[0024] The following will clearly and completely describe the technical solutions of this disclosure in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of this disclosure, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.
[0025] It should be noted that, in this disclosure, words such as "exemplary" or "for example" are used to describe examples, illustrations, or explanations. Any embodiment or design described in this disclosure using words such as "exemplary" or "for example" should not be interpreted as being more preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.
[0026] In the following, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Thus, a feature defined by the terms "first," "second," etc. may explicitly or implicitly include one or more of the features.
[0027] In this disclosure, unless otherwise specified, " / " means "or." For example, A / B can mean either A or B. "And / or" is used herein solely to describe an association between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: only A, only B, and both A and B. Furthermore, "at least one" means one or more, and "a plurality" means two or more.
[0028] With the explosive growth of data traffic, millimeter wave (mmWave), with its abundant available frequency bands, has become a key technology for fifth-generation mobile communications. The first significant challenge in implementing mmWave communications is path loss. To compensate for the severe path loss associated with mmWave transmission, mmWave base stations (BSs) typically employ large-scale antenna arrays for narrow-beam transmission, effectively concentrating transmission energy in a single area or direction. However, the directional nature of mmWave transmission is highly sensitive to obstruction, which can even lead to connection interruptions. This poses new challenges to establishing and maintaining mmWave links. To address this, relay reflector equipment, such as RIS and NCR, has been integrated into mmWave cellular systems.
[0029] Relay reflectors such as RIS / NCR are artificial electromagnetic materials with programmable electromagnetic properties. They consist of a large number of low-cost reflector arrays. By controlling the phase and amplitude of each array, the direction of the outgoing beam focus can be regulated, thereby changing the propagation path of the electromagnetic wave and achieving control over the wireless network environment. Traditional wireless technologies generally perform signal processing at the transmit and receive ends to adapt to dynamic and uncontrollable wireless network environments. RIS / NCR, however, can proactively correct wireless channels through controllable intelligent signal reflection technology. Therefore, RIS / NCR provides new freedom for further improving wireless link performance and paves the way for the realization of intelligent, programmable wireless environments.
[0030] In millimeter-wave cellular systems, obstruction caused by factors such as terrain and objects can severely degrade wireless link quality and even cause link interruption. RIS / NCR, by its ability to modify the electromagnetic wave transmission environment, has the potential to become a new approach to addressing millimeter-wave communication obstruction. When the wireless link between user equipment and the base station is blocked, RIC / NCR can be used to adjust the phase of the electromagnetic wave transmission path, bypassing the obstruction to reach the user, thereby improving communication quality and the coverage capability of the millimeter-wave system.
[0031] As can be seen, RIS and NCR, as controllable network devices, possess certain attributes of mobile terminals, but their controlled characteristics differ from those of mobile terminals. RIS and NCR require higher levels of control robustness and operational reliability to ensure stable, high-quality coverage for mobile terminals. To achieve this, the network needs to manage the RIS / NCR's operating status in real time. However, the relevant technology lacks a technical solution for managing the status of wireless relay devices.
[0032] To address the above technical issues, an embodiment of the present disclosure provides an exception handling method, the concept of which is as follows: a first node determines a processing strategy for handling an abnormal state of a wireless relay device and sends the processing strategy to the wireless relay device; accordingly, the wireless relay device receives the processing strategy for handling an abnormal state of the wireless relay device sent by the first node. In this way, the wireless relay device can manage its own operating status in real time. For example, when an abnormal state occurs in the wireless relay device, it can perform self-processing according to the processing strategy, which can improve the control robustness and operating reliability of the wireless relay device, thereby achieving stable and high-quality coverage for mobile terminals.
[0033] The communication system provided by the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.
[0034] 1 , which is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure, as shown in FIG1 , the communication system includes: a base station 110 , a wireless relay device 120 , and a terminal device 130 .
[0035] The first node or base station 110 is configured to transmit and receive electromagnetic waves.
[0036] Exemplarily, the base station 110 may be a next generation Node B (gNB).
[0037] In some embodiments, as shown in FIG2 , a base station 110 includes a controller 111 and an antenna 112. The controller 111 is configured to manage wireless communication interfaces and wireless channels. The antenna 112 is configured to transmit and receive electromagnetic waves.
[0038] Exemplarily, the antenna 112 may transmit electromagnetic waves to the wireless relay device 120 according to the control of the controller 111 .
[0039] In some embodiments, the base station 110 may further include a communication interface 113 for exchanging information with other devices. For example, the base station 110 may exchange information with the wireless relay device 120 via the communication interface 113. The base station 110 may also exchange information with other devices such as network servers via the communication interface 113.
[0040] In some embodiments, the base station 110 may further include a memory 114 for storing data. For example, the memory 114 may be used to store a codebook.
[0041] Exemplarily, the memory 114 may be a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a random access memory (RAM) or other type of dynamic storage device that can store information and instructions, an electrically erasable programmable read-only memory (EEPROM), a disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto.
[0042] The wireless relay device 120 is used to relay or forward the electromagnetic waves transmitted by the base station 110 .
[0043] Exemplarily, the wireless relay device 120 may be a RIS, an NCR, an intelligent relay device, or other devices with signal forwarding and relaying functions.
[0044] In some embodiments, as shown in FIG3 , the wireless relay device 120 includes a wireless signal relay module (RIS-Forwarding, RIS-Fwd) 121 and a control module (RIS-Mobile-Termination, RIS-MT) 122 .
[0045] The wireless signal relay module 121 includes an antenna reflection array composed of antenna elements, which is used to adjust the incident beam in different ways according to the codebooks of different antenna elements (the codebooks are used to control the spectrum, phase, amplitude, and polarization values of each antenna element), so that the outgoing beam can achieve changes in amplitude, width, frequency shift, and output angle, as well as changes in single-beam reflection, multi-beam reflection, diffuse scattering, refraction, transmission, etc.
[0046] Exemplarily, the wireless signal relay module 121 can reflect the incoming beam to a specified area (e.g., a base station coverage blind spot) based on the beam indication (i.e., codebook) provided by the control module 122 to serve the UE (user equipment) in the area. For example, in an embodiment of the present disclosure, the wireless signal relay module 121 can adjust the incoming beam from the base station 110 to an outgoing beam directed toward the terminal device 130.
[0047] The control module 122 includes a controller 122 - 1 , a memory 122 - 2 , and a communication interface 122 - 3 .
[0048] The controller 122 - 1 is configured to transmit a relay beam indication (ie, a codebook) to the wireless signal relay module 121 and control the working state of the wireless signal relay module 121 .
[0049] Exemplarily, the controller 122-1 can control the working state of the wireless signal relay module 121 according to the instructions of the base station 110, such as: switch state (controlling the working or non-working of the wireless signal relay module 121, etc.); power control (controlling the reflected beam amplitude of the wireless signal relay module 121); relay beam indication (code book of the antenna array of the wireless signal relay module 121).
[0050] It can be understood that a codebook represents a relative relationship between an incident beam and an outgoing beam. Therefore, for a reflectarray, a codebook can also be called a beam indication.
[0051] The memory 122-2 is configured to store a codebook.
[0052] The communication interface 122 - 3 is used to exchange information with other devices. For example, the control module 122 can exchange information with the base station 110 through the communication interface 122 - 3 .
[0053] Exemplarily, the control module 122 may receive control information (e.g., codebook update information, etc.) sent by the base station 110 through the communication interface 122-3, and send RIS working status information, RIS configuration information, and RIS codebook set, etc. to the base station through the communication interface 122-3.
[0054] Exemplarily, the communication interface 122 - 3 can interact with other devices through narrowband Internet of Things (NB-IoT), fifth-generation mobile communication technology (5G), wireless fidelity (WiFi), etc.
[0055] The terminal device 130 is configured to communicate using the electromagnetic waves radiated by the wireless relay device 120 .
[0056] For example, the terminal device 130 may be a UE, such as a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (PDA), an augmented reality (AR) or virtual reality (VR) device, etc. The embodiments of the present disclosure do not impose any particular limitation on the specific form of the terminal device 130.
[0057] In some embodiments, the communication system further includes a wireless relay device management entity configured to manage a codebook library of the wireless relay device, deployment information of the wireless relay device, and authentication of the wireless relay device. The wireless relay device management entity may be deployed in a base station, a core network domain, a core network element, an operation administration and maintenance backend (OAM), a radio access network (RAN) domain, and the like. Exemplarily, the core network element may include an access and mobility management function (AMF), a service management function (SMF), a policy control function (PCF), a user plane function (UPF), an application function (AF), and the like.
[0058] It is understandable that the application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.
[0059] The following describes the exception handling method provided by the embodiment of the present disclosure.
[0060] The present disclosure provides an exception handling method, as shown in FIG4 , which includes the following S201 and S202 .
[0061] In S201 , the first node determines a processing strategy for processing an abnormal state of a wireless relay device.
[0062] The first node may be a network-side node. For example, the first node includes any one of the following: an access network device, a core network device, or a management entity of a wireless relay device.
[0063] In some embodiments, the abnormal state of the wireless relay device includes the following five situations.
[0064] Abnormal status 1: The connection between the control module and the wireless signal relay module of the wireless relay device is abnormal.
[0065] In some embodiments, the connection abnormality between the control module and the wireless signal relay module includes at least one of the following: the connection between the control module and the wireless signal relay module is interrupted; the packet error rate or packet loss rate between the control module and the wireless signal relay module is higher than the first preset threshold; the control module's control over the wireless signal relay module is abnormal.
[0066] Exemplarily, the control abnormality of the wireless signal relay module by the above-mentioned control module includes at least one of the following: the control code book configuration of at least part of the antenna reflection array in the wireless signal relay module fails, for example, the control code book configuration of the overall antenna reflection array in the wireless signal relay module fails, or the control code book configuration of part of the antenna array in the wireless signal relay module fails; the panel attitude adjustment of the wireless signal relay module fails or is not adjusted in place, for example, the azimuth adjustment of the panel of the wireless signal relay module fails or is not adjusted in place, or the tilt and / or pitch angle adjustment of the panel of the wireless signal relay module fails or is not adjusted in place; the switch (on / off) switching of the wireless signal relay module fails; the power adjustment of the wireless signal relay module fails or is not in place; the status query of the wireless signal relay module fails; the control code book read back of the antenna reflection array of the wireless signal relay module fails; the read-back value of the control code book of the antenna reflection array of the wireless signal relay module is inconsistent with the configuration value.
[0067] Abnormal state 2: The connection between the first node and the control module of the wireless relay device is abnormal.
[0068] In some embodiments, the connection abnormality between the first node and the control module includes at least one of the following: the beam arrival angle or beam arrival direction measured by the control module exceeds a first preset range, the beam arrival angle refers to the angle of the beam emitted by the base station when it reaches the antenna panel of the wireless signal relay module, and the beam arrival direction refers to the direction of the beam emitted by the base station when it reaches the antenna panel of the wireless signal relay module; the wireless link between the first node and the control module is abnormal; the control module fails to perform cell reselection; the control module does not reside in a high-priority cell or a preset target cell after performing cell reselection; the control module fails to successfully access the access network node; the number of control module access failures is greater than or equal to a second preset threshold; the control module does not access a high-priority cell or a preset target cell.
[0069] Exemplarily, the wireless link abnormality between the first node and the control module includes at least one of the following: wireless link failure; the frequency of wireless link failure exceeds a third preset threshold; beam failure; the frequency of beam failure exceeds a fourth preset threshold; the first node fails to send control information to the control module; the control module fails to send status information to the first node.
[0070] Abnormal state 3: The connection between the control module of the wireless relay device and the second node is abnormal.
[0071] The second node may be a network-side node. For example, the second node may include any of the following: an access network device, a core network device, or a management entity of a wireless relay device. It is understood that the first node and the second node are different nodes. For example, if the first node is an access network device, the second node may be a management entity of a core network device or a wireless relay device.
[0072] In some embodiments, the connection abnormality between the control module and the second node includes at least one of the following: the second node fails to send control information or management policy to the control module, and the management policy may include a processing strategy for handling abnormal status of the wireless relay device; the control module fails to send status information to the second node.
[0073] Abnormal status 4: The control module is abnormal or the wireless signal relay module is abnormal.
[0074] In some embodiments, the control module abnormality includes at least one of the following: the standby voltage or standby power consumption exceeds the fifth preset threshold; the operating voltage or operating power consumption exceeds the sixth preset threshold; the charging power is lower than the seventh preset threshold; the charging power is higher than the eighth preset threshold; the remaining power or remaining working time is lower than the ninth preset threshold; one or more of the control module's power-on time, power-off time, idle operation time, and connected operation time do not comply with the preset schedule.
[0075] In some embodiments, the abnormality of the wireless signal relay module includes at least one of the following: the standby voltage or standby power consumption exceeds the tenth preset threshold; the working voltage or working power consumption exceeds the eleventh preset threshold; the working voltage or standby voltage of at least part of the antenna units in the antenna reflection array is abnormal; the charging power is lower than the twelfth preset threshold; the charging power is higher than the thirteenth preset threshold; the remaining power or remaining working time is lower than the fourteenth preset threshold; one or more of the power-on time, power-off time and standby operation time of the wireless signal relay module do not comply with the preset schedule.
[0076] Abnormal status 5: The security status of the wireless relay device is abnormal.
[0077] In some embodiments, the abnormal security status of the wireless relay device includes: an identifier of a cell to which the control module of the wireless relay device is connected or resides is not in a preset cell list.
[0078] It should be noted that the various preset values defined in the above-mentioned exception types, such as preset thresholds (including the first preset threshold to the fourteenth preset threshold), preset ranges, preset timetables and other preset parameter values, are all pre-configured to the wireless relay device by the network side node through signaling.
[0079] In some embodiments, the processing strategies for handling abnormal status of the wireless relay device include the following five processing strategies.
[0080] Processing strategy 1: The first processing strategy for the abnormal connection between the control module and the wireless signal relay module.
[0081] In some embodiments, the first processing strategy includes at least one of the following: a first self-processing strategy of the control module; and the control module generating and reporting a first abnormal status report.
[0082] In some embodiments, the first self-processing strategy includes at least one of the following: the control module turns off at least part of the antenna reflection array in the wireless signal relay module, for example, the control module turns off the wireless signal relay module, or the control module turns off part of the antenna array in the wireless signal relay module; the control module adjusts the wireless signal relay module to standby mode.
[0083] Exemplarily, when the abnormal connection condition between the control module and the wireless signal relay module is other abnormal conditions other than "connection interruption" and "failure to switch the switch (on / off) of the wireless signal relay module", the control module can shut down the wireless signal relay module, or the control module can adjust the wireless signal relay module to a standby state. It is understandable that when the abnormal connection condition between the control module and the wireless signal relay module is other abnormal conditions other than "connection interruption" and "failure to switch the switch (on / off) of the wireless signal relay module", the wireless signal relay module is in an uncontrollable state, so the wireless signal relay module can be shut down, or the wireless signal relay module can be adjusted to a standby state to avoid causing a negative gain in coverage.
[0084] Exemplarily, when the abnormal connection conditions between the control module and the wireless signal relay module include: "the control code book configuration of part of the antenna reflection array fails" and "the value read back from the control code book of the antenna reflection array of the wireless signal relay module is inconsistent with the configuration value", the control module shuts down part of the antenna array in the wireless signal relay module.
[0085] In some embodiments, the first abnormal status report includes at least one of the following: abnormality type, abnormality occurrence time (including the occurrence time of each abnormality type), first abnormality value, and operation log of the wireless relay device.
[0086] The first abnormal value includes at least one of the following: packet error rate or packet loss rate; the range of the antenna reflection array corresponding to the control codebook where the configuration failed; the panel attitude adjustment feedback value of the wireless signal relay module; the antenna reflection array control codebook readback value of the wireless signal relay module; and the identification of at least part of the antenna reflection array that has been turned off.
[0087] Processing strategy 2: a second processing strategy for the abnormal connection between the first node and the control module.
[0088] In some embodiments, the second processing strategy includes at least one of the following: a first constraint strategy that the control module must follow when accessing the access network node; a second self-processing strategy of the control module; and the control module generating and reporting a second abnormal status report.
[0089] In some embodiments, the first constraint strategy includes at least one of the following: a list of first target cells that the control module allows access or reselection; a priority of the target cells that the control module allows access or reselection; a list of second target cells that the wireless signal relay module allows relaying; the number of access failure retries of the control module; and the access failure retry time interval of the control module.
[0090] For example, when the first constraint strategy includes a first target cell list, the control module is only allowed to access or reselect cells in the first target cell list when accessing or reselecting a cell. It is understood that when a wireless relay device is deployed, due to the limited range of incident angles of the beam, the optimal source sites that the wireless relay device can serve are limited and preset. Therefore, if the control module of the wireless relay device accesses the wrong site, coverage of the target blind spot or weak area cannot be achieved.
[0091] Exemplarily, when the first constraint strategy includes the priority of the target cell allowed to be accessed or reselected, when the number of sites that the wireless relay device can serve is greater than one, the wireless relay device can be constrained to select the site for access service based on the priority of the target cell allowed to be accessed or reselected.
[0092] For example, if the first constraint strategy includes a second target cell list, the wireless signal relay module is only allowed to relay beams from cells in the second target cell list. It is understandable that since the wireless signal relay module can only achieve coverage of blind or weak areas by relaying the beam of the correct cell, the reflector module can still relay the beam of the correct cell even if the reflector module connects to the wrong cell, as long as the cell supports obtaining control information or beam switching instructions from the correct cell. Therefore, the above constraint strategy only constrains the wireless signal relay module and does not restrict the control module.
[0093] In some embodiments, the wireless relay device serves as a network device supporting coverage improvement, and the number of access failure retries of its control module is greater than that of an ordinary terminal device, thereby ensuring access reliability.
[0094] In some embodiments, the second self-processing strategy includes at least one of the following: the control module shuts down at least part of the antenna reflection array in the wireless signal relay module, for example, the control module shuts down the wireless signal relay module, or the control module shuts down part of the antenna array in the wireless signal relay module; the control module adjusts the wireless signal relay module to a standby state; the control module reconnects to the network-side node and turns on the wireless signal relay module; if the cell accessed by the control module does not comply with the first constraint strategy, re-initiates access according to the target cell provided by the first constraint strategy; the control module maintains the current working state and codebook of the wireless signal relay module unchanged; the control module switches the codebook of the wireless signal relay module to a first preset codebook, the first preset codebook being used to adjust the direction of the outgoing beam of the wireless signal relay module including: the first preset codebook being used to adjust the outgoing beam of the wireless signal relay module to point to the target area; the control module switches the codebook of the wireless signal relay module to a second preset codebook, the second preset codebook being used to adjust the coverage range of the outgoing beam of the wireless signal relay module including: the second preset codebook being used to adjust the coverage range of the outgoing beam of the wireless signal relay module to increase it to a preset range.
[0095] For example, in response to any one or more of the abnormal conditions in Abnormal State 2, the control module can shut down the wireless signal relay module or adjust the wireless signal relay module to a standby state. It is understood that this handling strategy is a conservative strategy, i.e., it is assumed that each abnormal condition in Abnormal State 2 means that the source signal reflected by the wireless signal relay module is abnormal.
[0096] Exemplarily, the above-mentioned processing strategy of "the control module keeps the current working state and codebook of the wireless signal relay module unchanged" is applicable to scenarios where the codebook does not need to be adjusted frequently. In this way, even if the connection between the control module and the first node fails, the wireless signal relay module can maintain the current reflection state and will not cause additional negative gain.
[0097] Exemplarily, the aforementioned processing strategy of "the control module switching the codebook of the wireless signal relay module to the first preset codebook" is a compromise between "disabling the wireless relay device" and "maintaining the wireless relay device." Specifically, when the codebook of the wireless signal relay module is switched to the first preset codebook, the reflection direction and reflection beam of the wireless signal relay device can point toward a target area. The target area is a preset priority coverage area. The target area can be the most reliable area. When the reflection direction and reflection beam of the wireless signal relay device point toward the target area, service to the UE can be maintained to the greatest extent possible without incurring additional negative gain.
[0098] Exemplarily, the above-mentioned processing strategy of "the control module switches the codebook of the wireless signal relay module to the second preset codebook" is a compromise between "turning off the wireless relay device" and "maintaining the wireless relay device", that is, when the codebook of the wireless signal relay module is switched to the second preset codebook, the outgoing beam coverage range of the wireless signal relay module can be adjusted to increase it to the preset range. In this way, when the control module loses connection with the first node, the coverage performance of the wireless relay device for blind spots or weak areas can be prioritized.
[0099] In some embodiments, the second abnormal status report includes at least one of the following: abnormality type, abnormality occurrence time (including the occurrence time of each abnormality type), second abnormality value, and operation log of the wireless relay device.
[0100] The second abnormal value includes at least one of the following: an abnormal measurement value of the beam arrival angle or beam arrival direction; the frequency of wireless link failure; the frequency of beam failure; the number or frequency of failures in sending status information of the wireless relay device, and the failure log; the frequency of reselection failures; the identification of the resident cell; and the identification of the access cell.
[0101] Exemplarily, the first node can identify the direction from which the accessed wireless signal (or beam) comes based on the measured value of the abnormal beam arrival angle or beam arrival direction, and whether it complies with the incident beam angle range preset when the wireless signal relay module is deployed. If it exceeds this range, the wireless signal relay module cannot achieve coverage of the preset blind spot.
[0102] Processing strategy 3: a third processing strategy for the abnormal connection between the control module and the second node.
[0103] In some embodiments, the third processing strategy includes at least one of the following: a first constraint strategy that the control module must follow when accessing the access network node; the control module generates and reports a second abnormal status report; and a second self-processing strategy of the control module.
[0104] Processing strategy 4: The fourth processing strategy for control module abnormality or wireless signal relay module abnormality.
[0105] In some embodiments, the fourth processing strategy includes at least one of the following: a second constraint strategy that the control module or wireless signal relay module must follow during operation; a third self-processing strategy of the control module; and the control module generating and reporting a third abnormal status report.
[0106] In some embodiments, the second constraint strategy includes at least one of the following: the on time, off time and standby time of the wireless signal relay module follow a preset schedule; the on time, off time, standby time and connection time of the control module follow a preset schedule.
[0107] It is understood that the second constraint strategy described above is applicable to scenarios where the operator of the wireless relay device schedules the operating status of the wireless relay device during busy / off-peak hours, thereby facilitating energy conservation for the wireless relay device. If the operation of the wireless signal relay module or the control module does not conform to the preset schedule, a status report is submitted. The status report may include operation log records for the time period that does not conform to the preset schedule.
[0108] In some embodiments, the third self-processing strategy includes at least one of the following: the control module turns off at least part of the antenna reflection array in the wireless signal relay module, for example, the control module turns off the wireless signal relay module, or the control module turns off part of the antenna array in the wireless signal relay module; the control module adjusts the wireless signal relay module to standby mode.
[0109] For example, when the operating status of the control module or the wireless signal relay module is abnormal, it means that the components of the wireless relay device are potentially damaged, and maintaining the operation of the wireless relay device may bring additional negative gain. Therefore, the control module can shut down the wireless signal relay module.
[0110] For example, when the operating voltage or standby voltage of some antenna elements or antenna units of the antenna reflective array is abnormal, the control module may shut down part of the antenna array in the wireless signal relay module.
[0111] For example, when the standby voltage or standby power consumption of the control module or the wireless signal relay module exceeds a preset range, the control module may adjust the wireless signal relay module to a standby state.
[0112] In some embodiments, the third abnormal status report includes at least one of the following: abnormality type, abnormality occurrence time (including the occurrence time of each abnormality type), a third abnormality value, and an operation log of the wireless relay device.
[0113] The third abnormal value includes at least one of the following: voltage, power consumption, charging power, remaining power or remaining working time, an identifier of an antenna reflection array with abnormal voltage, and an identifier of a turned-off antenna reflection array.
[0114] Processing strategy 5: The fifth processing strategy for abnormal security status of wireless relay devices.
[0115] In some embodiments, the fifth processing strategy includes at least one of the following: a connection constraint strategy, that is, a constraint strategy that the control module must follow when accessing an access network node. Exemplarily, the connection constraint strategy includes: a first target cell list that the control module allows access or reselection; when the cell accessed by the control module does not belong to a cell in the first target cell list, re-initiate access to a cell in the first target cell list.
[0116] In some embodiments, the above S201 may be implemented as: receiving a processing strategy for processing an abnormal state of the wireless relay device sent by the second node.
[0117] It is understandable that the above processing strategy may be formulated by the second node according to the abnormal state of the wireless relay device, and the second node sends the above processing strategy to the first node. Exemplarily, the second node may be a management entity of the wireless relay device.
[0118] In S202, the first node sends a processing strategy to the wireless relay device. Correspondingly, the wireless relay device receives the processing strategy sent by the first node for processing the abnormal state of the wireless relay device.
[0119] It is understood that, based on the exception handling method provided in the embodiments of the present disclosure, the first node determines a processing strategy for handling an abnormal state of the wireless relay device and transmits the processing strategy to the wireless relay device; accordingly, the wireless relay device receives the processing strategy for handling an abnormal state of the wireless relay device transmitted by the first node. In this way, the wireless relay device can manage its own operating status in real time and, when an abnormal state occurs, can perform self-processing according to the processing strategy, thereby improving the control robustness and operating reliability of the wireless relay device and achieving stable and high-quality coverage for mobile terminals.
[0120] In some embodiments, after the above S202 , as shown in FIG5 , the exception handling method further includes the following S301 and S302 .
[0121] In S301 , the wireless relay device detects its own working status.
[0122] In S302 , when an abnormal state occurs in the wireless relay device, the wireless relay device executes a processing strategy.
[0123] It can be understood that based on the exception handling method provided in the embodiment of the present disclosure, the wireless relay device can manage its own working status in real time, and then when an abnormal state occurs, it can perform self-processing according to the processing strategy, which can improve the control robustness and working reliability of the wireless relay device to achieve stable and high-quality coverage of mobile terminals.
[0124] In some embodiments, as shown in FIG6 , the above exception handling method further includes the following S401 to S403 .
[0125] In S401 , the wireless relay device detects its own working status.
[0126] In S402 , when an abnormal state occurs in the wireless relay device, the wireless relay device generates an abnormal state report.
[0127] The abnormal status report includes at least one of the following: abnormality type, abnormality occurrence time (including the occurrence time of each abnormality type), abnormality value, and operation log of the wireless relay device.
[0128] In S403, the wireless relay device sends an abnormal status report to the first node. Correspondingly, the first node receives the abnormal status report sent by the wireless relay device.
[0129] In some embodiments, after the above S403, the exception handling method further includes: the first node sending an abnormal status report of the wireless relay device to the second node.
[0130] In some embodiments, the above-mentioned exception handling method further includes: when a connection abnormality is detected between the first node and the control module, the first node sends a status report of the connection abnormality between the first node and the control module to the second node.
[0131] It is understood that, based on the exception handling method provided in the embodiments of the present disclosure, the wireless relay device can manage its own operating status in real time and, when an abnormal state occurs, promptly send an abnormal state report to the first node to inform the first node. In this way, the first node can handle the abnormal state to ensure the operational reliability of the wireless relay device.
[0132] For ease of understanding, the exception handling method provided in the embodiment of the present disclosure is described below in the form of examples.
[0133] It should be noted that in the following examples, the first node is a wireless communication base station (hereinafter referred to as a base station), the wireless relay device is a RIS, the control module of the wireless relay device is a RIS-MT, the wireless signal relay module of the wireless relay device is a RIS-Fwd, and the second node is a RIS management entity. The RIS management entity can manage the RIS through the base station and is responsible for formulating exception handling policies for the RIS. The RIS-MT can communicate with the base station, receive control information from the base station, report RIS status information to the base station and the RIS management entity, and control the operation of the RIS-Fwd.
[0134] In the following examples, the application scenario where RIS is deployed within the coverage area of a base station is used as an example.
[0135] Example 1: Handling a connection anomaly between RIS-MT and RIS-Fwd.
[0136] Exemplarily, as shown in FIG7 , in Example 1, the above exception handling method can be implemented as the following Sa1 to Sa8 .
[0137] In Sa1, the RIS-MT accesses the base station.
[0138] In Sa2, the base station performs identity recognition on the access terminal (ie, RIS-MT), and identifies that the device type of the access terminal is a RIS device.
[0139] Exemplarily, the base station may identify the RIS device according to the core network subscription information of the RIS device; or, the base station may identify the RIS device in combination with capability information reported by the RIS-MT.
[0140] In Sa3, the base station sends the exception handling policy to RIS-MT.
[0141] The exception handling strategy is a first handling strategy for connection anomalies between the RIS-MT and the RIS-Fwd. Exemplarily, the first handling strategy includes one or more of the following: shutting down the RIS-Fwd; placing the RIS-Fwd in standby mode; and generating and reporting a first anomaly status report to the base station. The first anomaly status report includes the anomaly type, the occurrence time and / or duration of each anomaly type, and the first anomaly value.
[0142] The first abnormal value includes at least one of the following: a packet error rate or a packet loss rate, a range of an antenna reflectarray corresponding to a control codebook where configuration fails, a panel attitude adjustment feedback value of RIS-Fwd, a readback value of an antenna reflectarray control codebook of RIS-Fwd, and an identifier of at least part of an antenna reflectarray that is turned off.
[0143] It should be noted that various types of connection exceptions between the RIS-MT and the RIS-Fwd may be indicated in the first processing strategy, or may be pre-configured to the RIS, or may be agreed upon with the RIS in advance.
[0144] Illustratively, the connection abnormality between RIS-MT and RIS-Fwd includes at least one of the following abnormality types: the connection between RIS-MT and RIS-Fwd is interrupted; the packet error rate or packet loss rate between RIS-MT and RIS-Fwd is higher than a first preset threshold; the packet error rate / packet loss rate is higher than a preset threshold; RIS-MT's control over RIS-Fwd is abnormal.
[0145] RIS-MT's control anomalies over RIS-Fwd include at least one of the following: failure to configure the control codebook of at least part of the antenna reflectarray in RIS-Fwd; failure to adjust the panel attitude of RIS-Fwd or failure to adjust it properly; for example, failure to adjust the azimuth angle or failure to adjust it properly, or failure to adjust the tilt / pitch angle or failure to adjust it properly; failure to switch the RIS-Fwd on / off; failure to adjust the power of RIS-Fwd or failure to adjust it properly; failure to query the status of RIS-Fwd; failure to read back the control codebook of the antenna reflectarray in RIS-Fwd; and the read-back value of the control codebook of the antenna reflectarray in RIS-Fwd is inconsistent with the configured value.
[0146] It should be noted that the above-mentioned preset threshold may be configured in the first processing strategy; or, the above-mentioned preset threshold may be pre-configured to the RIS through other signaling.
[0147] In Sa4, the RIS-MT receives the RIS control information sent by the base station.
[0148] The RIS control information includes codebook adjustment instructions, power adjustment instructions, and switch state adjustment instructions for RIS-Fwd.
[0149] In Sa5, RIS-MT sends RIS-Fwd control information to RIS-Fwd.
[0150] At the same time, RIS-MT keeps monitoring RIS-Fwd.
[0151] In Sa6, RIS-MT determines whether an abnormality occurs between RIS-MT and RIS-Fwd.
[0152] Exemplarily, after RIS-MT sends RIS-Fwd control information to RIS-Fwd, if RIS-MT does not receive confirmation feedback information from RIS-Fwd, it is determined that the connection between RIS-MT and RIS-Fwd is disconnected.
[0153] Exemplarily, after RIS-MT sends RIS-Fwd control information, if the received codebook readback value is inconsistent with the configured value, it is confirmed that the connection between RIS-MT and RIS-Fwd is disconnected.
[0154] For example, after the panel posture of RIS-Fwd is adjusted, if the feedback adjustment angle received is inconsistent with the configured value, it is confirmed that the connection between RIS-MT and RIS-Fwd is disconnected.
[0155] In Sa7, when it is determined that an abnormality occurs between RIS-MT and RIS-Fwd, RIS-MT performs self-processing according to the first processing strategy.
[0156] For example, if it is detected that the connection between RIS-MT and RIS-Fwd is interrupted, an abnormal status report may be generated and reported to a network-side node (eg, a base station).
[0157] For example, if it is identified that the codebook readback value is inconsistent with the configured value, it may be possible to choose to turn off RIS-Fwd or put RIS-Fwd into standby mode.
[0158] For example, if it is identified that the panel posture of RIS-Fwd is not in place, you can choose to turn off RIS-Fwd or put RIS-Fwd on standby, or you can choose to generate an abnormal status report and report it to the network side node. The network side node decides whether to turn off RIS-Fwd or choose other ways to adjust the RIS beam (such as switching the control code book of the antenna reflection array of RIS-Fwd).
[0159] In Sa8, the RIS-MT generates a first abnormal status report and sends it to the base station.
[0160] Exemplarily, RIS-MT generates a first abnormality status report according to the identified abnormality type, the occurrence time and / or occurrence duration of each abnormality type, and the first abnormality value.
[0161] The first abnormal value includes at least one of the following: a packet error rate or a packet loss rate, a range of an antenna reflectarray corresponding to a control codebook where configuration fails, a panel attitude adjustment feedback value of RIS-Fwd, a readback value of an antenna reflectarray control codebook of RIS-Fwd, and an identifier of at least part of an antenna reflectarray that is turned off.
[0162] Example 2: Handling an abnormal connection between the base station and RIS-MT.
[0163] Exemplarily, as shown in FIG8 , in Example 2, the above exception handling method may be implemented as the following Sb1 to Sb12 .
[0164] In Sb1, RIS-MT accesses the base station.
[0165] In Sb2, the base station sends the terminal device identifier of the RIS to the management entity of the RIS. Correspondingly, the management entity of the RIS receives the terminal device identifier of the RIS sent by the base station.
[0166] In Sb3, the management entity of the RIS performs identity recognition on the access terminal (ie, RIS-MT), and identifies that the device type of the access terminal is a RIS device.
[0167] Illustratively, the RIS management entity may identify the RIS device based on core network subscription information; or, the RIS management entity may identify the RIS device based on capability information reported by the RIS-MT; or, the RIS management entity may identify the RIS device based on stored registration information.
[0168] In Sb4, the management entity of the RIS sends an exception handling policy to the base station.
[0169] In Sb5, the base station sends the exception handling policy to RIS-MT.
[0170] The exception handling strategy is a second handling strategy for connection anomalies between the base station and the RIS-MT. Exemplarily, the second handling strategy includes one or more of the following: a first constraint strategy that the RIS-MT must follow when accessing the base station; a second self-handling strategy of the RIS-MT; and the generation and reporting of a second exception status report by the RIS-MT. The second exception status report includes at least one of the following: the anomaly type, the occurrence time and / or duration of each anomaly type, a second anomaly value, and the RIS operation log.
[0171] Exemplarily, the second abnormal value includes at least one of the following: an abnormal measurement value of the beam arrival angle or beam arrival direction, the frequency of wireless link failure, the frequency of beam failure, the number or frequency of RIS status information transmission failures, the failure log, the reselection failure frequency, the identification of the resident cell, and the identification of the access cell.
[0172] In some embodiments, the first constraint strategy includes at least one of the following: a list of first target cells that RIS-MT is allowed to access or reselect; a priority of target cells that RIS-MT is allowed to access or reselect; a list of second target cells that RIS-Fwd allows relaying; the number of access failure retries for RIS-MT; and the access failure retry time interval for RIS-MT.
[0173] In some embodiments, the second self-processing strategy includes at least one of the following: RIS-MT shuts down at least part of the antenna reflect array in RIS-Fwd; RIS-MT adjusts RIS-Fwd to a standby state; RIS-MT reconnects to the network-side node and turns on RIS-Fwd; if the cell accessed by RIS-MT does not comply with the first constraint strategy, RIS-MT re-initiates access according to the target cell provided by the first constraint strategy; RIS-MT keeps the current working state and codebook of RIS-Fwd unchanged; RIS-MT switches the codebook of RIS-Fwd to a first preset codebook, where the first preset codebook is used to adjust the outgoing beam of RIS-Fwd to point to the target area; RIS-MT switches the codebook of RIS-MT to a second preset codebook, where the second preset codebook is used to adjust the outgoing beam coverage range of RIS-Fwd to increase it to a preset range.
[0174] The first preset codebook and the second preset codebook may be sent to the RIS together with the second processing strategy.
[0175] Exemplarily, the connection abnormality between the base station and RIS-MT includes at least one of the following abnormality types: the beam arrival angle or beam arrival direction measured by RIS-MT exceeds a first preset range, the beam arrival angle refers to the angle of the beam emitted by the base station when it reaches the antenna panel of RIS-Fwd, and the beam arrival direction refers to the direction of the beam emitted by the base station when it reaches the antenna panel of RIS-Fwd; the wireless link between the base station and RIS-MT is abnormal; RIS-MT fails to perform cell reselection; RIS-MT does not reside in a high-priority cell or a preset target cell after performing cell reselection; RIS-MT fails to successfully access the access network node; the number of RIS-MT access failures is greater than or equal to a second preset threshold; RIS-MT does not access a high-priority cell or a preset target cell.
[0176] Exemplarily, the radio link abnormality between the base station and the RIS-MT includes at least one of the following: radio link failure; the frequency of radio link failure exceeds a third preset threshold; beam failure; the frequency of beam failure exceeds a fourth preset threshold; the base station fails to send control information to the RIS-MT; the RIS-MT fails to send status information to the base station.
[0177] It should be noted that the above-mentioned various exception types may be indicated in the second processing strategy; or, the above-mentioned various exception types may be pre-configured to the RIS; or, the above-mentioned various exception types may be pre-agreed with the RIS.
[0178] The preset threshold may be configured in the second processing strategy; or, the preset threshold may be pre-configured to the RIS through other signaling.
[0179] In Sb6, the RIS-MT receives the RIS control information sent by the base station.
[0180] The RIS control information includes codebook adjustment instructions, power adjustment instructions, and switch state adjustment instructions for RIS-Fwd.
[0181] In Sb7, RIS-MT sends RIS-Fwd control information to RIS-Fwd.
[0182] At the same time, RIS-MT keeps monitoring RIS-Fwd.
[0183] In Sb8, the RIS-MT and the base station respectively detect that the communication link between the RIS-MT and the base station is abnormal.
[0184] It is understandable that the RIS-MT and the base station can respectively monitor the communication link therebetween and determine whether the communication link connection between the RIS-MT and the base station is abnormal.
[0185] Exemplarily, in the case of a wireless link failure, it is determined that the connection between the RIS-MT and the base station is abnormal.
[0186] Exemplarily, in the case of beam failure, it is determined that the connection between the RIS-MT and the base station is abnormal.
[0187] Exemplarily, when the cell accessed by the RIS-MT is not a high-priority cell or a preset target cell, it is determined that the connection between the RIS-MT and the base station is abnormal.
[0188] In Sb9, when the base station detects a communication link failure between the RIS-MT and the base station, it generates a status report of abnormal connection between the RIS-MT and the base station and sends it to the management entity of the RIS.
[0189] In Sb10, when the RIS-MT detects a communication link failure between the RIS-MT and the base station, the RIS-MT performs self-processing according to the second processing strategy.
[0190] Exemplarily, if a radio link failure is detected and the target cell provided by the first restriction strategy cannot be accessed, RIS-MT is disabled, or the codebook of RIS-Fwd is switched to the first preset codebook or the second preset codebook.
[0191] For example, if it is detected that the cell accessed by the RIS-MT does not comply with the first restriction policy, access is re-initiated according to the target cell provided by the first restriction policy.
[0192] For example, if the beam fails, the number of failures, the time of occurrence, the beam measurement value, etc. are recorded to generate an abnormal status report.
[0193] It should be noted that the embodiment of the present disclosure does not limit the execution order of the above-mentioned Sb9 and Sb10. For example, Sb9 may be executed first and then Sb10; or Sb10 may be executed first and then Sb9; or Sb9 and Sb10 may be executed simultaneously.
[0194] In Sb11, after RIS-MT successfully reconnects to the base station, it uploads the abnormal status report of RIS.
[0195] In Sb12, the base station forwards the abnormal status report of the RIS to the management entity of the RIS.
[0196] Example 3: Exception handling method for abnormal connection between the management entity of RIS and RIS-MT.
[0197] It is understandable that the management entity of RIS is usually connected to RIS through the base station. When the connection between the management entity of RIS and RIS is abnormal, it is likely that there is a problem with the air interface connection between the base station and RIS. Therefore, the exception handling method for the abnormal connection between the management entity of RIS and RIS-MT in Example 3 can refer to the exception handling method for the abnormal connection between the base station and RIS-MT in the above Example 2.
[0198] Example 4: Exception handling method for RIS-MT exception or RIS-Fwd exception.
[0199] Exemplarily, as shown in FIG9 , in Example 4, the above exception handling method may be implemented as follows Sc1 to Sc8 .
[0200] In Sc1, the RIS-MT accesses the base station.
[0201] In Sc2, the base station performs identity recognition on the access terminal (ie, RIS-MT), and identifies that the device type of the access terminal is a RIS device.
[0202] Exemplarily, the base station may identify the RIS device according to the core network subscription information of the RIS device; or, the base station may identify the RIS device in combination with capability information reported by the RIS-MT.
[0203] In Sc3, the base station sends the exception handling policy to RIS-MT.
[0204] The exception handling strategy is a strategy for handling RIS-MT exceptions and / or a third strategy for handling RIS-Fwd exceptions. Exemplarily, the third strategy includes one or more of the following: a second constraint strategy that RIS-MT or RIS-Fwd must follow during runtime; a third self-handling strategy of RIS-MT; and generation and reporting of a third exception status report by RIS-MT.
[0205] In some embodiments, the second constraint policy includes at least one of the following: the on-time, off-time and standby time of RIS-Fwd follow a preset schedule; the on-time, off-time, standby time and connection time of RIS-MT follow a preset schedule.
[0206] In some embodiments, the third self-processing strategy includes at least one of the following: the RIS-MT turns off at least part of the antenna reflection array in the RIS-Fwd, for example, the RIS-MT turns off the RIS-Fwd; or the RIS-MT turns off part of the antenna array in the RIS-Fwd; the RIS-MT adjusts the RIS-Fwd to a standby state.
[0207] In some embodiments, the third abnormal status report includes at least one of the following: abnormality type, abnormality occurrence time (including the occurrence time of each abnormality type), a third abnormality value, and an operation log of the wireless relay device.
[0208] The third abnormal value includes at least one of the following: voltage, power consumption, charging power, remaining power or remaining working time, an identifier of an antenna reflection array with abnormal voltage, and an identifier of a turned-off antenna reflection array.
[0209] Exemplarily, RIS-MT abnormalities include at least one of the following: the standby voltage or standby power consumption exceeds the fifth preset threshold; the operating voltage or operating power consumption exceeds the sixth preset threshold; the charging power is lower than the seventh preset threshold; the charging power is higher than the eighth preset threshold; the remaining power or remaining operating time is lower than the ninth preset threshold; one or more of the RIS-MT power-on time, power-off time, idle operation time and connected operation time do not comply with the preset schedule.
[0210] In some embodiments, the RIS-Fwd abnormality includes at least one of the following: the standby voltage or standby power consumption exceeds the tenth preset threshold; the operating voltage or operating power consumption exceeds the eleventh preset threshold; the operating voltage or standby voltage of at least some antenna units in the antenna reflection array is abnormal; the charging power is lower than the twelfth preset threshold; the charging power is higher than the thirteenth preset threshold; the remaining power or remaining working time is lower than the fourteenth preset threshold; one or more of the RIS-Fwd power-on time, power-off time and standby operation time do not comply with the preset schedule.
[0211] It should be noted that the preset values such as the preset threshold and the preset timetable may be configured in the third processing strategy; or, the preset values such as the preset threshold and the preset timetable may be pre-configured to the RIS through other signaling.
[0212] In Sc4, the RIS-MT receives the RIS control information sent by the base station.
[0213] The RIS control information includes codebook adjustment instructions, power adjustment instructions, and switch state adjustment instructions for RIS-Fwd.
[0214] In Sc5, RIS-MT sends RIS-Fwd control information to RIS-Fwd.
[0215] At the same time, RIS-MT keeps monitoring RIS-Fwd.
[0216] In Sc6, during operation, RIS-Fwd sends a RIS-Fwd status report to RIS-MT.
[0217] The status report of the RIS-Fwd includes at least one of the following: power consumption, operating voltage, and standby voltage of the RIS-Fwd.
[0218] Exemplarily, the RIS-Fwd periodically sends a RIS-Fwd status report to the RIS-MT.
[0219] Exemplarily, in response to the query instruction of the RIS-MT, the RIS-Fwd sends a RIS-Fwd status report to the RIS-MT.
[0220] Exemplarily, in response to a preset event, the RIS-Fwd sends a RIS-Fwd status report to the RIS-MT.
[0221] It is understandable that RIS-MT can detect whether the operation of RIS-Fwd is abnormal based on the status report of RIS-Fwd.
[0222] In Sc7, when RIS-MT detects an operational abnormality of itself or RIS-Fwd, RIS-MT performs self-processing according to the third processing strategy.
[0223] For example, if it is detected that the voltage or power consumption of the RIS-Fwd exceeds a preset range, the RIS-Fwd may be turned off or put into standby mode.
[0224] For example, if it is detected that the operating voltage or standby voltage of some antenna elements or antenna units of the antenna reflect array is abnormal, the abnormal antenna reflect array may be shut down.
[0225] In Sc8, the RIS-MT generates and reports an abnormal status report to the base station.
[0226] Exemplarily, the RIS-MT records the identified abnormality type, the occurrence time and / or occurrence duration of each abnormality type, and the third abnormality value, generates an abnormality status report, and sends it to the base station.
[0227] Exemplarily, the abnormal value includes at least one of the following: voltage, power consumption, charging power, remaining power or remaining working time, an identifier of an antenna reflection array with abnormal voltage, and an identifier of a turned-off antenna reflection array.
[0228] The above mainly introduces the solution of the embodiment of the present disclosure from the perspective of method. It is understandable that, in order to realize the above functions, the communication device includes at least one of the hardware structure and software modules corresponding to the execution of each function. It should be easily appreciated by those skilled in the art that, in combination with the units and algorithm steps of each example described in the embodiment disclosed herein, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the embodiment of the present disclosure.
[0229] The embodiments of the present disclosure can divide the functional modules of the communication device according to the above-mentioned method embodiments. For example, each functional module can be divided corresponding to each function, or two or more functions can be integrated into one functional module. The above-mentioned integrated modules can be implemented in the form of hardware or software. It should be noted that the division of modules in the embodiments of the present disclosure is schematic and is only a logical functional division. In actual implementation, there may be other division methods. The following is an example of dividing each functional module corresponding to each function.
[0230] Figure 10 is a schematic diagram of the structure of a communication device according to an embodiment of the present disclosure, which is applied to a wireless relay device and can execute the exception handling method provided in the above method embodiment. As shown in Figure 10, the communication device 600 includes: a communication module 601. In other embodiments, the communication device 600 also includes a detection module 602 and a processing module 603.
[0231] The communication module 601 is configured to receive a processing strategy for processing an abnormal state of a wireless relay device sent by a first node.
