[0002] Indoor distribution system (abbreviated as indoor distribution system) is a solution for indoor user groups to improve the mobile communication environment inside buildings. It mainly distributes the signal of mobile base station evenly in every corner of the room, thereby ensuring that the indoor area has ideal signal coverage.

[0003] 5G (5th Generation Mobile Communication Technology) indoor distribution systems employ 4-antenna pRRUs (Pico Remote Radio Units), achieving a cell bandwidth of 100MHz, and utilize extensive pRRU cell merging for coverage. Compared to 4G (4th Generation Mobile Communication Technology) base stations, 5G base stations have higher requirements for both hardware and software capabilities, but correspondingly, their energy consumption is also higher.

[0034] 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, not all, of the embodiments of the present invention. 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.

[0035] Reference Figure 1 The flowchart illustrates an embodiment of an energy-saving control method according to the present invention. The method can be applied to baseband equipment in an indoor distribution system, which also includes remote equipment. The method may include:

[0036] Step 101: Upon receiving an uplink signal reported by the first remote device and / or the second remote device, determine the target second remote device among the second remote devices; wherein, the first remote device refers to a remote device whose uplink channel and downlink channel remain in an open state; the second remote device refers to a remote device whose uplink channel remains in an open state, and whose downlink channel changes its open or closed state according to an instruction.

[0037] Step 102: Send a wake-up command to the target second remote device to open the downlink channel of the target second remote device.

[0038] This invention provides an energy-saving control method applicable to indoor distribution systems, specifically 5G indoor distribution systems (hereinafter referred to as 5G indoor distribution systems). A 5G indoor distribution system may include a three-tier architecture: baseband equipment, remote equipment, and a RHUB (remote radio unit hub). The baseband equipment refers to the BBU (baseband unit), and the remote equipment refers to the pRRU. (See reference...) Figure 2 This diagram illustrates the structure of a 5G indoor distribution system. One BBU can connect to one or more RHUBs (RHUBs). Figure 2(Only a scenario with one RHUB is shown in the diagram). One RHUB can connect to multiple pRRUs. The working principle of the 5G indoor distribution system is as follows: The BBU sends downlink signals to the RHUB. The RHUB and pRRUs are connected via network cables. The RHUB distributes the downlink signals to each pRRU. Each pRRU processes the downlink signals into radio frequency signals and then transmits the radio frequency signals indoors through transmission equipment such as radio frequency feeders, combiners / splitters, and antennas. The UEs indoors send feedback signals to the pRRUs. Each pRRU then sends its feedback signals to the RHUB. The RHUB aggregates the feedback signals and then transmits them to the BBU. It should be noted that this embodiment of the invention does not limit the number of the first remote devices or the number of the second remote devices. Figure 2 Take a first remote device as an example.

[0039] This invention classifies remote devices in a 5G indoor distributed antenna system (DAS) into first remote devices and second remote devices. The first remote device refers to a remote device whose uplink and downlink channels remain constantly active; the second remote device refers to a remote device whose uplink channel remains active, while the downlink channel changes its active or deactivated state according to instructions. In specific implementations, some remote devices can be selected as the first remote devices from all remote devices in the 5G DAS system. This invention refers to the first remote device as a lighthouse pRRU. The lighthouse pRRU is always active, meaning both the uplink and downlink channels remain active, allowing the transmission of cell system information so that the UE can discover and camp on the cell. This invention designates other remote devices besides the first remote devices as the second remote devices. The second remote devices can be in a power-saving state when there is no service transmission, meaning only the uplink channel is active while the downlink channel is deactivated. When the second remote device receives a wake-up command from the baseband device, it can activate the downlink channel to transmit service data. When the second remote device receives an energy-saving command from the baseband device, it can shut down the downlink channel to reduce energy consumption.

[0040] The first remote device can be determined during the planning and deployment of the indoor distribution system. The first remote device can have the following characteristics: it can weakly cover all indoor locations and has a low signaling transmission code rate.

[0041] This invention achieves energy saving by shutting down the downlink channel of the second remote device in the indoor distributed antenna system (DAS). Further, this invention selects some remote devices in the DAS to be in a normally open state (first remote device) to ensure that the UE can discover and camp on the cell. Other remote devices (second remote devices) can be in an energy-saving state when there is no service transmission, thereby reducing the energy consumption of the DAS. In addition, to promptly wake up the second remote devices in the energy-saving state, this invention configures each second remote device in the energy-saving state to only shut down its downlink channel while keeping its uplink channel open, so that the second remote device can receive the UE's uplink signal. When the baseband device determines that there is a UE's uplink signal, it identifies the target second remote device among the second remote devices and sends a wake-up command to the target second remote device to open its downlink channel, enabling the target second remote device to enter the working state. In this embodiment of the invention, the baseband device can determine whether there is a service demand based on the received uplink signal, and then send a corresponding instruction to the second remote device to change the downlink channel of the second remote device to be in an open or closed state. This enables intelligent energy-saving control of the 5G indoor distribution system, achieving the energy-saving effect of "lights following people," avoiding situations where there is no service but the equipment is still working, or there is service but the equipment is powered off, thus improving the energy-saving effect of the 5G indoor distribution system.

[0042] It should be noted that when the baseband device determines the target second remote device in the second remote device, it means that the target second remote device is determined among the second remote devices that report the uplink signal.

[0043] However, due to the complexity of the wireless environment, there may be false detections or missed detections of uplink signals. False detections will cause the downlink channel of the second remote device to be frequently activated when there is no UE actually accessing it, resulting in a decrease in energy saving effect. Missed detections will cause the downlink channel of the second remote device to not be activated in time when the UE has actual service needs, affecting the user experience.

[0044] To address this issue and further improve the energy efficiency of 5G indoor distribution systems, the method may further include: after receiving an uplink signal reported by a first remote device and / or a second remote device, determining whether the uplink signal meets the wake-up condition; the step of determining the target second remote device in the second remote device may include: if it is determined that the uplink signal meets the wake-up condition, determining the target second remote device in the second remote device.

[0045] The wake-up condition can be used to determine whether the detected uplink signal is a UE uplink signal. When the uplink signal meets the wake-up condition, it can be considered that the detected uplink signal is indeed a genuine UE uplink signal. When the uplink signal does not meet the wake-up condition, it can be considered that the detected uplink signal may be an interference signal. In this embodiment of the invention, when the remote device detects an uplink signal, it reports it to the baseband device. Only when the baseband device determines that the uplink signal meets the wake-up condition will it trigger the operation to wake up the target second remote device, thereby avoiding false detection or missed detection of uplink signals.

[0046] Reference Figure 3 The diagram shows a flowchart of an energy-saving control method according to an example of the present invention, which includes the following steps:

[0047] Step S11: The UE initiates a service and performs a random access procedure;

[0048] Step S12: The remote device (including the first remote device and the second remote device) detects the uplink signal of the UE and reports it to the baseband device;

[0049] Step S13: The second remote device waits to receive the wake-up command sent by the baseband device;

[0050] Step S14: The target second remote device receives a wake-up command sent by the baseband device;

[0051] Step S15: The target second remote device opens its own downlink channel and enters the working state.

[0052] Based on the characteristics of 5G indoor distribution systems, this embodiment of the invention utilizes a random access process to determine whether the uplink signal reported by the first remote device and / or the second remote device meets the wake-up conditions on the baseband equipment side. When it is determined that the detected uplink signal meets the wake-up conditions, the downlink channel of the target second remote device is triggered on the baseband equipment side to achieve the purpose of accurately waking up the target second remote device in energy-saving mode, and avoiding the occurrence of false detection or missed detection of uplink signals.

[0053] In an optional embodiment of the present invention, determining whether the uplink signal meets the wake-up condition may include:

[0054] Step S21: If the uplink signal is a random access first signal, then send a random access second signal through the first remote device;

[0055] Step S22: If a random access third signal is received from the first remote device and / or the second remote device, then it is determined that the random access third signal meets the wake-up condition.

[0056] In practice, when a UE camps on a cell by reading system information sent by the first remote device, and then initiates a service by receiving a paging message or actively doing so, the baseband device will receive the UE's Random Access First Signal (MSG1 signal) reported by all the first and second remote devices. Of course, the baseband device may also receive false detection signals caused by interference signals.

[0057] To avoid mistaking a false detection signal for a UE's uplink signal, the baseband device does not send a wake-up command at this time. Instead, it transmits the second random access signal (MSG2 signal) only through the first remote device. Since the first remote device has weak coverage of all indoor locations and a low signaling transmission rate, the UE can receive the MSG2 signal sent by the first remote device. If the UE is indeed initiating random access, it will continue to send the third random access signal (MSG3 signal). Similar to the MSG1 signal, the baseband device will receive the UE's MSG3 signal reported by all first and second remote devices. At this point, it can be determined that the received third random access signal meets the wake-up condition; that is, it can be confirmed that a UE is indeed attempting to access the cell, and the third random access signal is not a false detection signal.

[0058] After the baseband device receives and correctly decodes the random access third signal (MSG3 signal) from the UE, it determines the target second remote device in the second remote device and sends a wake-up command to the target second remote device to open the downlink channel of the target second remote device.

[0059] Optionally, the method may further include: sending a fourth random access signal through the first remote device and the target second remote device. After the baseband device sends a wake-up command to the target second remote device, it may also send the fourth random access signal (i.e., the MSG4 signal) through the first remote device and the target second remote device. The method may further include: receiving a fifth random access signal (i.e., the MSG5 signal) through the first remote device and the target second remote device. After the UE receives the MSG4 signal sent by the target second remote device, the UE may send the MSG5 signal to the first remote device and the target second remote device, thereby completing the random access process. The UE's service data can be transmitted through the first remote device and the target second remote device.

[0060] Reference Figure 4 The diagram shows a flow chart of an energy-saving control method in another example of the present invention. Figure 4 The sequence numbers indicate the order in which the steps are executed, as follows:

[0061] ①The UE sends the MSG1 signal, and all remote devices (including all first and second remote devices) receive the MSG1 signal and report it to the baseband device;

[0062] ②The baseband equipment sends the MSG2 signal through the first remote device;

[0063] ③The UE sends the MSG3 signal, and all remote devices (including all first and second remote devices) receive the MSG3 signal and report it to the baseband device;

[0064] ④ The baseband device selects n target second remote devices and sends the MSG4 signal through the n target second remote devices.

[0065] In an optional embodiment of the present invention, determining whether the uplink signal meets the wake-up condition may include: if the uplink signal contains service data, then determining that the uplink signal meets the wake-up condition.

[0066] For a UE in connected state, when the UE needs to transmit service data, the baseband device receives an uplink signal reported by the first and / or second remote devices in the coverage area where the UE is located. If the baseband device detects that the uplink signal contains service data, it can determine that the uplink signal meets the wake-up conditions. Here, "service data" refers to data other than random access signaling, and the service data can be data other than MSG1 to MSG5. For example, the service data may include, but is not limited to, uplink data, uplink feedback of downlink data, or SRS (Sounding Reference Signal).

[0067] In this embodiment of the invention, during the UE random access process and while the UE is in a connected state, when the baseband device receives an uplink signal reported by a first remote device and / or a second remote device, it determines whether the uplink signal meets the wake-up condition. Only when the wake-up condition is met is a wake-up command sent to the target second remote device. This embodiment of the invention uses messages in the random access process to confirm the authenticity of the uplink signal, which can solve the problem of false detection or missed detection of uplink signals and further improve the energy-saving effect of the 5G indoor distribution system.

[0068] When using contention-based random access, preamble conflicts may occur. A preamble conflict occurs when multiple UEs use the same preamble to send MSG1, and a decision must be made on which UE will ultimately succeed in accessing the network. In the event of a preamble conflict, the UE that fails to secure access will re-initiate random access, thus preventing the situation where a second remote device's downlink channel is activated but no UE service is available. Therefore, the energy-saving control method of this invention ensures that even in the event of a preamble conflict, the downlink channel of a second remote device will not be mistakenly activated.

[0069] In an optional embodiment of the present invention, determining the target second remote device in the second remote device may include: determining the target second remote device based on the strength of the uplink signal reported by the second remote device.

[0070] If the baseband equipment determines that the uplink signal meets the wake-up condition, the n devices with the strongest uplink signal strength can be identified as the target second remote devices based on the strength of the uplink signal reported by each second remote device, in order to ensure the signal transmission quality of the indoor distribution system. Here, n is a positive integer.

[0071] In an optional embodiment of the present invention, determining the target second remote device in the second remote device may include: determining the logical channel to which the second remote device that reported the uplink signal belongs, and determining all second remote devices under the logical channel as the target second remote device.

[0072] In practical implementation, if the pRRU in the indoor distribution system adopts channel merging technology, the baseband device can send the wake-up command on a logical channel basis, and all second remote devices under that logical channel can receive the wake-up command.

[0073] In one example, suppose the baseband device receives uplink signals reported by first remote device u1 and second remote devices u2, u3, u7, and u8, and determines that the uplink signals meet the wake-up conditions. Assume that second remote devices u2 and u3 belong to logical channel 1, which includes second remote devices u2, u3, u4, and u5; and that second remote devices u7 and u8 belong to logical channel 2, which includes second remote devices u7, u8, u9, and u10. Then the baseband device can determine that all second remote devices under logical channels 1 and 2 are the target second remote devices, meaning that the target second remote devices include u2, u3, u4, u5, u7, u8, u9, and u10.

[0074] In an optional embodiment of the present invention, the method may further include: after sending a wake-up command to the target second remote device, if no uplink signal meeting the wake-up conditions is received within a continuous preset time period, a power-saving command is sent to the target second remote device to shut down the downlink channel of the target second remote device.

[0075] After the baseband device sends a wake-up command to the target second remote device, if it does not receive an uplink signal that meets the wake-up conditions within a preset duration, it indicates that there is no service data at this time. In this case, it can send a power-saving command to the target second remote device to shut down the downlink channel of the target second remote device, causing the target second remote device to enter a power-saving state and reduce energy consumption. It should be noted that the specific value of the preset duration is not limited in this embodiment of the invention.

[0076] Reference Figure 5 The flowchart illustrates another embodiment of the energy-saving control method of the present invention. The method can be applied to a second remote device in an indoor distribution system. The second remote device refers to a remote device whose uplink channel remains open, and whose downlink channel changes its open or closed state according to instructions. The indoor distribution system further includes a baseband device. The method may include:

[0077] Step 501: When an uplink signal is detected, report the uplink signal to the baseband device;

[0078] Step 502: Upon receiving a wake-up command sent by the baseband device, the baseband device activates its own downlink channel in response to the wake-up command; wherein the wake-up command is sent by the baseband device when it determines that the second remote device is the target second remote device.

[0079] This invention provides an energy-saving control method applicable to indoor distribution systems, which can be 5G indoor distribution systems (hereinafter referred to as 5G indoor distribution systems). The processing procedure on the second remote device side has been described in detail in the foregoing embodiments and will not be repeated here; reference to these embodiments is sufficient.

[0080] In an optional embodiment of the present invention, the wake-up command is sent by the baseband device when it determines that the uplink signal meets the wake-up conditions. The wake-up conditions can be used to determine whether the detected uplink signal is an uplink signal of the UE.

[0081] In an optional embodiment of the present invention, the method may further include:

[0082] Upon receiving a power-saving command from the baseband device, the device shuts down its downlink channel in response to the command. The power-saving command is sent by the baseband device after it has sent a wake-up command to the second remote device and has not received an uplink signal that meets the wake-up conditions within a preset duration.

[0083] In summary, this embodiment of the invention selects some remote devices in the indoor distributed antenna system (DAS) to be in a normally-on state (first remote device) to ensure that the UE can discover and camp on the cell. Other remote devices (second remote devices) can be in an energy-saving state when there is no service transmission, thereby reducing the energy consumption of the DAS. In addition, in order to wake up the second remote devices in the energy-saving state in a timely manner, this embodiment of the invention sets each second remote device in the energy-saving state to only close the downlink channel while keeping the uplink channel open, so that the second remote device can receive the uplink signal of the UE. When the baseband device determines that there is an uplink signal of the UE, it identifies the target second remote device among the second remote devices and sends a wake-up command to the target second remote device to open the downlink channel of the target second remote device, so that the target second remote device enters the working state. In this embodiment of the invention, the baseband device can determine whether there is a service demand based on the received uplink signal, and then send a corresponding instruction to the second remote device to change the downlink channel of the second remote device to be in an open or closed state. This enables intelligent energy-saving control of the 5G indoor distribution system, achieving the energy-saving effect of "lights following people," avoiding situations where there is no service but the equipment is still working, or there is service but the equipment is powered off, thus improving the energy-saving effect of the 5G indoor distribution system.

[0112] Reference Figure 8 The diagram illustrates a structural block diagram of another embodiment of the energy-saving control device of the present invention. The device can be applied to a second remote device in an indoor distribution system. The second remote device refers to a remote device whose uplink channel remains open, and whose downlink channel changes its open or closed state according to instructions. The indoor distribution system further includes a baseband device. The device may include:

[0113] The signal reporting module 801 is used to report the uplink signal to the baseband device when an uplink signal is detected.

[0114] The channel activation module 802 is used to activate its own downlink channel in response to a wake-up command sent by the baseband device; wherein the wake-up command is sent by the baseband device when it determines that the second remote device is the target second remote device.

[0118] In this embodiment of the invention, some remote devices in the indoor distributed antenna system (DAS) are kept in a normally-on state (first remote device) to ensure that the UE can discover and camp on the cell. Other remote devices (second remote devices) can be in an energy-saving state when there is no service transmission, thereby reducing the energy consumption of the DAS. In addition, in order to wake up the second remote devices in the energy-saving state in a timely manner, this embodiment of the invention sets each second remote device in the energy-saving state to only close the downlink channel while keeping the uplink channel open, so that the second remote device can receive the uplink signal of the UE. When the baseband device determines that there is an uplink signal of the UE, it identifies the target second remote device among the second remote devices and sends a wake-up command to the target second remote device to open the downlink channel of the target second remote device, so that the target second remote device enters the working state. In this embodiment of the invention, the baseband device can determine whether there is a service demand based on the received uplink signal, and then send a corresponding instruction to the second remote device to change the downlink channel of the second remote device to be in an open or closed state. This enables intelligent energy-saving control of the 5G indoor distribution system, achieving the energy-saving effect of "lights following people," avoiding situations where there is no service but the equipment is still working, or there is service but the equipment is powered off, thus improving the energy-saving effect of the 5G indoor distribution system.
