Description

Technical Field

[0001] This invention relates to the field of communications, and more specifically to a signal transmission method, apparatus, communication device, and storage medium. Background Technology

[0002] With the evolution of communication technologies, the standardization process for 6G is gradually approaching. For the deployment frequency bands of 6G networks, the following are typically adopted: Figure 1 The Multi-RAT Spectrum Sharing (MRSS) method, as shown, involves refarming existing Long Term Evolution (LTE) and New Radio (NR) spectrum to enable network devices to provide single-band services for LTE / NR terminals and / or 6G terminals. In other words, by deploying 6G and 5G air interfaces on the same frequency band, network devices can provide services not only to LTE / NR terminals but also to 6G terminals on the same frequency band.

[0003] By adopting the above approach, on the one hand, network operators can update the software without replacing the hardware, which saves deployment costs and greatly improves deployment speed, and enables the early deployment of 6G future industries; on the other hand, LTE and NR spectrum are usually deployed at lower frequencies, and deploying 6G networks at these frequencies can improve the overall coverage performance of the network while reducing the cost of deploying sites.

[0004] However, correspondingly, both LTE and NR systems have some normally active signals, such as Cell-Specific Reference Signal (CRS), Synchronization Signal / PBCH Block (SSB), System Information Block 1 (SIB1), and Physical Random Access Channel (PRACH). When refarming existing LTE and NR spectrum, 6G transmission signals will have time-frequency resource overlap with the normally active signals of LTE and NR systems, leading to resource collisions and affecting spectrum sharing. Therefore, how to ensure the coexistence of 6G air interface with LTE and NR during transmission / scheduling is an urgent problem to be solved. Summary of the Invention

[0056] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0057] The technical solutions of this invention can be applied to various communication systems, such as GSM (Global System for Mobile communication), LTE, or 5G systems. Optionally, a 5G system or 5G network can also be referred to as an NR system or NR network.

[0058] For example, the communication system used in this embodiment of the invention may include network devices and terminal devices (also referred to as terminals, communication terminals, etc.); the network device may be a device that communicates with the terminal device. The network device can provide communication coverage within a certain area and can communicate with terminals located within that area. Optionally, the network device may be a base station in various communication systems, such as an evolved Node B (eNB) in an LTE system, or a gNB in ​​a 5G or NR system.

[0059] It should be understood that devices with communication functions in the network / system of this application embodiment can be referred to as communication devices. Communication devices may include network devices and terminals with communication functions. Network devices and terminal devices can be the specific devices described above, which will not be repeated here. Communication devices may also include other devices in the communication system, such as network controllers, mobility management entities, and other network entities. This embodiment of the present invention does not limit these.

[0060] It should be understood that the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0061] The terms “first,” “second,” etc., used in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0062] Before providing a detailed description of the signal transmission method according to the embodiments of the present invention, a brief description of the related technologies will be given first.

[0063] In some scenarios, NR networks refarm already deployed LTE spectrum, meaning that both NR and LTE networks operate on the same frequency band. In this mode, there is a time-frequency resource overlap between the NR system's signals and the LTE system's normally open signals. To address this issue, Dynamic Spectrum Sharing (DSS) is introduced in NR systems to mitigate the impact of resource collisions caused by normally open signals. Specifically, the following normally open signals in LTE need to be considered for avoidance:

[0064] 1) CRS: This is one of the most commonly used normally open signals in LTE. This reference signal is transmitted in each downlink time slot. Typically, CRS is transmitted over four OFDM symbols in one LTE time slot. Figure 2 This is a schematic diagram of the CRS transmission time slots; as shown. Figure 2 As shown, CRS is transmitted on symbols 1, 5, 8, and 12 of the time slot.

[0065] 2) Multimedia Broadcast Single Frequency Network (MBSFN) subframe: This is a data transmission format introduced in LTE for multicast services. Figure 3This is a schematic diagram of the transmission format based on MBSFN subframes; for example... Figure 3 As shown, in this format, each MBSFN subframe includes 14 Orthogonal Frequency Division Multiplexing (OFDM) symbols. The first two OFDM symbols in each subframe are used to transmit the CRS and the Physical Downlink Control Channel (PDCCH).

[0066] To address the two normally open signals mentioned above, the DSS mechanism introduced in the NR system incorporates a design to avoid various signals in the NR, specifically including the following signals:

[0067] 1) For SSB signals, the DSS mechanism has been designed as follows for both non-MBSFN and MBSFN scenarios:

[0068] Figure 4 This is a schematic diagram of SSB transmission patterns in non-MBSFN scenarios; for example... Figure 4 As shown, for non-MBSFN scenarios, NR designed the SSB transmission pattern Case B. Under the transmission pattern of 30kHz SSBs (SSB#0, SSB#1, SSB#2 and SSB#3) carried on the Physical Downlink Shared Channel (PDSCH) with a subcarrier spacing of 15 kHz, SSB#0 can avoid the pattern transmission of LTE CRS.

[0069] Figure 5 This is a schematic diagram of the SSB transmission pattern in an MBSFN scenario; for example... Figure 5 As shown, for the MBSFN scenario, NR designed SSB transmission patterns Case A / B / C. Under multiple transmission patterns carrying 30kHz SSBs (SSB#0, SSB#1, SSB#2, SSB#3) on a PDSCH with a subcarrier spacing of 15kHz, the SSBs can completely or partially avoid the transmission of LTE CRS.

[0070] 2) For PDSCH transmission, the DSS mechanism has made the following designs for both the demodulation reference signal (DM-RS) and data transmission:

[0071] For DM-RS, Figure 6 This is a schematic diagram of the transmission pattern of DM-RS in the PDSCH under the existing NR system; for example... Figure 6As shown, on an NR PDSCH with a subcarrier spacing of 15 kHz and a start and length indication value of 40 (i.e., 13 symbols), it can be seen from the symbol index of NR and the symbol index of LTE that NR DM-RS can completely avoid the transmission of LTE CRS.

[0072] For data transmission, the DSS mechanism employs RE-level and RB-level puncturing mechanisms. Specifically, network devices can configure RE-level (e.g., LTE CRS transmission patterns) or RB-level (e.g., frequency and time domain resources requiring puncturing) patterns to terminal devices, so that when receiving data, the terminal device will not transmit the resources at the puncturing locations by default. In other words, puncturing is performed on the configured resources when receiving data.

[0073] As an example, existing technology designs a pattern for configuring rate matching around LTE CRS, called RateMatchPatternLTE-CRS. Specifically, the resource configuration process for RateMatchPatternLTE-CRS may include the following fields:

[0074]

[0075] As another example, existing technology also designs a rate matching pattern for configuring PDSCH, called RateMatchPattern. Specifically, the resource configuration process for RateMatchPattern may include the following fields:

[0076]

[0077] Secondly, a brief explanation of normally open signals in existing NR / LTE systems will be given.

[0078] In NR / LTE systems, normally open signals refer to signals that network devices need to periodically send or receive in current 5G, 4G, and other networks. These typically include the following types of signals:

[0079] 1) SSB: Terminal devices can perform time-domain / frequency-domain / spatial-domain synchronization, automatic gain control (AGC) calibration (usually requiring the reception of 2-3 SSBs) and receive system information (such as SIB1) based on SSB.

[0080] Specifically, after powering on, the terminal device first scans the possible frequency points of the SSB (i.e., the frequency domain position of the synchronization signal block) based on the synchronization grid to obtain the SSB beam transmitted by the base station through blind detection. For example, the definitions of the synchronization grid and the frequency domain position of the synchronization signal block can be shown in Table 1.

[0081] Table 1

[0082]

[0083] The SSB includes the Primary Synchronization Signal (PSS), the Secondary Synchronization Signal (SSS), and the PBCH block. The PSS / SSS carries the cell's physical identifier and can be used for time-domain, frequency-domain, and spatial-domain synchronization. The PBCH carries the MIB (also known as the minimum system information (MSI)), which indicates the time-domain resource locations of spatial information, timing information, some basic cell information, and control information for scheduling SIB1 (such as the PDCCH).

[0084] Based on the preset transmission pattern for the given frequency and the half-frame bits indicated in the MIB, the terminal device can complete timing synchronization. The preset transmission pattern indicates which OFDM symbols the SSB will transmit on within a half-frame. The correspondence between the preset transmission patterns for different frequencies and their operating band, subcarrier spacing (SCS), and GSCN range is shown in Table 2.

[0085] Table 2

[0086]

[0087] As shown in Table 2, each case represents a predefined transmission pattern within a half-frame length. For example, the transmission pattern for Case A corresponding to the 15kHz SCS can be defined as follows: the index of the first symbol of the candidate SS / PBCH block is {2,8}+14·n.

[0088] For operations without shared spectrum channel access, when the carrier frequency is less than or equal to 3 GHz, n = 0, 1. That is, for frequencies less than 3 GHz, there are a maximum of 4 SSB indices within one SSB burst, which are transmitted starting with the 2nd, 8th, 16th, and 22nd OFDM symbols in the half-frame, respectively. When the carrier frequency is greater than 3 GHz and within the frequency range (FR) 1 (i.e., greater than 3 GHz and less than 6 GHz), n = 0, 1, 2, 3. That is, for frequencies greater than 3 GHz and less than 6 GHz, there are a maximum of 8 SSB indices within one SSB burst, which are transmitted starting with the 2nd, 8th, 16th, 22nd, 30th, 36th, 44th, and 50th OFDM symbols in the half-frame, respectively. For operations with shared spectrum channel access, n = 0, 1, 2, 3, 4.

[0089] Furthermore, during initial access, the terminal device can default to a SSB transmission period of 20ms. Since SSB is typically used for basic synchronization and AGC / RRM functions, it does not have the concept of a port, meaning that the terminal device can only measure the channel of a single transmitter antenna based on the SSB.

[0090] 2) SIB1: Also known as Remaining Minimum System Information (RMSI), it carries the main configuration information of the cell. In the prior art, SIB1 is usually broadcast periodically.

[0091] SIB1 can be scheduled using a PDCCH scrambled with a System Information Radio Network Temporary Identifier (SI-RNTI). The time and frequency domain locations of the Control Resource Set (CORESET) and Common Search Space (CSS) set corresponding to this PDCCH are indicated by the MIB. The SSB's MIB includes a PDCCH-ConfigSIB1 field, the high 4 bits of which indicate the time and frequency resources of the CORESET corresponding to the Type0-PDCCH CSS set.

[0092] Specifically, the high 4 bits can indicate 16 possible values. These values ​​determine parameters such as the multiplexing mode of CORESET0 and SSB, the number of RBs occupied by CORESET0 in the frequency domain, and the number of OFDM symbols occupied by CORESET in the time domain, thus determining the time-frequency position of CORESET0. Correspondingly, the last 4 bits of PDCCH-configSIB1 indicate the time-domain detection timing corresponding to Type0-PDCCH CSSset (CSS0). Specifically, the low 4 bits can indicate 16 possible values, and these values ​​determine the corresponding time-domain detection timing.

[0093] In addition, the default transmission period for SIB1 and its scheduling PDCCH can be set to 20ms.

[0094] 3) PRACH: This is the uplink common signal, primarily used for initiating random access and completing uplink timing synchronization between different terminal devices. PRACH can be configured based on SIB1 instructions. Specifically, the resource configuration of PRACH can include the following fields:

[0095] RACH-ConfigGeneric::=SEQUENCE{

[0096] prach-ConfigurationIndex INTEGER(0..255),

[0097] msg1-FDM ENUMERATED{one,two,four,eight},

[0098] msg1-FrequencyStart INTEGER(0..maxNrofPhysicalResourceBlocks-1), ......

[0100] Among them, prach-ConfigurationIndex indicates the time-domain resource configuration of PRACH; msg1-FrequencyStart and msg1-FDM indicate the frequency-domain starting position of PRACH resources and the number of frequency-domain resources occupied, respectively.

[0101] 4) Paging: This is a paging message primarily used to indicate to the terminal device that a data transmission service has arrived, thereby prompting the terminal device to enter a connected state. Paging can also be used to notify of changes to system information (such as SIB1). Paging can also be configured based on SIB1 indications. Specifically, the resource configuration for paging can include the following fields:

[0102]

[0103] Here, `defaultPagingCycle` indicates the paging cycle, and `nAndPagingFrameOffset` indicates the density and corresponding offset of radio frames containing the paging opportunity throughout the paging cycle. For example, when the paging cycle is 128 RFs, the configuration value of `nAndPagingFrameOffset` is halfT and 1, and the RFs containing the paging opportunity are in the 1st, 3rd, 5th, ..., 125th, 127th radio frames of each paging cycle.

[0104] Furthermore, the paging cycle is defined with the System Frame Number (SFN) = 0 as the starting point; the frequency domain position of the paging cycle is related to its associated search space and CORESET.

[0105] Next, after introducing the normally open signals in the existing NR / LTE system, a brief explanation of the reference signals in the existing NR / LTE system will be given.

[0106] 1) DM-RS: Usually sent along with PDCCH and PDSCH / PUSCH, its main functions are channel estimation and auxiliary data demodulation. The current DM-RS pattern is configured by the network to the terminal device. Specifically, the protocol configures the PDSCH mapping type, single-symbol / double-symbol mode, DM-RS configuration type, and the port resources used by the terminal device for DM-RS.

[0107] As an example, the parameters for one configuration type of DM-RS can be shown in Table 3.

[0108] Table 3

[0109]

[0110] As another example, the PDSCH DM-RS position of a single-symbol DM-RS The configuration parameters are shown in Table 4.

[0111] Table 4

[0112]

[0113] 2) CSI-RS: Channel State Information Reference Signal, mainly divided into three types: periodic transmission, semi-static transmission, and aperiodic transmission. The main functions of CSI-RS are channel measurement, interference measurement, and beam management. Specifically, network devices configure the transmission period and offset, frequency domain type, and time domain transmission pattern of CSI-RS. For example, the resource configuration process for CSI-RS may include the following fields:

[0114]

[0115] NZP-CSI-RS-RESOURCE refers to the NZP CSI RS resources used to configure non-zero power (NZP) CSI-RS transmission in cells containing IEs, on which terminal devices can be configured to perform measurements. Furthermore, configuration changes to NZP CSI RS resources between periodic, semi-persistent, and aperiodic modes are not supported unless they are released and added.

[0116] 3) SRS: This stands for Channel Sounding Reference Signal, and it is mainly divided into three types: periodic transmission, semi-static transmission, and aperiodic transmission. Its main functions are channel measurement and beam management. Specifically, network devices configure the SRS with CSI-RS transmission period and offset, frequency domain type configuration, and time domain transmission pattern configuration. For example, the SRS resource configuration process may include the following fields:

[0117]

[0118]

[0119] Currently, for 6G network frequency band deployment, existing LTE and NR spectrum is refarmed, allowing network equipment to provide services not only to LTE / NR terminals but also to 6G terminals within the same frequency band. However, based on the normally open signals and reference signals in the existing NR / LTE systems, and the resource mapping method used when refarming the deployed LTE spectrum in the NR network, there is a time-frequency resource overlap between 6G transmission signals and the normally open signals of the LTE and NR systems during spectrum refarming. This leads to resource collisions and affects spectrum sharing. Therefore, how to ensure coexistence between the 6G air interface and LTE and NR during transmission / scheduling is a problem that urgently needs to be solved.

[0120] Based on this, an embodiment of the present invention proposes a signal transmission method, which is applied to a terminal device. Figure 7 This is a flowchart illustrating the signal transmission method according to an embodiment of the present invention. Figure 1 ;like Figure 7 As shown, the method includes:

[0121] Step 101: Receive or send a first signal, the first signal indicating that a first RAT is enabled, and / or, the first signal is associated with the first RAT; wherein, the first RAT is a 6G network RAT, or, the first RAT is different from a second RAT; the second RAT is a RAT of any of the following networks: 5G network, 4G network, 3G network, 2G network.

[0122] Here, the terminal device in this embodiment of the invention can also be referred to as a terminal, which is a device with wireless transceiver capabilities and supports 6G networks as well as RATs different from 6G networks (e.g., 5G, 4G, 3G, 2G networks). The terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it can also be deployed on water (e.g., ships and other water transport); and it can also be deployed in the air (e.g., airplanes, drones, and satellites). The terminal device can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality terminal device, augmented reality terminal device, wireless terminal device in industrial control, wireless terminal device in autonomous driving, wireless terminal device in telemedicine, wireless terminal device in smart grids, wireless terminal device in transportation safety, wireless terminal device in smart cities, or wireless terminal device in smart homes. The terminal device can also be fixed or mobile. This application embodiment does not limit this.

[0123] In this embodiment, the terminal device indicates that the first RAT is enabled or indicates that the first signal is associated with the first RAT by receiving or sending a first signal. The first RAT can be a different RAT from NR and LTE (i.e., 5G, 4G, 3G, and 2G networks), such as the RAT for 6G networks, or a RAT corresponding to other new architectures. That is, the terminal device and the network device use the first signal to indicate that both support 6G networks.

[0124] Specifically, when the terminal device receives the first signal, the network device instructs the first RAT to be enabled via the first signal, and / or the first signal is associated with the first RAT. When the terminal device sends the first signal, the terminal device itself decides to enable the first RAT, notifies the network device to enable the first RAT via the first signal, and / or the first signal is associated with the first RAT.

[0125] In some implementations, the first signal is received, and the first signal includes at least one or more of the following: a synchronization signal and a physical broadcast channel block (SSB); a primary synchronization signal (PSS); a secondary synchronization signal (SSS); and a physical broadcast channel (PBCH).

[0126] In this embodiment, when the terminal device receives the first signal, the first signal received by the terminal device can be one or more of SSB, PSS, SSS, and PBCH. In other words, the terminal device can receive a first signal as a first synchronization signal, and the first synchronization signal can include one or more of SSB of the NR system, PSS, SSS, and PBCH of the NR / LTE system. That is, the first signal received by the terminal device can be a synchronization signal under 5G network, 4G network, 3G network, or 2G network.

[0127] In some implementations, the Minimum System Information (MIB) in the first signal indicates that the first RAT is enabled, and / or the first signal is associated with the first RAT; or, the PBCH payload in the first signal indicates that the first RAT is enabled, and / or the first signal is associated with the first RAT.

[0128] In this embodiment, when the first signal received by the terminal device is one or more of the SSB, PSS, SSS, and PBCH signals in the NR / LTE system, the first RAT can be enabled and / or the first signal can be associated with the first RAT through the idle field in the above signal; the first RAT can also be enabled and / or the first signal can be associated with the first RAT through the channel coding sequence in the above signal.

[0129] For example, the first signal may include first indication information for indicating that the first RAT is enabled, and / or, the first signal is associated with the first RAT. When the terminal device receives the first synchronization signal, the first indication information may be a first field in the aforementioned signal, such as an idle bit in the MIB; or, the first indication information may also be a first coded sequence in the aforementioned signal, such as a Physical Broadcast Channel payload (PBCH payload).

[0130] It should be noted that, in the embodiments of the present invention, the first signal instructing the first RAT to enable one or more of SSB, PSS, SSS, and PBCH in the NR / LTE system, and / or the way the first signal is associated with the first RAT is not limited to the above two, but may also include other ways, which will not be elaborated here.

[0131] As an example, Figure 8This is a schematic diagram of a synchronization signal reception according to an embodiment of the present invention; as shown. Figure 8 As shown, when the first synchronization signal that enables the first RAT is indicated by display fields, sequence values, channel coding, etc., and is the synchronization signal of the SSB of the NR system or the PBCH of the LTE system, the terminal device can also receive a second synchronization signal at a frequency domain and / or time domain location different from the first synchronization signal (e.g., the original synchronization grid of 5G or 4G, etc.) (e.g., the synchronization grid newly designed based on the 6G system). The second synchronization signal can be the SSB newly designed for 6G, or other synchronization signals used for initial search.

[0132] In some implementations, the first signal is received as downlink control information (DCI) or as paging information; the first signal includes a first feature indicating that a first RAT is enabled, or the first signal is associated with the first RAT.

[0133] In this embodiment, when the terminal device receives a first signal, the first signal received by the terminal device can be downlink control information (DCI) in a 6G system, or paging information in a 6G system (i.e., a signal that can carry paging information). When the first signal received by the terminal device is DCI or paging information, a first feature in the first signal can be used to indicate that the first RAT is enabled, or to indicate that the first signal is associated with the first RAT. The paging information can also be referred to as a paging message or paging.

[0134] It should be noted that the embodiments of the present invention can determine the association of the first signal with the 6G network in an explicit or implicit manner. Specifically, when there is explicit relevant indication information in the first signal, such as the value of the short message indication field or the bits of the short message field, it can be determined that the first signal is associated with the 6G network, that is, it is determined that the first feature is used to indicate the first RAT enable, or to indicate that the first signal is associated with the first RAT; or, the association of the first signal with the first RAT can be indirectly known through implicit information in the first signal (such as resource location, identifier, etc.).

[0135] In some implementations, the first feature is at least one or more of the following: a Control Channel Element (CCE) resource or index corresponding to the first signal; a Radio Network Temporary Identifier (RNTI) of the first signal; a first value of the Short Message Indication field of the first signal; a first bit in the Short Message Indication field of the first signal; and a first field of the first signal.

[0136] In this embodiment, when the first signal received by the terminal device is DCI or paging information, the first feature can be indicated by the control channel element (CCE) resource or index corresponding to the first signal, the radio network temporary identifier (RNTI), the first value of the short message indication field, the first bit in the short message indication field, or one or more of the first fields, to indicate that the first RAT is enabled, or to indicate that the first signal is associated with the first RAT.

[0137] As an example, when the first signal received by the terminal device is paging information (or paging DCI), the first feature in the paging DCI may specifically be one or more of the following:

[0138] 1) The CCE resource in the paging DCI may specifically be the offset value included in the CCE ordering of the paging DCI;

[0139] 2) The scrambling RNTI in the paging DCI can specifically be the offset value included in the RNTI of the paging DCI;

[0140] 3) The first value in the short message indication field of the paging DCI can specifically be the "00" value in the short message indication field of the paging DCI;

[0141] 4) The first bit in the short message field of the paging DCI may specifically be one bit or more bits in the 5th to 8th bits of the short message indication field of the paging DCI;

[0142] 5) The first field in the paging DCI may be a field different from the short message field or the short message indication field, specifically it may be some newly added fields in the paging DCI.

[0143] It should be noted that, in the embodiments of the present invention, when the first signal is DCI or paging information, the content of the first feature used to indicate the first RAT to be enabled and / or associated with the first RAT is not limited to the above-mentioned types, but may also include other methods, which will not be elaborated on here.

[0144] In this embodiment, based on the first feature composed of one or more of the above-mentioned paging DCI, it is possible to enable the first RAT and / or to indicate that the DCI or paging message is associated with the first RAT.

[0145] In some implementations, the first signal is sent as an uplink control signal; the first signal includes a second feature indicating that a first RAT is enabled, or the first signal is associated with the first RAT.

[0146] In this embodiment, when the terminal device sends a first signal, the first signal sent by the terminal device can be an uplink control signal in a 6G system, such as a 6G Physical Uplink Control Channel (PUCCH) signal. When the first signal sent by the terminal device is an uplink control signal, the first RAT can be enabled or the first signal can be associated with the first RAT through the second feature in the first signal.

[0147] In some implementations, the second feature is at least one or more of the following: a first cyclic shift value; a first cyclic shift difference; and a first coded bit.

[0148] In this embodiment, when the first signal sent by the terminal device is an uplink control signal in a 6G system, one or more of the first cyclic shift value, the first cyclic shift difference value, and the first coded bits of the first signal can be used as a second feature to indicate that the first RAT is enabled, or to indicate that the first signal is associated with the first RAT.

[0149] Specifically, when the first signal sent by the terminal device is PUCCH, the format used to transmit uplink control information varies depending on the code division multiplexing (CDM) method used, and the second feature of the PUCCH is also different. Specifically, it can be one or more of the first cyclic shift value, the first cyclic shift difference, and the first coded bit.

[0150] As an example, when the first signal is a cyclic shift-based PUCCH, the format of the corresponding transmission uplink control information can be PUCCH format 0 / 1, and the second feature can be one or more of the first cyclic shift value, cyclic shift difference, and first coded bit of the PUCCH. For example, it can indicate the first RAT enable based on a specific cyclic shift value, or indicate that the first signal is associated with the first RAT.

[0151] For example, a 1-bit Hybrid Automatic Repeat Request (HARQ) can be indicated based on a cyclic shift value of 1 / 7, 2 / 8, or 3 / 9; a 2-bit HARQ can be indicated based on a cyclic shift value of 1 / 4 / 7 / 10, or 2 / 5 / 8 / 11; and a 1-bit HARQ+Selective Repeat (SR) can be indicated based on a cyclic shift value of 1 / 4 / 7 / 10, or 2 / 5 / 8 / 11.

[0152] As another example, when the first signal is a coded PUCCH, the format of the corresponding transmission uplink control information can be PUCCH format 1 / 2 / 3, and the second feature can also be one or more of the first cycle shift value, cycle shift difference value, and first coded bit of the PUCCH. For example, the first RAT can be enabled according to a specific cycle shift value, or the first signal can be associated with the first RAT.

[0153] Figure 9 This is a schematic diagram illustrating the transmission timing of the first signal according to an embodiment of the present invention; as shown... Figure 9 As shown, the first signal can occupy one of the multiple shared transmission opportunities of 6G and LTE / NR as the transmission opportunity of the first signal, so as to determine the indication information according to the explicit or implicit means, through which the first RAT is enabled, or the first signal is associated with the first RAT, that is, through the indication information, the 6G network is associated.

[0154] In some embodiments, the method further includes: receiving a second signal, the second signal including first configuration information; wherein the first configuration information includes one or more of a first subcarrier spacing, a first frame structure, and a first transmission pattern, and the first configuration information is associated with one or more of a channel sounding reference signal (SRS), a channel state information reference signal (CSI-RS), and a demodulation reference signal (DM-RS).

[0155] In this embodiment, the terminal device may also receive a second signal, which includes a channel measurement reference signal in a 6G system and first configuration information for one or more reference signals associated with downlink or uplink transmission. The first configuration information represents the transmission resources of the aforementioned signals, and may specifically include one or more of a first subcarrier spacing, a first frame structure, and a first transmission pattern.

[0156] For example, the channel measurement reference signal in the 6G system may be SRS or CSI-RS; the reference signal associated with downlink or uplink transmission in the 6G system may be DM-RS.

[0157] It is understood that the second signal may be received by the terminal device after receiving a first signal indicating that the first RAT is enabled, or indicating that the first RAT is associated; or it may be received separately if the terminal device does not receive the first signal indicating that the first RAT is enabled, or indicating that the first RAT is associated.

[0158] It should be noted that the second signal used to carry the first configuration information can be a signal associated with the second RAT, that is, the second signal can be a signal in the LTE or NR system, or a signal in the 5G, 4G, 3G, or 2G system. The first configuration information can be SIB1 in the LTE or NR system. In other words, embodiments of the present invention can indicate the transmission resources of signals such as SRS, CSI-RS, and DM-RS in the aforementioned 6G system by reusing LTE SIB1 or NR SIB1.

[0159] In some embodiments, the method further includes: receiving a third signal, the third signal including second configuration information; wherein the second configuration information includes one or more of a second subcarrier spacing, a second frame structure, and a second transmission pattern, and the second configuration information is associated with one or more of the following: uplink or downlink partial carrier bandwidth (BWP), uplink or downlink carrier, uplink data transmission, and downlink data transmission.

[0160] In this embodiment, after receiving a first signal indicating that the first RAT is enabled, or indicating the association with the first RAT, the terminal device may also receive a third signal. The third signal includes second configuration information for one or more of the following: uplink or downlink partial carrier bandwidth (BWP), uplink or downlink carrier, uplink data transmission, and downlink data transmission. The second configuration information represents the current LTE or NR transmission resources, and may specifically include one or more of the following: second subcarrier spacing, second frame structure, and second transmission pattern.

[0161] For example, the second subcarrier spacing can be the subcarrier spacing of uplink or downlink BWP, or uplink or downlink carriers, such as the subcarrier spacing of LTE / NR; the second frame structure can be the frame structure of uplink or downlink BWP, or uplink or downlink carriers, such as the frame structure of LTE / NR; the second transmission pattern can be the transmission pattern of a reference signal, such as the reference signal transmission pattern in LTE / NR, specifically including one or more of the following: resource information such as time domain, frequency domain, CDM group, and port resource configuration used by the terminal in LTE / NR; resource information such as time domain, frequency domain, frequency hopping, and port resource configuration used by the terminal in SRS; resource information such as mapping type, single symbol or double symbol mode, configuration type, and port resource configuration used by the terminal in DM-RS PDSCH; and port resource enabling status of the reference signal pattern.

[0162] It should be noted that the second signal and the third signal can be different or the same signal. In other words, the terminal device in this embodiment of the invention can receive a second signal including first configuration information and a third signal including second configuration information after receiving the first signal; or it can receive a second signal (or a third signal) that includes both first and second configuration information after receiving the first signal.

[0163] In some embodiments, the method further includes: determining transmission resources for a fourth signal based on the first configuration information, wherein the fourth signal is one or more of SRS, CSI-RS, and DM-RS; determining transmission resources for the uplink data transmission and / or the downlink data transmission based on the second configuration information; wherein the transmission resources for the uplink data transmission and / or the downlink data transmission are transmission resources indicated in the second configuration information that do not overlap with the transmission resources of the fourth signal; or, the transmission resources for the uplink data transmission and / or the downlink data transmission are transmission resources indicated in the second configuration information whose time interval with the transmission resources of the fourth signal is greater than and / or equal to a first time interval.

[0164] In this embodiment, after obtaining first configuration information and second configuration information based on the received second signal and / or third signal, the terminal device determines the transmission resources of one or more fourth signals among SRS, CSI-RS and DM-RS according to the first configuration information, and determines the transmission resources for uplink data transmission and / or downlink data transmission according to the second configuration information, thereby realizing uplink data transmission and / or downlink data transmission based on the transmission resources for uplink data transmission and / or downlink data transmission.

[0165] It is understood that since the first configuration information in the second signal received by the terminal may include the transmission resources of one or more signals among SRS, CSI-RS, and DM-RS in the 6G system, the terminal device can determine the transmission resources of one or more signals among SRS, CSI-RS, and DM-RS, i.e., the transmission resources of the fourth signal, based on the first configuration information after obtaining it. In other words, the terminal device can determine the transmission of 6GSRS and / or the reception of 6GCSI-RS and DM-RS based on the first configuration information.

[0166] Furthermore, after determining the transmission resources for sending or receiving the fourth signal based on the first configuration information, the transmission resources for uplink data transmission and / or downlink data transmission after the fourth signal is sent or received can be determined based on the first configuration information and the second configuration information.

[0167] Figure 10 This is a schematic diagram of transmission resources for uplink and / or downlink data transmission according to an embodiment of the present invention; as shown. Figure 10 As shown, the transmission resources for uplink data transmission and / or downlink data transmission in this embodiment of the invention can be of two types, specifically:

[0168] In the first case, the transmission resources for the uplink data transmission and / or downlink data transmission can be transmission resources that do not overlap with the transmission resources of the fourth signal (i.e., the transmission resources indicated by the first configuration information) among the transmission resources indicated by the second configuration information.

[0169] For example, such as Figure 10 As shown in a, the non-overlapping transmission resources can specifically be all resource blocks (RBs) or resource elements (REs) in the time domain resources of the transmission resources indicated by the second configuration information that do not overlap completely or partially with the time domain resources of the transmission resources indicated by the first configuration information.

[0170] Secondly, the transmission resources for the uplink data transmission and / or downlink data transmission can also be the transmission resources indicated by the second configuration information, wherein the time interval between the transmission resources of the fourth signal (i.e., the transmission resources indicated by the first configuration information) and the transmission resources of the fourth signal is not less than the first time interval.

[0171] For example, such as Figure 10As shown in b, the transmission resources with a time interval not less than the first time interval can specifically be the transmission resources indicated by the second configuration information, where the time interval between them and the transmission resources indicated by the first configuration information is not less than the first time interval RB or RE. That is, when the transmission resources in the first configuration information do not fill the entire symbol, resources within the same symbol cannot be used as transmission resources for uplink data transmission and / or downlink data transmission.

[0172] It should be noted that when the fourth signal is associated with uplink and / or downlink data transmission, the difference between the fourth signal and the average energy per resource element (EPRE) of the uplink and / or downlink data transmissions can be a fixed value. For example, it is -3 dB for Type 1 and -4.77 dB for Type 2.

[0173] In this embodiment, the terminal device can determine whether uplink and / or downlink data transmission is required based on determined transmission resources used for uplink and / or downlink data transmission by receiving explicit or implicit indication information. Specifically, the terminal device can determine this based on received scheduling information (e.g., DCI or PDCCH) instructing the terminal device whether to perform uplink and / or downlink data transmission on transmission resources used for uplink and / or downlink data transmission; or, if the terminal device does not find any relevant indications for uplink and / or downlink data transmission in the received system configuration information, it can determine that uplink and / or downlink data transmission is not required on the transmission resources used for uplink and / or downlink data transmission.

[0174] In some embodiments, the method further includes: receiving a fifth signal, the fifth signal being used to indicate the first time interval; and / or, the first time interval being a preset value.

[0175] In this embodiment, the terminal device can obtain a first time interval for comparing the time interval between the second configuration information and the transmission resources indicated by the first configuration information by receiving a fifth signal, that is, the first time interval is pre-configured by the network device; or, the first time interval for comparing the time interval between the second configuration information and the transmission resources indicated by the first configuration information is a predefined value.

[0176] This invention provides a signal transmission method that is applied to network devices. Figure 11 This is a flowchart illustrating the signal transmission method according to an embodiment of the present invention. Figure 2 ;like Figure 11 As shown, the method includes:

[0177] Step 201: Send or receive a first signal, the first signal indicating that a first RAT is enabled, and / or, the first signal is associated with the first RAT; wherein, the first RAT is a 6G network RAT, or, the first RAT is different from a second RAT; the second RAT is a RAT of any of the following networks: 5G network, 4G network, 3G network, 2G network.

[0178] Here, the network device in the embodiments of the present invention can be a Radio Access Network (RAN) point (or device) that connects a terminal to a wireless network, also known as a base station. It can be a RAT that supports 6G networks or a RAT that is different from 6G networks (e.g., 5G, 4G, 3G, 2G networks). It can also be an evolved NodeB (eNB or eNodeB) in an LTE system, or a radio controller in a Cloud RAN (CRAN) scenario. Alternatively, the network device can be a relay station, access point, vehicle-mounted device, wearable device, or a network device in a 5G network or a network device in a future evolved wireless communication network. It can also be one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node that constitutes a next-generation base station (gNB or ng-eNB) or transmission point, such as a baseband unit (BBU) or a distributed unit (DU). The embodiments of this application are not limited to this.

[0179] In some implementations, the first signal is transmitted, and the first signal includes at least one or more of the following: a synchronization signal and a physical broadcast channel block (SSB); a primary synchronization signal (PSS); a secondary synchronization signal (SSS); and a physical broadcast channel (PBCH).

[0180] In this embodiment, when the network device sends a first signal, the first signal sent by the network device can be one or more synchronization signals selected from SSB, PSS, SSS, and PBCH. In other words, the network device can send a first signal as a first synchronization signal to the terminal device, and the first synchronization signal can include one or more of the following: SSB of the NR system, PSS, SSS, and PBCH of the NR / LTE system. That is, the first signal sent by the network device to the terminal device can be a synchronization signal under 5G network, 4G network, 3G network, or 2G network.

[0181] In some implementations, the minimum system information (MIB) in the first signal indicates that the first RAT is enabled, and / or the first signal is associated with the first RAT; or, the PBCH payload in the first signal indicates that the first RAT is enabled, and / or the first signal is associated with the first RAT.

[0182] In this embodiment, when the first signal sent by the network device to the terminal device is one or more of the SSB, PSS, SSS, and PBCH signals in the NR / LTE system, the first RAT can be enabled and / or the first signal can be associated with the first RAT through the idle field in the above signal; the first RAT can also be enabled and / or the first signal can be associated with the first RAT through the channel coding sequence in the above signal.

[0183] For example, the first signal may include first indication information for indicating that the first RAT is enabled, and / or, the first signal is associated with the first RAT. When the network device sends the first synchronization signal, the first indication information may be a first field in the aforementioned signal, such as an idle bit in the MIB; or, the first indication information may also be a first encoded sequence in the aforementioned signal, such as a PBCH payload.

[0184] It should be noted that, in the embodiments of the present invention, the first signal instructing the first RAT to enable one or more of SSB, PSS, SSS, and PBCH in the NR / LTE system, and / or the way the first signal is associated with the first RAT is not limited to the above two, but may also include other ways, which will not be elaborated here.

[0185] In some implementations, the first signal is transmitted as Downlink Control Information (DCI) or as Paging Information; the first signal includes a first feature indicating that a first RAT is enabled, or the first signal is associated with the first RAT.

[0186] In this embodiment, when the network device sends a first signal, the first signal sent by the network device can be DCI in a 6G system or paging information in a 6G system (i.e., a signal that can carry paging information). When the first signal sent by the network device is DCI or paging information, the first RAT can be enabled by the first feature in the first signal, or the first signal can be associated with the first RAT.

[0187] It should be noted that the embodiments of the present invention can determine the first feature in the first signal in an explicit or implicit manner. Specifically, when the first feature exists in the first signal, it can be determined that the first feature is used to indicate the first RAT to be enabled, or to indicate that the first signal is associated with the first RAT; if the first feature does not exist in the first signal, the first feature cannot be determined.

[0188] In some implementations, the first feature is at least one or more of the following: the Control Channel Element (CCE) resource or index of the first signal; the Radio Network Temporary Identifier (RNTI) of the first signal; the first value of the Short Message Indication field of the first signal; the first bit in the Short Message Indication field of the first signal; and the first field of the first signal.

[0189] In this embodiment, when the first signal sent by the network device is a DCI or paging information, the first feature can be indicated by the control channel element (CCE) resource or index corresponding to the first signal, the radio network temporary identifier (RNTI), the first value of the short message indication field, the first bit in the short message indication field, or one or more of the first fields, to indicate that the first RAT is enabled, or to indicate that the first signal is associated with the first RAT.

[0190] As an example, when the first signal sent by the network device is a paging message (or paging DCI), the first feature in the paging DCI may specifically be one or more of the following:

[0191] 1) The CCE resource in the paging DCI may specifically be the offset value included in the CCE ordering of the paging DCI;

[0192] 2) The scrambling RNTI in the paging DCI can specifically be the offset value included in the RNTI of the paging DCI;

[0193] 3) The first value in the short message indication field of the paging DCI can specifically be the "00" value in the short message indication field of the paging DCI;

[0194] 4) The first bit in the short message field of the paging DCI may specifically be one bit or more bits in the 5th to 8th bits of the short message indication field of the paging DCI;

[0195] 5) The first field in the paging DCI may be a field different from the short message field or the short message indication field, specifically it may be some newly added fields in the paging DCI.

[0196] It should be noted that, in the embodiments of the present invention, when the first signal is DCI or paging information, the content of the first feature used to indicate the first RAT to be enabled and / or associated with the first RAT is not limited to the above-mentioned types, but may also include other methods, which will not be elaborated on here.

[0197] In this embodiment, based on the first feature composed of one or more of the above-mentioned paging DCI, it is possible to enable the first RAT and / or to indicate that the DCI or paging message is associated with the first RAT.

[0198] In some implementations, the first signal is received as an uplink control signal; the first signal includes a second feature indicating that a first RAT is enabled, or the first signal is associated with the first RAT.

[0199] In this embodiment, when the network device receives a first signal, the first signal received by the network device can be an uplink control signal in a 6G system, such as a 6G PUCCH signal. When the first signal received by the network device is an uplink control signal, the first RAT can be enabled or associated with the first RAT through the second feature in the first signal.

[0200] It should be noted that the embodiments of the present invention can determine the second feature in the first signal in an explicit or implicit manner. Specifically, when the second feature exists in the first signal, it can be determined that the second feature is used to indicate the first RAT to be enabled, or to indicate that the first signal is associated with the first RAT; if the second feature does not exist in the first signal, the second feature cannot be determined.

[0201] In some implementations, the second feature is at least one or more of the following: a first cyclic shift value; a first cyclic shift difference; and a first coded bit.

[0202] In this embodiment, when the first signal received by the network device is an uplink control signal in a 6G system, one or more of the first cyclic shift value, the first cyclic shift difference value, and the first coded bits of the first signal can be used as a second feature to indicate that the first RAT is enabled, or to indicate that the first signal is associated with the first RAT.

[0203] Specifically, when the first signal received by the network device is PUCCH, the second feature of the PUCCH will also be different depending on the CDM method used and the format used to transmit uplink control information. Specifically, it can be one or more of the first cyclic shift value, the first cyclic shift difference value, and the first coded bit.

[0204] As an example, when the first signal is a cyclic shift-based PUCCH, the format of the corresponding transmission uplink control information can be PUCCH format 0 / 1, and the second feature can be one or more of the first cyclic shift value, cyclic shift difference, and first coded bit of the PUCCH. For example, it can indicate the first RAT enable based on a specific cyclic shift value, or indicate that the first signal is associated with the first RAT.

[0205] For example, a 1-bit HARQ can be indicated based on a cyclic shift value of 1 / 7, or 2 / 8, or 3 / 9; a 2-bit HARQ can be indicated based on a cyclic shift value of 1 / 4 / 7 / 10, or 2 / 5 / 8 / 11; and a 1-bit HARQ+SR can be indicated based on a cyclic shift value of 1 / 4 / 7 / 10, or 2 / 5 / 8 / 11.

[0206] As another example, when the first signal is a coded PUCCH, the format of the corresponding transmission uplink control information can be PUCCH format 1 / 2 / 3, and the second feature can also be one or more of the first cycle shift value, cycle shift difference value, and first coded bit of the PUCCH. For example, the first RAT can be enabled according to a specific cycle shift value, or the first signal can be associated with the first RAT.

[0207] In some embodiments, the method further includes: transmitting a second signal, the second signal including first configuration information; wherein the first configuration information includes one or more of a first subcarrier spacing, a first frame structure, and a first transmission pattern, and the first configuration information is associated with one or more of SRS, CSI-RS, and DM-RS.

[0208] In this embodiment, after sending a first signal indicating that the first RAT is enabled, or indicating the association with the first RAT, the network device may also send a second signal. The second signal includes channel measurement reference signals in a 6G system and first configuration information for one or more of the reference signals associated with downlink or uplink transmissions. The first configuration information represents the transmission resources of the aforementioned signals, and may specifically include one or more of a first subcarrier spacing, a first frame structure, and a first transmission pattern.

[0209] For example, the channel measurement reference signal in the 6G system may be SRS or CSI-RS; the reference signal associated with downlink or uplink transmission in the 6G system may be DM-RS.

[0210] It is understood that the second signal may be sent by the network device after sending a first signal indicating that the first RAT is enabled, or indicating that the first RAT is associated; or it may be sent separately if the network device does not send a first signal indicating that the first RAT is enabled, or indicating that the first RAT is associated.

[0211] It should be noted that the second signal used to carry the first configuration information can be a signal associated with the second RAT, that is, the second signal can be a signal in the LTE or NR system, or a signal in the 5G, 4G, 3G, or 2G system. The first configuration information can be SIB1 in the LTE or NR system. In other words, embodiments of the present invention can indicate the transmission resources of signals such as SRS, CSI-RS, and DM-RS in the aforementioned 6G system by reusing LTE SIB1 or NR SIB1.

[0212] In some embodiments, the method further includes: transmitting a third signal, the third signal including second configuration information; wherein the second configuration information includes one or more of a second subcarrier spacing, a second frame structure, and a second transmission pattern, and the second configuration information is associated with one or more of the following: uplink or downlink partial carrier bandwidth (BWP), uplink or downlink carrier, uplink data transmission, and downlink data transmission.

[0213] In this embodiment, after sending a first signal indicating that the first RAT is enabled, or indicating the association with the first RAT, the network device may also send a third signal. The third signal includes second configuration information for one or more of the following: uplink or downlink BWP, uplink or downlink carrier, uplink data transmission, and downlink data transmission. The second configuration information represents the current LTE or NR transmission resources, and may specifically include one or more of the following: a second subcarrier spacing, a second frame structure, and a second transmission pattern.

[0214] For example, the second subcarrier spacing can be the subcarrier spacing of uplink or downlink BWP, or uplink or downlink carriers, such as the subcarrier spacing of LTE / NR; the second frame structure can be the frame structure of uplink or downlink BWP, or uplink or downlink carriers, such as the frame structure of LTE / NR; the second transmission pattern can be the transmission pattern of a reference signal, such as the reference signal transmission pattern in LTE / NR, specifically including one or more of the following: resource information such as time domain, frequency domain, CDM group, and port resource configuration used by the terminal in LTE / NR; resource information such as time domain, frequency domain, hopping, and port resource configuration used by the terminal in SRS; resource information such as mapping type, single symbol or double symbol mode, configuration type, and port resource configuration used by the terminal in DM-RS PDSCH; and port resource enabling status of the reference signal pattern.

[0215] It should be noted that the second signal and the third signal can be different or the same signal. In other words, the network device in this embodiment of the invention can send a second signal including the first configuration information and a third signal including the second configuration information after sending the first signal; or it can send a second signal (or a third signal) that includes both the first and second configuration information after sending the first signal.

[0216] In this embodiment, the network device sends the first configuration information so that the terminal device can determine the transmission resources of one or more signals among SRS, CSI-RS and DM-RS in the 6G system based on the first configuration information, thereby enabling the network device to receive SRS and / or send CSI-RS and DM-RS based on the above transmission resources.

[0217] Furthermore, by sending the first configuration information and the second configuration information, the network device enables the terminal device to determine the transmission resources for uplink and / or downlink data transmission based on the first and second configuration information, so that the terminal device can receive explicit or implicit instructions to perform uplink data transmission and / or downlink data transmission, thereby realizing uplink and / or downlink data transmission based on the transmission resources for uplink and / or downlink data transmission.

[0218] It should be noted that the process by which the terminal device determines the transmission resources of one or more signals among SRS, CSI-RS and DM-RS based on the first configuration information and the second configuration information, as well as the process by which it determines the transmission resources for uplink data transmission and / or downlink data transmission, has been described in detail on the terminal side and will not be elaborated on here.

[0219] In some embodiments, the method further includes sending a fifth signal, the fifth signal being used to indicate a first time interval.

[0220] In this embodiment, the network device sends a fifth signal so that the terminal device can obtain a first time interval for comparing the time interval between the second configuration information and the transmission resources indicated by the first configuration information. That is, the first time interval may be pre-configured by the network device.

[0221] In this embodiment, a first signal different from that of the 6G network is received or transmitted between the terminal device and the network device. The first signal is used to indicate the RAT enable of the 6G network, and / or the first signal is associated with the RAT of the 6G network. A 6G and LTE / NR spectrum sharing design based on coupling is adopted. When the spectrum sharing of 6G transmission signals and NR transmission signals is enabled, the existing channels or signals are reused to the maximum extent, which significantly improves spectrum efficiency and resource utilization, reduces network transmission overhead, and saves network energy consumption.

[0222] Based on this, the present invention also proposes a signal transmission method. Figure 12 This is a flowchart illustrating the signal transmission method according to an embodiment of the present invention. Figure 3 ;like Figure 12 As shown, the method is applied to a terminal device, and the method includes:

[0223] Step 301: Receive a sixth signal; wherein the sixth signal includes third configuration information, the third configuration information being associated with one or more of SSB, SIB1, CSI-RS, Tracking Reference Signal (TRS), DM-RS, PRACH, PUCCH, and SRS.

[0224] Step 302: Receive a seventh signal; wherein the seventh signal includes fourth configuration information, the fourth configuration information includes transmission resources of a first downlink transmission signal, and / or transmission resources of a first uplink transmission signal, the first downlink transmission signal being associated with one or more of PSS, SSS, PBCH, SSB, Low Power Synchronization Signal (LP-SS), PUCCH, PDSCH, and Semi-Persistent Scheduling (SPS) PDSCH, and the first uplink transmission signal being associated with one or more of PRACH, PUCCH, PUSCH, and Configuration Grant (CG) PUSCH.

[0225] The description of the terminal device in this embodiment of the invention has been described in detail above, and will not be repeated here.

[0226] In this embodiment, the terminal device receives a sixth signal including third configuration information. The sixth signal may include transmission resources for downlink signals in the NR or LTE system, and / or transmission resources for uplink signals in the NR or LTE system.

[0227] As an example, the downlink signal transmission resources in the NR or LTE system may include one or more of the following: SSB, SIB1, CSI-RS, Tracking Reference Signal (TRS), and DM-RS transmission resources. Specifically:

[0228] SSB transmission resources can include multiple sets of SSB transmission resources, such as resource configuration information for radio frames and half-frames in different transmission periods; SIB1 transmission resources can include multiple sets of SIB1 transmission resources, such as resource configuration information for different time domains and frequency domains in the transmission period corresponding to SSB; CSI-RS or TRS transmission resources can include multiple sets of CSI-RS or TRS transmission resources, such as resource configuration information for different time domains and frequency domains in different transmission periods, CDM code division multiplexing groups, and port configurations used by the terminal; DM-RS transmission resources can include resource configuration information for DM-RS PDSCH mapping type, single-symbol / double-symbol mode, configuration type, and port configurations used by the terminal.

[0229] As another example, the uplink signal transmission resources in the NR or LTE system may include one or more of the transmission resources of PRACH, PUCCH, and SRS, specifically:

[0230] The transmission resources of PRACH can include multiple sets of PRACH transmission resources, such as resource configuration information such as different time domain configuration indices, frequency domain positions, and frequency domain resource occupancy for different transmission periods; the transmission resources of PUCCH can include multiple sets of PUCCH transmission resources, such as resource configuration information such as different time domains and frequency domains for different transmission periods; the transmission resources of SRS can include multiple sets of SRS transmission resources, such as resource configuration information such as time domain, frequency domain, hopping, and port configuration used by the terminal for different transmission periods.

[0231] It should be noted that the sixth signal may include indication information, which is used to indicate that the first RAT is enabled, and / or the sixth signal is associated with the first RAT. That is, the sixth signal is associated with the 6G network. Based on this, the first configuration information of the sixth signal may be the system information of the 6G system, such as 6G SIB1. That is, the sixth signal can indicate the transmission resources of downlink and / or uplink signals in the NR or LTE system through SIB1 in the 6G system.

[0232] In this embodiment, the terminal device may also receive a seventh signal of the transmission resources of the first downlink transmission signal and / or the first uplink transmission signal.

[0233] The transmission resources of the first downlink transmission signal in the fourth configuration information may include one or more of the transmission resources of the synchronization signal, the transmission resources of the downlink control signal, and the transmission resources of the downlink data transmission in the 6G system; the transmission resources of the first uplink transmission signal in the fourth configuration information may include one or more of the transmission resources of the access signal, the transmission resources of the uplink control signal, and the transmission resources of the uplink data transmission in the 6G system.

[0234] As an example, the transmission resources of the synchronization signal in the 6G system in the first downlink transmission signal may include the transmission patterns of one or more signals selected from 6GPSS, 6G SSS, 6G PBCH, 6G SSB, and Low-Power Synchronization Signal (LP-SS); the transmission resources of the downlink control signal in the 6G system may include the time-domain transmission resources and / or frequency-domain transmission resources corresponding to the 6G PDCCH; the transmission resources of the downlink data transmission in the 6G system may include the time-domain transmission resources and / or frequency-domain transmission resources corresponding to the 6G PDSCH, and / or the 6G semi-persistent scheduling (SPS) PDSCH.

[0235] As another example, the transmission resources of the access signal in the 6G system in the first uplink transmission signal may include time-domain transmission resources and / or frequency-domain transmission resources corresponding to the 6G PRACH; the uplink control signal in the 6G system may include time-domain transmission resources and / or frequency-domain transmission resources corresponding to the 6G PUCCH; the uplink data transmission in the 6G system may include 6G PUSCH, and / or time-domain transmission resources and / or frequency-domain transmission resources corresponding to the 6G Configuration Grant (CG) PUSCH.

[0236] It should be noted that the sixth signal and the seventh signal can be different or the same signal. In other words, the terminal device in this embodiment of the invention can receive a fifth signal including third configuration information and then a seventh signal including fourth configuration information; or it can receive a sixth signal (or a seventh signal) that includes both third and fourth configuration information.

[0237] In some embodiments, the method further includes: determining available / effective transmission resources for the second downlink transmission signal, and / or available / effective transmission resources for the second uplink transmission signal; wherein the available / effective transmission resources for the second downlink transmission signal and / or the second uplink transmission signal are transmission resources indicated in the fourth configuration information that do not overlap with transmission resources indicated in the third configuration information; or, the available / effective transmission resources for the second downlink transmission signal and / or the second uplink transmission signal are transmission resources indicated in the fourth configuration information whose time interval with the transmission resources indicated in the third configuration information is greater than and / or equal to a second time interval.

[0238] In this embodiment, after receiving the sixth signal and the seventh signal, the terminal device can determine the second downlink transmission signal from the first downlink transmission signal based on the sixth signal, that is, determine one or more of the second downlink transmission signals among PSS, SSS, PBCH, SSB, LP-SS, PUCCH, PDSCH, and SPS PDSCH, and / or determine the second uplink transmission signal from the first uplink transmission signal, that is, determine one or more of the second downlink transmission signals among PRACH, PUCCH, PUSCH, and CG PUSCH.

[0239] It should be noted that, in this embodiment of the invention, the terminal device may determine different second downlink transmission signals and / or second uplink transmission signals under different circumstances based on the received sixth and seventh signals, so as to perform resource mapping in the subsequent process of determining the transmission resources of the second downlink transmission signals and / or second uplink transmission signals.

[0240] As an example, the terminal device can determine the second downlink transmission signal and / or the second uplink transmission signal based on the transmission resources of the sixth signal included in the third configuration information included in the sixth signal. Specifically, when the third configuration information includes multiple sets of transmission resources (i.e., transmission resources corresponding to different transmission cycles) for all configurations of downlink signals and / or uplink signals in NR or LTE systems, the terminal device can determine from the first downlink transmission signal that the second downlink transmission signal is a synchronization signal and / or downlink control signal under the 6G system, such as one or more of 6G's PSS, SSS, PBCH, SSB, LP-SS, and PUCCH, and determine from the first uplink transmission signal that the second uplink signal is an access signal under the 6G system, such as 6G PRACH.

[0241] It should be noted that when the third configuration information includes multiple sets of transmission resources (i.e., transmission resources corresponding to different transmission cycles) for all configurations of downlink and / or uplink signals in the NR or LTE system, it can be assumed that when determining the transmission resources of the second downlink transmission signal and / or the second uplink transmission signal, the configuration resources of all signals need to be mapped.

[0242] As another example, the terminal device can determine the second downlink transmission signal and / or the second uplink transmission signal based on the indication information included in the sixth signal. Specifically, when the sixth signal includes indication information for indicating the transmission resources actually enabled in the third configuration information, the terminal device can determine from the first downlink transmission signal that the second downlink transmission signal is downlink data transmission under a 6G system, such as PDSCH and / or SPS PDSCH, and determine from the first uplink signal that the second uplink signal is an uplink control signal and / or uplink data transmission under a 6G system, such as one or more of PUCCH, PUSCH, and CGPUSCH.

[0243] It should be noted that the indication information included in the sixth signal for indicating the transmission resources actually enabled in the third configuration information can be downlink control information. This indication information can also simultaneously indicate the scheduling of uplink / downlink data transmission and / or indicate the effectiveness / activation of uplink control information.

[0244] It should be noted that when the sixth signal includes indication information for the transmission resources actually enabled in the third configuration information, the transmission resources requiring resource mapping can be dynamically indicated when subsequently determining the transmission resources for the second downlink transmission signal and / or the second uplink transmission signal. Furthermore, the indication information for the actually enabled transmission resources can also be sent separately by the network device.

[0245] Figure 13 This is a schematic diagram of the transmission resources indicated by the third configuration information in an embodiment of the present invention; as shown below. Figure 13 As shown, the transmission resources included in the third configuration information in the two methods of determining the second downlink transmission signal and / or the second uplink transmission signal, namely, the multiple sets of transmission resources corresponding to the fully effective NR / LTE downlink signal and / or uplink signal, and the transmission resources corresponding to the effective NR / LTE downlink signal and / or uplink signal dynamically indicated by the network device, can all be reflected in Figure 13 The timeline shown.

[0246] In this embodiment, after determining the second downlink transmission signal and / or the second uplink transmission signal, the terminal device can also determine the transmission resources of the second downlink transmission signal and / or the transmission resources of the second uplink transmission signal based on the third configuration information included in the sixth signal and the fourth configuration information included in the seventh signal, so as to realize downlink transmission and / or uplink transmission.

[0247] In other words, the terminal device can determine the transmission of the second uplink transmission signal of 6G and / or the reception of the second downlink transmission signal of 6G based on the third configuration information and / or the fourth configuration information.

[0248] In this embodiment, the transmission resources of the second downlink transmission signal and / or the second uplink transmission signal may be transmission resources indicated in the fourth configuration information that do not overlap with the transmission resources indicated in the third configuration information; or, the transmission resources of the second downlink transmission signal and / or the second uplink transmission signal may also be transmission resources indicated in the fourth configuration information whose time interval with the transmission resources indicated in the third configuration information is greater than and / or equal to the second time interval.

[0249] It is understood that among the transmission resources indicated in the fourth configuration information, transmission resources that overlap with the transmission resources indicated in the third configuration information, or transmission resources among the transmission resources indicated in the fourth configuration information whose time interval with the transmission resources indicated in the third configuration information is less than the second time interval, can all be determined as invalid (i.e., not transmitted or unavailable) transmission resources.

[0250] In other words, among the transmission resources of the 6G first uplink transmission signal and / or first downlink transmission signal indicated in the fourth configuration information, transmission resources that overlap with the transmission resources of the NR / LTE downlink signal and / or uplink signal indicated in the third configuration information, or transmission resources with a time interval shorter than the second time interval, cannot enable the terminal device to transmit the 6G second uplink transmission signal and receive the 6G second downlink transmission signal.

[0251] In some embodiments, the method further includes: receiving an eighth signal, the eighth signal being used to indicate the second time interval; and / or, the second time interval being a preset value.

[0252] In this embodiment, the terminal device can obtain a second time interval for comparing the time interval between the fourth configuration information and the transmission resources indicated by the third configuration information by receiving the eighth signal, that is, the second time interval is pre-configured by the network device; or, the second time interval for comparing the time interval between the fourth configuration information and the transmission resources indicated by the third configuration information is a predefined value.

[0253] It should be noted that the embodiments of the present invention fully consider that under the future evolution of multiple-input multiple-output (MIMO) architectures (e.g., hybrid beamforming (HBF) or adaptive beamforming (ABF)), the response of simulated beamforming may be relatively slow, easily resulting in small time intervals between transmission resources. Therefore, in addition to determining the transmission resources indicated in the fourth configuration information and the transmission resources indicated in the third configuration information as invalid transmission resources, the embodiments of the present invention can also determine the transmission resources indicated in the fourth configuration information and the transmission resources indicated in the third configuration information as invalid transmission resources if the time interval between them is less than the second time interval.

[0254] Figure 14 This is a schematic diagram of invalid transmission resources according to an embodiment of the present invention; as shown. Figure 14 As shown, among the transmission resources of the first downlink transmission signal and / or the first uplink transmission signal indicated in the fourth configuration information, transmission resources that overlap with the transmission resources of the NR / LTE downlink signal and / or uplink signal indicated in the third configuration information, or whose time interval between them is less than the second time interval, are considered invalid transmission resources.

[0255] It should be noted that, in this embodiment of the invention, the invalid transmission resources determined may be different for different second downlink transmission signals and second uplink transmission signals.

[0256] For example, when the second downlink transmission signal and / or the second uplink transmission signal determined by the terminal device is one or more of a synchronization signal, an access signal, an uplink control signal, and a downlink control signal, the invalid transmission resource corresponding to the above signal may be a transmission opportunity in the transmission resources of the first uplink transmission signal and / or the first downlink transmission signal indicated in the fourth configuration information that is the same in the time domain and / or frequency domain as the transmission resources of the downlink signal and / or the uplink signal of NR / LTE indicated in the third configuration information, or a transmission opportunity in which the time interval of the transmission resources of the downlink signal and / or the uplink signal of NR / LTE indicated in the third configuration information is less than the second time interval.

[0257] When the second downlink transmission signal and / or the second uplink transmission signal determined by the terminal device is one or more of uplink data transmission, downlink data transmission, uplink control signal, and downlink control signal, the invalid transmission resource corresponding to the above signal may be a resource element (e.g., RB, RE) that is the same in time domain and / or frequency domain as the transmission resource of the downlink signal and / or uplink signal of NR / LTE indicated in the third configuration information, or a resource element whose time interval with the transmission resource of the downlink signal and / or uplink signal of NR / LTE indicated in the third configuration information is less than the second time interval.

[0258] In this embodiment, the specific methods for determining the corresponding transmission resources for the different second downlink transmission signals and second uplink transmission signals are also different.

[0259] As an example, when the second downlink transmission signal and / or the second uplink transmission signal determined by the terminal device is one or more of a synchronization signal, an access signal, an uplink control signal, and a downlink control signal:

[0260] 1) Regarding synchronization signals: The terminal device can determine the first mapping relationship between the transmission resources of the access signals included in the fourth configuration information and the transmission resources of other first downlink transmission signals and first uplink transmission signals, based on the index corresponding to the actual transmission of the synchronization signals in the transmission resources indicated by the network device in the fourth configuration information, thereby obtaining the transmission resources corresponding to the synchronization signals (e.g., 6G PSS, SSS, PBCH, SSB) as the second downlink transmission signals.

[0261] Alternatively, the terminal device can determine the first mapping relationship between the transmission resources of the access signal and / or the transmission resources of the reference signal included in the fourth configuration information, based on the index of the synchronization signal (excluding invalid transmission resources) indicated in the fourth configuration information, thereby obtaining the transmission resources corresponding to the synchronization signal (e.g., PSS, SSS, PBCH, SSB of 6G) as the second downlink transmission signal.

[0262] The first mapping relationship can represent the correspondence between each beam index in the synchronization signal and each RB in the transmission resources of the access signal and other first downlink transmission signals and first uplink transmission signals, excluding invalid transmission resources.

[0263] 2) For access signals: The terminal device can first determine the second mapping relationship between the transmission resources of the synchronization signal and the access signal indicated in the fourth configuration information, and then after determining the invalid transmission resources, exclude the invalid transmission resources from the second mapping relationship to obtain the transmission resources corresponding to the access signal (e.g., 6G PRACH) as the second uplink transmission signal.

[0264] The second mapping relationship can represent the correspondence between each beam index in the access signal and each RB in the transmission resources of the synchronization signal, including invalid transmission resources.

[0265] Alternatively, the terminal device may first identify invalid transmission resources, and then, based on the transmission resources other than invalid transmission resources corresponding to the access signal indicated in the fourth configuration information, determine the third mapping relationship between the transmission resources and the synchronization signal included in the fourth configuration information, thereby obtaining the transmission resources corresponding to the access signal (e.g., 6G PRACH) as the second uplink transmission signal.

[0266] The third mapping relationship can represent the correspondence between each beam index in the access signal and each RB in the transmission resources of the synchronization signal, excluding invalid transmission resources.

[0267] 3) For downlink control signals or uplink control signals: The terminal device can first determine the fourth mapping relationship between the transmission resources of the downlink control signal or uplink control signal and the synchronization signal indicated in the fourth configuration information, and then, after determining the invalid transmission resources, exclude the invalid transmission resources from the fourth mapping relationship, thereby obtaining the transmission resources corresponding to the downlink control signal or uplink control signal (e.g., 6GPDCCH, 6G PUCCH) as the second uplink transmission signal.

[0268] The fourth mapping relationship can represent the correspondence between each beam index in the downlink control signal or uplink control signal and each RB in the transmission resources of the synchronization signal, including invalid transmission resources.

[0269] Alternatively, the terminal device may first identify invalid transmission resources, and then, based on the transmission resources other than invalid transmission resources corresponding to the downlink control signal or uplink control signal indicated in the fourth configuration information, determine the fifth mapping relationship between the transmission resources and the synchronization signal included in the fourth configuration information, thereby obtaining the transmission resources corresponding to the downlink control signal or uplink control signal (e.g., 6G PDCCH, 6GPUCCH) that serves as the second uplink transmission signal.

[0270] The fifth mapping relationship can represent the correspondence between each beam index in the downlink control signal or uplink control signal and each RB in the transmission resources of the synchronization signal, excluding invalid transmission resources.

[0271] As another example, when the second downlink transmission signal and / or the second uplink transmission signal is a downlink control signal or an uplink control signal, the terminal device can first determine the invalid transmission resources, and then, according to the transmission resources other than the invalid transmission resources corresponding to the downlink control signal or uplink control signal indicated in the fourth configuration information, set the resource unit index (for example, using the mapping order of one or more of the CCE sequence number, Resource-Element Group (REG) sequence number, RB sequence number, and RE sequence number), or perform rate matching, so as to obtain the transmission resources corresponding to the downlink control signal or uplink control signal (e.g., 6G PDCCH, 6G PUCCH) that is the second uplink transmission signal.

[0272] In this embodiment, after determining the transmission resources of the second downlink transmission signal and / or the second uplink transmission signal, the terminal device can receive the second downlink transmission signal and / or send the second uplink transmission signal on the transmission resources of the second downlink transmission signal.

[0273] This invention also proposes a signal transmission method, which is applied to network devices. Figure 15 This is a flowchart illustrating the signal transmission method according to an embodiment of the present invention. Figure 4 ;like Figure 15 As shown, the method includes:

[0274] Step 401: Send a sixth signal; wherein the sixth signal includes third configuration information, which is associated with one or more of SSB, SIB1, CSI-RS, Tracking Reference Signal (TRS), DM-RS, PRACH, PUCCH, and SRS.

[0275] Step 402: Send a seventh signal; wherein the seventh signal includes fourth configuration information, the fourth configuration information includes transmission resources of a first downlink transmission signal, and / or transmission resources of a first uplink transmission signal, the first downlink transmission signal being associated with one or more of PSS, SSS, PBCH, SSB, Low Power Synchronization Signal (LP-SS), PUCCH, PDSCH, and Semi-Persistent Scheduling (SPS) PDSCH, and the first uplink transmission signal being associated with one or more of PRACH, PUCCH, PUSCH, and Configuration Grant (CG) PUSCH.

[0276] The network device described in this embodiment of the invention has been described in detail above, and will not be repeated here.

[0277] In this embodiment, the network device sends a sixth signal including third configuration information. The sixth signal may include transmission resources for downlink signals in the NR or LTE system, and / or transmission resources for uplink signals in the NR or LTE system.

[0278] As an example, the downlink signal transmission resources in the NR or LTE system may include one or more of the following: SSB, SIB1, CSI-RS, Tracking Reference Signal (TRS), and DM-RS transmission resources. Specifically:

[0279] SSB transmission resources can include multiple sets of SSB transmission resources, such as resource configuration information for radio frames and half-frames in different transmission periods; SIB1 transmission resources can include multiple sets of SIB1 transmission resources, such as resource configuration information for different time domains and frequency domains in the transmission period corresponding to SSB; CSI-RS or TRS transmission resources can include multiple sets of CSI-RS or TRS transmission resources, such as resource configuration information for different time domains and frequency domains in different transmission periods, CDM code division multiplexing groups, and port configurations used by the terminal; DM-RS transmission resources can include resource configuration information for DM-RS PDSCH mapping type, single-symbol / double-symbol mode, configuration type, and port configurations used by the terminal.

[0280] As another example, the uplink signal transmission resources in the NR or LTE system may include one or more of the transmission resources of PRACH, PUCCH, and SRS, specifically:

[0281] The transmission resources of PRACH can include multiple sets of PRACH transmission resources, such as resource configuration information such as different time domain configuration indices, frequency domain positions, and frequency domain resource occupancy for different transmission periods; the transmission resources of PUCCH can include multiple sets of PUCCH transmission resources, such as resource configuration information such as different time domains and frequency domains for different transmission periods; the transmission resources of SRS can include multiple sets of SRS transmission resources, such as resource configuration information such as time domain, frequency domain, hopping, and port configuration used by the terminal for different transmission periods.

[0282] It should be noted that the sixth signal may include indication information, which is used to indicate that the first RAT is enabled, and / or the sixth signal is associated with the first RAT. That is, the sixth signal is associated with the 6G network. Based on this, the first configuration information of the sixth signal may be the system information of the 6G system, such as 6G SIB1. That is, the sixth signal can indicate the transmission resources of downlink and / or uplink signals in the NR or LTE system through SIB1 in the 6G system.

[0283] In this embodiment, the network device may also send a seventh signal of the transmission resources of the first downlink transmission signal and / or the first uplink transmission signal.

[0284] The transmission resources of the first downlink transmission signal in the fourth configuration information may include one or more of the transmission resources of the synchronization signal, the transmission resources of the downlink control signal, and the transmission resources of the downlink data transmission in the 6G system; the transmission resources of the first uplink transmission signal in the fourth configuration information may include one or more of the transmission resources of the access signal, the transmission resources of the uplink control signal, and the transmission resources of the uplink data transmission in the 6G system.

[0285] As an example, the transmission resources of the synchronization signal in the 6G system in the first downlink transmission signal may include the transmission patterns of one or more signals selected from 6GPSS, 6G SSS, 6G PBCH, 6G SSB, and Low-Power Synchronization Signal (LP-SS); the transmission resources of the downlink control signal in the 6G system may include the time-domain transmission resources and / or frequency-domain transmission resources corresponding to the 6G PDCCH; the transmission resources of the downlink data transmission in the 6G system may include the time-domain transmission resources and / or frequency-domain transmission resources corresponding to the 6G PDSCH, and / or the 6G semi-persistent scheduling (SPS) PDSCH.

[0286] As another example, the transmission resources of the access signal in the 6G system in the first uplink transmission signal may include time-domain transmission resources and / or frequency-domain transmission resources corresponding to the 6G PRACH; the uplink control signal in the 6G system may include time-domain transmission resources and / or frequency-domain transmission resources corresponding to the 6G PUCCH; the uplink data transmission in the 6G system may include 6G PUSCH, and / or time-domain transmission resources and / or frequency-domain transmission resources corresponding to the 6G Configuration Grant (CG) PUSCH.

[0287] It should be noted that the sixth signal and the seventh signal can be different or the same signal. In other words, the network device in this embodiment of the invention can send a sixth signal including third configuration information and then send a seventh signal including fourth configuration information; or it can send a sixth signal (or a seventh signal) that includes both third and fourth configuration information.

[0288] In this embodiment, the network device sends a sixth signal including third configuration information and a seventh signal including fourth configuration information so that the terminal device can determine one or more second downlink transmission signals, including 6G synchronization signal, downlink control signal, and downlink data transmission, and / or one or more second uplink transmission signals, including 6G access signal, uplink control signal, and uplink data transmission, based on the sixth signal.

[0289] Furthermore, the terminal device can also determine the transmission resources of the second downlink transmission signal and / or the transmission resources of the second uplink transmission signal based on the third configuration information in the sixth signal and the fourth configuration information in the seventh signal, thereby enabling the network device to send the second downlink transmission signal on the transmission resources of the second downlink transmission signal and / or receive the second downlink transmission signal on the transmission resources of the second uplink transmission signal.

[0290] It should be noted that the process by which the terminal device determines the transmission resources of the second downlink transmission signal and / or the second uplink transmission signal based on the sixth signal including the third configuration information and the seventh signal including the fourth configuration information, and the process of determining the transmission resources of the second downlink transmission signal and / or the second uplink transmission signal, has been described in detail on the terminal side and will not be repeated here.

[0291] In some embodiments, the method further includes sending an eighth signal, the eighth signal being used to indicate the second time interval.

[0292] In this embodiment, the network device can send an eighth signal to enable the terminal device to obtain a second time interval for comparing the time interval between the fourth configuration information and the transmission resources indicated by the third configuration information, that is, the second time interval is pre-configured by the network device.

[0293] In some embodiments, the method further includes: transmitting a second downlink transmission signal on available / effective transmission resources of the second downlink transmission signal, and / or receiving a second uplink transmission signal on available / effective transmission resources of the second uplink transmission signal;

[0294] Wherein, the available / effective transmission resources of the second downlink transmission signal and / or the second uplink transmission signal are transmission resources indicated in the fourth configuration information that do not overlap with the transmission resources indicated in the third configuration information; or, the available / effective transmission resources of the second downlink transmission signal and / or the second uplink transmission signal are transmission resources indicated in the fourth configuration information whose time interval with the transmission resources indicated in the third configuration information is greater than and / or equal to the second time interval.

[0295] In this embodiment, after the terminal device determines the available / effective transmission resources of the second downlink transmission signal and / or the second uplink transmission signal, the network device can send the second downlink transmission signal based on the available / effective transmission resources of the second downlink transmission signal, and / or receive the second uplink transmission signal on the available / effective transmission resources of the second uplink transmission signal.

[0296] It should be noted that the available / effective transmission resources for the network device to send the second downlink transmission signal and / or receive the second uplink transmission signal may be transmission resources that do not overlap with the transmission resources indicated by the fourth configuration information sent by the network device; or, they may be transmission resources that are indicated by the fourth configuration information sent by the network device, and whose time interval with the transmission resources indicated by the third configuration information sent is greater than and / or equal to the second time interval.

[0297] It is understood that among the transmission resources indicated in the fourth configuration information, transmission resources that overlap with the transmission resources indicated in the third configuration information, or transmission resources among the transmission resources indicated in the fourth configuration information whose time interval with the transmission resources indicated in the third configuration information is less than the second time interval, can all be determined as invalid (i.e., not transmitted or unavailable) transmission resources.

[0298] In other words, among the transmission resources of the 6G first uplink transmission signal and / or the first downlink transmission signal indicated in the fourth configuration information, transmission resources that overlap with the transmission resources of the NR / LTE downlink signal and / or uplink signal indicated in the third configuration information, or transmission resources with a time interval less than the second time interval, cannot enable the reception of the second uplink transmission signal and the transmission of the second downlink transmission signal.

[0299] In this embodiment, by receiving a sixth signal including third configuration information and a seventh signal including fourth configuration information by the terminal device, the second downlink transmission signal and / or the second uplink transmission signal of 6G, as well as the corresponding transmission resources, can be determined. Thus, while realizing spectrum sharing between 6G transmission signals and NR / LTE transmission signals, the resource mapping method of the second downlink transmission signal and / or the second uplink transmission signal is determined.

[0300] Furthermore, compared to traditional NR-LTE resource mapping, the resource mapping method of this invention can determine the 6G downlink and / or uplink transmission signals for the terminal device when multiple transmission resource configurations exist. It also fully considers the antenna architecture under the potential U6G frequency band of 6G, designing different resource matching methods for different signal types, and the resource mapping and / or resource mapping process under different resource matching methods.
