[0090] FIG. 1 is a schematic diagram of an architecture of a communication system according to an embodiment of the present disclosure.

[0091] As shown in FIG. 1, the communication system 100 includes a terminal 101 and a network device 102.

[0092] In some embodiments, the terminal 101 includes at least one of a mobile phone, a wearable device, an Internet of Things device, a communication-capable automobile, a smart automobile, a Pad, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in smart grid, a wireless terminal device in transportation safety, a wireless terminal device in smart city, a wireless terminal device in smart home, etc., but is not limited thereto.

[0093] In some embodiments, the network device 102 includes at least one of an access network device, a core network device, etc., but is not limited thereto.

[0094] In some embodiments, the access network device is, for example, a node or device that accesses a terminal to a wireless network, and the access network device can include at least one of an evolved NodeB (eNB) in a 5G communication system, a next generation eNB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved node B (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, an access node in a Wi-Fi system, but is not limited thereto.

[0095] In some embodiments, the technical solutions of the present disclosure can be applied to an Open RAN architecture, at this time, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can become internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be realized through software or programs.

[0096] In some embodiments, the access network device can be composed of a central unit (CU) and a distributed unit (DU), wherein the CU can also be referred to as a control unit (control unit). The CU-DU structure can split the protocol layers of the access network device, and part of the functions of the protocol layers are controlled by the CU, and the remaining part or all of the functions of the protocol layers are distributed in the DU and controlled by the CU, but the present disclosure is not limited thereto.

[0097] In some embodiments, the core network device can be one device including multiple network elements, etc., or can be multiple devices or device groups, each including all or part of multiple network elements. The network element can be virtual or physical. The core network includes, for example, at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next generation core (NGC).

[0098] In embodiments of the present disclosure, as one possible solution, the network device can schedule or instruct a full-duplex terminal to transmit or receive data on semi-static flexible symbols. However, for semi-static flexible symbols, the network device can further indicate the transmission direction as uplink (UL), downlink (DL) or dynamic flexible through UE-dedicated RRC signaling. When the transmission direction indicated by the UE-dedicated RRC signaling conflicts with the data / signal transmission direction indicated by the network device, the terminal behavior needs to be clarified.

[0099] In some embodiments, the network device can configure the cell-level time division duplex uplink-downlink configuration (TDD UL-DL configuration) through the time division duplex uplink-downlink common configuration (tdd-UL-DL-ConfigurationCommon) carried in the system information block 1 (SIB1). Additionally, if the network device configures the time division duplex uplink-downlink dedicated configuration (tdd-UL-DL-ConfigurationDedicated) carried in the RRC signaling, the TDD UL-DL configuration should be determined by both.

[0100] In some embodiments, the TDD UL-DL configuration can include the following three types of time domain resources:

[0101] Semi-static downlink symbols (DL symbols);

[0102] Semi-static uplink symbols (UL symbols);

[0103] Semi-static flexible symbols.

[0104] Among them, the transmission direction of the semi-static DL symbol and the semi-static UL symbol cannot be changed, while the semi-static flexible symbol configured through cell-specific signaling can further adjust the transmission direction through UE-dedicated RRC signaling, for example, indicating the semi-static flexible symbol as UL, DL or flexible.

[0105] In the related art, the network device can simultaneously schedule different terminals for uplink and downlink transmission on the semi-static flexible symbol. Specifically, the following different ways can be used to achieve this:

[0106] Method 1: Explicit signaling is used to configure the uplink subband (UL subband) or downlink subband (DL subband) on the semi-static flexible symbol. The UL subband and DL subband are respectively used for uplink transmission and downlink transmission.

[0107] Method 2: The duplex terminal is instructed to transmit or receive on the semi-static flexible symbol by scheduling, that is, the full duplex operation is transparent to the duplex terminal at this time.

[0108] For the semi-static flexible symbol, the network device can further change the transmission direction by UE-dedicated RRC signaling, for example, indicating the symbol as DL, UL or dynamic flexible. At this time, the transmission direction indicated by the RRC signaling may be different from the transmission direction indicated or configured by the base station for the duplex terminal.

[0109] For example, when the duplex terminal transmits uplink data in the UL subband on the semi-static flexible symbol, the network device, such as a base station, indicates the symbol as DL by UE-dedicated RRC signaling. At this time, the corresponding behavior of the duplex terminal needs to be clarified.

[0110] For another example, when the duplex terminal transmits downlink data in the DL subband on the semi-static flexible symbol, the base station indicates the symbol as UL by UE-dedicated RRC signaling. At this time, the corresponding behavior of the duplex terminal needs to be clarified.

[0111] In order to clarify the terminal behavior when the above conflict occurs, the present disclosure provides the following communication method and terminal, network device, system and storage medium.

[0112] FIG. 2 is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiment of the present disclosure relates to a communication method, and the above method comprises:

[0113] Step SS2101: The network device 102 sends a first configuration to the terminal 101.

[0114] In some embodiments, the terminal 101 in the present disclosure can be a terminal supporting full duplex operation.

[0115] In some embodiments, the semi-static flexible time unit can be configured by the network device 102 through tdd-UL-DL-ConfigurationCommon.

[0116] In one example, the time unit in the present disclosure can be in units of symbol, slot, sub-slot, frame, subframe, etc., which is not limited in the present disclosure.

[0117] In one example, one sub-slot includes n symbols belonging to the same slot, where n can be a positive integer.

[0118] In some embodiments, the terminal 101 can send uplink information on the uplink sub-band on the semi-static flexible symbol, or can receive downlink information on the downlink sub-band on the semi-static flexible symbol.

[0119] In some embodiments, based on the above premise, the first configuration can be used to configure the sub-band on one or more time units, and the transmission direction of the sub-band can be the first direction.

[0120] In one example, the network device 102 can configure a semi-static flexible time unit through tdd-UL-DL-ConfigurationCommon, and configure a sub-band on the semi-static flexible time unit through explicit signaling, and the transmission direction of the sub-band can be uplink or downlink.

[0121] In some embodiments, the terminal 101 receives the first configuration.

[0122] Step S2102, the network device 102 sends the second configuration to the terminal 101.

[0123] In some embodiments, the second configuration can be used to configure the transmission direction of the above-mentioned time unit, such as the semi-static flexible time unit, to the second direction.

[0124] In one example, the second configuration can be configured through UE-dedicated RRC signaling.

[0125] In one example, the second configuration can be configured through tdd-UL-DL-ConfigurationDedicated carried by RRC signaling.

[0126] In some embodiments, the transmission direction of the time unit is configured as a second direction, the second direction being different from the first direction, for example, the first direction is uplink, and the second direction is flexible or downlink, or the first direction is downlink, and the second direction is uplink or flexible.

[0127] In some embodiments, the terminal 101 receives the second configuration.

[0135] The way in which the network device 102 determines its own behavior will be described in subsequent embodiments, which will not be described here.

[0136] It can be understood that the behavior of the terminal 101 on the time unit and the behavior of the network device 102 on the time unit should be matched, for example, the terminal 101 transmits or receives information on the time unit according to the first configuration, and the network device 102 should also receive or transmit information on the time unit according to the first configuration. For another example, the terminal 101 transmits or receives information on the time unit according to the second configuration, and the network device 102 should also receive or transmit information on the time unit according to the second configuration, thereby improving the reliability of SBFD communication.

[0141] In some embodiments, the information transmission method according to the embodiments of the present disclosure can include at least one of steps S2101-S2104. For example, step S2101 can be implemented as an independent embodiment, step S2102 can be implemented as an independent embodiment, steps S2101+S2102 can be implemented as an independent embodiment, step S2103 can be implemented as an independent embodiment, step S2104 can be implemented as an independent embodiment, steps S2103+S2104 can be implemented as an independent embodiment, step S2104 can be implemented as an independent embodiment, steps S2101-S2104 can be implemented as an independent embodiment, but the present disclosure is not limited thereto.

[0145] In some embodiments, steps S2101-S2104 are optional, and one or more of the steps can be omitted or replaced in different embodiments.

[0146] In some embodiments, the order of execution of steps S2101-S2104 is not limited.

[0147] In the above embodiments, when the transmission direction of the subband configured by the first configuration conflicts with the transmission direction of the time unit configured by the second configuration, the terminal behavior is clarified, the reliability of SBFD communication is improved, and the availability is high.

[0148] In some embodiments, the first configuration in the embodiments of the present disclosure is used to configure a subband on the time unit, and the transmission direction of the subband is the first direction. The first direction can be uplink or downlink, and accordingly, the first configuration can be used to configure an uplink subband or a downlink subband on the time unit.

[0149] In some embodiments, the second configuration in the embodiments of the present disclosure is configured to configure the transmission direction of the time unit as a second direction. Wherein the second direction can be different from the first direction, for example, the first direction is uplink, and the second direction can be downlink or flexible. For another example, the first direction is downlink, and the second direction can be flexible or uplink.

[0150] In some embodiments, when the transmission direction of the sub-band configured by the first configuration above conflicts with the transmission direction of the time unit configured by the second configuration, the terminal 101 can determine its own behavior in the following any one way:

[0151] Way 1, ignoring the second configuration, and determining to send or receive the information on the time unit according to the first configuration.

[0152] In one example, the terminal 101 directly ignores the second configuration, i.e., the dedicated configuration, and determines to send or receive the information on the time unit according to the first configuration.

[0153] For example, the first configuration configures an uplink sub-band on slot#1, and the second configuration configures slot#1 as downlink. The terminal 101 directly ignores the second configuration and determines to send uplink information on slot#1 according to the first configuration.

[0154] For another example, the first configuration configures a downlink sub-band on slot#1, and the second configuration configures slot#1 as uplink. The terminal 101 directly ignores the second configuration and determines to receive downlink information on slot#1 according to the first configuration.

[0155] Way 2, not expecting the second configuration to apply to the SBFD time unit.

[0156] In some embodiments, the terminal 101 does not expect any of the second configurations to apply to the SBFD time unit.

[0157] For example, the terminal 101 does not expect any of the second configurations to apply to the SBFD time unit, such as configuring the SBFD time unit as an uplink time unit, or configuring the SBFD time unit as a downlink time unit, or configuring the SBFD time unit as a flexible time unit.

[0158] Wherein, the SBFD time unit refers to a downlink time unit or a flexible time unit configured with an uplink sub-band, or an uplink time unit or a flexible time unit configured with a downlink sub-band.

[0159] In some embodiments, the terminal 101 does not expect a specific second configuration to apply to the SBFD time unit.

[0160] In one example, the terminal 101 does not expect the second configuration configuring the SBFD time unit as an uplink time unit to be applied on the SBFD time unit.

[0161] In one example, the terminal 101 does not expect the second configuration configuring the SBFD time unit as a downlink time unit to be applied on the SBFD time unit.

[0162] In one example, the terminal 101 does not expect the second configuration configuring the SBFD time unit as a flexible time unit to be applied on the SBFD time unit.

[0163] Option 3, ignore the first configuration, and determine to transmit or receive the information on the time unit according to the second configuration.

[0164] In one example, the terminal 101 directly ignores the first configuration, and determines to transmit or receive the information on the time unit according to the second configuration.

[0165] For example, the first configuration configures an uplink subband on slot#1, and the second configuration configures slot#1 as a downlink. The terminal 101 directly ignores the first configuration, and determines to receive downlink information on slot#1 according to the second configuration.

[0166] For another example, the first configuration configures a downlink subband on slot#1, and the second configuration configures slot#1 as an uplink. The terminal 101 directly ignores the first configuration, and determines to transmit uplink information on slot#1 according to the second configuration.

[0167] Option 4, transmit or receive the information on the time unit based on the communication behavior on the SBFD time unit.

[0168] In one example, if there is only a semi-static configuration in the subband on the SBFD time unit, the terminal 101 can determine to transmit or receive the information on the time unit according to the second configuration, where the time unit can be a SBFD time unit or a non-Subband Full Duplex (non-SBFD) time unit.

[0169] Wherein, the SBFD time unit refers to a downlink time unit or a flexible time unit configured with an uplink subband, or an uplink time unit or a flexible time unit configured with a downlink subband.

[0170] Wherein, the non-SBFD time unit refers to an uplink time unit, a downlink time unit or a flexible time unit without subband configuration.

[0171] In one example, if there is a dynamically scheduled transmission in a subband on a SBFD time unit, and the time unit belongs to the SBFD time unit, considering that the dynamic scheduling has a higher priority, therefore, the terminal 101 can determine that on the time unit, the second configuration is ignored. And the transmission or reception of information can be performed based on the dynamic scheduling.

[0172] In one example, the transmission or reception of information on the time unit can be determined based on the information of the channel to be transmitted on the time unit.

[0173] Exemplarily, the information of the channel includes but is not limited to the channel type and / or the channel priority.

[0174] For example, the channel to be transmitted on the time unit is a downlink control channel, and the terminal 101 can receive the downlink control channel.

[0175] For another example, the priority of the first channel is higher than the priority of the second channel, and the first channel is an uplink channel, and the terminal 101 can transmit the first channel.

[0176] The above is only an exemplary description, and the disclosure does not limit the specific implementation of the terminal 101 determining to transmit or receive information on the time unit according to the first configuration or the second configuration according to the predefined rule.

[0177] In the above embodiment, when the transmission direction of the subband configured by the first configuration conflicts with the transmission direction of the time unit configured by the second configuration, the terminal behavior is clear, the reliability of the SBFD communication is improved, and the availability is high.

[0178] In some embodiments, when the transmission direction of the subband configured by the first configuration conflicts with the transmission direction of the time unit configured by the second configuration, the network device 102 can determine its behavior in the following any one way:

[0179] Method 1, ignoring the second configuration, and determining to receive or transmit the information on the time unit according to the first configuration.

[0180] In one example, the network device ignores the second configuration, and determines to receive or transmit the information on the time unit according to the first configuration.

[0181] For example, the first configuration configures an uplink subband on slot#1, and the second configuration configures slot#1 as downlink, and the network device 102 still receives uplink information on slot#1 according to the first configuration.

[0182] For example, the first configuration configures a downlink sub-band on slot#1, and the second configuration configures slot#1 as an uplink. The network device 102 still transmits downlink information on slot#1 according to the first configuration.

[0183] Option 2: Avoid the second configuration from being applied on the SBFD time unit.

[0184] In some embodiments, the network device 102 can avoid any second configuration from being applied on the SBFD time unit.

[0185] In some embodiments, the network device 102 can avoid a specific second configuration from being applied on the SBFD time unit.

[0186] In one example, the network device 102 can avoid the second configuration that configures the SBFD time unit as an uplink time unit from being applied on the SBFD time unit. It can be understood that at this time, the network device 102 can apply the second configuration that configures the SBFD time unit as a downlink time unit or a flexible time unit on the SBFD time unit.

[0187] In one example, the network device 102 can avoid the second configuration that configures the SBFD time unit as a downlink time unit from being applied on the SBFD time unit. It can be understood that at this time, the network device 102 can apply the second configuration that configures the SBFD time unit as an uplink time unit or a flexible time unit on the SBFD time unit.

[0188] In one example, the network device 102 can avoid the second configuration that configures the SBFD time unit as a flexible time unit from being applied on the SBFD time unit. It can be understood that at this time, the network device 102 can apply the second configuration that configures the SBFD time unit as an uplink time unit or a downlink time unit on the SBFD time unit.

[0189] Option 3: Ignore the first configuration, and determine to receive or transmit the information on the time unit according to the second configuration.

[0190] For example, the first configuration configures an uplink sub-band on slot#1, and the second configuration configures slot#1 as a downlink. The network device 102 determines to transmit downlink information on slot#1 according to the second configuration.

[0191] For example, the first configuration configures an uplink sub-band on slot#1, and the second configuration configures slot#1 as a downlink. The network device 102 determines to transmit downlink information on slot#1 according to the second configuration.

[0192] Option 4, based on the communication behavior on the SBFD time unit, the receiving or sending of the information on the time unit.

[0193] In one example, if there is only semi-static configuration in the sub-band on the SBFD time unit, the network device 102 can determine to receive or send the information on the time unit according to the second configuration, where the time unit can be the SBFD time unit or the non-SBFD time unit.

[0194] In one example, if there is dynamic scheduling transmission in the sub-band on the SBFD time unit, and the time unit belongs to the SBFD time unit, considering that the dynamic scheduling has higher priority, the network device 102 can determine to ignore the second configuration on the time unit. And can perform the receiving or sending of the information based on the dynamic scheduling.

[0195] In one example, the receiving or sending of the information on the time unit can be determined based on the information of the channel for transmission on the time unit. The specific implementation process is similar to the terminal side, and will not be repeated here.

[0196] In the above embodiments, when the transmission direction of the sub-band configured by the first configuration conflicts with the transmission direction of the time unit configured by the second configuration, the behavior of the network device is clear, and the reliability and availability of the SBFD communication are improved.

[0197] In some embodiments, the terminal behavior matches the network device behavior, specifically including:

[0198] In one example, the terminal 101 ignores the second configuration and determines to send or receive the information on the time unit according to the first configuration, and the network device 102 also ignores the second configuration and determines to receive or send the information on the time unit according to the first configuration.

[0199] In one example, the terminal 101 does not expect the second configuration to be applied to the SBFD time unit, and the network device 102 avoids applying the second configuration to the SBFD time unit.

[0200] Wherein, the second configuration can be any configuration, or a specific configuration, the specific content will not be repeated here.

[0201] In one example, the terminal 101 ignores the first configuration and determines to send or receive the information on the time unit according to the first configuration, and the network device 102 also ignores the first configuration and determines to receive or send the information on the time unit according to the first configuration.

[0202] In one example, the terminal 101 and the network device 102 are both based on the communication behavior on the SBFD time unit on which the information is sent or received.

[0203] In the above embodiment, when the transmission direction of the sub-band configured by the first configuration conflicts with the transmission direction of the time unit configured by the second configuration, the behavior of the network device can be ensured to match the behavior of the terminal, and the reliability of the SBFD communication is improved.

As shown in FIG. 3B, the embodiment of the present disclosure relates to a communication method, which can be performed by the network device 102, and the above method comprises:

[0238] In some embodiments, the execution order of steps S3201 to S3203 is not limited.

[0239] In the above embodiments, when the transmission direction of the sub-band configured by the first configuration conflicts with the transmission direction of the time unit configured by the second configuration, the behavior of the network device is determined, ensuring that the behavior of the network device matches the behavior of the terminal, improving the reliability of SBFD communication and the availability.

[0240] The above process is further illustrated as follows.

[0241] In the embodiments of the present disclosure, when a network device, for example, a base station, indicates the transmission direction of the semi-static symbol configured with the SBFD subband through UE-dedicated TDD-UL-DL configuration, the base station and the terminal determine the transmission behavior on the SBFD symbol according to a predefined rule.

[0242] Terminal side:

[0243] The terminal receives the configuration information of the base station, determines that there is a SBFD subband on the semi-static flexible symbol, and transmits or receives data according to the indication of the base station. When the base station indicates the transmission direction of the semi-static symbol configured with the SBFD subband through UE-dedicated TDD-UL-DL configuration, the terminal determines the transmission behavior according to the following method:

[0244] First, the terminal is a terminal supporting full duplex operation.

[0245] Second, the semi-static flexible symbol is a flexible symbol configured through tdd-UL-DL-ConfigurationCommon.

[0246] Third, the terminal transmits data in the UL subband on the semi-static flexible symbol or receives data in the DL subband on the semi-static flexible symbol.

[0247] Method 1: When the terminal receives the UE-dedicated TDD-UL-DL configuration configuration information, the terminal ignores the UE-dedicated configuration information and still performs the transmission and reception process according to the configuration of the SBFD subband.

[0248] Method 2: The terminal does not expect that the base station-specific UE-dedicated TDD-UL-DL configuration configuration information is applied to the SBFD symbol.

[0249] The specific UE-dedicated TDD-UL-DL configuration is any configuration.

[0250] Or, the specific UE-dedicated TDD-UL-DL configuration is a TDD configuration indicating the SBFD symbol as a UL symbol.

[0251] Or, the specific UE-dedicated TDD-UL-DL configuration is a TDD configuration indicating the SBFD symbol as a DL symbol.

[0252] Method 3: The terminal determines the transmission direction of the corresponding OFDM symbol according to the UE-dedicated TDD-UL-DL configuration, and ignores the SBFD subband related configuration.

[0253] Method 4: The terminal determines the type or direction of the OFDM symbol according to its transmission / reception characteristics on the SBFD symbol.

[0254] If there is only semi-statically configured related transmission on the SBFD symbol, the terminal determines the symbol type or direction according to the UE-dedicated TDD-UL-DL configuration.

[0255] If there is base station dynamically scheduled related transmission on the SBFD symbol, the terminal ignores the UE-dedicated TDD-UL-DL configuration on the SBFD symbol.

[0256] Further, the terminal can determine the type or direction of the OFDM symbol according to the channel type, priority, etc. transmitted on the OFDM symbol.

[0257] The type or direction of the OFDM symbol means that the OFDM symbol is a SBFD symbol or a non-SBFD symbol.

[0258] Base station side:

[0259] The base station sends configuration information to the terminal, indicating that there is a SBFD subband on the semi-static flexible symbol, and transmits or receives data according to the base station indication. When the base station indicates the transmission direction of the semi-static symbol configured with the SBFD subband through the UE-dedicated TDD-UL-DL configuration, the transmission behavior is determined according to the following method.

[0260] The terminal is a terminal supporting full duplex operation. The semi-static flexible symbol is a flexible symbol configured by tdd-UL-DL-ConfigurationCommon. The terminal transmits data in the UL subband on the semi-static flexible symbol or receives data in the DL subband on the semi-static flexible symbol.

[0261] Method 1: When the base station provides the terminal with UE-dedicated TDD-UL-DL configuration configuration information, the base station still performs the transceiving process according to the configuration of the SBFD subband.

[0262] Method 2: The base station avoids applying specific UE-dedicated TDD-UL-DL configuration configuration information to the SBFD symbol.

[0263] The specific UE-dedicated TDD-UL-DL configuration is any configuration.

[0264] Alternatively, the specific UE-dedicated TDD-UL-DL configuration is a TDD configuration indicating that the SBFD symbol is an UL symbol.

[0265] Alternatively, the specific UE-dedicated TDD-UL-DL configuration is a TDD configuration indicating that the SBFD symbol is a DL symbol.

[0266] Method 3: The base station determines the transmission direction of the corresponding OFDM symbol according to the UE-dedicated TDD-UL-DL configuration, and considers that the SBFD subband related configuration is not effective.

[0267] Method 4: The base station determines the type or direction of the OFDM symbol according to its transmission / reception characteristics on the SBFD symbol.

[0268] If there is only semi-statically configured related transmission on the SBFD symbol, the terminal determines the symbol type or direction according to the UE-dedicated TDD-UL-DL configuration.

[0269] If there is a related transmission dynamically scheduled by the base station on the SBFD symbol, the terminal ignores the UE-dedicated TDD-UL-DL configuration on the SBFD symbol.

[0270] Further, the terminal can determine the type or direction of the OFDM symbol according to the channel type, priority, etc. transmitted on the OFDM symbol.

[0271] The type or direction of the OFDM symbol means that the OFDM symbol is an SBFD symbol or a non-SBFD symbol.

[0272] Embodiments of the present disclosure also propose an apparatus for implementing any of the above methods, for example, an apparatus comprising units or modules for implementing the steps performed by each node (e.g., terminal, network device) in any of the above methods.

[0273] It should be understood that the division of each unit or module in the above apparatus is only a logical function division, and all or part of them can be integrated into a physical entity or physically separated in actual implementation. In addition, the units or modules in the apparatus can be implemented in the form of processor calling software: for example, the apparatus includes a processor, the processor is connected with a memory, the memory stores instructions, and the processor calls the instructions stored in the memory to realize the functions of any of the above methods or the units or modules of the above apparatus, wherein the processor is a general processor such as a central processing unit (CPU) or a microprocessor, and the memory is a memory in the apparatus or a memory outside the apparatus.
