[0098] As illustrated in FIG. 2, the information receiving method can include the following steps.

[0099] In step S201, the network device sends first indication information to the terminal.

[0100] In some embodiments, the first indication information is used to indicate information of the time domain pattern.

[0101] In step S202, the terminal determines the time domain pattern according to the first indication information.

[0102] In some embodiments, the first indication information sent by the network device to the terminal can be carried in semi-static signaling or dynamic signaling.

[0103] For example, the semi-static signaling can include Radio Resource Control (RRC) signaling and System Information Block (SIB), and the dynamic signaling can include Downlink Control Information (DCI).

[0104] In addition, the signaling for configuring the time domain pattern can also include a Media Access Control Control Element (MAC CE). The MAC CE can be classified as semi-static signaling or dynamic signaling, and the present disclosure does not limit this.

[0105] For example, the SIB can carry TDD-UL-DL-ConfigCommon signaling, and the RRC signaling can include TDD-UL-DL-Configdedicated signaling.

[0106] 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, applied to all terminals in the cell, and the terminal-level signaling can be signaling applied to one or more specific terminals.

[0107] For example, the cell-level signaling can include cell-level semi-static signaling (such as TDD-UL-DL-ConfigCommon signaling) and cell-level dynamic signaling (such as Group Common DCI).

[0108] For example, the terminal-level signaling can include terminal-level semi-static signaling (such as TDD-UL-DL-ConfigDedicated signaling) and terminal-level dynamic signaling (such as terminal-specific DCI).

[0109] In some embodiments, the network device can configure a time division duplex pattern (TDD pattern) for the terminal through static signaling (for example, semi-static signaling) or dynamic signaling, where the TDD pattern can also be referred to as a time domain format pattern.

[0110] For example, the time domain format pattern can be determined based on at least one of the following: the period of the time domain format pattern, the number of downlink time domain units in the period, the number of uplink time domain units in the period, and a reference subcarrier spacing (SCS).

[0111] In some embodiments, taking the TDD-UL-DL-ConfigCommon signaling as an example, the signaling can configure at least one time domain format pattern for the terminal, and for a specific time domain format pattern, the following parameters in the configuration can be used for determination: a reference SCS, a period P, the number of downlink time domain units, and the number of uplink time domain units, where the time domain unit includes at least one of the following: a frame, a subframe, a slot, a mini-slot, and a symbol, where the symbol can be an OFDM (Orthogonal Frequency Division Multiplexing) symbol.

[0112] The reference SCS and the period P can be used to determine the total number S of time domain units in the period, and taking the time domain unit as an example, the first d slot slots in the S slots are all first time domain type slots, the last one of the first d slot slots in the first d sym slots is followed by the first d slot slots in the S slots are all second time domain type slots, the first one of the last u slot slots is followed by the last u sym slots in the first u slot slots are all second time domain type symbols. In addition, other slots and symbols in the period are all third time domain type slots and symbols.

[0113] FIG. 3A is a schematic diagram of a time domain format pattern according to an embodiment of the present disclosure.

[0114] For example, S = 10, d slot = 2, d sym = 0, u slot = 2, u sym = 0, the time domain format pattern can be as shown in FIG. 3A.

[0115] In the example shown in FIG. 3A, one time domain format pattern is configured for the terminal by the network device, and in some embodiments, the number of time domain format patterns configured for the terminal by the network device is not limited to one, but can also be two or more.

[0116] FIG. 3B is a schematic diagram of another time domain format pattern, according to an embodiment of the present disclosure.

[0117] As shown in FIG. 3B, the network device configures two time domain format patterns Pattern#1 and Pattern#2 for the terminal, where the period of Pattern#1 is P1, the period of Pattern#2 is P2, Pattern#1 is specifically DDF, that is, in 3 slots, the first 2 slots are downlink slots, and the third slot is a flexible slot, and Pattern#2 is specifically DF, that is, in 2 slots, the first slot is a downlink slot, and the second slot is a flexible slot. The two time domain format patterns are cyclic in the time domain, so for the two patterns, the period is P1+P2.

[0118] In some embodiments, taking the TDD-UL-DL-ConfigDedicated signaling as an example, the time domain format pattern indicated by the signaling can be applied to the time domain unit whose time domain type is F (flexible) indicated by the TDD-UL-DL-ConfigCommon signaling.

[0119] For example, the TDD-UL-DL-ConfigDedicated signaling can be configured with the slot configuration period configured by the TDD-UL-DL-ConfigCommon signaling as the period (which can be the period of one time domain format pattern or the sum of the periods of multiple time domain format patterns), and with the slot and / or symbol as the granularity, to reconfigure the time domain unit whose time domain type is F configured by the TDD-UL-DL-ConfigCommon signaling, for example, it can be reconfigured as {all D, all U, DFU}.

[0120] Where reconfiguration as all D means that the time domain unit of type F is indicated as a time domain unit of type D (downlink), reconfiguration as all U means that the time domain unit of type F is indicated as a time domain unit of type U (uplink), and reconfiguration as DFU means that the time domain unit of type F is indicated as a time domain unit of type D and / or F and / or U according to the time domain type order of DFU.

[0121] In some embodiments, the configuration information related to TDD-UL-DL-ConfigDedicated can further include other parameters for the terminal to determine the time domain pattern, for example, the other parameters can be shown in Table 1 below:

[0122] Table 1

[0123] According to an embodiment of the present disclosure, the network device can indicate the time domain pattern to the terminal through the indication information, and the terminal can determine the type of time domain unit in the time domain resource range based on the time domain pattern, such as uplink, downlink, flexible, etc., so that the terminal can communicate in an appropriate manner on each time domain unit in the subsequent communication process.

[0124] It should be noted that the terminal can determine the time domain pattern based on the first indication information, or determine the time domain pattern based on a predefined rule, in which case the network device can also determine the time domain pattern based on the predefined rule.

[0125] For example, the protocol stipulates the time domain pattern, or the terminal pre-stores the correspondence between the scene and the time domain pattern, so that the terminal can determine the time domain pattern corresponding to the specific scene based on the correspondence when communicating in the specific scene.

[0126] The following embodiments mainly illustrate the technical solutions of the present disclosure in the case where the terminal determines the time domain pattern based on the first indication information.

[0127] In some embodiments, the number of time domain patterns satisfies at least one of the following: less than or equal to 2; greater than 2.

[0128] For example, the number of time domain patterns contained in at least one time domain pattern can be less than or equal to 2.

[0129] Considering that the traditional TTD time slot format pattern configuration mechanism can configure at most two time domain patterns, in order to follow the traditional mechanism or modify the traditional mechanism as little as possible, the number of time domain patterns configured by the network device for the terminal in the embodiment is less than or equal to 2.

[0130] For example, the number of time domain patterns contained in at least one time domain pattern can be greater than 2.

[0131] Considering that one or more scenes (or referred to as feature sets) are introduced, and the scene corresponds to the time domain pattern, in order to enable the terminal to support the time domain pattern of different scenes, the number of time domain patterns configured by the network device for the terminal in the embodiment can be greater than 2.

[0132] In some embodiments, the information of the time domain pattern is used to indicate at least one of the following:

[0133] a period of the time-domain pattern;

[0134] a time-domain unit corresponding to each time-domain type in the period.

[0135] In some embodiments, the period includes a plurality of sub-periods.

[0136] In some embodiments, the time-domain pattern includes a plurality of sub-time-domain patterns.

[0137] In some embodiments, a period of a sub-time-domain pattern is a sub-period, and the period includes a plurality of sub-periods of the plurality of time-domain patterns.

[0138] For example, in a case where the network device configures the terminal with a plurality of time-domain patterns, each time-domain pattern can be referred to as a sub-time-domain pattern, and in this case, the period can include a plurality of sub-periods, and the sub-period is a period of the sub-time-domain pattern. For example, in the example shown in FIG. 3B, Pattern#1 and Pattern#2 can be referred to as sub-time-domain patterns, and the period P1 of Pattern#1 and the period P2 of Pattern#2 can be referred to as sub-periods.

[0139] In some embodiments, in a case where the terminal is configured with a plurality of time-domain patterns, the plurality of time-domain patterns can be periodically repeated based on a time-domain pattern configuration period.

[0140] Regarding the time-domain pattern configuration period, for example, the TDD configuration period includes a plurality of time-domain patterns, and the duration of the time-domain pattern configuration period is equal to the sum of the periods of each time-domain pattern.

[0141] For example, in a case where the terminal is configured with three time-domain patterns, if the periods of the three time-domain patterns are P, P1, and P2, respectively, the duration of the TDD configuration period is equal to P+P1+P2.

[0142] In some embodiments, the time-domain pattern configuration period can be an integer multiple of N, that is, N / time-domain pattern configuration period is an integer, and N is determined based on an indication of the network device or determined based on a predetermined rule, which is not limited by the present disclosure. For example, in a case where the terminal is configured with two time-domain patterns, N=20 ms, and for example, in a case where the terminal is configured with three time-domain patterns, N=30 ms or N=40 ms.

[0143] Exemplarily, a first time domain unit of every N / N1 time domain units can be as a starting position of a period, or a first time domain unit of every N time domain units can be as a starting position of a period, for example, a first time domain unit of every F frames is as a starting position of a period, exemplarily, a first OFDM symbol of every F frames is as a starting position of a period. Wherein, F = N / N1 ms. Wherein, N1 is a quantity of time domain units occupied by one OFDM frame, taking N as an example based on OFDM slot measurement, N1 corresponds to 10 at 15 kHz;

[0144] Exemplarily, a first time domain unit of every (N / periodicity of the time domain pattern configuration) configuration periods can be as a starting position of a period, for example, a first time domain unit of every F of the configuration periods is as a starting position of a period, exemplarily, a first OFDM symbol of every F of the configuration periods is as a starting position of a period. Wherein, F = N / N1 ms. Wherein, N1 is a duration of a TDD configuration period, taking the above configuration of 3 slot format patterns as an example, N1 = P+P1+P2.

[0145] The following embodiments are mainly described for time domain units corresponding to each time domain type in a period for the convenience of examples. In some embodiments, the description of the subsequent embodiments can also be applied to examples of time domain units corresponding to each time domain type in a sub-period, for example, the period in the subsequent embodiments is replaced by a sub-period, and the time domain format pattern is replaced by a sub-time domain format pattern, which is also applicable.

[0146] In some embodiments, the time domain units corresponding to each time domain type in a period are determined based on at least one of the following:

[0147] A quantity of time domain units that at least one time domain type lasts;

[0148] An order of the time domain types.

[0149] In some embodiments, in the case that the order of the time domain types is fixed, for example, in the case that it is agreed by a protocol, the terminal only needs to determine the time domain units corresponding to each time domain type in a period based on the quantity of time domain units that at least one time domain type lasts.

[0150] In some embodiments, in the case that the first indication information is carried in cell-level signaling, the quantity of time domain units that at least one time domain type lasts includes at least one of the following:

[0151] A quantity of first time domain units that a first time domain type lasts;

[0152] A quantity of second time domain units that the first time domain type lasts;

[0153] a number of first time domain units in which the second time domain type lasts;

[0154] a number of second time domain units in which the second time domain type lasts;

[0155] a number of first time domain units in which the third time domain type lasts;

[0156] a number of second time domain units in which the third time domain type lasts.

[0157] In some embodiments, taking the TDD-UL-DL-ConfigCommon signaling as an example, the time domain format pattern indicated by the TDD-UL-DL-ConfigCommon signaling is generally applicable to indicating the time domain type of the first time domain unit, and further applicable to indicating the time domain type of the second time domain unit.

[0158] wherein the first time domain unit and the second time domain unit are different time domain units, and the time domain range of the first time domain unit is greater than the time domain range of the second time domain unit, for example, the first time domain unit is a slot, and the second time domain unit is a symbol.

[0159] Based on the above analysis, the time domain format pattern indicated by the cell-level signaling (for example, the TDD-UL-DL-ConfigCommon signaling) can be applicable to indicating the time domain type of the first time domain unit and the second time domain unit, so when the first indication information is carried by the cell-level signaling, that is, when the time domain format pattern is indicated by the cell-level signaling, the number of time domain units in which at least one time domain type lasts can be determined based on the number of first time domain units in which at least one time domain type lasts and the number of second time domain units.

[0160] Of course, the time domain format pattern indicated by the cell-level signaling can also be applicable to indicating the time domain type of only the first time domain unit or the second time domain unit, so when the first indication information is carried by the cell-level signaling, that is, when the time domain format pattern is indicated by the cell-level signaling, the number of time domain units in which at least one time domain type lasts can be determined based on the number of first time domain units in which at least one time domain type lasts or the number of second time domain units.

[0161] In some embodiments, the first time domain type, the second time domain type, and the third time domain type correspond to one of uplink (U), flexible (F), and downlink (D), respectively.

[0162] In addition, 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 type of the time domain unit and introduce new time domain types, so the description of the three time domain types in the above embodiments can also be implemented based on the newly introduced time domain types.

[0163] For example, the new time domain type can include a SBFD type (for example, referred to as a fourth time domain type), wherein 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.

[0164] For example, the new time domain type can include a transmission direction type (for example, referred to as a fifth time domain type), wherein the time domain unit of the transmission direction type can include a time domain unit in which a network indication or a predefined rule defines a transmission direction.

[0165] The following embodiments are mainly exemplarily described in the case where the time domain types include the conventional three time domain types for the purpose of simplifying the description and facilitating understanding.

[0166] FIG. 4A is a schematic diagram illustrating determination of time domain units corresponding to each time domain type in a period according to an embodiment of the present disclosure.

[0167] As shown in FIG. 4A, the number of time domain units in which at least one time domain type indicated by the information of the time domain pattern lasts includes:

[0168] the number N1 of first time domain units in which the first time domain type lasts;

[0169] the number N2 of second time domain units in which the first time domain type lasts;

[0170] the number N3 of first time domain units in which the second time domain type lasts;

[0171] the number N4 of second time domain units in which the second time domain type lasts.

[0172] The terminal can determine that, in the period of the time domain pattern, the first N1 first time domain units are the first time domain units of the first time domain type, and the first N2 second time domain units in the first time domain unit next to the last first time domain unit of the first time domain type in the first N1 time slots are all the second time domain units of the first time domain type. In the period of the time domain pattern, the last N3 first time domain units are all the first time domain units of the second time domain type, and the last N4 second time domain units in the first time domain unit next to the first first time domain unit of the last N3 first time domain units are all the second time domain units of the second time domain type. In addition, in the period of the time domain pattern, the other first time domain units and second time domain units belong to the third time domain type.

[0173] It should be noted that the first time domain unit and the second time domain unit in the above embodiments can be a time domain unit such as a frame, a subframe, a slot, a symbol, etc. For example, the first time domain unit can be a slot, and the second time domain unit can be a symbol.

[0174] In some embodiments, when the first indication information is carried in the terminal-level signaling, the number of time domain units in which the at least one time domain type lasts includes at least one of the following:

[0175] the number of second time domain units in which the first time domain type lasts;

[0176] the number of second time domain units in which the second time domain type lasts;

[0177] the number of second time domain units in which the third time domain type lasts.

[0178] In some embodiments, taking the terminal-level signaling including TDD-UL-DL-ConfigDedicated signaling as an example, the time domain format pattern indicated by the TDD-UL-DL-ConfigDedicated signaling generally indicates the time domain type of the second time domain unit. For example, in the foregoing embodiments, the time domain type of the slot configured by the TDD-UL-DL-ConfigCommon signaling can be reconfigured.

[0179] Based on the above analysis, it can be known that the time domain format pattern indicated by the terminal-level signaling (for example, the TDD-UL-DL-ConfigDedicated signaling) can be suitable for indicating the time domain type of the second time domain unit, and therefore, when the first indication information is carried by the cell-level signaling, that is, when the time domain format pattern is indicated by the cell-level signaling, the number of time domain units in which the at least one time domain type lasts can be determined based on the number of second time domain units in which the at least one time domain type lasts.

[0180] FIG. 4B is a schematic diagram illustrating another determination of time domain units corresponding to each time domain type in a period according to an embodiment of the present disclosure.

[0181] As shown in FIG. 4B, the number of time domain units in which the at least one time domain type lasts, which is indicated by the information of the time domain format pattern, includes:

[0182] the number N2 of second time domain units in which the first time domain type lasts;

[0183] the number N4 of second time domain units in which the second time domain type lasts.

[0184] The terminal can determine that in a specific first time domain unit (for example, a time domain unit of time domain type F), the first N2 second time domain units are all second time domain units of the first time domain type, and the last N4 second time domain units are all second time domain units of the second time domain type. In addition, in the specific first time domain unit, the other second time domain units belong to the third time domain type.

[0185] It should be noted that the first time domain unit and the second time domain unit in the above embodiments can be a time domain unit such as a frame, a subframe, a slot, a symbol, etc. For example, the second time domain unit can be a symbol.

[0186] In addition, in some embodiments, in the case of introducing a new time domain type, the time domain type is not limited to the above three time domain types. For example, in this case, each time a new time domain type is introduced, the number of time domain units of at least one time domain type can be determined. The number of time domain units of one time domain type can be determined.

[0187] For example, in the case of introducing the SBFD time domain type, taking the embodiment shown in FIG. 4B as an example, there are four time domain types, and in addition to determining the number N2 of second time domain units of the first time domain type and the number N4 of second time domain units of the second time domain type, the terminal can also determine the number of second time domain units of the third time domain type, or determine the number of second time domain units of the SBFD time domain type. After determining the number of second time domain units of three time domain types, in a specific first time domain unit, the other second time domain units belong to the fourth time domain type.

[0188] For example, in the case of introducing the SBFD time domain type, taking the embodiment shown in FIG. 4B as an example, there are four time domain types, and in addition to determining the number N2 of second time domain units of the first time domain type and the number N4 of second time domain units of the second time domain type, the terminal can also determine the number of second time domain units of the third time domain type, or determine the number of second time domain units of the SBFD time domain type. After determining the number of second time domain units of three time domain types, in a specific first time domain unit, the other second time domain units belong to the fourth time domain type.

[0189] It should be noted that in the above implementation, the disclosure mainly determines the time domain unit corresponding to each time domain type in the period based on parameters such as the number of time domain units in which at least one time domain type lasts, the order of the time domain types, and the like. However, the manner in which the disclosure determines the time domain unit corresponding to each time domain type in the period 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, the time domain types of the 10 time domain units can be indicated by 20 bits. Each 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 a reserved bit or used to indicate other time domain types, such as the SBFD type in the above embodiment.

[0190] In some embodiments, the time domain format pattern is mainly defined based on a conventional TDD, and the basic logic is to periodically repeat based on one time domain format pattern or two time domain format patterns. The time domain format pattern is mainly configured in the order of {DFU}, where D represents that the time domain unit is a downlink time domain unit, F represents that the time domain unit is a flexible time domain unit, and U represents that the time domain unit is an uplink time domain unit. That is, in at least one time domain unit corresponding to the time domain format pattern, if there is a downlink time domain unit, the downlink time domain unit is located at the most front position in the time domain, if there is a flexible time domain unit, the flexible time domain unit is located at the second position in the time domain, and if there is a downlink time domain unit, the downlink time domain unit is located at the last position in the time domain.

[0191] 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.

[0192] 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 pattern to the terminal, since the scenario to which the time domain format pattern applies is not explicitly indicated, the terminal will use the same time domain format pattern for communication in each scenario, which is difficult to meet the communication needs in different scenarios.

[0193] In some embodiments, the scenario includes at least one of the following:

[0194] Subband Full Duplex (SBFD);

[0195] Communication and sensing (for example, sensing can be translated as sensing);

[0196] Time Division Duplexing (TDD);

[0197] Power saving, such as network power saving, terminal power saving;

[0198] Artificial Intelligence (AI).

[0199] Among them, the TDD scenario belongs to the traditional communication scenario, and the present disclosure will not be described hereinafter. The following will illustrate several other scenarios through several embodiments.

[0200] In some embodiments, in the SBFD scenario, the network device can configure an uplink subband (UL subband) in the downlink time domain unit or the flexible time domain unit, so that in the frequency domain resource corresponding to the downlink time domain unit or the flexible time domain unit, both uplink communication within the uplink subband and downlink communication in the frequency domain resource outside the uplink subband can be performed.

[0201] 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 resource corresponding to the uplink time domain unit or the flexible time domain unit, both downlink communication within the downlink subband and uplink communication in the frequency domain resource outside the downlink subband can be performed.

[0202] In some embodiments, in the sensing scenario, Integrated Sensing and Communication (ISAC) can be implemented in the communication system, and the functions of communication and sensing can be complementary to each other, which 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.

[0203] In some embodiments, through the power saving technology, the power saving of the network device and / or the power saving of the terminal can be realized, which is conducive to reducing the energy consumption in the communication process. In order to meet the needs of power saving, the time domain unit in the communication process needs to be reasonably configured.

[0204] In some embodiments, the communication can be combined with AI to enhance the automation and skillfulness of network operation, while enhancing the functions and features of network expertise. For example, the monitoring results of various monitoring operations (such as minimizing the results of road testing, channel state information, etc.) can be predicted based on the AI-determined model, and the demodulation results corresponding to the data modulated by each modulation mode can be predicted based on the AI-determined model. 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.

[0205] As can be seen, in the above different scenarios, there are respective needs for the configuration of the time domain unit, which will cause the most suitable time domain format pattern to be different in each scenario.

[0206] In some embodiments, if the time domain format pattern 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, without containing flexible time slots, the time domain format pattern can be DDDUU, DDUUU, etc., that is, the time slots of type D are located before the time slots of type U. If there are flexible time slots in the 5 time slots, the time domain format pattern can be DDFUU, DDDFU, etc., that is, the time slots of type F are located after the time slots of type D and before the time slots of type U.

[0207] This way of determining the time domain format pattern according to a fixed order will severely limit the scenarios in which the time slot format pattern is used. For example, in a TDD scenario, the main consideration is to receive downlink information first and then feed back according to the reception, so the time domain format pattern determined based on the order of {DFU} can be applicable to the TDD scenario, but for other scenarios, the time domain format pattern determined based on the order of {DFU} may not necessarily be applicable.

[0208] For example, for an SBFD scenario, since the network device configures uplink subbands in the downlink time domain unit or the flexible time domain unit, or configures downlink subbands in the uplink time domain unit or the flexible time domain unit, on these time domain units with subbands, the network device and / or the terminal can perform both uplink communication and downlink communication, so 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.

[0209] Therefore, the present disclosure further proposes, for the above problem, that the time domain unit corresponding to each time domain type in the determination period is determined not only based on the number of time domain units of at least one time domain type, but also based on the order of the time domain types.

[0210] The order of the time domain types includes at least one of the following:

[0211] Uplink, namely {U};

[0212] Downlink, i.e., {D};

[0213] Flexible, i.e., {F};

[0214] Uplink, downlink, i.e., {UD};

[0215] Uplink, flexible, i.e., {UF};

[0216] Uplink, flexible, downlink, i.e., {UFD};

[0217] Uplink, downlink, flexible, i.e., {UDF};

[0218] Flexible, uplink, i.e., {FU};

[0219] Flexible, downlink, i.e., {FD};

[0220] Flexible, uplink, downlink, i.e., {FUD};

[0221] Flexible, downlink, uplink, i.e., {FDU};

[0222] Downlink, uplink, i.e., {DF};

[0223] Downlink, flexible, i.e., {DU};

[0224] Downlink, flexible, uplink, i.e., {DFU};

[0225] Downlink, uplink, flexible, i.e., {DUF}.

[0226] 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 pattern 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 conducive to ensuring that the terminal has relatively good communication quality when communicating based on the determined time domain format pattern in the corresponding scenario.

[0227] For example, in the embodiments shown in FIGS. 4A and 4B, if the number of time domain units in which 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 pattern.

[0228] According to the embodiment, when determining the number of time domain units of at least one time domain type, 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 expanding the time domain format pattern, so that the time domain format pattern can be applied to more scenarios.

[0229] It should be noted that in some embodiments, in addition to the conventional time domain types D, F, and U, the 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 conventional time domain type (for example, the above D, F, U, etc.), and the disclosure does not limit this.

[0230] The communication method related to the embodiments of the 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.

[0231] In some embodiments, steps S201 and S202 can be exchanged in order or performed simultaneously.

[0232] In some embodiments, step S201 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0233] In some embodiments, step S202 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0234] In some embodiments, other optional implementations described before or after the description corresponding to FIG. 2 can be referred to.

[0235] In a first aspect, the embodiments of the disclosure propose an information receiving method.

[0267] The technical solutions of the present disclosure will be further illustrated by several embodiments.

[0268] Embodiment 1:

[0269] The terminal determines the period of the corresponding time domain format pattern based on the cell-level time slot format pattern configuration signaling. Further, the configuration mode contained in the present embodiment can include one or more of the following:

[0270] based on at least one slot format pattern periodicity configuration;

[0271] based on at least one slot format pattern periodicity configuration, the periodicity contains at least one sub-periodicity within the periodicity;

[0272] based on at least one slot format pattern periodicity configuration, the slot format pattern contains at least one sub-slot format pattern;

[0273] Embodiment 1-1:

[0274] In this embodiment, the terminal determines the time domain format pattern information based on one or more of the following configuration information.

[0275] (1) first slot format pattern:

[0276] The terminal determines the time domain format pattern information based on at least one first slot format pattern configured by the network device.

[0277] Exemplarily, in order to follow the legacy TDD signaling configuration mechanism as much as possible, the maximum number of first slot format patterns that the terminal can be configured for a specific cell is 2.

[0278] Exemplarily, considering the reference of more feature sets, and the slot format patterns required by different feature sets can be different, accordingly, the maximum number of first slot format patterns that the terminal can be configured for a specific cell is M, M is determined based on signaling indication or predefinition, and M>2, exemplarily, M=3, or M=4.

[0279] (2) first periodicity corresponding to the first slot format pattern:

[0280] For example, the duration of the first periodicity is equal to the duration of the first slot format pattern.

[0281] Exemplarily, under the condition that the terminal is configured with multiple slot format patterns, the terminal determines that the multiple slot format patterns are periodically repeated based on the slot format pattern configuration periodicity. Regarding the slot format pattern configuration periodicity, e.g., the TDD configuration periodicity contains multiple slot format patterns, the duration of the slot format pattern configuration periodicity is equal to the sum of the durations of the first periodicities corresponding to the multiple slot format patterns. Taking the configuration of 3 slot format patterns as an example, if the first periodicities of the 3 slot format patterns are equal to P, P1, P2 respectively, the duration of the TDD configuration periodicity is equal to P+P1+P2.

[0282] Exemplarily, the slot format pattern configuration period can be an integer multiple of N, i.e., N / slot format pattern configuration period is an integer, N is determined based on signaling indication or predefined manner. In the conventional mechanism, under the condition of configuring 2 slot format patterns, N=20 ms, exemplarily, if 3 slot format patterns are configured, N=30 ms or N=40 ms.

[0283] Exemplarily, the first time domain unit of each N / slot format pattern configuration period configuration period can be used as the starting position of the period, e.g., the first time domain unit corresponding to each F frames of OFDM symbols is used as the starting position of the period, wherein N=10 ms, then F=N / 10 ms.

[0284] (3) The time domain unit format configuration corresponding to the first slot format pattern in the first period is:

[0285] The configuration indicates the time domain unit format distribution in the first period, and the configuration contains information containing one or more of the following:

[0286] The first time domain unit number N1 in which the first slot format lasts;

[0287] The second time domain unit number N2 in which the first slot format lasts;

[0288] The first time domain unit number N3 in which the second slot format lasts;

[0289] The second time domain unit number N4 in which the second slot format lasts.

[0290] For example, as shown in FIG. 4A, in the case of the first period shown in the period, within the first period range, the terminal determines that the first N1 first time domain units within the first period range correspond to the first slot format;

[0291] After the first N1 first time domain units within the first period range, the terminal determines that the next N2 second time domain units correspond to the first slot format.

[0292] Within the first period range, the terminal determines that the last N3 first time domain units within the first period range correspond to the second slot format;

[0293] Before the last N3 first time domain units within the first period range, the terminal determines that the next N4 second time domain units correspond to the second slot format.

[0294] Wherein N1, N2, N3, N4 are integers greater than or equal to 0.

[0295] Example 1:

[0296] Taking a first time domain unit as a slot, a second time domain unit as a symbol, a first slot format corresponding to a flexible slot format F, and a second slot format corresponding to downlink D as an example, a third slot format corresponds to uplink U, a slot format pattern corresponds to a {FDU} time domain type order, and a time domain unit format pattern is repeatedly transmitted in the time domain type order of {FDU}.

[0297] Example 2:

[0298] Taking a first time domain unit as a slot, a second time domain unit as a symbol, a first slot format corresponding to U, and a second slot format corresponding to F as an example, a third slot format corresponds to D, a slot format pattern corresponds to a {UDF} time domain type order, and a time domain unit format pattern is repeatedly transmitted in the time domain type order of {UDF}.

[0299] Example 3:

[0300] Taking a first time domain unit as a slot, a second time domain unit as a symbol, a first slot format corresponding to F, and a second slot format corresponding to D as an example, a third slot format corresponds to U, a slot format pattern corresponds to a {FUD} time domain type order, and a time domain unit format pattern is repeatedly transmitted in the time domain type order of {FUD}.

[0308] Exemplarily, the first period contains N first sub-periods, N is greater than or equal to 1, and is determined based on signaling indication or pre-defined manner.

[0311] A first time domain unit number N1 at which the first slot format lasts;

[0312] A second time domain unit number N2 at which the first slot format lasts;

[0313] A first time domain unit number N3 at which the second slot format lasts;

[0314] A second time domain unit number N4 at which the second slot format lasts.

[0315] For example, as shown in FIG. 4A, in the case of a first sub-period of the period, within the range of the first sub-period, the terminal determines that the first N1 time domain units within the range of the first sub-period correspond to the first slot format;

[0316] After the first N1 time domain units within the range of the first sub-period, the terminal determines that the next N2 second time domain units correspond to the first slot format.

[0317] Within the range of the first sub-period, the terminal determines that the last N3 first time domain units within the range of the first sub-period correspond to the second slot format;

[0318] Before the last N3 first time domain units within the range of the first sub-period, the terminal determines that the next N4 second time domain units correspond to the second slot format.

[0319] Wherein, N1, N2, N3, N4 are integers greater than or equal to 0.

[0320] Example 1:

[0321] Taking the first time domain unit as a slot, the second time domain unit as a symbol, the first slot format corresponding to a flexible slot format F, and the second slot format corresponding to downlink D as an example, the third slot format corresponds to uplink U, the sub-slot format pattern corresponds to an {FDU} structure, and the corresponding time domain unit format pattern is repeatedly transmitted in the {FDU} structure.

[0322] Example 2:

[0323] Taking the first time domain unit as a slot, the second time domain unit as a symbol, the first slot format corresponding to U, and the second slot format corresponding to F as an example, the third slot format corresponds to D, the sub-slot format pattern corresponds to an {UDF} structure, and the corresponding time domain unit format pattern is repeatedly transmitted in the {UDF} structure.

[0324] Example 3:

[0325] Taking a first time domain unit as a slot, a second time domain unit as a symbol, a first slot format corresponding to F, and a second slot format corresponding to D as examples, a third slot format corresponds to U, a slot format pattern corresponds to a {FUD} structure, and a time domain unit format pattern is repeatedly transmitted in the {FUD} structure.

The specific slot format pattern configuration period is similar to Embodiment 1, which will not be described here.

[0340] (2) the time domain unit format corresponding to the first time domain unit is configured as:

[0345] Within the range of the first time domain unit, the terminal determines that the last N4 first sub-time domain units in the range of the first time domain unit correspond to the second slot format;

[0346] Wherein, N2, N4 are integers greater than or equal to 0.
