[0106] Figure 1 is a schematic diagram of the architecture of a communication system provided according to an embodiment of the present disclosure. As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102.

[0107] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0111] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0112] In some embodiments, the communication system 100 described above may be a 4G communication system, a 5G communication system, or a 6G communication system. It should be noted that the communication system 100 may also be other communication systems, and this disclosure does not specifically limit them.

[0113] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0114] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or some of the main components in the communication system 100, but are not limited thereto. The main components shown in FIG1 are illustrative. The communication system 100 may include all or some of the main components in FIG1, or may include other main components other than those in FIG1. ​​The number and form of each main component are arbitrary.

[0115] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0116] To improve uplink (UL) coverage and throughput, 3GPP researched and standardized SBFD in the duplex enhancement projects of Rel-18 (release 18) and Rel-19 (release 19). Specifically, a carrier component (CC) divides a downlink (DL) symbol or a flexible symbol (or F symbol) into multiple subbands (SBs) within the frequency domain. These SBs can include one UL subband and at least one (e.g., one or two DL subbands). A base station can transmit DL signals in the DL subband and simultaneously receive UL signals in the UL subband. In this case, when a symbol simultaneously contains both a DL subband and a UL subband in the frequency domain, that symbol can be called an SBFD symbol. Similarly, when at least one SBFD symbol exists among the multiple symbols contained in a timeslot, that timeslot can be called an SBFD timeslot.

[0117] Figure 2 is a schematic diagram of an SBFD time slot provided according to an embodiment of the present disclosure. As shown in Figure 2, in time slots #0, #1, #2, #3, and #4, time slot #0 is a DL time slot, time slots #1 to #3 are SBFD time slots, and time slot #4 is a UL time slot. Time slot #0 may contain 14 DL symbols. Each time slot from #1 to #3 may contain 14 SBFD symbols. Time slot #4 may contain 14 UL symbols.

[0118] In some embodiments, a guard band (GB) may exist between the UL subband and the DL subband. The guard band can be used to isolate the UL subband and the DL subband in the frequency domain, thereby reducing interference between the DL signals in the DL subband and the UL signals in the UL subband.

[0119] For base stations using SBFD technology, the simultaneous presence of uplink and downlink services may cause downlink transmission from one base station to interfere with uplink reception from another base station.

[0120] Figure 3 is a schematic diagram of an uplink muting scenario provided according to an embodiment of this disclosure. As shown in Figure 3, gNB1 performs downlink transmission on the downlink subband of time slot #1, and gNB2 performs uplink reception on the uplink subband of time slot #1. Due to signal leakage, the downlink signal transmitted by gNB1 may cause cross-link interference to the uplink signal received by gNB2. To measure this cross-link interference, gNB2 can perform cross-link interference measurement on the uplink subband of time slot #1. However, if the UE sends a measurement signal to gNB2 on the measurement resources of gNB2 at this time, then the signal measured by gNB2 will be the superposition of the interference signal and the measurement signal sent by the UE. This will affect the accuracy of cross-link interference measurement. Therefore, in the Rel-19 standardization, some resources in the PUSCH transmitted by the UE will be muted, that is, no uplink signal will be transmitted on these resources, thereby ensuring that the cross-link interference measured by gNB2 on the muted resources is clean. The UE's silent pattern is the comb-2 pattern, meaning that uplink data is rate-matched on either odd or even subcarriers, and no data is transmitted. When the UE transmits PUSCH using a DFT-S-OFDM waveform, an additional conversion precoding step is added compared to the CP-OFDM waveform.

[0121] Figure 4 is a partial flowchart illustrating the PUSCH processing of a DFT-S-OFDM waveform according to an embodiment of this disclosure. As shown in Figure 4, the processing flow of the PUSCH using a DFT-S-OFDM waveform on the terminal side includes: scrambling, modulation, layer mapping, transform precoding, precoding, mapping to virtual resource blocks, and mapping to physical resource blocks.

[0122] In some embodiments, the specific implementation of the conversion precoding may differ depending on whether PT-RS is used or not.

[0123] In some embodiments, without using PT-RS, for a single layer λ=0 complex value symbol block It should be classified as In each set, each set corresponds to an OFDM symbol, and yes The length of each set is an integer multiple of the total length. This is the input data for the DFT. Subsequently, each set is fed into an input of length [length missing]. The DFT. The output of the DFT is the output of the transformation pre-encoder. In some embodiments, The number of frequency domain subcarriers corresponding to one OFDM symbol in the PUSCH resource allocation.

[0124] In some embodiments, when using PT-RS, complex number symbol blocks It should be divided into sets, each set corresponding to one OFDM symbol, and wherein set l contains Each symbol is mapped to a complex numerical symbol corresponding to OFDM symbol l. Above, among which, If a set does not contain PT-RS, then the set contains All data points come from the input of the transformation pre-encoded dataset. At this point, ε l The value equals 0. If a set contains PT-RS, then the value in that set is 0. The data consists of the input from the transformation precoded data and the inserted PT-RS. At this point, ε l It equals 1. Subsequently, each set is fed into a stream of length 1. The DFT is then used as the output of the transformation precoder.

[0125] In some implementation sets, the uplink silence pattern may occupy one or more OFDM symbols in the time domain. For example, the silence pattern may occupy one or two OFDM symbols in the time domain. In some embodiments, the uplink silence pattern may be comb-shaped in the frequency domain. For example, the uplink silence pattern may be comb-2 in the frequency domain. If valid, the uplink silence pattern will cover all frequency domain configuration resources of the PUSCH.

[0126] Figure 5 is a schematic diagram of the PUSCH and silent resources in a virtual resource block provided according to an embodiment of this disclosure. As shown in Figure 5, a PUSCH occupies 6 OFDM symbols in the time domain, for example, from symbol #3 to symbol #8, and occupies 2 physical resource blocks (PRBs) in the frequency domain. Meanwhile, the silent pattern configured for the UE PUSCH is indicated by the shaded area and is located on symbols #3 and #6. The comb offset of the silent pattern is 0, meaning it is located on even-numbered carriers of all PRBs in the frequency domain of this PUSCH. Therefore, the silent resource elements (REs) of this PUSCH are shown in the figure. PUSCH data cannot be mapped on these REs.

[0127] Therefore, how to implement the conversion precoding of PUSCH in the presence of silent resources is a technical problem that urgently needs to be solved.

[0128] Figure 6 is an interactive schematic diagram of the communication method provided according to an embodiment of the present disclosure. The communication method involved in this embodiment can be applied to a communication system 100. As shown in Figure 6, the communication method of this embodiment includes steps S601 to S604.

[0129] In step S601, network device 102 sends configuration information to terminal 101.

[0130] In some embodiments, network device 102 may send configuration information. In some embodiments, the configuration information may be sent by network device 102, but is not limited to this, and may also be sent by other entities.

[0131] In some embodiments, terminal 101 may receive configuration information. In some embodiments, the configuration information may be received by terminal 101, but is not limited thereto, and may also be received by other entities.

[0132] In some embodiments, the configuration information may be used to indicate the configuration of the first resource. In some embodiments, the configuration information may be used by terminal 101 to determine the configuration of the first resource.

[0133] In some embodiments, the first resource may be an uplink silent resource. In some embodiments, configuration information may be used to indicate the silent resource when sending a PUSCH.

[0134] In some embodiments, the first resource may be distributed in a comb-like pattern in the frequency domain. In some embodiments, the first resource may include a plurality of first subcarriers distributed in a comb-like pattern in the frequency domain. In some embodiments, the first resource may be distributed in a comb-2 manner in the frequency domain. This means that any two adjacent first subcarriers among the plurality of first carriers may be spaced apart by a second subcarrier.

[0135] In some embodiments, PUSCH may not be sent on the first resource. In some embodiments, the first resource may be a resource in a virtual resource block that is not used for sending. Therefore, the first resource may be referred to as a mutating resource.

[0136] In some embodiments, the configuration information may indicate at least one of the following: time-domain location, or comb offset in the frequency domain.

[0137] In some embodiments, the time-domain location can be the time-domain symbol where the first resource is located. In one example, the first resource can be located in one OFDM symbol. For example, the first resource can be located at OFDM symbol #3. In one example, the first resource can be located in two OFDM symbols. For example, the first resource can be located at OFDM symbols #3 and #5. It is understood that the first resource can also be located in more OFDM symbols in the time domain, and this disclosure does not specifically limit this.

[0138] In some embodiments, a comb offset can be used to determine the starting position of a first resource in the frequency domain. In one example, the configuration information may include a field indicating the comb offset. In this field, a first value may indicate a comb offset of 0, and a second value may indicate a comb offset of 1. It is understood that the first resource is distributed in a comb-2 manner in the frequency domain, so the comb offset can range from {0,1}. In one example, a comb offset of 0 indicates that the first resource is located on an even-numbered carrier. A comb offset of 1 indicates that the first resource is located on an odd-numbered carrier.

[0139] In some embodiments, configuration information may be carried in downlink control information (DCI), radio resource control (RRC) messages, or other messages.

[0140] In some embodiments, the configuration information may not be provided by network device 102. In some embodiments, the configuration information may be agreed upon by a protocol. In some embodiments, the configuration information may be obtained from a higher layer.

[0141] In step S602, terminal 101 processes the data of PUSCH.

[0142] In some embodiments, when configuration information is obtained, terminal 101 can process the data of PUSCH.

[0143] In some embodiments, in order to send the PUSCH to network device 102, terminal 101 may first process the data to be sent via the PUSCH. The processing of the data to be sent via the PUSCH may include: scrambling, modulation, layer mapping, conversion precoding, precoding, virtual resource block mapping, and physical resource block mapping.

[0144] In some embodiments, the data to be transmitted can be processed by scrambling, modulation and layer mapping to obtain a first symbol block.

[0145] In some embodiments, the first symbol block may be a complex number symbol block. In some embodiments, the first symbol block may include There are 1 first symbols. Each of these first symbols can have a complex value.

[0146] In some embodiments, If the integer is positive, then the first symbol block may include at least one first symbol.

[0147] In some embodiments, step S602 may include: performing a conversion precoding process on the first symbol block according to the configuration of the first resource.

[0148] Figure 7 is a schematic flowchart of a transformation precoding process provided according to an embodiment of the present disclosure. As shown in Figure 7, in some embodiments, the transformation precoding process may include two parts: preprocessing and DFT processing. In some embodiments, the transformation precoding process for a first symbol block may be implemented as follows: preprocessing the first symbol block to obtain at least one symbol set; and performing DFT processing on the at least one symbol set to obtain a second symbol block.

[0149] In some embodiments, each set of symbols may correspond to one OFDM symbol.

[0150] In some embodiments, the transformation precoding process for a symbol set can be implemented in different ways. In some embodiments, the transformation precoding process for a symbol set may include: a first method, a second method, a third method, and a fourth method.

[0151] In some embodiments, the preprocessing performed on the first symbol block may include at least one of the following: first preprocessing, second preprocessing, and third preprocessing.

[0152] First method:

[0153] In some embodiments, in the first approach, PT-RS may not be used. In some embodiments, at least one symbol set may include at least one of the following: a first symbol set and a second symbol set. The OFDM symbol-related time-frequency resource corresponding to a first symbol set may include the first resource. In other words, the first resource may be located within the OFDM symbol-related time-frequency resource corresponding to the first symbol set. The OFDM symbol-related time-frequency resource corresponding to a second symbol set may not include the first resource. For example, at least one symbol set may include a second symbol set, and the number of the second symbol set may be greater than or equal to 1. For example, at least one symbol set may include a first symbol set, and the number of the first symbol set may be greater than or equal to 1. For example, at least one symbol set may include a first symbol set and a second symbol set, and the number of the first symbol set may be greater than or equal to 1, and the number of the second symbol set may be greater than or equal to 1.

[0154] In some embodiments, the first symbol set may include a first number of first symbols in a first symbol block.

[0155] In some embodiments, the second symbol set may include a second number of first symbols from the first symbol block.

[0156] In some embodiments, since the first resources are distributed in a combo-2 manner in the frequency domain, half of the time-frequency resources associated with the OFDM symbols corresponding to the first symbol set can be the first resources. Thus, only half of the time-frequency resources associated with the OFDM symbols corresponding to the first symbol set are used for PUSCH mapping. In this case, the first quantity can be equal to half of the second quantity.

[0157] In some embodiments, the second number may be equal to the number of subcarriers within the scheduling bandwidth of the PUSCH. In one example, the number of first symbols included in the second symbol set may be equal to the number of subcarriers within the scheduling bandwidth of the PUSCH. In one example, the number of first symbols included in the first symbol set may be equal to half the number of subcarriers within the scheduling bandwidth of the PUSCH.

[0158] In some embodiments, the second quantity may be equal to Then the first quantity can be equal to

[0159] In some embodiments, terminal 101 may perform a first preprocessing step to divide the first symbol block into multiple symbol sets. Each symbol set may correspond to one OFDM symbol. When an OFDM symbol does not contain a first resource, the number of first symbols contained in the symbol set corresponding to that OFDM symbol, i.e., the second symbol set, is [number missing]. When an OFDM symbol contains a first resource, the number of first symbols contained in the symbol set corresponding to that OFDM symbol, i.e., the first symbol set, is:

[0160] In some embodiments, the DFT processing performed by terminal 101 on at least one symbol set may include at least one of the following: performing DFT processing on a first symbol set with a sample number equal to a first number; performing DFT processing on a second symbol set with a sample number equal to a second number.

[0161] In some embodiments, terminal 101 may perform DFT processing on each of the at least one set of symbols. In some embodiments, terminal 101 may perform DFT processing on each of the at least one set of symbols sequentially.

[0162] In some embodiments, the DFT processing performed by terminal 101 may be: performing DFT processing on each symbol set sequentially. In one example, the OFDM symbols corresponding to the second symbol set do not contain the first resource, then the size of the DFT processing is... In one example, if the OFDM symbols corresponding to the first symbol set contain the first resource, then the size of the DFT processing is...

[0163] Figure 8A is a schematic diagram of a first example of conversion precoding provided according to an embodiment of the present disclosure. In some embodiments, as shown in Figure 8A, when no PT-RS is used on the PUSCH, the first symbol block is... Here, taking the first symbol block located in the first layer as an example, the superscript of each first symbol in the first symbol block is 0. Terminal 101 performs first preprocessing to divide the first symbol block into multiple symbol sets. Each symbol set corresponds to one OFDM symbol. When the OFDM symbol does not contain a first resource, the number of first symbols contained in the symbol set corresponding to that OFDM symbol is... When an OFDM symbol contains a first resource, the number of first symbols contained in the symbol set corresponding to that OFDM symbol is: The fourth symbol block can be and The DFT is performed sequentially on each symbol set in the fourth symbol block to obtain the output of the transformation precoding, i.e., the second symbol block. When the OFDM symbol corresponding to a symbol set does not contain the first resource, the size of the DFT can be... When a set of symbols corresponds to OFDM symbols that contain the first resource, the size of the DFT can be...

[0164] In some embodiments, as shown in FIG8A, the DFT processing of the first symbol set and the second symbol set can be implemented by different DFT modules. In some embodiments, the DFT processing of the first symbol set and the second symbol set can be implemented by the same DFT module, and this disclosure does not specifically limit this.

[0165] Second method:

[0166] In some embodiments, in the second approach, PT-RS may not be used. In some embodiments, at least one symbol set may include at least one of the following: a first symbol set and a second symbol set. The OFDM symbol-related time-frequency resource corresponding to a first symbol set may include the first resource. In other words, the first resource may be located within the OFDM symbol-related time-frequency resource corresponding to the first symbol set. The OFDM symbol-related time-frequency resource corresponding to a second symbol set may not include the first resource. For example, at least one symbol set may include the first symbol set, and the number of the first symbol set may be greater than or equal to 1. For example, at least one symbol set may include the second symbol set, and the number of the second symbol set may be greater than or equal to 1. For example, at least one symbol set may include both the first and second symbol sets, and the number of the first and second symbol sets may be greater than or equal to 1.

[0167] In some embodiments, the first symbol set may include a first number of first symbols in the first symbol block, and a first number of first additional symbols.

[0168] In some embodiments, the first number of first additional symbols can be obtained by weighting the first number of first symbols using an offset factor. In some embodiments, the first additional symbol corresponding to a first symbol can be obtained by weighting each first symbol in the first number of first symbols using an offset factor. Thus, the first number of first additional symbols corresponding to the first number of first symbols can be obtained.

[0169] It is understandable that if the first quantity is half of the second quantity, then the total number of the first symbol of the first quantity and the first additional symbol of the first quantity equals the second quantity.
