Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to relay methods and relay equipment. Background Technology

[0002] The distance between the base station and the user equipment (UE) may be large, or there may be objects between the base station and the UE that the signal cannot easily penetrate. For example, when the UE is in a vertically moving elevator, there is an elevator car between the UE and the base station where the signal cannot easily penetrate. In such scenarios, the signal strength will experience significant attenuation. Therefore, it is necessary to deploy relay equipment between the base station and the UE to amplify the signal, increasing the probability of the signal being received at the receiver, or to increase the received signal strength, thereby facilitating signal analysis at the receiver.

[0003] For relay equipment, existing energy-saving solutions involve putting some devices into sleep mode during a configured time period. If latency-sensitive data needs to be transmitted during this period, it will be unable to be transmitted due to the relay equipment being in sleep mode, causing interruptions to these services. For example, when the latency-sensitive service is autonomous driving, remote surgery, or emergency broadcasting, the interruption could threaten lives. Summary of the Invention

[0004] This application provides a relay method and relay equipment to achieve energy saving of the relay equipment without affecting services.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, a communication method is provided. The apparatus for executing the relay method can be a relay device, or a module applied in the relay device to implement its communication function, such as a chip, a chip system, a module, or a component. The relay method includes: acquiring a first time-domain position of a first downlink signal, the first downlink signal being a downlink signal of a first service; receiving the first downlink signal and transmitting an amplified version of the first downlink signal at the first time-domain position; receiving a second downlink signal but ceasing to transmit the amplified second downlink signal, or ceasing to receive the second downlink signal, at a time-domain position other than the first time-domain position; the second downlink signal being a downlink signal other than the first downlink signal.

[0007] In the relay method provided in this application embodiment, the relay device receives the second downlink signal but stops transmitting the amplified second downlink signal at a time domain position other than the first time domain position, that is, some or all devices in the downlink transmission channel go into sleep mode. Alternatively, the relay device stops receiving the second downlink signal at a time domain position other than the first time domain position, that is, some or all devices in the downlink receiving channel and the downlink transmission channel go into sleep mode, thereby achieving energy saving of the relay device. However, at the first time domain position, the relay device processes the first downlink signal normally, thereby ensuring the normal operation of the first service. Therefore, the relay method provided in this application embodiment can achieve energy saving of the relay device without affecting the first service.

[0008] In conjunction with the first aspect described above, in one possible implementation, receiving a second downlink signal but ceasing to transmit the amplified second downlink signal, or ceasing to receive the second downlink signal, at a time domain location other than the first time domain location, includes: if no uplink signal of the first service is detected during the timer's operation, receiving a second downlink signal but ceasing to transmit the amplified second downlink signal, or ceasing to receive the second downlink signal, at a time domain location other than the first time domain location. This scheme can be implemented around the clock. As long as the condition that no uplink signal of the first service is detected during the timer's operation is met, the relay device can go into sleep mode while ensuring the normal operation of the first service. This helps to increase the sleep time of some components in the relay device, thereby improving the energy-saving effect of the relay device.

[0009] In conjunction with the first aspect described above, in one possible implementation, the method further includes: receiving an uplink signal of the first service from a terminal device; receiving the first downlink signal at the first time domain location and transmitting the amplified first downlink signal; and receiving the second downlink signal at a time domain location other than the first time domain location and transmitting the amplified second downlink signal. In this scheme, when some or all devices in the downlink transmission channel of the relay device are in sleep mode, the uplink signal receiving module is not in sleep mode. Once the uplink signal receiving module detects (or receives) the uplink signal of the first service, the relay device can exit sleep mode, normally receive the first downlink signal and the second downlink signal, amplify them, and transmit them to the terminal device.

[0010] In conjunction with the first aspect described above, in one possible implementation, the first time-domain location is either pre-configured or obtained from a network device. In this scheme, if the first time-domain location is pre-configured, the scheme primarily relies on manual processing, resulting in low hardware processing costs and faster implementation. If the first time-domain location is obtained from a network device, the scheme can automate the acquisition of the first time-domain location, thereby saving manpower.

[0011] In conjunction with the first aspect described above, in one possible implementation, the first time-domain location is stored in a table. In this scheme, in other words, the first time-domain location can be stored in the relay device in the form of a table. Exemplarily, the table can also be referred to as a shutdown identifier table, or a pattern table.

[0045] In the embodiments of this application, "hibernate" and "shutdown" can be used interchangeably. This is stated uniformly here and will not be repeated below.

[0046] Currently, depending on the different devices that go into sleep mode during the configured time period, energy-saving schemes for relay equipment can include channel sleep mode, carrier sleep mode, and deep sleep mode. In the channel sleep mode, some or all devices within the RF channel may go into sleep mode. In the carrier sleep mode, devices operating in a specified frequency band may go into sleep mode. In the deep sleep mode, the chip containing the timer used to control wake-up or sleep time, as well as the power supply devices, do not go into sleep mode, while the remaining devices go into sleep mode to maximize energy savings.

[0047] On the one hand, to minimize the impact on services and avoid dropped calls or video buffering to ensure a good user experience, the configured time period is usually a period with a low expected number of UEs accessing the network, such as between 2 AM and 3 AM. This results in a shorter configured time period and poorer energy-saving performance. On the other hand, if latency-sensitive services need to transmit data during the configured time period, this data will be unable to be transmitted normally due to the relay equipment being in sleep mode, causing interruptions to these latency-sensitive services. For example, when latency-sensitive services are autonomous driving, telemedicine, or emergency broadcasting, the interruption can threaten life safety.

[0048] To address the aforementioned issues, in this embodiment of the application, the relay device still allows the downlink signal of the first service to pass through when it is in sleep mode, thereby ensuring the normal operation of the first service.

[0049] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. In the description of this application, unless otherwise stated, " / " indicates that the objects before and after are in an "or" relationship. For example, A / B can represent A or B. "And / or" in this application is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone, where A and B can be singular or plural. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more.

For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple. Furthermore, to facilitate a clear description of the technical solutions in the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with substantially the same function and effect. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and that "first" and "second" are not necessarily different.

Specifically, for downlink signals sent by the network device 101, the relay device 102 can amplify the received downlink signals before sending them to the terminal device 103; for uplink signals sent by the terminal device 103, the relay device 102 can amplify the received uplink signals before sending them to the network device 101.

[0052] In one possible implementation, relay device 102 is used to obtain the first time-domain position of the first downlink signal, which is the downlink signal of the first service. Network device 101 is used to send the first downlink signal and a second downlink signal to relay device 102, where the second downlink signal is a downlink signal other than the first downlink signal. Accordingly, relay device 102 is also used to receive the first downlink signal from network device 101 at the first time-domain position and send the amplified first downlink signal to terminal device 103; at time-domain positions other than the first time-domain position, it receives the second downlink signal from network device 101 but stops sending the amplified second downlink signal to terminal device 103, or stops receiving the second downlink signal from network device 101. Accordingly, terminal device 103 is used to receive the amplified first downlink signal from relay device 102.

The RU can be included in radio frequency equipment or radio frequency units, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). It is understood that network device 101 can be a CU node, a DU node, or a device including both CU and DU nodes. Furthermore, the CU can be classified as a network device in the radio access network (RAN) or a network device in the core network (CN); no restrictions are placed here.

[0058] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open (O) RAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0077] Step S301: The relay device acquires the first time domain position of the first downlink signal.

[0078] Among them, the first downlink signal is the downlink signal of the first service.

[0079] For example, the first service may be a network access service, or it may be a latency-sensitive service, such as an autonomous driving service, a telemedicine service, or an emergency broadcast service.

[0080] For example, the first time-domain location may include the Mth symbol in the Nth frame, where N and M are natural numbers.

[0081] Optionally, the first downlink signal includes one or more of the following: paging message, system message, or synchronization signal and physical broadcast channel block (SPSB). This scheme can be applied when the first service is a network access service. In this scheme, the first downlink signal can be used for the terminal device to access the network, or for the terminal device to initiate an RRC connection establishment or re-establishment procedure.

[0082] Optionally, the first time-domain location is stored in a table. In this scheme, in other words, the first time-domain location can be stored in the relay device in the form of a table. Exemplarily, the table can also be referred to as a shutdown identification table or a pattern table.

[0083] Step S302: The network device sends a first downlink signal to the relay device at the first time domain location. Correspondingly, the relay device receives the first downlink signal from the network device at the first time domain location.

[0084] In the first time domain position, the relay device can normally receive the first downlink signal and amplify the first downlink signal.

[0085] For example, in step S302, the operation of the relay device can be performed by the downlink signal receiving module included in the relay device.

[0086] Step S303: The relay device sends an amplified first downlink signal to the terminal device at the first time domain location. Correspondingly, the terminal device receives the amplified first downlink signal from the relay device at the first time domain location.

[0087] The relay device can transmit the amplified first downlink signal normally, thereby ensuring the normal operation of the first service.

[0088] For example, in step S303, the operation of the relay device can be performed by the downlink signal transmission module included in the relay device.

[0089] Optionally, steps S304a and S305a can be performed, or step S304b can be performed.

[0090] Step S304a: The network device transmits a second downlink signal to the relay device at a time domain location other than the first time domain location. Correspondingly, the relay device receives the second downlink signal from the network device at a time domain location other than the first time domain location.

[0091] The second downlink signal is a downlink signal other than the first downlink signal.

[0092] Step S305a: The relay device stops (disables) sending the amplified second downlink signal to the terminal device at a time domain position other than the first time domain position.

[0093] In the embodiments of this application, the relay device stopping the transmission (or reception) of the second downlink signal can also be alternatively described as: the relay device interrupting the transmission (or reception) of the second downlink signal; the relay device remaining silent in the transmission (or reception) of the second downlink signal; or, the relay device closing the downlink transmission channel (or closing the downlink reception channel and the downlink transmission channel) at a time domain position other than the first time domain position.

[0094] In steps S304a and S305a above, at time domain positions other than the first time domain position, the relay device can normally receive the second downlink signal, but stops transmitting the amplified second downlink signal. That is, some or all devices in the downlink transmission channel of the relay device go into sleep mode; or, the downlink transmission module goes into sleep mode, thereby achieving energy saving of the relay device.

[0095] Optionally, steps S302 and S303 can be executed first, followed by steps S304a and S305a; or, steps S304a and S305a can be executed first, followed by steps S302 and S303, without restriction.

[0096] Step S304b: The network device sends a second downlink signal to the relay device at a time domain location other than the first time domain location. However, the relay device stops receiving the second downlink signal from the network device at a time domain location other than the first time domain location.

[0097] Specifically, at time domain positions other than the first time domain position, the relay device can stop receiving the second downlink signal and will not transmit the amplified second downlink signal. In other words, some or all devices in the downlink receiving and downlink transmitting channels of the relay device go into sleep mode; or, the downlink receiving module and the downlink transmitting module go into sleep mode, thereby achieving energy saving of the relay device.

[0098] Optionally, steps S302 and S303 can be executed first, followed by step S304b, or steps S304b can be executed first, followed by steps S302 and S303, without restriction.

[0099] When the first time-domain location includes the Mth symbol in the Nth frame, the relay device can implement the sleep mode of some devices at the symbol level by step S304b, or by steps S304a and S305a.

[0100] In the relay method provided in this application embodiment, the relay device receives the second downlink signal but stops transmitting the amplified second downlink signal at a time domain position other than the first time domain position, that is, some or all devices in the downlink transmission channel go into sleep mode. Alternatively, the relay device stops receiving the second downlink signal at a time domain position other than the first time domain position, that is, some or all devices in the downlink receiving channel and the downlink transmission channel go into sleep mode, thereby achieving energy saving of the relay device. However, at the first time domain position, the relay device processes the first downlink signal normally, thereby ensuring the normal operation of the first service. Therefore, the relay method provided in this application embodiment can achieve energy saving of the relay device without affecting the first service.

[0101] Optionally, the condition for performing step S304b (or steps S304a and S305a) can be: the relay device does not detect the uplink signal of the first service during the timer's operation. This scheme can be implemented around the clock. As long as the condition that the uplink signal of the first service is not detected during the timer's operation is met, the relay device can go into sleep mode while ensuring the normal operation of the first service. This helps to increase the sleep time of some components in the relay device, thereby improving the energy-saving effect of the relay device.

[0102] For example, the detection of the uplink signal of the first service can be performed by the uplink signal receiving module included in the relay device.

[0103] The following describes the method by which a relay device (or a cooperative control module included in the relay device) obtains the first time domain position. The method of obtaining the position is not limited to the methods listed below, and this application does not limit it.

[0104] In one possible implementation, the first time-domain location is pre-configured. In this scheme, the relay device obtains the first time-domain location by manually reading it from the network device and then writing it into the relay device. This scheme primarily relies on manual processing, thus resulting in low hardware processing costs and faster implementation.

[0105] For example, the first time-domain location can be pre-configured in the cooperative control module, which controls the transmission of the second downlink signal based on whether the uplink signal receiving module detects the uplink signal of the first service. In other words, this implementation is one possible way for the cooperative control module to obtain the first time-domain location.

[0106] In another possible implementation, the first time-domain location is obtained from the network device. In this scheme, the relay device obtains the first time-domain location by parsing the information from the network device. This scheme can automate the acquisition of the first time-domain location, thus saving manpower.

[0107] For example, the relay device includes a downlink signal receiving module that can receive information from a network device and transmit that information to a signal parsing module included in the relay device. The signal parsing module can parse the information to obtain a first time-domain location. Then, the signal parsing module can transmit the first time-domain location to the coordination control module.

[0108] For example, when the first downlink signal includes one or more of the following: paging message, system message, or SSB, the specific process of the signal parsing module in parsing can be referred to the prior art, and will not be repeated here.

[0109] Based on the modules included in the relay device, the following describes the specific implementation of step S304b, or steps S304a and S305a, when the relay device does not detect the uplink signal of the first service during the timer operation.

[0110] In one possible implementation, if the relay device does not detect the uplink signal of the first service during the timer's operation, step S304b described above is executed. For example, the uplink signal receiving module can transmit first indication information to the coordination control module, indicating that the uplink signal receiving module did not detect the uplink signal of the first service during the timer's operation. Accordingly, the coordination control module acquires the first indication information and transmits a first control signaling to the downlink signal transmitting module, controlling the downlink signal transmitting module to transmit the amplified first downlink signal at a first time domain position. The coordination control module can also transmit a second control signaling to the downlink signal receiving module, controlling the downlink signal receiving module to stop receiving the second downlink signal at time domain positions other than the first time domain position. In other words, the second control signaling controls the downlink signal receiving module to go into sleep mode at time domain positions other than the first time domain position. Accordingly, at time domain positions other than the first time domain position, since there is no signal input to the relay device, i.e., no signal to be processed (or amplified), the downlink signal transmitting module can also go into sleep mode. This enables the downlink signal transmission module to transmit the amplified first downlink signal at the first time domain position.

[0111] In another possible implementation, if the relay device does not detect the uplink signal of the first service during the timer's operation, steps S304a and S305a are executed as described above. For example, the uplink signal receiving module can transmit first indication information to the coordination control module, indicating that the uplink signal receiving module did not detect the uplink signal of the first service during the timer's operation. Accordingly, the coordination control module acquires the first indication information and transmits a first control signaling to the downlink signal transmitting module, controlling the downlink signal transmitting module to transmit the amplified first downlink signal at a first time domain position. In other words, the first control signaling controls the downlink signal transmitting module to sleep at time domain positions other than the first time domain position. In this implementation, the downlink signal receiving module can receive the second downlink signal at time domain positions other than the first time domain position. That is, the downlink signal receiving module does not sleep at time domain positions other than the first time domain position.

[0112] In this embodiment of the application, during the execution of step S304b, or steps S304a and S305a, the uplink signal receiving module does not go into sleep mode. Once the uplink signal receiving module detects (or receives) the uplink signal of the first service, the relay device can exit sleep mode and normally receive the first downlink signal and the second downlink signal, amplify them, and send them to the terminal device. The specific description is as follows:

[0113] Optionally, the relay method provided in this application further includes: a terminal device sending an uplink signal of a first service to a relay device; correspondingly, the relay device receiving the uplink signal of the first service from the terminal device. A network device sending a first downlink signal to the relay device at a first time domain location. Correspondingly, the relay device receiving the first downlink signal from the network device at the first time domain location and sending an amplified first downlink signal to the terminal device. Correspondingly, the terminal device receiving the amplified first downlink signal from the relay device. The network device sending a second downlink signal to the relay device at a time domain location other than the first time domain location. Correspondingly, the relay device receiving the second downlink signal from the network device at a time domain location other than the first time domain location and sending an amplified second downlink signal to the terminal device. Correspondingly, the terminal device receiving the amplified second downlink signal from the relay device.

[0114] For example, if the first service is a network access service, the uplink signal of the first service can be a random access request message.

[0115] For example, the uplink signal receiving module can transmit second indication information to the cooperative control module, the second indication information being used to instruct the uplink signal receiving module to receive the uplink signal of the first service.

[0116] In one possible implementation, if steps S304a and S305a are executed, the downlink receiving module is not in sleep mode. In this implementation, the cooperative control module can acquire the second indication information and transmit the second control signaling to the downlink signal transmitting module; the second control signaling is used to control the downlink signal transmitting module to transmit the amplified first downlink signal and the amplified second downlink signal. Thus, the downlink signal transmitting module is in working state at the first time domain position and at all other time domain positions, that is, the downlink signal transmitting module transmits the amplified first downlink signal at the first time domain position and transmits the amplified second downlink signal at all other time domain positions.

[0117] In another possible implementation, if step S304b is executed, the downlink receiving module goes into sleep mode at time domain positions other than the first time domain position. In this implementation, the cooperative control module can wake up the downlink receiving module at time domain positions other than the first time domain position according to the second indication information. Specifically, the cooperative control module can obtain the second indication information and transmit a fourth control signaling to the downlink signal receiving module. The fourth control signaling is used to control the downlink signal receiving module to receive the first downlink signal and the second downlink signal. The cooperative control module can also transmit a third control signaling to the downlink signal transmitting module. The third control signaling is used to control the downlink signal transmitting module to transmit the amplified first downlink signal and the amplified second downlink signal. Thus, the downlink receiving module and the downlink transmitting module are in working state at all time domain positions. That is, at the first time domain position, the downlink signal receiving module receives the first downlink signal, and the downlink signal transmitting module transmits the amplified first downlink signal; at time domain positions other than the first time domain position, the downlink signal receiving module receives the second downlink signal, and the downlink signal transmitting module transmits the amplified second downlink signal.

[0134] The relevant description of step S406b can be found in the relevant description of step S304b above, and will not be repeated here.

[0135] Step S408: The terminal device sends an uplink signal for the first service to the relay device. Correspondingly, the relay device receives the uplink signal for the first service from the terminal device.

[0136] Step S408 can be understood as the trigger condition for the relay device to exit sleep mode. Specifically, step S408 can be understood as the trigger condition for subsequent steps S409 to S412.

[0137] Step S409: The network device sends a first downlink signal to the relay device at the first time domain location. Correspondingly, the relay device receives the first downlink signal from the network device at the first time domain location.
