Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method and related equipment for reporting physical random access channels. Background Technology

[0002] The 5G system supports the ability to optimize Random Access Channel (RACH) resources by receiving Physical Random Access Channel (PRACH) reports from terminals. Currently, the PRACH report includes the following information:

[0003] 1. Competition detection indication for each RACH attempt;

[0004] 2. The index of the SSB and the number of RACH preambles sent on each attempted SSB are listed in chronological order of attempts;

[0005] 3. Indicates whether the selected SSB is higher or lower than the configured RSRP threshold for each RACH attempt;

[0006] 4. Two-step RACH information.

[0007] Based on the above solutions, in specific scenarios such as low-altitude areas, existing protocols such as 3GPP Rel-18 cannot fully meet the needs of practical applications. For example, in live network testing, there are cases where drones sending PRACH cannot access the network.

[0027] According to another aspect of this disclosure, a communication system is provided, including the user equipment and network-side equipment described above.

[0028] According to another aspect of this disclosure, an electronic device is provided, comprising: a memory for storing instructions; and a processor for calling the instructions stored in the memory to implement the above-described physical random access channel report reporting method.

[0029] According to another aspect of this disclosure, a computer-readable storage medium is provided that stores computer instructions thereon, which, when executed by a processor, implement the above-described physical random access channel report reporting method.

[0030] According to another aspect of this disclosure, a computer program product is provided, which stores instructions that, when executed by a computer, cause the computer to implement the above-described physical random access channel report reporting method.

[0031] According to another aspect of this disclosure, a chip is provided, including at least one processor and an interface;

[0034] The physical random access channel report reporting method and related equipment provided in this disclosure optimize the random access process by sending a random access report containing more information to the network side through the user equipment. Compared with the prior art, the random access report adds key data such as cell information, carrier information, altitude information and preamble format, thereby providing richer information support for solving access problems in specific scenarios.

[0035] Cell identifiers can be used to identify the specific cell in which a user equipment (UE) is attempting random access, aiding in network management and fault location. Cell subcarrier spacing and MSG1 subcarrier spacing provide key parameters about cell configuration, helping to understand the communication details between the UE and the network side. Cells supporting airborne devices and air-to-ground cell indication information, for airborne devices such as UAVs, indicate whether it is a regular ground cell or a cell specifically designed for airborne services, facilitating the differentiation of different access environments. Cell power configuration information provides information about the transmit power settings within the cell, helping to assess whether the signal strength is sufficient to support successful access. Carrier information, including the specific frequency band or carrier frequency used, is crucial for understanding which frequency band the UE is attempting to access on, helping to identify potential spectrum interference issues and optimize resource allocation.

[0036] Altitude information directly reflects the altitude of a user device when it attempts to access the network. This is especially important for aerial devices such as drones, enabling the network to adjust its coverage strategy based on different altitudes and resolve access failures caused by altitude changes.

[0037] The preamble format affects the success rate and performance of random access. Different preamble formats are suitable for different scenarios and distances. By reporting the preamble format, we can better analyze the reasons for access failure, such as whether an unsuitable preamble format was selected for the current environment.

[0038] In summary, this solution significantly improves the network's ability to obtain details about access attempts by enhancing the content of random access reports. This is particularly beneficial in complex environments such as drone operations, as it not only helps to quickly locate and resolve problems but also provides data support for optimizing network resource allocation, thereby improving overall network performance and quality of service.

[0057] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The components of the embodiments of this disclosure described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed disclosure, but merely represents selected embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0058] 5G is the fifth generation of mobile communication technology. Compared to previous generations, 5G supports high speed, low latency, massive connectivity, high reliability, and network slicing. These characteristics make 5G a crucial infrastructure for driving digital transformation and will profoundly impact various fields such as industry, transportation, healthcare, and entertainment. The NG-RAN node in 5G can be one of the following two types:

[0059] 1. gNB: User equipment functions that provide NR (New Radio) user plane and control plane protocols for user equipment (UE);

[0060] 2. ng-eNB: Provides user equipment functions for user equipment (UE) that include E-UTRA (Enhanced Universal Terrestrial Radio Access) user plane and control plane protocols.

[0061] gNB and ng-eNB are interconnected via the Xn interface, such as Figure 1 As shown. Furthermore, the gNB and ng-eNB connect to the 5G core network (5GC) via the NG interface, specifically:

[0062] 1. Connect to AMF (Access and Mobility Management Function) via NG-C interface;

[0063] 2. Connect to UPF (User Plane Functions) via NG-U interface.

[0064] 5G (NR) introduces supplementary uplink and supplementary downlink (SUL / SDL). SUL and SDL are each independent cells, primarily used to carry uplink (downlink) radio links for users at the edge of NR coverage. The supplementary uplink (SUL) supplements the uplink coverage of high-frequency NR cells. Terminals can perform uplink transmissions via either the normal uplink (NUL) or SUL. When the uplink carrier signal deteriorates, the terminal can switch from NUL to SUL.

[0065] The 5G system, in its Release 18 (R18) phase, supports air-to-air (ATO) communication technology and aeronautical communication technology (ATG), enabling NR connectivity for UEs capable of air communication through the following functions. Furthermore, it supports HSDN for high-speed mobile scenarios, supporting mobile applications such as high-speed rail. In 5G NR (New Radio), nr-NS-PmaxList is a parameter defined in the 3GPP technical specification, related to the maximum power level of non-serving carriers. Specifically, nr-NS-PmaxList is a set of parameters describing the nr-NS-PmaxList and additional spectrum emission requirements that a user equipment (UE) can use on a carrier. Each entry in this list corresponds to a frequency band, containing the maximum transmission power limit (P_max) and additional spectrum emission limit for non-serving carriers to meet network requirements for spectrum usage.

[0066] The 5G system supports the ability to use PRACH reports from terminals for RACH resource optimization, including the following information:

[0067] 1. Competition detection indication for each RACH attempt;

[0068] 2. The index of the SSB and the number of RACH preambles sent on each attempted SSB are listed in chronological order of attempts;

[0069] 3. Indicates whether the selected SSB is higher or lower than the configured RSRP threshold for each RACH attempt;

[0070] 4. Two-step RACH information.

[0071] The inventors discovered that during live network testing, there were instances where drones could not connect to PRACH, primarily due to varying coverage and beamforming conditions at different altitudes. Therefore, from a PRACH configuration optimization perspective, optimizations are needed for both aerial and millimeter-wave conditions, and the following issues exist:

[0072] 1. The PRACH report lacks altitude information, making it impossible to deduce at which altitude the problem occurred: Current testing shows that the drone's access capabilities vary at different altitudes, therefore the measurement report cannot reflect at which altitude the access problem occurred;

[0073] 2. Unable to determine whether access is on a SUL carrier and on which SSB: Currently, the reported information only includes the cell identifier and carrier frequency. However, since a physical carrier can support multiple SSBs, and uplink also uses SUL, and the frequency absoluteFrequencyPointA used in the current protocol is a downlink frequency value, it is impossible to deduce whether access is occurring on a PRACH associated with a SUL and a specific SSB.

[0074] 3. Lack of uplink power transmission data: Since the maximum uplink power of airborne user equipment varies in different low-altitude cells and the transmission data of ground cells are also different from those of airborne cells, it is impossible to analyze from the measurement report whether the problem occurs in the drone cell or whether it is caused by configuration.

[0075] 4. Lack of PRACH format information: Different access formats for PRACH have different access capabilities and ranges, but the current failure information does not include information on the incorrect format reporting content.

[0076] Based on the above analysis of requirements and reasons, the current 3GPP Rel-18 protocol cannot support PRACH information reporting in low-altitude scenarios. Therefore, it is necessary to enhance the functionality through new standardization methods to meet the needs of network deployment and optimization.

[0077] The deficiencies of the above solutions and the proposed solutions are the result of the inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure below should be considered as the inventor's contribution to this disclosure.

[0078] The following detailed description of this exemplary implementation method is provided in conjunction with the accompanying drawings and embodiments.

[0079] Figure 2 This diagram illustrates a flowchart of a physical random access channel report reporting method according to an embodiment of the present disclosure, as follows: Figure 2 As shown, the physical random access channel report reporting method provided in this embodiment includes S201-S202.

[0080] In S201, the network side sends a first request message to the user equipment.

[0081] The first request message carries first instruction information, which is used to instruct the user equipment to report random access procedure information or to include highly relevant random access procedure information.

[0082] In S202, the user equipment sends a first response message to the network side.

[0083] The first response message carries at least one random access report, which includes at least one of the following: cell information, carrier information, altitude information, and preamble format. The cell information includes the cell identifier, cell subcarrier spacing, physical random access channel or subcarrier spacing of message 1MSG1, cell supporting aerial UE, air-to-ground cell indication information, and cell power configuration information.

[0084] In some embodiments, the carrier information included in the random access report is the uplink carrier configuration. 5G (NR) introduces Supplementary Uplink (SUL) and Supplementary Downlink (SDL). SUL and SDL are each independent cells, primarily used to carry uplink (downlink) radio links and bearers for users at the edge of NR coverage; Supplementary Uplink (SUL) can supplement the uplink coverage of high-frequency NR cells. Terminals can perform uplink transmissions through either the Normal Uplink (NUL) or SUL. When the uplink carrier signal deteriorates, the terminal can switch from NUL to SUL.

[0085] In some embodiments, the first request message and the first response message may be RRC (Radio Resource Control) messages. In some embodiments, the first request message may be a User Equipment Information Request (UEInformationRequest) in a 5G system or a message for obtaining user information in a 6G system.

[0086] In some embodiments, the random access report is determined based on the random access information of the user equipment; the random access information includes at least one first piece of information; the first piece of information includes at least one public terrestrial mobile network or independent non-public network, and at least one of cell information, carrier information, altitude information, and preamble format.

[0087] The Physical Random Access Channel Reporting Method of this disclosure allows the terminal side (user equipment) to assist the network side in optimizing related access performance by reporting its own altitude, uplink carrier configuration, attempted access cell type, PRACH format, and other information, thereby providing reasonable assistance for the subsequent mobility and resource allocation of specific user equipment.

[0088] Figure 3 This diagram illustrates a flowchart of a physical random access channel report reporting method according to an embodiment of the present disclosure, as follows: Figure 3 As shown, the physical random access channel report reporting method provided in this embodiment includes S301-S303.

[0089] In S301, the user equipment determines the random access information.

[0090] The random access information includes at least one first piece of information; the first piece of information includes at least one Public Land Mobile Network (PLMN) or Stand-alone Non-Public Network (SNPN), and at least one of cell information, carrier information, altitude information, and preamble format; the cell information includes cell identifier, cell subcarrier spacing, subcarrier spacing of physical random access channel or message 1MSG1, cell supporting air-to-ground equipment, air-to-ground (ATG) cell indication information, and cell power configuration information.

[0091] In S302, the network side sends a first request message to the user equipment.

[0092] The first request message carries first instruction information, which is used to instruct the user equipment to report random access procedure information or to include highly relevant random access procedure information.

[0093] In S303, the user equipment sends a first response message to the network side.

[0094] The first response message carries at least one random access report, which includes at least one of the following: cell information, carrier information, altitude information, and preamble format.

[0095] In some embodiments, the carrier information is an uplink carrier configuration.

[0096] In some embodiments, determining random access information in S301 above may be done under a preset scenario; wherein the preset scenario includes: when a random access process initialized with a 4-step or 2-step random access type is successfully executed, or when the on-demand system information acquisition process fails or succeeds in the RRC idle state or RRC inactive state, or when the RA-SDT (Random Access Small Data Transmission) operation fails or succeeds.

[0097] In some embodiments, the random access report is determined based on random access information.

[0098] In some embodiments, S301 above may involve determining and saving random access information. That is, the above method may also include the user equipment saving the random access information; and discarding the random access information after a first duration following the last successful random access procedure, or after a first duration following a failed or successful completion of the on-demand system information acquisition procedure.

[0099] In some embodiments, after determining the random access information in S301, a first access report can be generated based on the random access information; and a second access report can be determined based on the first access report; wherein the random access report is either the first access report or the second access report.

[0100] In some embodiments, after the user equipment confirms the successful transmission of the first response message at the underlying layer, it discards the random access information. The underlying layer includes at least one of the Media Access Control (MAC) layer, Radio Link Control (RLC) layer, and Packet Data Convergence Protocol (PDCP) layer.

[0101] This disclosure embodiment can obtain the flight altitude of the terminal when performing random access in the event of random access failure or success, thereby supporting performance optimization for UAVs; this disclosure embodiment supports optimization of whether the terminal access carrier is SUL and PRACH format acquisition, thereby supporting network optimization of random access configuration for the corresponding cell.

[0102] Figure 4 This diagram illustrates a flowchart of a physical random access channel report reporting method according to an embodiment of the present disclosure, as follows: Figure 4As shown, the physical random access channel report reporting method provided in this embodiment includes S401-S404.

[0103] In S401, the user equipment determines the random access information.

[0104] In S402, the user equipment reports its capabilities to the network side, including support for highly relevant machine access process information.

[0105] In S403, the network side sends a first request message to the user equipment.

[0106] In S404, the user equipment sends a first response message to the network side.

[0107] In some embodiments, the random access report is used by the network side to adjust the uplink parameter configuration. Adjusting the uplink parameter configuration includes adjusting at least one of the following: the uplink supplementary link (SUL) threshold value, the uplink random access format, the beam direction of the synchronization signal block (SSB), and the uplink power configuration of the terminal. The beam direction of the synchronization signal block includes the synchronization signal block beam pointing to the air or to the ground, or the electronic tilt angle of the synchronization signal block beam.

[0108] Figure 5 This diagram illustrates a flowchart of a physical random access channel report reporting method according to an embodiment of the present disclosure, as follows: Figure 5 As shown, the physical random access channel report reporting method provided in this embodiment includes S501-S505, wherein S501-S504 are the same as S401-S404 in the above embodiment, and will not be described again here.

[0109] In S505, the uplink parameter configuration is adjusted according to at least one random access report. The adjustment of the uplink parameter configuration includes adjusting at least one of the following: the uplink supplementary link threshold value, the uplink random access format, the beam direction of the synchronization block, and the uplink power configuration of the terminal. The beam direction of the synchronization block includes the synchronization block beam pointing to the air or to the ground, or the electronic tilt angle of the synchronization block beam.

[0110] In some embodiments, the network side includes at least one wireless node and a core network node; wherein, at least one wireless node is a master node, and if there are other wireless nodes, the remaining wireless nodes other than the master node are auxiliary nodes; the master node and auxiliary nodes use the same or different wireless standards, and the wireless standards are 4G, 5G or 6G.

[0111] Figure 6 This diagram illustrates a flowchart of a physical random access channel report reporting method according to an embodiment of the present disclosure, as follows: Figure 6 As shown, the master node receives the first response message on the network side. This embodiment is similar to the one described above. Figures 2-5The implementation methods are the same and will not be repeated here.

[0112] Figure 7 This diagram illustrates a flowchart of a physical random access channel report reporting method according to an embodiment of the present disclosure, as follows: Figure 7 As shown, the secondary node receives the first response message on the network side. When the secondary node receives the first response message, it sends the second information to the primary node through the interface with the primary node. The second information includes at least one target random access report.

[0113] In some embodiments, the second information also includes wireless standard information.

[0114] The embodiments disclosed herein do not involve any impact on user equipment, because the network-side solution has good forward compatibility and is easy to deploy and implement in the network.

[0115] In some embodiments, the network side described above can be a base station. A base station (gNB) can be divided into different functional units. For example... Figure 8 As shown, the base station (gNB) can be divided into gNB-CU-CP, gNB-CU-UP, and gNB-DU.

[0116] In the 5G network architecture, communication between the gNB-DU and gNB-CU is achieved through the F1 interface. The F1 interface connects the gNB-DU and gNB-CU, supporting data transmission between the user plane and control plane. Figure 9 As shown, a key step in establishing the above connection is the F1 interface establishment process, which begins with the F1 SETUP REQUEST message sent by the gNB-DU, followed by the gNB-CU responding with an F1 SETUP RESPONSE message.

[0117] In the above embodiments of the physical random access channel report reporting method, the corresponding physical device on the network side can be a base station or a base station central unit (gNB-CU).

[0118] The physical random access channel report reporting method performed by a user equipment (UE) according to embodiments of this disclosure includes: the UE determining random access information; receiving a first request message from the network side, the first request message carrying first indication information; the first indication information instructing the UE to report random access procedure information or containing highly relevant random access procedure information; and the UE sending a first response message to the network side, the first response message carrying at least one second random access report or a first random access report. The detailed process is as follows:

[0119] The network in the above embodiments includes at least one wireless node and a core network node, wherein at least one wireless node is a master node, and if there are other wireless nodes, the remaining wireless nodes are auxiliary nodes. The master node and auxiliary nodes may use the same or different wireless standards, and the wireless standards may be 4G, 5G or 6G.

[0120] User equipment determines random access information when it successfully executes a random access procedure initialized with a 4-step or 2-step RA type, or when it fails or successfully completes an on-demand system information acquisition procedure in the RRC_IDLE or RRC_INACTIVE state, or when the RA-SDT operation fails or successfully completes.

[0122] User equipment stores random access information; user equipment may discard the stored random access report information immediately after the last successful random access process or after a failed or successfully completed on-demand system information acquisition process.

[0123] The user equipment reports its capabilities to the network. These capabilities include highly relevant machine access process information that supports the user equipment.

[0124] The network sends a first request message to the user equipment, which carries first indication information. The first indication information is used to instruct the user equipment to report random access procedure information or highly relevant access procedure information. The first request message can be a UEInformationRequest in a 5G system or a message for obtaining user information in a 6G system.

[0125] After receiving the first request message, if the first request message carries first indication information and has available random access related information, the user equipment includes a second random access report in the first response message; the second random access report is determined by the first random access report; the first random access report can be determined by the random access information previously stored. The first indication information is used to instruct the user equipment to report random access procedure information or to include highly relevant random access procedure information.

[0126] After confirming the successful delivery of the first RRC response message at the underlying layer, the random access information is discarded. The underlying layer includes at least one of the MAC, RLC, and PDCP layers.

[0127] When the secondary node receives the first response message, the secondary node sends the second information to the primary node through the interface between the secondary node and the primary node. The second information includes at least one of random access related information and at least one of wireless standard information.

[0128] The network adjusts the uplink parameter configuration based on random access information fed back by at least one user equipment, including at least one of the following: uplink SUL threshold value, uplink random access format, SSB beam direction, and terminal uplink power configuration. The SSB beam direction includes an SSB beam pointing towards the air or the ground, or the electronic tilt angle of the SSB beam.

[0129] Figure 10 This diagram illustrates a flowchart of a physical random access channel report reporting method performed by a user equipment according to an embodiment of the present disclosure, such as... Figure 10 As shown, the physical random access channel report reporting method includes S1001-S1003.
