The number of terminal devices 10 is generally multiple, and one or more terminal devices 10 may be distributed in each cell managed by an access network device 20. The terminal device may also be referred to as a terminal or UE for short, and those skilled in the art will understand its meaning.

[0039] The access network device 20 is a device deployed in the access network to provide wireless communication functions for the terminal device 10. The access network device 20 may include various forms of macro network devices, micro network devices, relay stations, APs (Access Points), etc. In systems using different wireless access technologies, the names of devices with access network device functions may be different. For example, in the 5G NR (New Radio) system, it is called gNodeB or gNB (Next Generation Node B). With the evolution of communication technology, the name "access network device" may change. For the convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as access network devices. In some embodiments, a communication relationship can be established between the terminal device 10 and the core network network element 30 through the access network device 20. For example, in an LTE (Long Term Evolution) system, the access network device 20 may be an Evolved Universal Terrestrial Radio Access Network (EUTRAN) or one or more eNodeBs in the EUTRAN. In a 5G NR system, the access network device 20 may be a Radio Access Network (RAN) or one or more gNBs in the RAN. In the embodiments of the present application, unless otherwise specified, the "network device" referred to refers to the access network device 20, such as a network device.

The cell can be a cell corresponding to the network device (for example, a network device). The cell can belong to a macro network device or a network device corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0044] Before introducing the technical solutions of this application, we first introduce and explain some of the relevant technical knowledge involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least part of the following contents.

[0045] 1. TDD (Time Division Duplexing) uplink and downlink configuration

[0046] For the TDD system, the uplink and downlink configuration is used to configure / indicate the transmission direction of each time domain symbol, including: downlink symbols, flexible symbols, and uplink symbols. Specific configuration signaling includes: TDD uplink and downlink common configuration (TDD-UL-DL-ConfigCommon), TDD uplink and downlink dedicated configuration (TDD-UL-DL-ConfigDedicated), and slot format indicator (SFI). Among them, TDD-UL-DL-ConfigCommon and TDD-UL-DL-ConfigDedicated are high-layer signaling. The former is configured for the cell and sent to all users in the cell through broadcast information, and the latter is sent independently to the required users through RRC signaling. A single pattern (pattern 1) or a dual pattern (pattern 1 and pattern 2) can be configured in tdd-UL-DL-ConfigurationCommon. In each pattern period, the network can configure the time slot structure in the pattern. Based on tdd-UL-DL-ConfigurationCommon, the terminal device can determine the time slot structure within a single pattern (pattern 1) and repeat it in the time domain with a period of P. When tdd-UL-DL-ConfigurationCommon configures dual patterns, namely pattern 1 (corresponding to a period of P) and pattern 2 (corresponding to a period of P2), pattern 1 and pattern 2 appear alternately in the time domain, and P+P2 must be divisible by 20ms. TDD-UL-DL-ConfigDedicated can indicate the flexible time slot / symbol configured by TDD-UL-DL-ConfigCommon as uplink, downlink, or flexible symbol.

[0047] SFI is the DCI (Downlink Control Information) (also known as group common DCI) of the user group: DCI format 2_0 indicates the transmission direction of each time slot / symbol of each carrier. SFI is a dynamic signaling that can indicate the semi-statically configured flexible time slot / symbol (if only TDD-UL-DL-ConfigCommon is received, it is the flexible time slot / symbol indicated by TDD-UL-DL-ConfigCommon; if TDD-UL-DL-ConfigCommon and TDD-UL-DL-ConfigDedicated are received, it is the flexible time slot / symbol indicated by the two together) as a determined transmission direction, uplink or downlink.

[0048] 2. SBFD (Subband non-overlapping full duplex)

[0049] To overcome the issues of weak uplink coverage, long uplink latency, and insufficient uplink capacity caused by limited uplink resource allocation in NR TDD, XDD technology has been introduced. This technology allows data to be sent and received simultaneously on different subbands within the same subframe / timeslot / symbol. This technology is primarily used on the network equipment side, while the terminal device side only supports sending or receiving data within a subframe / timeslot / symbol. As shown in Figure 2, the middle subband of a downlink or flexible subframe / timeslot / symbol is configured as an uplink subband.

[0050] The following conclusions are disclosed in the related art:

[0051] -SBFD operates within one TDD carrier

[0052] -SBFD solution is designed within a single uplink and downlink BWP (Bandwidth Part) pair with aligned center frequencies.

[0053] - Within a TDD carrier, there is at most one uplink subband on an SBFD symbol (the uplink subband can be located in the middle or on both sides of the TDD carrier)

[0054] -SBFD operation within a TDD carrier

[0055] -SBFD scheme within a single configured DL and UL BWP pair with aligned center frequencies, and

[0056] -Up to one UL subband for SBFD operation in an SBFD symbol (excluding legacy UL symbol) within a TDD carrier (up to one UL subband for SBFD operation in an SBFD symbol (excluding legacy UL symbol) within a TDD carrier).

[0057] For semi-static SBFD, to avoid frequent switching between SBFD and non-SBFD symbols, a maximum of two switching points are supported within one TDD UL / DL pattern period, namely, one switching point from non-SBFD symbols to SBFD symbols and one switching point from SBFD symbols to non-SBFD symbols.

[0058] At least for semi-static SBFD, in order to avoid frequent switching between SBFD and non-SBFD symbols, potential limitation on the maximum number of transition points between SBFD and non-SBFD symbols can be considered from SBFD subband configuration perspective. Maximum of two transition points including one transition point from non-SBFD symbols to SBFD symbols and one transition point from SBFD symbols to non-SBFD symbols within a TDD UL / DL pattern period can be considered as a starting point where the transition point can be aligned with slot boundary or within a slot.

[0059] (Agreement) The usage of 'switching point' in previous conclusions / agreements are revised to 'transition point'

[0060] A guard period between SBFD and non-SBFD symbols may or may not be required at gNB and / or UE side depending on gNB / UE implementation and / or SBFD operation.

[0061] In addition, the relevant technology also stipulates that if the SBFD subband is used for uplink transmission, the SBFD subbands can only be configured on the downlink symbols or flexible symbols indicated by TDD-UL-DL-ConfigCommon, and uplink transmission can only be limited to the UL subband, and downlink reception can only be limited to the DL subband:

[0062] Transmission and reception behaviours on SBFD subbands configured in DL and / or flexible symbol indicated by TDD-UL-DL-ConfigCommon

[0063] UL transmissions within UL subband only

[0064] DL receptions within DL subband(s)only,except for CLI measurement by the UE outside of the DL subbands

[0065] According to the above-mentioned provision that SBFD subbands for uplink transmission can only be configured on downlink symbols or flexible symbols indicated by TDD-UL-DL-ConfigCommon, if for a flexible symbol configured by TDD-UL-DL-ConfigCommon, the terminal device further receives TDD-UL-DL-ConfigDedicated and / or DCI format 2_0 to further indicate it as a downlink symbol or an uplink symbol. In particular, when it is indicated as an uplink symbol, there are two ways to understand the bandwidth of the uplink transmission within the symbol:

[0066] Uplink transmission can only occur within the UL subband;

[0067] □The entire bandwidth of this symbol (corresponding to the BWP) can be used for uplink transmission.

[0068] If the terminal device and the network device have different understandings of the bandwidth for uplink transmission within the symbol, normal communication will not be possible within the symbol.

[0069] Please refer to FIG3 , which shows a flow chart of a resource determination method provided by an embodiment of the present application. The method is executed by a terminal device and may include at least one of the following steps 310 to 320 .

[0070] In step 310, the terminal device determines N first time domain units, where the first frequency domain resources corresponding to the first time domain units include a first subband, the type of the first subband is a first type, the first type is uplink or downlink, and N is a positive integer.

[0071] In some embodiments, the first frequency domain resource is a carrier bandwidth or a cell bandwidth or a bandwidth part (BWP).

[0072] In some embodiments, the time domain unit may be divided with a time slot, a subframe, or a symbol as a granularity. For example, a time slot is a time domain unit, or a subframe is a time domain unit, or a symbol is a time domain unit. In some embodiments, the time domain unit may be divided with a time slot group, a subframe group, or a symbol group as a granularity. For example, a time slot group is a time domain unit, and a time slot group includes at least one time slot. For example, a subframe group is a time domain unit, and a subframe group includes at least one subframe. For example, a symbol group is a time domain unit, and a symbol group includes at least one symbol. The names of the time domain units may be different in different communication systems, and this application does not limit this.

[0073] In some embodiments, the first sub-band is a portion of the frequency domain resources in the first frequency domain resources, that is, the bandwidth of the first sub-band is less than or equal to the bandwidth of the first frequency domain resources. The first sub-band can be located in the middle of the frequency domain bandwidth corresponding to the first time domain unit, or can be located on both sides of the frequency domain bandwidth corresponding to the first time domain unit, and this application does not limit this. For example, as shown in Figure 2, the type of the first sub-band is uplink, and the type of the first time domain unit is downlink. The first sub-band can be located in the middle of the frequency domain bandwidth corresponding to the first time domain unit, or can be located on both sides of the frequency domain bandwidth corresponding to the first time domain unit.

[0074] In some embodiments, the first time domain unit may be referred to as an SBFD time domain unit. For example, the first time domain unit may be an SBFD symbol, an SBFD time slot, or an SBFD subframe. In some embodiments, the first time domain unit may be referred to as a hybrid time domain unit, i.e., the first time domain unit includes at least two of uplink frequency domain resources, downlink frequency domain resources, flexible frequency domain resources, and gap frequency domain resources.

[0075] In some embodiments, the frequency domain bandwidth corresponding to the first time domain unit also includes a second sub-band. In some embodiments, the type of the second sub-band is the second type, and the first type is different from the second type. In some embodiments, the second type is uplink or downlink or gap. Exemplarily, the first type is uplink, and the second type is downlink. Exemplarily, the first type is downlink, and the second type is uplink. Exemplarily, as shown in FIG4 , if the first type is uplink, or the first sub-band 410 is used for uplink transmission, the type of the time domain unit 420 is downlink, or the time domain unit 420 is used for downlink transmission, or the time domain unit 420 is a downlink time domain unit. Exemplarily, as shown in FIG4 , if the first type is downlink, or the first sub-band 410 is used for downlink transmission, the type of the time domain unit 420 is uplink, or the time domain unit 420 is used for uplink transmission, or the time domain unit 420 is an uplink time domain unit.

[0076] In some embodiments, the second subband is not configured for uplink transmission or downlink transmission. Exemplarily, the first type is uplink, and the second subband is not configured for uplink transmission or downlink transmission. Exemplarily, the first type is downlink, and the second subband is not configured for uplink transmission or downlink transmission. Exemplarily, as shown in FIG4 , if the first type is uplink, or the first subband 410 is used for uplink transmission, the time domain unit 430 is a flexible time domain unit. Exemplarily, as shown in FIG4 , if the first type is downlink, or the first subband 410 is used for downlink transmission, the time domain unit 430 is a flexible time domain unit.

[0077] In step 320 , the terminal device receives first information, where the first information is used to indicate the types of M time domain units among the N first time domain units, where the M time domain units meet agreed restrictions and M is a positive integer.

[0078] Accordingly, the network device sends the first information to the terminal device.

[0079] In some embodiments, the first information is used to indicate that the type of M time domain units among the N first time domain units is one of uplink, downlink, or flexible.

[0080] In some embodiments, the N first time domain units include a first type of first time domain unit and a second type of first time domain unit. The type of the second subband in the first type of first time domain unit is different from the type of the first subband. Exemplarily, the type of the first type of first time domain unit is indicated as downlink or uplink in the TDD uplink and downlink common configuration (TDD-UL-DL-ConfigCommon) information. The second subband in the second type of first time domain unit is not configured for uplink transmission or downlink transmission. Exemplarily, the type of the second type of first time domain unit is indicated as flexible in the TDD uplink and downlink common configuration (TDD-UL-DL-ConfigCommon) information. In some embodiments, the M time domain units are M second type of first time domain units. Exemplarily, the type of the M time domain units is indicated as flexible in the TDD uplink and downlink common configuration (TDD-UL-DL-ConfigCommon) information.

[0081] In some embodiments, the first information may be TDD uplink and downlink dedicated configuration (TDD-UL-DL-ConfigDedicated) information, or may be SFI, or may be DCI format 2_0.

[0082] In some embodiments, the M time-domain units satisfy the agreed restrictions as one of the following:

[0083] The type of the M time domain units is the first type;

[0084] The types of the M time-domain units are other types than the first type;

[0085] The type of M time-domain units is not valid.

[0086] In some embodiments, the first time domain unit includes a first subband and a second subband, and the type of the second subband is different from the type of the first subband. In some embodiments, if the first subband is used for uplink transmission, the first time domain unit is a downlink time domain unit or a flexible time domain unit; if the first subband is used for downlink transmission, the first time domain unit is an uplink time domain unit or a flexible time domain unit. Therefore, the terminal device can determine the first time domain unit based on the types of the M time domain units indicated in the first information and the above conditions. Exemplarily, if the type of the M time domain units is the first type, then the M time domain units are no longer the first time domain units, and the first time domain unit will be updated to the first time domain unit other than the M time domain units in the N first time domain units. Exemplarily, if the type of the M time domain units is other than the first type, then the M time domain units still meet the above conditions, and then the M time domain units are still the first time domain units.

[0087] In some embodiments, the terminal device may execute step 310 before step 320 or after step 320, which is not limited in this application.

[0088] The technical solution provided in the embodiments of the present application uses first information to indicate the types of M time domain units that meet agreed restrictions. Based on the types of the M time domain units indicated in the first information, the terminal device can determine at least one first time domain unit among the N first time domain units, where the at least one first time domain unit includes the first subband. By using agreed restrictions, the terminal device and the network device can unify their understanding of the M time domain units, avoiding situations where communication cannot be established within the M time domain units.

[0089] This application provides exemplary embodiments for several situations where M time domain units meet the agreed restrictions.

[0090] Case 1: The type of M time domain units is the first type

[0091] In some embodiments, if the first sub-band is used for uplink transmission, the M time domain units are uplink time domain units. In some embodiments, if the first sub-band is used for downlink transmission, the M time domain units are downlink time domain units.

[0092] In some embodiments, if the type of the M time domain units is the first type, the terminal device removes the M time domain units from the N first time domain units, and the remaining (NM) time domain units serve as first time domain units, and the M time domain units are no longer first time domain units.

[0093] In some embodiments, within a first time domain unit other than the M time domain units, the frequency domain resources occupied by the first type of transmission do not exceed the first sub-band. In some embodiments, within the first time domain unit other than the M time domain units, the frequency domain resource range of the first type of transmission is less than or equal to the first sub-band. In some embodiments, within the first time domain unit other than the M time domain units, the frequency domain resources occupied by the first type of transmission are located within the first sub-band. In some embodiments, within the M time domain units, the frequency domain resources occupied by the first type of transmission do not exceed the first frequency domain resources. In some embodiments, within the M time domain units, the frequency domain resource range occupied by the first type of transmission is equal to the first frequency domain resources. In some embodiments, within the M time domain units, the frequency domain resources occupied by the first type of transmission are located within the first frequency domain resources.

[0094] Exemplarily, as shown in FIG5 , the first information is used to indicate the types of the M time domain units. If the first subband is used for uplink transmission, and the first information indicates that the type of the M time domain units is uplink, then within the M time domain units, the frequency domain resources occupied by the uplink transmission do not exceed the first frequency domain resources, and within the first time domain unit other than the M time domain units, the frequency domain resources occupied by the uplink transmission do not exceed the first subband.

[0095] In some embodiments, after removing M time domain units from the N first time domain units, L groups of consecutive first time domain units are obtained, where L is less than or equal to the first value.

[0096] In some embodiments, the first value may be predefined or preconfigured, or may be determined based on the capabilities of the terminal device, which is not limited in this application. This application does not limit the specific value of the first value. For example, the first value is 1 or 2.

[0097] In some embodiments, after treating M time domain units as non-first time domain units, M time domain units are removed from N first time domain units and regarded as first time domain units, the number of switching points in the at least one time domain period is less than or equal to the second value. The switching point refers to the position where the first time domain unit switches to a non-first time domain unit, or the position where the non-first time domain unit switches to a first time domain unit. In some embodiments, the second value may be predefined or preconfigured, or may be determined based on the capabilities of the terminal device, which is not limited in this application. This application does not limit the specific value of the second value. For example, the second value is 2 or 4. In some embodiments, the second value is twice the first value.

[0098] In some embodiments, the M time domain units may be M consecutive time domain units, or may be any M time domain units among the N first time domain units. In the following embodiments of the present application, several possible examples of the distribution of the M time domain units among the N first time domain units are given.

[0099] 1. The M time domain units are the last M first time domain units among the N first time domain units.

[0100] In some embodiments, the M time domain units are the last M first time domain units among the N first time domain units. After removing M time domain units from the N first time domain units, a group of continuous first time domain units is obtained. Within this time domain period, the number of switching points is 2. For example, as shown in FIG6 , the first subband is used for uplink transmission, the M time domain units are the last M first time domain units among the N first time domain units. After removing M time domain units from the N first time domain units, a group of continuous first time domain units 610 is obtained. Starting from the time domain units on the left side of FIG6 , the switching points include the position where the downlink time domain unit switches to the first time domain unit (the left boundary position of the continuous first time domain units 610), and the position where the first time domain unit switches to M time domain units (the right boundary position of the continuous first time domain units 610).

[0101] In some embodiments, the M time domain units are M second-type first time domain units. If the second-type first time domain unit is located after the first-type first time domain unit, the M time domain units are the last M second-type first time domain units in the N first time domain units. After removing M time domain units from the N first time domain units, a group of continuous first time domain units is obtained. Within this time domain period, the number of switching points is 2. For example, as shown in FIG6 , the first subband is used for uplink transmission, the M time domain units are the last M flexible time domain units in the N first time domain units, and after removing M time domain units from the N first time domain units, a group of continuous first time domain units 610 is obtained. Starting from the time domain units on the left side of FIG6 , the switching points include the position where the downlink time domain unit switches to the first time domain unit (the left boundary position of the continuous first time domain units 610) and the position where the first time domain unit switches to M time domain units (the right boundary position of the continuous first time domain units 610).

[0102] In some embodiments, the M time domain units are M second-type first time domain units. If the second-type first time domain unit is located before the first-type first time domain unit, the M time domain units are the last M second-type first time domain units in the N first time domain units. After removing M time domain units from the N first time domain units, two consecutive groups of first time domain units are obtained. Within this time domain period, the number of switching points is 4. For example, as shown in FIG7 , the first subband is used for downlink transmission, the M time domain units are the last M second-type first time domain units in the N first time domain units, and after removing M time domain units from the N first time domain units, two consecutive groups of first time domain units 710 and 720 are obtained. Starting from the time domain unit on the left side of Figure 7, the switching points include the position where the downlink time domain unit switches to the first time domain unit (the left boundary position of the continuous first time domain unit 710), the position where the first time domain unit switches to M time domain units (the right boundary position of the continuous first time domain unit 710), the position where M time domain units switch to the first time domain unit (the left boundary position of the continuous first time domain unit 720), and the position where the first time domain unit switches to the uplink time domain unit (the right boundary position of the continuous first time domain unit 720).

[0103] 2. The M time domain units are the first M first time domain units among the N first time domain units

[0104] In some embodiments, the M time domain units are the first M first time domain units among the N first time domain units. After removing M time domain units from the N first time domain units, a group of continuous first time domain units is obtained. Within this time domain period, the number of switching points is 2. For example, as shown in FIG8 , the first subband is used for downlink transmission, the M time domain units are the first M first time domain units among the N first time domain units. After removing M time domain units from the N first time domain units, a group of continuous first time domain units 810 is obtained. Starting from the time domain units on the left side of FIG8 , the switching points include the position where the M time domain units switch to the first time domain units (the left boundary position of the continuous first time domain units 810) and the position where the first time domain units switch to the uplink time domain units (the right boundary position of the continuous first time domain units 810).

[0105] In some embodiments, the M time domain units are M second-type first time domain units. If the second-type first time domain unit precedes the first-type first time domain unit, the M time domain units are the first M second-type first time domain units among the N first time domain units. After removing M time domain units from the N first time domain units, a group of continuous first time domain units is obtained. Within this time domain period, the number of switching points is 2. For example, as shown in FIG8 , the first subband is used for downlink transmission, the M time domain units are the first M flexible time domain units among the N first time domain units, and after removing M time domain units from the N first time domain units, a group of continuous first time domain units 810 is obtained. Starting from the time domain units on the left side of FIG8 , the switching points include the position where the M time domain units switch to the first time domain units (the left boundary of the continuous first time domain units 810) and the position where the first time domain units switch to the uplink time domain units (the right boundary of the continuous first time domain units 810).

[0106] In some embodiments, the M time domain units are M second-type first time domain units. If the second-type first time domain unit is located before the first-type first time domain unit, the M time domain units are the first M second-type first time domain units in the N first time domain units. After removing M time domain units from the N first time domain units, two consecutive groups of first time domain units are obtained. Within this time domain period, the number of switching points is 4. For example, as shown in FIG9 , the first subband is used for uplink transmission, the M time domain units are the first M second-type first time domain units in the N first time domain units, and after removing M time domain units from the N first time domain units, two consecutive groups of first time domain units 910 and 920 are obtained. Starting from the time domain unit on the left side of Figure 9, the switching points include the position where the downlink time domain unit switches to the first time domain unit (the left boundary position of the continuous first time domain unit 910), the position where the first time domain unit switches to M time domain units (the right boundary position of the continuous first time domain unit 910), the position where M time domain units switch to the first time domain unit (the left boundary position of the continuous first time domain unit 920), and the position where the first time domain unit switches to the uplink time domain unit (the right boundary position of the continuous first time domain unit 920).

[0107] 3. The M time domain units are any M first time domain units among the N first time domain units.

[0108] In some embodiments, the M time domain units are any M first time domain units among the N first time domain units. The M time domain units can be a continuous group of M time domain units, or multiple groups of time domain units totaling M. The time domain units in each group are continuous, and any two groups of time domain units are discontinuous. For the case of a continuous group of M time domain units, reference can be made to the examples corresponding to Figures 6 to 9 above, and this application will not go into details. For the case of multiple groups of time domain units totaling M, as shown in Figure 10, the first information is used to indicate the type of time domain units in the time domain unit groups 1030 and 1040. The first subband is used for uplink transmission. After removing M time domain units from the N first time domain units, two groups of continuous first time domain units 1010 and 1020 are obtained. Within this time domain period, the number of switching points is 4. Starting from the time domain unit on the left side of FIG10 , the switching points include the position where M time domain units switch to the first time domain unit (the left boundary of the consecutive first time domain units 1010), the position where the first time domain unit switches to M time domain units (the right boundary of the consecutive first time domain units 1010), the position where M time domain units switch to the first time domain unit (the left boundary of the consecutive first time domain units 1020), and the position where the first time domain unit switches to the uplink time domain unit (the right boundary of the consecutive first time domain units 1020). In some embodiments, the M time domain units are any M second-type first time domain units among the N first time domain units. As shown in FIG10 , the first information is used to indicate the type of time domain units in the time domain unit groups 1010 and 1020. The first subband is used for uplink transmission. After removing M time domain units from the N first time domain units, two groups of consecutive first time domain units 1030 and 1040 are obtained. The number of switching points within this time domain period is four. Starting from the time domain unit on the left side of Figure 10, the switching points include the position where the downlink time domain unit switches to the first time domain unit (the left boundary position of the continuous first time domain unit 1030), the position where the first time domain unit switches to M time domain units (the right boundary position of the continuous first time domain unit 1030), the position where M time domain units switch to the first time domain unit (the left boundary position of the continuous first time domain unit 1040), and the position where the first time domain unit switches to M time domain units (the right boundary position of the continuous first time domain unit 1040).

[0109] Since switching points introduce certain time domain gaps or transmission interruptions, the above method can be used to control the number of switching points within a time domain cycle. If the number of switching points within a time domain cycle is controlled to 2, the terminal device implementation is relatively simple and the system efficiency is high, but flexibility is limited. However, if the number of switching points is controlled to be greater than 2, a certain degree of flexibility can be achieved. Therefore, the number of switching points (determining the first value and / or the second value) can be determined based on the capabilities of the terminal device.

[0110] Case 2: The types of the M time domain units are other than the first type

[0111] In some embodiments, if the type of the M time domain units is other than the first type, the M time domain units can still serve as the first time domain units. In some embodiments, within the N first time domain units, the frequency domain resources occupied by the first type of transmission do not exceed the first sub-band. In some embodiments, within the N first time domain units, the frequency domain resource range of the first type of transmission is less than or equal to the first sub-band. In some embodiments, within the N first time domain units, the frequency domain resources of the first type of transmission are located within the first sub-band.

[0112] In some embodiments, if the first subband is used for uplink transmission, the M time domain units are downlink time domain units or flexible time domain units.

[0113] In some embodiments, if the first subband is used for downlink transmission, the M time domain units are uplink time domain units or flexible time domain units.

[0114] In some embodiments, if the first subband is used for uplink transmission, the terminal device does not expect M time domain units to be uplink time domain units.

[0115] In some embodiments, if the first subband is used for downlink transmission, the terminal device does not expect M time domain units to be downlink time domain units.

[0116] Exemplarily, as shown in Figure 6, if the first subband is used for uplink transmission, M time domain units are configured as downlink time domain units or flexible time domain units by the first information; if the first subband is used for downlink transmission, M time domain units are configured as uplink time domain units or flexible time domain units by the first information.

[0117] Through the above method, configuration restrictions on the network device side are introduced, making the terminal device implementation the simplest, but compared with the first case, the flexibility is poor.

[0118] Case 3: The indication information of the type of M time domain units is not effective

[0119] In some embodiments, the terminal device does not use the indication information for the types of the M time domain units in the first information, or the terminal device does not read the indication information for the types of the M time domain units in the first information, or the terminal device ignores the indication information for the types of the M time domain units in the first information, or the terminal device skips the indication information for the types of the M time domain units in the first information, or the indication information for the types of the M time domain units in the first information is reserved.

[0120] Through the above method, the terminal device performs a simple judgment on the first information, and the implementation of the terminal device is still relatively simple. Similarly, compared with the first situation, the flexibility is poor.

[0121] Regarding how the terminal device determines N first time domain units, this application provides an exemplary embodiment.

[0122] In some embodiments, the method further includes at least one of the following steps 330 to 340 .

[0123] Step 330: The terminal device determines N first time domain units.

[0124] In some embodiments, the terminal device determines the N first time domain units according to an agreed rule, and the terminal device may also determine the N first time domain units according to the second information. Accordingly, the network device sends the second information to the terminal device.

[0125] Step 340: The type of each time domain unit in the N first time domain units of the terminal device.

[0126] In some embodiments, the terminal device determines N first time domain units according to an agreed rule, and the terminal device may also determine the type of each of the N first time domain units based on third information. In some embodiments, the terminal device determines the type of each of a plurality of time domain units based on the third information, where the plurality of time domain units includes the N first time domain units. Accordingly, the network device sends the third information to the terminal device.

[0127] In some embodiments, the N first time domain units or the plurality of time domain units have a time domain period, which may also be a pattern period. In some embodiments, the length of a time domain period is divisible by 20 ms. Exemplarily, the length of a time domain period is 4 ms, or the length of a time domain period is 5 ms.

[0128] In some embodiments, the type of the time domain unit is one of uplink, downlink or flexible. In some embodiments, if the type of the time domain unit is uplink, the time domain unit may be referred to as an uplink time domain unit, or the time domain unit is used for uplink transmission. Exemplarily, if the type of the symbol is uplink, the symbol may be referred to as an uplink symbol, or the symbol is used for uplink transmission. In some embodiments, if the type of the time domain unit is downlink, the time domain unit may be referred to as a downlink time domain unit, or the time domain unit is used for downlink transmission. Exemplarily, if the type of the symbol is downlink, the symbol may be referred to as a downlink symbol, or the symbol is used for downlink transmission. In some embodiments, if the type of the time domain unit is flexible, the time domain unit may be referred to as a flexible time domain unit, or the time domain unit is used for flexible transmission. Exemplarily, if the type of the symbol is flexible, the symbol may be referred to as a flexible symbol, or the symbol is used for flexible transmission.

[0129] In some embodiments, the third information may be TDD uplink and downlink common configuration (TDD-UL-DL-ConfigCommon) information.

[0130] In some embodiments, the second information and the third information may be sent simultaneously or separately, and this application does not limit this. Exemplarily, the second information and the third information are separate and independent information, and both are sent simultaneously. Exemplarily, the second information is carried in the third information. Exemplarily, the third information is carried in the second information. Exemplarily, the second information and the third information are separate and independent information, and the two are not sent simultaneously. In some embodiments, the third information is transmitted before the first information. In some embodiments, this application does not limit the order of the second information and the third information. In some embodiments, this application does not limit the order of the first information and the second information.

[0131] In some embodiments, the terminal device determines at least one uplink time domain unit, at least one downlink time domain unit, and at least one flexible time domain unit within a time domain period based on the third information. The terminal device determines N first time domain units based on the second information.

[0132] In some embodiments, the N first time domain units include at least one second type of first time domain unit.

[0133] In some embodiments, the second information may be sent simultaneously with the third information. For example, the second information may be sent simultaneously with TDD-UL-DL-ConfigCommon. For example, TDD-UL-DL-ConfigCommon includes the second information.

[0134] In some embodiments, the second information and the third information are sent as independent information, for example, the second information and TDD-UL-DL-ConfigCommon are sent as independent information.

[0135] In some embodiments, if the first subband is used for uplink transmission, the indication result of the second information only includes downlink time domain units and / or flexible time domain units; if the first subband is used for downlink transmission, the indication result of the second information only includes uplink time domain units and / or flexible time domain units.

[0136] In some embodiments, the indication result of the second information includes an uplink time domain unit, a downlink time domain unit, and a flexible time domain unit, and the terminal device determines N first time domain units based on the type of the first subband and the second information. Exemplarily, if the first subband is used for uplink transmission, the terminal device determines the downlink time domain unit and / or the flexible time domain unit indicated by the second information as the first time domain unit; if the first subband is used for downlink transmission, the terminal device determines the uplink time domain unit and / or the flexible time domain unit indicated by the second information as the first time domain unit.

[0137] Through the above method, the terminal device can determine N first time domain units.
