Description

[Technical Field]

[0001] The present invention relates to the technical field of wireless communications. [Background technology]

[0002] Compared with the traditional 3G (third generation mobile communication technology) and 4G (fourth generation mobile communication technology) systems, 5G (fifth generation mobile communication technology) systems can provide larger bandwidths and higher data rates, and can support more types of terminals and vertical services. Therefore, the frequencies at which 5G systems are deployed are typically significantly higher than those of 3G and 4G systems. For example, 5G systems can be deployed in the millimeter wave band.

[0003] However, the higher the carrier frequency, the greater the attenuation the signal will encounter during the transmission process. Therefore, in the actual deployment of 5G systems, how to better enhance cell coverage has become a problem to be solved, especially in the millimeter wave band.

[0004] It should be noted that the introduction of the above background art is intended to clearly and completely explain the technical solutions of the present invention and to facilitate understanding by those skilled in the art, and these technical solutions described in the background art of the present invention should not be construed as being known to those skilled in the art. Summary of the Invention [Problem to be solved by the invention]

[0005] To better solve the coverage problem in the actual deployment of cellular mobile communication systems, a commonly used deployment method is to adopt an RF relay / repeater to amplify and forward communication signals between terminal devices and network devices. RF relays are relatively widely used in the actual deployment of 3G and 4G systems. Generally speaking, an RF relay is a device that amplifies and forwards round-trip signals between network devices and terminal devices in the RF domain.

[0006] A conventional RF transmitter does not demodulate / decode the transmitted signal during the transmission process. The antenna direction of a conventional RF transmitter is fixed. The antenna direction of a conventional RF transmitter is usually manually installed and adjusted during initial installation, so that the antenna on the base station side is oriented toward the direction of the base station's incoming wave, and the antenna on the terminal side is oriented toward the location where deployment needs to be strengthened. The antenna direction does not change during the working process of a conventional RF transmitter. In addition, a conventional RF transmitter does not have a communication function and cannot perform information interaction with a base station, and therefore does not support the base station to perform adaptive and / or dynamic configurations on it.

[0007] Compared with 3G and 4G systems, 5G systems deployed in relatively high frequency bands and millimeter wave frequency bands utilize more advanced and complex MIMO (Multiple Input Multiple Output) technology. In 5G systems, directional antennas are the basic components of base stations and terminal devices, and the basic signal transmission method in 5G systems is to transmit and receive signals based on beamforming technology.

[0008] In particular, the millimeter wave band is characterized by high frequencies and short wavelengths, which makes it advantageous to install antenna panels containing a relatively large number of arrays in base stations and terminal devices. Increasing the number of antenna arrays can facilitate more accurate beamforming, i.e., it is easier to form narrow beams. Concentrating energy in narrow beams is beneficial for signal strengthening and also reduces interference with other devices. In addition, because the direction of narrow beams is precise and the requirements for channel measurement and beam management are very high, 5G systems support complex and accurate channel measurement, antenna calibration, and beam management schemes, which allow base stations to effectively and accurately control the receiving and transmitting beams of terminal devices, thereby achieving better communication results.

[0009] The inventors have discovered that using an RF forwarder to enhance coverage is one possible solution to the coverage problem that 5G systems will encounter during deployment. However, the antenna of a conventional RF forwarder cannot dynamically adjust its direction and has a relatively wide beam. Although such an RF forwarder can help enhance signal strength when deployed in a 5G system, its relatively wide transmission beam can cause significant interference to other surrounding base stations or terminal devices, which may increase the new interference and reduce the overall network throughput.

[0010] In consideration of at least one of the above problems, embodiments of the present invention provide a forwarder, a network device, and a communication method thereof. The forwarder communicates with the network device to receive instructions or settings (e.g., beam instructions or settings, forwarding bandwidth, etc.) about forwarding made by the network device according to the real-time situation of the network, and then forwards signals based on the instructions or settings. The adoption of the forwarder in the implementation scheme of the present invention can better enhance signal coverage and better reduce interference to other surrounding devices, thereby improving the transmission efficiency of the entire network. [Means for solving the problem]

[0035] 1, the forwarder is described as being capable of forwarding signals between a network device and a terminal device, but the present invention is not limited thereto. For example, the forwarder may be a second device that forwards signals between a first device and a third device, and may also communicate directly with the first device and / or the third device. The first device to the third device may be any device in the network described above. In the following embodiment, the first device is described as a network device and the third device is described as a terminal device.

[0036] Various implementations of the present invention will be described below with reference to the accompanying drawings, which are merely examples and are not intended to limit the present invention.

[0037] <Example of the first aspect> In the embodiment of the present invention, a communication method for a forwarder is provided, and will be explained from the forwarder side.

[0038] 2 is a diagram illustrating a communication method of a forwarder in an embodiment of the present invention. As shown in FIG. 2, the method includes the following steps:

[0039] 202: The forwarder forwards signals from the network device using a predefined or network device directed or configured beam, and / or the forwarder forwards signals to the network device using a predefined or network device directed or configured beam.

[0040] In some embodiments, optionally, as shown in FIG. 2, the method may further include the following steps:

[0041] 201: A forwarder receives configuration information for directing or configuring the forwarder's beam of network device transmissions.

[0042] Note that, although the above-mentioned FIG. 2 is used to exemplify an embodiment of the present invention, the present invention is not limited thereto. For example, the execution order of each operation (step) can be appropriately adjusted, or some other operations can be added or removed. Those skilled in the art can make appropriate modifications based on the above content without being limited to the description of the above-mentioned FIG. 2.

[0043] In an embodiment of the present invention, a beam may be represented as a lobe, a reference signal (RS), a transmission configuration indication (TCI), a spatial domain filter, etc. Alternatively, it may be represented as a beam index, a lobe index, a reference signal index, a transmission configuration indication index, a spatial domain filter index, etc. The above-mentioned reference signal may be, for example, a channel state information reference signal (CSI-RS), a sounding reference signal (SRS), an RS used by a transmitter, an RS transmitted by a transmitter, etc. good The above TCI may also be expressed as a TCI state.

[0044] In embodiments of the present invention, a forwarder may also be referred to as a forwarder, RF forwarder, repeater, RF repeater; forwarder node, forwarder node, repeater node; smart forwarder, smart forwarder, smart repeater, smart forwarder node, smart forwarder node, smart repeater node, etc., but the present invention is not limited thereto.

[0045] In an embodiment of the present invention, the network device may be a device of the serving cell of the terminal device; a device of the cell in which the forwarder is located; a device of the serving cell of the forwarder; a parent node of the forwarder, etc., but the present invention does not limit the name of the forwarder, and all devices that can realize the above-mentioned functions are included in the scope of the forwarder of the present invention.

[0046] In an embodiment of the present invention, the predefined beam or the beam instructed or set by the network device for the forwarder may be a receiving beam of the forwarder, for example, a receiving beam for receiving a signal from the network device, or a receiving beam for receiving a signal from a terminal device, and the predefined beam or the beam instructed or set by the network device for the forwarder may be a transmitting beam of the forwarder, for example, a transmitting beam for a signal to be transmitted to the network device, or a transmitting beam for a signal to be transmitted to the terminal device.

[0047] The network device can instruct or set the beam of the forwarder, for example, it can be set dynamically or semi-statically, or the beam of the forwarder can be predefined. Therefore, compared with the conventional scheme in which the direction of the antenna of the forwarder cannot be dynamically adjusted, the forwarder in the embodiment of the present invention can forward signals according to the predefined beam or the beam instructed or set by the network device, thereby achieving better signal coverage and reducing interference to other surrounding devices, thereby improving the transmission efficiency of the entire network.

[0048] In 201 of Figure 2, configuration information may be sent by the network device to the forwarder, for example, MAC (Medium Access Control) layer signaling or RRC (Radio Resource Control) signaling, but the present invention is not limited thereto. After receiving the configuration information, the forwarder can perform corresponding processing, such as signal measurement and reporting, beam selection, etc. The information exchanged between the network device and the forwarder is not limited to configuration information, and may also include various other control information and / or data information.

[0049] Hereinafter, for convenience, signals communicated between a network device and a forwarder, or between a third device (e.g., a terminal device) and a forwarder are referred to as communication signals (e.g., the fifth and sixth signals, and the seventh and eighth signals below). Among them, a downlink communication signal, such as the fifth signal, is used by a network device to configure, schedule, instruct, etc., the forwarder, and the forwarder needs to decode and / or demodulate the downlink communication signal; or a downlink communication signal, such as the seventh signal, is used by a third device to perform channel measurement or estimation (e.g., a reference signal), and the forwarder generates the downlink communication signal; or is used by a forwarder to transmit information or data, etc., to the third device, and the forwarder needs to encode and / or modulate the downlink communication signal.

[0050] The uplink communication signal may be, for example, a sixth signal, which the forwarder uses to report, feedback, etc. to the network device, and which the forwarder must encode and / or modulate; or the uplink communication signal may be, for example, an eighth signal, which the forwarder uses to perform channel measurements or estimations (e.g., reference signals), and which the forwarder must receive, etc., on the uplink communication signal, or which a third device uses to transmit information, data, etc. to the forwarder, and which the forwarder must decode and / or demodulate, the uplink communication signal.

[0051] In addition, signals between the network device and the third device that are forwarded via the forwarder are called forwarded signals (e.g., the first signal, second signal, third signal, and fourth signal below), and the forwarder may perform signal processing such as filtering and amplification on the forwarded signals, but does not perform decoding and / or demodulation.

[0052] In some embodiments, the forwarder receives a first signal from a network device using a predefined first beam or a first beam directed or configured by the network device, the forwarder performs signal processing on the first signal to generate a second signal; and the forwarder transmits the second signal to a third device using a predefined second beam or a second beam directed or configured by the network device.

As shown in FIG. 3, a network device can transmit a first signal to the forwarder using a transmission beam, and the first signal is, for example, for scheduling a terminal device. The forwarder receives the first signal using the first beam (e.g., a reception beam instructed or set by the network device, or, for example, a predefined reception beam), and generates a second signal after performing signal processing (e.g., amplification, etc.) on the first signal. The forwarder can then transmit the second signal to the terminal device using the second beam (e.g., a transmission beam instructed or set by the network device, or, for example, a predefined transmission beam). The terminal device receives the second signal using a reception beam (e.g., instructed or set by the network device, or, for example, predefined).

[0054] In some embodiments, the forwarder receives a third signal from a third device using a predefined third beam or a network device-directed or configured third beam, the forwarder performs signal processing on the third signal to generate a fourth signal, and the forwarder transmits the fourth signal to the network device using a predefined fourth beam or a network device-directed or configured fourth beam.

[0055] 4 is a diagram illustrating an example in which a forwarder forwards an uplink signal in an embodiment of the present invention. As shown in FIG. 4, the terminal device transmits a third signal using a transmission beam (e.g., instructed or set by a network device, and e.g., predefined), and the third signal is used, for example, by the terminal device to report to the network device. The forwarder receives the third signal using the third beam (a receiving beam instructed or set by the network device, and e.g., a predefined coherent beam), and generates a fourth signal after performing signal processing (e.g., amplification, etc.) on the third signal. The forwarder can transmit the fourth signal to the network device using the fourth beam (a transmitting beam instructed or set by the network device, and e.g., a predefined transmitting beam). The network device can receive the fourth signal transmitted by the forwarder using the receiving beam.

[0056] The above describes, by way of example, the forwarder forwarding signals (including uplink forwarding signals and downlink forwarding signals) between a network device and a third device (e.g., a terminal device). Below, the communication signals (including uplink communication signals and downlink communication signals) between the forwarder and the network device will be further described.

[0057] In some embodiments, the forwarder receives a fifth signal from the network device using a predefined fifth beam or a fifth beam directed or configured by the network device, and the forwarder demodulates and / or decodes the fifth signal.

[0058] 5 is a diagram illustrating an example of a forwarder receiving a downlink signal in an embodiment of the present invention. As shown in FIG. 5, the network device can use a transmit beam to transmit a fifth signal to the forwarder, where the fifth signal is, for example, for scheduling or configuring the forwarder. The forwarder can receive the fifth signal using the fifth beam (e.g., a receive beam instructed or configured by the network device, e.g., a predefined receive beam), and then demodulate / decode the fifth signal to perform corresponding processing based on the content carried by the fifth signal, such as obtaining information carried by the fifth signal and / or performing channel estimation or channel measurement using a reference signal carried by the fifth signal.

[0059] In some embodiments, the forwarder generates the sixth signal, and the forwarder transmits the sixth signal to the network device using a predefined sixth beam or a network device directed or configured sixth beam.

[0060] 6 is a diagram illustrating an example of a forwarder transmitting an uplink signal in an embodiment of the present invention. As shown in FIG. 6, the forwarder generates a sixth signal (e.g., includes modulation / coding), and the sixth signal is used, for example, by the forwarder to report measurement results or feedback information to the network device. The forwarder can transmit the sixth signal to the network device using a sixth beam (e.g., a transmission beam instructed or set by the network device, also, for example, a predefined transmission beam). The network device can receive the sixth signal transmitted by the forwarder using a receiving beam and perform corresponding processing based on the content carried by the sixth signal.

[0061] The communication signals (including uplink communication signals and downlink communication signals) between the forwarder and a third device (eg, a terminal device) are further described below.

[0062] In some embodiments, the forwarder generates a seventh signal, and the forwarder transmits the seventh signal to the third device using a predefined seventh beam or a network device directed or configured seventh beam.

[0063] 7 is a diagram illustrating an example in which a forwarder transmits a downlink signal in an embodiment of the present invention. As shown in FIG. 7, the forwarder generates a seventh signal (e.g., including modulation / coding, or generating and modulating a sequence of reference signals), and the seventh signal is used, for example, by a terminal device to perform channel measurement or estimation (e.g., a reference signal), or is used by the forwarder to transmit information or data to the terminal device. The forwarder can transmit the seventh signal to the terminal device using a seventh beam (e.g., a transmission beam instructed or set by a network device, or, for example, a predefined transmission beam). The terminal device can receive the seventh signal transmitted by the forwarder using a receiving beam and perform corresponding processing based on the content carried by the seventh signal.

[0064] In some embodiments, the forwarder receives an eighth signal from the third device using a predefined eighth beam or an eighth beam directed or configured by the network device, and the forwarder demodulates and / or decodes the eighth signal.

[0065] 8 is a diagram illustrating an example in which a forwarder receives an uplink signal in an embodiment of the present invention. As shown in FIG. 8, the terminal device can transmit an eighth signal to the forwarder using a transmission beam. The eighth signal is, for example, used by the forwarder to perform channel measurement or estimation (e.g., a reference signal), or used by the terminal device to transmit information or data to the forwarder. The forwarder receives the eighth signal using the eighth beam (e.g., a receive beam instructed or set by a network device, or, for example, a predefined receive beam), and can demodulate / decode the eighth signal to perform corresponding processing based on the content carried by the eighth signal.

[0066] 3 to 8 illustrate examples of transmission signals and communication signals, respectively, but the present invention is not limited thereto. The transmission signals and communication signals may be transmitted independently or may be combined into one signal for transmission. For example, one or any combination of time division (TD), frequency division (FD), code division (CD), space division, etc. may be used, but the present invention is not limited thereto.

[0067] In some embodiments, the fifth signal that the network device sends to the forwarder and the first signal that the network device sends to the third device via the forwarder are included in the same signal from the network device.

[0068] For example, the time domain resources of the fifth signal and the time domain resources of the first signal are at least partially the same, the frequency domain resources of the fifth signal and the frequency domain resources of the first signal are different, and / or the code domain resources of the fifth signal and the code domain resources of the first signal are different.

[0069] 9 is a diagram illustrating an example of multiplexing of signal transmission resources and signal communication resources in an embodiment of the present invention. As shown in FIG. 9, for example, the resource for transmitting the fifth signal is resource 1, and the resource for transmitting the first signal is resource 2, and resource 1 and resource 2 are the same in the time domain (e.g., located in the same symbol in the same slot) but different in the frequency domain.

[0070] 10 is a diagram illustrating another example of multiplexing of signal transmission resources and signal communication resources in an embodiment of the present invention. As shown in FIG. 10, for example, the resource for transmitting the fifth signal is resource 1, and the resource for transmitting the first signal is resource 2, and resource 1 and resource 2 are partially the same in the time domain (for example, some symbols overlap), but are different in the frequency domain.

[0071] Also, for example, the frequency domain resources of the fifth signal and the frequency domain resources of the first signal are at least partially the same, the time domain resources of the fifth signal and the time domain resources of the first signal are different, and / or the code domain resources of the fifth signal and the code domain resources of the first signal are different.

[0072] 11 is a diagram illustrating another example of multiplexing of signal transmission resources and signal communication resources in an embodiment of the present invention. As shown in FIG. 11, for example, the resource for transmitting the fifth signal is resource 1, and the resource for transmitting the first signal is resource 2, and resource 1 and resource 2 are partially the same in the frequency domain (for example, some subcarriers overlap), but are different in the time domain.

[0073] In some embodiments, the fifth signal and the first signal within one time unit are orthogonal, and after receiving the same signal, the forwarder and / or the terminal device can derive the fifth signal and / or the first signal from the same signal using the orthogonality between the fifth signal and the first signal.

[0074] For example, the time-frequency resource of the fifth signal and the time-frequency resource of the first signal are within one time unit, and the time unit may be one of the following: a symbol, a slot, a sub-frame, a mini-slot, or a smallest scheduling unit not based on slot scheduling.

[0075] The time-frequency resources of the fifth signal are orthogonal to the time-frequency resources of the first signal, and / or the code domain resources of the fifth signal are orthogonal to the code domain resources of the first signal, and / or the fifth signal is orthogonal to the first signal in the spatial domain, etc.

[0076] This allows the downlink communication signal that the network device sends to the forwarder and the downlink forwarding signal that the network device sends to the third device via the forwarder to be included in the same signal.

[0077] 12 is a diagram illustrating an example of a forwarder according to an embodiment of the present invention. As shown in FIG. 12, after receiving a ninth signal (including the first and fifth signals) transmitted by the network device, the forwarder receives a fifth signal transmitted to itself according to an instruction (e.g., a PDCCH, etc.), and then performs signal processing on at least the first signal to be transmitted (e.g., the entire ninth signal may be processed) before transmitting it to the terminal device. After receiving the transmission signal, the terminal device can obtain a second signal transmitted to itself according to an instruction (e.g., a PDCCH, etc.).

[0078] 13 is a diagram illustrating another example of a forwarder in an embodiment of the present invention. As shown in FIG. 13, the forwarder performs signal processing after receiving a ninth signal (including the first signal and the fifth signal) transmitted by the network device, and then obtains a fifth signal to be transmitted to itself based on an instruction (e.g., PDCCH, etc.), and can transmit at least the first signal for transmission to the terminal device. After receiving the transmission signal, the terminal device can obtain a second signal to be transmitted to itself based on an instruction (e.g., PDCCH, etc.).

[0079] In some embodiments, the sixth signal that the forwarder sends to the network device and the fourth signal that the forwarder forwards to the network device are included in the same signal that is sent to the network device.

[0080] For example, the time domain resources of the sixth signal and the time domain resources of the fourth signal are at least partially the same, the frequency domain resources of the sixth signal and the frequency domain resources of the fourth signal are different, and / or the code domain resources of the sixth signal and the code domain resources of the fourth signal are different. See Figure 9 or Figure 10 for examples where the time domain resources are at least partially the same.

[0081] Also, for example, the frequency domain resources of the sixth signal and the frequency domain resources of the fourth signal are at least partially the same, the time domain resources of the sixth signal and the time domain resources of the fourth signal are different, and / or the code domain resources of the sixth signal and the code domain resources of the fourth signal are different. See Figure 11 for an example where the frequency domain resources are at least partially the same.

[0082] In some embodiments, the sixth signal and the fourth signal within one time unit are orthogonal, and after receiving the same signal, the network device can use the orthogonality between the sixth signal and the fourth signal to derive the sixth signal and / or the fourth signal from the same signal.

[0083] For example, the time-frequency resource of the sixth signal and the time-frequency resource of the fourth signal are within one time unit, and the time unit is one of the following: a symbol, a slot, a subframe, a minislot, and a smallest scheduling unit not based on slot scheduling.

[0084] The time-frequency resources of the sixth signal are orthogonal to the time-frequency resources of the fourth signal, and / or the code-domain resources of the sixth signal are orthogonal to the code-domain resources of the fourth signal, and / or the sixth signal is orthogonal to the fourth signal in the spatial domain.

[0085] This allows the uplink communication signal that the forwarder sends to the network device and the uplink forwarded signal from the third device that is forwarded to the network device via the forwarder to be included in the same signal.

[0086] 14 is a diagram illustrating an example of a forwarder in an embodiment of the present invention. As shown in FIG. 14, the forwarder can receive a third signal transmitted from a terminal device, process the signal, and generate a fourth signal, and then generate a sixth signal by itself, and combine the fourth signal and the sixth signal into a single signal and then transmit it to a network device.

[0087] 15 is a diagram illustrating another example of a forwarder in an embodiment of the present invention. As shown in FIG. 15, the forwarder can receive a third signal transmitted from a terminal device, process the signal, and generate a fourth signal. The forwarder can process the signal itself to generate a sixth signal, and then combine the fourth and sixth signals into a single signal and transmit it to a network device.

[0088] Figures 12 and 14 exemplarily illustrate one implementation scheme of the signal merging of the forwarder, of which Figure 12 illustrates the downlink case and Figure 14 illustrates the uplink case. Figures 13 and 15 exemplarily illustrate another implementation scheme of the signal merging of the forwarder, of which Figure 13 illustrates the downlink case and Figure 15 illustrates the uplink case. Figures 12 to 15 exemplarily illustrate the forwarder in the embodiment of the present invention, but the present invention is not limited thereto.

[0089] 14 and 15, the third signal may be an RF signal, and the sixth signal may be a baseband signal, an intermediate frequency signal, or an RF signal. The transmitter may perform signal processing at baseband, RF, or an intermediate frequency to combine the third signal and the sixth signal. For example, when combining at baseband, the sixth signal output by the communication module may be a baseband signal; when combining at intermediate frequency, the sixth signal may be a baseband or intermediate frequency signal; and when combining at RF, the sixth signal may be a baseband, intermediate frequency, or RF signal.

[0090] In some embodiments, the seventh signal that the forwarder sends to the third device and the second signal that the network device sends to the third device via the forwarder are included in the same signal from the forwarder.

[0091] For example, the time domain resources of the seventh signal and the time domain resources of the second signal are at least partially the same, the frequency domain resources of the seventh signal and the frequency domain resources of the second signal are different, and / or the code domain resources of the seventh signal and the code domain resources of the second signal are different. See Figure 9 or Figure 10 for examples where the time domain resources are at least partially the same.

[0092] Also, for example, the frequency domain resources of the seventh signal and the frequency domain resources of the second signal are at least partially the same, the time domain resources of the seventh signal and the time domain resources of the second signal are different, and / or the code domain resources of the seventh signal and the code domain resources of the second signal are different. See Figure 11 for an example where the frequency domain resources are at least partially the same.

[0093] In some embodiments, the time-frequency resource of the seventh signal and the time-frequency resource of the second signal are within one time unit, and the time unit is one of the following: a symbol, a slot, a subframe, a minislot, and a smallest scheduling unit that is not based on slot scheduling.

[0094] The time-frequency resources of the seventh signal are orthogonal to the time-frequency resources of the second signal, and / or the code-domain resources of the seventh signal are orthogonal to the code-domain resources of the second signal, and / or the seventh signal and the second signal are orthogonal in the spatial domain.

[0095] In some embodiments, the eighth signal that the third device sends to the forwarder and the third signal that is forwarded to the network device via the forwarder are included in the same signal that is sent to the forwarder.

[0096] For example, the time domain resources of the eighth signal and the time domain resources of the third signal are at least partially the same, the frequency domain resources of the eighth signal and the frequency domain resources of the third signal are different, and / or the code domain resources of the eighth signal and the code domain resources of the third signal are different. See Figure 9 or Figure 10 for examples where the time domain resources are at least partially the same.

[0097] Also, for example, the frequency domain resources of the eighth signal and the frequency domain resources of the third signal are at least partially the same, the time domain resources of the eighth signal and the time domain resources of the third signal are different, and / or the code domain resources of the eighth signal and the code domain resources of the third signal are different. See Figure 11 for an example where the frequency domain resources are at least partially the same.

[0098] In some embodiments, the time-frequency resource of the eighth signal and the time-frequency resource of the third signal are within one time unit, and the time unit is one of the following: a symbol, a slot, a subframe, a minislot, and a smallest scheduling unit that is not based on slot scheduling.

[0099] The time-frequency resources of the eighth signal are orthogonal to the time-frequency resources of the third signal, and / or the code-domain resources of the eighth signal are orthogonal to the code-domain resources of the third signal, and / or the eighth signal and the third signal are orthogonal in the spatial domain.

[0100] 16 is a diagram illustrating an example of a forwarder in an embodiment of the present invention. As shown in FIG. 16, for example, after receiving a ninth signal (including the first signal and the fifth signal) transmitted by the network device, the forwarder obtains the fifth signal to be transmitted thereto based on an instruction (e.g., PDCCH, etc.), and then performs signal processing on at least the first signal to be transmitted (e.g., the entire ninth signal may be processed) before transmitting it to the terminal device. After receiving the transmission signal, the terminal device can obtain the second signal to be transmitted thereto based on an instruction (e.g., PDCCH, etc.).

[0101] Although FIG. 16 illustrates one case of downlink transmission as an example, other cases can be processed in the same manner.

[0102] For example, the forwarder may receive a third signal transmitted by the terminal device, process the signal, and generate a fourth signal; the forwarder may generate a sixth signal by itself, and then combine the fourth and sixth signals into the same signal before transmitting it to the network device.

[0103] Also, for example, the forwarder may receive a first signal transmitted by a network device and then process the signal to generate a second signal, and the forwarder may generate a seventh signal by itself, and then combine the second signal and the seventh signal into the same signal before transmitting it to the terminal device.

[0104] Also, for example, the forwarder can perform signal processing after receiving the tenth signal (including the third signal and the eighth signal) transmitted by the terminal device, and based on instructions, can obtain the eighth signal to be transmitted to itself, and can also perform signal processing on the third signal for forwarding and then forward it to the network device.

[0105] 17 is a diagram illustrating another example of a forwarder in an embodiment of the present invention. As shown in FIG. 17, for example, the forwarder can perform signal processing after receiving a ninth signal (including the first signal and the fifth signal) transmitted by the network device, and obtain a fifth signal to be transmitted to itself based on an instruction (e.g., PDCCH, etc.), and can signal process at least the first signal for transmission and then transmit it to the terminal device. After receiving the transmission signal, the terminal device can obtain a second signal to be transmitted to itself based on an instruction (e.g., PDCCH, etc.).

[0106] Although FIG. 17 illustrates one case of downlink transmission as an example, other cases can be processed in the same manner.

[0107] For example, the forwarder can receive a third signal transmitted by the terminal device, process the signal, and generate a fourth signal; the forwarder can generate a sixth signal by itself, and then combine the fourth and sixth signals into the same signal before transmitting it to the network device.

[0108] Also, for example, the forwarder can receive a first signal transmitted by a network device, process the signal, and generate a second signal; the forwarder can generate a seventh signal by itself, and then combine the second and seventh signals into the same signal before transmitting it to the terminal device.

[0109] Also, for example, the forwarder can perform signal processing after receiving the tenth signal (including the third signal and the eighth signal) transmitted by the terminal device, obtain the eighth signal transmitted to itself based on the instruction, and then perform signal processing on the third signal for forwarding before forwarding it to the network device.

[0110] Although the signal merging scheme has been described above, the present invention is not limited thereto, and the following describes a time division scheme, in which the communication signal and the transport signal may be time division multiplexed (TDM), but the present invention is not limited thereto.

[0111] In some embodiments, the fifth signal that the network device sends to the forwarder and the first signal that the network device sends to the third device via the forwarder are in different time units, and the sixth signal that the forwarder sends to the network device and the fourth signal that the forwarder forwards to the network device are in different time units.

[0112] For example, the network device transmitting a downlink communication signal to the forwarder and the forwarder transmitting a downlink transport signal between the network device and the terminal device are time-division, i.e., occur at different times. Also, for example, the forwarder transmitting an uplink communication signal to the network device and the forwarder forwarding an uplink transport signal between the network device and the terminal device are time-division, i.e., occur at different times.

[0113] In some embodiments, the second signal that the forwarder forwards to the third device and the third signal that the forwarder forwards to the network device are within different time units, and the fifth signal that the network device sends to the forwarder and the sixth signal that the forwarder sends to the network device are within different time units.

[0114] For example, the forwarding of downlink transport signals between the network device and the terminal device by the forwarder and the forwarding of uplink transport signals between the network device and the terminal device by the forwarder are time-division, i.e., occur at different times. Also, for example, the transmission of downlink communication signals from the network device to the forwarder and the transmission of uplink communication signals from the forwarder to the network device are time-division, i.e., occur at different times.

[0115] Also, for example, the transmission of downlink communication signals from the network device to the forwarder, the forwarding of downlink transport signals between the network device and the terminal device by the forwarder, the transmission of uplink communication signals from the forwarder to the network device, and the forwarding of uplink transport signals between the network device and the terminal device by the forwarder are all time-division, i.e., occur at different times.

[0116] 18 is a diagram illustrating an example of a forwarder in an embodiment of the present invention. As shown in FIG. 18, the forwarder forwards a signal from a network device to a terminal device. That is, the forwarder receives a first signal from the network device, processes the first signal to generate a second signal, and then transmits the second signal to the terminal device. At this time, the forwarder forwards the signal but does not communicate with the network device or demodulate / decode the first signal.

[0117] 19 is a diagram illustrating another example of a forwarder in an embodiment of the present invention. As shown in FIG. 19, the forwarder forwards a signal from a terminal device to a network device. That is, the forwarder receives a third signal from the terminal device, processes the third signal to generate a fourth signal, and then transmits the fourth signal to the network device. At this time, the forwarder forwards the signal but does not communicate with the network device or demodulate / decode the third signal.

[0118] 20 is a diagram illustrating an example of a forwarder according to an embodiment of the present invention. As shown in FIG. 20, the forwarder does not forward a signal but communicates with a network device. That is, the forwarder receives a fifth signal from the network device and demodulates / decodes the fifth signal.

[0119] 21 is a diagram illustrating an example of a forwarder in an embodiment of the present invention. As shown in FIG. 21, the forwarder does not forward a signal but communicates with a network device. That is, the forwarder generates a sixth signal and sends the sixth signal to the network device.

[0120] 18 to 21 exemplarily show one realization scheme of time division of the transmitter, and show the case of time division for downlink transmission signal, uplink transmission signal, downlink communication signal, and uplink communication signal, respectively. Although FIG. 18 to 21 exemplarily illustrate only the transmitter in the embodiment of the present invention, the present invention is not limited thereto.

[0121] For example, based on Figures 18 to 21, communication between the transferor and the terminal device may be time-shared with transfer between the transferor and the terminal device, and may also be time-shared with communication or transfer between the transferor and the network device.

[0122] In some embodiments, the seventh signal that the forwarder sends to the third device and the second signal that the network device sends to the third device via the forwarder are in different time units, and the eighth signal that the third device sends to the forwarder and the third signal forwarded to the network device via the forwarder are in different time units.

[0123] For example, the second signal forwarded by the forwarder to the terminal device and the third signal forwarded by the forwarder to the network device are in different time units, and / or the seventh signal sent by the forwarder to the terminal device and the eighth signal sent via the forwarder to the network device are in different time units.

[0124] In some embodiments, the fifth signal sent by the network device to the forwarder and the first signal sent by the network device to the third device via the forwarder are included in the ninth signal, and the ninth signal, the sixth signal sent by the forwarder to the network device, and the fourth signal forwarded by the forwarder to the network device are within different time units.

[0125] For example, the transmission of downlink communication signals from the network device to the forwarder and the forwarding of downlink transport signals between the network device and the terminal device by the forwarder may be included in the same signal, and the transmission of that same signal from the network device to the forwarder, the transmission of uplink communication signals from the forwarder to the network device, and the forwarding of uplink transport signals between the network device and the terminal device by the forwarder may be time-shared, i.e., occur at different times. Also, for example, the forwarding of downlink transport signals between the network device and the terminal device by the forwarder and the forwarding of uplink transport signals between the network device and the terminal device by the forwarder may be time-shared, i.e., occur at different times.

[0126] 22 is a diagram illustrating an example of a forwarder according to an embodiment of the present invention. As shown in FIG. 22, the forwarder receives a ninth signal (including a first signal and a fifth signal) from a network device. The forwarder processes the ninth signal to obtain a fifth signal. The forwarder can further perform signal processing on at least the first signal in the ninth signal (or process the entire ninth signal) to generate a second signal, and then transmit the second signal to the terminal device.

[0127] Figure 22 shows another implementation scheme of time division of the transmitter, in which the downlink transport signal and the downlink communication signal are included in the same signal, and the description of the uplink transport signal and the uplink communication signal is omitted here, and reference can be made to Figures 19 and 21. Figure 22 only describes the transmitter in the embodiment of the present invention, but the present invention is not limited thereto.

[0128] In some embodiments, the eighth signal that the third device sends to the forwarder and the third signal that the third device sends to the network device via the forwarder are included in the tenth signal, and the tenth signal, the seventh signal that the forwarder sends to the third device, and the second signal forwarded to the third device via the forwarder are within different time units.

[0129] 23 is a diagram illustrating an example of a forwarder according to an embodiment of the present invention. As shown in FIG. 23, the forwarder receives a tenth signal (including a third signal and an eighth signal) from a terminal device. The forwarder processes the tenth signal to obtain an eighth signal. The forwarder further processes at least the third signal in the tenth signal (or may process the entire tenth signal) to generate a fourth signal, and then transmits the fourth signal to a network device.

[0130] 24 is a diagram illustrating another example of a forwarder in an embodiment of the present invention. As shown in FIG. 24, the forwarder receives a ninth signal (including a first signal and a fifth signal) from a network device. The forwarder processes the ninth signal to obtain a fifth signal. The forwarder processes at least the first signal in the ninth signal to generate a second signal, and then transmits the second signal to the terminal device.

[0131] 25 illustrates another example of a forwarder in an embodiment of the present invention. As shown in FIG. 25, the forwarder does not forward a signal but communicates with the network device. That is, the forwarder generates a sixth signal and sends the sixth signal to the network device.

[0132] 26 is a diagram illustrating another example of a forwarder transmitting a downlink signal in an embodiment of the present invention. As shown in FIG. 26, the forwarder does not forward a signal but communicates with the terminal device. That is, the forwarder generates a seventh signal and transmits the seventh signal to the network device.

[0133] 27 illustrates another example of a forwarder in an embodiment of the present invention. As shown in FIG. 27, the forwarder does not forward signals but communicates with the terminal device and the network device. That is, the forwarder generates a sixth signal and sends the sixth signal to the network device, and the forwarder generates a seventh signal and sends the seventh signal to the network device.

[0134] 28 is a diagram illustrating another example of a forwarder in an embodiment of the present invention. As shown in FIG. 28, the forwarder receives a tenth signal (including a third signal and an eighth signal) from a terminal device. The forwarder processes the tenth signal to obtain an eighth signal. The forwarder processes at least the third signal in the tenth signal to generate a fourth signal, and sends the fourth signal to a network device.

[0135] 29 is a diagram illustrating another example of a forwarder in an embodiment of the present invention. As shown in FIG. 29, the forwarder receives a third signal from a terminal device. The forwarder processes the third signal to generate a fourth signal, and transmits the fourth signal to a network device.

[0136] Although the time division scheme has been described above as an example, the present invention is not limited thereto, and the frequency division scheme (also referred to as a different frequency scheme) will be further described below. The different frequencies refer to the use of different frequency resources, such as the use of different frequency bands (Frequency Bands / Frequency Ranges) or frequency points, or the use of different carriers (Carriers) or bandwidth fractions (BWPs).

[0137] In some embodiments, the forwarder communicates with the network device over a first frequency resource and forwards signals routed through the forwarder over a second frequency resource, the first frequency resource and the second frequency resource not overlapping in the frequency domain.

[0138] For example, the forwarder receives a fifth signal transmitted by the network device over the first frequency resource and transmits a sixth signal to the network device over the first frequency resource, i.e., communication between the network device and the forwarder utilizes a frequency point or frequency band, such as FR1.

[0139] For example, the forwarder receives a first signal for forwarding on a second frequency resource and forwards a second signal to the terminal device on the second frequency resource, the forwarder receives a third signal for forwarding on the second frequency resource and forwards a fourth signal to the network device on the second frequency resource, that is, the forwarding between the network device and the terminal device uses another frequency point or frequency band, such as FR2.

[0140] Figure 30 illustrates another example of a forwarder in an embodiment of the present invention, showing one implementation scheme for different frequencies of the forwarder. As shown in Figure 30, the frequency resource used by the communication module of the forwarder (communicating with the network device) is different from the frequency resource used by the forwarding module of the forwarder (for forwarding signals between the network device and the terminal device).

[0141] In some embodiments, the forwarder receives a fifth signal transmitted by the network device on a third frequency resource and transmits a sixth signal to the network device on a fourth frequency resource, the third frequency resource and the fourth frequency resource being within the first frequency resource.

[0142] The forwarder receives a first signal for forwarding on the second frequency resource and forwards a second signal to a third device on the second frequency resource, and the forwarder receives a third signal for forwarding on the second frequency resource and forwards a fourth signal to the network device on the second frequency resource.

[0143] For example, communication between the forwarder and the network device may be frequency division duplexed (FDD).

[0144] Figure 31 illustrates another example of a forwarder in an embodiment of the present invention, showing another implementation scheme for different frequencies of the forwarder. As shown in Figure 31, the frequency resource (first frequency resource) used by the communication module of the forwarder (communicating with the network device) is different from the frequency resource (second frequency resource) used by the forwarding module of the forwarder (transmitting signals between the network device and the terminal device). Also, as shown in Figure 31, the frequency resource (third frequency resource) used by the communication module of the forwarder for downlink communication is different from the frequency resource (fourth frequency resource) used by the communication module of the forwarder for uplink communication.

[0145] In some embodiments, the forwarder transmits a sixth signal to the network device on a first frequency resource, receives a fifth signal transmitted by the network device on a second frequency resource, and forwards the forwarded signal via the forwarder on the second frequency resource, wherein the first frequency resource and the second frequency resource do not overlap in the frequency domain.

[0146] The forwarder receives a first signal for forwarding on the second frequency resource and forwards a second signal to a third device on the second frequency resource, and the forwarder receives a third signal for forwarding on the second frequency resource and forwards a fourth signal to the network device on the second frequency resource.

[0147] For example, uplink communication between the network device and the forwarder uses one frequency point or frequency band, e.g., FR1, and downlink communication between the network device and the terminal device and between the network device and the forwarder uses another frequency point or frequency band, e.g., FR2.

[0148] Figure 32 illustrates another example of a forwarder in an embodiment of the present invention, showing another implementation scheme for different frequencies of the forwarder. As shown in Figure 32, the frequency resources used for uplink transmission of the communication module of the forwarder (communicating with the network device) are different from the frequency resources used for downlink transmission of the forwarding module of the forwarder (transmitting signals between the network device and the terminal device) and the communication module.

[0149] Figure 33 illustrates another example of a forwarder in an embodiment of the present invention, illustrating another implementation scheme for different frequencies of the forwarder. As shown in Figure 33, the frequency resource used by the communication module of the forwarder (communicating with the network device and / or the terminal device) is different from the frequency resource used by the forwarding module of the forwarder (for forwarding signals between the network device and the terminal device).

[0150] Also, as shown in Figure 33, the signal transmitted by the terminal device to the forwarder and the signal transmitted to the network device via the forwarder can be merged, and the uplink transmission, downlink communication transmission, and downlink forwarding transmission between the forwarder and the terminal device may be time-division.

[0151] Figure 34 illustrates another example of a forwarder in an embodiment of the present invention, and exemplarily illustrates another implementation scheme for different frequencies of the forwarder. As shown in Figure 34, the frequency resource used by the communication module of the forwarder (communicating with the network device and / or the terminal device) is different from the frequency resource used by the forwarding module of the forwarder (for forwarding signals between the network device and the terminal device).

[0152] Also, as shown in FIG. 34, the signal transmitted from the forwarder to the terminal device and the signal transmitted to the terminal device via the forwarder can be merged, the signal transmitted from the terminal device to the forwarder and the signal transmitted to the network device via the forwarder can be merged, and the downlink transmission and the uplink communication transmission between the forwarder and the terminal device may be time-division.

[0153] Although the frequency division scheme has been described above as an example, the present invention is not so limited.

[0154] Furthermore, although only the steps or processes according to the present invention have been described above, the present invention is not limited thereto, and the method in the embodiments of the present invention may further include other steps or processes, and reference can be made to the related art for the specific content of these steps or processes.

[0155] Furthermore, the above-described embodiments are merely illustrative of the present invention, and the present invention is not limited thereto. Appropriate modifications may be made based on the above-described embodiments. For example, each of the above-described embodiments may be used alone, or a combination of two or more of the above-described embodiments may be used.

[0156] According to an embodiment of the present invention, the forwarder can forward signals through predefined beams or beams instructed or configured by the network device, thereby achieving better signal coverage and reducing interference to other surrounding devices, thereby improving the transmission efficiency of the entire network.

[0157] <Example of the second aspect> In an embodiment of the present invention, a forwarder is provided, which may be, for example, a network device or a terminal device, or may be one or more components or assemblies provided in the network device or the terminal device.

[0158] 35 is a diagram illustrating a transmitter according to an embodiment of the present invention. The principle by which the transmitter solves the problem is the same as the method in the embodiment of the first aspect, so that specific implementations can refer to the embodiment of the first aspect, and redundant explanations of the same content will be omitted here.

[0159] As shown in Figure 35, the forwarder 3500 in this embodiment of the present invention includes a forwarding module 3501, which is used to perform forwarding in the RF domain. As shown in Figure 35, the forwarder 3500 may further include a communication module 3502, which is used to communicate with a network device.

[0160] In some embodiments, the forwarding module 3501 forwards signals from the network device using a predefined beam or a beam directed or configured by the network device, and / or forwards signals to the network device using a predefined beam or a beam directed or configured by the network device.
