[0048] 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 only used to distinguish information of the same type from each other. 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 "at the time of" or "when" or "in response to determining."

[0049] First, the communication technology involved in the embodiments of this application is introduced:

[0050] Subband Non-Overlapping Full Duplex (SBFD):

[0051] To overcome the problems of weak uplink coverage, long 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 allows data to be simultaneously transmitted and received on different subbands within the same subframe, time slot, or symbol. SBFD is primarily used on the network equipment side, while the user equipment (UE) side maintains its current state, specifically only transmitting or receiving data within the same subframe, time slot, or symbol. SBFD is also known as Cross Division Duplex (XDD) technology.

[0052] Exemplarily, the SBFD technology, as shown in Figure 1, configures a portion of the frequency domain resources corresponding to a downlink (DL) time domain unit as an uplink subband. As shown in Figure 1(a), the middle subband of the frequency domain resources corresponding to a DL time domain unit is configured as an uplink subband. Alternatively, as shown in Figure 1(b), the upper subband of the frequency domain resources corresponding to a DL time domain unit is configured as an uplink subband.

[0053] Generally speaking, SBFD operations meet the following requirements:

[0054] SBFD operation within a TDD carrier.

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

[0056] Within a TDD carrier, there is at most one UL subband for SBFD operation in an SBFD symbol (excluding legacy UL symbol) within a TDD carrier. This uplink subband can be located in the middle of the TDD carrier or on both sides of the TDD carrier.

[0057] This uplink subband may be configured in a downlink symbol (DL symbol) and / or a flexible symbol (Flexible Symbol) configured in TDD uplink and downlink common configuration (TDD-UL-DL-ConfigurationCommon) signaling.

[0058] SBFD subband configuration supports at least semi-static configuration:

[0059] For semi-static configuration of subband time locations for SBFD operation, it is agreed that explicit configuration of SBFD subband time locations within a period is the baseline.

[0060] For semi-static configuration of subband frequency locations for SBFD operation, at least explicit indication of frequency location of UL subband is required.

[0061] TDD uplink and downlink common configuration (TDD-UL-DL-ConfigurationCommon):

[0062] The configuration of the time slot structure may be indicated by semi-static uplink and downlink configuration signaling or dynamic uplink and downlink configuration signaling.

[0063] Among them, the semi-static uplink and downlink configuration signaling includes TDD uplink and downlink common configuration (tdd-UL-DL-ConfigurationCommon) signaling and TDD uplink and downlink dedicated configuration (tdd-UL-DL-ConfigurationDedicated) signaling. The network device configures a common time slot structure by sending tdd-UL-DL-ConfigurationCommon signaling, that is, a time slot structure applicable to all UEs in the cell. The TDD uplink and downlink common configuration signaling can be configured with a single cycle or a dual cycle. When a single cycle is configured, the cycle corresponds to a pattern, such as Pattern 1 (Pattern 1). When a dual cycle is configured, the patterns corresponding to the two cycles are different, for example, one cycle corresponds to Pattern 1 (Pattern 1) and the other cycle corresponds to Pattern 2 (Pattern 2).

[0064] In each cycle, the network equipment can configure the time slot structure in the pattern. The main parameters include: reference subcarrier spacing μ ref ; Period P, in milliseconds (ms); Number of downlink time slots d slots ; Number of downlink symbols d sym ; Number of uplink time slots u slots ; Uplink symbol number u sym .

[0065] The total number of time slots S included in a period can be determined based on the reference subcarrier spacing and period. slots The first d in the next time slot of the last full downlink time slot is sym The last u in the S time slots represents the downlink symbol. slots The time slots represent the full uplink time slots. The last u in the time slot before the first full uplink time slot sym symbols represent uplink symbols. The remaining symbols in the period represent flexible symbols. Therefore, within a period, the overall configured frame structure is one in which downlink slots or symbols precede uplink slots or symbols, with flexible slots or symbols in between. The terminal can determine the slot structure within a period based on tdd-UL-DL-ConfigurationCommon. Repeating this in the time domain with period P determines the slot structure for all slots.

[0066] When tdd-UL-DL-ConfigurationCommon configures two periods, that is, when Pattern 1 (corresponding period is P) and Pattern 2 (corresponding period is P2) are configured for the UE, Pattern 1 and Pattern 2 appear alternately in the time domain, and P+P2 is divisible by 20ms.

[0067] The information element tdd-UL-DL-ConfigurationCommon is used to indicate the cell-level dedicated uplink / downlink TDD configuration (The IE TDD-UL-DL-ConfigCommon determines the cell specific Uplink / Downlink TDD configuration).

[0068] TDD-UL-DL-ConfigCommon information element

[0069] However, in the above transmission technologies, there is no feasible solution for how to configure the time domain position of the uplink subband. Therefore, this application provides a method, apparatus, device and medium for determining the time domain position, providing a specific and feasible solution for determining the time domain position of the uplink subband.

[0100] 1. About the first cycle

[0101] In some embodiments, the time domain position of the first uplink subband is determined according to a first period.

[0102] In some embodiments, the time domain position of the first uplink subband is determined according to the first period and the first subcarrier spacing.

[0103] In some embodiments, the time domain position of the first uplink subband is determined according to a first period and a first time domain range.

[0104] In some embodiments, the time domain position of the first uplink subband is determined according to the first period and the reference time unit group.

[0105] In some embodiments, the time domain position of the first uplink subband is determined according to the first period and the first time domain position information.

[0106] In some embodiments, the time domain position of the first uplink subband is determined according to the first period and the second time domain position information.

[0107] In some embodiments, the first configuration information is used to determine a time domain position of a first uplink subband within a first period. The time domain position of the first uplink subband within the first period can be understood as the position of a time domain unit occupied by the first uplink subband within the first period, or can also be understood as the time domain unit occupied by the first uplink subband within the first period. Exemplarily, the first period is represented by T.

[0108] In some embodiments, the first cycle is related to a first operation, which may be referred to as an SBFD operation or an XDD operation, etc. For related details, refer to step 310 and will not be described in detail here.

[0109] In some embodiments, the first period is a period referenced by the configuration indication of the first operation.

[0110] In some embodiments, the first period may be understood as a period for SBFD configuration indication, or may be understood as a period for XDD configuration indication.

[0111] In some embodiments, the first period may be referred to as an SBFD period or an XDD period.

[0112] In some embodiments, the first period is agreed upon by a communication protocol or configured by first configuration information.

[0113] In the embodiment of the present application, the first period is determined in at least three ways:

[0114] Determination method 1: Determine according to the first time division duplexing (TDD) uplink and downlink transmission cycle.

[0115] In some embodiments, the first period is determined according to a first time division duplexing (TDD) uplink and downlink transmission period, or the first period is determined according to the first TDD uplink and downlink transmission period and a first parameter X, where X is an integer greater than 1.

[0116] In some embodiments, the first period is the first TDD uplink and downlink transmission period, which can also be understood as the first period being the same as the first TDD uplink and downlink transmission period. In this case, the design of the first period is very simple and has the advantage of low complexity.

[0117] In some embodiments, the first period is X times the first TDD uplink and downlink transmission period. Exemplarily, as shown in FIG5 , taking X equal to 3 as an example, the first period is 3 times the first TDD uplink and downlink transmission period. In this case, the first period includes multiple first TDD uplink and downlink transmission periods. In this case, the design of the first period is more flexible, and the same or different numbers of time domain units related to the first operation can be configured for the X first TDD uplink and downlink transmission periods to better adapt to different uplink transmission capacity and latency requirements in different TDD uplink and downlink transmission periods.

[0118] The time domain unit associated with the first operation can be understood as a time domain unit that performs uplink transmission through the first operation. It can also be understood as a time domain unit that uses the communication technology associated with the first operation during uplink transmission. It can also be understood as a time domain unit that has the communication characteristics of the first operation.

[0119] In some embodiments, the first TDD uplink and downlink transmission period is configured by a first signaling. In the embodiment of the present application, the first signaling is used to configure TDD uplink and downlink common parameters. Since the first signaling only configures the first TDD uplink and downlink transmission period, it can be considered that the TDD frame structure configured by the first signaling is a single period.

[0120] In some embodiments, the pattern of the first TDD uplink and downlink transmission period is the first pattern, which can also be understood as the first signaling only configuring the first pattern.

[0121] In some embodiments, the first signaling includes tdd-UL-DL-ConfigurationCommon signaling.

[0122] In some embodiments, X is agreed upon by a communication protocol or configured by first configuration information.

[0123] Determination method 2: Determine according to the first TDD uplink and downlink transmission cycle and the second TDD uplink and downlink transmission cycle.

[0124] In some embodiments, the first period is determined according to the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period, or the first period is determined according to the first TDD uplink and downlink transmission period, the second TDD uplink and downlink transmission period and the second parameter Y, where Y is an integer greater than 1.

[0125] In some embodiments, the first cycle is the sum of the first TDD uplink and downlink transmission cycle and the second TDD uplink and downlink transmission cycle, which can also be understood as the first cycle including the first TDD uplink and downlink transmission cycle and the second TDD uplink and downlink transmission cycle. In this case, since the first TDD uplink and downlink transmission cycle and the second TDD uplink and downlink transmission cycle can be different in terms of time domain length, frame structure, etc., they can naturally have different uplink and downlink performances. Through the flexible design of the first TDD uplink and downlink transmission cycle and the second TDD uplink and downlink transmission cycle, the first cycle can be more easily adapted to different uplink transmission capacity and delay requirements, thereby greatly improving transmission flexibility.

[0126] In some embodiments, 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. For example, as shown in FIG6 , the first TDD uplink and downlink transmission period is P1, and the second TDD uplink and downlink transmission period is P2. Taking Y equal to 2 as an example, the first period is twice the sum of the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period, that is, the first period is twice P1+P2. In this case, it supports flexible design of the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period, so that the first period is easier to adapt to the delay requirements, capacity requirements, reliability requirements, etc. in different communication scenarios, and it also supports configuring the same number or different number of time domain units related to the first operation for Y first TDD uplink and downlink transmission periods and Y second TDD uplink and downlink transmission periods, so as to better adapt to different uplink transmission capacity and delay requirements in different TDD uplink and downlink transmission periods.

[0127] In some embodiments, Y is agreed upon by a communication protocol or configured by first configuration information.

[0128] In some embodiments, the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period are configured by first signaling. The first signaling is used to configure TDD uplink and downlink common parameters. Because the first signaling configures the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period, it can be considered that the TDD frame structure configured by the first signaling is dual-periodic.

[0129] In some embodiments, the patterns of the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period are different, which can also be understood as that the first signaling configures the first pattern and the second pattern. Exemplarily, the pattern of the first TDD uplink and downlink transmission period is the first pattern (e.g., Pattern 1), and the pattern of the second TDD uplink and downlink transmission period is the second pattern (e.g., Pattern 2).

[0130] Determination method 3: Determine according to the first configuration information.

[0131] In some embodiments, the first configuration information includes configuration of the 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 according to the configuration of the first configuration information.

[0132] In some embodiments, the configuration of the first period includes one or more of the following: a time domain length of the first period, a start time domain unit of the first period, and an end time domain unit of the first period.

[0133] It should be noted that the above three methods for determining the first period can be used alone or in combination.

[0134] The following describes the relevant content of the combination:

[0135] In some embodiments, the first configuration information configures the first period to be an integer multiple of the TDD uplink and downlink transmission period.

[0136] In some embodiments, the first configuration information configures the first period as the first TDD uplink and downlink transmission period, or the first period is X times the first TDD uplink and downlink transmission period. When the first signaling configures the first TDD uplink and downlink transmission period, the UE determines the first period based on the first configuration information and the first signaling. This situation can be considered a combination of determination method 3 and determination method 1.

[0137] In some embodiments, the first configuration information configures the first period as the sum of the first TDD uplink and downlink transmission period and the second 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. When the first signaling configures the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period, the UE determines the first period based on the first configuration information and the first signaling. This situation can be considered as a combination of determination method 3 and determination method 2.

[0138] In some embodiments, the first signaling does not configure any TDD uplink and downlink transmission period, so the UE can only use determination method 3 alone to determine the first period.

[0139] 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 and downlink transmission period; the UE expects the first period to be an integer multiple of the sum of the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period.

[0140] If the UE expects the first cycle to be divisible by 20ms, then an integer multiple of the first cycle can be cycled within a counting cycle (10240ms) of the frame structure to avoid the problem of the first cycle crossing the counting cycle.

[0141] In some embodiments, the UE expects that the TDD dual cycle and the first operation are not configured at the same time. For example, when the first signaling configures the first TDD uplink and downlink transmission cycle and the second TDD uplink and downlink transmission cycle, the UE does not expect to configure the first operation, and the first operation includes, for example, SBFD operation, XDD operation, etc. For example, when the UE is configured with the first operation, the UE does not expect the first signaling to configure the first TDD uplink and downlink transmission cycle and the second TDD uplink and downlink transmission cycle, or the UE does not expect the first signaling to configure the first pattern and the second pattern. Such a design can simplify the UE-side behavior, simplify the transmission related to the first operation, and especially reduce the complexity of the first cycle.

[0142] 2. Regarding the first subcarrier spacing

[0143] In some embodiments, the time domain position of the first uplink subband is determined according to a first subcarrier spacing. Exemplarily, the first subcarrier spacing is represented by μ.

[0144] In some embodiments, the first subcarrier spacing is related to a first operation, which may be referred to as an SBFD operation or an XDD operation, etc. For related details, refer to step 310 and are not described in detail here.

[0145] In some embodiments, the first subcarrier spacing is a subcarrier spacing referenced by the configuration indication of the first operation.

[0146] In some embodiments, the first subcarrier spacing may be understood as a subcarrier spacing for SBFD configuration indication, or may be understood as a subcarrier spacing for XDD configuration indication.

[0147] In some embodiments, the first subcarrier spacing may be referred to as an SBFD subcarrier spacing, or as an SBFD reference subcarrier spacing, or as an XDD subcarrier spacing, or as an XDD reference subcarrier spacing.

[0148] In some embodiments, the first subcarrier spacing is configured by first configuration information, or the first subcarrier spacing is agreed upon by a communication protocol.

[0149] In some embodiments, the first subcarrier spacing is less than or equal to the second subcarrier spacing. The second subcarrier spacing is configured by the first signaling, and the first signaling is used to configure the TDD uplink and downlink common parameters. Such a design can avoid multiple TDD time domain units sharing a 1-bit indication of the first operation as much as possible when indicating the first operation. This is because if the first subcarrier spacing is greater than the second subcarrier spacing, for example, when the first subcarrier spacing is 30kHz and the second subcarrier spacing is 15kHz, then one symbol related to the first operation corresponds to two TDD symbols. When the first operation is indicated at the symbol level (Per-Symbol) for the TDD symbol, the 1-bit indication of the first operation will correspond to two TDD symbols. However, in this case where multiple TDD symbols share a 1-bit indication of the first operation, the accuracy and precision of the indication of the first operation cannot be guaranteed. The situation when indicating the first operation at the time slot level (Per-Slot) is similar. The first subcarrier spacing being greater than the second subcarrier spacing is also not conducive to ensuring the accuracy and precision of the indication of the first operation.

[0150] The symbols related to the first operation can be understood as symbols that are uplinked via the first operation, symbols that utilize the communication technology related to the first operation during uplink transmission, or symbols that possess the communication characteristics of the first operation.

[0151] A TDD symbol can be understood as a basic unit of the first signaling configuration, a symbol transmitted uplink using the TDD technology, a symbol using the TDD technology for uplink transmission, or a symbol having the communication characteristics of the TDD technology.

[0152] Exemplarily, the first signaling includes tdd-UL-DL-ConfigurationCommon signaling, and the second subcarrier spacing is the reference subcarrier spacing configured by the tdd-UL-DL-ConfigurationCommon signaling.

[0153] 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 where the first uplink subband resides. This design can minimize 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 subcarrier spacing of the first BWP is 15 kHz, assuming that the first operation is indicated per-symbol for the first BWP, that is, whether the first operation is performed is determined for each symbol corresponding to the first BWP, then each symbol corresponding to the first BWP may correspond to a two-bit indication. However, these two-bit indications may conflict, for example, if one bit is "1" and the other bit is "0," and it is impossible to 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 problem will also occur, affecting the accuracy and reliability of indicating the first operation.

[0154] 3. About the reference time unit group

[0155] In some embodiments, the time domain position of the first uplink subband is determined according to a reference time unit group.

[0156] 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 (Granularity) of the first operation. The first operation can be called an SBFD operation, an XDD operation, etc., and the relevant content can be referred to in step 310, which is not repeated here.

[0157] Exemplarily, the reference time unit group is represented by G.

[0158] In some embodiments, the reference time unit group is a time unit group referenced by the configuration instruction of the first operation. The reference time unit group may also be referred to as a time unit group.

[0159] In some embodiments, the reference time unit group can be understood as a reference time unit group for SBFD operation, or as a reference time unit group for XDD operation, or as an indication granularity for SBFD operation, or as an indication granularity for XDD operation.

[0160] In some embodiments, the number of time domain units in the reference time unit group is agreed upon by a communication protocol, configured by first configuration information, or determined by the UE.

[0161] In some embodiments, a reference time unit group includes a first number of time slots, where the first number is an integer greater than or equal to one.

[0162] In some embodiments, the first number is agreed upon by a communication protocol, configured by first configuration information, or determined by the UE.

[0163] In some embodiments, the first number of time slots are contiguous or non-contiguous.

[0164] In some embodiments, one reference time unit group includes a second number of sub-time slots, where the second number is an integer greater than or equal to 1.

[0165] In some embodiments, the second number is agreed upon by a communication protocol, or configured by the first configuration information, or determined by the UE.

[0166] In some embodiments, the second number of sub-slots are contiguous or non-contiguous.

[0167] In some embodiments, one reference time unit group includes a third number of symbols, where the third number is an integer greater than or equal to 1.

[0168] In some embodiments, the third number is agreed upon by a communication protocol, or configured by the first configuration information, or determined by the UE.

[0169] In some embodiments, the third number of symbols are consecutive or non-consecutive.

[0170] In some embodiments, one reference time unit group includes a fourth number of symbol groups, where the fourth number is an integer greater than or equal to 1. One symbol group includes a plurality of symbols, and the plurality of symbols may be continuous or discontinuous.

[0171] In some embodiments, the fourth number is agreed upon by a communication protocol, or configured by the first configuration information, or determined by the UE.

[0172] In some embodiments, the fourth number of symbol groups are consecutive or non-consecutive.

[0173] In some embodiments, a reference time unit group includes: G1 time slots, or G2 symbols, where G1 is an integer greater than or equal to 1, and G2 is an integer greater than or equal to 1.

[0174] 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 indication granularity of single time slot, single symbol, single sub-time slot, or single symbol group enables refined indication with good accuracy and flexibility. However, the number of bits required for indication is large, which may impose a burden on the use of transmission resources.

[0175] 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 multi-time slot, multi-symbol, multi-sub-time slot, or multi-symbol group indication granularity design can reduce the number of bits required for indication, saving transmission resources.

[0176] In some embodiments, when determining the time domain position of the first uplink subband by using the reference time unit group, one or more indication granularities are used. It can also be understood that the time domain position of the first uplink subband can be determined by using the same or different reference time unit groups.

[0177] In some embodiments, the time domain location of the first uplink subband 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 subband occupies one or more time slots in the time domain, i.e., the time domain location of the first uplink subband is certain time slots. Exemplarily, the time domain location of the first uplink subband is time slots N1 to N3. Exemplarily, the time domain location of the first uplink subband is time slots N1, N3, and N6.

[0178] In some embodiments, the time domain position of the first uplink subband is determined by a reference time unit group comprising G2 symbols, i.e., the indication granularity is G2 symbols. Thus, the first uplink subband occupies one or more symbols in the time domain, i.e., the time domain position of the first uplink subband is certain symbols. Exemplarily, the time domain position of the first uplink subband is symbol 1 to symbol 5. Exemplarily, the time domain position of the first uplink subband is symbol 1, symbol 3, and symbol 6.

[0179] In some embodiments, the time domain position of the first uplink subband is jointly determined using 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. Therefore, the first uplink subband occupies both one or more time slots and one or more symbols in the time domain. This method of jointly determining the time domain position using different indication granularities improves determination flexibility and can meet various time domain position determination requirements.

[0180] For example, as shown in FIG7(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 subband is determined as the first eight symbols in time slot N1, time slot N2, and time slot N3 by referring to the reference time unit group A and the reference time unit group B. Time slot N1 and time slot 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.

[0181] For example, as shown in FIG7(b), a reference time unit group A includes two time slots, and a reference time unit group B includes five symbols. The time domain position of the first uplink subband is determined as the first symbol in time slots N1 to N3 and time slot N4 by referring to the reference time unit group A and the reference time unit group B. Time slots N1 and N2 are determined by one reference time unit group A, and the first symbols in time slots N3 and N4 are determined by three reference time unit groups B.

[0182] In some embodiments, the reference time unit group is agreed upon by a communication protocol, or configured by first configuration information, or determined by the UE.

[0183] In some embodiments, the reference time unit group is determined by the UE according to the first time domain range and the bitmap. Exemplarily, the reference time unit group is calculated by the UE according to the length of the first time domain range and the number of bits in the bitmap.

[0184] In some embodiments, considering that the first period may be an integer multiple of the first TDD uplink and downlink transmission period, or the first period is the sum of the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period, or the first period is an integer multiple of the sum of the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period, then the indication granularity corresponding to each TDD period within the first period may be the same or different. In other words, the embodiment of the present application supports flexible design of the indication granularity of each TDD period within the first period, greatly improving the determination flexibility and being able to meet the determination requirements in different communication scenarios.

[0185] In some embodiments, the reference time unit groups in each TDD period in the first period are respectively agreed upon by a communication protocol or respectively configured by the first configuration information.

[0186] In some embodiments, the reference time unit group in a portion of the TDD cycle in the first cycle is agreed upon by a communication protocol, and the reference time unit group in another portion of the TDD cycle is configured by the first configuration information.

[0187] Exemplarily, the first TDD uplink and downlink transmission period is P1, the first period is three times P1, the first reference time unit group within P1 within the first period includes one time slot, that is, the indication granularity within the first P1 is one time slot. The second reference time unit group within P1 within the first period includes two symbols, that is, the indication granularity within the second P1 is two symbols.

[0188] Exemplarily, as shown in Figure 8, the first TDD uplink and downlink transmission period is P1, the second TDD uplink and downlink transmission period is P2, and the first period is (P1+P2)×2. The reference time unit group within the first P1 in the first period includes 1 time slot, that is, the indication granularity within the first P1 is 1 time slot. The reference time unit group within the first P2 includes 2 time slots, that is, the indication granularity within the first P2 is 2 time slots. The reference time unit group within the second P1 includes 1 time slot, that is, the indication granularity within the second P1 is 1 time slot. The reference time unit group within the second P2 includes 1 time slot, that is, the indication granularity within the second P2 is 1 time slot.

[0189] 4. About the first time domain

[0190] In some embodiments, the time domain position of the first uplink subband is determined according to a first time domain range.

[0191] In some embodiments, the first configuration information is used to determine a time domain position of the first uplink subband within a first time domain range in a first cycle. The time domain position of the first uplink subband within the first time domain range in the first cycle can be understood as the position of a time domain unit occupied by the first uplink subband within the first time domain range in the first cycle, or can be understood as the time domain unit occupied by the first uplink subband within the first time domain range in the first cycle.

[0192] In some embodiments, the first time domain range is related to a first operation, which may be referred to as an SBFD operation or an XDD operation, etc. For related details, refer to step 310 and will not be described in detail here.

[0193] In some embodiments, the first time domain range is a time domain range indicated by the configuration of the first operation.

[0194] In some embodiments, the first time domain range is the time domain range of the first operation. It can be understood that the first operation will only be effective within the first time domain range, and the first operation will not be performed in time domain ranges other than the first time domain range.

[0195] In some embodiments, the first time domain range can be understood as the time domain scope of the SBFD operation. Therefore, the SBFD operation is not performed in time domain ranges other than 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 is not performed in time domain ranges other than the first time domain range.

[0196] 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 being applicable only within the first time domain range and not applicable to time domain ranges outside the first time domain range. Alternatively, this can be understood as the first configuration information determining the first operation within the first time domain range.

[0197] In some embodiments, the first time domain range is agreed upon by a communication protocol, or configured by first configuration information, or determined by the UE.

[0198] In some embodiments, the first time domain range is determined based on at least one of the following: uplink time slots within the first cycle; downlink time slots within the first cycle; flexible time slots within the first cycle; uplink symbols within the first cycle; downlink symbols within the first cycle; flexible symbols within the first cycle.

[0199] In the embodiment of the present application, an uplink time slot refers to a time slot in which all symbols are used for uplink transmission, and a downlink time slot refers to a time slot in which all symbols are used for downlink transmission.

[0200] In some embodiments, a flexible time slot refers to a time slot including flexible symbols, or a time slot in which all symbols are flexible symbols, or a time slot including flexible symbols but not including uplink symbols.

[0201] In some embodiments, the first time domain range includes all time slots in the first cycle. In this case, the implementation is simple and the complexity is low, but the number of bits required to determine the first time domain range is large.

[0202] In some embodiments, the first time domain range includes the remaining time slots of all time slots in the first cycle, excluding uplink time slots. In this case, since time slots in which all symbols are used for uplink transmission have been removed, it is 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 sufficiently large. However, this may cause some uplink symbols to be determined to be within the time domain scope of the first operation, resulting in errors.

[0203] In some embodiments, the first time domain range includes all time slots in the first cycle except the first time slot, where the first time slot is the time slot that includes the uplink symbol. In this case, it is ensured that the uplink symbol will not be determined to be within the time domain scope of the first operation. However, since a time slot is removed as long as it includes an uplink symbol, some flexible time slots that include uplink symbols may not be indicated as the first operation, which may objectively reduce the time domain scope of the first operation.

[0204] In some embodiments, the first time domain range includes downlink time slots within the first cycle. In this case, only time slots in which 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.

[0205] In some embodiments, the first time domain range includes downlink time slots and flexible time slots within the first cycle. If the flexible time slots do not include uplink symbols, the time domain range of the first operation determined in this case is most accurate. If the flexible time slots are time slots that include flexible symbols, some uplink symbols may also be determined to be within the time domain range of the first operation, resulting in errors.

[0206] In some embodiments, the first time domain range includes all symbols within the first period. In this case, the implementation is simple and the complexity is low, but the number of bits required to determine the first time domain range is large.

[0207] In some embodiments, the first time domain range includes the remaining symbols of all symbols in the first period except the uplink symbols. In this case, the time domain scope of the first operation is the most accurate.

[0208] In some embodiments, the first time domain range includes downlink symbols within a first period. In this case, some flexible symbols may not be indicated as the first operation, which objectively may reduce the time domain scope of the first operation.

[0209] In some embodiments, the first time domain range includes downlink symbols and flexible symbols within the first period. In this case, the time domain scope of the first operation is the most accurate.

[0210] In some embodiments, the first time domain range includes the time domain range formed by the first time slot to the last downlink time slot in the first cycle. This case is simple to implement, but may cause some flexible symbols to fail to indicate the first operation, which objectively may reduce the time domain scope of the first operation.

[0211] In some embodiments, the first time domain range includes the time domain range 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 range of the first operation is most accurate in this case. If the flexible time slot refers to a time slot that includes flexible symbols, some uplink symbols may also be determined to be within the time domain range of the first operation, resulting in errors.

[0212] In some embodiments, the first time domain range includes the time domain range formed by the first symbol to the last downlink symbol in the first period. This is simple to implement, but may result in some flexible symbols not being indicated as the first operation, which objectively may reduce the time domain scope of the first operation.

[0213] In some embodiments, the first time domain range includes a time domain range formed by the first symbol to the last flexible symbol in the first cycle. In this case, the time domain action range of the first operation is the most accurate.

[0214] In some embodiments, the first time domain range includes a time domain range formed from the first time slot to the last downlink symbol in the first cycle.

[0215] In some embodiments, the first time domain range includes a time domain range formed from a first time slot to a last flexible symbol in the first cycle.

[0216] In some embodiments, the first time domain range includes a time domain range formed by the first symbol to the last downlink time slot in the first cycle.

[0217] In some embodiments, the first time domain range includes a time domain range formed from the first symbol to the last flexible time slot in the first cycle.

[0218] In some embodiments, the first time domain range is determined according to the first period and / or the first subcarrier spacing. Exemplarily, the first period is represented by T, the first subcarrier spacing is represented by μ, and the first time domain range is represented by M.

[0219] In some embodiments, M=T*2 μ time slots, which is equivalent to the aforementioned situation that "the first time domain range includes all time slots in the first cycle".

[0220] In some embodiments, M=T*2 μ - D1 time slots, where D1 is the number of uplink time slots in the first cycle. This is equivalent to the aforementioned situation where "the first time domain range includes the remaining time slots in all time slots in the first cycle except the uplink time slots."

[0221] In some embodiments, M=T*2 μ-D2 time slots, where D2 is the number of first time slots in the first cycle. This is equivalent to the aforementioned situation where "the first time domain range includes the remaining time slots in all time slots in the first cycle except the first time slot." The first time slot is the time slot that includes uplink symbols.

[0222] In some embodiments, M=D3 time slots, where D3 is the number of downlink time slots in the first cycle, that is, T*2 μ This is equivalent to the above-mentioned situation where "the first time domain range includes the downlink time slots in the first cycle".

[0223] In some embodiments, M=D3+D4 time slots. Where D3 is the number of downlink time slots in the first cycle, that is, T*2 μ D4 is the number of flexible time slots in the first cycle, that is, T*2 μ This is equivalent to the above-mentioned situation where "the first time domain range includes the downlink time slots and flexible time slots in the first cycle".

[0224] In some embodiments, symbols. Among them, Refers to the number of symbols in a time slot. For example, a time slot includes 14 symbols, or a time slot includes 7 symbols, etc. There is no restriction on the value of , and it can be adjusted according to the actual situation. This is equivalent to the situation described above where "the first time domain range includes all symbols in the first period".

[0225] In some embodiments, symbols. Where Q1 is the number of uplink symbols in the first period. This is equivalent to the aforementioned situation where "the first time domain range includes the remaining symbols in all symbols in the first period except the uplink symbols."

[0226] In some embodiments, M=Q2 symbols. Q2 is the number of downlink symbols in the first cycle, i.e. This is equivalent to the above-mentioned situation where "the first time domain range includes the downlink symbols in the first period".

[0227] In some embodiments, M=Q2+Q3 symbols, where Q2 is the number of downlink symbols in the first cycle, i.e., T*2 μ * Q3 is the number of flexible symbols in the first cycle, that is, This is equivalent to the above-mentioned situation where "the first time domain range includes downlink symbols and flexible symbols in the first period".

[0228] In some embodiments, the first period is a first TDD uplink and downlink transmission period, and the first TDD uplink and downlink transmission period corresponds to a first pattern.

[0229] For example, taking the first subcarrier spacing as 15 kHz, the first period as 5 ms, and the number of symbols in a time slot as 14 as an example, the first time domain range under the above different determination methods is shown in Figure 9.

[0255] In some embodiments, symbols. Among them, Refers to the number of symbols in a time slot. For example, a time slot includes 14 symbols, or a time slot includes 7 symbols, etc. There is no restriction on the value of , and it can be adjusted according to the actual situation.

[0263] The above-mentioned various ways of indicating or determining the first sub-time domain range and the second sub-time domain range respectively are flexible in design and can make the first time domain range more easily adaptable to different uplink transmission capacity and delay requirements.

[0264] In some embodiments, the first time domain range includes a time domain range formed by the first time slot in T1 to the last downlink time slot in T2.

This method is simple to implement and requires fewer bits.

[0269] Exemplarily, taking the first subcarrier spacing as 15kHz, the first period as 5ms, and the number of symbols in a time slot as 14 as an example, the first sub-time domain range and the second sub-time domain range under the above-mentioned different determination methods are shown in Figure 10. The time domain position of the first uplink subband within the first time domain range within the first period includes the time domain position of the first uplink subband within the first sub-time domain range within the first TDD uplink and downlink transmission period, and the time domain position of the first uplink subband within the second sub-time domain range within the second TDD uplink and downlink transmission period. The first TDD uplink and downlink transmission period corresponds to the first pattern, and the second TDD uplink and downlink transmission period corresponds to the second pattern.

[0270] Therefore, the embodiment of the present application supports providing multiple optional methods for indicating or determining the first time domain range when the first period is a TDD dual period, has excellent flexibility when indicating or determining the first time domain range, and supports providing an accurate, simple to implement, and flexible first time domain range for various communication scenarios to adapt to different uplink transmission capacity requirements and delay requirements.

[0271] Case 2: The first time domain range includes integer multiples of sub-time domain ranges

[0272] 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.

[0273] Taking the first period as X times of the first TDD uplink and downlink transmission period as an example, the first time domain range can be divided into X first sub-time domain ranges, which are represented by M 1,x , ...M i,x , ...M x,x , where i is an integer greater than or equal to 1 and less than or equal to X.

[0274] M 1,x Indicates the first sub-time domain range in the first cycle, M i,x Indicates the first sub-time domain range of the i-th period, M x,x Indicates the Xth first sub-time domain range in the first cycle.

[0275] In some embodiments, the i-th first sub-time domain range includes the following: all time slots within the i-th first TDD uplink and downlink transmission cycle; the remaining time slots except the uplink time slot in all time slots within the i-th first TDD uplink and downlink transmission cycle; the remaining time slots except the first time slot in all time slots within the i-th first TDD uplink and downlink transmission cycle, the first time slot being the time slot including the uplink symbol; the downlink time slot within the i-th first TDD uplink and downlink transmission cycle; the downlink time slot and flexible time slot within the i-th first TDD uplink and downlink transmission cycle; all symbols within the i-th first TDD uplink and downlink transmission cycle; all time slots within the i-th first TDD uplink and downlink transmission cycle The remaining symbols except the uplink symbols in the symbols; the downlink symbols in the i-th first TDD uplink and downlink transmission cycle; the downlink symbols and flexible symbols in the i-th first TDD uplink and downlink transmission cycle; the time domain range formed by the first time slot to the last downlink time slot in the i-th first TDD uplink and downlink transmission cycle; the time domain range formed by the first time slot to the last flexible time slot in the i-th first TDD uplink and downlink transmission cycle; the time domain range formed by the first symbol to the last downlink symbol in the i-th first TDD uplink and downlink transmission cycle; the time domain range formed by the first symbol to the last flexible symbol in the i-th first TDD uplink and downlink transmission cycle.

[0276] In some embodiments, the i-th first sub-time domain range is determined according to the i-th first TDD uplink and downlink transmission period and / or the first subcarrier spacing. The specific formula can be referred to the above case 1 and will not be repeated here.

[0277] The manner of indicating or determining the first sub-time domain range as described above supports flexible design of each first sub-time domain range, so that the first time domain range can more easily adapt to different uplink transmission capacity and delay requirements.

[0278] In some embodiments, the first TDD uplink and downlink transmission period is represented as P1, and the first period is X times of P1.

[0279] In some embodiments, the first time domain range includes a time domain range formed from the first time slot of the first P1 to the last downlink time slot of the last P1 among the X P1s.

[0280] In some embodiments, the first time domain range includes a time domain range formed from a first time slot of a first P1 to a last flexible time slot of a last P1 among the X P1s.

[0281] In some embodiments, the first time domain range includes a time domain range formed from the first symbol of the first P1 to the last downlink symbol of the last P1 among the X P1s.

[0282] In some embodiments, the first time domain range includes a time domain range formed from a first symbol of a first P1 to a last flexible symbol of a last P1 among the X P1s.

[0283] In some embodiments, the first time domain range includes a time domain range formed from the first time slot of the first P1 to the last downlink time slot of the i-th P1 among the X P1s.

[0284] In some embodiments, the first time domain range includes a time domain range formed from the first time slot of the first P1 to the last flexible time slot of the i-th P1 among the X P1s.

[0285] In some embodiments, the first time domain range includes a time domain range formed from the first symbol of the first P1 to the last downlink symbol of the i-th P1 among the X P1s.

[0286] In some embodiments, the first time domain range includes a time domain range formed from the first symbol of the first P1 to the last flexible symbol of the i-th P1 among the X P1s.

[0287] The method of indicating or determining the first time domain range "across TDD cycles" as described above, that is, the method of uniformly indicating or determining multiple first TDD uplink and downlink transmission cycles without distinguishing between the various first sub-time domain ranges, is simple to implement and requires fewer bits.

[0288] Exemplarily, 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 shown in Figure 11. Figure 11 takes X as 3 as an example for illustration.

[0289] Therefore, the embodiments of the present application support providing multiple optional methods for indicating or determining the first time domain range when the first period is an integer multiple of the TDD period, and have excellent flexibility when indicating or determining the first time domain range. It supports providing an accurate, simple to implement, and flexible first time domain range for various communication scenarios to adapt to different uplink transmission capacity requirements and delay requirements.

[0290] Taking the first period as Y times the sum of the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period 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 represented by M 1,Y , ...M i,Y , ...M Y,Y , where i is an integer greater than or equal to 1 and less than or equal to Y.

[0291] M 1,Y Indicates the first sub-time domain range group in the first cycle, M i,Y Indicates the i-th sub-time domain range group in the first cycle, M Y,Y Indicates the Yth sub-time domain range group in the first cycle.

[0292] In some embodiments, the first TDD uplink and downlink transmission period is represented as P1, the second TDD uplink and downlink transmission period is represented 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, then the first time domain range Among them, M 1,i M2,i represents the first sub-time domain range in the i-th sub-time domain range group, and M2,i represents the second sub-time domain range in the i-th sub-time domain range group.

[0293] For the determination of each sub-time domain range group, please 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, and the first sub-time domain range and the second sub-time domain range are determined by the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period respectively.

[0294] 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” described above, and will not be repeated here.

[0295] Therefore, the embodiment of the present application supports flexible design of the first sub-time domain range and the second sub-time domain range respectively when the first period is Y times (P1+P2), and also supports flexible design of Y sub-time domain range groups respectively, so that the first time domain range can more easily adapt to the delay requirements, capacity requirements, reliability requirements, etc. in different communication scenarios.

[0296] In some embodiments, the first time domain range includes a time domain range formed from the first time slot of the first P1 to the last downlink time slot of the last P2 among the Y (P1+P2).

[0297] In some embodiments, the first time domain range includes a time domain range formed from the first time slot of the first P1 to the last flexible time slot of the last P2 among the Y (P1+P2).

[0298] In some embodiments, the first time domain range includes a time domain range formed from the first symbol of the first P1 to the last downlink symbol of the last P2 in Y (P1+P2).

[0299] In some embodiments, the first time domain range includes a time domain range formed from the first symbol of the first P1 to the last flexible symbol of the last P2 among the Y (P1+P2).

[0300] In some embodiments, the first time domain range includes a time domain range formed from the first time slot of the first P1 to the last downlink time slot of the i-th P2 among the Y (P1+P2).

[0301] In some embodiments, the first time domain range includes Y (P1+P2) time domain ranges formed from the first time slot of the first P1 to the last flexible time slot of the i-th P2.

[0302] In some embodiments, the first time domain range includes a time domain range formed from the first symbol of the first P1 to the last downlink symbol of the i-th P2 in Y (P1+P2).

[0303] In some embodiments, the first time domain range includes a time domain range formed from the first symbol of the first P1 to the last flexible symbol of the i-th P2 among the Y (P1+P2).

[0304] Therefore, the embodiment of the present application supports indicating or determining the first time domain range "across TDD cycles" when the first cycle 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. The implementation is simple and requires fewer bits.

[0305] Exemplarily, when the first period is Y times the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period, the first time domain range under the above different determination methods is shown in Figure 12. Figure 12 takes Y as 2 as an example for illustration.

[0306] Therefore, the embodiments of the present application support providing multiple optional methods for indicating or determining the first time domain range when the first period is an integer multiple of the TDD dual period, and have excellent flexibility when indicating or determining the first time domain range. It supports providing an accurate, simple to implement, and flexible first time domain range for various communication scenarios to adapt to different uplink transmission capacity requirements and delay requirements.

[0307] 5. About the first time domain location information

[0308] In some embodiments, the first configuration information is used to determine a time domain position of the first uplink subband within a first time domain range in a first cycle.

[0309] In some embodiments, the time domain position of the first uplink subband is determined according to first time domain position information.

[0310] In some embodiments, the first time domain position information includes at least one of the following: a first start indication value, used to indicate the starting reference time unit group of the first uplink subband within the first time domain range, abbreviated as S1; a first length indication value, used to indicate the number of reference time unit groups of the first uplink subband within the first time domain range, abbreviated as L1; a first end indication value, used to indicate the ending reference time unit group of the first uplink subband within the first time domain range, abbreviated as E1.

[0311] In some embodiments, the first time domain position information includes S1 and L1, and the time domain position of the first uplink subband within the first time domain range in the first cycle is determined according to S1 and L1.

[0312] In some embodiments, S1 is agreed upon by the communication protocol, and L1 is configured by the first configuration information. For example, if the communication protocol agrees on S1=0 and the first configuration information configures L1, then the first time domain range includes L1 reference time unit groups counted from the agreed starting reference time unit group.

[0313] In some embodiments, S1 is configured by the first configuration information, and L1 is agreed upon by the communication protocol. For example, if the communication protocol agrees on L1 and the first configuration information configures S1, then the first time domain range includes L1 reference time unit groups counted from the configured starting reference time unit group.

[0314] In some embodiments, both S1 and L1 are configured by first configuration information.

[0316] In some embodiments, S1 is agreed upon by the communication protocol, and E1 is configured by the first configuration information. For example, if the communication protocol agrees on S1=0 and the first configuration information configures E1, then the first time domain range includes the agreed start reference time unit group to the configured end reference time unit group.

[0317] In some embodiments, S1 is configured by the first configuration information and E1 is agreed upon by the communication protocol. For example, if the communication protocol agrees on E1 and the first configuration information configures S1, then the first time domain range includes the configured start reference time unit group to the agreed end reference time unit group.

[0318] In some embodiments, both S1 and E1 are configured by the first configuration information.

[0319] In some embodiments, the first time domain position information includes L1 and E1, and the time domain position of the first uplink subband within the first time domain range in the first cycle is determined according to L1 and E1.

[0320] In some embodiments, E1 is specified by a communication protocol, and L1 is configured by first configuration information. For example, if the communication protocol specifies E1 as the last reference time unit group, the last downlink time slot, the last downlink symbol, etc. within the first time domain range, and the first configuration information configures L1, then the first time domain range includes L1 reference time unit groups counted forward from the configured end reference time unit group.

[0321] In some embodiments, E1 is configured by the first configuration information and L1 is agreed upon by the communication protocol. For example, if the communication protocol agrees on L1 and the first configuration information configures E1, then the first time domain range includes L1 reference time unit groups counted forward from the configured end reference time unit group.

[0322] In some embodiments, both E1 and L1 are configured by the first configuration information.

[0323] Therefore, by determining the time domain position based on one or more of the start indicator value, the length indicator value, and the end indicator value, L1, S1, and E1 can be indicated through the first configuration information, thereby instantly and flexibly configuring an appropriate time domain position of the first uplink subband for the UE. Furthermore, L1, S1, and E1 can be agreed upon through the communication protocol, thereby reducing the number of bits required for the first configuration information and saving transmission resources.

[0324] Moreover, the above-mentioned method of determining the first time domain range based on one or more of the start indication value, the length indication value, and the end indication value is applicable not only to the case where the first period is the first TDD uplink and downlink transmission period, but also to the case where the first period is the sum of the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period, and also to the case where the first period is an integer multiple of the first TDD uplink and downlink transmission period, and also to the case where the first period is an integer multiple of the sum of the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period. That is to say, when determining the first time domain range, it is not necessary to consider whether the first period can be divided into multiple sub-periods, but to regard the first period as a whole to agree on or configure the various parameters required to determine the first time domain range.

[0325] 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 a coded value, that is, a method of jointly encoding the start indicator value and the length indicator value to represent the time domain location.

[0326] In some embodiments, the first SLIV is obtained by encoding the first start indicator value and the first length indicator value. The time domain position of the first uplink subband within the first time domain range in the first cycle can be determined according to the first SLIV.

[0327] In some embodiments, the first SLIV is obtained according to the following encoding rules:

[0328] If (L1-1)≤N1 / 2, then the first SLIV=N1*(L1-1)+S1.

[0329] If (L1-1)>N1 / 2, then the first SLIV=N1*(N1-L1+1)+(N1-1-S1).

[0330] Wherein, N1 represents the total number of reference time unit groups within the first time domain range, which is determined according to the number M′ of time domain units within the first time domain range and the number G′ of time domain units in the reference time unit groups.

[0331] In some embodiments, in, Indicates rounding up.

[0332] In some embodiments, in, Indicates rounding up.

[0333] In some embodiments, 0 <L1≤N1-S1。

[0334] In some embodiments, the reference time unit group G includes one time slot or one symbol, then N1=M′.

[0335] For example, in the first cycle as shown in FIG9 , it is assumed that the number of time domain units within the first time domain range is

[0336] Assuming that one reference time unit group includes 1 symbol, ie, G′=1 symbol, then N1=M′=50, that is, the first time domain range includes 50 reference time unit groups.

[0337] Assuming that one reference time unit group includes 2 symbols, ie, G′=2symbol, then N1=M′ / 2=50 / 2=25, that is, the first time domain range includes 25 reference time unit groups.

[0338] Assuming that a reference time unit group includes 4 symbols, that is, G′=4symbol, then That is, the first time domain range includes 13 reference time unit groups.

[0339] When the time domain position of the first uplink subband is determined according to the first SLIV, the number of bits required for indication is relatively small, thus saving transmission resources. In addition, the first SLIV can determine several consecutive time domain units as the time domain position of the first uplink subband.

[0340] Moreover, the above-mentioned method of determining the first time domain range based on SLIV is applicable to the case where the first period is the first TDD uplink and downlink transmission period, the case where the first period is the sum of the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period, the case where the first period is an integer multiple of the first TDD uplink and downlink transmission period, and the case where the first period is an integer multiple of the sum of the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period. That is to say, when determining the first time domain range, it is not necessary to consider whether the first period can be divided into multiple sub-periods, but to regard the first period as a whole to agree on or configure the various parameters required to determine the first time domain range.

[0341] In some embodiments, considering that the first period is the sum of the first TDD uplink and downlink transmission period and the second TDD uplink and 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 time domain position of the first uplink subband within the first sub-time domain range and the time domain position within the second sub-time domain range can be determined separately, so that the time domain position of the first uplink subband has a more flexible design and is more easily adapted to the latency requirements, capacity requirements, reliability requirements, etc. in different communication scenarios.

[0342] In some embodiments, the first time domain position information includes at least one of the following: a first sub-start indicator value, used to indicate the starting reference time unit group of the first uplink subband within the first sub-time domain, abbreviated as S2; a first sub-length indicator value, used to indicate the number of reference time unit groups of the first uplink subband within the first sub-time domain, abbreviated as L2; ​​a first sub-end indicator value, used to indicate the ending reference time unit group of the first uplink subband within the first sub-time domain, abbreviated as E2; a second sub-start indicator value, used to indicate the starting reference time unit group of the first uplink subband within the second sub-time domain, abbreviated as S3; a second sub-length indicator value, used to indicate the number of reference time unit groups of the first uplink subband within the second sub-time domain, abbreviated as L3; and a second sub-end indicator value, used to indicate the ending reference time unit group of the first uplink subband within the second sub-time domain, abbreviated as E3.

[0343] In some embodiments, the time domain position of the first uplink subband within the first sub-time domain range is determined according to one or more of S2, L2, and E2.

[0344] Similar to the first time domain range, the time domain position of the first uplink subband in the first sub-time domain range may also be determined according to S2 and L2, or according to L2 and E2, or according to S2 and E2.

[0345] Similar to S1, S2 is determined by the communication protocol or configured by the first configuration information. Similar to L1, L2 is determined by the communication protocol or configured by the first configuration information. Similar to E1, E2 is determined by the communication protocol or configured by the first configuration information.

[0346] In some embodiments, the first sub-SLIV is obtained by encoding S2 and L2. The time domain position of the first uplink sub-band within the first sub-time domain range is determined according to the first sub-SLIV.

[0347] In some embodiments, the first sub-SLIV is obtained according to the following encoding rules:

[0348] If (L2-1)≤N2 / 2, then the first sub-SLIV=N2*(L2-1)+S2.

[0349] If (L2-1)>N2 / 2, then the first sub-SLIV=N2*(N2-L2+1)+(N2-1-S2).

[0350] Wherein, N2 represents the total number of reference time unit groups within the first sub-time domain range, which is determined according to the number of time domain units M1′ within the first sub-time domain range and the number of time domain units G′ in the reference time unit groups.

[0351] In some embodiments, in, Indicates rounding up.

[0352] In some embodiments, in, Indicates rounding up.

[0353] In some embodiments, 0 <L2≤N2-S2。

[0354] For example, the communication protocol stipulates that S2 is 1, M1′=50, G′=2, then L2=11, then (L2-1)≤N2 / 2. Then the first sub-SLIV=N2*(L2-1)+S2=25*10+1=251.

[0355] For example, the first configuration information configuration S2 is 3, M1′=50, G′=6, then L2=6, then (L2-1)>N2 / 2. Then the first sub-SLIV=N2*(N2-L2+1)+(N2-1-S2)=9*(9-6+1)+(9-1-3)=41.

[0356] In some embodiments, the time domain position of the first uplink subband within the second sub-time domain range may be determined according to one or more of S3, L3, and E3.

[0357] Similar to the first time domain range and the first sub-time domain range, the time domain position of the first uplink subband in the second sub-time domain range can also be determined according to S3 and L3, or according to L3 and E3, or according to S3 and E3.

[0358] Similar to S1, S3 is determined by the communication protocol or configured by the first configuration information. Similar to L1, L3 is determined by the communication protocol or configured by the first configuration information. Similar to E1, E3 is determined by the communication protocol or configured by the first configuration information.

[0359] In some embodiments, the second sub-SLIV is obtained by encoding S3 and L3. The time domain position of the first uplink sub-band within the second sub-time domain range is determined according to the second sub-SLIV.

[0360] In some embodiments, the second sub-SLIV is obtained according to the following encoding rules:

[0361] If (L3-1)≤N3 / 2, then the second sub-SLIV=N3*(L3-1)+S3.

[0362] If (L3-1)>N3 / 2, then the second sub-SLIV=N3*(N3-L3+1)+(N3-1-S3).

[0363] Wherein, N3 represents the total number of reference time unit groups within the second sub-time domain range, which is determined according to the number of time domain units M2′ within the second sub-time domain range and the number of time domain units G′ in the reference time unit group.

[0364] In some embodiments, in, Indicates rounding up.

[0365] In some embodiments, in, Indicates rounding up.

[0366] In some embodiments, 0 <L3≤N3-S3。

[0367] For example, the communication protocol stipulates that S3 is 1, M2′=60, G′=3, then L3=11, then (L3-1)≤N3 / 2. Then the second sub-SLIV=N3*(L3-1)+S3=20*10+1=201.

[0368] For example, the first configuration information configuration S3 is 3, M2′=60, G′=7, then L3=6, then (L3-1)≤N3 / 2. Then the second sub-SLIV=N3*(L3-1)+S3=61*5+3=308.

[0369] In some embodiments, the manner in which the time domain position of the first uplink subband within the first sub-time domain range is determined is the same as or different from the manner in which the time domain position of the first uplink subband within the second sub-time domain range is determined. Exemplarily, the time domain position of the first uplink subband within the first sub-time domain range is determined by L2 and E2, and the time domain position of the first uplink subband within the second sub-time domain range is determined by the second sub-SLIV. Exemplarily, the time domain position of the first uplink subband within the first sub-time domain range is determined by S2 and L2, and the time domain position of the first uplink subband within the second sub-time domain range is determined by S3 and E3, and so on. Not all possibilities are listed here, but it can be understood that the embodiments of the present application do not limit the determination of the time domain position of the first uplink subband within different sub-time domain ranges to the same manner.

[0370] In some embodiments, considering that the first period is X times the first TDD uplink and 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 separately, so that the time domain position of the first uplink sub-band has a more flexible design and is more easily adapted to the latency requirements, capacity requirements, reliability requirements, etc. in different communication scenarios.

[0371] Assume that the first TDD uplink and downlink transmission cycle is represented by P1, the first cycle includes X P1s, and the first time domain range can be divided into X first sub-time domain ranges, which are represented by M 1,x , ...M i,x , ...M x,x , where i is an integer greater than or equal to 1 and less than or equal to X.

[0372] M i,x It represents the i-th first sub-time domain range in the first period, corresponding to the i-th P1.

[0373] In some embodiments, the first uplink subband is in M i,x The time domain position within M is determined according to at least one of the following: the first uplink subband is in M i,x The first uplink subband is at M i,x The number of reference time unit groups within M i,x The ending reference time unit group within.

[0374] The first upstream subband is in M i,x For the determination of the time domain position within the first sub-time domain, reference may be made to the determination of the time domain position of the first uplink sub-band within the first sub-time domain, which will not be repeated here.

[0375] In some embodiments, by performing the first uplink sub-band i,x The indication value of the start reference time unit group within M i,x The first uplink subband is encoded with the indication value of the number of reference time unit groups in M ​​to obtain the i-th first sub-SLIV. i,x The time domain position within is determined according to the i-th first sub-SLIV.

[0376] The calculation principle for the i-th first sub-SLIV is similar to that of the first sub-SLIV described above and is not repeated here. The total number of reference time unit groups used in the calculation is the total number of reference time unit groups within the i-th first sub-time domain, 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.

[0377] In some embodiments, taking into account the situation that the first period is Y times the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period, the first time domain range includes Y sub-time domain range groups, and each sub-time domain range group 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 subband in the first sub-time domain range and the time domain position in the second sub-time domain range can be determined separately, and the time domain position of the first uplink subband in each sub-time domain range group can also be determined separately, so that the time domain position of the first uplink subband has a more flexible design and is more easily adapted to the delay requirements, capacity requirements, reliability requirements, etc. in different communication scenarios.

[0378] Assume that the first TDD uplink and downlink transmission cycle is represented by P1, the second TDD uplink and downlink transmission cycle is represented by P2, the first cycle includes Y (P1+P2), and the first time domain range can be divided into Y sub-time domain range groups, which are represented by M 1,Y , ...M i,Y , ...M Y,Y , where i is an integer greater than or equal to 1 and less than or equal to Y.

[0379] M i,Y Indicates the i-th sub-time domain range group in the first period, corresponding to the i-th (P1+P2).

[0380] In some embodiments, the time domain position of the first uplink subband within the i-th first sub-time domain range is determined based on at least one of the following: the starting reference time unit group of the first uplink subband within the i-th first sub-time domain range; the number of reference time unit groups of the first uplink subband within the i-th first sub-time domain range; and the ending reference time unit group of the first uplink subband within the i-th first sub-time domain range.

[0381] For determining the time domain position of the first uplink subband within the i-th first sub-time domain range, reference may be made to the above determination of the time domain position of the first uplink subband within the first sub-time domain range, which will not be repeated here.

[0382] In some embodiments, the time domain position of the first uplink subband within the i-th second sub-time domain range is determined based on at least one of the following: the starting reference time unit group of the first uplink subband within the i-th second sub-time domain range; the number of reference time unit groups of the first uplink subband within the i-th second sub-time domain range; and the ending reference time unit group of the first uplink subband within the i-th second sub-time domain range.

[0383] The determination of the time domain position of the first uplink subband within the i-th second sub-time domain range may refer to the determination of the time domain position of the first uplink subband within the second sub-time domain range mentioned above, which will not be repeated here.

[0384] In some embodiments, an i-th first sub-SLIV is obtained by encoding an indication value of a starting reference time unit group of the first uplink subband within the i-th first sub-time domain range and an indication value of the number of reference time unit groups of the first uplink subband within the i-th first sub-time domain range. The time domain position of the first uplink subband within the i-th first sub-time domain range is determined based on the i-th first sub-SLIV.

[0385] The calculation principle for the i-th first sub-SLIV is similar to that of the first sub-SLIV described above and is not repeated here. The total number of reference time unit groups used in the calculation is the total number of reference time unit groups within the i-th first sub-time domain, 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.

[0386] In some embodiments, an i-th second sub-SLIV is obtained by encoding an indication value of a starting reference time unit group of the first uplink subband within the i-th second sub-time domain range and an indication value of the number of reference time unit groups of the first uplink subband within the i-th second sub-time domain range. The time domain position of the first uplink subband within the i-th second sub-time domain range is determined based on the i-th second sub-SLIV.

[0387] The calculation principle for the i-th second sub-SLIV is similar to that of the second sub-SLIV described above and is not repeated here. The total number of reference time unit groups used in the calculation is the total number of reference time unit groups within the i-th second sub-time domain, 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.

[0388] The time domain position of the first uplink sub-band within the i-th group of sub-time domain ranges may be determined according to the i-th first sub-SLIV and the i-th second sub-SLIV.

[0389] Exemplarily, in cases where the first cycle is an integer multiple of a TDD dual cycle, the time domain position of the first uplink subband determined by the above method is shown in Figure 13. In Figure 13, Y = 2, the time domain position of the first uplink subband within the i-th first sub-time domain range is determined based on the starting reference time unit group S2 and the number of reference time unit groups L2, and the time domain position of the first uplink subband within the i-th second sub-time domain range is determined based on the ending reference time unit group E3 and the number of reference time unit groups L3.

[0390] Therefore, the embodiments of the present application support providing multiple optional time domain position determination methods in cases where the first cycle is a TDD single cycle, the first cycle is a TDD dual cycle, the first cycle is an integer multiple of a TDD single cycle, the first cycle is an integer multiple of a TDD dual cycle, etc., and have excellent flexibility in indicating or determining the time domain position of the first uplink subband, and support accurate and flexible determination of the time domain position of the first uplink subband through the first time domain position information for various communication scenarios. In particular, it supports determining a continuous time domain position for the first uplink subband, and the number of bits required for determination is relatively small.

[0391] In some embodiments, if there is a first reference time unit group in the time domain position determined according to the above method, and the first reference time unit group is a reference time unit group including uplink symbols, the UE performs at least one of the following: ignoring the indication of the first operation; ignoring the indication of the first operation for the first reference time unit group; ignoring the indication of the first operation for the uplink symbols in the first reference time unit group; not performing the first operation on the first reference time unit group; not performing the first operation on the uplink symbols in the first reference time unit group; not expecting the first reference time unit group to exist in the time domain position determined according to the first time domain position information; expecting that the first reference time unit group does not exist in the time domain position determined according to the first time domain position information.

[0392] Here, ignoring the instruction of the first operation can be understood as discarding the instruction after receiving the instruction of the first operation, or not performing the first operation after receiving the instruction of the first operation.

[0393] The "unexpected" behavior is the expectation and requirement of the UE side. The network device side will try not to perform the behavior that the UE side does not expect, but does not rule out the possibility that the network device side does not meet the "unexpected" behavior of the UE side.

[0394] The "expected" behavior is also the expectation and demand of the UE side. The network device side will execute the behavior expected by the UE side as much as possible, but it does not rule out the possibility that the network device side does not meet the "expected" behavior of the UE side.

[0395] 6. About the second time domain location information

[0396] In some embodiments, the time domain position of the first uplink subband is determined according to the second time domain position information.

[0397] In some embodiments, the second time domain position information includes a first bitmap. The method of determining the time domain position of the first uplink subband based on the bitmap supports both continuous and discrete time domain position determination for the first uplink subband, which is flexible.

[0398] In some embodiments, the first configuration information is used to determine a time domain position of the first uplink subband within a first time domain range in a first cycle.

[0399] In some embodiments, the time domain position of the first uplink subband within the first time domain range in the first cycle is determined according to a first bitmap, and each reference time unit group within the first time domain range corresponds one-to-one to each bit in the first bitmap.

[0400] Determining the time domain position of the first uplink subband according to the bitmap includes at least the following two methods:

[0401] Mode 1: The number of bits in the first bitmap 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.

[0402] The number of bits in the first bitmap may also be understood as the length of the first bitmap.

[0403] 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 according to the length of the first time domain range and the number of bits in the first bitmap.

[0404] 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 according to the quotient of the length of the first time domain range and the number of bits in the first bitmap.

[0405] Taking the time domain unit as a time slot 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 according to the quotient of the length of the first time domain range and the number of bits in the first bitmap.

[0406] Taking the time domain unit as a symbol as an example, the number of symbols in each reference time unit group within the first time domain range is determined by the UE according to the quotient of the length of the first time domain range and the number of bits in the first bitmap.

[0407] In some embodiments, the number of time domain units in each reference time unit group within the first time domain range is a rounded-up result or a rounded-down result of a quotient of a length of the first time domain range and a number of bits in the first bitmap.

[0408] Exemplarily, the communication protocol stipulates 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. The B bits correspond one-to-one with the B reference time unit groups. Exemplarily, the B bits are arranged from high to low and correspond one-to-one with the B reference time unit groups.

[0409] Assuming that the number of time domain units in the first time domain range is denoted by M′ and the number of time domain units in the reference time unit group is denoted by G′, then or in, Indicates rounding up. Indicates rounding down.

[0410] In some embodiments, among the B reference time unit groups, the number of time domain units in some reference time unit groups is different.

[0411] In some embodiments, among the B reference time unit groups, the first The reference time unit group contains symbols or time slots, followed by Time unit groups contain symbols / time slot.

[0412] For example, as shown in FIG9 , B=20, M′=50 symbols, The reference time unit groups corresponding to the first 10 bits arranged from high to low in the first bitmap include symbols. The reference time unit groups corresponding to the last 10 bits arranged from high to low in the first bitmap include symbols.

[0413] For example, as shown in FIG14 , the first configuration information configuration B=12, M′=50 symbols, These 12 bits are represented as B0 to B11, and these 12 bits correspond one-to-one to 12 reference time unit groups. The first two reference time unit groups of the 12 reference time unit groups each include 5 symbols, and the last 10 reference time unit groups each include 4 symbols.

[0414] Mode 2: The number of bits in the first bitmap 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.

[0415] The number of bits in the first bitmap may also be understood as the length of the first bitmap.

[0416] In some embodiments, the number of bits in the first bitmap is determined based on the first time domain range and the reference time unit group.

[0417] In some embodiments, the number of bits in the first bitmap is determined according to a quotient of a length of the first time domain range and a number of time domain units in the reference time unit group.

[0418] If the time domain unit is a time slot as an example, the number of bits in the first bitmap is determined by the UE according to the quotient of the length of the first time domain range and the number of time slots in the reference time unit group.

[0419] Taking the time domain unit as a symbol as an example, the number of bits in the first bitmap is determined by the UE according to the quotient of the length of the first time domain range and the number of symbols in the reference time unit group.

[0420] In some embodiments, the number of bits in the first bitmap is a result of rounding up or rounding down a quotient of the length of the first time domain range and the number of time slots in the reference time unit group.

[0421] Exemplarily, the number of time domain units in a reference time unit group is G' as agreed by the communication protocol or configured by the first configuration information. Assume that the number of time domain units in the first time domain range is denoted by M' and the number of bits in the first bitmap is denoted by B.

[0422] or, in, Indicates rounding up.

[0423] The B bits correspond one-to-one to the B reference time unit groups. Exemplarily, the B bits are arranged from high to low and correspond one-to-one to the B reference time unit groups.

[0424] However, there may be a situation where the first time domain range cannot be equally divided into B reference time unit groups. In this case, the number of time domain units in some of the reference time unit groups may be adjusted separately.

[0425] For example, as shown in FIG15 , the communication protocol stipulates that G′=6 symbols, that is, the communication protocol stipulates that a reference time unit group includes 6 symbols. If M′=50 symbols, then Therefore, the first bitmap includes 9 bits, represented as B0 to B8, and these 9 bits correspond one-to-one to the 9 reference time unit groups from high to low. The number of symbols in the first reference time unit group of these 9 reference time unit groups is adjusted to G′-M′mod G′=6-50mod 6=2, and the number of symbols in the other reference time unit groups remains G′=6 symbols. Alternatively, the number of symbols in the last reference time unit group of these 9 reference time unit groups is adjusted to G′-M′mod G′=6-50mod 6=2, and the number of symbols in the other reference time unit groups remains G′=6 symbols.

[0426] For example, the first configuration information configures G′=4 symbols, that is, the first configuration information configures a reference time unit group including 4 symbols. If M′=50 symbols, then Therefore, the first bitmap includes 13 bits, which correspond one-to-one to the 13 reference time unit groups from high to low bits. G′-M′ mod G′ = 4-50 mod 4 = 2. The number of symbols in the first of the nine reference time unit groups is adjusted to 2, while the number of symbols in the other reference time unit groups remains at 4. Alternatively, the number of symbols in the last of the nine reference time unit groups is adjusted to 2, while the number of symbols in the other reference time unit groups remains at 4.

[0427] The above-mentioned method of determining the first time domain range based on the bit map is applicable to the case where the first period is the first TDD uplink and downlink transmission period, the case where the first period is the sum of the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period, the case where the first period is an integer multiple of the first TDD uplink and downlink transmission period, and the case where the first period is an integer multiple of the sum of the first TDD uplink and downlink transmission period and the second TDD uplink and downlink transmission period. That is to say, when determining the first time domain range, it is not necessary to consider whether the first period can be divided into multiple sub-periods, but to regard the first period as a whole to agree on or configure the various parameters required to determine the first time domain range.

[0428] In some embodiments, considering that the first period is the sum of the first TDD uplink and downlink transmission period and the second TDD uplink and 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 position information includes a first sub-bit bitmap and a second sub-bit bitmap. The time domain position of the first uplink subband within the first sub-time domain range can be determined according to the first sub-bit bitmap, and the time domain position of the first uplink subband within the second sub-time domain range can be determined according to the second sub-bit bitmap. The position of the first uplink subband within the first sub-time domain range and the position within the second sub-time domain range are determined separately by two sub-bit bitmaps, so that the design of the time domain position of the first uplink subband is more flexible and easier to adapt to the delay requirements, capacity requirements, reliability requirements, etc. in different communication scenarios.

[0429] In some embodiments, the first sub-bitmap is the same as or different from the second sub-bitmap.

[0430] In some embodiments, the first sub-bitmap and the second sub-bitmap are determined in the same or different manners.

[0431] In fact, the method for determining the time domain position of the first uplink subband based on the first sub-bit bitmap and the second sub-bit bitmap can refer to the above-mentioned method 1 and method 2. The difference is that when calculating the first sub-bit bitmap, the number of time domain units M1′ within the first sub-time domain range replaces the number of time domain units M′ within the first time domain range; when calculating the second sub-bit bitmap, the number of time domain units M2′ within the second sub-time domain range replaces the number of time domain units M′ within the first time domain range. The details will not be repeated here.

[0432] In some embodiments, taking into account the situation where the first period is X times the first TDD uplink and downlink transmission period, the first time domain range includes X first sub-time domain ranges, and the time domain position of the first uplink subband within the first sub-time domain range can be determined based on the first sub-bit bitmap. The X first sub-time domain ranges correspond to X first sub-bit bitmaps, respectively. In this case, the second time domain position information includes X first sub-bit bitmaps, and the time domain position of the first uplink subband within each first sub-time domain range can be determined respectively through the X sub-bit bitmaps, so that the time domain position of the first uplink subband has a more flexible design and is more easily adapted to the delay requirements, capacity requirements, reliability requirements, etc. in different communication scenarios.

[0433] Determining the i-th first sub-bitmap among the X first sub-bitmaps is similar to determining the first sub-bitmap described above. The difference is that when calculating the i-th first sub-bitmap, the number of time-domain units within the i-th first sub-time-domain range is replaced by the number of time-domain units within the first time-domain range. This is not further described here.

[0434] In some embodiments, considering that the first period is Y times the first TDD uplink and downlink transmission period and the second TDD uplink and 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 subband within the first sub-time domain range can be determined based on the first sub-bitmap, and the time domain position of the first uplink subband within the second sub-time domain range can be determined based on the second sub-bitmap. In this case, the second time domain position information includes Y sub-bitmap groups, each of which includes a first sub-bitmap and a second sub-bitmap. The time domain position of the first uplink subband within the first sub-time domain range and the time domain position of the second sub-time domain range can be determined independently using the first sub-bitmap and the second sub-bitmap, or the time domain position of the first uplink subband in each sub-time domain range group can be determined separately using the Y sub-bitmap groups. This allows for a more flexible design of the time domain position of the first uplink subband, making it easier to adapt to latency requirements, capacity requirements, reliability requirements, etc. in different communication scenarios.

[0435] The time domain position of the first uplink subband within the i-th group of sub-time domain ranges 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 by the number of time domain units within the first time domain range, which is not repeated here. 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 by the number of time domain units within the first time domain range, which is not repeated here.

[0436] Therefore, the embodiments of the present application support providing a variety of optional bit map determination methods when the first cycle is a TDD single cycle, the first cycle is a TDD dual cycle, the first cycle is an integer multiple of a TDD single cycle, the first cycle is an integer multiple of a TDD dual cycle, etc., and have excellent flexibility in determining or determining the time domain position of the first uplink subband, and support accurate and flexible determination of the time domain position of the first uplink subband through a bit map for various communication scenarios.

[0437] In some embodiments, if there is a first reference time unit group in the time domain position determined according to the second time domain position information, and the first reference time unit group is a reference time unit group including uplink symbols, the UE performs at least one of the following: ignoring the indication of the first operation; ignoring the indication of the first operation for the first reference time unit group; ignoring the indication of the first operation for the 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 on the uplink symbols in the first reference time unit group; not expecting the first reference time unit group to exist in the time domain position determined according to the second time domain position information; expecting that the first reference time unit group does not exist in the time domain position determined according to the second time domain position information.

[0438] Here, ignoring the instruction of the first operation can be understood as discarding the instruction after receiving the instruction of the first operation, or not performing the first operation after receiving the instruction of the first operation.

[0439] Among them, the "unexpected" behavior is the expectation and demand of the UE side. The network device side will try not to perform the behavior that the UE side does not expect, but it does not rule out the possibility that the network device side does not meet the "unexpected" behavior of the UE side.

[0440] The "expected" behavior is also the expectation and demand of the UE side. The network device side will execute the behavior expected by the UE side as much as possible, but it does not rule out the possibility that the network device side does not meet the "expected" behavior of the UE side.

[0441] It should be noted that the above six aspects can be used individually or in free combination.

[0442] Exemplarily, the time domain position of the first uplink subband is determined based on the first period. Alternatively, the time domain position of the first uplink subband is determined based on the first subcarrier spacing. Alternatively, the time domain position of the first uplink subband is determined based on the first time domain range. Alternatively, the time domain position of the first uplink subband is determined based on the reference time unit group. Alternatively, the time domain position of the first uplink subband is determined based on the first time domain position information. Alternatively, the time domain position of the first uplink subband is determined based on the second time domain position information.

[0443] Exemplarily, the time domain position of the first uplink subband is determined according to the first period and the first subcarrier spacing. Alternatively, the time domain position of the first uplink subband is determined according to the first period and the first time domain range. Alternatively, the time domain position of the first uplink subband is determined according to the first time domain range and the reference time unit group. Alternatively, the time domain position of the first uplink subband is determined according to the first period, the first time domain range, and the reference time unit group. Alternatively, the time domain position of the first uplink subband is determined according to the first time domain range and the first time domain position information. Alternatively, the time domain position of the first uplink subband is determined according to the first period and the first time domain position information. Alternatively, the time domain position of the first uplink subband is determined according to the first time domain range and the second time domain position information. Alternatively, the time domain position of the first uplink subband is determined according to the first period and the second time domain position information, and so on. Some examples of combined use have been introduced above, and all possibilities will not be listed here one by one.

[0444] Step 430: Perform uplink transmission in the first uplink subband according to the time domain position of the first uplink subband.

[0445] In some embodiments, the first uplink subband is an uplink subband in the SBFD technology. Alternatively, the first uplink subband may be an uplink subband in the XDD technology. Alternatively, the first uplink subband may be an uplink subband corresponding to a time domain unit supporting a first operation, where the first operation refers to a technology capable of simultaneously transmitting and receiving data on different subbands corresponding to the same time domain unit.

[0446] In some embodiments, if a first reference time unit group exists in the time domain position of the 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, the UE performs at least one of the following: ignoring the first configuration information; ignoring the configuration information for the first reference time unit group in the first configuration information; ignoring the configuration information for the uplink symbols in the first reference time unit group in the first configuration information; not performing the first operation in the first reference time unit group; not performing the first operation on the uplink symbols in the first reference time unit group.

[0447] Ignoring the first configuration information can be understood as discarding the first configuration information after receiving it, or as not using the configuration in the first configuration information after receiving it.

[0448] 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 within the first reference time unit group do not include the first uplink subband; the UE assumes that the uplink symbols within the first reference time unit group do not include the first uplink subband; the UE does not expect the first reference time unit group to exist in the time domain position determined based on the first configuration information; the UE expects that the first reference time unit group does not exist in the time domain position indicated based on the first configuration information.

[0449] Among them, the first reference time unit group does not include the first uplink subband, which can be understood as the first reference time unit group does not include the time domain unit corresponding to the first uplink subband, or it can be understood as the time domain unit occupied by the first uplink subband is not located in the first reference time unit group, or it can be understood as the frequency domain resources corresponding to the first reference time unit group do not include the first uplink subband.

[0450] 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 may actually not include the uplink subband. Regardless of whether it actually includes the uplink subband 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 is not further described.

[0451] Among them, the "unexpected" behavior is the expectation and demand of the UE side. The network device side will try not to perform the behavior that the UE side does not expect, but it does not rule out the possibility that the network device side does not meet the "unexpected" behavior of the UE side.

[0452] The "expected" behavior is also the expectation and demand of the UE side. The network device side will execute the behavior expected by the UE side as much as possible, but it does not rule out the possibility that the network device side does not meet the "expected" behavior of the UE side.

By separately designing the above six aspects, a reliable and feasible solution is provided for determining the time domain position of the first uplink subband. The advantages of these six aspects when designed separately still exist when used in free combination.
