[0002] This disclosure is based on and claims priority to Chinese Patent Application No. 2025103762683, filed on March 27, 2025, entitled “Communication Method, Storage Medium, Electronic Device and Computer Program Product”, and incorporates the entire contents of that patent application by reference. Technical Field

[0003] This disclosure relates to the field of communications, and more specifically, to a communication method, storage medium, electronic device, and computer program product. Background Technology

[0004] Within the current 5G communication system framework, uplink and downlink employ different multi-carrier modulation techniques to optimize signal transmission. Specifically, the uplink channel supports Discrete Fourier Transform-Spread Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) and Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM), while the downlink primarily uses CP-OFDM technology.

[0005] In DFT-s-OFDM technology, a Phase Tracking Reference Signal (PTRS) must be inserted into each DFT-s-OFDM symbol to accurately estimate and compensate for phase noise—a signal phase change caused by frequency source instability. As communication technology advances to higher frequency bands, carrier frequencies increase significantly, and the corresponding subcarrier spacing also increases, resulting in a shorter time-domain duration for each symbol (especially in the THz band). This change exacerbates the relative overhead of the Cyclic Prefix (CP) and PTRS, as their time-domain length remains constant while the time-domain length of the useful signal decreases. Therefore, the increased load on CP and PTRS reduces the overall spectrum utilization and negatively impacts system performance.

[0006] There is currently no good solution to the above problems in the standard. Summary of the Invention

[0025] The embodiments of this disclosure will be described in detail below with reference to the accompanying drawings and examples.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] The method embodiments provided in this disclosure can be operated in 5G, 6G and other future communication systems.

As shown in Figure 1, the system includes the following structure: core network (CN), radio access network (RAN), and user equipment.

[0028] The core network is the core part of the network, responsible for handling control and user data. The core network includes multiple network functions (NFs), such as the Access and Mobility Management Function (AMF), Session Management Function (SMF), and User Plane Function (UPF).

[0031] The method embodiments provided in this disclosure can be run in user equipment, base stations, or other network-side network elements in the above-described communication system. The user equipment includes, but is not limited to, mobile terminals, computer terminals, or similar computing devices. Taking a mobile terminal as an example, FIG2 is a hardware structure block diagram of the mobile terminal running in the method embodiments of this disclosure. As shown in FIG2, the mobile terminal may include one or more (only one is shown in FIG2) processors 22 (processor 22 may include, but is not limited to, microprocessors such as MCUs or programmable logic devices such as FPGAs) and a memory 24 for storing data. The mobile terminal may also include a transmission device 26 for communication functions and an input / output device 28. Those skilled in the art will understand that the structure shown in FIG2 is merely illustrative and does not limit the structure of the mobile terminal. For example, the mobile terminal may include more or fewer components than shown in FIG2, or have a different configuration than shown in FIG2.

[0032] The memory 24 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the communication method in this embodiment. The processor 22 executes various functional applications and data processing by running the computer program stored in the memory 24, thus implementing the aforementioned method. The memory 24 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 24 may further include memory remotely located relative to the processor 22, and these remote memories can be connected to the mobile terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0033] The transmission device 26 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by the mobile terminal's communication provider. In one example, the transmission device 26 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 26 may be a Radio Frequency (RF) module, used for wireless communication with the Internet.

[0034] In one embodiment of this disclosure, a communication method is provided, applied to a user equipment. Figure 3 is a flowchart (I) of the communication method of the user equipment according to an embodiment of this disclosure. As shown in Figure 3, the process includes the following steps:

[0035] Step S302: Receive a first message sent by the first network element, wherein the first message carries at least one set of waveform configuration information, waveform type, or environmental perception information related to at least one set of waveform configuration information;

[0036] Step S304: Determine a set of waveform configuration information based on the first message;

[0037] Step S306: Based on a set of waveform configuration information, use the corresponding waveform to communicate with the first network element.

[0038] In this embodiment, the first network element can be a base station, a network-side network element, etc.

[0039] In this embodiment, at least one set of waveform configuration information, waveform type, or environmental awareness information carried in the first message is related to a specific new waveform or improved waveform. The first network element can configure the parameters of the new waveform for the user equipment, and the user equipment can use the new waveform to communicate with the first network element, which solves the problem of poor performance of traditional waveforms in uplink and downlink channels in related technologies and achieves the effect of improving spectrum efficiency.

[0040] In this embodiment, the environmental awareness information includes the characteristics of the communication environment. This information can serve as an important basis for waveform selection. The UE or network element can adaptively select an appropriate waveform configuration based on the environmental awareness information, avoiding the performance degradation problem of traditional fixed waveforms in changing communication environments. The environmental awareness information can be obtained not only from the first or second network element, but also determined by the UE itself through environmental awareness.

[0041] In some embodiments, step S304 determines a set of waveform configuration information based on the first message, including at least one of the following:

[0042] Step S304A involves obtaining at least one set of waveform configuration information from the first message and determining one set of waveform configuration information from the at least one set of waveform configuration information. Specifically, after receiving the first message, the user equipment can parse multiple sets of waveform configuration information from the message and then select the most suitable set of waveform configuration information for communication based on its own conditions and environmental awareness information. This method improves the flexibility and efficiency of waveform configuration, enabling the user equipment to select the optimal waveform configuration in different communication scenarios, thereby improving communication quality.

[0043] Step S304B involves obtaining the waveform type from the first message and determining a set of waveform configuration information based on the waveform type. The communication system can simultaneously support multiple waveform types. The user equipment can determine the waveform configuration information matching the received waveform type, combined with its own waveform processing capabilities and / or environmental awareness information. This method ensures that the user equipment can use the most suitable waveform for communication and improves configuration efficiency. The matching relationship between the waveform type and the waveform configuration information can be pre-configured locally on the user equipment or pre-configured through other signaling; this disclosure does not impose any restrictions on this.

[0044] Step S304C involves obtaining environmental awareness information from the first message and determining a set of waveform configuration information based on this information. The user equipment can select the waveform configuration information most suitable for the current environment based on the environmental awareness information to optimize communication performance. This method achieves intelligent waveform configuration by utilizing environmental awareness information, thereby improving the adaptability and efficiency of the communication system. The matching relationship between environmental awareness information and waveform configuration information can be pre-configured locally on the user equipment or pre-configured through other signaling; this disclosure does not impose any restrictions on this.

[0045] In some embodiments, the method further includes: step S302', receiving a second message sent by a second network element, wherein the second message carries at least one set of waveform configuration information, waveform type or environmental awareness information, and the information type or information content carried by the second message is the same as or different from that carried by the first message.

[0046] Steps S302 and S302' can be executed simultaneously or at different times; this disclosure does not impose any restrictions on this.

[0047] In this embodiment, the user equipment not only receives at least one set of waveform configuration information, waveform type, or environmental awareness information from the first network element, but can also receive the above information from the second network element (such as another base station or network-side network element). This increases the sources of waveform configuration information, enabling the user equipment to make more comprehensive waveform configuration selections based on information from multiple network elements, thereby improving communication reliability and enhancing the flexibility and adaptability of the system.

[0048] In an exemplary embodiment, the second message carries the same type of information as the first message, but the information content is different. For example, the first network element and the second network element can each configure a set of waveform configuration information for the user equipment, and the user equipment can choose to communicate based on the waveform corresponding to which set of waveform configuration information.

[0049] In an exemplary embodiment, the second message carries a different type of information than the first message. For example, the first network element may carry multiple sets of waveform configuration information, while the second network element may carry environmental awareness information. The user equipment may select a set of waveform configuration information from the multiple sets of waveform configuration information sent by the first network element based on the environmental awareness information.

[0050] In some embodiments, step S304, determining a set of waveform configuration information based on the first message, may include: determining a set of waveform configuration information based on the first message and / or the second message. The user equipment can synthesize the information in the first and second messages to determine the waveform configuration information. This method ensures the accuracy and comprehensiveness of the waveform configuration, and can achieve better communication performance, especially in scenarios involving multi-network element collaborative communication.

[0051] In some embodiments, the waveform includes one of the following: a first waveform; a second waveform; a third waveform.

[0052] In one exemplary embodiment, the first waveform is a Generalized Filter Bank Orthogonal Frequency Division Multiplexing (GFB-OFDM) waveform.

[0053] In this embodiment, the GFB-OFDM waveform can utilize a two-stage Inverse Fast Fourier Transform (IFFT) and multiple filters to achieve joint processing of multiple subbands / bandwidths / partial bandwidths. This waveform can decompose a large-point IFFT into two stages of smaller-point IFFTs, enabling the completion of the large-point IFFT operation using two stages of smaller-point IFFTs, and can achieve filtering effects for each subband. Furthermore, the GFB-OFDM waveform can be used not only for end-to-end communication but also for broadcasting. The specific implementation of the GFB-OFDM waveform only involves the transmitting end and does not affect the receiving end. That is, the UE can also receive the GFB-OFDM waveform using the traditional OFDM reception method, and it is compatible with the reception of CP-OFDM waveforms. In addition, the GFB-OFDM waveform can also be transmitted and received in the Delay-Doppler (DD) domain. If the UE has the relevant reception capabilities and obtains the relevant configuration, better demodulation performance can be obtained. In particular, if the subband division is small, the performance will be greatly improved by using matched filtering.

[0054] In this embodiment, by using GFB-OFDM waveforms for communication, the problem of performance degradation of traditional OFDM waveforms under discontinuous spectrum conditions can be solved, and the utilization rate of spectrum resources can be improved. Especially in the scenario of spectrum fragmentation, GFB-OFDM waveforms can provide better communication performance.

[0055] In one exemplary embodiment, the second waveform is an Enhanced Discrete Fourier Transform-Spread Orthogonal Frequency Division Multiplexing (E-DFT-s-OFDM) waveform. The E-DFT-s-OFDM waveform inserts a header and tail sequence on each symbol and adds Frequency Domain Spectrum Shaping (FDSS) in the frequency domain. The inserted header and tail sequences are resistant to multipath delay differences, can be flexibly copied from the reference signal symbol, and have variable lengths without affecting the symbol duration. FDSS effectively suppresses interference from the data portion to the tail sequence while reducing PAPR.

[0056] In this embodiment, by using E-DFT-s-OFDM waveforms for communication, the differences in multipath delay can be resisted, the interference of the data portion on the tail sequence can be effectively suppressed, and the PAPR can be reduced. This solves the problem of poor traditional waveform performance of uplink and downlink channels in related technologies and achieves the effect of improving spectral efficiency.

[0057] In one exemplary embodiment, the third waveform is a waveform based on Frequency Domain Spectrum Shaping (FDSS). By combining FDSS with conventional waveforms, spectral leakage can be reduced and spectral efficiency improved. For example, FDSS can be used in uplink DFT-s-OFDM waveform processing to perform designed spectrum shaping on the frequency domain data after the DFT and before the IFFT of the DFT-s-OFDM waveform, thereby reducing the PAPR of the uplink signal.

[0058] In this embodiment, communication is carried out using FDSS-based waveforms. By adjusting the modulation parameters, the signal quality can be maintained while reducing interference to adjacent frequency bands, thereby improving the utilization efficiency of spectrum resources and solving the problem of poor traditional waveform performance in uplink and downlink channels in related technologies.

[0059] In some embodiments, in response to the waveform being a first waveform, each set of waveform configuration information includes at least one of the following:

[0060] The number of subbands, the amount of bandwidth, the amount of partial bandwidth, the amount of sub-bandwidth, or the number of receiving nodes;

[0072] In an exemplary embodiment, if the first waveform is a GFB-OFDM waveform, the number of transform points can be the number of IFFT points, with the first transform being a subcarrier-level IFFT and the second transform being a subband-level IFFT.

[0073] In this embodiment, by dynamically configuring any of the above-mentioned configuration parameters for the user equipment, the user equipment can use a first waveform, such as a GFB-OFDM waveform, for communication, thereby achieving flexible configuration of waveform parameters and improving communication quality by adapting to optimizations in different environments.

By adjusting the frequency domain attributes, efficient utilization of spectrum resources can be achieved, thereby improving the spectrum efficiency of the communication system.

[0076] In some embodiments, the relevant parameters include at least one of the following: subcarrier spacing, index, starting offset of the starting point relative to the reference point, starting resource block, ending resource block, bandwidth, number of resource blocks, and number of resource elements. These relevant parameters define the details of the waveform configuration; by adjusting these parameters, waveform optimization can be achieved, thereby improving communication quality.

[0077] In some embodiments, in response to the waveform being a second waveform, each set of waveform configuration information includes at least one of the following: head sequence length, which may include a start sequence index, an end sequence index, and / or the number of sequences; tail sequence length, which may include a start sequence index, an end sequence index, and / or the number of sequences; one or more alternative values ​​for the head sequence length; one or more alternative values ​​for the tail sequence length; configuration information for a reference signal used to generate the head sequence and / or tail sequence; the number of modulation parameters at the transmitting end, wherein the number of modulation parameters is an integer, such as 1, 2, ..., N; the values ​​of the modulation parameters, wherein the values ​​of each modulation parameter are real numbers, such as 0.5, 1, 2, etc.; and the index of the modulation parameter. For example, the modulation parameter may be an FDSS modulation parameter.

[0078] In an exemplary embodiment, the sequence length can be represented by the number of sequences or by time, such as in microseconds (µs), or by DFT points, or by a proportion, such as the proportion occupying one symbol length.

[0079] In one exemplary embodiment, the length of the header sequence and / or tail sequence is related to the bandwidth, and / or the channel environment, and / or the multipath delay spread, and / or the subcarrier spacing, and / or the bandwidth / number of reference signals. That is, when determining the length of the header sequence and / or tail sequence, the UE / first network element / second network element can determine it based on at least one of the following: bandwidth, channel environment, multipath delay spread, subcarrier spacing, reference signal bandwidth, number of reference signals, etc.

[0080] In an exemplary embodiment, the base station may send one or more sets of the above-described configuration information to the UE. Each set of configuration information may be associated with a configuration ID, beam direction, start time, end time, and / or duration. The configuration ID is an integer; the start and end times may include SFN index, slot index, frame number index, subframe number index, and / or OFDM symbol index; the duration may include the number of SFNs, slots, frames, subframes, and / or OFDM symbols, and may also be in units such as seconds or milliseconds. The beam direction may be represented by a beam index or angle, indicating that the UE uses the corresponding waveform configuration in certain specific beam directions.

[0081] In one exemplary embodiment, the length units of the head sequence and the tail sequence may be the same or different units.

[0082] In one exemplary embodiment, downlink information such as DCI and / or RRC signaling may carry alternative values ​​for header and / or tail sequence lengths, i.e., one or more header / tail sequence lengths, or a combined length of one or more header and tail sequences. For example, the header sequence length may be configured as {H1, H2, H3, ..., HN}, the tail sequence length may be configured as {T1, T2, T3, ..., TN}, and the combined header and tail sequence may be configured as {{H1, T2}, {H2, T2}, {H3, T3}, ..., {HN, TN}}.

[0083] In one exemplary embodiment, the UL / DL MAC CE may also carry a suggested / configured header and / or tail sequence length.

[0084] In this embodiment, by dynamically configuring any of the above-mentioned configuration parameters for the user equipment, the user equipment can use a second waveform, such as an E-DFT-s-OFDM waveform, for communication, thereby optimizing the signal spectrum and improving the spectral efficiency of the communication system. The configuration of alternative values ​​can improve the flexibility and adaptability of communication; the user equipment can select the most suitable sequence length from the alternative values ​​based on the communication environment or its own circumstances.

[0085] In some embodiments, the configuration information of the reference signal includes at least one of the following: the sequence number of the reference signal, the sequence length of the reference signal, the initialization sequence type of the reference signal, the sequence generation method of the reference signal (e.g., ZC sequence / low-PAPR sequence, gold sequence), the initialization sequence length of the reference signal, the ID of the transmitting node, the time domain resources where the reference signal is located (including period, start time, end time and / or duration), the frequency domain resources where the reference signal is located (including frequency domain start position, frequency domain end position and / or number of RBs), the comb size of the reference signal, and / or the offset. Optionally, the above configuration can be a suggested configuration sent by the core network / LMF / SF / UE to the base station. The base station then sends waveform configuration to the UE according to the configuration suggestion from the core network / LMF / SF / UE, and the UE sends uplink signals according to the base station's configuration. The configuration information of the reference signal defines the generation method of the reference signal and is an important component of the e-DFT-s-OFDM waveform configuration. By adjusting the configuration information of the reference signal, signal optimization can be achieved, and communication quality can be improved.

[0086] In some embodiments, the UE may send its suggested and / or capability information to the network or base station, including at least one of the following: a 1-bit indication of whether the waveform is supported, the supported and / or suggested header sequence length, or maximum / minimum / length range, the supported and / or suggested tail sequence length, or maximum / minimum / length range, the combined / integrated lengths of the supported and / or suggested header and tail sequences, the supported and / or suggested reference signal (sequence) length, the supported and / or suggested initialization sequence type, the supported and / or suggested initialization sequence length, the time domain resources where the supported and / or suggested reference signal resides, including period, start time, end time and / or duration, the frequency domain resources where the supported and / or suggested reference signal resides, including frequency domain start position, frequency domain end position and / or number of RBs, the comb configuration combsize and / or offset of the supported and / or suggested reference signal, and the sequence generation method of the supported and / or suggested reference signal. Through the above methods, the core network / base station / UE can coordinate the relevant configurations of the uplink waveform, select an appropriate waveform configuration for transmission, and improve system performance.

[0087] In some embodiments, in response to the waveform being a third waveform, each set of waveform configuration information includes at least one of the following: the number of modulation parameters at the transmitting end; and the values ​​of the modulation parameters.

[0088] In the embodiments of this disclosure, the modulation parameters may include, but are not limited to, FDSS modulation parameters.

By dynamically adjusting the number and values ​​of the modulation parameters corresponding to the newly added modulation method, dynamic adjustment of the waveform can be achieved, thereby improving communication performance.

[0089] In some embodiments, at least one set of waveform configuration information is determined by the first network element or the second network element based on at least one of the following: waveform capability information of the user equipment; waveform configuration information proposed by the user equipment; synchronization signal block information measured by the user equipment; channel state information measured by the user equipment; and environmental awareness information of the user equipment.

[0090] In this embodiment, one or more of the above information can be set as important bases for determining waveform configuration information according to the communication environment and the hardware / software capabilities of the device. By dynamically configuring waveform parameters based on this information by the first network element or the second network element, waveform optimization can be achieved and communication quality can be improved.

[0091] In some embodiments, the environmental perception information includes at least one of the following: delay spread parameters, perceived environmental parameters, line-of-sight (LOS) indication, and non-line-of-sight (NLOS) indication.

[0093] In this embodiment, waveform capability information is the basis for waveform configuration negotiation between user equipment and network element. By providing this information, network element can understand the waveform processing capability of user equipment, thereby configuring the most suitable waveform parameters for user equipment, improving communication efficiency and quality.

[0094] In some embodiments, the environmental awareness information of the user equipment is obtained by the first network element, the second network element, or the user equipment through environmental sensing. Environmental awareness information, such as delay spread parameters and perceived environmental parameters, is a crucial basis for determining waveform configuration. By sensing the environment through the first network element, the second network element, or the user equipment, real-time environmental information can be obtained, thereby configuring waveform parameters most suitable for the current environment, improving the adaptability and efficiency of communication.

[0095] In some embodiments, the first network element includes one of the following: a base station, a transmission and reception point (TRP), a sensing function (SF) network element, and a location management function (LMF) network element; the second network element includes at least one of the following: a base station, a transmission and reception point, a sensing function network element, and a location management function network element, and the second network element is different from the first network element.

[0096] In this embodiment, the first network element and the second network element can be different functional entities in the communication system. Their information interaction and waveform configuration coordination can achieve more comprehensive environmental perception and more optimized waveform configuration, thereby improving the overall performance of the communication system.

[0097] In an exemplary embodiment, the TRP may first send configuration suggestions (i.e., at least one set of waveform configuration information) or waveform type or environment awareness information to the SF / LMF, and then the SF / LMF sends configuration (i.e., the final determined set of waveform configuration information) to the UE.

[0098] In an exemplary embodiment, the SF / LMF may first send configuration suggestions or waveform type or environment-aware information to the TRP, and then the TRP sends the configuration to the UE.

[0099] In one exemplary embodiment, the SF / LMF may first send configuration suggestions, waveform type, or environment-aware information to the UE, and then the UE may decide on the configuration itself.

[0100] In some embodiments, taking the first network element as a base station as an example, the first message may be carried in at least one of the following: Downlink Control Information (DCI); Physical Downlink Control Channel configuration (PDCCH-config) message; Radio Resource Control (RRC) message; Downlink Medium Access Control Element (DLMAC CE).

[0101] In other embodiments, if the second network element is a base station, the second message may also be carried in at least one of the following: DCI, UCI, PDCCH-config message, RRC message, DLMAC CE, etc.

[0102] In this embodiment, the user equipment can receive the aforementioned waveform configuration information, waveform type, or environment awareness information through various messages in the existing standard protocol, improving the flexibility of waveform configuration. Furthermore, information interaction between the UE and SF / LMF network elements, and between the base station and SF / LMF network elements, can be implemented according to the relevant provisions in the existing and future standard protocols. Since the message names are not yet clearly defined in the current standards, no specific limitations are made here.

[0103] In other embodiments, in existing NR protocols, Uplink Control Information (UCI) is sent by the User Equipment (UE) to the base station (e.g., eNodeB in LTE, gNodeB in 5G). UCI contains various types of signals and information, primarily including:

[0104] 1) Hybrid Automatic Repeat Request Acknowledgment / Nack (HARQ ACK / NACK): Used to acknowledge or deny whether the data sent by the base station has been successfully received.

[0105] 2) Channel Quality Indicator (CQI): After the UE measures the downlink channel quality, it feeds it back to the base station to help the base station determine the modulation and coding scheme (MCS) for subsequent data transmission.

[0106] 3) Precoding Matrix Indicator (PMI) and Rank Indicator (RI): Used in multi-antenna systems, the UE feeds back channel state information to guide the base station in precoding and spatial multiplexing.

[0107] 4) Scheduling Request (SR): Sent by the UE when requesting uplink resources.

[0108] In some embodiments, through UCI, the UE can also feed back necessary control information to the base station, enabling the base station to optimize resource allocation and data transmission strategies, thereby improving communication efficiency and user experience. This disclosure can also use UCI to enable the exchange of control information such as waveform configuration information, waveform type, and environmental awareness information between the UE and the base station.

[0109] In one exemplary embodiment, in an LTE and 5G system, the base station (eNodeB or gNodeB) can configure uplink resources for the UE through specific signaling and channels, including:

[0110] 1) DCI; The base station can send the DCI to the UE via PDCCH (Physical Downlink Control Channel). The DCI contains the Uplink Grant, which specifies the time and frequency band range in which the UE can use uplink resource blocks, and may contain key parameters such as modulation and coding scheme (MCS) and HARQ process information.

[0111] 2) RRC signaling; In addition to immediate uplink authorization, the base station can also configure longer-term parameters via RRC signaling, such as uplink transmit power control settings, CQI reporting period, and uplink control information format. These configurations are typically sent to the UE via RRC Connection Reconfiguration messages when establishing a connection or changing the connection state.

[0112] In this embodiment, the base station can dynamically control and adjust the uplink resource allocation of the UE through DCI or RRC signaling, so as to ensure the effective utilization of network resources and the optimization of communication quality.

[0113] In this embodiment, intelligent and adaptive communication waveforms are achieved through dynamic configuration of waveform parameters, improving the flexibility, adaptability, and efficiency of the communication system. This disclosure proposes using new waveforms for uplink and downlink communication and refines the protocol details for waveform configuration, which can address the performance issues present in traditional waveforms, improving communication performance and spectrum utilization efficiency. Through information interaction between user equipment and network elements, collaborative optimization of waveform configuration is achieved, further enhancing the overall performance of the communication network.

[0114] In another embodiment of this disclosure, a communication method is also provided, applied to a user equipment. Figure 4 is a flowchart (II) of a communication method for a user equipment according to an embodiment of this disclosure. As shown in Figure 4, the process includes the following steps:

[0115] In step S402, the user equipment sends a third message to the first network element and / or the second network element.

[0116] The third message includes at least one of the following: waveform capability information of the user equipment; waveform configuration information suggested by the user equipment; synchronization signal block (SSB) information measured by the user equipment; channel state information (CSI) measured by the user equipment; and environmental awareness information measured by the user equipment.

[0117] In this embodiment, the UE can periodically report the third message or report the third message according to the control command.

[0118] In this embodiment, the sending of the third message is an important step in the waveform configuration negotiation between the user equipment and the network element. By sending these messages to the network element, the user equipment can participate in the dynamic configuration process of waveform parameters, and the network element can select more suitable waveform configuration parameters based on the information reported by the user equipment, thereby improving the adaptability and efficiency of communication.

[0119] In some embodiments, the first network element includes one of the following: base station, TRP, SF network element, LMF network element; the second network element includes at least one of the following: base station, TRP, SF network element, LMF network element, and the second network element is different from the first network element.

[0120] In some embodiments, the information type or information content carried in the third message sent by the user equipment to the first network element and the second network element may be the same or different.

[0121] In some embodiments, the third message is used to (assist the first network element and / or the second network element) determine at least one set of waveform configuration information or waveform type. For example, if the third message contains waveform capability information of the user equipment, the network element can recommend at least one set of waveform configuration information to the UE based on the waveform capability information of the user equipment, thereby realizing communication waveform configuration. The specific content of the waveform configuration information can be referred to the relevant descriptions in the preceding embodiments, and will not be repeated here.

[0122] In some embodiments, the first network element and / or the second network element may determine whether to configure / adjust the waveform of the UE according to a preset rule based on the third message. If it is determined that the waveform of the UE should be configured / adjusted, the process on the user equipment side can refer to the above embodiments (such as steps S302 to 306). The user equipment receives the first message from the first network element and / or the user equipment receives the second message from the second network element, thereby completing the reception of waveform configuration-related information.

[0123] In some embodiments, after receiving the third message, the first network element and / or the second network element may determine that waveform configuration / adjustment for the UE is not required. In this case, the first network element and / or the second network element may not perform any further processing on the third message. For example, the first network element may have previously configured the waveform for the UE based on the UE's environmental awareness information, and the latest received environmental awareness information is not significantly different from the previous information. Therefore, the first network element determines that the previous waveform configuration can continue to be used for communication, and in this case, the first network element does not reissue the configuration.

[0124] In this embodiment of the disclosure, the preset rules for the first network element and / or the second network element to determine whether to configure / adjust the waveform of the UE can be adjusted according to actual needs. For example, it can be set that the configuration is re-performed when the change in the environmental perception information reaches a certain threshold, or it can be set that when a certain parameter exceeds a reasonable range, the reported parameter may be abnormal, and all or part of the content of the third message reported this time is directly regarded as invalid. This disclosure does not limit the specific content of the preset rules.

[0125] In some embodiments, the waveform involved in the waveform capability information and waveform configuration information may include one of the following: a first waveform; a second waveform; and a third waveform. For example, the first waveform may be a GFB-OFDM waveform, the second waveform may be an E-DFT-s-OFDM waveform, and the third waveform may be an FDSS-based waveform, but this disclosure is not limited thereto.

[0126] In some embodiments, the waveform capability information of the user equipment includes at least one of the following: indication information indicating whether the user equipment supports processing a first waveform, a second waveform, and / or a third waveform; waveform types that the user equipment supports processing; configuration information of the first waveform supported by the user equipment; configuration information of the second waveform supported by the user equipment; and configuration information of the third waveform supported by the user equipment.

[0127] In this embodiment, different UEs may have different processing capabilities for waveforms such as GFB-OFDM. For example, some UEs only support traditional waveforms (such as CP-OFDM) processing and do not support new waveforms (such as GFB-OFDM) processing. Therefore, waveform capability information is the basis for waveform configuration negotiation between user equipment and network elements. By providing this information, network elements can understand the waveform processing capabilities of user equipment and configure the waveform parameters most suitable for user equipment, thereby improving the efficiency and quality of communication.

[0128] In one exemplary embodiment, if the waveform is a GFB-OFDM waveform, the waveform capability information reported by the UE may include at least one of the following:

[0129] Indicates whether the user equipment supports processing GFB-OFDM waveforms (1-bit indication information);

[0130] Supported number of processing points (Fast Fourier Transform (FFT));

[0131] Number of supported subbands;

[0132] Supported number of first-level (FFT) processing points;

[0133] Number of supported second-order (FFT) processing points;

[0134] Supported subband width (in bandwidth or in resource blocks (RBs));

[0135] Supported sub-band start and / or sub-band end positions;

[0136] Supported subband subcarrier spacing.

[0137] In this embodiment of the disclosure, waveform capability information of other waveforms can be reported by selecting one or more of them with reference to waveform configuration information, which will not be elaborated here.

[0138] In an exemplary embodiment, if the waveform is a GFB-OFDM waveform, the suggested waveform configuration information reported by the UE may include at least one of the following:

[0139] Recommended number of FFT processing points;

[0140] Suggested number of sub-bands;

[0141] Recommended number of FFT processing points for Level 1;

[0142] Recommended number of FFT processing points;

[0143] Recommended subband width (in bandwidth or in RB);

[0144] Suggested sub-band start and / or end positions;

[0145] Recommended subband subcarrier spacing.

[0146] The aforementioned capability information and / or suggestion reporting can be linked to time information, indicating that the UE has the corresponding capability or configuration suggestion within the corresponding time period. One or more sets of capabilities and / or suggestions can be configured, with different configurations associated with different time periods. This method better coordinates the dynamic nature of UE capabilities and suggestions, allowing the UE to dynamically adjust based on the environment or its equipment. If the UE reports a corresponding capability and / or suggestion at a certain time, but the UE's capabilities and / or suggestions change at another time, the UE can send a 1-bit indication to the network that the previous capabilities and / or suggestions are no longer available, or directly send the updated capabilities and / or suggestions.

[0147] In another exemplary embodiment, the waveform capability information of the user equipment corresponding to the second waveform includes at least one of the following: indication information indicating whether the user equipment supports processing the second waveform; supported header sequence length / maximum length / minimum length / length range; supported tail sequence length / maximum length / minimum length / length range; supported header and tail sequence length combination / combination; supported reference signal sequence length; supported initialization sequence type; supported initialization sequence length; supported time-domain resources of the reference signal; supported frequency-domain resources of the reference signal; supported comb configuration and / or offset of the reference signal; and supported sequence generation method of the reference signal.

[0148] In another exemplary embodiment, the waveform configuration information suggested by the user equipment corresponding to the second waveform includes at least one of the following: suggested header sequence length / maximum length / minimum length / length range; suggested tail sequence length / maximum length / minimum length / length range; suggested header and tail sequence length combination / combination; suggested reference signal sequence length; suggested initialization sequence type; suggested initialization sequence length; suggested time domain resources of the suggested reference signal; suggested frequency domain resources of the suggested reference signal; suggested comb configuration combsize and / or offset of the suggested reference signal; suggested sequence generation method of the suggested reference signal.

[0149] In another exemplary embodiment, the waveform capability information of the user equipment corresponding to the third waveform includes at least one of the following: indication information indicating whether the user equipment supports processing the third waveform; indication information indicating whether the user equipment has frequency domain spectrum shaping (FDSS) processing capability; the number of supported modulation parameters; the values ​​of the supported modulation parameters; the index of the supported modulation parameters; and the supported modulation type.

[0150] In another exemplary embodiment, the waveform configuration information suggested by the user equipment corresponding to the third waveform includes at least one of the following: the number of suggested modulation parameters; the values ​​of the suggested modulation parameters; the index of the suggested modulation parameters; and the suggested modulation type.

[0151] Through the above embodiments, the configuration and reporting of new waveforms can be achieved at the standard level. In the embodiments of this disclosure, the UE can report suggested waveform configuration information based on its own capabilities or UE-measured CSI / SSB / environmental awareness information, etc. This disclosure is not limited to GFB-OFDM waveforms; suggested configuration information for other waveforms can be selected from the waveform configuration information of the corresponding waveforms described above for suggested reporting, which will not be elaborated further here.

[0152] In some embodiments, the information in the third message can be measured by the UE itself, or it can be measured by the base station, SF, or LMF network elements, and the network element being measured is different from the network element reported by the UE. For example, the UE can obtain its own environmental awareness information through the SF network element, and then the UE reports the environmental awareness information to the base station through the third message. Finally, the base station configures the UE's waveform based on the environmental awareness information.

[0153] Through the embodiments of this disclosure, the user equipment can participate in the dynamic configuration process of waveform parameters, providing key reference information related to waveform configuration to the network element before the network element performs waveform configuration, thereby improving the adaptability and efficiency of communication. Through information interaction and waveform configuration coordination among the first network element, the second network element, and the UE, more comprehensive environmental awareness and more optimized waveform configuration can be achieved, improving the overall performance of the communication system.

[0154] In another embodiment of this disclosure, a communication method is also provided, applied to a first network element. Figure 5 is a flowchart (I) of the communication method of the first network element according to an embodiment of this disclosure. As shown in Figure 5, the process includes the following steps:

[0155] In step S502, the first network element receives the fourth message from the second network element.

[0156] The fourth message carries at least one set of waveform configuration information, waveform type, or environmental awareness information related to at least one set of waveform configuration information.

[0157] In this embodiment, the first network element includes one of the following: base station, TRP, SF network element, LMF network element; the second network element includes at least one of the following: base station, TRP, SF network element, LMF network element, and the second network element is different from the first network element.

[0158] In some embodiments, step S502 can be implemented independently. For example, after receiving the fourth message, the first network element can perform a preliminary judgment on the information carried by the fourth message according to preset rules to determine whether subsequent waveform configuration / adjustment procedures are needed. For instance, if the value of the information received by the first network element from the second network element is significantly abnormal or changes only slightly compared to the previously received information, then the waveform configuration / adjustment procedure can be discontinued. The waveform configuration / adjustment procedure can refer to the waveform configuration procedure in the preceding embodiments.

[0159] In some embodiments, step S502 can be implemented in conjunction with the user equipment side method embodiments described above. Furthermore, the information type or content carried in the fourth message may be the same as or different from that carried in the first message in the above embodiments.

[0160] In an exemplary embodiment, if the first message and the fourth message carry the same information type and information content, then the first network element can directly transmit the information in the fourth message to the user equipment after receiving the fourth message (i.e., step S302, the user equipment receives the first message from the first network element).

[0161] In another exemplary embodiment, the first message and the fourth message carry different types of information. For example, the first network element first receives the fourth message carrying environmental awareness information from the second network element, determines at least one set of waveform configuration information based on the environmental awareness information, and then sends the first message carrying at least one set of waveform configuration information to the user equipment. Any other combination of different message types can be implemented in the first message and the fourth message, and this disclosure does not limit this.

[0162] In another exemplary embodiment, the first message and the fourth message carry the same type of information, but different content. For example, the first network element first receives the fourth message carrying at least one set of waveform configuration information from the second network element, selects a portion of the waveform configuration information from the at least one set of waveform configuration information, and sends the first message carrying the selected waveform configuration information to the user equipment. Information transmission and selection processes for other information types can also be implemented in the first and fourth messages, and this disclosure does not limit this process.

[0163] This disclosure enables information exchange between a first network element and a second network element in a new waveform configuration process, improving the communication and waveform configuration processes and filling gaps in current communication standard protocols. In this embodiment, the first and second network elements can exchange information on at least one set of waveform configuration information, waveform type, or environmental awareness information related to at least one set of waveform configuration information for a specific waveform. This achieves information sharing and waveform configuration coordination between network elements, improving the overall performance of the communication system.

[0164] In some embodiments, the method further includes the following steps:

[0165] In step S504A, in response to the fourth message carrying environmental awareness information, the first network element determines at least one set of waveform configuration information based on the environmental awareness information.

[0166] In step S504B, in response to the fourth message carrying at least one set of waveform configuration information, the at least one set of waveform configuration information is determined by the second network element based on the environmental perception information.

[0167] In this embodiment, the waveform configuration information is determined based on environmental perception information. This method can improve the matching degree and adaptability of communication waveform configuration with environmental changes. However, the entity settings used to determine the waveform configuration information in this disclosure are relatively flexible and can be implemented on the first network element and the second network element. Furthermore, in conjunction with the previous user equipment side embodiment, the waveform configuration information can also be determined by the user equipment itself. This disclosure does not impose any restrictions on this.

[0168] In some embodiments, environmental awareness information may include at least one of the following: delay spread parameters, perceived environment parameters, line-of-sight (LOS) indication, non-line-of-sight (NLOS) indication, etc.

[0169] Through the embodiments of this disclosure, a more flexible and diversified way of obtaining waveform configuration information and other related information of user equipment is provided. Not only can the user equipment and the first network element cooperate to perform waveform configuration, but the first network element, the second network element and the user equipment can also cooperate. That is, the sharing of environmental perception information and waveform configuration cooperation are realized among the user equipment, the base station and the network-side network element, thereby improving the overall performance of the communication system.

[0170] In another embodiment of this disclosure, a communication method is also provided, applied to a first network element. Figure 6 is a flowchart (II) of the communication method of the first network element according to an embodiment of this disclosure. As shown in Figure 6, the process includes the following steps:

[0171] Step S602: The first network element sends a first message to the user equipment;

[0172] In step S604, the first network element determines a set of waveform configuration information based on the first message, and communicates with the user equipment using the corresponding waveform based on the set of waveform configuration information.

[0173] The first message carries at least one set of waveform configuration information, waveform type, or environmental awareness information related to at least one set of waveform configuration information.

[0174] In this embodiment, steps S602 to S604 correspond to steps S302 to S306 in the user equipment side embodiment. Specifically, the first network element and the user equipment can determine the waveform configuration information to be used based on the same information content and the same waveform information determination rules (such as the same information mapping relationship). Alternatively, either the first network element or the user equipment can determine the final waveform configuration information to be used, and then synchronize the configuration information through signaling interaction.

[0175] In this embodiment, the first network element includes one of the following: base station, TRP, SF network element, LMF network element.

[0176] In some embodiments, the waveform used in step S604 may include one of the following: a first waveform; a second waveform; or a third waveform. For example, the first waveform may be a GFB-OFDM waveform, the second waveform may be an E-DFT-s-OFDM waveform, and the third waveform may be an FDSS-based waveform, but this disclosure is not limited thereto.

[0177] In this embodiment, at least one set of waveform configuration information, waveform type, or environmental awareness information carried in the first message is related to a specific new waveform or improved waveform. The first network element can configure the parameters of the new waveform for the user equipment, and the user equipment can use the new waveform to communicate with the first network element, which solves the problem of poor performance of traditional waveforms in uplink and downlink channels in related technologies and achieves the effect of improving spectrum efficiency.

[0178] According to the various embodiments of this disclosure, the communication method provided by this disclosure achieves intelligent and adaptive communication waveforms through dynamic configuration of waveform parameters, thereby improving the flexibility, adaptability, and efficiency of the communication system. Particularly in the field of wireless communication, this method can significantly improve communication quality and efficiency, reduce signal interference, and enhance system robustness and user equipment communication experience. Through information interaction between user equipment and network elements, collaborative optimization of waveform configuration is achieved, further improving the overall performance of the communication network. The technical solution of this invention is not only applicable to current communication systems, but also includes, but is not limited to, future 5G and 6G communication networks, as well as communication optimization in various IoT and vehicle-to-everything (V2X) scenarios, possessing broad application prospects and value.

[0179] In an exemplary embodiment of this disclosure, the user equipment and the first network element communicate using a GFB-OFDM waveform. The GFB-OFDM waveform utilizes a two-stage IFFT and a polyphase filter to achieve joint processing of multiple subbands / bandwidths / partial bandwidths. This waveform can decompose a large-point IFFT into two stages of small-point IFFTs. Furthermore, the GFB-OFDM waveform is primarily used for downlink communication. Compared to the CP-OFDM waveform used in traditional downlink communication, the GFB-OFDM waveform can reduce computational complexity and improve system performance when processing high-bandwidth signals, while maintaining compatibility with existing CP-OFDM waveforms. The GFB-OFDM waveform can reduce the impact of multipath delay through subband-level processing and filter design. Therefore, compared to CP-OFDM, it allows for shorter CPs, thereby reducing CP overhead and improving spectral efficiency. Moreover, the configuration parameters of the GFB-OFDM waveform, such as the number and width of subbands and subcarrier spacing, can be dynamically configured according to different channel environments and multipath delays, thereby achieving better performance.

[0180] Figure 7 is a technical principle block diagram of the first waveform transmitting end in an embodiment of this disclosure. As shown in Figure 7, the generation of the first waveform (such as a GFB-OFDM waveform) requires the following processing flow:

[0181] S1, divide the coded and modulated data to be transmitted into multiple groups of data (multiple sub-bands);

[0182] S2, perform IFFT (first-level IFFT or subcarrier-level IFFT) on each group of data, where the number of points in the first-level IFFT is related to the number of subcarriers in each subband;

[0183] S3, perform subband-level IFFT transformation (two-level IFFT) on the subcarrier-level IFFT data of each subband together, where the number of points in the two-level IFFT is related to the number of subbands;

[0184] S4, after being processed by a multiphase filter, transmits data after being processed by the Digital-to-Analog Converter (DAC) module and the Radio Frequency (RF) module.

[0185] In the above process, the subband partitioning process and the subcarrier-level IFFT together are called the subcarrier-level processing module, while the subband-level IFFT and the polyphase filtering process together are called the subband-level processing module. By using the subcarrier-level processing module and the subband-level processing module, the operation process of a large-point IFFT can be completed using two levels of IFFT with a smaller number of points, and filtering effects can be achieved for each subband.

[0186] Figure 8 is a schematic diagram of the flow from user equipment accessing the system to receiving data in an embodiment of this disclosure. As shown in Figure 8, under normal circumstances, the terminal (such as UE) needs to go through the following process from accessing the system to receiving data:

[0187] The UE scans the Synchronization Signal Block (SSB) broadcast by the base station. The SSB contains Physical Broadcast Channel (PBCH) information. The PBCH information carries Master Information Block (MIB) parameters. The MIB parameters contain the Physical Downlink Control Channel (PDCCH) configuration information PDCCH-configSIB1 of System Information Block Type 1 (SIB1). PDCCH-configSIB1 contains the location of Control Resource Set CORESET 0 and Search Space 0. The time-frequency domain location of CORESET 0 can be obtained through the configuration parameters of CORESET 0 and Search Space 0. The UE can obtain the location of the PDCCH candidate based on CORESET 0, and further obtain a specific downlink control information type 1_0 (DCI 1_0). Demodulating the DCI yields the location of the Physical Downlink Shared Channel (PDSCH). This PDSCH contains SIB1. After the UE decodes SIB1, it can establish an RRC connection and then obtain RRC messages, such as the PDCCH-config common message. This message contains the locations of other CORESETs and the search space. Similar to the previous process, the UE obtains the location of the PDCCH candidate based on the configuration, demodulates the DCI, and obtains the PDSCH data.

[0188] In this embodiment, broadcast information can also use GFB-OFDM waveforms. The specific implementation method does not affect the receiver; that is, the UE can also receive GFB-OFDM waveforms using traditional OFDM reception methods, thus achieving compatibility with CP-OFDM waveform reception. Furthermore, GFB-OFDM waveforms can also be transmitted and received in the DD domain, i.e., the delay-Doppler domain. If the UE has the relevant reception capabilities and configuration, better demodulation performance can be achieved. In particular, if the subband division is small, matched filtering will provide a greater performance improvement.

[0189] In one exemplary embodiment, the UE can obtain configuration information of the GFB-OFDM waveform from the DCI message in Figure 8, and use the GFB-OFDM waveform in the acquisition of PDSCH data after the DCI message. This embodiment is not limited to the configuration and use of the GFB-OFDM waveform; the configuration and use of the E-DFT-s-OFDM waveform or the FDSS-based waveform can also be implemented in the above message.

[0190] In one exemplary embodiment, the UE can obtain the configuration information of the GFB-OFDM waveform from the PDCCH-config common message in Figure 8, and obtain the control resource set x (CORESET x) and search space x through the GFB-OFDM waveform after the PDCCH-config common message. This embodiment is not limited to the configuration and use of the GFB-OFDM waveform; the configuration and use of the E-DFT-s-OFDM waveform or the FDSS-based waveform can also be implemented in the above message.

[0191] In some embodiments, the DL MAC CE can notify the UE of the activated waveform configuration. The DL MAC CE can be dynamically adjusted, or a timer can be added to the DL MAC CE. The activated configuration is used before the timer expires, and the default configuration can be restored after the timer ends or expires. The start time of the timer can be the time when the UE receives this message. The default configuration can be a 5G waveform configuration or a configuration from a new waveform. The default configuration can be notified by a configuration index. For example, in a data transmission, the base station simultaneously sends downlink signals to four UEs using a first waveform. The specific subband configuration is sent to the four UEs in the downlink information, where subband 1 carries the signal sent to UE1, subband 2 carries the signal sent to UE2, subband 3 carries the signal sent to UE3, and subband 4 carries the signal sent to UE4. Then, the subband index indicated in the DL MAC CE sent to UE2 is 2, or 2 bits - 01; the subband index indicated in the DL MAC CE sent to UE4 is 4, or 2 bits - 11.

[0192] In one exemplary embodiment, the configuration information of the GFB-OFDM waveform can also be configured simultaneously with CORESET x and search space x.

[0193] Alternatively, they can be configured in the same IE. The waveforms of both PDCCH and PDSCH can use GFB-OFDM.

[0194] In an exemplary embodiment, when the UE receives the configuration of the GFB-OFDM waveform, it needs to know the relevant configuration information to obtain the corresponding waveform configuration information and perform related demodulation according to the configuration information to obtain the data sent by the base station to the UE. When the base station or network sends data to the UE, it may indicate or configure at least one of the following GFB-OFDM waveform configuration information:

[0195] 1) Subband / bandwidth / partial bandwidth / number of subbands / number of receiving nodes, where each subband needs to undergo IFFT transformation, and this IFFT transformation is a subcarrier-level IFFT transformation.

[0196] For example, the number of sub-bands can be set to any integer between 1 and 16, as shown in the following configuration.

[0197] num-of-subband INTEGER(1..16)

[0198] 2) Frequency domain attributes of each sub-band / bandwidth / partial bandwidth / sub-bandwidth:

[0199] (1) Start RB index, end RB index, bandwidth, offset of the start point relative to a reference point, number of RBs, subcarrier spacing (if the subcarrier spacing of different subbands is the same, they can be configured at the same time; otherwise, they can be configured separately).

[0200] (2) The reference point can be a predefined frequency domain location, the location of point A, or the zero-frequency center of the system;

[0201] (3) The offset is in RB units.

[0202] For example, the size of the subband configuration list sequence can be set to any integer between 1 and the maximum number of subbands, and the specific content of the sequence can be set to include the subband index (value range 1 to 16), the starting RB index, the ending RB index, the starting RB offset, the number of RBs, the reference point, etc., as shown in the following configuration.

[0203] (4) The starting RB of the first sub-band and the number of RBs in each sub-band can be configured by using this method to calculate the start and end positions of each sub-band from [starting RB + number of RBs in each sub-band * sub-band index].

[0204] (5) Predefined sub-band frequency domain rules: the starting RB, center RB, or ending RB of the first sub-band is the zero-frequency center of the system, and the starting / ending positions of the remaining sub-bands can be calculated by the number of RBs in each sub-band.

[0205] (6) The number of REs in the subband division can be an integer multiple of the FFT points, or it can be a non-integer multiple of the IFFT size. If it is not an integer multiple of the FFT points, zero-padding can be performed at both ends.

[0206] 3) Waveform type for each subband, such as Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM), Filtered-OFDM (F-OFDM), Windowed-OFDM (W-OFDM), Filtered Bank OFDM (FB-OFDM), Orthogonal Time Frequency Space (OTFS) modulation, Orthogonal Code Division Multiplexing (OCDM), etc.

[0207] 4) Relevant parameters of the current subband / bandwidth / partial bandwidth / subbandwidth: such as subcarrier spacing, index, offset of the starting point relative to the reference point, starting RB, ending RB, bandwidth, number of RBs, number of REs.

[0208] 5) Transmitter filter length, which can be expressed in terms of the number of points, the number of sampling points, or the length of time.

[0209] 6) The filter's roll-off factor or roll-off coefficient and / or the filter type, such as a raised cosine filter.

[0210] 7) The number of FFT points at the transmitting end, including the number of first-level FFT points and / or the number of second-level FFT points.

[0211] 8) The starting system frame number (SFN), slot index, and / or OFDM symbol index of the transmitted waveform.

[0212] 9) The end system frame number (SFN), slot index, and / or OFDM symbol index of the transmitted waveform.

[0213] 10) The duration of the transmitted waveform, including the number of SFNs, the number of time slots, the number of OFDM symbols, the number of frames and / or the number of subframes, or in seconds or milliseconds.

[0214] The above configurations can be divided into three categories: frequency domain configuration, time domain configuration, and other configurations at the transmitting end. Frequency domain configuration includes the waveform's configuration in the frequency domain, time domain configuration includes the waveform's configuration in the time domain, and other configurations include related configurations such as transmitting end filters and FFT. The receiving end needs to obtain the transmitting end's filter configuration in order to receive the corresponding signal using the corresponding receiving method. In an exemplary embodiment, the network can also indicate the subband index corresponding to the current UE to the UE in the DL MAC CE, the range of which can be (0..maxsubband-1), occupying log2(maxsubband) bits.

[0215] The above information can be sent from the core network to the base station, and the base station will determine the waveform configuration information based on the recommendations / suggestions of the core network.

[0216] Figure 9 is a schematic diagram illustrating the meaning of waveform configuration information of the first waveform in an embodiment of the present disclosure. As shown in Figure 9, the parameters in the waveform configuration information of the first waveform (such as a GFB-OFDM waveform) can be combined with each other to jointly indicate the frequency domain position of each sub-band in the GFB-OFDM waveform and the frequency domain position of multiple RBs in each sub-band.

[0217] In another exemplary embodiment of this disclosure, the user equipment and the first network element communicate using E-DFT-s-OFDM waveforms, particularly using E-DFT-s-OFDM waveforms for uplink communication, to address the following problems caused by using conventional DFT-s-OFDM waveforms for uplink channel communication: To estimate phase noise, each DFT-s-OFDM symbol needs to be inserted with a PTRS. As the carrier frequency increases, the subcarrier spacing also increases, meaning the duration of each symbol becomes shorter (especially for the THz band). Therefore, the load on CP and PTRS may increase, further reducing spectral efficiency.

[0218] While some new waveforms have been proposed in related technologies, such as Guard Interval DFT-S-OFDM (GIDFT-S-OFDM) and Unique Word DFT-S-OFDM (UW DFT-S-OFDM), the CP (Content Continuity) in these two waveforms is replaced by a defined sequence. GI / UW can resist multipath delay and can also be used for channel and phase noise estimation, improving system performance. However, GI / UW is affected by partial data leakage, and the equivalent CP is contaminated, degrading system performance in multipath fading environments. Furthermore, the PAPR (Pattern Response Rate) of these two waveforms is the same as that of existing DFT-S-OFDM.

[0219] However, using E-DFT-s-OFDM waveforms for communication offers the following advantages: E-DFT-s-OFDM waveforms insert header and tail sequences on each symbol and add FDSS processing in the frequency domain. The inserted header and tail sequences can resist multipath delay differences, and the sequences are flexibly copied from the reference signal symbols, with variable lengths that do not affect the symbol duration. FDSS effectively suppresses interference from the data portion to the tail sequence while reducing PAPR.

[0220] The traditional DFT-s-OFDM differs from the E-DFT-s-OFDM of this disclosure in the following ways:

[0221] In a traditional DFT-S-OFDM waveform, a slot comprises 14 OFDM symbols, each with a CP (Concurrent Carrier Component). The duration of each OFDM symbol includes the useful symbol duration and the CP duration (the useful symbol duration refers to the duration of the time-domain data after the Inverse Discrete Fourier Transform (IDFT), which is equal to the reciprocal of the subcarrier spacing (SCS)). At the receiver, the signal to be demodulated is the output of the useful symbol DFT, and the CP is discarded. The CP does not adjust with changes in multipath delay; for a given SCS, if the CP duration changes, the duration of each OFDM symbol will also change.

[0222] In an E-DFT-S-OFDM waveform, a slot comprises 15 OFDM symbols. The duration of each symbol is the IDFT data, equal to the reciprocal of the SCS. The 15 OFDM symbols include one reference signal symbol and 14 data symbols. Each data symbol includes a header sequence, a tail sequence, and the data itself. The tail sequence is identical across all symbols within a time slot and can be considered the equivalent CP of the next symbol. The header sequence is also identical across all symbols within a time slot. Oversampling reduces interference from data to the tail sequence, ensuring that the tail sequences of adjacent symbols are identical.

[0223] In E-DFT-S-OFDM waveforms, the header and tail sequences serve as reference signals used for time-frequency synchronization, channel estimation, and phase noise estimation. These sequences can be copied from the header and tail of the reference signal symbols, respectively, making their configuration more convenient and flexible. The tail sequence length is variable, adaptable to changes in multipath delay, further improving spectral efficiency. For example, the tail sequence can be shortened when multipath delay is small, allowing the data portion to be longer.

[0224] Currently, 5G NR supports flexible SCS parameters, ranging from 15kHz to 240kHz. As the carrier frequency increases, the SCS will also increase.

[0225] In this embodiment, the implementation method of the E-DFT-S-OFDM transmitter is as follows: (1) The transmitter generates encoded and modulated data; (2) Header and tail sequences are inserted; (3) DFT is performed to obtain discrete frequency domain data; (4) Subcarrier mapping is performed after adding FDSS processing and zeros are padded; (6) Finally, IDFT is performed to generate oversampled time domain information and then transmitted via RF.

[0226] In this embodiment, the transmission differences between the E-DFT-S-OFDM waveform and the traditional DFT-S-OFDM waveform are as follows:

[0227] 1) Different OFDM symbols include inserted head and tail sequences;

[0228] 2) There is an additional FDSS operation. An exemplary FDSS can use the root raised cosine function to reduce PAPR and suppress energy leakage of data to the tail sequence.

[0229] 3) No need to add CP.

[0230] In this embodiment, the implementation method of the E-DFT-S-OFDM receiver is as follows: (1) At the receiver, the received data is transferred to the frequency domain through DFT without removing CP; (2) Subcarrier demapping and FDSS inverse transformation are performed; (3) IDFT operation is performed to obtain the data; (4) Phase noise compensation is performed through the header and tail sequences; (5) Finally, the header and tail sequences are removed, demodulated, and the original data is recovered.

[0231] In this embodiment, the reception differences between E-DFT-S-OFDM waveforms and traditional DFT-S-OFDM waveforms are as follows:

[0232] 1) No CP removal operation is required;

[0233] 2) Additional FDSS inverse transform is required;

[0234] 3) Phase noise compensation is performed using the head and tail sequences;

[0235] 4) Remove the head and tail sequences before demodulation.

[0236] In this embodiment, by employing E-DFT-S-OFDM waveforms for communication, not only can the differences in multipath delay be resisted, but the header and tail sequences can also be flexibly copied from the reference signal symbols with variable lengths, without affecting the symbol duration. FDSS can effectively suppress interference of the data portion on the tail sequence and reduce PAPR, thereby solving the problem of poor traditional waveform performance in uplink and downlink channels in related technologies and achieving the effect of improving spectral efficiency.

[0237] In some embodiments, the head sequence and tail sequence of the E-DFT-S-OFDM waveform are derived from or copied from a reference signal. Figure 10 is a schematic diagram of the head sequence and tail sequence of a second waveform in an embodiment of the present disclosure. As shown in Figure 10, the head sequence (such as S1) in the second waveform (E-DFT-S-OFDM waveform) may be derived from the head of the reference signal, and the tail sequence (such as S2) in the E-DFT-S-OFDM waveform may be derived from the tail of the reference signal.

[0238] In some embodiments, the specific configuration of the E-DFT-s-OFDM waveform may be related to the environment and channel conditions of the UE / TRP; that is, different transmission scenarios may correspond to different waveform configurations. In modern wireless communication systems, the quality and efficiency of signal transmission are affected by a variety of factors, the most critical of which is the delay spread phenomenon under multipath propagation conditions. Multipath propagation causes signals to experience different delays before reaching the receiver, resulting in time-domain dispersion at the receiver. This not only increases the risk of inter-symbol interference (ISI) but may also introduce inter-carrier interference (ICI), severely impacting the overall system performance. If fixed-length header and tail sequences are used, the system cannot respond promptly to environmental changes, potentially leading to a significant decrease in signal quality and transmission efficiency.

[0239] To address the aforementioned issues, the length of the header and / or tail sequence is determined based on environmental awareness information. This allows the base station / core network / UE to report / configure environmental information or measurements of other signals. For example, the sequence length can be increased to enhance robustness when high latency spread is detected, while appropriately shortening the sequence length in a LOS environment to improve spectral efficiency. This method meticulously considers the characteristics of multipath propagation in different scenarios, ensuring optimal header / tail sequence configuration in every case. Unnecessary overhead is reduced while maintaining signal integrity, thereby improving the overall UE experience.

[0240] Base stations can determine sequence configurations through various methods, such as environmental feature extraction: extracting key environmental features by analyzing the multipath component distribution and power spectral density map in the CSI report; decision model construction: using machine learning techniques to train a decision model that can accurately predict the optimal sequence length; and real-time adjustment mechanism: embedding the above model into the base station controller and setting a periodic update mechanism to reflect the latest environmental changes.

[0241] In this embodiment, when configuring the E-DFT-S-OFDM waveform, at least one of the following parameters can be configured: head sequence length, tail sequence length, and a combination of the head sequence length and tail sequence length.

[0242] In this embodiment, when configuring the E-DFT-S-OFDM waveform, the reference signal can also be configured, including at least one of the following parameters: the sequence number of the reference signal, the sequence length of the reference signal, the initialization sequence type, the initialization sequence length, etc.

[0243] In some embodiments, the waveform configurations described above, such as the head / tail sequence length configuration, are determined based on the CSI report / environment / perception status reported by the UE. The environment / perception status can be obtained by the base station sensing the environment and acquiring the multipath delay of the environment. Specifically, it is related to at least one of the following: delay spread, sensing the environment, LOS / NLOS indication, etc.

[0244] In an exemplary embodiment, if it is a sensing / localization reference signal, the length of the head and / or tail sequence can be configured in the following way:

[0245] 1) TRP suggests sending configuration recommendations and some environmental information to SF / LMF, which then configures the UE:

[0246] a) Configuration recommendations may include suggested lengths for the head and / or tail sequences;

[0247] b) Environmental information may include latency spread, perceived environment, LOS / NLOS indication, etc.;

[0248] c) The configuration provided by SF / LMF to the UE can be transparently transmitted to the UE by TRP;

[0249] 2) The SF / LMF sends configuration suggestions / some environmental information to the TRP, which then configures the UE.

[0250] a) Configuration recommendations may include suggested lengths for the head and / or tail sequences;

[0251] b) Environmental information may include latency spread, perceived environment, LOS / NLOS indication, etc.;

[0252] 3) The SF / LMF sends configuration suggestions / some environmental information to the UE; the length is determined by the UE.

[0253] a) Configuration recommendations may include suggested lengths for the head and / or tail sequences;

[0254] b) Environmental information may include latency spread, perceived environment, LOS / NLOS indication, etc.

[0255] Through the above embodiments, the UE can communicate with the base station using E-DFT-S-OFDM waveforms. The waveform configuration is very flexible and can be configured in conjunction with environmental perception information, making it more adaptable to environmental changes. Different network elements can negotiate with each other on perception information and waveform configuration information to meet the capabilities or needs of different devices, thereby improving the overall communication performance of the system.

[0256] In another exemplary embodiment of this disclosure, the user equipment and the first network element communicate using an FDSS-based waveform. Since the E-DFT-S-OFDM waveform described above also uses FDSS modulation, the FDSS-based waveform can also be an E-DFT-S-OFDM waveform. However, this disclosure is not limited to this. FDSS can also be added to other waveforms, such as the conventional DFT-S-OFDM waveform.

[0257] In some embodiments, using FDSS in uplink DFT-s-OFDM waveform processing can reduce the PAPR of the uplink signal. The basic idea is to perform designed spectrum shaping in the frequency domain data after the DFT and before the IFFT of the DFT-s-OFDM waveform. The parameters of FDSS can be represented by a set of time-delay discrete data. Currently, uplink waveform processing methods are divided into non-transparent and transparent methods.

[0258] In the non-transparent mode, the transmitter uses FDSS modulation technology, and the receiver needs to know the transmitter's FDSS modulation parameters during demodulation. The transmitting end process includes: after modulation, the transmitted data undergoes DFT to transform from the time domain to the frequency domain; FDSS is performed in the frequency domain; then IFFT is performed to transform it back from the frequency domain to the time domain; finally, CP is added before transmission. The receiving end process includes: after removing CP, the receiver performs FFT to transform from the time domain to the frequency domain; then IFDSS is performed in the frequency domain; finally, equalization and IDFT are performed; and finally, the original data is recovered after demodulation.

[0259] In the transparent mode, the reference signal also needs to undergo FDSS processing. At the receiver, IFDSS can be combined with the response coefficients of the wireless channel for frequency domain equalization. A set of discrete time-delay data in FDSS processing can be represented as:

[0260] a n D-2n-1 +…+a1D -1 +a0+b1D 1 +…+b n D 2n+1 ;

[0261] Among them, the parameter that needs to be determined is a. n ,…,a1,a0,b1,…,b n .

[0262] In FDS, several key parameters affect system performance, including but not limited to:

[0263] Link budget: determines the effective communication range and signal strength requirements between the base station and the UE.

[0264] Transmit Power Control (TPC) threshold: used to balance the uplink and downlink quality between the base station and the UE to prevent self-interference.

[0265] Adaptive Modulation and Coding (AMC) mode selection: dynamically adjusts the balance between data rate and bit error rate based on the current channel conditions.

[0266] Interference coordination mechanism activation conditions: Define when and how to implement interference management strategies to mitigate self-interference effects.

[0267] Multiple Access Technology Selection: Balancing system capacity and complexity, a choice is made between solutions such as OFDMA and SCMA. For FDSS, the base station and UE can exchange relevant FDSS parameters, which can be recommended / configured by LMF / SF / CN based on perception-related conditions. Specifically, the data collection and preprocessing stage may include the following steps: Environmental Awareness and Channel Measurement: The base station and UE periodically monitor the environment, collecting data on key indicators such as multipath delay spread, LOS / NLOS ratio, signal-to-noise ratio (SNR), and reciprocity deviation. Historical Record Analysis: Analyzing best practice patterns in specific scenarios by combining past operation logs.

[0268] In this embodiment of the disclosure, the waveform configuration parameters based on the FDSS waveform may include the following parameters: the number of modulation parameters, the values ​​of the modulation parameters, the index of the modulation parameters, and 1 bit indicating whether and / or the modulation type is supported.

[0269] In this embodiment, the number and / or values ​​of the modulation parameters can be determined based on the CSI report / environment / awareness information reported by the UE, thereby improving the adaptability of the waveform in different communication environments and enhancing communication performance. The environmental awareness information includes at least one of the following: delay spread, perceived environment, LOS / NLOS indication, etc.

[0270] Furthermore, the waveform configuration parameters related to FDSS mentioned above can also be implemented by combining the various waveform configuration parameters of the E-DFT-S-OFDM waveform in the previous embodiments.

[0271] In one exemplary embodiment, the number of modulation parameters and / or the values ​​of the modulation parameters can be configured in the following ways:

[0272] 1) TRP suggests sending configuration recommendations / some environmental information to SF / LMF, which then configures the UE;

[0273] 2) The SF / LMF sends configuration suggestions / some environmental information to the TRP, which then configures the UE.

[0274] 3) SF / LMF sends configuration suggestions / some environmental information to the UE, the length of which is determined by the UE.

[0275] In an exemplary embodiment, the UE may report its FDSS recommendation / capability information to the base station or network: 1 bit indicates whether there is a corresponding processing capability or whether it is recommended to use this waveform, the number of supported / recommended parameters, the index of supported / recommended parameters, and / or the supported modulation type.

[0276] Through the above embodiments, the UE can communicate with the base station using FDSS-based waveforms. The waveform configuration is highly flexible and can be combined with environmental awareness information for better adaptation to changing environments. Different network elements can negotiate with each other regarding awareness and waveform configuration information to meet the capabilities or needs of different devices, thereby improving the overall communication performance of the system. By applying the above interactive parameter configuration scheme, FDSS can achieve more flexible, intelligent, and efficient bidirectional communication services. It not only enhances the overall adaptability and robustness of the network but also lays a solid theoretical and technical foundation for the ultra-dense networking modes of the future 5G and even 6G era.
