[0062] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that 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 unless otherwise specifically stated.

[0063] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0064] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0065] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0066] 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.

[0067] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0068] At present, mobile communication networks only have limited positioning capabilities for active devices, and do not have the ability to perceive general targets in the environment. As a key technology of 6G networks, synaesthesia integration is gradually moving from technical research to commercial implementation and standardization. In order to enable existing communication systems to have perception capabilities, it is necessary to allocate perception resources at the physical layer. Therefore, the existing communication frame structure needs to be redesigned to meet perception needs. How to achieve synaesthesia integration at the frame structure level (physical layer) is a problem that needs to be solved.

[0069] In response to the above problems, the present disclosure proposes a communication method, in which a user device receives a signal carried by a wireless frame sent by a network device, and the signal includes a communication signal and a perception signal. The wireless frame includes communication resources and perception resources, wherein the communication resources are used to carry the communication signal, and the perception resources are used to carry the perception signal. A frame format suitable for a communication and perception integrated system is provided to support the perception capability expansion of the wireless communication system, and synaesthesia integration is realized at the frame structure level, as follows.

[0070] Figure 1 A flow chart showing some embodiments of the communication method of the present disclosure.

[0071] like Figure 1 As shown, the communication method includes step 110, which is executed by the user equipment.

[0072] In step 110, a signal carried by a wireless frame sent by a network device is received, wherein the signal includes a communication signal and a perception signal, the wireless frame includes a communication resource and a perception resource, the communication resource is used to carry the communication signal, and the perception resource is used to carry the perception signal.

[0073] In some embodiments, the communication signal refers to other communication signals except the perception signal. That is, the communication signal is used for communication services, and the perception signal is used for perception services.

[0074] For example, the sensing resource includes at least one of a half-duplex mode sensing symbol and a full-duplex mode sensing symbol.

[0075] A half-duplex mode sensing symbol includes four time periods: sending a sensing signal, switching between sending and receiving, receiving a sensing signal, and switching between receiving and sending.

[0076] The main features of half-duplex mode are full-array transmission and reception, and a short waveform duration. The advantage is that it can send signals at high power and has full-array gain, so the perception distance is long. The disadvantage is that signals cannot be received in the first two time periods, so there is a perception blind spot.

[0077] That is to say, if the perception resources include half-duplex mode perception symbols, synaesthesia integration at a longer perception distance can be achieved, but there will be perception blind spots.

[0078] The sending and receiving of the sensing signal are performed simultaneously within one full-duplex mode sensing symbol.

[0079] The main feature of full-duplex mode is that part of the array transmits and part of the array receives, and the waveform duration is longer. The advantage is that there is no perception blind area. The disadvantage is that the transmit-receive isolation requires limiting the signal transmission power, and there is only partial array gain, so the perception distance is shorter.

[0080] That is to say, if the sensing resources include full-duplex mode sensing symbols, sensing blind spots can be achieved, but the transmit-receive isolation requires limiting the signal transmission power. In addition, since there is only partial array gain, the sensing distance is short.

[0081] In some embodiments, the radio frame includes a first type of period containing communication resources and sensing resources and a second type of period containing only communication resources, wherein the communication resources include at least one of uplink communication resources and downlink communication resources. The communication resources include communication time slots and communication symbols.

[0082] In some embodiments, the first type of cycle includes a sensing time slot, and the sensing time slot is located between a downlink time slot and a special time slot of the downlink communication resource.

[0083] By configuring a small number of first-class cycles containing perception resources in the wireless frame, flexible adjustment of perception resource overhead is achieved, and each cycle includes uplink communication resources and downlink communication resources, which ensures the continuity of communication services and the quality of integrated communication.

[0084] In addition, the present disclosure is based on the existing communication frame structure, and by modifying part of the cycle in the wireless frame, continuous perception resources are configured after the original downlink communication symbol and before the uplink communication symbol, thereby supporting flexible and adjustable synaesthesia resource ratio.

[0085] For example, a wireless frame includes K cycles, each cycle has the same time length, and within the wireless frame, the number of first-type cycles containing communication resources and sensing resources is M, and the number of second-type cycles containing only communication resources is KM.

[0086] If a radio frame includes multiple first-type periods, the multiple first-type periods may be configured continuously or discontinuously in the radio frame.

[0087] In the case where multiple first-type periods are configured non-continuously, the multiple first-type periods may be configured at equal intervals or at unequal intervals.

[0088] In some embodiments, for different first-type periods within a wireless frame, the types of sensing symbols (e.g., half-duplex mode sensing symbols, full-duplex mode sensing symbols, half-duplex mode sensing symbols, and full-duplex mode sensing symbols) may be the same or may be the same.

[0089] In some embodiments, if the first type of cycle includes a special time slot, the sensing resource is configured in the special time slot, and the sensing resource starts from the last downlink communication symbol in the special time slot and occupies a plurality of consecutive downlink communication symbols in the forward direction.

[0090] That is to say, priority is given to occupying the downlink communication symbols at the end of the first cycle, and the number of sensing resources is configured from the end to the beginning.

[0091] Through forward occupation, it is convenient to give priority to the use of scattered downlink communication symbol resources in special time slots. Taking into account that in each time slot, the first few (usually 2 or 3) symbols are generally PDCCH (Physical Downlink Control Channel), so if it is occupied from front to back, there may be a risk that the first few symbols will be configured as perception symbols. At this time, although the last few symbols of the time slot are communication symbols, due to the lack of PDCCH, there will be a risk of being unable to schedule and utilize them. Therefore, through forward occupation, the quality of communication is guaranteed during the communication integration process.

[0092] By preferentially allocating scattered downlink communication resources in special time slots for sensing, it is beneficial to maintain the integrity of the communication time slot and also beneficial to the resource scheduling of the communication system.

[0093] In some embodiments, if the first type of cycle does not include a special time slot, the sensing resource starts from the last downlink communication symbol in the downlink communication resource and occupies a plurality of consecutive downlink communication symbols in the forward direction.

[0094] It should be noted that the total duration of multiple downlink communication symbols occupied in the forward direction is the same as the total duration of the sensing resources.

[0095] Because the received signal is carried by the radio frame sent by the network device, that is, the network device senses and sends the sensed signal to the user device, the sensing resource occupies the downlink communication symbol. If the signal carried by the radio frame is sent by the user device, that is, the user device senses and sends the sensed signal to the network device, the sensing resource needs to occupy the uplink communication symbol in the communication resource.

[0096] For example, in a first-type period, when the number of downlink communication symbols occupied by the sensing resource is L, there are the following three situations:

[0097] If the sensing resource is m consecutive P symbols, m×x=L is satisfied, where the duration of the P symbol may be x times the duration of each communication symbol.

[0098] If the sensing resource is n consecutive C symbols, n×y=L is satisfied, wherein the duration of the C symbol may be y times the duration of each communication symbol.

[0099] If the sensing resources are m consecutive P symbols and n consecutive C symbols, m×x+n×y=L is satisfied.

[0100] By flexibly configuring the number of perception symbols, flexible control of perception overhead is achieved, which can be configured according to perception requirements, thereby improving the flexibility of synaesthesia integration.

[0101] In some embodiments, the duration of the perception symbol in the perception resource is the same as or different from the duration of the communication symbol in the communication resource, and the duration of the perception symbol is the same as or different from the duration of other perception symbols.

[0102] When the subcarrier spacing is small, the duration of each communication symbol is longer, and the duration of the perceived symbol may be shorter than the duration of the communication symbol; when the subcarrier spacing is large, the duration of each communication symbol is short, and the duration of the perceived symbol may be longer than the duration of the communication symbol.

[0103] For example, the duration of a half-duplex mode perception symbol may be x times the duration of each communication symbol, where x is greater than or equal to 0, and the duration of a full-duplex mode perception symbol may be y times the duration of each communication symbol, where y is greater than or equal to 0.

[0104] By flexibly adjusting the number of perception symbols, the duration of perception resources can be flexibly adjusted to flexibly adapt to the perception coverage and accuracy requirements. By flexibly configuring the duration of perception symbols, flexible control of perception overhead is achieved, which can be configured according to perception requirements, improving the flexibility of synaesthesia integration.

[0105] In some embodiments, the communication resources include downlink communication symbols, the perception resources include perception symbols, and zero, one or more guard interval symbols are set between the last downlink communication symbol and the first perception symbol in the first type period.

[0106] In some embodiments, the communication resources include uplink communication symbols, the sensing resources include sensing symbols, and zero, one or more guard interval symbols are set between the last sensing symbol and the first uplink communication symbol in the first type period.

[0107] By setting a guard interval symbol between the last downlink communication symbol and the first perception symbol in the first type of period, and between the last perception symbol and the first uplink communication symbol in the first type of period, the success rate of the switching of the antenna and related RF devices in hardware is guaranteed, and the risk of interference with perception caused by the last downlink communication symbol or the first uplink communication symbol is reduced. In addition, if the guard interval symbol is not configured, the signal propagated in the previous communication symbol will remain in the next perception symbol. This risk can be reduced by the guard interval symbol.

[0108] The present disclosure provides a frame structure with relatively minor changes compared to the existing frame structure, has good protocol backward compatibility, and ensures the feasibility of realizing synaesthesia integration at the frame structure level.

[0109] Figure 2 Schematic diagrams showing some embodiments of radio frames of the present disclosure.

[0110] like Figure 2 As shown, the wireless frame 21 includes one or more first-type periods 22 and one or more second-type periods 23, wherein the first-type period 22 includes downlink communication resources (D), protection interval symbols (G), perception resources (R) and uplink communication resources (U), and the second-type conversion period 23 includes downlink communication resources (D), protection interval symbols (G) and uplink communication resources (U).

[0111] In addition, the sensing resources (R) in the first type of period 22 include a plurality of half-duplex mode sensing symbols (P) 24. The downlink communication resources (D) include a plurality of downlink communication symbols, and the uplink communication resources (U) include a plurality of uplink communication symbols.

[0112] Figure 3 Schematic diagrams showing other embodiments of the radio frame of the present disclosure.

[0113] like Figure 3As shown, the wireless frame 31 includes one or more first-type periods 32 and one or more second-type periods 33, wherein the first-type period 32 includes downlink communication resources (D), protection interval symbols (G), perception resources (R) and uplink communication resources (U), and the second-type conversion period 33 includes downlink communication resources (D), protection interval symbols (G) and uplink communication resources (U).

[0114] In addition, the sensing resources (R) in the first type of period 32 include a plurality of full-duplex mode sensing symbols (C) 34. The downlink communication resources (D) include a plurality of downlink communication symbols, and the uplink communication resources (U) include a plurality of uplink communication symbols.

[0115] In order to meet the kilometer-level continuous sensing coverage, half-duplex mode sensing symbols and full-duplex mode sensing symbols need to cooperate to be responsible for long-distance coverage and short-distance blind spot filling respectively. In other words, the sensing resources include half-duplex mode sensing symbols and full-duplex mode sensing symbols.

[0116] By supporting the configuration of sensing symbols for both full-duplex and half-duplex modes through sensing resources, short-distance sensing and long-distance coverage are achieved respectively.

[0117] Due to the different characteristics and goals of the two modes, the corresponding sensing symbol lengths and quantities may also be different. Considering the limited beam width, omnidirectional beam scanning requires a lot of resources, so the performance indicators such as sensing overhead and accuracy coverage need to be weighed. These factors have posed challenges to the frame structure design. The frame structure of the wireless frame sent by the network device is as follows.

[0118] In some embodiments, when the sensing resources include half-duplex mode sensing symbols and full-duplex mode sensing symbols, in a first-type cycle, the half-duplex mode sensing symbols are continuously configured, and the full-duplex mode sensing symbols are continuously configured. In other words, the half-duplex mode sensing symbols and the full-duplex mode sensing symbols are respectively continuously configured without cross occupation, and the occupation order of the half-duplex mode sensing symbols and the full-duplex mode sensing symbols is not limited.

[0119] By continuously configuring half-duplex mode perception symbols and full-duplex mode perception symbols in a first-class cycle, it is convenient to perform directional beamforming on multiple consecutive same-type perception symbols in a single first-class cycle, realize beam scanning through multiple cycles, and achieve omnidirectional perception coverage in the spatial domain.

[0120] Considering that the conversion between half-duplex mode sensing symbols and full-duplex mode sensing symbols requires hardware switching time, half-duplex mode sensing symbols and full-duplex mode sensing symbols are configured continuously and do not cross-occupy. In addition, in order to sense, multiple symbols of the same wave in one beam direction need to be accumulated, otherwise the energy is insufficient, so multiple continuous symbols need to be configured.

[0121] Figure 4 Schematic diagrams showing still further embodiments of the radio frame of the present disclosure.

[0122] like Figure 4 As shown, the wireless frame 41 includes one or more first-type periods 42 and one or more second-type periods 43, wherein the first-type period 42 includes downlink communication resources (D), protection interval symbols (G), perception resources (R) and uplink communication resources (U), and the second-type conversion period 43 includes downlink communication resources (D), protection interval symbols (G) and uplink communication resources (U).

[0123] In addition, the sensing resources (R) in the first type period 42 include multiple half-duplex mode sensing symbols (P) 44 and multiple full-duplex mode sensing symbols (C) 45, wherein the multiple half-duplex mode sensing symbols 44 precede the multiple full-duplex mode sensing symbols 45. The downlink communication resources (D) include multiple downlink communication symbols, and the uplink communication resources (U) include multiple uplink communication symbols.

[0124] Figure 5 Schematic diagrams showing still further embodiments of the radio frame of the present disclosure.

[0125] like Figure 5 As shown, the wireless frame 51 includes one or more first-type periods 52 and one or more second-type periods 53, wherein the first-type period 52 includes downlink communication resources (D), protection interval symbols (G), perception resources (R) and uplink communication resources (U), and the second-type conversion period 53 includes downlink communication resources (D), protection interval symbols (G) and uplink communication resources (U).

[0126] In addition, the sensing resources (R) in the first type of period 52 include multiple half-duplex mode sensing symbols (P) 54 and multiple full-duplex mode sensing symbols (C) 55, wherein the multiple half-duplex mode sensing symbols 54 are after the multiple full-duplex mode sensing symbols 55. Among them, the downlink communication resources (D) include multiple downlink communication symbols, and the uplink communication resources (U) include multiple uplink communication symbols.

[0127] By supporting the configuration of sensing resources as half-duplex mode sensing symbols and / or full-duplex mode sensing symbols, the sensing coverage and accuracy requirements can be flexibly adapted.

[0128] Through half-duplex mode sensing symbols and full-duplex mode sensing symbols, where half-duplex mode sensing symbols are used for large-range and long-distance sensing, and full-duplex mode sensing symbols are mainly used for short-distance blind spot filling, the two can work together to achieve continuous sensing coverage.

[0129] In some embodiments, the sensing signal carried in the half-duplex mode sensing symbol and the full-duplex mode sensing symbol adopts a linear frequency modulation waveform.

[0130] For example, the bandwidth and duration of a linear frequency modulation waveform are determined based on perceptual needs.

[0131] For example, the linear frequency modulation waveform used by the perception signal carried in the full-duplex mode perception symbol includes an OFDM (Orthogonal Frequency Division Multiplexing) waveform, and the transmission sequence of the linear frequency modulation waveform includes at least one of a Zadoff-Chu sequence and a Gold sequence.

[0132] In some embodiments, the transmitted sequence of the linear frequency modulation waveform is a sequence with good autocorrelation and cross-correlation.

[0133] The linear frequency modulation waveform used for the sensing signal carried in the half-duplex mode sensing symbol is as shown in formula (1).

[0134]

[0135] When the linear frequency modulation waveform is transmitted, it needs to be modulated to a suitable carrier frequency f 0 , the waveform sent by the radar is shown in formula (2), where the carrier frequency can be determined by the operator.

[0136] x p (t) = exp(j2πf 0 t)s p (t) (2)

[0137] Where τ is the pulse width, B p is the pulse wave sensing signal bandwidth. The minimum value of the pulse width τ satisfies the hardware capability, so that the signal frequency can be linearly changed within the τ time. p , the maximum value of the pulse width τ satisfies the predetermined maximum sensing distance R p max , as shown in formula (3).
