Description

Technical Field

[0001] The present invention relates to the field of wireless link technology, and in particular to a wireless link monitoring method, system, equipment and medium. Background Art

[0002] With the widespread application of NR (New Radio), more and more scenarios have put forward higher requirements for anti-interference. The NR synchronization signal block (Synchronization Signal and PBCH block, SSB) carries basic information, which includes three parts: primary synchronization signal (PSS), secondary synchronization signal (SSS) and PBCH (Physical broadcast channel). After the idle terminal correctly receives the SSB and then detects each broadcast message, it can initiate random access. For the terminal that has already accessed, the wireless link monitoring reference signal will be configured according to the base station, and the downlink channel link quality between the base station and the terminal will be detected to maintain the RRC (Radio Resource Control) link state.

[0003] When the frequency band where the SSB is located is interfered with, the terminal will be unable to access, greatly affecting the user experience. The patent with publication number CN113965975A provides a method for sending SSB in a frequency division multiplexing manner. When a single SSB is interfered with, the terminal can correctly receive the SSB at other frequency domain positions, thereby improving the success rate of terminal access. However, for terminals that have already accessed and use the access-selected SSB as a wireless link reference signal for monitoring the link quality between base station terminals, after the SSB is interfered with, it will still trigger a wireless link failure. The interference will greatly increase the probability of the terminal failing to re-access, resulting in interruption of service transmission or even terminal disconnection, seriously affecting the user experience. Summary of the invention

[0004] The purpose of the present invention is to address the deficiencies of the above-mentioned prior art and provide a wireless link monitoring method, system, device and medium to solve the problem in the prior art that for terminals that have already accessed, the SSB selected for access is used as a wireless link reference signal for monitoring the link quality between base station terminals. After the SSB is interfered with, the wireless link failure will still be triggered. The interference will greatly increase the probability of the terminal failing to re-access, resulting in interruption of service transmission and even terminal disconnection, which verifies the problem of affecting user experience.

[0021] If the frequency domain SSB index reselected by the terminal is different from the frequency domain SSB index selected for initial access, the frequency domain SSB index selected for initial access is interfered with; otherwise, the frequency domain SSB index selected for initial access is not interfered with;

[0041] The following is a clear and complete description of the technical solutions of the embodiments of the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0042] like Figure 1 to Figure 4 As shown, the present invention provides a wireless link monitoring method for description below, which specifically includes the following steps:

[0043] Step S1: The base station sends multiple synchronization signal blocks SSB by frequency division.

[0044] One or more synchronization signal blocks SSB are sent at different time domain positions, and multiple synchronization signal blocks SSB are sent at different frequency domain positions. Each SSB has a corresponding different control resource set coresetzero.

[0045] In one method, the base station performs network planning based on the estimated interference situation and determines to send N frequency domain SSBs, K time domain SSBs and L CSI-RS (Channel state information reference signal) as wireless link monitoring reference signals. The SSB frequency point setting meets the requirements of the 3GPP specification.

[0046] Another way is to determine the maximum number of SSBs N sent within the BWP bandwidth based on the SSB synchronization grid and BWP bandwidth defined in the 3GPP specification; the specific expression is:

[0047]

[0048] in, are the number of RBs for BWP and SSB respectively; is the number of subcarriers per RB; Δf BWP , Δf SSB are BWP subcarrier spacing and SSB subcarrier spacing respectively; step and numofM are the number of possible values ​​of M in the SSB synchronization grid step and SSB frequency calculation formula respectively, as shown in Table 1:

[0049] Table 1

[0050] Frequency range step numofM 0–3000MHz 1200kHz 3 3000–24250MHz 1440kHz 1 24250-100000MHz 17.28MHz 1

[0051] Traverse the BWP bandwidth, N does not exceed 256.

[0052] 8 bits are used to represent the frequency domain indexes of all N SSBs within the BWP bandwidth that conform to the SSB synchronization grid defined by the 3GPP specification and ensure that the entire SSB falls within the BWP. The frequencies are numbered from 0 to N-1 from low to high.

[0053] Step S2: The base station determines the frequency domain SSB index of the initial access of the terminal. If the terminal re-accesses when the wireless link fails or the beam transmission fails, the frequency domain SSB index is reselected from the configured multiple SSBs, and when the frequency domain SSB index of the initial access is different from the reselected frequency domain SSB index, the interference conditions of the SSBs in different frequency domains are obtained, and the wireless link monitoring reference signal is configured for the terminal according to the interference conditions of the SSBs in different frequency domains.

[0054] The base station determines the interference of SSB in different frequency domains through the terminal re-access process, such as Figure 2 As shown:

[0055] The configuration of M and N is constrained by the terminal processing capability. In a typical case, J takes a value of 2, K takes a value of 1, and L takes a value of 0 (indicating that CSI-RS is not configured).

[0056] Furthermore, a method for configuring a radio link monitoring reference signal is provided, that is, a new field ssb-Index-frequency is added in RadioLinkMonitoringRS, and the format is as follows:

[0057] RadioLinkMonitoringRS::=SEQUENCE{

[0058] radioLinkMonitoringRS-Id RadioLinkMonitoringRS-Id,

[0059] purpose ENUMERATED{beamFailure,rlf,both},

[0060] detectionResource CHOICE{

[0061] ssb-Index SSB-Index,

[0062] csi-RS-Index NZP-CSI-RS-ResourceId

[0063] ssb-Index-frequencyARFCN-ValueNR OPTIONAL,

[0064] },

[0065] }

[0066] Among them, ssb-Index-frequency indicates the SSB frequency information, which is described as follows:

[0067] When detectionResource is configured as csi-RS-Index, ssb-Index-frequency is the default.

[0068] When detectionResource is configured as ssb-Index and ssb-Index-frequency is not configured, ssb-Index-frequency indicates that the configured SSB frequency is the SSB selected for initial access; and the SSB frequency remains unchanged until a new configuration is obtained.

[0069] When detectionResource is configured as ssb-Index and ssb-Index-frequency is configured, ssb-Index-frequency indicates that the SSB frequency represented by ARFCN is configured.

[0070] Another implementation method provides a method for configuring a radio link monitoring reference signal, that is, adding a new field ssb-Index-frequency in RadioLinkMonitoringRS, with the following format:

[0071] RadioLinkMonitoringRS::=SEQUENCE{

[0072] radioLinkMonitoringRS-Id RadioLinkMonitoringRS-Id,

[0073] purpose ENUMERATED{beamFailure,rlf,both},

[0074] detectionResource CHOICE{

[0075] ssb-Index SSB-Index,

[0076] csi-RS-Index NZP-CSI-RS-ResourceId

[0077] ssb-Index-frequency BIT STRING(SIZE(8))OPTIONAL,

[0078] },

[0079] }

[0080] Among them, ssb-Index-frequency indicates the SSB frequency information, which is described as follows:

[0081] When detectionResource is configured as csi-RS-Index, ssb-Index-frequency is the default. When detectionResource is configured as ssb-Index and ssb-Index-frequency is not configured,

[0082] ssb-Index-frequency indicates that the configured SSB frequency is the SSB selected for initial access; and the SSB frequency remains unchanged until a new configuration is obtained;

[0083] When detectionResource is configured as ssb-Index and ssb-Index-frequency is configured,

[0084] ssb-Index-frequency indicates that the frequency domain SSB index represented by the bitmap is configured, and the corresponding frequency point is calculated by formula 1.

[0085] like Figure 2 Flowchart for determining SSB interference situations in different frequency domains for a base station.

[0086] The base station determines and maintains the frequency domain SSB index for initial access by the terminal, including:

[0087] According to the control resource sets corresponding to different frequency domain positions of different frequency domain SSBs, the base station determines the frequency domain SSB index selected by the terminal access according to the frequency domain position scheduled by the MSG2 random access response and the MSG4 RRC establishment request message of the scheduled terminal. Among them, the frequency domain positions scheduled by MSG2 and MSG4 are within the bandwidth range of the control resource set coresetzero corresponding to the SSB.

[0088] Determine the frequency domain SSB index reselected by the terminal, and when the frequency domain SSB index initially accessed is different from the reselected frequency domain SSB index, obtain the interference conditions of SSBs in different frequency domains, including:

[0089] During the re-access process based on re-establishment or beam failure, the base station determines the frequency domain SSB index of the terminal for re-establishment access selection based on the frequency domain position of the MSG2 scheduling of the scheduled terminal and the cell radio network temporary identifier (Cell-Radio Network Temporary Identifier, C-RNTI) of the terminal obtained in the re-establishment request; wherein the frequency domain position of the MSG2 scheduling is within the bandwidth range of the control resource set coresetzero corresponding to the SSB.

[0090] If the frequency domain SSB index reselected by the terminal is different from the frequency domain SSB index selected for initial access, the frequency domain SSB index selected for initial access is interfered with; otherwise, the frequency domain SSB index selected for initial access is not interfered with.

[0091] Among them, the frequency domain SSB index reselected by the terminal is not interfered with; before receiving the re-establishment request message from the terminal, the base station considers that all frequency domain SSBs are not interfered with.

[0092] Configure the wireless link monitoring reference signal for the terminal according to the SSB interference situation in different frequency domains, including:

[0093] The base station selects J frequency-domain SSBs that are not interfered with, K SSBs with different time domains, and L CSI-RSs from N frequency-domain SSBs and configures them to the terminal as wireless link monitoring reference signals.

[0094] Step S3: The base station monitors the radio link according to the radio link monitoring reference signal.

[0095] The terminal searches for SSB in the frequency domain and selects SSB to initiate initial access:

[0096] For the selected SSB, the RSRP measured by the terminal must exceed the first threshold value.

[0097] The first threshold value is obtained from the remaining minimum system information SIB1 sent by the base station.

[0098] The terminal selects the PRACH resource corresponding to the SSB according to the time domain index of the SSB and sends a PRACH signal (ie, MSG1).

[0099] Wireless link monitoring after terminal access:

[0100] The terminal detects and monitors the wireless link from the base station to the terminal according to P=J×K+L wireless link monitoring reference signals configured by the base station; the terminal measures the RSRP (Reference Signal Receiving Power) of the P wireless link monitoring reference signals, and determines whether the conditions of wireless link failure or beam failure are met according to the existing technology.

[0101] After a radio link fails, reselect the frequency domain SSB index from the configured multiple SSBs, including:

[0102] After the terminal determines that the wireless link fails or the beam fails, or for other reasons, it selects an SSB from the configured J×K SSBs whose measured RSRP exceeds the first threshold value to initiate reaccess.

[0103] Among the configured J×K SSBs, the SSB with the largest RSRP is selected from all SSBs whose measured RSRP exceeds the first threshold value to initiate reaccess.

[0104] Alternatively, if the RSRP measured in the configured J×K SSBs are all less than the first threshold value, the terminal re-searches the SSB within the cell bandwidth and selects the SSB with the largest RSRP to initiate re-access; wherein the first threshold value is obtained from the remaining minimum system information SIB1 sent by the base station.

[0105] Based on the above method, the present invention provides a wireless link monitoring system, including: an initial sending module, a monitoring module and a selection module.

[0106] Among them, the initial sending module is used by the base station to send multiple synchronization signal blocks SSB by frequency division; the monitoring module is used by the base station to determine the frequency domain SSB index of the terminal's initial access. If the terminal re-accesses when the wireless link fails or the beam transmission fails, the frequency domain SSB index is reselected from the configured multiple SSBs, and when the frequency domain SSB index of the initial access is different from the reselected frequency domain SSB index, the interference conditions of the SSBs in different frequency domains are obtained, and the wireless link monitoring reference signal is configured for the terminal according to the interference conditions of the SSBs in different frequency domains; the selection module is used by the base station to monitor the wireless link according to the wireless link monitoring reference signal.

[0107] The present invention also provides a computer device, including a memory and a processor, wherein a program is stored in the memory, and when the program is executed by the processor, the processor executes the steps of a wireless link monitoring method.

[0108] In accordance with the disclosed embodiments, a computing device may communicate with one or more external devices (e.g., keyboards, pointing devices, Bluetooth communications, etc.), or with any device (e.g., routers, modems, etc.) that enables a computing device to communicate with one or more other computing devices.

[0109] The present invention also provides a storage medium on which a computer program is stored. When the computer program is executed by a processor, the steps of a wireless link monitoring method are implemented.

[0110] According to the disclosed embodiments, the storage medium may be a non-volatile computer-readable storage medium, such as but not limited to: a portable computer disk, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), a portable compact disk read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination thereof. In the present invention, the storage medium may be any tangible medium containing or storing a program that may be used by or in conjunction with an instruction execution system, apparatus, or device.

[0111] The above content is a further detailed description of the present invention in combination with a specific preferred embodiment. For technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the protection scope of the present invention.
