[0100] The static signaling or semi-static signaling may include, for example, Radio Resource Control (RRC) signaling and System Information Block (SIB), and the dynamic signaling may include, for example, Downlink Control Information (DCI).

[0101] In addition, the signaling used to configure the time domain format may also include a Media Access Control Control Element (MAC CE). The MAC CE may be classified as static signaling or semi-static signaling, or dynamic signaling, and the present disclosure does not limit this.

[0102] The SIB or RRC signaling may carry time division duplex uplink and downlink common configuration (TDD-UL-DL-ConfigCommon) signaling, and the RRC signaling may include time division duplex uplink and downlink dedicated configuration (TDD-UL-DL-Configdedicated) signaling.

[0103] In some embodiments, the semi-static signaling and dynamic signaling can be cell-level signaling or terminal-level signaling. Cell-level signaling can be signaling applied to a cell, for example, all terminals within a cell, while terminal-level signaling can be signaling applied to one or more specific terminals.

[0104] For example, the cell-level signaling may include cell-level semi-static signaling (e.g., TDD-UL-DL-ConfigCommon signaling) and cell-level dynamic signaling (e.g., Group Common Downlink Control Information (Group Common DCI)).

[0105] For example, the terminal-level signaling may include terminal-level semi-static signaling (eg, TDD-UL-DL-ConfigDedicated signaling) and terminal-level dynamic signaling (eg, terminal-specific DCI).

[0106] In some embodiments, the network device may configure the time domain format for the terminal through static signaling (eg, semi-static signaling) or dynamic signaling.

[0107] In some embodiments, the network device may configure the time unit format for the terminal through static signaling (eg, semi-static signaling) or dynamic signaling.

[0108] The following takes the case where the network configures the time unit format for the terminal through downlink control information (DCI) as an example to exemplify how the network device configures the time unit format for the terminal. Wherein, DCI may belong to dynamic signaling.

[0109] In some embodiments, DCI may include DCI format 2_0, which may also be referred to as DCI2_0. DCI 2_0 may indicate the time unit format through a carried time unit format indication (Slot Format Indicator, SFI) index.

[0110] DCI 2_0 can indicate the time unit format of at least one time slot (also known as the time division duplexing (TDD) structure of the time slot) through the SFI-index. For example, the indicated at least one time slot starts when the terminal monitors DCI 2_0, and the length (number of slots) is greater than or equal to the listening period of DCI 2_0. For example, the structure of DCI 2_0 can be as follows:

[0111] The following information is sent via DCI 2_0, where the cyclic redundancy check (CRC) is scrambled by the SFI-RNTI (Radio Network Temporary Identity):

[0112] - If the higher layer parameter slotFormatCombToAddModList is configured,

[0113] -Slot Format Indicator 1, Slot Format Indicator 2,…, Slot Format Indicator N.

[0114] It can be seen that DCI 2_0 can include one or more SFI-indexes, and can further indicate one or more time unit formats of a specific cell through the SFI-index. For example, the SFI-index can indicate the identifier of a specific time slot format combination among multiple configured time slot format combinations (slotFormatCombination). The time slot format combination corresponding to the identifier includes one or more time unit formats, for example, up to 256 time slot formats. For example, the relevant information element (IE) of the time unit format combination is as follows:

[0115]

[0116] In some embodiments, the SFI-index may also indicate configuration information related to the time unit format combination, such as shown in Table 1 below:

[0117]

[0118] Table 1

[0119] In some embodiments, DCI 2_0 may belong to terminal-level signaling, and group scheduling may be performed for each terminal (per UE).

[0120] In some embodiments, DCI 2_0 may be cell-level signaling, and may be used to schedule terminals within the cell.

[0121] In some embodiments, the network device may configure a time domain format pattern for the terminal through semi-static signaling and / or dynamic signaling. For example, the time domain format pattern may be called a TDD pattern.

[0122] For example, the network device can configure a time domain format pattern for the terminal through time division duplex uplink and downlink configuration common (tdd-UL-DL-ConfigurationCommon) signaling and / or time division duplex uplink and downlink configuration specific (tdd-UL-DL-ConfigurationDedicated). The terminal can determine the time domain type of the time domain unit based on the time domain format pattern, such as U (uplink), D (downlink), F (flexible), etc. The time domain unit includes at least one of the following: frame, subframe, slot, mini-slot, and symbol.

[0123] DCI 2_0 may further indicate a time unit format for a time domain unit of type F in the time domain format pattern. For example, for a time slot of type F, the time unit format indicated by DCI 2_0 may be used to determine the time domain type of a symbol in the time slot. For example, for a symbol of type F, the time unit format indicated by DCI 2_0 may be used to determine the time domain type of the symbol.

[0124] For time domain units determined to be U or D based on the time domain format pattern, the terminal does not expect DCI 2_0 to indicate different types for these time domain units (for example, indicating U type time domain units as D or F types, and indicating D type time domain units as U or F types).

[0125] In some embodiments, the time unit format may be indicated by a row index in a list. As shown in Table 2 below, the time unit format defined in the table may include one or two uplink and downlink conversion points:

[0126]

[0127] Table 2

[0128] Figure 1B Schematic diagram of a time unit format according to an embodiment of the present disclosure.

[0129] like Figure 1B As shown, for example, DCI 2_0 includes N SFIs, where SFI #3 can indicate time unit format combination #j for cell #i. Time unit format combination #j includes M time unit formats, where the minimum value of M is 1 and the maximum value is 256.

[0130] Among the M time unit formats, for example, time unit format #2 has one uplink / downlink switching point, specifically DDDDDDDDDDDDFU; for example, time unit format #M has two uplink / downlink switching points, specifically DDDDDFUDDDDDFU.

[0131] After determining the time unit format, the terminal can determine the type of the time domain unit according to the time unit format. For example, if the time slot format is the above-mentioned time unit format #2, then it can be determined that the type of the first 12 symbols in the corresponding time slot is D, the type of the 13th symbol is F, and the type of the 14th symbol is U.

[0132] According to an embodiment of the present disclosure, the network device can indicate the time domain format to the terminal through indication information, and the terminal can determine the type of time domain unit (e.g., symbol) in the time slot based on the time domain format, such as uplink, downlink, flexible, etc., so that the terminal can communicate in an appropriate manner on each time domain unit during subsequent communication.

[0133] It should be noted that, in addition to determining the time domain format according to the indication information, the terminal may also determine the time domain format based on predefined rules. In this case, the network device may also determine the time domain format based on the predefined rules.

[0134] For example, if the protocol specifies a time domain format, or the terminal pre-stores a correspondence between scenarios and time domain formats, then when the terminal communicates in a specific scenario, it can determine the time domain format corresponding to the specific scenario based on the correspondence.

[0135] In some embodiments, the time unit format is used to indicate a time domain type corresponding to at least one symbol in a time slot or a sub-time slot.

[0136] For example, the time unit format is used to indicate the time domain type corresponding to at least one symbol in a time slot. After determining the time unit format, the terminal can determine the time domain type corresponding to at least one symbol in the time slot based on the time unit format. For example, for a specific time slot, the time slot format is DDDDDDDDDDDDFU. Based on this, the terminal can determine that the type of the first 12 symbols in the time slot is D, the type of the 13th symbol is F, and the type of the 14th symbol is U.

[0137] For example, a time unit format may be used to indicate a time domain type corresponding to at least one symbol in a sub-time slot. In this case, the time unit format may be referred to as a sub-time unit format. After determining the sub-time unit format, the terminal may determine the time domain type corresponding to at least one symbol in the sub-time slot based on the sub-time unit format.

[0138] The number of symbols contained in a sub-time slot may be less than the number of symbols contained in a time slot. For example, a sub-time slot may contain 2, 7, or other symbols. For example, if a sub-time slot contains 2 symbols, and the sub-time unit format is DF, the terminal can determine that the type of the first symbol in the sub-time slot is D and the type of the second symbol is F.

[0139] In some embodiments, the time unit format is determined based on at least one of the following included in the indication information:

[0140] the number of symbols that at least one time-domain type lasts;

[0141] The order of the time domain types.

[0142] In some embodiments, when the order of time domain types is fixed, such as agreed upon by protocol, the terminal only needs to determine the time domain units corresponding to each time domain type in the cycle based on the number of time domain units lasted by at least one time domain type.

[0143] It should be noted that in some embodiments, information such as the number of symbols continued by at least one time domain type of the time cell format, the order of the time domain types, etc., in addition to being indicated by the indication information, can also be determined based on predefined rules (such as protocol agreements), and the present disclosure does not limit this.

[0144] In some embodiments, the number of time domain units that each time domain type lasts for includes at least one of the following:

[0145] the number of symbols that the first time-domain type lasts;

[0146] the number of symbols that the second time domain type lasts;

[0147] The number of symbols that the third time domain type lasts.

[0148] In some embodiments, the first time domain type is uplink, the second time domain type is downlink (D), and the third time domain type is flexible (F); or, the first time domain type is uplink (U), the second time domain type is flexible, and the third time domain type is downlink; or, the first time domain type is downlink, the second time domain type is uplink, and the third time domain type is flexible; or, the first time domain type is downlink, the second time domain type is flexible, and the third time domain type is downlink; or, the first time domain type is flexible, the second time domain type is uplink, and the third time domain type is downlink; or, the first time domain type is flexible, the second time domain type is uplink, and the third time domain type is downlink; or, the first time domain type is flexible, the second time domain type is downlink, and the third time domain type is uplink.

[0149] In some embodiments, in addition to the above-mentioned traditional time domain types D, F, and U, the present disclosure can also expand the time domain type of the time domain unit and introduce a new time domain type. Then the description of the three time domain types in the above embodiments can also be implemented based on the newly introduced time domain type.

[0150] For example, the new time domain type may include the SFBD type (for example, called the fourth time domain type), wherein the SBFD type time domain unit may include a downlink time domain unit configured with an uplink subband, an uplink time domain unit configured with a downlink subband, a flexible time domain unit configured with an uplink subband, and a flexible time domain unit configured with a downlink subband.

[0151] For example, the new time domain type may include a transmission direction type (eg, called a fifth time domain type), wherein a time domain unit of the transmission direction type may include a time domain unit in which a transmission direction is specified by a configuration network indication or a predefined rule.

[0152] In order to simplify the description and facilitate understanding, the following embodiments are mainly described as an example when the time domain type includes the traditional three time domain types.

[0153] Figure 3 This is a schematic diagram illustrating a method of determining a time domain type corresponding to at least one symbol in a time slot according to an embodiment of the present disclosure.

[0154] like Figure 3 As shown, the number of time domain units that each time domain type lasts for is:

[0155] The number of symbols N1 that the first time domain type lasts;

[0156] The second time domain type lasts for a number of symbols N2.

[0157] Taking the time unit including the time slot as an example, for example, the terminal can determine the time slot to which the time unit format is applicable. Among the multiple symbols contained in the time slot, the first N1 symbols are symbols of the first time domain type, the last N2 symbols are symbols of the second time domain type, and the other symbols all belong to the third time domain type.

[0158] Taking the time unit including a sub-time slot as an example, for example, the terminal may determine the sub-time slot to which the time unit format is applicable. In this case, the time unit format may be referred to as a sub-time unit format.

[0159] A time slot may include M sub-time slots, where M may be an integer greater than 1. The i-th sub-time slot in the M sub-time slots lasts for ni symbols, and n1+n2+...+nM symbols, i.e., the total number of symbols included in the time slot in which the M sub-time slots are located, then the time domain type corresponding to at least one symbol in the time slot in which the M sub-time slots are located may also be determined based on the M sub-time slot structure corresponding to the M sub-time slots.

[0160] When the sub-time unit format determined by the terminal is applicable to the i-th sub-time slot, based on the above N1 and N2, it can be determined that among the ni symbols corresponding to the i-th sub-time slot, the first N1 symbols are symbols of the first time domain type, the last N2 symbols are symbols of the second time domain type, and the other symbols all belong to the third time domain type.

[0161] In addition, in some embodiments, when a new time domain type is introduced, the time domain type is not limited to the above three time domain types. In this case, when determining the number of time domain units that at least one time domain type lasts for each new time domain type introduced, the number of time domain units that one more time domain type lasts for can be determined.

[0162] For example, when the SBFD time domain type is introduced, Figure 3 Taking the shown embodiment as an example, there are four time domain types. In addition to determining the number N1 of symbols continued by the first time domain type and the number N2 of symbols continued by the second time domain type, the terminal can also determine the number of symbols continued by the third time domain type, or determine the number of symbols continued by the SBFD time domain type. Then, after determining the number of symbols continued by the three time domain types, in the time slot or sub-time slot applicable to the time slot structure, the other symbols all belong to the fourth time domain type.

[0163] Taking the order of time domain types {DF SBFD U} as an example, the terminal can determine the distribution of time domain types D, U and SBFD time domain units in a specific time slot or sub-time slot based on network device indication or predefined method, thereby determining that the remaining time domain unit type in the specific time slot or sub-time slot is F; it can also determine the distribution of time domain types D, F and U time domain units in a specific time slot or sub-time slot based on network device indication or predefined method, thereby determining that the remaining time domain unit type in the specific time slot or sub-time slot is SBFD.

[0164] It should be noted that in the above implementation, the present disclosure mainly determines the time domain type corresponding to at least one symbol in a time slot based on parameters such as the number of time domain units (e.g., symbols) continued by at least one time domain type and the order of the time domain types. However, the method of determining the time domain type corresponding to at least one symbol in a time slot in the present disclosure is not limited to this. For example, the network device can directly indicate the time domain type of each time domain unit. For example, for 10 time domain units, the time domain type of these 10 time domain units can be indicated by 20 bits, with each 2 bits corresponding to 1 time domain unit. For example, the value of 2 bits is 00, which is used to indicate that the time domain type of the corresponding time domain unit is downlink (D); the value of 2 bits is 01, which is used to indicate that the time domain type of the corresponding time domain unit is uplink (U); the value of 2 bits is 10, which is used to indicate that the time domain type of the corresponding time domain unit is flexible (F); the value of 2 bits is 11, which can be used as a reserved bit or used to indicate other time domain types, such as the SBFD type in the above embodiment.

[0165] For example, it is defined directly based on a predefined method. For example, a specific time domain format is determined directly based on a predefined method. For example, the time domain format corresponding to a specific index (eg, 101) is DDDDDFFUUUUUUU, and the terminal determines that the time domain format corresponding to index 101 is DDDDDFFUUUUUUU.

[0166] In some embodiments, the time unit format is determined based on a time unit format indication index included in the indication information.

[0167] In some embodiments, the time unit format is determined based on the index and a mapping relationship between a predefined or network-indicated time unit format indication index and a time unit format.

[0168] For example, the mapping relationship may be represented in a table or ensured in other ways, and the present disclosure is not limited thereto.

[0169] For example, when the mapping relationship is represented by a table, the table can be a traditional table, such as Table 2 mentioned above; or, the table can be a table formed by introducing a time unit format of a new time domain type order on the basis of a traditional table, for example, the time unit format of the new time domain type order is set in at least one row from rows 56 to 254; or, the table may not contain some or all of the time unit formats in the traditional table.

[0170] For example, the indication information sent by the network device to the terminal may include an index, such as SFI-index. The terminal may determine the time unit format corresponding to the SFI-index in the mapping relationship as the time unit format indicated by the network device.

[0171] In some embodiments, the mapping relationship is defined based on at least one of the following:

[0172] the number of symbols that at least one time-domain type persists;

[0173] The order of the time domain types.

[0174] In some embodiments, the mapping relationship can be determined based on the number of symbols continued by at least one time domain type. For example, the mapping relationship can include an index and a time unit format, wherein the time unit format can be determined based on the number of symbols continued by at least one time domain type. The relevant determination method can refer to Figure 3 The examples shown are not described in detail in this disclosure.

[0175] In this case, instead of indicating the time domain type for each of the 14 symbols as shown in Table 2, the mapping relationship may indicate the time domain type of only some symbols, and the terminal can also determine the time domain type of each symbol.

[0176] It should be noted that in addition to being determined based on the above-mentioned methods such as the number of symbols sustained by an index or at least one time domain type, the time unit format can also be determined based on predefined rules (such as protocol agreements) or the type of each symbol indicated by a network device. For example, for the 14 symbols in a time slot, the network device can indicate the time domain type of each of the 14 symbols respectively, and the terminal can determine the time domain type of each of the 14 symbols accordingly.

[0177] In some embodiments, the mapping relationship may be determined based not only on the number of symbols continued by at least one time domain type, but also on the order of the time domain types. For example, the mapping relationship may include an index and a time unit format, where the time unit format may be determined based on the number of symbols continued by at least one time domain type and the order of the time domain types.

[0178] Additionally, in some embodiments, the time slot format may also be determined based on the number of symbols that at least one time domain type continues, and the order of the time domain types.

[0179] It should be noted that in some embodiments, information such as the number of symbols continued by at least one time domain type that defines the mapping relationship, the order of the time domain types, etc., can be indicated by the network device or determined based on predefined rules (such as protocol agreements), and the present disclosure does not limit this.

[0180] In some embodiments, with the development of communication technology, in order to meet different communication needs, content related to scenarios is introduced, where a scenario can also be called a function set.

[0181] However, since the communication needs between the terminal and the network device may be different in different scenarios, in the above-mentioned solution where the network device indicates the time domain format to the terminal, since there is no clear scenario to which the time domain format is applicable, the terminal will use the same time domain format for communication in each scenario, which is difficult to meet the communication needs in different scenarios.

[0182] In some embodiments, the scenario includes at least one of the following:

[0183] Subband full duplex (SBFD);

[0184] Communication and perception (e.g., abbreviated as gantong, which can be translated as sensing);

[0185] Time Division Duplex (TDD);

[0186] Energy saving, such as network energy saving and terminal energy saving;

[0187] Artificial Intelligence (AI).

[0188] Among them, the TDD scenario belongs to the traditional communication scenario, which will not be described in detail in this disclosure. The following is an illustrative description of several other scenarios through several embodiments.

[0189] In some embodiments, in an SBFD scenario, the network device can configure an uplink subband (UL subband) in a downlink time domain unit or a flexible time domain unit, so that in the frequency domain resources corresponding to the downlink time domain unit or the flexible time domain unit, uplink communication can be performed within the uplink subband, and downlink communication can be performed in the frequency domain resources outside the uplink subband.

[0190] Alternatively, in the SBFD scenario, the network device can configure a downlink subband (DL subband) in the uplink time domain unit or the flexible time domain unit, so that in the frequency domain resources corresponding to the uplink time domain unit or the flexible time domain unit, downlink communication can be performed within the downlink subband, and uplink communication can be performed in the frequency domain resources outside the downlink subband.

[0191] In some embodiments, in sensing scenarios, Integrated Sensing and Communication (ISAC) can be implemented in the communication system to achieve the complementary functions of communication and perception, which can be applied to scenarios such as high-precision positioning tracking, synchronous imaging, and map construction. In sensing scenarios, time domain units need to be reasonably configured to realize the functions of communication and perception.

[0192] In some embodiments, energy-saving technologies can be used to achieve energy saving for network devices and / or terminals, which helps reduce energy consumption during communication. To meet energy-saving requirements, the time domain units in the communication process need to be properly configured.

[0193] In some embodiments, communication can be combined with AI to enhance the automation and skills of network operation and maintenance, while enhancing the functions and characteristics of network maintenance. For example, the monitoring results of various monitoring operations (such as the results of minimized drive tests, channel state information, etc.) can be predicted based on the model determined by AI. For example, the demodulation results corresponding to the data modulated by each modulation method can be predicted based on the model determined by AI. The combination of communication and AI is not limited to the above examples, and this disclosure does not limit this. In the case of combining communication with AI, it is also necessary to reasonably configure the time domain unit.

[0194] It can be seen that in the above different scenarios, there are different requirements for time domain unit configuration, which will lead to different time domain formats being the most suitable for each scenario.

[0195] In some embodiments, if the time domain format can only be configured in the order of {DFU}, for example, taking 5 time slots as an example, if only downlink time slots and uplink time slots are included and flexible time slots are not included, then the time domain format can be DDDUU, DDUUU, etc., that is, D-type time slots must be located before U-type time slots. If flexible time slots are also included in the 5 time slots, the time domain format can be DDFUU, DDDFU, etc., that is, F-type time slots must be located after D-type time slots and before U-type time slots.

[0196] This method of determining the time domain format based on a fixed order will severely limit the scenarios in which the time unit format can be used. For example, in TDD scenarios, the main consideration is to receive downlink information first and then provide feedback on the reception status. Therefore, the time domain format determined based on the {DFU} order can be applicable to TDD scenarios, but for other scenarios, the time domain format determined based on the {DFU} order is not necessarily applicable.

[0197] For example, for the SBFD scenario, since the network device configures an uplink subband in the downlink time domain unit or the flexible time domain unit, or configures a downlink subband in the uplink time domain unit or the flexible time domain unit, the network device and / or the terminal can perform both uplink and downlink communications on these time domain units configured with subbands. Therefore, there is no need to limit the downlink time domain unit to be in front and the uplink time domain unit to be in the back.

[0198] Therefore, in response to the above problem, the present disclosure further proposes that determining the time domain unit corresponding to at least one time domain type is based not only on the number of time domain units continued by the at least one time domain type, but also on the order of the time domain types.

[0199] In some embodiments, the sequence of the time domain types includes at least one of the following sequences, or a cycle of any of the following sequences:

[0200] Upward, that is, {U};

[0201] Downward, that is, {D};

[0202] Flexible, i.e. {F};

[0203] Uplink, downlink, i.e. {UD};

[0204] Upward and flexible, namely {UF};

[0205] Uplink, flexible, downlink, or {UFD};

[0206] Uplink, downlink, flexible, that is, {UDF};

[0207] Flexible and upward, namely {FU};

[0208] Flexible, downstream, i.e. {FD};

[0209] Flexible, uplink, downlink, that is {FUD};

[0210] Flexible, downlink, uplink, or {FDU};

[0211] Downlink, Uplink, i.e. {DF};

[0212] Downstream, flexible, that is, {DU};

[0213] Downlink, flexible, uplink, namely {DFU};

[0214] Downlink, Uplink, Flexible, or {DUF}.

[0215] In some embodiments, the order of the time domain type includes one of the above orders, for example, the order included is {DFU}. Taking 14 symbols as an example, the time domain format can be, for example, DDDDDDDDDDDDFU, DDDDDDDDDFFUUU, etc.

[0216] In some embodiments, the order of the time domain type includes a cycle of the above-mentioned order, for example, the order included is {DFU}. Taking 14 symbols as an example, the time domain format can be, for example, DDDDDFUDDDDDFU, DDDFUDFUDFUDFU, etc.

[0217] In some embodiments, the order of the time domain type includes a combination of the above-mentioned multiple orders, for example, the order included is {DFU} and {FD}. Taking 14 symbols as an example, the time domain format can be DDDDDFUFFFDDDD, DDDFFUUFFFFFDD, etc.

[0218] In some embodiments, the order of the time domain type includes one of the above orders, for example, the order included is {DFU}. Taking 14 symbols as an example, the time domain format can be, for example, DDDDDDDDDDDDFU, DDDDDDDDDFFUUU, etc.

[0219] It should be noted that the order of time domain types is not limited to the above-mentioned determination methods. For example, the order of time domain types can also include a cycle of the above-mentioned multiple orders, or a combination of a cycle of at least one order and multiple orders. This disclosure does not limit this.

[0220] In this embodiment, the order of the time domain types is no longer fixed to {UFD}, but can be flexibly configured by the network device. For example, the network device can configure different time domain type orders for different scenarios, so that the time domain format (time domain unit corresponding to each time domain type) determined by the terminal based on the time domain type order can be applied to the corresponding scenario, which is conducive to ensuring that the terminal has relatively good communication quality when communicating based on the determined time domain format in the corresponding scenario.

[0221] For example, in the above Figure 3 In the embodiment shown, if the number of time domain units continued by at least one time domain type is determined based on a fixed time domain type order {UFD}, then the first time domain type is fixed to U, the second time domain type is fixed to D, and the third time domain type is fixed to F, which greatly limits the expansion of the time domain format.

[0222] Based on this embodiment, when the terminal determines the number of time domain units continued by at least one time domain type, it can consider the order of the time domain types configured by the network device. For example, if the order of the time domain types is {DFU}, then the first time domain type is D, the second time domain type is U, and the third time domain type is F, thereby achieving the expansion of the time domain format so that the time domain format can be applicable to more scenarios.

[0223] Similarly, when determining a mapping relationship based on the time domain type, the time domain format in the mapping relationship can also be expanded to make the time domain format applicable to more scenarios. For example, based on the traditional mapping relationship shown in Table 2, by considering the order of different time domain types, more time unit formats can be introduced, such as UUUUUUUUUUUUFD, UUUDDDFUUUDDDF, and other time unit formats.

[0224] It should be noted that, in some embodiments, in addition to the traditional time domain types D, F, and U, the present disclosure may also expand the time domain types of the time domain unit and introduce new time domain types, such as the aforementioned SFBD type and transmission direction type. When introducing new time domain types, the order of the aforementioned time domain types may be further expanded, for example, by adding the new time domain type before or after any traditional time domain type (such as the aforementioned D, F, U, etc.), and the present disclosure does not limit this.

[0225] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 and S202.

[0256] The technical solution of the present disclosure is further illustrated below through several embodiments.

[0257] Example 1:

[0258] The terminal receives indication information from the network device (for example, carried in dynamic signaling or semi-static signaling), and determines the time unit format according to the indication information.

[0259] Furthermore, the configurations included in this embodiment may include one or more of the following:

[0260] The time domain type of at least one time domain unit in a specific time slot is defined based on a time unit format;

[0261] The time domain type of at least one time domain unit in a specific time slot is defined based on the N sub-time unit formats;

[0262] The following describes the specific implementation of the above-mentioned scheme through specific examples of the present invention.

[0263] Example 1-1:

[0264] Based on the above analysis, in this embodiment, the indication information is carried in the dynamic signaling as an example. For example, the dynamic signaling includes DCI, and the indication information is used to indicate the time unit format corresponding to Ns time slots.

[0265] Exemplarily, the start time of the Ns time slots may be the time slot in which the terminal receives dynamic signaling, and Ns may be determined based on a signaling indication or a predetermined rule (eg, a protocol agreement).

[0266] Exemplarily, Ns is greater than or equal to the number of time slots included in the dynamic signaling blind detection period.

[0267] The time unit format for a particular time slot is based on one or more of the following definitions:

[0268] a number N1 of first time units (e.g., symbols) that the first time-domain format lasts;

[0269] The first number of time units N2 of the second time domain format;

[0270] Within a time range corresponding to the time slot, the terminal determines that the first N1 first time units in the time slot correspond to the first time domain format;

[0271] Within the time range corresponding to the time slot, the terminal determines that the last N2 first time units in the time slot correspond to the second time domain format.

[0272] Wherein, N1 and N2 are integers greater than or equal to 0.

[0273] The terminal determines that the remaining time units within the time range corresponding to the time slot correspond to the third time domain format, and the number of duration units of the third time domain format is equal to: the number of first time units in the time slot - N1 - N2. For related examples, please refer to Figure 3 , I will not go into details here.

[0274] Example 1:

[0275] Taking the first time unit as a symbol as an example, the first time domain format corresponds to the flexible time domain format F, and the second time domain format corresponds to the downlink D. Then the third time domain format corresponds to the uplink U, and the time domain format corresponds to the {FDU} structure. The corresponding time unit format pattern is repeatedly transmitted with the {FUD} structure.

[0276] Example 2:

[0277] Taking the first time unit as a symbol as an example, the first time domain format corresponds to the flexible time domain format F, and the second time domain format corresponds to the downlink U. Then the third time domain format corresponds to the uplink D, and the time domain format corresponds to the {FDU} structure. The corresponding time unit format pattern is repeatedly transmitted with the {FDU} structure.

[0278] Example 3:

[0279] Taking the first time unit as a symbol as an example, the first time domain format corresponds to the flexible time domain format D, and the second time domain format corresponds to the downlink F, then the third time domain format corresponds to the uplink U, and the time domain format corresponds to the {DUF} structure, and the corresponding time unit format pattern is repeatedly transmitted with the {DUF} structure.

[0280] Example 4:

[0281] Taking the first time unit as a symbol as an example, the first time domain format corresponds to the flexible time domain format U, and the second time domain format corresponds to the downlink D. The third time domain format corresponds to the uplink F, and the time domain format corresponds to the {UDF} structure. The corresponding time unit format pattern is repeatedly transmitted with the {UFD} structure.

[0282] Example 5:

[0283] Taking the first time unit as a symbol as an example, the first time domain format corresponds to the flexible time domain format U, and the second time domain format corresponds to the downlink F, then the third time domain format corresponds to the uplink D, and the time domain format corresponds to the {UDF} structure, and the corresponding time unit format pattern is repeatedly transmitted with the {UDF} structure.

[0284] Example 1-2:

[0285] Based on the above analysis, in this embodiment, the indication information is carried in the dynamic signaling as an example. For example, the dynamic signaling includes DCI, and the indication information is used to indicate the time unit format corresponding to Ns time slots.

[0286] Exemplarily, the start time of the Ns time slots may be the time slot in which the terminal receives dynamic signaling, and Ns may be determined based on a signaling indication or a predetermined rule (eg, a protocol agreement).

[0287] Exemplarily, Ns is greater than or equal to the number of time slots included in the dynamic signaling blind detection period.

[0288] The time unit format corresponding to a specific time slot (e.g., the time domain type of at least one time domain unit) can be defined based on M sub-time domain formats. Within the time range corresponding to the time slot, the first sub-time domain format lasts for M1 first time units, the second sub-time domain format lasts for M2 first time units, ..., and the i-th sub-time domain format lasts for Mi first time units, where M1 + M2 + ... MM = the number of first time units included in the time slot.

[0289] Within the time range corresponding to a time slot, the sub-time domain format is based on one or more of the following definitions:

[0290] a number N1 of first time units (e.g., symbols) that the first time-domain format lasts;

[0291] The first number of time units N2 of the second time domain format;

[0292] Within a time range corresponding to the sub-time slot, the terminal determines that the first N1 first time units within the time slot correspond to the first time domain format;

[0293] Within the time range corresponding to the sub-time slot, the terminal determines that the last N2 first time units in the time slot correspond to the second time domain format;

[0294] Wherein, N1 and N2 are integers greater than or equal to 0.

[0295] The terminal determines that the remaining time units within the time range corresponding to the sub-time slot correspond to the third time domain format, and the number of duration units of the third time domain format is equal to: the number of first time units in the sub-time slot - N1 - N2. For related examples, please refer to Figure 3 (Replace time slot with sub-time slot), which will not be described here.

[0296] Example 1:

[0297] Taking the first time unit as a symbol as an example, the first time domain format corresponds to the flexible time domain format F, and the second time domain format corresponds to the downlink D. Then the third time domain format corresponds to the uplink U, the sub-time domain format corresponds to the {FDU} structure, and the corresponding time unit format pattern is repeatedly transmitted with the {FUD} structure.

[0298] Example 2:

[0299] Taking the first time unit as a symbol as an example, the first time domain format corresponds to the flexible time domain format F, and the second time domain format corresponds to the downlink U. Then the third time domain format corresponds to the uplink D, and the sub-time domain format corresponds to the {FDU} structure. The corresponding time unit format pattern is repeatedly transmitted with the {FDU} structure.

[0300] Example 3:

[0301] Taking the first time unit as a symbol as an example, the first time domain format corresponds to the flexible time domain format D, and the second time domain format corresponds to the downlink F. Then the third time domain format corresponds to the uplink U, and the sub-time domain format corresponds to the {DUF} structure. The corresponding time unit format pattern is repeatedly transmitted with the {DUF} structure.

[0302] Example 4:

[0303] Taking the first time unit as a symbol as an example, the first time domain format corresponds to the flexible time domain format U, and the second time domain format corresponds to the downlink D. The third time domain format corresponds to the uplink F, and the sub-time domain format corresponds to the {UDF} structure. The corresponding time unit format pattern is repeatedly transmitted with the {UFD} structure.

[0304] Example 5:

[0305] Taking the first time unit as a symbol as an example, the first time domain format corresponds to the flexible time domain format U, and the second time domain format corresponds to the downlink F. Then the third time domain format corresponds to the uplink D, and the sub-time domain format corresponds to the {UDF} structure. The corresponding time unit format pattern is repeatedly transmitted with the {UDF} structure.

[0306] Example 2:

[0307] The terminal determines the time unit format based on predefined rules.

[0308] Furthermore, the time unit formats included in this embodiment may include one or more of the following:

[0309] The time domain type of at least one time domain unit in a specific time slot is defined based on a time unit format;

[0310] The time domain type of at least one time domain unit in a specific time slot is defined based on the N sub-time unit formats;

[0311] The following describes the specific implementation of the above-mentioned scheme through specific examples of the present invention.

[0312] Example 2-1:

[0313] Based on the above analysis, in this embodiment, the terminal determines a specific time unit format based on predefined rules. The specific time unit format can correspond to a table index one-to-one. For example, the table index corresponding to the specific time unit format can be a traditional table, such as the time unit format in Table 2 above, or a newly introduced time unit format in the reserved state of Table 2 (e.g., rows 56 to 254). Alternatively, the specific time unit format can belong to other tables and can be defined in other forms besides tables. The present invention is not limited to this.

[0314] The corresponding time unit format is based on a time domain format definition. Within the time range corresponding to the time slot, the time domain format is based on one or more of the following definitions:

[0315] a number N1 of first time units (e.g., symbols) that the first time-domain format lasts;

[0316] The first number of time units N2 of the second time domain format;

[0317] The specific time unit format definition is similar to that of Example 1-1 and will not be repeated here.

[0318] Example 2-2:

[0319] Based on the above analysis, in this embodiment, the terminal determines a specific time unit format based on predefined rules. The specific time unit format can correspond to a table index one-to-one. For example, the table index corresponding to the specific time unit format can be a traditional table, such as the time unit format in Table 2 above, or a newly introduced time unit format in the reserved state of Table 2 (e.g., rows 56 to 254). Alternatively, the specific time unit format can belong to other tables and can be defined in other forms besides tables. The present invention is not limited to this.

[0320] For a time unit format corresponding to a specific time slot, the corresponding time unit format is defined based on M sub-time domain formats. Within the time range corresponding to the time slot, the first sub-time domain format lasts for M1 first time units, the second sub-time domain format lasts for M2 first time units, ..., the i-th sub-time domain format lasts for Mi first time units, where M1 + M2 + ... MM = the number of first time units contained in the time slot.

[0321] Within the time range corresponding to the time slot, the sub-time domain format is based on one or more of the following definitions:

[0322] a number N1 of first time units (e.g., symbols) that the first time-domain format lasts;

[0323] The first number of time units N2 of the second time domain format;

[0324] The specific implementation is similar to that of Example 1-2 and will not be repeated here.
