[0002] Time Division Duplex (TDD) systems are widely used in mobile communication systems such as 5G systems. In a TDD system, a frame structure is divided into a DL (Down Link) slot, a UL (Up Link) slot, and an S (Special) slot. A DL slot includes multiple DL symbols, and downlink data is processed in the time domain resources corresponding to these DL symbols. A UL slot includes multiple UL symbols, and uplink data is processed in the time domain resources corresponding to these UL symbols. An S slot includes at least one F (Flexible) symbol. The F symbol may be used for DL, i.e., downlink data is processed in the time domain resources corresponding to the F symbol. The F symbol may be used for UL, i.e., uplink data is processed in the time domain resources corresponding to the F symbol. The F symbol may be used for a GP (Guard Period), i.e., a guard period for switching between uplink and downlink is performed in the time domain resources corresponding to the F symbol.

[0012] The terms used in the embodiments of the present invention are not intended to limit the present invention but merely to describe specific embodiments. As used in the embodiments and claims of the present invention, the singular forms "a," "the," and "the" are also intended to include the plural form unless the context clearly indicates otherwise. As used herein, the term "and / or" should be understood to mean any and all possible combinations including one or more of the associated listed items.

[0013] In the examples herein, terms such as "first," "second," and "third" may be used to describe various pieces of information, but it should be understood that these pieces of information should not be limited to these terms. These terms are used only to distinguish between pieces of information of the same type. For example, first information may be referred to as "second information," and similarly, second information may be referred to as "first information" without departing from the scope of the present invention. Furthermore, depending on the context, the word "if" may be interpreted as "when," "when," or "in response to determining."

[0014] In a TDD (Time Division Duplex) system, the frame structure is divided into a DL (Down Link) slot, an UL (Up Link) slot, and an S (Special) slot. A DL slot includes multiple DL symbols, and downlink data is processed in the time domain resources corresponding to these DL symbols. A UL slot includes multiple UL symbols, and uplink data is processed in the time domain resources corresponding to these UL symbols. An S slot includes at least one F (Flexible) symbol. The F symbol may be used for DL, UL, or GP (Guard Period). Currently, TDD systems can operate in HD (Half Duplex) mode, i.e., at the same time, the same time domain resource can only be used for UL or DL.

[0015] In order to use time domain resources more flexibly and improve resource utilization, the TDD system needs to use the same time domain resources simultaneously for UL and DL, that is, uplink data and downlink data are processed simultaneously in the same time domain resource, i.e., FD mode.

[0016] In a TDD system, once the frame structure is determined, user terminals can transmit and receive data based on the frame structure. The frame structure is divided into DL slots, UL slots, and S slots. In FD mode, the base station device and user terminals can also obtain the frame structure. For user terminals using HD mode, the base station device schedules user terminal transmission and reception based on the frame structure. For user terminals using FD mode, the base station device schedules user terminal transmission, reception, or simultaneous transmission and reception based on the frame structure.

[0017] As described above, the base station apparatus sets the frame structure for FD mode and notifies the user terminal of the frame structure for FD mode, allowing the user terminal to know the current frame structure and accurately transmit and receive data. From another perspective, after knowing the frame structure for FD mode, the user terminal can know the current possible interference between user terminals, and thereby can employ some interference cancellation techniques to reduce interference from other user terminals and improve communication reliability.

[0018] In one embodiment of the present invention, a TDD frame structure configuration method is provided to support FD mode in a TDD system. The frame structure configured for FD mode indicates UL resources, DL resources, and FD resources. The frame structure includes a DL slot, a UL slot, and an S slot. The DL slot includes multiple DL symbols, and downlink data is processed in the time domain resources corresponding to these DL symbols. The UL slot includes multiple UL symbols, and uplink data is processed in the time domain resources corresponding to these UL symbols. The S slot includes at least one F symbol. The F symbol may be used for FD, DL, UL, or GP. When the F symbol is used for FD, it means that the F symbol is used for uplink data and downlink data, and uplink data and downlink data can be processed simultaneously. When the F symbol is used for DL, it means that the F symbol is used for downlink data, and downlink data can be processed. When the F symbol is used for UL, it means that the F symbol is used for uplink data, and uplink data can be processed. When the F symbol is used for GP, it means that the F symbol is used for uplink data, and uplink data can be processed. When the F symbol is used for GP, it functions as a guard time for switching between uplink and downlink.

[0019] In one example, when F symbols are used for FD, some frequency domain resources of FD are used for UL, other frequency domain resources are used for DL, and some intermediate frequency domain resources can function as guard intervals for uplink and downlink, thus avoiding the occurrence of inter-subband interference.

[0020] First, the following solutions will be described.

[0021] 1. Currently, in 5G systems, the TDD frame structure is divided into UL slots, DL slots, and S slots according to slots. The S slot includes an F symbol, which may be used for UL, DL, or GP. The frame structure may be signaled to a user equipment (UE) via TDD-UL-DL-ConfigCommon (uplink and downlink common configuration) / TDD-UL-DL-ConfigDedicated (uplink and downlink dedicated configuration). Up to two frame structure patterns may be configured in TDD-UL-DL-ConfigCommon. In each pattern, the frame structure period, and each slot and each symbol (DL symbol, UL symbol, or F symbol) within the period may be configured to determine the frame structure. Here, as shown in FIG. 1, an example of a frame structure has an uplink / downlink ratio of 1:4, the S slot is slot 3, and symbols #10 and #11 are configured as F symbols and used for GP for uplink and downlink switching.

[0022] In TDD-UL-DL-ConfigDedicated, the symbol set as the F symbol in TDD-UL-DL-ConfigCommon may be changed to the DL symbol or the UL symbol.

[0023] 2. In 5G systems, the configuration of the TDD frame structure can be completed by a slot format indicator (SFI). First, multiple slot format combinations (SFCs) are defined by the SFI in higher layer signaling. For example, a base station device may select slot formats that meet service requirements and add these slot formats to the SFC.

[0024] For some slot formats, see Table 1. D represents DL symbol, U represents UL symbol, and F represents F symbol. Each SFC is identified by a fixed ID (identification) and includes one or more slot format types. After SFI configuration is complete, the base station device transmits multiple slot format combinations to the user terminal via RRC (Radio Resource Control) signaling.

[0025] [Table 1]

[0026] Next, after configuring multiple slot format combinations by RRC signaling, the base station device may notify the user terminal of the index of the SFC currently being used in DCI format 2_0 by periodic PDCCH (Physical Downlink Control Channel). A partial information structure of DCI format 2_0 is as follows: The following information is transmitted by means of the DCI format 2_0 with CRC scrambled by SFI-RNTI: - If the higher layer parameter slotFormatCombToAddModList is configured, - Slot format indicator 1, Slot format indicator 2, …, Slot format indicator N, - ……

[0027] After correctly receiving the DCI format 2_0 information, the user terminal determines the slot format for each slot within a certain period according to the specified SFC index value. In this way, the base station apparatus and the user terminal complete the frame structure configuration through dynamic instruction and can perform normal uplink / downlink data transmission.

[0028] The technical solution of the present invention will be described below with reference to examples.

[0029] An embodiment of the present invention provides a TDD frame structure setting method applied to a base station device, as shown in Figure 2, which is a flowchart of the TDD frame structure setting method, and may include the following steps:

[0030] In step 201, an operation mode corresponding to the base station device is determined. The operation mode is an FD enable mode or an FD disable mode. When the operation mode is the FD enable mode, the F symbol in the slot is permitted to be used for FD, DL, UL, or GP, and when the operation mode is the FD disable mode, the F symbol in the slot is permitted to be used for DL, UL, or GP.

[0031] In step 202, if the operating mode is the FD enable mode, send FD enable mode indication information to the user terminal, thereby causing the user terminal to enable the FD mode for the user terminal according to the FD enable mode indication information.

[0032] In step 203, if the operation mode is FD enabled mode, when F symbols in a slot are used for FD, uplink data and downlink data can be processed simultaneously in the time domain resource corresponding to the F symbols.

[0033] In one example, transmitting the FD enable mode indication information to the user terminal may include transmitting a system broadcast message to which the FD enable mode indication information is attached to the user terminal.

[0034] If the system broadcast message is a Master Information Block (MIB) message, the FD enable mode indication information may be indicated by a spare field (Spare) of the MIB message, or the MIB message may include a full duplex enable field (FD Enabled) and the FD enable mode indication information may be indicated by the full duplex enable field of the MIB message. If the FD enable mode indication information is added to the MIB message, the effective time for which the FD mode is enabled may include, but is not limited to, the slot following the slot in which the MIB message is transmitted, or the Mth slot after the slot in which the MIB message is transmitted, or the first slot of the frame following the frame in which the MIB message is transmitted, or the first slot of the period following the period in which the MIB message is transmitted. Here, M is a fixed value agreed upon between the base station device and the user terminal, and M is a positive integer.

[0035] When the system broadcast message is a System Information Block (SIB) message, the FD enable mode indication information may be indicated by an uplink / downlink common configuration message (TDD-UL-DL-ConfigCommon) in the SIB message, or the SIB message may include a full duplex enable field and the FD enable mode indication information may be indicated by the full duplex enable field in the SIB message. When the FD enable mode indication information is added to the SIB message, the effective time for which the FD mode is enabled may include, but is not limited to, the slot following the slot in which the SIB message is transmitted, or the Mth slot after the slot in which the SIB message is transmitted, or the first slot of the frame following the frame in which the SIB message is transmitted, or the first slot of the period following the period in which the SIB message is transmitted. Here, M is a fixed value agreed upon between the base station apparatus and the user terminal, and M is a positive integer.

[0036] In one example, transmitting the FD enable mode indication information to the user terminal may include transmitting an RRC reconfiguration message to which the FD enable mode indication information is attached to the user terminal.

[0037] When FD enable mode indication information is added to the RRC reconfiguration message, the RRC reconfiguration message may include a full duplex enable field, and the FD enable mode indication information may be indicated by the full duplex enable field of the RRC reconfiguration message. When FD enable mode indication information is added to the RRC reconfiguration message, the effective time for which the FD mode is enabled may include, but is not limited to, the slot next to the slot in which an RRC reconfiguration complete message corresponding to the RRC reconfiguration message is received, or the M-th slot after the slot in which an RRC reconfiguration complete message corresponding to the RRC reconfiguration message is received. Here, M is a fixed value agreed upon between the base station apparatus and the user terminal, and M is a positive integer.

[0038] Before step 203, the method may include determining a target frame structure and transmitting an uplink / downlink common configuration message to a user terminal, the target frame structure including frame structure parameters corresponding to the target frame structure, thereby causing the user terminal to determine the target frame structure based on the frame structure parameters; and performing data processing based on the target frame structure. Here, the target frame structure includes multiple slots, each slot including multiple symbols, the symbols being F symbols, DL symbols, or UL symbols. Regarding step 203, when performing data processing based on the target frame structure, if the F symbol in a slot is used for forward link (FD), uplink data and downlink data can be simultaneously processed using time domain resources corresponding to the F symbol. If the F symbol in a slot is used for DL, downlink data is processed using time domain resources corresponding to the F symbol. If the F symbol in a slot is used for UL, uplink data is processed using time domain resources corresponding to the F symbol.

[0039] In one example, transmitting the FD enable mode indication information to the user terminal may include transmitting a slot format indication message (e.g., carried by RRC signaling) to the user terminal, with the FD enable mode indication information attached to the slot format indication message. Here, attaching the FD enable mode indication information to the slot format indication message may include attaching the FD enable mode indication information to the slot format indication message if the slot format indication message includes a full duplex slot format combination field.

[0040] If the slot format instruction message includes a full-duplex slot format combination field, a combination identifier corresponding to at least one slot format combination is added to the full-duplex slot format combination field. After sending the slot format instruction message to the user terminal, a target slot format combination may be determined, and the combination identifier corresponding to the target slot format combination may be sent to the user terminal via a DCI message, so that the user terminal determines the target slot format combination based on the combination identifier corresponding to the target slot format combination.

[0041] When FD enable mode indication information is added to the slot format indication message, the effective time for which the FD mode is enabled may include, but is not limited to, the slot in which the DCI message is transmitted.

[0042] Here, before step 203, a target frame structure may be further determined based on the target slot format combination. The target frame structure includes multiple slots, each slot including multiple symbols, where the symbols are F symbols, DL symbols, or UL symbols. Data processing may also be performed based on the target frame structure. Regarding step 203, when data processing is performed based on the target frame structure, if the F symbol in a slot is used for FD, uplink data and downlink data can be simultaneously processed in the time domain resource corresponding to the F symbol. If the F symbol in a slot is used for DL, downlink data is processed in the time domain resource corresponding to the F symbol. If the F symbol in a slot is used for UL, uplink data is processed in the time domain resource corresponding to the F symbol.

[0043] An embodiment of the present invention provides a TDD frame structure setting method applicable to a user terminal supporting FD mode. Figure 3 is a flowchart of the TDD frame structure setting method, which may include the following steps:

[0044] In step 301, FD enable mode indication information is received from a base station device. The FD enable mode indication information is transmitted by the base station device to a user terminal when the operation mode of the base station device is the FD enable mode.

[0045] In step 302, the FD mode is enabled for the user terminal based on the FD enable mode indication information.

[0046] Here, after enabling the FD mode for the user terminal, the user terminal expects the F symbols in a slot to be used for FD, DL, UL, or GP. If the FD mode is not enabled for the user terminal, the user terminal expects the F symbols in a slot to be used for DL, UL, or GP. When the F symbols in a slot are used for DL, downlink data is processed in the time domain resource corresponding to the F symbols, and when the F symbols in a slot are used for UL, uplink data is processed in the time domain resource corresponding to the F symbols.

[0047] In step 303, after enabling the FD mode for the user terminal, when F symbols in a slot are used for FD, uplink data and downlink data can be processed simultaneously in the time domain resource corresponding to the F symbols.

[0048] In one example, the step of receiving FD enable mode indication information from the base station device may include the step of receiving a system broadcast message from the base station device to which the FD enable mode indication information is attached.

[0049] If the system broadcast message is an MIB message, the FD enable mode indication information may be indicated by a spare field in the MIB message, or the MIB message may include a full duplex enable field and the FD enable mode indication information may be indicated by the full duplex enable field in the MIB message. If the FD enable mode indication information is added to the MIB message, the effective time for the user terminal to enable the FD mode may include, but is not limited to, the slot following the slot in which the MIB message is received, or the Mth slot after the slot in which the MIB message is received, or the first slot of the frame following the frame in which the MIB message is received, or the first slot of the period following the period in which the MIB message is received. Here, M is a fixed value agreed upon between the base station device and the user terminal, and M is a positive integer.

[0050] When the system broadcast message is an SIB message, the FD enable mode indication information may be indicated by an uplink / downlink common configuration message of the SIB message, or the SIB message may include a full duplex enable field and the FD enable mode indication information may be indicated by the full duplex enable field of the SIB message. When the FD enable mode indication information is added to the SIB message, the effective time for the user terminal to enable the FD mode may include, but is not limited to, the slot following the slot in which the SIB message is received, or the Mth slot after the slot in which the SIB message is received, or the first slot of the frame following the frame in which the SIB message is received, or the first slot of the period following the period in which the SIB message is received. Here, M is a fixed value agreed upon between the base station apparatus and the user terminal, and M is a positive integer.

[0051] In one example, the step of receiving FD enable mode indication information from the base station device may include the step of receiving an RRC reconfiguration message to which the FD enable mode indication information is added from the base station device.

[0052] When FD enable mode indication information is added to the RRC reconfiguration message, the RRC reconfiguration message may include a full duplex enable field, and the FD enable mode indication information may be indicated by the full duplex enable field of the RRC reconfiguration message. When FD enable mode indication information is added to the RRC reconfiguration message, the effective time for the user terminal to enable the FD mode may include, but is not limited to, the slot next to the slot in which an RRC reconfiguration complete message corresponding to the RRC reconfiguration message is transmitted, or the M-th slot after the slot in which an RRC reconfiguration complete message corresponding to the RRC reconfiguration message is transmitted, where M is a fixed value agreed upon between the base station device and the user terminal, and M is a positive integer.

[0053] Before step 303, an uplink / downlink common configuration message may be received from the base station device. The uplink / downlink common configuration message includes frame structure parameters corresponding to the target frame structure. The target frame structure may also be determined based on the frame structure parameters. The target frame structure includes multiple slots, each slot including multiple symbols, which may be F symbols, DL symbols, or UL symbols. Data processing may also be performed based on the target frame structure.

[0054] In step 303, when data processing is performed based on the target frame structure, if the F symbols in a slot are used for FD, uplink data and downlink data can be processed simultaneously in the time domain resource corresponding to the F symbols. If the F symbols in a slot are used for DL, downlink data is processed in the time domain resource corresponding to the F symbols. If the F symbols in a slot are used for UL, uplink data is processed in the time domain resource corresponding to the F symbols.

[0055] In one example, receiving the FD enable mode indication information from the base station device may include receiving a slot format indication message (e.g., carried by RRC signaling) from the base station device, with the FD enable mode indication information attached to the slot format indication message. Here, adding the FD enable mode indication information to the slot format indication message may include adding the FD enable mode indication information to the slot format indication message if the slot format indication message includes a full duplex slot format combination field.

[0056] If the slot format instruction message includes a full-duplex slot format combination field, the user terminal may analyze a combination identifier corresponding to at least one slot format combination from the full-duplex slot format combination field. After receiving the slot format instruction message from the base station device, the user terminal may receive a DCI message from the base station device, analyze a combination identifier corresponding to a target slot format combination from the DCI message, and determine a target slot format combination based on the combination identifier corresponding to the target slot format combination.

[0057] If FD enable mode indication information is added to the slot format indication message, the effective time for the user terminal to enable the FD mode may include the slot in which the DCI message is received.

[0058] Here, before step 303, a target frame structure may be determined based on the target slot format combination. The target frame structure includes multiple slots, each of which includes multiple symbols, and the symbols are F symbols, DL symbols, or UL symbols. Data processing may also be performed based on the target frame structure. Regarding step 303, when data processing is performed based on the target frame structure, if the F symbol in a slot is used for FD, uplink data and downlink data can be simultaneously processed in the time domain resource corresponding to the F symbol. If the F symbol in a slot is used for DL, downlink data is processed in the time domain resource corresponding to the F symbol. If the F symbol in a slot is used for UL, uplink data is processed in the time domain resource corresponding to the F symbol.

[0059] An embodiment of the present invention provides a TDD frame structure setting method applicable to a user terminal that does not support FD mode. Figure 4 is a flowchart of the TDD frame structure setting method, which may include the following steps:

[0060] In step 401, FD enable mode indication information is received from a base station device. The FD enable mode indication information is transmitted by the base station device to a user terminal when the operation mode of the base station device is the FD enable mode.

[0061] In step 402, the FD enable mode indication information is ignored. That is, the FD mode is not enabled for the user terminal based on the FD enable mode indication information. The user terminal expects that F symbols in a slot are used for DL, UL, or GP. When the F symbols in a slot are used for DL, downlink data is processed in the time domain resource corresponding to the F symbols, and when the F symbols in a slot are used for UL, uplink data is processed in the time domain resource corresponding to the F symbols.

[0062] As can be seen from the above technical solutions, the operation modes corresponding to the base station device can be divided into FD enabled mode and FD disabled mode, and when the operation mode is FD enabled mode, the F symbol in the slot is allowed to be used for FD, that is, the function of the F symbol is extended to function as an FD symbol. In addition, when the F symbol in the slot is used for FD, the uplink data and the downlink data can be simultaneously processed in the time domain resource corresponding to the F symbol, and thus the uplink data and the downlink data can be simultaneously processed in the same time domain resource, thereby more effectively utilizing the time domain resource, improving resource utilization, improving network coverage and network capacity, and reducing the uplink transmission delay, for example, reducing the transmission delay.

[0063] The above technical solution of the present invention will be described below with reference to an embodiment.

[0064] This embodiment provides a TDD frame structure configuration method, which enables the frame structure to be applied to FD mode based on support for the TDD system. In this embodiment, a new frame structure is configured for FD mode. The frame structure includes multiple slots, and each slot includes multiple symbols, which may be F symbols, DL symbols, or UL symbols. The base station apparatus and the user terminal process downlink data using time domain resources corresponding to DL symbols, and process uplink data using time domain resources corresponding to UL symbols.

[0065] Regarding the F symbol, when the base station device enables the FD mode, i.e., when the base station device allows simultaneous processing of uplink data and downlink data, the F symbol is used for FD, DL, UL, or GP. When the F symbol is used for FD, uplink data and downlink data can be processed simultaneously; when the F symbol is used for DL, downlink data can be processed; when the F symbol is used for UL, uplink data can be processed; when the F symbol is used for GP, it can function as a guard for switching between uplink and downlink. When the base station device turns off (disables) the FD mode, i.e., when the base station device does not allow simultaneous processing of uplink data and downlink data, the F symbol is used for DL, UL, or GP. When the F symbol is used for DL, downlink data can be processed; when the F symbol is used for UL, uplink data can be processed; when the F symbol is used for GP, it can function as a guard for switching between uplink and downlink.

[0066] The reason why the F symbol is used for GP is that it provides a guard for switching between uplink and downlink in the frame structure of a TDD system. When a base station operates in FD mode, it transmits and receives using separate antennas and radio frequency circuits, eliminating the need for a GP symbol to provide a guard for switching between uplink and downlink. For FD mode user terminals, the operation method is the same as that of a base station, and it is not necessary to provide a guard for switching between uplink and downlink using a GP symbol. For HD mode user terminals, sufficient time is required for switching between transmission and reception in the radio frequency, i.e., a GP symbol is used to provide a guard for switching between uplink and downlink. For these reasons, to support HD mode user terminals, the FD mode frame structure still uses a GP symbol, and therefore the F symbol is allowed to be used for GP.

[0067] In this embodiment, the TDD frame structure configuration method may include the following steps:

[0068] In step S11, the base station device determines an operation mode corresponding to the base station device. The operation mode is an FD enabled mode or an FD disabled mode. For example, the operation mode may be set in the base station device according to service requirements, and this process is not limited. If the operation mode corresponding to the base station device is the FD enabled mode, the symbols in the slot are permitted to be F symbols, DL symbols, or UL symbols, and the F symbols in the slot are permitted to be used for FD, DL, UL, or GP. If the operation mode corresponding to the base station device is the FD disabled mode, the symbols in the slot are permitted to be F symbols, DL symbols, or UL symbols, and the F symbols in the slot are permitted to be used for DL, UL, or GP.

[0069] In step S12, if the operation mode is the FD enable mode, the base station device transmits a MIB message to the user terminal. The MIB message includes FD enable mode indication information. Alternatively, if the operation mode is the FD disable mode, the base station device does not transmit the FD enable mode indication information to the user terminal by the MIB message.

[0070] When system broadcasting is used, the FD enable mode indication information may be added to the MIB message, that is, the FD enable mode indication information may be broadcast by the MIB message.

[0071] For example, the FD enable mode indication information may be indicated by a spare field (spare) of the MIB message. That is, the spare field of the MIB message may be set to a preset value (which may be set based on experience). When the spare field is the preset value, the FD enable mode indication information is indicated.

[0072] Regarding the method in which FD enable mode indication information is indicated by a spare field, an example of an MIB message is as follows: MIB ::= SEQUENCE { ... spare BIT STRING (SIZE (1)) }

[0073] In the above MIB message, "spare" is a spare field, and the value of the spare field is SIZE(1), which indicates FD enable mode indication information. Of course, this is just one example of a spare field.

[0074] In another example, a full duplex enable field (fullDuplexEnabled) may be added to the MIB message, and the FD enable mode indication information may be indicated by the full duplex enable field of the MIB message. That is, when the MIB message includes the full duplex enable field, the FD enable mode indication information is indicated.

[0075] Regarding the method of adding a full duplex enable field, an example of the MIB message is as follows: MIB ::= SEQUENCE { ... fullDuplexEnabled ENUMERATED {enabled} OPTIONAL, }

[0076] In the above MIB message, fullDuplexEnabled indicates the full duplex enable field. Obviously, if the MIB message contains fullDuplexEnabled, it indicates the FD enable mode indication information.

[0077] In the above example of the MIB message, the spare field of the MIB message is replaced with fullDuplexEnabled. Alternatively, the spare field may be reserved and a new field fullDuplexEnabled may be added, and the FD enable mode indication information may be indicated by the added fullDuplexEnabled.

[0078] When FD enable mode indication information is added to the spare field or full duplex enable field of the MIB message, the valid time of the FD mode can be specified. For example, the valid time of the FD mode enabled can be determined by adopting the following method:

[0079] Method 1: The slot following the slot in which the MIB message is transmitted, i.e., the slot following the transmission slot of the MIB message. In other words, the FD mode is enabled in the slot following the slot in which the MIB message is transmitted. As shown in Figure 5, the MIB message is transmitted once every eight frames, i.e., once every 80 ms. As shown in Figure 5, the MIB message is transmitted in slot 0 of the Nth frame and the (N+8)th frame. Obviously, the slots in which the MIB message is transmitted are slot 0 of the Nth frame and the (N+8)th frame, so the FD mode is enabled in slot 1 of the Nth frame.

[0080] Method 2: The Mth slot after the slot in which the MIB message is transmitted, i.e., the Mth slot after the transmission slot of the MIB message. In other words, the FD mode is enabled in the Mth slot after the slot in which the MIB message is transmitted.

[0081] Here, M is a fixed value agreed upon between the base station apparatus and the user terminal, and M is a positive integer. For example, M is a fixed value agreed upon between the base station apparatus and the user terminal based on the capabilities of the user terminal, and the base station apparatus does not notify the user terminal of the value of M by specific signaling, and M is, for example, 4, 5, 6, 7, etc.

[0082] As shown in Figure 5, taking M=5 as an example, the slot in which the MIB message is transmitted is slot 0 of the Nth frame, so the FD mode is enabled in slot 5 of the Nth frame (the fifth slot after slot 0).

[0083] Method 3: The first slot of the frame following the frame in which the MIB message is transmitted, i.e., the first slot of the first frame after the transmission frame of the MIB message. In other words, the FD mode is enabled in the first slot of the frame following the frame in which the MIB message is transmitted. As shown in Figure 5, the slot in which the MIB message is transmitted is slot 0 of the Nth frame, so the FD mode is enabled in slot 0 of the (N+1)th frame.

[0084] Method 4: The first slot of the cycle following the cycle in which the MIB message is transmitted, i.e., the first slot of the first cycle after the cycle in which the MIB message is transmitted. In other words, the FD mode is enabled in the first slot of the cycle following the cycle in which the MIB message is transmitted. As shown in Figure 5, the slot in which the MIB message is transmitted is slot 0 of the Nth frame, so the FD mode is enabled in slot 0 of the (N+8)th frame.

[0085] In step S13, the user terminal receives a MIB message from the base station device. The MIB message may include FD enable mode indication information. For example, after receiving the MIB message, if the spare field (spare) of the MIB message indicates FD enable mode indication information, the user terminal determines that the FD enable mode indication information has been received from the base station device. Alternatively, if the MIB message includes a full duplex enable field (fullDuplexEnabled), the user terminal determines that the FD enable mode indication information has been received from the base station device.

[0086] In step S14, the user terminal enables the FD mode for the user terminal based on the FD enable mode indication information.

[0087] When the user terminal determines that it has received FD enable mode indication information from the base station device, it may enable FD mode for the user terminal. After enabling FD mode for the user terminal, the user terminal expects the symbols in the slot to be F symbols, DL symbols, or UL symbols, and also expects the F symbols in the slot to be used for FD, DL, UL, or GP.

[0088] When enabling the FD mode for a user terminal, the effective time of the FD mode may be specified. For example, the following method is adopted to determine the effective time of enabling the FD mode for a user terminal:

[0089] Method 1: The slot following the slot in which the MIB message is received, that is, the slot following the reception slot of the MIB message. In other words, the FD mode is enabled in the slot following the slot in which the MIB message is received.

[0090] Method 2: The Mth slot after the slot in which the MIB message is received, i.e., the Mth slot after the reception slot of the MIB message. In other words, the FD mode is enabled in the Mth slot after the slot in which the MIB message is received. M is a fixed value agreed upon between the base station apparatus and the user terminal, and M is a positive integer.

[0091] Method 3: The first slot of the frame following the frame in which the MIB message is received, i.e., the first slot of the frame following the frame in which the MIB message is received. In other words, the FD mode is enabled in the first slot of the frame following the frame in which the MIB message is received.

[0092] Method 4: The first slot of the cycle following the cycle in which the MIB message is received, i.e., the first slot of the cycle following the cycle in which the MIB message is received. In other words, the FD mode is enabled in the first slot of the cycle following the cycle in which the MIB message is received.

[0093] The above methods 1 to 4 are similar to the methods shown in FIG. 5, and therefore a description thereof will be omitted here.

[0094] In one example, if FD mode is not enabled for a user terminal, the user terminal expects the symbols in a slot to be F symbols, DL symbols, or UL symbols, and expects the F symbols in a slot to be used for DL, UL, or GP.

[0095] In step S15, the base station device determines a target frame structure, which includes a plurality of slots, each of which includes a plurality of symbols, and the symbols may be F symbols, DL symbols, or UL symbols.

[0096] The target frame structure is a frame structure for performing data processing (e.g., data transmission and / or data reception). The base station device determines the target frame structure and performs data processing based on the target frame structure. The user terminal determines the target frame structure and performs data processing based on the target frame structure. The target frame structure determined by the base station device is the same as the target frame structure determined by the user terminal.

[0097] In step S16, the base station device transmits an uplink / downlink common configuration message to the user terminal, the uplink / downlink common configuration message including a frame structure parameter corresponding to the target frame structure, the frame structure parameter being used to indicate the target frame structure.

[0098] In step S17, the user terminal receives the uplink / downlink common configuration message, analyzes the frame structure parameters from the uplink / downlink common configuration message, and determines a target frame structure based on the frame structure parameters.

[0099] In step S18, the base station apparatus and the user terminal perform data processing based on the target frame structure.

[0100] For example, when the operation mode corresponding to the base station device is an FD-enabled mode and the FD mode is enabled for the user terminal, the symbols in the target frame structure may be F symbols, DL symbols, or UL symbols. When performing data processing based on the target frame structure, if the symbols in a slot are DL symbols, the base station device processes downlink data using time domain resources corresponding to the DL symbols, and the user terminal processes downlink data using time domain resources corresponding to the DL symbols. If the symbols in a slot are UL symbols, the base station device processes uplink data using time domain resources corresponding to the UL symbols, and the user terminal processes uplink data using time domain resources corresponding to the UL symbols.

[0101] Furthermore, if the symbol in the slot is an F symbol, when the F symbol in the slot is used for FD, the base station device can simultaneously process uplink data and downlink data using the time domain resource corresponding to the F symbol, and the user terminal can simultaneously process uplink data and downlink data using the time domain resource corresponding to the F symbol.

[0102] When F symbols in a slot are used for DL, the base station apparatus processes downlink data using time domain resources corresponding to the F symbols, and the user terminal processes downlink data using time domain resources corresponding to the F symbols.

[0103] When F symbols in a slot are used for UL, the base station apparatus processes uplink data using time domain resources corresponding to the F symbols, and the user terminal processes uplink data using time domain resources corresponding to the F symbols.

[0104] In another example, when the operation mode corresponding to the base station device is FD disabled mode and the FD mode is not enabled for the user terminal, the symbols of the target frame structure may be F symbols, DL symbols, or UL symbols. When performing data processing based on the target frame structure, if the symbols in a slot are DL symbols, the base station device processes downlink data using time domain resources corresponding to the DL symbols, and the user terminal processes downlink data using time domain resources corresponding to the DL symbols. If the symbols in a slot are UL symbols, the base station device processes uplink data using time domain resources corresponding to the UL symbols, and the user terminal processes uplink data using time domain resources corresponding to the UL symbols.

[0105] Furthermore, if the symbol in a slot is an F symbol, when the F symbol in the slot is used for DL, the base station apparatus processes downlink data using the time domain resource corresponding to the F symbol, and the user terminal processes the downlink data using the time domain resource corresponding to the F symbol. When the F symbol in the slot is used for UL, the base station apparatus processes uplink data using the time domain resource corresponding to the F symbol, and the user terminal processes the uplink data using the time domain resource corresponding to the F symbol.

[0106] In the above example, steps S11 to S18 are targeted at user terminals that support FD mode. For user terminals that do not support FD mode, in steps S13 and S14, when receiving an MIB message from the base station apparatus, the user terminal ignores the FD enable mode indication information, i.e., does not enable FD mode for the user terminal based on the FD enable mode indication information. The user terminal expects the symbol in the slot to be an F symbol, DL symbol, or UL symbol, and expects the F symbol in the slot to be used for DL, UL, or GP. In step S18, when the user terminal processes data based on the target frame structure, if the symbol in the slot is an F symbol, and the F symbol in the slot is used for DL, UL, or GP, the user terminal processes downlink data using time domain resources corresponding to the F symbol. If the F symbol in the slot is used for UL, the user terminal processes uplink data using time domain resources corresponding to the F symbol.

[0107] In the above example, if the operating mode corresponding to the base station device is FD enabled mode, the base station device flexibly schedules the F symbols according to service requirements and allows simultaneous transmission and reception using the F symbols.

[0108] For user terminals that do not support the FD mode, the user terminals do not expect the F symbol to be configured to simultaneously transmit uplink data and receive downlink data. For different user terminals (e.g., a first user terminal and a second user terminal), the base station apparatus configures the F symbol corresponding to the first user terminal to transmit uplink data, and configures the F symbol corresponding to the second user terminal (which is in the same position as the F symbol corresponding to the first user terminal) to receive downlink data. In this way, the base station apparatus can transmit uplink data and receive downlink data in the F symbol.

[0109] For user equipment that does not support FD mode, sufficient GP resources must be reserved for the user equipment to guard the uplink and downlink switching during the process of switching between DL data and UL data.

[0110] For user terminals that support the FD mode, the F symbol may be configured to transmit uplink data and receive downlink data simultaneously, i.e., the user terminal does not need to reserve GP resources and transmits uplink data and receives downlink data simultaneously.

[0111] In one example, the base station device may change the symbol set to the F symbol in TDD-UL-DL-ConfigCommon by TDD-UL-DL-ConfigDedicated, and set it to the DL symbol or the UL symbol. That is, after the symbol in the slot is set to the F symbol by TDD-UL-DL-ConfigCommon, the F symbol may be changed to the DL symbol or the UL symbol by TDD-UL-DL-ConfigDedicated.

[0112] In this case, for an F symbol configured as a DL symbol or UL symbol by TDD-UL-DL-ConfigDedicated, the user terminal does not expect that F symbol to be used for FD, while other unchanged F symbols may continue to be used for DL, UL, GP, or FD.

[0113] Another embodiment of the present invention provides a TDD frame structure setting method, where the frame structure includes a plurality of slots, each slot includes a plurality of symbols, and these symbols may be F symbols, DL symbols, or UL symbols. When the base station device enables the FD mode, the F symbols are used for FD, DL, UL, or GP, and when the base station device turns off the FD mode, the F symbols are used for DL, UL, or GP.

[0114] In this embodiment, the TDD frame structure configuration method may include the following steps:

[0115] In step S21, the base station device determines an operation mode corresponding to the base station device, which is either an FD enabled mode or an FD disabled mode.

[0116] In step S22, if the operation mode is the FD enable mode, the base station device transmits an SIB message to the user terminal. The SIB message includes FD enable mode indication information. Alternatively, if the operation mode is the FD disable mode, the base station device does not transmit the FD enable mode indication information to the user terminal by the SIB message.

[0117] When system broadcast is used, the FD enable mode indication information may be added to a SIB message. That is, the FD enable mode indication information may be broadcast by a SIB message. Here, the FD enable mode indication information may be broadcast by a SIBx message. SIBx represents any SIB. Considering that enabling the FD mode belongs to an important system configuration parameter, the FD enable mode indication information may be broadcast by a SIB1 message.

[0118] For example, the FD enable mode indication information is indicated by an uplink / downlink common configuration message (TDD-UL-DL-ConfigCommon) of an SIB message. Also, considering that the same system information as that of MIB and SIB1 is transmitted by servingCellConfigCommon, the FD enable mode indication information may be indicated in a common parameter present in both the serving cell common configuration and SIB1. The uplink / downlink common configuration message is a common parameter of the serving cell common configuration and SIB1, and can configure the frame structure, so the FD enable mode indication information is introduced by the uplink / downlink common configuration message.

[0119] For example, an example of an uplink / downlink common configuration message (TDD-UL-DL-ConfigCommon) is as follows: TDD-UL-DL-ConfigCommon ::= SEQUENCE { … fullDuplexEnabled ENUMERATED {enabled} OPTIONAL, ... }

[0120] Here, "fullDuplexEnabled" indicates FD enable mode indication information. That is, the FD enable mode indication information is indicated by adding "fullDuplex Enabled" to the uplink and downlink common configuration message.

[0121] In another example, a full duplex enable field (fullDuplexEnabled) may be added to the SIB message, and the FD enable mode indication information may be indicated by the full duplex enable field of the SIB message. That is, when the full duplex enable field is included in the SIB message, the FD enable mode indication information is indicated.

[0122] The newly introduced full duplex enable field in the SIB message is an optional field. If this field is not set, it indicates that the base station device does not enable FD mode. If the full duplex enable field is set to enabled, it indicates that the base station device enables FD mode, and the F symbol may be used for DL, UL, GP, or FD.

[0123] When FD enable mode indication information is added to the SIB message, the effective time for which FD mode is enabled may be clarified. For example, the following methods are used to determine the effective time for which FD mode is enabled. Method 1: The slot following the slot in which the SIB message is transmitted, i.e., the slot following the transmission slot of the SIB message. That is, FD mode is enabled in the slot following the slot in which the SIB message is transmitted. Method 2: The Mth slot after the slot in which the SIB message is transmitted, i.e., the Mth slot after the transmission slot of the SIB message. That is, FD mode is enabled in the Mth slot after the slot in which the SIB message is transmitted. M is a fixed value agreed upon between the base station apparatus and the user terminal, and M is a positive integer. Method 3: The first slot of the frame following the frame in which the SIB message is transmitted, i.e., the first slot of the first frame after the transmission frame of the SIB message. That is, FD mode is enabled in the first slot of the frame following the frame in which the SIB message is transmitted. Method 4: The first slot of the cycle following the cycle in which the SIB message is transmitted, i.e., the first slot of the first cycle after the transmission cycle of the SIB message. In other words, the FD mode is enabled in the first slot of the period following the period in which the SIB message is transmitted.

[0124] In step S23, the user terminal receives the SIB message from the base station device.

[0125] In step S24, if FD enable mode indication information is added to the SIB message, the user terminal enables the FD mode for the user terminal based on the FD enable mode indication information.

[0126] When enabling FD mode for a user terminal, the effective time for FD mode may be further clarified. For example, the following methods may be employed to determine the effective time for enabling FD mode for a user terminal. Method 1: The slot following the slot in which the SIB message is received, i.e., the slot following the slot in which the SIB message is received. That is, FD mode is enabled in the slot following the slot in which the SIB message is received. Method 2: The Mth slot after the slot in which the SIB message is received, i.e., the Mth slot after the slot in which the SIB message is received. That is, FD mode is enabled in the Mth slot after the slot in which the SIB message is received. M is a fixed value agreed upon between the base station apparatus and the user terminal, and M is a positive integer. Method 3: The first slot of the frame following the frame in which the SIB message is received, i.e., the first slot of the frame following the frame in which the SIB message is received. That is, FD mode is enabled in the first slot of the frame following the frame in which the SIB message is received. Method 4: The first slot of the cycle following the cycle in which the SIB message is received, i.e., the first slot of the cycle following the cycle in which the SIB message is received. In other words, the FD mode is enabled in the first slot of the cycle following the cycle in which the SIB message is received.

[0127] In step S25, the base station device determines a target frame structure, which includes a plurality of slots, each of which includes a plurality of symbols, and the symbols may be F symbols, DL symbols, or UL symbols.

[0128] In step S26, the base station device transmits an uplink / downlink common configuration message to the user terminal, the uplink / downlink common configuration message including a frame structure parameter corresponding to the target frame structure, the frame structure parameter being used to indicate the target frame structure.

[0129] In step S27, the user terminal receives the uplink / downlink common configuration message, analyzes the frame structure parameters from the uplink / downlink common configuration message, and determines a target frame structure based on the frame structure parameters.

[0130] In step S28, the base station apparatus and the user terminal perform data processing based on the target frame structure.

[0131] Another embodiment of the present invention provides a TDD frame structure setting method, where the frame structure includes a plurality of slots, each slot includes a plurality of symbols, and these symbols may be F symbols, DL symbols, or UL symbols. When the base station device enables the FD mode, the F symbols are used for FD, DL, UL, or GP, and when the base station device turns off the FD mode, the F symbols are used for DL, UL, or GP.

[0132] In this embodiment, the TDD frame structure configuration method may include the following steps:

[0133] In step S31, the base station device determines an operation mode corresponding to the base station device, which is either an FD enabled mode or an FD disabled mode.

[0134] In step S32, if the operation mode is the FD enable mode, the base station device transmits an RRC reconfiguration message to the user terminal. The RRC reconfiguration message includes FD enable mode indication information. Alternatively, if the operation mode is the FD disable mode, the base station device does not transmit the FD enable mode indication information to the user terminal in the RRC reconfiguration message.

[0135] For example, a full duplex enable field (fullDuplexEnabled) may be added to the RRC reconfiguration message, and the FD enable mode indication information may be indicated by the full duplex enable field of the RRC reconfiguration message. That is, when the full duplex enable field is included in the RRC reconfiguration message, the FD enable mode indication information is indicated. The newly introduced full duplex enable field in the RRC reconfiguration message is an optional field. If this field is not set, it indicates that the base station device does not enable the FD mode. If the full duplex enable field is set to enabled, it indicates that the base station device enables the FD mode, and the F symbol may be used for DL, UL, GP, or FD.

[0136] Here, considering that the same system information as MIB and SIB1 is transmitted by servingCellConfigCommon (serving cell common configuration), the D enable mode indication information may be indicated in the serving cell common configuration. Since the serving cell common configuration can be transmitted by an RRC reconfiguration message, the FD enable mode indication information is transmitted by introducing a full duplex enable field into the RRC reconfiguration message.

[0137] When FD enable mode indication information is added to the RRC reconfiguration message, the effective time for which FD mode is enabled may be clarified. For example, the following methods may be employed to determine the effective time for which FD mode is enabled. Method 1: FD mode is enabled in the slot following the slot in which an RRC reconfiguration complete message corresponding to the RRC reconfiguration message is received, i.e., the slot following the slot in which the RRC reconfiguration complete message is received. Method 2: FD mode is enabled in the M-th slot after the slot in which an RRC reconfiguration complete message corresponding to the RRC reconfiguration message is received, i.e., the M-th slot after the slot in which the RRC reconfiguration complete message is received. Here, M is a fixed value agreed upon between the base station apparatus and the user terminal, and M is a positive integer.

[0138] When the base station device transmits an RRC reconfiguration message to the user terminal, the user terminal may transmit an RRC reconfiguration complete message to the base station device after receiving the RRC reconfiguration message. The base station device may receive an RRC reconfiguration complete message corresponding to the RRC reconfiguration message, and use the slot in which the RRC reconfiguration complete message corresponding to the RRC reconfiguration message is transmitted as reference.

[0139] In step S33, the user terminal receives an RRC reconfiguration message from the base station apparatus.

[0140] In step S34, if FD enable mode indication information is added to the RRC reconfiguration message, the user terminal enables the FD mode for the user terminal based on the FD enable mode indication information.

[0141] When enabling FD mode for a user terminal, the effective time for which FD mode is enabled may be further clarified. For example, the following methods may be employed to determine the effective time for which FD mode is enabled for a user terminal. Method 1: The slot following the slot in which an RRC reconfiguration complete message corresponding to the RRC reconfiguration message is transmitted, i.e., the slot following the transmission slot of the RRC reconfiguration complete message. In other words, FD mode is enabled in the slot following the slot in which the RRC reconfiguration complete message corresponding to the RRC reconfiguration message is transmitted. Method 2: The M-th slot following the slot in which an RRC reconfiguration complete message corresponding to the RRC reconfiguration message is transmitted, i.e., the M-th slot following the transmission slot of the RRC reconfiguration complete message. In other words, FD mode is enabled in the M-th slot following the slot in which the RRC reconfiguration complete message corresponding to the RRC reconfiguration message is transmitted. M is a fixed value agreed upon between the base station apparatus and the user terminal, and M is a positive integer.

[0142] After receiving the RRC reconfiguration message, the user equipment may transmit an RRC reconfiguration complete message to the base station device, and therefore, the slot in which the RRC reconfiguration complete message corresponding to the RRC reconfiguration message transmitted from the user equipment is transmitted is used as reference.

[0143] In step S35, the base station device determines a target frame structure, which includes a plurality of slots, each of which includes a plurality of symbols, and the symbols may be F symbols, DL symbols, or UL symbols.

[0144] In step S36, the base station device transmits an uplink / downlink common configuration message to the user terminal, the uplink / downlink common configuration message including a frame structure parameter corresponding to the target frame structure, the frame structure parameter being used to indicate the target frame structure.

[0145] In step S37, the user terminal receives the uplink / downlink common configuration message, analyzes the frame structure parameters from the uplink / downlink common configuration message, and determines a target frame structure based on the frame structure parameters.

[0146] In step S38, the base station apparatus and the user terminal perform data processing based on the target frame structure.

[0147] Another embodiment of the present invention provides a TDD frame structure configuration method, in which the frame structure is notified to a user terminal through a slot format indication. The frame structure includes multiple slots, each including multiple symbols, which may be an F symbol, a DL symbol, or an UL symbol. When the base station device enables FD mode, the F symbol is used for FD, DL, UL, or GP. When the base station device turns off FD mode, the F symbol is used for DL, UL, or GP. Figure 6 shows an example of a frame structure. In Figure 6, slots in the frame structure include an F symbol, a DL symbol, and an UL symbol, and all F symbols are FD symbols. Of course, the F symbol may also be used for DL, UL, or GP. When the F symbol is used for GP, guarding of uplink and downlink switching can be achieved.

[0148] In this embodiment, the TDD frame structure configuration method may include the following steps:

[0149] In step S41, the base station device determines the operation mode corresponding to the base station device, which is either the FD enabled mode or the FD disabled mode.

[0150] In step S42, if the operation mode is the FD enable mode, the base station device transmits a slot format indication message (for example, carried by RRC signaling) to the user terminal. FD enable mode indication information is added to the slot format indication message. Here, adding the FD enable mode indication information to the slot format indication message may include, but is not limited to, adding the FD enable mode indication information to the slot format indication message when the slot format indication message includes a full duplex slot format combination field.

[0151] The base station device may generate at least one slot format combination (e.g., SFC). Each slot format combination includes at least one slot format. These slot formats may be selected from Table 1 or may be obtained in other ways. For example, the base station device generates slot format combination s1 and slot format combination s2. Slot format combination s1 includes slot format 0, slot format 0, slot format 2, and slot format 1, and slot format combination s2 includes slot format 0, slot format 2, slot format 1, and slot format 1.

[0152] For each slot format, the slot format may be represented by a unique slot identifier, denoted as a slot format index. For example, slot format 0 corresponds to slot format index 0, slot format 1 corresponds to slot format index 1, and slot format 2 corresponds to slot format index 2.

[0153] For each slot format combination, the slot format combination may be represented by a unique combination identifier, e.g., the combination identifier for slot format combination s1 is SFC 0, and the combination identifier for slot format combination s2 is SFC 1.

[0154] The base station apparatus may transmit a slot format indication message to the user terminal. The slot format indication message includes a combination identifier corresponding to each slot format combination and slot format indexes of all slot formats corresponding to the slot format combination. In other words, the slot format indication message includes a mapping relationship between the combination identifiers and the slot format indexes. Table 2 shows an example of the mapping relationship added to the slot format indication message.

[0155] [Table 2]

[0156] The slot format indication message is carried by RRC signaling. In one example, the slot format indication message can be carried by RRC signaling SlotFormatCombinationsPerCell.

[0157] Based on the slot format indication message described above, in this example, the slot format indication message may be extended so that FD enable mode indication information is added to the slot format indication message.

[0158] For example, a full-duplex slot format combination field is extended in the slot format indication message. The full-duplex slot format combination field is written as SlotFormatCombination-FullDuplex. If the slot format indication message includes the full-duplex slot format combination field, FD enable mode indication information is added to the slot format indication message; otherwise, FD enable mode indication information is not added to the slot format indication message.

[0159] Therefore, the base station device may transmit a slot format indication message to the user terminal, the slot format indication message including a full-duplex slot format combination field, and the full-duplex slot format combination field indicates FD enable mode indication information, and the slot format indication message includes a mapping relationship between a combination identifier corresponding to the slot format combination and the slot format indexes of all slot formats corresponding to the slot format combination.

[0160] For example, see the code below for an example of a slot format indication message. SlotFormatCombinationsPerCell ::= SEQUENCE { … slotFormatCombinations SEQUENCE (SIZE (1..maxNrofSlotFormatCombinationsPerSet)) OF SlotFormatCombination OPTIONAL, slotFormatCombinations-FullDuplex SEQUENCE (SIZE (1..maxNrofSlotFormatCombinationsPerSet)) OF SlotFormatCombination-FullDuplex OPTIONAL, ..., }

[0161] Here, SlotFormatCombination-FullDuplex represents the full-duplex slot format combination field. When SlotFormatCombination-FullDuplex is added, it represents FD enable mode indication information.

[0162] The SlotFormatCombination-FullDuplex field may contain a combination identifier corresponding to the slot format combination and a slot format index of the slot format. The SlotFormatCombination-FullDuplex field may contain up to maxNrofSlotFormatCombinationsPerSet elements, each of which is defined as follows: SlotFormatCombination-FullDuplex ::= SEQUENCE { slotFormatCombinationId - FullDuplex SlotFormatCombinationId, slotFormats-FullDuplex SEQUENCE (SIZE (1..maxNrofSlotFormatsPerCombination)) OF INTEGER (0..255) }

[0163] Here, slotFormatCombinationId-FullDuplex represents an identifier, and its value ranges from 0 to maxNrofSlotFormatCombinationsPerSet-1. That is, its value may be 0, 1, 2, ..., maxNrofSlotFormatCombinationsPerSet-1. slotFormats-FullDuplex represents a slot format index for which the slot format is unique. Up to maxNrofSlotFormatsPerCombination can be set, and its value may range from 0 to 255. If slotFormatCombinations is also set, this parameter is ignored. That is, the frame structure setting in FD mode takes precedence over the frame structure setting in HD mode. Conversely, if slotFormatCombinations-FullDuplex is not set, the frame structure depends on the setting of slotFormatCombinations, that is, it operates in HD mode in TDD.

[0164] In step S43, the user terminal receives a slot format indication message from the base station device. If the slot format indication message includes a full duplex slot format combination field, the user terminal determines that FD enable mode indication information is added to the slot format indication message.

[0165] If the slot format indication message includes a full-duplex slot format combination field, the user terminal may analyze, from the full-duplex slot format combination field, a mapping relationship between a combination identifier corresponding to the slot format combination and the slot format indexes of all slot formats corresponding to the slot format combination. For example, the user terminal may analyze, from the full-duplex slot format combination field, the mapping relationship shown in Table 2.

[0166] If the slot format indication message does not include a full-duplex slot format combination field slotFormatCombinations-FullDuplex, the user terminal may analyze the mapping relationship between the combination identifier corresponding to the slot format combination and the slot format indexes of all slot formats corresponding to the slot format combination from the slot format combination field slotFormatCombinations.

[0167] In step S44, if FD enable mode indication information is added to the slot format indication message, the user terminal enables the FD mode for this user terminal based on the FD enable mode indication information. After enabling the FD mode for the user terminal, the user terminal expects the symbol in the slot to be an F symbol, a DL symbol, or an UL symbol, and expects the F symbol in the slot to be used for FD, DL, UL, or GP.

[0168] In step S45, the base station apparatus selects a target slot format combination from all slot format combinations.

[0169] For example, the base station apparatus may select a target slot format combination from slot format combination s1 and slot format combination s2. Take the case where slot format combination s1 is selected as the target slot format combination as an example.

[0170] In step S46, the base station device may transmit a combination identifier corresponding to the target slot format combination to the user terminal by a DCI message. For example, the base station device may transmit a combination identifier corresponding to the target slot format combination to the user terminal in DCI format 2_0 via a periodic PDCCH.

[0171] In step S47, the user terminal receives a DCI message (for example, DCI format 2_0) from the base station apparatus, and analyzes the combination identifier corresponding to the target slot format combination from the DCI message.

[0172] In step S48, the user terminal selects a target slot format combination that corresponds to the combination identifier (i.e., the combination identifier parsed from the DCI message) from all slot format combinations.

[0173] For example, when the base station apparatus selects slot format combination s1 as the target slot format combination, it transmits combination identifier SFC 0 corresponding to the target slot format combination to the user terminal via a DCI message. The user terminal selects slot format combination s1 corresponding to combination identifier SFC 0 from all slot format combinations, and sets slot format combination s1 as the target slot format combination. The target slot format combination corresponds to slot format index 0, slot format index 0, slot format index 2, and slot format index 1.

[0174] The user terminal may use the SFI radio network temporary indicator to detect a DCI message such as DCI format 2_0 according to the previously configured PDCCH scanning period, and obtain a combination identifier corresponding to the target slot format combination from the SFI index field in the detected DCI message.

[0175] If SlotFormatCombination-FullDuplex (full duplex slot format combination field) is set, the SFI index of the DCI message uses SlotFormatCombination-FullDuplex, to which a combination identifier corresponding to the target slot format combination is added.

[0176] Here, the number of bits of the SFI index in the DCI message is

number

number

[0177] The settings in DCI format 2_0 can refer to the following codes: FD Slot format indicator 1, FD Slot format indicator 2, ..., FD Slot format indicator N each represent SlotFormatCombinationId-FullDuplex in SlotFormatCombination-FullDuplex. -If the higher layer parameter slotFormatCombToAddModList is configured, -if the higher layer parameter slotFormatCombinations-FullDuplex is configured - FD Slot format indicator 1, FD Slot format indicator 2, …, FD Slot format indicator N, - else -Slot format indicator 1, Slot format indicator 2, …, Slot format indicator N

[0178] In one example, when FD enable mode indication information is added to the slot format indication message, the base station device may clarify the effective time for which FD mode is enabled. For example, the following method is employed to determine the effective time for which FD mode is enabled: The FD mode is enabled in the transmission slot of the DCI message, i.e., the slot in which the DCI message is transmitted, i.e., the DCI message transmission slot. The user terminal may also clarify the effective time for which FD mode is enabled. For example, the following method is employed to determine the time for which FD mode is enabled for the user terminal: The FD mode is enabled in the reception slot of the DCI message, i.e., the slot in which the DCI message is received, i.e., the DCI message reception slot.

[0179] In step S49, the base station device determines a target frame structure based on the target slot format combination. For example, after selecting a target slot format combination from all slot format combinations, the base station device may determine the target frame structure based on all slot formats corresponding to the target slot format combination, since the target slot format combination corresponds to at least one slot format, for example, if the target slot format combination is slot format combination s1, it corresponds to slot format 0, slot format 0, slot format 2, and slot format 1.

[0180] In step S50, the user terminal determines a target frame structure based on the target slot format combination. For example, after selecting a target slot format combination from all slot format combinations, the user terminal may determine a target frame structure based on all slot formats corresponding to the target slot format combination, since the target slot format combination corresponds to at least one slot format.

[0181] In step S51, the base station apparatus and the user terminal perform data processing based on the target frame structure.

[0182] For example, when the operation mode corresponding to the base station device is an FD-enabled mode and the FD mode is enabled for the user terminal, the multiple symbols of the target frame structure may be F symbols, DL symbols, or UL symbols. When performing data processing based on the target frame structure, if the symbols in a slot are F symbols, and the F symbols in the slot are used for FD, the base station device can simultaneously process uplink data and downlink data in the time domain resource corresponding to the F symbol, and the user terminal can simultaneously process uplink data and downlink data in the time domain resource corresponding to the F symbol.

[0183] For example, assuming that the frame structure is not currently configured by TDD-UL-DL-ConfigCommon and that SFC 0 is to be adopted, the base station apparatus transmits SFC 0 to the user terminal in the DCI. Both the base station apparatus and the user terminal know the target slot format combination, and may determine the target frame structure based on the target slot format combination. Figure 7 shows an example of a target frame structure. The base station apparatus and the user terminal perform data processing based on the target frame structure shown in Figure 7, and this process is not repeated.

[0184] The above example is for a user terminal that supports FD mode. For a user terminal that does not support FD mode, the user terminal ignores the content related to FD mode, for example, ignores the FD mode indication information, and does not enable FD mode for the user terminal based on the FD enable mode indication information. The user terminal expects the symbol in the slot to be an F symbol, DL symbol, or UL symbol, and expects the F symbol in the slot to be used for DL, UL, or GP.

[0185] In one example, when the base station device activates the FD mode by an MIB message and TDD-UL-DL-ConfigCommon is set, or when the FD mode is activated by TDD-UL-DL-ConfigCommon, the F symbol in TDD-UL-DL-ConfigCommon can be further set to a DL symbol or a UL symbol, and the UL symbol or DL ​​symbol in TDD-UL-DL-ConfigCommon cannot be changed. The F symbol can be used for DL, UL, GP, or FD.

[0186] If the base station device does not activate the FD mode by a MIB message or TDD-UL-DL-ConfigCommon, regardless of whether TDD-UL-DL-ConfigCommon is currently configured, when the user terminal obtains the SlotFormatCombination-FullDuplex setting in SlotFormatCombinationsPerCell by RRC signaling and obtains the slot format based on the instruction of DCI 2_0, the user terminal determines that the current FD mode is enabled, and the effective time of the FD mode is the slot in which DCI 2_0 is received.

[0187] As can be seen from the above technical solutions, in the embodiment of the present invention, the operation modes corresponding to the base station device are divided into an FD-enabled mode and an FD-disabled mode. When the operation mode is the FD-enabled mode, the F symbol in a slot is allowed to be used for FD, that is, the function of the F symbol is extended to function as an FD symbol. In addition, when the F symbol in a slot is used for FD, uplink data and downlink data can be simultaneously processed using the time domain resource corresponding to the F symbol. In this way, uplink data and downlink data can be simultaneously processed using the same time domain resource, thereby more effectively utilizing time domain resources, improving resource utilization, improving network coverage and network capacity, and reducing uplink transmission delay, for example. The frame structure for FD mode is configured using uplink / downlink common configuration or dedicated configuration or slot format indication without affecting the current 5G system. After the frame structure configuration is completed, the base station device and the user terminal can transmit and receive data based on the type of frame structure. The base station device and the user terminal in FD mode can transmit and receive simultaneously, while the user terminal in HD mode can only transmit or receive at the same time. The functionality of the F symbol has been extended to function as an FD symbol, allowing for more flexible configuration of the FD symbol.

[0188] Based on the same inventive idea, a TDD frame structure setting device, a base station device, and a user terminal corresponding to the above TDD frame structure setting method are further provided. Since the principles by which the base station device and the user terminal solve the problem are similar to those of the TDD frame structure setting method of the above embodiment, the implementation of the base station device and the user terminal can refer to the implementation of the method, and will not be repeated in this specification.

[0189] Based on the same idea as the above method, one embodiment of the present invention provides a TDD frame structure setting device applied to a base station device, the device comprising: a determination module for determining an operation mode corresponding to a base station device, the operation mode being an FD enable mode or an FD disable mode, and when the operation mode is the FD enable mode, an F symbol in a slot is permitted to be used for FD, DL, UL, or GP, and when the operation mode is the FD disable mode, an F symbol in a slot is permitted to be used for DL, UL, or GP; a transmitting module, when the operation mode is an FD enable mode, for transmitting FD enable mode indication information to a user terminal, thereby causing the user terminal to enable an FD mode for the user terminal according to the FD enable mode indication information; When the operation mode is an FD enabled mode, the device includes a processing module for simultaneously processing uplink data and downlink data in a time domain resource corresponding to an F symbol when the F symbol in the slot is used for FD.

[0190] In one example, when the transmitting module transmits FD enable mode indication information to a user terminal, the transmitting module is specifically used to transmit a system broadcast message to which the FD enable mode indication information is added to the user terminal, or to transmit an RRC reconfiguration message to which the FD enable mode indication information is added to the user terminal.
