Technical Field

[0002] Full-duplex and half-duplex transmissions are two typical data transmission methods. Among them, full-duplex transmission can perform two-way signal transmission simultaneously.

In wireless communication technologies, available frequency resources can be divided into several subbands, and the channel quality on each subband can be measured separately. The frequency resources in the subband with the smallest signal transmission fading can be selected and allocated to users, thereby implementing frequency-selective scheduling, also known as subband scheduling.

[0073] For the convenience of those skilled in the art to understand, the embodiments of the present disclosure list multiple implementation manners to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the multiple embodiments provided by the embodiments of the present disclosure can be executed alone, or can be executed together after being combined with the methods of other embodiments in the embodiments of the present disclosure, or can be executed alone or in combination with some methods in other related technologies; the embodiments of the present disclosure do not make any limitations in this regard.

[0074] To better understand the technical solutions described in any embodiment of the present disclosure, first, the application scenarios in the related technologies are described:

[0075] In one embodiment, the enhancement for the full-duplex transmission mode is only targeted at the base station side, while the terminal side still only supports the half-duplex transmission mode. The reason is that if transmission and reception are to be achieved simultaneously on a single carrier, the transmitter and receiver need to be able to effectively suppress cross-slot interference and self-interference. For cross-slot interference, certain mechanisms can be used for measurement, avoidance, and elimination. For self-interference, the device requires a high transmit-receive isolation degree to achieve a strong self-interference suppression ability. Generally speaking, the full-duplex transmission mode can bring about an increase in throughput, a reduction in transmission delay (especially for uplink transmission), and an enhancement of the uplink coverage range. To achieve the foregoing objectives, it is necessary to schedule uplink transmission in the downlink region of the time-division duplexing (TDD) frequency band or on the downlink spectrum of the frequency-division duplexing (FDD) frequency band. According to the relevant protocol, the terminal will not send uplink data within the downlink time slot. Therefore, the base station needs to indicate to the terminal the frequency-domain range available for uplink transmission within the downlink time slot. However, there is currently no clear method to indicate the resources for uplink data transmission in the downlink time slot.

[0076] In one embodiment, it can be to simultaneously receive and send data within a single time slot. To minimize the impact on terminal complexity and radio frequency aspects, the research on enhancing the duplex mode can be restricted to the base station side, that is, only the base station side supports full duplex.

[0077] Exemplarily, Figure 2 shows the co-channel interference between base stations; Figure 3 shows the co-channel interference between terminals.

[0078] In some embodiments, for the full-duplex solution on the base station side, there are mainly the following three types:

[0079] Non-overlapping subbands, that is, uplink and downlink data are transmitted on different subbands, and there is no overlap in the frequency domain between the subbands;

[0080] Partially overlapping subbands, that is, uplink and downlink data are transmitted on different subbands, and there is partial overlap in the frequency domain between the subbands;

[0081] Co-spectrum full duplex, that is, uplink and downlink data can be transmitted on completely overlapping frequency-domain resources.

[0082] In one embodiment, a terminal or a base station obtains frame structure information through higher layer signaling or physical layer signaling, and the frame structure information indicates transmission direction information of a target transmission unit. The transmission direction indication information may be "D" (indicating that the transmission direction of the target transmission unit is the downlink transmission direction), "U" (indicating that the transmission direction of the target transmission unit is the uplink transmission direction), and "F" (indicating that the transmission direction of the target transmission unit is neither uplink nor downlink; or indicating that the transmission direction of the target transmission unit may be either uplink or downlink).

[0083] The transmission direction information between different transmission units may change dynamically. Therefore, it is necessary to clarify how to determine the transmission direction on the target transmission unit.

[0084] As Figure 4 shown, in this embodiment, a method for determining the transmission direction is provided. Among them, this method is executed by an access network device, and this method includes:

[0085] Step 41: Send configuration information of at least one subband to the terminal;

[0086] Among them, the configuration information is used for the terminal to determine: the transmission direction of the subband to transmit data on the target transmission unit configured in the first state.

[0087] Here, the terminal involved in the present disclosure may be, but is not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a roadside unit (RSU), a smart home terminal, an industrial sensing device, and / or a medical device, etc. In some embodiments, the terminal may be a Redcap terminal or a new radio (NR) terminal of a predetermined version (for example, an NR terminal of R17).

[0088] The access network device involved in the present disclosure may be various types of base stations, for example, a base station in a third-generation mobile communication (3G) network, a base station in a fourth-generation mobile communication (4G) network, a base station in a fifth-generation mobile communication (5G) network, or other evolved base stations.

[0089] It should be noted that frequency resources can be divided into multiple subbands. The same target transmission unit may correspond to multiple subbands in the frequency domain. Transmissions in different transmission directions can be performed on each subband.

[0090] For example, if the target transmission unit includes a first subband, a second subband, and a third subband in the frequency domain, then uplink transmission can be performed on the first subband, downlink transmission can be performed on the second subband, and the transmission direction on the third subband is uncertain.

[0091] Among them, the target transmission unit may be a transmission unit in the time domain. The target transmission unit includes one or more of the following: symbol, time slot, subframe, and radio frame. However, the target transmission unit is not limited to the above examples.

[0092] In one embodiment, configuration information of at least one subband is sent to a terminal. The configuration information is used for the terminal to determine the transmission direction of data transmitted by the subband on a target transmission unit configured in a first state, where the first state is a state with an unclear transmission direction. It should be noted that the access network device may pre-configure the first state of the subband.

[0093] In one embodiment, an access network device sends configuration information of at least one subband to a terminal. The configuration information is used for the terminal to determine the transmission direction of data transmitted by the subband on a target transmission unit configured in a first state. After receiving the configuration information sent by the access network device, the terminal determines the transmission direction of data transmitted by the subband on the target transmission unit according to the configuration information, and the terminal performs data transmission based on this transmission direction. It can be understood that the first state is a state with an unclear transmission direction, and this configuration information essentially clarifies the transmission direction, so that the transmission direction of data transmitted by the subband on the target transmission unit changes from an unclear state to a clear state.

[0094] In one embodiment, first configuration information of at least one subband is sent to a terminal. The first configuration information is used to indicate that the transmission direction of data transmitted by a target subband on a target transmission unit configured in a first state is a downlink transmission direction. After receiving the first configuration information sent by the access network device, the terminal determines the transmission direction of data transmitted by the target subband on the target transmission unit configured in a first state according to the first configuration information, and transmits downlink data on the target subband.

[0095] In one embodiment, second configuration information of at least one subband is sent to a terminal. The second configuration information is used to indicate that the transmission direction of data transmitted by a target subband on a target transmission unit configured in a first state is an uplink transmission direction. After receiving the second configuration information sent by the access network device, the terminal determines the transmission direction of data transmitted by the target subband on the target transmission unit configured in a first state according to the first configuration information, and transmits uplink data on the target subband.

[0096] In one embodiment, configuration information of at least one subband is sent to a terminal through physical layer signaling. The configuration information is used for the terminal to determine the transmission direction of data transmitted by the subband on a target transmission unit configured in a first state.

[0097] In one embodiment, the configuration information is sent to the terminal through high-layer signaling.

[0098] In one embodiment, configuration information of at least one sub-band is sent to a terminal through common downlink control information (DCI); wherein, the configuration information is used for the terminal to determine the transmission direction of data transmitted by the sub-band on a target transmission unit configured in a first state.

[0099] In one embodiment, configuration information of at least one sub-band is sent to a terminal through terminal-specific DCI; wherein, the configuration information is used for the terminal to determine the transmission direction of data transmitted by the sub-band on a target transmission unit configured in a first state.

[0100] In one embodiment, please refer to Figure 5 , in a target transmission unit (e.g., a time slot) in the frequency domain, the frequency domain resources are divided into 5 sub-bands. If the target transmission unit is a time slot, the sub-bands on the first time slot and the fourth time slot are configured for uplink transmission, the sub-bands on the third time slot and the sixth time slot are configured for downlink transmission, the sub-bands on the second time slot and the fifth time slot can be configured for uplink transmission or downlink transmission, or it is not determined which direction the transmission is in, that is, the transmission direction is not clear.

[0101] It should be noted that the sub-bands can be pre-configured by pre-configuration information. The pre-configuration information can carry different indicators. Exemplarily, when the sub-band of the first time slot is configured for uplink transmission, the corresponding indicator is "U"; when the terminal receives the pre-configuration information carrying the indicator "U", it determines that the transmission direction on the first time slot is only uplink transmission (the corresponding sub-band is an uplink transmission sub-band). When the sub-band of the second time slot is configured for transmission with an unclear direction, the corresponding indicator is "F"; when the terminal receives the pre-configuration information carrying the indicator "F", it determines that the transmission direction on the second time slot can be flexibly transmitted, and can be either uplink transmission or downlink transmission. It should be noted that some sub-bands can only be for uplink transmission and some sub-bands can only be for downlink transmission. When the sub-band of the third time slot is configured for downlink transmission, the corresponding indicator is "D", and when the terminal receives the pre-configuration information carrying the indicator "F", it determines that the transmission direction on the third time slot is only downlink transmission (the corresponding sub-band is a downlink transmission sub-band). Here, the sub-bands configured by the pre-configuration information are in the first state.

[0102] It should be noted that the identifiers "U", "F", and "D" are only examples, and new definitions can be made according to the specific scenarios of the transmission direction, and are not limited to the above identifiers and / or the above 3 identifiers. In another description, the identifier can also be understood as status indication information. The identifier can be indicated by 1 or 2 bits.

[0103] In one embodiment, the configuration information may be configured in units of all sub - bands on a target transmission unit. Exemplarily, if the configuration information carries "UDUDF", it indicates that: all sub - bands on the first time slot and the third time slot are for uplink transmission, all sub - bands on the second time slot and the fourth time slot are for downlink transmission, and the sub - bands on the fifth time slot are for transmission in an undetermined direction.

[0104] In one embodiment, the configuration information may also be configured in units of each sub - band on a target transmission unit. Exemplarily, if the configuration information carries "UDU", "FDU", and "UUD", it indicates that: the first and third sub - bands on the first time slot are for uplink transmission, and the second sub - band is for downlink transmission; the first sub - band on the second time slot is for transmission in an undetermined direction, the second sub - band is for downlink transmission, and the third sub - band is for uplink transmission; the first and second sub - bands on the third time slot are for uplink transmission, and the third sub - band is for downlink transmission.

[0105] In one embodiment, before the access network device sends the configuration information of at least one sub - band to the terminal, it pre - sends mapping relationship information, where the mapping relationship information indicates the mapping relationship between the identifier and the sub - band configuration. Thus, after receiving the configuration information, the terminal can determine the sub - band configuration based on the identifier indicated by the configuration information and the mapping relationship information, and the terminal can determine the transmission direction of the sub - band for transmitting data on the target transmission unit configured in the first state according to the sub - band configuration.

[0106] In one embodiment, please refer to Table 1, which shows the mapping relationship between the identifier (which can also be called the configuration number) and the sub - band configuration.

[0107] Identifier Subband Configuration 00 Subband Configuration 1 01 Subband Configuration 1, Subband Configuration 2 10 Subband Configuration 2, Subband Configuration 3 11 Subband Configuration 2, Subband Configuration 3, Subband Configuration 4

[0108] Exemplarily, the sub - band configuration 1 may be "UDUDU", that is, when the identifier indicated by the configuration information is "00", the transmission directions of the 5 sub - bands on a certain time slot for transmitting data on the target transmission unit configured in the first state are uplink transmission, downlink transmission, uplink transmission, downlink transmission, and uplink transmission. For the case of having multiple sub - band configurations, different sub - band configurations may be applied to the sub - bands on different target transmission units. For example, when the identifier indicated by the configuration information is "01", the sub - band configuration 1 is applied to the first time slot, and the sub - band configuration 2 is applied to the third time slot.

[0109] In an embodiment of the present disclosure, configuration information of a sub-band is sent to a terminal; wherein, the configuration information is used for the terminal to determine: the transmission direction of the sub-band for transmitting data on a target transmission unit configured in a first state. Here, since the configuration information indicates the transmission direction of the sub-band for transmitting data on the target transmission unit configured in the first state, after receiving the configuration information, the terminal can determine or adjust the transmission direction of the sub-band for transmitting data on the target transmission unit configured in the first state. In this way, the transmission direction can be dynamically configured, and compared with the situation where the transmission direction cannot be determined or is unclear, the reliability of data transmission can be improved.

[0110] It should be noted that those skilled in the art can understand that the method provided in the embodiment of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0111] In one embodiment, the transmission direction includes one of the following: an uplink transmission direction or a downlink transmission direction.

[0112] In one embodiment, the target transmission unit includes one or more of the following: a symbol, a time slot, a sub-frame, and a radio frame.

[0113] As Figure 6 shown, in this embodiment, a method for determining a transmission direction is provided, wherein the method is executed by an access network device, and the method includes:

[0114] Step 61, determine a target transmission unit according to a first rule.

[0115] In one embodiment, the first rule indicates the target transmission unit of the sub-band that needs to be configured by the configuration information.

[0116] In one embodiment, determine the transmission unit on which the sub-band is pre-configured with an unclear transmission direction as the target transmission unit.

[0117] In one embodiment, the target transmission unit can be determined according to the configuration of the pre-configuration information.

[0118] It should be noted that those skilled in the art can understand that the method provided in the embodiment of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0119] As Figure 7 shown, in this embodiment, a method for determining a transmission direction is provided, wherein the method is executed by an access network device, and the method includes:

[0120] Step 71: Send the configuration information to the terminal through a physical layer signaling, where the physical layer signaling includes one of the following: common downlink control information (DCI) or terminal-specific DCI.

[0121] In one embodiment, send the configuration information of at least one sub-band to the terminal through common downlink control information (DCI); where the configuration information is used for the terminal to determine: the transmission direction of the sub-band for transmitting data on the target transmission unit configured in the first state. After receiving the configuration information sent by the access network device, the terminal determines the transmission direction of the sub-band for transmitting data on the target transmission unit according to the configuration information; the terminal performs data transmission based on this transmission direction. It can be understood that the first state is a state where the transmission direction is not clear, and this configuration information substantially clarifies the transmission direction, making the transmission direction of the sub-band for transmitting data on the target transmission unit change from an unclear state to a clear state.

[0122] In one embodiment, send the configuration information of at least one sub-band to the terminal through terminal-specific DCI; where the configuration information is used for the terminal to determine: the transmission direction of the sub-band for transmitting data on the target transmission unit configured in the first state. After receiving the configuration information sent by the access network device, the terminal determines the transmission direction of the sub-band for transmitting data on the target transmission unit according to the configuration information; the terminal performs data transmission based on this transmission direction. It can be understood that the first state is a state where the transmission direction is not clear, and this configuration information substantially clarifies the transmission direction, making the transmission direction of the sub-band for transmitting data on the target transmission unit change from an unclear state to a clear state.

[0123] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0124] In one embodiment, the configuration information indicates the configuration information of one or more sub-bands.

[0125] In one embodiment, the configuration information indicates the configuration information of the sub-bands on multiple consecutive target transmission units.

[0126] In one embodiment, the access network device pre-sends the information of the mapping relationship to the terminal. It can be that the access network device pre-sends the information of the mapping relationship to the terminal through a high-layer signaling. The information of the mapping relationship indicates the transmission configuration of the identifier and the sub-bands on one or more target transmission units.

[0127] It should be noted that when the information of the mapping relationship indicates the relationship between an identifier and a sub-band configuration, the sub-band configuration is the sub-band configuration of the sub-bands on a single target transmission unit. When the information of the mapping relationship indicates the relationship between an identifier and multiple sub-band configurations, the multiple sub-band configurations are the sub-band configurations on multiple target transmission units. The multiple target transmission units may be multiple consecutive target transmission units.

[0128] Please refer to Table 1 again and Figure 5 , when the configuration information indicates the identifier "00", according to the identifier and the information of the mapping relationship, it is determined that the sub-band configuration is sub-band configuration 1 (for example, UDUDU). Then, the terminal can determine that the sub-band configuration information indicated on the target transmission unit configured in the first state is the sub-band configuration on one target transmission unit. For example, it is Figure 5 the sub-band configuration in the second time slot in Figure 5 . When the identifier indicated by the configuration information is "01", then the terminal can determine that the sub-band configuration information indicated on the target transmission unit configured in the first state is the sub-band configuration on 2 target transmission units. For example, it is

[0129] The information field of the configuration information is determined according to the number of configuration information, the number of sub-bands, and / or the indication field of the configuration information indicating the first state. Here, the first state may be a state where the transmission direction of the sub-band is uncertain.

[0130] As Figure 8 shown, in this embodiment, a method for determining the transmission direction is provided. Among them, this method is executed by the access network device, and the configuration information indicates the identifier; before sending the configuration information of at least one sub-band to the terminal, this method includes:

[0131] Step 81, pre-send mapping relationship information, where the mapping relationship information indicates the mapping relationship between the identifier and the sub-band configuration; among them, the sub-band configuration indicates the transmission direction of the sub-band for transmitting data on the target transmission unit configured in the first state.

[0132] In one embodiment, the access network device pre-sends the mapping relationship information before sending the configuration information of at least one sub-band to the terminal, where the mapping relationship information indicates the mapping relationship between the identifier and the sub-band configuration. In this way, after receiving the configuration information, the terminal can determine the sub-band configuration based on the identifier indicated by the configuration information and the mapping relationship information. The terminal can determine the transmission direction of the sub-band for transmitting data on the target transmission unit configured in the first state according to this sub-band configuration.

[0133] For the description in Step 81, please specifically refer to the description in Step 41, and details are not described here again.

[0134] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0135] As Figure 9 shown, a method for determining a transmission direction is provided in this embodiment. Among them, this method is executed by a terminal, and this method includes:

[0136] Step 91, receiving configuration information of at least one sub-band sent by an access network device;

[0137] Step 92, determining the transmission direction of the sub-band for transmitting data on a target transmission unit configured in a first state according to the configuration information.

[0138] Here, the terminal involved in the present disclosure may be, but is not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a roadside unit (RSU, Road Side Unit), a smart home terminal, an industrial sensing device, and / or a medical device, etc. In some embodiments, the terminal may be a Redcap terminal or a new radio (NR) terminal of a predetermined version (for example, an NR terminal of R17).

[0139] The access network device involved in the present disclosure may be various types of base stations. For example, a base station of a third-generation mobile communication (3G) network, a base station of a fourth-generation mobile communication (4G) network, a base station of a fifth-generation mobile communication (5G) network, or other evolved base stations.

[0140] It should be noted that frequency resources can be divided into multiple sub-bands. Multiple sub-bands can correspond in the frequency domain on the same target transmission unit. Transmissions in different transmission directions can be performed on each sub-band.

[0141] For example, if the target transmission unit includes a first sub-band, a second sub-band, and a third sub-band in the frequency domain, then uplink transmission can be performed on the first sub-band, downlink transmission can be performed on the second sub-band, and the transmission direction on the third sub-band is uncertain.

[0142] Among them, the target transmission unit may be a transmission unit in the time domain. The target transmission unit includes one or more of the following: symbols, time slots, sub-frames, and radio frames, but the target transmission unit is not limited to the above examples.

[0143] In one embodiment, receive configuration information of at least one sub-band sent by an access network device; among them, the configuration information is used for the terminal to determine: the transmission direction of the sub-band for transmitting data on a target transmission unit configured in a first state; where the first state is a state where the transmission direction is not clear. It should be noted that the first state of the sub-band may be pre-configured by the access network device.

[0144] In one embodiment, the access network device sends configuration information of at least one sub-band to the terminal; wherein, the configuration information is used for the terminal to determine: the transmission direction of data transmission on the target transmission unit configured in the first state. After receiving the configuration information sent by the access network device, the terminal determines, according to the configuration information, the transmission direction of data transmission on the target transmission unit; and the terminal performs data transmission based on this transmission direction. It can be understood that the first state is a state where the transmission direction is not clear, and this configuration information essentially clarifies the transmission direction, so that the transmission direction of data transmission on the target transmission unit by the sub-band changes from an unclear state to a clear state.

[0145] In one embodiment, the terminal receives the first configuration information of at least one sub-band sent by the access network device, wherein the first configuration information is used to indicate that the transmission direction of the data transmitted by the target sub-band on the target transmission unit configured in the first state is the downlink transmission direction. After receiving the first configuration information sent by the access network device, the terminal determines, according to the first configuration information, the transmission direction of the data transmitted by the target sub-band on the target transmission unit configured in the first state, and transmits downlink data on the target sub-band.

[0146] In one embodiment, the terminal receives the second configuration information of at least one sub-band sent by the access network device, wherein the second configuration information is used to indicate that the transmission direction of the data transmitted by the target sub-band on the target transmission unit configured in the first state is the uplink transmission direction. After receiving the second configuration information sent by the access network device, the terminal determines, according to the first configuration information, the transmission direction of the data transmitted by the target sub-band on the target transmission unit configured in the first state, and transmits uplink data on the target sub-band.

[0147] In one embodiment, the terminal receives the configuration information of at least one sub-band sent by the access network device through physical layer signaling; wherein the configuration information is used for the terminal to determine: the transmission direction of data transmission on the target transmission unit configured in the first state.

[0148] In one embodiment, the configuration information is sent to the terminal through high-layer signaling.

[0149] In one embodiment, the terminal receives the configuration information of at least one sub-band sent by the access network device through common downlink control information (DCI); wherein the configuration information is used for the terminal to determine: the transmission direction of data transmission on the target transmission unit configured in the first state.

[0150] In one embodiment, configuration information of at least one sub-band sent by an access network device is received through terminal-specific DCI; wherein, the configuration information is used for the terminal to determine the transmission direction of the sub-band for transmitting data on a target transmission unit configured in a first state.

[0151] In one embodiment, refer to Figure 5 , the frequency domain resources are divided into 5 sub-bands on a target transmission unit (for example, a time slot). If the target transmission unit is a time slot, the sub-bands on the first time slot and the fourth time slot are configured for uplink transmission, the sub-bands on the third time slot and the sixth time slot are configured for downlink transmission, and the sub-bands on the second time slot and the fifth time slot can be configured for uplink transmission or downlink transmission, or the transmission direction is not determined, that is, the transmission direction is not clear.

[0152] It should be noted that the sub-bands can be pre-configured by pre-configuration information. The pre-configuration information can carry different indicators. Exemplarily, when the sub-band of the first time slot is configured for uplink transmission, the corresponding indicator is "U"; when the terminal receives the pre-configuration information carrying the indicator "U", it is determined that the transmission direction on the first time slot is only uplink transmission (the corresponding sub-band is an uplink transmission sub-band). When the sub-band of the second time slot is configured for an unclear direction of transmission, the corresponding indicator is "F"; when the terminal receives the pre-configuration information carrying the indicator "F", it is determined that the transmission direction on the second time slot can be flexibly transmitted, and it can be uplink transmission or configured for downlink transmission. It should be noted that some sub-bands can only be for uplink transmission and some sub-bands can only be for downlink transmission. When the sub-band of the third time slot is configured for downlink transmission, the corresponding indicator is "D", and when the terminal receives the pre-configuration information carrying the indicator "F", it is determined that the transmission direction on the third time slot is only downlink transmission (the corresponding sub-band is a downlink transmission sub-band). Here, the sub-bands configured by the pre-configuration information are in the first state.

[0153] It should be noted that the identifiers "U", "F", and "D" are only examples, and new definitions can be made according to the specific scenarios of the transmission direction, and are not limited to the above identifiers and / or the above 3 identifiers. In another description, the identifier can also be understood as status indication information. The identifier can be indicated by 1 or 2 bits.

[0154] In one embodiment, the configuration information can be configured in units of all sub-bands on the target transmission unit. Exemplarily, if the configuration information carries "UDUDF", it indicates that all sub-bands on the first time slot and the third time slot are for uplink transmission, all sub-bands on the second time slot and the fourth time slot are for downlink transmission, and the sub-bands on the fifth time slot are for an undetermined direction of transmission.

[0155] In one embodiment, the configuration information may also be configured for each sub - band on the target transmission unit. Exemplarily, if the configuration information carries "UDU", "FDU", and "UUD", it indicates that: the first and third sub - bands on the first time slot are for uplink transmission, the second sub - band is for downlink transmission; the first sub - band on the second time slot is for transmission in an uncertain direction, the second sub - band is for downlink transmission, and the third sub - band is for uplink transmission; the first and second sub - bands on the third time slot are for uplink transmission, and the third sub - band is for downlink transmission.

[0156] In one embodiment, the access network device pre - sends mapping relationship information before sending the configuration information of at least one sub - band to the terminal, where the mapping relationship information indicates the mapping relationship between the identifier and the sub - band configuration. In this way, after receiving the configuration information, the terminal can determine the sub - band configuration based on the identifier indicated by the configuration information and the mapping relationship information, and the terminal can determine the transmission direction of the sub - band for transmitting data on the target transmission unit configured in the first state according to the sub - band configuration.

[0157] In one embodiment, referring to Table 1 again, it shows the mapping relationship between the identifier (which can also be called the configuration number) and the sub - band configuration.

[0158] Exemplarily, the sub - band configuration 1 can be "UDUDU", that is, when the identifier indicated by the configuration information is "00", the transmission directions of the 5 sub - bands on a certain time slot for transmitting data on the target transmission unit configured in the first state are uplink transmission, downlink transmission, uplink transmission, downlink transmission, and uplink transmission. For the case of having multiple sub - band configurations, different sub - band configurations can be applied to the sub - bands on different target transmission units. For example, when the identifier indicated by the configuration information is "01", the sub - band configuration 1 is applied to the first time slot, and the sub - band configuration 2 is applied to the third time slot.

[0168] In one embodiment, receive configuration information of at least one sub-band sent by an access network through common downlink control information (DCI, Downlink Control Information); where the configuration information is used for the terminal to determine: the transmission direction of data transmission on a target transmission unit configured in a first state. After receiving the configuration information sent by the access network device, the terminal determines the transmission direction of data transmission on the target transmission unit according to the configuration information; the terminal performs data transmission based on this transmission direction. It can be understood that the first state is a state where the transmission direction is unclear, and this configuration information substantially clarifies the transmission direction, so that the transmission direction of data transmission on the target transmission unit changes from an unclear state to a clear state.

[0172] In one embodiment, the configuration information indicates the configuration information of sub-bands on a plurality of consecutive target transmission units.

[0173] In one embodiment, the access network device pre-sends information on the mapping relationship to the terminal. It can be that the access network device pre-sends information on the mapping relationship to the terminal through high-layer signaling. The information on the mapping relationship indicates the transmission configuration of the identifier and the sub-bands on one or more target transmission units.

[0174] It should be noted that when the information on the mapping relationship indicates the relationship between an identifier and a sub-band configuration, the sub-band configuration is the sub-band configuration of the sub-band on a single target transmission unit. When the information on the mapping relationship indicates the relationship between an identifier and a plurality of sub-band configurations, the plurality of sub-band configurations are the sub-band configurations on a plurality of target transmission units. The plurality of target transmission units can be a plurality of consecutive target transmission units.

[0175] Please refer to Table 1 again and Figure 5 , when the configuration information indicates the identifier "00", according to the identifier and the information on the mapping relationship, it is determined that the sub-band configuration is sub-band configuration 1 (for example, UDUDU). Then the terminal can determine that the sub-band configuration information indicated on the target transmission unit configured in the first state is the sub-band configuration on one target transmission unit. For example, it is Figure 5 the sub-band configuration in the second time slot in Figure 5 . When the identifier indicated by the configuration information is "01", then the terminal can determine that the sub-band configuration information indicated on the target transmission unit configured in the first state is the sub-band configuration on 2 target transmission units. For example, it is
