For the field of vehicle-to-everything (V2X), waveform technology based on cellular and vehicle-to-vehicle communication can improve communication reliability and bandwidth transmission rate.

[0044] Next, the technical solutions in the embodiments of the present application will be clearly described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0045] The terms "first", "second", etc. in the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "or" in the present application means at least one of the connected objects. For example, "A or B" covers three scenarios, namely, Scenario 1: including A and not including B; Scenario 2: including B and not including A; Scenario 3: including both A and B. The character " / " generally indicates an "or" relationship between the associated objects before and after.

[0046] The term "indicate" in the present application can be either a direct indication (or an explicit indication) or an indirect indication (or an implicit indication). Among them, a direct indication can be understood as that the sender clearly tells the receiver specific information, operations to be performed, request results, etc. in the sent indication; an indirect indication can be understood as that the receiver determines the corresponding information according to the indication sent by the sender, or makes a judgment and determines the operations to be performed or request results, etc. according to the judgment result.

[0047] Spectrum resources play a key role in the development of wireless communications. Whether it is communication quality, communication rate or communication stability, they are closely related to the use of spectrum resources. With the continuous advancement and innovation of radio technology, various new radio services are constantly emerging, and the contradiction between supply and demand of spectrum resources is becoming more and more obvious. Compared with high frequency bands, medium and low frequency bands have better signal penetration, can provide wider wireless coverage and more stable communication experience, and reduce the deployment cost of operators. However, the tension of spectrum resources in medium and low frequency bands is also significant. This is mainly because spectrum resources are limited to a certain extent. In addition, due to the problem of discontinuous spectrum resources, there are great differences in spectrum resources in medium and low frequency bands between different countries.

[0048] The supply and allocation of spectrum resources has led to an intensification of the contradiction between spectrum supply and demand. For example, in some countries, high-quality mid-band spectrum has been allocated to other places, resulting in the shortage of spectrum resources in the fifth generation (5G) th In the deployment of 5G (Next Generation, 5G) networks, operators' spectrum resources are mainly concentrated on high-frequency millimeter waves, which has exacerbated the tension of spectrum resources. At the same time, the high cost of spectrum acquisition has also become one of the more prominent problems for wireless communication companies. Overseas, many operators have spent a lot of money to obtain 3G, 4G, and 5G spectrum resources, which has brought huge development pressure. The high cost of spectrum acquisition and insufficient spectrum resource supply are both great challenges for wireless communication companies. How to further improve the use and utilization efficiency of spectrum resources based on relevant technologies is a technical problem that needs to be solved.

[0049] In an embodiment of the present application, within a first time unit, symbols corresponding to the first waveform and symbols corresponding to the second waveform are transmitted respectively through the first frequency domain resources and the second frequency domain resources overlapping in the frequency domain. The first waveform and the second waveform perform time division multiplexing on the frequency domain resources within the first time unit. The solution provided by the embodiment of the present application is within the above-mentioned first time unit, for example, the length of a first time unit is one time slot, after the symbol corresponding to the first waveform is transmitted through the first frequency domain resource, if there is remaining time, the symbols corresponding to other waveforms (such as the second waveform) are also transmitted through the second frequency domain resource overlapping in the frequency domain with the first frequency domain resource. In addition, within the first time unit, a third waveform can also be transmitted through the above-mentioned frequency domain resources, and the third waveform is frequency-division multiplexed with at least one of the first waveform and the second waveform. Thus, the embodiment of the present application provides a solution for multiplexing the above-mentioned frequency domain resources within the first time unit, which realizes the improvement of the utilization rate of the frequency domain resources within a time unit and more effectively utilizes the spectrum resources; at the same time, the embodiment of the present application provides a solution that can flexibly switch different waveforms for transmission on the frequency domain resources overlapping in the frequency domain, which can improve the flexibility and adaptability of signal transmission and is conducive to meeting the needs of various transmission scenarios.

By respectively transmitting symbols corresponding to the first waveform and symbols corresponding to the second waveform through the first frequency-domain resource and the second frequency-domain resource that overlap in the frequency domain within the first time unit, a time-division multiplexing solution for the above-mentioned frequency-domain resources within the first time unit is provided, realizing an improvement in the utilization rate of the frequency-domain resources within one time unit, which is conducive to meeting the requirements of different services for frequency-domain resources.

[0056] The following will combine the accompanying drawings and describe in detail the method for sharing frequency-domain resources provided in the embodiments of this application through some embodiments and their application scenarios.

[0057] Figure 2 It is a schematic flowchart of the method P200 for sharing frequency-domain resources provided in Embodiment 1 of this application. The method P200 for sharing frequency-domain resources is applied to a signal sending device, which can be the network-side device 120 or the terminal device 110. As Figure 2 shown, the method P200 for sharing frequency-domain resources provided in this embodiment includes the following steps.

[0058] S210. Within the first time unit, transmit symbols corresponding to the first waveform through the first frequency-domain resource.

[0059] S220. Within the first time unit, transmit symbols corresponding to the second waveform through the second frequency-domain resource, where the first waveform and the second waveform are supported waveforms; wherein, the first frequency-domain resource and the second frequency-domain resource overlap in the frequency domain, and the first waveform and the second waveform perform time-division multiplexing on the frequency-domain resources within the first time unit.

[0060] In an exemplary embodiment, the lengths of different first time units can be equal. For example, the length of the first time unit is one time slot.

[0061] In an exemplary embodiment, within the above-mentioned first time unit, symbols corresponding to a first waveform are transmitted to the AIoT terminal device via a first frequency-domain resource X1. After receiving the symbols corresponding to the first waveform, the AIoT terminal may store energy and be in a state of not transmitting or receiving signals. If there is remaining time in the first time unit after transmitting the first waveform, in the embodiments of the present application, symbols corresponding to other waveforms may also be transmitted via a second frequency-domain resource X2 that is frequency-domain overlapped with the first frequency-domain resource. For example, symbols corresponding to a second waveform are sent to a certain vehicle networking terminal device. Thus, the embodiments of the present application provide a time-division multiplexing scheme for the above-mentioned frequency-domain resources within the first time unit, achieving an improvement in the utilization rate of frequency-domain resources within one time unit, and further facilitating the satisfaction of the frequency-domain resource requirements of different services.

[0062] In an exemplary embodiment, among the multiple waveforms for multiplexing the above-mentioned frequency-domain resources, in addition to the waveforms for time-division multiplexing, there is also a third waveform that is frequency-division multiplexed with the above-mentioned second waveform and first waveform. For example, within the above-mentioned first time unit, when the second waveform and the third waveform satisfy frequency-division multiplexing, the second waveform and the third waveform respectively transmit signals via different subsets of the above-mentioned second frequency-domain resource. For example, within the above-mentioned first time unit, when the first waveform and the third waveform satisfy frequency-division multiplexing, the first waveform and the third waveform respectively transmit signals via different subsets of the above-mentioned first frequency-domain resource. For another example, within the above-mentioned first time unit, when the third waveform respectively satisfies frequency-division multiplexing with the first waveform and the second waveform, the third waveform and the first waveform respectively transmit signals via different subsets of the above-mentioned first frequency-domain resource, and the third waveform and the second waveform respectively transmit signals via different subsets of the above-mentioned second frequency-domain resource. Thus, frequency-division multiplexing of the frequency-domain resources is achieved, which is conducive to further improving the utilization rate of frequency-domain resources.

[0063] In an exemplary embodiment, the first frequency-domain resource and the second frequency-domain resource overlap in the frequency domain. Specifically, the first frequency-domain resource and the second frequency-domain resource multiplexed within the above-mentioned first time unit may belong to high-frequency band frequency-domain resources, or the first frequency-domain resource and the second frequency-domain resource may also be medium and low-frequency band frequency-domain resources. Exemplarily, the multiplexed frequency-domain resource is any one partial bandwidth (Bandwidth Part, BWP). It can be understood that BWP is equivalent to dividing the 5G spectrum into many small blocks within a certain period of time. Each BWP can use different parameter sets, and its bandwidth, subcarrier spacing, and other control parameters can all be different, which is equivalent to dividing several sub-cells with different configurations within the 5G cell to adapt to different types of terminals and service types.

[0064] In an exemplary embodiment, the length of the first time unit may be determined according to the symbol length of a specific waveform. Wherein, the specific waveform refers to any waveform supported for transmission in the first frequency domain resource or the second frequency domain resource. Exemplarily, the length of the first time unit may also be determined according to the symbol length of other waveforms that are not supported for transmission through the first frequency domain resource or the second frequency domain resource temporarily, and the embodiments of the present application do not limit this. Exemplarily, the length of the first time unit may specifically be the symbol length of a waveform, or may also be the sum of the symbol lengths of multiple symbols of the same waveform. For example, the length of a first time unit may be the symbol length of an Orthogonal Frequency Division Multiplexing (OFDM), or may also be the sum of the symbol lengths of multiple OFDMs. Exemplarily, the length of the first time unit may also be determined according to the symbol lengths of other waveforms, such as the symbol length of Gaussian minimum shift keying (GMSK), the symbol length of On-Off Keying (OOK), the symbol length of Amplitude Shift Keying (ASK), the symbol length of Frequency Shift Keying (FSK), the symbol length of Phase Shift Keying (PSK), the symbol length of Orthogonal Time Frequency Space (OTFS), etc. Exemplarily, the length of a first time unit may also be the sum of the symbol lengths of different types. For example, the length of the first time unit is the sum of the symbol length of an OFDM and the symbol length of an OOK.

[0065] In an exemplary embodiment, the length of the first time unit may also be a fixed duration, such as 1 ms.

[0066] In an exemplary embodiment, the first time unit is a time slot (slot).

[0067] Exemplarily, regarding the method for determining the length of the above-mentioned first time unit, it can be defined by a communication protocol. Another exemplarily, regarding the method for determining the length of the above-mentioned first time unit, it can also be configured through semi-static signaling. For example, through radio resource control (RRC) semi-static configuration, during the multiplexing process of frequency domain resource A, the length of the first time unit is determined according to the symbol length of OFDM. Another exemplarily, regarding the method for determining the length of the above-mentioned first time unit, it can also be configured through dynamic signaling according to actual requirements. For example, using media access control (MAC) layer control element (CE) MAC CE signaling or L1 signaling for dynamic adjustment, during the multiplexing process of frequency domain resource A, the first time unit adopts a fixed duration a during the signal transmission in a certain time period, and the first time unit adopts a fixed duration b during the signal transmission in another time period, and MAC CE signaling or L1 signaling is used for indication.

[0068] In an exemplary embodiment, to facilitate the positioning of the transmission time of the above-mentioned time-division multiplexed waveform. The above-mentioned first time unit can be composed of multiple second time units. Exemplarily, the start time of the first symbol of each waveform for time-division multiplexing of the above-mentioned frequency domain resource is aligned with the start times of different second time units in the first time unit, so as to achieve the positioning of the waveform for time-division multiplexing.

[0069] In an exemplary embodiment, the length of the above-mentioned second time unit can be determined according to the symbol length of a specific waveform. Wherein, the above-mentioned specific waveform refers to any waveform supported for transmission in the above-mentioned first frequency domain resource or second frequency domain resource. Exemplarily, the length of the above-mentioned second time unit can also be determined according to the symbol length of other waveforms that are not supported for transmission temporarily through the above-mentioned first frequency domain resource or second frequency domain resource, and the embodiments of the present application do not limit this.

[0070] Exemplarily, the length of the above-mentioned second time unit can also be determined according to the symbol length of orthogonal frequency division multiplexing (OFDM). Exemplarily, the length of the second time unit can specifically be the symbol length of a waveform. As Figure 3A shown, the length of a second time unit 321 is the symbol length of one OFDM. Taking the reference subcarrier spacing of 15 KHz as an example, the length of one second time unit 321 is the symbol length of one OFDM, and one first time unit 311 is one slot. Figure 3AA first time unit 311 shown contains a plurality of second time units 312. Among them, the CP of the OFDM symbol numbered 0 and the cyclic prefix of the OFDM symbol numbered 7 are extended cyclic prefixes (ECPs), and the cyclic prefixes of OFDM symbols with other numbers are normal cyclic prefixes (NCPs). It can be seen that the lengths between different second time units can be the same or different. Specifically, in this embodiment, the length of the second time unit is calculated as shown in formula (1) below.

[0071]

[0072]

[0073]

[0074] where κ = 64, which is the ratio of the basic time unit in the LTE system to the basic time unit in the NR system. 5G NR will use the parameter μ to represent the carrier spacing. For example, μ = 0 represents the same carrier spacing as 15 kHz in the LTE system. The basic time unit Tc = 1 / (480 * 1000 * 4096) = 0.509 ns.

[0075] Exemplarily, the length of the second time unit can specifically also be the sum of the lengths of multiple symbols of the same waveform. As Figure 3B shown, the length of a second time unit 322 is the sum of the lengths of two OFDM symbols. It can be understood that the length of the above-mentioned second time unit can also be the sum of the lengths of 3 or more OFDM symbols, and this application embodiment does not limit this.

[0076] In an exemplary embodiment, the length of the above-mentioned second time unit can also be determined according to the symbol lengths of other waveforms, such as the symbol length of GMSK, the symbol length of OOK, the symbol length of ASK, the symbol length of FSK, the symbol length of PSK, the symbol length of OTFS, etc. Exemplarily, the length of a second time unit can also be the sum of the symbol lengths of different types. For example, the length of the second time unit is the sum of the symbol length of an OFDM symbol and the symbol length of an OOK.

[0077] In an exemplary embodiment, the length of the above-mentioned second time unit can take the value of: the symbol length of the target waveform (any one of the multiple waveforms) among the multiple waveforms transmitted within the first time unit. Thus, it is beneficial to align the target waveform with the boundary of the second time unit during the signal transmission process, and further facilitate the positioning of the transmission time of the transmitted signal.

[0078] In an exemplary embodiment, the length of the second time unit described above may also be a fixed duration. Exemplarily referring to Figure 3C , the duration of each second time unit is a fixed value. For example, the length of each second time unit is 0.1 ms.

[0079] Exemplarily, regarding the method for determining the length adopted by the second time unit described above, it can be defined by a communication protocol. Another exemplarily, regarding the method for determining the length adopted by the second time unit described above, it can also be configured by semi-static signaling. For example, through semi-static configuration of Radio Resource Control (RRC), during the multiplexing process of frequency domain resource A, the length of the second time unit is the symbol length of waveform a. Yet another exemplarily, regarding the method for determining the length adopted by the second time unit described above, it can also be configured by dynamic signaling. For example, using MAC CE signaling or L1 signaling for dynamic adjustment, during the multiplexing process of frequency domain resource A, during the signal transmission process in a certain time period, the second time unit adopts a fixed duration a, and during the signal transmission process in another time period, the second time unit adopts a fixed duration b, and MAC CE signaling or L1 signaling is used for indication.

[0080] Exemplarily, referring to Figure 3A , the first time unit 311 includes 14 second time units 321. Referring to Figure 3B , the first time unit 312 includes 7 second time units 322. Referring to Figure 3C , the first time unit 313 includes 10 second time units 323. Among them, the number of the second time units included in the first time unit can also be defined by a communication protocol. It can also be configured by semi-static signaling. For example, through semi-static configuration of RRC, during the multiplexing process of frequency domain resource A, each first time unit contains 10 second time units. It can also be configured by dynamic signaling. For example, using MAC CE signaling or L1 signaling for dynamic adjustment, during the multiplexing process of frequency domain resource A, during the signal transmission process in a certain time period, each first time unit contains 10 second time units, and during the signal transmission process in another time period, each first time unit contains 14 second time units, and MAC CE signaling or L1 signaling is used for indication.

[0081] In an exemplary embodiment, the above-mentioned multiple waveforms may include the following types: OFDM waveform, OOK waveform, ASK waveform, FSK waveform, PSK waveform, GMSK waveform, Frequency Modulated Continuous Wave (FMCW), etc. They may also be other types of waves, which are not limited in the embodiments of the present application. Among them, the waveforms that perform time-division multiplexing on the above frequency-domain resources may be different types of waveforms or the same type of waveforms, which are not limited in the embodiments of the present application. That is to say, in the embodiments provided in the present application, the scheme of flexibly switching different waveforms for transmission on overlapping frequency-domain resources can improve the flexibility and adaptability of signal transmission and is conducive to meeting the requirements of various transmission scenarios.

[0082] Exemplarily, in the first time unit, the symbols corresponding to the first waveform are transmitted first, and then the symbols corresponding to the second waveform are transmitted. For example, the frequency-domain resource BWP1 is mainly used for the transmission of services corresponding to the first waveform X1. When the transmission of services corresponding to the first waveform X1 is temporarily not required and within a first time unit, the transmission of services corresponding to the second waveform X2 can be performed through BWP2 that overlaps with BWP1 in the frequency domain. Among them, the first waveform X1 and the second waveform X2 perform time-division multiplexing on the frequency-domain resources.

[0083] In an exemplary embodiment, as a specific implementation manner of S210: the start time of the first symbol of the first waveform is aligned with the start time of a certain second time unit in the first time unit. For example, refer to Figure 4A - Figure 4E , the start time of the first symbol of the first waveform is aligned with the start time of the first second time unit in the first time unit to save frequency-domain resources. Exemplarily, refer to Figure 4A , for the symbol numbered 0 in the first waveform 411, its start time is aligned with the start time of the second time unit 321 numbered 0 in the first time unit 311. Exemplarily, if there are preset requirements for the transmission of symbols corresponding to the first waveform, for example, a duration x needs to be reserved before transmission. If the duration of x is less than the duration of the second time unit, then the first second time unit can be controlled to meet the above preset requirements, and the transmission of the symbols corresponding to the first waveform can start from the second second time unit.

[0084] In an exemplary embodiment, to ensure correct symbol intervals, avoid unexpected errors, and thus ensure the accuracy of system input and output, if after the transmission of the first waveform ends within the first time unit and the end time of the last symbol of the waveform is not aligned with the start time or end time of the second time unit, then within the first time period, 0 is transmitted, the cyclic suffix of the modulation symbols of the first waveform is transmitted, or the cyclic prefix of the modulation symbols of the second waveform is transmitted. Wherein, the first time period is the time period between the end time of the last symbol of the first waveform and the end time of the second time unit corresponding to the end time of the last symbol of the first waveform. Exemplarily, referring to Figure 4A , the number of the last symbol of the first waveform 411 is 12, the symbol numbered 12 corresponds to the second time unit 321 numbered 7 in the first time unit 311, and the end time of the symbol numbered 12 in the first waveform 411 is not aligned with the end time or start time of the second time unit 321 numbered 7. To ensure the accuracy of system input and output, within the time duration 40 (the first time period) between the end time of the symbol numbered 12 and the end time of the second time unit 321 numbered 7, 0 is transmitted, the cyclic suffix of the modulation symbols of the first waveform is transmitted, or the cyclic prefix of the modulation symbols of the second waveform is transmitted.

[0085] It can be understood that the symbols corresponding to the above waveforms include: modulation symbols of the waveform and guard intervals; wherein, the guard intervals at least include: 0, cyclic prefix or cyclic suffix. At the same time, the time length of the symbol (symbol length) includes the time length of the modulation symbol and the time length of the guard interval. Among them, the guard interval is used to suppress inter-symbol interference (ISI) and inter-carrier interference (ICI). It can be understood that there are guard intervals between the symbols of some waveforms, such as OFDM; there is no need to set guard intervals between the symbols of some waveforms, such as OOK.

[0086] In an exemplary embodiment, at least one second time unit can also be set between the first waveform and the second waveform. At least one second time unit spaced between the two waveforms can be used as the time for system switching. Exemplarily, referring to Figure 4B , there is one second time unit 321 spaced between the first waveform 411 and the second waveform 422. Exemplarily, during the process of at least one second time unit spaced between the two waveforms, the cyclic suffix of the modulation symbols of the first waveform can be transmitted, or the cyclic prefix of the modulation symbols of the second waveform can be transmitted, or 0. Exemplarily, referring to Figure 4E, there is a second time unit 322 between the first waveform 413 and the second waveform 423. Exemplarily, during at least one second time unit interval between the above two waveforms, the cyclic suffix of the modulation symbols of the first waveform 413 can be transmitted, or the cyclic prefix of the modulation symbols of the second waveform 423 can be transmitted.

[0087] In an exemplary embodiment, as a specific implementation of S220: The start time of the first symbol of the second waveform is aligned with the start time of a certain second time unit in the first time unit. For example, referring to Figure 4A , the start time of the first symbol of the second waveform 421 is aligned with the start time of the second time unit 321 numbered 8 in the first time unit 311. For example, referring to Figure 4B , the start time of the first symbol of the second waveform 422 is aligned with the start time of the second time unit 32 numbered 9 in the first time unit 311. For example, referring to Figure 4C , the start time of the first symbol of the second waveform 423 is aligned with the start time of the second time unit 321 numbered 9 in the first time unit 311. For example, referring to Figure 4D , the start time of the first symbol of the second waveform 424 is aligned with the start time of the second time unit 321 numbered 7 in the first time unit 311. For example, referring to Figure 4E , the start time of the first symbol of the second waveform 423 is aligned with the start time of the second time unit 322 numbered 9 in the first time unit 312.

[0088] As mentioned before, for the convenience of alignment, the length of the second time unit can be the same as the symbol length of the transmitted waveform. Exemplarily, referring to Figure 4A - Figure 4C , the length of the second time unit 321 is the same as the symbol length of the second waveform, which is beneficial to the alignment of the second waveform and the boundary of the second time unit during the signal transmission process, and further facilitates the positioning of the transmission time of the transmitted second waveform. Exemplarily, referring to Figure 4D , the length of the second time unit 321 is the same as the symbol length of the first waveform 412, which is beneficial to the alignment of the first waveform and the boundary of the second time unit during the signal transmission process, and further facilitates the positioning of the transmission time of the transmitted first waveform.

[0089] In an exemplary embodiment, in Figure 4A - Figure 4C , the length of the second time unit 321 is the same as the symbol length of the second waveform. Among them, the number of the transmitted second waveform can be any one of the following methods:

[0090] Method 1: Determine the number of symbols in the second waveform according to the number of the second time unit in the first time unit. For example, referring to Figure 4A, if the number of the second time unit corresponding to the first symbol in the second waveform 421 is 8, the number of the first symbol in the second waveform 421 can also be 8. Further, in the case where both the second waveform and the second time unit adopt OFDM, the lengths of the symbols in the second waveform 421 can be determined based on the number (8) of the first symbol in the second waveform 421 and the above formula (1), so that boundary alignment can be more conveniently achieved. For another example, referring to Figure 4B , if the number of the second time unit corresponding to the first symbol in the second waveform 422 is 9, the number of the first symbol in the second waveform 422 can also be 9. Further, in the case where both the second waveform and the second time unit adopt OFDM, the lengths of the symbols in the second waveform 422 can be determined based on the number (9) of the first symbol in the second waveform 422 and the above formula (1), so that boundary alignment can be more conveniently achieved.

[0091] Method 2: Number the symbols in the second waveform starting from 0. For example, referring to Figure 4C , if the number of the second time unit corresponding to the first symbol in the second waveform 423 is 9, but the number of the first symbol in the second waveform 423 starts from 0. Further, in the case where both the second waveform and the second time unit adopt OFDM, the lengths of the symbols in the second waveform 421 can be determined based on the number (0) of the first symbol in the second waveform 421 and the above formula (1). This numbering method is beneficial to the format uniformity of the symbol numbers of the transmitted waveforms.

[0092] In an exemplary embodiment, in Figure 4D , the length of the second time unit 321 is the same as the symbol length of the first waveform 412. Among them, the number of the transmitted first waveform can be: the serial number of the first OFDM symbol can be selected to start numbering from 0. Then the corresponding OFDM symbols are generated according to formula (1), and this numbering method is beneficial to the format uniformity of the symbol numbers.

[0093] In an exemplary embodiment, in order to ensure correct symbol intervals, avoid generating unexpected errors, and thus ensure the accuracy of the system input and output, if after the transmission of the second waveform ends within the first time unit, the end time of the last symbol of this waveform is not aligned with the start time or end time of the second time unit, then 0 is transmitted within the second time period, and the cyclic suffix of the modulation symbol of the second waveform is transmitted. Among them, the second time period is the time period between the end time of the last symbol of the second waveform and the end time of the second time unit corresponding to the end time of the last symbol of the second waveform. Exemplarily, referring to Figure 4C, the serial number of the last symbol of the second waveform 423 is 4, the symbol numbered 4 corresponds to the second time unit 321 numbered 14 in the first time unit 311, and the end time of the symbol numbered 4 in the second waveform 423 is not aligned with the end time or start time of the second time unit 321 numbered 14. To ensure the accuracy of the system input and output, within the time duration 40' (the second time period) from the end time of the symbol numbered 4 to the end time of the second time unit 321 numbered 14, 0 is transmitted, and the cyclic suffix of the modulation symbols of the second waveform 423 is transmitted. Exemplarily, referring to Figure 4D , the serial number of the last symbol of the second waveform 424 is 12, the symbol numbered 12 corresponds to the second time unit 321 numbered 14 in the first time unit 311, and the end time of the symbol numbered 12 in the second waveform 424 is not aligned with the end time or start time of the second time unit 321 numbered 14. To ensure the accuracy of the system input and output, within the time duration 40' (the second time period) from the end time of the symbol numbered 12 to the end time of the second time unit 321 numbered 14, 0 is transmitted, and the cyclic suffix of the modulation symbols of the second waveform 424 is transmitted.

[0094] In an exemplary embodiment, referring to Figure 4F , if there is still remaining time after sequentially transmitting the symbols corresponding to waveform A and waveform B in the above first time unit. The symbols corresponding to waveform C can be transmitted through the above first frequency domain resource within the remaining time to make full use of the above first frequency domain resource. Among them, the transmission method of the above waveform C is the same as the implementation method of transmitting the second waveform, which will not be elaborated here. It can be understood that within the first time unit, there can be more waveforms that perform time division multiplexing on the overlapping frequency domain resources, and the embodiments of the present application do not limit this.

[0095] In the embodiment provided by method P200, within the first time unit, for example, the first time unit is a time slot. When there is remaining time after transmitting the symbols corresponding to the first waveform through the above first frequency domain resource, the symbols corresponding to other waveforms can also be transmitted through the second frequency domain resource that is frequency domain overlapping with the first frequency domain resource. For example, the second waveform that is time division multiplexed with the above first waveform is transmitted, or for another example, the second waveform and the third waveform are transmitted through different subsets of the above second frequency domain resource, and the second waveform and the third waveform perform frequency division multiplexing on the second frequency domain resource. Thus, the embodiments of the present application provide a scheme for multiplexing the above frequency domain resources within the first time unit, realizing an improvement in the utilization rate of frequency domain resources within one time unit and more effectively using spectrum resources; at the same time, the embodiments of the present application provide a scheme that can flexibly switch different waveforms for transmission on the frequency domain resources with frequency domain overlap, which can improve the flexibility and adaptability of signal transmission and is beneficial to meeting the requirements of various transmission scenarios.

[0096] Meanwhile, in the case where the first time unit contains multiple second time units, it is possible to accurately locate the transmission time of the transmitted waveform, which is beneficial to improving the signal transmission accuracy. This embodiment provides embodiments of multiplexing different types of waveforms for frequency-domain resources that overlap in the frequency domain, thereby facilitating meeting the information transmission requirements in related service scenarios based on frequency-domain resource sharing.

[0097] Based on the above embodiments, Figure 5 FIG. 500 is a schematic flowchart of a method P500 for sharing frequency-domain resources provided in Embodiment 1 of the present application. The method P500 for sharing frequency-domain resources can be a specific implementation of "transmitting symbols corresponding to the first waveform through the first frequency-domain resource" in the method P200. Specifically, in the embodiment provided by the method P500, the above-mentioned first waveform includes multiple groups, and the symbol length (or the sum of symbol lengths) of the first waveform in each group is less than or equal to the length of the above-mentioned second time unit.

[0098] Referring to Figure 5 , the method P500 for sharing frequency-domain resources provided in this embodiment includes the following steps.

[0099] S510. For the i-th group in the first waveform, determine the i-th duration, where the i-th duration is the difference between the length of the second time unit and the symbol length of the i-th group, and i is a positive integer;

[0100] Exemplarily, the length or the sum of lengths of symbols in each group of the above-mentioned first waveform is less than or equal to the length of one second time unit. Among them, the symbol lengths corresponding to different groups can be the same or different. Referring to Figure 6A , the first waveform 414 includes 8 groups, each group includes 3 OOK symbols, the sum of the symbol lengths of each group is less than or equal to the length of one second time unit 321, and at the same time Figure 6A it is shown that the sum of the symbol lengths of each group in the first waveform 414 is equal.

[0101] To facilitate the positioning of each group of signals, the start time of the first symbol of each group of signals can be aligned with the boundary of the second time unit, such as S520; or, the end time of the last symbol of each group of signals can be aligned with the boundary of the second time unit, such as S520'.

[0102] Exemplarily, to facilitate the positioning of each group of signals in the first waveform, determine the i-th duration. Specifically, the i-th duration is the difference between the length of the second time unit and the sum of the symbol lengths in the i-th group, and can be expressed by formula (2).

[0103] Δ i = L - l i (2)

[0104] where, Δ i represents the i-th duration, L represents the length of the second time unit, and l i represents the sum of the symbol lengths in the i-th group.

[0105] Refer to Figure 6A , the first waveform 414 includes 8 groups, each group includes 3 OOK symbols, and the sum of the symbol lengths in each group is less than or equal to a second time unit 321. It is possible to determine the 8 durations corresponding to the 8 groups of symbols of the first waveform 414: Δ1 to Δ8.

[0106] S520. In the i-th duration starting from the start time of the second time unit in the first time unit, transmit the cyclic prefix or 0 of the i-th group of symbols in the first waveform through the first frequency domain resource; in the next duration of the above second time unit, transmit the i-th group of symbols in the first waveform through the first frequency domain resource.

[0107] Exemplarily, for the i-th group of waveforms of the first waveform terminal, starting from the start time of a second time unit (denoted as s) in the first time unit, transmit the cyclic prefix of the modulation symbols of the i-th group of the first waveform through the first frequency domain resource within the i-th duration; then, within the next duration (L - Δ i ) of the second time unit s, transmit the i-th group of symbols through the first frequency domain resource. For example, refer to Figure 6A , for the first group of waveforms in the first waveform, starting from the start time of a second time unit (denoted as s1) in the first time unit, transmit the cyclic prefix of the modulation symbols of the first group in the first waveform through the first frequency domain resource within the Δ1 duration; then, within the next duration (L - Δ1) of the second time unit s1, transmit the first group of symbols in the first waveform through the first frequency domain resource. For the second group of waveforms in the first waveform, starting from the start time of a second time unit (denoted as s2) in the first time unit, transmit the cyclic prefix of the modulation symbols of the second group in the first waveform through the first frequency domain resource within the Δ2 duration; then, within the next duration (L - Δ2) of the second time unit s2, transmit the second group of symbols in the first waveform through the first frequency domain resource. And so on, transmit all groups of symbols of the first waveform 414 through the first frequency domain resource. Refer to Figure 6A , each group of symbols in the first waveform 414 is aligned with the boundary of the second time unit (such as an OFDM symbol), so as to facilitate the positioning of each group of symbols in the first waveform 414.

[0108] S520'. Starting from the start time of the second time unit in the first time unit, transmit the i-th group of symbols in the first waveform through the first frequency domain resource; within the next i-th duration of the above second time unit, transmit the cyclic suffix or 0 of the modulation symbols of the i-th group in the first waveform through the first frequency domain resource.

[0109] Exemplarily, for the \(i\) -th group of waveforms of the first waveform, the \(i\) -th group of symbols is transmitted through the first frequency - domain resource starting from the start time of a second time unit (denoted as \(s\)) within the first time unit; then, within the \(i\) -th duration following the second time unit \(s\), the cyclic suffix of the modulated symbols of the \(i\) -th group of the first waveform is transmitted through the first frequency - domain resource. For example, referring to Figure 6B , for the first group of waveforms in the first waveform, starting from the start time of a second time unit (denoted as \(s1\)) within the first time unit, the first - group symbols in the first waveform are transmitted through the first frequency - domain resource within a duration of \((L-\Delta1)\); then, within a duration of \(\Delta1\) following the second time unit \(s1\), the cyclic suffix of the modulated symbols of the first group in the first waveform is transmitted through the first frequency - domain resource. For the second group of waveforms in the first waveform, starting from the start time of a second time unit (denoted as \(s2\)) within the first time unit, the second - group symbols in the first waveform are transmitted through the first frequency - domain resource within a duration of \((L - \Delta2)\); then, within a duration of \(\Delta2\) following the second time unit \(s2\), the cyclic suffix of the modulated symbols of the second group in the first waveform is transmitted through the first frequency - domain resource. And so on, all groups of symbols of the first waveform 414 are transmitted through the first frequency - domain resource. Referring to Figure 6B , each group of symbols in the first waveform 414 is aligned with the boundary of the second time unit (such as an OFDM symbol), which facilitates the positioning of each group of symbols in the first waveform 414.

[0110] Referring to Figure 6A and Figure 6B , the first waveform 414 is a multi - group of OOK symbols, and there is no need for a guard interval between two consecutive OOK symbols in each group. After sending 8 groups of OOK symbols to the AIoT device on BWP1 within a certain slot (the first time unit), the data transmission is completed or the AIoT device needs a certain amount of time for energy storage. At this time, if the above - mentioned slot (the first time unit) still has remaining time, it can be switched to the second waveform 425, that is, the symbols corresponding to the OFDM waveform. Specifically, data is sent to the device receiving the OFDM waveform on BWP1, so as to transmit two waveforms using the same spectral resource BWP1 to maximize the resource utilization rate of the system. Among them, regarding the transmission of the second waveform 425 through the first frequency - domain resource, reference can be made to the embodiments provided by method P400, which will not be elaborated here.

[0111] In the solution provided by method P500, there is a transmission scheme for time - division multiplexing of frequency - domain resources within a first time unit. In the solution provided by this embodiment, not only can the transmission time of the transmitted waveform be located, but also the precise positioning of each group within the same waveform can be achieved, which is beneficial to improving the signal transmission accuracy and enhancing the frequency - domain resource sharing experience.

[0112] Based on the above embodiments, Figure 7 FIG. Figure 7 is a schematic flowchart of a method P700 for sharing frequency domain resources provided in the first embodiment of this application. The execution subject of the method P700 for sharing frequency domain resources can be a network side device or a terminal device. The method P700 is implemented based on the method P200, and the implementation methods described in the method P200 can be applied to this embodiment and achieve the same technical effects.

[0113] Referring to Figure 7 , the method P700 for sharing frequency domain resources provided in this embodiment includes the following steps.

[0114] S710: Within a first time unit, send symbols corresponding to a first waveform to a first device through a first frequency domain resource; and S720: Within the first time unit, send symbols corresponding to a second waveform to a second device through a second frequency domain resource, where the first waveform and the second waveform perform time division multiplexing on the frequency domain resources within the first time unit.

[0115] Among them, the above-mentioned first device and second device can be different devices or the same device as signal receiving devices.

[0116] Exemplarily, with the development of 6G, many emerging radio services and emerging applications have emerged, and more waveforms are required to meet different needs. For example, in the field of the Internet of Things, single-carrier waveform technology can better meet the needs of underlying communication of Internet of Things devices, while reducing the technical threshold and improving signal transmission stability. For the field of vehicle-to-everything (V2X), waveform technology based on cellular and vehicle-to-vehicle communication can improve communication reliability and bandwidth transmission rate. In the integrated communication and sensing scenario, OTFS waveform can better demodulate the Doppler domain. In the high-capacity scenario, using efficient modulation technology can better ensure data transmission. For example, Orthogonal Multiple Access (OMA) technology can better improve spectrum efficiency, achieve higher bandwidth utilization, and improve the service experience. These waveform technologies all have their own advantages and application scopes and can meet the needs of different scenarios and applications.

[0117] The device for signal transmission through the embodiment of this application (the above-mentioned signal transmission device) can belong to any one of the following information: network side device, user terminal, AIoT terminal device, Internet of Things terminal device, vehicle-to-everything terminal device, and sensing terminal device.

[0118] The first waveform and the second waveform perform time-division multiplexing on frequency-domain resources within the above-mentioned first time unit. Both the first device and the second device belong to signal receiving devices, and they should be either network-side devices or terminal devices at the same time. Specifically, when the signal receiving devices (the first device and the second device) are network-side devices, the signal sending device can be any one of the following: user terminal, AIoT terminal device, Internet of Things terminal device, vehicle-to-everything terminal device, and sensing terminal device. Similarly, when the signal sending device is a network-side device, the signal receiving devices (such as the above-mentioned first device and second device) can be any one of the following: user terminal, AIoT terminal device, Internet of Things terminal device, vehicle-to-everything terminal device, and sensing terminal device. For example, when the first device is a user terminal and the second device is an AIoT, BWP2 was originally used for the transmission of signals corresponding to AIoT terminal devices. However, within a certain first time unit, after transmitting the first waveform a to the AIoT terminal device, the device needs to store energy. Therefore, there is no need to send signals to the AIoT device during the idle time within the above-mentioned first time unit. Then, the second waveform b can be transmitted to the user terminal during this idle time. Among them, the first waveform a and the second waveform b perform time-division multiplexing on BWP2.

[0119] It should be noted that the deployment of AIoT terminal devices can be divided into the following three scenarios.

[0120] Scenario 1: AIoT is deployed in the system bandwidth of NR, also known as in-band deployment. In this scenario, in one implementation, the same base station serves both AIoT devices and NR UEs. In another implementation, different base stations serve AIoT devices and NR UEs.

[0121] Scenario 2: AIoT is deployed in the guard interval of the NR system, also known as guard band deployment. In this scenario, in one implementation, the same base station serves both AIoT devices and NR UEs. In another implementation, different base stations serve AIoT devices and NR UEs.

[0122] Scenario 3: AIoT is deployed outside the guard interval of the NR system (obviously, not within the system bandwidth of NR either), also known as stand-alone deployment. In this scenario, usually the base station only serves AIoT devices.

[0123] As described above, within the first time unit, symbols corresponding to a third waveform may also be transmitted through at least one of the first frequency-domain resource and the second frequency-domain resource; wherein, the third waveform is frequency-division multiplexed with at least one of the first waveform and the second waveform.

[0124] In an exemplary embodiment, if within the first time unit, symbols corresponding to the third waveform are sent to a third device through a first frequency-domain resource; wherein, the third waveform is frequency-division multiplexed with the first waveform for the first frequency-domain resource. In this embodiment, one of the first device and the third device may be a network-side device and the other may be a terminal device, or both may be network-side devices, or both may be terminal devices. The embodiments of the present application do not make any limitations in this regard. Specifically, the first device and the third device respectively belong to any one of the following information: network-side device; user terminal; artificial intelligence Internet of Things terminal device; Internet of Things terminal device; vehicle-to-everything terminal device; sensing terminal device.

[0125] In the solution provided by method P700, in the case where the first waveform and the second waveform are time-division multiplexed for the frequency-domain resource within the first time unit, if the first device and the second device as information receiving devices are network-side devices, the information sending device may be any one of many types of terminal devices; if the information sending device is a network-side device, and the first device and the second device as information receiving devices may be any one of many types of terminal devices; in addition, the device receiving the above-mentioned third waveform may be a network-side device or one of many types of terminal devices. It can be seen that the frequency-domain resource sharing solution provided by the embodiments of the present application can be applied to multiple scenarios and has high practicability.

[0126] Based on the above embodiments, Figure 8 FIG. P800 is a schematic flowchart of a method for sharing frequency-domain resources provided in Embodiment 1 of the present application. The execution subject of the method for sharing frequency-domain resources P800 may be a network-side device or a terminal device. The implementation manners described in the foregoing embodiments can all be applied to this embodiment and can achieve the same technical effects. Specifically, method P800 is used to introduce an embodiment of transmitting at least two waveforms that are time-division multiplexed for the frequency-domain resource within multiple first time units.

[0127] Refer to Figure 8 , the method for sharing frequency-domain resources P800 provided in this embodiment includes the following steps.

[0128] S810. In the j-th first time unit, transmit the symbols corresponding to the fourth waveform through the second frequency-domain resource, and transmit the symbols corresponding to the fifth waveform through the second frequency-domain resource. The fourth waveform and the fifth waveform are supported waveforms, and the fourth waveform and the fifth waveform time-division multiplex the frequency-domain resources in the j-th first time unit.

[0129] S820. In the k-th first time unit, transmit the symbols corresponding to the sixth waveform through the second frequency-domain resource, and transmit the symbols corresponding to the seventh waveform through the second frequency-domain resource. The sixth waveform and the seventh waveform are supported waveforms, and the sixth waveform and the seventh waveform time-division multiplex the frequency-domain resources in the k-th first time unit. j and k are different positive integers.

[0130] Each of the above embodiments provides a multi-waveform multiplexing mode for the frequency-domain resources within a first time unit. In the solution provided by method P800, the multi-waveform multiplexing of the frequency-domain resources within the first time unit can be configured to be periodic. Exemplarily, through RRC semi-static configuration, as follows: As Figure 4A The multi-waveform multiplexing mode shown can be defined as mode 1, as Figure 4C The multi-waveform multiplexing mode shown can be defined as mode 2, and then mode 1 and mode 2 will be alternately used for transmission. Exemplarily, dynamically adjust using MAC CE signaling or L1 signaling. For example, after the first time using the multi-waveform multiplexing mode shown as Figure 4C Adjust to use the second waveform 423 shown as Figure 4C for transmission according to the requirement, and use MAC CE signaling or L1 signaling for indication; keep using the waveform shown as Figure 4C the second waveform 423 for transmission in the subsequent time slots until there is a need for waveform adjustment; for example, when there is a need for waveform adjustment, adjust the corresponding waveform transmission method according to the requirement and send relevant signaling indication.

[0131] The solution provided by method P800 can improve the utilization rate of the frequency-domain resources within multiple first time units, and also provides a flexible adjustment method, which is beneficial to meeting diverse actual requirements.

[0132] Figure 9FIG. 0 is a schematic flowchart of the frequency-domain resource sharing method P900 provided in the first embodiment of the present application. The execution subject of the frequency-domain resource sharing method P900 is a signal receiving device, which may be, for example, a network-side device 120 or a terminal device 110. That is to say, the solution provided in the present application can be adopted during the network-side device 120 receiving the uplink transmission data of the terminal device 110; the solution provided in the present application can be adopted during the terminal device 110 receiving the downlink transmission of the network-side device 120.

[0133] Refer to Figure 9 , the frequency-domain resource sharing method P900 provided in this embodiment includes the following steps.

[0134] S910. Receive the symbol corresponding to the first waveform, where the symbol corresponding to the first waveform is sent by the signal sending device through the first frequency-domain resource in the first time unit, and in the first time unit, the signal sending device also transmits the symbol corresponding to the second waveform through the second frequency-domain resource, and the first waveform and the second waveform are supported waveforms; where the first frequency-domain resource and the second frequency-domain resource overlap in the frequency domain, and the first waveform and the second waveform perform time division multiplexing on the frequency-domain resource in the first time unit.

[0135] Wherein, the above signal sending device may belong to any one of the following information: network-side device, user terminal, AIoT terminal device, Internet of Things terminal device, vehicle-to-everything terminal device, and sensing terminal device.

[0136] Since the first waveform and the second waveform perform time division multiplexing on the frequency-domain resource in the first time unit, the first device receiving the first waveform and the second device receiving the second waveform both belong to the signal receiving device, and should be the same network-side device or the same terminal device. Specifically, when the above signal sending device is a network-side device, the above first device and the second device belong to any one of the following information: user terminal, artificial intelligence Internet of Things terminal device, Internet of Things terminal device, vehicle-to-everything terminal device, sensing terminal device. When the first device and the second device belong to the network-side device, the above signal sending device is any one of the following information: user terminal, artificial intelligence Internet of Things terminal device, Internet of Things terminal device, vehicle-to-everything terminal device, sensing terminal device.

[0137] For example, when the first device that receives the symbol corresponding to the first waveform is an AIoT device, and the second device that receives the symbol corresponding to the second waveform is a user terminal, BWP2 is originally used for transmitting signals corresponding to AIoT terminal devices. However, within a certain first time unit, after transmitting the first waveform a to the AIoT terminal device, the device needs to store energy. Therefore, there is no need to send signals to the AIoT device during the idle time within the first time unit. Then, during this idle time, the second waveform b can be transmitted to the user terminal through BWP1 that is frequency-domain overlapped with BWP2. Among them, the first waveform a and the second waveform b time-division multiplex the frequency-domain resources within the same first time unit.

[0138] In an exemplary embodiment, within the first time unit, the symbol corresponding to the first waveform is transmitted to the AIoT terminal device through the first frequency-domain resource. After receiving the symbol corresponding to the first waveform, the AIoT terminal may store energy and be in a state of not transmitting or receiving signals. If there is still remaining time within the first time unit after transmitting the first waveform, in the embodiments of the present application, symbols corresponding to other waveforms may also be transmitted through the second frequency-domain resource that is frequency-domain overlapped with the first frequency-domain resource. For example, symbols corresponding to the second waveform are sent to a certain vehicle networking terminal device. Thus, time-division multiplexing of the above frequency-domain resources is achieved, which is beneficial to improving the utilization rate of the frequency-domain resources within the first time unit.

[0139] In an exemplary embodiment, within the first time unit, the signal sending device also transmits the symbol corresponding to the third waveform through the first frequency-domain resource; among them, the third waveform frequency-division multiplexes the first frequency-domain resource with at least one of the first waveform and the second waveform. For example, within the first time unit, when the second waveform and the third waveform satisfy frequency-division multiplexing, the second waveform and the third waveform respectively transmit signals through different subsets of the second frequency-domain resource. For example, within the first time unit, when the first waveform and the third waveform satisfy frequency-division multiplexing, the first waveform and the third waveform respectively transmit signals through different subsets of the first frequency-domain resource. Another example is that within the first time unit, when the third waveform respectively satisfies frequency-division multiplexing with the first waveform and the second waveform, the third waveform and the first waveform respectively transmit signals through different subsets of the first frequency-domain resource, and the third waveform and the second waveform respectively transmit signals through different subsets of the first frequency-domain resource. Thus, frequency-division multiplexing of the above frequency-domain resources is achieved, which is beneficial to further improving the utilization rate of the frequency-domain resources.

[0140] If the third waveform is frequency-division multiplexed with the first waveform on the first frequency-domain resource, one of the third device that receives the symbol corresponding to the third waveform and the first device that receives the first waveform may be a network-side device and the other may be a terminal device, or both may be network-side devices, or both may be terminal devices. The embodiments of the present application do not limit this. Specifically, the third device that receives the symbol corresponding to the third waveform belongs to any one of the following information: network-side device, user terminal, artificial intelligence Internet of Things terminal device, Internet of Things terminal device, vehicle-to-everything terminal device, sensing terminal device.

[0141] In an exemplary embodiment, the first frequency-domain resource and the second frequency-domain resource overlap in the frequency domain. Specifically, the first frequency-domain resource and the second frequency-domain resource multiplexed within the first time unit may belong to high-frequency band frequency-domain resources, or the first frequency-domain resource and the second frequency-domain resource may also be medium- and low-frequency band frequency-domain resources. Exemplarily, the multiplexed frequency-domain resource is any one partial bandwidth (Bandwidth Part, BWP). It can be understood that the BWP divides the 5G spectrum into many small blocks within a certain period of time. Each BWP can use different parameter sets, and its bandwidth, subcarrier spacing, and other control parameters can all be different. It is equivalent to dividing several sub-cells with different configurations within the 5G cell to adapt to different types of terminals and service types.

[0142] In an exemplary embodiment, the length of the above-mentioned first time unit may be determined according to the symbol length of a specific waveform. Wherein, the above-mentioned specific waveform refers to any waveform supported for transmission in the above-mentioned first frequency domain resource or the second frequency domain resource. Exemplarily, the length of the above-mentioned first time unit may also be determined according to the symbol length of other waveforms that are not supported for transmission temporarily through the above-mentioned first frequency domain resource or the second frequency domain resource. The embodiments of the present application do not limit this. Exemplarily, the length of the first time unit may specifically be the symbol length of a waveform, or the sum of the symbol lengths of multiple symbols of the same waveform. For example, the length of a first time unit may be the symbol length of an Orthogonal Frequency Division Multiplexing (OFDM), or the sum of the symbol lengths of multiple OFDMs. Exemplarily, the length of the above-mentioned first time unit may also be determined according to the symbol lengths of other waveforms, such as the symbol length of Gaussian minimum shift keying (GMSK), the symbol length of On-Off Keying (OOK), the symbol length of Amplitude Shift Keying (ASK), the symbol length of Frequency Shift Keying (FSK), the symbol length of Phase Shift Keying (PSK), the symbol length of Orthogonal Time Frequency Space (OTFS), etc. Exemplarily, the length of a first time unit may also be the sum of the symbol lengths of different types. For example, the length of the first time unit is the sum of the symbol length of an OFDM and the symbol length of an OOK.

[0143] In an exemplary embodiment, the length of the above-mentioned first time unit may also be a fixed duration, such as 1 ms.

[0144] In an exemplary embodiment, the above-mentioned first time unit is a slot.

[0145] Exemplarily, regarding the method for determining the length of the above-mentioned first time unit, it can be defined by a communication protocol. Another exemplarily, regarding the method for determining the length of the above-mentioned first time unit, it can also be configured by semi-static signaling. For example, through the semi-static configuration of Radio Resource Control (RRC), during the multiplexing process of frequency domain resource A, the length of the first time unit is determined according to the symbol length of OFDM. Another exemplarily, regarding the method for determining the length of the above-mentioned first time unit, it can also be configured by dynamic signaling according to actual requirements. For example, using MAC CE signaling or L1 signaling for dynamic adjustment, during the multiplexing process of frequency domain resource A, the first time unit adopts a fixed duration a during the signal transmission in a certain time period, and the first time unit adopts a fixed duration b during the signal transmission in another time period, and MAC CE signaling or L1 signaling is used for indication.

[0146] In an exemplary embodiment, for the convenience of positioning the transmission time of the above-mentioned time-division multiplexed waveform. The above-mentioned first time unit can be composed of multiple second time units. Exemplarily, the start time of the first symbol of each waveform for time-division multiplexing of the above-mentioned frequency domain resource is aligned with the start times of different second time units in the first time unit, so as to achieve the positioning of the waveform for time-division multiplexing.

[0147] In an exemplary embodiment, the length of the above-mentioned second time unit can be determined according to the symbol length of a specific waveform. Wherein, the above-mentioned specific waveform refers to any waveform supported for transmission in the above-mentioned first frequency domain resource or second frequency domain resource. Exemplarily, the length of the above-mentioned second time unit can also be determined according to the symbol length of other waveforms that are not supported for transmission temporarily through the above-mentioned first frequency domain resource or second frequency domain resource. The embodiments of the present application do not make any limitations in this regard.

[0148] Exemplarily, the length of the above-mentioned second time unit can also be determined according to the symbol length of orthogonal frequency division multiplexing (OFDM). Exemplarily, the length of the second time unit can specifically be the symbol length of a waveform. As Figure 3A shown, the length of a second time unit 321 is the symbol length of an OFDM. Taking the reference subcarrier spacing of 15 KHz as an example, the length of one second time unit 321 is the symbol length of an OFDM, and one first time unit 311 is a slot. Figure 3AA first time unit 311 shown contains a plurality of second time units 312, wherein the cyclic prefix (CP) of the OFDM symbol numbered 0 and the cyclic prefix of the OFDM symbol numbered 7 are extended cyclic prefixes (ECPs), and the cyclic prefixes of OFDM symbols with other numbers are normal cyclic prefixes (NCPs). It can be seen that the lengths between different second time units can be the same or different. Specifically, in this embodiment, the length of the second time unit is calculated as shown in formula (3) below.

[0149]

[0150]

[0151]

[0152] where κ = 64, which is the ratio of the basic time unit in the LTE system to the basic time unit in the NR system. 5G NR will use the parameter μ to represent the carrier spacing. For example, μ = 0 represents the same carrier spacing as 15 kHz in the LTE system. The basic time unit Tc = 1 / (480 * 1000 * 4096) = 0.509 ns.

[0153] Exemplarily, the length of the second time unit can specifically also be the sum of the lengths of multiple symbols of the same waveform. As Figure 3B shown, the length of a second time unit 322 is the sum of the lengths of two OFDM symbols. It can be understood that the length of the above-mentioned second time unit can also be the sum of the lengths of 3 or more OFDM symbols, and this application embodiment does not make a limitation on this.

[0154] In an exemplary embodiment, the length of the above-mentioned second time unit can also be determined according to the symbol lengths of other waveforms, such as the symbol length of GMSK, the symbol length of OOK, the symbol length of ASK, the symbol length of FSK, the symbol length of PSK, the symbol length of OTFS, etc. Exemplarily, the length of a second time unit can also be the sum of the symbol lengths of different types. For example, the length of the second time unit is the sum of the length of an OFDM symbol and the length of an OOK symbol.

[0155] In an exemplary embodiment, the length of the above-mentioned second time unit can take a value of: the symbol length of the target waveform (any one of the multiple waveforms) among the multiple waveforms transmitted within the first time unit. Thus, it is beneficial to align the target waveform with the boundary of the second time unit during the signal transmission process, and further facilitate the positioning of the transmission time of the transmitted signal.

[0156] In an exemplary embodiment, the length of the above second time unit may also be a fixed duration. Exemplarily referring to Figure 3C , the duration of each second time unit is a fixed value. For example, the length of each second time unit is 0.1 ms.

[0157] Exemplarily, regarding the method for determining the length adopted by the above second time unit, it can be defined by a communication protocol. Another exemplarily, regarding the method for determining the length adopted by the above second time unit, it can also be configured by semi-static signaling. For example, through semi-static configuration of Radio Resource Control (RRC), during the multiplexing process of frequency domain resource A, the length of the second time unit is the symbol length of waveform a. Still another exemplarily, regarding the method for determining the length adopted by the above second time unit, it can also be configured by dynamic signaling. For example, using MAC CE signaling or L1 signaling for dynamic adjustment, during the multiplexing process of frequency domain resource A, during the signal transmission in a certain time period, the second time unit adopts a fixed duration a, and during the signal transmission in another time period, the second time unit adopts a fixed duration b, and MAC CE signaling or L1 signaling is used for indication.

[0158] Exemplarily, referring to Figure 3A , the first time unit 311 includes 14 second time units 321. Referring to Figure 3B , the first time unit 312 includes 7 second time units 322. Referring to Figure 3C , the first time unit 313 includes 10 second time units 323. Among them, the number of the second time units included in the first time unit can also be defined by a communication protocol. It can also be configured by semi-static signaling. For example, through RRC semi-static configuration, during the multiplexing process of frequency domain resource A, each first time unit includes 10 second time units. It can also be configured by dynamic signaling. For example, using MAC CE signaling or L1 signaling for dynamic adjustment, during the multiplexing process of frequency domain resource A, during the signal transmission in a certain time period, each first time unit includes 10 second time units, and during the signal transmission in another time period, each first time unit includes 14 second time units, and MAC CE signaling or L1 signaling is used for indication.

[0159] In an exemplary embodiment, the above-mentioned multiple waveforms may include the following types: OFDM waveform, OOK waveform, ASK waveform, FSK waveform, PSK waveform, GMSK waveform, Frequency Modulated Continuous Wave (FMCW), etc. They may also be other types of waves, and the embodiments of the present application do not limit this. Among them, the waveforms that perform time division multiplexing on the above frequency domain resources may be different types of waveforms or the same type of waveforms, and the embodiments of the present application do not limit this. That is to say, in the embodiments provided by the present application, the scheme of flexibly switching different waveforms for transmission on the frequency domain resources within the first time unit can improve the flexibility and adaptability of signal transmission, which is conducive to meeting the requirements of various transmission scenarios.

[0160] In the embodiment provided by method P900, within the first time unit, for example, the first time unit is a time slot. When there is remaining time after transmitting the symbols corresponding to the first waveform through the first frequency domain resource, symbols corresponding to other waveforms can also be transmitted through the second frequency domain resource that overlaps with the first frequency domain resource in the frequency domain. For example, the second waveform that is time division multiplexed with the above first waveform is transmitted. Another example is that within the above first time unit, the third waveform is transmitted through at least one of the above first frequency domain resource and the second frequency domain resource, and the third waveform is frequency division multiplexed with at least one of the second waveform and the first waveform. Thus, the embodiment of the present application provides a scheme for multiplexing the above frequency domain resources within the first time unit, realizing the improvement of the utilization rate of frequency domain resources within one time unit and more effectively using spectrum resources. At the same time, the embodiment of the present application provides a scheme that can flexibly switch different waveforms for transmission on the frequency domain resources that overlap in the frequency domain, which can improve the flexibility and adaptability of signal transmission and is conducive to meeting the requirements of various transmission scenarios.

[0161] Based on the above embodiments, Figure 10 It is a schematic flowchart of the frequency domain resource sharing method P1000 provided by Embodiment 1 of the present application. This embodiment is used to describe the signaling interaction between signal transceiver devices during the frequency domain resource sharing process. Figure 10 It is a signaling flowchart of a frequency domain resource sharing method P1000 provided by the embodiments of the present application. Among them, the implementation manners recorded in the foregoing embodiments can all be applied to this embodiment and can achieve the same technical effects. As Figure 10 shown, the frequency domain resource sharing method P1000 provided by this embodiment includes the following steps.

[0162] S1001. The signal sending device starts to send the signal corresponding to the first waveform to the signal receiving device 1 through the first frequency domain resource at the s1-th second time unit in the k-th first time unit and finishes sending within the s2-th second time unit.

[0163] S1002. The signal sending device starts to send the signal corresponding to the second waveform to the signal receiving device 2 through the second frequency domain resource that overlaps with the first frequency domain resource in the frequency domain at the m1-th second time unit in the k-th first time unit, and finishes sending within the m2-th second time unit, where m1 > s2.

[0164] Reference Figure 11 In the k-th first time unit, the signal sending device starts to send the signal corresponding to the first waveform 111 to the signal receiving device 1 through the first frequency domain resource at the s1-th (numbered 0) second time unit, and finishes sending within the s2-th (numbered 7) second time unit. And there is remaining time in the k-th first time unit after the sending ends. Then, the second waveform 112 can be transmitted in this first time unit, so as to improve the utilization rate of the frequency domain resource in the first time unit and meet the requirements of different services. Among them, the first frequency domain resource and the second frequency domain resource overlap in the frequency domain.

[0165] Exemplarily, in order to ensure the accuracy of the system input and output, within the time duration 110 (the first time period) from the end time of the symbol numbered 5 in the first waveform 111 to the end time of the second time unit numbered 7 in the k-th first time unit, 0 is transmitted, the cyclic suffix of the modulation symbol of the first waveform 111 is transmitted, or the cyclic prefix of the modulation symbol of the second waveform 112 is transmitted.

[0166] Reference Figure 11 In the k-th first time unit, the signal sending device starts to send the signal corresponding to the second waveform 112 to the signal receiving device 2 through the first frequency domain resource at the m1-th (numbered 8) second time unit, and finishes sending within the m2-th (numbered 14) second time unit.

[0167] Therefore, in the embodiment provided by the method P1000, within the first time unit, the frequency domain resources that overlap in the frequency domain can meet the service requirements of different signal receiving devices and improve the utilization rate of the frequency domain resources within the first time unit.

[0168] Based on the above embodiments, Figure 12 FIG. P1200 is a schematic flowchart of the method for sharing frequency domain resources provided in the first embodiment of the present application. This embodiment is used to describe the signaling interaction between signal sending and receiving devices during the process of sharing frequency domain resources. Figure 12 FIG. P1200 is a signaling flowchart of a method for sharing frequency domain resources provided in an embodiment of the present application. Among them, the implementation manners recorded in the foregoing embodiments can all be applied to this embodiment and can achieve the same technical effects. As Figure 12 shown, the method for sharing frequency domain resources P1200 provided in this embodiment includes the following steps.

The signal sending device starts to send the signal corresponding to the first waveform to the signal receiving device A through the first frequency-domain resource at the s1-th second time unit in the k-th first time unit, and finishes sending within the s2-th second time unit. And, S1202. The signal sending device starts to send the signal corresponding to the second waveform to the signal receiving device A through the second frequency-domain resource overlapping with the first frequency-domain resource in the frequency domain at the m1-th second time unit in the k-th first time unit, and finishes sending within the m2-th second time unit, where m1 > s2.

[0170] Reference Figure 13 , within the k-th first time unit, the signal sending device starts to send the signal corresponding to the first waveform 131 to the signal receiving device A through the first frequency-domain resource at the s1-th (numbered 0) second time unit. And finishes sending within the s2-th (numbered 7) second time unit, and there is remaining time in the k-th first time unit after the sending ends. Then the second waveform 132 can be transmitted within this first time unit, thereby improving the utilization rate of the frequency-domain resource within the first time unit and being able to meet the requirements of different services.

[0171] Exemplarily, in order to ensure the accuracy of the system input and output, within the time duration 130 (the first time period) from the end time of the symbol numbered 5 in the first waveform 131 to the end time of the second time unit numbered 7 in the k-th first time unit, 0 is transmitted, the cyclic suffix of the modulation symbols of the first waveform 131 is transmitted, or the cyclic prefix of the modulation symbols of the second waveform 132 is transmitted.

[0172] Within the k-th first time unit, the signal sending device starts to send the signal corresponding to the second waveform 132 to the signal receiving device A through the first frequency-domain resource at the m1-th (numbered 8) second time unit. And finishes sending within the m2-th (numbered 14) second time unit.

[0173] S1203. The signal sending device starts to send the signal corresponding to the third waveform to the signal receiving device B through the first frequency-domain resource at the s3-th second time unit in the h-th first time unit, and finishes sending within the s4-th second time unit. And, S1304. The signal sending device starts to send the signal corresponding to the fourth waveform to the signal receiving device C through the second frequency-domain resource overlapping with the first frequency-domain resource in the frequency domain at the m3-th second time unit in the h-th first time unit, and finishes sending within the m4-th second time unit, where m3 > s4.

[0174] Reference Figure 13, within the h-th (e.g., h = k + 1) first time unit, the signal sending device starts to send the signal corresponding to the third waveform 133 to the signal receiving device B through the first frequency domain resource at the s3-th (numbered 0) second time unit, and finishes sending at the s4-th (numbered 5) second time unit. And there is remaining time in the h-th first time unit after the sending ends. Then, the fourth waveform 134 can be transmitted within this first time unit, thereby improving the utilization rate of the frequency domain resource within the first time unit and also meeting the requirements of different services.

[0175] Exemplarily, to ensure the system switching time, at least one second time unit can be set between the third waveform 133 and the fourth waveform 134. During the duration of the second time unit (numbered 6) that is separated, 0 is transmitted, the cyclic suffix of the modulation symbols of the third waveform 133 is transmitted, or the cyclic prefix of the modulation symbols of the fourth waveform 134 is transmitted.

[0176] Within the h-th first time unit, the signal sending device starts to send the signal corresponding to the second waveform 132 to the signal receiving device C through the first frequency domain resource at the m3-th (numbered 7) second time unit, and finishes sending at the m4-th (numbered 14) second time unit.

[0177] Exemplarily, to ensure the accuracy of the system input and output, within the duration 130' (second time period) from the end time of the symbol numbered 5 in the fourth waveform 134 to the end time of the second time unit numbered 14 in the h-th first time unit, 0 is transmitted, and the cyclic suffix of the modulation symbols of the fourth waveform 134 is transmitted.
