[0038] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.
[0039] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. The singular forms “a” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.
[0040] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to a determination."
[0041] For the sake of brevity and ease of understanding, this document uses the terms "greater than" or "less than", "higher than" or "lower than" to describe size relationships. However, it will be understood by those skilled in the art that the term "greater than" also includes the meaning of "greater than or equal to", and "less than" also includes the meaning of "less than or equal to"; the term "higher than" also includes the meaning of "higher than or equal to", and "lower than" also includes the meaning of "lower than or equal to".
[0042] In one embodiment, the network device can configure a sub-band for a first transmission direction for the terminal, wherein the first transmission direction includes, but is not limited to, uplink and downlink, that is, the network device can configure an uplink sub-band for the terminal, or it can configure a downlink sub-band for the terminal.
[0043] For example, when the first transmission direction is uplink, if the network device configures an uplink sub-band (i.e., configures a sub-band for the first transmission direction) in the downlink time domain unit configured for the terminal (denoted as the second transmission direction), then in this case, if the network device can perform full-duplex communication and the terminal can perform half-duplex communication, the terminal can perform uplink communication within the uplink sub-band or downlink communication on frequency domain resources outside the uplink sub-band in this downlink time domain unit. If both the network device and the terminal can perform full-duplex communication, the terminal can perform uplink communication within the uplink sub-band and downlink communication on frequency domain resources outside the uplink sub-band in this downlink time domain unit.
[0044] For example, when the first transmission direction is downlink, and the network device configures a downlink sub-band (i.e., a sub-band for the second transmission direction) in the time domain unit configured for the terminal (denoted as the second transmission direction) as uplink, the network device also configures a downlink sub-band in that uplink time domain unit. In this case, if the network device can perform full-duplex communication and the terminal can perform half-duplex communication, the terminal can perform downlink communication within the downlink sub-band in that uplink time domain unit, or perform uplink communication on frequency domain resources outside the downlink sub-band; if both the network device and the terminal can perform full-duplex communication, the terminal can perform downlink communication within the downlink sub-band and uplink communication on frequency domain resources outside the downlink sub-band in that uplink time domain unit.
[0045] However, some problems still exist when network devices configure subbands for terminals. For example, after a network device configures a subband for the first transmission direction for a terminal in a time domain unit, the terminal can only perform communication in the first transmission direction within that subband in that time domain unit, and cannot perform communication in the first transmission direction in other frequency domain resources.
[0046] Assuming the terminal is configured with an uplink subband, after the network device configures the uplink subband for the terminal in the downlink time domain unit, the terminal can only perform uplink communication within the uplink subband in the downlink time domain unit; uplink communication is not possible on frequency domain resources outside the uplink subband. However, even after the network device configures the uplink subband for the terminal in the uplink time domain unit, the terminal still can only perform downlink communication within the uplink subband in the uplink time domain unit, and uplink communication is not possible on frequency domain resources outside the uplink subband. This leads to a waste of frequency domain resources.
[0047] Taking a terminal configured with a downlink subband as an example, after the network device configures the downlink subband for the terminal in the uplink time domain unit, the terminal can only perform downlink communication within the downlink subband in the uplink time domain unit; downlink communication is not possible on frequency domain resources outside the downlink subband. However, even after the network device configures the downlink subband for the terminal in the downlink time domain unit, the terminal still can only perform downlink communication within the downlink subband in the downlink time domain unit, and downlink communication is not possible on frequency domain resources outside the downlink subband. This leads to a waste of frequency domain resources.
[0048] Figure 1 This is a schematic flowchart illustrating a resource determination method according to an embodiment of the present disclosure. The resource determination method shown in this embodiment can be executed by a terminal, which includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The terminal can communicate with network devices, which include, but are not limited to, network devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.
[0049] like Figure 1 As shown, the resource determination method may include the following steps:
[0050] In step S101, the time domain unit in which the sub-band of the first transmission direction is located is determined, and the second transmission direction of the time domain unit is determined;
[0051] In step S102, frequency domain resources available for communication in the first transmission direction on the time domain unit are determined based on the second transmission direction and the first transmission direction.
[0052] In one embodiment, the first transmission direction may include at least one of the following: the transmission direction of uplink (UL) time domain resources, which may be simply referred to as uplink; and the transmission direction of downlink (UL) time domain resources, which may be simply referred to as downlink.
[0053] In one embodiment, the second transmission direction may include at least one of the following: the transmission direction of uplink (UL) time domain resources, for example, simply referred to as uplink; the transmission direction of downlink (UL) time domain resources, for example, simply referred to as downlink; and the transmission direction of flexible time domain resources, for example, simply referred to as flexible.
[0054] In one embodiment, the time-domain unit includes at least one of the following: a slot and a symbol, wherein the symbol may be an orthogonal frequency division multiplexing (OFDM) symbol.
[0055] The time slot can be a time slot used for full-duplex communication, or a subband full-duplex (SBFD) time slot. If the network device can perform full-duplex communication and the terminal can perform half-duplex communication, in the time slot used for full-duplex communication, the network device can simultaneously receive and send data, and the terminal can simultaneously send or receive data. If both the network device and the terminal can perform full-duplex communication, in the time slot used for full-duplex communication, the network device can simultaneously receive and send data, and the terminal can simultaneously receive and send data.
[0056] Symbols can be symbols in time slots used for full-duplex communication. If the network device can perform full-duplex communication and the terminal can perform half-duplex communication, in the symbols used for full-duplex communication, the network device can simultaneously receive and send data, and the terminal can simultaneously send or receive data; if the network device can perform full-duplex communication and the terminal can perform full-duplex communication, in the symbols used for full-duplex communication, the network device can simultaneously receive and send data, and the terminal can simultaneously receive and send data.
[0057] According to this embodiment, after the terminal is configured with a sub-band for the first transmission direction by the network device, it can determine the time-domain unit where the sub-band for the first transmission direction is located, and determine the second transmission direction of the time-domain unit where the sub-band is located. Then, based on the second transmission direction and the first transmission direction, it can determine the frequency-domain resources available for communication in the first transmission direction within the time-domain unit. That is, the terminal can determine, based on the second transmission direction and the first transmission direction, whether to perform communication in the first transmission direction within the sub-band of that time-domain unit, or to perform communication in the first transmission direction across the entire frequency-domain resources corresponding to that time-domain unit. Therefore, this application is not limited to performing communication in the first transmission direction only within the sub-band of the first transmission direction. Accordingly, the frequency-domain resources corresponding to the time-domain unit where the sub-band for the first transmission direction is located can be fully utilized, which is beneficial for improving scheduling flexibility and communication efficiency.
[0058] Figure 2 This is a schematic flowchart illustrating another resource determination method according to an embodiment of the present disclosure. The step of determining the frequency domain resources available for communication in the first transmission direction on the time domain unit, based on the second transmission direction and the first transmission direction of the time domain unit, includes:
[0059] In step S201, when the first transmission direction is the same as the second transmission direction, it is determined that the frequency domain resources available for communication in the first transmission direction on the time domain unit include all frequency domain resources configured in the time domain unit; and / or
[0060] In step S202, when the first transmission direction is different from the second transmission direction, it is determined that the frequency domain resources available for communication in the first transmission direction on the time domain unit include the sub-band.
[0061] In one embodiment, when the first transmission direction and the second transmission direction are the same, the terminal can determine that the frequency domain resources available for communication in the first transmission direction on the time domain unit include all frequency domain resources configured in the time domain unit. That is, the terminal can perform communication in the first transmission direction on all frequency domain resources configured in the time domain unit, and is not limited to communication in the sub-band of the first transmission direction. Therefore, the frequency domain resources corresponding to the time domain unit where the sub-band of the first transmission direction is located are fully utilized, which is beneficial to improving scheduling flexibility and communication efficiency.
[0062] When the first transmission direction differs from the second transmission direction, the terminal determines that the frequency domain resources available for communication in the first transmission direction within the time domain unit include sub-bands. In one example, when the first transmission direction differs from the second transmission direction, the terminal determines that the frequency domain resources available for communication in the first transmission direction within the time domain unit are the sub-bands of the first transmission direction; that is, the terminal can only perform communication in the first transmission direction within the sub-bands of the first transmission direction. This situation satisfies the requirement that the terminal perform communication in the first transmission direction within the sub-bands of the first transmission direction.
[0063] In one embodiment, the first transmission direction is the same as the second transmission direction, including at least one of the following:
[0064] The first transmission direction is uplink, and the second transmission direction is uplink;
[0065] The first transmission direction is downlink, and the second transmission direction is downlink.
[0066] In one embodiment, the first transmission direction differs from the second transmission direction, including at least one of the following:
[0067] The first transmission direction is downlink, and the second transmission direction is uplink;
[0068] The first transmission direction is downlink, and the second transmission direction is flexible;
[0069] The first transmission direction is uplink, and the second transmission direction is downlink;
[0070] The first transmission direction is uplink, and the second transmission direction is flexible.
[0071] Specifically, when the second transmission direction of the time domain unit is uplink, uplink communication can be performed within the time domain unit; when the second transmission direction of the time domain unit is downlink, downlink communication can be performed within the time domain unit; when the transmission direction of the time domain unit is flexible, uplink communication can be performed within the time domain unit, and downlink communication can also be performed within the time domain unit.
[0072] Figure 3 This is a schematic flowchart illustrating yet another resource determination method according to embodiments of the present disclosure. Figure 3 As shown, determining the second transmission direction of the time-domain unit includes:
[0073] In step S301, the time-division duplex structure is determined based on the first semi-static signaling sent by the network device;
[0074] In step S302, the second transmission direction of the time domain unit is determined according to the time division duplex structure.
[0075] In one embodiment, the network device can configure a time-division duplex structure for the terminal via a first semi-static signaling. The time-division duplex structure is used to indicate the transmission direction of one or more time-domain units configured for the terminal, so that the terminal can determine the transmission direction of the time-domain units based on the time-division duplex structure.
[0076] In this context, when the transmission direction of a time domain unit is determined based on the first semi-static signaling, the time domain unit can be called a semi-static time domain unit. For example, when the transmission direction of a time slot is determined to be uplink based on the first semi-static signaling, the time slot can be called a semi-static uplink time slot (semi-static UL slot). When the transmission direction of a symbol is determined to be uplink based on the first semi-static signaling, the time slot can be called a semi-static uplink symbol (semi-static UL symbol).
[0077] In one embodiment, the first semi-static signaling includes at least one of the following:
[0078] Broadcast signaling;
[0079] Radio Resource Control (RRC) signaling.
[0080] In one embodiment, broadcast signaling includes, but is not limited to, System Information Block (SIB) and Other System Information (OSI), such as SIB1.
[0081] In one embodiment, radio resource control signaling may include UE-dedicated RRC signaling. Of course, in addition to using radio resource control signaling as the first semi-static signaling, other unicast signaling may also be used as the first semi-static signaling.
[0082] Taking the network device configuring the time division duplex structure for the terminal through UE-dedicated RRC signaling as an example, the UE-dedicated RRC signaling can carry the user equipment dedicated time division duplex uplink and downlink configuration (UE-dedicated TDD UL-DL configuration), which can characterize the time division duplex structure.
[0083] Figure 4 This is a schematic flowchart illustrating yet another resource determination method according to embodiments of the present disclosure. Figure 4 As shown, determining the second transmission direction of the time-domain unit further includes:
[0084] In step S401, the time division duplex structure is adjusted according to the dynamic indication information or the second semi-static signaling sent by the network device;
[0085] In step S402, the second transmission direction of the time domain unit is determined according to the adjusted time division duplex structure.
[0086] In one embodiment, the time-division duplex structure configured for the terminal by the network device via a first semi-static signaling is adjustable. For example, after configuring a first time-division duplex structure for the terminal via the first semi-static configuration, the network device can adjust the time-division duplex structure by sending a second semi-static signaling to the terminal, or by sending dynamic indication information to the terminal.
[0087] The second semi-static signaling can be, for example, broadcast signaling or RRC signaling. Its type can be the same as or different from the first semi-static signaling, and can be configured as needed. Dynamic indication information includes at least one information field from the Downlink Control Information (DCI), such as the SlotFrame Indicator (SFI) information field.
[0088] The terminal can adjust its configured time-division duplex structure based on dynamic indication information sent by the network device, or based on semi-static signaling sent by the network device. The terminal can then determine the second transmission direction of the time-domain unit based on the adjusted time-division duplex structure.
[0089] It should be noted that adjusting the time-division duplex structure can change the transmission direction of the time-domain unit. For example, it can change the transmission direction of the flexible time-domain unit, while the transmission direction of the uplink and downlink time-domain units can remain unchanged.
[0090] Figure 5A This is a schematic diagram of a time slot according to an embodiment of the present disclosure. Figure 5B This is a schematic diagram of another time slot shown according to an embodiment of the present disclosure. Figure 5C This is a schematic diagram of a sub-band according to an embodiment of the present disclosure.
[0091] In one example, such as Figure 5AAs shown, the network device sends UE-dedicated RRC signaling to the terminal, which carries the UE-dedicated TDD UL-DL configuration. Taking a cycle consisting of 5 time slots as an example, the terminal determines the TDD structure as DDFFF based on the UE-dedicated TDD UL-DL configuration. Here, "D" represents the DL slot, and "F" represents the flexible slot. That is, in one cycle, slots #0 to #1 are DL slots, and slots #2 to #4 are flexible slots.
[0092] like Figure 5B As shown, the network device sends DCI format 2_0 to the terminal. The SFI in DCI format 2_0 indicates that the new TDD structure is DDDFU. The terminal can determine that the TDD structure has been adjusted from DDDFU to DDDFU based on the SFI in DCI format 2_0. Here, "U" is used to represent the UL slot.
[0093] Alternatively, the network device may resend the UE-dedicated RRC signaling to the terminal. The UE-dedicated TDD UL-DL configuration carried in the resent UE-dedicated RRC signaling configures the TDD structure as DDDFU. The terminal can determine that the TDD structure is DDDFU based on the UE-dedicated RRC signaling resent by the network device, and thus determine that the TDD structure has been adjusted from DDDFU to DDDFU.
[0094] Compared to the original TDD structure DDDFU, the adjusted TDD structure DDDFU determines that slots #0, #1, and #3 remain unchanged, the transmission direction of slot #2 is changed from flexible to DL, and the transmission direction of slot #4 is changed from flexible to UL.
[0095] like Figure 5CAs shown, the network device configures an uplink subband (UL subband) for the terminal, meaning the first transmission direction is UL. The terminal can determine that the uplink subband is located in slots #1 to #4, and can also determine the transmission direction (i.e., the second transmission direction) of each time domain unit where the uplink subband is located. Specifically, the transmission direction of slots #1 to #2 is DL, the transmission direction of slot #3 is flexible, and the transmission direction of slot #4 is UL.
[0096] If the terminal can determine that the first transmission direction UL and the second transmission direction UL are the same in slot #4, then the frequency domain resources available for uplink communication in slot #4 include all the frequency domain resources configured for slot #4. Thus, the terminal can transmit uplink data to the network device in the uplink subband in slot #4, or it can transmit uplink data to the network device in the frequency domain resources outside the uplink subband configured for slot #4.
[0097] In slots #1 and #2, the first transmission direction UL and the second transmission direction DL are different. In slot #3, the first transmission direction UL and the second transmission direction flexible are different. Therefore, the frequency domain resources available for uplink communication in slots #1 and #3 are the uplink subband. That is, the terminal can only transmit uplink data to the network device in the uplink subband in slots #1 and #3, and cannot use frequency domain resources outside the uplink subband to transmit uplink data to the network device.
[0098] Therefore, when the second transmission direction of the time domain unit containing the sub-band of the first transmission direction is the same as the first transmission direction, the terminal can use all the frequency domain resources configured in the time domain unit for communication in the first transmission direction. For example, in Figure 5C In the illustrated embodiment, when performing uplink communication on slot #4, all frequency domain resources configured for slot #4 can be used for uplink communication, rather than being limited to using the frequency domain resources corresponding to the uplink sub-band. Therefore, the frequency domain resources corresponding to slot #4 can be fully utilized, which is beneficial for improving scheduling flexibility and communication efficiency.
[0099] The above embodiments mainly illustrate the technical solution of this disclosure when the first transmission direction is uplink. The following embodiments illustrate the technical solution of this disclosure when the first transmission direction is downlink.
[0100] Figure 6A This is a schematic diagram of a time slot according to an embodiment of the present disclosure. Figure 6B This is a schematic diagram of another time slot shown according to an embodiment of the present disclosure. Figure 6CThis is a schematic diagram of a sub-band according to an embodiment of the present disclosure.
[0101] like Figure 6A As shown, the network device sends the UE-dedicated TDDUL-DL configuration to the terminal through UE-dedicated RRC signaling. Taking a period of 5 time slots as an example, the terminal determines the TDD structure as DFFUU according to the UE-dedicated TDD UL-DL configuration, that is, slot #0 is the DL slot, slots #1 to #2 are flexible slots, and slots #3 to #4 are UL slots.
[0102] like Figure 6B As shown, the network device sends DCI format 2_0 to the terminal. The SFI in DCI format 2_0 indicates that the new TDD structure is DDFUU. The terminal can determine that the TDD structure has been changed from DFFUU to DDFUU based on the SFI in DCI format 2_0.
[0103] Alternatively, the network device may resend the UE-dedicated RRC signaling to the terminal. The UE-dedicated TDD UL-DL configuration carried in the resent UE-dedicated RRC signaling configures the TDD structure as DDFUU. The terminal can determine that the TDD structure is DDFUU based on the UE-dedicated RRC signaling resent by the network device, and thus determine that the TDD structure has been adjusted from DFFUU to DDFUU.
[0104] Compared to the original TDD structure DFFUU, the adjusted TDD structure DDFUU determines that slots #0, #2 to #4 remain unchanged, while the transmission direction of slot #1 is changed from flexible to DL.
[0105] like Figure 6C As shown, the network device configures a downlink subband (DL subband) for the terminal, meaning the first transmission direction is DL. The terminal can determine that the downlink subband is located in slots #1 to #3, and can also determine the transmission direction (i.e., the second transmission direction) of each time domain unit where the downlink subband is located. Specifically, the transmission direction of slot #1 is DL, the transmission direction of slot #2 is flexible, and the transmission direction of slot #3 is UL.
[0106] If the terminal can determine that the first transmission direction DL and the second transmission direction DL are the same in slot#1, then the frequency domain resources available for downlink communication in slot#1 include all the frequency domain resources configured in slot#1. Thus, the terminal can receive downlink data transmitted by the network device in the downlink subband in slot#1, or it can receive downlink data transmitted by the network device in the frequency domain resources outside the downlink subband configured in slot#1.
[0107] In slot #2, the first transmission direction DL is different from the second transmission direction flexible. In slot #3, the first transmission direction DL is different from the second transmission direction UL. Therefore, the frequency domain resources available for downlink communication in slots #2 and #3 are downlink subbands. That is, the terminal can only receive downlink data transmitted by the network device in the downlink subband in slots #2 and #3, and cannot use frequency domain resources outside the downlink subband to receive downlink data transmitted by the network device.
[0108] Therefore, when the second transmission direction of the time domain unit containing the sub-band of the first transmission direction is the same as the first transmission direction, all frequency domain resources configured in the time domain unit can be used for communication in the first transmission direction. For example, in Figure 6C In the illustrated embodiment, when performing downlink communication on slot #1, all frequency domain resources configured for slot #1 can be used for downlink communication, rather than being limited to using the frequency domain resources corresponding to the downlink sub-band. Therefore, the frequency domain resources corresponding to slot #1 can be fully utilized, which is beneficial for improving scheduling flexibility and communication efficiency.
[0109] The technical solutions of this disclosure will be illustrated by several further embodiments below.
[0110] Figure 7A This is a schematic diagram of a time slot according to an embodiment of the present disclosure. Figure 7B This is a schematic diagram of a sub-band according to an embodiment of the present disclosure.
[0111] like Figure 7A As shown, the network device is configured with a dual-cycle time division duplex (TDD) structure for the terminal, with each cycle consisting of 5 time slots.
[0112] The first cycle has five time slots, slots #0 to #4, and the second cycle has five time slots, slots #5 to #9. The TDD structure for the first cycle is DDDFU, meaning slots #0 to #2 are DL slots, slot #3 is a flexible slot, and slot #4 is a UL slot. The TDD structure for the second cycle is DDFUU, meaning slots #5 to #6 are DL slots, slot #7 is a flexible slot, and slots #8 to #9 are UL slots.
[0113] like Figure 7B As shown, the network device configures an uplink subband (UL subband) for the terminal, meaning the first transmission direction is uplink. The terminal can determine that the uplink subband is located in slots #0 to #6, and can also determine the transmission direction (i.e., the second transmission direction) of each time domain unit where the uplink subband is located. Specifically, the transmission directions of slots #0 to #2 and slots #5 to #6 are DL, the transmission direction of slot #3 is flexible, and the transmission direction of slot #4 is UL.
[0114] If the terminal can determine that the first transmission direction UL and the second transmission direction UL are the same in slot #4, then the frequency domain resources available for uplink communication in slot #4 include all the frequency domain resources configured for slot #4. Thus, the terminal can transmit uplink data to the network device in the uplink subband in slot #4, or it can transmit uplink data to the network device in the frequency domain resources outside the uplink subband configured for slot #4.
[0115] In slots #0 to #2 and slots #5 to #6, the first transmission direction UL and the second transmission direction DL are different. In slot #3, the first transmission direction UL and the second transmission direction flexible are different. Therefore, the frequency domain resources available for uplink communication in slots #0 to #3 and slots #5 to #6 are uplink subbands. That is, the terminal can only transmit uplink data to the network device in the uplink subband in slots #0 to #3 and slots #5 to #6, and cannot use frequency domain resources outside the uplink subband to transmit uplink data to the network device.
[0116] Therefore, when the second transmission direction of the time domain unit containing the sub-band of the first transmission direction is the same as the first transmission direction, all frequency domain resources configured in the time domain unit can be used for communication in the first transmission direction. For example, in Figure 7BIn the illustrated embodiment, when performing uplink communication on slot #4, all frequency domain resources configured for slot #4 can be used for uplink communication, rather than being limited to using the frequency domain resources corresponding to the uplink sub-band. Therefore, the frequency domain resources corresponding to slot #4 can be fully utilized, which is beneficial for improving scheduling flexibility and communication efficiency.
[0117] The above embodiments mainly illustrate the technical solution of this disclosure when the time domain unit is a time slot. The following embodiments illustrate the technical solution of this disclosure when the time domain unit is a symbol.
[0118] Figure 8A This is a schematic diagram of a symbol according to an embodiment of the present disclosure. Figure 8B This is a schematic diagram of a sub-band according to an embodiment of the present disclosure.
[0119] like Figure 8A As shown, a time slot can include 14 symbols. For example, the symbol structure in the time slot configured by the network device for the terminal is DDDDDDDDDFUUUU, that is, the 1st to 9th symbols are DL symbols, the 10th symbol is flexible symbol, and the 11th to 14th symbols are UL symbols.
[0120] like Figure 8B As shown, the network device configures an uplink subband (UL subband) for the terminal, meaning the first transmission direction is uplink. The terminal can determine that the uplink subband is located in symbols 9 to 11, and can also determine the transmission direction (i.e., the second transmission direction) of each time domain unit where the uplink subband is located. Specifically, the transmission direction of symbol 9 is DL, the transmission direction of symbol 10 is flexible, and the transmission direction of symbol 11 is UL.
[0121] If the terminal can determine that the first transmission direction UL and the second transmission direction UL are the same on the 11th symbol, then the frequency domain resources available for uplink communication on the 11th symbol include all the frequency domain resources configured on the 11th symbol. Thus, the terminal can transmit uplink data to the network device in the uplink subband on the 11th symbol, or it can transmit uplink data to the network device in the frequency domain resources outside the uplink subband configured in slot#4.
[0122] In the 9th symbol, the first transmission direction UL is different from the second transmission direction DL. In the 10th symbol, the first transmission direction UL is different from the second transmission direction flexible. Therefore, the frequency domain resources available for uplink communication in the 10th and 11th symbols are the uplink subband. That is, the terminal can only transmit uplink data to the network device in the uplink subband in the 10th and 11th symbols, and cannot use frequency domain resources outside the uplink subband to transmit uplink data to the network device.
[0123] Therefore, when the second transmission direction of the time domain unit containing the sub-band of the first transmission direction is the same as the first transmission direction, all frequency domain resources configured in the time domain unit can be used for communication in the first transmission direction. For example, in Figure 8B In the illustrated embodiment, when uplink communication is performed on the 11th symbol, all frequency domain resources configured for the 11th symbol can be used for uplink communication, rather than being limited to using the frequency domain resources corresponding to the uplink subband. Therefore, the frequency domain resources corresponding to the 11th symbol can be fully utilized, which is beneficial for improving scheduling flexibility and communication efficiency.
[0124] Figure 9 This is a schematic flowchart illustrating a resource determination method according to an embodiment of the present disclosure. The resource determination method shown in this embodiment can be executed by a network device that can communicate with a terminal. The network device includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices.
[0125] like Figure 9 As shown, the resource determination method may include the following steps:
[0126] In step S901, the time domain unit in which the sub-band of the first transmission direction configured for the terminal is located is determined, and the second transmission direction of the time domain unit is determined;
[0127] In step S902, frequency domain resources available for communication with the terminal in the time domain unit in the first transmission direction are determined based on the second transmission direction and the first transmission direction.
[0128] In one embodiment, the first transmission direction may include at least one of the following: the transmission direction of uplink (UL) time domain resources, which may be simply referred to as uplink; and the transmission direction of downlink (UL) time domain resources, which may be simply referred to as downlink.
[0129] In one embodiment, the second transmission direction may include at least one of the following: the transmission direction of uplink (UL) time domain resources, for example, simply referred to as uplink; the transmission direction of downlink (UL) time domain resources, for example, simply referred to as downlink; and the transmission direction of flexible time domain resources, for example, simply referred to as flexible.
[0130] In one embodiment, the time-domain unit includes at least one of the following: a slot and a symbol, wherein the symbol may be an OFDM symbol.
[0131] The time slot can be a time slot used for full-duplex communication, also known as SBFD time. If the network device can perform full-duplex communication and the terminal can perform half-duplex communication, in the time slot used for full-duplex communication, the network device can simultaneously receive and send data, and the terminal can simultaneously send or receive data. If both the network device and the terminal can perform full-duplex communication, in the time slot used for full-duplex communication, the network device can simultaneously receive and send data, and the terminal can simultaneously receive and send data.
[0132] Symbols can be symbols in time slots used for full-duplex communication. If the network device can perform full-duplex communication and the terminal can perform half-duplex communication, in the symbols used for full-duplex communication, the network device can simultaneously receive and send data, and the terminal can simultaneously send or receive data; if the network device can perform full-duplex communication and the terminal can perform full-duplex communication, in the symbols used for full-duplex communication, the network device can simultaneously receive and send data, and the terminal can simultaneously receive and send data.
[0133] According to this embodiment, after the network device configures a sub-band for the terminal in the first transmission direction, it can determine the time domain unit where the sub-band in the first transmission direction is located, and determine the second transmission direction of the time domain unit where the sub-band is located. Then, based on the second transmission direction and the first transmission direction, it can determine the frequency domain resources available for communication in the first transmission direction within the time domain unit. That is, the terminal can determine, based on the second transmission direction and the first transmission direction, whether to conduct communication in the first transmission direction within the sub-band of that time domain unit, or to conduct communication in the first transmission direction across the entire frequency domain resources corresponding to that time domain unit. Therefore, this application is not limited to communicating with the terminal only within the sub-band of the first transmission direction. Accordingly, the frequency domain resources corresponding to the time domain unit where the sub-band in the first transmission direction is located can be fully utilized, which is beneficial for improving scheduling flexibility and communication efficiency.
[0134] Figure 10 This is a schematic flowchart illustrating another resource determination method according to embodiments of the present disclosure. Figure 10As shown, determining the frequency domain resources available for communication with the terminal in the time domain unit in the first transmission direction, based on the second transmission direction and the first transmission direction of the time domain unit, includes:
[0135] In step S1001, when the first transmission direction is the same as the second transmission direction, it is determined that the frequency domain resources available for communication with the terminal in the time domain unit in the first transmission direction include all frequency domain resources configured in the time domain unit; and / or
[0136] In step S1002, when the first transmission direction is different from the second transmission direction, it is determined that the frequency domain resources available for communication with the terminal in the time domain unit in the first transmission direction include the sub-band.
[0137] In one embodiment, when the first transmission direction and the second transmission direction are the same, the network device can determine that the frequency domain resources available for communication with the terminal in the first transmission direction on the time domain unit include all frequency domain resources configured in the time domain unit. That is, the network device can schedule the terminal to communicate in the first transmission direction on all frequency domain resources configured in the time domain unit, thereby enabling communication with the terminal in the first transmission direction on all frequency domain resources configured in the time domain unit, rather than being limited to communication with the terminal in the first transmission direction sub-band. Accordingly, the frequency domain resources corresponding to the time domain unit where the sub-band of the first transmission direction is located are fully utilized, which is beneficial to improving scheduling flexibility and communication efficiency.
[0138] When the first transmission direction differs from the second transmission direction, the network device determines that the frequency domain resources available for communication in the first transmission direction within the time domain unit include sub-bands of the first transmission direction. In one example, when the first transmission direction differs from the second transmission direction, the terminal determines that the frequency domain resources available for communication in the first transmission direction within the time domain unit are the sub-bands of the first transmission direction. That is, the network device can only communicate with the terminal in the first transmission direction within the sub-bands of the first transmission direction. This situation satisfies the terminal's requirement to communicate in the first transmission direction within its sub-bands.
[0139] In one embodiment, the time-domain unit includes at least one of the following:
[0140] Time slots used for full-duplex communication;
[0141] Symbols in a time slot used for full-duplex communication.
[0142] In one embodiment, the first transmission direction is different from the second transmission direction, including at least one of the following:
[0143] The first transmission direction is downlink, and the second transmission direction is uplink;
[0144] The first transmission direction is downlink, and the second transmission direction is flexible;
[0145] The first transmission direction is uplink, and the second transmission direction is downlink;
[0146] The first transmission direction is uplink, and the second transmission direction is flexible.
[0147] Specifically, when the second transmission direction of the time domain unit is uplink, uplink communication can be performed by the terminal within the time domain unit; when the second transmission direction of the time domain unit is downlink, downlink communication can be performed by the terminal within the time domain unit; when the transmission direction of the time domain unit is flexible, uplink communication can be performed by the terminal within the time domain unit, or downlink communication can be performed by the terminal within the time domain unit.
[0148] Figure 11 This is a schematic flowchart illustrating yet another resource determination method according to embodiments of the present disclosure. Figure 11 As shown, the method further includes:
[0149] In step S1101, a first semi-static signaling is sent to the terminal, wherein the first semi-static signaling is used to configure a time-division duplex structure, and the time-division duplex structure is used to indicate the second transmission direction of the time-domain unit.
[0150] In one embodiment, the network device can configure a time-division duplex structure for the terminal via a first semi-static signaling. The time-division duplex structure is used to indicate the transmission direction of one or more time-domain units configured for the terminal, so that the terminal can determine the transmission direction of the time-domain units based on the time-division duplex structure.
[0151] In this context, when the transmission direction of a time domain unit is determined based on the first semi-static signaling, the time domain unit can be called a semi-static time domain unit. For example, when the transmission direction of a time slot is determined to be uplink based on the first semi-static signaling, the time slot can be called a semi-static uplink time slot (semi-static UL slot). When the transmission direction of a symbol is determined to be uplink based on the first semi-static signaling, the time slot can be called a semi-static uplink symbol (semi-static UL symbol).
[0152] In one embodiment, the first semi-static signaling includes at least one of the following:
[0153] Broadcast signaling;
[0154] Radio Resource Control (RRC) signaling.
[0155] In one embodiment, broadcast signaling includes, but is not limited to, SIB and OSI; for example, SIB may include SIB1.
[0156] In one embodiment, RRC signaling may include UE-dedicated RRC signaling. Of course, in addition to using RRC signaling as the first semi-static signaling, other unicast signaling may also be used as the first semi-static signaling.
[0157] Taking the network device configuring the time division duplex structure for the terminal through UE-dedicated RRC signaling as an example, the UE-dedicated RRC signaling can carry the UE-dedicated TDD UL-DL configuration, which can characterize the time division duplex structure.
[0158] Figure 12 This is a schematic flowchart illustrating yet another resource determination method according to embodiments of the present disclosure. Figure 12 As shown, the method further includes:
[0159] In step S1201, dynamic indication information or second semi-static signaling is sent to the terminal, wherein the dynamic indication information or second semi-static signaling is used to adjust the time division duplex structure;
[0160] In step S1202, the second transmission direction of the time domain unit is determined according to the adjusted time division duplex structure.
[0161] In one embodiment, the time-division duplex structure configured for the terminal by the network device via a first semi-static signaling is adjustable. For example, after configuring a first time-division duplex structure for the terminal via the first semi-static configuration, the network device can adjust the time-division duplex structure by sending a second semi-static signaling to the terminal, or by sending dynamic indication information to the terminal.
[0162] The second semi-static signaling can be, for example, broadcast signaling or RRC signaling. Its type can be the same as or different from the first semi-static signaling, and can be configured as needed. Dynamic indication information includes at least one information field in the DCI, such as the SFI information field.
[0163] The terminal can adjust its configured time-division duplex structure based on dynamic indication information sent by the network device, or based on semi-static signaling sent by the network device. The terminal can then determine the second transmission direction of the time-domain unit based on the adjusted time-division duplex structure.
[0164] It should be noted that adjusting the time-division duplex structure can change the transmission direction of the time-domain unit. For example, it can change the transmission direction of the flexible time-domain unit, while the transmission direction of the uplink and downlink time-domain units can remain unchanged.
[0165] In one example, such as Figure 5A As shown, the network device sends UE-dedicated RRC signaling to the terminal, which carries the UE-dedicated TDD UL-DL configuration. Taking a cycle consisting of 5 time slots as an example, the network device determines the TDD structure as DDFFF based on the UE-dedicated TDD UL-DL configuration sent to the terminal. Here, "D" represents the DL slot, and "F" represents the flexible slot. That is, in one cycle, slots #0 to #1 are DL slots, and slots #2 to #4 are flexible slots.
[0166] like Figure 5B As shown, the network device sends DCI format 2_0 to the terminal. The SFI in DCI format 2_0 indicates that the new TDD structure is DDDFU. The network device can determine that the TDD structure has been changed from DDDFU to DDDFU based on the SFI in DCI format 2_0 sent to the terminal. Here, "U" is used to represent UL slot.
[0167] Alternatively, the network device can resend the UE-dedicated RRC signaling to the terminal. By using the UE-dedicated TDD UL-DL configuration carried in the resent UE-dedicated RRC signaling, the TDD structure can be configured as DDDFU. Based on the resent UE-dedicated RRC signaling, the network device can determine that the TDD structure is DDDFU, and thus determine that the TDD structure has been adjusted from DDDFU to DDDFU.
[0168] Compared to the original TDD structure DDDFU, the adjusted TDD structure DDDFU determines that slots #0, #1, and #3 remain unchanged, the transmission direction of slot #2 is changed from flexible to DL, and the transmission direction of slot #4 is changed from flexible to UL.
[0169] like Figure 5C As shown, the network device configures the terminal with a UL subband, meaning the first transmission direction is UL. The terminal can determine that the uplink subband is located in slots #1 to #4, and can also determine the transmission direction (i.e., the second transmission direction) of each time domain unit where the uplink subband is located. Specifically, the transmission direction of slots #1 to #2 is DL, the transmission direction of slot #3 is flexible, and the transmission direction of slot #4 is UL.
[0170] If the network device can determine that the first transmission direction UL and the second transmission direction UL are the same in slot #4, then the frequency domain resources that the terminal can use for uplink communication in slot #4 include all the frequency domain resources configured in slot #4. Thus, the network device can receive uplink data sent by the terminal in the uplink subband in slot #4, or it can receive uplink data sent by the terminal in the frequency domain resources outside the uplink subband configured in slot #4.
[0171] In slots #1 and #2, the first transmission direction UL and the second transmission direction DL are different. In slot #3, the first transmission direction UL and the second transmission direction flexible are different. Therefore, the frequency domain resources available for uplink communication in slots #1 and #3 are the uplink subband. In other words, network devices in slots #1 and #3 can only receive uplink data sent by the terminal in the uplink subband, and cannot use frequency domain resources outside the uplink subband to receive uplink data sent by the terminal.
[0172] Therefore, when the second transmission direction of the time domain unit containing the sub-band of the first transmission direction is the same as the first transmission direction, the network device can use all the frequency domain resources configured in the time domain unit to communicate with the terminal in the first transmission direction. For example, in Figure 5C In the illustrated embodiment, when performing uplink communication on slot #4, all frequency domain resources configured for slot #4 can be used to communicate with the terminal. That is, the network device can schedule the terminal for uplink transmission on all frequency domain resources configured for slot #4, rather than being limited to using the frequency domain resources corresponding to the uplink sub-band. Therefore, the frequency domain resources corresponding to slot #4 can be fully utilized, which is beneficial for improving scheduling flexibility and communication efficiency.
[0173] The above embodiments mainly illustrate the technical solution of this disclosure when the first transmission direction is uplink. The following embodiments illustrate the technical solution of this disclosure when the first transmission direction is downlink.
[0174] like Figure 6AAs shown, the network device sends the UE-dedicated TDDUL-DL configuration to the terminal through UE-dedicated RRC signaling. Taking a period of 5 time slots as an example, the network device determines the TDD structure as DFFUU according to the UE-dedicated TDD UL-DL configuration, that is, slot #0 is the DL slot, slots #1 to #2 are flexible slots, and slots #3 to #4 are UL slots.
[0175] like Figure 6B As shown, the network device sends DCI format 2_0 to the terminal. The SFI in DCI format 2_0 indicates that the new TDD structure is DDFUU. The network device can determine that the TDD structure has been changed from DFFUU to DDFUU based on the SFI in DCI format 2_0.
[0176] Alternatively, the network device can resend the UE-dedicated RRC signaling to the terminal. By using the UE-dedicated TDD UL-DL configuration carried in the resent UE-dedicated RRC signaling, the TDD structure can be configured as DDFUU. Based on the resent UE-dedicated RRC signaling, the network device can determine that the TDD structure is DDFUU, and thus determine that the TDD structure has been adjusted from DFFUU to DDFUU.
[0177] Compared to the original TDD structure DFFUU, the adjusted TDD structure DDFUU determines that slots #0, #2 to #4 remain unchanged, while the transmission direction of slot #1 is changed from flexible to DL.
[0178] like Figure 6C As shown, the network device configures a downlink subband (DL subband) for the terminal, meaning the first transmission direction is DL. The network device can determine that the downlink subband is located in slots #1 to #3, and can also determine the transmission direction (i.e., the second transmission direction) of each time domain unit where the downlink subband is located. Specifically, the transmission direction of slot #1 is DL, the transmission direction of slot #2 is flexible, and the transmission direction of slot #3 is UL.
[0179] If the network device can determine that the first transmission direction DL and the second transmission direction DL are the same in slot#1, then the frequency domain resources available for downlink communication in slot#1 include all the frequency domain resources configured in slot#1. Thus, the network device can send downlink data to the terminal in the downlink subband in slot#1, or it can send downlink data to the terminal in the frequency domain resources outside the downlink subband configured in slot#1.
[0180] In slot #2, the first transmission direction DL is different from the second transmission direction flexible. In slot #3, the first transmission direction DL is different from the second transmission direction UL. Therefore, the frequency domain resources available for downlink communication in slots #2 and #3 are downlink subbands. In other words, network devices in slots #2 and #3 can only send downlink data to the terminal in the downlink subband, and cannot use frequency domain resources outside the downlink subband to send downlink data to the terminal.
[0181] Therefore, when the second transmission direction of the time domain unit containing the sub-band of the first transmission direction is the same as the first transmission direction, all frequency domain resources configured in the time domain unit can be used for communication in the first transmission direction. For example, in Figure 6C In the illustrated embodiment, when performing downlink communication on slot #1, the network device can use all the frequency domain resources configured for slot #1 to communicate with the terminal. That is, the network device can schedule the terminal to receive downlink signals on all the frequency domain resources configured for slot #1, rather than being limited to using the frequency domain resources corresponding to the downlink subband. Therefore, the frequency domain resources corresponding to slot #1 can be fully utilized, which is beneficial for improving scheduling flexibility and communication efficiency.
[0182] The technical solutions of this disclosure will be illustrated by several further embodiments below.
[0183] Figure 7A This is a schematic diagram of a time slot according to an embodiment of the present disclosure. Figure 7B This is a schematic diagram of a sub-band according to an embodiment of the present disclosure.
[0184] like Figure 7A As shown, the network device is configured with a dual-cycle time division duplex (TDD) structure for the terminal, with each cycle consisting of 5 time slots.
[0185] The first cycle has five time slots, slots #0 to #4, and the second cycle has five time slots, slots #5 to #9. The TDD structure for the first cycle is DDDFU, meaning slots #0 to #2 are DL slots, slot #3 is a flexible slot, and slot #4 is a UL slot. The TDD structure for the second cycle is DDFUU, meaning slots #5 to #6 are DL slots, slot #7 is a flexible slot, and slots #8 to #9 are UL slots.
[0186] like Figure 7B As shown, the network device configures an uplink subband (UL subband) for the terminal, meaning the first transmission direction is uplink. The network device can determine that the uplink subband is located in slots #0 to #6, and can also determine the transmission direction (i.e., the second transmission direction) of each time domain unit where the uplink subband is located. Specifically, the transmission directions of slots #0 to #2 and slots #5 to #6 are DL, the transmission direction of slot #3 is flexible, and the transmission direction of slot #4 is UL.
[0187] If the network device can determine that the first transmission direction UL and the second transmission direction UL are the same in slot #4, then the frequency domain resources available for uplink communication in slot #4 include all the frequency domain resources configured for slot #4. Thus, the terminal can receive uplink data sent by the terminal in the uplink subband in slot #4, or it can receive uplink data sent by the terminal in the frequency domain resources outside the uplink subband configured for slot #4.
[0188] In slots #0 to #2 and slots #5 to #6, the first transmission direction UL and the second transmission direction DL are different. In slot #3, the first transmission direction UL and the second transmission direction flexible are different. Therefore, the frequency domain resources available for uplink communication in slots #0 to #3 and slots #5 to #6 are uplink subbands. In other words, network devices in slots #0 to #3 and slots #5 to #6 can only receive uplink data sent by the terminal in the uplink subband, and cannot use frequency domain resources outside the uplink subband to receive uplink data sent by the terminal.
[0189] Therefore, when the second transmission direction of the time domain unit containing the sub-band of the first transmission direction is the same as the first transmission direction, the network device can use all the frequency domain resources configured in the time domain unit for communication in the first transmission direction. For example, in Figure 7BIn the illustrated embodiment, when performing uplink communication on slot #4, all frequency domain resources configured for slot #4 can be used to communicate with the terminal. That is, the network device can schedule the terminal for uplink transmission on all frequency domain resources configured for slot #4, rather than being limited to using the frequency domain resources corresponding to the uplink sub-band. Therefore, the frequency domain resources corresponding to slot #4 can be fully utilized, which is beneficial for improving scheduling flexibility and communication efficiency.
[0190] The above embodiments mainly illustrate the technical solution of this disclosure when the time domain unit is a time slot. The following embodiments illustrate the technical solution of this disclosure when the time domain unit is a symbol.
[0191] like Figure 8A As shown, a time slot can include 14 symbols. For example, the symbol structure in the time slot configured by the network device for the terminal is DDDDDDDDDFUUUU, that is, the 1st to 9th symbols are DL symbols, the 10th symbol is flexible symbol, and the 11th to 14th symbols are UL symbols.
[0192] like Figure 8B As shown, the network device configures an uplink subband (UL subband) for the terminal, meaning the first transmission direction is uplink. The network device can determine that the uplink subband is located in symbols 9 to 11, and can also determine the transmission direction (i.e., the second transmission direction) of each time domain unit where the uplink subband is located. Specifically, the transmission direction of symbol 9 is DL, the transmission direction of symbol 10 is flexible, and the transmission direction of symbol 11 is UL.
[0193] If the network device can determine that the first transmission direction UL and the second transmission direction UL are the same on the 11th symbol, then the frequency domain resources available for uplink communication on the 11th symbol include all the frequency domain resources configured on the 11th symbol. Thus, the network device can receive uplink data sent by the terminal in the uplink subband on the 11th symbol, or it can receive uplink data sent by the terminal in the frequency domain resources outside the uplink subband configured in slot#4.
[0194] In the 9th symbol, the first transmission direction UL is different from the second transmission direction DL. In the 10th symbol, the first transmission direction UL is different from the second transmission direction flexible. Therefore, the frequency domain resources available for uplink communication in the 10th and 11th symbols are the uplink subband. That is, the network device can only receive uplink data sent by the terminal in the uplink subband in the 10th and 11th symbols, and cannot use frequency domain resources outside the uplink subband to receive uplink data sent by the terminal.
[0195] Therefore, when the second transmission direction of the time domain unit containing the sub-band of the first transmission direction is the same as the first transmission direction, the network device can use all the frequency domain resources configured in the time domain unit to communicate with the terminal in the first transmission direction. For example, in Figure 8B In the illustrated embodiment, when uplink communication occurs on the 11th symbol, the network device can use all the frequency domain resources configured for the 11th symbol to communicate uplink with the terminal. That is, the network device can schedule the terminal for uplink transmission on all the frequency domain resources configured for the 11th symbol, rather than being limited to using the frequency domain resources corresponding to the uplink subband. Therefore, the frequency domain resources corresponding to the 11th symbol can be fully utilized, which is beneficial for improving scheduling flexibility and communication efficiency.
[0196] Figure 8C This is a schematic diagram illustrating the interaction between a terminal and a network device, as shown in an embodiment of this disclosure.
[0197] like Figure 8C As shown, the network device can send configuration information for the time domain unit and configuration information for the transmission subband to the terminal. Correspondingly, the terminal receives the configuration information for the time domain unit and the configuration information for the transmission subband sent by the network device.
[0198] The terminal determines the first transmission direction of the sub-band and the second transmission direction of the time domain unit where the sub-band is located based on the configuration information of the time domain unit and the sub-band configuration information sent by the network device.
[0199] The terminal determines the frequency domain resources available for communication in the first transmission direction in the time domain unit based on the first transmission direction of the sub-band and the second transmission direction of the time domain unit where the sub-band is located.
[0200] In one example, when the first transmission direction of the subband and the second transmission direction of the time domain unit where the subband is located are the same, the terminal can determine that the frequency domain resources available for communication in the first transmission direction on the time domain unit include all the frequency domain resources configured in the time domain unit.
[0201] For example, if the first transmission direction is uplink and the second transmission direction is uplink, the terminal can determine that the first and second transmission directions are the same, and therefore can determine that the available resources for uplink transmission in the time domain unit include all frequency domain resources configured in the time domain unit. Correspondingly, within the time domain unit, the network device can schedule the terminal to perform uplink transmission on all frequency domain resources configured in the time domain unit.
[0202] For example, if the first transmission direction is downlink and the second transmission direction is downlink, the terminal can determine that the first and second transmission directions are the same, and therefore can determine that the downlink transmission can be performed in the time domain unit. Thus, the available resources include all frequency domain resources configured in the time domain unit. Correspondingly, within the time domain unit, the network device can schedule the terminal to perform downlink transmission on all frequency domain resources configured in the time domain unit.
[0203] In one example, when the first transmission direction of the subband and the second transmission direction of the time domain unit in which the subband is located are different, the terminal can determine that the frequency domain resources available for communication in the first transmission direction in the time domain unit include the subband.
[0204] For example, if the first transmission direction is uplink and the second transmission direction is downlink, the terminal can determine that the first and second transmission directions are different, and therefore can determine that only the uplink subband can be used for uplink transmission in the time domain unit. Correspondingly, the network device can only schedule the terminal to perform uplink transmission in the uplink subband within the time domain unit.
[0205] For example, if the first transmission direction is uplink and the second transmission direction is flexible, the terminal can determine that the first and second transmission directions are different, and therefore can determine that only the uplink subband can be used for uplink transmission in the time domain unit. Correspondingly, the network device can only schedule the terminal to perform uplink transmission in the uplink subband within the time domain unit.
[0206] For example, if the first transmission direction is downlink and the second transmission direction is uplink, the terminal can determine that the first and second transmission directions are different, and therefore can determine that only the downlink subband can be used for downlink transmission in the time domain unit. Correspondingly, the network device can only schedule the terminal to perform downlink transmission in the downlink subband within the time domain unit.
[0207] For example, if the first transmission direction is downlink and the second transmission direction is flexible, the terminal can determine that the first and second transmission directions are different, and therefore can determine that only the downlink subband can be used for downlink transmission in the time domain unit. Correspondingly, the network device can only schedule the terminal to perform downlink transmission in the downlink subband within the time domain unit.
[0208] In one example, the network device sends the time-domain unit configuration information to the terminal, including:
[0209] Send the first semi-static signaling to the terminal.
[0210] Then, the terminal determines the second transmission direction of the time domain unit where the sub-band is located based on the first semi-static signaling.
[0211] For example, a network device can configure a time-division duplex (TDM) structure for a terminal using a first semi-static signaling. The TDM structure can indicate the transmission direction of one or more time-domain units configured for the terminal, allowing the terminal to determine the transmission direction of the time-domain units based on the TDM structure. For instance, the TDM structure configured for the terminal can indicate the transmission direction of at least one time-domain unit in the terminal's time-domain resources.
[0212] Optionally, the network device may also send the time-domain unit configuration information to the terminal in the following ways:
[0213] After sending the first semi-static signaling to the terminal, a second semi-static signaling or dynamic indication is also sent to the terminal.
[0214] Then, the terminal determines the second transmission direction of the time domain unit where the sub-band is located based on the first semi-static signaling and the second semi-static signaling or dynamic indication.
[0215] For example, the time-division duplex structure configured for the terminal by the network device through the first semi-static signaling can be adjusted. For instance, after configuring the first time-division duplex structure for the terminal through the first semi-static configuration, the network device can adjust the time-division duplex structure by sending the second semi-static signaling to the terminal, or by sending dynamic indication information to the terminal.
[0216] It should be noted that after the network device sends the configuration information of the time domain unit and the configuration information of the subband to the terminal, the network device can also determine the first transmission direction of the subband configured for the terminal and the second transmission direction of the time domain unit where the subband is located, based on the configuration information of the time domain unit and the configuration information of the subband.
[0217] For example, if the first transmission direction is uplink and the second transmission direction is uplink, the network device can determine that the first transmission direction and the second transmission direction are the same. Within the time domain unit, the network device can schedule the terminal to perform uplink transmission on all frequency domain resources configured in the time domain unit.
[0218] For example, if the first transmission direction is downlink and the second transmission direction is downlink, the network device can determine that the first transmission direction and the second transmission direction are the same. Within the time domain unit, the network device can schedule the terminal to perform downlink transmission on all frequency domain resources configured in the time domain unit.
[0219] For example, if the first transmission direction is uplink and the second transmission direction is downlink, the network device can determine that the first transmission direction and the second transmission direction are different. Within the time domain unit, the network device can only schedule the terminal to perform uplink transmission on the uplink subband.
[0220] For example, if the first transmission direction is uplink and the second transmission direction is flexible, the network device can determine that the first transmission direction and the second transmission direction are different. Within the time domain unit, the network device can only schedule the terminal to perform uplink transmission on the uplink subband.
[0221] For example, if the first transmission direction is downlink and the second transmission direction is uplink, the network device can determine that the first transmission direction and the second transmission direction are different. Within the time domain unit, the network device can only schedule the terminal to perform downlink transmission on the downlink subband.
[0222] For example, if the first transmission direction is downlink and the second transmission direction is flexible, the network device can determine that the first transmission direction and the second transmission direction are different. Within the time domain unit, the network device can only schedule the terminal to perform downlink transmission on the downlink subband.
