Description

[Technical Field]

[0001] FIELD OF THE INVENTION Embodiments of the present invention relate to the field of communications technology. [Background technology]

[0002] Compared with the conventional 3G (third generation mobile communication technology) and 4G (fourth generation mobile communication technology) systems, the 5G (fifth generation mobile communication technology) system provides wider bandwidth and higher data rates, and can support more types of terminals and diverse industrial services.

[0003] As such, 5G systems are being deployed in traditional telecommunications spectrum as well as new spectrum that has significantly higher frequencies than the traditional telecommunications spectrum used by 3G and 4G systems. For example, 5G systems may be deployed in millimeter wave bands (e.g., 28 GHz, 38 GHz, 60 GHz and above).

[0004] According to the radio signal propagation rules, the higher the frequency of the carrier wave on which the radio signal is located, the greater the signal fading during propagation. Therefore, in actual deployment, how to enhance cell coverage of the 5G system compared to traditional 3G and 4G systems, especially for 5G systems deployed in the millimeter wave band, is one of the problems that needs to be solved urgently.

[0005] Meanwhile, compared with traditional 3G and 4G systems, 5G systems adopt more advanced multi-antenna propagation technology and corresponding transmission equipment. To support more flexible and complex services, the complexity of 5G systems is higher than that of 3G and 4G systems. Accordingly, the power consumption of 5G systems is also higher than that of 3G and 4G systems. How to reduce the power consumption of 5G systems and save energy costs is also one of the issues that needs to be resolved urgently.

[0006] The above description of the background art is merely for the purpose of explaining the configuration of the present invention more clearly and completely, and is provided for the understanding of those skilled in the art. These configurations described in the background art of the present invention should not be construed as being well known to those skilled in the art. Summary of the Invention [Problem to be solved by the invention]

[0007] In view of at least one of the above problems, an embodiment of the present invention provides a repeater instruction method, a repeater, and a network device. The repeater has the ability to communicate with network devices, and when deployed in a network, it can better enhance signal coverage and adapt to environmental changes (e.g., reduce interference to other network devices and terminal devices during transmission), and also reduce system power consumption and save energy costs. [Means for solving the problem]

[0008] In one aspect of an embodiment of the present invention, a method for instructing a repeater includes the steps of: receiving configuration information from a network device by the repeater, the configuration information configuring / instructing at least a first resource, a second resource, and / or a third resource; the repeater performing forwarding on the first resource and / or not performing forwarding on the second resource based on the configuration information.

[0009] Another aspect of an embodiment of the present invention provides a repeater including: a receiver that receives configuration information from a network device, the configuration information configuring / instructing at least a first resource and / or a second resource and / or a third resource; and a controller that performs forwarding in the first resource and / or does not perform forwarding in the second resource based on the configuration information.

[0010] Another aspect of an embodiment of the present invention provides a repeater instruction method, comprising: a step of a network device sending configuration information to a repeater, the configuration information configuring / instructing at least a first resource and / or a second resource and / or a third resource, and the configuration information being used by the repeater to determine to perform forwarding on the first resource and / or not to perform forwarding on the second resource.

[0011] Another aspect of an embodiment of the present invention provides a network device including a transmitter that transmits configuration information to a repeater, the configuration information configuring / indicating at least a first resource and / or a second resource and / or a third resource, and the configuration information being used by the repeater to determine whether to perform forwarding on the first resource and / or not to perform forwarding on the second resource.

[0012] Another aspect of an embodiment of the present invention provides a communication system including a repeater that receives configuration information from a network device, the configuration information configuring / instructing at least a first resource, a second resource, and / or a third resource, and that performs forwarding on the first resource and / or does not perform forwarding on the second resource based on the configuration information, and the network device that transmits the configuration information to the repeater.

[0013] One of the advantageous effects of the embodiment of the present invention is that a repeater receives configuration information from a network device, and the configuration information configures / instructs at least a first resource, a second resource, and / or a third resource, so that the repeater can perform forwarding or not perform forwarding according to the configuration information, thereby reducing unnecessary interference and improving the transmission efficiency of the entire network.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The above and other features of the present invention will become apparent from the following description. In the specification and drawings, specific embodiments of the present invention are disclosed in detail, and some of the embodiments in which the principles of the present invention can be adopted are shown. However, the present invention is not limited to the described embodiments. The present invention includes all modifications, variations, and equivalents within the scope of the appended claims. Below, various embodiments of the present invention will be described with reference to the drawings. These embodiments are merely illustrative and do not limit the present invention.

[0020] In embodiments of the present invention, the terms "first," "second," etc. are used in titles to distinguish between different elements, but do not represent the spatial arrangement or temporal order of these elements, and these elements are not limited to these terms. The term "and / or" includes any and all combinations of one or more of the terms listed in the associated list. The terms "comprise," "include," "have," etc. refer to the presence of listed features, elements, elements, or components, but do not exclude the presence or addition of one or more other features, elements, elements, or components.

[0021] In the embodiments of the present invention, the singular forms "one," "the," etc., include the plural and should be understood broadly as "one kind" or "one class," and are not limited to "one." Furthermore, the term "said" should be understood to include both the singular and the plural, unless the context clearly indicates otherwise. Furthermore, the term "described in" should be understood to mean "described at least in part," and the term "based on" should be understood to mean "based at least in part," unless the context clearly indicates otherwise.

[0022] In embodiments of the present invention, the terms "communication network" or "wireless communication network" may refer to a network conforming to any communication standard, such as, for example, Long Term Evolution (LTE), Long Term Evolution Advanced (LTE-A, LTE-Advanced), Wideband Code Division Multiple Access (WCDMA), High-Speed ​​Packet Access (HSPA), etc.

[0023] Additionally, communications between devices in a communications system may occur according to any stage of communications protocol, including, but not limited to, 1G (generation), 2G, 2.5G, 2.75G, 3G, 4G, 4.5G, and 5G, New Radio (NR), and / or other currently known or future developed communications protocols.

[0024] In an embodiment of the present invention, the term "network device" refers to a device in a communication system that allows a terminal device to access the communication system and provides a service to the terminal device, and may include, but is not limited to, a base station (BS), an access point (AP), a transmission reception point (TRP), a broadcast transmitter, a mobility management entity (MME), a gateway, a server, a radio network controller (RNC), a base station controller (BSC), etc.

[0025] Among them, the base station may include, but is not limited to, a Node B (NodeB or NB), an evolved Node B (eNodeB or eNB), a 5G base station (gNB), an IAB donor, etc., as well as a remote radio head (RRH), a remote radio unit (RRU), a relay, or a low-power node (e.g., femto, pico, etc.). The term "base station" may include some or all of these functions, and each base station may provide communication coverage for a particular geographic area. The term "cell" may refer to a base station and / or its coverage area, depending on the context in which the term is used.

[0026] In the embodiments of the present invention, the term "User Equipment" (UE) or "Terminal Equipment" (TE) refers to a device that connects to a communication network via, for example, a network device and receives network services. The terminal device may be fixed or mobile, and may also be referred to as a mobile station (MS), a terminal, a subscriber station (SS), an access terminal (AT), a station, etc.

[0027] Among them, the terminal device may include, but is not limited to, a mobile phone, a personal digital assistant (PDA), a wireless modulation / demodulation device, a wireless communication device, a handheld device, a machine-type communication device, a laptop computer, a cordless phone, a smartphone, a smart watch, a digital camera, etc.

[0028] Furthermore, for example, in a scenario such as the Internet of Things (IoT), the user device may be a monitoring or measurement device or apparatus, including, but not limited to, a Machine Type Communication (MTC) terminal, an in-vehicle communication terminal, an industrial wireless device, a surveillance camera, a Device to Device (D2D) terminal, a Machine to Machine (M2M) terminal, etc.

[0029] To further enhance coverage, 3GPP Rel-17 studies introduce an RF repeater to forward transmissions between a user equipment (UE) and a network device (base station). The RF repeater introduced in Rel-17 is transparent to the network device and the user equipment, i.e., the network device and the user equipment are unaware of the existence of the RF repeater.

[0030] 1 is a schematic diagram of an example of an application scenario of an embodiment of the present invention. As shown in FIG. 1, for convenience of explanation, one network device (for example, a 5G base station gNB) 101, one repeater 102, and one user equipment (UE) 103 are described as an example, but the present invention is not limited thereto.

[0031] As shown in Fig. 1, a terminal device 103 establishes a connection and communicates with a network device 101. To improve communication quality, a channel / signal transmitted between the terminal device 103 and the network device 101 is forwarded via a repeater 102. The interaction of the channel / signal between the network device 101, the terminal device 103, and the repeater 102 all adopts a beam-based receiving and transmitting method. The beam may be a fixed beam or an adaptive beam.

[0032] 1, the network device 101 may have a cell / carrier, and the network device 101, the repeater 102, and the terminal device 103 can perform transmission / communication in the cell. However, the present invention is not limited thereto, and for example, the network device 101 may have another cell / carrier.

[0033] In an embodiment of the present invention, existing or future services can be performed between a network device and a terminal device, for example, these services may include, but are not limited to, enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), highly reliable and low latency communications (URLLC), and vehicle-to-everything (V2X) communications.

[0034] Because a conventional repeater does not have the ability to communicate with a network device, although the conventional repeater can strengthen the signal strength, it does not have enough flexibility to respond to complex environmental changes. Therefore, when a conventional repeater is deployed in a 5G network (especially a high-frequency 5G network), it may cause unnecessary interference to other network devices and / or terminal devices, and may reduce the transmission efficiency (e.g., throughput) of the entire network. In order to make the forwarding of the conventional repeater more flexible to adapt to the characteristics of the 5G network, the network device needs to support the repeater and configure the forwarding of the repeater according to the network situation.

[0035] To enhance the coverage of 3GPP Rel-18 NR, a network-controlled repeater (NCR) is proposed to forward signals between network devices and terminal devices. To support the forwarding operation of the NCR, the NCR can directly communicate with the network device via a control link.

[0036] 2 is a schematic diagram of an example of an NCR according to an embodiment of the present invention. As shown in FIG. 2, an NCR 202 is configured between a network device 201 and a terminal device 203. The NCR 202 may include two modules / components: a repeater mobile terminal (NCR-MT) and a repeater forwarding module (NCR-Fwd). The NCR-Fwd is also referred to as an NCR-RU routing unit (NCR-RU). The NCR-MT is used to communicate with the network device, and the NCR-Fwd is used to forward signals between the network device and the terminal device.

[0037] As shown in Fig. 2, the NCR of the embodiment of the present invention may have three links: a control link (C-link), a backhaul link (BH link) for forwarding, and an access link (AC link). Here, the C-link is used for communication between the NCR and the network device. The BH link is used by the repeater to receive signals to be forwarded from the network device or to forward signals from the AC link (e.g., from a terminal device) to the network device. The AC link is used by the repeater to forward signals from the network device (e.g., to a terminal device) or to receive signals to be forwarded to the BH link (e.g., from a terminal device).

[0038] According to the inventors' recognition, the 5G system is more complex than the conventional 3G, 4G systems, etc., and needs to support more types of services and terminal types, and also needs to be deployed in various frequency bands and scenarios, etc. Compared with the conventional RF repeater, the NCR needs to have a beam-based function.

[0039] Fig. 3 is a schematic diagram of an example of NCR forwarding according to an embodiment of the present invention. As shown in Fig. 3, the repeater forwards a signal from a network device using a transmit beam on an AC link. Fig. 4 is a schematic diagram of another example of NCR forwarding according to an embodiment of the present invention. As shown in Fig. 4, the repeater receives a signal for forwarding to a network device using a receive beam on an AC link.

[0040] Various aspects of the embodiments of the present invention will be described below with reference to the drawings. These aspects are merely exemplary and do not limit the present invention. A repeater according to the embodiments of the present invention may operate in a first frequency range (FR1), may operate in a second frequency range (FR2), or may operate in both the first frequency range (FR1) and the second frequency range (FR2). For specific details of FR1 and FR2, please refer to the related art.

[0041] In an embodiment of the present invention, a repeater can communicate with a network device, and the repeater can receive a communication channel / signal transmitted by the network device and obtain information transmitted from the network device to the repeater by demodulating / decoding the channel / signal. This signal processing process is hereinafter referred to as "communication." The repeater can forward a channel / signal transmitted between a network device and a terminal device, and the repeater can amplify or process the channel / signal without demodulating / decoding it. This signal processing process is hereinafter referred to as "forwarding." "Communication" and "forwarding" are collectively referred to as "transmission." Furthermore, "performing transmission or reception over an AC link" may be equivalent to "performing forwarding over an AC link," and "performing transmission or reception over a control link" may be equivalent to "performing communication over a control link." The above terms are used for convenience of explanation and do not limit the present invention.

[0042] For convenience of explanation, a channel / signal for direct communication between a network device and a repeater, or between a third device (e.g., a terminal device) and a repeater, may be referred to as a communication signal. When transmitting a communication signal, the repeater needs to perform encoding and / or modulation, and when receiving a communication signal, the repeater needs to perform decoding and / or demodulation. Also, a channel / signal forwarded via a repeater may be referred to as a transport signal. The repeater may perform signal processing such as amplification on the forwarded signal, but does not perform decoding and / or demodulation.

[0043] In an embodiment of the present invention, a repeater may be expressed as a repeater, radio frequency repeater, forwarder, radio frequency forwarder, or as a repeater node, repeater node, forwarder node, or as a smart repeater, smart repeater, smart forwarder, smart repeater node, smart repeater node, smart forwarder node, etc., but the present invention is not limited thereto.

[0044] In the embodiments of the present invention, the network device may be a device of a serving cell of a terminal device, a device of a cell in which a repeater is located, a device of a serving cell of a repeater, or a parent node of a repeater. The present invention is not limited to the name of the repeater, and any device capable of realizing the above functions is included in the scope of the repeater according to the present invention.

[0045] In an embodiment of the present invention, a beam may be represented as a reference signal (RS), a transmission configuration indication (TCI), a spatial domain filter, etc., or may be represented as a beam index, a reference signal index, a transmission configuration indication index, a spatial domain filter index, etc. The above reference signal may be, for example, a channel state information reference signal (CSI-RS), a sounding reference signal (SRS), an RS for a repeater, an RS transmitted by a repeater, etc. The above TCI may be represented as a TCI state. The embodiment of the present invention is not limited thereto.

[0046] Example 1 The embodiment of the present invention provides a repeater indication method and is explained from the repeater side.

[0047] 5 is a schematic diagram of an example of a repeater instruction method according to an embodiment of the present invention. As shown in FIG. 5, the method includes the following steps:

[0048] Step 501: A repeater receives configuration information from a network device, the configuration information configuring / indicating at least a first resource and / or a second resource and / or a third resource.

[0049] Step 502: The repeater performs forwarding in the first resource and / or does not perform forwarding in the second resource based on the configuration information.

[0050] It should be noted that the above-mentioned FIG. 5 merely illustrates an example of the present invention, and the present invention is not limited thereto. For example, the execution order of various steps may be appropriately adjusted, some other steps may be added, or some steps may be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description of the above-mentioned FIG. 5.

[0051] In an embodiment of the present invention, at least a portion of the first resource, the second resource, and / or the third resource may be configured and / or indicated by configuration information, and / or at least a portion of the first resource, the second resource, and / or the third resource may be predefined or predetermined according to a rule. The present invention is not limited thereto, and for example, all resources may be configured and / or indicated by configuration information, or all resources may be predefined or predetermined according to a rule.

[0052] In some embodiments, the network device may configure at least two of a first resource, a second resource, and a third resource for the repeater. The first resource may be used for forwarding and may be a resource available for forwarding (e.g., referred to as a hard resource or an ON resource), the second resource may be a resource not used for forwarding and unavailable for forwarding (e.g., referred to as a NA resource or an OFF resource), and the third resource may be used for forwarding and may be a resource not yet determined for forwarding (e.g., referred to as a flexible resource or a soft resource). The present invention is not limited thereto.

[0053] For example, a network device may support a first resource, a second resource, and a third resource and configure the three resources for a repeater at configuration time. As another example, a network device may support the first resource, the second resource, and the third resource, but configure at least two of them for a repeater at configuration time. As another example, a network device may support two of the first resource, the second resource, and the third resource, and configure one or both of the resources for a repeater at configuration time. The present invention is not limited to the above aspects.

[0054] In some embodiments, the repeater is in an ON state, an available state, or a hard state on the first resource. For example, the ON state is a standby state or a state capable of performing forwarding. The standby state is a state that is default OFF and capable of performing forwarding when an instruction is received. As another example, the repeater may or may not be in a forwarding state, and if not in a forwarding state, may quickly transition to a forwarding state. As another example, the ON state is a state in which forwarding is performed. The repeater performs forwarding on the first resource.

[0055] In some embodiments, when a beam configuration is present (e.g., the repeater's operating frequency band is FR2), a beam for transmission is configured for at least some of the first resources, e.g., a corresponding beam is configured for at least some of the first resources of the repeater, and the repeater performs transmission using the corresponding beam for at least some of the first resources.

[0056] In some embodiments, when a beam configuration is not available for forwarding (e.g., the repeater's operating frequency band is FR1), a default beam and / or a fixed beam are used for forwarding. For example, at least a portion of the repeater's first resources correspond to the default beam and / or the fixed beam. The repeater performs forwarding using the default beam and / or the fixed beam in at least a portion of the first resources.

[0057] In some embodiments, when a beam configuration is present in a state in which transmission is performed (e.g., the repeater's operating frequency band is FR2), a corresponding beam is configured for each of the first resources of the repeater, and the repeater performs transmission using the corresponding beam in the first resource.

[0058] In some embodiments, when there is no beam configuration (e.g., the repeater's operating frequency band is FR1) in a state where forwarding is performed, all of the first resources of the repeater correspond to the default beam and / or the fixed beam, and the repeater performs forwarding using the default beam and / or the fixed beam in the first resources.

[0059] In the above description, "capable of performing forwarding" may mean that the repeater has the ability to perform forwarding and / or that the repeater is capable of performing forwarding on a first resource, but the first resource is not necessarily actually used for forwarding. "Performing forwarding" may mean that the repeater is instructed to perform forwarding, or that the repeater performs a forwarding operation, or that the repeater is capable of performing forwarding on a first resource, and / or that the first resource is actually used for forwarding. The above description is merely for the purpose of clarifying forwarding and is not intended to limit the present invention.

[0060] Also, in the context of the present invention, the terms "on state", "off state", "available state", "unavailable state", "hard state", "soft state", "flexible state", etc. may refer to a repeater, i.e., a repeater may have these states, or may refer to a resource, i.e., a resource may have these states. The specific meanings of the above terms in the context of the present invention will be understood by those skilled in the art.

[0061] In some embodiments, one time unit of the first resource corresponds to a transmission beam. For example, each time unit corresponds to a transmission beam. Also, for example, at least some of the time units correspond to a beam. The time unit may be one or any combination of a slot, a symbol, a subframe, or a mini-slot, but the present invention is not limited thereto.

[0062] For example, the transmission beam may be configured or instructed by the network equipment, or may be determined according to standard predefined rules, or may be pre-set (eg, prior to shipping).

[0063] In some embodiments, the repeater uses a transmission beam in the ON state corresponding to the first resource, for example, the transmission beam is a beam in a backhaul (BH) link and / or a beam in an access (AC) link.

[0064] For example, the repeater receives communication signals from the network device using a beam on the backhaul (BH) link, and / or the repeater transmits communication signals to the network device using a beam on the backhaul (BH) link.

[0065] For example, the repeater receives a transmission signal from a network device using a beam on an access (AC) link, and / or the repeater transmits a transmission signal to a network device using a beam on an access (AC) link.

[0066] In some embodiments, the transmission beam corresponding to some or all of the first resources is configured by semi-static signaling, such as radio resource control (RRC) signaling, MAC CE, etc.

[0067] In some embodiments, the first resource and / or the transmission beam are configured by semi-static signaling. The first resource and the transmission beam may be configured by the same signaling, or the first resource and the transmission beam may be configured by different signaling.

[0068] In some embodiments, the first resource has the highest priority.

[0069] In some embodiments, the beam direction of the first resource can only be reconfigured and cannot be overridden.

[0070] For example, if a first resource is configured by semi-static signaling as a hard resource (ON resource), the first resource may be reconfigured by other identical semi-static signaling as a soft resource (flexible resource) or an unavailable resource (OFF resource), or in a cancelled / erased / removed state.

[0071] As another example, if a transmission beam corresponding to a first resource is configured and / or indicated by semi-static signaling, the transmission beam may be reconfigured as the same transmission beam by another identical semi-static signaling, or the transmission beam may be reconfigured as a different transmission beam by another identical semi-static signaling, or the transmission beam may be cancelled / erased / removed by another identical semi-static signaling. Preferably, the transmission beam must not be overridden by another signaling (e.g., a DCI signaling or another semi-static signaling). That is, the repeater does not expect to receive another signaling indicating and / or configuring another transmission beam for the first resource, and / or the network device does not send to the repeater another signaling indicating and / or configuring another transmission beam for the first resource.

[0072] In some embodiments, the network device indicates a first resource via the first signaling and configures a first beam for the first resource via the second signaling.

[0073] In some embodiments, the first signaling indicates at least one or any combination of a start position, an offset, a period, or an end position of the first resource, although the invention is not limited thereto and the first signaling may indicate other attributes of the first resource.

[0074] In some embodiments, the second signaling indicates the first beam and / or the second signaling indicates time domain resources corresponding to the first beam.

[0075] For example, the second signaling may directly indicate the first beam, may directly indicate the time domain resources corresponding to the first beam, or may indicate both the first beam and the time domain resources corresponding to the first beam.

[0076] In some embodiments, the first resource partially overlaps with the time domain resource corresponding to the first beam, or the first resource completely overlaps (overlaps) with the time domain resource corresponding to the first beam, or the first resource includes at least the time domain resource corresponding to the first beam.

[0077] In some embodiments, the first resource can be reconfigured by other first signaling. For example, if a first resource is configured as a hard resource (ON resource) by semi-static signaling (RRC signaling), it may be reconfigured as a soft resource (flexible resource) or an unavailable resource (OFF resource) or a hard resource (ON resource) by other identical semi-static signaling (RRC signaling).

[0078] In some embodiments, the first beam can only be reconfigured by other second signaling and cannot be overridden by other signaling.

[0079] For example, if a first beam is configured by semi-static signaling (RRC signaling), the first beam can only be reconfigured by other identical semi-static signaling (RRC signaling) and cannot be reconfigured by other signaling (other RRC signaling or DCI or MAC CE).

[0080] In some embodiments, the first signaling and the second signaling are the same signaling.

[0081] For example, the first signaling indicates first resources for the repeater, and the first signaling further indicates a first beam corresponding to at least some or all of the first resources.

[0082] Also, for example, the second signaling indicates a first beam for the repeater, and the time-frequency resource corresponding to the first beam is the first resource.

[0083] In some embodiments, the first signaling and the second signaling are different signaling.

[0084] This allows the network device to ensure the stability of forwarding using the first resource and the corresponding forwarding beam by configuring for the repeater a first resource that cannot be overwritten by other signaling (e.g., overwriting the resource or overwriting the forwarding beam corresponding to the first resource), thereby reducing unnecessary misunderstandings between the network device and the repeater and avoiding erroneous forwarding caused by misunderstandings and the resulting impact on network performance.

[0085] For example, the signal transmitted on the first resource may be a signal that is important and requires high stability, such as a common signal for the terminal device to perform initial access, a reference signal such as SSB, SIB, CORESET 0 and / or RACHoccasion, CSI-RS, etc.

[0086] The above has been a general description of the first resource or ON state, etc., and the following will describe the second resource or unavailable state.

[0087] In some embodiments, the repeater is OFF or unavailable in the second resource.

[0088] For example, the repeater does not forward signals on the second resource.

[0089] Also, for example, the repeater does not expect to receive signaling related to the second resource that dynamically instructs forwarding, and / or the repeater does not expect to receive signaling related to the second resource that configures / instructs forwarding, and / or the repeater does not expect to receive signaling related to the second resource that configures / instructs a forwarding beam, and / or the repeater does not expect to receive a forwarding signal on the second resource.

[0090] Also, for example, the network device does not transmit or receive a forwarding signal on the second resource, and / or the network device does not transmit signaling related to the second resource that dynamically instructs forwarding, and / or the network device does not transmit signaling related to the second resource that configures / instructs forwarding, and / or the network device does not transmit signaling that configures / instructs a forwarding beam on the second resource.

[0091] In some embodiments, the second resource is configured via third signaling.

[0092] In some embodiments, the third signaling indicates at least one or any combination of a start position, an offset, a period, or an end position of the second resource, although the present invention is not limited thereto and other attributes of the second resource may be indicated.

[0093] In some embodiments, the second resource may be reconfigured by other third signaling.

[0094] For example, if the second resource is configured as an unavailable resource (OFF resource) by one semi-static signaling (RRC signaling), the second resource may be reconfigured as a soft resource (flexible resource) or a hard resource (ON resource) or an unavailable resource (OFF resource) by another identical semi-static signaling (RRC signaling).

[0095] In some embodiments, the third signaling and the first signaling are the same signaling.

[0096] For example, the network device may instruct the repeater to put a first resource in the ON state and a second resource in the OFF state through one signaling (e.g., a first signaling).

[0097] In some embodiments, the third signaling, the first signaling and the second signaling are the same signaling.

[0098] For example, the network device may use one signaling (e.g., second signaling) to instruct the repeater to use a first beam, a first resource that is a time domain resource corresponding to the first beam, and a second resource in an OFF state.

[0099] As another example, the network device may instruct the repeater, by one signaling (e.g., first signaling), to generate a first beam corresponding to a first resource and a second resource, or all or at least a portion of the first resource.

[0100] In some embodiments, the second resource is a remaining resource other than the first resource and the third resource.

[0101] For example, a network device may configure a first resource (ON resource) and a third resource (flexible resource) for a repeater, and if there is no explicit instruction for a second resource, any resource other than the first resource and the third resource is the second resource.

[0102] In an embodiment of the present invention, a repeater in the OFF state does not perform forwarding (or the forwarding module of the repeater does not perform forwarding). For example, the repeater does not perform at least one of the following:

[0103] ·Receives signals from the base station via the BH link.

[0104] The amplified signal received on the BH link is transmitted on the AC link.

[0105] Receives signals via AC link.

[0106] · The amplified signal received on the AC link is transmitted on the BH link.

[0107] Thus, by configuring the second resource for the repeater in an OFF state or unavailable state, the network device can ensure that the repeater does not need to perform transmission at the time when the second resource is located, and can appropriately turn off part of the repeater's function to achieve power saving. In this way, the energy cost of the repeater can be reduced, and the energy cost of the entire network can be reduced, thereby better realizing low carbon and environmental protection.

[0108] The second resource or OFF state etc. has been briefly described above, and the third resource or flexible state will now be described.

[0109] In some embodiments, the repeater is in a flexible or soft state in the third resource.

[0110] In some embodiments, the third resource is the remaining resource other than the first resource and the second resource.

[0111] For example, a network device may configure a first resource (ON resource) and a second resource (OFF resource) for a repeater, and if there is no explicit instruction for a third resource, any resource other than the first resource and the second resource is the third resource.

[0112] In some embodiments, the third resource is configured via a fourth signaling.

[0113] For example, the network device may explicitly indicate the third resource through the fourth signaling, which indicates at least one or any combination of the start position, offset, period, and end position of the third resource. The present invention is not limited thereto, and other attributes of the third resource may also be indicated.

[0114] In some embodiments, the fourth signaling and the first signaling are the same signaling.

[0115] For example, the network device may indicate the first resource and the third resource for the repeater through one signaling (e.g., a first signaling).

[0116] In some embodiments, the fourth signaling, the first signaling and the third signaling are the same signaling.

[0117] For example, the network device may indicate the first resource, the second resource, and the third resource for the repeater through one signaling (e.g., a first signaling).

[0118] In some embodiments, the fourth signaling and the second signaling are the same signaling.

[0119] For example, the network device may indicate the first beam and the third resource for the repeater by one signaling (e.g., the second signaling).

[0120] In some embodiments, the fourth signaling and the third signaling are the same signaling.

[0121] For example, the network device may indicate the second resource and the third resource for the repeater by one signaling (e.g., the third signaling).

[0122] In some embodiments, the second beam corresponding to at least a portion of the third resources is configured / instructed via semi-static fifth signaling, and / or the third beam corresponding to at least a portion of the third resources is configured / instructed via dynamic sixth signaling.

[0123] In some embodiments, the second beam indicated by the fifth signaling can be overridden by the third beam indicated by the sixth signaling. In other words, if the time domain resources corresponding to the second beam and the time domain resources corresponding to the third beam at least partially overlap, the repeater determines to perform transmission using the third beam in the at least partially overlapping time domain resources. That is, the priority of the sixth signaling is higher than the priority of the fifth signaling, and / or the priority of the third beam is higher than the priority of the second beam, and / or the priority of the third time domain resources corresponding to the third beam is higher than the priority of the third time domain resources corresponding to the second beam.

[0124] In some embodiments, the beam corresponding to the third resource is determined based on the priority of the fifth signaling and / or the sixth signaling, for example, the fifth signaling and the sixth signaling explicitly indicate the priority of the signaling and / or the priority of the beam indicated by the signaling and / or the priority of the time domain resource indicated by the signaling.

[0125] In some embodiments, the time domain resources corresponding to the second beam indicated by the fifth signaling and / or the third beam indicated by the sixth signaling may be indicated by the seventh signaling to be OFF.

[0126] For example, a time domain resource designated as OFF is not being used for transmission, or a time domain resource designated as OFF is in an OFF state or unavailable state.

[0127] In some embodiments, the second beam indicated by the fifth signaling can be indicated as OFF, and / or the time domain resource corresponding to the third beam indicated by the sixth signaling cannot be indicated as OFF.

[0128] In some embodiments, the second beam indicated by the fifth signaling can be reconfigured by another fifth signaling.

[0129] In some embodiments, the seventh signaling and the sixth signaling are the same signaling.

[0130] In some embodiments, the sixth signaling indicates a forwarding beam by a value of a beam index. The seventh signaling indicates OFF by a beam index and / or special values ​​of other fields. For example, OFF is indicated by a special value of the beam index, which is predetermined, preconfigured, or typically predefined by the network device and repeater.

[0131] In some embodiments, whether the time domain resources corresponding to the second beam indicated by the fifth signaling and / or the third beam indicated by the sixth signaling can be indicated as OFF is determined based on priority.

[0132] In some embodiments, dynamic signaling has a higher priority than semi-static signaling.

[0133] In some embodiments, if a priority is explicitly indicated, whether a time domain resource can be indicated as OFF is determined based on the priority.

[0134] For example, if the explicitly indicated priorities are the same, the priority of the dynamic signaling is higher than the priority of the semi-static signaling, or if the explicitly indicated priorities are the same, the repeater determines whether the time domain resource can be indicated as OFF.

[0135] This allows the network device to configure a third resource in a flexible or soft state for the repeater, thereby improving the flexibility of transmission scheduling, and reducing interference and improving transmission efficiency by having the repeater not perform transmission when there is no transmission request.

[0136] In some embodiments, the repeater may support only two resources, for example, the network device may configure two of the first resource, the second resource, and the third resource for the repeater.

[0137] For example, the network device may indicate the first resource and the third resource for the repeater by one signaling (e.g., the first signaling). Also, for example, the network device may indicate the first resource for the repeater by one signaling (e.g., the first signaling) and indicate the third resource for the repeater by another signaling (e.g., the fourth signaling). The above has described the third resource or the flexible state, and the following will describe the priority of the present invention.

[0138] In some embodiments, the priority of the transfer may be at least one or a combination of the following priorities:

[0139] Priority of the beam corresponding to the transfer Configuration priority for forwarding Priority of signaling that carries the configuration corresponding to the forwarding Priority of time domain resources related to transfer - Priority of transfer signals related to transfer, etc. In some embodiments, the priority of semi-static signaling is higher than the priority of dynamic signaling, or the priority of later received signaling is higher than the priority of earlier received signaling, or the priority of dynamic signaling is higher than the priority of semi-static signaling.

[0140] In some embodiments, beam priorities may be indicated, with some beams being higher priority than others.

[0141] For example, beams for transmitting some signals have a high priority, e.g., beams for transmitting high priority signals such as SSB have a high priority.

[0142] As another example, the network side may configure some beams to have a higher priority, for example, by specifying an index for scheduling some beams, or the network side may configure or indicate the priority of one beam.

[0143] As another example, it is pre-set that beams indicated by certain signaling have a higher priority, for example, beams configured by OAM have a higher priority, and / or beams that are semi-statically instructed have a higher priority, and / or beams that are dynamically instructed have a higher priority.

[0144] In some embodiments, the priority of the transmitted signal may be indicated, and the transmitted signal itself may have a priority.

[0145] For example, signals that may have a high priority include at least one of SS, SSB, SIB, MIB, RACH, PDCCH for scheduling Msg2 and / or Msg3 and / or Msg4 and / or Msg5, PDSCH for carrying Msg2 and / or Msg4, PUSCH for carrying Msg3 and / or Msg5, CSI-RS, SRS, etc. Note that signals other than those listed above may also be used, and the present invention is not limited thereto.

[0146] Also, for example, a signal used by a terminal device served by an NCR to report a beam failure report (BFR) may have a higher priority, allowing the network side to receive the BFR from the terminal side in a timely manner and take appropriate action, thereby avoiding further major link failures, etc.

[0147] Also, for example, the priority of a signal is indicated by the network side.

[0148] In some embodiments, the information may indicate / configure the priority of the signal.

[0149] For example, beams configured by OAM have a high priority, and / or beams that are semi-statically commanded have a high priority, and / or beams that are dynamically commanded have a high priority.

[0150] Also, for example, in the above example, the important signals are mostly related to important processes and capabilities of the served terminal device, such as initial access, channel tracking, channel measurement, etc. Therefore, semi-static signaling or signaling configured by OAM may have a higher priority.

[0151] Also, for example, if a terminal device served by an NCR has traffic requiring higher reliability and delay, the network side may send dynamic signaling to indicate a new transmission beam for the NCR. In this case, the priority may be classified into three types: the beam used for transmission such as SSB has the highest priority, the dynamic override has the next highest priority, and other instructions have the lowest priority.

[0152] In some embodiments, this may be indicated as a priority of the transfer direction, i.e., the transfer direction has priority.

[0153] For example, beam collisions may occur between uplink and downlink transmissions, and the downlink transmission beam may have a higher priority, giving the network side a higher priority in communication, thereby ensuring the service of more terminal devices served by the network device.

[0154] Also, for example, in the case of a collision of beam forwarding directions, the uplink forwarding beam may have a higher priority, so that the network side can timely obtain the information requested or reported by the terminal device served by the NCR.

[0155] In some embodiments, this may be indicated as a priority for the time unit / period used or transmitted by the beam.

[0156] For example, the NCR may determine (based on received instructions or system information it has acquired) at what times more important signals need to be transmitted, and these times or periods have higher priority, and the beams associated with these times or periods have higher priority in beam collisions.

[0157] Although the above has been a brief description of priority, the present invention is not limited to this.

[0158] 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 one or more of the above-described embodiments may be used in combination.

[0159] According to an embodiment of the present invention, a repeater receives configuration information from a network device, the configuration information configuring / instructing at least a first resource, a second resource, and / or a third resource, so that the repeater can perform forwarding or not perform forwarding according to the configuration information, thereby reducing unnecessary interference and improving the transmission efficiency of the entire network.
