Description

Technical Field

[0001] This invention relates to the field of wireless communication, and in particular to a control method, system and related equipment for a wireless relay device. Background Technology

[0002] Repeaters are common devices used in wireless communication systems to extend coverage, with applications spanning from 2G to 5G. Currently, the primary function of radio frequency repeaters is to amplify signals without performing any signal analysis. Compared to base stations, wireless repeaters have a simpler structure, consisting of components or modules such as antennas, RF duplexers, low-noise amplifiers, mixers, electrically adjustable attenuators, filters, and power amplifiers, including both uplink and downlink amplification links. Because the function of a wireless repeater is solely to amplify signals, it amplifies noise and interference signals along with the useful signal.

[0003] As a technical means of coverage compensation, besides Layer 1 (L1) devices like repeaters, some coverage extension devices have been defined in the evolution and practice of wireless network standards. These include relay devices in the 4G era and Integrated Access Backhaul (IAB) devices in the 5G era. These devices are characterized by possessing all Layer 1 to Layer 3 wireless protocol stacks and being opaque to the user interface (UE). That is, from the UE's perspective, a 4G relay or a 5G IAB is a single base station; while from the base station's perspective, a 4G relay or an IAB is a single terminal. Therefore, base station data transmission and reception are performed by scheduling the relay or IAB.

[0004] The 5G standard Rel-18 will introduce a new wireless forwarding device technology—the Network Controlled Repeater (NCR). The NCR consists of two parts: the NCR-RU (Radio Unit) part, which forwards and amplifies UE signaling and data signals, functions similarly to existing repeaters; and the NCR-MT (Mobile Terminal) part, which performs some UE-like functions and is responsible for signaling interaction with the base station.

[0026] In some embodiments, the control method further includes: in the second state, the wireless forwarding device transitions from the second state to the first state when it determines that it has lost synchronization with the base station.

[0027] In some embodiments, if a wireless forwarding device in the second state fails to correctly decode the base station's broadcast messages and Master System Information Block (MIB) messages in a consecutive preset number of downlink wireless frames, it determines that the wireless forwarding device has lost synchronization with the base station.

[0028] In some embodiments, the preset information is a broadcast of the wireless standard of the cell where the wireless relay device is camped, or a wake-up indication message.

[0029] In some embodiments, the wireless forwarding device performs discontinuous listening to the information sent by the base station according to the configuration information, and switches to the second state when a preset information is detected, including: the wireless forwarding device performs discontinuous listening to the second broadcast message sent by the base station on a radio frame that meets the preset conditions according to the configuration information; when the signal strength of the detected second broadcast message is greater than a preset threshold and the second broadcast message indicates that the cell where the wireless forwarding device is located can restore the connection, the wireless forwarding device switches to the second state.

[0030] In some embodiments, a radio frame that meets a preset condition is determined based on a pre-configured number and offset of listenable frames, a period of discontinuous listening, the identifier of the radio forwarding device, and the identifier of the radio frame.

[0031] In some embodiments, wireless frames that meet preset conditions are determined according to the following formula:

[0032] (SFN+offset)modT=(T / N)*(IDmodN)

[0033] Wherein, SFN is the identifier of the radio frame; offset is the preset offset of the frames that can be monitored; T is the preset period of discontinuous monitoring; N is the preset number of frames that can be monitored; and ID is the identifier of the radio forwarding device, which is sent to the base station by the radio forwarding device through random access or pre-configuration.

[0034] In some embodiments, the control method further includes: in a first state, if the duration of discontinuous listening by the wireless forwarding device exceeds a preset waiting time, attempting to read broadcast messages to determine whether the base station has resumed operation; if it is determined that the base station has not resumed operation and the wireless forwarding device is configured with a cell selection indication, the wireless forwarding device selects a different cell than the one accessed last time and attempts to access it.

[0040] The receiving module is configured to receive signaling sent by the base station in a second state, wherein the signaling includes at least one of a return indication, a forwarding indication, or a cell selection indication;

[0041] The signal forwarding and amplification module is configured to forward or amplify the signal between the base station and the terminal in a second state; in a first state, if the configuration information for discontinuous monitoring is obtained in advance and indicates that the signal forwarding and amplification function is maintained, the received signal is forwarded or amplified; and if a forwarding instruction is obtained in advance, the terminal signal within the coverage area of ​​the wireless forwarding device is forwarded according to the forwarding instruction using the corresponding forwarding method.

[0045] In some embodiments, the wireless repeater is a smart repeater.

[0046] According to a third aspect of some embodiments of the present invention, a control system for a wireless forwarding device is provided, comprising: the aforementioned wireless forwarding device; and a base station.

[0049] Some embodiments of the above invention have the following advantages or beneficial effects. Based on the control plane connection relationship between the base station and the wireless forwarding device on the access link, the embodiments of the present invention set two states for the wireless forwarding device. When the control plane connection is disconnected (i.e., in the first state), the wireless forwarding device can perform discontinuous listening to save energy. When the conditions for restoring normal operation are met, it can quickly restore the connection and promptly switch to the second state to continue normal signal forwarding and amplification, thereby reducing service interruptions, ensuring the user experience under coverage, and saving energy for the wireless forwarding device. Furthermore, it avoids situations where intelligent repeaters access other cells due to uncontrolled behavior of the wireless forwarding device when the base station is shut down, ensuring network control over the wireless forwarding device and guaranteeing the performance of the terminals covered by the wireless forwarding device.

[0066] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0067] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of the invention.

[0068] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0069] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0070] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0071] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0072] Figure 1A An exemplary schematic diagram of an RF repeater is shown. (e.g.) Figure 1A As shown, an RF repeater consists of components or modules such as an antenna, RF duplexer, low-noise amplifier, mixer, electrically adjustable attenuator, filter, and power amplifier, including uplink and downlink amplification links.

[0073] Figure 1B An exemplary schematic diagram of an RF repeater's operating scenario is shown. For example... Figure 1B As shown, the RF repeater is within the coverage area of ​​the base station gNB, and the terminal UE is within the coverage area of ​​the RF repeater. The RF repeater forwards and amplifies signals between the gNB and the UE.

[0074] Figure 1C An exemplary diagram illustrates the structure of a smart repeater (NCR) and its connection to the UE and gNB. For example... Figure 1C As shown, the UE communicates with the NCR-RU via the Uu interface; the gNB communicates with the NCR-RU and the NCR-MT via the Uu interface. The gNB transmits uplink and downlink control signaling and data of the UE with the NCR-RU, and transmits control signaling of the NCR with the NCR-MT.

[0075] Figure 1D An exemplary schematic diagram of a smart repeater's working scenario is shown. For example... Figure 1DAs shown, the intelligent repeater RF repeater is within the coverage area of ​​the base station gNB, and the terminal UE is within the coverage area of ​​the intelligent repeater RF repeater. The intelligent repeater RF repeater forwards and amplifies signals between the gNB and the UE. Compared to a traditional radio frequency repeater, the intelligent repeater can support data transmission based on beamforming.

[0076] In 5G networks, the increased bandwidth and number of antennas lead to increased power consumption in 5G base stations, necessitating the further application of energy-saving technologies. In both standards and practical applications, deactivation is often used to conserve power in 5G base stations. For connected terminals, handover is typically employed to prevent service loss due to signal interruption.

[0077] Traditional repeaters operate continuously after power-on to perform tasks such as network synchronization, signal forwarding, and amplification. Even when the base station loses signal, the repeater typically continues to operate, although its power consumption remains relatively high.

[0078] Furthermore, if the repeater is constantly in a listening state, its base station power consumption is relatively high. Therefore, from the perspective of reducing power consumption, there is also a need for a way to notify the repeater to restore the connection and synchronization.

[0079] Furthermore, when the macro station is shut down, the repeater's behavior is undefined, which may lead to different and uncontrolled states for the repeater depending on the implementation. Since the repeater also supports some UE-related functions, it typically will not switch to another cell when the macro station is shut down, potentially resulting in no service; if it returns to an idle state, it may reselect to another cell, etc. Without defining these states, the repeater's state may be beyond network control.

[0080] Therefore, current protocols cannot meet the design requirements of intelligent repeaters. Furthermore, given the still unclear protocol stack architecture of repeaters, new standardized methods are needed to enhance functionality and meet the needs of network deployment and optimization.

[0081] Based on this, one of the technical problems to be solved by the embodiments of the present invention is: how to reduce the energy consumption of repeaters and meet the design requirements of intelligent repeaters.

[0082] Embodiments of the present invention configure two states for the wireless forwarding device. In the first state, the control plane connection on the access link between the wireless forwarding device and the base station is disconnected; in the second state, the wireless forwarding device maintains the control plane connection on the access link with the base station and forwards or amplifies the signal between the base station and the terminal.

[0083] When a radio forwarding device in the second state discovers that it can no longer provide services to the base station, it transitions from the second state to the first state. This transition can be triggered by the base station or by the radio forwarding device itself.

[0084] The following is for reference. Figure 2A An embodiment of the control method for the wireless forwarding device of the present invention is described. In this embodiment, the base station instructs the wireless forwarding device to switch to a first state via signaling.

[0085] Figure 2A A flowchart illustrating a control method for a wireless forwarding device according to some embodiments of the present invention is shown. Figure 2A As shown, the control method of the wireless forwarding device in this embodiment includes steps S202 to S216.

[0086] Steps S202 to S206 describe the operation of the wireless forwarding device in the second state.

[0087] In step S202, the wireless forwarding device forwards or amplifies the signal between the base station and the terminal. That is, the wireless forwarding device is in normal working condition.

[0088] In some embodiments, the wireless repeater is a smart repeater.

[0089] In step S204, the base station sends signaling to the wireless forwarding device.

[0090] For example, the base station sends this signaling when the base station is turned off or when the cell to which the wireless forwarding device is connected is turned off.

[0091] The signaling sent by the base station is used to instruct the radio forwarding device to return to the first state. In addition, the signaling may include other content to indicate some configuration information after the base station transitions to the first state. In some embodiments, the signaling includes at least one of a return indication, a forwarding indication, and a cell selection indication.

[0092] In some embodiments, the signaling is a DCI (Downlink Control Information) indication, a MAC CE (MAC: Media Access Control, CE: Control Element) message, or an RRC (Radio Resource Control) message.

[0093] In some embodiments, the signaling includes, but is not limited to, one or more of the following:

[0094] - Return indication information, for example, represented by 1 bit, indicating that the forwarding device has returned from the second state to the first state;

[0095] - Downlink forwarding stop indication, for example, represented by 1 bit, is used to indicate whether the wireless forwarding device should continue downlink forwarding after transitioning to the first state;

[0096] In some embodiments, when the signaling carries a downlink forwarding stop indication, the radio forwarding device does not forward the received downlink signal; when the signaling carries a downlink forwarding stop indication but does not carry an uplink forwarding stop indication, the radio forwarding device does not forward the received uplink signal; when the signaling does not carry a downlink forwarding stop indication, the radio forwarding device forwards the received downlink signal.

[0097] -Uplink forwarding stop indication, for example, represented by 1 bit, is used to indicate whether the wireless forwarding device should continue uplink forwarding after transitioning to the first state;

[0098] In some embodiments, if the signaling carries an uplink forwarding stop indication, the radio forwarding device does not forward the received uplink signal; if the signaling does not carry an uplink forwarding stop indication, the radio forwarding device forwards the received uplink signal.

[0099] - Cell selection indication, for example, represented by 1 bit, is used to indicate that when the radio forwarding device transitions from the first state to the second state, it accesses a different cell than the one it accessed last time; otherwise, it remains in the cell it accessed last time.

[0100] - The waiting time indication is a preset time with preset granularity. It is used to instruct the wireless forwarding device to attempt to read broadcast messages to determine whether the base station has resumed operation if the duration of discontinuous listening exceeds the preset time. Before the timeout, the device will continue to monitor the information sent by the base station using discontinuous listening.

[0101] In step S206, when a signaling message is received from the base station and the signaling message includes a return indication, the wireless forwarding device transitions from the second state to the first state.

[0102] Steps S208 to S216 describe the operation of the wireless forwarding device in the second state.

[0103] In step S208, if the pre-acquired configuration information for discontinuous monitoring indicates that the signal forwarding and amplification functions are maintained, the wireless forwarding device forwards or amplifies the received signal.

[0104] In some embodiments, this configuration information is sent by the base station for discontinuous monitoring.

[0105] In some embodiments, the wireless forwarding device receives configuration information via broadcast messages or preset signaling in either a first state or a second state. If the wireless forwarding device obtains the configuration information in the second state, it saves the configuration information but does not perform the listening information operation in the second state.

[0106] In some embodiments, the configuration information includes, but is not limited to, one or more of the following:

[0107] - The period of non-continuous listening, for example, represented by an integer value;

[0108] - The number and offset of frames that can be monitored, for example, including one or more sets, each set containing multiple integers, the length of which represents the number of wireless frames that can be monitored within a non-contiguous monitoring period, and the values ​​in the set representing the offset of the frames that can be monitored.

[0109] - Signal forwarding and amplification function off indication, such as an enumeration value or a Boolean value, when this indication is configured, instructs the wireless forwarding device not to forward and amplify the signal between the base station and the terminal in the first state.

[0110] In step S210, if the signaling includes a cell selection indication, the radio forwarding device accesses the corresponding cell according to the cell selection indication.

[0111] In some embodiments, when the signaling carries a cell selection indication, the radio forwarding device accesses a different cell than the one it accessed last time in a first state; when the signaling does not carry a cell selection indication, the radio forwarding device remains in the cell it accessed last time.

[0112] Thus, the wireless relay device can determine the home cell based on the instructions from the base station.

[0113] In step S212, the wireless forwarding device, having obtained a forwarding instruction in advance, forwards the terminal signals within its coverage area using the corresponding forwarding method.

[0114] In some embodiments, the forwarding instruction includes an instruction for at least one of an uplink forwarding mode or a downlink forwarding mode, and the content of the instruction includes, for example, whether to stop forwarding in the corresponding direction.

[0115] Forwarding instructions can be sent via signaling, determined by an algorithm, or pre-configured.

[0116] In step S214, the wireless forwarding device performs discontinuous listening to the information sent by the base station according to the configuration information.

[0117] In some embodiments, discontinuous monitoring is periodic monitoring. Other discontinuous monitoring methods may be used as needed, which will not be elaborated here.

[0118] In step S216, the wireless relay device switches to the second state after detecting preset information.

[0119] Preset information is used to indicate that a base station or a cell of a base station has resumed normal operation. In some embodiments, the preset information is a broadcast of the radio standard of the cell where the radio relay device is camped, or a wake-up indication message.

[0120] The above embodiments, based on the control plane connection relationship between the base station and the wireless forwarding device on the access link, set two states for the wireless forwarding device. When the control plane connection is disconnected (i.e., in the first state), the wireless forwarding device can perform discontinuous listening to save energy. When the conditions for restoring normal operation are met, it can quickly restore the connection and promptly switch to the second state to continue normal signal forwarding and amplification, thereby reducing service interruptions, ensuring user experience, and saving energy for the wireless forwarding device. Furthermore, it avoids situations where intelligent repeaters, when the base station is shut down, may access other cells due to uncontrolled behavior of the wireless forwarding device, ensuring network control over the wireless forwarding device and guaranteeing the performance of the terminals covered by the wireless forwarding device.

[0121] The following is for reference. Figure 2B An embodiment of the control method for the wireless repeater of the present invention is described. In this embodiment, the process of transitioning to a first state is triggered automatically by the wireless repeater.

[0122] Figure 2B A flowchart illustrating a control method for a wireless forwarding device according to other embodiments of the present invention is shown. For example... Figure 2B As shown, the control method of the wireless forwarding device in this embodiment includes steps S222 to S224.

[0123] In step S222, in the second state, the wireless forwarding device determines that it has lost synchronization with the base station.

[0124] In some embodiments, if a wireless forwarding device in the second state fails to correctly decode the base station's broadcast messages and MIB (Master Information Block) messages in a consecutive preset number of downlink wireless frames, it determines that the wireless forwarding device has lost synchronization with the base station.

[0125] In step S224, the wireless forwarding device transitions from the second state to the first state.

[0126] Therefore, when the first base station is unable to notify the wireless forwarding device to enter the first state through control signaling due to abnormal reasons such as power failure, the wireless forwarding device can automatically switch states based on the judgment result, thus achieving the purpose of energy saving.

[0127] The following is for reference. Figure 3 An embodiment of the discontinuous monitoring method of the wireless forwarding device of the present invention in a first state is described.

[0128] Figure 3 A flowchart illustrating a discontinuous monitoring method according to some embodiments of the present invention is shown. Figure 3 As shown, the discontinuous monitoring method of this embodiment includes steps S302 to S306.

[0129] In step S302, the wireless forwarding device, based on the configuration information, performs discontinuous listening to the second broadcast message sent by the base station on a wireless frame that meets preset conditions.

[0130] In some embodiments, a radio frame that meets a preset condition is determined based on a pre-configured number and offset of listenable frames, a period of discontinuous listening, the identifier of the radio forwarding device, and the identifier of the radio frame.

[0131] In some embodiments, a wireless frame that meets a preset condition is determined according to formula (1):

[0132] (SFN+offset)modT=(T / N)*(ID mod N) (1)

[0133] Wherein, SFN is the identifier of the radio frame; offset is the preset offset of the frames that can be monitored; T is the preset period of discontinuous monitoring; N is the preset number of frames that can be monitored; and ID is the identifier of the radio forwarding device, which is sent to the base station by the radio forwarding device through random access or pre-configuration.

[0134] In step S304, the base station sends a second broadcast message after resuming operation.

[0135] In some embodiments, the second broadcast message includes, but is not limited to, one or more of the following:

[0136] - A forwarding device access indication, for example, 1 bit, is used when the second broadcast message carries this indication to indicate that the forwarding device can access the base station's cell;

[0137] - Dedicated resources accessed by forwarding devices, such as configuration information related to PRACH (Physical Random Access Channel);

[0138] - The signal quality threshold that can be accessed, for example, an integer value, is used to determine the minimum signal strength or the lowest signal quality value that the forwarding device can access.

[0139] In step S306, if the signal strength of the second broadcast message being monitored is greater than a preset threshold, and the second broadcast message indicates that the cell where the wireless forwarding device is located can restore the connection, the wireless forwarding device switches to the second state.

[0140] Through the above embodiments, the wireless forwarding device can promptly switch to the second state when it determines that the cell has returned to normal, so as to perform normal operation.

[0141] Figure 4 A flowchart illustrating a discontinuous monitoring method according to other embodiments of the present invention is shown. For example... Figure 4 As shown, the discontinuous monitoring method of this embodiment is executed in the first state, including steps S402 to S408.

[0142] In step S402, it is determined whether the duration of discontinuous listening exceeds a preset waiting time. If it does not exceed the preset time, proceed to step S404; if it does exceed the preset time, proceed to step S406.

[0143] In step S404, the wireless relay device performs discontinuous listening. The listening method can be referred to the foregoing embodiments, and will not be repeated here.

[0144] In step S406, an attempt is made to read broadcast messages to determine whether the base station has resumed operation.

[0145] In step S408, if it is determined that the base station has not resumed operation and the wireless forwarding device is configured with a cell selection indicator, the wireless forwarding device selects a different cell than the one it accessed last time and attempts to access it.

[0146] Therefore, even if the current base station is not working, it is possible to try to access other cells, thus improving the resource utilization of wireless forwarding equipment.

[0147] Figure 5 and Figure 6 Two exemplary application examples of the present invention are described exemplarily.

[0148] Figure 5 A flowchart illustrating a control method for an intelligent repeater according to some embodiments of the present invention is shown. Figure 5 As shown, the control method of this embodiment includes steps S502 to S514.

[0149] In step S502, the base station gNB sends out configuration information for discontinuous listening via SIB1 (System Information Block 1), including:

[0150] - The period T for non-continuous listening is 1280ms;

[0151] - Number of frames N that can be monitored and offset Offset: The number of frames that can be monitored is 4, and the offset is 0;

[0152] - Signal forwarding and amplification function off indicator: Yes.

[0153] In step S504, the smart repeater SP saves the contents of the SIB1 message.

[0154] In step S506, the SP synchronizes with the base station through MIB messages.

[0155] In step S508, in the connected state (i.e., the second state), after the gNB is powered off, the SP finds that it cannot detect the signal of the base station gNB after 2 minutes, determines that the SP has lost synchronization, and enters the idle state (i.e., the first state).

[0156] In step S510, SP disables the signal forwarding and amplification functions for the terminals under its coverage according to the signal forwarding and amplification function shutdown instruction.

[0157] In step S512, the SP determines the frame to be monitored based on the received MIB / SIB1 radio frame number. The SFN of the frame that meets the condition must satisfy the formula: MIB / SIB1 information, (SFN)mod 1280=(1280 / 4)*(3407mod 4), where the SP's identifier is 3407.

[0158] In step S514, when the SP hears a broadcast message sent by the gNB, and the signal strength of the broadcast message is greater than a preset threshold, and the SP indicates that the cell where the SP is located can restore the connection, the SP switches to the second state.

[0159] Through the above embodiments, the base station gNB can notify the smart repeater to switch to the first state through broadcast messages, and the smart repeater can also perform discontinuous listening in the first state.

[0160] Figure 6 A flowchart illustrating a control method for an intelligent repeater according to other embodiments of the present invention is shown. For example... Figure 6 As shown, the control method of this embodiment includes steps S602 to S612.

[0161] In step S602, if the base station gNB triggers a temporary shutdown due to energy saving reasons, the gNB will notify the smart repeater SP, which is in the connected state (i.e., the second state), to return to the idle state (i.e., the first state) via RRC message control signaling. The control signaling includes:

[0162] - Returns indication message: Yes;

[0163] - Downlink forwarding stop indication: Yes;

[0164] - Cell selection indicator: Yes;

[0165] - Waiting time indicator: 10 minutes.

[0166] In step S604, after receiving the control signaling sent by the gNB, the SP returns from the connected state to the idle state, and determines the forwarding mode as no longer forwarding downlink signals to terminals within its coverage area and forwarding uplink signals to the gNB according to the uplink and / or downlink forwarding stop indication.

[0167] In step S606, since the control signaling carries a cell selection indication, the SP determines not to select a new cell to re-access.

[0168] In step S608, SP determines the frame to be monitored based on the received MIB / SIB1 radio frame number. The SFN of the frame that meets the condition must satisfy the formula: (SFN)mod 1280=(1280 / 4)*(3407mod 4).

[0169] In step S610, 5 minutes after the SP starts listening, the base gNB resumes normal operation and sends the following information in a broadcast message:

[0170] - Forwarding device access indication: Yes;

[0171] - Dedicated resources accessed by forwarding devices: PRACH-related configuration information;

[0172] -Accessible signal quality threshold: -120dBm.

[0173] In step S612, 5 minutes after the SP starts listening, the SP detects that the SS-RSRP signal strength of the gNB is -110dB, which meets the signal quality threshold for access, and the waiting time indication information has not expired. Therefore, the SP reconnects to the gNB and enters the connection state.

[0174] Through the above embodiments, when the base station gNB instructs the smart repeater SP to return to the idle state via an RRC message due to energy-saving operation, the smart repeater in the idle state can, according to the instruction, not forward wireless signals from other base stations to terminals within its coverage area.
