Description

Information transmission methods, electronic devices and storage media Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to an information transmission method, electronic device, and storage medium. Background Technology

[0002] 6G and future mobile communications will offer higher transmission rates, lower latency, greater device connection capacity and density, higher spectrum efficiency, and support for a wider range of services compared to 5G. To better meet the communication needs of vertical industries, 6G and future mobile communications need to support lower latency, such as through Subband Full-Duplex (SBFD) or Full Duplex (FD) technologies, enabling uplink services to be transmitted on downlink time slots or downlink services to be transmitted on uplink time slots. 6G and future mobile communications also need to support more service types, meaning they need to support more access technologies. For example, on the same carrier, in addition to communication via the Uu air interface (the interface between the base station and the UE), they should also support communication via the device direct connection interface (the direct communication interface between UEs, or sidelink interface), as well as communication between relay nodes and UEs, and between base stations and relay nodes.

[0003] In sixth-generation mobile communications (6G) and future mobile technologies, it may be permissible for downlink and uplink communications to be configured on the same symbol, or for downlink and sidelink communications to be configured on the same symbol, within a frequency band, carrier, or bandwidth portion (BWP).

[0004] When downlink and uplink communication are on the same symbol, or when downlink and sidelink communication are on the same symbol, the received signal energy intensity of the UE will change drastically, and the signal reception and processing range of the receiving device will be unpredictable. At present, there is an urgent need to solve the above-mentioned Automatic Gain Control (AGC) problem. Summary of the Invention

[0005] This application provides an information transmission method, electronic device, and storage medium, which aim to enable downlink communication and uplink communication or sidelink communication to be transmitted using the same symbols, reduce the degree of variation in received signal energy intensity, improve the signal reception and processing range of the receiving device, and realize automatic gain control.

[0028] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.

[0029] In the following description, the use of suffixes such as “module,” “part,” or “unit” to denote elements is solely for the purpose of illustration in this application and has no particular meaning in itself. Therefore, “module,” “part,” or “unit” may be used interchangeably.

[0030] Currently, direct communication between User Equipment (UE) and UE is supported, which will be referred to as Sidelink communication below. In the Sidelink communication system, when there is a service to be transmitted between UEs, the service data between UEs can bypass the network side, that is, the service data can be directly sent from the source UE to the target UE through the Sidelink link. Sidelink communication (including Device-to-Device (D2D) and Vehicle-to-Everything (V2X) technologies) can work in various scenarios such as with network coverage, partial network coverage, and no coverage. Sidelink communication can also work on the Intelligent Transportation System (ITS) spectrum, licensed spectrum, and unlicensed spectrum. Sidelink communication and Uu interface communication are shown in Figure 1.

[0031] In 5G mobile communication, Uu interface communication supports two duplexing modes: Time Division Duplexing (TDD) and Frequency Division Duplexing (FDD). In TDD duplexing, radio resources are typically divided into downlink time slots / symbols, uplink time slots / symbols, and flexible slots / symbols, as shown in Figure 2. In FDD duplexing, radio resources are typically divided into downlink carriers and uplink carriers, as shown in Figure 3. In 5G, when sidelink communication operates on licensed spectrum, the sidelink only operates on the uplink carrier or in the uplink time slot; it does not support operation on the downlink carrier, downlink time slot, or flexible slots / symbols.

[0032] Figure 4 is a flowchart of an information transmission method provided in an embodiment of this application.

[0042] In this embodiment, the first symbol may be one or more symbols in a radio resource. The one or more symbols may be configured or specified by the first information. The first symbol may also be a predefined symbol. The number of first symbols in each first resource may be one or more. Each first resource belongs to a first resource set. The first resource set may include multiple first resources. At least one first resource in the first resource set is a downlink resource in a downlink resource set indicated or configured by the first information. That is, at least one first resource in the first resource set may overlap with the downlink resources in the downlink resource set. The symbol adjacent to the first symbol may be used as the second symbol. The second symbol may be the symbol at which the first resource carrying information begins to be mapped.

[0043] In other embodiments, the second symbol includes a first information configuration or designated symbol of the radio resource, or a predefined symbol, wherein the first resource in the first resource set includes at least one second symbol, and the first symbol is the adjacent symbol preceding the second symbol.

[0044] Specifically, the second symbol may include a symbol configured or specified by the first information of the radio resource, or the second symbol may be a predefined symbol.

[0052] Figure 5 is a flowchart of another information transmission method provided in an embodiment of this application. This embodiment is applicable to situations where uplink communication and downlink communication or sidelink communication use the same symbols. This method can be executed by an information transmission device, which can be implemented through software and / or hardware methods and is generally integrated into a base station or terminal equipment. As shown in Figure 5, the method provided in this embodiment specifically includes the following steps:

[0053] Step 210: Send first information about radio resources to the first node, wherein the first information includes at least a set of downlink resources, the first information indicates that at least one downlink resource in the set of downlink resources is the first resource set, the information carried by the first resource in the first resource set is mapped starting from the second symbol, and the information mapped on the first symbol of the first resource includes at least one of the following: information mapped on the second symbol; repetition or duplication of the second symbol; cyclic prefix extension of the second symbol; a sequence for automatic gain control; a signal determined by the second node.

[0054] Specifically, the first information of radio resources can be sent to the first node. This first information can configure or indicate a set of downlink resources. The configured or indicated set of downlink resources includes at least one downlink resource belonging to the first resource set. That is, the first resource of the first resource set can overlap with the downlink resources of the downlink resource set. The information carried by the first resource in the first resource set is mapped starting from the second symbol. The information mapped on the first symbol of the first resource can include at least one of the following: information mapped on the second symbol, repetition or duplication of the second symbol, cyclic prefix extension of the second symbol, sequence for automatic gain control, and signal determined by the second node.

[0055] Based on the above application embodiments, the first information includes configuration information or instruction information.

[0056] In some application embodiments, the downlink resources include at least the radio resources transmitted by the base station to the terminal device, wherein the radio resources include at least one of the following: downlink time slots, time slots containing downlink symbols, downlink symbol groups within a time slot, variable direction time slots for downlink transmission, time slots including variable direction time slot symbols, variable direction symbol groups for downlink transmission within a time slot, full-duplex time slots / symbol groups, sub-band full-duplex time slots, sub-band full-duplex time slot symbol groups, time slots containing sub-band full-duplex symbols, and time slots containing full-duplex symbols.

[0057] In some application embodiments, the first symbol includes a first information configuration or designated symbol of the radio resource, or a predefined symbol, the first resource in the first resource set includes at least one first symbol, and the second symbol is the symbol adjacent to the first symbol.

[0058] In other embodiments, the second symbol includes a first information configuration or designated symbol for the radio resource, or a predefined symbol, wherein the first resource in the first resource set includes at least one second symbol, and the first symbol is the symbol adjacent to the second symbol.

[0059] In some embodiments, the first resource in the first resource set is indicated by the first message, and the first resource is part or all of the downlink resources. It can be indicated by a bitmap, where each downlink resource corresponds to one bit, and the downlink resource with bit 1 is the first resource. Alternatively, it can be indicated by a pattern, such as one pattern representing that the 1st, 3rd, and 5th downlink resources are the first resources.

[0060] Based on the above-described embodiments, the first symbol includes a first information configuration or designated symbol for the wireless resources, or a predefined symbol, including at least one of the following:

[0061] The first symbol of the first resource in the first resource set; the symbol indicating the configuration parameters; the first symbol of the configured control information resource set symbol; the first symbol before the configured control signal resource set symbol; the first symbol of the configured shared channel resource set symbol; the first symbol before the configured shared channel resource set symbol; the first symbol of the configured positioning pilot symbol resource; the first symbol of the configured synchronization signal block resource; the first symbol of the symbol where downlink signals and uplink signals overlap; the first symbol of the symbol where downlink signals and sidelink signals overlap.

[0062] In other embodiments, the first information configuration or designated symbol of the radio resources of the second symbol packet, or a predefined symbol, includes at least one of the following:

[0063] The second symbol of the first resource in the first resource set; the symbol indicating the configuration parameters; the second symbol of the configured control information resource set symbol; the first symbol of the configured control signal resource set symbol; the second symbol of the configured shared channel resource set symbol; the first symbol preceding the configured shared channel resource set symbol; the second symbol of the configured positioning pilot symbol resource; the second symbol of the configured synchronization signal block resource; the second symbol of the symbol where downlink signals and uplink signals overlap; the second symbol of the symbol where downlink signals and sidelink signals overlap.

[0064] In some embodiments, the method further includes: when transmitting a signal, the mapping of the physical signal in the signal starts from a second symbol, the first symbol being a copy of the mapped second symbol, or the content of the mapped second symbol being copied to the first symbol.

[0065] In the embodiments of this application, when transmitting a signal, the mapping of the physical signal starts from the second symbol instead of the first symbol. The first symbol can copy the content of the mapped second symbol to the first symbol, or the first symbol can be a copy of the mapped second symbol.

[0066] In one exemplary implementation, in 6G communication, sidelink (SL) communication can be used in vertical industries and is considered to support Ultra-Reliable Low Latency Communications (URLLC) services, which have high latency requirements. In addition to transmitting or receiving signals on uplink communication resources, SL can also transmit and receive signals on downlink communication or F-slots to reduce the latency of sidelink communication. Therefore, SL communication and DL communication can coexist on the same symbol. The problem of SL signal transmission affecting UE downlink reception is mainly due to the fact that SL signals cause significant interference to downlink signals, or that the power variation of SL signals causes the power variation range of the downlink signal received by the UE to exceed the UE's preset reception range. Currently, interference problems caused by resource conflicts can be solved through resource allocation schemes, but the AGC problem of the power variation range exceeding the UE's preset reception range can be solved by the method provided in the embodiments of this application. Referring to Figure 6, there are two types of communication on a carrier or bandwidth part (BWP): Uu interface communication and SL communication. The resources configured on the network side include DL resources and SL resources. The DL signal can represent the signal transmitted on the Uu interface downlink resource, and the SL signal represents the signal transmitted on the SL communication resource. The DL resources and SL resources overlap in the time domain.

[0067] On a carrier or BWP, when a UE receives a DL signal, the SL signal transmitted by other UEs may affect the UE's DL signal reception. Therefore, on the DL resource, the first symbol of the overlapping part of the DL resource and the SL resource is configured as the first symbol, and the adjacent symbol after the first symbol is the second symbol. The information carried by the DL resource is mapped starting from the second symbol. The information mapped by the first symbol may include at least one of the following: information mapped on the second symbol, repetition or duplication of the second symbol, cyclic prefix extension of the second symbol, sequence for automatic gain control, signal for implementing the decision, etc. The information on the second symbol includes at least one of the following: Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), Physical Broadcast Channel (PBCH), Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), Positioning Reference Signal (PRS), Demodulation Reference Signal (DRMS), Channel State Information Reference Signal (CSI-RS), and Phase-Tracking Reference Signal (PTRS).

[0068] Furthermore, in the embodiments of this application, when UL and SL have the same symbol, corresponding operations can also be performed on UL resources to reduce the impact of SL on UL received signals.

[0069] In other exemplary embodiments, to support URLLC services and further reduce latency, UL signals can be transmitted and received on DL or F time slots, or DL ​​signals can be transmitted and received on UL or F time slots. If DL communication and UL communication are configured or instructed to coexist on the same symbol, there is a problem that the transmission of UL signals affects the UE's downlink reception. For example, the UL signal may cause significant interference to the downlink signal, or the power variation of the UL signal may cause the UE's downlink signal power range to exceed the UE's preset reception range. The interference problem caused by resource conflicts described above can be solved through resource allocation schemes, while the embodiments of this application can solve the AGC problem where the power variation range exceeds the UE's preset reception range.

[0070] Referring to Figure 7, there are two communication directions on a single carrier / BWP: DL communication and UL communication. The network side is configured with DL and UL resources. DL signals represent signals transmitted on the Uu interface downlink resources, and UL signals represent signals transmitted on the Uu interface uplink resources. DL and UL resources overlap in the time domain. On a single carrier / BWP, when a UE receives a DL signal, other UEs transmitting UL signals may affect the UE's DL signal reception. Therefore, on the DL resources, the first symbol overlapping the DL and UL resources is configured as the first symbol, and the adjacent symbol after the first symbol is designated as the second symbol. The information carried by the DL resources is mapped starting from the second symbol. The information mapped by the first symbol may include at least one of the following: information mapped on the second symbol, repetition or duplication of the second symbol, cyclic prefix extension of the second symbol, sequences used for automatic gain control, signals used for decision-making, etc. The information on the second symbol includes at least one of the following: PDCCH, PDSCH, PBCH, PSS, SSS, PRS, DRMS, CSI-RS, PTRS.

[0071] In the embodiments of this application, the scheme can be applied to the configuration of uplink communication resources. UL can replace DL, and DL can replace UL. That is, the corresponding operation is performed on UL resources, which can reduce the impact of DL on UL received signals.

[0072] In some application embodiments, when DL and SL coexist on the same symbol, or when DL and UL coexist on the same symbol in a Seamless Bidirectional Forwarding Detection (SBFD) scenario, the network side (or base station side) sends a configuration or indication of radio resources to the UE. This configuration or indication includes a downlink resource set, such as a DL slot, indicating that at least one downlink resource in the downlink resource set is a first resource set. The information carried by each resource in the first resource set is mapped starting from the second symbol. The first symbol is the symbol adjacent to the second symbol. The information mapped on the first symbol includes at least one of the following: information mapped on the second symbol, repetition or duplication of the second symbol, cyclic prefix extension of the second symbol, sequence for automatic gain control, signal determined by implementation, etc. As shown in Figure 8, the downlink resource set is a TDD frame structure in which the network side or the base station side sends configuration or indication of radio resources to the UE. The TDD frame structure includes a set of downlink resources, which may include at least one of the following: downlink time slot (DL slot), downlink symbol set (DL symbol set) within a time slot, flexible slot that can be used for downlink transmission, flexible symbol set (Flexible symbol set) that can be used for downlink transmission within a time slot, full-duplex time slot / symbol set, and subband full-duplex time slot / symbol set.

[0073] Specifically, the first resource set is a subset of the downlink resources mentioned above, such as a portion of the DL time slots specified in the DL time slots. This can be indicated by a Bitmap or by a first resource set pattern. For example, if the bitmap length is L, within a TDD configuration period, starting from the first DL time slot, the bitmap is mapped sequentially. A DL slot with bit 1 is a resource in the first resource set, and so on for other corresponding TDD configuration periods. Alternatively, if the first resource set pattern is 1, it means that within a TDD period, starting from the first DL slot, the nth slot out of every N DL slots is a resource in the first resource set, where N and n are integers, such as N=4 and n=1.

[0074] The first symbol is a symbol specified in the radio resource configuration or indication, or a predefined symbol. The first symbol can be a resource in the first resource set, such as the second DL slot in Figure 8. This resource includes at least one first symbol, and the second symbol is the symbol adjacent to the first symbol.

[0075] Alternatively, the second symbol may be a symbol specified in a radio resource configuration or indication, or a predefined symbol. The second symbol may be a resource in a first resource set that includes at least one second symbol, and the first symbol may be the symbol adjacent to the second symbol.

[0076] Specifically, the designated symbol for a first symbol on a resource in a first set of resources configured or indicated by radio resources includes at least one of the following:

[0077] 1. Predefine the first symbol of the downlink resource as the first symbol. Or predefine the first symbol of the first resource in the first resource set as the first symbol.

[0078] 2. The symbol indicated by the configuration parameter, such as the nth symbol, or the n1, n2, n3th symbol; n, n1, n2, n3 are integers.

[0079] 3. The first symbol of the configured CORESET (control signal resource set) resource; such as the first symbol configured for PDCCH detection within a DL slot.

[0080] 4. The symbol preceding the configured CORESET (Control Signal Resource Set) symbol; such as the symbol preceding the first configured symbol for PDCCH detection within a DL slot.

[0081] 5. The first symbol of the configured positioning pilot symbol resource; for example, if the positioning pilot symbols are symbols 10, 11, 12, 13 in a slot (starting from 0), then symbol 10 is the first symbol.

[0082] 6. The first symbol of the configured SSB (Synchronization Signal Block) resource;

[0083] 7. The first symbol in the overlapping sequence of downlink and uplink signals;

[0084] 8. The first symbol in the overlapping symbol of the downlink signal and the sidelink signal.

[0085] Referring to Figure 9, the first symbol is a designated symbol on a resource (DL slot) in the first resource set (DL slots) for the configuration or indication of radio resources, that is, the first symbol of the predefined DL slot is the first symbol.

[0086] Specifically, the designated symbol of the second symbol on a resource in a first set of resources configured or indicated by the radio resources includes at least one of the following:

[0087] 1. Predefine the second symbol of the downlink resource as the second symbol. Or predefine the second symbol of the first resource in the first resource set as the second symbol.

[0088] 2. The symbol indicated by the configuration parameter, such as the nth symbol, or the n1, n2, n3th symbol; n, n1, n2, n3 are integers.

[0089] 3. The second symbol of the configured CORESET (control signal resource set) resource; such as the second symbol configured for PDCCH detection within a DL slot.

[0090] 4. The first symbol configured in the CORESET (Control Signal Resource Set); for example, the first symbol configured for PDCCH detection within a DL slot.

[0091] 5. The second symbol of the configured positioning pilot symbol resource; for example, if the positioning pilot symbols are symbols 10, 11, 12, 13 in a slot (starting from 0), then symbol 11 is the second symbol.

[0092] 6. The second symbol of the configured SSB (Synchronization Signal Block) resource;

[0093] 7. The second symbol in the overlapping symbols of the downlink and uplink signals;

[0094] 8. The second symbol in the overlapping symbol of the downlink signal and the sidelink signal.

[0095] Referring to Figure 9, the second symbol is a designated symbol on a resource (DL slot) within the first resource set (DL slots) for the configuration or indication of radio resources; that is, the second symbol of a predefined DL slot is the second symbol. The first symbol preceding the second symbol is the first symbol.

[0096] Furthermore, when the base station transmits signals, the mapping of physical signals begins from the adjacent symbol after the first symbol, that is, from the second symbol. The first symbol can be a copy of the mapped second symbol, or the content of the mapped second symbol can be copied onto the first symbol.

[0097] In some other exemplary implementations, in 6G systems, in certain scenarios, such as when DL and SL coexist on the same symbol, or when DL and UL coexist on the same symbol in SBFD scenarios, the UE receives radio resource parameters (such as TDD frame structure) configured or indicated by the network side (base station side), including downlink resource sets (such as DL slots), indicating that at least one downlink resource in the downlink resource set is a first resource set, the information carried by each resource in the first resource set is mapped starting from the second symbol, and the information mapped on the first symbol includes at least one of the following: information mapped on the second symbol, repetition or duplication of the second symbol, cyclic prefix extension of the second symbol, sequence for automatic gain control, and signals determined by implementation.

[0098] Referring to Figure 10, the downlink resource set is the set of downlink resources in the TDD frame structure in which the network side (base station side) sends the configuration or indication of radio resources to the UE. The downlink resources may include at least one of the following: downlink time slot (DL slot), time slot containing DL symbol, downlink symbol set within a time slot, flexible slot that can be used for downlink transmission, time slot containing flexible symbol, flexible symbol set within a time slot that can be used for downlink transmission, full-duplex time slot / symbol set (FD slot / symbol set), sub-band full-duplex time slot (SBFD slot), sub-band full-duplex time slot symbol set (SBFD symbol set), time slot containing SBFD symbol, and time slot containing FD symbol.

[0099] The first resource set refers to a portion of the downlink resources mentioned above, such as a time slot containing a DL symbol in Figure 10. Alternatively, the downlink resources can be DL slots, or a combination of DL slots and time slots containing DL symbols. The first resource is a portion of the downlink resources mentioned above, such as the indicated slots. It can be indicated by a bitmap or by a first resource set pattern. For example, if the bitmap length is L, within a TDD configuration period, starting from the first downlink resource, the bitmap is mapped sequentially, where the downlink resource corresponding to a bit of 1 is a resource in the first resource set. Other corresponding TDD configuration periods follow the same pattern. Alternatively, if the first resource set pattern is 1, it means that within a TDD period, starting from the first downlink resource, the nth slot out of every N downlink resources is a resource in the first resource set, where N and n are integers, such as N=4 and n=1.

[0100] In some application embodiments, the first symbol is a symbol specified in the configuration or indication of the radio resource, or a predefined symbol. In a resource within the first resource set, such as the second DL slot in Figure 10 above, the resource includes at least one first symbol; the second symbol is the symbol adjacent to the first symbol.

[0102] Specifically, the designated symbol on a resource in the first set of resources for configuring or indicating wireless resources includes at least one of the following:

[0105] 3. The first symbol of the configured CORESET (control signal resource set) resource; such as the first symbol configured for PDCCH detection within a DL slot.

[0106] 4. The symbol preceding the configured CORESET (Control Signal Resource Set) symbol; such as the symbol preceding the first configured symbol for PDCCH detection within a DL slot.

[0107] 5. The first symbol of the configured positioning pilot symbol resource; for example, if the positioning pilot symbols are symbols 10, 11, 12, 13 in a slot (starting from 0), then symbol 10 is the first symbol.

[0108] 6. The first symbol of the configured SSB (Synchronization Signal Block) resource;

[0109] 7. The first symbol in the overlapping sequence of downlink and uplink signals;

[0114] 3. The second symbol of the configured CORESET (control signal resource set) resource; such as the second symbol configured for PDCCH detection within a DL slot.

[0115] 4. The first symbol configured in the CORESET (Control Signal Resource Set); for example, the first symbol configured for PDCCH detection within a DL slot.

[0116] 5. The second symbol of the configured positioning pilot symbol resource; for example, if the positioning pilot symbols are symbols 10, 11, 12, 13 in a slot (starting from 0), then symbol 11 is the second symbol.

[0117] 6. The second symbol of the configured SSB (Synchronization Signal Block) resource;

[0118] 7. The second symbol in the overlapping symbols of the downlink and uplink signals;

[0119] 8. The second symbol in the overlapping symbol of the downlink signal and the sidelink signal.

[0120] Referring to Figure 11, the first symbol is a designated symbol on a resource in the first resource set (downlink resource slot) of the radio resource configuration or indication, that is, the symbol before the configured CORESET (control signal resource set) symbol; as shown in Figure 11, within the DL slot, the symbol before the first configured symbol for PDCCH detection is the first symbol.

[0121] Alternatively, referring to Figure 11, the second symbol is a designated symbol on a resource in the first resource set (downlink resource slot) of the radio resource configuration or indication, that is, the first symbol of the configured CORESET (control signal resource set); as shown in Figure 11, within the DL slot, the first symbol configured for PDCCH detection is the second symbol.
