Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and more specifically, to a communication method, a terminal device, a network terminal device, and a communication device. Background Art

[0002] Data is transmitted in frames on wireless networks. Each frame is divided into subframes of equal length. Each subframe is further divided into several time slots. Each time slot is usually composed of 14 orthogonal frequency division multiplexing (OFDM) symbols.

[0003] Integrated Sensing and Communication (ISAC), also known as synaesthesia integration, means that the communication system can perceive the environment during the communication process with the equipment, that is, the communication system has both communication and perception functions. The realization of synaesthesia integration is conducive to expanding the service capabilities of the communication system and can be widely used in scenarios such as smart transportation, low-altitude security, and climate and environmental detection.

[0004] In some frame structure configuration methods, the frame structure configuration is usually completed with the core of meeting the communication signal transmission requirements, without considering the transmission requirements of the perception signal, and it is difficult to apply to the synaesthesia integration scenario.

[0005] Therefore, there is a need to improve the frame structure configuration method. Summary of the invention

[0043] Various exemplary embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure.

[0044] The following description of at least one exemplary embodiment is in fact merely illustrative and is in no way intended to limit the present disclosure and its application or use. That is, the structures and methods herein are shown in an exemplary manner to illustrate different embodiments of the structures and methods in the present disclosure. However, those skilled in the art will appreciate that they merely illustrate exemplary ways of the present disclosure that can be implemented, rather than exhaustive ways. In addition, the drawings need not be drawn to scale, and some features may be enlarged to illustrate the details of specific components.

[0045] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.

[0046] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0047] In a communication system, the frame structure can usually be configured. For example, the frame structure configuration in units of OFDM symbols can be completed through corresponding signaling to define the time allocation of communication signals (such as uplink communication signals and downlink communication signals), so as to facilitate the network to efficiently allocate wireless resources. Among them, the types of OFDM symbols may include uplink communication symbols (U), downlink communication symbols (D) and flexible symbols (F). Uplink communication symbols and downlink communication symbols can be used for the transmission of uplink communication signals and downlink communication signals, respectively, and flexible symbols are other transmission symbols that are not configured as uplink communication symbols and downlink communication symbols.

[0048] The frame structure configuration can be notified to the terminal device through the corresponding indication information, so as to allocate the corresponding parameter set and optimize the scheduling of resources according to the frame structure configuration. For example, the terminal device can be instructed to complete the corresponding frame structure configuration through downlink control information (Downlink Control Information, DCI).

[0049] DCI Format 2_0 is defined in the Third Generation Partnership Project (3GPP) TS38.212 to notify the terminal device of the time slot format configuration (i.e., the configuration of each symbol in the time slot). 3GPP TS 38.213 provides the steps and rules for completing the time slot configuration through DCI format 2_0, and provides 56 pre-defined time slot format configurations, as shown in Table 1 below:

[0050] Table 1 Time slot format configuration table

[0051] In this document, the time slot format configuration table shown in Table 1 is also referred to as the first table. Each time slot format configuration in the first table includes configuration information of at least one of an uplink communication symbol (U), a downlink communication symbol (D), and a flexible symbol (F). The configuration information may include, for example, the number and position of a symbol in a time slot.

[0052] In some frame structure configuration methods, the frame structure is usually configured with the core of meeting the communication signal transmission requirements. For example, the configuration of the symbols in each time slot of the frame structure is completed according to the 56 pre-defined time slot formats in the first table, and the transmission requirements of the perception signal are not considered, making it difficult to transmit the perception signal according to the configured frame structure. For example, the perception signal may be transmitted in the same symbol as the communication signal, resulting in a conflict, which makes it difficult to apply to the synaesthesia integration scenario.

[0053] In order to solve the above problems, the present disclosure proposes a communication method, introduces perception symbols, and dynamically instructs the terminal device to complete the configuration of the perception symbols in the time slot through DCI, so as to achieve flexible resource configuration according to the time slot configuration, which is conducive to the transmission of perception signals, provides support for the execution of perception services, and can expand the service capabilities of the communication network system, and realize a flexible network with collaborative integration of communication and perception.

[0054] According to one aspect of the present disclosure, a communication method 100 that can be executed by a terminal device is provided, such as Figure 1 As shown, a communication method 100 according to an exemplary embodiment of the present disclosure may include:

[0055] Step S110, receiving downlink control information; and

[0056] Step S120: determining configuration information of one or more time slots according to the downlink control information.

[0057] Among them, the configuration information of at least one time slot among the one or more time slots includes perception symbol configuration information to provide support for the transmission of corresponding perception signals to meet the diverse needs in the synaesthesia integration scenario.

[0058] Terminal equipment, also known as user equipment (UE), terminal, etc. Terminal equipment is a device with wireless transceiver function, which can communicate with one or more core networks (CN) through the access network equipment in the (radio) access network ((R)AN). It can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water surface, such as on ships; it can also be deployed in the air, such as on airplanes, balloons or satellites. Terminal equipment can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc.

[0059] When the Radio Resource Control (RRC) layer is configured with a SlotFormat Indicator (SFI), the network can distribute and configure SFI-RNTI, dci-PayloadSize and positionInDCI to the UE through corresponding RRC signaling, and can also instruct the UE to configure the time-frequency resources corresponding to CORESET / Searchspace to receive DCI (for example, DCI format 2_0).

[0060] Taking into account that the forms of perception signals used in different perception scenarios may be different, for example, in one perception scenario, a perception signal in the form of a continuous wave may be used for perception, or, in another perception scenario, a perception signal in the form of a pulse wave may be used for perception, or, in yet another perception scenario, both a perception signal in the form of a continuous wave and a perception signal in the form of a pulse wave may be used for perception. The present disclosure introduces two different perception symbols, namely a first type of perception symbol, such as a continuous wave perception symbol (C), and a second type of perception symbol different from the first type of perception symbol, such as a pulse wave perception symbol (P), which are respectively used for the transmission of different types of perception signals (such as a continuous wave perception signal and a pulse wave perception signal), thereby providing a more flexible perception symbol configuration.

[0061] In some embodiments, the downlink control information may include one or more slot format indication indexes (SFIIndex), wherein one SFI Index may be used to determine the configuration information of one slot. In this way, the UE may obtain one or more SFI Indexes by parsing the DCI to determine the configuration information of one or more slots, and the UE may determine the configuration information of each slot in multiple slots of each downlink bandwidth part (DLBWP) or each uplink bandwidth part (UL BWP) starting from the slot in which the UE detects the DCI according to the SFI Index in the DCI. The configuration information of each slot may include configuration information of at least one of an uplink communication symbol (U), a downlink communication symbol (D), a flexible symbol (F), a first type of perception symbol, and a second type of perception symbol. Alternatively, in some other embodiments, the downlink control information may include a first high-level parameter (slotFormatCombinationId), and the first high-level parameter indicates one or more SFIIndex. In this way, the UE may obtain the first high-level parameter by parsing the DCI to determine the configuration information of each slot in one or more slots according to the one or more SFI Indexes indicated by the first high-level parameter. Compared with directly transmitting one or more SFI Indexes, transmitting the first high-level parameter indicating one or more SFI Indexes can reduce the amount of data required to be transmitted by the DCI and improve the configuration efficiency of the frame structure.

[0062] In some embodiments, an SFI Index may correspond to a time slot format configuration, wherein the time slot format configuration may be generated based on at least one of an uplink communication symbol (U), a downlink communication symbol (D), a flexible symbol (F), a first type of perception symbol, and a second type of perception symbol, and the above-mentioned time slot format configuration may be pre-configured in the UE so that the UE can obtain the corresponding time slot format configuration according to the SFI Index, thereby determining the configuration information of the corresponding time slot and improving the configuration efficiency.

[0063] In some embodiments, the time slot format configuration may be encapsulated, for example, into a table, and pre-configured in the UE, wherein an SFI Index may indicate the position of a time slot format configuration in the table, so that the UE can find the corresponding time slot format configuration from the table according to the SFI Index, thereby determining the configuration information of the corresponding time slot.

[0064] In a specific example, the first table can be expanded according to at least one of the first type of perceptual symbols and the second type of perceptual symbols to add configuration information about the first type of perceptual symbols and the second type of perceptual symbols in the first table, thereby providing more time slot format configurations different from the first table, that is, at least one time slot format configuration in the expanded first table includes configuration information of at least one of the first type of perceptual symbols and the second type of perceptual symbols. Among them, an SFI Index can indicate the position of a time slot format configuration in the first table. In this way, the configuration of symbols in each time slot of the frame structure, especially the configuration of the first type of perceptual symbols and the second type of perceptual symbols, can be completed according to the time slot format configuration in the first table.

[0065] In a specific example, taking the first type of perception symbol as a continuous wave perception symbol (C) and the second type of perception symbol as a pulse wave perception symbol (P) as an example, the expanded first table may be as shown in the following Table 2:

[0066] Table 2 The first table after expansion

[0067] Here, for the sake of brevity, Table 2 mainly shows the expanded portion of the first table after expansion relative to the first table shown in Table 1, and omits the portion repeated with the first table shown in Table 1. Table 2 exemplarily shows a configuration method of the first table after expansion of the present disclosure, and is not necessarily required to be complete. It should be understood that in other embodiments, Table 2 may also have other configuration methods, and the configuration information about the communication symbol, the flexible symbol, the first type of perception symbol, and the second type of perception symbol may be included in Table 2 in other forms.

[0068] In some cases, in addition to indicating the frame structure configuration to the UE through DCI, the frame structure configuration may also be indicated to the UE through high-level information. The high-level information may include a first semi-static time slot format configuration tdd-UL-DL-ConfigurationCommon, which is used to indicate the time slot format configuration to the UE of the specified cell, or the high-level information may include a second semi-static time slot format configuration tdd-UL-DL-ConfigurationDedicated, which is used to indicate the time slot format configuration to the specified UE.

[0069] In some embodiments, the UE may receive high-level information and may determine the time slot format configuration of the frame structure based on the received high-level information, so that the initial configuration of each time slot in the frame structure may be determined. Then, the configuration information of one or more time slots in the frame structure may be determined based on the DCI and the time slot format configuration of the frame structure. In this way, when the initial configuration of the frame structure has been completed through high-level information, the configuration information of one or more time slots in the frame structure may also be modified through the DCI, as will be described in detail later.

[0070] In the case where the initial configuration of a time slot position is an uplink communication symbol, the DCI indicates that the time slot position is a downlink communication symbol, or in the case where the initial configuration of a time slot position is a downlink communication symbol, the DCI indicates that the time slot position is an uplink communication symbol, which may cause the UE to be unable to correctly configure the time slot format of the frame structure, so such contradictions should be avoided as much as possible. In some cases, the network end can adjust or select parameters in the DCI according to the initial configuration of each time slot in the frame structure to avoid indicating contradictory configuration information to the UE.

[0071] In some embodiments, one or more time slots may be continuous time slots starting from the time slot in which the UE receives the DCI, that is, the configuration information of multiple continuous time slots starting from the time slot in which the DCI is received may be determined through the DCI. Alternatively, in some embodiments, one or more time slots may be continuous flexible time slots starting from the time slot in which the UE receives the DCI, that is, the configuration information of multiple continuous flexible time slots starting from the time slot in which the DCI is received may be determined through the DCI. A flexible time slot is a time slot that is pre-configured to include at least one flexible symbol, wherein whether each time slot starting from the time slot in which the DCI is received is a flexible time slot can be determined by the time slot format configuration of the frame structure determined above according to the high-level information.

[0072] In order to further improve the flexibility of time slot format configuration and improve the applicability in different synaesthesia integration scenarios, in some embodiments, the downlink control information may include at least one of a first indication parameter (ContinuousSensingSymbolLength) and a second indication parameter (PulseSensingSymbolLength). The first indication parameter may be used to indicate the first multiple of the symbol duration of the first type of sensing symbol relative to the symbol duration of the communication symbol, and the second indication parameter may be used to indicate the second multiple of the symbol duration of the second type of sensing symbol relative to the symbol duration of the communication symbol.

[0073] Some embodiments of the present disclosure are described below using the first type of perception symbol being a continuous wave perception symbol and the second type of perception symbol as an example. It should be understood that in other embodiments, the first type of perception symbol may also be other types of perception symbols, and the second type of perception symbol may also be other types of perception symbols accordingly.

[0074] The symbol duration of the continuous wave perception symbol and the symbol duration of the pulse wave perception symbol can be expressed as:

[0075] = * ;

[0076] = * .

[0077] in, represents the symbol duration of the continuous wave perception symbol, The symbol duration representing the pulse wave perception symbol, represents the symbol duration of the communication symbol, is the first multiple indicated by the first indicator parameter, The second multiple indicated by the second indication parameter. In some specific examples, the symbol duration of the continuous wave perception symbol and the pulse wave perception symbol may be different from the symbol duration of the communication symbol, that is, the first multiple and the second multiple may not be 1. The configuration of the first indication parameter and the second indication parameter in the RRC layer may be as follows:

[0078] ContinuousSensingSymbolLength INTEGER(0..maxContinuousSensingSymbolLength) OPTIONAL, -- Need R;

[0079] PulseSensingSymbolLength INTEGER(0..maxPulseSensingSymbolLength)OPTIONAL, -- Need R.

[0080] In some embodiments, the first indication parameter and the second indication parameter are optional. When the first indication parameter is not configured in the DCI, the symbol duration of the continuous wave perception symbol may be a default multiple of the symbol duration of the communication symbol. When the second indication parameter is not configured in the DCI, the symbol duration of the pulse wave perception symbol may be a default multiple of the symbol duration of the communication symbol. The default multiple is, for example, 0, that is, when the first indication parameter or the second indication parameter is not configured in the DCI, it indicates that the continuous wave perception symbol or the pulse wave perception symbol is not configured.

[0081] Accordingly, the UE may obtain the first indication parameter and the second indication parameter by parsing the DCI to determine the symbol duration of the first type of perception symbol and the symbol duration of the second type of perception symbol. Figure 2 As shown, determining the configuration information of one or more time slots according to the downlink control information may include:

[0082] Step S121, determining whether the downlink control information includes at least one of the first indication parameter and the second indication parameter;

[0083] Step S122, in response to the downlink control information including a first indication parameter, determining that a symbol duration of a first type of perception symbol in one or more time slots is a first multiple of a symbol duration of a communication symbol;

[0084] Step S123, in response to the downlink control information including a second indication parameter, determining that the symbol duration of the second type perception symbol in one or more time slots is a second multiple of the symbol duration of the communication symbol;

[0085] Step S124, in response to the downlink control information not including the first indication parameter, determining that the symbol duration of the first type of perception symbol in one or more time slots is a default multiple of the symbol duration of the communication symbol;

[0086] Step S125: in response to the downlink control information not including the second indication parameter, determining that the symbol duration of the second type perception symbol in one or more time slots is a default multiple of the symbol duration of the communication symbol.

[0087] In this way, the corresponding first indication parameter and / or second indication parameter can be flexibly set according to the perception scenario setting. For example, the corresponding first indication parameter and / or second indication parameter can be set according to the requirement of the perception coverage distance of the perception signal in the perception service.

[0088] For continuous wave sensing signals, reception and transmission can usually be performed simultaneously. The symbol duration of the continuous wave sensing symbol can be set according to the corresponding coverage distance requirement, for example, according to the maximum distance requirement of the echo received within the symbol duration of the continuous wave sensing symbol. In addition to the symbol duration, the sensing capability of the continuous wave signal is mainly limited by equipment parameters such as the base station continuous wave transmission power and antenna gain.

[0089] For pulse wave sensing signals, such as Figure 3 As shown, the symbol duration of a pulse perception symbol Within τ time, it is used to send pulse wave sensing signal, and then Time is used to switch from the sending state to the receiving state. time is used to receive the echo signal, and then The time is used to switch from the receiving state to the sending state. The symbol duration of the pulse wave sensing symbol can be set according to the corresponding coverage distance requirements. For example, the time used to receive the pulse echo signal after excluding the pulse transmission and antenna transceiver switching time. The maximum distance required for the echo received within is determined.

[0090] The following reference Figures 4 to 8 Some embodiments of the present disclosure are described for configuring one or more time slots through DCI.

[0091] The UE may determine the time slot format configuration of the frame structure according to the high-layer information (eg, the first semi-static time slot format configuration tdd-UL-DL-ConfigurationCommon and / or the second semi-static time slot format configuration tdd-UL-DL-ConfigurationDedicated). Figure 4 As shown, at this time, the frame structure determined according to the high-level information can be cycled according to the downlink time slot (DS), downlink time slot (DS), flexible time slot (FS), flexible time slot (FS) and uplink time slot (US) as a cycle, wherein the downlink time slot (DS) indicates that all symbols in the time slot are downlink communication symbols (D), the uplink time slot (US) indicates that all symbols in the time slot are uplink communication symbols (U), and the flexible time slot (FS) indicates that the time slot includes at least one flexible symbol (F). The following is based on Figure 4 The time slot format configuration of the frame structure shown is used to describe some examples of dynamically configuring time slots according to DCI.

[0092] Figure 5 A first example of dynamically configuring time slots according to DCI is shown, wherein an exemplary parameter configuration in the DCI may be as follows:

[0093] positionInDCI: 0;

[0094] ContinuousSensingSymbolLength: 1;

[0095] PulseSensingSymbolLength: 1;

[0096] SlotFormatCombinationId: 0-3;

[0097] SlotFormatCombinationId 0: slotFormats 136, 0, 0, 2;

[0098] SlotFormatCombinationId 1: slotFormats 122, 111, 75, 64;

[0099] SlotFormatCombinationId 2: slotFormats 121, 132, 0, 8;

[0100] SlotFormatCombinationId 3: slotFormats 81, 60, 0, 8.

[0101] Among them, the first high-level parameter SlotFormatCombinationId can be represented by 2 bits, that is, 00, 01, 10, and 11 can respectively represent SlotFormatCombinationId 0, SlotFormatCombinationId 1, SlotFormatCombinationId 2, and SlotFormatCombinationId 3. positionInDCI indicates the position of SlotFormatCombinationId in DCI. For example, positionInDCI is 0, indicating that SlotFormatCombinationId is read from the starting position of DCI. In the first example, after the UE decodes the DCI (for example, DCI format 2_0), it takes 2 bits from the starting position of DCI to obtain SlotFormatCombinationId. In the first example, the result of taking 2 bits from the starting position of DCI is the binary number "00", which indicates SlotFormatCombinationId 0; slotFormats 136, 0, 0, 2 indicates that the slot format indication index (SFIIndex) corresponding to SlotFormatCombinationId 0 is 136, 0, 0, 2. ContinuousSensingSymbolLength is 1, which means that the symbol duration of the continuous wave sensing symbol is 1 times the symbol duration of the communication symbol, that is, = ; PulseSensingSymbolLength is 1, which means that the symbol duration of the pulse wave sensing symbol is 1 times the symbol duration of the communication symbol, that is, =* In the first example, the corresponding time slot format configuration can be determined from the expanded first table according to the time slot format indication index (SFI Index) 136, 0, 0, 2 corresponding to SlotFormatCombinationId 0, so that the configuration information of 4 consecutive time slots starting from the time slot where the DCI is received can be determined, such as Figure 5 The first example can be applicable to the base station's self-transmitting and self-receiving sensing mode, that is, the base station sends and receives sensing signals, and the configuration information of multiple consecutive time slots can be determined through DCI indication, wherein the sensing symbols can reuse the original downlink communication symbols.

[0102] In other examples, SlotFormatCombinationId may also be represented by n bits (n is not 2) to indicate 2 n There are different SFI Index combinations. Accordingly, the UE can read n bits from the starting position of the DCI to obtain the corresponding SlotFormatCombinationId.

[0103] Figure 6 A second example of dynamically configuring time slots according to DCI is shown, wherein an exemplary parameter configuration in the DCI may be as follows:

[0104] positionInDCI: 0

[0105] ContinuousSensingSymbolLength: 1;

[0106] PulseSensingSymbolLength: 0;

[0107] SlotFormatCombinationId: 0-3;

[0108] SlotFormatCombinationId 0: slotFormats 136, 0, 0, 2;

[0109] SlotFormatCombinationId 1: slotFormats 122, 111, 75, 64;

[0110] SlotFormatCombinationId 2: slotFormats 121, 132, 0, 8;

[0111] SlotFormatCombinationId 3: slotFormats 81, 60, 0, 8.

[0112] Considering that when the subcarrier spacing (SCS) is 120KHz, the millimeter wave communication symbol duration is 8.9286 us, corresponding to the maximum coverage distance of 1.4881km, which is sufficient to meet the short-range perception coverage, it is prioritized to make the symbol duration of the continuous wave perception symbol equal to the symbol duration of the uplink and downlink communication symbols to simplify the frame structure configuration.

[0113] After the UE decodes the DCI (e.g., DCI format 2_0), it can obtain the first indication parameter ContinuousSensingSymbolLength and the second indication parameter PulseSensingSymbolLength, which are 1 and 0 respectively in the second example. ContinuousSensingSymbolLength is 1, indicating that the symbol duration of the continuous wave sensing symbol is a multiple of the symbol duration of the communication symbol, that is, = ; PulseSensingSymbolLength is 0, indicating that there is no pulse wave sensing symbol under this DCI configuration. In the second example, the result of taking 2 bits from the starting position of the DCI is the binary number "11", which means SlotFormatCombinationId 3, and the corresponding time slot format indication index (SFI Index) is 81, 60, 0, 8. According to the SFI Index, the corresponding time slot format configuration can be determined from the expanded first table, so that the configuration information of 4 consecutive flexible time slots starting from the time slot where the DCI is received can be determined, such as Figure 6 According to the second example, the configuration of the continuous wave perception symbol in the time slot can be completed.

[0114] Figure 7 A third example of dynamically configuring time slots according to DCI is shown, wherein an exemplary parameter configuration in the DCI may be as follows:

[0115] positionInDCI: 0

[0116] ContinuousSensingSymbolLength: 0;

[0117] PulseSensingSymbolLength: 2;

[0118] SlotFormatCombinationId: 0-3;

[0119] SlotFormatCombinationId 0: slotFormats 136, 0, 0, 2;

[0120] SlotFormatCombinationId 1: slotFormats 122, 111, 75, 64;

[0121] SlotFormatCombinationId 2: slotFormats 121, 132, 0, 8;

[0122] SlotFormatCombinationId 3: slotFormats 81, 60, 0, 8.

[0123] Considering that when the subcarrier spacing (SCS) is 120KHz, the millimeter wave communication symbol duration is 8.9286 us. Excluding the pulse transmission time and the antenna transmission and reception switching time, the echo reception time is not expected to cover a distance of 1km. Therefore, the symbol duration of the pulse wave sensing symbol needs to be extended to meet the coverage requirements. In the third example, the symbol duration of the pulse wave sensing symbol is extended to twice the symbol duration of the communication symbol, that is, =2* .

[0124] After the UE decodes the DCI (e.g., DCI format 2_0), it can obtain the first indication parameter ContinuousSensingSymbolLength and the second indication parameter PulseSensingSymbolLength, which are 0 and 2 respectively in the third example. ContinuousSensingSymbolLength is 0, indicating that there is no continuous wave sensing symbol under this DCI configuration; PulseSensingSymbolLength is 2, indicating that =2* , with the symbol duration of the communication symbol as the unit symbol duration, and a pulse wave symbol occupies two unit symbol durations. In the third example, the result of taking 2 bits from the starting position of the DCI is the binary number "10", which means SlotFormatCombinationId 2, and the corresponding time slot format indication index (SFI Index) is 121, 132, 0, 8. According to the SFI Index, the corresponding time slot format configuration can be determined from the expanded first table, so that the configuration information of 4 consecutive flexible time slots starting from the time slot where the DCI is received can be determined, such as Figure 7 According to the third example, the configuration of the pulse wave perception symbol in the time slot can be completed.

[0125] Figure 8 A fourth example of dynamically configuring time slots according to DCI is shown, wherein an exemplary parameter configuration in the DCI may be as follows:

[0126] positionInDCI: 0

[0127] ContinuousSensingSymbolLength: 0.5;

[0128] PulseSensingSymbolLength: 1;

[0129] SlotFormatCombinationId: 0-3;

[0130] SlotFormatCombinationId 0: slotFormats 136, 0, 0, 2;

[0131] SlotFormatCombinationId 1: slotFormats 122, 111, 75, 64;

[0132] SlotFormatCombinationId 2: slotFormats 121, 132, 0, 8;

[0133] SlotFormatCombinationId 3: slotFormats 81, 60, 0, 8.

[0134] Considering that when the subcarrier spacing (SCS) is 60KHz, the symbol duration of the millimeter wave communication symbol is 17.8571us. For continuous wave sensing signals, 8.9286us can meet the short-range sensing coverage, so consider compressing the symbol duration of continuous wave sensing symbols to save corresponding resources; for pulse wave sensing symbols, 17.8571us is enough to make the echo reception time meet the coverage distance requirements, so consider making the symbol duration of the pulse wave sensing symbol equal to the symbol duration of the communication symbol.

[0135] After the UE decodes the DCI (eg, DCI format 2_0), it can obtain the first indication parameter ContinuousSensingSymbolLength and the second indication parameter PulseSensingSymbolLength, which are 0.5 and 1 respectively in the fourth example, that is, =0.5* = , with the symbol duration of the communication symbol as the unit symbol duration, one unit symbol duration may include two continuous wave perception symbols, or one unit symbol duration may include one pulse wave perception symbol. In the fourth example, the result of taking 2 bits from the starting position of the DCI is the binary number "01", which means SlotFormatCombinationId 1, and the corresponding time slot format indication index (SFI Index) is 122, 111, 75, 64. According to the SFI Index, the corresponding time slot format configuration can be determined from the expanded first table, so that the configuration information of 4 consecutive flexible time slots starting from the time slot where the DCI is received can be determined, such as Figure 8 According to the fourth example, the configuration of the continuous wave perception symbol and the pulse wave perception symbol in the time slot can be completed, and the configuration of the continuous wave perception symbol and the pulse wave perception symbol in different repetition periods of the frame structure can be completed.
