Abstract
Description
Technical Field
[0001] This application relates to the field of communication technology, specifically to an information indication method, apparatus, device, and storage medium. Background Technology

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.
[0030] The steps illustrated in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in a different order than that presented here.
[0031] The technical solutions of this application can be applied to various communication systems, such as: Global System for Mobile Communication (GSM) systems, Code Division Multiple Access (CDMA) systems, Wideband Code Division Multiple Access (WCDMA) systems, General Packet Radio Service (GPRS), Long Term Evolution (LTE) systems, LIE-A (Advanced Long Term Evolution) systems, Universal Mobile Telecommunication System (UMTS), and 5G systems, etc. The embodiments in this application are not limited to these systems. This application uses a 5G system as an example for illustration.
[0032] In vehicle-to-everything (V2X) technology, there are applications including partial coverage scenarios, where adjacent UEs include UEs within the coverage area and UEs outside the coverage area, such as... Figure 1As shown, the UE within the coverage area is within the coverage area of the base station, while the UE outside the coverage area is outside the coverage area of the base station. Sidelink communication is performed between the UE within the coverage area and the UE outside the coverage area. The UE within the coverage area and the UE outside the coverage area can operate on different carriers, for example, the UE within the coverage area can operate on a shared carrier while the UE outside the coverage area can operate on a dedicated carrier, or they can operate on the same carrier, for example, both can operate on a shared carrier.
[0033] When an in-coverage UE and an out-of-coverage UE operate on the same carrier, they need to maintain a consistent frame structure on that carrier to correctly receive V2X messages and achieve V2X communication. When both in-coverage and out-of-coverage UEs operate on a shared carrier, in order not to affect communication of the cellular communication system on the Uu link, the out-of-coverage UE must maintain the same frame structure as the in-coverage UE to achieve V2X communication with the in-coverage UE.
[0034] First, it should be noted that in this embodiment, the base station can be a device capable of communicating with a user terminal. The base station can be any device with wireless transceiver capabilities, including but not limited to: NodeB, eNodeB, base stations in 5G communication systems, base stations in future communication systems, access nodes in WiFi systems, wireless relay nodes, and wireless backhaul nodes. The base station can also be a wireless controller in a cloud radioaccess network (CRAN) scenario; it can also be a small cell, a transmission reference point (TRP), etc., and this embodiment is not limited to these.
[0035] In this application embodiment, the user terminal is a device with wireless transceiver capabilities that can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on water (such as ships); and it can also be deployed in the air (e.g., on airplanes, balloons, and satellites). The user terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal, augmented reality (AR) terminal, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc. The embodiments of this application do not limit the application scenario. The user terminal may also be referred to as a terminal, access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication device, UE agent, or UE device, etc. The embodiments described in this application are not limited.
[0036] In Long Term Evolution (LTE) V2X, Time Division Duplex Uplink and Downlink (TDDUL-DL) configuration information is contained in the Physical Sidelink Broadcast Channel (PSBCH), which is used to indicate the TDD system uplink and downlink frame structure configured on the shared carrier. A total of 7 types of TDD UL-DL configuration information are supported in the LTE system, and the configuration value within the coverage area can be indicated by 3 bits in the PSBCH.
[0037] In NR systems, frame structure configuration includes semi-static Cell-specific frame structure configuration (tdd-UL-DL-Configuration Common), semi-static UE-specific frame structure configuration (tdd-UL-DL-ConfigurationDedicated), and dynamic Group-common frame structure configuration (DCI format 2_0). In NR V2X, the PSBCH only indicates semi-static Cell-specific frame structure configuration information, i.e., the content of tdd-UL-DL-ConfigurationCommon. The configuration of tdd-UL-DL-ConfigurationCommon supports a single DL-UL pattern configuration (pattern1) and dual DL-UL pattern configurations (pattern1 and pattern2). A configured DL-UL pattern can contain one, two, or three of the following: DL slots, Unknown slots, and UL slots. If more than one type of slot is included, the configuration strictly follows the order of DL, Unknown, and UL. The first slot of an Unknown slot can contain a DL symbol, and the last slot can contain a UL symbol, as shown in the appendix. Figure 2 As shown.
[0038] In the prior art, the PSBCH indicates the tdd-UL-DL-Configuration Common configuration information of NR, including whether it is a single DL-UL pattern configuration or a dual DL-UL pattern configuration, and the cycle value corresponding to the single-cycle configuration or dual-cycle configuration (determined according to Table 1 and Table 2 respectively), as well as the number of UL slots that can be used for edge link resource mapping contained in the tdd-UL-DL-Configuration Common configuration.

[0043]
[0044] When NR V2X operates in the LTE Uu band, existing technologies cannot provide S-SSB and / or PSBCH with indication of TDDUL-DL configuration information in LTE, and existing solutions need to be enhanced.
[0045] In one embodiment, this application provides an information indication method, the method being applied to a first node, such as... Figure 3 The information indication method provided in this embodiment mainly includes steps S11 and S12.
[0046] S11. Receive configuration information.
[0047] S12. Transmit a first channel based on the first radio access technology (RAT), wherein the first channel carries indication information provided by the configuration information, and the indication information indicates the radio frame structure information of the second RAT.
[0048] In this implementation, the first node is any one of the aforementioned UEs within the coverage area. Configuration information refers to the TDD-UL-DL common configuration information sent by the base station to the UEs within the coverage area.
[0049] Sending the first channel based on the first RAT can be understood as the UE inside the coverage sending the first channel to the UE outside the coverage based on the first RAT, so that the UE outside the coverage receives the indication information carried in the first channel. The UE outside the coverage determines the TDD frame structure based on the radio frame structure information of the second RAT according to the indication information, and then determines the TDD frame structure based on the TDD frame structure information. This ensures that the frame structure is consistent when the UE inside the coverage and the UE outside the coverage are working in the LTE Uu band, thereby determining the accurate location of the SL resource pool of the UE outside the coverage relative to the UE inside the coverage, and realizing V2X communication between the UE outside the coverage and the UE inside the coverage.

For example, 4 bits of the 7 bits in the PSBCH indicating the number of UL slots available for sidelink resource mapping contained in the tdd-UL-DL-ConfigurationCommon configuration are used. For instance, a8a9a... 10 a 11 The value of the Special subframe configuration in LTE is indicated, and its range is 0 to 10.
[0132] A concrete example is the bit string a8 a9 a. 10 a 11 0000 indicates the configuration with index 0 in Special subframe configuration in LTE, which is the configuration information with a value of 0 in Special subframe configuration in Table 4, bit string a8 a9 a 10 a 11 0001 indicates the configuration with index 1 in the Special subframe configuration in LTE, which is the configuration information with a value of 1 in Special subframe configuration in Table 4, and so on, bit string a8 a9a 10 a 11 1010 indicates the configuration with index 10 in the Special subframe configuration in LTE, which is the configuration information with a value of 10 in the Special subframe configuration in Table 4.
[0133] In one embodiment, in the PSBCH, the TDD frame structure information of LTE is indicated by a first indication information combined with a second indication information. The TDD frame structure information includes one or more of the following: TDD uplink / downlink configuration information, special subframe configuration information, subcarrier spacing (SCS), radio frame structure type, radio frame structure configuration period, and uplink / downlink handover period in the radio frame structure.
[0134] For example, the first indication information is the content of one bit a0 in PSBCH used to indicate the single or double cycle configuration in tdd-UL-DL-ConfigurationCommon, for example, the indication value of a0 is 0.
[0135] The second indication information includes: first frame structure indication information and / or second frame structure indication information.
[0136] For example, the first frame structure indication information is carried in the PSBCH in 4 bits a1 a2 a3 a4 indicating the DL-UL pattern configuration period value. The values of a1 a2 a3 a4 indicate the LTE uplink and downlink configuration information.
[0137] For example, bit string a1 a2 a3 a4 = 1001 indicates the configuration information with uplink-downlink configuration index 0 in LTE, which is the configuration information with uplink-downlink configuration value of 0 in Table 3; bit string a1 a2 a3a4 = 1010 indicates the configuration information with uplink-downlink configuration index 1 in LTE, which is the configuration information with uplink-downlink configuration value of 1 in Table 3; and so on, bit string a1a2a3a4 = 1111 indicates the configuration information with uplink-downlink configuration index 6 in LTE, which is the configuration information with uplink-downlink configuration value of 6 in Table 3.
[0138] For example, the second frame structure indication information is carried in the PSBCH in 7 bits or a portion of 7 bits (e.g., 4 bits) indicating the number of UL slots available for sidelink resource mapping in the tdd-UL-DL-ConfigurationCommon configuration. This indicates the Special subframe configuration information defined by LTE. For instance, bit string a5 a6 a7a8 = 0000 indicates the configuration with Special subframe configuration index 0 in LTE, i.e., the configuration information with Special subframe configuration value 0 in Table 4; bit string a5 a6 a7a8 = 0001 indicates the configuration with Special subframe configuration index 1 in LTE, i.e., the configuration information with Special subframe configuration value 1 in Table 4; and so on, bit string a5 a6 a7a8 = 1010 indicates the configuration with Special subframe configuration index 10 in LTE, i.e., the configuration information with Special subframe configuration value 10 in Table 4.
[0139] In one embodiment, the PSBCH uses 7 bits indicating the number of UL slots available for sidelink resource mapping included in the tdd-UL-DL-ConfigurationCommon configuration to indicate the uplink and downlink configuration information defined by LTE. Specifically, the bit string a5 a6 a7 a8 a9 a 10 a 11These indicate the values in columns 2, 3, 4, 6, 7, 8, and 9 of the Subframe number in Table 3, using bits 0 or 1 to correspond to one of D, S, and U. For example, a5 a6 a7 a8 a9 a 10 a 11 =1100110 indicates the configuration information in Table 3 where the Uplink-downlink configuration value is 1. Here, it is agreed that bit 1 represents U and bit 0 represents D or S.
[0140] Another implementation example is that the values in columns 0, 1, 4, and 5 of the Subframe number in Table 3 are the same for different uplink-downlink configurations, and can be determined as fixed values.
[0141] In one embodiment, the PSBCH indicates LTE uplink-downlink configuration information. For example, the Subframe number information in Table 3 is indicated using the two-cycle indication method in the existing PSBCH indication mechanism.
[0142] For example, the configuration information with an Uplink-downlink configuration value of 3 in Table 3 is indicated in a dual-cycle manner, with both dual-cycle p1 and p2 being 5ms. In the PSBCH, the bit a0 indicating the single / dual-cycle configuration in tdd-UL-DL-ConfigurationCommon has a value of 1, and the bit string a1a2a3a4 indicating the DL-UL pattern configuration cycle value has a value of 1110. The corresponding dual-cycle uplink and downlink configurations for pattern1 and pattern2 are DSUUU and DDDDD, respectively. The bit string a5a6a7a8a9a in the PSBCH, indicating the number of UL slots available for sidelink resource mapping in the tdd-UL-DL-ConfigurationCommon configuration, is used to indicate this. 10 a 11 The indication granularity w is determined according to Table 2. Assuming SL SCS is 15kHz, then w is 1. Based on the formula, the number of UL time slots to be indicated is 3, i.e., bit string a5a6a7a8a9a. 10 a 11 The indicated value is 3.
[0143] In one embodiment, the PSBCH indicates the subcarrier spacing (SCS) used for wireless communication, and / or the radio frame structure type, and / or the radio frame structure configuration period or uplink / downlink handover period in the radio frame structure, and / or the radio frame structure configuration, and / or the ad hoc subframe or time slot configuration, through an indication field. For example, the above is indicated by bit a0 indicating single / double period configuration in tdd-UL-DL-ConfigurationCommon and 4 bits a1a2a3a4 indicating the DL-UL pattern configuration period value.
[0144] For example, bit a0 indicates a value of 0, bit string a1a2a3a4 = 1100 indicates that the SCS of the LTE wireless communication system is 15kHz, the wireless frame structure configuration period is 10ms, and / or the frame structure uplink-downlink switching period is 10ms or 5ms. And / or at least one of the following wireless frame structure configuration information: 7 configurations of LTE frame structure type 2, LTE frame structure type 1 configuration, LTE frame structure type 3 configuration. For example, the configuration information where the uplink-downlink configuration value is 3 in LTE frame structure type 2.
[0145] In one embodiment, in the PSBCH, the 1-bit indication information in the reserved bits indicates that the PSBCH indication field contains an indication of LTE frame structure configuration information. For example, the bit string a0~a00 in the PSBCH used to indicate TDD uplink / downlink configuration information 11 Includes instructions on LTE frame structure configuration information.
[0146] For example, a bit value of 1 in the reserved bits of the PSBCH indicates that the current PSBCH contains an indication of LTE frame structure configuration information. For instance, bit string a1 a2 a3 indicates LTE uplink-downlink configuration information; for example, a1 a2 a3 = 000 indicates the configuration information with uplink-downlink configuration index 0 in LTE, which is the configuration information with an uplink-downlink configuration value of 0 in Table 3. As another example, bit string a5a6a7a8 indicates LTE special subframe configuration information; for example, a5a6a7a8 = 0001 indicates the configuration with special subframe configuration index 1 in LTE, which is the configuration information with a special subframe configuration value of 1 in Table 4.
[0147] In one embodiment, in the PSBCH, 12 bits a0 to a0 are configured using the instruction tdd-UL-DL-ConfigurationCommon. 11 The information may contain part or all of the frequency division duplex (FDD) frame structure.
[0148] For example, the 12 bits a0 to a0 in the PSBCH indicating the configuration of tdd-UL-DL-ConfigurationCommon. 11 All zeros or all one bits, or 7 bits a5 to a5. 11 All zeros or all 1s indicate that the radio frame structure of NR or LTE is of type FDD.
[0149] For example, in the PSBCH, the bit a0 used to indicate the single or double cycle configuration in the tdd-UL-DL-ConfigurationCommon configuration has an indication value of 0, and the 4 bits a1a2a3a4 used to indicate the DL-UL pattern configuration cycle value in the tdd-UL-DL-ConfigurationCommon configuration have any one of the values 1001, 1010, 1011, 1100, 1101, 1111, indicating that the radio frame structure of NR or LTE is of type FDD.
[0150] For example, the 7 bits a5a6a7a8a9a in the PSBCH used to indicate the number of UL slots available for sidelink resource mapping contained in the tdd-UL-DL-ConfigurationCommon configuration. 10 a 11 Both 1s or both 0s indicate that the radio frame structure of NR or LTE is of type FDD.
[0151] For example, in the PSBCH, bit a0, which indicates the single / double cycle configuration in the tdd-UL-DL-ConfigurationCommon configuration, has an indication value of 0, and bits a5a6a7a8a9a, which indicate the number of UL slots available for sidelink resource mapping in the tdd-UL-DL-ConfigurationCommon configuration, are used to indicate the number of UL slots available for sidelink resource mapping. 10 a 11 If both are 0, it indicates that the radio frame structure of NR or LTE is of type FDD.
[0152] For example, the period of the tdd-UL-DL-ConfigurationCommon configuration indicated in the PSBCH is either a UL subframe or a UL slot; or, the period of the tdd-UL-DL-ConfigurationCommon configuration indicated in the PSBCH is either a UL subframe or a UL slot.
[0153] In one embodiment, reserved bits in the PSBCH are used to indicate the frequency division duplex (FDD) frame structure.
[0154] For example, using one bit in the reserved bits of the PSBCH with a value of 1 or 0 indicates that the radio frame structure of NR or LTE is of type FDD. For example, using two bits in the reserved bits of the PSBCH with a value of any one of 00, 01, 10, or 11 indicates that the radio frame structure of NR or LTE is of type FDD.
