequency resource does not need to be configured by the first signaling. The UE defaults to all time slots belonging to the first time-frequency resource; for example, the UE defaults to all time slots corresponding to frequency domain resources including uplink and downlink resources.

[0117] In some embodiments, the first signaling configures the transmission direction of the first time-frequency resource, and the transmission directions corresponding to different time units included in the first time-frequency resource may be the same or different.

[0118] In some embodiments, the first signaling configures the transmission direction of at least one frequency domain unit included in the first time-frequency resource, and the transmission directions of the frequency domain units corresponding to different time units included in the first time-frequency resource may be the same or different. For example, the first signaling configures the transmission direction of at least one sub-band included in the first time-frequency resource, and the transmission directions of the sub-bands corresponding to different time units included in the first time-frequency resource may be the same or different.

[0119] Taking the example that the transmission directions of the sub-bands corresponding to different time units of the first time-frequency resource are different, the first signaling needs to configure the transmission direction of the first time-frequency resource in addition to configuring the frequency domain position of the first time-frequency resource. For example, the first time-frequency resource includes a first resource and a second resource, and the first signaling configures the transmission direction for the first resource and the second resource corresponding to different time units.

[0120] As shown in Figure 11, downlink time slots, uplink time slots, and flexible time slots can be determined based on the TDD time slot structure configuration information. Assuming the first signaling is configured with RIV, the UE can determine the first resource and the second resource based on the RIV. In the downlink time slot and / or flexible time slot, the transmission direction of the first resource is downlink, and the transmission direction of the second resource is uplink. In the uplink time slot, the transmission direction of the first resource is uplink, and the transmission direction of the second transmission resource is downlink. In this way, the first signaling only needs to configure one set of frequency domain location information, instead of configuring multiple sets of frequency domain location information for multiple time slots. In some embodiments, the aforementioned time slots can be replaced with symbols. For example, in the downlink symbol and / or flexible symbol, the transmission direction of the first resource is downlink, and the transmission direction of the second resource is uplink; in the uplink symbol, the transmission direction of the first resource is uplink, and the transmission direction of the second transmission resource is downlink.

[0121] Step 840: The network device sends a second signaling message, which is used to update or modify the first time-frequency resource.

[0122] In some embodiments, the second signaling is UE-specific signaling; for example, the second signaling is RRC signaling.

[0123] In some embodiments, the second signaling is used to configure one or more of the following: new frequency domain location information of the first time-frequency resource (i.e., the frequency domain location information of the updated or modified first time-frequency resource); new number of frequency domain units of the first time-frequency resource (i.e., the number of frequency domain units of the updated or modified first time-frequency resource); new number of time units of the first time-frequency resource (i.e., the number of time units of the updated or modified first time-frequency resource); new period of the first time-frequency resource (i.e., the period of the updated or modified first time-frequency resource); new transmission direction of the first time-frequency resource (i.e., the transmission direction of the updated or modified first time-frequency resource); and new pattern of the first time-frequency resource (i.e., the pattern of the updated or modified first time-frequency resource). Specific details of each item can be found in the relevant content of step 820, and will not be repeated here.

[0124] In some embodiments, the second signaling configuration includes one or more of the following: a third RIV, a fourth RIV, and the number of new frequency domain elements included in the interval resource (i.e., the number of frequency domain elements in the updated or modified interval resource). The third RIV indicates the new frequency domain start position and the number of new frequency domain elements of the downlink resource; therefore, the UE can determine the frequency domain start position and the number of frequency domain elements of the updated or modified downlink resource based on the third RIV configured in the second signaling. The fourth RIV indicates the new frequency domain start position and the number of new frequency domain elements of the uplink resource; therefore, the UE can determine the frequency domain start position and the number of frequency domain elements of the updated or modified uplink resource based on the fourth RIV configured in the second signaling.

[0125] In some embodiments, the second signaling only updates or modifies a portion of the resources in the first time-frequency resource. For example, the second signaling only updates or modifies the frequency domain resources (including the frequency domain start position and / or frequency domain end position and / or the number of frequency domain units) corresponding to a portion of the time units in the first time-frequency resource. For example, the second signaling only updates or modifies the frequency domain resources corresponding to the flexible time slots in the first time-frequency resource. For example, the second signaling only updates or modifies the frequency domain resources corresponding to the flexible symbols in the first time-frequency resource. For example, the second signaling only updates or modifies the flexible sub-bands (including the frequency domain start position and / or frequency domain end position and / or the number of frequency domain units and / or the transmission direction) corresponding to the flexible time slots in the first time-frequency resource. For example, the second signaling only updates or modifies the flexible sub-bands corresponding to the flexible symbols in the first time-frequency resource.

[0126] It should be emphasized that step 840 is an optional step.

[0127] Step 860: The network device receives uplink signals in the uplink resources within the first time-frequency resource and sends downlink signals in the downlink resources within the first time-frequency resource.

[0128] Network devices can perform full-duplex communication on the first time-frequency resource, enabling simultaneous transmission and reception within that resource. Uplink signals may include uplink data, and downlink signals may include downlink data. Step 860 is optional.

[0129] Other related content can be found in step 620, and will not be repeated here.

[0130] In summary, the method provided in this application supports network devices sending first signaling to semi-statically configure first time-frequency resources, which simultaneously support uplink and downlink transmission. The semi-static configuration of the first signaling facilitates SBFD technology, enabling dynamic balancing of network load and reducing resource conflicts and congestion. Furthermore, it also supports network devices sending second signaling to update or modify the configuration of the first signaling, facilitating flexible configuration of transmission resources within the system.

[0131] Figure 12 shows a flowchart of a resource configuration method provided in an exemplary embodiment of this application, which is applied to the wireless communication system shown in Figure 1. The method is executed by the UE and includes at least some of the following steps:

[0132] Step 1220: The UE receives a first signaling message, which is used to configure a first time-frequency resource, which includes one or more of uplink resources, downlink resources and interval resources.

[0133] In some embodiments, the first signaling is cell-specific signaling. For example, the first signaling is SIB1.

[0134] In some embodiments, the first signaling configures the first time-frequency resources corresponding to different SCSs. Specifically, the frequency domain location information of the first time-frequency resources corresponding to different subcarrier intervals is different, and / or, the number of frequency domain elements of the first time-frequency resources corresponding to different subcarrier intervals is different.

[0135] In some embodiments, the first signaling configures first time-frequency resources corresponding to different bandwidths. The frequency domain location information of the first time-frequency resources corresponding to different bandwidths is different, and / or the number of frequency domain units of the first time-frequency resources corresponding to different bandwidths is different.

[0136] In some embodiments, the first signaling configures the first time-frequency resources corresponding to different bandwidths and different SCSs. That is, the first signaling configures the mapping relationship between SCSs, bandwidths, and first time-frequency resources.

[0137] In some embodiments, the first signaling configures the frequency domain location information and / or the number of frequency domain units of the first time-frequency resource. Wherein:

[0138] • The number of frequency domain units in the first time-frequency resource includes one or more of the following: the number of frequency domain units included in the uplink resource, the number of frequency domain units included in the downlink resource, and the number of frequency domain units included in the interval resource.

[0139] Taking frequency domain units including RBs as an example, the number of frequency domain units in the first time-frequency resource includes one or more of the following: the number of RBs in the uplink resource, the number of RBs in the downlink resource, and the number of RBs in the interval resource. Taking frequency domain units including subbands as an example, the number of frequency domain units in the first time-frequency resource includes one or more of the following: the number of subbands in the uplink resource, the number of subbands in the downlink resource, and the number of subbands in the interval resource. The cases where frequency domain units are of other types are similar and will not be elaborated further.

[0140] • The frequency domain location information of the first time-frequency resource includes one or more of the following: the frequency domain start position of the uplink resource, the frequency domain end position of the uplink resource, the frequency domain start position of the downlink resource, the frequency domain end position of the downlink resource, the frequency domain start position of the interval resource, the frequency domain end position of the interval resource, the frequency domain interval between the downlink resource and the uplink resource, whether the uplink resource is located at the edge of the first time-frequency resource in the frequency domain, and whether the uplink resource is located in the middle of the first time-frequency resource in the frequency domain.

[0141] It should be emphasized that the first time-frequency resource may or may not include interval resources.

[0142] In some embodiments, the frequency domain location information of the first time-frequency resource indicates the location of the first time-frequency resource within the cell bandwidth. That is, the first time-frequency resource configured by the network device via the first signaling is relative to the entire cell bandwidth; the first signaling configures the relative position of the first time-frequency resource within the entire cell bandwidth. The cell bandwidth includes the bandwidth of one or more carriers associated with the cell where the network device is located, so the cell bandwidth can also be expressed as the cell carrier bandwidth. Multiple carriers associated with the cell where the network device is located may be adjacent or non-adjacent in the frequency domain. Further, the location of the first time-frequency resource within the cell bandwidth is referenced to the CRB, and the granularity of the frequency domain location is RB.

[0143] In some embodiments, the total bandwidth of the first time-frequency resource is equal to or less than the cell bandwidth. When the total bandwidth of the first time-frequency resource is equal to the cell bandwidth, no additional indication of the total bandwidth of the first time-frequency resource is required to save overhead. When the total bandwidth of the first time-frequency resource is less than the cell bandwidth, the first signaling also configures the total bandwidth of the first time-frequency resource.

[0144] In some embodiments, a first time-frequency resource and an active BWP are used to determine a second time-frequency resource, which is used only for uplink transmission or only for downlink transmission. The second time-frequency resource is located in the overlapping portion of the first time-frequency resource and the active BWP. For example, a first signaling configures the first time-frequency resource for the UE, and the second time-frequency resource actually used by the UE is the overlapping portion of the first time-frequency resource and the active BWP. Since the active BWP can only be used for uplink or downlink, the second time-frequency resource can also only be used for downlink transmission or only for downlink transmission.

[0145] In some embodiments, the frequency domain location information of the first time-frequency resource indicates the location of the first time-frequency resource within a BWP. That is, the first time-frequency resource configured by the network device via first signaling is relative to the BWP, and the first signaling configures the relative location of the first time-frequency resource within a BWP. The BWP is located within the cell bandwidth, which includes the bandwidth of one or more carriers associated with the cell where the network device is located. The multiple carriers associated with the cell where the network device is located may be adjacent or non-adjacent in the frequency domain. Further, the location of the first time-frequency resource within the BWP is referenced to the frequency domain start position of the BWP, and the granularity of the frequency domain location is a PRB (Precision Frequency Block).

[0146] In some embodiments, the total bandwidth of the first time-frequency resource is equal to or less than the bandwidth of the BWP. When the total bandwidth of the first time-frequency resource is equal to the bandwidth of the BWP, no additional indication of the total bandwidth of the first time-frequency resource is required to save overhead. When the total bandwidth of the first time-frequency resource is less than the bandwidth of the BWP, the first signaling also configures the total bandwidth of the first time-frequency resource.

[0147] In some embodiments, a single time unit in the first time-frequency resource corresponds to only one uplink sub-band. However, it is not excluded that a single time unit in the first time-frequency resource may correspond to two or more uplink sub-bands. It is understood that the more uplink sub-bands there are, the more guard bands there will be, resulting in a waste of spectrum resources and a reduction in spectrum utilization. Furthermore, the introduction of multiple uplink sub-bands will also make the indication of frequency domain location more complex.

[0148] The uplink resource may be located at the edge of the first time-frequency resource or in the middle of the first time-frequency resource in the frequency domain. See Figure 9 for reference.

[0149] In some embodiments, the first signaling includes a first indication field for indicating whether the uplink resource is located in the edge or middle portion of the first time-frequency resource in the frequency domain. For example, when the first indication field is a first value, it indicates that the uplink resource is located in the middle portion of the first time-frequency resource in the frequency domain, and when the first indication field is a second value, it indicates that the uplink resource is located in the edge portion of the first time-frequency resource in the frequency domain.

[0150] In some embodiments, the first signaling includes a second indication field for indicating the number of downlink subbands corresponding to a single time unit in the first time-frequency resource. For example, the second indication field indicates that a single time unit corresponds to one or two downlink subbands.

[0151] In some embodiments, the first signaling includes a first indication field and a second indication field. The first indication field is used to indicate whether the uplink resource is located in the edge or middle portion of the first time-frequency resource in the frequency domain. The second indication field is used to indicate the number of downlink sub-bands corresponding to a single time unit in the first time-frequency resource.

[0152] In some embodiments, the first signaling configuration includes one or more of the following: the frequency domain start position of the uplink resource, the frequency domain end position of the uplink resource, the frequency domain start position of the downlink resource, the frequency domain end position of the downlink resource, the frequency domain start position of the interval resource, and the frequency domain end position of the interval resource. After receiving the first signaling, the UE determines, based on the configuration of the first signaling, whether the uplink resource is located at the edge of the first time-frequency resource in the frequency domain, and / or determines the number of downlink sub-bands corresponding to a single time unit.

[0153] In some embodiments, the frequency domain location information and the number of frequency domain units of the first time-frequency resource are represented by RIV. The RIV calculation method is referenced in equation (1).

[0154] For example, the first signaling configuration includes one or more of the following: a first RIV, a second RIV, and the number of frequency domain elements included in the interval resource. The first RIV indicates the frequency domain start position and the number of frequency domain elements of the downlink resource; therefore, the UE can determine the frequency domain start position and the number of frequency domain elements of the downlink resource based on the first RIV configured in the first signaling. The second RIV indicates the frequency domain start position and the number of frequency domain elements of the uplink resource; therefore, the UE can determine the frequency domain start position and the number of frequency domain elements of the uplink resource based on the second RIV configured in the first signaling.

[0155] In some embodiments, the first time-frequency resource includes one or more time units. Different time units correspond to different uplink resources, downlink resources, and interval resources, or different time units correspond to the same uplink resources, downlink resources, and interval resources. If different time units correspond to the same uplink resources, downlink resources, and interval resources, it means that the configuration of the first signaling applies to all time units within the first time-frequency resource.

[0156] In some embodiments, the first signaling configures the period of the first time-frequency resource. For example, if the first signaling configures the period of the first time-frequency resource to be P, then the first time-frequency resource repeats in the time domain with a period of P.

[0157] In some embodiments, the first signaling configures the time-domain location information and the number of time units of the first time-frequency resource. The time-domain location information of the first time-frequency resource includes at least one of the following: the time-domain start position of the first time-frequency resource, the time-domain end position of the first time-frequency resource, and the index of one or more time units included in the first time-frequency resource.

[0158] In some embodiments, the first signaling configures the period and time-domain location information of the first time-frequency resource.

[0159] In some embodiments, the first time-frequency resource includes all time units within the system. The uplink resources, downlink resources, and interval resources corresponding to different time units are the same, or the uplink resources, downlink resources, and interval resources corresponding to different time units are different. If the uplink resources, downlink resources, and interval resources corresponding to different time units are the same, it means that the configuration of the first signaling applies to all time units within the first time-frequency resource. In this case, the network device only needs to configure the frequency domain location information and / or the number of frequency domain units of the first time-frequency resource through the first signaling. The location of the time domain resources within the first time-frequency resource does not need to be configured by the first signaling. The UE defaults to all time slots belonging to the first time-frequency resource; for example, the UE defaults to all time slots corresponding to frequency domain resources including both uplink and downlink resources.

[0160] In some embodiments, the first signaling configures the transmission direction of the first time-frequency resource, and the transmission directions corresponding to different time units included in the first time-frequency resource may be the same or different.

[0161] In some embodiments, the first signaling configures the transmission direction of at least one frequency domain unit included in the first time-frequency resource, and the transmission directions of the frequency domain units corresponding to different time units included in the first time-frequency resource may be the same or different. For example, the first signaling configures the transmission direction of at least one sub-band included in the first time-frequency resource, and the transmission directions of the sub-bands corresponding to different time units included in the first time-frequency resource may be the same or different.

[0162] Taking the example that the transmission directions of the sub-bands corresponding to different time units of the first time-frequency resource are different, the first signaling needs to configure the transmission direction of the first time-frequency resource in addition to configuring the frequency domain position of the first time-frequency resource. For example, the first time-frequency resource includes a first resource and a second resource, and the first signaling configures the transmission direction for the first resource and the second resource corresponding to different time units.

[0163] For other details, please refer to step 820; they will not be repeated here.

[0164] Step 1240: The UE receives a second signaling message, which is used to update or modify the first time-frequency resource.

[0165] In some embodiments, the second signaling is UE-specific signaling; for example, the second signaling is RRC signaling.

[0166] In some embodiments, the second signaling is used to configure one or more of the following: new frequency domain location information of the first time-frequency resource (i.e., the frequency domain location information of the updated or modified first time-frequency resource); new number of frequency domain units of the first time-frequency resource (i.e., the number of frequency domain units of the updated or modified first time-frequency resource); new number of time units of the first time-frequency resource (i.e., the number of time units of the updated or modified first time-frequency resource); new period of the first time-frequency resource (i.e., the period of the updated or modified first time-frequency resource); new transmission direction of the first time-frequency resource (i.e., the transmission direction of the updated or modified first time-frequency resource); and new pattern of the first time-frequency resource (i.e., the pattern of the updated or modified first time-frequency resource). Specific details of each item can be found in the relevant content of step 820, and will not be repeated here.

[0167] In some embodiments, the second signaling configuration includes one or more of the following: a third RIV, a fourth RIV, and the number of new frequency domain elements included in the interval resource (i.e., the number of frequency domain elements in the updated or modified interval resource). The third RIV indicates the new frequency domain start position and the number of new frequency domain elements of the downlink resource; therefore, the UE can determine the frequency domain start position and the number of frequency domain elements of the updated or modified downlink resource based on the third RIV configured in the second signaling. The fourth RIV indicates the new frequency domain start position and the number of new frequency domain elements of the uplink resource; therefore, the UE can determine the frequency domain start position and the number of frequency domain elements of the updated or modified uplink resource based on the fourth RIV configured in the second signaling.

[0168] In some embodiments, the second signaling only updates or modifies a portion of the resources in the first time-frequency resource. For example, the second signaling only updates or modifies the frequency domain resources (including the frequency domain start position and / or frequency domain end position and / or the number of frequency domain units) corresponding to a portion of the time units in the first time-frequency resource. For example, the second signaling only updates or modifies the frequency domain resources corresponding to the flexible time slots in the first time-frequency resource. For example, the second signaling only updates or modifies the frequency domain resources corresponding to the flexible symbols in the first time-frequency resource. For example, the second signaling only updates or modifies the flexible sub-bands (including the frequency domain start position and / or frequency domain end position and / or the number of frequency domain units and / or the transmission direction) corresponding to the flexible time slots in the first time-frequency resource. For example, the second signaling only updates or modifies the flexible sub-bands corresponding to the flexible symbols in the first time-frequency resource.

[0169] In some embodiments, the UE updates or modifies the first time-frequency resource configured by the first signaling based on the received second signaling.

[0170] It should be emphasized that step 1240 is an optional step.

[0171] Step 1260a: The UE sends an uplink signal using the uplink resources within the first time-frequency resource.

[0172] Step 1260b: The UE receives downlink signals using downlink resources within the first time-frequency resource.

[0173] Steps 1260a and 1260b are optional, and the UE cannot perform steps 1260a and 1260b simultaneously. The UE performs half-duplex communication on the first time-frequency resource. Uplink signals include, for example, uplink data, and downlink signals include, for example, downlink data.

[0174] Other related content can be found in step 720, and will not be repeated here.

[0175] In summary, the method provided in this application embodiment allows the UE to receive a first signaling message to obtain a semi-static configuration of a first time-frequency resource. The semi-static configuration of the first signaling message facilitates the implementation of SBFD technology, enabling dynamic balancing of network load and reducing resource conflicts and congestion. Furthermore, it also supports the UE receiving a second signaling message to update or modify the configuration of the first signaling message, facilitating flexible configuration of transmission resources within the system.

[0176] Figure 13 illustrates a schematic diagram of a first time-frequency resource provided in an exemplary embodiment of this application. The first signaling indicates the frequency domain location of the downlink resource and the frequency domain location of the uplink resource. After the frequency domain locations of the downlink and uplink resources are determined, the frequency domain location of the interval resource is also determined. The frequency domain locations of the downlink and uplink resources are indicated by the RIV. The network device can determine an RIV value based on the frequency domain start position and bandwidth (i.e., the number of RBs included) of any resource. For example, if the network device determines a first RIV based on the frequency domain start position and bandwidth of the downlink resource, and a second RIV based on the frequency domain start position and bandwidth of the uplink resource, then the first signaling includes the aforementioned first RIV and second RIV.

[0177] As mentioned above, the uplink sub-band can be located in the middle or edge of the first time-frequency resource in the frequency domain. Correspondingly, the number of downlink sub-bands can be two or one. Therefore, the first signaling may include one or two first RIVs, each indicating the frequency domain location and bandwidth of a downlink sub-band.

[0178] As shown in Figure 13, assume the total bandwidth of the first time-frequency resource includes 12 RBs. The uplink sub-band, located in the middle of the first time-frequency resource in the frequency domain, comprises 3 RBs. The first time-frequency resource includes two downlink sub-bands: the first downlink sub-band comprises 4 RBs, and the second downlink sub-band comprises 3 RBs. Based on the frequency domain start position (denoted as start position 1) and bandwidth (denoted as bandwidth 1) of the first downlink sub-band, RIV1 can be determined. Based on the frequency domain start position (denoted as start position 3) and bandwidth (denoted as bandwidth 3) of the second downlink sub-band, RIV3 can be determined. RIV1 and RIV3 are the two first RIVs. Based on the frequency domain start position (denoted as start position 2) and bandwidth (denoted as bandwidth 2) of the uplink sub-band, RIV2 can be determined. RIV2 is the second RIV. Furthermore, the RIV indication is referenced to the CRB.

[0179] After receiving the first signaling, the UE can determine the frequency domain location and number of RBs for the two downlink sub-bands based on RIV1 and RIV3, and determine the frequency domain location and number of RBs for the uplink sub-band based on RIV2. After determining the frequency domain locations of the uplink and downlink sub-bands, the frequency domain location of the guard band is also determined. The remaining resources within the first time-frequency resource, excluding the uplink and downlink sub-bands, constitute the guard band.

[0180] Figure 14 illustrates a schematic diagram of a first time-frequency resource provided in an exemplary embodiment of this application. The first signaling indicates the frequency domain location of the uplink resource and the frequency domain location or number of frequency domain units of the interval resource. Since the interval resource is adjacent to the uplink resource and is located between the uplink and downlink resources, the frequency domain location of the interval resource can be determined after determining the frequency domain location of the uplink resource and the number of frequency domain units of the interval resource. After the frequency domain locations of the uplink resource and the interval resource are determined, the frequency domain location of the downlink resource is also determined. The frequency domain locations of the uplink resource and the interval resource are indicated by the RIV. The network device can determine an RIV value based on the frequency domain start location and bandwidth (i.e., the number of RBs included) of any resource. For example, if the network device determines a second RIV based on the frequency domain start location and bandwidth of the uplink resource, and determines the number of RBs M of the interval resource based on the bandwidth of the interval resource, then the first signaling includes the aforementioned second RIV and the number of RBs M of the interval resource.

[0181] As shown in Figure 14, assuming the total bandwidth of the first time-frequency resource includes 12 RBs, the uplink sub-band is located in the middle of the first time-frequency resource in the frequency domain, comprising 3 RBs, and a guard band comprising 1 RB, i.e., M=1. The guard band is adjacent to the uplink sub-band, with one guard band on each side of the uplink sub-band in the frequency domain. Based on the frequency domain start position (denoted as start position2) and bandwidth (denoted as bandwidth2) of the uplink sub-band, RIV2 can be determined; RIV2 is the second RIV. The first signaling configuration sets RIV2 and M to 1. Furthermore, the RIV indication is referenced to the CRB.

[0182] After receiving the first signaling, the UE can determine the frequency domain location and number of RBs of the uplink sub-band based on RIV2, and determine the frequency domain location of the guard band based on the M value. After determining the frequency domain locations of the uplink sub-band and guard band, the frequency domain location of the downlink sub-band is also determined. The remaining resources in the first time-frequency resource, excluding the uplink sub-band and guard band, constitute the downlink sub-band.

[0183] Figure 15 illustrates a schematic diagram of a first time-frequency resource provided in an exemplary embodiment of this application. The first signaling indicates the frequency domain location of the downlink resource and the frequency domain location or number of frequency domain units of the interval resource. Since the interval resource is adjacent to the downlink resource and is located between the downlink and uplink resources, the frequency domain location of the interval resource can be determined after determining the frequency domain location of the downlink resource and the number of frequency domain units of the interval resource. After the frequency domain locations of the downlink resource and the interval resource are determined, the frequency domain location of the uplink resource is also determined. The frequency domain locations of the downlink resource and the interval resource are indicated by the RIV. The network device can determine an RIV value based on the frequency domain start location and bandwidth (i.e., the number of RBs included) of any resource. For example, if the network device determines the first RIV based on the frequency domain start location and bandwidth of the downlink resource, and determines the number of RBs M of the interval resource based on the bandwidth of the interval resource, then the first signaling includes the aforementioned first RIV and the number of RBs M of the interval resource.

[0184] As shown in Figure 15(a), assume the total bandwidth of the first time-frequency resource includes 12 RBs and two downlink sub-bands. The downlink sub-bands are located at the edge of the first time-frequency resource in the frequency domain. The first downlink sub-band includes 4 RBs, the second downlink sub-band includes 3 RBs, and a guard band includes 1 RB, i.e., M=1. The guard band is adjacent to the downlink sub-bands. RIV1 can be determined based on the frequency domain start position (denoted as start position1) and bandwidth (denoted as bandwidth1) of the first downlink sub-band. RIV3 can be determined based on the frequency domain start position (denoted as start position3) and bandwidth (denoted as bandwidth3) of the second downlink sub-band. RIV1 and RIV3 are the two first RIVs. The first signaling configuration sets RIV1, RIV3, and M to 1. Furthermore, the RIV indication is referenced to the CRB.

[0185] After receiving the first signaling, the UE can determine the frequency domain location and number of RBs for the first downlink sub-band based on RIV1, determine the frequency domain location and number of RBs for the second downlink sub-band based on RIV3, and determine the frequency domain location of the guard band based on the M value. After determining the frequency domain locations of the downlink sub-band and guard band, the frequency domain location of the uplink sub-band is also determined. The remaining resources within the first time-frequency resources, excluding the downlink sub-band and guard band, constitute the uplink sub-band.

[0186] As shown in Figure 15(b), assume the total bandwidth of the first time-frequency resource includes 12 RBs and one downlink sub-band, where the downlink sub-band includes 6 RBs and a guard band includes 1 RB, i.e., M=1. The guard band is adjacent to the downlink sub-band. Based on the frequency domain start position (denoted as start position4) and bandwidth (denoted as bandwidth4) of the downlink sub-band, RIV4 can be determined; RIV4 is the first RIV. The first signaling configuration sets RIV4 and M to 1. Furthermore, the RIV indication is referenced to the CRB.

[0187] After receiving the first signaling, the UE can determine the frequency domain location and number of RBs of the downlink sub-band based on RIV4, and determine the frequency domain location of the guard band based on the M value. After determining the frequency domain locations of the downlink sub-band and guard band, the frequency domain location of the uplink sub-band is also determined. The remaining resources in the first time-frequency resource, excluding the downlink sub-band and guard band, constitute the uplink sub-band.
