Network elements can be virtual or physical. The core network includes, for example, at least one of the Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

[0171] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0172] In some embodiments, terminal 101 is connected to core network device 102-2 via access network device 102-1.

[0173] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0174] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A.

[0175] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), 6th generation mobile communication system (6G), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, systems utilizing other communication methods, and next-generation systems based on them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0176] In the SBFD scenario, the base station configures a UL subband on the downlink (DL) time unit or the flexible time unit. The terminal can transmit uplink information on the UL subband. The time and frequency domain resources occupied by the UL subband can be determined by the display configuration, as shown in Figure 1B.

[0177] From another perspective, the time-domain resources of Time Division Duplexing (TDD) can be indicated based on static or dynamic signaling. For example, this signaling can indicate time-domain resources by configuring one or more TDD patterns. For a specific TDD pattern, it can be determined based on at least one of the following information:

[0178] TDD pattern corresponding period;

[0179] The number of downlink slots and / or downlink symbols contained within the period;

[0180] The number of uplink slots and / or uplink symbols contained within the period;

[0181] Reference Sub-Carrier Space (SCS).

[0182] For SBFD time-domain resources indicated by static signaling, they can be indicated based on a TDD pattern. For the TDD pattern corresponding to the SBFD time-domain resource, the corresponding period is determined based on at least one of the following methods:

[0183] The period is equal to the existing TDD pattern configuration period;

[0184] The period is equal to an integer multiple of the existing TDD pattern configuration period.

[0185] Among them, the existing TDD pattern configuration period is configured based on the uplink and downlink transmission period (DL-UL-TransmissionPeriodicity) parameter in the Time Division Duplex Uplink and Downlink Common Configuration (TDD-UL-DL-ConfigCommon).

[0186] The SBFD time-domain location within the TDD pattern period corresponding to the SBFD time-domain resource can be indicated in the following way:

[0187] With only one TDD pattern configured, the corresponding SBFD time unit can be configured continuously within the TDD pattern period;

[0188] When two TDD patterns are configured and SBFD time-domain resources are configured within one of the TDD patterns, the corresponding SBFD symbols can be configured in a continuous manner within the corresponding TDD pattern period.

[0189] With two TDD patterns configured and SBFD time-domain resources configured in both TDD patterns, the corresponding SBFD time units are configured in a continuous manner within the corresponding TDD pattern period.

[0190] The SBFD time unit is based on the DL or Flexible (F) time unit configuration within the existing TDD configuration, and the corresponding SBFD symbol can start with any symbol within the time slot and end with any symbol within the time slot.

[0191] In this embodiment of the disclosure, TDD includes the following three time-domain structures: uplink (UL), downlink (DL), and flexible (F) time units. The F time unit can be changed to UL or downlink DL time units based on other signaling, and can also be used for terminal transmission and reception conversion.

[0192] For cell-level TDD configuration, it can be configured through TDD-UL-DL-ConfigCommon signaling. This signaling can configure one or more TDD patterns. For a specific TDD pattern, it mainly includes the following parameters: reference subcarrier spacing; period P; downlink slot number dslot; downlink symbol number dsym; uplink slot number uslot; uplink symbol number usym.

[0193] The reference subcarrier spacing and period P determine the total number of time slots Q contained in the period. The first dslots of the Q time slots represent all downlink time slots, and the first dsyms of the time slot following the last all downlink time slot represent downlink symbols. The last uslots of the Q time slots represent all uplink time slots, and the last usyms of the time slot preceding the first all uplink time slot represent uplink symbols. The remaining symbols in the period are F symbols.

[0194] Taking Q=10, dslot=2, dsym=0, uslot=2, usym=0 as an example, the corresponding TDD configuration is described in Figure 1C. Among them, slot#0 and slot#1 are downlink slots, slot#2 to slot#7 are flexible slots, and slot#8 and slot#9 are uplink slots.

[0195] Network devices can configure two patterns simultaneously via TDD-UL-DL-ConfigCommon signaling. The periods of the two patterns are P1 and P2, and the two patterns repeat together in the time domain. That is, the TDD configuration period is (P1+P2), and they repeat periodically in the time domain. An exemplary scenario is shown in Figure 1D.

[0196] In this embodiment of the disclosure, the TDD pattern period can refer to the period corresponding to a TDD pattern. For example, in Figure 1D, the period corresponding to TDD pattern #1 is P1, and the period corresponding to TDD pattern #2 is P2.

[0197] The TDD configuration cycle refers to the cycle corresponding to a complete TDD configuration. Each TDD configuration may include one or more TDD patterns. For example, in Figure 1D, the TDD configuration includes TDD pattern #1 and TDD pattern #2, and the TDD configuration cycle is (P1+P2).

[0198] In the embodiments of this disclosure, although it can be determined that the uplink sub-band or downlink sub-band can occupy one or more consecutive time units in the time domain, wherein the time unit can be a symbol, slot, sub-slot, frame, subframe, etc., its specific time domain resources and period cannot be determined.

[0199] Here, a subslot is a time unit with a length shorter than a slot. A subslot may contain n symbols, where n can be a positive integer less than 14. n can be determined based on a predefined method or indicated by the network device via signaling, such as subslotLengthForPUCCH; this disclosure does not limit this determination.

[0200] In order to determine the specific time-domain resources occupied by the first sub-band and improve the availability and reliability of SBFD, this disclosure provides the following method, apparatus, and storage medium for determining resources.

[0201] Figure 2 is an interactive schematic diagram illustrating a method for determining resources according to an embodiment of the present disclosure. As shown in Figure 2, this disclosure relates to a method for determining resources, the method including:

[0202] In step S2101, network device 102 sends a third signaling message to terminal 101.

[0203] In some embodiments, third signaling may include, but is not limited to, at least one of the following:

[0204] Radio Resource Control (RRC) signaling;

[0205] Media Access Control Element (MAC CE);

[0206] Downlink Control Information (DCI).

[0207] In one example, the third signaling can be RRC signaling, such as TDD-UL-DL-ConfigCommon signaling. Of course, the third signaling can also be RRC signaling specific to terminal 101, and this disclosure does not limit it in this way.

[0208] In some embodiments, the third signaling may be used to indicate the size of the first time window.

[0209] In some embodiments, the first time window can be understood as the period length of the first sub-band.

[0210] That is, the first sub-band can be transmitted based on the same temporal resource pattern within each first time window.

[0211] For example, the first sub-band can be transmitted based on the same time-domain resource pattern within each first time window, which can be understood as: the index and / or position of the time-domain resource corresponding to the first sub-band is the same within each first time window.

[0212] For example, assume that each first time window occupies 2 time slots, and each time slot includes 14 symbols, that is, there are 28 symbols in each period. The uplink subband occupies the time domain resources of symbols #1 to #20 in the first time window #1, symbols #1 to #20 in the first time window #2, and so on, as shown in Figure 4A.

[0213] In some embodiments, the first subband may be an uplink subband (UL subband).

[0214] In an SBFD scenario, the terminal can be configured to transmit uplink information on the UL subband within the SBFD time unit. The frequency domain resources of the UL subband can be determined based on configuration or a predefined method.

[0215] In some embodiments, the first sub-band can be a downlink sub-band. The frequency domain resource range corresponding to the downlink sub-band can be determined at the SBFD time unit based on the frequency domain resource range outside the uplink sub-band.

[0216] For example, the frequency domain resource range outside the uplink sub-band includes the frequency domain resource range corresponding to the downlink sub-band and the frequency domain resource range corresponding to the guard band (GB).

[0217] The determination of time domain resources for uplink and downlink subbands is similar. The following explanation will take the example of the first subband being the uplink subband. It is understood that the scheme for determining the time domain resources occupied by the subband in the first time window can also be applied to downlink subbands, GB, etc., and this disclosure does not limit it.

[0218] In one example, an SBFD time unit can refer to an uplink time unit, downlink time unit, or flexible time unit configured for a UL subband and / or a DL subband. For example, in Figure 1B, the second type of time unit can include slot#(n+1), slot#(n+2), and slot#(n+3).

[0219] In some embodiments, the first time window may satisfy any of the following:

[0220] The duration is equal to the duration of a time division multiplexing (TDD) configuration period, and each time division multiplexing configuration period includes one or more time division multiplexing patterns;

[0221] The included time-domain resources are the same as those included in a TDD configuration cycle;

[0222] The duration is equal to the duration of one TDD pattern cycle;

[0223] The included time-domain resources are the same as those included in a TDD pattern.

[0224] In one example, the duration of the first time window can be equal to the duration of a TDD configuration period, which may include one or more time-division multiplexing patterns.

[0225] For example, as shown in Figure 4B, a TDD configuration cycle includes two TDD patterns, pattern #1 and pattern #2. The size of the first time window can be equal to the duration of the TDD configuration cycle, that is, each first time window includes the two TDD patterns mentioned above.

[0226] In one example, the time-domain resources included in the first time window can be the same as those included in a TDD configuration period, where a TDD configuration period can include one or more time-division multiplexing patterns. In this case, the first time window is the TDD configuration period. For example, in Figure 4B, the first time window is the TDD configuration period.

[0227] In one example, the duration of the first time window can be equal to the duration of a time-division multiplexing pattern cycle. For instance, the duration of the first time window can be equal to the duration of the cycle of TDD pattern #1 in Figure 4B, comprising 3 time slots. Alternatively, the duration of the first time window can be equal to the duration of the cycle of TDD pattern #2 in Figure 4B, comprising 2 time slots.

[0228] In one example, the time-domain resources included in the first time window can be the same as those included in a TDD pattern. For example, in Figure 4B, the first time window is the period of TDD pattern #1 or the period of TDD pattern #2.

[0229] In some embodiments, the size of the first time window can be determined in the manner described above. Alternatively, the starting time domain position of the first time window can be determined in the following ways: for example, it can be configured by the network device 102 through signaling, or it can be determined based on a predefined method.

[0230] In one example, the starting time domain position of the first time window is configured based on the fourth signaling sent by network device 102.

[0231] For example, the fourth signaling can be used to indicate the time unit index where the starting time domain position of the first time window is located, for example, directly indicating the starting time slot index, starting symbol index, starting sub-time slot index, or starting frame index of the first time window.

[0232] For example, the fourth signaling can indicate the period P of the first time window, and the terminal 101 takes the first time slot or the first sub-time slot as the starting time unit of the first time window, and determines the starting time unit position of the next first time window according to P.

[0233] For example, the fourth signaling may indicate an offset, which may be an offset relative to a reference time domain position, which may be determined by the network device based on signaling indication or based on a predefined method. In addition, the offset may be in units of symbols, sub-slots, time slots, frames, subframes, etc., which are not limited in this disclosure.

[0234] In one example, the starting time domain position of the first time window can be determined based on a predefined method. For example, network device 102 can align the starting time domain position of the first time window with frames, subframes, sub-time slots, time slots, etc. by default.

[0235] The above is merely an illustrative example, and this disclosure does not limit the scheme for determining the starting time domain position of the first time window.

[0236] In some embodiments, terminal 101 receives the third signaling.

[0237] In step S2102, terminal 101 determines the first time window.

[0238] In some embodiments, terminal 101 determines the size of the first time window based on third signaling sent by network device 102.

[0239] Third signaling can be used to instruct at least one of the following:

[0240] The duration of the first time window is equal to the duration of a TDD configuration cycle, and each time division multiplexing configuration cycle includes one or more time division multiplexing patterns;

[0241] The time-domain resources included in the first time window are the same as those included in a TDD configuration cycle;

[0242] The duration of the first time window is equal to the duration of a TDD pattern cycle;

[0243] The time-domain resources included in the first time window are the same as those included in a TDD pattern.

[0244] For example, the third signaling is used to indicate that the time domain resources included in the first time window are the same as the time domain resources included in a TDD configuration period, or the same as the time domain resources included in a time division multiplexing pattern. The terminal 101 can directly determine the size of the first time window based on the third signaling.

[0245] In some embodiments, terminal 101 may determine the starting time domain position of the first time window based on the fourth signaling sent by network device 102. For example, the fourth signaling may be used to indicate at least one of the following: the time unit index where the starting time domain position of the first time window is located; the period duration of the first time window; and the offset of the starting time domain position of the first time window relative to a reference time domain position.

[0246] The fourth signaling may be the same as or different from the third signaling; this disclosure does not limit this.

[0247] In some embodiments, terminal 101 may determine the size of the first time window based on a predefined method.

[0248] In some embodiments, terminal 101 may determine at least one of the following based on a predefined method:

[0249] The duration of the first time window is equal to the duration of a TDD configuration cycle, and each time division multiplexing configuration cycle includes one or more time division multiplexing patterns;

[0250] The time-domain resources included in the first time window are the same as those included in a TDD configuration cycle;

[0251] The duration of the first time window is equal to the duration of a TDD pattern cycle;

[0252] The time-domain resources included in the first time window are the same as those included in a TDD pattern.

[0253] In one example, the protocol can directly stipulate that the first time window is the same as a time division multiplexing (TDD) configuration period, or that the first time window is the same as a TDD pattern period. Terminal 101 can determine the size of the first time window based on a predefined method.

[0254] In one example, the size of the first time window can be directly agreed upon by the protocol as either a system frame or a system half-frame, and the terminal 101 determines the size of the first time window based on the predefined method.

[0255] In some embodiments, terminal 101 may determine the size of the first time window based on third signaling and a predefined method.

[0256] In one example, terminal 101 determines that the first time window includes Q time units or sub-time units based on a predefined method. Terminal 101 receives a third signaling sent by network device 102, which indicates the value of Q. Terminal 101 determines the size of the first time window based on the predefined method and the third signaling.

[0257] In some embodiments, the terminal 101 may determine that the time units included in the first time window are in units such as frames, subframes, time slots, symbols, sub-time slots, etc., and this disclosure does not limit this.

[0258] The above is merely an illustrative example, and this disclosure does not limit the method by which the terminal 101 determines the size of the first time window.

[0259] In some embodiments, terminal 101 may determine the starting time-domain position of the first time window based on a predefined method. For example, terminal 101 may determine the time unit index where the starting time-domain position of the first time window is located based on a predefined method. Alternatively, it may determine the period duration of the first time window based on a predefined method, and then determine the starting time-domain position of each first time window. Alternatively, it may determine the offset of the starting time-domain position of the first time window relative to a reference time-domain position based on a predefined method, thereby determining the starting time-domain position of the first time window.

[0260] In some embodiments, terminal 101 may determine the size of the first time window and / or the starting time domain position based on at least one of third signaling, fourth signaling, and a predefined method. The specific determination method has been described in the foregoing embodiments and will not be repeated here.

[0261] In step S2103, network device 102 sends the first signaling to terminal 101.

[0262] In some embodiments, the first signaling may include, but is not limited to, at least one of the following: RRC signaling; MAC CE; DCI.

[0263] In some embodiments, the first signaling may be the same signaling as the aforementioned third signaling, or it may be a different signaling; this disclosure does not limit this.

[0264] In some embodiments, the first signaling may be used to indicate the time domain resources occupied by the first sub-band within a first time window.

[0265] In some embodiments, the first signaling may be used to instruct at least one of the following:

[0266] First index; second index; first number; second number; first starting and length indication values ​​(SLIV); second SLIV.

[0267] In one example, the first index is the index of the first time unit. The first time unit is the starting time unit of the first sub-band within the first time window. Specifically, the starting time unit refers to the first time unit occupied by the first sub-band within the first time window.

[0268] For example, the first index is the starting symbol index of the first sub-band within the first time window.

[0269] For example, the first index is the starting slot index of the first sub-band within the first time window.

[0270] For example, the first index is the starting sub-slot index of the first sub-band within the first time window.

[0271] In one example, the second index is the index of the second time unit. The second time unit is the end time unit of the first sub-band within the first time window. The end time unit refers to the last time unit occupied by the first sub-band within the first time window.

[0272] For example, the second index is the end symbol index of the first sub-band within the first time window.

[0273] For example, the second index is the end gap index of the first sub-band within the first time window.

[0274] For example, the second index is the end sub-slot index of the first sub-band within the first time window.

[0275] The above is merely an illustrative example, and this disclosure does not limit the units of time indicated by the first index and the second index.

[0276] It is understandable that network device 102 can indicate the first index through the first signaling. For example, when the bit value corresponding to the first signaling is 010, the first index is 3.

[0277] In one example, the first number is the number of time units between the first time unit and the third time unit. The first time unit is the starting time unit of the first sub-band within the first time window, and the third time unit is the starting time unit of the first time window.

[0278] For example, the first number can be used to indicate the number of symbols that the starting symbol of the first sub-band is separated from the starting symbol of the first time window in the first time window.

[0279] For example, the first number can be used to indicate the number of time slots that the first sub-band is spaced apart from the starting time slot of the first time window relative to the starting time slot of the first time window.

[0280] For example, the first number can be used to indicate the number of sub-time slots that the first sub-band is spaced apart from the starting sub-time slot of the first time window relative to the starting sub-time slot of the first time window.

[0281] The first number can be a non-negative integer.

[0282] In one example, the second number is the number of time units between the second time unit and the fourth time unit. The second time unit is the end time unit of the first sub-band within the first time window, and the fourth time unit is the end time unit of the first time window.

[0283] For example, the second number can be used to indicate the number of symbols that the end symbol of the first sub-band is separated from the end symbol of the first time window in the first time window.

[0284] For example, the second number can be used to indicate the number of time slots that the first sub-band is separated from the end slot of the first time window by relative to the end slot of the first time window.

[0285] For example, the second number can be used to indicate the number of sub-slots that the first sub-band is separated from the end sub-slot within the first time window by relative to the end sub-slot of the first time window.

[0286] The second number can be a non-negative integer.

[0287] In one example, the first SLIV can be used to determine the first index and the third number.

[0288] Wherein, the first index is the index of the starting time unit of the first sub-band within the first time window, and the third number is the number of time units occupied by the first sub-band within the first time window.

[0289] For example, terminal 101 can determine a unique first index and a third number based on the first SLIV.

[0290] The first SLIV can be determined based on the following formulas 1 and 2:

[0291] if Then SLIV = N·(L-1) + S (Formula 1)

[0292] If 0 < L ≤ NS, then SLIV = N·(N-L+1) + (N-1-S) (Formula 2)

[0293] Where N is the number of time units included in the first time window, S is the first index, and L is the third number.

[0294] For example, the first SLIV can be used to determine the index of the starting symbol of the first sub-band within the first time window, and the number of symbols occupied by the first sub-band within the first time window.

[0295] For example, the first SLIV can be used to determine the index of the starting time slot of the first sub-band within the first time window, and the number of time slots occupied by the first sub-band within the first time window.

[0296] For example, the first SLIV can be used to determine the index of the starting sub-slot of the first sub-band within the first time window, and the number of sub-slots occupied by the first sub-band within the first time window.

[0297] In one example, the first signaling can be used to instruct the second SLIV, and the second SLIV can be used to determine the second index and the fourth number.

[0298] Wherein, the second index is the index of the starting sub-time unit of the first sub-band within the first time window, and the fourth number is the number of sub-time units occupied by the first sub-band within the first time window.

[0299] The second SLIV can be determined based on formulas 3 and 4:

[0300] if Then SLIV′=N′·(L-1)+S′ Formula 3

[0301] If 0 < L′ ≤ N′ - S′, then SLIV′ = N′·(N′ - L + 1) + (N′ - 1 - S′) (Formula 4)

[0302] Wherein, N′ is the number of sub-time units included in the first time window, S′ is the second index, specifically referring to the index of the starting sub-time unit of the first sub-band within the first time window, and L′ is the fourth number, specifically referring to the number of sub-time units occupied by the first sub-band within the first time window.

[0303] In one example, one or two integer arrays may be agreed upon by the protocol, wherein the first index and the third number may be determined by the network device 102 through the first signaling indicating the corresponding values ​​from the corresponding arrays.

[0304] For example, the protocol specifies an integer array #1, which may include n integers, such as L1 to Ln. Network device 102 indicates one of them, and terminal 101 determines the corresponding integer value as the first index. Suppose network device 102 indicates L2 through the first signaling, and the terminal determines the first index as L2.

[0305] For example, the protocol specifies an integer array #2, which can include 6 integers from 0 to 5. Network device 102 indicates one of them, and terminal 101 determines the corresponding integer value as the third number. Suppose that network device 102 indicates 2 through the first signaling, and the terminal determines the third number as 2.

[0306] The above is merely an illustrative example, and this disclosure does not limit the content of the first signaling instruction.

[0307] In some embodiments, terminal 101 receives a first signaling.

[0308] In step S2104, terminal 101 determines the time domain resources occupied by the first sub-band within the first time window.

[0309] In some embodiments, terminal 101 may determine the time-domain resource in, but is not limited to, the following ways:

[0310] Method 1: Terminal 101 determines the time domain resources occupied by the first sub-band within the first time window based on the first signaling.

[0311] In one example, the first signaling is used to indicate a first index and a second index, where the first index is the start time unit index of the first sub-band within the first time window, and the second index is the end time unit index of the first sub-band within the first time window. The time unit is defined as a symbol, time slot, sub-time slot, frame, subframe, etc.

[0312] It is understood that each time unit may also include N sub-time units. Sub-time units may be in units of symbols, time slots, sub-time slots, etc., where N may be determined based on a predefined method or configured based on the signaling sent by network device 102. This disclosure does not limit this.

[0313] Wherein, N can satisfy at least one of the following:

[0314] Divisible by M;

[0315] Divisible by M;

[0316] Divisible by Q.

[0317] Where M is a positive integer.

[0318] Where M can be a positive integer.

[0319] In one example, M can be the number of symbols in a time slot, for example, M = 14.

[0320] In one example, M may also be other positive integers, which are not limited in this disclosure.

[0321] For example, the time unit of this disclosure is a sub-time slot, and each sub-time slot includes N symbols. N can be divided by M. For example, when M is 14, N can be 2 or 7.

[0322] For example, the time unit of this disclosure is a time slot, and each time slot includes N symbols. N can be divisible by M. For example, if M is 14, N can be 14, 28, etc.

[0323] In one example, when each time unit of this disclosure includes N sub-time units, N is divisible by Q, where Q is the number of time units or sub-time units included in the first time window.

[0324] Assuming the sub-time unit is a symbol and Q is 6, meaning the first time window contains 6 symbols, and each time unit contains N symbols, where N can be 2 or 3.

[0325] The above is merely an illustrative example, and this disclosure does not limit the specific method for determining the value of N.

[0326] In this embodiment of the disclosure, all symbols included in the first time window can be sorted sequentially to determine the corresponding index value.

[0327] For example, time units are in symbols. The first time window includes two time slots and a total of 28 symbols. The symbol indices in the first time window are from 0 to 27. If the symbol indices start from 1, then the symbol indices in the first time window are from 1 to 28.

[0328] Terminal 101 can determine the first time unit and the second time unit based on the first signaling.

[0329] For example, suppose the first index is 1, the second index is 16, and the symbol indices within the first time window are 0 to 27. Based on the first signaling, terminal 101 determines that the first time unit is the second symbol within the first time window, and the second time unit is the seventeenth symbol within the first time window.

[0330] Furthermore, terminal 101 can determine the time domain resources occupied by the first sub-band within the first time window based on the first time unit and the second time unit.

[0331] For example, terminal 101 can determine that the time domain resources occupied by the first sub-band within the first time window include the following resources:

[0332] One or more consecutive time units from the beginning of the first time unit to the end of the second time unit.

[0333] For example, the time-domain resources occupied by the first subband within the first time window include 16 symbols, starting from the second symbol within the first time window and ending at the seventeenth symbol within the first time window.

[0334] In one example, the first signaling is used to indicate a first number and a second number, wherein the first number can be used to indicate the number of time units between the start time unit of the first sub-band within the first time window and the start time unit of the first time window, and the second number can be used to indicate the number of time units between the end time unit of the first sub-band within the first time window and the end time unit of the first time window. The time unit can be in units of symbols, time slots, sub-time slots, frames, or subframes.

[0335] Terminal 101 can determine the first time unit and the second time unit based on the first signaling. Further, terminal 101 can determine the time domain resources occupied by the first sub-band within the first time window based on the first time unit and the second time unit.

[0336] For example, terminal 101 can determine that the time domain resources occupied by the first sub-band within the first time window include the following resources:

[0337] One or more consecutive time units from the beginning of the first time unit to the end of the second time unit.

[0338] For example, time units are in symbols, with a first number of 1 and a second number of 2. Based on the first signaling, terminal 101 determines that the number of symbols between the first time unit and the starting symbol of the first time window (i.e., symbol #0) is 1. Therefore, the first time unit is the second symbol within the first time window. Similarly, terminal 101 can determine that the second time unit is the 24th symbol within the first time window. The time-domain resources occupied by the first sub-band within the first time window include 23 symbols, from the second symbol within the first time window to the 24th symbol within the first time window.

[0339] In one example, the first signaling is used to indicate the first number and the second index, or to indicate the first index and the second number. Terminal 101 can adopt a similar approach, first determining the first time unit and the second time unit, and then determining the time domain resources occupied by the first sub-band within the first time window based on the first time unit and the second time unit.

[0340] For example, terminal 101 can determine that the time domain resources occupied by the first sub-band within the first time window include the following resources:

[0341] One or more consecutive time units from the beginning of the first time unit to the end of the second time unit.

[0342] Method 2: Terminal 101 determines the temporal resources occupied by the first sub-band within the first time window based on a predefined method.

[0343] In one example, terminal 101 can determine a first index and a second index based on a predefined method, wherein the first index is the start time unit index of the first sub-band within the first time window, and the second index is the end time unit index of the first sub-band within the first time window. The time unit can be a symbol, time slot, sub-time slot, frame, or subframe.

[0344] Terminal 101 can determine the first time unit and the second time unit based on the first index and the second index, and then determine the time domain resources occupied by the first sub-band within the first time window based on the first time unit and the second time unit.

[0345] For example, terminal 101 can determine that the time domain resources occupied by the first sub-band within the first time window include the following resources:

[0346] One or more consecutive time units from the beginning of the first time unit to the end of the second time unit.

[0347] In one example, terminal 101 can determine the first number and the second number based on a predefined method, such as by a protocol. Based on the first number and the second number, terminal 101 determines the first time unit and the second time unit respectively. At this time, the time domain resources occupied by the first sub-band in the first time window are determined based on the first time unit and the second time unit.

[0348] For example, terminal 101 can determine that the time domain resources occupied by the first sub-band within the first time window include the following resources:

[0349] One or more consecutive time units from the beginning of the first time unit to the end of the second time unit.

[0350] In one example, terminal 101 can determine a first index and a second number, or a first number and a second index, based on a predefined method, thereby determining a first time unit and a second time unit respectively. At this time, the time domain resources occupied by the first sub-band within the first time window are determined based on the first time unit and the second time unit.

[0351] For example, terminal 101 can determine that the time domain resources occupied by the first sub-band within the first time window include the following resources:

[0352] One or more consecutive time units from the beginning of the first time unit to the end of the second time unit.

[0353] The specific implementation method is similar to the scheme by which terminal 101 determines time domain resources based on the third signaling sent by network device 102, and will not be described in detail here.

[0354] Method 3: Terminal 101 determines the time domain resources occupied by the first sub-band within the first time window based on the first signaling and a predefined method.

[0355] In one example, terminal 101 can determine the first time unit and the second time unit based on the first signaling or based on the predefined method. The time unit is defined in units such as time slots, sub-time slots, frames, and subframes.

[0356] For example, the first signaling can be used to indicate a first index and a second index, wherein the first index is the start time unit index of the first sub-band within the first time window, and the second index is the end time unit index of the first sub-band within the first time window. The time unit is in units such as time slots, sub-time slots, frames, and subframes. Terminal 101 can determine the first time unit and the second time unit based on the aforementioned first signaling.

[0357] For example, the first signaling can also be used to indicate the first index and the second number, or the first number and the second number, or the first number and the second index. The terminal 101 can determine the first time unit and the second time unit based on the first signaling.

[0358] For example, terminal 101 can determine the first time unit and the second time unit based on a predefined method.

[0359] Furthermore, terminal 101 can determine the first sub-time unit and the second sub-time unit based on the second signaling sent by the network device or based on a predefined method.

[0360] The second signaling may be the same as or different from the first signaling; this disclosure does not impose any restrictions on this.

[0361] The first sub-time unit is the starting sub-time unit of the first sub-band within the first time window. The length of the first sub-time unit is less than that of the first time unit, and it is located within the first time unit. For example, the first time unit is in units of sub-time slots, and the first sub-time unit can be in units of symbols.

[0362] The second sub-time unit is the ending sub-time unit of the first sub-band within the first time window. The length of the second sub-time unit is shorter than that of the second time unit, and it is located within the second time unit. For example, the second time unit is in units of sub-time slots, and the second sub-time unit can be in units of symbols.

[0363] For example, the second signaling may be used to instruct at least one of the following:

[0364] The index of the first sub-time unit within the first time unit;

[0365] The index of the second sub-time unit within the second time unit.

[0366] For example, the second signaling can indicate the index of the first sub-time unit in the form of a bitmap. For instance, if the bitmap indicated by the second signaling is 00010000000000, then the index of the first sub-time unit is 3.

[0367] For example, the second signaling can indicate the index of the first sub-time unit by a bit value. For instance, if the second signaling indicates bit 0010, then the index of the first sub-time unit is 3.

[0368] Of course, the second signaling may also indicate the index of the first sub-time unit and / or the index of the second sub-time unit in other ways, which is not limited in this disclosure.

[0369] For example, terminal 101 may also determine the index of the first sub-time unit and / or the index of the second sub-time unit based on a predefined method. For instance, the protocol stipulates that the index of the first sub-time unit is 3 and / or the index of the second sub-time unit is 10.

[0370] Accordingly, terminal 101 can determine the time domain resources occupied by the first sub-band within the first time window based on the first sub-time unit and the second sub-time unit.

[0371] For example, terminal 101 can determine that the temporal resources occupied by the first sub-band within the first time window include:

[0372] One or more consecutive sub-time units from the beginning of the first sub-time unit to the end of the second sub-time unit.

[0373] For example, the first time unit and the second time unit are based on time slots. The first time unit is time slot #1, the second time unit is time slot #2, the first sub-time unit is symbol #3, and the second sub-time unit is symbol #10. Then, the time domain resources occupied by the first sub-band within the first time window include 23 symbols, starting from symbol #3 of time slot #1 and ending at symbol #10 of time slot #2.

[0374] It is understandable that a time unit can include N sub-time units, where N can be a positive integer.

[0375] For example, N can satisfy at least one of the following:

[0376] Divisible by M; divisible by M;

[0377] Divisible by Q.

[0378] Where M can be a positive integer.

[0379] In one example, M can be the number of symbols in a time slot, for example, M = 14.

[0380] In one example, M may also be other positive integers, which are not limited in this disclosure.

[0381] In one example, when the time unit of this disclosure includes N sub-time units, N is divisible by Q, where Q is the number of time units or sub-time units included in the first time window.

[0382] The above is merely an illustrative example, and this disclosure does not limit the specific method for determining the value of N.

[0383] Method 4: Terminal 101 determines the time domain resources occupied by the first sub-band within the first time window based on the first signaling. The first signaling indicates the second SLIV.

[0384] In one example, the time unit of this disclosure may be in the form of a symbol, a sub-slot, etc.

[0385] In one example, terminal 101 determines a second index and a fourth number based on a second SLIV indicated by a first signaling, wherein the second index is the index of the starting sub-time unit of the first sub-band within the first time window, and the fourth number is the number of sub-time units occupied by the first sub-band within the first time window.

[0386] At this point, the second index and the fourth number can be determined based on formulas 3 and 4. Furthermore, the temporal resources occupied by the first sub-band within the first time window are determined based on the second index and the fourth number. Specifically, the temporal resources occupied by the first sub-band within the first time window include:

[0387] Starting from the first sub-time unit corresponding to the second index, the fourth number of consecutive sub-time units.

[0388] For example, based on the second SLIV indicated by the first signaling, terminal 101 determines that the second index is 3 and the fourth number is 14. The first time window includes two time slots, totaling 28 symbols, with symbol indices from 0 to 27. Terminal 101 can determine that the time domain resources occupied by the first subband within the first time window include symbol #3 from slot #0, continuing for 14 symbols, that is, the end symbol of the first subband is symbol #2 from slot #1.

[0389] Method 5: Terminal 101 determines the time-domain resources occupied by the first sub-band within the first time window based on the first signaling and a predefined method. Here, it is assumed that the first signaling indicates the first SLIV.

[0390] In one example, the time unit of this disclosure may be a frame, subframe, time slot, sub-time slot, etc.

[0391] In one example, terminal 101 determines a first index and a third number based on the first SLIV indicated by the first signaling, determines the time unit corresponding to the first index as the first time unit, and determines a second time unit based on the first time unit and the third number.

[0392] For example, based on the first SLIV, the first index is determined to be 0, the third number is 2, and the time unit is in time slots. The starting time unit (first time unit) of the first sub-band within the first time window is slot#0, and the ending time unit (second time unit) of the first sub-band within the first time window is slot#1.

[0393] Furthermore, terminal 101 can determine the first sub-time unit and the second sub-time unit based on the second signaling or based on a predefined method. The determination method is similar to the method for determining the first sub-time unit and the second sub-time unit in method 3 above, and will not be described again here.

[0394] The temporal resources occupied by the first sub-band within the first time window include:

[0395] One or more consecutive sub-time units from the beginning of the first sub-time unit to the end of the second sub-time unit.

[0396] For example, assuming the first time unit is slot #0, the first sub-time unit is symbol #1, the second time unit is slot #1, and the first sub-time unit is symbol #2, then the time domain resources occupied by the first sub-band within the first time window include: 16 consecutive symbols starting from symbol #1 in slot #0 and ending at symbol #2 in slot #1.

[0397] The time unit may include N sub-time units, where N satisfies at least one of the following:

[0398] Divisible by M;

[0399] Divisible by M;

[0400] Divisible by Q.

[0401] Where M can be a positive integer. For example, M can be the number of symbols in a time slot, such as 14. Of course, M can also be any positive integer, and this disclosure does not limit this.

[0402] Where Q can be the number of time units or sub-time units included in the first time window.

[0403] The specific description of N will not be repeated here.

[0404] In step S2105, network device 102 determines the first time window.

[0405] In some embodiments, network device 102 may configure the size of the first time window based on its own implementation and send a third signaling to terminal 101, the third signaling being used to indicate the size of the first time window.

[0406] In some embodiments, network device 102 may determine the size of the first time window based on a predefined method.

[0407] In some embodiments, network device 102 may configure the size of the first time window based on a predefined method and its own implementation, and send a third signaling to terminal 101, the third signaling being used to indicate the size of the first time window.

[0408] The above is only an illustrative example. The way network device 102 determines the size of the first time window is similar to step S2102, and will not be described again here.

[0409] In some embodiments, network device 102 may configure the starting time domain position of the first time window based on its own implementation and send a fourth signaling to terminal 101, wherein the third signaling is used to indicate the starting time domain position of the first time window.

[0410] In some embodiments, network device 102 may determine the starting time domain position of the first time window based on a predefined method.

[0411] In some embodiments, network device 102 may configure the starting time domain position of the first time window based on a predefined method and its own implementation, and send a fourth signaling to terminal 101, the fourth signaling being used to indicate the starting time domain position of the first time window.

[0412] The above is only an illustrative example. The method by which network device 102 determines the starting time domain position of the first time window is similar to step S2102, and will not be repeated here.

[0413] In step S2106, network device 102 determines the time domain resources occupied by the first sub-band within the first time window.

[0414] In some embodiments, network device 102 may configure the time domain resources occupied by the first sub-band within the first time window based on its own implementation, and send a first signaling to terminal 101. The first signaling is used to indicate the time domain resources occupied by the first sub-band within the first time window.

[0415] In some embodiments, network device 102 may determine the time domain resources occupied by the first sub-band within a first time window based on a predefined method.

[0416] In some embodiments, network device 102 may configure the time domain resources occupied by the first sub-band within a first time window based on a predefined method and its own implementation, and send a first signaling to terminal 101. The first signaling is used to indicate the time domain resources occupied by the first sub-band within the first time window.

[0417] The above is merely an illustrative example. The method by which network device 102 determines the time domain resources occupied by the first sub-band within the first time window is similar to step S2104, and will not be repeated here.

[0418] In step S2107, terminal 101 sends uplink information to network device 102 on the uplink subband, or network device 102 sends downlink information to terminal 101 on the downlink subband.

[0419] In some embodiments, terminal 101 sends uplink information to network device 102 on the uplink subband based on the determined time domain resources, and network device 102 receives the uplink information on the uplink subband based on the determined time domain resources.

[0420] In some embodiments, network device 102 sends downlink information to terminal 101 on the downlink subband based on determined time domain resources, and terminal 101 receives the downlink information on the downlink subband based on determined time domain resources.

[0517] The ending OFDM time unit index is determined based on the above-mentioned starting OFDM time unit index and the number of continuous OFDM time units.

[0518] The first time window is determined based on signaling indication or a predefined method:

[0519] For example, the first time window corresponds to one TDD pattern cycle;

[0520] For example, the first time window corresponds to a TDD configuration cycle;

[0521] The following describes the specific implementation of the present invention from the perspective of the terminal:

[0522] Implementation method:

[0523] Assuming the terminal is a Rel-18 or later version terminal, and the terminal supports SBFD, the terminal is configured on the DL or flexible symbol based on the base station, and transmits uplink data on the UL subband.

[0524] As described above, the design scheme of this embodiment determines the time-domain resources corresponding to SBFD.

[0525] First, determine the first time window using the following method:

[0526] In one possible implementation, the time-domain resources corresponding to the SBFD UL subband can be indicated at the granularity of a first time window, specifying the time-domain resources corresponding to the SBFD UL subband within the first time window.

[0527] In one possible implementation, the time-domain resources corresponding to the SBFD can be periodically repeated based on a time-domain pattern determined within a first time window. For example, with the first time window corresponding to one system frame, the time-domain slot / symbol positions corresponding to the SBFD are the same in different system frames.

[0528] In one possible implementation, the first time window can be determined based on a predefined or signaling indication. For example, the first time window can be a TDD pattern cycle or a TDD configuration cycle. The TDD pattern cycle and TDD configuration cycle are described in existing solutions and will not be repeated here.

[0529] Taking the repeated transmission of the time-domain resource corresponding to the SBFD based on the time-domain pattern determined within a TDD configuration period as an example, the corresponding exemplary scenario is shown in Figure 4B.

[0530] In one possible implementation, the first time window can be determined based on a predefined method. For example, the first time window can be a system frame or a system half-frame.

[0531] In one possible implementation, the first time window comprises N time units, wherein N is determined based on signaling indication or a predefined method.

[0532] It is worth noting that the time unit corresponding to the scheme of the present invention can be one or more of the following: frame, subframe, slot, OFDM symbol, and sub-slot. The present invention does not limit this.

[0533] It is worth noting that the time unit corresponding to the scheme of the present invention may contain N OFDM symbols, and N may be determined based on signaling indication or a predefined method, without limitation.

[0534] SBFD time-domain resources within the first time window:

[0535] The following describes the specific implementation of the present invention based on the following embodiments:

[0536] Example 1 (OFDM symbol):

[0537] The terminal determines the time-domain pattern of the SBFD UL subband resource within a first time window based on indication signaling. The indication signaling is used to indicate the start time unit of the time-domain pattern and / or to indicate the end time unit of the time-domain pattern.

[0538] The time unit is an OFDM symbol, and the indication signaling is used to indicate the starting OFDM symbol index of the SBFD UL subband resource within the first time window, and the ending OFDM symbol index of the SBFD UL subband resource within the first time window.

[0539] Example 1: The start symbol index and end OFDM symbol index correspond to the OFDM symbol index of the first time window.

[0540] Taking a first time window containing 5 OFDM time slots as an example, if the indication signaling indicates that the starting OFDM symbol index = 4 and the ending OFDM symbol index = 16, the terminal determines that the SBFD UL subband time domain resource starts from the 5th corresponding symbol in the first slot and continues until the 3rd symbol in the second slot. If the index starts at 0, and if it starts at 1, it corresponds to the 4th symbol.

[0541] The indication signaling can be based on a bitmap or on an information field to indicate the corresponding index. For example, '10000' indicates the corresponding index 16.

[0542] Example 2: The starting symbol index corresponds to the OFDM symbol index of the first time window, and the ending symbol index is determined based on the number of interval symbols N between the end position of the first time window and the end position.

[0543] Taking a first time window containing 5 OFDM slots as an example, if the indication signaling indicates that the starting OFDM symbol index = 4 and the interval symbol number N = 4, the terminal determines that the SBFD UL subband time domain resource starts from the 5th corresponding symbol in the first slot and continues until the 10th symbol in the last slot. If the index starts at 0, or if it starts at 1, it corresponds to the 4th symbol.

[0544] The indication signaling can be based on a bitmap or on an information field indicating the corresponding index. For example, 7 bits indicate the corresponding OFDM symbol.

[0545] Example 2 (OFDM time slot):

[0546] The terminal determines the time-domain pattern of the SBFD UL subband resource within a first time window based on indication signaling. The indication signaling is used to indicate the start time unit of the time-domain pattern and / or to indicate the end time unit of the time-domain pattern.

[0547] The time unit is an OFDM slot, and the indication signaling is used to indicate the starting OFDM slot index of the SBFD UL subband resource within the first time window, and the ending OFDM slot index of the SBFD UL subband resource within the first time window.

[0548] Furthermore, considering that the time-domain resources of SBFD UL subband are determined based on the start and end OFDM symbols in the first time window, the terminal can also determine them based on signaling indications or predefined methods:

[0549] The starting OFDM symbol index within the starting OFDM slot index, wherein the starting OFDM symbol corresponds to the starting OFDM symbol of the SBFD UL subband within the first time window;

[0550] The end OFDM symbol index in the end OFDM slot index, wherein the end OFDM symbol corresponds to the end OFDM symbol of the SBFD UL subband in the first time window;

[0551] Example 1: The start time slot index and the end OFDM time slot index correspond to the OFDM time slot index of the first time window.

[0552] Taking a first time window containing 5 OFDM time slots as an example, if the indication signaling indicates that the starting OFDM time slot index = 1 and the ending OFDM time slot index = 4, then the terminal determines that the starting time slot corresponding to the SBFD UL subband is the 2nd time slot and the ending time slot corresponding to the SBFD UL subband is the 5th time slot.

[0553] Furthermore, if the terminal indicates, based on the signaling, that the starting OFDM symbol position in the starting OFDM slot index is 2 and the ending OFDM symbol position in the ending slot corresponding to the SBFD UL subband is 5, then the terminal determines that the SBFD UL subband time domain resource starts from the 3rd corresponding symbol in the 2nd slot and continues until the 6th symbol in the 5th slot.

[0554] Furthermore, if the indication signaling indicates that the starting OFDM symbol position in the starting OFDM slot index is 2, and the ending OFDM symbol interval in the ending slot corresponding to the SBFD UL subband is 5, then the terminal determines that the SBFD UL subband time domain resource starts from the 3rd corresponding symbol in the 2nd slot and continues until the 8th symbol in the 5th slot.

[0555] The indication signaling can be based on a bitmap or on an information field indicating the corresponding index. For example, '101' indicates the corresponding index 5.

[0556] Example 2: The starting time slot index corresponds to the OFDM time slot index of the first time window, and the ending time slot index is determined based on the number of time slots N between the end position of the first time window and the end position.

[0557] Taking a first time window containing 5 OFDM time slots as an example, if the indication signaling indicates that the starting OFDM time slot index = 1 and the number of time slots N indicating the ending position = 1, then the terminal determines that the starting time slot corresponding to the SBFD UL subband is the 2nd time slot and the ending time slot corresponding to the SBFD UL subband is the 4th time slot.

[0558] Furthermore, if the indication signaling indicates that the starting OFDM symbol position in the starting OFDM slot index is 2 and the ending OFDM symbol position in the ending slot corresponding to the SBFD UL subband is 5, then the terminal determines that the SBFD UL subband time domain resource starts from the 3rd corresponding symbol in the 2nd slot and continues until the 6th symbol in the 4th slot.

[0559] Furthermore, if the indication signaling indicates that the starting OFDM symbol position in the starting OFDM slot index is 2, and the ending OFDM symbol interval in the ending slot corresponding to the SBFD UL subband is 5, then the terminal determines that the SBFD UL subband time domain resource starts from the 3rd corresponding symbol in the 2nd slot and continues until the 8th symbol in the 4th slot.

[0560] The indication signaling can be based on a bitmap or on an information field indicating the corresponding index. For example, '101' indicates the corresponding index 5.

[0561] Example 2-1 (containing N symbols):

[0562] The terminal determines the time-domain pattern of the SBFD UL subband resource within a first time window based on indication signaling. The indication signaling is used to indicate the start time unit of the time-domain pattern and / or to indicate the end time unit of the time-domain pattern.

[0563] The time unit contains N OFDM symbols (time slots), where N is determined based on a predefined or signaling indication method.

[0564] For example, N is divisible by M, M = 14; for example, N equals 2; for example, N = 7.

[0565] For example, N is divisible by 14, M = 14; for example, N equals 14; for example, N = 28.

[0566] For example, N can be divided by Q, where Q is the number of symbols / slots contained in the first time window.

[0567] Taking a first time window containing Q=70 OFDM symbols as an example, for example, N=10, for example, N=14, for example, N=7.

[0568] The terminal determines the starting OFDM time unit index of the SBFD UL subband resource within the first time window and the ending time unit index of the SBFD UL subband resource within the first time window based on the indication signaling.

[0569] Alternatively, the starting OFDM sub-slot index of the SBFD UL subband resource within the first time window and the time interval corresponding to the ending sub-slot index of the SBFD UL subband resource within the first time window can be determined based on the indication signaling.

[0570] The proposed solution is similar to that of Embodiment 2, and will not be described in detail here.

[0571] Based on the method described in Embodiment 2, the terminal can also determine the above-mentioned starting OFDM symbol position and ending OFDM symbol position based on a predefined method.

[0572] For example, considering that the PDCCH can be transmitted in the first 3 symbols, the starting OFDM symbol in the starting OFDM time slot corresponding to the SBFD UL subband can be located after the 3rd symbol in the time slot. For example, the starting OFDM symbol index = 4.

[0573] For example, considering that SRS can be transmitted in the last 6 symbols of a time slot, the starting OFDM symbol in the starting OFDM time slot corresponding to the SBFD UL subband can be located in the last 6 symbols of the time slot. For example, the starting OFDM symbol index = 10.

[0574] For example, considering that HARQ related information can be transmitted based on the UL subband corresponding to the SBFD UL subband, the end OFDM symbol in the end OFDM time slot corresponding to the SBFD UL subband can be located in the last OFDM symbol in the time slot. For example, the end OFDM symbol index = 13.

[0575] Example 3 (slot-based SLIV):

[0576] The terminal determines the time-domain pattern of the SBFD UL subband resource within the first time window based on the indication signaling. Based on the SLIV value indicated by the indication signaling, the terminal determines the starting OFDM slot index S and the number of continuous OFDM slots L of the SBFD UL subband resource within the first time window.

[0577] Taking the total number of time slots contained in the first time window as N as an example, the corresponding relationship between the SLIV value and S and L is determined based on the following formulas 1 and 2:

[0578] if Then SLIV = N·(L-1) + S (Formula 1)

[0579] If 0 < L ≤ NS, then SLIV = N·(N-L+1) + (N-1-S) (Formula 2)

[0580] For example, the terminal determines the end OFDM slot index of the SBFD UL subband resource within the first time window based on the above S and L.

[0581] Furthermore, considering that the time-domain resources of SBFD UL subband are determined based on the start and end OFDM symbols in the first time window, the terminal can also determine them based on signaling indications or predefined methods:

[0582] The starting OFDM symbol index within the starting OFDM slot index, wherein the starting OFDM symbol corresponds to the starting OFDM symbol of the SBFD UL subband within the first time window;

[0583] The end OFDM symbol index in the end OFDM slot index, wherein the end OFDM symbol corresponds to the end OFDM symbol of the SBFD UL subband in the first time window;

[0584] The specific implementation method is similar to that of Example 2, and will not be repeated here.

[0585] Example 4 (N symbol-based SLIV):

[0586] The terminal determines the time-domain pattern of the SBFD UL subband resource within the first time window based on the indication signaling. Based on the SLIV value indicated by the indication signaling, the terminal determines the starting OFDM time unit index S and the number of continuous OFDM time units L of the SBFD UL subband resource within the first time window.

[0587] Taking the total number of sub-time units contained in the first time window as N' as an example, the corresponding relationship between the SLIV' value and S' and L' is determined based on the above formulas 3 and 4:

[0588] The time unit contains N OFDM symbols (time slots), where N is determined based on a predefined or signaling indication method.

[0589] For example, N can be divided by M; for example, M is 14 and N equals 2; for example, N = 7.

[0590] For example, N can divide M; for example, M is 14 and N equals 14; for example, N = 28.

[0591] For example, N is divisible by Q, where Q is the number of symbols / slots contained in the first time window.

[0592] Taking a first time window containing Q=70 OFDM symbols as an example, for example, N=10, for example, N=14, for example, N=7.

[0593] The terminal determines the start and end OFDM symbols of the SBFD UL subband resource in the first time window based on the indicated signaling or a predefined method. The start OFDM symbol is defined based on the start time unit, and the end OFDM symbol is defined based on the end time unit. The specific implementation is similar to Embodiment 2 and will not be repeated here.

[0594] The starting OFDM time unit index of the SBFD UL subband resource within the first time window, and the ending time unit index of the SBFD UL subband resource within the first time window.

[0595] Example 4-1:

[0596] The terminal determines the time-domain pattern of the SBFD UL subband resource within a first time window based on indication signaling. The indication signaling is used to indicate the start time unit of the time-domain pattern and / or to indicate the duration unit of the time-domain pattern.

[0597] The granularity of the time unit is determined based on a predefined or signaling indication method: for example, the time unit corresponds to an OFDM time slot; for example, the time unit corresponds to an OFDM symbol; for example, the time unit contains N OFDM symbols; the definition of the time unit can be found in Embodiment 4, and will not be repeated here.

[0598] For example, the start time unit is determined based on a bitmap or index indication method, and / or the number of duration units is determined based on a bitmap or index.

[0599] Taking the number of duration units as an example, the base station can indicate the number of units corresponding to one of L1, L2, ..., Ln based on the integer (INTEGER)(L1, L2, ..., Ln).

[0600] Taking the start time unit as an example, the base station can indicate any one of 0 to 5 corresponding to the start time unit based on INTEGER(0…5).

[0601] When the time unit corresponds to an OFDM time slot or sub-slot, the terminal can also determine the starting sub-time unit within the starting time unit based on a predefined or signaling indication method, and / or indicate the ending sub-time unit within the ending time unit. The sub-time unit can be an OFDM symbol or an OFDM sub-slot; for specific indication methods, please refer to Embodiment 2, which will not be repeated here.

[0602] As described above, the present invention mainly determines the time domain resources of the SBFD UL subband based on signaling indication or predefined methods, and can achieve flexible indication of the time domain resources while minimizing the impact of standards.

[0603] This disclosure also proposes an apparatus for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by each node (e.g., a terminal, a network device) in any of the above methods.

[0604] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
