Description

Information 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] 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.

[0006] Summary of the Invention

[0007] To better address coverage issues in actual cellular mobile communication system deployments, RF relays (RF repeaters) are commonly used to amplify and forward communication signals between terminal devices and network equipment. RF repeaters are widely used in the deployment of 3G and 4G systems. Generally speaking, an RF repeater is a device that amplifies and forwards signals between devices in the RF domain. In other words, an RF repeater is a non-regenerative relay node that simply amplifies and forwards all received signals.

[0008] The inventors have found that using traditional radio frequency repeaters to enhance coverage is one of the feasible solutions to the coverage problems encountered in the deployment of 5G systems. However, since the forwarding behavior of traditional radio frequency repeaters is not controlled by the network, on the one hand, the effect of amplifying and forwarding the target signal may not be ideal, and on the other hand, it may cause significant interference to other devices in the network, increase the noise and interference level of the system, and thus reduce network throughput. Specifically, taking the antenna direction as an example, compared with 3G and 4G systems, the 5G system adopts a more advanced and complex MIMO (multiple input and multiple output) technology. In the 5G system, especially for higher carrier frequencies, directional antennas become basic components of network devices and terminal devices, and sending and receiving signals based on beamforming technology is the basic signal transmission method in the 5G system. The (analog) beam direction and width of network devices and terminal devices may change dynamically due to factors such as position changes (that is, beam switching). However, the antenna of the traditional radio frequency repeater cannot dynamically adjust the direction and the beam is wide. The beam direction and beam width of its transceiver antenna cannot flexibly match the position of the network device and terminal device and the dynamic changes of the beam direction and width of the transceiver antenna. When such a RF repeater is configured in a 5G system, on the one hand, the performance / effect of amplifying / enhancing the target signal may not be significant due to the mismatch between the beam direction and beam width of its transceiver antenna and the dynamic changes in the beam direction and width of the transceiver antennas of the network equipment and terminal equipment. On the other hand, due to the use of a wider transmission beam, it may also cause significant interference to other devices within a larger range (such as network equipment or terminal equipment), thereby increasing the noise and interference level of the entire system and thus reducing network throughput.

[0009] In response to at least one of the above problems, an embodiment of the present application provides an information indication method, a forwarder, and a network device.

[0010] According to one aspect of an embodiment of the present application, there is provided an information indication method, applied to a forwarder, the method comprising:

[0011] The mobile terminal of the repeater receives indication information for controlling a forwarding unit of the repeater, where the indication information includes first information for indicating time domain resources, where the time domain resources are related to a subcarrier spacing.

[0012] According to another aspect of an embodiment of the present application, a repeater is provided, including:

[0013] A receiving unit receives indication information for controlling a forwarding unit of the forwarder, wherein the indication information includes first information for indicating a time domain resource, and the time domain resource is related to a subcarrier spacing.

[0014] According to another aspect of an embodiment of the present application, there is provided an information indication method, applied to a network device, the method comprising:

[0015] The network device sends indication information for controlling a forwarding unit of the forwarder to a mobile terminal of the forwarder, where the indication information includes first information for indicating a time domain resource, where the time domain resource is related to a subcarrier spacing.

[0016] According to another aspect of an embodiment of the present application, a network device is provided, including:

[0017] A sending unit is configured to send indication information for controlling a forwarding unit of the forwarder to a mobile terminal of the forwarder, wherein the indication information includes first information for indicating a time domain resource, where the time domain resource is related to a subcarrier spacing.

[0018] According to another aspect of an embodiment of the present application, a communication system is provided, comprising: the repeater of the aforementioned aspect and / or the network device of the aforementioned aspect.

[0019] One of the beneficial effects of the embodiments of the present application is that: the network device can control the repeater so that the beam (corresponding time domain resources) when the repeater is forwarding can match the beam (corresponding time domain resources) of the received forwarded signal, or the time domain resources corresponding to the forwarding unit on state can match the time domain resources of the data transmission between the network device and the terminal device, thereby improving the effect of amplifying / enhancing the signal, saving the power consumption of the repeater, reducing interference to other devices in the network, and improving network throughput.

[0040] In the embodiments of the present application, the terms "first", "second", etc. are used to distinguish different elements from the name, 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 all utilizes a beam-based reception and transmission method.

[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 terminal devices, thereby reducing the transmission efficiency (e.g., throughput) of the entire network. To make repeater forwarding more flexible and adaptable to the characteristics of 5G networks, network devices need to assist the repeaters and be able to configure their forwarding according to 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] FIG2 is a schematic diagram of an NCR according to an embodiment of the present application. As shown in FIG2 , 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) of the transponder and a forwarding unit (NCR-Fwd) of the transponder; the NCR-Fwd may also be referred to as a routing unit (NCR-RU) of the 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. The NCR-MT and NCR-Fwd are functional entities, and their functions may be implemented by the same or different hardware modules.

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

[0059] Furthermore, traditional repeaters are typically manually switched on and off, and cannot dynamically adapt to data transmission between network devices and UEs. Generally, data transmission between network devices and UEs is not always ongoing. If the repeater remains on even when no network devices or UEs are transmitting data, it will not only increase unnecessary power consumption but also potentially interfere with other devices, reducing network throughput. Therefore, compared to traditional RF repeaters, NCRs require the ability to control the forwarding function on and off.

[0060] However, the inventors found that how the repeater indicates / determines the time period (time domain resources) corresponding to the AC link beam and / or the time period (time domain resources) corresponding to the forwarding unit being turned on / off, especially how to indicate / determine the subcarrier spacing used to determine the time domain resources corresponding to the AC link beam and / or the subcarrier spacing used to determine the time domain resources corresponding to the forwarding unit being turned on / off has become an urgent problem to be solved.

[0061] The following describes various implementations of the present application in conjunction with the accompanying drawings. These implementations are merely illustrative and are not intended to limit the present application.

[0062] 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 to obtain information sent by the network device to the repeater. The signal processing process is hereinafter referred to as "communication". The repeater can also forward the channel / signal transmitted between the network device and the terminal device. The repeater does not demodulate / decode the channel / signal, but can perform amplification and other processing. The signal processing process is hereinafter referred to as "forwarding". "Communication" and "forwarding" are collectively referred to as "transmission". In addition, "sending or receiving on the AC link (using a beam)" can be equivalent to "forwarding on the AC link (using a beam)", and "sending or receiving on the control link" can be equivalent to "communicating on the control link". The above terms are for convenience of explanation only and do not constitute a limitation of the present application. In some cases, "forwarding unit" can be interchangeable with "forwarding behavior".

[0063] 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.

[0064] In the embodiments of the present application, the repeater can also be expressed as a network-controlled repeater, a repeater, a radio frequency repeater, a repeater, a radio frequency 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.

[0065] 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.

[0066] 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.

[0067] The following describes the method in conjunction with embodiments.

[0068] Embodiments of the first aspect

[0069] An embodiment of the present application provides an information indication method, which is described from the perspective of a forwarder.

[0070] FIG3 is a schematic diagram of an information indication method according to an embodiment of the present application. As shown in FIG3 , the method includes:

[0071] 301. The mobile terminal of the repeater receives indication information for controlling a forwarding unit of the repeater, where the indication information includes first information for indicating time domain resources, where the time domain resources are related to a subcarrier spacing.

[0072] It is worth noting that FIG3 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 FIG3 above.

[0073] In some embodiments, the indication information may be first indication information for controlling the access link beam of the repeater, or second indication information for controlling the forwarding unit of the repeater to be turned on and / or off, or third indication information for controlling the return link beam of the repeater, as described in detail below.

[0074] (1) First instruction information

[0075] In some embodiments, an AC link beam, also referred to as a terminal device-side beam, refers to the receive beam / transmit beam employed by a repeater on the AC link. The transmit beam forwards signals from a network device to the terminal device, while the receive beam forwards signals from the terminal device to the network device. The antenna beam, for example, refers to the main lobe of the antenna array's radiation pattern.

[0076] In some embodiments, the repeater can support multiple beams (or antenna beams) of different directions and / or widths, and there may be an association relationship between the beams. For example, the association relationship between the first beam and the second beam includes: the beam center direction of the first beam and the second beam is the same, and / or the beam peak direction of the first beam and the second beam is the same, and / or the first beam and the second beam are quasi-co-located (for example, QCL type D), and / or the first beam is within the range of the second beam, or the second beam is within the range of the first beam, and / or the beam width of the first beam is within the beam width range of the second beam, and / or the beam width of the second beam is within the beam width range of the first beam. Among them, the beam center direction refers to, for example, the geometric center of the half power contour of the beam, and the beam peak direction refers to, for example, the direction of the maximum EIRP of the beam.

[0077] Figure 4 is a schematic diagram of the AC link beam of the NCR in an embodiment of the present application. As shown in Figure 4, the repeater can support multiple beams beam#1, beam#2, beam#3, beam#4, and beam#5 with different directions and / or widths. For example, beam#1 and beam#5 are associated with each other.

[0078] In some embodiments, the repeater explicitly and / or implicitly reports to the terminal device the number of beams supported by its AC link and / or the association between beams.

[0079] For example, the forwarder directly reports the number of beams supported by the AC link, such as one of 1 / 2 / 4 / 8.

[0080] For another example, a transponder reports the number of beams and the association between the beams. For example, the first beam number is one of 1 / 2 / 4 / 8, and the second beam number is one of 1 / 2 / 4 / 8 (the value range is the same as or different from that of the first beam). If there are M second beams, each first beam is associated with M second beams.

[0081] For another example, the repeater reports the number of beams and the association between the beams, for example, the first beam is one of 1 / 2 / 4 / 8, and the second beam is one of 1 / 2 / 4 / 8 / 16 / 32 / 64. If there are N first beams and M second beams, each first beam is associated with M / N second beams.

[0082] For another example, the repeater reports the number of beams and the association between the beams. For example, the first beam is one of 1 / 2 / 4 / 8. The number of second beams associated with different first beams can be different. For example, different first beams correspond to 1 / 2 / 4 / 8 second beams respectively.

[0083] For another example, the repeater reports the number of beams and the association between beams. It reports the total number of beams and the number N of first beams, and then indirectly reports the number M of second beams and the second beam associated with each first beam.

[0084] The association relationship between the second beam and the first beam is as described above, and the first beam is, for example, called the source beam of the second beam, or the QCL source beam.

[0085] In some embodiments, in order to control the access link beam of the repeater, the network device sends first indication information to the repeater for controlling the access link beam of the repeater, and the first indication information includes access link beam indication information, and / or identification information, and / or grouping information, and / or priority information, and / or first information for indicating the first time domain resource corresponding to the access link beam.

[0086] In some embodiments, the first indication information is carried by at least one of a first RRC signaling, a first MAC signaling, or a first PHY signaling. The first PHY signaling may be a first DCI, such as a unicast DCI or a group common DCI. On the other hand, the format of the first DCI may be a traditional DCI format (e.g., 1_1, 2_0) or a newly introduced DCI format.

[0087] In some embodiments, the first indication information may indicate which beam the forwarder should use (for forwarding) during a certain time period. That is, the first indication information includes at least access link beam indication information indicating an AC link beam. The access link beam indication information may be a beam index. The indicated beam is one of the first beams, and the range of indications does not include the second beam. However, this embodiment of the present application is not limited thereto, and the indicated beam may also include the second beam.

[0088] In some embodiments, the first indication information may further include first information for indicating the time domain resource (first time domain resource) corresponding to the indicated beam, wherein the time domain resource (first time domain resource) corresponding to the beam refers to the time period for forwarding using the beam.

[0089] In some embodiments, the beam indicated in the first indication information is periodic or semi-persistent (the first two can also be called semi-static) or non-periodic (or dynamic), or, accordingly, the time domain resource (first time domain resource) corresponding to the beam indicated in the first indication information is periodic or semi-persistent or non-periodic.

[0090] I. The first time domain resource is periodic or semi-persistent

[0091] In some embodiments, the first indication information is carried by the first RRC signaling, the first RRC signaling includes one or more first configuration information, and the first configuration information includes all information of the first indication information.

[0092] In some embodiments, the first indication information is carried by the first MAC signaling, the first MAC signaling includes one or more first configuration information, and the first configuration information includes all information of the first indication information.

[0093] In some embodiments, the first indication information is carried by the first RRC signaling + first MAC signaling and / or first PHY signaling, the first RRC signaling includes one or more first configuration information, the first configuration information includes all or part of the first indication information, the first MAC signaling and / or the first PHY signaling also includes identification information for indicating one or more first configurations among the multiple first configuration information and / or part of the first indication information.

[0094] In some embodiments, the first indication information is carried by the first MAC signaling + first PHY signaling, the first MAC signaling includes one or more first configuration information, the first configuration information includes all or part of the first indication information, and the first PHY signaling also includes identification information for indicating one or more first configurations among the multiple first configuration information and / or part of the first indication information.

[0095] The first information includes information indicating a first time domain resource within a period and / or period information. The first configuration information includes all or part of the first information indicating the first time domain resource, and the first MAC signaling and / or the first PHY signaling includes part of the first information.

[0096] Part of the first information included in the first configuration information includes period information, and part of the first information included in the first MAC signaling and / or the first PHY signaling includes information used to indicate first time domain resources within a period.

[0097] The information indicating the first time domain resource within a period includes at least one first duration information and / or at least one first offset information; the first duration includes a millisecond-level duration and / or a slot-level duration and / or a symbol-level duration; and the first offset includes a millisecond-level offset and / or a slot-level offset and / or a symbol-level offset.

[0098] The following example illustrates this.

[0099] In some embodiments, the first indication information may be carried only by the first RRC signaling.

[0100] The first RRC signaling may include one or more first configuration information, and the first configuration information includes all information of the first indication information. That is, the forwarder can receive one or more first indication information carried by the first RRC signaling. The first information included in the first indication information may include information and / or period information for indicating the first time domain resource within a period. The information for indicating the first time domain resource within a period includes at least one first duration information and / or at least one first offset information of the first time domain resource. For example, the first information may include period information, one or more first offset information, and one or more first duration information. The beam indicated by the access link beam indication information includes one or more beams, one beam corresponds to one or more first offset information and / or one or more first duration information, different beams correspond to the same or different first offset information, and / or different beams correspond to the same or different first duration information. The aforementioned first offset refers to the offset between the starting position of the time domain resource of the corresponding beam within a period and a reference position. The reference position may be the starting position of the system frame after receiving the first RRC signaling, or the ending position of the time domain resource corresponding to other beams, etc., but the embodiments of the present application are not limited to this.

[0101] In some embodiments, the aforementioned period and / or first duration and / or first offset includes at least one time unit, and the first information indicates the aforementioned period and / or first duration and / or first offset by indicating the number of the time units. The at least one time unit is continuous in the time domain, or the at least one time unit is discontinuous in the time domain. The time unit is, for example, a subframe, a time slot, a symbol, a mini-slot, a millisecond, etc. That is, the period includes a millisecond-level period and / or a time slot-level period and / or a symbol-level period, the first duration includes a millisecond-level duration and / or a time slot-level duration and / or a symbol-level duration, the first offset includes a millisecond-level offset and / or a time slot-level offset and / or a symbol-level offset, and the first time domain resource (the length of the time unit) is related to the subcarrier spacing. How to determine the first time domain resource based on the subcarrier spacing will be described later.

[0102] FIG5A to FIG5G are schematic diagrams of the first indication information of the present application. As shown in FIG5A , the indicated beam is Beam#1, corresponding to a first offset and a first duration. As shown in FIG5B , the indicated beams are Beam#1 and Beam#2, corresponding to a first offset and a first duration. The specific first duration of each beam can be determined according to the implementation. As shown in FIG5C , the indicated beams are Beam#1 and Beam#2, corresponding to a first offset and two first durations. The two first durations correspond to Beam#1 and Beam#2, respectively. 2; As shown in FIG5D , the indicated beams are Beam#1 and Beam#2, corresponding to two first offsets and one first duration, the two first offsets correspond to Beam#1 and Beam#2 respectively, the reference positions of the first offsets are the same, and the first durations of the two beams are the same; As shown in FIG5E , the indicated beams are Beam#1 and Beam#2, corresponding to two first offsets and two first durations, the two first offsets correspond to Beam#1 and Beam#2 respectively, and the two first durations correspond to Beam#1 and Beam#2 respectively; As shown in FIG5F As shown, the indicated beams are Beam#1 and Beam#2, corresponding to two first offsets and one first duration, the two first offsets correspond to Beam#1 and Beam#2 respectively, and Beam#1 and Beam#2 correspond to the same first duration; as shown in FIG5G , the indicated beams are Beam#1 and Beam#2, corresponding to two first offsets and two first durations, the two first offsets correspond to Beam#1 and Beam#2 respectively, and the two first durations correspond to Beam#1 and Beam#2 respectively. The difference from FIG5E is that the reference position of the first offset 2 is different.

[0103] The beams in Figures 5A to 5G above take Beam#1 and Beam#2 as examples, but this application is not limited to this and can also indicate other numbers of beams. In addition, the time domain resources corresponding to the same beam in one period are continuous, but not limited to this, and can also be discontinuous (for example, one beam corresponds to multiple first offsets and / or first duration information, and thus discontinuous time domain resources can be configured).

[0104] The one or more first indication information are included in an information element / field (IE / field) of the first RRC signaling. The IE / field may be forwarder-specific, i.e., the IE / field is applicable only to the forwarder and is used to control the forwarding unit of the forwarder. The IE / field may also include the second indication information and / or the third indication information, or the first indication information may include the second indication information and / or the third indication information, or the first indication information may serve as the second indication information, as will be described in detail in the examples below.

[0105] In some embodiments, the first indication information is carried by a first RRC signaling, and a first MAC signaling and / or a first PHY signaling, the implementation of the first RRC signaling being as described above, and the first MAC signaling and / or the first PHY signaling being used to activate and / or deactivate one or more first configurations among the multiple first configuration information. For example, the first MAC signaling and / or the first PHY signaling further includes identification information for indicating one or more first configurations among the multiple first configuration information.

[0106] For example, the first RRC signaling includes multiple first configuration information, and the identification information in the first MAC signaling and / or the first PHY signaling is the first configuration corresponding to one or more activated first indication information. The forwarder adopts the corresponding beam to forward in the corresponding time domain resources according to the activated first configuration. For example, the first RRC signaling includes 8 first configuration information, and the first MAC signaling is 00000010, then the seventh first configuration information is activated, and examples are not given here one by one. Figure 6 is a schematic diagram of the first indication information of an embodiment of the present application. As shown in Figure 6, the first indication information is carried by the first RRC signaling and the first MAC signaling. The seventh first configuration information is activated. The beams indicated in the seventh first configuration information are Beam#1 and Beam#2. The first information includes two first offsets and two first durations, corresponding to Beam#1 and Beam#2, respectively.

[0107] In some embodiments, when the first PHY signaling is used for activation, it may be directly activated based on the first RRC signaling configuration, or activated based on further configuration of the first MAC signaling (ie, activated and / or deactivated through MAC CE and DCI).

[0108] In some embodiments, the first indication information is carried by a first MAC signaling and a first PHY signaling, the first MAC signaling includes one or more first configuration information, the specific implementation of the first configuration information is similar to that of the first RRC signaling, and the first PHY signaling is used to activate and / or deactivate one or more first configurations in the multiple first configuration information. For example, the first PHY signaling also includes identification information for indicating one or more first configurations in the multiple first configuration information. The forwarder uses the corresponding beam to forward in the corresponding time domain resources according to the activated configuration.

[0109] In some embodiments, the first indication information is carried by a first RRC signaling, a first MAC signaling and / or a first PHY signaling. The difference from the aforementioned embodiment is that each information of the first information (period and / or at least one first duration and / or at least one first offset) is not all included in one signaling, but is respectively carried by the first RRC signaling, and the first MAC signaling and / or the first PHY signaling. For example, part of the first information included in the first configuration information includes period information, and part of the first information included in the first MAC signaling and / or the first PHY signaling includes information for indicating the first time domain resources within a period (at least one first duration information and / or at least one first offset). first offset information), but the embodiments of the present application are not limited to this; for example, part of the first information included in the first configuration information includes periodic information and at least one first duration information, and the first MAC signaling and / or the first PHY signaling includes at least one first offset information; or, for example, part of the first information included in the first configuration information includes periodic information and at least one first duration information and at least one first offset information, the first MAC signaling and / or the first PHY signaling includes the at least one first duration information and one or more first duration information in the at least one first offset information, and one or more first duration information, and examples are not given one by one here.

[0110] In the above example, the first PHY signaling includes one or more first information fields, at least one of which is used to indicate the first time domain resource. The first information field includes a time domain resource allocation information field. The TDRA tables corresponding to different time domain resource allocation information fields may be the same or different. For details on how the first information field indicates the first time domain resource (first duration and / or first offset), please refer to the example description in "II" below.

[0111] It should be noted that the time units of the first duration information carried by the above first RRC signaling, and the first MAC signaling and / or the first PHY signaling are the same or different. For example, the time units of the first duration information corresponding to different beams are the same or different, or the time units of the first duration information carried by the first RRC signaling corresponding to the same beam are the same or different from the first duration information carried by the first PHY signaling. Examples are not given one by one here. The time units of the first offset information carried by the above first RRC signaling, and the first MAC signaling and / or the first PHY signaling are the same or different. For example, the time units of the first offset information corresponding to different beams are the same or different, or the time units of the first offset information carried by the first RRC signaling corresponding to the same beam are the same or different from the first offset information carried by the first PHY signaling. Examples are not given one by one here.

[0112] II. The first time domain resource is non-periodic

[0113] In some embodiments, the first indication information is carried by a first PHY signaling, and the first PHY signaling includes one or more first information fields, at least one first information field is used to indicate the first time domain resource. The first information field includes a time domain resource allocation information field. The TDRA tables corresponding to different time domain resource allocation information fields are the same or different, and the one or more first information fields are used to indicate at least one second duration information and / or at least one second offset information. For example, the first PHY signaling can be the aforementioned first DCI, and the forwarder receives the first DCI, and the first DCI includes one or more first indication information, wherein the first information for indicating the first time domain resource corresponding to the beam is indicated by the first information field included in the first DCI. However, the embodiments of the present application are not limited to this.

[0114] In some embodiments, a time domain resource allocation (TDRA) table (or simply a TDRA table) includes at least one row. For ease of description, a row is referred to as a TDRA configuration, i.e., the TDRA table includes at least one TDRA configuration. A TDRA configuration includes at least one time domain resource configuration, which includes at least a symbol position (starting symbol + length) configuration in a time slot. In addition, a TDRA configuration may also include at least one time slot offset K0 configuration, which may be included in or excluded from the time domain resource configuration. The TDRA configuration may also include other information (e.g., a mapping type), which may be included in or excluded from the time domain resource configuration. The embodiments of the present application are not limited thereto. Regarding the symbol position configuration in a time slot, for example, it includes a start and length indicator SLIV, which corresponds to a valid combination of a starting symbol (S) and a length (L), or, for example, corresponds to a starting symbol configuration and a length configuration, which are a valid combination.

[0115] For example, the first DCI includes one or more TDRA information fields, one TDRA information field indicates a row of TDRA configuration, and the TDRA tables corresponding to different time domain resource allocation information fields are the same or different.

[0116] For example, the first DCI includes a TDRA information field, and the TDRA information field (equivalent to the first information in the first indication information) is used to indicate the first time domain resource corresponding to the access link beam. Assuming that the first DCI can also be used to schedule the PDSCH / PUSCH of the NCR-MT, when the first DCI is used to schedule the PDSCH / PUSCH of the NCR-MT, the TDRA field is used to indicate the fourth time domain resource corresponding to the PDSCH / PUSCH. When the DCI is not used to schedule the PDSCH / PUSCH of the NCR-MT and is used to control the access link beam of the forwarding unit, the TDRA field is used to indicate the first time domain resource corresponding to the beam. In the two cases, the TDRA table corresponding to the TDRA information field is the same or different. That is, the TDRA table applied to the first time domain resource is the same or different from that applied to the fourth time domain resource.

[0117] For another example, the first DCI includes two TDRA fields, one for indicating the first time domain resource corresponding to the access link beam, and one for indicating the fourth time domain resource corresponding to the PDSCH / PUSCH of the NCR-MT. Thus, the first DCI can support the forwarding behavior of the forwarding unit (indicating the access link beam) for scheduling the PDSCH / PUSCH of the NCR-MT and controlling the forwarding unit at the same time.

[0118] For another example, the first DCI includes multiple TDRA fields, where at least two TDRA fields are used to indicate first time domain resources corresponding to the same or different beams indicated by the first DCI.

[0119] In the above example, the forwarder can support one or more of the above methods. The method may also include: the forwarder reports capability information to the network device, and the capability information is used to notify the network device of the information indication method supported by the forwarder. The network device can control its beam in the method supported by the forwarder according to the capability information.

[0120] In the above example, a TDRA information field (the bit value of the information field is the configured row number) is used to indicate a TDRA configuration, which is similar to the aforementioned first configuration information. The TDRA configuration (a first information) includes at least one second duration information and / or at least one second offset information of the first time domain resource. The second offset information may correspond to the aforementioned K0 configuration, and the second offset refers to the offset between the starting position of the first time domain resource and the ending position of the PDCCH carrying the first DCI. However, the embodiments of the present application are not limited to this. For example, the second offset may be the offset between the starting position of the first time domain resource corresponding to a beam and the ending position of the first time domain resource corresponding to the previous adjacent beam. The second duration information may correspond to the aforementioned SLIV configuration.

[0121] In some embodiments, a TDRA configuration may include at least one second duration information and / or at least one second offset information for a first time domain resource. The aforementioned second duration and / or second offset include at least one time unit, and the first information indicates the second duration and / or second offset by indicating the number of the time units. The at least one time unit is continuous in the time domain, or the at least one time unit is discontinuous in the time domain. The time unit is, for example, a subframe, a time slot, a symbol, a mini-slot, a millisecond, etc. That is, the second duration includes a millisecond-level duration and / or a time slot-level duration and / or a symbol-level duration, and the second offset includes a millisecond-level offset and / or a time slot-level offset and / or a symbol-level offset. The first time domain resource (the length of the time unit) is related to the subcarrier spacing. The time units of the above at least one second duration information are the same or different, and the time units of the above at least one second offset information are the same or different. Examples are not given one by one here. How to determine the first time domain resource based on the subcarrier spacing will be described later. The parts repeated in "I" will not be repeated.

[0122] Figures 8A to 8G are schematic diagrams of the first indication information of an embodiment of the present application. As shown in Figure 8A, the indicated beam is Beam#1, corresponding to a second offset and a second duration; as shown in Figure 8B, the indicated beams are Beam#1 and Beam#2, corresponding to a second offset and a second duration, and the specific second duration of each beam can be determined according to the implementation; as shown in Figure 8C, the indicated beams are Beam#1 and Beam#2, corresponding to a second offset and two second durations, and the two second durations correspond to Beam#1 and Beam#2 respectively; as shown in Figure 8D, the indicated beams are Beam#1 and Beam#2, corresponding to two second offsets and a second duration, and the two second offsets correspond to Beam#1 and Beam#2 respectively, the reference positions of the second offsets are the same, and the second durations of the two beams are the same; as shown in Figure 8E, the indicated beams are The beams are Beam#1 and Beam#2, corresponding to two second offsets and two second durations, the two second offsets correspond to Beam#1 and Beam#2 respectively, and the two second durations correspond to Beam#1 and Beam#2 respectively; as shown in FIG8F , the indicated beams are Beam#1 and Beam#2, corresponding to two second offsets and one second duration, the two second offsets correspond to Beam#1 and Beam#2 respectively, and Beam#1 and Beam#2 correspond to the same second duration; as shown in FIG8G , the indicated beams are Beam#1 and Beam#2, corresponding to two second offsets and two second durations, the two second offsets correspond to Beam#1 and Beam#2 respectively, and the two second durations correspond to Beam#1 and Beam#2 respectively. The difference between FIG8F , FIG8G and FIG8E is that the reference position of the second offset 2 is different.

[0123] The beams in Figures 8A to 8G above take Beam#1 and Beam#2 as examples, but this application is not limited to this and can also indicate other numbers of beams. In addition, the first time domain resources are continuous, but not limited to this, and can also be discontinuous (for example, one beam corresponds to multiple second offsets and / or second duration information, and thus discontinuous time domain resources can be configured).

[0124] In some cases, the first time domain resources corresponding to different beams indicated by the first indication information may overlap (partially or completely). For example, the received first RRC signaling includes multiple first configuration information (first indication information), and the first time domain resources corresponding to two or more beams among the beams indicated by different first indication information may overlap. However, the forwarder may not be able to use these two or more beams for forwarding at the same time. Therefore, the method also includes: the forwarder determines which beam should be used for the first time domain resources in the overlapping part according to the indication of the network device and / or a predefined method.

[0125] In some embodiments, the repeater may determine which beam should be used for the first time domain resource in the overlapping portion according to an instruction from the network device.

[0126] For example, the first indication information may further include priority information and / or identification information and / or grouping information. The forwarder forwards the signal using the beam indicated by the first indication information with the highest priority and / or the lowest identification. The identification may be determined based on the identification information and / or grouping information. For example, if the second beam associated with the first beam is grouped into the same group, the grouping information may be a group index, and the identification information may be an identifier of the second beam within the group, etc. Examples are not given here one by one.

[0127] The above is only an example. The priority information and / or identification information and / or grouping information may also not be included in the first indication information, but may be included in the fourth indication information sent separately by the network device. The embodiments of the present application are not limited to this.

[0128] In some embodiments, the repeater may determine which beam should be used for the first time domain resource in the overlapping portion according to a predefined rule.

[0129] For example, if the two or more beams include a first beam, the first beam is used. (The remaining beams may or may not be second beams associated with the first beam.)

[0130] For another example, the beam with the smallest index among the two or more beams mentioned above is used.

[0131] For another example, the two or more beams include multiple first beams, and the beam with the smallest index among the multiple first beams is used.

[0132] For another example, if multiple first indication information is included in the same list (multiple first configuration information is included in the same configuration list), the forwarder determines which beam to use based on the position / order of the first indication information in the list. For example, if one of the two or more beams is indicated by the first first indication information in the list, the beam indicated by the first first indication information is used; if one of the two or more beams is indicated by the second first indication information in the list and no beam is indicated by the first first indication information in the list, the beam indicated by the second first indication information is used, and so on.

[0133] (2) Second instruction information

[0134] In some embodiments, in order to enable the forwarder to have the function of controlling the forwarding function to be turned on / off, the forwarder can receive a second indication information for controlling the forwarding unit of the forwarder to be turned on and / or off. The second indication information can indicate whether the forwarding unit of the forwarder is in the on or off state in a certain time period (second time domain resource).

[0135] In some embodiments, the first indication information may be used as the second indication information, and the first indication information may be used to implicitly indicate the on and / or off status of the forwarding unit.

[0136] In some embodiments, the second indication information may include the first indication information and / or information indicating uplink and downlink directions, and the first indication information and / or information indicating uplink and downlink directions are used to implicitly indicate the on and / or off status of the forwarding unit.

[0137] For example, in the first time domain resource corresponding to the beam indicated by the above-mentioned first indication information, the forwarding unit is in the on state, and for other time domain resources, the forwarding unit is in the (default) off state, and / or, in the flexible time domain resource indicated by the information indicating the uplink and downlink directions, the forwarding unit is in the (default) off state; and / or, in the first time domain resource corresponding to the beam indicated by the first indication information, the time domain resource indicated as a flexible time domain resource by the information indicating the uplink and downlink directions, the forwarding unit is in the (default) off state.

[0138] In which, when the above-mentioned first indication information is used to implicitly indicate the on and / or off state of the forwarding unit, the first time domain resource indicated by the first information of the first indication information can also be referred to as the second time domain resource corresponding to the on (and / or off) state of the forwarding unit, and the above-mentioned first subcarrier spacing and / or second subcarrier spacing corresponding to the first time domain resource can also be said to be the third subcarrier spacing and / or fourth subcarrier spacing for the second time domain resource. The third subcarrier spacing and / or fourth subcarrier spacing will be described in detail later. In some embodiments, the second indication information includes third information for indicating the on and / or off state, and / or first information for indicating the on and / or off state of the corresponding second time domain resource.

[0139] For example, the second indication information only includes third information for indicating the on and / or off state. Based on the third information, the second time domain resource can be determined according to a predefined rule, or the starting position of the second time domain resource can be determined, and the forwarding unit is in the on and / or off state starting from the starting position until new second indication information is received, and then the corresponding action is performed according to the new second indication information.

[0140] For another example, the second indication information only includes the first information for indicating whether to turn on and / or turn off the corresponding second time domain resource. For example, the second indication information is only used to indicate the second time domain resource corresponding to the turned-on state or only used to indicate the second time domain resource corresponding to the turned-off state. In this way, there is no need to explicitly include the third information in the second indication information, and the turned-on and / or turned-off state can be determined based on the first information.

[0141] In some embodiments, the second indication information includes the aforementioned first indication information and the aforementioned third information (optionally, it may also include information indicating uplink and downlink directions).

[0142] For example, the third information is only used to indicate the closed state. In the first time domain resource (second time domain resource) corresponding to the beam indicated by the above-mentioned first indication information and not indicated as the closed state by the third information, the forwarding unit is in the open state. For other time domain resources, the forwarding unit is in the default closed state.

[0143] For another example, the third information is only used to indicate the closed state. In the first time domain resource (second time domain resource) corresponding to the beam indicated by the above-mentioned first indication information and (not indicated as the closed state by the third information and / or the information used to indicate the uplink and downlink directions is indicated as flexible), the forwarding unit is in the open state. For other time domain resources, the forwarding unit is in the default closed state.

[0144] In some embodiments, the second indication information is carried by at least one of a second RRC signaling, a second MAC signaling, or a second PHY signaling. The second PHY signaling may be a second DCI, such as a unicast DCI or a group common DCI. On the other hand, the format of the second DCI may be a traditional DCI format (e.g., 1_1, 2_0) or a newly introduced DCI format. The second RRC signaling and the first RRC signaling may be the same or different RRC signaling, the second MAC signaling and the first MAC signaling may be the same or different MAC signaling, the first PHY signaling and the second PHY signaling may be the same or different PHY signaling, and the embodiments of the present application are not limited thereto.

[0145] In some embodiments, the second time domain resource indicated in the second indication information (indicated by the first information) is periodic or semi-continuous (the former two can also be called semi-static) or non-periodic (or dynamic), or, accordingly, the time domain resource (second time domain resource) corresponding to the on and / or off state indicated in the second indication information is periodic or semi-continuous or non-periodic.

[0146] I. The second time domain resource is periodic or semi-persistent

[0147] In some embodiments, the second indication information is carried by the second RRC signaling, the second RRC signaling includes one or more second configuration information, and the second configuration information includes all information of the second indication information.

[0148] In some embodiments, the second indication information is carried by the second MAC signaling, the second MAC signaling includes one or more second configuration information, and the second configuration information includes all information of the second indication information.

[0149] In some embodiments, the second indication information is carried by the second RRC signaling + second MAC signaling and / or second PHY signaling, the second RRC signaling includes one or more second configuration information, the second configuration information includes all or part of the second indication information, the second MAC signaling and / or the second PHY signaling also includes identification information for indicating one or more second configurations among the multiple second configuration information and / or part of the second indication information.

[0150] In some embodiments, the second indication information is carried by the second MAC signaling + second PHY signaling, the second MAC signaling includes one or more second configuration information, the second configuration information includes all or part of the second indication information, and the second PHY signaling also includes identification information for indicating one or more second configurations among the multiple second configuration information and / or part of the second indication information.

[0151] The first information includes information and / or period information for indicating the second time domain resource within a period. The second configuration information includes all or part of the first information for indicating the second time domain resource, and the second MAC signaling and / or the second PHY signaling includes part of the first information.

[0152] Part of the first information included in the second configuration information includes period information, and part of the first information included in the second MAC signaling and / or the second PHY signaling includes information used to indicate second time domain resources within a period.

[0153] The information indicating the second time domain resource within a period includes at least one third duration information and / or at least one third offset information; the third duration includes a millisecond-level duration and / or a slot-level duration and / or a symbol-level duration; and the third offset includes a millisecond-level offset and / or a slot-level offset and / or a symbol-level offset.

[0154] The following example illustrates this.

[0155] In some embodiments, the second indication information may be carried by second RRC signaling.

[0156] The second RRC signaling may include one or more second configuration information, and the second configuration information includes all the information of the second indication information, that is, the forwarder can receive one or more second indication information carried by the second RRC signaling. The first information included in a second indication information may include information and / or period information for indicating the second time domain resource within a period. Among them, the information for indicating the second time domain resource within a period includes at least one third duration information and / or at least one third offset information of the second time domain resource. For example, the first information may include a period information, one or more third offset information, and one or more third duration information. Among them, the open state and / or the closed state corresponds to one or more third offset information and / or one or more third duration information, the open state and / or the closed state corresponds to the same or different third offset information, and / or the open state and / or the closed state corresponds to the same or different third duration information. The aforementioned third offset refers to the offset between the starting position of the time domain resource corresponding to the on and / or off state within a period and the reference position. The reference position can be the starting position of the system frame after the second RRC signaling is received, or the end position of the time domain resource corresponding to other on and / or off states, etc., but the embodiments of the present application are not limited to this.

[0157] In some embodiments, the aforementioned period and / or third duration and / or third offset includes at least one time unit, and the first information indicates the aforementioned period and / or third duration and / or third offset by indicating the number of the time units. The at least one time unit is continuous in the time domain, or the at least one time unit is discontinuous in the time domain. The time unit is, for example, a subframe, a time slot, a symbol, a mini-slot, a millisecond, etc. That is, the period includes a millisecond-level period and / or a time slot-level period and / or a symbol-level period, the third duration includes a millisecond-level duration and / or a time slot-level duration and / or a symbol-level duration, and the third offset includes a millisecond-level offset and / or a time slot-level offset and / or a symbol-level offset. The second time domain resource (the length of the time unit) is related to the subcarrier spacing. How to determine the second time domain resource based on the subcarrier spacing will be described later.

[0158] Figures 7A to 7G are schematic diagrams of the second indication information of an embodiment of the present application. As shown in Figure 7A, the indicated second time domain resource is in the closed state, corresponding to a third offset and a third duration; as shown in Figure 7B, the second time domain resource corresponding to the open state and the second time domain resource corresponding to the closed state are respectively indicated, corresponding to a third offset and a third duration, and the specific third duration of each state can be determined according to the implementation; as shown in Figure 7C, the second time domain resource corresponding to the open state and the second time domain resource corresponding to the closed state are respectively indicated, corresponding to a third offset and two third durations, and the two third durations correspond to the closed state and the open state respectively; as shown in Figure 7D, the second time domain resource corresponding to the open state and the second time domain resource corresponding to the closed state are respectively indicated, corresponding to two third offsets and a third duration, and the two third offsets correspond to the closed state and the open state respectively, and the reference position of the third offset is the same, and the third of the closed state and the open state are the same. The duration is the same; as shown in Figure 7E, the second time domain resource corresponding to the on state and the second time domain resource corresponding to the off state are respectively indicated, corresponding to two third offsets and two third durations, the two third offsets correspond to the off state and the on state respectively, and the two third durations correspond to the off state and the on state respectively; as shown in Figure 7F, the second time domain resource corresponding to the on state and the second time domain resource corresponding to the off state are respectively indicated, corresponding to two third offsets and one third duration, the two third offsets correspond to the off state and the on state respectively, and the off state and the on state correspond to the same third duration; as shown in Figure 7G, the second time domain resource corresponding to the on state and the second time domain resource corresponding to the off state are respectively indicated, corresponding to two third offsets and two third durations, the two third offsets correspond to the off state and the on state respectively, and the two third durations correspond to the off state and the on state respectively. The difference from Figure 7E is that the reference position of the third offset 2 is different.

[0159] The second time domain resources corresponding to Figures 7A to 7G above in one cycle are continuous, but not limited to this, and can also be discontinuous (for example, an on and / or off state corresponds to multiple third offsets and / or third duration information, and then discontinuous time domain resources can be configured).

[0160] The one or more second indication information are included in an information element / field (IE / field) of the second RRC signaling. The IE / field may be forwarder-specific, i.e., the IE / field is applicable only to the forwarder and is used to control the forwarding unit of the forwarder. The IE / field may also include the first indication information and / or the third indication information. The information element / field may be the same as or different from the information element / field in (1), and the embodiments of the present application are not limited thereto.

[0161] In some embodiments, the second indication information is carried by a second RRC signaling, a second MAC signaling, and / or a second PHY signaling. The implementation of the second RRC signaling is as described above. The second MAC signaling and / or the second PHY signaling is used to activate and / or deactivate one or more second configurations in the multiple second configuration information. For example, the second MAC signaling and / or the second PHY signaling also includes identification information for indicating one or more second configurations in the multiple second configuration information.

[0162] For example, the second RRC signaling includes multiple second configuration information, the identification information in the second MAC signaling and / or the second PHY signaling is the second configuration corresponding to the activated one or more second indication information, and the forwarder turns on and / or turns off the forwarding unit according to the time domain resources corresponding to the activated second configuration. For example, the second RRC signaling includes 8 second configuration information, and the second MAC signaling is 00000010, then the seventh second configuration information is activated, and examples are not given one by one here. Figure 9 is a schematic diagram of the second indication information of an embodiment of the present application. As shown in Figure 9, the second indication information is carried by the second RRC signaling and the second MAC signaling, the seventh second configuration information is activated, and the forwarding unit is turned on and / or turned off according to the corresponding time domain resources in the seventh second configuration information. The seventh second configuration includes two third offsets and two third durations, which correspond to the on state and the off state respectively.

[0163] In some embodiments, when the second PHY signaling is used for activation, it may be directly activated based on the second RRC signaling configuration, or activated based on further configuration of the second MAC signaling (ie, activated and / or deactivated through MAC CE and DCI).

[0164] In some embodiments, the second indication information is carried by second MAC signaling and second PHY signaling, the second MAC signaling includes one or more second configuration information, the specific implementation of the second configuration information is similar to that of the second RRC signaling, and the second PHY signaling is used to activate and / or deactivate one or more second configurations in the multiple second configuration information. The second PHY signaling also includes identification information for indicating one or more second configurations in the multiple second configuration information. The forwarder turns on and / or off the forwarding unit according to the activated configuration.

[0165] In some embodiments, the second indication information is carried by a second RRC signaling, a second MAC signaling and / or a second PHY signaling. The difference from the aforementioned embodiment is that the various information of the first information (period and / or at least one third duration and / or at least one third offset) are not all included in one signaling, but are respectively carried by the second RRC signaling, and the second MAC signaling and / or the second PHY signaling. For example, part of the first information included in the second configuration information includes period information, and part of the first information included in the second MAC signaling and / or the second PHY signaling includes information for indicating the second time domain resources within a period (at least one third duration information and / or at least one third offset). third offset information), but the embodiments of the present application are not limited to this; for example, part of the first information included in the second configuration information includes periodic information and at least one second duration information, and the second MAC signaling and / or the second PHY signaling includes at least one third offset information; or, for example, part of the first information included in the second configuration information includes periodic information and at least one third duration information and at least one third offset information, the second MAC signaling and / or the second PHY signaling includes the at least one third duration information and one or more third duration information in the at least one third offset information, and one or more third duration information, and examples are not given one by one here.

[0166] In the above example, the second PHY signaling includes one or more second information fields, at least one of which is used to indicate the second time domain resource. The second information field includes a time domain resource allocation information field. The TDRA tables corresponding to different time domain resource allocation information fields may be the same or different. For details on how the second information field indicates the second time domain resource (third duration and / or third offset), please refer to the example description in "II" below.

[0167] It should be noted that the time units of the third duration information carried by the above second RRC signaling, and the second MAC signaling and / or the second PHY signaling are the same or different. For example, the time units of the third duration information corresponding to different beams are the same or different, or the time units of the third duration information carried by the second RRC signaling corresponding to the same beam are the same or different from the third duration information carried by the second PHY signaling. Examples are not given one by one here. The time units of the third offset information carried by the above second RRC signaling, and the second MAC signaling and / or the second PHY signaling are the same or different. For example, the time units of the third offset information corresponding to different beams are the same or different, or the time units of the third offset information carried by the second RRC signaling corresponding to the same beam are the same or different from the third offset information carried by the second PHY signaling. Examples are not given one by one here.

[0168] II. The second time domain resource is non-periodic

[0169] In some embodiments, the second indication information is carried by a second PHY signaling, and the second PHY signaling includes one or more second information fields, at least one second information field is used to indicate the second time domain resource. The second information field includes a time domain resource allocation information field. The TDRA tables corresponding to different time domain resource allocation information fields are the same or different, and the one or more second information fields are used to indicate at least one fourth duration information and / or at least one fourth offset information. For example, the second PHY signaling can be the aforementioned second DCI (the second DCI can be the first DCI or a DCI different from the first DCI), and the repeater receives the second DCI, which includes one or more second indication information, wherein the first information for indicating the second time domain resource corresponding to the beam is indicated by the second information field included in the second DCI. However, the embodiments of the present application are not limited to this.

[0170] For example, the second DCI includes one or more TDRA information fields, one TDRA information field indicates a row of TDRA configuration, and the TDRA tables corresponding to different time domain resource allocation information fields are the same or different.

[0171] For example, the second DCI includes a TDRA information field, and the TDRA information field (equivalent to the first information in the second indication information) is used to indicate the second time domain resource corresponding to the on and / or off state. Assuming that the second DCI can also be used to schedule the PDSCH / PUSCH of the NCR-MT, when the second DCI is used to schedule the PDSCH / PUSCH of the NCR-MT, the TDRA field is used to indicate the fourth time domain resource corresponding to the PDSCH / PUSCH. When the DCI is not used to schedule the PDSCH / PUSCH of the NCR-MT and is used to control the forwarding behavior of the forwarding unit (indicating that the forwarding unit is on and / or off), the TDRA field is used to indicate the second time domain resource corresponding to the forwarding unit being on and / or off. In the two cases, the TDRA table corresponding to the TDRA information field is the same or different. That is, the TDRA table applied to the second time domain resource is the same or different from that applied to the fourth time domain resource.

[0172] For another example, the second DCI includes two TDRA fields, one for indicating the second time domain resource corresponding to the forwarding unit being on and / or off, and one for indicating the fourth time domain resource corresponding to the PDSCH / PUSCH of the NCR-MT. Thus, the second DCI can support both the PDSCH / PUSCH for scheduling the NCR-MT and the forwarding behavior of the control forwarding unit (indicating that the forwarding unit is on and / or off).

[0173] For another example, the second DCI includes two TDRA fields, one for indicating the second time domain resource corresponding to the forwarding unit being turned on and / or off, and one for indicating the first time domain resource corresponding to the access link beam. In both cases, the TDRA tables corresponding to the TDRA information fields are the same or different. That is, the TDRA table applied to the second time domain resource is the same as or different from that applied to the first time domain resource.

[0174] In the above example, the forwarder can support one or more of the above methods, and the method may also include: the forwarder reports capability information to the network device, and the capability information is used to notify the network device of the information indication method supported by the forwarder. The network device can control the on and / or off status of its forwarding unit in the method supported by the forwarder according to the capability information.

[0175] In some embodiments, the second indication information included in the second DCI only includes the third information, which is used to indicate that the forwarding unit is in a closed state, and the priority of the closed state indicated thereby is higher than the priority of the open state implicitly indicated by the first indication information carried by the first RRC signaling and / or the first MAC signaling, and / or, is lower than the priority of the open state implicitly indicated by the first indication information carried by the first DCI.

[0176] In some embodiments, if the DCI includes the first indication information, the second indication information cannot be included, or vice versa. In other words, including both the first indication information and the second indication information in the DCI is an incorrect configuration, and the network device should avoid such a configuration.

[0177] In the above example, a TDRA information field (the bit value of the information field is the configured row number) is used to indicate a TDRA configuration, which is similar to the aforementioned second configuration information. The TDRA configuration (a first information) includes at least one fourth duration information and / or at least one fourth offset information of the second time domain resource. The fourth offset information may correspond to the aforementioned K0 configuration, and the fourth offset refers to the offset between the starting position of the second time domain resource and the ending position of the PDCCH carrying the second DCI. However, the embodiments of the present application are not limited to this. For example, the fourth offset may be the offset between the starting position of the second time domain resource corresponding to a state and the ending position of the second time domain resource corresponding to the previous adjacent state. The fourth duration information may correspond to the aforementioned SLIV configuration.

[0178] In some embodiments, a TDRA configuration may include at least one fourth duration information and / or at least one fourth offset information for a second time domain resource. The aforementioned fourth duration and / or fourth offset include at least one time unit, and the first information indicates the fourth duration and / or fourth offset by indicating the number of the time units. The at least one time unit is continuous in the time domain, or the at least one time unit is discontinuous in the time domain. The time unit is, for example, a subframe, a time slot, a symbol, a mini-slot, a millisecond, etc. That is, the fourth duration includes a millisecond-level duration and / or a time slot-level duration and / or a symbol-level duration, and the fourth offset includes a millisecond-level offset and / or a time slot-level offset and / or a symbol-level offset. The second time domain resource (the length of the time unit) is related to the subcarrier spacing. The time units of the above at least one fourth duration information are the same or different, and the time units of the above at least one fourth offset information are the same or different. How to determine the second time domain resource based on the subcarrier spacing will be described later. The parts repeated in "I" will not be repeated.

[0179] Figures 10A to 10G are schematic diagrams of the second indication information of an embodiment of the present application. As shown in Figure 10A, the indicated state is the open state, corresponding to a fourth offset and a fourth duration; as shown in Figure 10B, the indicated states are the open state and the closed state, corresponding to a fourth offset and a fourth duration, and the specific fourth duration of each state can be determined according to the implementation; as shown in Figure 10C, the indicated states are the open state and the closed state, corresponding to a fourth offset and two fourth durations, and the two fourth durations correspond to the open state and the closed state respectively; as shown in Figure 10D, the indicated states are the open state and the closed state, corresponding to two fourth offsets and a fourth duration, and the two fourth offsets correspond to the open state and the closed state respectively, the reference position of the fourth offset is the same, and the fourth duration of the two states is the same; As shown in FIG. 10E, the indicated states are the on state and the off state, corresponding to two fourth offsets and two fourth time lengths, the two fourth offsets correspond to the on state and the off state respectively, and the two fourth time lengths correspond to the on state and the off state respectively; as shown in FIG. 10F, the indicated states are the on state and the off state, corresponding to two fourth offsets and one fourth time length, the two fourth offsets correspond to the on state and the off state respectively, and the on state and the off state correspond to the same fourth time length; as shown in FIG. 10G, the indicated states are the on state and the off state, corresponding to two fourth offsets and two fourth time lengths, the two fourth offsets correspond to the on state and the off state respectively, and the two fourth time lengths correspond to the on state and the off state respectively. The difference between FIG. 10F, FIG. 10G and FIG. 10E is that the reference position of the fourth offset 2 is different.

[0180] The second time domain resources in the above Figures 10A to 10G are continuous, but not limited to this, and can also be discontinuous (for example, one state corresponds to multiple fourth offsets and / or fourth duration information, and then discontinuous time domain resources can be configured).

[0181] In some cases, the second time domain resources corresponding to the on and / or off states indicated by the second indication information may overlap (partially or completely). For example, the received second RRC signaling includes multiple pieces of second configuration information (second indication information), and the second time domain resources corresponding to the on and / or off states indicated by different second indication information may overlap. Therefore, the method further includes: the forwarder determining whether the second time domain resources in the overlapping portion are in the on or off state based on the indication of the network device and / or a predefined method.

[0182] In some embodiments, the repeater may determine whether the second time domain resource in the overlapping portion is in an on state or a off state according to an instruction from the network device.

[0183] For example, the second indication information may further include priority information and / or identification information and / or grouping information. The forwarder adopts the state indicated by the second indication information with the highest priority and / or the smallest identification. The identification may be determined based on the identification information and / or grouping information.

[0184] The above is only an example. The priority information and / or identification information and / or grouping information may also not be included in the second indication information, but may be included in the fourth indication information sent separately by the network device. The embodiments of the present application are not limited to this.

[0185] In some embodiments, the repeater may determine whether the second time domain resource in the overlapping portion should be in an on state or a off state according to a predefined rule.

[0186] For example, as long as one of the plurality of second indication information that cause the overlap indicates an on state, the forwarding unit is in an on state.

[0187] For another example, if the plurality of second indication information (second configuration information) that results in the above overlap is included in the same list (the same configuration list), the forwarder determines which indication to use based on the position / order of the second indication information in the list. For example, if the plurality of second indication information includes the first second indication information in the list, the state indicated by the first second indication information shall prevail; if the plurality of second indication information includes the second second indication information in the list but does not include the first second indication information in the list, the state indicated by the second second indication information shall prevail, and so on.

[0188] (3) Third instruction information

[0189] In some embodiments, the backhaul link beam may also be referred to as a network device side beam, which refers to the receive beam / transmit beam adopted (used) by the repeater in the BH link, wherein the beam (of the antenna) refers, for example, to the main lobe of the radiation pattern of the antenna array. The implementation method of the beam is similar to that of the AC link beam. For details, please refer to (1).

[0190] In some embodiments, the third indication information includes backhaul link beam indication information, and / or identification information, and / or grouping information, and / or priority information, and / or first information for indicating the third time domain resource corresponding to the backhaul link beam.

[0191] In some embodiments, the third indication information is carried by at least one of a third RRC signaling, a third MAC signaling, or a third PHY signaling. The third PHY signaling may be a third DCI, such as a unicast DCI or a group common DCI. On the other hand, the format of the third DCI may be a traditional DCI format (e.g., 1_1, 2_0) or a newly introduced DCI format. The third RRC signaling, the third MAC signaling, or the third PHY signaling may be the same as or different from the aforementioned first RRC signaling, the first MAC signaling, or the first PHY signaling, the second RRC signaling, the second MAC signaling, or the second PHY signaling.

[0192] The various information and carrying implementation methods in the third indication information are similar to those in the first indication information and will not be described in detail here.

[0193] For example, when the third time domain resource is periodic or semi-persistent, the first information includes information indicating the third time domain resource within a period and / or period information. The information indicating the third time domain resource within a period includes at least one fifth duration information and / or fifth offset information of the third time domain resource.

[0194] For example, when the third time domain resource is non-periodic, the first information includes at least one sixth duration information and / or at least one sixth offset information for indicating the third time domain resource.

[0195] In some embodiments, the aforementioned period and / or fifth duration and / or fifth offset and / or sixth duration and / or sixth offset include at least one time unit, and the first information indicates the aforementioned period and / or fifth duration and / or fifth offset and / or sixth duration and / or sixth offset by indicating the number of the time units. The at least one time unit is continuous in the time domain, or the at least one time unit is discontinuous in the time domain. The time unit is, for example, a subframe, a time slot, a symbol, a mini-slot, a millisecond, etc. That is, the fifth duration and / or sixth duration includes a millisecond-level duration and / or a time slot-level duration and / or a symbol-level duration, and the fifth offset and / or sixth offset includes a millisecond-level offset and / or a time slot-level offset and / or a symbol-level offset. The third time domain resource (the length of the time unit) is related to the subcarrier spacing.

[0196] (IV) Subcarrier spacing correlation

[0197] In the aforementioned embodiment, the time unit of the first duration and / or period and / or second duration corresponding to the first time domain resource is related to the first subcarrier spacing, the time unit of the first offset and / or second offset corresponding to the first time domain resource is related to the second subcarrier spacing, the time unit of the third duration and / or period and / or fourth duration corresponding to the second time domain resource is related to the third subcarrier spacing, the time unit of the third offset and / or fourth offset corresponding to the second time domain resource is related to the fourth subcarrier spacing, the time unit of the fifth duration and / or period and / or sixth duration corresponding to the third time domain resource is related to the fifth subcarrier spacing, and the time unit of the fifth offset and / or sixth offset corresponding to the third time domain resource is related to the sixth subcarrier spacing.

[0198] In some embodiments, the forwarder determines the time domain resource based on the subcarrier spacing, wherein the first subcarrier spacing and / or the second subcarrier spacing is used to determine the first time domain resource, the third subcarrier spacing and / or the fourth subcarrier spacing is used to determine the second time domain resource, and the fifth subcarrier spacing and / or the sixth subcarrier spacing is used to determine the third time domain resource.

[0199] In some embodiments, in order for the forwarder to determine the aforementioned time domain resources, the forwarder needs to determine which subcarrier spacing the time unit of the time domain resources is based on, and the subcarrier spacing (including the first subcarrier spacing and / or the second subcarrier spacing and / or the third subcarrier spacing and / or the fourth subcarrier spacing and / or the fifth subcarrier spacing and / or the sixth subcarrier spacing) is predefined or indicated by second information sent by the network device. The first subcarrier spacing and / or the second subcarrier spacing and / or the third subcarrier spacing and / or the fourth subcarrier spacing and / or the fifth subcarrier spacing and / or the sixth subcarrier spacing are the same or different.

[0200] In some embodiments, the first subcarrier spacing and / or the second subcarrier spacing and / or the third subcarrier spacing and / or the fourth subcarrier spacing and / or the fifth subcarrier spacing and / or the sixth subcarrier spacing are determined according to communication standard definition rules, including: the first subcarrier spacing and / or the second subcarrier spacing and / or the third subcarrier spacing and / or the fourth subcarrier spacing and / or the fifth subcarrier spacing and / or the sixth subcarrier spacing are fixed, or are the reference subcarrier spacing of the TDD configuration, or are the subcarrier spacing of the uplink / downlink activation BWP of the repeater, or carry the aforementioned indication information The subcarrier spacing of the PDSCH / PDCCH that carries all or part of the information in the aforementioned indication information, or the subcarrier spacing of the PUCCH of the HARQ feedback of the PDSCH / PDCCH used to carry all or part of the information in the aforementioned indication information, or the maximum or minimum value of the subcarrier spacing of the uplink / downlink configuration BWP of the forwarder, or the maximum or minimum value of the subcarrier spacing of the SSB, or the maximum or minimum value of the subcarrier spacing of the PRACH, or the maximum or minimum value of the subcarrier spacing of the uplink / downlink carrier, or the maximum or minimum value of at least two of the above subcarrier spacings.

[0201] In some embodiments, the reference subcarrier spacing of the TDD configuration is, for example, predefined or configured by high-level signaling. The TDD configuration includes, for example, a semi-static TDD configuration and / or a dynamic TDD configuration. For example, the semi-static TDD configuration is provided by a network device through high-level signaling at the cell level / user-specific level (for example, tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated). For another example, the dynamic TDD configuration is provided by SFI / DCI format 2_0 (DCI format 2_0 includes SFI). A time unit (eg symbol, time slot, subframe) can be configured as uplink, downlink or flexible. Among them, if a time unit is semi-statically configured as uplink, it cannot be rewritten as downlink or flexible by SFI / DCI format 2_0 (even if SFI / DCI format 2_0 indicates that the time unit is downlink or flexible). Similarly, if a time unit is semi-statically configured as downlink, it cannot be rewritten as uplink or flexible by SFI / DCI format 2_0 (even if SFI / DCI format 2_0 indicates that the time unit is uplink or flexible). If a time unit is configured as flexible by the above-mentioned higher-layer signaling or is not configured as uplink or downlink by the above-mentioned higher-layer signaling (default is flexible), SFI / DCI format 2_0 can configure the time unit as uplink, downlink, or flexible.

[0202] In some embodiments, the reference subcarrier spacing for the TDD configuration includes the reference subcarrier spacing for the semi-static TDD configuration and / or the reference subcarrier spacing for the dynamic TDD configuration. The subcarrier spacing for the semi-static TDD configuration and the dynamic TDD configuration may be the same or different. The subcarrier spacing for the semi-static TDD configuration and the dynamic TDD configuration may be configured using different higher-layer signaling, such as different RRC IEs / fields.

[0203] In some embodiments, the subcarrier spacing of the TDD configuration includes a subcarrier spacing for downlink and / or a subcarrier spacing for uplink. For example, for FDD, when the mobile terminal does not support simultaneously receiving downlink signals on the downlink carrier of the FDD frequency band and sending uplink signals on the uplink carrier of the FDD frequency band, the above-mentioned TDD configuration is also applicable (not limited thereto), and the above-mentioned high-layer signaling and / or SFI / DCI format 2_0 are used to indicate that the mobile terminal receives downlink signals on the downlink carrier or sends uplink signals on the uplink carrier within one time unit. At this time, the reference subcarrier spacing for downlink and uplink is the same or different.

[0204] In some embodiments, the first subcarrier spacing and / or the second subcarrier spacing and / or the third subcarrier spacing and / or the fourth subcarrier spacing and / or the fifth subcarrier spacing and / or the sixth subcarrier spacing is a reference subcarrier spacing of the TDD configuration (that is, the same as the reference subcarrier spacing of the TDD configuration), and for indication information carried by different signaling (or beam / switch configurations with different time domain characteristics), the corresponding reference subcarrier spacing of the TDD configuration is different. For example, for the first indication information carried only by RRC signaling (or the semi-static access link beam configuration), the first subcarrier spacing and / or the second subcarrier spacing is the reference subcarrier spacing of the semi-static TDD configuration. For another example, for the first indication information carried by DCI (or dynamic access link beam configuration), the first subcarrier spacing and / or the second subcarrier spacing is the reference subcarrier spacing for the dynamic TDD configuration; or, for example, for the second indication information carried only by RRC signaling (or semi-static on / off configuration), the third subcarrier spacing and / or the fourth subcarrier spacing is the reference subcarrier spacing for the semi-static TDD configuration. For another example, for the second indication information carried by DCI (or dynamic on / off configuration), the third subcarrier spacing and / or the fourth subcarrier spacing is the reference subcarrier spacing for the dynamic TDD configuration; or, for example, for the third indication information carried only by RRC signaling (or semi-static backhaul link beam configuration), the fifth subcarrier spacing and / or the sixth subcarrier spacing is the reference subcarrier spacing for the semi-static TDD configuration. For another example, for the third indication information carried by DCI (or dynamic backhaul link beam configuration), the fifth subcarrier spacing and / or the sixth subcarrier spacing is the reference subcarrier spacing for the dynamic TDD configuration.

[0205] In some embodiments, the first subcarrier spacing and / or the second subcarrier spacing and / or the third subcarrier spacing and / or the fourth subcarrier spacing and / or the fifth subcarrier spacing and / or the sixth subcarrier spacing are indicated by second information sent by a network device, and the second information includes one or more subcarrier spacing indication information, and the one or more subcarrier spacing indication information is used to indicate the first subcarrier spacing and / or the second subcarrier spacing and / or the third subcarrier spacing and / or the fourth subcarrier spacing and / or the fifth subcarrier spacing and / or the sixth subcarrier spacing.

[0206] In some embodiments, for the first subcarrier spacing and / or the second subcarrier spacing, one first subcarrier spacing indication information and / or one second subcarrier spacing indication information corresponds to one beam or to multiple beams, or corresponds to one first indication information (access link beam indication information) or to multiple first indication information (access link beam indication information).

[0207] For example, a first subcarrier spacing indication information and / or a second subcarrier spacing indication information is applied to an access link indication information (or a first indication information), wherein an access link indication information (or a first indication information) indicates one or more beams, and the one or more beams all apply a first subcarrier spacing indication information and / or a second subcarrier spacing indication information, that is, the first duration and / or second duration of the first time domain resource corresponding to the one or more beams apply the same first subcarrier spacing indication information, and the first offset and / or second offset of the first time domain resource corresponding to the one or more beams are the same. The offset applies the same second subcarrier spacing indication information; wherein, the first subcarrier spacing indication information and / or the second subcarrier spacing indication information can be included in the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling, or included in the first indication information (access link beam indication information) of the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling, or included in the fourth RRC signaling and / or the fourth MAC signaling and / or the fourth PHY signaling that are different from the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling. For example, each first indication information (access link beam indication information) includes a first subcarrier spacing indication information and / or a second subcarrier spacing indication information, or the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling includes multiple (N) first subcarrier spacing indication information and / or multiple (N) second subcarrier spacing indication information, which respectively correspond to the multiple (N) first indication information (access link beam indication information) in the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling.

[0208] For example, a first subcarrier spacing indication information and / or a second subcarrier spacing indication information is applied to an access link beam, wherein an access link indication information (or a first indication information) indicates multiple beams, and the multiple beams all apply different first subcarrier spacing indication information and / or different second subcarrier spacing indication information, that is, the first duration and / or second duration of the first time domain resources corresponding to the multiple beams apply different first subcarrier spacing indication information, and the first offset and / or second offset of the first time domain resources corresponding to the multiple beams apply different second subcarrier spacing indication information. indication information; wherein, the different first subcarrier spacing indication information and / or the different second subcarrier spacing indication information may both be included in the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling, or both are included in the first indication information (access link beam indication information) of the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling, or are included in a fourth RRC signaling and / or the fourth MAC signaling and / or the fourth PHY signaling that is different from the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling. For example, each first indication information (access link beam indication information) includes multiple first subcarrier spacing indication information and / or multiple second subcarrier spacing indication information, or the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling include multiple first subcarrier spacing indication information and / or multiple second subcarrier spacing indication information, which respectively correspond to the multiple beams indicated by the first indication information (access link beam indication information) in the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling.

[0209] For example, a first subcarrier spacing indication information and / or a second subcarrier spacing indication information is applied to one or more access link beam indication information (first indication information), wherein an access link indication information (or a first indication information) indicates one or more beams, and the one or more access link beam indication information (first indication information) all apply a first subcarrier spacing indication information and / or a second subcarrier spacing indication information, that is, the first duration and / or second duration of the first time domain resource corresponding to the multiple beams indicated by the multiple first indication information in the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling apply the same first subcarrier spacing indication information. Carrier spacing indication information, the first offset and / or second offset of the first time domain resources corresponding to the multiple beams indicated by the multiple first indication information in the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling apply the same second subcarrier spacing indication information; wherein, the first subcarrier spacing indication information and / or the second subcarrier spacing indication information can be included in the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling, or included in a fourth RRC signaling and / or the fourth MAC signaling and / or the fourth PHY signaling that is different from the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling. For example, the first (fourth) RRC signaling and / or the first (fourth) MAC signaling and / or the first (fourth) PHY signaling include a first subcarrier spacing indication information and / or a second subcarrier spacing indication information, and the first indication information (access link beam indication information) indicated by the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling all applies the first subcarrier spacing indication information and / or the second subcarrier spacing indication information.

[0210] In some embodiments, for the third subcarrier spacing and / or the fourth subcarrier spacing, one third subcarrier spacing indication information and / or one fourth subcarrier spacing indication information corresponds to the on and / or off state, or corresponds to one second indication information or corresponds to multiple second indication information.

[0211] For example, a third subcarrier spacing indication information and / or a fourth subcarrier spacing indication information is applied to a state, wherein multiple second indication information indicates an on and / or off state, the on state corresponds to a third subcarrier spacing indication information and / or a fourth subcarrier spacing indication information, and the off state corresponds to a third subcarrier spacing indication information and / or a fourth subcarrier spacing indication information, that is, the third duration and / or fourth duration of the second time domain resource corresponding to the on state applies a third subcarrier spacing indication information, and the third duration and / or fourth duration of the second time domain resource corresponding to the off state applies another third subcarrier spacing indication information.

For example, the second (fourth) RRC signaling and / or the second (fourth) MAC signaling and / or the second (fourth) PHY signaling includes a third subcarrier spacing indication information and / or a fourth subcarrier spacing indication information, and the second indication information indicated based on the second RRC signaling and / or the second MAC signaling and / or the second PHY signaling all applies the third subcarrier spacing indication information and / or the fourth subcarrier spacing indication information.
