[0050] First, the relevant technologies involved in the embodiments of this application will be introduced:

[0051] New Radio (NR) frame structure

[0052] In 5G NR systems, to better meet the needs of different deployment scenarios and services, flexible subcarrier spacing (15kHz, 30kHz, and 60kHz below 6GHz, and 60kHz, 120kHz, and 240kHz above 6GHz) and flexible uplink / downlink handover cycles (including semi-static uplink / downlink handover cycles of 0.5ms, 1ms, 2ms, 5ms, and 10ms, as well as handover cycles of 0.625ms, 1.25ms, and 2.5ms suitable for special subcarrier spacings) are supported. To accommodate the different service requirements of different terminals, 5G supports three signaling-level frame structure configuration and / or indication methods, including two semi-static frame structure configuration methods and one dynamic frame structure indication method.

[0053] Level 1: Community-specific uplink and downlink configuration (tdd-UL-DL-ConfigurationCommon);

[0054] Level 2: Terminal-specific uplink and downlink configuration (tdd-UL-DL-ConfigurationDedicated);

[0055] Level 3: Dynamic Resource Indicator (Slot Format Indicator, SFI)).

[0056] For Level 1:

[0057] Cell-specific uplink and downlink configurations are transmitted via system messages. Configuration parameters include one or more of the following: uplink / downlink switching period, reference subcarrier spacing, and uplink / downlink transmission configuration. The number of time slots within each period can be determined based on the reference subcarrier spacing configuration and the uplink / downlink switching period. Furthermore, the downlink and uplink transmission ratio within the uplink / downlink switching period can be determined based on the uplink / downlink transmission configuration. For cell-specific uplink / downlink configurations, the configured uplink / downlink transmission mode begins with downlink transmission (i.e., the total number of downlink time slots included from the beginning of the period, and the number of downlink symbols in the time slots after the last downlink time slot) and ends with uplink transmission (i.e., the total number of uplink time slots included counting backwards from the end of the period, and the number of uplink symbols in the time slot preceding the earliest uplink time slot). Unconfigured time-domain resources between downlink and uplink are considered flexible resources. Through cell-level semi-static frame structure configuration, a minimum set of fixed resource configurations can be achieved, suitable for idle users, enabling forward compatibility.

[0058] For Level 2:

[0059] Terminal-specific uplink and downlink configurations are indicated via user-specific Radio Resource Control (RRC) signaling. Terminal-specific uplink and downlink configurations can only further configure the flexible resources within the cell-specific uplink and downlink configurations. Based on a slot-by-slot indication method, the signaling configuration includes a slot index and the uplink and downlink transmission methods for the indicated slots. Specific transmission methods include one or more of the following:

[0060] • All downlink time slots;

[0061] • All uplink time slots;

[0062] • Partial downlink / uplink time slots; specifically, this includes the number of downlink symbols and the number of uplink symbols in the time slot.

[0063] By configuring the frame structure specifically for each terminal, frame structure transmission parameters can be configured according to the service characteristics and service requirements of different terminals, thus enabling user-centric resource configuration.

[0064] For Level 3:

[0065] Dynamic resource indication (DRI) is transmitted via the group common Physical Downlink Control Channel (PDCCH) and can dynamically indicate the transmission format of one or more time slots. For each symbol, DRI includes three states: Downlink (DL), Uplink (UL), and Flexible. A table is used to determine the corresponding time slot format for different values ​​(the proportions of DL, Flexible, and UL symbols vary in different time slot formats). This table has 256 rows, with the first 56 rows representing different time slot formats and the last 200 rows reserved. DRI enables real-time adjustment of the uplink and downlink transmission directions for each symbol, allowing for rapid adaptation to dynamic changes in service / interference and improving transmission efficiency.

[0066] Sub-band non-overlapping full duplex (SBFD) resource configuration

[0067] To overcome the problems of weak uplink coverage, high uplink latency, and insufficient uplink capacity caused by limited uplink resource allocation in NR Time Division Duplexing (TDD), the 3rd Generation Partnership Project (3GPP) introduced X Division Duplex (XDD) technology in Release 18 (R18). This technology allows data to be transmitted and received simultaneously on different subbands of the same subframe / slot / symbol. This technology is mainly used on the base station side, while the terminal side still maintains a half-duplex state, that is, only transmitting or receiving data is supported within a subframe / slot / symbol.

[0068] NR only supports SBFD time-domain resource configuration and frequency-domain resource configuration specific to semi-static cells:

[0069] SBFD Time Domain Resource Configuration: NR supports configuring uplink subbands (UL subband) and downlink subbands (DL subband) in the downlink symbols and flexible symbols corresponding to the cell-specific TDD configuration, as shown in Figure 1. The time domain position of the SBFD subband (including UL subband and DL subband) is configured within a certain period. The SBFD period is consistent with the TDD period, and the SBFD symbols (symbols configured with SBFD subbands) are continuous within a TDD period. They can start and end at any downlink symbol or flexible symbol. The configuration parameters include the start time slot of SBFD, the start symbol in the start time slot, the end time slot of SBFD, and the end symbol in the end time slot.

[0070] SBFD frequency domain resource configuration: For the sake of simplicity in network / terminal implementation, NR restricts the frequency domain resources of UL subband and DL subband for different SBFD symbols to be the same. The start resource block (RB) and number of RBs for uplink and downlink subbands are configured per carrier in the form of Start and Length Indicator Value (SLIV).

[0071] For terminal behavior on SBFD symbols, NR specifies:

[0072] • UL transmission can only occur within UL subbands; UL transmission outside of UL subbands is not permitted.

[0073] • DL reception can only occur within the DL subband; DL reception outside the DL subband is not allowed.

[0074] That is, once a flexible symbol in the TDD configuration is configured with an SBFD subband, even though the symbol is a flexible symbol, its transmission direction can no longer be changed by the terminal-specific TDD configuration and dynamic resource indication.

[0075] Figure 2 shows a schematic diagram of a communication system provided in an exemplary embodiment of this application. The communication system includes a terminal device 110 and a network device 120.

[0076] The terminal device 110 in this application embodiment can also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user apparatus. This terminal includes, but is not limited to: handheld devices, wearable devices, in-vehicle devices, and IoT devices, such as: mobile phones, tablets, e-readers, laptops, desktop computers, televisions, game consoles, mobile internet devices (MID), augmented reality (AR) terminals, virtual reality (VR) terminals, mixed reality (MR) terminals, wearable devices, controllers, electronic tags, controllers, wireless terminals in industrial control, self-driving, remote medical, smart grid, transportation safety, smart city, smart home, remote medical surgery, cellular phones, cordless phones, Session Initiation Protocol (SIP) phones, and wireless local loops.

B, gNB) or transmission point (TRP or TP), or, in a 5G system, one or a group of antenna panels (including multiple antenna panels) of a base station, or, network nodes constituting a gNB or transmission point, such as baseband unit (BBU) or distributed unit (DU), or base stations in Beyond Fifth Generation (B5G) mobile communication systems or 6th Generation (6G) mobile communication systems, or core network (CN), fronthaul, backhaul, radio access network (RAN), network slicing, etc., or serving cell, primary cell (PCell), primary secondary cell (PSCell), special cell (SpCell), secondary cell (SCell), neighboring cell, etc. of terminal equipment.

[0078] Terminal device 110 and network device 120 communicate with each other via some air interface technology. For example, there are two communication scenarios between terminal device 110 and network device 120: uplink communication scenario and downlink communication scenario. Uplink communication refers to terminal device 110 sending signals to network device 120; downlink communication refers to network device 120 sending signals to terminal device 110.

[0079] The technical solutions provided in the embodiments of this application can be applied to various communication systems, such as: Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Advanced Long Term Evolution (LTE-A) systems, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication systems, 5G mobile communication systems, NR systems, evolution systems of NR systems, LTE-based access to unlicensed spectrum (LTE-U) systems, NR-based access to unlicensed spectrum (NR-U) systems, Terrestrial Networks (TN) systems, Non-Terrestrial Networks (NTN) systems, and Wireless Local Area Networks (WLANs). Networks (WLAN), Wi-Fi, cellular IoT systems, cellular passive IoT systems, and can also be applied to subsequent evolution systems of 5G NR systems, as well as B5G, 6G and subsequent evolution systems.

[0080] In some embodiments of this application, "NR" may also be referred to as a 5G NR system or a 5G system. The 5G mobile communication system may include Non-Standalone (NSA) and / or Standalone (SA) networking. The technical solutions provided in the embodiments of this application can also be applied to Machine-Type Communication (MTC), Long Term Evolution-Machine (LTE-M) technology, Device-to-Device (D2D) networks, Machine-to-Machine (M2M) networks, Internet of Things (IoT) networks, or other networks. For example, an IoT network may include a vehicle-to-everything (V2X) network. In this context, the communication methods in the vehicle-to-everything (V2X) system are collectively referred to as vehicle to other devices (V2X, where X can represent anything). For example, V2X can include: vehicle to vehicle (V2V) communication, vehicle to infrastructure (V2I) communication, vehicle to pedestrian (V2P) communication, or vehicle to network (V2N) communication, etc.

[0081] It should be understood that in the description of the embodiments of this application, the term "correspondence" can indicate a direct or indirect correspondence between two things, or an association between them, or a relationship of instruction and being instructed, configuration and being configured, etc. In the embodiments of this application, "predefined" can be implemented by pre-storing corresponding codes, tables, or other means that can be used to indicate relevant information in the device (e.g., including terminal devices and network devices), and this application does not limit the specific implementation method. For example, predefined can refer to what is defined in a protocol. In the embodiments of this application, "protocol" can refer to standard protocols in the field of communication, such as LTE protocol, NR protocol, Internet of Things protocol, and related protocols applied to future communication systems, and this application does not limit it.

[0082] As can be seen from the aforementioned technologies, considering the service characteristics and needs of different regions and terminals, NR TDD supports three signaling-level frame structure configuration and / or indication methods, including two semi-static frame structure configuration methods (cell-specific uplink / downlink configuration and UE-specific uplink / downlink configuration) and one dynamic frame structure indication method (dynamic SFI indication). To overcome the problems of weak uplink coverage, high uplink latency, and insufficient uplink capacity caused by limited uplink resource allocation in NR TDD, SBFD was introduced in the relevant technologies. However, due to the need to consider the compatibility of SBFD and TDD, only cell-specific semi-static SBFD configuration, i.e., level one configuration, is supported.

[0083] Considering the greater uncertainty in the service characteristics, distribution, and proportion of future communication systems (such as 6G), and the necessity of forward compatibility, multi-level SBFD configuration and / or indications are essential. Once both TDD and SBFD support multi-level indications, the interoperability between the two sets of configurations and / or indications will become more complex during the standardization process, introducing many priority issues. Therefore, simplifying configuration and reducing the complexity of standardization discussions is crucial.

[0084] Based on this, this application proposes a method for configuring the transmission direction. By directly indicating the two-dimensional transmission direction, the interoperability discussion between the time-domain transmission direction and the frequency-domain transmission direction is reduced, which helps to reduce the complexity of standard discussions.

[0085] Figure 3 illustrates a flowchart of a transmission direction configuration method provided in an exemplary embodiment of this application. The method is executed by a terminal device and includes:

[0086] Step 220: The terminal device receives first configuration information, which is used to configure the transmission direction of one or more resource blocks.

[0087] In some embodiments, the first configuration information includes: cell-specific configuration information and / or terminal-specific configuration information. The cell-specific configuration information enables fixed resource configuration, is applicable to idle users, and allows for forward compatibility; the terminal-specific configuration information enables transmission direction indication based on the terminal's service characteristics and service ratio, achieving user-centric resource configuration.

[0088] Optionally, cell-specific configuration information is configured via broadcast information, such as the Master Information Block (MIB) and / or the System Information Block (SIB).

[0089] Optionally, terminal-specific configuration information is configured by terminal-specific Radio Resource Control (RRC) signaling.

[0090] In some embodiments, each resource block in one or more resource blocks includes one or more time units in the time domain and one or more frequency units in the frequency domain. Alternatively, it can be understood that the "resource block" described in the embodiments of this application is a two-dimensional resource block including both time and frequency domain dimensions.

[0091] Optionally, each resource block includes one or more time units in the time domain and at least two frequency units in the frequency domain. Alternatively, each resource block includes at least two time units in the time domain and one or more frequency units in the frequency domain. In particular, if a resource block includes one time unit in the time domain and one frequency unit in the frequency domain, then the resource block constitutes one time-frequency unit.

[0092] In some embodiments, different resource blocks may include the same or different numbers of time units in the time domain. Different resource blocks may also include the same or different numbers of frequency units in the frequency domain. For example, as shown in FIG4, resource block 1 includes 3 time units in the time domain and 3 frequency units in the frequency domain. Resource block 2 includes 2 time units in the time domain and 3 frequency units in the frequency domain.

[0093] In some embodiments, a time unit includes one or more of the following: a symbol, a symbol group, a sub-slot, a slot, a subframe, and a frame.

[0094] In some embodiments, the frequency domain unit includes one or more of the following: resource element (RE), RE group, resource block (RB), RB group, subband, bandwidth part (BWP), and carrier.

[0095] Optionally, a "resource block" can also be called a "transmission resource block" or a "time-frequency resource block". In this embodiment, only the term "resource block" is used as an example for illustration.

[0096] In some embodiments, the transmission direction of the resource block includes one or more of the following: downlink, uplink, flexible, full-duplex, reserved, and guard band.

[0097] Optionally, "the first configuration information is used to configure the transmission direction of one or more resource blocks" can also be understood as "the first configuration information is used to configure the resource type of one or more resource blocks". Further, the resource type includes one or more of the following: downlink resources, uplink resources, flexible resources, duplex resources, reserved resources, and guard band resources. Among these, flexible resources can better achieve the purpose of allocating resources according to dynamic changes in services; reserved resources can achieve a function similar to semi-static BWP handover and also achieve forward compatibility; duplex resources can perform both uplink and downlink transmission, making them true full-duplex resources with the highest resource utilization; guard band resources can be configured between resources in different transmission directions to reduce interference.

[0098] In some embodiments, the terminal device does not expect conflicts between cell-specific configuration information and terminal-device-specific configuration information. Such conflicts include situations where the cell-specific configuration information configures the transmission direction of one or more resource blocks as a first direction, while the terminal-device-specific configuration information configures the transmission direction of one or more resource blocks as a second direction, and the first and second directions are different. For example, the cell-specific configuration information configures the transmission direction of one or more resource blocks as uplink, while the terminal-device-specific configuration information configures the transmission direction of one or more resource blocks as downlink. Another example is that the cell-specific configuration information configures the transmission direction of one or more resource blocks as downlink, while the terminal-device-specific configuration information configures the transmission direction of one or more resource blocks as uplink.

[0099] In some embodiments, when there is a conflict between the cell-specific configuration information and the terminal device-specific configuration information, the transmission direction of the resource block or the terminal behavior on the resource block is determined according to the indication of the terminal device-specific configuration information. If the cell-specific configuration information is used to configure the transmission direction of one or more resource blocks as a first direction, and the terminal device-specific configuration information is used to configure the transmission direction of one or more resource blocks as a second direction, the transmission direction of one or more resource blocks is determined to be the second direction, or the terminal device performs transmission according to the second direction in one or more resource blocks. For example, if the cell-specific configuration information is used to configure the transmission direction of one or more resource blocks as uplink, and the terminal device-specific configuration information is used to configure the transmission direction of one or more resource blocks as downlink, the transmission direction of one or more resource blocks is determined to be downlink, or the terminal device performs downlink reception in one or more resource blocks, and / or does not perform uplink transmission.

[0100] In some embodiments, since the "resource block" in this application is a two-dimensional resource block including both time and frequency domains, the "transmission direction of the resource block" is also a two-dimensional transmission direction including both time and frequency domains.

[0101] In summary, the method provided in this embodiment enables direct configuration of the transmission direction corresponding to the two-dimensional resource block through the first configuration information. That is, configuration in both the time domain and frequency domain can be achieved with a single configuration, without the need for dual configuration in the time domain and frequency domain. This helps to avoid interoperability discussions between the time domain and frequency domain, thereby reducing standard complexity.

[0102] Figure 5 illustrates a flowchart of a transmission direction configuration method provided in an exemplary embodiment of this application. The method is executed by a network device and includes:

[0103] Step 320: The network device sends first configuration information, which is used to configure the transmission direction of one or more resource blocks.

[0104] In some embodiments, the first configuration information includes: cell-specific configuration information and / or terminal-specific configuration information. The cell-specific configuration information enables fixed resource configuration, is applicable to idle users, and allows for forward compatibility; the terminal-specific configuration information enables transmission direction indication based on the terminal's service characteristics and service ratio, achieving user-centric resource configuration.

[0105] Optionally, cell-specific configuration information can be configured via broadcast information, such as MIB and / or SIB.

[0106] Optionally, terminal-specific configuration information is configured via terminal-specific RRC signaling.

[0107] In some embodiments, each resource block in one or more resource blocks includes one or more time units in the time domain and one or more frequency units in the frequency domain. Alternatively, it can be understood that the "resource block" described in the embodiments of this application is a two-dimensional resource block including both time and frequency domain dimensions.

[0108] Optionally, each resource block includes one or more time units in the time domain and at least two frequency units in the frequency domain. Alternatively, each resource block includes at least two time units in the time domain and one or more frequency units in the frequency domain. In particular, if a resource block includes one time unit in the time domain and one frequency unit in the frequency domain, then the resource block constitutes one time-frequency unit.

[0109] In some embodiments, different resource blocks may include the same or different numbers of time units in the time domain. Different resource blocks may also include the same or different numbers of frequency units in the frequency domain. For example, as shown in FIG4, resource block 1 includes 3 time units in the time domain and 3 frequency units in the frequency domain. Resource block 2 includes 2 time units in the time domain and 3 frequency units in the frequency domain.

[0110] In some embodiments, a time unit includes one or more of the following: a symbol, a symbol group, a sub-slot, a slot, a subframe, and a frame.

[0111] In some embodiments, the frequency domain unit includes one or more of the following: RE, RE group, RB, RB group, subband, BWP, and carrier.

[0112] Optionally, a "resource block" can also be called a "transmission resource block" or a "time-frequency resource block". In this embodiment, only the term "resource block" is used as an example for illustration.

[0113] In some embodiments, the transmission direction of the resource block includes one or more of the following: downlink, uplink, flexible, full-duplex, reserved, and guard band.

[0114] Optionally, "the first configuration information is used to configure the transmission direction of one or more resource blocks" can also be understood as "the first configuration information is used to configure the resource type of one or more resource blocks". Further, the resource type includes one or more of the following: downlink resources, uplink resources, flexible resources, duplex resources, reserved resources, and guard band resources. Among these, flexible resources can better achieve the purpose of allocating resources according to dynamic changes in services; reserved resources can achieve a function similar to semi-static BWP handover and also achieve forward compatibility; duplex resources can perform both uplink and downlink transmission, making them true full-duplex resources with the highest resource utilization; guard band resources can be configured between resources in different transmission directions to reduce interference.

[0115] In some embodiments, since the "resource block" in this application is a two-dimensional resource block including both time and frequency domains, the "transmission direction of the resource block" is also a two-dimensional transmission direction including both time and frequency domains.

[0116] In summary, the method provided in this embodiment enables direct configuration of the two-dimensional transmission direction corresponding to the two-dimensional resource block through the first configuration information. That is, configuration in both the time domain and frequency domain can be achieved with a single configuration, without the need for dual configuration in the time domain and frequency domain. This helps to avoid interoperability discussions between the time domain and frequency domain, thereby reducing standard complexity.

[0117] 1. Regarding the first configuration information

[0118] The first configuration information is used to configure one or more of the following:

[0119] • The first cycle is the cycle used to indicate the transmission direction configuration of one or more resource blocks;

[0120] • Reference subcarrier spacing;

[0121] • The temporal scope of the first configuration information;

[0122] • The frequency domain scope of the first configuration information;

[0123] • The granularity of the first configuration information;

[0124] • The number of resource blocks.

[0125] 1.1 For the first cycle

[0126] The first cycle represents the time range during which the time-frequency two-dimensional transmission direction mode configured in the first configuration information repeats in the time domain.

[0127] For example, as shown in Figure 6, assuming that the first configuration information is used to configure the transmission direction of {resource block 1, resource block 2, resource block 3, resource block 4}, the first configuration information can also configure a first period, which is the period of repetition of the transmission direction of {resource block 1, resource block 2, resource block 3, resource block 4} in the time domain.

[0128] 1.2 Regarding the reference subcarrier spacing

[0129] In some embodiments, the reference subcarrier spacing includes a first reference subcarrier spacing, which corresponds to both the time domain and the frequency domain. The first reference subcarrier spacing is used to determine one or more of the following: the length of the time unit, the number of time units within the time domain range of the first period or the first configuration information (or the boundary of the time domain range of the first period or the first configuration information), the size of the frequency domain unit, and the number of frequency domain units within the frequency domain range of the first configuration information (or the boundary of the frequency domain range of the first configuration information).

[0130] Alternatively, it can be understood that the first configuration information configures only one reference subcarrier interval, which is shared by the time and frequency domains. This reference subcarrier interval is used to determine both the length of the time unit in the time domain (e.g., symbol length), the number of time units within the time domain scope of the first period or the first configuration information (e.g., number of symbols or number of time slots), and the size of the frequency unit in the frequency domain (e.g., size of RE or RB), and the number of frequency units within the frequency domain scope of the first configuration information (e.g., number of REs or number of RBs).

[0131] When the first configuration information only configures one reference subcarrier interval, it is beneficial to save configuration resources. However, since this one reference subcarrier interval is shared by the time domain and the frequency domain, it is impossible to achieve fine-grained resource configuration at both time and frequency.

[0132] In some embodiments, the reference subcarrier spacing includes a second reference subcarrier spacing and a third reference subcarrier spacing. The second reference subcarrier spacing corresponds to the time domain, and the third reference subcarrier spacing corresponds to the frequency domain. The second reference subcarrier spacing is used to determine the length of the time unit and / or the number of time units within the time domain range of the first period or the first configuration information (or the boundary of the time domain range of the first period or the first configuration information). The third reference subcarrier spacing is used to determine the size of the frequency domain unit and / or the number of frequency domain units within the frequency domain range of the first configuration information (or the boundary of the frequency domain range of the first configuration information).

[0133] Alternatively, the first configuration information can be understood as configuring the two reference subcarrier spacings. One reference subcarrier spacing corresponds to the time domain, or can be understood as determining the length and / or number of time units in the time domain. The other reference subcarrier spacing corresponds to the frequency domain, or can be understood as determining the size and / or number of frequency domain units in the frequency domain.

[0134] Alternatively, it can be understood that the first configuration information configures the reference subcarrier spacing in two dimensions: the reference subcarrier spacing in the time domain and the reference subcarrier spacing in the frequency domain.

[0135] With the first configuration information configured to specify the reference subcarrier spacing in both the time and frequency domains, it is advantageous to achieve fine-grained resource configuration in both the time and frequency domains.

[0136] 1.3 Temporal Scope of Application for the First Configuration Information

[0137] The temporal scope of the first configuration information can also be understood as the range in which the first configuration information applies in the temporal domain.

[0138] In some embodiments, the temporal domain scope of the first configuration information is less than or equal to the temporal domain scope corresponding to the first period.

[0139] Optionally, in the default mode, the time domain scope of the first configuration information is equal to the time domain scope corresponding to the first period. This is the simplest configuration method for configuring the time domain scope of the first configuration information. For example, as shown in Figure 6, the time domain scope of the first configuration information is time domain scope 3.

[0140] Optionally, to reduce the overhead of indicating the time-frequency two-dimensional transmission direction, the time-domain scope of the first configuration information is narrowed. The time-domain scope of the first configuration information is within the time-domain range corresponding to the first cycle, and is explicitly or implicitly indicated by higher-layer signaling.

[0141] For example, the temporal scope of the first configuration information can be directly indicated by higher-layer signaling. One implementation involves the higher-layer signaling displaying the range from the a-th time unit to the b-th time unit (from early to late) within the first period as the temporal scope of the first configuration information, where a is a positive integer and b is an integer greater than a. If the value of a is not explicitly indicated, the temporal scope of the first configuration information is the range from the first time unit (or the earliest time unit) to the b-th time unit within the first period. If the value of b is not explicitly indicated, the temporal scope of the first configuration information is the range from the a-th time unit to the last time unit (or the latest time unit) within the first period. Another implementation involves the higher-layer signaling displaying the start time unit and the number of time units indicating the temporal scope of the first configuration information. For example, the temporal scope of the first configuration information can be explicitly indicated to begin from the a-th time unit within the first cycle and last for 8 time units (including the a-th time unit and the 7 time units following the a-th time unit; or, excluding the a-th time unit, the 8 time units following the a-th time unit). Another implementation involves higher-layer signaling displaying the end time unit and the number of time units indicating the temporal scope of the first configuration information. For example, the temporal scope of the first configuration information can be explicitly indicated to end at the b-th time unit within the first cycle and last for 8 time units (including the b-th time unit and the 7 time units preceding the b-th time unit; or, excluding the b-th time unit, the 8 time units preceding the b-th time unit).

[0142] For example, higher-layer signaling implicitly indicates the time-domain scope of the first configuration information by indicating time units within the first cycle other than those indicated by the higher-layer signaling. That is, the range corresponding to the time units within the first cycle other than those indicated by the higher-layer signaling is the time-domain scope of the first configuration information. For instance, if the higher-layer signaling indicates that the first A time units within the first cycle are all uplink / downlink time units and the last B time units are all uplink / downlink time units, then the range corresponding to the intermediate time units within the first cycle other than the first A time units and the last B time units is the time-domain scope of the first configuration information.

[0143] In some embodiments, the temporal scope of the first configuration information is greater than or equal to a first range, where the first range is equal to the temporal range corresponding to one or more resource blocks. For example, if the first configuration information is used to configure the transmission direction of a resource block, then the temporal scope of the first configuration information is at least greater than the temporal range corresponding to one resource block. If the first configuration information is used to configure the transmission direction of multiple resource blocks, then the temporal scope of the first configuration information is at least greater than the temporal range corresponding to multiple resource blocks. For example, as shown in FIG6, the temporal scope of the first configuration information is greater than or equal to temporal scope 1, such as temporal scope 2.

[0144] 1.4 Frequency domain scope of the first configuration information

[0145] The frequency domain scope of the first configuration information can also be understood as the range in which the first configuration information operates in the frequency domain.

[0146] In some embodiments, the frequency domain range of the first configuration information is less than or equal to a preset frequency domain range, and the preset frequency domain range is equal to a carrier or a carrier group or a serving cell or a serving cell group or a BWP or a BWP group or a subband or a subband group.

[0147] Optionally, in the default mode, the frequency domain scope of the first configuration information is equal to the preset frequency domain range. This is the simplest configuration method for configuring the frequency domain scope of the first configuration information.

[0148] Optionally, to reduce the overhead of indicating the time-frequency two-dimensional transmission direction, the frequency domain scope of the first configuration information is narrowed. The frequency domain scope of the first configuration information is within a preset frequency domain range, and is explicitly or implicitly indicated by higher-layer signaling.

[0149] For example, the frequency domain scope of the first configuration information can be directly indicated by higher-layer signaling. One implementation involves the higher-layer signaling displaying the range from the c-th frequency unit to the d-th frequency unit (from low to high) within a preset frequency domain range as the frequency domain scope of the first configuration information, where c is a positive integer and d is an integer greater than c. If the value of c is not explicitly indicated, the frequency domain scope of the first configuration information is the range from the first frequency unit (or the lowest frequency unit) to the d-th frequency unit within the preset frequency domain range. If the value of d is not explicitly indicated, the frequency domain scope of the first configuration information is the range from the c-th frequency unit to the last frequency unit (or the highest frequency unit) within the preset frequency domain range. Another implementation involves the higher-layer signaling displaying the starting frequency unit and the number of frequency units indicating the frequency domain scope of the first configuration information. For example, the time-domain scope of the first configuration information can be explicitly indicated to start from the c-th frequency unit within a preset frequency domain range and last for 8 frequency units (including the c-th frequency unit and the 7 frequency units above the c-th frequency unit; or, excluding the c-th frequency unit, the 8 frequency units above the c-th time unit). Another implementation involves higher-layer signaling displaying the ending frequency unit and the number of frequency units indicating the frequency-domain scope of the first configuration information. For example, the frequency-domain scope of the first configuration information can be explicitly indicated to end at the d-th frequency unit within a preset frequency domain range and last for 8 frequency units (including the d-th frequency unit and the 7 frequency units below the d-th frequency unit; or, excluding the d-th frequency unit, the 8 frequency units below the d-th frequency unit).

[0150] For example, higher-layer signaling implicitly indicates the frequency domain scope of the first configuration information by specifying frequency domain units outside the frequency domain scope of the first configuration information within a preset frequency domain range. That is, the range corresponding to the other frequency domain units within the preset frequency domain range besides those specified by the higher-layer signaling is the frequency domain scope of the first configuration information. For instance, if the higher-layer signaling specifies that the lowest C frequency domain units within the preset frequency domain range are all uplink / downlink frequency domain units and the highest D frequency domain units are all uplink / downlink frequency domain units, then the range corresponding to the intermediate frequency domain units within the preset frequency domain range excluding the lowest C and highest D frequency domain units is the frequency domain scope of the first configuration information.

[0151] In some embodiments, the frequency domain scope of the first configuration information is greater than or equal to the second scope, where the second scope is equal to the frequency domain scope corresponding to one or more resource blocks. For example, if the first configuration information is used to configure the transmission direction of a resource block, then the frequency domain scope of the first configuration information is at least greater than the frequency domain scope corresponding to one resource block. If the first configuration information is used to configure the transmission direction of multiple resource blocks, then the frequency domain scope of the first configuration information is at least greater than the frequency domain scope corresponding to multiple resource blocks.

[0152] In some embodiments, when the first configuration information is cell-specific configuration information, the frequency domain scope of the first configuration information is a first frequency domain range; and / or, when the first configuration information is terminal device-specific configuration information, the frequency domain scope of the first configuration information is a second frequency domain range. The first frequency domain range is smaller than the second frequency domain range. Optionally, the first frequency domain range includes the minimum frequency domain bandwidth required for initial access, and the second frequency domain range includes the frequency domain bandwidth required for data transmission by the terminal device.

[0153] 1.5 Granularity of indication for the first configuration information

[0154] The granularity of the first configuration information includes: time-domain granularity and / or frequency-domain granularity. The time-domain granularity is used to indicate the number of time units corresponding to a resource block, and the frequency-domain granularity is used to indicate the number of frequency units corresponding to a resource block.

[0155] Optionally, the time-domain indicator granularity is used to indicate the X time units corresponding to a resource block. When the time-domain indicator granularity is not configured, or is not configured from the time-domain indicator granularity, or is the default, the time units corresponding to a resource block are x. X is a positive integer.

[0156] Optionally, the frequency domain indicator granularity is used to indicate the number of frequency domain cells corresponding to a resource block. When the frequency domain indicator granularity is not configured, or is not configured from the frequency domain indicator granularity, or is the default, the number of frequency domain cells corresponding to a resource block is y. The value of Y is a positive integer.

[0157] For example, as shown in Figure 7, the time domain indicator granularity is used to indicate that a resource block corresponds to 5 time units, and the frequency domain indicator granularity is used to indicate that a resource block corresponds to 4 frequency domain units.

[0158] With the granularity of the first configuration information being configurable, the network side can flexibly control the overhead of the first configuration information.

[0159] Regardless of the indication method, the number of bits required for the first configuration information can be obtained based on the time domain and / or frequency domain scope of the first configuration information, as well as the time domain indication granularity and / or frequency domain indication granularity of the first configuration information.

[0160] 1.6 Regarding the number of resource blocks

[0161] The number of resource blocks includes one or more of the following:

[0162] The first quantity refers to the number of resource blocks within the time domain scope of the first configuration information;

[0163] The second quantity is the number of resource blocks within the frequency domain scope of the first configuration information;

[0164] The third quantity refers to the number of resource blocks within the time domain and frequency domain of the first configuration information.

[0165] For example, as shown in Figure 8, the number of resource blocks within the time domain of the first configuration information is 4, or it can be understood as the time domain of the first configuration information including 4 resource blocks. The number of resource blocks within the frequency domain of the first configuration information is 2, or it can be understood as the frequency domain of the first configuration information including 2 resource blocks. The total number of resource blocks within both the time domain and frequency domain of the first configuration information is 4*2=8, or it can be understood as the time domain and frequency domain of the first configuration information including 8 resource blocks.

[0166] In some embodiments, the value of the third quantity is related to the values ​​of the first quantity and the second quantity. The third quantity is equal to the product of the first quantity and the second quantity. In one possible case, the first configuration information is used to configure one of the first quantity and the second quantity, while configuring a target value, which is determined based on the first quantity and the second quantity. For example, the target value includes the ratio of the first quantity to the second quantity, or the product of the first quantity and the second quantity.

[0167] With the number of resource blocks configurable, the network side can flexibly control the overhead of indicating the first configuration information.

[0168] 2. For resource blocks

[0169] In some embodiments, the time domain scope of the first configuration information includes a first number of resource blocks, which correspond to a fourth number of time units, and the fourth number is greater than or equal to the first number.

[0170] In some embodiments, the frequency domain scope of the first configuration information includes a second number of resource blocks, corresponding to a fifth number of frequency domain units. The fifth number is greater than or equal to the second number.

[0171] For example, as shown in Figure 9, in order to reduce the indication overhead of the first configuration information, in the frequency domain, the lowest part of the frequency domain resources are configured as all downlink resources, the highest part of the frequency domain resources are configured as all uplink resources, and in the middle frequency domain range, the first part of the time units are configured as all downlink resources, the last part of the time units are configured as all uplink resources, and the middle part is the scope of the first configuration information.

[0172] Within the scope of the first configuration information, the time domain is approximately uniformly divided into 4 first transmission resources, and the frequency domain is approximately uniformly divided into 3 first transmission resources, for a total of 4*3=12 resource blocks. Among them, 3 resource blocks are configured as all downlink resource blocks, 3 resource blocks are configured as all uplink resource blocks, 4 resource blocks are configured as duplex resource blocks, and 2 resource blocks are configured as flexible resource blocks.

[0173] The term "approximately uniform" is used because the fourth number of time units may not be evenly distributed among the resource blocks within the first number of time domain ranges, and / or the fifth number of frequency domain units may not be evenly distributed among the resource blocks within the second number of frequency domain ranges.

[0174] Optionally, the number of time units corresponding to each resource block in the first number of resource blocks is determined according to a first value, and / or the number of frequency domain units corresponding to each resource block in the second number of resource blocks is determined according to a second value. The first value is determined based on the ratio of the first number to the fourth number, and the second value is determined based on the ratio of the second number to the fifth number.

[0175] In some embodiments, each of the first M1 resource blocks in the first number of resource blocks includes K1 time units. M1 is equal to the remainder when the fourth quantity is the dividend and the first quantity is the divisor. K1 is equal to the floor value of the first value, and the first value is equal to the quotient when the fourth quantity is the dividend and the first quantity is the divisor. Each of the last M2 resource blocks in the first number of resource blocks corresponds to K2 time units, and the sum of M1 and M2 is the first quantity. K2 is equal to the floor value of the first value, and the first value is equal to the quotient when the fourth quantity is the dividend and the first quantity is the divisor. The sum of K1 and K2 is the fourth quantity.

[0176] In some embodiments, each of the first N1 resource blocks in the second number of resource blocks corresponds to L1 frequency domain units. Here, N1 is equal to the remainder when the fifth number is the dividend and the second number is the divisor. L1 is equal to the floor value of the second value, and the second value is equal to the quotient when the fifth number is the dividend and the second number is the divisor. Each of the last N2 resource blocks corresponds to L2 frequency domain units, and the sum of N1 and N2 is the second number. L2 is equal to the floor value of the second value, and the second value is equal to the quotient when the fifth number is the dividend and the second number is the divisor. The sum of L1 and L2 is the fifth number.

[0177] In some embodiments, the first configuration information indicates the transmission direction of each resource block using one or two of the following methods. For example:

[0178] Method 1: Using a bitmap for indication;

[0179] Method 2: Use start and / or length indicator values.

[0180] Regarding method one:

[0181] The first configuration information uses a bitmap to indicate the transmission direction of each resource block in one or more resource blocks. When the number of resource blocks corresponding to the first configuration information that require transmission direction configuration is small, indicating the transmission direction of each resource block based on the bitmap is beneficial for saving indication resources.

[0182] In some embodiments, the values ​​corresponding to each transmission direction are pre-configured by the network side or pre-defined by the protocol. For example, the protocol pre-defined the value as 001 for downlink, 010 for uplink, 011 for flexible transmission, 100 for duplex, 101 for reserved transmission, and 110 for guard band.

[0183] In some embodiments, when the frequency domain ranges of the resource blocks whose transmission directions need to be configured are the same, the first configuration information indicates the transmission direction of each resource block sequentially, either from early to late in the time domain or from late to early in the time domain. For example, assuming the time domains correspond to {resource block 1, resource block 2, resource block 3, resource block 4} from early to late, where all four resource blocks correspond to the same frequency domain range, the first configuration information can indicate the transmission direction of each resource block sequentially, either from early to late in the time domain or from late to early in the time domain. For instance, assuming the first configuration information is configured with "001001010101", then in the order from early to late in the time domain, the transmission direction of resource block 1 is downlink, resource block 2 is downlink, resource block 3 is uplink, and resource block 4 is reserved.

[0184] In some embodiments, when the time-domain scope of the resource blocks whose transmission directions need to be configured corresponding to the first configuration information is the same, the first configuration information indicates the transmission direction of each resource block sequentially according to the frequency domain from low to high or from high to low. For example, assuming the frequency domain from low to high corresponds to {resource block 1, resource block 2, resource block 3, resource block 4}, where all four resource blocks correspond to the same time-domain scope, the first configuration information can indicate the transmission direction of each resource block sequentially according to the frequency domain from low to high or from high to low. For instance, assuming the first configuration information is configured with "001001010101", then according to the frequency domain from low to high, the transmission direction of resource block 1 is downlink, resource block 2 is downlink, resource block 3 is uplink, and resource block 4 is reserved.

[0185] In some embodiments, when at least two resource blocks in the resource blocks corresponding to the first configuration information that require configured transmission directions have different time-domain ranges and at least two resource blocks have different frequency-domain ranges, the first configuration information can sequentially indicate the transmission direction of each resource block in one or more resource blocks in either the time-domain first or frequency-domain first order. For example, as shown in Figure 8, assuming the time domain corresponds to {resource block 1, resource block 2, resource block 3, resource block 4} and {resource block 5, resource block 6, resource block 7, resource block 8} from early to late, where the frequency-domain ranges corresponding to {resource block 1, resource block 2, resource block 3, resource block 4} are the same, the frequency-domain ranges corresponding to {resource block 5, resource block 6, resource block 7, resource block 8} are the same, and the frequency-domain ranges corresponding to {resource block 1, resource block 2, resource block 3, resource block 4} and {resource block 5, resource block 6, resource block 7, resource block 8} are different. The first configuration information can indicate the transmission direction of each resource block in one or more resource blocks in the order of time domain first and then frequency domain. For example, assuming the first configuration information is configured as "001001010101001001010101", then in the order of frequency domain from low to high, the transmission directions of resource block 1, 2, 3, 4, 5, 6, 7, and 8 are respectively: downlink, uplink, reserved.

[0186] Regarding method two:

[0187] The first configuration information uses start and / or length indication values ​​to indicate the time unit and / or frequency unit and / or transmission direction of each resource block. When the number of resource blocks corresponding to the first configuration information that require configuration of transmission direction is large, indicating the transmission direction of each resource block based on the bitmap will require a large amount of indication resources. In this case, the start and / or length indication values ​​can be used to indicate the transmission direction of each resource block separately.

[0188] In some embodiments, when the frequency domain range of the resource blocks corresponding to the first configuration information that need to be configured for transmission direction is the same, the first configuration information indicates the start time unit and / or the number of time units for each resource block by using start and / or length indication values.

[0189] In some embodiments, when the time domain scope of the resource blocks corresponding to the first configuration information that need to configure the transmission direction is the same, the first configuration information indicates the starting frequency domain unit and / or the number of frequency domain units of each resource block by using a start and / or length indication value.

[0190] In some embodiments, when at least two resource blocks in the resource blocks corresponding to the first configuration information that require configuration of transmission direction have different time domain ranges and at least two resource blocks have different frequency domain ranges, the first configuration information indicates the start time unit and / or the number of time units and the start frequency domain unit and / or the number of frequency domain units for each resource block by using start and / or length indication values.

[0191] In some embodiments, when adjacent first and second resource blocks in the frequency domain have different transmission directions, one of the first and second resource blocks includes a guard band. This approach can be understood as implicitly indicating the guard band, which helps reduce indication overhead. Alternatively, it can be understood as implicitly indicating that either the first or second resource block includes a guard band when adjacent first and second resource blocks in the frequency domain have different transmission directions. Optionally, when adjacent first and second resource blocks in the frequency domain have different transmission directions, the first resource block includes a guard band. Optionally, when adjacent first and second resource blocks in the frequency domain have different transmission directions, the second resource block includes a guard band.

[0192] In some embodiments, the transmission directions of the first resource block and the second resource block are different, including one or more of the following:

[0193] The transmission direction of the first resource block is downlink, and the transmission direction of the second resource block is uplink;

[0194] The transmission direction of the first resource block is uplink, and the transmission direction of the second resource block is downlink;

[0195] The transmission direction of the first resource block is downlink, and the transmission direction of the second resource block is full-duplex;

[0196] The transmission direction of the first resource block is full-duplex, and the transmission direction of the second resource block is downlink;

[0197] The transmission direction of the first resource block is uplink, and the transmission direction of the second resource block is full-duplex.

[0198] The transmission direction of the first resource block is full-duplex, and the transmission direction of the second resource block is uplink;

[0199] The transmission direction of the first resource block is downlink, and the transmission direction of the second resource block is flexible.

[0200] The transmission direction of the first resource block is flexible, and the transmission direction of the second resource block is downlink;

[0201] The transmission direction of the first resource block is uplink, and the transmission direction of the second resource block is flexible.

[0202] The transmission direction of the first resource block is flexible, and the transmission direction of the second resource block is uplink;

[0203] The transmission direction of the first resource block is full-duplex, and the transmission direction of the second resource block is flexible.

[0204] The transmission direction of the first resource block is flexible, and the transmission direction of the second resource block is full-duplex.

[0205] In some embodiments, a resource block comprising a guard band in the first resource block and the second resource block is determined based on one or more of the following methods:

[0206] A resource block is the one with the higher index value of the frequency domain cell between the first and second resource blocks;

[0207] A resource block is the one with the lower index value of the frequency domain cell in the first and second resource blocks;

[0208] A resource block is the one with the most frequency domain units between the first and second resource blocks;

[0209] A resource block is the one with fewer frequency domain units between the first and second resource blocks;

[0210] A resource block is the one of the first and second resource blocks that is transmitted in the downlink direction;

[0211] A resource block is the first resource block and the second resource block that is transmitted in the uplink direction;

[0212] A resource block is one of the first and second resource blocks that is transmitted in a full-duplex direction;

[0213] A resource block is the first resource block and the second resource block, and its transmission direction is flexible.

[0214] For example, as shown in Figures 10 and 11, it is assumed that resource block 1 and resource block 2 have different transmission directions in the frequency domain, and the index value of resource block 1 is higher than the index value of resource block 2. Optionally, as shown in Figure 10, resource block 1 includes a guard band, which is a segment in resource block 1 starting from the lowest frequency domain unit. Optionally, as shown in Figure 11, resource block 2 includes a guard band, which is a segment in resource block 2 starting from the highest frequency domain unit.

[0215] For example, as shown in Figures 10 and 11, it is assumed that resource block 1 and resource block 2 have different transmission directions in the frequency domain, and the number of frequency domain units in resource block 1 is greater than the number of frequency domain units in resource block 2. Optionally, as shown in Figure 10, resource block 1 includes a guard band, which is a segment in resource block 1 starting from the lowest frequency domain unit. Optionally, as shown in Figure 11, resource block 2 includes a guard band, which is a segment in resource block 2 starting from the highest frequency domain unit.

[0216] Including guard bands on resource blocks with a large number of frequency domain units helps to allocate sufficient resources for data transmission in each resource block. For example, if a guard band is included on a resource block with a small number of frequency domain units, there may not be enough resources for data transmission in that resource block; however, if a guard band is included on a resource block with a large number of frequency domain units, then even if some resources are used for guard bands, there will still be enough resources for data transmission.

[0217] In some embodiments, if the number of frequency domain units in the first resource block and the second resource block are equal, then the resource block including the guard band is the one with the higher index value of the frequency domain unit in the first resource block and the second resource block; or, it is the one with the lower index value of the frequency domain unit in the first resource block and the second resource block; or, it is the one with the downlink transmission direction in the first resource block and the second resource block; or, it is the one with the uplink transmission direction in the first resource block and the second resource block; or, it is the one with the full-duplex transmission direction in the first resource block and the second resource block; or, it is the one with the flexible transmission direction in the first resource block and the second resource block.

[0218] For example, as shown in Figures 10 and 11, assuming that resource block 1 and resource block 2 in the frequency domain have different transmission directions, with resource block 1 transmitting in the downlink direction and resource block 2 transmitting in the non-downlink direction, then resource block 1 includes a guard band, which is a segment in resource block 1 starting from the lowest frequency domain unit. By including a guard band in the resource block with the downlink transmission direction, it is easier to ensure compatibility with the initial access process, especially for Physical Random Access Channel (PRACH) transmissions.

[0219] In some embodiments, if the transmission directions of the first resource block and the second resource block are the same, then the resource block including the guard band is the one with the higher index value of the frequency domain unit in the first resource block and the second resource block; or, it is the one with the lower index value of the frequency domain unit in the first resource block and the second resource block; or, it is the one with more frequency domain units in the first resource block and the second resource block; or, it is the one with fewer frequency domain units in the first resource block and the second resource block.

[0220] It should be noted that any step performed by the terminal device can be implemented as an independent embodiment. Similarly, any step performed by the network device can be implemented as an independent embodiment. The steps performed by the terminal device and the steps performed by the network device can be combined to form a new combined embodiment. For example, as shown in FIG12, the method is jointly performed by the terminal device and the network device, and the method includes:

[0221] Step 11: The network device sends the first configuration information to the terminal device;

[0222] Optionally, the specific implementation method refers to step 320 above.

[0223] Step 12: The terminal device receives the first configuration information sent by the network device.

[0224] Optionally, the specific implementation method refers to step 220 above.

[0225] Figure 13 shows a structural block diagram of a terminal device provided in an exemplary embodiment of this application. The terminal device includes a receiving module 1010.

[0226] The receiving module 1010 is used to receive first configuration information, which is used to configure the transmission direction of one or more resource blocks.

[0227] In some embodiments, the first configuration information includes: cell-specific configuration information and / or terminal-specific configuration information. The cell-specific configuration information enables fixed resource configuration, is applicable to idle users, and allows for forward compatibility; the terminal-specific configuration information enables transmission direction indication based on the terminal's service characteristics and service ratio, achieving user-centric resource configuration.

[0228] Optionally, cell-specific configuration information is configured via broadcast information, such as MIB and / or SIB. Optionally, terminal-specific configuration information is configured via terminal-specific RRC signaling.

[0229] In some embodiments, each resource block in one or more resource blocks includes one or more time units in the time domain and one or more frequency units in the frequency domain. Alternatively, it can be understood that the "resource block" described in the embodiments of this application is a two-dimensional resource block including both time and frequency domain dimensions.

[0230] Optionally, each resource block includes one or more time units in the time domain and at least two frequency units in the frequency domain. Alternatively, each resource block includes at least two time units in the time domain and one or more frequency units in the frequency domain. In particular, if a resource block includes one time unit in the time domain and one frequency unit in the frequency domain, then the resource block constitutes one time-frequency unit.

[0231] In some embodiments, different resource blocks may include the same or different numbers of time units in the time domain. Different resource blocks may also include the same or different numbers of frequency units in the frequency domain. For example, as shown in FIG4, resource block 1 includes 3 time units in the time domain and 3 frequency units in the frequency domain. Resource block 2 includes 2 time units in the time domain and 3 frequency units in the frequency domain.

[0232] In some embodiments, a time unit includes one or more of the following: a symbol, a symbol group, a sub-slot, a slot, a subframe, and a frame.

[0233] In some embodiments, the frequency domain unit includes one or more of the following: RE, RE group, RB, RB group, subband, BWP, and carrier.

[0234] Optionally, a "resource block" can also be called a "transmission resource block" or a "time-frequency resource block". In this embodiment, only the term "resource block" is used as an example for illustration.

[0235] In some embodiments, the transmission direction of the resource block includes one or more of the following: downlink, uplink, flexible, full-duplex, reserved, and guard band.

[0236] Optionally, "the first configuration information is used to configure the transmission direction of one or more resource blocks" can also be understood as "the first configuration information is used to configure the resource type of one or more resource blocks". Further, the resource type includes one or more of the following: downlink resources, uplink resources, flexible resources, duplex resources, reserved resources, and guard band resources. Among these, flexible resources can better achieve the purpose of allocating resources according to dynamic changes in services; reserved resources can achieve a function similar to semi-static BWP handover and also achieve forward compatibility; duplex resources can perform both uplink and downlink transmission, making them true full-duplex resources with the highest resource utilization; guard band resources can be configured between resources in different transmission directions to reduce interference.

[0237] In some embodiments, the terminal device does not expect conflicts between cell-specific configuration information and terminal-device-specific configuration information. Such conflicts include situations where the cell-specific configuration information configures the transmission direction of one or more resource blocks as a first direction, while the terminal-device-specific configuration information configures the transmission direction of one or more resource blocks as a second direction, and the first and second directions are different. For example, the cell-specific configuration information configures the transmission direction of one or more resource blocks as uplink, while the terminal-device-specific configuration information configures the transmission direction of one or more resource blocks as downlink. Another example is that the cell-specific configuration information configures the transmission direction of one or more resource blocks as downlink, while the terminal-device-specific configuration information configures the transmission direction of one or more resource blocks as uplink.

[0238] In some embodiments, the terminal device further includes a determination module 1020.

[0239] The determination module 1020 is used to determine the transmission direction of a resource block or the terminal behavior on a resource block based on the indication of the terminal device-specific configuration information when there is a conflict between the cell-specific configuration information and the terminal device-specific configuration information. If the cell-specific configuration information configures the transmission direction of one or more resource blocks as a first direction, and the terminal device-specific configuration information configures the transmission direction of one or more resource blocks as a second direction, the module determines that the transmission direction of one or more resource blocks is the second direction, or the terminal device performs transmission according to the second direction in one or more resource blocks. For example, if the cell-specific configuration information configures the transmission direction of one or more resource blocks as uplink, and the terminal device-specific configuration information configures the transmission direction of one or more resource blocks as downlink, the module determines that the transmission direction of one or more resource blocks is downlink, or the terminal device performs downlink reception in one or more resource blocks and / or does not perform uplink transmission.

[0240] In some embodiments, since the "resource block" in this application is a two-dimensional resource block including both time and frequency domains, the "transmission direction of the resource block" is also a two-dimensional transmission direction including both time and frequency domains.

[0244] Figure 14 shows a structural block diagram of a network device provided in an exemplary embodiment of this application. The network device includes a transmitting module 1110.

[0245] The sending module 1110 is used to send first configuration information, which is used to configure the transmission direction of one or more resource blocks.

[0246] In some embodiments, the first configuration information includes: cell-specific configuration information and / or terminal-specific configuration information. The cell-specific configuration information enables fixed resource configuration, is applicable to idle users, and allows for forward compatibility; the terminal-specific configuration information enables transmission direction indication based on the terminal's service characteristics and service ratio, achieving user-centric resource configuration.
