[0104] In some embodiments, the above-mentioned semi-static signaling and dynamic signaling can be cell-level signaling or terminal-level signaling. The cell-level signaling can be signaling applied to a cell range, for example, it can be applied to all terminals in the cell, and the terminal-level signaling can be signaling applied to one or more specific terminals.

[0105] For example, the cell level signaling can include cell level semi-static signaling (e.g., TDD-UL-DL-ConfigCommon signaling), cell level dynamic signaling (e.g., Group Common DCI).

[0106] For example, the terminal level signaling can include terminal level semi-static signaling (e.g., TDD-UL-DL-ConfigDedicated signaling), terminal level dynamic signaling (e.g., terminal dedicated DCI).

[0107] In some embodiments, the network device can configure the time domain format for the terminal through static signaling (e.g., semi-static signaling) or dynamic signaling.

[0108] In some embodiments, the network device can configure the time unit format for the terminal through static signaling (e.g., semi-static signaling) or dynamic signaling.

[0109] The following is an exemplary description of the network device configuring the time unit format for the terminal by taking the network device configuring the time unit format for the terminal through downlink control information (DCI) as an example. The DCI can belong to dynamic signaling.

[0110] In some embodiments, the DCI can include DCI format 2_0, which can also be referred to as DCI 2_0. The DCI 2_0 can indicate the time unit format through the time unit format indicator (SFI) index carried by the DCI 2_0.

[0111] The DCI 2_0 can indicate the time unit format (which can also be referred to as the time division duplexing (TDD) structure of the slot) of at least one slot through the SFI-index. For example, the indicated at least one slot starts from the terminal monitoring the DCI 2_0, and the length (the number of slots) is greater than or equal to the monitoring period of the DCI 2_0. For example, the structure of the DCI 2_0 can be as follows:

[0112] The following information is sent through the DCI 2_0, where the cyclic redundancy check (CRC) is scrambled by the SFI-RNTI (Radio Network Temporary Identity):

[0113] - If the higher layer parameter slotFormatCombToAddModList is configured,

[0114] Slot Format Indicator 1, Slot Format Indicator 2, …, Slot Format Indicator N.

[0115] It can be seen that the DCI 2_0 can contain one or more SFI-indexes, and then one or more time unit formats of a specific cell can be indicated by the SFI-indexes. For example, the SFI-index can indicate an identity of a specific slot format combination in a plurality of configured slot format combinations (slotFormatCombination), and the identity corresponds to a slot format combination containing one or more time unit formats, for example, up to 256 slot formats. For example, the relevant information element (IE) of the time unit format combination is as follows:

[0116] In some embodiments, the SFI-index can also indicate the relevant configuration information of the time unit format combination, for example, as shown in Table 1 below:

[0117] Table 1

[0118] In some embodiments, the DCI 2_0 can belong to terminal-level signaling, and can be group-scheduled per UE.

[0119] In some embodiments, the DCI 2_0 can belong to cell-level signaling, and can be scheduled for terminals within the cell.

[0120] In some embodiments, the network device can configure the time domain format pattern for the terminal through semi-static signaling and / or dynamic signaling, for example, the time domain format pattern can be referred to as TDD pattern.

[0121] For example, the network device can configure the time domain format pattern for the terminal through time division duplex uplink-downlink configuration common (tdd-UL-DL-ConfigurationCommon) signaling and / or time division duplex uplink-downlink configuration specific (tdd-UL-DL-ConfigurationDedicated). The terminal can determine the time domain type of the time domain unit according to the time domain format pattern, for example, U (uplink), D (downlink), F (flexible), etc. The time domain unit includes at least one of the following: frame, subframe, slot, mini-slot, symbol.

[0122] For example, for a slot of type F, the time unit format indicated by the DCI 2_0 can be used to determine the time domain type of the symbols in the slot, for example, for a symbol of type F, the time unit format indicated by the DCI 2_0 can be used to determine the time domain type of the symbol.

[0123] For time domain units determined as U or D based on the time domain format pattern, the terminal does not expect the DCI 2_0 to indicate different types for these time domain units (for example, indicating a time domain unit of type U as type D or F, or indicating a time domain unit of type D as type U or F).

[0124] In some embodiments, the time unit format can be indicated by a row index in the list to a specific time unit format. As shown in Table 2 below, the time unit formats defined in the table can contain 1 or 2 switching points for uplink-downlink switching:

[0125] Table 2

[0126] FIG. 1B is a schematic diagram illustrating a time unit format according to an embodiment of the present disclosure.

[0127] As shown in FIG. 1B, for example, the DCI 2_0 contains N SFIs, wherein SFI #3 can indicate a time unit format combination #j for cell #i. Wherein the time unit format combination #j contains M time unit formats, the minimum value of M is 1 and the maximum value is 256.

[0128] In the M time unit formats, for example, time unit format #2 has 1 uplink-downlink switching point, specifically DDDDDDDDDDDDFU, for example, time unit format #M has 2 uplink-downlink switching points, specifically DDDDDFUDDDDDFU.

[0129] After the terminal determines the time unit format, it can determine the type of the time domain unit according to the time unit format, for example, if the slot format is the above-mentioned time unit format #2, it can be determined that the types of the first 12 symbols in the corresponding slot are D, the type of the 13th symbol is F, and the type of the 14th symbol is U.

[0130] According to an embodiment of the present disclosure, the network device can indicate the time domain format to the terminal through the indication information, and the terminal can determine the type of the time domain unit (for example, symbol) in the slot based on the time domain format, for example, uplink, downlink, flexible, etc., so that the terminal can take appropriate communication mode on each time domain unit in the subsequent communication process.

[0131] It should be noted that the terminal can determine the time domain format based on the indication information, or determine the time domain format based on a predefined rule, in which case the network device can also determine the time domain format based on the predefined rule.

[0132] For example, the protocol stipulates the time domain format, or the terminal pre-stores a correspondence between scenarios and time domain formats, so that the terminal can determine the time domain format corresponding to a specific scenario based on the correspondence when communicating in the specific scenario.

[0133] In some embodiments, the time unit format is used to indicate the time domain type corresponding to at least one symbol in a slot or a sub-slot.

[0134] For example, the time unit format is used to indicate the time domain type corresponding to at least one symbol in a slot, and the terminal can determine the time domain type corresponding to at least one symbol in the slot according to the time unit format after determining the time unit format. For example, for a specific slot, the slot format is DDDDDDDDDDDDFU, and the terminal can determine that the first 12 symbols in the slot are of type D, the 13th symbol is of type F, and the 14th symbol is of type U.

[0135] For example, the time unit format can be used to indicate the time domain type corresponding to at least one symbol in a sub-slot, in which case the time unit format can be referred to as a sub-time unit format. The terminal can determine the time domain type corresponding to at least one symbol in the sub-slot according to the sub-time unit format after determining the sub-time unit format.

[0136] The number of symbols contained in a sub-slot can be less than the number of symbols contained in a slot, for example, a sub-slot can contain 2, 7, or the like. For example, the sub-time unit format is DF, and the terminal can determine that the first symbol in the sub-slot is of type D and the second symbol is of type F.

[0137] In some embodiments, the time unit format is determined based on at least one of the following contained in the indication information:

[0138] The number of symbols of at least one time domain type;

[0139] The order of the time domain types.

[0140] In some embodiments, in the case where the order of the time domain types is fixed, for example, in the case stipulated by the protocol, the terminal only needs to determine the time domain unit corresponding to each time domain type in the period based on the number of time domain units of at least one time domain type.

[0141] It should be noted that, in some embodiments, the information about the number of symbols that at least one time domain type of the time unit format lasts, the order of the time domain types, etc. can be indicated by the indication information, or can be determined based on a predefined rule (e.g., a protocol agreement), and the disclosure does not limit this.

[0142] In some embodiments, the number of time domain units that each time domain type lasts includes at least one of

[0143] :

[0144] the number of symbols that the first time domain type lasts;

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

[0146] the number of symbols that the third time domain type lasts.

[0147] 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 downlink, and the third time domain type is uplink.

[0148] In some embodiments, in addition to the conventional time domain types D, F, and U described above, the disclosure can also extend the time domain types of the time domain units and introduce new time domain types, and the description of the three time domain types in the above embodiments can also be implemented based on the newly introduced time domain types.

[0149] For example, the new time domain type can include an SBFD type (e.g., referred to as a fourth time domain type), where the time domain unit of the SBFD type can 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.

[0150] For example, the new time domain type can include a transmission direction type (e.g., referred to as a fifth time domain type), where the time domain unit of the transmission direction type can include a time domain unit whose transmission direction is indicated by the network or a predefined rule.

[0151] The following embodiments are mainly described in the case of including the three conventional time domain types for the sake of simplifying the description and facilitating understanding.

[0152] FIG. 3 is a schematic diagram illustrating determination of a time domain type corresponding to at least one symbol in a time slot according to an embodiment of the present disclosure.

[0153] As shown in FIG. 3, the number of time domain units that each time domain type lasts includes:

[0154] the number of symbols N1 that the first time domain type lasts;

[0155] the number of symbols N2 that the second time domain type lasts.

[0156] For example, the terminal can determine a time slot to which the time unit format applies, and in the plurality of symbols included 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 belong to the third time domain type.

[0157] For example, the terminal can determine a sub-time slot to which the time unit format applies, and in this case, the time unit format can be referred to as a sub-time unit format.

[0158] wherein one time slot can include M sub-time slots, and M can be an integer greater than 1. The ith sub-time slot of the M sub-time slots lasts n i symbols, and the total number of symbols in the time slot in which the M sub-time slots are located is n M symbols, then the time domain type corresponding to at least one symbol in the time slot in which the M sub-time slots are located can also be determined based on the M sub-time slot structures corresponding to the M sub-time slots.

[0159] In the case where the sub-time unit format determined by the terminal applies to the ith sub-time slot, according to the above N1 and N2, it can be determined that in the n i symbols corresponding to the ith 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 belong to the third time domain type.

[0160] In addition, in some embodiments, in the case where a new time domain type is introduced, the time domain types are not limited to the above three time domain types. In this case, each time a new time domain type is introduced, the number of time domain units that the at least one time domain type lasts can be determined.

[0161] For example, in the case of introducing the SBFD time domain type, taking the embodiment shown in FIG. 3 as an example, there are 4 time domain types, and in addition to determining the number of symbols N1 of the first time domain type and the number of symbols N2 of the second time domain type, the terminal can also determine the number of symbols of the third time domain type, or the number of symbols of the SBFD time domain type. After determining the number of symbols of the 3 time domain types, the other symbols in the time slot structure applicable to the time slot or sub-slot belong to the 4th time domain type.

[0162] Taking the order of time domain types {D F 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-slot based on network device indication or pre-defined manner, so as to determine that the remaining time domain unit type in the specific time slot or sub-slot is F; or the network device can indicate or predefine the distribution of time domain types D, F and U time domain units in a specific time slot or sub-slot, so as to determine that the remaining time domain unit type in the specific time slot or sub-slot is SBFD.

[0163] 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 the time slot based on parameters such as the number of time domain units (such as symbols) of at least one time domain type, the order of time domain types, etc. However, the way the present disclosure determines the time domain type corresponding to at least one symbol in the time slot is not limited thereto. For example, the network device can directly indicate the time domain type of each time domain unit. For example, for 10 time domain units, 20 bits can be used to indicate the time domain type of the 10 time domain units, and 2 bits correspond 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); and the value of 2 bits is 11, which can be reserved or used to indicate other time domain types, such as the SBFD type in the above embodiment.

[0164] For example, the time domain format is directly determined based on a pre-defined manner. For example, the time domain format corresponding to a specific index (e.g., 101) is DDDDFUUUUUUU, and the terminal determines that the time domain format corresponding to the index 101 is DDDDFUUUUUUU.

[0165] In some embodiments, the time unit format is determined based on a time unit format indication index included in the indication information.

[0166] 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 time unit format.

[0167] For example, the mapping relationship can be represented by a table or in other ways, and the present disclosure does not limit this.

[0168] For example, in the case of representing the mapping relationship by a table, the table can be a traditional table, such as Table 2 described above; or the table can be a table formed by introducing a new time domain type order time unit format on the basis of a traditional table, for example, setting the new time domain type order time unit format in at least one of the 56th to 254th rows; or the table can not contain part or all of the time unit formats in the traditional table.

[0169] For example, the indication information sent by the network device to the terminal can contain an index, such as SFI-index, and the terminal can determine the time unit format corresponding to the SFI-index in the mapping relationship as the time unit format indicated by the network device.

[0170] In some embodiments, the mapping relationship is defined based on at least one of the following:

[0171] The number of symbols that at least one time domain type lasts;

[0172] The order of time domain types.

[0173] In some embodiments, the mapping relationship can be determined based on the number of symbols that at least one time domain type lasts, for example, the mapping relationship can contain an index and a time unit format, and the time unit format can be determined based on the number of symbols that at least one time domain type lasts. The relevant determination method can refer to the example shown in FIG. 3, and the present disclosure will not be repeated here.

[0174] In this case, the mapping relationship can not indicate the time domain type for each of the 14 symbols as shown in Table 2, but can only indicate the time domain type of part of the symbols, and the terminal can also determine the time domain type of each symbol.

[0175] It should be noted that in addition to the above-mentioned determination based on the index or the number of symbols that at least one time domain type lasts, the time unit format can also be determined based on a predefined rule (such as a protocol agreement) or a network device indication of the type of each symbol, for example, the network device can indicate the time domain type of each of the 14 symbols in the time slot, and the terminal can determine the time domain type of each of the 14 symbols accordingly.

[0176] In some embodiments, the mapping relationship can be determined based on not only the number of symbols that the at least one time domain type lasts, but also the order of the time domain types. For example, the mapping relationship can include an index and a time unit format, where the time unit format can be determined based on the number of symbols that the at least one time domain type lasts and the order of the time domain types.

[0177] In addition, in some embodiments, the slot format can also be determined based on the number of symbols that the at least one time domain type lasts and the order of the time domain types.

[0178] It should be noted that, in some embodiments, the number of symbols that the at least one time domain type lasts, the order of the time domain types, and the like, which define the mapping relationship, can be indicated by the network device, or can be determined based on a pre-defined rule (for example, a protocol agreement), and the present disclosure does not limit this.

[0179] In some embodiments, as the communication technology develops, in order to meet different communication needs, content related to scenarios is introduced, where the scenario can also be referred to as a function set.

[0180] However, since the communication needs of the terminal and the network device can be different in different scenarios, in the above scheme in which the network device indicates the time domain format to the terminal, since the scenario to which the time domain format applies is not explicitly specified, 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.

[0181] In some embodiments, the scenario includes at least one of the following:

[0182] Subband Full Duplex (SBFD);

[0183] Communication and sensing (for example, sensing can be translated as sensing);

[0184] Time Division Duplex (TDD);

[0185] Power saving (for example, network power saving, terminal power saving);

[0186] Artificial Intelligence (AI).

[0187] Among them, the TDD scenario belongs to the traditional communication scenario, and the present disclosure will not repeat it here. The following will illustrate several other scenarios through several embodiments.

[0188] In some embodiments, in the 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 resource 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 resource outside the uplink subband.

[0189] Alternatively, in the SBFD scenario, the network device can configure a downlink subband (DL subband) in an uplink time domain unit or a flexible time domain unit, so that in the frequency domain resource 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 resource outside the downlink subband.

[0190] In some embodiments, in the sensing scenario, Integrated Sensing and Communication (ISAC) can be implemented in the communication system, the functions of communication and sensing can be complementary to each other, and can be applied to scenarios such as high-precision positioning tracking, synchronous imaging, and map construction. In the sensing scenario, the time domain unit needs to be reasonably configured to realize the functions of communication and sensing.

[0191] In some embodiments, through energy saving technology, energy saving of the network device and / or energy saving of the terminal can be realized, which is beneficial to reduce the energy consumption in the communication process. In order to meet the energy saving needs, the time domain unit in the communication process needs to be reasonably configured.

[0192] In some embodiments, communication can be combined with AI to enhance the automation and skillfulness of network operation, and to enhance the functions and characteristics of the network. For example, the monitoring results of various monitoring operations (such as the results of minimizing road testing, channel state information, etc.) can be predicted based on the model determined by AI, and the demodulation results of data modulated by each modulation mode can be predicted based on the model determined by AI. The combination of communication and AI is not limited to the above examples, and the present disclosure does not limit this. In the case of combining communication with AI, the time domain unit also needs to be reasonably configured.

[0193] As can be seen, in the above different scenarios, there are respective needs for configuration of the time domain unit, so that the most suitable time domain format in each scenario is different.

[0194] 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 containing downlink time slots and uplink time slots, not containing flexible time slots, the time domain format can be DDDUU, DDUUU, and the like, that is, the time slot of the D type is located before the time slot of the U type. If there are flexible time slots in the 5 time slots, the time domain format can be DDFUU, DDDFU, and the like, that is, the time slot of the F type is located after the time slot of the D type and before the time slot of the U type.

[0195] This way of determining the time domain format in a fixed order will severely limit the scenarios in which the time unit format is used. For example, in a TDD scenario, it is mainly considered to receive downlink information first and then feed back according to the reception situation, so the time domain format determined based on the order of {DFU} can be applicable to the TDD scenario, but for other scenarios, the time domain format determined based on the order of {DFU} is not necessarily applicable.

[0196] For example, for an SBFD scenario, since the network device configures an uplink subband in a downlink time domain unit or a flexible time domain unit, or configures a downlink subband in an uplink time domain unit or a flexible time domain unit, on these time domain units configured with subbands, the network device and / or the terminal can perform uplink communication and downlink communication, and 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 back.

[0197] Therefore, the present disclosure further proposes, for the above problems, determining the time domain unit corresponding to at least one time domain type, not only based on the number of time domain units that at least one time domain type lasts, but also based on the order of the time domain type.

[0198] In some embodiments, the order of the time domain type includes at least one of the following orders, or a cycle of any of the following orders:

[0199] uplink, that is, {U};

[0200] downlink, that is, {D};

[0201] flexible, that is, {F};

[0202] uplink and downlink, that is, {UD};

[0203] uplink and flexible, that is, {UF};

[0204] uplink, flexible, and downlink, that is, {UFD};

[0205] uplink, downlink, and flexible, that is, {UDF};

[0206] flexible and uplink, that is, {FU};

[0207] Flexible, downlink, i.e. {FD};

[0208] Flexible, uplink, downlink, i.e. {FUD};

[0209] Flexible, downlink, uplink, i.e. {FDU};

[0210] Downlink, uplink, i.e. {DF};

[0211] Downlink, flexible, i.e. {DU};

[0212] Downlink, flexible, uplink, i.e. {DFU};

[0213] Downlink, uplink, flexible, i.e. {DUF}.

[0214] In some embodiments, the order of time domain types includes one of the above-mentioned orders, for example, the included order is {DFU}, and taking 14 symbols as an example, the time domain format may, for example, be DDDDDDDDDDDFU, DDDDDDDDDFFUUU, etc.

[0215] In some embodiments, the order of time domain types includes a cycle of one of the above-mentioned orders, for example, the included order is {DFU}, and taking 14 symbols as an example, the time domain format may, for example, be DDDDDFUDDDDDFU, DDDFUDFUDFUDFU, etc.

[0216] In some embodiments, the order of time domain types includes a combination of multiple of the above-mentioned orders, for example, the included order is {DFU} and {FD}, and taking 14 symbols as an example, the time domain format may, for example, be DDDDDFUFFFDDDD, DDDFFUUFFFFFDD, etc.

[0217] In some embodiments, the order of time domain types includes one of the above-mentioned orders, for example, the included order is {DFU}, and taking 14 symbols as an example, the time domain format may, for example, be DDDDDDDDDDDDFU, DDDDDDDDDFFUUU, etc.

[0218] It should be noted that the order of time domain types is not limited to the above-mentioned several determination methods, for example, the order of time domain types may also include a cycle of multiple of the above-mentioned orders, or include a cycle of at least one order and a combination of multiple orders, and the present disclosure does not limit this.

[0219] In this embodiment, the order of the time domain types is no longer fixed as {UFD}, but can be flexibly configured by the network device. For example, the network device can configure different orders of time domain types for different scenarios, so that the time domain format determined by the terminal based on the order of the time domain types (the time domain unit corresponding to each time domain type) can be suitable for the corresponding scenario, which is beneficial to ensure that the terminal has relatively good communication quality when communicating based on the determined time domain format in the corresponding scenario.

[0220] For example, in the embodiment shown in FIG. 3, if the number of time domain units that at least one time domain type lasts is determined based on the fixed order of time domain types {UFD}, the first time domain type is fixed as U, the second time domain type is fixed as D, and the third time domain type is fixed as F, which greatly limits the expansion of the time domain format.

[0221] According to the present embodiment, when determining the number of time domain units that at least one time domain type lasts, the terminal can consider the order of the time domain types configured by the network device. For example, the order of the time domain types is {DFU}, the first time domain type is D, the second time domain type is U, and the third time domain type is F, thereby realizing the expansion of the time domain format so that the time domain format can be suitable for more scenarios.

[0222] Similarly, in the case of determining the mapping relationship based on the time domain type, the time domain format in the mapping relationship can also be expanded so that the time domain format can be suitable for more scenarios. For example, based on the traditional mapping relationship shown in Table 2, more time unit formats can be introduced by considering different orders of time domain types, such as UUUUUUUUUUUFD, UUUDDDFUUUDDDF, etc.

[0223] It should be noted that in some embodiments, in addition to the traditional time domain types D, F, and U, the present disclosure can also expand the time domain types of the time domain units, introduce new time domain types, such as the SFBD type and the transmission direction type described above. In the case of introducing new time domain types, the order of the time domain types described above can be further expanded, for example, the new time domain type is added before or after any traditional time domain type (such as the above D, F, U, etc.), and the present disclosure does not limit this.

[0224] The communication method related to the embodiments of the present disclosure can include at least one of steps S201-S202. For example, step S201 can be implemented as an independent embodiment, step S202 can be implemented as an independent embodiment, and steps S201+S202 can be implemented as an independent embodiment, but are not limited thereto.

[0225] In some embodiments, steps S201 and S202 can be exchanged in order or performed simultaneously.

[0226] In some embodiments, step S201 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0227] In some embodiments, step S202 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0228] In some embodiments, other optional implementations described before or after the description corresponding to FIG. 2 can be referred to.

[0229] In a first aspect, embodiments of the present disclosure provide an information receiving method. FIG. 4 is a schematic flowchart of an information receiving method according to an embodiment of the present disclosure. The information receiving method shown in this embodiment can be performed by a terminal.

[0230] As shown in FIG. 4, the information receiving method can include the following steps:

[0231] In step S401, receiving indication information sent by a network device, wherein the indication information is used to indicate at least one time slot and / or time unit format of a sub-slot in at least one time slot.

[0232] It should be noted that the embodiment shown in FIG. 4 can be independently implemented, or can be implemented in combination with at least one other embodiment of the present disclosure. The specific implementation can be selected as needed, and the present disclosure does not limit it.
