Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0002] In the process of the evolution of the fifth-generation (5G) mobile communication system to 5G-advanced (5G-A) technology, communication perception technology is considered to be one of the key technologies that can expand the service capabilities of mobile communication networks. The core idea of ​​this communication perception technology is to add perception capabilities to the mobile communication network and build capabilities such as detection, tracking and imaging of targets, so that the two capabilities of communication and perception can be integrated into one network to achieve harmonious coexistence and mutual benefit. The principle of perception technology is that the transmitting device sends radio waves (i.e., perception signals) in a specific direction. When the radio waves are irradiated on the surface of the target, reflected radio waves (i.e., echo signals of the perception signals) are formed. The receiving device receives and processes the reflected radio waves to obtain perception data, such as the location, speed or type of the target.

[0003] Currently, the communication frame structure is scheduled in time slots, as follows Figure 1 As mentioned above, a time slot is a continuous period of time. In the 5G NR system, a time slot includes 14 OFDM symbols. The time slot length corresponding to the 15kHz subcarrier spacing is 1ms, and the time slot length corresponding to the 30kHz subcarrier spacing is 0.5ms. Whether the base station sends a signal to the terminal or the terminal sends a signal to the base station, the time slot is used as a unit, and the time length occupied is short, resulting in low speed perception resolution when the communication and perception signals are multiplexed, making it difficult to perceive targets with lower speeds.

[0088] The network equipment and terminal equipment can be fixed or movable. The network equipment and terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on aircraft, balloons and artificial satellites in the air. The embodiments of the present application do not limit the application scenarios of the network equipment and terminal equipment.

[0089] The roles of network devices and terminal devices can be relative, for example, Figure 2 The helicopter or drone 120i in the figure can be configured as a mobile network device. For the terminal devices 120j that access the wireless access network 100 through 120i, the terminal device 120i is a network device; but for the network device 110a, 120i is a terminal device, that is, 110a and 120i communicate through the wireless air interface protocol. Of course, 110a and 120i can also communicate through the interface protocol between network devices. In this case, relative to 110a, 120i is also a network device. Therefore, network devices and terminal devices can be collectively referred to as communication devices. Figure 2110a and 110b in the figure can be called communication devices with network device functions. Figure 2 120a-120j in the figure can be called communication devices with terminal equipment functions.

[0090] Network devices and terminal devices, network devices and network devices, and terminal devices and terminal devices can communicate through licensed spectrum, through unlicensed spectrum, or through both licensed spectrum and unlicensed spectrum at the same time, without limitation.

[0091] The transmitting device in the embodiment of the present application refers to the transmitting end of the sensing signal or the communication signal, and the receiving device refers to the receiving end of the echo signal of the sensing signal or the communication signal. It can be understood that the roles of the transmitting device and the receiving device can be interchangeable, that is, the transmitting device also has the receiving capability, and the receiving device also has the transmitting capability. For example, the transmitting device can be Figure 2 The network device in the receiver can be Figure 2 Alternatively, the sending device may be Figure 2 The terminal device in the Figure 2 The network device in; or, the sending device and the receiving device are Figure 2 The network device in; or, the sending device and the receiving device are Figure 2 There is no restriction on the terminal devices in the system.

[0092] Next, the technical features involved in the embodiments of the present application are introduced.

[0093] Perception technology can generally be divided into two types based on the mode: single-station perception and dual-station perception.

[0094] Among them, the single-station sensing mode means that the transmitter device of the sensing signal and the receiver device of the echo signal of the sensing signal are the same device. In other words, in the single-station sensing mode, the transmitter device must both send the sensing signal and receive the echo signal reflected by the sensing signal on the target surface. Therefore, the single-station sensing mode can also be called the self-transmitting and self-receiving mode without limitation.

[0095] The dual-station sensing mode means that the transmitter device of the sensing signal and the receiver device of the echo signal of the sensing signal are two different devices. In other words, sensing station A sends the sensing signal, and the echo signal reflected by the sensing signal on the target surface is received by sensing station B. Therefore, the dual-station sensing mode can also be called A send B receive mode.

[0096] Figure 3 A schematic diagram of a perception scenario applicable to an embodiment of the present application is provided. Figure 3Six sensing scenarios are provided, which are the scenarios where network device A sends and receives data by itself, such as Figure 3 As shown in (1) in the figure; the scenario where the terminal device A sends and receives data by itself, such as Figure 3 As shown in (2) in FIG. 1 ; a scenario in which network device A sends a sensing signal and network device B receives an echo signal, such as Figure 3 As shown in (3) in FIG. 1 ; a scenario in which terminal device A sends a sensing signal and terminal device B receives an echo signal, such as Figure 3 As shown in (4) in FIG. 1 ; a scenario in which network device A sends a sensing signal and terminal device A receives an echo signal, such as Figure 3 As shown in (5) in the figure; the scenario where the terminal device A sends a sensing signal and the network device A receives an echo signal, such as Figure 3 The embodiment of the present application focuses on two scenarios: a scenario where network device A sends a perception signal and network device B receives an echo signal, and a scenario where network device A sends a perception signal and a terminal device receives an echo signal.

[0097] It should be pointed out that Figure 3 The sensing target is a vehicle as an example, but the embodiments of the present application are not limited to this. For example, the sensing target can also be a pedestrian, a low-altitude drone, or other moving or stationary objects. Figure 3 The terminal device is taken as a smart phone as an example, but the embodiments of the present application are not limited to this.

[0098] In a wireless communication system, communications can be divided into different types according to the types of sending nodes and receiving nodes. Usually, sending information from a network device to a terminal device is called downlink communication, and sending information from a terminal device to a network device is called uplink communication. In the Long Term Evolution (LTE) / Long Term Evolution Advanced (LTE-A) communication system and the New RAT (NR) system, communications can be mainly divided into Frequency Division Duplex (FDD) mode and Time Division Duplex (TDD) mode according to the different duplex modes. For a wireless communication system operating in TDD mode, the downlink carrier and uplink carrier of the system are carriers of the same carrier frequency. The multiple access method usually adopts the Orthogonal Frequency Division Multiplexing Access (OFDMA) method. The main feature of OFDMA is that the transmission resources are divided into mutually orthogonal time-frequency resource elements (REs). The signals sent by the transmitter are carried on REs and transmitted to the receiver. Since different REs are orthogonal to each other, the receiver can receive the signals sent on each RE separately.

[0099] Figure 4 FIG. 1 is a flow chart of a communication method provided by an embodiment of the present application. Figure 4 As shown, the method may include the following contents.

[0100] S401. The first network device may determine a first time segment, a second time segment, and a third time segment, wherein the first time segment and the second time segment are respectively time segments occupied in a first time period, and the third time segment includes at least a portion of each second time segment in a plurality of the first time periods.

[0101] Optionally, the first time period may be a specific time period, such as 1ms, 0.5ms, 0.25ms, etc.; or it may be a predefined time unit. The predefined time unit may be agreed upon by the protocol or preconfigured, and the present application does not limit this. Exemplarily, it may be one or more symbols, or one or more time slots, or one or more mini-slots, or one or more subframes, or one or more frames, etc. The embodiments of the present application do not limit the time domain granularity. Taking 5G NR as an example, a time slot includes 14 symbols, so the first time period may be a time slot including 14 symbols. In subsequent standards, the same concepts as 4G and 5G may continue to be used, or newly named time units may be used.

[0102] Implementation method 1: The first time segment and the second time segment respectively occupy continuous time segments in the first time period. For example, when the first time period is 1ms, the first time segment may be the first 0.5ms of the 1ms, and the second time segment may be the last 0.5ms of the 1ms; generally, the first time segment is t ms in the 1ms, and the second time segment is 1-t ms in the 1ms. For another example, when the first time period includes 14 symbols, the first time segment may occupy the first M symbols of the 14 symbols, and the second time segment occupies the last 14-M symbols of the 14 symbols. Optionally, the first time segment may also be the last M symbols of the first time period, and the second time segment may be the first 14-M symbols of the first time period, which is not limited here.

[0103] Implementation method two, the first time segment and the second time segment respectively occupy discontinuous time segments in the first time period. For example, when the first time period is 1ms, the first time segment may be the first 0.4ms of the 1ms, and the second time segment may be the last 0.4ms of the 1ms; generally, the first time segment is t1ms in the 1ms, and the second time segment is t2ms in the 1ms, and t1+t2<1. For another example, when the first time period includes 14 symbols, the first time segment may occupy the first M1 symbols of the 14 symbols, and the second time segment occupies the last M2 symbols of the 14 symbols, and M1+M2<14. Optionally, the first time segment may also be the last M2 symbols of the first time period, and the second time segment may be the first M1 symbols of the first time period, and M1+M2<14, which is not limited here.

[0104] Furthermore, the wireless frame may include multiple first time periods, and each first time period may be configured to include both the first time segment and the second time segment; optionally, it may also be configured that some first time periods only include the first time segment, and some time periods may include both the first time segment and the second time segment. Generally speaking, the number of second time segments included in multiple first time periods is at least 2.

[0105] Optionally, when the second time segment is a time unit, the third time segment may include at least one time unit in each second time segment, and each third time segment may include K time units. For example, the time unit may be a symbol or multiple symbols, or other types of time units. Considering that the first time segment and the second time segment respectively occupy a part of the symbols of a time slot, the first time segment and the second time segment may be referred to as a time slot part (Slot Part, SP).

[0106] The frame structure for setting communication and perception multiplexing includes two time slot parts. The signal scheduled in the first time slot part only occupies the symbol of one time slot, and the signal scheduled in the second time slot part needs to occupy the symbols in multiple time slots, thereby achieving high perception efficiency.

[0107] The third time segment includes at least part of each of the second time segments in the plurality of the first time segments, and generally includes at least two second time segments, that is, the third time segment includes a part of each of at least two second time segments. Figure 6 As shown, there are a total of 3 first time periods, 3 first time segments, 3 second time segments and 2 third time segments, wherein each first time period includes 14 symbols, each first time segment includes 12 symbols, each second time segment includes 2 symbols, and each third time segment includes 3 symbols of the 3 second time segments.

[0108] In implementation mode 1, the time unit may be a symbol, the first time segment includes a part of the symbol, the second time segment includes a part of the symbol, and the plurality of first time segments includes a total of M2 second time segments. Figure 7 As shown, when the second time segment includes 7 symbols, the 3 second time segments may include 7 third time segments, wherein the 1st third time segment is composed of the 1st symbol of each of the 3 second time segments, the 2nd third time segment is composed of the 2nd symbol of each of the 3 second time segments, and so on.

[0109] In implementation mode 2, the time unit may be a plurality of symbols, the first time segment includes a portion of symbols, the second time segment includes a portion of symbols, and the plurality of first time segments includes a total of three second time segments. Figure 8 As shown, when the second time segment includes 8 symbols, 3 second time segments may include 4 third time segments, wherein the 1st third time segment is composed of the 1st-2nd symbols of each of the 3 second time segments, the 2nd third time segment is composed of the 3rd-4th symbols of each of the 3 second time segments, and so on.

[0110] Implementation method three, when the second time segment is a specific time segment, the third time segment includes K partial time segments. For example, the specific time segment of the second time segment can be 0.7s, which can be divided into 7 more specific time segments, each of which is 0.1s, then M2 second time segments can contain 7 third time segments, where the first third time segment is composed of the first 0.1s of each second time segment in the M2 second time segments, the second third time segment is composed of the second 0.1s of each second time segment in the M2 second time segments, and so on.

[0111] In implementation mode 4, the time units or specific time segments extracted (selected) from the second time segment each time may be continuous or discontinuous. Fig. 9 As shown, when the second time segment includes 7 symbols, the 3 second time segments may include 4 third time segments, wherein the 1st third time segment is composed of the 1st symbol of each of the 3 second time segments, the 2nd third time segment is composed of the 3rd symbol of each of the 3 second time segments, and so on, that is, extraction is performed at odd symbol positions.

[0112] In implementation mode 5, the positions of the time units or specific time segments extracted (selected) from the second time segment each time may correspond or may not correspond. Fig.10 As shown, when the second time segment includes 7 symbols, the three second time segments may include 6 third time segments, wherein the first time segment is composed of the first symbol of the first and second second time segments and the second symbol of the third second time segment among the three second time segments, the second time segment is composed of the second symbol of the first and second second time segments and the third symbol of the third second time segment, and so on.

[0113] Therefore, the number, position, and corresponding relationship of the time units or specific time segments of each second time segment included in the third time segment can be implemented in a variety of ways, which are not limited here. It can be seen that the implementation methods of the first time segment, the second time segment, and the third time segment are flexible and can be applied to different communication or perception scenarios.

[0114] S402. The first network device sends first indication information to the terminal device, wherein the first indication information indicates information of a first time segment, a second time segment, and a third time segment.

[0115] Correspondingly, the terminal device receives the first indication information sent from the first network device.

[0116] Optionally, the first indication information indicates the number of time units or the absolute time length contained in the first time segment, the number of symbols or the absolute time length contained in the second time segment, and the number of time units or the absolute time length occupied by the third time segment. Specifically, the first indication information may include three fields. When the first time period is a specific time period, the first indication information indicates the absolute time length contained in the first time segment, the absolute time length contained in the second time segment, and the absolute time length contained in the third time segment. When the first time period is a predefined time unit, the first indication information indicates the number of time units contained in the first time segment, the number of time units contained in the second time segment, and the number of time units contained in the third time segment. For example, the first field indicates the number of symbols in the first time segment, the second field indicates the number of symbols in the second time segment, and the third field indicates the number of symbols contained in the third time segment.

[0117] Optionally, the first indication information indicates the number of time units or the absolute time length contained in the first time segment, the number of symbols or the absolute time length contained in the second time segment, and / or the number of time units occupied by the third time segment. Specifically, the rule for the third time segment to select a time segment from the second time segment can be predefined, for example, the third time segment can be predefined as extracting (selecting) each time segment in each second time segment one by one. The first indication information may include 3 fields. When the first time period is a specific time period, the first indication information indicates the absolute time length contained in the first time segment, the absolute time length contained in the second time segment, and the third time segment can be reserved or can also indicate the extraction rule; when the first time period is a predefined time unit, the first indication information indicates the number of time units contained in the first time segment, the number of time units contained in the second time segment, and / or the number of time units occupied by the third time segment or can also indicate the extraction rule.

[0118] Further, the first indication information may indicate the position of the time unit contained in the first time segment, the position of the time unit contained in the second time segment, and / or the position of the time unit occupied by the third time segment. Specifically, the first indication information may include three fields, the first field indicates the symbol position of the first time segment, the second field indicates the symbol position of the second time segment, and the third field indicates the symbol position contained in the third time segment.

[0119] Furthermore, considering that not all first time periods contain the second time segment, e.g. Fig.11 As shown, the second first time period does not include the second time segment, so the first indication information may also include a field indicating the first time period including the second time segment. For example, the first indication information includes a fourth field, and the fourth field indicates the period and offset of the first time period including the second time segment. If the period of the first time period is 2, 4 or other values, it can be understood that there is a first time period including the second time segment for every 2 or every 4 first time periods; when the period is 2, the offset can be 0 or 1, where 0 indicates that the first time period with an even number includes the second time segment, and 1 indicates that the first time period with an odd number includes the second time segment, and of course it can also be the other way around.

[0120] Optionally, the first indication information may be carried in broadcast information and sent by the base station to the terminal, or may be carried in a system information block (SIB) or carried in radio resource control RRC layer signaling.

[0121] S403. The first network device sends second indication information to the terminal device, wherein the second indication information indicates that the first signal occupies the first time segment or the second time segment.

[0122] Correspondingly, the terminal device receives the second indication information sent from the first network device.

[0123] Furthermore, the second indication information instructs the first network device to send a first signal to the terminal device, or instructs the terminal device to send a first signal to the first network device.

[0124] Specifically, the second indication information includes a fifth field, which may be 1 bit, and state 0 indicates that the first signal occupies the first time segment, and state 1 indicates that the first signal occupies the second time segment; or state 1 indicates that the first signal occupies the first time segment, and state 0 indicates that the first signal occupies the second time segment.

[0125] Furthermore, the second indication information also includes a sixth field. When the fifth field indicates that the first signal occupies the first time segment, the sixth field indicates the position of the time unit in the first time segment occupied by the first signal; when the fifth field indicates that the first signal occupies the second time segment, the fifth field indicates the position of the time unit contained in the third time segment in the second time segment occupied by the first signal.

[0126] Furthermore, when the time unit is a symbol, when the fifth field indicates that the first signal occupies the first time segment, the sixth field indicates the symbol position in the first time segment occupied by the first signal; when the fifth field indicates that the first signal occupies the second time segment, the fifth field indicates the symbol position contained in the third time segment in the second time segment occupied by the first signal.

[0127] For example, the sixth field may contain 4 bits for a total of 16 states. When indicating the symbol position in the first time segment, there may be 16 states, and when indicating the symbol position in the second time segment, there may be less than 16 states, such as 12 states, 8 states, etc. That is, the number of bits of the fifth field depends on the larger number of states in the two cases.

[0128] Table 1 Sixth field design example

[0129]

[0130]

[0131] If the first time segment contains 10 symbols and the second time segment contains 4 symbols, the sixth field may contain 4 bits, which may indicate a total of 16 states. If the symbol position of the first time segment occupied by the first signal is indicated, a design method is shown in Table 1. If the symbol position of the second time segment occupied by the first signal is indicated, it may correspond to the previous four states. It should be noted that each state may correspond to the position of one or more symbols used, and there may be other defined methods other than those in the table, which are not limited here.

[0132] Optionally, the second indication information carries downlink control information (Downlink Control Information, DCI), which is sent by the network device to the terminal device.

[0133] Furthermore, the first signal may be used for sensing and / or communication, but is not limited thereto.

[0134] S404: The first network device sends a first signal to the terminal device, or the first network device receives a first signal from the terminal device.

[0135] The frame structure of communication and perception multiplexing includes multiple first time periods, and one first time period may include a first time segment and a second time segment. At least a part of the second time segments in the multiple first time periods is extracted (selected) to form a third time segment, so that the signal scheduled in the first time segment only occupies a time segment in the first time segment, and the signal scheduled in the second time segment can occupy multiple time segments in the first time segment because it can be indicated using the third time segment. Therefore, the signal scheduled by the first network device or the second network device in multiple second time segments can schedule more resources at the same time, thereby improving the scheduling efficiency.

[0136] The frame structure of communication and perception multiplexing will be able to achieve the optimal compromise between communication performance and perception performance, improve the efficiency of scheduling communication signals or perception signals, and for perception signals, be able to perceive targets at higher speeds, thereby improving perception capabilities.

[0159] In a possible implementation, the processing module 1201 may be used to determine a first time segment, a second time segment, and a third time segment.

[0160] It should be understood that a more detailed description of each module executing the corresponding process can be directly referred to Figures 4 to 5 The relevant description in any of the method embodiments shown in is directly obtained and will not be repeated here for the sake of brevity.

[0161] like Fig.13As shown, an embodiment of the present application provides a schematic diagram of the structure of a communication device 1300. The communication device 1300 may include a processor 1320, which is used to implement or support the communication device 1300 to implement the functions of the first communication device or the second communication device in any method embodiment of the present application. For details, please refer to the detailed description in the aforementioned method embodiment, which will not be repeated here. For example, the processor 1320 is used to read and execute program instructions through a communication interface so that the communication device 1300 implements the corresponding method. The processor 1320 may include one or more processors without limitation.

[0162] Specifically, the communication device 1300 can be a first communication device or a functional module located in the first communication device, which can implement the function of the first communication device in any method embodiment of the present application; or, the communication device 1300 can be a second communication device or a functional module located in the second communication device, which can implement the function of the second communication device in any method embodiment of the present application.

[0163] It should be pointed out that the above-mentioned functional modules can be implemented by hardware or by a combination of hardware and software without limitation.

[0164] For example, the communication device 1300 may be a chip system, wherein the chip system may be composed of a chip, or may include a chip and other discrete devices, without limitation.

[0165] Optionally, the communication device 1300 may further include a memory 1330 for storing program instructions and / or data. The memory 1330 is coupled to the processor 1320. The coupling may be understood as an indirect coupling or communication connection between devices, units or modules, which may be electrical, mechanical or other forms, for information exchange between devices, units or modules.

[0166] Furthermore, the processor 1320 is configured to execute program instructions stored in the memory 1330 so that the communication device 1000 implements a corresponding method.

[0167] Among them, one or more memories in the memory 1330 may be included in the processor, and the memory 1330 may also exist independently, such as an off-chip memory, through a communication bus ( Fig.13 The memory 1330 and the processor 1320 may also be integrated together.

Exemplarily, when the communication device is a first communication device, the other device can be a second communication device, etc. The processor 1320 can use the communication interface 1310 to send and receive data.
