It should be noted that this application embodiment only uses a base station in an NR system as an example for description and does not limit the specific type of base station.

[0052] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0053] Currently, mobile communication systems need to adapt to more diverse scenarios and service requirements. For example, key 5G scenarios include Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communication (URLLC), and Massive Machine-Type Communication (mMTC). These scenarios place demands on the system to achieve high reliability, low latency, high bandwidth, and wide coverage. For different carriers, base stations configure corresponding uplink-downlink configurations (TDD-UL-DL-Configuration), with each slot / symbol being uplink, downlink, or a flexible slot / symbol. On each carrier, the terminal only operates on its own active UL bandwidth part (BWP) or active DL BWP. In Rel-18, base station side subband full duplex (SBFD) operation was introduced. Within the SBFD slot, the base station can perform uplink and downlink transmissions simultaneously on different frequency domain resources. The uplink resource is the UL subband configured by the base station, which is located in the active DL BWP.

[0054] TDD Uplink / Downlink Configuration (TDD-UL-DL-Configuration):

[0055] In LTE, uplink and downlink configurations are based on time slots, or subframes. LTE TDD includes 7 configurations.

[0056] In NR, uplink and downlink configurations are symbol-level granularity, offering greater flexibility. The specific configuration process is as follows:

[0057] (1) First, configure the semi-static uplink and downlink configuration of the cell:

[0058] The higher layers provide the Common TDD Uplink / Downlink Configuration (TDD-UL-DL), which includes the reference subcarrier spacing u (reference SCS configuration) and pattern 1. Pattern 1 further includes:

[0059] Slot configuration period, P ms

[0060] Dslots (number of slots with only downlink symbols)

[0061] Dsym (number of downlink symbols)

[0062] Uplink slots (Uslots)

[0063] Usym (number of uplink symbols)

[0064] In the configuration cycle, the first Dslots are downlink time slots, followed by Dsym downlink symbols, then Usym uplink symbols, and finally Uslots uplink time slots. The remaining slots are flexible symbols X. That is, each TDD UL-DL configuration contains at least one DL symbol / time slot, and / or one UL symbol / time slot, and / or one flexible symbol / time slot.

[0065] (2) Then configure the terminal-specific uplink and downlink configurations:

[0066] If, based on the configuration in (1), a higher-level parameter-specific TDD uplink / downlink configuration (TDD-UL-DL-ConfigDedicated) is further provided, this parameter can configure the flexible symbol of TDD-UL-DL-ConfigurationCommon. That is to say, the uplink / downlink symbol configured in (1) cannot be changed, but the flexible symbol can be overwritten by TDD-UL-DL-ConfigurationDedicated.

[0067] This parameter provides a series of time slot configurations. For each time slot configuration, it provides a slot index and symbol configuration. For the slot specified by the slot index, where:

[0068] If symbols = allDownlink, then all symbols in the slot are downlink.

[0069] If symbols = allUplink, all symbols in the slot are uplink;

[0070] If symbols = explicit, the parameter nrofDownlinkSymbols provides the number of downlink first.

[0071] Optionally, if symbols are configured as explicit, then the parameter nrofDownlinkSymbols provides the number of downlink symbols, and nrofUplinkSymbols provides the number of uplink symbols. Optionally, downlink symbols are placed first, and uplink symbols are placed last. If the parameter nrofDownlinkSymbols is not provided, there are no downlink symbols; if nrofUplinkSymbols is not provided, there are no uplink symbols. If there are any remaining symbols after configuration, they are still flexible symbols. The reference subcarrier spacing (reference SCS configuration) in (2) is the same as in (1).

[0072] (3) Uplink and downlink configuration of Dynamic Downlink Control Information (DCI):

[0073] The uplink and downlink configuration implemented by dynamic DCI is achieved through DCI format 2-0, or directly through uplink and downlink data scheduling of DCI formats 0-0, 0-1, 1-0, and 1-1. DCI format 2-0 is specifically used as a Slot Format Indicator (SFI). The SFI mainly implements the periodic frame structure configuration based on the slot formats supported by a single slot. That is, starting from the receipt of DCI format 2-0, it continuously monitors the Physical Downlink Control Channel (PDCCH) for a monitoring period of slots, and these slots are configured according to the indications of the SFI in this DCI. The maximum number of formats supported by a single slot is 256, of which 56 formats have been standardized.

[0074] BWP:

[0075] In NR, the network configures one or more BWPs for the UE and / or performs data transmission. A BWP is a continuous segment of resources in the frequency domain. The UE dynamically changes bandwidth by activating different BWPs, as shown in Figure 2a. At the first moment, the UE's traffic is high, so the UE activates a large bandwidth (BWP1); at the second moment, the UE's traffic is low, so the UE activates a small bandwidth (BWP2) to meet basic communication needs; at the third moment, the system detects a large area of ​​frequency-selective fading within the bandwidth of BWP1, or that resources within the frequency range of BWP2 are scarce, and thus instructs the UE to activate a new bandwidth (BWP3).

[0076] Each BWP can correspond to different configuration parameters, including subcarrier spacing, BWP location and bandwidth, and cyclic prefix (CP).

[0077] SBFD:

[0078] As shown in Figure 2b, after the base station configures UL BWP, DL BWP, and TDD uplink / downlink configuration for the UE, the base station can configure the time-domain and frequency-domain resources for SBFD operation. The frequency-domain resources must include at least the UL subband; the DL subband is used for uplink and downlink transmissions. For example, if SBFD operation is configured in the 3rd, 4th, and 5th semi-static DL slots, the UL subband is active within these slots. The base station can simultaneously receive uplink transmissions on the UL subband and perform downlink transmissions on the DL subband within the SBFD symbol / time slot, thus achieving base station-side SBFD. The terminal can only receive on the DL subband or transmit on the UL subband within the SBFD symbol / time slot. Furthermore, if the terminal can simultaneously receive on the DL subband or transmit on the UL subband within the SBFD symbol / time slot, then terminal-side SBFD can be achieved.

[0079] The resource configuration method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0080] Please refer to Figure 3, which is a flowchart of a resource configuration method provided in an embodiment of this application. This method can be executed by a terminal, and as shown in Figure 3, it includes the following steps:

[0081] Step 301: The terminal receives the first information and the second information from the network-side device;

[0082] The first information includes at least one of first configuration information and second configuration information. The first configuration information is used to configure at least one frequency domain unit, and the second configuration information is used to configure at least one frequency domain unit group. The second information is used to determine at least one transmission type, which is the transmission type of a time domain unit. The transmission type is associated with at least one frequency domain unit or at least one frequency domain unit group, and the frequency domain unit group includes at least one frequency domain unit.

[0083] In this embodiment, the aforementioned frequency domain unit may include, but is not limited to, a band, a BWP, a subband, a carrier, or a continuous segment of frequency domain resources. For example, the aforementioned continuous segment of frequency domain resources may include at least twenty consecutive Physical Resource Blocks (PRBs).

[0084] For example, the first configuration information mentioned above may include configuration information of at least one frequency domain unit. The configuration information of each frequency domain unit may include the frequency domain information of that frequency domain unit, wherein the frequency domain information of that frequency domain unit may include, but is not limited to, at least one of the following: frequency domain start position, bandwidth, frequency domain end position, center carrier frequency, subcarrier spacing, cyclic prefix (CP), etc.

[0085] In some optional embodiments, the configuration information of each frequency domain unit may further include at least one of the following: the duplex mode, transmission direction, and band number corresponding to the frequency domain unit. For example, the duplex mode may include TDD, FDD, or SBFD. The transmission direction may include uplink or downlink. Optionally, the band number corresponding to the frequency domain unit can be used to determine the duplex mode of the frequency domain unit. For example, the correspondence between band numbers and duplex modes can be predefined by the protocol or configured on the network side, and thus the duplex mode corresponding to the frequency domain unit can be determined based on the band number corresponding to the frequency domain unit.

[0086] In some alternative embodiments, the network-side device can configure or indicate at least one of the following information: duplex mode, transmission direction, and band number, corresponding to at least one frequency domain unit, using signaling different from the signaling carrying the first configuration information. That is, at least one of the following information—duplex mode, transmission direction, and band number—corresponding to at least one frequency domain unit is configured or indicated using different signaling than the first configuration information. For example, at least one of the following information—duplex mode, transmission direction, and band number—corresponding to at least one frequency domain unit can be configured or indicated using Radio Resource Control (RRC), Media Access Control Control Element (MAC CE), or Downlink Control Information (DCI).

[0087] The aforementioned at least one frequency domain unit may include, but is not limited to, at least one of an uplink frequency domain unit, a downlink frequency domain unit, and a guard band. The uplink frequency domain unit can be used for uplink transmission, the downlink frequency domain unit can be used for downlink transmission, and the guard band cannot be used for transmission.

[0088] The following examples illustrate the configuration of frequency domain units:

[0089] When a base station configures frequency domain units for a terminal, the first configuration information sent to the terminal may include configuration information for at least one frequency domain unit. The configuration information for each frequency domain unit may include at least one of the following: frequency domain start position, bandwidth, end position, center carrier frequency, subcarrier spacing, and CP (Concurrent Carrier Component). Furthermore, the base station may also configure the duplex mode or band number corresponding to that frequency domain unit for the terminal. Considering that TDD bands do not distinguish between uplink and downlink spectrum, the transmission direction of that frequency domain unit can be further indicated.

[0090] One optional configuration method is to include the duplex mode of each frequency domain unit in its configuration information. For example, the configuration information for frequency domain unit 0 is {frequency domain information 0, TDD, DL}, and the configuration information for frequency domain unit 1 is {frequency domain information 1, TDD, UL}. Based on the configuration information of frequency domain unit 0 and frequency domain unit 1, it can be known that frequency domain unit 0 and frequency domain unit 1 are the downlink and uplink frequency domain units for TDD, respectively. It is understandable that a similar configuration method can be used for FDD frequency domain resources. Taking the use of band number to indicate the duplex mode as an example, the configuration information for frequency domain unit 2 is {frequency domain information 2, n7, DL}, and the configuration information for frequency domain unit 3 is {frequency domain information 3, n7, UL}. Considering that FDD is a symmetrical spectrum, the location of uplink and downlink resources can be clearly known. Therefore, no additional transmission direction configuration is needed; the uplink or downlink frequency domain unit can be determined based on the frequency domain information of the frequency domain unit. For example, the configuration information of frequency domain unit 2 is {frequency domain information 2, n7}, and the configuration information of frequency domain unit 3 is {frequency domain information 3, n7}. Based on frequency domain information 2, frequency domain information 3, and n7, it can be determined that frequency domain unit 2 and frequency domain unit 3 are uplink frequency domain units or downlink frequency domain units.

[0091] Furthermore, if further configuration of the guard band is required, the guard band can be indicated by not configuring the transmission direction. For example, if the configuration information of frequency domain unit 4 is {frequency domain information 4, n40}, then frequency domain unit 4 is a guard band within TDD band n40.

[0092] Furthermore, if there is a need to configure a guard band within the FDD band, the example above of not configuring the transmission direction for FDD is no longer applicable. In this case, the configuration of all uplink or downlink frequency domain units in the FDD band must include the transmission direction, while the guard band does not. For example, the configuration information of frequency domain unit 5 is {frequency domain information 5, FDD}, where frequency domain unit 5 is the guard band within the FDD band.

[0093] Another optional configuration method is to configure the duplex mode of the frequency domain units through separate signaling. The configuration information of the aforementioned frequency domain units may no longer include duplex mode or band number information. For example, if the base station configures the duplex mode of the frequency domain units as TDD, then the configuration information of frequency domain unit 0 is {frequency domain information 0, DL}, the configuration information of frequency domain unit 1 is {frequency domain information 1, UL}, and the configuration information of frequency domain unit 4 (as a guard band) is {frequency domain information 4}. Alternatively, if the base station configures the duplex mode of the frequency domain units as FDD, then the configuration information of frequency domain unit 2 is {frequency domain information 2, DL}, the configuration information of frequency domain unit 3 is {frequency domain information 3, UL}, and the configuration information of frequency domain unit 5 (as a guard band) is {frequency domain information 5}. Similarly, for FDD, if there is no requirement to configure a guard band, the transmission direction configured for the uplink or downlink frequency domain units can be omitted, and only the frequency domain information needs to be configured. For example, the configuration information for frequency domain unit 2 is {frequency domain information 2}, and the configuration information for frequency domain unit 3 is {frequency domain information 3}.

[0094] Another optional configuration method is to explicitly configure the transmission direction, that is, to directly define the transmission direction of the frequency domain unit, rather than obtaining it through configuration information. The duplex mode can be configured through separate signaling or together with the frequency domain information. For example, the configuration information for downlink frequency domain unit 0 is {frequency domain information 0, TDD}, the configuration information for downlink frequency domain unit 2 is {frequency domain information 2, FDD}, the configuration information for uplink frequency domain unit 1 is {frequency domain information 1, TDD}, the configuration information for uplink frequency domain unit 3 is {frequency domain information 3, FDD}, the configuration information for guard band frequency domain unit 4 is {frequency domain information 4, n40}, and the configuration information for guard band frequency domain unit 5 is {frequency domain information 5, FDD}. Alternatively, for TDD transmission, the configuration information of downlink frequency domain unit 0 is {frequency domain information 0}, the configuration information of uplink frequency domain unit 1 is {frequency domain information 1}, and the configuration information of frequency domain unit 4, which serves as a guard band, is {frequency domain information 4}; for FDD transmission, the configuration information of downlink frequency domain unit 2 is {frequency domain information 2}, the configuration information of uplink frequency domain unit 3 is {frequency domain information 3}, and the configuration information of frequency domain unit 5, which serves as a guard band, is {frequency domain information 5}.

[0095] The second configuration information described above is used to configure at least one frequency domain unit group, which may also be referred to as a frequency domain unit set or frequency domain unit combination. Each frequency domain unit group includes at least one frequency domain unit.

[0096] For example, the second configuration information mentioned above may include configuration information of at least one frequency domain unit group. The configuration information of each frequency domain unit group may include configuration information of all frequency domain units in the frequency domain unit group. The configuration information of each frequency domain unit may include at least one of the following: frequency domain information, duplex mode, transmission direction, band number, etc. For example, at least one of the following: frequency domain start position, bandwidth, end position, center carrier frequency, subcarrier spacing, CP, etc.; or, the configuration information of each frequency domain unit group may include the identifier or index of all frequency domain units in the frequency domain unit group, etc. For example, the configuration information of frequency domain unit group 1 is {frequency domain unit 1, frequency domain unit 3}, and the configuration information of frequency domain unit group 2 is {frequency domain unit 2}.

[0097] In some optional embodiments, the frequency domain units of at least one frequency domain unit group configured by the second configuration information are all frequency domain units configured by the first configuration information.

[0098] The aforementioned second information is used to determine at least one transmission type, which represents the transmission type of a time-domain unit. It should be noted that the transmission types involved in the embodiments of this application can all represent the transmission type of a time-domain unit; to avoid repetition, they will not be elaborated upon below.

[0099] For example, the at least one transmission type mentioned above may include, but is not limited to, at least one of uplink transmission type, downlink transmission type, hybrid transmission type, and flexible transmission type. The time domain unit mentioned above may be at least one time slot, at least one symbol, at least one subframe, at least one frame, at least one millisecond, or at least one second, etc. The time domain unit of the at least one transmission type mentioned above may be at least one time domain unit configured on the network side, or it may be at least one default time domain unit, etc. It should be noted that the above transmission type may also be referred to as time domain unit type. For ease of description, the above uplink transmission type may be abbreviated as UL, the above downlink transmission type may be abbreviated as DL, the above hybrid transmission type may be abbreviated as M, and the above flexible transmission type may be abbreviated as flexible or F.

[0100] Each of the above-mentioned at least one transmission type is associated with at least one frequency domain unit or at least one group of frequency domain units, and thus the transmission corresponding to that transmission type can be performed based on the time domain unit of each transmission type and the at least one frequency domain unit or at least one group of frequency domain units associated with each transmission type.

[0101] It should be noted that the first configuration information and the second configuration information mentioned above can be configured using the same signaling or using different signaling. Furthermore, the second information can be configured using the same signaling as at least one of the first and second configuration information, or it can be configured using different signaling than both the first and second configuration information; this embodiment does not impose any limitations on this.

[0102] For example, after step 301, the terminal can determine at least one of uplink transmission resources and downlink transmission resources based on the first information and the second information; and transmit an uplink signal on the uplink transmission resources, and / or receive a downlink signal on the downlink transmission resources. The uplink transmission resources may include Physical Uplink Control Channel (PUCCH) resources, Physical Uplink Sharing Channel (PUSCH) resources, Sounding Reference Signal (SRS) resources, etc., and the downlink transmission resources include Physical Downlink Control Channel (PDCCH) resources, Physical Downlink Shared Channel (PDSCH) resources, Channel State Information Reference Signal (CSI-RS) resources, etc. Uplink signals can include signals on PUCCH resources, signals on PUSCH resources, SRS, etc., while downlink signals can include signals on PDCCH resources, signals on PDSCH resources, CSI-RS, positioning reference signal (PRS), etc.

[0103] In this embodiment, the terminal receives first information from a network-side device. This first information includes at least one of first configuration information and second configuration information. The first configuration information is used to configure at least one frequency domain unit, and the second configuration information is used to configure at least one frequency domain unit group. The frequency domain unit group includes at least one frequency domain unit, thus enabling the configuration of frequency domain resources when the communication system supports multiple duplex modes. Furthermore, the terminal receives second information from a second network-side device. This second information is used to determine at least one transmission type, which is the transmission type of a time domain unit. The transmission type is associated with at least one frequency domain unit or at least one frequency domain unit group. This enables the configuration of time domain resources when the communication system supports multiple duplex modes. Moreover, since at least one transmission type can be determined through the second information, the terminal or network side can perform at least one of uplink and downlink transmissions based on at least one transmission type, allowing the terminal or network side to flexibly support different duplex modes. Compared to related technologies where time and frequency resources are configured separately for each duplex mode, the embodiments of this application can achieve unified configuration of multiple different duplex modes through the first information and the second information. This not only improves the flexibility of resource configuration, but also reduces the occurrence of redundant configuration signaling and configuration parameters, thus saving resource configuration overhead.

[0104] Optionally, the at least one transmission type includes at least one of uplink transmission type, downlink transmission type, hybrid transmission type, and flexible transmission type.

[0105] Among them, the time domain unit of the above-mentioned uplink transmission type can be used for uplink transmission, the time domain unit of the above-mentioned downlink transmission type can be used for downlink transmission, the time domain unit of the above-mentioned hybrid transmission type can be used for both uplink and downlink transmission, and the time domain unit of the above-mentioned flexible transmission type can be used for either uplink or downlink transmission.

[0106] Optionally, the frequency domain resources associated with the uplink transmission type include uplink frequency domain units; and / or,

[0107] The frequency domain resources associated with the downlink transmission type include downlink frequency domain units; and / or,

[0108] The frequency domain resources associated with the hybrid transmission type include uplink frequency domain units and downlink frequency domain units; and / or,

[0109] The frequency domain resources associated with the flexible transport type include at least one of the default uplink frequency domain unit and the default downlink frequency domain unit.

[0110] The frequency domain resource is a frequency domain cell or a group of frequency domain cells, or the frequency domain resource is a frequency domain cell in a group of frequency domain cells that is in an active or effective state.

[0111] For example, when the second information includes the first indication information or the second indication information, the frequency domain resource can be a frequency domain unit or a group of frequency domain units; when the second information includes the third indication information, the frequency domain resource can be a frequency domain unit in the group of frequency domain units that is in an active or effective state.

[0112] The following examples illustrate this embodiment:

[0113] Network-side equipment can configure at least one frequency domain unit for a terminal. This frequency domain unit can be an uplink frequency domain unit, a downlink frequency domain unit, or a guard band. A time domain unit for a transmission type, or a transmission type, can correspond to one or more frequency domain units. For example, a downlink time domain unit can correspond to one or more downlink frequency domain units, an uplink time domain unit can correspond to one or more uplink frequency domain units, a hybrid time domain unit can correspond to one or more downlink frequency domain units, and one or more uplink frequency domain units. Optionally, the time domain unit for the aforementioned transmission type can also correspond to one or more guard bands.

[0114] For example, downlink transmission type DL1 corresponds to downlink frequency domain unit 1, downlink transmission type DL2 corresponds to downlink frequency domain unit 2, and downlink transmission type DL3 corresponds to {downlink frequency domain unit 1, downlink frequency domain unit 2}; uplink transmission type UL1 corresponds to uplink frequency domain unit 1, uplink transmission type UL2 corresponds to uplink frequency domain unit 2, and uplink transmission type UL3 corresponds to {uplink frequency domain unit 1, uplink frequency domain unit 2}; hybrid transmission type M1 corresponds to {downlink frequency domain unit 3, guard band 1, uplink frequency domain unit 3}, and hybrid transmission type M2 corresponds to {downlink frequency domain unit 4, uplink frequency domain unit 4}. And so on. Figure 4a is a schematic diagram of the correspondence between transmission types and frequency domain units provided in the embodiments of this application.

[0115] For the flexible transmission type, there can be a default uplink frequency domain unit and a default downlink frequency domain unit. For example, the flexible transmission type corresponds to {downlink frequency domain unit 1, uplink frequency domain unit 1}. However, if there is a transmission, only one frequency domain unit is active at any given time, depending on whether the transmission configured or scheduled within the flexible usage unit is uplink or downlink. If it is an uplink transmission, the flexible time domain unit corresponds to the default uplink frequency domain unit; if it is a downlink transmission, the flexible time domain unit corresponds to the default downlink frequency domain unit. If the flexible time domain unit is rewritten to downlink transmission type DL1, it corresponds to downlink frequency domain unit 1; if it is rewritten to hybrid transmission type M1, it corresponds to {downlink frequency domain unit 3, guard band 1, uplink frequency domain unit 3}.

[0116] For hybrid transmission types, assuming the duplex mode of downlink frequency domain unit 4 and uplink frequency domain unit 4 is FDD, then FDD transmission can be performed in hybrid time domain unit M2. If the duplex mode of downlink frequency domain unit 3 and uplink frequency domain unit 3 is TDD, then SBFD transmission can be performed in hybrid time domain unit M1, including base station-side SBFD transmission and / or UE-side SBFD transmission.

[0117] Optionally, the frequency domain resources associated with the target transmission type also include guard bands, and the target transmission type includes at least one of the following: uplink transmission type, downlink transmission type, and hybrid transmission type;

[0118] And / or,

[0119] The frequency domain resources associated with the flexible transmission type also include the default guard band.

[0120] Optionally, the transmission type includes at least one subtype, and different subtypes correspond to different frequency domain units or frequency domain unit groups.

[0121] Taking the example of a downlink transmission type including at least one subtype, the downlink transmission type may include downlink transmission type DL1, downlink transmission type DL2 and downlink transmission type DL3, etc., where downlink transmission type DL1 corresponds to downlink frequency domain unit 1, downlink transmission type DL2 corresponds to downlink frequency domain unit 2, downlink transmission type DL3 corresponds to {downlink frequency domain unit 1, downlink frequency domain unit 2}, and so on.

[0122] Optionally, the second information includes first indication information, which is used to indicate the at least one transmission type.

[0123] For example, at least one transmission type can be explicitly indicated by the first indication information. For instance, different values ​​can be indicated by the first indication information to represent different transmission types, as shown in Figure 4b. This indication method is not only more flexible, but also makes it easier for the terminal to quickly learn the transmission type of the time domain unit.

[0124] Optionally, the first indication information includes at least one first index, which is used to indicate a transmission type.

[0125] The first index mentioned above can be any index used to indicate a transmission type.

[0126] For example, each first index may be used to indicate only one transmission type. In this case, the time domain unit or effective time of the transmission type indicated by each first index may be a default time domain unit or effective time, or it may be a time domain unit or effective time predefined by the protocol, or it may be an independently indicated or configured time domain unit or effective time, etc.; or, each first index may indicate a transmission type and the time domain unit or effective time of that transmission type, etc.

[0127] In some optional embodiments, the number of bits of the first index can be determined based on the number of time-domain unit types configured by the network-side device for the terminal, or based on the number of time-domain unit types (i.e., transmission types) supported by the terminal, or can be agreed upon by the protocol.

[0128] Optionally, the first index is further used to indicate the first parameter corresponding to the transmission type indicated by the first index;

[0129] or,

[0130] The method further includes: the terminal receiving third information from the network-side device, the third information including a first parameter corresponding to the transmission type indicated by each of the first indices;

[0131] The first parameter includes at least one of the following: the number of time-domain units, the carrier spacing, the granularity of the time-domain units, the size of the time-domain units, and the effective time.

[0132] For example, the carrier spacing may include the subcarrier spacing. The size of the time-domain unit may be determined by the subcarrier spacing and the granularity of the time domain (e.g., slot, symbol). The effective time may be determined based on the number and size of the time-domain units.

[0133] In some implementations, each first index is used to indicate a transmission type and a first parameter corresponding to that transmission type. This allows the indicated transmission type and the first parameter corresponding to that transmission type to be easily known based on the first index, which helps to save configuration overhead.

[0134] For example, the first parameters indicated by different first indices can be the same, for example, each first index indicates T1 time domain units 1; or the first parameters indicated by different first indices can be different, for example, first index 1 indicates T2 time domain units 2, first index 2 indicates T3 time domain units 3, and so on.

[0135] The following examples illustrate this implementation method:

[0136] The base station configures a transmission type for the terminal, each corresponding to an index. This index indicates the transmission type, as well as the size and number of time-domain units. The base station assigns a set of indices to the terminal to indicate the transmission type over a period of time. For example, index0 (000) corresponds to transmission type DL1, SCS = 15kHz or μ = 0, 2 time slots. index1 (001) corresponds to transmission type UL1, SCS = 15kHz or μ = 0, 21 symbols. index2 (010) corresponds to transmission type flexible, SCS = 15kHz or μ = 0, 7 symbols. index3 (011) corresponds to transmission type M1, SCS = 15kHz or μ = 0, 7 symbols. index4 (100) corresponds to transmission type UL2, SCS = 15kHz or μ = 0, 1 time slot. All frequency domain units are in TDD duplex mode.

[0137] When the base station indicates {000 011 011 011 001}, the corresponding transmission type configuration can be as shown in Figure 4c. Among them, DL... f 1 represents the bandwidth of downlink frequency domain unit 1, corresponding to transmission type DL1; UL f 1 represents the bandwidth of uplink frequency domain unit 1, corresponding to transmission type UL1; DL f 2 is the bandwidth of downlink frequency domain unit 3, UL f 2 represents the bandwidth of uplink frequency domain unit 4, corresponding to transmission type M1. This set of indices indicates a transmission type with a subcarrier spacing of 15 kHz and a period of 5 slots (2 slots + 3*7 symbols + 21 symbols). The first two slots of this period are downlink time domain units, the last half slot is an uplink time domain unit, and the middle slot is a mixed time domain unit, which can perform SBFD transmission.

[0138] When the base station indicates {000 010 010 011 011 100}, the corresponding transmission type configuration is shown in Figure 4d. This index indicates a transmission type with a subcarrier spacing of 15kHz and a period of 5 slots (2 slots + 2*7 symbols + 2*7 symbols + 1 slot). The first two slots of this period are downlink time domain units, the next slot is a flexible slot, the next slot or 14 symbols is an SBFD slot / symbol, and the last slot is an uplink time domain unit, with a larger bandwidth corresponding to the uplink frequency domain unit.

[0139] In other embodiments, each first index can be used to indicate a transmission type, and the first parameter corresponding to the transmission type indicated by each first index can be configured independently. For example, the signaling carrying the first index can also carry the first parameter corresponding to the transmission type indicated by each first index; or, the first parameter corresponding to the transmission type indicated by each first index can be indicated or configured by signaling different from the signaling carrying the first index. For example, the first parameter corresponding to the transmission type indicated by the first index can be configured or indicated by RRC, MAC CE or DCI, which is beneficial to improving the flexibility of the configuration of the first parameter corresponding to the transmission type.

[0140] For example, index0 (000) corresponds to transmission type DL1, index1 (001) corresponds to transmission type UL1, index2 (010) corresponds to transmission type flexible, index3 (011) corresponds to transmission type M1, and index4 (100) corresponds to transmission type UL2. All frequency domain units are in TDD duplex mode. Furthermore, each index is configured with a corresponding effective time, determined by the time domain unit size and the number of time domain units. The time domain unit size can be determined by the subcarrier spacing and the time domain granularity (e.g., slot, symbol). For example, the effective time of the transmission type indicated by the above indices can be configured using a table in the format shown in Table 1, or through separate signaling such as RRC, MAC CE, or DCI.

[0141] Table 1

[0142] In some optional embodiments, the sum of the lengths of all time-domain units of the transmission type indicated by the at least one first index is the indication period of the transmission type; or, the sum of all effective times of the transmission type indicated by the at least one first index is the indication period of the transmission type.

[0143] Optionally, the first indication information includes at least one first table index, which is used to indicate at least one transmission type; wherein, the first table index is a row index or column index of the first table, and each row or column of the first table includes at least one transmission type.

[0144] In this embodiment, the aforementioned first table index is either a row index or a column index of a first table, and each row or column of the first table includes at least one transmission type. The period corresponding to the transmission type indicated by each row or column of the first table may be different. For example, each first table index may be used only to indicate at least one transmission type. In this case, the time domain unit or effective time of each transmission type indicated by each first table index can be a default time domain unit or a default effective time, or it can be a time domain unit or effective time predefined by the protocol, or it can be an independently indicated or configured time domain unit or effective time, etc.; or, each first table index can indicate at least one transmission type and the time domain unit or effective time of each transmission type, etc. For example, as shown in Table 2, each row includes at least one transmission type, and the effective time of the transmission types in Table 2 can be configured by RRC. If not configured, the effective time is a default time.

[0145] Table 2

[0146] In this embodiment, at least one transmission type can be indicated by a first table index, which helps to further save configuration overhead.

[0147] Optionally, the first table index is further used to indicate a first parameter corresponding to each of the at least one transmission type indicated by the first table index, and each row or column of the first table further includes the first parameter corresponding to the at least one transmission type.

[0148] or,

[0149] The method further includes: the terminal receiving fourth information from the network-side device, the fourth information including a first parameter corresponding to each transmission type indicated by each of the first table indexes;

[0150] The first parameter includes at least one of the following: the number of time-domain units, the carrier spacing, the granularity of the time-domain units, the size of the time-domain units, and the effective time.

[0151] For example, the carrier spacing may include the subcarrier spacing. The size of the time-domain unit may be determined by the subcarrier spacing and the granularity of the time domain (e.g., slot, symbol). The effective time may be determined based on the number and size of the time-domain units.

[0152] In some implementations, each first table index is used to indicate at least one transmission type and a first parameter corresponding to each transmission type. This allows for easy identification of the indicated at least one transmission type and the time domain unit or effective time of each transmission type based on the first table index, which helps to save configuration overhead.

[0153] In other embodiments, each first table index can be used to indicate at least one transmission type, and the first parameter corresponding to each transmission type indicated by each first table index can be configured independently. For example, the signaling carrying the first table index can also carry the first parameter corresponding to each transmission type indicated by each first table index; or, the first parameter corresponding to each transmission type indicated by each first table index can be indicated or configured by signaling different from the signaling carrying the first table index, for example, by configuring or indicating the first parameter corresponding to each transmission type indicated by the first table index through RRC, MAC CE or DCI, which is beneficial to improving the flexibility of configuring the first parameter corresponding to the transmission type.

[0154] The following explanation uses the effective time of the configured transmission type as an example:

[0155] The effective time of the transmission type indicated by the index in the first table above can be configured by column, by row, or by cell in the first table. For configuring the effective time of the transmission type by column, for example, with a subcarrier spacing of 15KHz, the effective time of columns 0-2 in Table 2 is 1 slot, the effective time of columns 3-6 is 7 symbols, and the effective time of columns 7-9 is 2 slots. Then, the transmission type indicated by index 1 in row 2 includes DL1 with 2 slots, flexible with 2 slots (1 slot + 2*7 symbols), M1 with 1 slot (2*7 symbols), UL2 with 6 slots, and a period of 11 slots with a subcarrier spacing of 15KHz (2+2+1+6). The transmission types indicated by row index 5 in Table 2 include DL1 (1 slot), flexible (1 slot), M1 (1 slot), UL2 (2 slots, 4*7 symbols), and slots with a period of 5 subcarriers spaced at 15kHz. For configuring the effective time of transmission types by row, for example, the effective time for each transmission type in each row of indexes 0-3 and index 5 of Table 2 is 1 slot; the effective time for each transmission type in each row of indexes 4 and 6 of Table 2 is 2 slots, and so on. For configuring the effective time of transmission types by cell, for example, as shown in Table 3, the subcarrier spacing of each row, and the granularity and number of time-domain units corresponding to each transmission type in each row can be indicated.

[0156] Table 3

[0157] Optionally, the transmission type and effective time can be configured in the same table, as shown in Tables 4-1 to 4-3. It should be noted that, for simplicity, the example configurations only include a limited number of transmission types.

[0158] Table 4-1

[0159] Table 4-2

[0160] Table 4-3

[0161] In some optional embodiments, the first parameter corresponding to all transmission types included in each column or each row of the first table may be the same, or the first parameter corresponding to each transmission type included in the first table may be different.

[0162] In some optional embodiments, the sum of the valid times corresponding to all transmission types indicated by each first table index is the period of the transmission type indicated by that first table index.

[0163] In some optional embodiments, the indication period of the transmission type is the sum of the effective times corresponding to all transmission types indicated by the at least one first table index, or the indication period of the transmission type is the sum of the periods of the transmission types indicated by the at least one first table index.

[0164] Optionally, the second information includes second indication information, which is used to indicate at least one nominal transmission type and one frequency domain unit group associated with at least one frequency domain unit group for each nominal transmission type;

[0165] The at least one transmission type is determined based on the at least one nominal transmission type and one frequency domain unit group associated with each nominal transmission type.

[0166] For example, the above-mentioned at least one nominal transmission type may include at least one of uplink nominal transmission type, downlink nominal transmission type, mixed nominal transmission type and flexible nominal transmission type, and each nominal transmission type may be indicated by an index, for example, DL, UL, mixed and flexible correspond to indices 0, 1, 2 and 3 respectively.

[0167] Furthermore, each nominal transmission type can be associated with at least one frequency domain unit combination. For example, the downlink nominal transmission type corresponds to {frequency domain unit combination 1 {DL frequency domain unit 1}, frequency domain unit combination 2 {DL frequency domain unit 2}, and frequency domain unit combination 3 {DL frequency domain unit 1, DL frequency domain unit 2}}; the uplink nominal transmission type corresponds to {frequency domain unit combination 1 {DL frequency domain unit 1}, frequency domain unit combination 2 {DL frequency domain unit 2}, and frequency domain unit combination 3 {DL frequency domain unit 1, DL frequency domain unit 2}}; the hybrid nominal transmission type corresponds to {frequency domain unit combination 1 {downlink frequency domain unit 3, guard band 1, uplink frequency domain unit 3}, frequency domain unit combination 2 {downlink frequency domain unit 4, uplink frequency domain unit 4}}, and so on. Different frequency domain unit combinations can correspond to different subtypes. For example, if the downlink nominal transmission type corresponds to frequency domain unit combination 1, then the transmission type is downlink transmission type DL1; if the downlink nominal transmission type corresponds to frequency domain unit combination 2, then the transmission type is downlink transmission type DL2, and so on.

[0168] For example, the aforementioned second indication information may include a second index and a third index, wherein the second index may be used to indicate a nominal transmission type and the third index may be used to indicate a frequency domain unit combination. For instance, if all frequency domain unit combinations associated with each nominal transmission type are numbered starting from 0, then {0,0} indicates downlink transmission type DL1, {0,2} indicates downlink transmission type DL3, {2,0} indicates hybrid transmission type M1, {2,1} indicates hybrid transmission type M2, and so on.

[0169] Optionally, the second information includes at least one sub-configuration information, which is used to configure the transmission type for a period; wherein the transmission type in the period includes at most three transmission types, and the order of the time domain units of the three transmission types is predefined by the protocol or configured by the network-side device.

[0170] In this embodiment, a sub-configuration information is used to configure the transmission type for one cycle, that is, a sub-configuration information is used to configure the transmission type of a time-domain unit for one cycle. Each cycle includes at most three transmission types, and the three transmission types included in different cycles can be exactly the same or not exactly the same. For example, the transmission types in cycle 1 may include at most downlink, uplink, and hybrid transmission types, while the transmission types in cycle 2 may include at most downlink, uplink, and flexible transmission types. Furthermore, the order of the time-domain units of the three transmission types included in a cycle is predefined by the protocol or configured by the network-side device. For example, if the transmission types in a cycle include at most downlink, uplink, and hybrid transmission types, the transmission types in that cycle can be predefined by the protocol or configured by the network-side device to be arranged sequentially in the order of downlink, hybrid, and uplink.

[0171] For example, the sub-configuration information may include an index of one of the three transmission types in a period, in which case each transmission type in the period indicated by the sub-configuration information is the transmission type indicated by the index; or, the sub-configuration information may include indices of at least two of the three transmission types in a period and the number of time-domain units for each of the at least two transmission types; or, the sub-configuration information may include the number of time-domain units for each of the three transmission types in a period, and so on.

[0172] Optionally, the sub-configuration information includes the number of time-domain units for at least two of the three transmission types.

[0173] For example, when the sub-configuration information only includes the number of time-domain units for two of the three transmission types, the two transmission types can be the default two transmission types or the two transmission types agreed upon by the protocol. For instance, if the transmission types in one cycle include at most downlink transmission type, uplink transmission type, and hybrid transmission type, then the two transmission types can be agreed upon by the protocol as downlink transmission type and uplink transmission type, or as downlink transmission type and hybrid transmission type, or as uplink transmission type and hybrid transmission type. When the sub-configuration information includes the number of time-domain units for the three transmission types, the number of time-domain units for the three transmission types can be indicated according to the order of the time-domain units for the three transmission types.

[0174] It is understood that when the sub-configuration information includes the number of time-domain units for two of the three transmission types, the transmission type of the remaining time-domain units in the period indicated by the sub-configuration information is a transmission type other than the two transmission types mentioned above among the three transmission types. Specifically, the remaining time-domain units are the time-domain units in the period indicated by the sub-configuration information that are other than the two transmission types mentioned above.

[0175] In some optional embodiments, the sub-configuration information may further include an index of each of the at least two transport types.

[0176] For example, the sub-configuration information may include the transmission type index and the number of time domain units. For instance, if the indices of the three transmission types in a cycle are 0, 1, and 2 respectively, then if the sub-configuration information includes {(0,3), (2,1)}, it means that the number of time domain units for the transmission type with index 0 is 3, the number of time domain units for the transmission type with index 2 is 1, and the number of remaining time domain units in the cycle is the number of time domain units for the transmission type with index 1.

[0177] In some alternative embodiments, the indication period for the transmission type is the sum of all periods indicated by the at least one sub-configuration information.

[0178] Optionally, the second information includes third indication information, which is used to indicate the state of a frequency domain unit within at least one frequency domain unit group. The state of the frequency domain unit includes an active state or a deactivated state, or the state of the frequency domain unit includes an active state or a deactivated state.

[0179] For example, the third indication information is used to indicate the state of each frequency domain unit within at least one frequency domain unit group; or, the third indication information is used to indicate the state of some frequency domain units within at least one frequency domain unit group.

[0180] It is understood that the at least one transmission type can be determined based on the state of the frequency domain units within the frequency domain unit group associated with the at least one transmission type, i.e., the time domain configuration can be determined, for example, as shown in Figure 4e. For example, a frequency domain unit group includes an uplink frequency domain unit 1, a guard band 1, and a downlink frequency domain unit 1. If the third indication information indicates that the uplink frequency domain unit 1 is in an active state, and both the guard band 1 and the downlink frequency domain unit 1 are in an inactive state, then the transmission type associated with this frequency domain unit group is an uplink transmission type. If the third indication information indicates that the uplink frequency domain unit 1 and the guard band 1 are in an inactive state, and both the downlink frequency domain unit 1 are in an active state, then the transmission type associated with this frequency domain unit group is a downlink transmission type. If the third indication information indicates that the uplink frequency domain unit 1, the guard band 1, and the downlink frequency domain unit 1 are all in an active state, then the transmission type associated with this frequency domain unit group is a mixed transmission type.

[0181] It should be noted that the aforementioned third indication information indicates the state of the frequency domain unit within the frequency domain unit group associated with at least one time domain unit, and can also be referred to as the aforementioned third indication information indicating the time domain configuration associated with the frequency domain unit group.

[0182] In this embodiment, at least one transmission type is implicitly indicated by indicating the state of the frequency domain units within the frequency domain unit group associated with at least one time domain unit, which helps to save the overhead of transmission type indication.

[0183] Optionally, the third indication information includes at least one set of bits, which is used to indicate the state of a frequency domain cell within a frequency domain cell group.

[0184] For example, the set of bits can be used to indicate the state of each frequency domain unit within a frequency domain unit group, or the set of bits can be used to indicate the state of some frequency domain units within a frequency domain unit group. Optionally, if the frequency domain unit group includes a guard band, the state of the guard band may not be indicated; instead, the activation of the guard band can be determined by whether both uplink and downlink frequency domain units are activated simultaneously. For example, if both uplink and downlink frequency domain units in the frequency domain unit group are active, the guard band is also active; otherwise, the guard band is deactivated.

[0185] For example, the number of bits in each group can be determined based on the number of frequency domain units in the frequency domain unit group, or based on the maximum number of frequency domain units in the frequency domain unit group configured by the network side for the terminal, or it can be agreed upon by the protocol.

[0186] For example, each set of bits may be used only to indicate the state of a frequency domain unit within a frequency domain unit group. In this case, the time domain unit or effective time corresponding to the state of the frequency domain unit in the frequency domain unit group indicated by each set of bits may be a default time domain unit or a default effective time, or it may be a time domain unit or effective time predefined by the protocol, or it may be an independently indicated or configured time domain unit or effective time, etc.; or, each set of bits may indicate the state of a frequency domain unit within a frequency domain unit group and the corresponding time domain unit or effective time, etc.

[0187] Optionally, the set of bits is further used to indicate the first parameter corresponding to the state of the frequency domain unit of the frequency domain unit group indicated by the set of bits;

[0188] or,

[0189] The method further includes: the terminal receiving fifth information from the network-side device, the fifth information being used to indicate the first parameter corresponding to the state of the frequency domain unit of each frequency domain unit group indicated by the at least one set of bits;

[0190] The first parameter includes at least one of the following: the number of time-domain units, the carrier spacing, the granularity of the time-domain units, the size of the time-domain units, and the effective time.

[0191] For example, the carrier spacing may include the subcarrier spacing. The size of the time-domain unit may be determined by the subcarrier spacing and the granularity of the time domain (e.g., slot, symbol). The effective time may be determined based on the number and size of the time-domain units.

[0192] In some implementations, each set of bits is used to indicate the state of a frequency domain unit within a frequency domain unit group and the corresponding first parameter. This allows the state of the indicated frequency domain unit and the corresponding first parameter to be easily known based on each set of bits, which helps to save configuration overhead.

[0193] In other implementations, each set of bits is used to indicate the state of a frequency domain unit within a frequency domain unit group, and the first parameter corresponding to the state of the frequency domain unit indicated by each set of bits is configured independently. For example, the signaling carrying at least one set of bits can also carry the first parameter corresponding to the state of the frequency domain unit indicated by each set of bits; or, the first parameter corresponding to the state of the frequency domain unit indicated by each set of bits can be indicated or configured by signaling different from the signaling carrying at least one set of bits, which is beneficial to improving the flexibility of configuring the first parameter corresponding to the state of the frequency domain unit indicated by each set of bits.

[0194] The following examples illustrate this embodiment:

[0195] A set of bits can be used to indicate the state of a frequency domain cell within a frequency domain cell group. For example, 1 indicates activation / enable, and 0 indicates deactivation / inactivation. This set of bits can also correspond to the size and number of frequency domain cells. Therefore, a set of bits can indicate the state of a frequency domain cell group over a period of time. Assume a frequency domain cell group contains {uplink frequency domain cell 1, guard band 1, downlink frequency domain cell 1}. Each set of bits contains three bits, used to indicate the three frequency domain cells within the group. For example, 001 indicates that the downlink frequency domain unit is active, corresponding to the downlink transmission type, and SCS = 15kHz or μ = 0, with 2 slots; 000 indicates that all frequency domain units are inactive, corresponding to the flexible transmission type, and SCS = 15kHz or μ = 0, with 1 slot; 111 indicates that all frequency domain units are active, corresponding to the hybrid transmission type, and SCS = 15kHz or μ = 0, with 1 slot; 100 indicates that the uplink frequency domain unit is active, corresponding to the uplink transmission type, and SCS = 15kHz or μ = 0, with 1 slot. All frequency domain units are in TDD duplex mode. Therefore, the time-domain configuration indicated by {001 001 000 111 100} can be as shown in Figure 4f, containing 2 downlink slots, 1 flexible slot, 1 hybrid slot, and 1 uplink slot, with an indication period of 5 slots spaced at 15kHz subcarrier intervals. In the example of Figure 4f, if the uplink frequency domain unit, downlink frequency domain unit and guard band overlap, the uplink and downlink frequency domain units in the overlapping part are invalid when the guard band is effective or activated.

[0196] For example, 001 indicates that the downlink frequency domain unit is active, 000 indicates that all frequency domain units are inactive, 111 indicates that all frequency domain units are active, and 100 indicates that the uplink frequency domain unit is active. All frequency domain units are in TDD duplex mode. Configure the effective time information for these indices, including subcarrier spacing, time domain granularity, and number, as shown in Table 5. Other independent signaling configuration methods are not detailed here; the above effective time information can be configured using separate signaling. Therefore, the time domain configuration indicated by {001 001 000 111 100} includes 2 downlink slots, 1 flexible slot, 1 mixed slot, and 1 uplink slot, with an indication period of 5 slots with 15kHz subcarrier spacing. Another method is to have the same effective time for each group of bits, in which case only one effective time needs to be indicated. For example, if the effective time of each group of bits is 2 slots of 30KHz subcarrier spacing, then the time domain configuration indicated by {001 001 000 111 100} contains 4 downlink slots, 2 flexible slots, 2 mixed slots, and 2 uplink slots, and the indication period is 10 slots of 30KHz subcarrier spacing.

[0197] Table 5

[0198] In some optional embodiments, the size and number of time-domain units indicated by different groups of bits can be the same or different. Each group of bits indicates T1 time-domain units 1, or the first group of bits indicates T2 time-domain units 2, the second group of bits indicates T3 time-domain units 3, and so on. T1, T2, and T3 are all positive numbers.

[0199] In some optional embodiments, the effective time of the state of the frequency domain units in different groups of frequency domain units indicated by different sets of bits can be the same or different. For example, the effective time of the state of the frequency domain units in each group of frequency domain units indicated by each set of bits is T1 time domain units 1; or the effective time of the state of the frequency domain units in the first group of frequency domain units indicated by the first set of bits is T2 time domain units 2, the effective time of the state of the frequency domain units in the second group of frequency domain units indicated by the second set of bits is T3 time domain units 3, and so on. T1, T2, and T3 are all positive numbers.

[0200] In some optional embodiments, the sum of the lengths of all time-domain units corresponding to the state of the frequency-domain unit group indicated by the at least one set of bits is the indication period of the state of the frequency-domain unit within the frequency-domain unit group; or, the sum of the effective times of the state of the frequency-domain unit group indicated by the at least one set of bits is the indication period of the state of the frequency-domain unit within the frequency-domain unit group.

[0201] Optionally, the bits in the group of bits are mapped to the frequency domain units of the frequency domain unit group according to a preset rule.

[0202] In this embodiment, the bits in each group of bits are mapped to the frequency domain units of the frequency domain unit group they indicate according to a preset rule, so that the terminal can read the state of each frequency domain unit according to the mapping rule.

[0203] For example, uplink frequency domain units are indicated starting from the most significant bit (MSB), and downlink frequency domain units are indicated starting from the least significant bit (LSB), or vice versa, with extra bits set to zero or ignored by the terminal; if there are multiple uplink frequency domain units or multiple downlink frequency domain units, they are indicated sequentially according to the order in the frequency domain unit group configuration; or, the status of the frequency domain units is indicated sequentially starting from the MSB or LSB according to the order of the frequency domain unit group, with extra bits set to zero or ignored by the terminal.

[0204] It should be noted that the above set of bits can also be referred to as a bit group.

[0205] The following examples illustrate this embodiment:

[0206] If the number of bits in each group exceeds a threshold, then it is necessary to limit how many uplink frequency domain units this group of bits can indicate, or how many downlink frequency domain units it can indicate. The remaining bits are for guard bands. This threshold can be the minimum number of frequency domain units configured in the frequency domain unit combination for the terminal, or it can be a protocol agreement or predefined by the protocol.

[0207] For example, if each group of bits has 5 bits, the minimum number of frequency domain units in the terminal's frequency domain unit group is 3, and the number of uplink frequency domain units in each frequency domain unit group does not exceed 2, and the number of downlink frequency domain units does not exceed 2, then for the frequency domain unit group {uplink frequency domain unit 1, guard band 1, downlink frequency domain unit 1}, indication state 10101 indicates that all three frequency domain units in this frequency domain unit group are effective; for the frequency domain unit group {uplink frequency domain unit 1, guard band 1, downlink frequency domain unit 1, downlink frequency domain unit 2}, indication state 10110 indicates that uplink frequency domain unit 1, guard band 1, and downlink frequency domain unit 1 are effective, corresponding to hybrid time domain unit type M3, and indication state 10101 indicates that uplink frequency domain unit 1, guard band 1, and downlink frequency domain unit 2 are effective, corresponding to hybrid time domain unit type M4.

[0208] For example, the correspondence between the frequency domain units of the frequency domain unit group and the bits of the bit group may include at least one of the following:

[0209] The uplink frequency domain unit is indicated starting from the MSB, with a maximum of X bits;

[0210] Downlink frequency domain units are indicated starting from LSB, with a maximum of Y bits;

[0211] The remaining bits indicate the guard band;

[0212] The protection band indicator is located immediately adjacent to the uplink frequency domain unit indicator;

[0213] The protection band indicator is located immediately adjacent to the downlink frequency domain unit indicator.

[0214] For example, the correspondence between the frequency domain units of the frequency domain unit group and the bits of the bit group can include at least one of the following, depending on the configuration of the frequency domain units:

[0215] Downlink frequency domain units are indicated starting from the MSB, with a maximum of X bits;

[0216] The uplink frequency domain unit is indicated starting from the LSB, with a maximum of Y bits;

[0217] The remaining bits indicate the guard band;

[0218] The protection band indicator is located immediately adjacent to the uplink frequency domain unit indicator;

[0219] The protection band indicator is located immediately adjacent to the downlink frequency domain unit indicator.

[0220] Where X and Y are positive integers greater than or equal to 1. In the example above, both X and Y are equal to 2.

[0221] Optionally, the third indication information includes at least one second table index, which is used to indicate the state of each frequency domain cell in at least one frequency domain cell group;

[0222] The second table index is either a row index or a column index of the second table, and each row or column of the second table includes the state of each frequency domain unit of at least one frequency domain unit group.

[0223] In this embodiment, the aforementioned second table index is a row index or column index of the second table, and each row or column of the second table includes the state of each frequency domain unit of at least one frequency domain unit group. For example, each second table index may be used solely to indicate the state of each frequency domain unit of at least one frequency domain unit group. In this case, the time domain unit or effective time corresponding to the state of the frequency domain unit of at least one frequency domain unit group indicated by each second table index may be a default time domain unit or default effective time, or it may be a time domain unit or effective time predefined by the protocol, or it may be an independently indicated or configured time domain unit or effective time, etc.; or, each second table index may indicate the state of each frequency domain unit of at least one frequency domain unit group and the corresponding time domain unit or effective time, etc.

[0224] In this embodiment, a second table index can indicate the state of the frequency domain units of at least one frequency domain unit group, which helps to further save configuration overhead.

[0225] Optionally, the second table index is further used to indicate the first parameter corresponding to the state of the frequency domain unit of the frequency domain unit group indicated by the second table index, and each row or column of the second table also includes the first parameter corresponding to the state of the frequency domain unit of at least one frequency domain unit group.

[0226] or,

[0227] The method further includes: the terminal receiving sixth information from the network-side device, the sixth information being used to indicate the first parameter corresponding to the state of the frequency domain unit of the frequency domain unit group indicated by the at least one second table index;

[0228] The first parameter includes at least one of the following: the number of time-domain units, the carrier spacing, the granularity of the time-domain units, the size of the time-domain units, and the effective time.

[0229] For example, the carrier spacing may include the subcarrier spacing. The size of the time-domain unit may be determined by the subcarrier spacing and the granularity of the time domain (e.g., slot, symbol). The effective time may be determined based on the number and size of the time-domain units.

[0230] In some implementations, each second table index is used to indicate the state of the frequency domain units of at least one frequency domain unit group and the corresponding first parameter. This allows for convenient access to the state of the frequency domain units of the indicated at least one frequency domain unit group and the time domain unit or effective time corresponding to the state of the frequency domain units of each frequency domain unit group, which helps to save configuration overhead.

[0231] In other embodiments, each second table index can be used to indicate the state of frequency domain units in at least one frequency domain unit group, and the first parameter corresponding to the state of the frequency domain unit in each frequency domain unit group indicated by each second table index is configured independently. For example, the signaling carrying the second table index can also carry the first parameter corresponding to the state of the frequency domain unit in each frequency domain unit group indicated by the second table index; or, the first parameter corresponding to the state of the frequency domain unit in each frequency domain unit group indicated by each second table index can be indicated or configured by signaling different from the signaling carrying the second table index. For example, the first parameter corresponding to the state of the frequency domain unit in each frequency domain unit group indicated by the second table index can be configured or indicated by RRC, MAC CE or DCI, which is beneficial to improving the flexibility of configuring the first parameter corresponding to the state of the frequency domain unit.

[0232] The following examples illustrate this embodiment:

[0233] This embodiment can indicate the time-domain configuration of frequency unit groups through the second table index. For example, as shown in Table 6-1, each row indicates the status of 5 frequency units (FUs). If the frequency unit group is {uplink frequency unit 1, guard band 1, downlink frequency unit 1}, corresponding to FU0, FU2, and FU4 in the table, then index 2 indicates that all three frequency units in this frequency unit group are active. If the frequency unit group is {uplink frequency unit 1, guard band 1, downlink frequency unit 1, downlink frequency unit 2}, then index 2 indicates that uplink frequency unit 1, guard band 1, and downlink frequency unit 2 in this frequency unit group are active. The second table can also indicate information related to the effective time, such as subcarrier spacing, time-domain granularity, and the number of time units. As shown in Table 6-1, index 1 corresponds to one slot with an effective time of 15kHz subcarrier spacing, and index 2 corresponds to 21 symbols with an effective time of 30kHz subcarrier spacing. For example, for the frequency domain unit combination {uplink frequency domain unit 1, guard band 1, downlink frequency domain unit 1}, {index3, index3, index1, index1, index4} indicates 2 downlink slots, 2 mixed slots, and 1 uplink slot, corresponding to a 15kHz subcarrier spacing.

[0234] For example, as shown in Table 6-2, each cell in each row indicates the state of the three frequency domain units in a frequency domain unit group, and different columns correspond to different time domain units or different times. If the frequency domain unit group is {uplink frequency domain unit 1, guard band 1, downlink frequency domain unit 1}, then index 0 indicates that the frequency domain unit group uses downlink frequency domain unit 1 in all time domain units, and the corresponding transmission type is downlink transmission type; index 4 indicates that the frequency domain unit group uses uplink frequency domain unit 1 in all time domain units, and the corresponding transmission type is uplink transmission type; index 1 indicates that the frequency domain unit group uses downlink frequency domain unit 1 in both time domain units 0 and 1, and the corresponding transmission type is downlink transmission type; in time domain unit 2, none of the frequency domain units are effective, and the corresponding transmission type is flexible transmission type; in time domain unit 3, all frequency domain units are effective, and the corresponding transmission type is hybrid transmission type; in time domain unit 4, uplink frequency domain unit 1 is effective, and the corresponding transmission type is uplink transmission type. That is, index 1 indicates two downlink transmission types, one flexible transmission type, one hybrid transmission type, and one uplink transmission type, and so on. It should be noted that the effective time of the frequency domain unit status of each frequency domain unit group in Table 6-2 can be configured by RRC. If not configured, the effective time will be a default time.

[0235] Table 6-1

[0236] Table 6-2

[0237] For example, the effective time of each time-domain configuration in the second table can be configured by RRC. If not configured, the effective time is a default time. The effective time of the time-domain configuration in the second table can be configured by column, by row, or by table cell. For example, for column configuration, with a subcarrier spacing of 15 kHz, the effective time of columns 0-2 in Table 6-2 is 1 slot, and the effective time of columns 3-4 is 21 symbols. Then, the time-domain configuration indicated by index 1 in Table 6-2 includes 2 downlink slots, 1 flexible slot, 1 half-mixed slot (21 symbols), 1 half uplink slot (21 symbols), and a period of 6 slots with a subcarrier spacing of 15 kHz (2+1+1.5+1.5).

[0238] Furthermore, the effective time can be configured row by row. For example, the effective time for each time-domain configuration (i.e., the state of the frequency-domain unit in the frequency-domain unit group) in each row of index 0-index 2 in Table 6-2 is one slot; the effective time for each time-domain configuration in each row of index 3 and index 4 is two slots, and so on. Optionally, the effective time can also be configured for each transmission type in the second table. For example, see Table 6-3, which indicates the subcarrier interval corresponding to each row index in Table 6-2 and the time-domain granularity and number of effective time-domain configurations in each row.

[0239] Table 6-3

[0240] Optionally, the status and activation time of the frequency domain elements in a frequency domain unit group can be configured together in a table, as shown in Table 4. It should be noted that, for simplicity, the example configuration only includes the status of the frequency domain elements in a limited number of frequency domain unit groups.

[0241] Table 6-4

[0242] Optionally, a cell in the second table includes the state of a frequency domain unit, or a cell in the second table includes the state of each frequency domain unit in a frequency domain unit group, or a cell in the second table includes the state of each frequency domain unit in a frequency domain unit group and a first parameter corresponding to the state of the frequency domain unit in the frequency domain unit group.

[0243] The first parameter includes at least one of the following: the number of time-domain units, the carrier spacing, the granularity of the time-domain units, the size of the time-domain units, and the effective time.

[0244] In this embodiment, a cell in the second table includes the state of a frequency domain unit, for example, as shown in Table 6-1, where each row of Table 6-1 indicates the state of each frequency domain unit in a frequency domain unit group; or, a cell in the second table includes the state of each frequency domain unit in a frequency domain unit group, for example, as shown in Table 6-2, where each row of Table 6-2 indicates the different states of each frequency domain unit in a frequency domain unit group at different times, with the specific time related to the first parameter corresponding to the state of each frequency domain unit in the frequency domain unit group; or, a cell in the second table includes the state of each frequency domain unit in a frequency domain unit group and the first parameter corresponding to the state of the frequency domain unit in that frequency domain unit group, for example, as shown in Table 6-4.

[0245] In some optional embodiments, the first parameter corresponding to the state of all frequency domain units in each column or row of the second table may be the same, or the first parameter corresponding to the state of each frequency domain unit in each frequency domain unit group included in the second table may be different.

[0246] In some optional embodiments, the sum of the effective times corresponding to the states of the frequency domain units of all frequency domain unit groups indicated by each second table index is the period of the transmission type indicated by that second table index.

[0247] In some optional embodiments, the indication period of the transmission type is the sum of the effective times corresponding to the states of the frequency domain units of all frequency domain unit groups indicated by the at least one second table index, or the indication period of the transmission type is the sum of the periods of the transmission types indicated by the at least one second table index.

[0248] Optionally, the frequency domain units within the frequency domain unit group are sorted according to at least one of the following: the position of the frequency domain units in the frequency domain, and the priority of the transmission direction of the frequency domain units in the frequency domain unit group.

[0249] For example, the aforementioned positions in the frequency domain include at least one of a start position and an end position in the frequency domain. For instance, the frequency domain cells can be ordered sequentially from high to low or from low to high according to their start or end positions.

[0250] For example, the frequency domain unit groups are configured as follows: Frequency domain unit group 1: {downlink frequency domain unit 1, guard band 1, uplink frequency domain unit 1}, frequency domain unit group 2: {downlink frequency domain unit 1, downlink frequency domain unit 2, guard band 2, uplink frequency domain unit 2}, frequency domain unit group 3: {downlink frequency domain unit 1, guard band 1, uplink frequency domain unit 2, uplink frequency domain unit 1}, etc. All frequency domain units within a frequency domain unit group can be sorted sequentially from high to low or from low to high according to their starting or ending positions. For example, for frequency domain unit group 2, if sorted according to the starting position, the starting position of downlink frequency domain unit 1 is higher than the starting position of downlink frequency domain unit 2, the starting position of downlink frequency domain unit 2 is higher than the starting position of guard band 2, and the starting position of guard band 2 is higher than the starting position of uplink frequency domain unit 2.

[0251] In some optional embodiments, the frequency domain units within a frequency domain unit group can be sorted first according to their positions in the frequency domain. If two frequency domain units have completely overlapping positions, then the two frequency domain units can be sorted according to the priority order of the transmission direction of the frequency domain units.

[0252] Optionally, the method further includes:

[0253] When the network-side device configures at least two frequency domain unit groups for the terminal, the terminal receives the first signaling from the network-side device;

[0254] The first signaling is used to indicate that one of the at least two frequency domain unit groups is in an active or effective state.

[0255] It should be noted that the activation or effectiveness of a frequency domain unit group means that the frequency domain unit group can be used to determine the transmission type, and does not mean that all frequency domain units in the frequency domain unit group are activated or effective.

[0256] For example, when the network-side device configures at least two frequency domain unit groups for the terminal, the index of the frequency domain unit group that needs to be activated or effective can be indicated by DCI signaling.

[0257] Optionally, if the network-side device does not configure a frequency domain unit group for the terminal, the frequency domain unit group associated with the at least one transmission type is the default frequency domain unit group.

[0258] The default frequency domain unit group includes the initial uplink bandwidth portion (BWP) and the initial downlink bandwidth portion (BWP), or the default frequency domain unit group includes at least one frequency domain unit configured by the first configuration information.

[0259] For example, the default frequency domain unit group mentioned above may include all frequency domain units configured in the first configuration information. For instance, if the base station configures downlink frequency domain unit 1 and uplink frequency domain unit 2 for the UE, but does not configure a frequency domain unit group, then the default frequency domain unit group for the UE includes downlink frequency domain unit 1 and uplink frequency domain unit 2.

[0260] Optionally, the method further includes:

[0261] The terminal receives the second signaling sent by the network-side device;

[0262] The terminal adjusts the transmission type according to the second signaling.

[0263] For example, the second signaling can be dynamic signaling or UE-specific semi-static signaling. For instance, the dynamic signaling can include a slot format indicator (SFI), which indicates the time-domain format of each symbol of the time-domain element.

[0264] For example, if at least one of the above transmission types includes a flexible transmission type, the flexible transmission type can be adjusted to a downlink transmission type by sending a second signaling instruction.

[0265] Optionally, the indication period for the transmission type is the sum of the effective times of all transmission types indicated by the second information.

[0266] For example, when configuring via tables, at least two table indexes can be configured to indicate at least two cycles of transmission type configuration to the terminal, with the total indication cycle being the sum of the individual cycles. For instance, referring to Table 4-1, if {index1, index2} is indicated, it includes two cycles. The first cycle is the indication cycle for the transmission type indicated by index1, containing 1.5 slots of DL1, 0.5 slots of flexible, and 1 slot of UL2; the other cycle is the indication cycle for the transmission type indicated by index2, containing 1 slot of DL2, 1 slot of flexible, and 3 slots of M1. The total indication cycle is eight 15kHz slots.

[0267] For example, referring to Table 6-4, if the indication is {index0, index1, index2}, it contains three periods. The first period is the time-domain configuration indicated by index0, which contains 5 downlink slots; the second period is the time-domain configuration period indicated by index1, which contains 2 downlink slots, 1 flexible slot, 1.5 mixed slots, and 1.5 uplink slots; the third period is the time-domain configuration period indicated by index2, which contains 2 downlink slots, 5 mixed slots, and 1 uplink slot. The total indication period is 19 (5+6+8) 15kHz slots.

[0268] Optionally, the method further includes at least one of the following:

[0269] When the first cycle is less than or equal to the second cycle, the terminal does not expect a conflict between the second information indicated by two adjacent first cycles;

[0270] If the first period is longer than the second period, the terminal uses the default second information to determine the transmission type of the first time domain unit, or the terminal performs periodic transmission within the first period based on the transmission type indicated by the second period;

[0271] Wherein, the first time domain unit is a time domain unit not configured by the second information sent based on the first period, the first period is the signaling transmission period of the network-side device indicating the second information, and the second period is the indication period of the transmission type.

[0272] Exemplarily, if the period for the base station to send the second information is X time domain units and the indication period of the transmission type is Y time domain units, then when X = Y, the indicated second information will not overlap; when X < Y, there will be an overlapping part of the indicated second information. Then, the terminal does not expect the second information indicated by the two consecutive indication periods to conflict. That is, if slot n is indicated as the downlink time domain unit type DL1 in period 1, then in period 2, slot n cannot be indicated as a type other than the downlink time domain unit type DL1; if slot n is indicated as the flexible time domain unit type flexible in period 1, then in period 2, slot n can be configured as any time domain unit type that can overwrite the flexible type; when X > Y, within each signaling transmission period, there will be some resources not indicated by the second information. Then, the default second information can be used to determine the transmission type of the time domain units not indicated. For example, pre-configured second information, or, the transmission type indicated by the received second information can be used periodically within X time domain units until a new second information is received. For example, X is 6, Y is 3, and the transmission types of the Y time domain units are downlink transmission, flexible transmission, and downlink transmission in sequence. Then, the transmission types of the X time domain units are: downlink transmission, flexible transmission, downlink transmission, and downlink transmission, flexible transmission, downlink transmission in sequence.

[0273] In some optional embodiments, the information indicated by the second information (e.g., transmission type) takes effect at least M time domain units after the terminal receives the second information, where M is an integer greater than or equal to 0.

[0274] It should be noted that the BWP and subband involved in the embodiments of the present application only represent a part of the frequency domain resources and are not limited to the BWP or subband in the related art. In addition, the frequency domain positions and bandwidths of the resources in all the above embodiments are only examples, and can actually be at any position, any bandwidth, etc. For example, as shown in Figure 4g. Optionally, all time-frequency resources can be configured periodically.

[0275] In summary, the embodiments of the present application provide a specific signaling configuration method for flexible time-frequency resources, and achieve unified configuration or indication of time-frequency resources in TDD, FDD, SBFD and other modes through different signaling configuration or indication methods.

[0276] Please refer to Figure 5. Figure 5 is a flowchart of a resource configuration method provided by the embodiments of the present application. This method can be executed by a network-side device. As shown in Figure 5, it includes the following steps:

[0277] Step 501, the network-side device sends the first information and the second information to the terminal;

[0278] The first information includes at least one of first configuration information and second configuration information. The first configuration information is used to configure at least one frequency domain unit, and the second configuration information is used to configure at least one frequency domain unit group. The second information is used to determine at least one transmission type, which is the transmission type of a time domain unit.
