[0047] 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.

[0048] 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).

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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 .

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] `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`.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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 slot format of a slot indicated by SFI is applicable to 2. (μ-μ SFI () consecutive time slots, and each downlink symbol indicated by SFI corresponds to A series of consecutive downlink symbols, each uplink symbol indicated by SFI corresponds to A series of consecutive uplink symbols, each flexible symbol indicated by SFI corresponds to A series of flexible symbols.

[0063] Figure 4 illustrates a schematic diagram of the slot format for SFI indication provided in 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, that is, a slot includes 4 downlink symbols, 7 flexible symbols, and 3 uplink symbols, and is configured with μ SFI =0, meaning the corresponding subcarrier spacing is 15kHz. This SFI is used to indicate the slot format of a Time Division Duplex (TDD) cell, and the corresponding subcarrier spacing μ=1, meaning the corresponding subcarrier spacing is 30kHz. Then the slot format indicated by this SFI is applicable to two consecutive slots, and one downlink symbol indicated by the SFI corresponds to two consecutive downlink symbols in the time slot of this cell, one flexible symbol indicated by the SFI corresponds to two consecutive flexible symbols in the time slot of this cell, and one uplink symbol indicated by the SFI corresponds to two consecutive uplink symbols in the time slot of this cell.

[0064] 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.

[0065] 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 uplink 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.

[0066] 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, similar 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 aforementioned downlink symbols and flexible symbols configured with uplink subbands can be referred to as SBFD symbols.

[0067] Furthermore, UEs that support receiving the aforementioned uplink subband configuration can be referred to as SBFD-aware UEs, while legacy UEs cannot understand the uplink subband configuration and can be referred to as SBFD-no-aware UEs. Taking symbol 2 as an example, from the perspective of an SBFD-aware UE, it understands that symbol 2 has 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 an SBFD-no-aware UE 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.

[0068] 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.

[0069] However, the design of the aforementioned SBFD technology has limitations. First, the definition of SBFD symbol is proposed within the framework of downlink symbols, uplink symbols, and flexible symbols, defining some symbols from downlink and flexible symbols as SBFD symbols. Furthermore, SBFD symbols and flexible symbols have functional overlap, both being used to balance the resource allocation for uplink and downlink services. Second, the configuration of SBFD symbols must be based on semi-static configuration, resulting in poor flexibility and difficulty in adapting to dynamically changing network loads.

[0070] To this end, this application proposes a resource indication method that helps to dynamically indicate time-frequency resources, thereby flexibly meeting uplink and downlink transmission requirements and dynamically balancing network load.

[0071] Figure 6 illustrates a flowchart of a resource indication 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:

[0072] Step 620: The network device sends a first signaling message, which indicates at least one first time unit. The frequency domain resources corresponding to the first time unit include uplink resources and downlink resources.

[0073] In the embodiments of this application, at least one means one or more, and at least one first time unit means one or more first time units.

[0074] In this embodiment of the application, 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 unit is a first symbol, or a first symbol group, or a first time slot, or a first sub-time slot, or a first subframe, or a first frame.

[0075] The frequency domain resources corresponding to the first time unit include uplink and downlink resources. This can be understood as the frequency domain resources corresponding to the first time unit being used for both uplink and downlink transmission. Therefore, network devices can simultaneously receive uplink resources and transmit downlink resources corresponding to the first time unit. The first time unit can also be called an SBFD time unit, indicating a time unit using SBFD technology. For example, the first time unit may be referred to as an SBFD symbol, SBFD symbol group, SBFD time slot, SBFD subframe, SBFD sub-time slot, or SBFD frame.

[0076] In this embodiment of the application, the network device can be implemented as the network device 110 shown in FIG1.

[0077] In summary, the method provided in this application supports network devices sending first signaling to indicate one or more first time units, whereby the first time unit simultaneously supports uplink and downlink transmission. When there is a high volume of uplink traffic, the first signaling can flexibly indicate more uplink resources; conversely, when there is a high volume of downlink traffic, the first signaling can flexibly indicate more downlink resources. This helps to dynamically adjust uplink and downlink resources within the system, achieving dynamic balance of network load and reducing resource conflicts and congestion.

[0078] Figure 7 illustrates a flowchart of a resource indication 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:

[0079] Step 720: The UE receives a first signaling instruction, which indicates at least one first time unit. The frequency domain resources corresponding to the first time unit include uplink resources and downlink resources.

[0080] In the embodiments of this application, at least one means one or more, and at least one first time unit means one or more first time units.

[0081] In this embodiment of the application, 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 unit is a first symbol, or a first symbol group, or a first time slot, or a first sub-time slot, or a first subframe, or a first frame.

[0082] The frequency domain resources corresponding to the first time unit include uplink resources and downlink resources. The first time unit can also be called the SBFD time unit, which indicates the time unit using SBFD technology. For example, the first time unit may be called an SBFD symbol, SBFD symbol group, SBFD time slot, SBFD subframe, SBFD sub-time slot, or SBFD frame.

[0083] In this embodiment, the UE is an SBFD-aware UE, meaning the UE understands that the frequency domain resources corresponding to the first time unit include both uplink and downlink resources; that is, the UE understands the instruction of the first signaling. However, this application does not exclude the possibility of SBFD-no-aware UEs existing in the system. SBFD-no-aware UEs cannot understand the instruction of the first signaling; that is, for SBFD-no-aware UEs, the frequency domain resources corresponding to the first time unit only include downlink resources or only uplink resources. Furthermore, whether it is an SBFD-aware UE or an SBFD-no-aware UE, it can only perform uplink transmission or only downlink reception in the first time unit. In other words, regardless of whether the UE understands the instruction of the first signaling, the UE can only perform half-duplex communication in the first time unit.

[0084] In this embodiment of the application, the UE can be implemented as the terminal device 120 shown in FIG1.

[0085] In summary, the method provided in this application supports a UE receiving a first signaling instruction indicating one or more first time units, where the frequency domain resources corresponding to the first time unit include both uplink and downlink resources. When there is a high volume of uplink traffic, the first signaling instruction can flexibly indicate more uplink resources; conversely, when there is a high volume of downlink traffic, the first signaling instruction can flexibly indicate more downlink resources. This helps to dynamically adjust uplink and downlink resources within the system, achieving dynamic balance of network load and reducing resource conflicts and congestion.

[0086] Furthermore, based on the embodiments shown in Figures 6 and 7, this application also provides a specific design for the instruction of the first signaling, as shown in the embodiments in Figures 8 and 9.

[0087] Figure 8 shows a flowchart of a resource indication 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:

[0088] Step 820: The network device sends a first signaling message, which indicates at least one first time unit. The frequency domain resources corresponding to the first time unit include uplink resources and downlink resources.

[0089] In some embodiments, the first signaling includes at least one of the following: RRC signaling, Media Access Control (MAC) control element (CE), Downlink Control Information (DCI), and System Information.

[0090] In some embodiments, the first signaling indicates one or more of the following: the quantity information of uplink resources, the frequency domain location information of uplink resources, the quantity information of downlink resources, the frequency domain location information of downlink resources, the quantity information of guard bands, and the frequency domain location information of guard bands. Guard bands, also known as guard resources or spaced resources, are located between uplink and downlink resources and help avoid mutual interference between them. Wherein:

[0091] The frequency domain location information of uplink resources 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, and the frequency domain spacing between the uplink and downlink resources. The frequency domain location information of downlink resources includes one or more of the following: the frequency domain start position of the downlink resource, the frequency domain end position of the downlink resource, and the frequency domain spacing between the downlink and uplink resources. The frequency domain location information of the guard band includes one or more of the following: the frequency domain start position of the guard band and the frequency domain end position of the guard band.

[0092] The quantity information of uplink resources includes one or more of the following: the number of frequency domain units included in the uplink resources, the change in the number of frequency domain units included in the uplink resources, and the ratio of the number of frequency domain units in the uplink resources to the number of frequency domain units in the downlink resources. The quantity information of downlink resources includes one or more of the following: the number of frequency domain units included in the downlink resources, the change in the number of frequency domain units included in the downlink resources, and the ratio of the number of frequency domain units in the downlink resources to the number of uplink resources. The quantity information of guard bands includes one or more of the following: the number of frequency domain units included in the guard band, and the change in the number of frequency domain units included in the guard band.

[0093] In this embodiment, the frequency domain unit includes one or more of the following: Physical Resource Block (PRB), Sub-band, Carrier, Bandwidth Part (BWP), Subcarrier, and Resource Element (RE). Taking PRB as an example, the number of frequency domain units mentioned above represents the number of PRBs, the change in frequency domain units represents the change in PRBs, and the proportion of frequency domain units represents the proportion of PRBs. The same applies to other types of frequency domain units, and will not be described in detail here.

[0094] In some embodiments, the frequency domain resources corresponding to the first time unit include flexible resources, which are used for uplink or downlink transmission. Further, the first signaling indicates one or more of the following: the transmission direction of the flexible resources, the frequency domain location information of the flexible resources, the quantity information of the flexible resources, and the quantity information of the guard bands. Wherein:

[0095] • Flexible resources can be transmitted in either downlink or uplink.

[0096] • The frequency domain location information of the flexible resource includes one or more of the following: the frequency domain start position of the flexible resource, the frequency domain end position of the flexible resource, the frequency domain interval between the flexible resource and the uplink resource, and the frequency domain interval between the flexible resource and the downlink resource.

[0097] • The quantity information of flexible resources includes one or more of the following: the number of frequency domain units included in the flexible resources, the change in the number of frequency domain units included in the flexible resources, the ratio of the number of frequency domain units of flexible resources to downlink resources, and the ratio of the number of frequency domain units of flexible resources to uplink resources.

[0098] • The quantity information of the guard band includes one or more of the following: the number of frequency domain units included in the guard band, and the amount of change in the frequency domain units included in the guard band.

[0099] Taking a frequency domain unit including PRBs as an example, the quantity information of flexible resources includes one or more of the following: the number of PRBs included in the flexible resource, the change in the number of PRBs included in the flexible resource, the ratio of the number of PRBs in the flexible resource to the number of PRBs in the downlink resource, and the ratio of the number of PRBs in the flexible resource to the number of PRBs in the uplink resource. The quantity information of guard bands includes one or more of the following: the number of PRBs included in the guard band, and the change in the number of PRBs included in the guard band. The situation is similar for other types of frequency domain units, and will not be elaborated further.

[0100] In some embodiments, the flexible resource is located in the middle portion of the frequency domain resource corresponding to the first time unit, or the flexible resource is located in the edge portion of the frequency domain resource corresponding to the first time unit.

[0101] In some embodiments, the flexible resource is used for downlink transmission, and the guard band between the flexible resource and the downlink resource is also used for downlink transmission. That is, when the frequency domain resources corresponding to the first time unit include at least the flexible resource and the downlink resource, and the transmission direction of the flexible resource is also downlink, and only a guard band exists between the flexible resource and the downlink resource, the guard band between the flexible resource and the downlink resource is also used for downlink transmission. In this case, the flexible resource, the guard band, and the downlink resource can be considered to form a continuous downlink sub-band.

[0102] In some embodiments, the flexible resource is used for uplink transmission, and the guard band between the flexible resource and the uplink resource is also used for uplink transmission. That is, when the frequency domain resources corresponding to the first time unit include at least the flexible resource and the uplink resource, the transmission direction of the flexible resource is also uplink, and only a guard band exists between the flexible resource and the uplink resource, the guard band between the flexible resource and the uplink resource is also used for uplink transmission. In this case, the flexible resource, the guard band, and the uplink resource can be considered to form a continuous uplink sub-band.

[0103] In some embodiments, uplink resources may also be referred to as uplink sub-band (UL Sub-band), downlink resources may also be referred to as downlink sub-band (DL Sub-band), and flexible resources may also be referred to as flexible sub-band (Flexible Sub-band).

[0104] In some embodiments, the first signaling indicates a period corresponding to at least one first time unit. The at least one first time unit repeats this period in the time domain.

[0105] In some embodiments, at least one first time unit is located within a first time-frequency resource, and a first signaling indicates the period of the first time-frequency resource. The first time-frequency resource repeats in the time domain using this period.

[0106] Furthermore, the at least one first time unit indicated by the first signaling is all the time units in the first time-frequency resource, that is, all one or more time units included in the first time-frequency resource are first time units. Alternatively, at least one first time unit is a partial time unit in the first time-frequency resource, that is, the first time-frequency resource includes at least one first time unit and at least one second time unit, and the frequency domain resource corresponding to the second time unit includes only downlink resources or only uplink resources, that is, the second time unit is used only for downlink transmission or only for uplink transmission.

[0107] For example, the first time unit is an SBFD symbol, and the first time-frequency resource includes one or more symbols that are all SBFD symbols; or, at least one SBFD symbol is a part of the symbols in the first time-frequency resource, and the first time-frequency resource also includes uplink symbols (that is, the corresponding frequency domain resource only includes uplink symbols) and / or downlink symbols (that is, the corresponding frequency domain resource only includes downlink symbols).

[0108] For example, the first time unit is an SBFD time slot, and the first time-frequency resource includes one or more time slots that are all SBFD time slots; or, at least one SBFD time slot is a portion of the first time-frequency resource, and the first time-frequency resource also includes uplink time slots (i.e., the corresponding frequency domain resource only includes uplink time slots) and / or downlink time slots (i.e., the corresponding frequency domain resource only includes downlink time slots). The cases where the time unit is of other types are similar and will not be elaborated further.

[0109] In some embodiments, the first signaling further indicates time-domain location information of at least one first time unit, including one or more of the following: time-domain start position of at least one first time unit in the first time-frequency resource, time-domain end position of at least one first time unit in the first time-frequency resource, and index or number of at least one first time unit in the first time-frequency resource.

[0110] Alternatively, if at least one first time unit is a subset of time units in the first time-frequency resource, the first signaling may further indicate the time-domain location information of at least one first time unit, including one or more of the following: the time-domain start position of at least one first time unit in the first time-frequency resource, the time-domain end position of at least one first time unit in the first time-frequency resource, and the index or number of at least one first time unit in the first time-frequency resource. If the at least one first time unit indicated by the first signaling is all time units in the first time-frequency resource, it is not necessary to indicate the time-domain location information of at least one first time unit, thus saving indication overhead.

[0111] In some embodiments, the first signaling indicates an identifier corresponding to at least one first time unit, with different identifiers corresponding to different time-frequency resource patterns. Therefore, the identifier indicated by the first signaling can be used to determine the pattern of at least one first time unit.

[0112] In some embodiments, at least one first time unit is located within a first time-frequency resource, and a first signaling indicates an identifier corresponding to the first time-frequency resource; different identifiers correspond to different time-frequency resource patterns. Therefore, the identifier indicated by the first signaling can be used to determine the pattern of the first time-frequency resource.

[0113] In some embodiments, before the network device sends the first signaling, a second time-frequency resource exists in the system, which is different from the first time-frequency resource. That is, before sending the first signaling, the network device receives and / or sends based on the second time-frequency resource.

[0114] Furthermore, the second time-frequency resource satisfies one or more of the following: the period of the second time-frequency resource is different from the period of the first time-frequency resource; the number of uplink resources in the second time-frequency resource is different from the number of uplink resources in the first time-frequency resource; the frequency domain position of the uplink resources in the second time-frequency resource is different from the frequency domain position of the uplink resources in the first time-frequency resource; the number of downlink resources in the second time-frequency resource is different from the number of downlink resources in the first time-frequency resource; the frequency domain position of the downlink resources in the second time-frequency resource is different from the frequency domain position of the downlink resources in the first time-frequency resource; the number of guard bands in the second time-frequency resource is different from the number of guard bands in the first time-frequency resource; the frequency domain position of the guard bands in the second time-frequency resource is different from the frequency domain position of the guard bands in the first time-frequency resource; the number of first time units in the second time-frequency resource is different from the number of first time units in the first time-frequency resource; the time domain position of the first time unit in the second time-frequency resource is different from the time domain position of the first time unit in the first time-frequency resource; and the pattern of the second time-frequency resource is different from the pattern of the first time-frequency resource.

[0115] In some embodiments, the second time-frequency resource is agreed upon by the communication protocol, or the second time-frequency resource is predefined (e.g., corresponding codes, tables, or other information that can be used to indicate relevant information are pre-stored in the UE and network device), or the second time-frequency resource is semi-statically configured by the network device, or the second time-frequency resource is indicated by a second signaling. The second signaling includes at least one of the following: RRC signaling, MAC CE, DCI, and system information.

[0116] In some embodiments, the total bandwidth of the first time-frequency resource includes the bandwidth of k carriers, where k ≥ 1. For example, if the cell where the network device is located is associated with k carriers, the total bandwidth of the first time-frequency resource is the cell bandwidth of the network device. For example, if the cell where the network device is located is associated with Z carriers, where 1 ≤ k ≤ Z, the total bandwidth of the first time-frequency resource is a portion of the cell bandwidth of the network device.

[0117] In some embodiments, the total bandwidth of the first time-frequency resource includes the bandwidth of k BWPs, where k ≥ 1. For example, the cell bandwidth of the network device includes p BWPs. If 1 ≤ k < p, then the total bandwidth of the first time-frequency resource is the bandwidth of some BWPs in the cell where the network device is located. If k = p, then the total bandwidth of the first time-frequency resource is the cell bandwidth of the network device.

[0118] The total bandwidth of the first time-frequency resource, that is, the total bandwidth of the frequency domain resource corresponding to the first time unit, includes all frequency domain units corresponding to the first time unit.

[0119] Step 840: The network device receives an uplink signal on the uplink resource corresponding to at least one first time unit, and sends a downlink signal on the downlink resource corresponding to at least one first time unit.

[0120] The network device can perform full-duplex communication in at least one first time unit, achieving simultaneous transmission and reception within that first time unit. Uplink signals may include uplink data, and downlink signals may include downlink data. Step 840 is an optional step.

[0121] Other related content can be found in step 620, and will not be repeated here.

[0122] In summary, the method provided in this application supports network devices sending first signaling to indicate one or more first time units, whereby the first time units simultaneously support uplink and downlink transmission. The indication of the first signaling helps to dynamically adjust uplink and downlink resources within the system, achieving dynamic balancing of network load and reducing resource conflicts and congestion. Furthermore, it provides a specific and feasible indication scheme for the first signaling, facilitating flexible indication of transmission resources.

[0123] Figure 9 illustrates a flowchart of a resource indication 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:

[0124] Step 920: The UE receives a first signaling instruction, which indicates at least one first time unit. The frequency domain resources corresponding to the first time unit include uplink resources and downlink resources.

[0125] In some embodiments, the first signaling includes at least one of the following: RRC signaling, MAC CE, DCI, and system information.

[0126] In some embodiments, the first signaling indicates one or more of the following: uplink resource quantity information, uplink resource frequency domain location information, downlink resource quantity information, downlink resource frequency domain location information, guard band quantity information, and guard band frequency domain location information. The guard band, also referred to as guard resource or interval resource, is located between uplink and downlink resources and helps to avoid mutual interference between them. Wherein:

[0127] The frequency domain location information of uplink resources 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, and the frequency domain spacing between the uplink and downlink resources. The frequency domain location information of downlink resources includes one or more of the following: the frequency domain start position of the downlink resource, the frequency domain end position of the downlink resource, and the frequency domain spacing between the downlink and uplink resources. The frequency domain location information of the guard band includes one or more of the following: the frequency domain start position of the guard band and the frequency domain end position of the guard band.

[0128] The quantity information of uplink resources includes one or more of the following: the number of frequency domain units included in the uplink resources, the change in the number of frequency domain units included in the uplink resources, and the ratio of the number of frequency domain units in the uplink resources to the number of frequency domain units in the downlink resources. The quantity information of downlink resources includes one or more of the following: the number of frequency domain units included in the downlink resources, the change in the number of frequency domain units included in the downlink resources, and the ratio of the number of frequency domain units in the downlink resources to the number of uplink resources. The quantity information of guard bands includes one or more of the following: the number of frequency domain units included in the guard band, and the change in the number of frequency domain units included in the guard band.

[0129] In this embodiment, the frequency domain unit includes one or more of the following: PRB, subband, carrier, BWP, subcarrier, RE. Taking PRB as an example, the number of frequency domain units is the number of PRBs, the change in frequency domain units is the change in PRBs, and the ratio of the number of frequency domain units is the ratio of the number of PRBs. The same applies to other types of frequency domain units, and will not be described in detail here.

[0130] In some embodiments, the frequency domain resources corresponding to the first time unit include flexible resources, which are used for uplink or downlink transmission. Further, the first signaling indicates one or more of the following: the transmission direction of the flexible resources, the frequency domain location information of the flexible resources, the quantity information of the flexible resources, and the quantity information of the guard bands. Wherein:

[0131] • Flexible resources can be transmitted in either downlink or uplink.

[0132] • The frequency domain location information of the flexible resource includes one or more of the following: the frequency domain start position of the flexible resource, the frequency domain end position of the flexible resource, the frequency domain interval between the flexible resource and the uplink resource, and the frequency domain interval between the flexible resource and the downlink resource.

[0133] • The quantity information of flexible resources includes one or more of the following: the number of frequency domain units included in the flexible resources, the change in the number of frequency domain units included in the flexible resources, the ratio of the number of frequency domain units of flexible resources to downlink resources, and the ratio of the number of frequency domain units of flexible resources to uplink resources.

[0134] • The quantity information of the guard band includes one or more of the following: the number of frequency domain units included in the guard band, and the amount of change in the frequency domain units included in the guard band.

[0135] Taking a frequency domain unit including PRBs as an example, the quantity information of flexible resources includes one or more of the following: the number of PRBs included in the flexible resource, the change in the number of PRBs included in the flexible resource, the ratio of the number of PRBs in the flexible resource to the number of PRBs in the downlink resource, and the ratio of the number of PRBs in the flexible resource to the number of PRBs in the uplink resource. The quantity information of guard bands includes one or more of the following: the number of PRBs included in the guard band, and the change in the number of PRBs included in the guard band. The situation is similar for other types of frequency domain units, and will not be elaborated further.

[0136] In some embodiments, the flexible resource is located in the middle portion of the frequency domain resource corresponding to the first time unit, or the flexible resource is located in the edge portion of the frequency domain resource corresponding to the first time unit.

[0137] In some embodiments, flexible resources are used for downlink transmission, and the guard band between the flexible resources and the downlink resources is also used for downlink transmission. That is, when the frequency domain resources corresponding to the first time unit include at least flexible resources and downlink resources, the transmission direction of the flexible resources is also downlink, and only a guard band exists between the flexible resources and the downlink resources, the guard band between the flexible resources and the downlink resources is also used for downlink transmission. In this case, the flexible resources, guard band, and downlink resources can be considered to form a continuous downlink sub-band. Furthermore, the UE can receive downlink signals in the continuous downlink sub-band formed by the flexible resources, guard band, and downlink resources, or transmit uplink signals using uplink resources.

[0138] In some embodiments, the flexible resource is used for uplink transmission, and the guard band between the flexible resource and the uplink resource is also used for uplink transmission. That is, when the frequency domain resources corresponding to the first time unit include at least the flexible resource and the uplink resource, and the transmission direction of the flexible resource is also uplink, and only a guard band exists between the flexible resource and the uplink resource, the guard band between the flexible resource and the uplink resource is also used for uplink transmission. In this case, the flexible resource, the guard band, and the uplink resource can be considered to form a continuous uplink sub-band. Furthermore, the UE can transmit uplink signals in the continuous uplink sub-band formed by the flexible resource, the guard band, and the uplink resource, or receive downlink signals in the downlink resources.

[0139] In some embodiments, uplink resources may also be referred to as uplink sub-band (UL Sub-band), downlink resources may also be referred to as downlink sub-band (DL Sub-band), and flexible resources may also be referred to as flexible sub-band (Flexible Sub-band).

[0140] In some embodiments, the first signaling indicates a period corresponding to at least one first time unit. The at least one first time unit repeats this period in the time domain.

[0141] In some embodiments, at least one first time unit is located within a first time-frequency resource, and a first signaling indicates the period of the first time-frequency resource. The first time-frequency resource repeats in the time domain using this period.

[0142] Furthermore, the at least one first time unit indicated by the first signaling is all the time units in the first time-frequency resource, that is, all one or more time units included in the first time-frequency resource are first time units. Alternatively, at least one first time unit is a partial time unit in the first time-frequency resource, that is, the first time-frequency resource includes at least one first time unit and at least one second time unit, and the frequency domain resource corresponding to the second time unit includes only downlink resources or only uplink resources, that is, the second time unit is used only for downlink transmission or only for uplink transmission.

[0143] For example, the first time unit is an SBFD symbol, and the first time-frequency resource includes one or more symbols that are all SBFD symbols; or, at least one SBFD symbol is a part of the symbols in the first time-frequency resource, and the first time-frequency resource also includes uplink symbols (that is, the corresponding frequency domain resource only includes uplink symbols) and / or downlink symbols (that is, the corresponding frequency domain resource only includes downlink symbols).

[0144] For example, the first time unit is an SBFD time slot, and the first time-frequency resource includes one or more time slots that are all SBFD time slots; or, at least one SBFD time slot is a portion of the first time-frequency resource, and the first time-frequency resource also includes uplink time slots (i.e., the corresponding frequency domain resource only includes uplink time slots) and / or downlink time slots (i.e., the corresponding frequency domain resource only includes downlink time slots). The cases where the time unit is of other types are similar and will not be elaborated further.

[0145] In some embodiments, the first signaling further indicates time-domain location information of at least one first time unit, including one or more of the following: time-domain start position of at least one first time unit in the first time-frequency resource, time-domain end position of at least one first time unit in the first time-frequency resource, and index or number of at least one first time unit in the first time-frequency resource.

[0146] Alternatively, if at least one first time unit is a subset of time units in the first time-frequency resource, the first signaling may further indicate the time-domain location information of at least one first time unit, including one or more of the following: the time-domain start position of at least one first time unit in the first time-frequency resource, the time-domain end position of at least one first time unit in the first time-frequency resource, and the index or number of at least one first time unit in the first time-frequency resource. If the at least one first time unit indicated by the first signaling is all time units in the first time-frequency resource, it is not necessary to indicate the time-domain location information of at least one first time unit, thus saving indication overhead.

[0147] In some embodiments, the first signaling indicates an identifier corresponding to at least one first time unit, with different identifiers corresponding to different time-frequency resource patterns. Therefore, the identifier indicated by the first signaling can be used to determine the pattern of at least one first time unit.

[0148] In some embodiments, at least one first time unit is located within a first time-frequency resource, and a first signaling indicates an identifier corresponding to the first time-frequency resource; different identifiers correspond to different time-frequency resource patterns. Therefore, the identifier indicated by the first signaling can be used to determine the pattern of the first time-frequency resource.

[0149] In some embodiments, the UE determines at least one first time unit and its corresponding frequency domain resources based on the received first signaling. For example, it determines the time domain location, number of time units, frequency domain location, and number of frequency domain units of the at least one first time unit. Alternatively, the UE determines the pattern corresponding to the at least one first time unit based on the received first signaling.

[0150] In some embodiments, the UE determines a first time-frequency resource based on the received first signaling, such as determining the time-domain location, number of time units, frequency-domain location, and number of frequency-domain units of the first time-frequency resource. Alternatively, the UE can be understood as determining the pattern of the first time-frequency resource based on the received first signaling.

[0151] In some embodiments, before the UE receives the first signaling, a second time-frequency resource exists in the system, and the second time-frequency resource is different from the first time-frequency resource. That is, before receiving the first signaling, the UE transmits and / or receives based on the second time-frequency resource.

[0152] Furthermore, the second time-frequency resource satisfies one or more of the following: the period of the second time-frequency resource is different from the period of the first time-frequency resource; the number of uplink resources in the second time-frequency resource is different from the number of uplink resources in the first time-frequency resource; the frequency domain position of the uplink resources in the second time-frequency resource is different from the frequency domain position of the uplink resources in the first time-frequency resource; the number of downlink resources in the second time-frequency resource is different from the number of downlink resources in the first time-frequency resource; the frequency domain position of the downlink resources in the second time-frequency resource is different from the frequency domain position of the downlink resources in the first time-frequency resource; the number of guard bands in the second time-frequency resource is different from the number of guard bands in the first time-frequency resource; the frequency domain position of the guard bands in the second time-frequency resource is different from the frequency domain position of the guard bands in the first time-frequency resource; the number of first time units in the second time-frequency resource is different from the number of first time units in the first time-frequency resource; the time domain position of the first time unit in the second time-frequency resource is different from the time domain position of the first time unit in the first time-frequency resource; and the pattern of the second time-frequency resource is different from the pattern of the first time-frequency resource.

[0153] In some embodiments, the second time-frequency resource is agreed upon by the communication protocol, or the second time-frequency resource is predefined (e.g., corresponding codes, tables, or other information that can be used to indicate relevant information are pre-stored in the UE and network device), or the second time-frequency resource is semi-statically configured by the network device, or the second time-frequency resource is indicated by a second signaling. The second signaling includes at least one of the following: RRC signaling, MAC CE, DCI, and system information.

[0154] Step 940a: The UE sends an uplink signal in the uplink resource corresponding to at least one first time unit.

[0155] Step 940b: The UE receives a downlink signal in at least one downlink resource corresponding to a first time unit.

[0156] Steps 940a and 940b are optional, and the UE cannot perform steps 940a and 940b simultaneously. The UE performs half-duplex communication in at least one first time unit. Uplink signals may include uplink data, and downlink signals may include downlink data.

[0157] Other related content can be found in step 720, and will not be repeated here.

[0158] In summary, the method provided in this application involves a UE receiving a first signaling instruction indicating one or more first time units. The frequency domain resources corresponding to the first time units include both uplink and downlink resources. The indication of the first signaling instruction helps to dynamically adjust uplink and downlink resources within the system, achieving dynamic balancing of network load and reducing resource conflicts and congestion. Furthermore, it provides a specific and feasible indication scheme for the first signaling instruction, facilitating flexible indication of transmission resources. The UE can adjust the resources it uses in a timely manner based on the dynamic first signaling instruction.

[0159] Figure 10 illustrates a schematic diagram of a first time unit provided in an exemplary embodiment of this application. The frequency domain resources corresponding to the first time unit include uplink resources and downlink resources, and a guard band exists between the uplink resources and the downlink resources. The uplink resources may be located in the middle or edge portion of the frequency domain resources corresponding to the first time unit. The uplink resources may also be referred to as uplink sub-bands, and the downlink resources may also be referred to as downlink sub-bands.

[0160] In Figure 10(a), the uplink resource is located in the middle part of the frequency domain resource corresponding to the first time unit, and the upper and lower edges of the frequency domain resource corresponding to the first time unit are both downlink resources. In Figure 10(b), the uplink resource is located in the upper edge of the frequency domain resource corresponding to the first time unit, and the remaining resources, excluding the uplink resource and the guard band, are downlink resources. In Figure 10(c), the uplink resource is located in the lower edge of the frequency domain resource corresponding to the first time unit, and the remaining resources, excluding the uplink resource and the guard band, are downlink resources.

[0161] The first time unit shown in Figure 10 is applicable to the embodiments shown in Figures 6 to 9. The network device can indicate at least one first time unit via first signaling, and the UE can determine the time domain location, number of time units, frequency domain location, and number of frequency domain units of at least one first time unit via first signaling. Furthermore, the uplink resources, downlink resources, and guard bands corresponding to different first time units may be the same or different; that is, the structures of the multiple first time units indicated by the first signaling may be the same or different. The first time unit is an SBFD symbol, or an SBFD symbol group, or an SBFD time slot, or an SBFD subframe, or an SBFD sub-time slot, or an SBFD frame.

[0162] Taking the first time unit shown in Figure 10 as an example, which is an SBFD symbol, Figure 11 shows a schematic diagram of time-frequency resources including at least one first time unit. It is assumed that all symbols in the first time-frequency resource are SBFD symbols, that is, at least one SBFD symbol indicated by the first signaling is all the symbols in the first time-frequency resource.

[0163] The network device sends a first signaling message, which is used to indicate at least one SBFD symbol. This can also be understood as indicating a first time-frequency resource. The first time-frequency resource is the time-frequency resource included in period 2 of Figure 11; therefore, each symbol included in period 2 is an SBFD symbol.

[0164] In some embodiments, before the network device sends the first signaling, a second time-frequency resource exists in the system, which is different from the first time-frequency resource. The second time-frequency resource is the time-frequency resource included in period 1 of Figure 11. The design of the second time-frequency resource can be referred to the relevant content in steps 820 and 920, which will not be repeated here. Figure 11 takes the example where all symbols in the second time-frequency resource are SBFD symbols. The frequency domain resources corresponding to each SBFD symbol include uplink resources, downlink resources, and guard bands.

[0165] The first signaling instruction indicates one or more of the following: the quantity information of uplink resources corresponding to at least one SBFD symbol, the frequency domain location of uplink resources corresponding to at least one SBFD symbol, the quantity information of guard bands corresponding to at least one SBFD symbol, the frequency domain location of guard bands corresponding to at least one SBFD symbol, the quantity information of downlink resources corresponding to at least one SBFD symbol, and the frequency domain location of downlink resources corresponding to at least one SBFD symbol.

[0166] In some embodiments, the first signaling indicates uplink resource quantity information. Taking a frequency domain unit (PRB) as an example, the uplink resource quantity information includes at least one of the following: the number of PRBs included in the uplink resources, the change in the number of PRBs included in the uplink resources, and the ratio of the number of PRBs in the uplink resources to the number of PRBs in the downlink resources.

[0167] For example, the first signaling indicates that the number of PRBs included in the uplink resources is N (N is an integer greater than or equal to 1). Therefore, the UE can determine from the first signaling that the uplink subband corresponding to each SBFD symbol in period 2 includes N PRBs.

[0168] For example, the first signaling indicates that the PRB change in the uplink resources is X (X is an integer). The number of PRBs in the uplink resources corresponding to a single SBFD symbol in the first time-frequency resource is N, which is determined by the UE based on the number of PRBs N1 in the uplink resources corresponding to a single SBFD symbol in the second time-frequency resource and the PRB change X indicated by the first signaling. Assuming that the uplink subband corresponding to each SBFD symbol in period 1 includes N1 PRBs, then the UE can determine that the uplink subband corresponding to each SBFD symbol in period 2 includes N = (N1 + X) PRBs based on the first signaling. The PRB change X indicated by the first signaling can be a positive integer, indicating that the bandwidth of the uplink resources corresponding to a single SBFD symbol in the first time-frequency resource is greater than the bandwidth of the uplink resources corresponding to a single SBFD symbol in the second time-frequency resource. The PRB change X indicated by the first signaling can be 0, indicating that the bandwidth of the uplink resources corresponding to a single SBFD symbol in the first time-frequency resource is equal to the bandwidth of the uplink resources corresponding to a single SBFD symbol in the second time-frequency resource. The PRB change X indicated by the first signaling can be a negative integer, which means that the bandwidth of the uplink resource corresponding to a single SBFD symbol in the first time-frequency resource is less than the bandwidth of the uplink resource corresponding to a single SBFD symbol in the second time-frequency resource.

[0169] For example, the first signaling indicates the ratio of the number of PRBs in the uplink resources to the number of PRBs in the downlink resources. Since the total number of PRBs included in a carrier or BWP is fixed, based on the number of PRBs included in the guard band and the ratio of the number of PRBs in the uplink resources to the number of PRBs in the downlink resources, the UE can determine the number of PRBs included in the uplink subband and downlink subband corresponding to each SBFD symbol in period 2. The number of PRBs included in the guard band can be default, or agreed upon by the communication protocol, or indicated by the network device (also indicated by the first signaling, or indicated separately), or determined by the UE (e.g., determined according to predefined rules).

[0170] For example, the bandwidth of the first time-frequency resource is A PRBs, meaning the total number of PRBs corresponding to a single SBFD symbol is A, and the communication protocol stipulates that the number of PRBs in the guard band is B. If the first signaling indicates that the ratio of uplink resources to downlink resources is 1:1, then the number of PRBs for both uplink and downlink resources is (AB) / 2. If the first signaling indicates that the ratio of uplink resources to downlink resources is 1:2, then the number of PRBs for uplink resources is (AB) / 3, and the number of PRBs for downlink resources is (AB)*2 / 3.

[0171] Therefore, based on the uplink resource quantity information indicated by the first signaling, the UE can determine the number of PRBs in the uplink subband corresponding to each SBFD symbol in period 2, that is, it can clearly determine the bandwidth of the uplink resources included in the frequency domain resources corresponding to each first time unit within the first time-frequency resource.

[0172] Furthermore, when the first signaling indicates the quantity information of uplink resources, the UE can determine the time-frequency resource pattern of period 2, that is, determine the pattern of the first time-frequency resource, based on the frequency domain location of the uplink resources indicated by the first signaling and the quantity information of the guard band (including the total number of PRBs of the guard band and / or the number of PRBs distributed on the side of the uplink resources of the guard band).

[0173] In some embodiments, the frequency domain position of the uplink resource is default (for example, the default frequency domain center position of the uplink resource in the first time-frequency resource is the same as the frequency domain center position of the uplink resource in the second time-frequency resource, and / or, the default frequency domain start position of the uplink resource in the first time-frequency resource is the same as the frequency domain start position of the uplink resource in the second time-frequency resource, and / or, the default frequency domain end position of the uplink resource in the first time-frequency resource is the same as the frequency domain end position of the uplink resource in the second time-frequency resource, and / or, the default frequency domain center position of the uplink resource in the first time-frequency resource is the frequency domain center position of the carrier, and / or, the default frequency domain center position of the uplink resource in the first time-frequency resource is the frequency domain center position of the BWP ... The frequency domain start position of the resource is the frequency domain start position of the carrier, and / or, by default, the frequency domain start position of the uplink resource in the first time-frequency resource is the frequency domain start position of the BWP, and / or, by default, the frequency domain end position of the uplink resource in the first time-frequency resource is the frequency domain end position of the carrier, and / or, by default, the frequency domain end position of the uplink resource in the first time-frequency resource is the frequency domain end position of the BWP; or, the frequency domain position of the uplink resource is agreed upon by the communication protocol; or, the frequency domain position of the uplink resource is indicated by the network device (also indicated by the first signaling, or indicated separately); or, it is determined by the UE (e.g., determined according to predefined rules); or, the frequency domain position of the uplink resource in the first time-frequency resource is associated with the frequency domain position of the uplink resource in the second time-frequency resource.

[0174] In some embodiments, the number of PRBs included in the guard band is default (e.g., the number of PRBs included in the guard band in the first time-frequency resource is the same as the number of PRBs included in the guard band in the second time-frequency resource by default), or is agreed upon by the communication protocol, or is indicated by the network device (also indicated by the first signaling, or separately), or is determined by the UE (e.g., determined according to predefined rules), or the number of PRBs included in the guard band in the first time-frequency resource is associated with the number of PRBs included in the guard band in the second time-frequency resource.

[0175] In some embodiments, the distribution of the guard band on the uplink resource side is default (e.g., the default distribution of the guard band on the uplink resource side in the first time-frequency resource is the same as the distribution of the guard band on the uplink resource side in the second time-frequency resource), or it is agreed upon by the communication protocol, or it is indicated by the network device (also indicated by the first signaling, or indicated separately), or it is determined by the UE (e.g., determined according to predefined rules), or the distribution of the guard band on the uplink resource side in the first time-frequency resource is associated with the distribution of the guard band on the uplink resource side in the second time-frequency resource.

[0176] For example, the first signaling indicates that the number of PRBs in the uplink subband is N. Assume that the number of PRBs included in the uplink subband in period 1 is N1, and N > N1. Assume that the number of PRBs included in the guard band in period 2 is the same as the number of PRBs included in the guard band in period 1, and the distribution of the guard band on both sides of the uplink subband in period 2 is consistent with the distribution of the guard band on both sides of the uplink subband in period 1. For example, the guard band includes b PRBs below the frequency domain start position of the uplink subband and / or a PRBs above the frequency domain end position of the uplink subband, where a and b may have the same or different values, a is an integer greater than or equal to 1, and b is an integer greater than or equal to 1.

[0177] If the frequency domain center position of the uplink sub-band in period 2 is the same as that of the uplink sub-band in period 1, the UE determines the time-frequency resource pattern of period 2 according to the instruction of the first signaling, the frequency domain position of the uplink resources, and the number of guard bands, as shown in Figure 11(a).

[0178] If the frequency domain starting position of the uplink subband in period 2 is the same as the frequency domain starting position of the uplink subband in period 1, the UE determines the time-frequency resource pattern of period 2 according to the instruction of the first signaling, the frequency domain position of the uplink resources, and the number of guard bands, as shown in Figure 11(b).

[0179] If the frequency domain end position of the uplink subband in period 2 is the same as the frequency domain end position of the uplink subband in period 1, the UE determines the time-frequency resource pattern of period 2 according to the instruction of the first signaling, the frequency domain position of the uplink resources, and the number of guard bands, as shown in Figure 11(c).

[0180] Therefore, when the first signaling indicates the quantity of uplink resources, since the frequency domain location, number, and distribution of guard bands of the uplink resources are known (predefined, configured by network devices, or associated in periods 1 and 2), the UE can determine the first time-frequency resource in period 2 according to the indication of the first signaling. It can be understood that after the number and frequency domain location of PRBs in the uplink sub-band and guard band are determined, the remaining PRBs corresponding to the SBFD symbols belong to the downlink sub-band. In other words, the number and frequency domain location of PRBs in the downlink sub-band can be determined after determining the number and frequency domain location of PRBs in the uplink sub-band and guard band. For example, if the bandwidth of the first time-frequency resource is the bandwidth of k carriers, the remaining PRBs in the k carriers excluding the uplink sub-band and guard band belong to the downlink sub-band, where k ≥ 1. Or, if the bandwidth of the first time-frequency resource is the bandwidth of a BWP, the remaining PRBs in this BWP excluding the uplink sub-band and guard band belong to the downlink sub-band.

[0181] For example, the first signaling indicates the number of PRBs in the uplink subband and the number of PRBs in the guard band. Assume the first signaling indicates that the number of PRBs in the uplink subband is N, and that the guard band includes b PRBs and / or a PRBs, where a and b may have the same or different values, a is an integer greater than or equal to 1, and b is an integer greater than or equal to 1. This means that the guard band includes b PRBs below the start position of the uplink subband in the frequency domain and / or a PRBs above the end position of the uplink subband in the frequency domain.

[0182] If the frequency domain center position of the uplink subband in period 2 is the same as that of the uplink subband in period 1, the UE determines the time-frequency resource pattern of period 2 according to the instruction of the first signaling and the frequency domain position of the uplink resources, as shown in Figure 11(a).

[0183] If the frequency domain starting position of the uplink subband in period 2 is the same as the frequency domain starting position of the uplink subband in period 1, the UE determines the time-frequency resource pattern of period 2 according to the instruction of the first signaling and the frequency domain position of the uplink resources, as shown in Figure 11(b).

[0184] If the frequency domain end position of the uplink subband in period 2 is the same as the frequency domain end position of the uplink subband in period 1, the UE determines the time-frequency resource pattern of period 2 according to the instruction of the first signaling and the frequency domain position of the uplink resources, as shown in Figure 11(c).

[0185] Therefore, given the information on the number of uplink resources and guard bands indicated by the first signaling, since the frequency domain location of the uplink resources is known (predefined, configured by network devices, or associated in periods 1 and 2), and the guard band is located on either side or one side of the uplink resources' frequency domain, the UE can determine the first time-frequency resource in period 2 according to the indication of the first signaling. It can be understood that after the number and frequency domain location of the PRBs in the uplink sub-band and guard band are determined, the remaining PRBs corresponding to the SBFD symbols belong to the downlink sub-band. In other words, the number and frequency domain location of the PRBs in the downlink sub-band can be determined after determining the number and frequency domain location of the PRBs in the uplink sub-band and guard band. For example, if the bandwidth of the first time-frequency resource is the bandwidth of k carriers, the remaining PRBs in those k carriers, excluding the uplink sub-band and guard band, belong to the downlink sub-band, where k ≥ 1. Or, if the bandwidth of the first time-frequency resource is the bandwidth of a BWP, the remaining PRBs in that BWP, excluding the uplink sub-band and guard band, belong to the downlink sub-band.

[0186] In some embodiments, the first signaling indicates the frequency domain location and the number of frequency domain units of the uplink resource. The frequency domain location of the uplink resource may include, for example, the frequency domain start location, and / or the frequency domain end location, and / or the frequency domain center location of the uplink resource.

[0187] For example, the first signaling indicates the frequency domain start position F_start of the uplink subband and the number of PRBs N. Assume that the number of PRBs in the guard band in period 2 is the same as the number of PRBs in the guard band in period 1, and the distribution of the guard band on both sides of the uplink subband in period 2 is consistent with the distribution of the guard band on both sides of the uplink subband in period 1. For instance, the guard band includes b PRBs below the frequency domain start position of the uplink subband and / or a PRBs above the frequency domain end position of the uplink subband, where a and b may have the same or different values, a is an integer greater than or equal to 1, and b is an integer greater than or equal to 1. Then, the UE can determine the time-frequency resource pattern of period 2 based on the indication of the first signaling, as well as the number and distribution of the guard bands, referring to Figure 12(a).

[0188] For example, the first signaling indicates the frequency domain end position F_end of the uplink subband and the number of PRBs N. Assume that the number of PRBs in the guard band in period 2 is the same as the number of PRBs in the guard band in period 1, and the distribution of the guard band on both sides of the uplink subband in period 2 is consistent with the distribution of the guard band on both sides of the uplink subband in period 1. For instance, the guard band includes b PRBs below the frequency domain start position of the uplink subband and / or a PRBs above the frequency domain end position of the uplink subband, where a and b may have the same or different values, a is an integer greater than or equal to 1, and b is an integer greater than or equal to 1. Then, the UE can determine the time-frequency resource pattern of period 2 based on the indication of the first signaling and the number and distribution of the guard bands, as shown in Figure 12(b).

[0189] For example, the first signaling indicates the frequency domain center position and the number N of PRBs in the uplink sub-band. Assume the number of PRBs in the guard band in period 2 is the same as in period 1, and the distribution of the guard band on both sides of the uplink sub-band in period 2 is consistent with the distribution of the guard band on both sides of the uplink sub-band in period 1. For instance, the guard band includes b PRBs below the frequency domain start position of the uplink sub-band and / or a PRBs above the frequency domain end position of the uplink sub-band, where a and b may have the same or different values, where a is an integer greater than or equal to 1, and b is an integer greater than or equal to 1. Then, the UE can determine the time-frequency resource pattern of period 2 based on the indication of the first signaling and the number and distribution of the guard bands.

[0190] Therefore, when the first signaling indicates the frequency domain location and PRB quantity of the uplink resource, since the guard band quantity information is known (predefined, configured by the network device, or associated in period 1 and period 2), and the guard band is located on both sides or one side of the uplink resource's frequency domain, the UE can determine the first time-frequency resource in period 2 according to the first signaling indication. It can be understood that after the PRB quantity and frequency domain location of the uplink sub-band and guard band are determined, the remaining PRBs corresponding to the SBFD symbol belong to the downlink sub-band. That is, the PRB quantity and frequency domain location of the downlink sub-band can be determined after determining the PRB quantity and frequency domain location of the uplink sub-band and guard band. For example, if the bandwidth of the first time-frequency resource is the bandwidth of k carriers, the remaining PRBs in the k carriers excluding the uplink sub-band and guard band belong to the downlink sub-band, where k ≥ 1. Or, if the bandwidth of the first time-frequency resource is the bandwidth of a BWP, the remaining PRBs in this BWP excluding the uplink sub-band and guard band belong to the downlink sub-band.

[0191] In some embodiments, the first signaling indicates information about the number of guard bands, the frequency domain location of the uplink resource, and the number of frequency domain cells. The number of guard bands includes: the total number of PRBs in the guard band, and / or the number of PRBs distributed along the sides of the uplink resource. The frequency domain location of the uplink resource includes: the frequency domain start position, and / or the frequency domain end position, and / or the frequency domain center position of the uplink resource.

[0192] For example, the first signaling indicates that the guard band includes b PRBs below the frequency domain start position of the uplink subband and / or a PRBs above the frequency domain end position of the uplink subband, and indicates the frequency domain start position F_start of the uplink subband and the number of PRBs N. a and b may have the same or different values, where a is an integer greater than or equal to 1 and b is an integer greater than or equal to 1. Then, the UE can determine the time-frequency resource pattern of period 2 according to the indication of the first signaling, referring to Figure 12(a).

[0193] Therefore, given the information on the number of guard bands, the frequency domain location of uplink resources, and the number of PRBs in the first signaling instruction, the guard band may be located on either side or on one side of the uplink resource's frequency domain. The UE can then determine the first time-frequency resource in period 2 based on the first signaling instruction. It can be understood that after the number and frequency domain location of PRBs in the uplink sub-band and guard band are determined, the remaining PRBs corresponding to the SBFD symbols belong to the downlink sub-band. In other words, the number and frequency domain location of PRBs in the downlink sub-band can be determined after determining the number and frequency domain location of PRBs in the uplink sub-band and guard band. For example, if the bandwidth of the first time-frequency resource is the bandwidth of k carriers, the remaining PRBs in those k carriers, excluding the uplink sub-band and guard band, belong to the downlink sub-band, where k ≥ 1. Or, if the bandwidth of the first time-frequency resource is the bandwidth of a BWP, the remaining PRBs in that BWP, excluding the uplink sub-band and guard band, belong to the downlink sub-band.

[0194] Figure 13 illustrates a schematic diagram of a first time unit provided in an exemplary embodiment of this application. The frequency domain resources corresponding to the first time unit include uplink resources and downlink resources, and a guard band exists between the uplink resources and the downlink resources. The downlink resources may be located in the middle or edge portion of the frequency domain resources corresponding to the first time unit. The uplink resources may also be referred to as uplink sub-bands, and the downlink resources may also be referred to as downlink sub-bands.

[0195] In Figure 13(a), the downlink resources are located in the middle part of the frequency domain resources corresponding to the first time unit, and the upper and lower edges of the frequency domain resources corresponding to the first time unit are both uplink resources. In Figure 13(b), the downlink resources are located in the upper edge of the frequency domain resources corresponding to the first time unit, and the remaining resources, excluding the downlink resources and the guard band, are uplink resources. In Figure 13(c), the downlink resources are located in the lower edge of the frequency domain resources corresponding to the first time unit, and the remaining resources, excluding the downlink resources and the guard band, are uplink resources.

[0196] The first time unit shown in Figure 13 is applicable to the embodiments shown in Figures 6 to 9. The network device can indicate at least one first time unit via first signaling, and the UE can determine the time domain location, number of time units, frequency domain location, and number of frequency domain units of at least one first time unit via first signaling. Furthermore, the uplink resources, downlink resources, and guard bands corresponding to different first time units may be the same or different; that is, the structures of multiple first time units indicated by the first signaling may be the same or different. The first time unit is an SBFD symbol, or an SBFD symbol group, or an SBFD time slot, or an SBFD subframe, or an SBFD sub-time slot, or an SBFD frame.

[0197] Taking the first time unit shown in Figure 13 as an example, it is assumed that all symbols in the first time-frequency resource are SBFD symbols, that is, at least one SBFD symbol indicated by the first signaling is all symbols in the first time-frequency resource.

[0198] The network device sends a first signaling message, which is used to indicate at least one SBFD symbol, or it can be understood as the first signaling message being used to indicate a first time-frequency resource.

[0199] In some embodiments, before the network device sends the first signaling, the system has a second time-frequency resource, which is different from the first time-frequency resource. The design of the second time-frequency resource can be referred to the relevant content in steps 820 and 920, and will not be repeated here.

[0200] The first signaling instruction indicates one or more of the following: the quantity information of uplink resources corresponding to at least one SBFD symbol, the frequency domain location of uplink resources corresponding to at least one SBFD symbol, the quantity information of guard bands corresponding to at least one SBFD symbol, the frequency domain location of guard bands corresponding to at least one SBFD symbol, the quantity information of downlink resources corresponding to at least one SBFD symbol, and the frequency domain location within downlink resources corresponding to at least one SBFD symbol.

[0201] In some embodiments, the first signaling indicates downlink resource quantity information. Taking a frequency domain unit (PRB) as an example, the downlink resource quantity information includes at least one of the following: the number of PRBs included in the downlink resources, the change in the number of PRBs included in the downlink resources, and the ratio of the number of PRBs in the downlink resources to the number of uplink resources.

[0202] For example, the first signaling indicates that the downlink resources include M PRBs (M is an integer greater than or equal to 1). Therefore, the UE can determine from the first signaling that the downlink subband corresponding to each SBFD symbol in period 2 includes M PRBs.

[0203] For example, the first signaling indicates that the change in PRBs included in the downlink resources is Y (Y is an integer). The number of PRBs included in the downlink resources corresponding to a single SBFD symbol in the first time-frequency resource is M, which is determined by the UE based on the number of PRBs M1 included in the downlink resources corresponding to a single SBFD symbol in the second time-frequency resource and the change in PRBs included in the downlink resources indicated by the first signaling Y. Assuming that the downlink subband corresponding to each SBFD symbol in period 1 includes M1 PRBs, then the UE can determine that the downlink subband corresponding to each SBFD symbol in period 2 includes M = (M1 + Y) PRBs based on the first signaling. The change in PRBs Y indicated by the first signaling can be a positive integer, which indicates that the bandwidth of the downlink resources corresponding to a single SBFD symbol in the first time-frequency resource is greater than the bandwidth of the downlink resources corresponding to a single SBFD symbol in the second time-frequency resource. The change in PRBs Y indicated by the first signaling can be 0, which indicates that the bandwidth of the downlink resources corresponding to a single SBFD symbol in the first time-frequency resource is equal to the bandwidth of the downlink resources corresponding to a single SBFD symbol in the second time-frequency resource. If the PRB change Y indicated by the first signaling can be a negative integer, it means that the bandwidth of the downlink resource corresponding to a single SBFD symbol in the first time-frequency resource is less than the bandwidth of the downlink resource corresponding to a single SBFD symbol in the second time-frequency resource.

[0204] For example, the first signaling indicates the ratio of the number of PRBs in downlink resources to the number of PRBs in uplink resources. Since the total number of PRBs included in a carrier or BWP is fixed, based on the number of PRBs included in the guard band and the ratio of the number of PRBs in downlink resources to the number of PRBs in uplink resources, the UE can determine the number of PRBs included in the uplink subband and downlink subband corresponding to each SBFD symbol in period 2. The number of PRBs included in the guard band can be a default value, or it can be agreed upon by the communication protocol, or it can be indicated by the network device (also indicated by the first signaling, or indicated separately), or it can be determined by the UE (e.g., determined according to predefined rules).

[0205] For example, the bandwidth of the first time-frequency resource is A PRBs, meaning the total number of PRBs corresponding to a single SBFD symbol is A, and the communication protocol stipulates that the number of PRBs in the guard band is B. If the first signaling indicates that the ratio of downlink resources to uplink resources is 1:1, then the number of PRBs for both downlink and uplink resources is (AB) / 2. If the first signaling indicates that the ratio of downlink resources to uplink resources is 2:1, then the number of PRBs for downlink resources is (AB)*2 / 3, and the number of PRBs for uplink resources is (AB) / 3.

[0206] Therefore, based on the downlink resource quantity information indicated by the first signaling, the UE can determine the number of PRBs in the downlink subband corresponding to each SBFD symbol in period 2, that is, it can clearly determine the bandwidth of the downlink resources included in the frequency domain resources corresponding to each first time unit within the first time-frequency resource.

[0207] Furthermore, when the first signaling indicates the quantity information of downlink resources, the UE can determine the time-frequency resource pattern of period 2, that is, determine the pattern of the first time-frequency resource, based on the indication of the first signaling, the frequency domain location of the downlink resources, and the quantity information of the guard band (including the total number of PRBs of the guard band and / or the number of PRBs distributed on the side of the downlink resources of the guard band).

[0208] In some embodiments, the frequency domain position of the downlink resource is default (for example, the frequency domain center position of the downlink resource in the first time-frequency resource is the same as the frequency domain center position of the downlink resource in the second time-frequency resource by default, and / or, the frequency domain start position of the downlink resource in the first time-frequency resource is the same as the frequency domain start position of the downlink resource in the second time-frequency resource by default, and / or, the frequency domain end position of the downlink resource in the first time-frequency resource is the same as the frequency domain end position of the downlink resource in the second time-frequency resource by default, and / or, the frequency domain center position of the downlink resource in the first time-frequency resource is the frequency domain center position of the carrier by default, and / or, the frequency domain center position of the downlink resource in the first time-frequency resource is the frequency domain center position of the BWP by default, and / or, the frequency domain center position of the downlink resource in the first time-frequency resource is the frequency domain center position of the BWP by default). The frequency domain start position of the resource is the frequency domain start position of the carrier, and / or, by default, the frequency domain start position of the downlink resource in the first time-frequency resource is the frequency domain start position of the BWP, and / or, by default, the frequency domain end position of the downlink resource in the first time-frequency resource is the frequency domain end position of the carrier, and / or, by default, the frequency domain end position of the downlink resource in the first time-frequency resource is the frequency domain end position of the BWP; or, the frequency domain position of the downlink resource is agreed upon by the communication protocol; or, the frequency domain position of the downlink resource is indicated by the network device (also indicated by the first signaling, or indicated separately); or, it is determined by the UE (e.g., determined according to predefined rules); or, the frequency domain position of the downlink resource in the first time-frequency resource is associated with the frequency domain position of the downlink resource in the second time-frequency resource.

[0209] In some embodiments, the number of PRBs included in the guard band is default (e.g., the number of PRBs included in the guard band in the first time-frequency resource is the same as the number of PRBs included in the guard band in the second time-frequency resource by default), or is agreed upon by the communication protocol, or is indicated by the network device (also indicated by the first signaling, or separately), or is determined by the UE (e.g., determined according to predefined rules), or the number of PRBs included in the guard band in the first time-frequency resource is associated with the number of PRBs included in the guard band in the second time-frequency resource.

[0210] In some embodiments, the distribution of the guard band on both sides of the downlink resource is default (e.g., the default distribution of the guard band on both sides of the downlink resource in the first time-frequency resource is the same as the distribution of the guard band on both sides of the downlink resource in the second time-frequency resource), or it is agreed upon by the communication protocol, or it is indicated by the network device (also indicated by the first signaling, or indicated separately), or it is determined by the UE (e.g., determined according to predefined rules), or the distribution of the guard band on both sides of the downlink resource in the first time-frequency resource is associated with the distribution of the guard band on both sides of the downlink resource in the second time-frequency resource.

[0211] For example, the first signaling indicates that the number of PRBs in the downlink subband is M. Assume that the number of PRBs included in the downlink subband in period 1 is M1, and the number of PRBs included in the guard band in period 2 is the same as the number of PRBs included in the guard band in period 1, and the distribution of the guard band on both sides of the downlink subband in period 2 is consistent with the distribution of the guard band on both sides of the downlink subband in period 1. For example, the guard band includes b PRBs below the frequency domain start position of the downlink subband and / or a PRBs above the frequency domain end position of the downlink subband, where a and b may have the same or different values, a is an integer greater than or equal to 1, and b is an integer greater than or equal to 1.

[0212] Therefore, when the first signaling indicates the quantity of downlink resources, since the frequency domain location, number, and distribution of guard bands of the downlink resources are known (predefined, configured by network devices, or associated in periods 1 and 2), the UE can determine the first time-frequency resource in period 2 according to the indication of the first signaling. It can be understood that after the number and frequency domain location of PRBs in the downlink sub-band and guard band are determined, the remaining PRBs corresponding to the SBFD symbols belong to the uplink sub-band. That is, the number and frequency domain location of PRBs in the uplink sub-band can be determined after determining the number and frequency domain location of PRBs in the downlink sub-band and guard band. For example, if the bandwidth of the first time-frequency resource is the bandwidth of k carriers, the remaining PRBs in the k carriers excluding the downlink sub-band and guard band belong to the uplink sub-band, where k ≥ 1. Or, if the bandwidth of the first time-frequency resource is the bandwidth of a BWP, the remaining PRBs in this BWP excluding the downlink sub-band and guard band belong to the uplink sub-band.

[0213] For example, the first signaling indicates the number of PRBs in the downlink subband and the number of PRBs in the guard band. Assume the first signaling indicates that the number of PRBs in the downlink subband is M, and that the guard band includes b PRBs and / or a PRBs, where a and b may have the same or different values, a is an integer greater than or equal to 1, and b is an integer greater than or equal to 1. This means that the guard band includes b PRBs below the frequency domain start position of the downlink subband and / or a PRBs above the frequency domain end position of the downlink subband.

[0214] Therefore, when the first signaling indicates the quantity information of downlink resources and guard bands, since the frequency domain location of the downlink resources is known (predefined, configured by network devices, or associated in period 1 and period 2), and the guard band is located on both sides or one side of the downlink resources' frequency domain, the UE can determine the first time-frequency resource in period 2 according to the indication of the first signaling. It can be understood that after the quantity and frequency domain location of the PRBs in the downlink sub-band and guard band are determined, the remaining PRBs corresponding to the SBFD symbols belong to the uplink sub-band. That is, the quantity and frequency domain location of the PRBs in the uplink sub-band can be determined after determining the quantity and frequency domain location of the PRBs in the downlink sub-band and guard band. For example, if the bandwidth of the first time-frequency resource is the bandwidth of k carriers, the remaining PRBs in the k carriers excluding the downlink sub-band and guard band belong to the uplink sub-band, where k≥1. Or, if the bandwidth of the first time-frequency resource is the bandwidth of a BWP, the remaining PRBs in this BWP excluding the downlink sub-band and guard band belong to the uplink sub-band.

[0215] In some embodiments, the first signaling indicates the frequency domain location and the number of frequency domain units of the downlink resource. The frequency domain location of the downlink resource may include, for example, the frequency domain start location, and / or the frequency domain end location, and / or the frequency domain center location of the downlink resource.

[0216] For example, the first signaling indicates the frequency domain location and the number M of PRBs in the downlink sub-band. Assume the number of PRBs in the guard band in period 2 is the same as in period 1, and the distribution of the guard band on both sides of the downlink sub-band in period 2 is consistent with the distribution of the guard band on both sides of the downlink sub-band in period 1. For instance, the guard band includes b PRBs below the frequency domain start position of the downlink sub-band and / or a PRBs above the frequency domain end position of the downlink sub-band, where a and b may have the same or different values, where a is an integer greater than or equal to 1, and b is an integer greater than or equal to 1. Then, the UE can determine the time-frequency resource pattern of period 2 based on the indication of the first signaling and the number and distribution of the guard bands.

[0217] Therefore, when the first signaling indicates the frequency domain location and PRB quantity of the downlink resource, since the guard band quantity information is known (predefined, configured by the network device, or associated in period 1 and period 2), and the guard band is located on both sides or one side of the downlink resource's frequency domain, the UE can determine the first time-frequency resource in period 2 according to the indication of the first signaling. It can be understood that after the PRB quantity and frequency domain location of the downlink sub-band and guard band are determined, the remaining PRBs corresponding to the SBFD symbols belong to the uplink sub-band. That is, the PRB quantity and frequency domain location of the uplink sub-band can be determined after determining the PRB quantity and frequency domain location of the downlink sub-band and guard band. For example, if the bandwidth of the first time-frequency resource is the bandwidth of k carriers, the remaining PRBs in the k carriers excluding the downlink sub-band and guard band belong to the uplink sub-band, where k≥1. Or, if the bandwidth of the first time-frequency resource is the bandwidth of a BWP, the remaining PRBs in this BWP excluding the downlink sub-band and guard band belong to the uplink sub-band.

[0218] In some embodiments, the first signaling indicates information about the number of guard bands, the frequency domain location of the downlink resource, and the number of frequency domain cells. The information about the number of guard bands includes: the total number of PRBs in the guard band, and / or the number of PRBs distributed along the sides of the downlink resource. The frequency domain location of the downlink resource includes: the frequency domain start position, and / or the frequency domain end position, and / or the frequency domain center position of the downlink resource.

[0219] For example, the first signaling indicates that the protection band includes b PRBs below the frequency domain start position of the downlink subband and / or a PRBs above the frequency domain end position of the downlink subband, and indicates the frequency domain position of the downlink subband and the number of PRBs M. a and b may have the same or different values, where a is an integer greater than or equal to 1 and b is an integer greater than or equal to 1. Then, the UE can determine the time-frequency resource pattern for period 2 based on the indication of the first signaling.

[0220] Therefore, given the information on the number of guard bands, the frequency domain location of downlink resources, and the number of PRBs in the first signaling instruction, the guard band may be located on either side or on one side of the downlink resources in the frequency domain. The UE can then determine the first time-frequency resource in period 2 based on the first signaling instruction. It can be understood that after the number and frequency domain location of PRBs in the downlink sub-band and guard band are determined, the remaining PRBs corresponding to the SBFD symbols belong to the uplink sub-band. In other words, the number and frequency domain location of PRBs in the uplink sub-band can be determined after determining the number and frequency domain location of PRBs in the downlink sub-band and guard band. For example, if the bandwidth of the first time-frequency resource is the bandwidth of k carriers, the remaining PRBs in those k carriers, excluding the downlink sub-band and guard band, belong to the uplink sub-band, where k ≥ 1. Or, if the bandwidth of the first time-frequency resource is the bandwidth of a BWP, the remaining PRBs in that BWP, excluding the downlink sub-band and guard band, belong to the uplink sub-band.

[0221] Figure 14 illustrates a schematic diagram of a first time unit provided in an exemplary embodiment of this application. The frequency domain resources corresponding to the first time unit include flexible resources, which are used for downlink or uplink transmission. Furthermore, a guard band exists between the flexible resources and both the uplink and downlink resources. The flexible resources may be located in the middle or edge portion of the frequency domain resources corresponding to the first time unit. The flexible resources can also be referred to as flexible sub-bands, the uplink resources as uplink sub-bands, and the downlink resources as downlink sub-bands.

[0222] In Figure 14(a), the flexible resource is located in the middle part of the frequency domain resource corresponding to the first time unit, and the upper and lower edges of the frequency domain resource corresponding to the first time unit are both downlink resources. In Figure 14(b), the flexible resource is located in the upper edge of the frequency domain resource corresponding to the first time unit, and the lower edge of the frequency domain resource corresponding to the first time unit is a downlink resource. In Figure 14(c), the flexible resource is located in the lower edge of the frequency domain resource corresponding to the first time unit, and the upper edge of the frequency domain resource corresponding to the first time unit is a downlink resource. In Figure 14(d), the flexible resource is located in the middle part of the frequency domain resource corresponding to the first time unit, and the upper and lower edges of the frequency domain resource corresponding to the first time unit are both uplink resources. In Figure 14(e), the flexible resource is located in the upper edge of the frequency domain resource corresponding to the first time unit, and the lower edge of the frequency domain resource corresponding to the first time unit is an uplink resource. In Figure 14(f), the flexible resource is located in the lower edge of the frequency domain resource corresponding to the first time unit, and the upper edge of the frequency domain resource corresponding to the first time unit is an uplink resource.

[0223] In Figure 14(g), the frequency domain resources corresponding to the first time unit include flexible resources, uplink resources, downlink resources, and a guard band, with frequencies ranging from high to low as flexible resources, uplink resources, and downlink resources. Optionally, a guard band exists between flexible resources and uplink resources. Optionally, a guard band exists between uplink resources and downlink resources.

[0224] In Figure 14(h), the frequency domain resources corresponding to the first time unit include flexible resources, uplink resources, downlink resources, and a guard band, with frequencies ranging from high to low as uplink resources, downlink resources, and flexible resources. Optionally, a guard band exists between uplink resources and downlink resources. Optionally, a guard band exists between downlink resources and flexible resources.

[0225] The first time unit shown in Figure 14 is applicable to the embodiments shown in Figures 6 to 9. The network device can indicate at least one first time unit via first signaling, and the UE can determine the time domain location, number of time units, frequency domain location, and number of frequency domain units of at least one first time unit via first signaling. Furthermore, the uplink resources, downlink resources, and guard bands corresponding to different first time units may be the same or different; that is, the structures of the multiple first time units indicated by the first signaling may be the same or different. The first time unit is an SBFD symbol, or an SBFD symbol group, or an SBFD time slot, or an SBFD subframe, or an SBFD sub-time slot, or an SBFD frame.

[0226] Taking the first time unit shown in Figure 14 as an example, which is an SBFD symbol, Figure 15 shows a schematic diagram of time-frequency resources including at least one first time unit. It is assumed that all symbols in the first time-frequency resource are SBFD symbols, that is, at least one SBFD symbol indicated by the first signaling is all the symbols in the first time-frequency resource.

[0227] The network device sends a first signaling message, which indicates at least one SBFD symbol. This can also be understood as indicating a first time-frequency resource. The first time-frequency resource is the time-frequency resource included in period 2 of the diagram; therefore, each symbol included in period 2 is an SBFD symbol.

[0228] In some embodiments, before the network device sends the first signaling, a second time-frequency resource exists in the system, which is different from the first time-frequency resource. The second time-frequency resource is the time-frequency resource included in period 1 in the figure. The design of the second time-frequency resource can refer to the relevant content in steps 820 and 920, which will not be repeated here. Figure 15(a) takes the example that some symbols in the second time-frequency resource are SBFD symbols. The frequency domain resources corresponding to each SBFD symbol in period 1 include uplink resources and downlink resources.

[0229] In some embodiments, the network device configures or pre-configures the time-domain and / or frequency-domain locations of flexible resources in the first time-frequency resources. For example, a portion of the frequency-domain resources corresponding to the first time slot in the network device configuration or pre-configuration period is a flexible sub-band. For example, the frequency-domain resources corresponding to each time slot in the network device configuration or pre-configuration period include flexible sub-bands. For example, the x highest-frequency PRBs corresponding to each symbol in the network device configuration or pre-configuration period are flexible sub-bands. For example, the x PRBs at the center of the frequency domain corresponding to each symbol in the network device configuration or pre-configuration period are flexible sub-bands. For example, the x lowest-frequency PRBs corresponding to each symbol in the network device configuration or pre-configuration period are flexible sub-bands. In this case, the first signaling does not need to indicate the time-frequency domain location information of the flexible resources.

[0230] As shown in Figure 15(a), the frequency domain resources corresponding to the first time slot in the network device configuration or pre-configuration cycle are flexible subbands. Therefore, the frequency domain resources corresponding to time slots 0 and 5 include flexible subbands. The network device indicates the frequency domain start position and the number of frequency domain units of the flexible subband. Optionally, the network device also indicates the number of guard bands, for example, the guard band includes b PRBs below the frequency domain start position of the flexible subband and / or a PRBs above the frequency domain end position of the flexible subband, where a and b have the same or different values, a is an integer greater than or equal to 1, and b is an integer greater than or equal to 1. Assume that the frequency domain start position and the number of PRBs of the flexible subband in the first time-frequency resource are the same as those of the flexible subband in the second time-frequency resource. The network device sends a first signaling indicating that the transmission direction of the flexible subband corresponding to time slot 0 is downlink. Accordingly, the guard band between the flexible subband and the downlink subband is also used for downlink transmission. The network device sends the first signaling to indicate that the transmission direction of the flexible subband corresponding to time slot 5 is uplink. Therefore, each symbol in time slot 5 is an SBFD symbol, which means that the frequency domain resources corresponding to each symbol in time slot 5 include uplink resources and downlink resources.

[0231] When flexible resources are used for downlink transmission, the guard band between the flexible resources and downlink resources is also used for downlink transmission. That is, if the frequency domain resources corresponding to a time unit include both flexible resources and downlink resources, and there is only a guard band between the flexible resources and downlink resources, and the flexible resources are also used for downlink transmission, then the guard band between the flexible resources and downlink resources is also used for downlink transmission, resulting in a larger downlink resource formed by the adjacent flexible resources, guard band, and downlink resources in the frequency domain, as shown in Figures 16(a) and (b). Similarly, when flexible resources are used for uplink transmission, the guard band between the flexible resources and uplink resources is also used for uplink transmission. That is, if the frequency domain resources corresponding to a time unit include both flexible resources and uplink resources, and there is only a guard band between the flexible resources and uplink resources, and the flexible resources are also used for uplink transmission, then the guard band between the flexible resources and uplink resources is also used for uplink transmission, resulting in a larger uplink resource formed by the adjacent flexible resources, guard band, and uplink resources in the frequency domain, as shown in Figures 16(c) and (d).

[0232] In some embodiments, the network device configures or pre-configures the frequency domain positional relationship between flexible resources and uplink resources in the first time-frequency resources. For example, the frequency domain resources above the uplink sub-band corresponding to each OFDM symbol in the network device configuration or pre-configuration period are flexible resources. That is, the flexible sub-band is located above the frequency domain end position of the uplink sub-band, and there is a guard band between the flexible sub-band and the uplink sub-band.

[0233] Referring to Figure 15(b), assume that the frequency domain resources above the uplink subband corresponding to each OFDM symbol in each period are configured as flexible subbands. The network device sends a first signaling instruction indicating that the transmission direction of the flexible subband in time slots 0 to 4 of period 1 is downlink. Therefore, the frequency domain resources corresponding to each symbol in time slots 0 to 4 include both uplink and downlink resources. The network device sends a first signaling instruction indicating that the transmission direction of the flexible subband in time slots 5 to 9 of period 2 is uplink. The frequency domain starting positions of the flexible subbands in period 1 and period 2 are the same. The number of PRBs for uplink resources in period 2 is greater than that in period 1. Furthermore, the guard band between the flexible subband and the uplink subband is also used for uplink transmission. Therefore, the uplink subband, guard band, and flexible subband in period 2 form continuous uplink resources.

[0234] In some embodiments, the network device configures or pre-configures the frequency domain positional relationship between flexible resources and downlink resources in the first time-frequency resources. For example, the frequency domain resources below the downlink sub-band corresponding to each OFDM symbol in the network device configuration or pre-configuration period are flexible resources. That is, the flexible sub-band is located below the frequency domain start position of the downlink sub-band, and there is a guard band between the flexible sub-band and the downlink sub-band.

[0235] Referring to Figure 15(c), assume that the frequency domain resources under the downlink subband corresponding to each OFDM symbol in each period are configured as flexible subbands. The network device sends a first signaling instruction indicating that the transmission direction of the flexible subbands in time slots 0-4 of period 1 is downlink. Correspondingly, the guard band between the flexible subbands and the downlink subbands is also used for downlink transmission. Therefore, the frequency domain resources corresponding to each symbol in time slots 0-4 are used only for downlink transmission. The network device sends a first signaling instruction indicating that the transmission direction of the flexible subbands in time slots 5-9 of period 2 is uplink. Therefore, the frequency domain resources corresponding to each symbol in time slots 5-9 include both uplink and downlink resources.

[0236] In some embodiments, the network device indicates the number of PRBs and / or the frequency domain position (including the frequency domain start position and / or the frequency domain end position) of the flexible subband, and also indicates the transmission direction of the flexible subband. For example, the network device indicates the number of PRBs and / or the frequency domain start position of the flexible subband via a first signaling signal, and indicates the transmission direction of the flexible subband via a second signaling signal. For example, the network device indicates the number of PRBs and / or the frequency domain start position of the flexible subband via the first signaling signal, and also indicates the transmission direction of the flexible subband via the first signaling signal.

[0237] In some embodiments, the first signaling indicates one or more of the following: the transmission direction of the flexible resources, the quantity information of the flexible resources, the frequency domain location information of the flexible resources, the quantity information of the guard band, and the frequency domain location information of the guard band.

[0238] For example, the network device configures or pre-configures the frequency domain end position of the flexible resource in the first time-frequency resource. The first signaling may indicate the transmission direction, the number of PRBs, and / or the frequency domain start position of the flexible resource; or, the first signaling may indicate the number of PRBs and / or the frequency domain start position of the flexible resource, and the second signaling may indicate the transmission direction of the flexible resource.

[0239] For example, the network device configures or pre-configures the frequency domain start position of the flexible resource in the first time-frequency resource. The first signaling may indicate the transmission direction, the number of PRBs, and / or the frequency domain end position of the flexible resource; or, the first signaling may indicate the number of PRBs and / or the frequency domain end position of the flexible resource, and the second signaling may indicate the transmission direction of the flexible resource.

[0240] For example, the network device configures or pre-configures the number of PRBs for flexible resources in the first time-frequency resource. The first signaling may indicate the transmission direction, frequency domain start position, and / or frequency domain end position of the flexible resource; or, the first signaling may indicate the frequency domain start position and / or frequency domain end position of the flexible resource, and the second signaling may indicate the transmission direction of the flexible resource.

[0241] In some embodiments, the first signaling indicates an identifier / index / number corresponding to at least one first time unit, or the first signaling indicates an identifier / index / number of a first time-frequency resource. Different identifiers / indexes / numbers correspond to different time-frequency resource patterns. Therefore, the UE can determine the time-frequency resource pattern for period 2 according to the indication of the first signaling.

[0242] For example, the communication protocol defines a mapping relationship between a set of identifiers and resource information; alternatively, the network device configures a mapping relationship between identifiers and resource information; or, a mapping relationship between identifiers and resource information is pre-configured. The resource information includes one or more of the following: the quantity of uplink resources, the frequency domain location of uplink resources, the quantity of guard bands, the frequency domain location of guard bands, the quantity of downlink resources, and the frequency domain location within downlink resources. The specific meanings of each resource information item are described above.

[0243] For example, if the identifier has a mapping relationship (also understood as "association") with the number of PRBs and the frequency domain position of the uplink sub-band, then the UE can uniquely determine the number of PRBs and the frequency domain position of the uplink sub-band in period 2 through the identifier indicated by the first signaling. Similarly, if the identifier has a mapping relationship with the number of PRBs, the frequency domain position of the uplink sub-band, and the number of guard bands, then the UE can uniquely determine the number of guard bands, the number of PRBs, and the frequency domain position of the uplink sub-band in period 2 through the identifier indicated by the first signaling. Likewise, if the identifier has a mapping relationship with the number of PRBs and the frequency domain position of the downlink sub-band, then the UE can uniquely determine the number of PRBs and the frequency domain position of the downlink sub-band in period 2 through the identifier indicated by the first signaling. For example, if there is a mapping relationship between the identifier and the transmission direction of the flexible sub-band, the UE can uniquely determine the transmission direction of the flexible sub-band in period 2 through the identifier indicated by the first signaling. For example, if there is a mapping relationship between the identifier and the number of PRBs and the frequency domain position of the flexible sub-band, the UE can uniquely determine the number of PRBs and the frequency domain position of the flexible sub-band in period 2 through the identifier indicated by the first signaling. For example, if there is a mapping relationship between the identifier and the number of PRBs, the frequency domain position of the flexible sub-band, and the number of guard bands, the UE can uniquely determine the number of guard bands, the number of PRBs, and the frequency domain position of the flexible sub-band in period 2 through the identifier indicated by the first signaling. For example, if there is a mapping relationship (or association) between the identifier and the time-frequency resource pattern, the UE can uniquely determine the time-frequency resource pattern in period 2 through the identifier indicated by the first signaling.

[0244] The above examples all assume that at least one SBFD symbol indicated by the first signaling is all the symbols in the first time-frequency resource. In fact, the above content also applies to the case where at least one SBFD symbol indicated by the first signaling is some of the symbols in the first time-frequency resource, as shown in the time-frequency resource diagram in Figure 17.

[0245] The network device sends a first signaling message, which indicates at least one SBFD symbol. The at least one SBFD symbol indicated by the first signaling message is a subset of the symbols in period 2. That is, period 2 in Figure 17 includes both at least one SBFD symbol and at least one non-SBFD symbol (which can also be understood as a legacy symbol). The frequency domain resources corresponding to each SBFD symbol include uplink resources, downlink resources, and a guard band. The frequency domain resources corresponding to non-SBFD symbols include only uplink resources or only downlink resources. For example, time slots 6, 7, and 8 in period 2 include all SBFD symbols, time slot 5 includes all downlink symbols, and time slot 9 includes all uplink symbols.

[0246] In some embodiments, before the network device sends the first signaling, a second time-frequency resource exists in the system, which is different from the first time-frequency resource. The second time-frequency resource is the time-frequency resource included in period 1 of Figure 17. The design of the second time-frequency resource can refer to the relevant content in steps 820 and 920, which will not be repeated here. Figure 17 takes the example that some symbols in the second time-frequency resource are SBFD symbols. For example, the symbols included in time slots 1, 2 and 3 in period 1 are all SBFD symbols, the symbols included in time slot 0 are all downlink symbols, and the symbols included in time slot 4 are all uplink symbols.

[0247] In some embodiments, the first signaling indicates one or more of the following information: the quantity information of uplink resources corresponding to at least one SBFD symbol, the frequency domain location of the uplink resources corresponding to at least one SBFD symbol, the quantity information of guard bands corresponding to at least one SBFD symbol, the frequency domain location of guard bands corresponding to at least one SBFD symbol, the quantity information of downlink resources corresponding to at least one SBFD symbol, and the frequency domain location within the downlink resources corresponding to at least one SBFD symbol. The specific design of each piece of information is as described above.

[0248] It is important to emphasize that the first signaling instruction can only change the frequency domain information of SBFD symbols, and cannot change the frequency domain information of non-SBFD symbols. Referring to Figure 17, the first signaling dynamically adjusts the pattern of period 1 to the pattern of period 2 by adjusting the uplink sub-band, downlink sub-band, and guard band corresponding to time slots 1, 2, and 3 to the uplink sub-band, downlink sub-band, and guard band corresponding to time slots 6, 7, and 8.

[0249] For example, in Figure 17(a), the uplink subband corresponding to the SBFD symbol in period 1 includes N1 PRBs, and the uplink subband corresponding to the SBFD symbol in period 2 includes N PRBs, where N > N1. Furthermore, the frequency domain end position of the uplink subband corresponding to the SBFD symbol in period 1 is the same as the frequency domain end position of the uplink subband corresponding to the SBFD symbol in period 2. Also, the number of guard bands corresponding to the SBFD symbol in period 1 is consistent with the number of guard bands corresponding to the SBFD symbol in period 2. Each guard band includes b PRBs below the frequency domain start position of the uplink subband and / or a PRBs above the frequency domain end position of the uplink subband. The values ​​of a and b may be the same or different, where a is an integer greater than or equal to 1, and b is an integer greater than or equal to 1.

[0250] For example, in Figure 17(b), the number of PRBs in the uplink subband corresponding to the SBFD symbol in period 1 is the same as the number of PRBs in the uplink subband corresponding to the SBFD symbol in period 2. Furthermore, the first signaling indicates that the frequency domain start position of the uplink subband corresponding to the SBFD symbol in period 2 is F_start. Also, the number of guard bands corresponding to the SBFD symbol in period 1 is consistent with the number of guard bands corresponding to the SBFD symbol in period 2. Each guard band includes b PRBs below the frequency domain start position of the uplink subband and / or a PRBs above the frequency domain end position of the uplink subband. The values ​​of a and b may be the same or different, where a is an integer greater than or equal to 1, and b is an integer greater than or equal to 1.

[0251] Furthermore, regardless of whether the at least one SBFD symbol indicated by the first signaling is all the symbols in the first time-frequency resource, the period of the second time-frequency resource can be the same as or different from that of the first time-frequency resource. Assuming the period of the second time-frequency resource is P2 and the period of the first time-frequency resource is P1, then P2 and P1 can be the same or different. If P2 = P1, it means that the duration of the first time-frequency resource is the same as that of the second time-frequency resource. If P2 ≠ P1, it means that the duration of the first time-frequency resource is different from that of the second time-frequency resource, and P2 is less than or greater than P1. Before the network device sends the first signaling, the second time-frequency resource repeats in the time domain with a period of P2. After the network device sends the first signaling, the first time-frequency resource repeats in the time domain with a period of P1.

[0252] In some embodiments, the period P1 of the first time-frequency resource is a default (e.g., default P1 = P2, or P1 < P2, P2 < P1), or it is agreed upon by the communication protocol, or it is indicated by the network device (also indicated by the first signaling, or indicated separately), or it is determined by the UE (e.g., determined according to predefined rules), or the period P1 of the first time-frequency resource is associated with the period P2 of the second time-frequency resource.

[0253] In some embodiments, regardless of whether P1 and P2 are the same, the number of first time units included in the first time-frequency resource and the number of first time units included in the second time-frequency resource can be the same or different. That is, the number of SBFD symbols in the first time-frequency resource and the number of SBFD symbols in the second time-frequency resource can be the same or different.

[0254] Figure 18 shows a structural block diagram of a resource indication device provided in an exemplary embodiment of this application. This device can be implemented as a network device as described above, or as part of a network device as described above. The device includes a transmission module 1810.

[0255] The transmitting module 1810 is configured to: transmit a first signaling, wherein the first signaling indicates at least one first time unit, and the frequency domain resources corresponding to the first time unit include uplink resources and downlink resources.
