[0019] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0020] First, the communication technologies involved in the embodiments of this application will be introduced: Subband Non-Overlapping Full Duplex (SBFD): To overcome the problems of weak uplink coverage, high uplink latency, and insufficient uplink capacity caused by limited uplink (UL) resource allocation in Time Division Duplexing (TDD) technology, SBFD technology was proposed. SBFD technology refers to the ability to simultaneously transmit and receive data on different subbands within the same subframe, time slot, or symbol. SBFD technology is primarily used on the network equipment side, while the user equipment (UE) side maintains its current state, meaning that data is only transmitted or only received within the same subframe / time slot / symbol. SBFD technology can also be called Cross Division Duplex (XDD) technology.

[0021] For example, SBFD technology such as Figure 1 As shown, a portion of the frequency domain resources corresponding to a downlink (DL) time domain unit is configured as an uplink subband. For example... Figure 1 As shown in (a), the intermediate subband of the frequency domain resource corresponding to a downlink time domain unit is configured as an uplink subband, or, as... Figure 1 As shown in (b), the upper part of the frequency domain resource corresponding to a downlink time domain unit is configured as an uplink subband.

[0022] Generally, SBFD operations satisfy the following conditions: • SBFD operation within a TDD carrier.

[0023] The SBFD scheme is designed within a single configured DL and UL BWP pair with aligned center frequencies.

[0024] Within a TDD carrier, there is a maximum of one UL subband for SBFD operation on an SBFD symbol (excluding legacy UL symbol). This uplink subband can be located in the middle of the TDD carrier or on either side of it.

[0025] This uplink subband can be configured in the TDD uplink / downlink common configuration ( TDD-UL-DL- ConfigurationCommon In the downlink symbol (DL symbol) and / or flexible symbol (FlexibleSymbol) of the signaling configuration.

[0026] For SBFD subband configuration, at least semi-static configuration is supported: For the semi-static configuration of subband time locations for SBFD operation, it is agreed that the explicit configuration of SBFD subband time locations within a period is the baseline.

[0027] For a semi-static configuration of subband frequency locations for SBFD operation, at least explicit indication of the frequency location of the UL subband is required.

[0028] TDD uplink and downlink common configuration ( TDD-UL-DL-ConfigurationCommon ): The configuration of the time slot structure can be indicated by semi-static uplink / downlink configuration signaling or dynamic uplink / downlink configuration signaling.

[0029] Among them, semi-static uplink and downlink configuration signaling includes TDD uplink and downlink common configuration ( tdd-UL-DL- ConfigurationCommon Signaling and TDD uplink / downlink dedicated configurations ( tdd-UL-DL-ConfigurationDedicated Signaling. Network devices transmit signals by sending... tdd-UL-DL-ConfigurationCommon The signaling configuration uses a common time slot structure, which is applicable to all UEs within the cell. This TDD uplink and downlink common configuration signaling can be configured as a single cycle or a dual cycle. In the case of a single cycle configuration, the cycle corresponds to one pattern, such as Pattern 1. In the case of a dual cycle configuration, the two cycles correspond to different patterns; for example, one cycle corresponds to Pattern 1, and the other cycle corresponds to Pattern 2.

[0030] In each cycle, the network device can configure the time slot structure in the pattern, with key parameters including: reference subcarrier spacing. Period P, in milliseconds (ms); number of downlink time slots Downlink symbol number Uplink time slots ; Upward sign number .

[0031] The total number of time slots S within a period can be determined based on the reference subcarrier spacing and period. The first S of these time slots... Each time slot represents a full downlink time slot, and the preceding time slot in the next time slot after the last full downlink time slot. Each symbol represents a downlink symbol. The last of the S time slots... Each time slot represents a full uplink time slot, and the last time slot in the time slot preceding the first full uplink time slot... The first symbol represents the uplink symbol. The remaining symbols in this cycle represent flexible symbols. Therefore, within a cycle, the overall frame structure is configured with downlink time slots or symbols first, uplink time slots or symbols second, and flexible time slots or symbols in between. The terminal determines the appropriate frame structure based on the following: tdd-UL-DL-ConfigurationCommon The time slot structure within a period can be determined, and the time slot structure of all time slots can be determined by repeating the period P in the time domain.

[0032] when tdd-UL-DL-ConfigurationCommon When configuring two periods, namely, configuring Pattern 1 (with period P) and Pattern 2 (with period P2) for the UE, Pattern 1 and Pattern 2 alternate in the time domain, and P+P2 is divisible by 20ms.

[0033] Information elements tdd-UL-DL-ConfigurationCommon Used to indicate the cell-specific Uplink / Downlink TDD configuration.

[0034] TDD-UL-DL-ConfigCommon information element -- ASN1START -- TAG-TDD-UL-DL-CONFIGCOMMON-START TDD-UL-DL-ConfigCommon ::= SEQUENCE { referenceSubcarrierSpacing SubcarrierSpacing, pattern1 TDD-UL-DL-Pattern, pattern2 TDD-UL-DL-PatternOPTIONAL, -- Need R ... } TDD-UL-DL-Pattern ::= SEQUENCE { dl-UL-TransmissionPeriodicity ENUMERATED {ms0p5, ms0p625,ms1, ms1p25, ms2, ms2p5, ms5, ms10}, nrofDownlinkSlots INTEGER (0..maxNrofSlots), nrofDownlinkSymbols INTEGER (0..maxNrofSymbols-1), nrofUplinkSlots INTEGER (0..maxNrofSlots), nrofUplinkSymbols INTEGER (0..maxNrofSymbols-1), ..., [[ dl-UL-TransmissionPeriodicity-v1530 ENUMERATED {ms3, ms4}OPTIONAL -- Need R ]] } -- TAG-TDD-UL-DL-CONFIGCOMMON-STOP -- ASN1STOP However, in the aforementioned transmission technologies, there is currently no feasible solution for configuring the time domain position of the uplink subband. Therefore, this application provides a method, apparatus, device, and medium for determining the time domain position, offering a specific and feasible solution for determining the time domain position of the uplink subband.

[0057] In some embodiments, step 310 can be implemented as step 410. Optionally, in addition to step 410, the method for determining the time-domain location may also include step 430, such as... Figure 4 As shown.

[0058] Figure 4The illustration shows a flowchart of a method for determining a time-domain location provided by some exemplary embodiments of this application. The method is illustrated using an example of it being executed by a UE, which can be implemented as follows: Figure 1 The terminal device 120 shown. The method includes at least some of the following steps: Step 410: Receive first configuration information, which is used to determine the time domain position of the first uplink subband; wherein the time domain position of the first uplink subband is determined according to at least one of the following: first period, first subcarrier spacing, first time domain range, reference time unit group, first time domain position information, and second time domain position information.

[0059] In some embodiments, the first configuration information includes at least one of the following: a first period, a first subcarrier spacing, a first time domain range, a reference time unit group, a first time domain location information, and a second time domain location information.

[0060] In some embodiments, the first time domain range includes all or part of the time domain units within the first period.

[0061] In some embodiments, the first configuration information is used to determine the time-domain position of the first uplink sub-band within the first cycle.

[0062] In some embodiments, the first configuration information is used to determine the time domain position of the first uplink subband within a first time domain range in the first period.

[0063] 1. Regarding the first cycle In some embodiments, the time-domain position of the first uplink subband is determined according to the first period.

[0064] In some embodiments, the time-domain location of the first uplink subband is determined based on the first period and the first subcarrier spacing.

[0065] In some embodiments, the time-domain location of the first uplink subband is determined based on the first period and the first time-domain range.

[0066] In some embodiments, the time-domain location of the first uplink subband is determined based on the first period and the reference time unit group.

[0067] In some embodiments, the time-domain position of the first uplink subband is determined based on the first period and the first time-domain position information.

[0068] In some embodiments, the time-domain position of the first uplink subband is determined based on the first period and the second time-domain position information.

[0069] In some embodiments, the first configuration information is used to determine the time-domain position of the first uplink sub-band within a first cycle. The time-domain position of the first uplink sub-band within the first cycle can be understood as the position of the time-domain unit occupied by the first uplink sub-band within the first cycle, or simply the number of time-domain units occupied by the first uplink sub-band within the first cycle. For example, the first cycle uses... express.

[0070] In some embodiments, the first cycle is related to a first operation. The first operation may be referred to as an SBFD operation, an XDD operation, etc. For details, please refer to step 310, which will not be repeated here.

[0071] In some embodiments, the first period is the period referenced by the configuration indication of the first operation.

[0072] In some embodiments, the first cycle can be understood as a cycle for SBFD configuration indication or a cycle for XDD configuration indication.

[0073] In some embodiments, the first period may be referred to as the SBFD period or the XDD period.

[0074] In some embodiments, the first cycle is agreed upon by a communication protocol or configured by first configuration information.

[0075] In this embodiment of the application, the determination of the first period includes at least the following three methods: Method 1: Determined based on the uplink and downlink transmission cycles of the first time division duplex (TDD).

[0076] In some embodiments, the first period is determined based on the first time division duplex (TDD) uplink and downlink transmission period, or the first period is determined based on the first TDD uplink and downlink transmission period and the first parameter X, where X is an integer greater than 1.

[0077] In some embodiments, the first period is the first TDD uplink / downlink transmission period, or it can be understood that the first period is the same as the first TDD uplink / downlink transmission period. In this case, the design of the first period is very simple and has the advantage of low complexity.

[0078] In some embodiments, the first period is X times the first TDD uplink / downlink transmission period. For example, such as... Figure 5As shown, taking X equal to 3 as an example, the first cycle is 3 times the first TDD uplink and downlink transmission cycle. In this case, the first cycle includes multiple first TDD uplink and downlink transmission cycles. In this case, the design of the first cycle is more flexible. By configuring the same or different number of time-domain units related to the first operation for X first TDD uplink and downlink transmission cycles, it can better adapt to different uplink transmission capacity and latency requirements in different TDD uplink and downlink transmission cycles.

[0079] The time-domain unit related to the first operation can be understood as the time-domain unit that performs uplink transmission through the first operation. It can also be understood as the time-domain unit that uses communication technology related to the first operation during uplink transmission. Alternatively, it can be understood as a time-domain unit possessing the communication characteristics of the first operation.

[0080] In some embodiments, the first TDD uplink / downlink transmission period is configured by a first signaling. In this embodiment, the first signaling is used to configure TDD uplink / downlink common parameters. Since the first signaling only configures the first TDD uplink / downlink transmission period, it can be considered that the TDD frame structure configured by the first signaling at this time is single-period.

[0081] In some embodiments, the pattern of the first TDD uplink and downlink transmission cycle is the first pattern, which can also be understood as the first signaling only configuring the first pattern.

[0082] In some embodiments, the first signaling includes t dd-UL-DL-ConfigurationCommon Signaling.

[0083] In some embodiments, X is defined by a communication protocol or configured by first configuration information.

[0084] Method 2: Determined based on the first TDD uplink / downlink transmission cycle and the second TDD uplink / downlink transmission cycle.

[0085] In some embodiments, the first period is determined based on the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period, or the first period is determined based on the first TDD uplink / downlink transmission period, the second TDD uplink / downlink transmission period, and the second parameter Y, where Y is an integer greater than 1.

[0086] In some embodiments, the first period is the sum of the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period. Alternatively, the first period can be understood as including both the first and second TDD uplink / downlink transmission periods. In this case, since the first and second TDD uplink / downlink transmission periods can differ in terms of time domain length and frame structure, they can naturally possess different uplink / downlink performance. Through flexible design of the first and second TDD uplink / downlink transmission periods, the first period can more easily adapt to different uplink transmission capacity and latency requirements, greatly improving transmission flexibility.

[0087] In some embodiments, the first period is Y times the sum of the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period. For example, as shown... Figure 6 As shown, the first TDD uplink / downlink transmission cycle is P1, and the second TDD uplink / downlink transmission cycle is P2. Taking Y = 2 as an example, the first cycle is twice the sum of the first and second TDD uplink / downlink transmission cycles, that is, the first cycle is twice P1 + P2. In this case, it supports flexible design of the first and second TDD uplink / downlink transmission cycles, making the first cycle more adaptable to latency, capacity, and reliability requirements in different communication scenarios. It also supports configuring the same or different numbers of time-domain units related to the first operation for Y first TDD uplink / downlink transmission cycles and Y second TDD uplink / downlink transmission cycles, better adapting to different uplink transmission capacity and latency requirements within different TDD uplink / downlink transmission cycles.

[0088] In some embodiments, Y is defined by a communication protocol or configured by first configuration information.

[0089] In some embodiments, the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period are configured by a first signaling. The first signaling is used to configure TDD uplink / downlink common parameters. Since the first signaling configures the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period, it can be considered that the TDD frame structure configured by the first signaling is a dual-period structure.

[0090] In some embodiments, the patterns of the first TDD uplink / downlink transmission cycle and the second TDD uplink / downlink transmission cycle are different. This can also be understood as the first signaling being configured with a first pattern and a second pattern. For example, the pattern of the first TDD uplink / downlink transmission cycle is the first pattern (e.g., Pattern 1), and the pattern of the second TDD uplink / downlink transmission cycle is the second pattern (e.g., Pattern 2).

[0091] Method 3: Determined based on the first configuration information.

[0092] In some embodiments, the first configuration information includes the configuration of a first period, which can also be understood as the first period being configured by the first configuration information. Therefore, the UE can obtain the first period based on the configuration of the first configuration information.

[0093] In some embodiments, the configuration of the first cycle includes one or more of the following: the time domain length of the first cycle, the start time domain unit of the first cycle, and the end time domain unit of the first cycle.

[0094] It should be noted that the three methods for determining the first cycle mentioned above can be used individually or in combination.

[0095] The following section introduces the relevant content regarding combined use: In some embodiments, the first configuration information configures the first period to be an integer multiple of the TDD uplink and downlink transmission period.

[0096] In some embodiments, the first configuration information configures the first period to be a first TDD uplink / downlink transmission period, or the first period to be X times the first TDD uplink / downlink transmission period. When the first signaling configures the first TDD uplink / downlink transmission period, the UE determines the first period based on the first configuration information and the first signaling. This can be considered a combination of determination method 3 and determination method 1.

[0097] In some embodiments, the first configuration information configures the first period to be the sum of the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period, or the first period to be Y times the sum of the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period. When the first signaling configures the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period, the UE determines the first period based on the first configuration information and the first signaling. This can be considered a combination of determination method 3 and determination method 2.

[0098] In some embodiments, if the first signaling does not configure any TDD uplink or downlink transmission cycle, then the UE can only use determination method 3 to determine the first cycle.

[0099] In some embodiments, the first period satisfies at least one of the following: the UE expects the first period to be divisible by 20ms; the UE expects the first period to be an integer multiple of the first TDD uplink / downlink transmission period; the UE expects the first period to be an integer multiple of the sum of the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period.

[0100] If the UE expects the first cycle to be divisible by 20ms, then the first cycle can be repeated an integer multiple of 20ms within one counting cycle of the frame structure (10240 ms) to avoid the problem of the first cycle spanning the counting cycle.

[0101] In some embodiments, the UE expects that the TDD dual-cycle and the first operation are not configured simultaneously. For example, if the first signaling configures a first TDD uplink / downlink transmission cycle and a second TDD uplink / downlink transmission cycle, the UE does not expect the first operation to be configured. The first operation may include, for example, an SBFD operation or an XDD operation. For example, if the UE is configured with the first operation, the UE does not expect the first signaling to configure a first TDD uplink / downlink transmission cycle and a second TDD uplink / downlink transmission cycle, or the UE does not expect the first signaling to configure a first pattern and a second pattern. This design simplifies UE-side behavior, simplifies transmissions related to the first operation, and especially reduces the complexity of the first cycle.

[0102] 2. Regarding the first subcarrier spacing In some embodiments, the time-domain position of the first uplink subband is determined based on the first subcarrier spacing. For example, the first subcarrier spacing is... express.

[0103] In some embodiments, the first subcarrier spacing is related to a first operation. This first operation may be referred to as an SBFD operation, an XDD operation, etc., and related details can be found in step 310, which will not be repeated here.

[0104] In some embodiments, the first subcarrier spacing is the subcarrier spacing referenced by the configuration indication of the first operation.

[0105] In some embodiments, the first subcarrier spacing can be understood as the subcarrier spacing used for SBFD configuration indication, or as the subcarrier spacing used for XDD configuration indication.

[0106] In some embodiments, the first subcarrier spacing may be referred to as the SBFD subcarrier spacing, the SBFD reference subcarrier spacing, the XDD subcarrier spacing, or the XDD reference subcarrier spacing.

[0107] In some embodiments, the first subcarrier spacing is configured by the first configuration information, or the first subcarrier spacing is agreed upon by the communication protocol.

[0108] In some embodiments, the first subcarrier spacing is less than or equal to the second subcarrier spacing. The second subcarrier spacing is configured by a first signaling, which is used to configure TDD uplink and downlink common parameters. This design, when indicating the first operation, can minimize the sharing of 1 bit of the first operation indication among multiple TDD time-domain units. This is because if the first subcarrier spacing is greater than the second subcarrier spacing, for example, if the first subcarrier spacing is 30 kHz and the second subcarrier spacing is 15 kHz, then one symbol related to the first operation corresponds to two TDD symbols. When indicating the first operation at the symbol level (per-symbol) for TDD symbols, 1 bit of the first operation indication would correspond to two TDD symbols. This situation, where multiple TDD symbols share 1 bit of the first operation indication, cannot guarantee the accuracy and precision of the first operation indication. The situation is similar when indicating the first operation at the slot level (per-slot); a first subcarrier spacing greater than the second subcarrier spacing also hinders the guarantee of accuracy and precision in indicating the first operation.

[0109] The symbols related to the first operation can be understood as symbols for uplink transmission performed through the first operation. They can also be understood as symbols for communication technologies related to the first operation used during uplink transmission. Alternatively, they can be understood as symbols possessing the communication characteristics of the first operation.

[0110] A TDD symbol can be understood as the basic unit of the first signaling configuration, or as a symbol for uplink transmission using TDD technology, or simply a symbol that employs TDD technology during uplink transmission. It can also be understood as a symbol possessing the communication characteristics of TDD technology.

[0111] For example, the first signaling includes t dd-UL-DL-ConfigurationCommon Signaling, the second subcarrier spacing is t dd-UL-DL-ConfigurationCommon The reference subcarrier spacing configured by the signaling.

[0112] In some embodiments, the first subcarrier spacing is less than or equal to the subcarrier spacing of the first bandwidth part (BWP). The first BWP includes: any uplink BWP on the first carrier, and / or, any downlink BWP on the first carrier. The first carrier is the carrier in which the first uplink subband is located. This design can minimize determination conflicts when determining the first operation for the first BWP. This is because if the first subcarrier spacing is greater than the subcarrier spacing of the first BWP, for example, if the first subcarrier spacing is 30 kHz and the first BWP subcarrier spacing is 15 kHz, assuming that the first operation is indicated at the symbol level (per-symbol) for the first BWP, that is, whether to perform the first operation is determined for each symbol corresponding to the first BWP, then one symbol corresponding to the first BWP may correspond to a 2-bit indication. However, these 2 bits of indication may conflict, for example, one bit is "1" and the other bit is "0", which cannot accurately indicate whether the first operation is performed for a symbol corresponding to the first BWP. Similarly, when indicating the first operation at the time slot level (Per-Slot) for the first BWP, if the first subcarrier spacing is greater than the subcarrier spacing of the first BWP, an indication conflict will occur, affecting the accuracy and reliability of indicating the first operation.

[0113] 3. Regarding the reference time unit group In some embodiments, the time-domain location of the first uplink subband is determined based on a reference time unit group.

[0114] In some embodiments, the reference time unit group is a reference time unit group related to the first operation. The design of the reference time unit group can also be understood as the design of the indication granularity of the first operation. The first operation can be called an SBFD operation, an XDD operation, etc., and related details can be found in step 310, which will not be repeated here.

[0115] For example, the reference time unit group uses express.

[0116] In some embodiments, the reference time unit group is the time unit group referenced by the configuration indication of the first operation. The reference time unit group may also be referred to as the time unit group.

[0117] In some embodiments, the reference time unit group can be understood as the reference time unit group of the SBFD operation, or the reference time unit group of the XDD operation, or the indication granularity of the SBFD operation, or the indication granularity of the XDD operation.

[0118] In some embodiments, the number of time-domain units within a reference time unit group is determined by the communication protocol, configured by the first configuration information, or determined by the UE.

[0119] In some embodiments, a reference time unit group includes a first number of time slots, the first number being an integer greater than or equal to 1.

[0120] In some embodiments, the first quantity is agreed upon by the communication protocol, configured by the first configuration information, or determined by the UE.

[0121] In some embodiments, the first number of time slots may be continuous or discontinuous.

[0122] In some embodiments, a reference time unit group includes a second number of sub-time slots, the second number being an integer greater than or equal to 1.

[0123] In some embodiments, the second quantity is agreed upon by the communication protocol, configured by the first configuration information, or determined by the UE.

[0124] In some embodiments, the second number of sub-time slots may be continuous or discontinuous.

[0125] In some embodiments, a reference time unit group includes a third number of symbols, the third number being an integer greater than or equal to 1.

[0126] In some embodiments, the third quantity is agreed upon by the communication protocol, configured by the first configuration information, or determined by the UE.

[0127] In some embodiments, the third number of symbols may be consecutive or discontinuous.

[0128] In some embodiments, a reference time unit group includes a fourth number of symbol groups, where the fourth number is an integer greater than or equal to 1. A symbol group includes multiple symbols, which may be consecutive or non-consecutive.

[0129] In some embodiments, the fourth quantity is agreed upon by the communication protocol, configured by the first configuration information, or determined by the UE.

[0130] In some embodiments, the fourth number of symbol groups may be continuous or discontinuous.

[0131] In some embodiments, a reference time unit group includes: G1 time slots, or G2 symbols. Wherein, G1 is an integer greater than or equal to 1, and G2 is an integer greater than or equal to 1.

[0132] In some embodiments, a reference time unit group includes one time slot. Alternatively, a reference time unit group includes one symbol. Alternatively, a reference time unit group includes one sub-time slot. Alternatively, a reference time unit group includes one symbol group. This design of single-time slot, single-symbol, single-sub-time slot, or single-symbol group indication granularity can achieve fine-grained indication, with good accuracy and flexibility, but requires a large number of bits for indication, which may burden the use of transmission resources.

[0133] In some embodiments, a reference time unit group includes multiple time slots. Alternatively, a reference time unit group includes multiple symbols. Alternatively, a reference time unit group includes multiple sub-time slots. Alternatively, a reference time unit group includes multiple symbol groups. This design of indication granularity with multiple time slots, symbols, sub-time slots, or symbol groups can reduce the number of bits required for indication and save transmission resources.

[0134] In some embodiments, when determining the time-domain location of the first uplink sub-band using a reference time unit group, one or more indication granularities are employed. This can also be understood as the time-domain location of the first uplink sub-band being determined using the same or different reference time unit groups.

[0135] In some embodiments, the time-domain location of the first uplink sub-band is determined by a reference time unit group comprising G1 time slots, i.e., the indication granularity is G1 time slots. Therefore, the first uplink sub-band occupies one or more time slots in the time domain; that is, the time-domain location of the first uplink sub-band is certain time slots. For example, the time-domain location of the first uplink sub-band is time slots N1 to N3. For example, the time-domain location of the first uplink sub-band is time slots N1, N3, and N6.

[0136] In some embodiments, the time-domain location of the first uplink subband is determined by a reference time unit group comprising G2 symbols, i.e., the indication granularity is G2 symbols. Therefore, the first uplink subband occupies one or more symbols in the time domain; that is, the time-domain location of the first uplink subband is certain symbols. For example, the time-domain location of the first uplink subband is symbols 1 to 5. For example, the time-domain location of the first uplink subband is symbols 1, 3, and 6.

[0137] In some embodiments, the time-domain location of the first uplink subband is jointly determined by a reference time unit group comprising G1 time slots and a reference time unit group comprising G2 symbols; that is, the indication granularity includes G1 time slots and G2 symbols. Thus, the first uplink subband occupies one or more time slots and one or more symbols in the time domain. This method of jointly determining the time-domain location using different indication granularities improves the determination flexibility and can meet the needs of determining various time-domain locations.

[0138] For example, such as Figure 7 As shown in (a), a reference time unit group A includes one time slot, and a reference time unit group B includes four symbols. The time domain position of the first uplink sub-band is determined by reference time unit group A and reference time unit group B as the first eight symbols in time slots N1, N2, and N3. Specifically, time slots N1 and N2 are determined by the two reference time unit groups A, and the first eight symbols in time slot N3 are determined by the two reference time unit groups B.

[0139] For example, such as Figure 7 As shown in (b), a reference time unit group A includes 2 time slots, and a reference time unit group B includes 5 symbols. The time domain position of the first uplink sub-band is determined by reference time unit groups A and B as the first symbol in time slots N1 to N3 and time slot N4. Specifically, time slots N1 and N2 are determined by one reference time unit group A, and the first symbol in time slots N3 and N4 is determined by three reference time unit groups B.

[0140] In some embodiments, the reference time unit group is agreed upon by the communication protocol, configured by the first configuration information, or determined by the UE.

[0141] In some embodiments, the reference time unit group is determined by the UE based on a first time domain range and a bitmap. For example, the reference time unit group is calculated by the UE based on the length of the first time domain range and the number of bits in the bitmap.

[0142] In some embodiments, considering that the first period may be an integer multiple of the first TDD uplink / downlink transmission period, or the first period is the sum of the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period, or the first period is an integer multiple of the sum of the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period, the indication granularity corresponding to each TDD period within the first period can be the same or different. That is, the embodiments of this application support flexible design of the indication granularity for each TDD period within the first period, greatly improving the determination flexibility and meeting the determination requirements under different communication scenarios.

[0143] In some embodiments, the reference time unit groups in each TDD cycle within the first cycle are respectively agreed upon by the communication protocol or configured by the first configuration information.

[0144] In some embodiments, the reference time unit group for a portion of the TDD cycles within the first cycle is defined by the communication protocol, while the reference time unit group for another portion of the TDD cycles is configured by the first configuration information.

[0145] For example, the first TDD uplink and downlink transmission cycle is P1, and the first cycle is three times P1. The reference time unit group in the first P1 of the first cycle includes one time slot, that is, the indication granularity in the first P1 is one time slot. The reference time unit group in the second P1 of the first cycle includes two symbols, that is, the indication granularity in the second P1 is two symbols.

[0146] For example, such as Figure 8 As shown, the first TDD uplink / downlink transmission cycle is P1, the second TDD uplink / downlink transmission cycle is P2, and the first cycle is (P1+P2)×2. Within the first cycle, the reference time unit group in the first P1 includes one time slot, meaning the indication granularity within the first P1 is one time slot. The reference time unit group in the first P2 includes two time slots, meaning the indication granularity within the first P2 is two time slots. The reference time unit group in the second P1 includes one time slot, meaning the indication granularity within the second P1 is one time slot. The reference time unit group in the second P2 includes one time slot, meaning the indication granularity within the second P2 is one time slot.

[0147] 4. Regarding the first time domain range In some embodiments, the time-domain location of the first uplink subband is determined based on a first time-domain range. For example, the first time-domain range is... express.

[0148] In some embodiments, the first configuration information is used to determine the time-domain position of the first uplink sub-band within a first time-domain range in a first period. The time-domain position of the first uplink sub-band within a first time-domain range in a first period can be understood as the position of the time-domain unit occupied by the first uplink sub-band within the first time-domain range in the first period, or it can be understood as the time-domain unit occupied by the first uplink sub-band within the first time-domain range in the first period.

[0149] In some embodiments, the first time domain range is related to the first operation. The first operation may be referred to as the SBFD operation, the XDD operation, etc. For relevant details, please refer to step 310, which will not be repeated here.

[0150] In some embodiments, the first time domain range is the time domain range indicated by the configuration of the first operation.

[0151] In some embodiments, the first time domain range is the time domain scope of the first operation. This can be understood as the first operation only operating within the first time domain range; the first operation will not be performed on time domain ranges outside the first time domain range.

[0152] In some embodiments, the first time domain range can be understood as the time domain scope of the SBFD operation; therefore, the SBFD operation will not be performed in the time domain range outside the first time domain range. The first time domain range can also be understood as the time domain scope of the XDD operation; therefore, the XDD operation will not be performed in the time domain range outside the first time domain range.

[0153] In some embodiments, the first time domain range is the time domain scope of the first configuration information. This can be understood as the first configuration information only applicable within the first time domain range, and time domain ranges outside the first time domain range not applicable to the first configuration information. Alternatively, it can be understood as the first configuration information determining the first operation within the first time domain range.

[0154] In some embodiments, the first time domain range is defined by a communication protocol, configured by first configuration information, or determined by the UE.

[0155] In some embodiments, the first time domain range is determined based on at least one of the following: uplink time slots within a first period; downlink time slots within a first period; flexible time slots within a first period; uplink symbols within a first period; downlink symbols within a first period; and flexible symbols within a first period.

[0156] In this embodiment, an uplink time slot refers to a time slot in which all symbols are used for uplink transmission. A downlink time slot refers to a time slot in which all symbols are used for downlink transmission.

[0157] In some embodiments, a flexible time slot refers to a time slot that includes flexible symbols, or a time slot in which all symbols are flexible symbols, or a time slot that includes flexible symbols but does not include uplink symbols.

[0158] In some embodiments, the first time domain range includes all time slots within the first period. This approach is simple to implement and has low complexity, but requires a large number of bits to determine the first time domain range.

[0159] In some embodiments, the first time domain range includes all remaining time slots in the first period, excluding the uplink time slots. In this case, since time slots where all symbols are used for uplink transmission have been removed, it can be ensured that all downlink symbols and flexible symbols can be indicated as the first operation, ensuring that the time domain scope of the first operation is large enough. However, this may result in some uplink symbols being determined to be within the time domain scope of the first operation, leading to errors.

[0160] In some embodiments, the first time domain range includes all remaining time slots in the first period except for the first time slot, where the first time slot is a time slot that includes an uplink symbol. In this case, it can be guaranteed that the uplink symbol will not be determined into the time domain range of the first operation. However, since a time slot will be removed as long as it includes an uplink symbol, it may be possible that some flexible time slots that include uplink symbols cannot be indicated as the first operation, which objectively reduces the time domain range of the first operation.

[0161] In some embodiments, the first time domain range includes downlink time slots within a first cycle. In this case, only time slots where all symbols are used for downlink transmission can be indicated as the first operation, which may result in some flexible time slots not being indicated as the first operation, objectively reducing the time domain scope of the first operation.

[0162] In some embodiments, the first time domain range includes downlink time slots and flexible time slots within a first cycle. If the flexible time slots do not include uplink symbols, the time domain scope of the first operation determined in this case is the most accurate. If the flexible time slots refer to time slots that include flexible symbols, it may result in some uplink symbols being determined to be within the time domain scope of the first operation, leading to errors.

[0163] In some embodiments, the first time domain range includes all symbols within the first period. This approach is simple to implement and has low complexity, but requires a large number of bits to determine the first time domain range.

[0164] In some embodiments, the first time domain range includes all symbols within the first period, excluding the uplink symbols. In this case, the time domain scope of the first operation is most precise.

[0165] In some embodiments, the first time domain range includes downlink symbols within the first cycle. This could result in certain flexible symbols not being indicated as the first operation, potentially reducing the time domain scope of the first operation.

[0166] In some embodiments, the first time domain range includes downlink symbols and flexible symbols within the first cycle. In this case, the time domain scope of the first operation is most precise.

[0167] In some embodiments, the first time domain range includes the time domain range formed from the first time slot to the last downlink time slot within the first cycle. This approach is simple to implement, but it may prevent certain flexible symbols from being indicated as the first operation, objectively reducing the time domain scope of the first operation.

[0168] In some embodiments, the first time domain range includes the time domain range formed from the first time slot to the last flexible time slot within the first cycle. If the flexible time slot does not include uplink symbols, the time domain scope of the first operation is most accurate in this case. If the flexible time slot refers to a time slot that includes flexible symbols, it may result in some uplink symbols being determined to be within the time domain scope of the first operation, leading to errors.

[0169] In some embodiments, the first time domain range includes the time domain range formed by the first symbol to the last downlink symbol within the first cycle. This is simple to implement, but it may prevent some flexible symbols from being indicated as the first operation, objectively reducing the time domain scope of the first operation.

[0170] In some embodiments, the first time domain range includes the time domain range formed from the first symbol to the last flexible symbol within the first period. In this case, the time domain scope of the first operation is most precise.

[0171] In some embodiments, the first time domain range includes the time domain range formed from the first time slot to the last downlink symbol within the first cycle.

[0172] In some embodiments, the first time domain range includes the time domain range formed from the first time slot to the last flexible symbol within the first period.

[0173] In some embodiments, the first time domain range includes the time domain range formed from the first symbol to the last downlink time slot within the first cycle.

[0174] In some embodiments, the first time domain range includes the time domain range formed from the first symbol to the last flexible time slot within the first period.

[0175] In some embodiments, the first time-domain range is determined based on a first period and / or a first subcarrier spacing. For example, the first period is... Indicates that the first subcarrier spacing is used Indicates that the first time domain range is... express.

[0176] In some embodiments, Each time slot is equivalent to the case described above where "the first time domain includes all time slots within the first period".

[0177] In some embodiments, One time slot, of which, This represents the number of uplink time slots within the first cycle. It is equivalent to the case described above where "the first time domain includes all time slots within the first cycle except for the uplink time slots".

[0178] In some embodiments, One time slot, of which, This refers to the number of first time slots within the first cycle. This is equivalent to the previously mentioned case where "the first time domain includes all remaining time slots within the first cycle, excluding the first time slot." The first time slot is the time slot that includes the uplink symbol.

[0179] In some embodiments, One time slot, of which, This refers to the number of downlink time slots within the first cycle, i.e. The number of downlink time slots in each time slot. This is equivalent to the case described above where "the first time domain range includes the downlink time slots within the first cycle".

[0180] In some embodiments, One time slot. This refers to the number of downlink time slots within the first cycle, i.e. The number of downlink time slots in each time slot. This refers to the number of flexible time slots within the first cycle, i.e. The number of flexible time slots in each time slot. This is equivalent to the case described above where "the first time domain includes the downlink time slots and flexible time slots within the first cycle".

[0181] In some embodiments, There are several symbols. Among them, This refers to the number of symbols within a time slot. For example, a time slot may contain 14 symbols, or 7 symbols, and so on. This application addresses... The value of is not restricted and can be adjusted according to the actual situation. This is equivalent to the case described above where "the first time domain range includes all symbols within the first period".

[0182] In some embodiments, There are several symbols. Among them, This represents the number of uplink symbols within the first period. It is equivalent to the case described earlier where "the first time domain includes all symbols within the first period except for the uplink symbols."

[0183] In some embodiments, There are several symbols. Among them, The number of downlink symbols in the first cycle, i.e. The number of downlink symbols in a symbol. This is equivalent to the case described above where "the first time domain range includes downlink symbols within the first period".

[0184] In some embodiments, There are several symbols. Among them, The number of downlink symbols in the first cycle, i.e. The number of downlink symbols in a symbol set. The number of flexible symbols in the first period, i.e. The number of flexible symbols in each symbol. This is equivalent to the case described above where "the first time domain range includes downlink symbols and flexible symbols within the first cycle".

[0185] In some embodiments, the first period is a first TDD uplink / downlink transmission period, and the first TDD uplink / downlink transmission period corresponds to a first pattern.

[0186] For example, taking a first subcarrier spacing of 15 kHz, a first period of 5 ms, and 14 symbols in one time slot as an example, the first time domain range under the above different determination methods is as follows: Figure 9 As shown. Therefore, the embodiments of this application support multiple optional methods for indicating or determining the first time domain range, which has excellent flexibility in indicating or determining the first time domain range, and supports providing accurate, appropriate and flexible first time domain ranges for various communication scenarios to suit different uplink transmission capacity requirements and latency requirements.

[0218] The various methods described above for indicating or determining the first and second sub-time domain ranges are flexible in design and make the first time domain range more adaptable to different uplink transmission capacity and latency requirements.

[0223] The above four methods of indicating or determining the first time domain range of "across TDD cycles" are simple to implement and require fewer bits. They do not distinguish between the first sub-time domain range and the second sub-time domain range.

[0224] For example, taking a first subcarrier spacing of 15 kHz, a first period of 5 ms, and 14 symbols in one time slot as an example, the first sub-time domain range and the second sub-time domain range under the above different determination methods are as follows: Figure 10 As shown, the time-domain position of the first uplink sub-band within the first time domain range of the first cycle includes the time-domain position of the first uplink sub-band within the first sub-time domain range of the first TDD uplink / downlink transmission cycle, and the time-domain position of the first uplink sub-band within the second sub-time domain range of the second TDD uplink / downlink transmission cycle. The first TDD uplink / downlink transmission cycle corresponds to the first pattern, and the second TDD uplink / downlink transmission cycle corresponds to the second pattern.

[0225] Therefore, the embodiments of this application support multiple optional methods for indicating or determining the first time domain range when the first period is a TDD dual period. It has excellent flexibility in indicating or determining the first time domain range and supports providing accurate, simple, and flexible first time domain ranges for various communication scenarios to suit different uplink transmission capacity requirements and latency requirements.

[0226] Case 2: The first time domain range includes integer multiples of the sub-time domain range. In some embodiments, the first period is X times the first TDD uplink and downlink transmission period, or the first period is Y times the sum of the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period.

[0227] Taking the first cycle as X times the first TDD uplink and downlink transmission cycle as an example, the first time domain range can be divided into X first sub-time domain ranges, which are represented as follows: , ... , ... , where i is an integer greater than or equal to 1 and less than or equal to X.

[0228] This represents the first sub-time domain range within the first period. This represents the range of the i-th first sub-time domain within the first period. This represents the Xth sub-time domain range within the first period.

[0229] In some embodiments, the i-th first sub-time domain range includes one of the following: all time slots within the i-th first TDD uplink / downlink transmission cycle; the remaining time slots excluding uplink time slots among all time slots within the i-th first TDD uplink / downlink transmission cycle; the remaining time slots excluding the first time slot among all time slots within the i-th first TDD uplink / downlink transmission cycle, wherein the first time slot is a time slot including uplink symbols; downlink time slots within the i-th first TDD uplink / downlink transmission cycle; downlink time slots and flexible time slots within the i-th first TDD uplink / downlink transmission cycle; all symbols within the i-th first TDD uplink / downlink transmission cycle; and all symbols within the i-th first TDD uplink / downlink transmission cycle. The remaining symbols in the symbol set excluding the uplink symbols; the downlink symbols in the i-th first TDD uplink / downlink transmission cycle; the downlink symbols and flexible symbols in the i-th first TDD uplink / downlink transmission cycle; the time domain range formed from the first time slot to the last downlink time slot in the i-th first TDD uplink / downlink transmission cycle; the time domain range formed from the first time slot to the last flexible time slot in the i-th first TDD uplink / downlink transmission cycle; the time domain range formed from the first symbol to the last downlink symbol in the i-th first TDD uplink / downlink transmission cycle; the time domain range formed from the first symbol to the last flexible symbol in the i-th first TDD uplink / downlink transmission cycle.

[0230] In some embodiments, the i-th first sub-time domain range is determined based on the i-th first TDD uplink / downlink transmission period and / or the first subcarrier spacing. The specific formula can be found in Case 1 above, and will not be repeated here.

[0231] The method of indicating or determining the first sub-time domain range as described above supports flexible design of each first sub-time domain range, making the first time domain range more adaptable to different uplink transmission capacity and latency requirements.

[0232] In some embodiments, the first TDD uplink and downlink transmission period is denoted as P1, and the first period is X times P1.

[0233] In some embodiments, the first time domain range includes the time domain range formed by the first time slot of the first P1 to the last downlink time slot of the last P1 among X P1s.

[0234] In some embodiments, the first time domain range includes the time domain range formed by the first time slot of the first P1 to the last flexible time slot of the last P1 among X P1.

[0235] In some embodiments, the first time domain range includes the time domain range formed by the first symbol of the first P1 to the last downlink symbol of the last P1 among X P1s.

[0236] In some embodiments, the first time domain range includes the time domain range formed by X P1s from the first symbol of the first P1 to the last flexible symbol of the last P1.

[0237] In some embodiments, the first time domain range includes the time domain range formed by the first time slot of the first P1 to the last downlink time slot of the i-th P1 among the X P1s.

[0238] In some embodiments, the first time domain range includes the time domain range formed by the first time slot of the first P1 to the last flexible time slot of the i-th P1 among the X P1s.

[0239] In some embodiments, the first time domain range includes the time domain range formed by the first symbol of the first P1 to the last downlink symbol of the i-th P1 among the X P1s.

[0240] In some embodiments, the first time domain range includes the time domain range formed by the first symbol of the first P1 to the last flexible symbol of the i-th P1 among X P1s.

[0241] The method of indicating or determining the first time domain range of "across TDD cycles" as described above, that is, without distinguishing between each first sub-time domain range, is a method of uniformly indicating or determining multiple first TDD uplink and downlink transmission cycles. This method is simple to implement and requires fewer bits.

[0242] For example, when the first period is X times the first TDD uplink and downlink transmission period, the first time domain range under the above different determination methods is as follows: Figure 11 As shown. Figure 11 The example shown is X = 3.

[0243] Therefore, the embodiments of this application support multiple optional methods for indicating or determining the first time domain range when the first period is an integer multiple of the TDD period. It has excellent flexibility in indicating or determining the first time domain range and supports providing accurate, simple, and flexible first time domain ranges for various communication scenarios to suit different uplink transmission capacity requirements and latency requirements.

[0244] Taking the first period as Y times the sum of the first TDD uplink and downlink transmission periods and the second TDD uplink and downlink transmission periods as an example, the first time domain range can be divided into Y sub-time domain range groups. The Y sub-time domain range groups are respectively represented as follows: , ... , ... , where i is an integer greater than or equal to 1 and less than or equal to Y.

[0245] This represents the first sub-time domain range group within the first period. This represents the i-th sub-time domain range group within the first period. This represents the Y-th sub-time domain range group within the first period.

[0246] In some embodiments, the first TDD uplink / downlink transmission period is denoted as P1, the second TDD uplink / downlink transmission period is denoted as P2, and the first period is Y times (P1+P2). Each sub-time domain range group includes a first sub-time domain range and a second sub-time domain range, wherein the first time domain range... .in, This represents the first sub-time domain range within the i-th sub-time domain range group. It represents the second sub-time domain range within the i-th sub-time domain range group.

[0247] The determination of each sub-time domain range group can refer to the content of "Case 1: The first time domain range includes the first sub-time domain range and the second sub-time domain range" in the previous text. The first sub-time domain range and the second sub-time domain range are determined by the first TDD uplink and downlink transmission cycle and the second TDD uplink and downlink transmission cycle, respectively.

[0248] The determination of the i-th sub-time domain unit group is similar to the determination of the "i-th first sub-time domain range" mentioned earlier, and will not be repeated here.

[0249] Therefore, embodiments of this application support flexible design of the first sub-time domain range and the second sub-time domain range when the first period is Y times (P1+P2), and also support flexible design of Y sub-time domain range groups, making the first time domain range more adaptable to latency requirements, capacity requirements, reliability requirements, etc. in different communication scenarios.

[0250] In some embodiments, the first time domain range includes Y ( The time domain range formed from the first time slot of the first P1 to the last downlink time slot of the last P2.

[0251] In some embodiments, the first time domain range includes Y ( The time domain range formed from the first time slot of the first P1 to the last flexible time slot of the last P2.

[0252] In some embodiments, the first time domain range includes Y ( The time domain range formed from the first symbol of the first P1 to the last downlink symbol of the last P2.

[0253] In some embodiments, the first time domain range includes Y ( The time domain range formed from the first symbol of the first P1 to the last flexible symbol of the last P2.

[0254] In some embodiments, the first time domain range includes Y ( The time domain range formed from the first time slot of the first P1 to the last downlink time slot of the i-th P2.

[0255] In some embodiments, the first time domain range includes Y ( The time domain range formed from the first time slot of the first P1 to the last flexible time slot of the i-th P2.

[0256] In some embodiments, the first time domain range includes Y ( The time domain range formed from the first symbol of the first P1 to the last downlink symbol of the i-th P2.

[0257] In some embodiments, the first time domain range includes Y ( The time domain range formed from the first symbol of the first P1 to the last flexible symbol of the i-th P2.

[0258] Therefore, the embodiments of this application support indicating or determining the first time domain range "across TDD cycles" when the first period is Y times (P1+P2), and uniformly indicating or determining multiple first TDD uplink and downlink transmission cycles and multiple second TDD uplink and downlink transmission cycles. This method is simple to implement and requires fewer bits.

[0259] For example, when the first period is Y times the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period, the first time domain range under the above different determination methods is as follows: Figure 12 As shown. Figure 12 The example shown is Y = 2.

[0260] Therefore, the embodiments of this application support multiple optional methods for indicating or determining the first time domain range when the first period is an integer multiple of the TDD double period. It has excellent flexibility in indicating or determining the first time domain range and supports providing accurate, simple, and flexible first time domain ranges for various communication scenarios to suit different uplink transmission capacity requirements and latency requirements.

[0261] 5. Regarding the first time domain location information In some embodiments, the first configuration information is used to determine the time domain position of the first uplink subband within a first time domain range in the first cycle.

[0262] In some embodiments, the time domain position of the first uplink subband is determined based on first time domain position information.

[0263] In some embodiments, the first time-domain location information includes at least one of the following: a first start indication value, used to indicate the start reference time unit group of the first uplink sub-band within the first time domain range, simply referred to as... The first length indicator value is used to indicate the number of reference time unit groups in the first uplink sub-band within the first time domain, and is simply referred to as... The first end indication value is used to indicate the end reference time unit group of the first uplink sub-band within the first time domain, and is simply referred to as... .

[0264] In some embodiments, the first time-domain location information includes and The time-domain position of the first uplink sub-band within the first time-domain range in the first cycle is based on and Sure.

[0265] In some embodiments, As stipulated by the communication protocol, Configured by the first configuration information. For example, the communication protocol agreement. First configuration information configuration Therefore, the first time domain range includes counting backwards from the agreed-upon starting reference time unit group. A group of reference time units.

[0266] In some embodiments, Configured by the first configuration information, As defined by the communication protocol. For example, the communication protocol stipulates... First configuration information configuration The first time domain range includes counting from the configured start reference time unit group onwards. A group of reference time units.

[0267] In some embodiments, and All are configured by the first configuration information.

[0268] In some embodiments, the first time-domain location information includes and The time-domain position of the first uplink sub-band within the first time-domain range in the first cycle is based on and Sure.

[0269] In some embodiments, As stipulated by the communication protocol, Configured by the first configuration information. For example, the communication protocol agreement. First configuration information configuration The first time domain range includes the period from the agreed start reference time unit group to the configured end reference time unit group.

[0270] In some embodiments, Configured by the first configuration information, As defined by the communication protocol. For example, the communication protocol stipulates... First configuration information configuration The first time domain range includes the period from the configured start reference time unit group to the agreed end reference time unit group.

[0271] In some embodiments, and All are configured by the first configuration information.

[0272] In some embodiments, the first time-domain location information includes and The time-domain position of the first uplink sub-band within the first time-domain range in the first cycle is based on and Sure.

[0273] In some embodiments, As stipulated by the communication protocol, Configured by the first configuration information. For example, the communication protocol agreement. The first configuration information is configured for the last reference time unit group, the last downlink time slot, or the last downlink symbol within the first time domain. The first time domain range includes counting backwards from the configured end reference time unit group. A group of reference time units.

[0274] In some embodiments, Configured by the first configuration information, As defined by the communication protocol. For example, the communication protocol stipulates... First configuration information configuration The first time domain range includes counting backwards from the configured end reference time unit group. A group of reference time units.

[0275] In some embodiments, and All are configured by the first configuration information.

[0276] Therefore, the method of determining the time-domain position based on one or more of the start indication value, length indication value, and end indication value can be indicated by the first configuration information. and This allows for real-time and flexible configuration of the appropriate time-domain location of the first uplink subband for the UE. It can also be agreed upon through the communication protocol. and This reduces the number of bits required for the initial configuration information, saving transmission resources.

[0277] Furthermore, the method of determining the first time domain range based on one or more of the start indication value, length indication value, and end indication value is applicable not only to cases where the first period is the first TDD uplink / downlink transmission period, but also to cases where the first period is the sum of the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period, as well as cases where the first period is an integer multiple of the first TDD uplink / downlink transmission period, and also cases where the first period is an integer multiple of the sum of the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period. In other words, when determining the first time domain range, it is not necessary to consider whether the first period can be further divided into multiple sub-periods; instead, the first period can be treated as a whole to define or configure the parameters required to determine the first time domain range.

[0278] In some embodiments, the first time-domain location information is implemented as a Start and Length Indicator Value (SLIV). The SLIV method is a method of representing the start position and length of the time-domain location through an encoded value, that is, a method of jointly encoding the start indicator value and the length indicator value to represent the time-domain location.

[0279] In some embodiments, a first SLIV is obtained by encoding a first start indication value and a first length indication value. The time-domain position of the first uplink sub-band within a first time-domain range in the first cycle can then be determined based on the first SLIV.

[0280] In some embodiments, the first SLIV is obtained according to the following encoding rules: if So the first .

[0286] In some embodiments, the reference time unit group Including a time slot or a symbol, then .

[0287] For example, such as Figure 9 In the first period shown, assuming the number of time-domain units within the first time-domain range... .

[0288] Assume a reference time unit group consists of 1 symbol, i.e. ,but That is, the first time domain includes 50 reference time unit groups.

[0289] Assume a reference time unit group consists of 2 symbols, i.e. ,but That is, the first time domain includes 25 reference time unit groups.

[0290] Assume a reference time unit group consists of 4 symbols, i.e. ,but That is, the first time domain includes 13 reference time unit groups.

[0291] When determining the time-domain location of the first uplink subband based on the first SLIV, the number of bits required for indication is small, saving transmission resources, and the first SLIV can determine several consecutive time-domain units as the time-domain location of the first uplink subband.

[0292] Furthermore, the aforementioned method of determining the first time domain range based on SLIV is applicable not only to cases where the first period is the first TDD uplink / downlink transmission period, but also to cases where the first period is the sum of the first and second TDD uplink / downlink transmission periods, as well as cases where the first period is an integer multiple of the first and second TDD uplink / downlink transmission periods. In other words, when determining the first time domain range, it is not necessary to consider whether the first period can be further divided into multiple sub-periods; instead, the first period can be treated as a whole to define or configure the parameters required to determine the first time domain range.

[0293] In some embodiments, considering that the first period is the sum of the first TDD uplink and downlink transmission periods and the second TDD uplink and downlink transmission periods, the first time domain range includes a first sub-time domain range and a second sub-time domain range. In this case, the time domain position of the first uplink sub-band within the first sub-time domain range and the time domain position within the second sub-time domain range can be determined separately, allowing for a more flexible design of the time domain position of the first uplink sub-band, making it easier to adapt to latency requirements, capacity requirements, reliability requirements, etc., under different communication scenarios.

[0319] In some embodiments, the method for determining the time-domain position of the first uplink sub-band within the first sub-time domain range may be the same as or different from the method for determining the time-domain position of the first uplink sub-band within the second sub-time domain range. For example, the time-domain position of the first uplink sub-band within the first sub-time domain range is determined by... and The time-domain position of the first uplink sub-band within the second sub-time domain is determined by the second sub-SLIV. For example, the time-domain position of the first uplink sub-band within the first sub-time domain is determined by... and It is determined that the time domain position of the first uplink sub-band within the second sub-time domain range is determined by... and Confirmed, etc. Not all possibilities are listed here, but it is understood that the embodiments of this application are not limited to using the same method to determine the time domain position of the first uplink sub-band in different sub-time domain ranges.

[0320] In some embodiments, considering that the first period is X times the first TDD uplink / downlink transmission period, the first time domain range includes X first sub-time domain ranges. In this case, the time domain position of the first uplink sub-band in each first sub-time domain range can be determined individually, making the time domain position of the first uplink sub-band more flexible and easier to adapt to latency requirements, capacity requirements, reliability requirements, etc. in different communication scenarios.

[0321] Assuming the first TDD uplink / downlink transmission cycle is denoted as P1, the first cycle includes X P1s, and the first time domain range can be divided into X first sub-time domain ranges, denoted as follows: , ... , ... , where i is an integer greater than or equal to 1 and less than or equal to X.

[0322] This represents the i-th first sub-time domain range within the first period, corresponding to the i-th P1.

[0323] In some embodiments, the first uplink subband is The time-domain location within is determined by at least one of the following: the first uplink subband is in The first uplink subband is within the reference time unit group; Number of reference time unit groups within; first uplink subband in End reference time unit group within.

[0324] The first ascending note is in The determination of the time domain position within the first sub-time domain can be referred to in the previous section on the determination of the time domain position of the first uplink sub-band within the first sub-time domain, and will not be repeated here.

[0325] In some embodiments, by applying the first uplink subband to... The start reference time unit group's indication value, the first uplink sub-band in The reference time unit group number within is encoded to obtain the i-th first sub-SLIV. The first uplink sub-band is in The temporal position within is determined based on the i-th first sub-SLIV.

[0326] The calculation principle of the i-th first sub-SLIV is similar to that of the first sub-SLIV mentioned earlier, and will not be repeated here. The total number of reference time unit groups used in the calculation process is the total number of reference time unit groups within the i-th first sub-time domain, which is determined based on the number of time domain units within the i-th first sub-time domain and the number of time domain units within the reference time unit groups.

[0327] In some embodiments, considering that the first period is Y times the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period, the first time domain range includes Y sub-time domain range groups, each sub-time domain range group including a first sub-time domain range and a second sub-time domain range. In this case, the time domain position of the first uplink sub-band within the first sub-time domain range and the second sub-time domain range can be determined separately, or the time domain position of the first uplink sub-band within each sub-time domain range group can be determined separately. This allows for a more flexible design of the time domain position of the first uplink sub-band, making it easier to adapt to latency requirements, capacity requirements, reliability requirements, etc., under different communication scenarios.

[0328] Assume the first TDD uplink / downlink transmission cycle is denoted as P1, the second TDD uplink / downlink transmission cycle is denoted as P2, the first cycle includes Y (P1+P2) cycles, and the first time domain range can be divided into Y sub-time domain range groups, denoted as follows: , ... , ... , where i is an integer greater than or equal to 1 and less than or equal to Y.

[0329] This represents the i-th sub-time domain range group within the first period, corresponding to the i-th (P1+P2).

[0330] In some embodiments, the time domain position of the first uplink sub-band within the i-th first sub-time domain is determined based on at least one of the following: the start reference time unit group of the first uplink sub-band within the i-th first sub-time domain; the number of reference time unit groups of the first uplink sub-band within the i-th first sub-time domain; and the end reference time unit group of the first uplink sub-band within the i-th first sub-time domain.

[0331] The determination of the time domain position of the first uplink sub-band within the i-th first sub-time domain range can be referred to the previous section on the determination of the time domain position of the first uplink sub-band within the first sub-time domain range, and will not be repeated here.

[0332] In some embodiments, the time domain position of the first uplink sub-band within the i-th second sub-time domain is determined based on at least one of the following: the start reference time unit group of the first uplink sub-band within the i-th second sub-time domain; the number of reference time unit groups of the first uplink sub-band within the i-th second sub-time domain; and the end reference time unit group of the first uplink sub-band within the i-th second sub-time domain.

[0333] The determination of the time domain position of the first uplink sub-band within the i-th second sub-time domain range can be referred to the previous section on the determination of the time domain position of the first uplink sub-band within the second sub-time domain range, and will not be repeated here.

[0334] In some embodiments, the i-th first sub-SLIV is obtained by encoding the indication value of the start reference time unit group of the first uplink sub-band in the i-th first sub-time domain range and the indication value of the number of reference time unit groups of the first uplink sub-band in the i-th first sub-time domain range. The time domain position of the first uplink sub-band in the i-th first sub-time domain range is determined according to the i-th first sub-SLIV.

[0335] The calculation principle of the i-th first sub-SLIV is similar to that of the first sub-SLIV described above, and will not be repeated here. The total number of reference time unit groups used in the calculation process is the total number of reference time unit groups within the i-th first sub-time domain, which is determined based on the number of time domain units within the i-th first sub-time domain and the number of time domain units within the reference time unit groups.

[0336] In some embodiments, the i-th second sub-SLIV is obtained by encoding the indication value of the start reference time unit group of the first uplink sub-band in the i-th second sub-time domain range and the indication value of the number of reference time unit groups of the first uplink sub-band in the i-th second sub-time domain range. The time domain position of the first uplink sub-band in the i-th second sub-time domain range is determined according to the i-th second sub-SLIV.

[0337] The calculation principle of the i-th second sub-SLIV is similar to that of the second sub-SLIV described above, and will not be repeated here. The total number of reference time unit groups used in the calculation process is the total number of reference time unit groups within the i-th second sub-time domain, which is determined based on the number of time domain units within the i-th second sub-time domain and the number of time domain units within the reference time unit groups.

[0338] The time domain position of the first uplink sub-band within the i-th sub-time domain range group can be determined based on the i-th first sub-SLIV and the i-th second sub-SLIV.

[0339] For example, when the first period is an integer multiple of the TDD double period, the time domain position of the first uplink sub-band determined by the above method is as follows: Figure 13 As shown. Figure 13 With Y=2, the time domain position of the first uplink sub-band in the i-th first sub-time domain range is determined according to the start reference time unit group S2 and the number of reference time unit groups L2, and the time domain position of the first uplink sub-band in the i-th second sub-time domain range is determined according to the end reference time unit group E3 and the number of reference time unit groups L3.

[0340] Therefore, embodiments of this application support multiple selectable time-domain position determination methods when the first period is a single TDD period, a double TDD period, an integer multiple of a single TDD period, or an integer multiple of a double TDD period. This provides excellent flexibility in indicating or determining the time-domain position of the first uplink sub-band, supporting accurate and flexible determination of the time-domain position of the first uplink sub-band for various communication scenarios using the first time-domain position information. In particular, it supports determining continuous time-domain positions for the first uplink sub-band with a relatively small number of bits required.

[0341] In some embodiments, if a first reference time unit group exists in the time domain location determined by the above method, and the first reference time unit group is a reference time unit group including uplink symbols, then the UE performs at least one of the following: ignoring the instruction for a first operation; ignoring the instruction for a first operation for the first reference time unit group; ignoring the instruction for a first operation for uplink symbols in the first reference time unit group; not performing the first operation in the first reference time unit group; not performing the first operation for uplink symbols in the first reference time unit group; not expecting the existence of a first reference time unit group in the time domain location determined according to the first time domain location information; expecting the absence of a first reference time unit group in the time domain location determined according to the first time domain location information.

[0342] Ignoring the instruction for the first operation can be understood as discarding the instruction upon receipt, or as not executing the first operation upon receipt.

[0343] Among them, the "unexpected" behaviors are the expectations and requirements of the UE side. The network device side will try its best not to perform behaviors that the UE side does not expect, but it is possible that the network device side will not meet the "unexpected" behaviors of the UE side.

[0344] The "expected" behavior is also the UE's expectation and requirement. The network device will try its best to execute the behavior expected by the UE, but it is possible that the network device will not meet the UE's "expected" behavior.

[0345] 6. Regarding the second time-domain location information In some embodiments, the time-domain position of the first uplink subband is determined based on the second time-domain position information.

[0346] In some embodiments, the second time-domain location information includes a first bitmap. The method of determining the time-domain location of the first uplink sub-band based on the bitmap supports both determining continuous time-domain locations for the first uplink sub-band and determining discretized time-domain locations for the first uplink sub-band, offering good flexibility.

[0347] In some embodiments, the first configuration information is used to determine the time domain position of the first uplink subband within a first time domain range in the first cycle.

[0348] In some embodiments, the time domain position of the first uplink subband within a first time domain range in the first period is determined according to a first bit map, and each reference time unit group within the first time domain range corresponds one-to-one with each bit in the first bit map.

[0349] Determining the time-domain location of the first uplink sub-band based on the bitmap includes at least the following two methods: Method 1: The number of bits in the first bit map is agreed upon by the communication protocol or configured by the first configuration information, and the number of time domain units in the reference time unit group is determined by the UE.

[0350] The number of bits in the first bitmap can also be understood as the length of the first bitmap.

[0351] In some embodiments, the number of time domain units in each reference time unit group within the first time domain range is determined by the UE based on the length of the first time domain range and the number of bits in the first bitmap.

[0352] In some embodiments, the number of time-domain units in each reference time-domain unit group within the first time-domain range is determined by the UE based on the quotient of the length of the first time-domain range and the number of bits in the first bitmap.

[0353] Taking time slots as an example, the number of time slots in each reference time unit group within the first time domain range is determined by the UE based on the quotient of the length of the first time domain range and the number of bits in the first bitmap.

[0354] Taking time-domain units as an example, the number of symbols in each reference time unit group within the first time domain range is determined by the UE based on the quotient of the length of the first time domain range and the number of bits in the first bitmap.

[0355] In some embodiments, the number of time-domain units in each reference time-domain group within the first time-domain range is the rounded-up or rounded-down result of the quotient of the length of the first time-domain range and the number of bits in the first bitmap.

[0356] For example, the communication protocol specifies that the number of bits in the first bitmap is B, or the first configuration information configures the number of bits in the first bitmap to be B. Each of the B bits corresponds one-to-one with a group of B reference time units. For example, the B bits are arranged from most significant bit to least significant bit and correspond one-to-one with the group of B reference time units.

[0357] Assuming the number of time-domain units within the first time-domain range is used The number of time-domain units within a reference time unit group is indicated by... Indicate, then or ,in," " indicates rounding up, " " indicates rounding down to the nearest integer.

[0358] In some embodiments, the number of time-domain units differs among some of the B reference time unit groups.

[0359] In some embodiments, among the B reference time unit groups, the first Each reference time unit group contains A symbol or time slot, after B- Each time unit group contains Symbol / time slot.

[0360] For example, such as Figure 9 As shown, B=20, =50 symbols The reference time unit groups corresponding to the first 10 bits arranged from most significant to least significant in the first bit map include: A symbol. B- The reference time unit groups corresponding to the last 10 bits arranged from most significant to least significant in the first bit bitmap include: A symbol.

[0361] For example, such as Figure 14 As shown, the first configuration information is set to B=12. =50 symbols , . 50-4 12=2, B- =12-50+4 12 = 10. These 12 bits are represented as B0~B11, and each of these 12 bits corresponds one-to-one with one of the 12 reference time unit groups. The first two reference time unit groups each contain 5 symbols, and the last 10 reference time unit groups each contain 4 symbols.

[0362] Method 2: The number of bits in the first bit map is determined by the UE, and the number of time domain units in the reference time unit group is agreed upon by the communication protocol or configured by the first configuration information.

[0363] The number of bits in the first bitmap can also be understood as the length of the first bitmap.

[0364] In some embodiments, the number of bits in the first bitmap is determined based on a first time domain range and a reference time unit group.

[0365] In some embodiments, the number of bits in the first bitmap is determined based on the quotient of the length of the first time domain range and the number of time domain units in the reference time unit group.

[0366] Taking a time slot as an example, the number of bits in the first bit map is determined by the UE based on the quotient of the length of the first time domain range and the number of time slots in the reference time unit group.

[0367] Taking time-domain units as an example, the number of bits in the first bit map is determined by the UE based on the quotient of the length of the first time domain range and the number of symbols in the reference time unit group.

[0368] In some embodiments, the number of bits in the first bitmap is the rounded-up or rounded-down result of the quotient of the length of the first time domain range and the number of time slots in the reference time unit group.

[0369] For example, the number of time-domain units within a reference time-domain group is determined by the communication protocol or configured by the first configuration information. Assume the number of time-domain units within the first time-domain range is denoted by . The number of bits in the first bitmap is represented by B.

[0370] ,or, ,in," " indicates rounding up.

[0371] Each of the B bits corresponds one-to-one with a B reference time unit group. For example, the B bits are arranged from the most significant bit to the least significant bit and correspond one-to-one with the B reference time unit groups.

[0372] However, there may be cases where the first time domain range cannot be equally divided into B reference time unit groups. In such cases, the number of time domain units within a portion of the reference time unit groups can be adjusted individually.

[0373] For example, such as Figure 15 As shown, the communication protocol stipulates =6 symbols, meaning the communication protocol stipulates that a reference time unit group includes 6 symbols. If =50 symbols, then Therefore, the first bitmap consists of 9 bits, denoted as B0 to B8, which correspond one-to-one with the 9 reference time unit groups from high to low. The number of symbols in the first reference time unit group is adjusted to... The number of symbols in other reference time unit groups remains the same. One symbol. Or, adjust the number of symbols in the last reference time unit group of these nine reference time unit groups to... The number of symbols in other reference time unit groups remains the same. A symbol.

[0374] For example, the first configuration information configuration =4 symbols, meaning the first configuration information configures a reference time unit group containing 4 symbols. If =50 symbols, then Therefore, the first bit map consists of 13 bits, which correspond one-to-one with the 13 reference time unit groups from the most significant bit to the least significant bit. Alternatively, adjust the number of symbols in the first reference time unit group out of these 9 reference time unit groups to 2, while keeping the number of symbols in the other reference time unit groups at 4.

[0375] The method described above for determining the first time domain range based on the bitmap is applicable to cases where the first period is the first TDD uplink / downlink transmission period, the first period is the sum of the first and second TDD uplink / downlink transmission periods, the first period is an integer multiple of the first and second TDD uplink / downlink transmission periods, and the first period is an integer multiple of the sum of the first and second TDD uplink / downlink transmission periods. In other words, when determining the first time domain range, it is not necessary to consider whether the first period can be further divided into multiple sub-periods; instead, the first period can be treated as a whole to define or configure the parameters required to determine the first time domain range.

[0376] In some embodiments, considering that the first period is the sum of the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period, the first time domain range includes a first sub-time domain range and a second sub-time domain range. In this case, the second time domain location information includes a first sub-bit map and a second sub-bit map. The time domain location of the first uplink sub-band within the first sub-time domain range can be determined based on the first sub-bit map, and the time domain location of the first uplink sub-band within the second sub-time domain range can be determined based on the second sub-bit map. By determining the location of the first uplink sub-band within the first sub-time domain range and the location within the second sub-time domain range separately using two sub-bit maps, the design of the time domain location of the first uplink sub-band becomes more flexible and easier to adapt to latency requirements, capacity requirements, reliability requirements, etc., under different communication scenarios.

[0377] In some embodiments, the first sub-bit map may be the same as or different from the second sub-bit map.

[0378] In some embodiments, the first sub-bit map and the second sub-bit map may be determined in the same or different ways.

[0379] In fact, the method for determining the time-domain position of the first uplink sub-band based on the first and second sub-bit bitmaps can refer to methods 1 and 2 described above. The difference lies in the number of time-domain units within the first sub-time domain range when calculating the first sub-bit bitmap. Replace the number of time-domain units within the first time domain range When calculating the second sub-bit map, the number of time-domain units within the second sub-time domain range is... Replace the number of time-domain units within the first time domain range This will not be elaborated upon here.

[0380] In some embodiments, considering that the first period is X times the first TDD uplink / downlink transmission period, the first time domain range includes X first sub-time domain ranges, and the time domain position of the first uplink sub-band within each of the first sub-time domain ranges can be determined based on the first sub-bit map. The X first sub-time domain ranges correspond to X first sub-bit maps respectively. In this case, the second time domain position information includes X first sub-bit maps, and the time domain position of the first uplink sub-band within each of the X sub-bit maps can be determined separately. This allows for a more flexible design of the time domain position of the first uplink sub-band, making it easier to adapt to latency requirements, capacity requirements, reliability requirements, etc., under different communication scenarios.

[0381] The determination of the i-th first sub-bit map in the X first sub-bit map is similar to the method described above. The difference is that when calculating the i-th first sub-bit map, the number of time-domain units in the i-th first time-domain range is replaced with the number of time-domain units in the first time-domain range, which will not be elaborated here.

[0382] In some embodiments, considering that the first period is Y times the first TDD uplink / downlink transmission period and the second TDD uplink / downlink transmission period, the first time domain range includes Y sub-time domain range groups. Each sub-time domain range group includes a first sub-time domain range and a second sub-time domain range. The time domain position of the first uplink sub-band within the first sub-time domain range can be determined based on the first sub-bit map, and the time domain position of the first uplink sub-band within the second sub-time domain range can be determined based on the second sub-bit map. In this case, the second time domain position information includes Y sub-bit map groups, each sub-bit map group including a first sub-bit map and a second sub-bit map. The time domain position of the first uplink sub-band within the first and second sub-time domain ranges can be determined separately using the first and second sub-bit maps, or the time domain position of the first uplink sub-band within each sub-time domain range group can be determined separately using the Y sub-bit map groups. This allows for a more flexible design of the time domain position of the first uplink sub-band, making it easier to adapt to latency requirements, capacity requirements, reliability requirements, etc., under different communication scenarios.

[0383] The time-domain position of the first uplink sub-band within the i-th sub-time-domain range group can be determined based on the i-th first sub-bit bitmap and the i-th second sub-bit bitmap. When calculating the i-th first sub-bit bitmap, the number of time-domain units within the i-th first sub-time-domain range is replaced with the number of time-domain units within the first time-domain range; this will not be elaborated further here. Similarly, when calculating the i-th second sub-bit bitmap, the number of time-domain units within the i-th second sub-time-domain range is replaced with the number of time-domain units within the first time-domain range; this will not be elaborated further here.

[0384] Therefore, the embodiments of this application support multiple optional bit map determination methods when the first period is a TDD single period, the first period is a TDD double period, the first period is an integer multiple of the TDD single period, or the first period is an integer multiple of the TDD double period. It has excellent flexibility in determining or determining the time domain position of the first uplink sub-band and supports accurate and flexible determination of the time domain position of the first uplink sub-band through bit map for various communication scenarios.

[0385] In some embodiments, if a first reference time unit group exists in the time domain location determined according to the second time domain location information, and the first reference time unit group is a reference time unit group including uplink symbols, then the UE performs at least one of the following: ignoring the instruction for a first operation; ignoring the instruction for a first operation for the first reference time unit group; ignoring the instruction for a first operation for uplink symbols in the first reference time unit group; not performing the first operation in the first reference time unit group; not performing the first operation for uplink symbols in the first reference time unit group; not expecting the existence of a first reference time unit group in the time domain location determined according to the second time domain location information; expecting the absence of a first reference time unit group in the time domain location determined according to the second time domain location information.

[0386] Ignoring the instruction for the first operation can be understood as discarding the instruction upon receipt, or as not executing the first operation upon receipt.

[0387] Among them, the "unexpected" behaviors are the expectations and requirements of the UE side. The network device side will try its best not to perform behaviors that the UE side does not expect, but it is possible that the network device side will not meet the "unexpected" behaviors of the UE side.

[0388] The "expected" behavior is also the UE's expectation and requirement. The network device will try its best to execute the behavior expected by the UE, but it is possible that the network device will not meet the UE's "expected" behavior.

[0389] It should be noted that the above six aspects can be used individually or in combination freely.

[0390] For example, the time-domain position of the first uplink sub-band is determined based on a first period. Alternatively, the time-domain position of the first uplink sub-band is determined based on a first subcarrier spacing. Alternatively, the time-domain position of the first uplink sub-band is determined based on a first time-domain range. Alternatively, the time-domain position of the first uplink sub-band is determined based on a reference time unit group. Alternatively, the time-domain position of the first uplink sub-band is determined based on first time-domain position information. Alternatively, the time-domain position of the first uplink sub-band is determined based on second time-domain position information.

[0391] For example, the time-domain position of the first uplink sub-band is determined based on the first period and the first subcarrier spacing. Alternatively, the time-domain position of the first uplink sub-band is determined based on the first period and the first time-domain range. Alternatively, the time-domain position of the first uplink sub-band is determined based on the first time-domain range and a reference time unit group. Alternatively, the time-domain position of the first uplink sub-band is determined based on the first period, the first time-domain range, and the reference time unit group. Alternatively, the time-domain position of the first uplink sub-band is determined based on the first time-domain range and first time-domain position information. Alternatively, the time-domain position of the first uplink sub-band is determined based on the first period and the first time-domain position information. Alternatively, the time-domain position of the first uplink sub-band is determined based on the first time-domain range and second time-domain position information. Alternatively, the time-domain position of the first uplink sub-band is determined based on the first period and second time-domain position information, and so on. Some examples of combined uses have been introduced above; all possibilities will not be listed here.

[0392] Step 430: Perform uplink transmission in the first uplink sub-band according to the time domain position of the first uplink sub-band.

[0393] In some embodiments, the first uplink subband is the uplink subband in SBFD technology. It can also be understood as the first uplink subband in XDD technology. Alternatively, it can be understood as the first uplink subband corresponding to the time-domain unit supporting the first operation, where the first operation refers to the technology that allows simultaneous data transmission and reception on different subbands corresponding to the same time-domain unit.

[0394] In some embodiments, if a first reference time unit group exists within the time domain location of a first uplink subband determined based on the first configuration information, and the first reference time unit group is a reference time unit group including uplink symbols, then the UE performs at least one of the following: ignores the first configuration information; ignores the configuration information in the first configuration information for the first reference time unit group; ignores the configuration information in the first configuration information for the uplink symbols within the first reference time unit group; does not perform the first operation in the first reference time unit group; does not perform the first operation on the uplink symbols within the first reference time unit group.

[0395] Ignoring the first configuration information can be understood as discarding the information upon receipt. Alternatively, it can be understood as not using the configuration specified in the first configuration information upon receipt.

[0396] In some embodiments, the first reference time unit group satisfies at least one of the following: the first reference time unit group does not include the first uplink subband; the UE assumes that the first reference time unit group does not include the first uplink subband; the uplink symbols in the first reference time unit group do not include the first uplink subband; the UE assumes that the uplink symbols in the first reference time unit group do not include the first uplink subband; the UE does not expect that the first reference time unit group exists at the time domain location determined based on the first configuration information; the UE expects that the first reference time unit group does not exist at the time domain location indicated by the first configuration information.

[0397] The first reference time unit group does not include the first uplink sub-band. This can be understood as the first reference time unit group not including the time domain units corresponding to the first uplink sub-band, or as the time domain units occupied by the first uplink sub-band not being located within the first reference time unit group, or as the frequency domain resources corresponding to the first reference time unit group not including the first uplink sub-band.

[0398] In the case where the UE assumes that the first reference time unit group does not include the first uplink subband, the first reference time unit group may actually include the uplink subband or it may not actually include the uplink subband. However, regardless of whether it actually includes it or not, the UE considers that the first reference time unit group does not include the first uplink subband. The case where the UE assumes that the uplink symbols within the first reference time unit group do not include the first uplink subband is similar and will not be described again.

[0399] Among them, the "unexpected" behaviors are the expectations and requirements of the UE side. The network device side will try its best not to perform behaviors that the UE side does not expect, but it is possible that the network device side will not meet the "unexpected" behaviors of the UE side.

[0400] The "expected" behavior is also the UE's expectation and requirement. The network device will try its best to execute the behavior expected by the UE, but it is possible that the network device will not meet the UE's "expected" behavior.

Through the separate design of the above six aspects, a reliable and feasible solution is provided for determining the time-domain position of the first uplink sub-band. The advantages of each of these six aspects, when designed individually, remain when used in combination.
