Description

Repeater indication method, repeater and network device Technical Field

[0001] The present application relates to the field of communication technology. Background Art

[0002] Compared with 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 bandwidth and higher data rates, and can support more types of terminals and vertical services.

[0003] To this end, in addition to traditional telecom spectrum, 5G systems are also being deployed on new spectrum with significantly higher frequencies than the traditional telecom spectrum used by 3G and 4G systems. For example, 5G systems can be deployed in millimeter wave bands (28 GHz, 38 GHz, 60 GHz, and above).

[0004] According to the propagation laws of wireless signals, the higher the carrier frequency, the more severe the signal fading during propagation. Therefore, in actual deployment, 5G systems require cell coverage enhancement methods even more than previous 3G and 4G systems, especially 5G systems deployed in the millimeter wave frequency band. How to better enhance 5G system cell coverage has become a pressing issue.

[0005] Furthermore, compared to traditional 3G and 4G systems, 5G systems utilize more advanced multi-antenna propagation technology and corresponding transmission equipment. To support more flexible and complex services, 5G systems are more complex than 3G and 4G systems. Consequently, 5G systems consume more power than 3G and 4G systems. Reducing 5G system power consumption and saving energy is a pressing issue.

[0006] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0039] The above and other features of the present application will become apparent through the following description with reference to the accompanying drawings. In the description and the accompanying drawings, specific embodiments of the present application are disclosed in detail, which illustrate some embodiments in which the principles of the present application can be adopted. It should be understood that the present application is not limited to the described embodiments. On the contrary, the present application includes all modifications, variations and equivalents that fall within the scope of the appended claims.

[0040] In the embodiments of the present application, the terms "first," "second," etc. are used to distinguish different elements in terms of title, but do not indicate the spatial arrangement or temporal order of these elements, and these elements should not be limited by these terms. The term "and / or" includes any one and all combinations of one or more of the associated listed terms. The terms "comprising," "including," "having," etc. refer to the presence of the stated features, elements, components, or components, but do not exclude the presence or addition of one or more other features, elements, components, or components.

[0041] In the embodiments of this application, the singular forms "a," "the," etc. include plural forms and should be broadly understood to mean "a" or "a type" rather than being limited to "one." Furthermore, the term "said" should be understood to include both singular and plural forms, unless the context clearly indicates otherwise. Furthermore, the term "according to" should be understood to mean "at least in part based on...", and the term "based on" should be understood to mean "at least in part based on...", unless the context clearly indicates otherwise.

[0042] In the embodiments of the present application, the term "communication network" or "wireless communication network" may refer to a network that complies with any of the following communication standards, such as Long Term Evolution (LTE), enhanced Long Term Evolution (LTE-A, LTE-Advanced), Wideband Code Division Multiple Access (WCDMA), High-Speed ​​Packet Access (HSPA), etc.

[0043] Furthermore, communication between devices in the communication system may be carried out according to communication protocols of any stage, for example, including but not limited to the following communication protocols: 1G (generation), 2G, 2.5G, 2.75G, 3G, 4G, 4.5G and future 5G, New Radio (NR), etc., and / or other currently known or future communication protocols to be developed.

[0044] In the embodiments of the present application, the term "network device" refers to, for example, a device in a communication system that connects a terminal device to the communication network and provides services to the terminal device. Network devices may include, but are not limited to, the following devices: base station (BS), access point (AP), transmission reception point (TRP), broadcast transmitter, mobile management entity (MME), gateway, server, radio network controller (RNC), base station controller (BSC), etc.

[0045] Base stations may include, but are not limited to, NodeB (NB), evolved NodeB (eNodeB or eNB), 5G base stations (gNB), IAB hosts, and the like. They may also include remote radio heads (RRHs), remote radio units (RRUs), relays, or low-power nodes (e.g., femto, pico, etc.). The term "base station" may include some or all of their functions, and each base station may provide communication coverage for a specific 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.

[0046] In the embodiments of the present application, the term "user equipment" (UE) refers to, for example, a device that accesses a communication network through a network device and receives network services, and may also be referred to as "terminal equipment" (TE). Terminal equipment may be fixed or mobile, and may also be referred to as a mobile station (MS), terminal, user, subscriber station (SS), access terminal (AT), station, etc.

[0047] Terminal devices may include, but are not limited to, the following devices: cellular phones, personal digital assistants (PDAs), wireless modems, wireless communication devices, handheld devices, machine-type communication devices, laptop computers, cordless phones, smartphones, smart watches, digital cameras, etc.

[0048] For another example, in scenarios such as the Internet of Things (IoT), the terminal device can also be a machine or device for monitoring or measurement, including but not limited to: machine type communication (MTC) terminal, vehicle-mounted communication terminal, device-to-device (D2D) terminal, machine-to-machine (M2M) terminal, and so on.

[0049] To enhance coverage, 3GPP Rel-17 introduced RF repeaters to forward transmissions between user equipment (UE) and network equipment (base stations). The RF repeaters introduced in Rel-17 are transparent to both the network and user equipment, meaning they are unaware of their presence.

[0050] Figure 1 is a schematic diagram of an application scenario of an embodiment of the present application. As shown in Figure 1, for the convenience of explanation, a network device (such as a 5G base station gNB) 101, a repeater (Repeater) 102 and a terminal device (such as UE) 103 are taken as an example for explanation, but the present application is not limited to this.

[0051] As shown in Figure 1, terminal device 103 establishes a connection with network device 101 and communicates with it. To improve communication quality, the channels / signals transmitted between terminal device 103 and network device 101 are forwarded via repeater 102. The channel / signal interaction between network device 101, terminal device 103, and repeater 102 can utilize a beam-based reception and transmission method. The beam can be a fixed beam or an adaptive beam.

[0052] As shown in FIG1 , the network device 101 may have a cell / carrier, and the network device 101, the forwarder 102, and the terminal device 103 may forward / communicate in the cell; however, the present application is not limited thereto, for example, the network device 101 may also have other cells / carriers.

[0053] In the embodiments of the present application, existing services or future services can be transmitted between the network device and the terminal device. For example, these services may include but are not limited to: enhanced mobile broadband (eMBB), massive machine type communication (mMTC), ultra-reliable low-latency communication (URLLC), and vehicle-to-everything (V2X) communication, etc.

[0054] Traditional repeaters lack the ability to communicate with network devices. Therefore, while they can help boost signal strength, they lack the flexibility to adapt to complex environmental changes. Deploying traditional repeaters in 5G networks (especially those operating at higher frequencies) can cause unnecessary interference to other network devices and / or end devices, thereby reducing overall network transmission efficiency (e.g., throughput). To enable more flexible forwarding for 5G networks, network devices must assist the repeaters and be able to configure their forwarding based on network conditions.

[0055] To enhance NR coverage, 3GPP Release 18 proposes a network-controlled repeater (NCR) solution to forward signals between network devices and terminal devices. The NCR can communicate directly with network devices via a control link to assist in NCR forwarding operations.

[0056] Figure 2 is a schematic diagram of an NCR according to an embodiment of the present application. As shown in Figure 2, NCR 202 is configured between network device 201 and terminal device 203. NCR 202 may include the following two modules / components: a mobile terminal (NCR-MT) and a forwarding module (NCR-Fwd); the NCR-Fwd may also be referred to as a routing unit (NCR-RU) of the NCR-RU. The NCR-MT is primarily used to communicate with network devices, while the NCR-Fwd is primarily used to forward signals between network devices and terminal devices.

[0057] As shown in Figure 2, the NCR of an embodiment of the present application may have three links: a control link (C-link), a backhaul link (BH link) for forwarding, and an access link (AC link). The C-link is used for communication between the NCR and network devices. The BH link is used by a forwarder to receive signals to be forwarded from a network device, or to forward signals from an AC link (e.g., from a terminal device) to a network device. The AC link is used by a forwarder to forward signals from a network device (e.g., to a terminal device), or to receive signals to be forwarded to the BH link (e.g., signals to be forwarded from a terminal device).

[0058] The inventors recognize that 5G systems are more complex than previous 3G and 4G systems. For example, they must support a wider variety of services and terminal types and must be deployed in multiple frequency bands and scenarios. Compared to traditional RF repeaters, NCRs must also have beamforming-based transceiver (transmitter) capabilities.

[0059] Figure 3 is a schematic diagram of NCR forwarding in accordance with an embodiment of the present application. As shown in Figure 3, a forwarder uses a transmit beam on an AC link to forward signals from a network device. Figure 4 is another schematic diagram of NCR forwarding in accordance with an embodiment of the present application. As shown in Figure 4, a forwarder uses a receive beam on an AC link to receive signals for forwarding to a network device.

[0060] The following describes various implementations of the present application in conjunction with the accompanying drawings. These implementations are merely exemplary and do not limit the present application. The transponder of the present application can operate in a first frequency range (FR1), a second frequency range (FR2), or both. For details about FR1 and FR2, please refer to the relevant art.

[0061] In an embodiment of the present application, a repeater can communicate with a network device. The repeater can receive a communication channel / signal sent by the network device and demodulate / decode the channel / signal, thereby obtaining information sent by the network device to the repeater. This signal processing process is hereinafter referred to as "communication". The repeater can also forward a channel / signal transmitted between a network device and a terminal device. The repeater does not demodulate / decode the channel / signal, but can perform amplification and other processing. This signal processing process is hereinafter referred to as "forwarding". "Communication" and "forwarding" are collectively referred to as "transmission". In addition, "sending or receiving on an AC link" can be equivalent to "forwarding on an AC link", and "sending or receiving on a control link" can be equivalent to "communicating on a control link". The above terms are for convenience of explanation only and do not constitute a limitation of the present application.

[0062] For convenience, the channel / signal used for direct communication between a network device and a repeater, or between a third device (e.g., a terminal device) and a repeater, can be referred to as a communication signal. When transmitting a communication signal, the repeater must encode and / or modulate it, and when receiving a communication signal, the repeater must decode and / or demodulate it. Furthermore, the channel / signal forwarded by a repeater can be referred to as a forwarded signal. The repeater may perform signal processing such as amplification on the forwarded signal, but does not decode and / or demodulate it.

[0063] In the embodiments of the present application, the repeater can also be expressed as a repeater, a RF repeater, a repeater, a RF repeater; or it can also be expressed as a repeater node, a repeater node, a repeater node; or it can also be expressed as an intelligent repeater, an intelligent repeater, an intelligent repeater, an intelligent repeater node, an intelligent repeater node, an intelligent repeater node, etc., but the present application is not limited to this.

[0064] In an embodiment of the present application, the network device can be a device of the service cell of the terminal device, a device of the cell where the repeater is located, a device of the service cell of the repeater, or a parent node of the repeater. The present application does not impose any restrictions on the name of the repeater. As long as the device can realize the above functions, it is included in the scope of the repeater of the present application.

[0065] In the embodiment of the present application, beam can also be expressed as a lobe, a reference signal (RS), a transmission configuration indication (TCI), a spatial domain filter, etc.; or, it can also be expressed 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 signals are, for example, a channel state information reference signal (CSI-RS), a sounding reference signal (SRS), an RS for use by a repeater, an RS sent by a repeater, etc. The above-mentioned TCI can also be expressed as a TCI state. The embodiments of the present application are not limited to this.

[0066] Embodiments of the first aspect

[0067] An embodiment of the present application provides an indication method for a repeater, which is described from the perspective of the repeater.

[0068] FIG5 is a schematic diagram of an indication method of a transponder according to an embodiment of the present application. As shown in FIG5 , the method includes:

[0069] 501. A forwarder receives configuration information from a network device, wherein the configuration information at least configures / indicates a first resource and / or a second resource and / or a third resource; and

[0070] 502. The forwarder forwards on the first resource and / or does not forward on the second resource according to the configuration information.

[0071] It is worth noting that FIG5 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG5 above.

[0072] In the embodiment of the present application, at least some of the first resources and / or the second resources and / or the third resources may be configured and / or indicated by the configuration information, and / or at least some of the first resources and / or the second resources and / or the third resources may be predefined or determined according to a predetermined rule. However, the present application is not limited thereto; for example, all resources may be configured and / or indicated by the configuration information, or all resources may be predefined or determined according to a predetermined rule.

[0073] In some embodiments, the network device may configure at least two of a first resource, a second resource, and a third resource for a forwarder. The first resource may be used for forwarding and may be an available resource for forwarding (e.g., a hard resource or an ON resource), the second resource may not be used for forwarding and may be an unavailable resource for forwarding (e.g., an NA resource or an OFF resource), and the third resource may be used for forwarding and may be an undetermined resource for forwarding (e.g., a flexible resource or a soft resource); the present application is not limited thereto.

[0074] For example, a network device may support a first resource, a second resource, and a third resource, and configure the forwarder with these three resources during configuration. For another example, a network device may support a first resource, a second resource, and a third resource, but configure the forwarder with at least two of these resources during configuration. For another example, a network device may support two of the first resource, the second resource, and the third resource, and configure the forwarder with either or both of these resources during configuration. The present application is not limited to the above approach.

[0075] In some embodiments, the forwarder is in an ON state or 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 forwarding. The standby state is a state that is off by default but can forward upon receiving an instruction. For example, the forwarder can be in a forwarding state or not, and in the absence of a forwarding state, the forwarder can quickly enter a forwarding state. For another example, the ON state is a state in which forwarding is performed. The forwarder forwards on the first resource.

[0076] In some embodiments, in the forwarding-capable state, when a beam is configured (for example, the operating frequency band of the repeater is in FR2), at least a portion of the first resources is configured with a beam for forwarding. For example, at least a portion of the first resources of the repeater is configured with a corresponding beam. The repeater forwards using the corresponding beam on the at least portion of the first resources.

[0077] In some embodiments, in the forwarding-capable state, in the absence of a beam configuration (e.g., when the operating frequency band of the repeater is in FR1), a default beam and / or a fixed beam is used for forwarding. For example, at least a portion of the first resource of the repeater corresponds to the default beam and / or the fixed beam. The repeater uses the default beam and / or the fixed beam for forwarding on the at least portion of the first resource.

[0078] In some embodiments, in the forwarding state, when beam configuration is available (for example, the operating frequency band of the forwarder is in FR2), all first resources of the forwarder are configured with corresponding beams. The forwarder forwards using the corresponding beams on the first resources.

[0079] In some embodiments, in the forwarding state, when no beam is configured (for example, the operating frequency band of the forwarder is in FR1), all first resources of the forwarder correspond to the default beam and / or the fixed beam. The forwarder forwards using the default beam and / or the fixed beam in the first resource.

[0080] In the above description, "capable of forwarding" can mean that the forwarder has the ability to forward and / or that the forwarder can forward on the first resource, but the first resource is not necessarily actually used for forwarding. "Forwarding" can mean that the forwarder is instructed to forward, that the forwarder will forward, that the forwarder can forward on the 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 does not constitute a limitation of this application.

[0081] Furthermore, in the context of this application, "on state," "off state," "available state," "unavailable state," "hard state," "soft state," "flexible state," and the like may refer to forwarders, meaning forwarders may have these states, or to resources, meaning resources may have these states. Those skilled in the art will understand the specific meanings of these terms in this application.

[0082] In some embodiments, a time unit of the first resource corresponds to a forwarding beam. For example, each time unit has a corresponding forwarding beam. For another example, at least some time units have corresponding beams. The above-mentioned time unit can be one or any combination of a time slot, a symbol, a subframe, or a mini-slot, and the present application is not limited thereto.

[0083] For example, the forwarding beam is configured or indicated by the network device, or is determined according to a standard predefined rule, or is preset (for example, before leaving the factory).

[0084] In some embodiments, the forwarder uses the forwarding beam when the first resource is in an on state. For example, the forwarding beam is a beam on a backhaul (BH) link and / or a beam on an access (AC) link.

[0085] For example, the repeater receives a communication signal from the network device using a beam on the backhaul (BH) link, and / or the repeater sends a communication signal to the network device using a beam on the backhaul (BH) link.

[0086] For example, the repeater receives a forwarding signal from the network device using the beam on the access (AC) link, and / or the repeater sends a forwarding signal to the network device using the beam on the access (AC) link.

[0087] In some embodiments, the forwarding beam corresponding to at least part or all of the first resources is configured by semi-static signaling, such as radio resource control (RRC) signaling, MAC CE, etc.

[0088] In some embodiments, the first resource and / or the forwarding beam may be configured by semi-static signaling. The first resource and the forwarding beam may be configured by the same signaling, or the first resource and the forwarding beam may be configured by different signaling.

[0089] In some embodiments, the first resource has the highest priority.

[0090] In some embodiments, the beam indication of the first resource can only be reconfigured but cannot be overwritten.

[0091] For example, if a first resource is configured as a hard resource (ON resource) by a semi-static signaling, the first resource can be reconfigured as a soft resource (flexible resource) or an unavailable resource (OFF resource) by another same semi-static signaling, or be canceled / erased / removed.

[0092] For another example, if the forwarding beam corresponding to the first resource is configured and / or indicated by semi-static signaling, the forwarding beam can be reconfigured to the same forwarding beam by another identical semi-static signaling, or the forwarding beam can be reconfigured to a different forwarding beam by another identical semi-static signaling, or the forwarding beam can be canceled / erased / removed by another identical semi-static signaling. Optionally, the forwarding beam cannot be overwritten by other signaling (e.g., a DCI signaling or another semi-static signaling). That is, the forwarder does not expect to receive another signaling indicating and / or configuring another forwarding beam for the first resource, and / or the network device will not send another signaling indicating and / or configuring another forwarding beam for the first resource to the forwarder.

[0093] In some embodiments, the network device indicates the first resource through first signaling and configures a first beam for the first resource through second signaling.

[0094] For example, the first signaling indicates at least one or any combination of the following of the first resource: a starting position, an offset, a period, and an ending position; the present application is not limited thereto, and other attributes of the first resource may also be indicated.

[0095] In some embodiments, the second signaling indicates the first beam, and / or the second signaling indicates the time domain resources corresponding to the first beam.

[0096] For example, the second signaling may directly indicate the first beam, or may directly indicate the time domain resources corresponding to the first beam, or may simultaneously indicate the first beam and its corresponding time domain resources.

[0097] In some embodiments, the first resource and the time domain resource corresponding to the first beam partially overlap, or the first resource and the time domain resource corresponding to the first beam completely overlap (coincide), or the first resource at least includes the time domain resource corresponding to the first beam.

[0098] In some embodiments, the first resource can be reconfigured by another first signaling.

[0099] For example, if a first resource is configured as a hard resource (ON resource) by a semi-static signaling (RRC signaling), the first resource can also be reconfigured as a soft resource (flexible resource) or an unavailable resource (OFF resource) or a hard resource (ON resource) by another identical semi-static signaling (RRC signaling).

[0100] In some embodiments, the first beam can only be reconfigured by another second signaling and cannot be overwritten by other signaling.

[0101] For example, if the first beam is configured by a semi-static signaling (RRC signaling), the first beam can only be reconfigured by another identical semi-static signaling (RRC signaling) but cannot be reset by other signaling (other RRC signaling or DCI or MAC CE).

[0102] In some embodiments, the first signaling and the second signaling are the same signaling.

[0103] For example, the first signaling indicates a first resource for the repeater, and the first signaling also indicates a first beam corresponding to at least part or all of the first resource.

[0104] For another example, the second signaling indicates the first beam to the repeater, and the time-frequency resource corresponding to the first beam is the first resource.

[0105] In some embodiments, the first signaling and the second signaling are different signaling.

[0106] Therefore, the network device configures the forwarder with a first resource that cannot be rewritten by other signaling (for example, rewriting the resource or rewriting the forwarding beam corresponding to the first resource), which can ensure the stability of forwarding using the first resource and the corresponding forwarding beam, thereby reducing unnecessary misunderstandings between the network device and the forwarder, and avoiding erroneous forwarding caused by misunderstandings and the resulting impact on network performance.

[0107] For example, the signal forwarded on the first resource may be an important signal with high stability requirements, such as a common signal used for initial access of a terminal device, reference signals such as SSB, SIB, CORESET 0 and / or RACHoccasion, CSI-RS, etc.

[0108] The first resource or the ON state is schematically described above, and the second resource or the unavailable state is described below.

[0109] In some embodiments, the forwarder is in an OFF state or an unavailable state when the second resource is in an OFF state.

[0110] For example, the repeater does not forward the signal in the second resource.

[0111] For another example, the forwarder does not expect to receive signaling indicating dynamic forwarding related to the second resource, and / or the forwarder does not expect to receive signaling indicating configuration / forwarding related to the second resource, and / or the forwarder does not expect to receive signaling indicating configuration / forwarding beam in the second resource, and / or the forwarder does not expect to receive forwarding signal in the second resource.

[0112] For another example, the network device does not send or receive forwarding signals on the second resource, and / or the network device does not send signaling related to the second resource that dynamically indicates forwarding, and / or the network device does not send signaling related to the second resource that configures / indicates forwarding, and / or the network device does not send signaling related to the second resource that configures / indicates forwarding beams.

[0113] In some embodiments, the second resource is configured via third signaling.

[0114] For example, the third signaling indicates at least one or any combination of the following of the second resource: a starting position, an offset, a period, and an ending position; the present application is not limited thereto, and for example, other attributes of the second resource may also be indicated.

[0115] In some embodiments, the second resource can be reconfigured by another third signaling.

[0116] For example, if the second resource is configured as an unavailable resource (OFF resource) by one semi-static signaling (RRC signaling), the second resource can 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).

[0117] In some embodiments, the third signaling and the first signaling are the same signaling.

[0118] For example, the network device may indicate the first resource in the ON state and the second resource in the OFF state to the repeater through a signaling (eg, a first signaling).

[0119] In some embodiments, the third signaling, the first signaling and the second signaling are the same signaling.

[0120] For example, the network device may indicate to the repeater through a signaling (eg, a second signaling) a first beam, a time domain resource corresponding to the first beam, namely a first resource, and a second resource in an OFF state.

[0121] For another example, the network device may indicate to the forwarder, through a signaling (eg, a first signaling), the first resource and the second resource, or the first beam corresponding to all or at least part of the first resource.

[0122] In some embodiments, the second resource is the remaining resource except the first resource and the third resource.

[0123] For example, the network device may configure a first resource (ON resource) and a third resource (flexible resource) for the forwarder. In the absence of an explicit indication of the second resource, other resources except the first resource and the third resource are the second resources.

[0124] In the embodiment of the present application, a forwarder in the OFF state does not forward (or a forwarding module of the forwarder does not forward). For example, the forwarder does not forward means that it does not do at least one of the following:

[0125] --Receive signals from the base station on the BH link;

[0126] --Send the amplified signal received on the BH link on the AC link;

[0127] --Receive signals on the AC link;

[0128] --Send the amplified signal received on the AC link on the BH link.

[0129] By configuring a second resource in an OFF or unavailable state for the forwarder, the network device can ensure that the forwarder does not need to forward messages when the second resource is available, thereby appropriately disabling some of the forwarder's functions to save power. This reduces energy consumption for both the forwarder and the entire network, further contributing to low-carbon environmental protection.

[0130] The second resource or the OFF state is schematically described above, and the third resource or the flexible state is described below.

[0131] In some embodiments, the forwarder is in a flexible state or a soft state on the third resource.

[0132] In some embodiments, the third resource is the remaining resource except the first resource and the second resource.

[0133] For example, the network device may configure a first resource (ON resource) and a second resource (OFF resource) for the forwarder. In the absence of an explicit indication of a third resource, other resources except the first resource and the second resource are the third resource.

[0134] In some embodiments, the third resource is configured via fourth signaling.

[0135] For example, the network device may explicitly indicate the third resource through a fourth signaling. The fourth signaling indicates at least one or any combination of the following attributes of the third resource: a starting position, an offset, a period, and an ending position; the present application is not limited thereto, and other attributes of the third resource may also be indicated.

[0136] In some embodiments, the fourth signaling and the first signaling are the same signaling.

[0137] For example, the network device may indicate the first resource and the third resource to the forwarder through a signaling (eg, a first signaling).

[0138] In some embodiments, the fourth signaling, the first signaling and the third signaling are the same signaling.

[0139] For example, the network device may indicate the first resource, the second resource, and the third resource to the forwarder through a signaling (eg, a first signaling).

[0140] In some embodiments, the fourth signaling and the second signaling are the same signaling.

[0141] For example, the network device may indicate the first beam and the third resource to the repeater through a signaling (eg, the second signaling).

[0142] In some embodiments, the fourth signaling and the third signaling are the same signaling.

[0143] For example, the network device may indicate the second resource and the third resource to the forwarder through one signaling (eg, the third signaling).

[0144] In some embodiments, the second beam corresponding to at least part of the third resources is configured / indicated through semi-static fifth signaling, and / or the third beam corresponding to at least part of the third resources is configured / indicated through dynamic sixth signaling.

[0145] In some embodiments, the second beam indicated by the fifth signaling can be overwritten by the third beam indicated by the sixth signaling. That is, when the time domain resources corresponding to the second beam and the time domain resources corresponding to the third beam at least partially overlap, the forwarder determines to use the third beam for forwarding in the at least partially overlapping time domain resources. In other words, the sixth signaling has a higher priority than the fifth signaling, and / or the third beam has a higher priority than the second beam, and / or the third time domain resources corresponding to the third beam have a higher priority than the third time domain resources corresponding to the second beam.

[0146] 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 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 are explicitly indicated in the fifth signaling and the sixth signaling.

[0147] 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 can be indicated as OFF by the seventh signaling.

[0148] For example, the time domain resource indicated as OFF is not used for forwarding, or the time domain resource indicated as OFF is in an OFF state or an unavailable state.

[0149] In some embodiments, the second beam indicated by the fifth signaling can be indicated as OFF, and / or the time domain resources corresponding to the third beam indicated by the sixth signaling cannot be indicated as OFF.

[0150] In some embodiments, the second beam indicated by the fifth signaling can be reconfigured by another fifth signaling.

[0151] In some embodiments, the seventh signaling and the sixth signaling are the same signaling.

[0152] In some embodiments, the sixth signaling indicates the forwarding beam through the value of the beam index. The seventh signaling indicates OFF through a special value of a beam index and / or other field. For example, OFF is indicated by a special value of the beam index, where the special value is pre-agreed, pre-configured, or pre-defined by a standard between the network device and the forwarder.

[0153] 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 according to priority.

[0154] For example, the priority of dynamic signaling is higher than the priority of semi-static signaling.

[0155] In some embodiments, when the priority is explicitly indicated, whether the time domain resource can be indicated as OFF is determined according to the priority.

[0156] For example, when the priorities of explicit indications are the same, the priority of dynamic signaling is higher than the priority of semi-static signaling. For another example, when the priorities of explicit indications are the same, the repeater determines whether the time domain resource can be indicated as OFF.

[0157] Therefore, the network device configures the third resource in a flexible state or a soft state for the forwarder, which can increase the flexibility of forwarding scheduling and prevent the forwarder from forwarding when there is no forwarding demand to reduce interference and improve forwarding efficiency.

[0158] In some embodiments, the forwarder may only support two resources. For example, the network device may configure two of the first resource, the second resource, and the third resource for the forwarder.

[0159] For example, the network device may indicate the first resource and the third resource to the forwarder through a single signaling (e.g., the first signaling). For another example, the network device may indicate the first resource to the forwarder through a single signaling (e.g., the first signaling) and indicate the third resource to the forwarder through another signaling (e.g., the fourth signaling). The third resource or flexible state is described above, and the priority of this application is described below.

[0160] In some embodiments, the forwarding priority can be at least one or a combination of the following priorities:

[0161] --The priority of the forwarding beam corresponding to this forwarding;

[0162] --The priority of the configuration corresponding to this forwarding;

[0163] --The priority of the signaling that carries the configuration corresponding to this forwarding;

[0164] --The priority of the time domain resources associated with this forwarding;

[0165] --The priority of the forwarding signal, etc.

[0166] In some embodiments, the priority of semi-static signaling is higher than that of dynamic signaling, or the priority of signaling received later is higher than that of signaling received earlier, or the priority of dynamic signaling is higher than that of semi-static signaling.

[0167] In some embodiments, it can be expressed as a priority of beams: the priority of one part of the beams is higher than the priority of another part.

[0168] For example, beams used to forward certain signals have a higher priority, such as beams used to forward high-priority signals such as SSB.

[0169] For another example, the network side configures a part of beams with a high priority, such as specifying a part of beam scheduling index; or, the network side configures or indicates the priority of a beam.

[0170] For another example, it is agreed in advance that the beams indicated by certain signaling have a high priority, for example, the beams configured by OAM have a high priority, and / or the beams indicated by semi-static indications have a high priority, and / or the beams indicated by dynamic indications have a high priority.

[0171] In some embodiments, it may be manifested as the priority of the forwarded signal: the forwarded signal itself has a priority.

[0172] For example, signals with higher priorities may include at least one of the following: 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. Of course, signals other than the above signals may also be used, and this application is not limited thereto.

[0173] For example, the signal used by the terminal device served by NCR to report BFR (beam failure report) may also have a higher priority, so that the network side can receive the BFR from the terminal side in time and perform appropriate processing to avoid further and larger link failures.

[0174] For another example, the signal priority is indicated by the network side.

[0175] In some embodiments, it can be expressed as indication / configuration information or signaling priority.

[0176] For example, the beam configured by OAM has a high priority, and / or the beam indicated semi-statically has a high priority, and / or the beam indicated dynamically has a high priority.

[0177] For example, the important signals in the above examples are mostly related to key processes and capabilities such as initial access, channel tracking, and channel measurement of the served terminal devices. Therefore, semi-static signaling or signaling configured by OAM may have a higher priority.

[0178] For example, when a terminal device served by an NCR has services that require high reliability and latency, the network may send dynamic signaling to indicate a new transmission beam to the NCR. In this case, priorities may be divided into three categories: for example, beams used for forwarding SSBs have the highest priority, dynamic rewriting has the second highest priority, and other indications have a lower priority.

[0179] In some embodiments, it can be expressed as a priority of the forwarding direction: the forwarding direction has a priority.

[0180] For example, beam conflicts may occur between uplink forwarding and downlink forwarding. The downlink forwarding beam can be given higher priority and have a higher priority on the network side in communications, which can guarantee the services of more terminal devices served by the network device.

[0181] For another example, in the case of a beam forwarding direction conflict, the uplink forwarding beam may be given priority so that the network side can promptly obtain the request or reported information of the terminal device served by the NCR.

[0182] In some embodiments, it can be expressed as the priority of the time unit / time period for the beam to be used or forwarded.

[0183] For example, NCR can determine (based on received instructions or system information obtained by itself) at what times more important signals may need to be forwarded. These times or time periods have higher priorities, and the beams associated with these times or time periods have higher priorities in beam conflicts.

[0184] The above is only an illustrative description of the priority, but the present application is not limited thereto.

[0185] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0186] According to an embodiment of the present application, a forwarder receives configuration information from a network device, wherein the configuration information at least configures / indicates a first resource, a second resource, and / or a third resource. Thus, the forwarder can forward or not forward based on the configuration information, thereby reducing unnecessary interference and improving the transmission efficiency of the entire network.
