Description

[Technical Field]

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

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

[0003] Therefore, 5G systems will be deployed in new spectrum in addition to traditional telecommunications spectrum, with frequencies in the new spectrum having significantly higher frequencies than the traditional telecommunications spectrum used by 3G and 4G systems. For example, 5G systems may be deployed in millimeter wave bands (such as 28 GHz, 38 GHz, 60 GHz and above).

[0004] According to the wireless signal propagation rules, the higher the carrier frequency of the wireless signal, the greater the signal fading during propagation. Therefore, in actual deployment, the 5G system needs to strengthen cell coverage compared to traditional 3G and 4G systems. Especially for 5G systems deployed in the millimeter wave band, how to better strengthen the cell coverage of the 5G system has become an urgent issue that needs to be resolved.

[0005] The above description of the background art is merely for the purpose of explaining the configuration of the present invention more clearly and completely, and is provided for the understanding of those skilled in the art. These configurations described in the background art of the present invention should not be construed as being well known to those skilled in the art. Summary of the Invention [Problem to be solved by the invention]

[0006] In order to better solve the coverage problem of cellular mobile communication systems in practical deployments, using a radio frequency repeater (RF relay / repeater) to amplify and forward communication signals between terminal devices and network devices is a relatively commonly used deployment method. Radio frequency repeaters are relatively widely applied in practical deployments of 3G systems and 4G systems. Generally, a radio frequency repeater is a device that amplifies and forwards signals between devices in the radio frequency domain. In other words, a radio frequency repeater is a non-regenerative relay node that only directly amplifies and forwards all received signals.

[0007] According to the inventors' findings, enhancing coverage using conventional radio frequency repeaters is one viable solution to the coverage problem in the deployment of 5G systems. However, the forwarding operation of conventional radio frequency repeaters is network-independent. The effect of amplifying the forwarded signal is insufficient, and it may cause significant interference to other devices in the network, increasing the system's noise and interference levels and reducing network throughput. Specifically, taking antenna direction as an example, 5G systems use more advanced and complex MIMO (multiple-input, multiple-output) technology compared to 3G and 4G systems. In 5G systems, directional antennas are a basic component of network equipment and terminal devices, especially for high carrier frequencies, and signal transmission and reception based on beamforming technology is the basic signal transmission method in 5G systems. The direction and width of the (simulated) beams of network equipment and terminal devices may change dynamically due to changes in position (i.e., beam switching). However, the antennas of conventional radio frequency repeaters cannot dynamically adjust their direction, their beams are wider, and the beam direction and width of their transmitting and receiving antennas cannot flexibly adapt to dynamic changes in the location of network devices and terminal devices and the beam direction and width of the transmitting and receiving antennas. When such radio frequency repeaters are deployed in 5G systems, the beam direction and width of their transmitting and receiving antennas may not match the dynamic changes in the beam direction and width of the transmitting and receiving antennas of the network devices and terminal devices, resulting in insufficient performance / effectiveness of the amplified / enhanced target signals. In addition, using a wider transmitting beam may cause significant interference to other devices (e.g., network devices or terminal devices) within a wider range, increasing noise and interference levels throughout the system and reducing network throughput.

[0008] In view of at least one of the above problems, embodiments of the present invention provide an information indication method, a repeater, and a network device. [Means for solving the problem]

[0009] In one aspect of an embodiment of the present invention, there is provided an information indication method applied to a repeater, the method including the steps of: a mobile terminal of the repeater receiving indication information for controlling a forwarding unit of the repeater, the indication information including first information for indicating a time domain resource, the time domain resource being related to a subcarrier spacing.

[0010] Another aspect of an embodiment of the present invention provides a repeater including a receiver that receives instruction information for controlling a forwarding unit of the repeater, the instruction information including first information for indicating a time domain resource, the time domain resource being related to a subcarrier spacing.

[0011] Another aspect of an embodiment of the present invention provides an information indication method applied to a network device, the method including a step in which the network device transmits indication information for controlling a forwarding unit of the repeater to a mobile terminal of the repeater, the indication information including first information for indicating a time domain resource, the time domain resource being related to a subcarrier spacing.

[0012] Another aspect of an embodiment of the present invention provides a network device including a transmitter that transmits instruction information to a mobile terminal of a repeater for controlling a forwarding unit of the repeater, the instruction information including first information for indicating a time domain resource, the time domain resource being related to a subcarrier spacing.

[0013] Another aspect of the embodiment of the present invention provides a communication system including the repeater and / or the network device described above.

[0014] One of the advantageous effects of an embodiment of the present invention is that the network device controls the repeater so that the beam (corresponding time domain resource) when the repeater transmits matches the beam (corresponding time domain resource) when receiving the transmitted signal, or so that the time domain resource corresponding to the on state of the transmission unit matches the time domain resource for data transmission between the network device and the terminal device, thereby improving the effect of signal amplification / enhancement, saving the power consumption of the repeater, reducing interference to other devices in the network, and improving network throughput.

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

[0021] In embodiments of the present invention, the terms "first," "second," etc. are used in titles to distinguish between different elements, but do not represent the spatial arrangement or temporal order of these elements, and these elements are not limited to these terms. The term "and / or" includes any and all combinations of one or more of the terms listed in the associated list. The terms "comprise," "include," "have," etc. refer to the presence of listed features, elements, elements, or components, but do not exclude the presence or addition of one or more other features, elements, elements, or components.

[0022] In the embodiments of the present invention, the singular forms "one," "the," etc., include the plural and should be understood broadly as "one kind" or "one class," and are not limited to "one."

Furthermore, the term "described in" should be understood to mean "described at least in part," and the term "based on" should be understood to mean "based at least in part," unless the context clearly indicates otherwise.

[0023] In embodiments of the present invention, the terms "communication network" or "wireless communication network" may refer to a network conforming to any communication standard, such as, for example, Long Term Evolution (LTE), Long Term Evolution Advanced (LTE-A, LTE-Advanced), Wideband Code Division Multiple Access (WCDMA), High-Speed ​​Packet Access (HSPA), etc.

[0024] Additionally, communications between devices in a communications system may occur according to any stage of communications protocol, including, but not limited to, 1G (generation), 2G, 2.5G, 2.75G, 3G, 4G, 4.5G, and future 5G, New Radio (NR), etc., and / or other currently known or future developed communications protocols.

[0025] In an embodiment of the present invention, the term "network device" refers to a device in a communication system that allows a terminal device to access the communication system and provides a service to the terminal device, and may include, but is not limited to, a base station (BS), an access point (AP), a transmission reception point (TRP), a broadcast transmitter, a mobility management entity (MME), a gateway, a server, a radio network controller (RNC), a base station controller (BSC), etc.

[0026] Among them, the base station may include, but is not limited to, a Node B (NodeB or NB), an evolved Node B (eNodeB or eNB), a 5G base station (gNB), an IAB donor, etc., as well as a remote radio head (RRH), a remote radio unit (RRU), a relay, or a low-power node (e.g., femto, pico, etc.). The term "base station" may include some or all of these functions, and each base station may provide communication coverage for a particular geographic area. The term "cell" may refer to a base station and / or its coverage area, depending on the context in which the term is used.

[0027] In the embodiments of the present invention, the term "User Equipment" (UE) or "Terminal Equipment" (TE) refers to a device that accesses a communication network and receives network services via, for example, a network device. The terminal device may be fixed or mobile, and may also be referred to as a mobile station (MS), a terminal, a subscriber station (SS), an access terminal (AT), a station, etc.

[0028] Among them, the terminal device may include, but is not limited to, a mobile phone, a personal digital assistant (PDA), a wireless modulation / demodulation device, a wireless communication device, a handheld device, a machine-type communication device, a laptop computer, a cordless phone, a smartphone, a smart watch, a digital camera, etc.

[0029] For example, in a scenario such as the Internet of Things (IoT), the user equipment may be a monitoring or measuring device or apparatus, including, but not limited to, a Machine Type Communication (MTC) terminal, an in-vehicle communication terminal, a Device to Device (D2D) terminal, a Machine to Machine (M2M) terminal, etc.

[0030] To improve coverage, 3GPP Rel-17 study introduces an RF repeater to forward transmissions between a user equipment (UE) and a network device (base station). The RF repeater introduced in Rel-17 is transparent to the network device and the user equipment, i.e., the network device and the user equipment are unaware of the existence of the RF repeater.

[0031] 1 is a schematic diagram of an example of an application scenario of an embodiment of the present invention. As shown in FIG. 1, for convenience of explanation, one network device (for example, a gNB of a 5G base station) 101, one repeater 102, and one user equipment (UE) 103 are described as an example, but the present invention is not limited thereto.

[0032] 1, a terminal device 103 and a network device 101 establish a connection and communicate with each other. To improve communication quality, a channel / signal between the terminal device 103 and the network device 101 is transferred via a repeater 102. The interaction of the channel / signal between the network device 101, the terminal device 103, and the repeater 102 uses a beam-based receiving and transmitting method.

[0033] 1, the network device 101 may have a first cell / carrier, and the network device 101, the repeater 102, and the terminal device 103 can transmit / communicate in the first cell. However, the present invention is not limited thereto, and for example, the network device 101 may have another cell / carrier.

[0034] In an embodiment of the present invention, existing or future services may be performed between the network device and the terminal device, including, but not limited to, enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), highly reliable and low latency communications (URLLC), and vehicle-to-everything (V2X) communications.

[0035] Because conventional repeaters do not have the ability to communicate with network devices, they can help improve signal strength, but are not flexible enough to respond to complex environmental changes. Deploying conventional repeaters in a 5G network (especially in a high-frequency 5G network) may cause unnecessary interference to other network devices and / or terminal devices, and reduce the transmission efficiency (e.g., throughput) of the entire network. To make repeater forwarding more flexible to match the characteristics of the 5G network, network devices need to be able to support repeaters and configure repeater forwarding according to network conditions.

[0036] In 3GPP Rel-18, a network-controlled repeater (NCR) is proposed to forward signals between network devices and terminal devices to improve NR coverage. The NCR can directly communicate with the network devices via a control link to support the NCR forwarding operation.

[0037] 2 is a schematic diagram of an example of an NCR according to an embodiment of the present invention. As shown in FIG. 2, the NCR 202 is disposed between a network device 201 and a terminal device 203. The NCR 202 may include two modules / components: a repeater mobile terminal (NCR-MT) and a repeater forwarding unit (NCR-Fwd). The NCR-Fwd is also 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 transmitted and received between the network device and the terminal device. The NCR-MT and NCR-Fwd are functional entities that may be realized by the same or different hardware modules.

[0038] As shown in Fig. 2, the NCR of the embodiment of the present invention can have three links, namely, a control link (C-link), a backhaul link (BH link) for transmission, and an access link (AC link). Here, the C-link is used for communication between the NCR and the network device. The BH link is used by the repeater to receive signals to be transmitted from the network device or to transmit signals from the terminal device to the network device. The AC link is used by the repeater to transmit signals from the network device to the terminal device or to receive signals to be transmitted from the terminal device.

[0039] According to the findings of the inventors of the present invention, 5G systems are more complex than conventional 3G, 4G systems, etc., and need to support, for example, more types of services and terminal types, and be deployed in, for example, various frequency bands and scenarios. Compared with conventional RF repeaters, NCRs need to have beam-based functions.

[0040] In addition, the on / off of a conventional repeater is usually manually configured and cannot dynamically match the data transmission between the network device and the UE. Generally, data transmission between the network device and the UE is not always performed. If the repeater is on when there is no data transmission between the network device and the UE, unnecessary power consumption increases, interference occurs to other devices, and network throughput may decrease. Therefore, compared with a conventional RF repeater, an NCR needs to have a function for controlling the on / off of the transmission function.

[0041] However, according to the discovery of the inventors of the present invention, how a repeater indicates / determines the period (time domain resource) corresponding to the AC link beam and / or the period (time domain resource) corresponding to the on / off of the transmission unit, in particular, how to indicate / determine the subcarrier spacing for determining the time domain resource corresponding to the AC link beam and / or the subcarrier spacing for determining the time domain resource corresponding to the on / off of the transmission unit, is an issue that needs to be resolved as soon as possible.

[0042] The following describes various aspects of the embodiments of the present invention with reference to the drawings. These aspects are merely illustrative and do not limit the present invention.

[0043] In an embodiment of the present invention, a repeater can communicate with a network device. The repeater can receive a communication channel / signal transmitted by the network device and obtain information transmitted by the network device to the repeater by demodulating / decoding the channel / signal. This signal processing process is hereinafter referred to as "communication." The repeater can also forward a channel / signal transmitted between a network device and a terminal device. The repeater can amplify or process the channel / signal without demodulating / decoding it. This signal processing process is hereinafter referred to as "forwarding." "Communication" and "forwarding" are collectively referred to as "transmission." Furthermore, "transmitting or receiving (using a beam) in an AC link" can be equivalent to "transferring (using a beam) in an AC link," and "transmitting or receiving in a control link" can be equivalent to "communicating in a control link." The above terms are merely for convenience of explanation and do not limit the present invention. In some cases, the "forwarding unit" may be replaced with a "forwarding operation."

[0044] For convenience of explanation, a channel / signal directly communicating between a network device and a repeater, or between a third device (e.g., a terminal device) and a repeater may be referred to as a communication signal, and when transmitting a communication signal, the repeater needs to encode and / or modulate the communication signal, and when receiving a communication signal, the repeater needs to decode and / or demodulate the communication signal. Also, a channel / signal forwarded via a repeater may be referred to as a transport signal, and the repeater may perform signal processing such as amplification on the forwarded signal, but does not perform decoding and / or demodulation.

[0045] In an embodiment of the present invention, a repeater may be represented as a network-controlled repeater, forwarder, radio frequency repeater, radio frequency repeater, or as a repeater node, forwarder node, repeater node, or as a smart repeater, smart forwarder, smart repeater, smart repeater node, smart forwarder node, smart repeater node, etc., but the present invention is not limited thereto.

[0046] In the embodiments of the present invention, the network device may be a device of a serving cell of a terminal device, a device of a cell in which a repeater is located, a device of a serving cell of a repeater, or a parent node of a repeater. The present invention is not limited to the name of the repeater, and any device capable of realizing the above functions is included in the scope of the repeater according to the present invention.

[0047] In an embodiment of the present invention, a beam may be represented as a reference signal (RS), a transmission configuration indication (TCI), a spatial domain filter, etc., or may be represented as a beam index, a reference signal index, a transmission configuration indication index, a spatial domain filter index, etc. Examples of the reference signal include a channel state information reference signal (CSI-RS), a sounding reference signal (SRS), an RS for a repeater, an RS transmitted by a repeater, etc. The TCI may be represented as a TCI state. However, the embodiment of the present invention is not limited thereto.

[0048] The following will be explained with reference to examples.

[0049] Example 1 The embodiment of the present invention provides an information indication method and is explained from the repeater side.

[0050] 3 is a schematic diagram of an example of an information indication method according to an embodiment of the present invention. As shown in FIG. 3, the method may include the following steps:

[0051] Step 301: A mobile terminal of a repeater receives instruction information for controlling a forwarding unit of the repeater, the instruction information including first information for indicating a time domain resource, the time domain resource being related to a subcarrier spacing.

[0052] Note that the above-mentioned FIG. 3 merely exemplifies an embodiment of the present invention and is not limited thereto. For example, the execution order of each step may be adjusted as appropriate, and some other steps may be added or some steps may be deleted. Those skilled in the art may appropriately modify the above content and are not limited to the description of the above-mentioned FIG. 3.

[0053] In some embodiments, the instruction information may be first instruction information for controlling the access link beam of the repeater, second instruction information for controlling the on and / or off of the forwarding unit of the repeater, or third instruction information for controlling the back link beam of the repeater, as will be described in detail below.

[0054] (1) Related to the first instruction information In some embodiments, the AC link beam may be referred to as the terminal device side beam, and refers to the receive beam / transmit beam employed (used) by the repeater on the AC link, where the transmit beam transfers signals from the network device to the terminal device, and the receive beam transfers signals from the terminal device to the network device, where the (antenna) beam refers to, for example, the main lobe of the radiation pattern of an antenna array.

[0055] In some embodiments, a repeater may support multiple beams (or antenna beams) with different directions and / or widths, and a correlation relationship may exist between the beams. For example, a correlation relationship between a first beam and a second beam may include the following: the first beam and the second beam have the same beam center direction; and / or the first beam and the second beam have the same beam peak direction; and / or the first beam and the second beam are quasi-collocated (e.g., QCL Type D); and / or the first beam is within the second beam range or the second beam is within the first beam range; and / or the beamwidth of the first beam is within the beamwidth range of the second beam; and / or the beamwidth of the second beam is within the beamwidth range of the first beam. Here, the beam center direction may refer to, for example, the geometric center of the half-power contour of the beam, and the beam peak direction may refer to, for example, the direction in which the maximum EIRP of the beam is located.

[0056] 4 is a schematic diagram of an example of an AC link beam of an NCR according to an embodiment of the present invention. As shown in FIG. 4, the repeater can support multiple beams of different directions and / or widths, beam#1, beam#2, beam#3, beam#4, and beam#5, where beam#1 and beam#5 have an associated relationship.

[0057] In some embodiments, the repeater explicitly and / or implicitly reports to the terminal device the number of beams and / or the association between the beams supported by its AC link.

[0058] For example, the repeater directly reports the number of beams supported by the AC link, eg, one of 1 / 2 / 4 / 8.

[0059] Also, for example, the repeater reports the number of beams and the association between the beams, for example, the number of first beams is one of 1 / 2 / 4 / 8, and the number of second beams is one of 1 / 2 / 4 / 8 (the value range is the same as or different from the first beams). If there are M second beams, each first beam is associated with M second beams.

[0060] As another example, the repeater may report an association between the number of beams and the beam, e.g., 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, then each first beam is associated with, e.g., M / N second beams.

[0061] As another example, the repeater reports the number of beams and the association between the beams, e.g., the first beam is one of 1 / 2 / 4 / 8, and the number of second beams associated with different first beams is different, e.g., different first beams correspond to 1 / 2 / 4 / 8 second beams, respectively.

[0062] As another example, the repeater reports the number of beams and the association between the beams, reporting the total number of beams and the number of primary beams N, and further indirectly reporting the number of secondary beams M and the secondary beams associated with each primary beam.

[0063] Here, the relationship between the second beam and the first beam is as described above, and the first beam is referred to as, for example, the source beam of the second beam or the QCL source beam.

[0064] In some embodiments, to control the access link beam of the repeater, the network device transmits to the repeater first instruction information for controlling the access link beam of the repeater, the first instruction information including access link beam instruction information, and / or identification information, and / or packet information, and / or priority information, and / or first information indicating a first time domain resource corresponding to the access link beam.

[0065] 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, where the first PHY signaling may be a first DCI, such as a unicast DCI or a group common DCI, and the format of the first DCI may be a conventional DCI format (e.g., 1_1, 2_0) or a newly introduced DCI format.

[0066] In some embodiments, the first instruction information may indicate which beam the repeater should use (to transmit) during a certain period of time. In other words, the first instruction information includes at least access link beam instruction information for indicating an AC link beam, and the access link beam instruction information may be a beam index, and the indicated beam is one of the first beams, and the indicated range does not include the second beam, but embodiments of the present invention are not limited thereto, and the indicated beam may include the second beam.

[0067] In some embodiments, the first instruction information may further include first information indicating a time domain resource (first time domain resource) corresponding to the beam it indicates, where the time domain resource (first time domain resource) corresponding to the beam means a period during which transmission is performed using the beam.

[0068] In some embodiments, the beam indicated by the first instruction may be periodic, semi-persistent (which may also be referred to as semi-static), or aperiodic (which may also be referred to as dynamic). In other words, the time domain resource (first time domain resource) corresponding to the beam indicated by the first instruction may be periodic, semi-persistent, or aperiodic.

[0069] I. The first time domain resource is periodic or semi-persistent In some embodiments, the first indication information is carried by a first RRC signaling, the first RRC signaling includes one or more pieces of first configuration information, and the first configuration information includes all of the information in the first indication information.

[0070] In some embodiments, the first indication information is carried by first MAC signaling, and the first MAC signaling includes one or more first configuration information, and the first configuration information includes all of the information in the first indication information.

[0071] In some embodiments, the first indication information is carried by first RRC signaling plus first MAC signaling and / or first PHY signaling, the first RRC signaling including one or more pieces of first configuration information, the first configuration information including all or part of the information of the first indication information, and the first MAC signaling and / or the first PHY signaling further including identification information indicating one or more first configurations of the one or more pieces of first configuration information and / or part of the information of the first indication information.

[0073] Here, the first information includes information indicating a first time domain resource within one 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.

[0074] Here, a portion of the first information included in the first configuration information includes period information, and a portion of the first information included in the first MAC signaling and / or the first PHY signaling includes information indicating a first time domain resource within one period.

[0075] Here, the information indicating the first time domain resource within the first period includes at least one first time length information and / or at least one first offset information, the first time length includes a millisecond-level time length, a slot-level time length, and / or a symbol-level time length, and the first offset includes a millisecond-level offset, a slot-level offset, and / or a symbol-level offset.

[0076] The following will be explained with reference to an example.

[0077] In some embodiments, the first indication information may be carried only by the first RRC signaling.

[0078] The first RRC signaling may include one or more pieces of first configuration information, and the first configuration information may include all information in the first indication information. That is, the repeater may receive one or more pieces of first indication information carried by the first RRC signaling. The first information included in one piece of first indication information may include information indicating first time domain resources within one period and / or period information. Here, the information indicating the first time domain resources within one period may include information on at least one first duration and / or at least one first offset of the first time domain resources. For example, the first information may include one piece of period information, one or more pieces of first offset information, and one or more pieces of first duration information. Here, 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 time length information, and different beams correspond to the same or different first offset information and / or different beams correspond to the same or different first time length information. The above-mentioned first offset refers to an offset between a time domain resource start position of a corresponding beam within one period and a reference position, and the reference position may be, for example, a system frame start position after receiving a first RRC signaling or an end position of a time domain resource corresponding to another beam, but the embodiment of the present invention is not limited thereto.

[0079] In some embodiments, the period and / or the first time length and / or the first offset includes at least one time unit, and the first information indicates the period and / or the first time length and / or the first offset by the number of the time units. The at least one time unit may be continuous across the time domain or may not be continuous across the time domain. The time unit may be a subframe, a slot, a symbol, a mini-slot, a millisecond, etc. That is, the period may include a millisecond-level period and / or a slot-level period and / or a symbol-level period, the first time length may include a millisecond-level period and / or a slot-level period and / or a symbol-level period, the first offset may include a millisecond-level offset and / or a slot-level offset and / or a symbol-level offset, and the first time domain resource (length of the time unit) is related to the subcarrier spacing. A method for determining the first time domain resource based on the subcarrier spacing will be described below.

[0080] 5A to 5G are schematic diagrams of first instruction information according to an embodiment of the present invention. As shown in FIG. 5A, the indicated beam is Beam #1, which corresponds to one first offset and one first time length. As shown in FIG. 5B, the indicated beams are Beam #1 and Beam #2, which correspond to one first offset and one first time length. Specifically, the first time length of each beam may be determined according to implementation. As shown in FIG. 5C, the indicated beams are Beam #1 and Beam #2, which correspond to one first offset and two first time lengths. The two first time lengths correspond to Beam #1 and Beam #2, respectively. As shown in FIG. 5D, the indicated beams are Beam #1 and Beam #2, and two first offsets correspond to Beam #1 and Beam #2. The reference positions of the first offsets are the same, and the first time lengths of the two beams are the same. As shown in Figure 5E, the commanded beams are Beam #1 and Beam #2, and correspond to two first offsets and two first time lengths, the two first offsets corresponding to Beam #1 and Beam #2, respectively, and the two first time lengths corresponding to Beam #1 and Beam #2, respectively. As shown in Figure 5F, the commanded beams are Beam #1 and Beam #2, and correspond to two first offsets and one first time length, the two first offsets corresponding to Beam #1 and Beam #2, respectively, and Beam #1 and Beam #2 correspond to the same first time length. As shown in Figure 5G, the beams to be instructed are Beam #1 and Beam #2, which correspond to two first offsets and two first time lengths, the two first offsets correspond to Beam #1 and Beam #2, respectively, and the two first time lengths correspond to Beam #1 and Beam #2, respectively, and unlike Figure 5E, the reference position of the first offset 2 is different.

[0081] 5A to 5G have been described above using Beam#1 and Beam#2 as examples, but the present invention is not limited to this and may show other numbers of beams. Also, although the corresponding time domain resources in one period of the same beam are continuous, this is not limited thereto and they may be discontinuous (for example, one beam may correspond to multiple first offsets and / or first time length information and constitute discontinuous time domain resources).

[0082] The one or more first indication information are included in one information element / field (IE / field) of the first RRC signaling, and this IE / field may be repeater-specific, i.e., this IE / field applies only to the repeater and is used to control the forwarding unit of the repeater. The IE / field may further include the second indication information and / or the third indication information, for example, or the first indication information may include the second indication information and / or the third indication information, or the first indication information may function as the second indication information. Details will be described later.

[0083] In some embodiments, the first indication information is carried by the first RRC signaling and the first MAC signaling and / or the first PHY signaling, where the embodiments of the first RRC signaling are as described above, and the first MAC signaling and / or the first PHY signaling are used to activate and / or deactivate one or more first configurations of the one or more pieces of first configuration information. For example, the above-mentioned first MAC signaling and / or the PHY signaling further include identification information indicating one or more first configurations of the one or more pieces of first configuration information.

[0084] For example, the first RRC signaling includes multiple pieces of first configuration information, and the identification information in the first MAC signaling and / or the first PHY signaling is a first configuration corresponding to one or more activated first indication information, and the repeater performs transmission using a corresponding beam in a corresponding time domain resource according to the activated first configuration. For example, the first RRC signaling includes eight pieces of first configuration information, the first MAC signaling is 00000010, and the seventh piece of first configuration information is activated, but other details are omitted here. Figure 6 is a schematic diagram of first indication information according to an embodiment of the present invention. 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 by the seventh first configuration information are Beam #1 and Beam #2, and the first information includes two first offsets and two first time lengths, corresponding to Beam #1 and Beam #2, respectively.

[0085] In some embodiments, when activated using the first PHY signaling, it may be activated directly based on the configuration of the first RRC signaling, or it may be activated based on further configuration of the first MAC signaling (i.e., activated and / or deactivated by the MAC CE and DCI).

[0086] In some embodiments, the first indication information is carried by first MAC signaling and first PHY signaling, the first MAC signaling including one or more pieces of first configuration information, an embodiment of the first configuration information being similar to the first RRC signaling, and the first PHY signaling being used to activate and / or deactivate one or more first configurations of the one or more pieces of first configuration information. For example, the first PHY signaling further includes identification information indicating one or more first configurations of the one or more pieces of first configuration information. The repeater performs transmission using each beam in each time domain resource according to the activated configuration.

[0087] In some embodiments, the first indication information is carried by the first RRC signaling, and the first MAC signaling and / or the first PHY signaling. Unlike the above embodiments, each piece of information (the period and / or at least one first time length and / or at least one first offset) of the first information is not all included in one signaling, but is carried by the first RRC signaling, and the first MAC signaling and / or the first PHY signaling, respectively. For example, some of the first information included in the first configuration information includes period information, and some of the first information included in the first MAC signaling and / or the first PHY signaling includes information indicating a first time domain resource within one period (at least one piece of first time length information and / or at least one piece of first offset information). Note that the embodiments of the present invention are not limited thereto. For example, a portion of the first information included in the first configuration information includes periodicity information and at least one piece of first time length information, and the first MAC signaling and / or the first PHY signaling includes at least one piece of first offset information. Alternatively, for example, a portion of the first information included in the first configuration information includes periodicity information, at least one piece of first time length information, and at least one piece of first offset information, and the first MAC signaling and / or the first PHY signaling includes one or more pieces of first time length information and one or more pieces of first offset information.

[0088] In the above example, the first PHY signaling includes one or more first information fields, and at least one first information field is used to indicate a 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. For how the first information field indicates (the first time length and / or the first offset) of the first time domain resource, reference may be made to the exemplary description in "II" below.

[0089] Note that the time units of the first time length information carried by the first RRC signaling and the first MAC signaling and / or the first PHY signaling may be the same or different. For example, the time units of the first time length information corresponding to different beams may be the same or different, or the first time length information carried by the first RRC signaling corresponding to the same beam may be the same or different from the first time unit carried by the first PHY signaling. Other examples will not be described here. The time units of the first offset information carried by the first RRC signaling and the first MAC signaling and / or the first PHY signaling may be the same or different. For example, the time units of the first offset information corresponding to different beams may be the same or different, or the time units of the first offset information carried by the first RRC signaling corresponding to the same beam may be the same or different from the first PHY signaling. Other examples will not be described here.

[0090] II. The first time domain resource is aperiodic In some embodiments, the first indication information is carried by first PHY signaling, the first PHY signaling including one or more first information fields, at least one of which is used to indicate a first time domain resource. The first information field includes a time domain resource allocation information field. TDRA tables corresponding to different time domain resource allocation information fields may be the same or different, and the one or more first information fields are used to indicate at least one second time length information and / or at least one second offset information. For example, the first PHY signaling may be the above-mentioned first DCI, and the repeater receives the first DCI including one or more first indication information, where the first information indicating the first time domain resource corresponding to the beam is indicated by the first information field included in the first DCI. However, embodiments of the present invention are not limited thereto.

[0091] In some embodiments, a time domain resource allocation (TDRA) table (or simply referred to as a TDRA table) includes at least one row. Hereinafter, for convenience of explanation, one row is referred to as one TDRA configuration. That is, the TDRA table includes at least one TDRA configuration. One TDRA configuration includes at least one time domain resource configuration, which includes at least a symbol position within a slot (start symbol + length) configuration. One TDRA configuration may also include at least one slot offset K0 configuration, which may or may not be included in the time domain resource configuration. One TDRA configuration may further include other information (e.g., mapping type), which may or may not be included in the time domain resource configuration. The embodiments of the present invention are not limited thereto. Here, the symbol position configuration within a slot may, for example, include a start and length indicator SLIV, which corresponds to a valid combination of a starting symbol (S) and a length (L), or may, for example, correspond to a starting symbol configuration and a length configuration, which is a valid combination.

[0092] For example, the first DCI includes one or more TDRA information fields, where one TDRA information field indicates a row of a TDRA configuration, and the TDRA tables corresponding to different time domain resource allocation information fields are the same or different.

[0093] For example, the first DCI includes one TDRA information field, and the TDRA information field (corresponding to the first information in the first indication information) is used to indicate a first time domain resource corresponding to an access link beam. Assuming that the first DCI may also be used to schedule the PDSCH / PUSCH of the NCR-MT, if the first DCI is used to schedule the PDSCH / PUSCH of the NCR-MT, the TDRA field is used to indicate a fourth time domain resource corresponding to the PDSCH / PUSCH. If the DCI is not used to schedule the PDSCH / PUSCH of the NCR-MT but is used to control the access link beam of the transmission unit, the TDRA field is used to indicate the first time domain resource corresponding to the beam. In either case, the TDRA tables corresponding to the TDRA information field may be the same or different. In other words, the TDRA tables applied to the first time domain resource and the fourth time domain resource may be the same or different.

[0094] As another example, the first DCI includes two TDRA fields, one for indicating a first time domain resource corresponding to an access link beam and the other for indicating a fourth time domain resource corresponding to a PDSCH / PUSCH of an NCR-MT, so that the first DCI can support both scheduling the PDSCH / PUSCH of an NCR-MT and controlling the forwarding operation (indicating an access link beam) of the forwarding unit.

[0095] As another example, the first DCI includes multiple TDRA fields, at least two of which are used to indicate first time domain resources corresponding to the same or different beams indicated by the first DCI.

[0096] In the above example, the repeater can support one or more of the above methods. The method may further include the repeater reporting capability information to the network device. The capability information is used to inform the network device of the information indication method supported by the repeater. The network device can control its beam in the method supported by the repeater according to the capability information.

[0097] In the above example, one TDRA information field (the bit value of the information field is the configured row number) is used to indicate one TDRA configuration similar to the above first configuration information. This one TDRA configuration (first information) includes at least one second time length information and / or at least one second offset information of the first time domain resource. The second offset may correspond to the above K0 configuration, and the second offset refers to the offset between the start position of the first time domain resource and the end position of the PDCCH carrying the first DCI. However, the embodiment of the present invention is not limited thereto. For example, the second offset may be the offset between the start position of the first time domain resource corresponding to one beam and the end position of the first time domain resource corresponding to the immediately adjacent beam, and the second offset may correspond to the above SLIV configuration.

[0098] In some embodiments, a TDRA configuration may include at least one second time length information and / or at least one second offset information of a first time domain resource. The second time length and / or second offset include at least one time unit, and the first information indicates the second time length and / or second offset by indicating the number of the time units, and the at least one time unit may be contiguous across the time domain or may not be contiguous across the time domain. The time unit may be, for example, a subframe, slot, symbol, mini-slot, millisecond, etc. In other words, the second time length may include a millisecond-level time length, a slot-level time length, and / or a symbol-level time length, and the second offset may include a millisecond-level offset, a slot-level offset, and / or a symbol-level offset. The first time domain resource (length of the time unit) is related to a subcarrier spacing, and the time units of the at least one second time length may be the same or different, and the time units of the at least one second offset information may be the same or different. Here, examples are omitted. A method for determining the first time domain resource according to the subcarrier spacing will be described later. Explanations of contents that overlap with "I" will be omitted.

[0099] 8A to 8G are schematic diagrams of first instruction information according to an embodiment of the present invention. As shown in FIG. 8A, the indicated beam is Beam #1, corresponding to one second offset and one second time length. As shown in FIG. 8B, the indicated beams are Beam #1 and Beam #2, corresponding to one second offset and one second time length. Specifically, the second time length of each beam may be determined according to implementation. As shown in FIG. 8C, the indicated beams are Beam #1 and Beam #2, corresponding to one second offset and two second time lengths, the two second time lengths corresponding to Beam #1 and Beam #2, respectively. As shown in FIG. 8D, the indicated beams are Beam #1 and Beam #2, corresponding to two second offsets and one second time length, the two second offsets corresponding to Beam #1 and Beam #1, respectively. The reference positions of the second offsets are the same, and the second time lengths of the two beams are the same. As shown in FIG. 8E, the commanded beams are Beam#1 and Beam#2, and correspond to two second offsets and two second time lengths, where the two second offsets correspond to Beam#1 and Beam#2, respectively, and the two second time lengths correspond to Beam#1 and Beam#2, respectively. As shown in FIG. 8F, the commanded beams are Beam#1 and Beam#2, and correspond to two second offsets and one second time length, where the two second offsets correspond to Beam#1 and Beam#2, respectively, and Beam#1 and Beam#2 correspond to the same second time length. As shown in FIG. 8G, the displayed beams are Beam#1 and Beam#2, and correspond to two second offsets and two second time lengths, where the two second offsets correspond to Beam#1 and Beam#2, respectively, and the two second time lengths correspond to Beam#1 and Beam#2, respectively. 8F and 8G differ from FIG. 8E in that the reference position of the second offset 2 is different.

[0100] The beams in Figures 8A to 8G above are Beam #1 and Beam #2 as examples, but are not limited to this and may show other numbers of beams, and the first time domain resource is continuous but is not limited to this and may be discontinuous (for example, one beam may correspond to multiple second offsets and / or second time length information and constitute discontinuous time domain resources).

[0101] In some embodiments, the first time domain resources corresponding to different beams indicated by the first instruction information may overlap (partially or completely). For example, the received first RRC signaling includes one or more first configuration information (first instruction information), and the first time domain resources corresponding to two or more beams among some of the beams indicated by the different first instruction information may overlap, but the repeater may not be capable of transmitting using two or more beams simultaneously. Therefore, the method further includes the repeater determining, based on an instruction from the network device and / or a predefined method, a beam to which the overlapping first time domain resources should be applied.

[0102] In some embodiments, the repeater may determine the beam to which the first time domain resource of the overlapping portion should be applied based on instructions from the network device.

[0103] For example, the first instruction information may include priority information, identification information, and / or packet information. The repeater performs transmission using a beam indicated by the first instruction information with the highest corresponding priority and / or the lowest corresponding identifier. For example, the identification information may be determined from the identification information and / or packet information. For example, the second beam associated with the first beam is classified into the same group, and the packet information may be a group index, and the identification information may be the identification of the second beam within the group, etc., which will not be described here.

[0104] The above is merely an example, and the priority information and / or identification information and / or packet information may not be included in the first instruction information, but may be included in the fourth instruction information separately transmitted by the network device, and the embodiment of the present invention is not limited thereto.

[0105] In some embodiments, the repeater may determine which beam the first time domain resource of the overlapping portion should adopt according to a predefined rule.

[0106] For example, the two or more beams may include a first beam that is employed (the remaining beam may or may not be a second beam related to the first beam). Also, for example, the beam with the smallest index among the two or more beams is adopted.

[0107] Furthermore, for example, the two or more beams include a plurality of first beams, and the beam with the smallest index among the plurality of first beams is adopted.

[0108] Also, for example, multiple first instruction information are included in the same list (multiple first configuration information are included in the same configuration list), and the repeater determines which beam to adopt based on the position / order of the first instruction information in the list. For example, if one of the two or more beams is designated by the first first instruction information in the list, the one beam designated by this first first instruction information is adopted, if one of the two or more beams is designated by the second first instruction information in the list, and if there is no beam designated by the first first instruction information in the list, the one beam designated by this second first instruction information is adopted, and so on.

[0109] (d) Related to the second instruction information In some embodiments, to enable the repeater to have a function of controlling the on / off of the forwarding function, the repeater may receive second instruction information for controlling the on and / or off state of the forwarding unit of the repeater, which may indicate whether the forwarding unit of the repeater is in the on state or the off state during a certain period (second time domain resource).

[0110] In some embodiments, this first indication may be used as a second indication and may be used to implicitly indicate the on and / or off state of the forwarder.

[0111] In some embodiments, this second indication information may include the first indication information and / or information indicating the uplink / downlink direction, and may implicitly indicate an on state and / or an off state of the forwarding unit using the first indication information and / or information indicating the uplink / downlink direction.

[0112] For example, in the first time domain resource corresponding to the beam indicated by this first instruction information, the forwarding unit is in an on state, and in the other time domain resources, the forwarding unit is in an off state (by default), and / or in the flexible time domain resource indicated by the information indicating the uplink / downlink direction, the forwarding unit is in an off state (by default), and / or in the time domain resource among the first time domain resources corresponding to the beam indicated by the first instruction information, for which the information indicating the uplink / downlink direction is indicated as a flexible time domain resource, the forwarding unit is in an off state (by default).

[0113] Here, when the first indication information is used to implicitly indicate the on state and / or off state of the forwarder, the first time domain resource indicated by the first indication information may be referred to as a second time domain resource corresponding to the forwarder on (and / or off) state, and the first subcarrier spacing and / or second subcarrier spacing for the first time domain resource may be referred to as a third subcarrier spacing and / or a fourth subcarrier spacing corresponding to the second time domain resource. Details of the third subcarrier spacing and / or the fourth subcarrier spacing will be described later. In some embodiments, the second indication information includes third information indicating the on state and / or the off state and / or first information indicating the second time domain resource corresponding to the on state and / or the off state.

[0114] For example, the second instruction information may include only the third information indicating the ON state and / or the OFF state, and the second time domain resource may be determined according to a predetermined rule or the start position of the second time domain resource may be determined based on the third information, and the transmitting unit may be turned ON and / or OFF from the start position until new second instruction information is received, and perform corresponding operations according to the new second instruction information.

[0115] As another example, the second instruction information may include only the first information for indicating second time domain resources corresponding to the ON state and / or the OFF state. For example, the second instruction information may be used only to indicate second time domain resources corresponding to the ON state, or only to indicate second time domain resources corresponding to the OFF state. In this way, the ON state and / or the OFF state can be determined based on the first information without explicitly including the third information in the second instruction information.

[0116] In some embodiments, the second indication information includes the above-mentioned first indication information and the above-mentioned third information (optionally, may include information indicating the uplink / downlink direction).

[0117] For example, the third information is used to indicate only the off state, and in the first time domain resource (second time domain resource) that corresponds to the beam indicated by the above-mentioned first instruction information and for which the off state is not indicated by the third information, the transfer unit is in the on state, and in the other time domain resources, the transfer unit is in the default off state.

[0118] Also, for example, the third information is used to indicate only the off state, and corresponds to the beam indicated by the above-mentioned first instruction information, and in the first time domain resource (second time domain resource) (where the off state is not indicated by the third information and / or where it is indicated to be flexible by the information indicating the uplink / downlink direction), the transfer unit is in the on state, and in the other time domain resources, it is in the default off state.

[0119] In some embodiments, the second indication information is carried by at least one of second RRC signaling, second MAC signaling, or second PHY signaling. Here, the second PHY signaling may be a second DCI, such as a unicast DCI or a group common DCI. Meanwhile, the format of the second DCI may be a conventional 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, and the first PHY signaling and the second PHY signaling may be the same or different PHY signaling, but embodiments of the present invention are not limited thereto.

[0120] In some embodiments, the second time domain resource indicated by the second indication information (indicated by the first information) is periodic, semi-persistent (the former two are also referred to as semi-static), or aperiodic (dynamic), i.e., the time domain resource (second time domain resource) corresponding to the on and / or off state indicated by the second indication information is periodic, semi-persistent, or aperiodic.

[0121] I. The second time domain resource is periodic or semi-persistent In some embodiments, the second indication information is carried by second RRC signaling, the second RRC signaling includes one or more pieces of second configuration information, and the second configuration information includes all of the information in the second indication information.

[0122] In some embodiments, the second indication information is carried by second MAC signaling, the second MAC signaling includes one or more pieces of second configuration information, and the second configuration information includes all of the information in the second indication information.

[0123] In some embodiments, the second indication information is carried by second RRC signaling plus second MAC signaling and / or second PHY signaling, the second RRC signaling includes one or more pieces of second configuration information, the second configuration information includes all or part of the information of the second indication information, and the second MAC signaling and / or the second PHY signaling further include identification information for indicating one or more second configurations of the plurality of second indication information and / or part of the information of the second indication information.

[0124] In some embodiments, the second instruction information is carried by second MAC signaling + second PHY signaling, the second MAC signaling includes one or more pieces of second configuration information, the second configuration information includes all or part of the information of the second instruction information, and the second PHY signaling further includes identification information indicating one or more second configurations of the multiple pieces of second configuration information and / or part of the information of the second instruction information.

[0125] Here, the first information includes information indicating second time domain resources within one period and / or period information, the second configuration information includes all or part of the first information indicating the second time domain resources, and the second MAC signaling and / or the second PHY signaling includes part of the first information.

[0126] Here, a portion of the first information included in the second configuration information includes period information, and a portion of the first information included in the second MAC signaling and / or the second PHY signaling includes information indicating a second time domain resource within one period.

[0127] Here, the information indicating the second time domain resource within one period includes at least one piece of third time length information and / or at least one piece of third offset information, where the third time length includes a millisecond-level time length, a slot-level time length, and / or a symbol-level time length, and the third offset includes a millisecond-level offset, a slot-level offset, and / or a symbol-level offset.

[0128] The following will be explained with reference to an example.

[0129] In some embodiments, the second indication information may be carried by a second RRC signaling.

[0130] The second RRC signaling may include one or more pieces of second configuration information, and the second configuration information may include all information in the second indication information. That is, the repeater may receive one or more pieces of second indication information carried by the second RRC signaling. The first information included in the second indication information may include information indicating second time domain resources within one period and / or period information. Here, the information indicating the second time domain resources within one period includes at least one piece of third duration information and / or at least one piece of third offset information of the second time domain resources. For example, the first information may include one piece of period information, one or more pieces of third offset information, and one or more pieces of third duration information. Here, the ON state and / or the OFF state correspond to one or more pieces of third offset information and / or one or more pieces of third time length information, and / or the ON state and / or the OFF state correspond to the same or different third offset information, and / or the ON state and / or the OFF state correspond to the same or different third time length information. The above-mentioned third offset refers to an offset between a start position of a time domain resource corresponding to the ON state and / or the OFF state within one period and a reference position, and the reference position may be, for example, a start position of a system frame after receiving the second RRC signaling or an end position of a time domain resource corresponding to another ON state and / or the OFF state, but the embodiment of the present invention is not limited thereto.

[0131] In some embodiments, the period and / or the third time length and / or the third offset includes at least one time unit, and the first information indicates the number of time units to indicate the period and / or the third time length and / or the third offset. The at least one time unit may be contiguous across the time domain or may not be contiguous across the time domain. The time unit may be, for example, a subframe, a slot, a symbol, a mini-slot, a millisecond, etc. That is, the period may include a millisecond-level period and / or a slot-level period and / or a symbol-level period, the third time length may include a millisecond-level time length and / or a slot-level time length and / or a symbol-level time length, the third offset may include a millisecond-level offset and / or a slot-level offset and / or a symbol-level offset, and the second time domain resource (length of the time unit) is related to the subcarrier spacing. A method for determining the second time domain resource based on the subcarrier spacing will be described below.

[0132] 7A to 7G are schematic diagrams of first indication information according to an embodiment of the present invention. As shown in FIG. 7A, the indicated second time domain resource is the OFF state and corresponds to one third offset and one third duration. As shown in FIG. 7B, the second time domain resource corresponding to the ON state and the second time domain resource corresponding to the OFF state are respectively shown, corresponding to one third offset and one third duration, where the third duration of each state may be determined according to implementation. As shown in FIG. 7C, the second time domain resource corresponding to the ON state and the second time domain resource corresponding to the OFF state are respectively shown, corresponding to one third offset and two third durations, where the two third durations correspond to the OFF state and the ON state, respectively. As shown in FIG. 7D, the second time domain resource corresponding to the ON state and the second time domain resource corresponding to the OFF state correspond to two third offsets and one third time length, where the two third offsets correspond to the OFF state and the ON state, respectively, and the reference positions of the third offsets are the same, and the third time lengths for the OFF state and the ON state are the same. As shown in FIG. 7E, the second time domain resource corresponding to the ON state and the second time domain resource corresponding to the OFF state correspond to two third offsets and two third time lengths, where the two third offsets correspond to the OFF state and the ON state, respectively, and the two third time lengths correspond to the OFF state and the ON state, respectively. As shown in FIG. 7F, the second time domain resource corresponding to the ON state and the second time domain resource corresponding to the OFF state correspond to two third offsets and one third time length, where 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 time length. 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 shown, and two third offsets and two third durations are shown, where 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. Unlike Figure 7E, the reference position of the third offset 2 is different.

[0133] As shown in Figures 7A to 7G, the second time domain resources corresponding to one period are continuous, but this is not limited to this and may be discontinuous (for example, one on state and / or off state may correspond to multiple third offsets and / or third time length information, and may constitute discontinuous time domain resources).

[0134] The one or more second indication information pieces are included in one information element / field (IE / field) of the second RRC signaling, and this IE / field may be repeater-specific, i.e., this IE / field is only applicable to the repeater and is used to control the forwarding unit of the repeater. The above IE / field may further include, for example, the above first indication information piece and / or third indication information piece, and this information element / field may be the same as or different from the (first) information element / field, and the embodiment of the present invention is not limited thereto.

[0135] In some embodiments, the second indication information is carried by second RRC signaling and second MAC signaling and / or second PHY signaling, where the embodiments of the second RRC signaling are as described above, and the second MAC signaling and / or second PHY signaling are used to activate and / or deactivate one or more second configurations of the plurality of second configuration information. For example, the second MAC signaling and / or second PHY signaling further include identification information indicating one or more second configurations of the plurality of second configuration information.

[0136] For example, the second RRC signaling may include multiple pieces of second configuration information, and the identification information in the second MAC signaling and / or the second PHY signaling may be second configurations corresponding to one or more activated second indications. The repeater may turn on and / or off the transmission unit according to the time domain resources corresponding to the activated second configurations. For example, if the second RRC signaling includes eight pieces of second configuration information and the second MAC signaling is 00000010, the seventh piece of second configuration information is activated. The description thereof is omitted here. FIG. 9 is a schematic diagram of second indication information according to an embodiment of the present invention. As shown in FIG. 9, the second indication information is carried by the second RRC signaling and the second MAC signaling, and the seventh piece of second configuration information is activated, thereby turning on and / or off the transmission unit according to the corresponding time domain resources in the seventh piece of second configuration information. A seventh second configuration includes two third offsets and two third time lengths corresponding to the on and off states, respectively.

[0137] In some embodiments, when activated using the second PHY signaling, it may be activated directly based on the configuration of the second RRC signaling, or it may be activated based on further configuration of the second MAC signaling (i.e., activated and / or deactivated by the MAC CE and DCI).

[0138] 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 pieces of second configuration information, a specific embodiment of the second configuration information is similar to the second RRC signaling, and the second PHY signaling is used to activate and / or deactivate one or more second configurations of the plurality of pieces of second configuration information. The second PHY signaling further includes identification information indicating one or more second configurations of the plurality of pieces of second configuration information. The repeater turns on and / or turns off a forwarding unit according to the activated configuration.

[0139] In some embodiments, the second indication information is carried by the second RRC signaling, and the second MAC signaling and / or the second PHY signaling. Unlike the above embodiments, each piece of information (the period and / or at least one third time length and / or at least one third offset) of the first information is not all included in one signaling, but is carried by the second RRC signaling, and the second MAC signaling and / or the second PHY signaling, respectively. For example, a portion of the first information included in the second configuration information includes period information, and a portion of the first information included in the second MAC signaling and / or the second PHY signaling includes information indicating a second time domain resource within one period (at least one piece of third time length information and / or at least one piece of third offset information). Note that the embodiments of the present invention are not limited thereto. For example, a portion of the first information included in the second configuration information includes periodicity information and at least one piece of second time length information, and the second MAC signaling and / or the second PHY signaling includes at least one piece of third offset information. Alternatively, for example, a portion of the first information included in the second configuration information includes periodicity information, at least one piece of third time length information, and at least one piece of third offset information, and the second MAC signaling and / or the second PHY signaling includes one or more pieces of third time length information and one or more pieces of third offset information. Here, a description thereof will be omitted.

[0140] In the above example, the second PHY signaling includes one or more second information fields, and at least one second information field indicates a 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. For how the second information field indicates the second time domain resource (the third time length and / or the third offset), refer to the exemplary description in "II" below.

[0141] Note that the time units of the third time length information carried by the second RRC signaling and the second MAC signaling and / or the second PHY signaling may be the same or different. For example, the time units of the third time length information corresponding to different beams may be the same or different, or the third time length information carried by the second RRC signaling corresponding to the same beam may be the same or different from the third time unit carried by the second PHY signaling, and a description thereof will be omitted here. The time units of the third offset information carried by the second RRC signaling and the second MAC signaling and / or the second PHY signaling may be the same or different. For example, the time units of the third offset information corresponding to different beams may be the same or different, or the time units of the third offset information carried by the second RRC signaling corresponding to the same beam may be the same or different from the third offset information carried by the second PHY signaling, and a description thereof will be omitted here.

[0142] II. The second time domain resource is aperiodic In some embodiments, the second indication information is carried by second PHY signaling, the second PHY signaling including one or more second information fields, at least one of which indicates a second time domain resource. The second information field includes a time domain resource allocation information field. TDRA tables corresponding to different time domain resource allocation information fields may be the same or different, and the one or more second information fields may be used to indicate at least one piece of fourth time length information and / or at least one piece of fourth offset information. For example, the second PHY signaling may be the second DCI (the second DCI may be the first DCI or a DCI different from the first DCI). The repeater receives the second DCI, and the second DCI includes one or more pieces of second indication information, where the first information used to indicate 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 invention are not limited thereto.

[0143] For example, the second DCI includes one or more TDRA information fields, and one TDRA information field indicates one row of TDRA configuration. The TDRA tables corresponding to different time domain resource allocation information fields may be the same or different.

[0144] For example, the second DCI includes one TDRA information field (corresponding to the first information in the second indication information), which is used to indicate the second time domain resource corresponding to the ON state and / or the OFF state. Assuming that the second DCI is also 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 transmission operation of the transmission unit (indicating that the transmission unit is ON and / or OFF), the TDRA field is used to indicate the second time domain resource corresponding to the ON state and / or the OFF state of the transmission unit. In either case, the TDRA tables corresponding to the TDRA information fields may be the same or different. That is, the TDRA tables to which the second time domain resource and the fourth time domain resource are applied may be the same or different.

[0145] For example, the second DCI may include two TDRA fields, one of which is used to indicate the second time domain resource corresponding to the ON state and / or OFF state of the transmitter, and the other of which is used to indicate the fourth time domain resource corresponding to the PDSCH / PUSCH of the NCR-MT, thereby enabling the second DCI to support both scheduling the PDSCH / PUSCH of the NCR-MT and controlling the transmission operation of the transmitter (indicating that the transmitter is ON and / or OFF).

[0146] For example, the second DCI may include two TDRA fields, one of which is used to indicate the second time domain resource corresponding to the ON state and / or the OFF state of the transmission unit, and the other of which is used to indicate the first time domain resource corresponding to the access link beam. In either case, the TDRA tables corresponding to the TDRA information fields may be the same or different. That is, the TDRA tables to which the second time domain resource and the first time domain resource are applied may be the same or different.

[0147] In the above example, the repeater can support one or more of the above methods. The method may further include the repeater reporting capability information to the network device. The capability information is used to notify the network device of the information indication methods supported by the repeater. Based on the capability information, the network device can control the on and / or off state of its forwarding unit in the method supported by the repeater.

[0148] In some embodiments, the second indication included in the second DCI includes only third information, which is used to indicate that the forwarder is in an OFF state, the OFF state having a higher priority than the ON state implicitly indicated by the first indication carried by the first RRC signaling and / or the first MAC signaling and / or a lower priority than the ON state implicitly indicated by the first indication carried by the first DCI.

[0149] In some embodiments, if the first indication information is included in the DCI, the second indication information is not included, and vice versa, i.e., including both the first indication information and the second indication information in the DCI is an erroneous configuration, and the network device should avoid such a configuration.

[0150] In the above example, one TDRA information field (the bit value of the information field is the configured row number) is used to indicate a TDRA configuration similar to the above second configuration information, and the TDRA configuration (one first information) includes at least one fourth time length information and / or at least one fourth offset information of the second time domain resource. The fourth offset information may correspond to the above K0 configuration, and the fourth offset information means an offset between the start position of the second time domain resource and the end position of the PDCCH on which the second DCI is carried. However, the embodiment of the present invention is not limited thereto. For example, the fourth offset may be an offset between the start position of the second time domain resource corresponding to one state and the end position of the second time domain resource corresponding to the immediately adjacent state.

[0151] In some embodiments, the TDRA configuration may include at least one fourth time length information and / or at least one fourth offset information of the second time domain resource. The fourth time length and / or fourth offset include at least one time unit, and the first information indicates the number of time units to indicate the fourth time length and / or fourth offset. The at least one time unit may be contiguous across the time domain, or the at least one time unit may not be contiguous across the time domain. The time unit may be, for example, a subframe, a slot, a symbol, a mini-slot, a millisecond, etc. That is, the fourth time length may include a millisecond-level time length, a slot-level time length, and / or a symbol-level time length, and the fourth offset may include a millisecond-level offset, a slot-level offset, and / or a symbol-level offset. The second time domain resource (length of the time unit) is related to the subcarrier spacing, and the time unit of the at least one fourth time length information may be the same or different, and the time unit of the at least one fourth offset information may be the same or different. A method for determining the second time domain resource based on the subcarrier spacing will be described later. Explanations of the same content as in "I" will be omitted.

[0152] 10A to 10G are schematic diagrams of second instruction information according to an embodiment of the present invention. As shown in FIG. 10A, the indicated state is an on state, corresponding to one fourth offset and one fourth time length. As shown in FIG. 10B, the indicated states are an on state and an off state, corresponding to one fourth offset and one fourth time length, where the fourth time length of each state may be determined according to implementation. As shown in FIG. 10C, the indicated states are an on state and an off state, corresponding to one fourth offset and two fourth time lengths, where the two fourth time lengths correspond to the on state and the off state, respectively. As shown in FIG. 10D, the indicated states are an on state and an off state, corresponding to two fourth offsets and two fourth time lengths, where the reference positions of the fourth offsets are the same and the two fourth time lengths are the same. As shown in FIG. 10E, the commanded states are an on state and an off state, and correspond 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 commanded states are an on state and an off state, and correspond 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 commanded states are an on state and an off state, and correspond 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. FIGS. 10F and 10G differ from FIG. 10E in that the reference position of the fourth offset 2 is different.

[0153] Although the second time domain resources in the above Figures 10A to 10G are continuous, this is not limited to this and they may be discontinuous (for example, one state may correspond to multiple fourth offsets and / or fourth time length information and constitute discontinuous time domain resources).

[0154] In some embodiments, the second time domain resources corresponding to the ON state and / or the OFF state indicated by the second indication information may overlap (partially or completely). For example, the received second RRC signaling includes a plurality of second configuration information (second indication information), and the second time domain resources corresponding to the ON state and / or the OFF state indicated by different second indication information may overlap. Therefore, the method further includes determining whether the repeater is in the ON state or the OFF state in the overlapping second time domain resources based on an instruction from the network device and / or a predefined method.

[0155] In some embodiments, the repeater may determine whether to be in an on state or an off state in the second time domain resource of the overlapping portion based on an instruction from the network device.

[0156] For example, the second instruction information may further include priority information, identification information, and / or packet information. The repeater adopts the state indicated by the second instruction information having the highest corresponding priority and / or the lowest corresponding identifier. Here, the identifier may be determined based on the identification information and / or packet information.

[0157] The above is merely an example, and the priority information and / or identification information and / or packet information may not be included in the second instruction information, but may be included in the fourth instruction information separately transmitted by the network device, and the embodiment of the present invention is not limited thereto.

[0158] In some embodiments, the repeater may determine whether the second time domain resource of the overlapping portion should be in an ON state or an OFF state according to a predefined rule.

[0159] For example, the forwarding unit of the repeater is in the on state as long as one of the plurality of second instruction information causing the above overlap indicates the on state.

[0160] Furthermore, for example, if multiple pieces of second instruction information (second configuration information) that cause the above-mentioned overlap are included in the same list (same configuration list), the repeater determines which instruction to use based on the position / order of the second instruction information in the list. For example, if the multiple pieces of second instruction information include the first piece of second instruction information in the list, the state indicated by the first piece of second instruction information takes precedence, and if the multiple pieces of second instruction information include the second piece of second instruction information in the list but do not include the first piece of second instruction information in the list, the state indicated by the second piece of second instruction information takes precedence.

[0161] (3) Related to the third instruction information In some embodiments, the backhaul link beam may also be referred to as a network device-side beam, and refers to a receive beam / transmit beam that a repeater employs in the backhaul link. Here, the (antenna) beam refers to, for example, the main lobe of the radiation pattern of an antenna array. Since the beam implementation is similar to the AC link beam, please refer to (1) for details.

[0162] In some embodiments, the third instruction information includes backhaul link beam instruction information, and / or identification information, and / or packet information, and / or priority information, and / or first information indicating a third time domain resource corresponding to the backhaul link beam.

[0163] In some embodiments, the third indication information is carried by at least one of third RRC signaling, third MAC signaling, or third PHY signaling. Here, the third PHY signaling may be a third DCI, such as a unicast DCI or a group common DCI. Meanwhile, the format of the third DCI may be a conventional DCI format (e.g., 1_1, 2_0) or a newly introduced DCI format. The third RRC signaling, third MAC signaling, or third PHY signaling may be the same as or different from the above-mentioned first RRC signaling, first MAC signaling, first PHY signaling, second RRC signaling, second MAC signaling, or second PHY signaling.

[0164] The information and delivery method in the third instruction information are the same as those in the first instruction information, and therefore, the description thereof will be omitted here.

[0165] For example, if the third time domain resource is periodic or semi-persistent, the first information includes information indicating the third time domain resource within one period and / or period information, and the information indicating the third time domain resource within one period includes at least one fifth time length information and / or fifth offset information of the third time domain resource.

[0166] For example, if the third time domain resource is aperiodic, the first information includes at least one sixth time length information and / or at least one sixth offset information indicating the third time domain resource.

[0167] In some embodiments, the periodicity, the fifth time length, the fifth offset, and / or the sixth time length and / or the sixth offset includes at least one time unit. The first information indicates the periodicity, the fifth time length, the fifth offset, and / or the sixth time length and / or the sixth offset by indicating the number of time units. The at least one time unit is continuous across the time domain or discontinuous across the time domain. The time unit may be, for example, a subframe, a slot, a symbol, a mini-slot, or a millisecond. That is, the fifth time length and / or the sixth time length include a millisecond-level time length and / or a slot-level time length and / or a symbol-level time length, and the fifth offset and / or the sixth offset include a millisecond-level offset and / or a slot-level offset and / or a symbol-level offset. The third time domain resource (length of the time unit) is related to the subcarrier spacing.

[0168] (4) Subcarrier spacing In the above embodiment, a time unit of the first time length and / or period and / or second time length corresponding to the first time domain resource is associated with the first subcarrier spacing, a time unit of the first offset and / or second offset corresponding to the first time domain resource is associated with the second subcarrier spacing, a time unit of the third time length and / or period and / or fourth time length corresponding to the second time domain resource is associated with the third subcarrier spacing, a time unit of the third offset and / or fourth offset corresponding to the second time domain resource is associated with the fourth subcarrier spacing, a time unit of the fifth time length and / or period and / or sixth time length corresponding to the third time domain resource is associated with the fifth subcarrier spacing, and a time unit of the fifth offset and / or sixth offset corresponding to the third time domain resource is associated with the sixth subcarrier spacing.

[0169] In some embodiments, the repeater determines the time domain resource based on the subcarrier spacing, where the repeater uses the first subcarrier spacing and / or the second subcarrier spacing to determine the first time domain resource, uses the third subcarrier spacing and / or the fourth subcarrier spacing to determine the second time domain resource, and uses the fifth subcarrier spacing and / or the sixth subcarrier spacing to determine the third time domain resource.

[0170] In some embodiments, to enable the repeater to determine the time domain resource, the repeater needs to determine which subcarrier spacing the time unit of the time domain resource is based on. 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 the second information transmitted 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 may be the same or different.

[0171] 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 in accordance with communication standard definition rules. The communication standard definition rule includes that 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 fixed, or is a reference subcarrier spacing for a TDD configuration, or is a subcarrier spacing for an uplink / downlink activation BWP of a repeater, or is a subcarrier spacing for a PDSCH or PDCCH carrying all or part of the indication information, or is a subcarrier spacing for a PUCCH carrying HARQ feedback for a PDSCH or PDCCH carrying all or part of the indication information, or is a maximum or minimum value of the subcarrier spacing for a downlink and / or uplink configuration BWP of a repeater, or is a maximum or minimum value of the subcarrier spacing for an SSB, or is a maximum or minimum value of the subcarrier spacing for a PRACH, or is a maximum or minimum value of the subcarrier spacing for a downlink and / or uplink carrier, or is a maximum or minimum value of the subcarrier spacing for at least two of the above subcarrier spacings.

[0172] In some embodiments, the reference subcarrier spacing of the TDD configuration may be predefined or configured by higher layer signaling. The TDD configuration may include, for example, a semi-static TDD configuration and / or a dynamic TDD configuration. For example, the semi-static TDD configuration may be provided by a network device via higher layer signaling at the cell level / user-specific level (e.g., tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated). For example, the dynamic TDD configuration may be provided by SFI / DCI format 2_0 (DCI format 2_0 includes SFI). One time unit (e.g., symbol, slot, subframe) may be configured as uplink, downlink, or flexible. Here, if a time unit is semi-statically configured as uplink, it must not be rewritten as downlink or flexible by SFI / DCI format 2_0 (it is invalid for SFI / DCI format 2_0 to specify this time unit as downlink or flexible). Similarly, if a time unit is semi-statically configured as downlink, it must not be rewritten as uplink or flexible by SFI / DCI format 2_0 (it is invalid for SFI / DCI format 2_0 to specify this time unit as 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 (the default is flexible), SFI / DCI format 2_0 may configure the time unit as uplink, downlink, or flexible.

[0173] 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 by different higher layer signaling, e.g., different RRC IEs / fields.

[0174] In some embodiments, the subcarrier spacing of the TDD configuration includes a subcarrier spacing for the downlink and / or a subcarrier spacing for the uplink. For example, for FDD, the above TDD configuration is also applicable (but not limited to) when a mobile terminal does not simultaneously support receiving a downlink signal on a downlink carrier in an FDD band and transmitting an uplink signal on an uplink carrier in the FDD band, and the above higher layer signaling and / or SFI / DCI format 2_0 is used to instruct the mobile terminal to receive a downlink signal on a downlink carrier or transmit an uplink signal on an uplink carrier within one time unit. In this case, the reference subcarrier spacing for the downlink and uplink may be the same or different.

[0175] 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 reference subcarrier spacings for the TDD configuration (i.e., are the same as the reference subcarrier spacings for the TDD configuration), and the corresponding reference subcarrier spacings for the TDD configuration are different for the indication information carried by different signaling (or beam / on / off configurations with different time-domain characteristics). For example, for the first indication information carried only by RRC signaling (or semi-static access link beam configuration), the first subcarrier spacing and / or the second subcarrier spacing are the reference subcarrier spacings for the semi-static TDD configuration. Also, for 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 are the reference subcarrier spacings for the dynamic TDD configuration. Alternatively, for example, for the second instruction information (or semi-static on / off configuration) carried only by RRC signaling, the third subcarrier spacing and / or the fourth subcarrier spacing are reference subcarrier spacings for a semi-static TDD configuration. Also, for example, for the second instruction information (or dynamic on / off configuration) carried by DCI, the third subcarrier spacing and / or the fourth subcarrier spacing are reference subcarrier spacings for a dynamic TDD configuration. Alternatively, for example, for the third instruction information (semi-static backhaul link beam configuration) carried only by RRC signaling, the fifth subcarrier spacing and / or the sixth subcarrier spacing are reference subcarrier spacings for a semi-static TDD configuration. In another example, for the third instruction information (or dynamic backhaul link beam) carried by DCI, the fifth subcarrier spacing and / or the sixth subcarrier spacing are reference subcarrier spacings for a dynamic TDD configuration.

[0176] 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 indicated by second information transmitted by the network device, the second information including one or more subcarrier spacing indication information, the one or more subcarrier spacing indication information indicating 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.

[0177] 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 multiple beams, or corresponds to one first indication information (access link beam indication information) or multiple first indication information (access link beam indication information).

[0178] For example, one first subcarrier spacing indication and / or one second subcarrier spacing indication is applied to one access link indication (or first indication), where one access link indication (or first indication) indicates one or more beams, and the one or more beams each apply one first subcarrier spacing indication and / or one second subcarrier spacing indication, i.e., the same first subcarrier spacing indication is applied to the first duration and / or second duration of the first time domain resources corresponding to one or more beams, and the same second subcarrier spacing indication is applied to the first offset and / or second offset of the first time domain resources corresponding to one or more beams. Here, the first subcarrier spacing indication information and / or the second subcarrier spacing indication information may be included in the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling, or may be 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 may be included in a fourth RRC signaling and / or a fourth MAC signaling and / or a fourth PHY signaling different from the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling. For example, each first instruction information (access link beam instruction information) includes one first subcarrier spacing instruction information and / or one second subcarrier spacing instruction information, or the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling each include multiple (N) first subcarrier spacing instruction information and / or multiple (N) second subcarrier spacing instruction information corresponding to the multiple (N) first instruction information (access link beam instruction information) in the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling, respectively.

[0179] For example, one first subcarrier spacing indication and / or one second subcarrier spacing indication is applied to one access link beam, where one access link indication (or first indication) indicates multiple beams, and the multiple beams apply different first subcarrier spacing indications and / or different second subcarrier spacing indications, i.e., different first subcarrier spacing indications are applied to the first lengths and / or second lengths of the first time domain resources corresponding to the multiple beams, and different second subcarrier spacing indications are applied to the first offsets and / or second offsets of the first time domain resources corresponding to the multiple beams. Here, the different first subcarrier spacing indication information and / or the different second subcarrier spacing indication information may be included in the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling, or may be 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 may be included in a fourth RRC signaling and / or a fourth MAC signaling and / or a fourth PHY signaling that is different from the first RRC signaling and / or the first MAC signaling and / or the first PHY signaling.

[0180] For example, one first subcarrier spacing indication and / or one second subcarrier spacing indication is applied to one or more access link beam indications (first indications), where one access link indication (or first indication) indicates one or more beams, and each of the one or more access link beam indications (first indications) applies one first subcarrier spacing indication and / or one second subcarrier spacing indication. That is, the same first subcarrier spacing indication information is applied to the first time length and / or second time length 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, and the same second subcarrier spacing indication information is applied to the first offset and / or second offset 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.

[0181] 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 an on state and / or an off state, or corresponds to one second indication information or multiple second indication information.

[0182] For example, one third subcarrier spacing indication and / or one fourth subcarrier spacing indication is applied to one state. Here, the plurality of second indications indicate an ON state and / or an OFF state, where the ON state corresponds to one third subcarrier spacing indication and / or one fourth subcarrier spacing indication, and the OFF state corresponds to one third subcarrier spacing indication and / or one fourth subcarrier spacing indication. That is, the third duration and / or fourth duration of the second time domain resource corresponding to the ON state are applied with one third subcarrier spacing indication, the third duration and / or fourth duration of the second time domain resource corresponding to the OFF state are applied with another third subcarrier spacing indication, the third offset and / or fourth offset of the second time domain resource corresponding to the OFF state are applied with one fourth subcarrier spacing indication, and the third offset and / or fourth offset of the second time domain resource corresponding to the ON state are applied with another fourth subcarrier spacing indication. Here, the third subcarrier spacing indication information and / or the fourth subcarrier spacing indication information may be included in the second RRC signaling and / or the second MAC signaling and / or the second PHY signaling, or may be included in fourth RRC signaling and / or fourth MAC signaling and / or fourth PHY signaling different from the second RRC signaling and / or the second MAC signaling and / or the second PHY signaling. For example, the second (fourth) RRC signaling and / or the second (fourth) MAC signaling and / or the second (fourth) PHY signaling includes two third subcarrier spacing indication information and / or two fourth subcarrier spacing indication information, and the second time domain resources corresponding to the on state and the off state indicated by the second indication information indicated by the second RRC signaling and / or the second MAC signaling and / or the second PHY signaling respectively apply two different third subcarrier spacing indication information or respectively apply two different fourth subcarrier spacing indication information.

[0183] For example, one third subcarrier spacing indication and / or one fourth subcarrier spacing indication is applied to one second indication, and the one second indication indicates an ON state and / or an OFF state. Different second indications apply different third subcarrier spacing indications and / or different fourth subcarrier spacing indications. That is, one second indication indicates that the third duration and / or fourth duration of the second time domain resource corresponding to the ON state and / or the OFF state applies the one third subcarrier spacing indication, and one second indication indicates that the third offset and / or fourth offset of the second time domain resource corresponding to the ON state and / or the OFF state applies the one fourth subcarrier spacing indication. Here, the third subcarrier spacing indication information and / or the fourth subcarrier spacing indication information may be included in the second RRC signaling and / or the second MAC signaling and / or the second PHY signaling, or may be included in the second indication information of the second RRC signaling and / or the second MAC signaling and / or the second PHY signaling, or may be included in fourth RRC signaling and / or fourth MAC signaling and / or fourth PHY signaling different from the second RRC signaling and / or the second MAC signaling and / or the second PHY signaling. For example, each second indication information includes one third subcarrier spacing indication information and / or one fourth subcarrier spacing indication information, or the second RRC signaling and / or the second MAC signaling and / or the second PHY signaling includes a plurality of third subcarrier spacing indication information and / or a plurality of fourth subcarrier spacing indication information corresponding to the plurality of second indication information in the second RRC signaling and / or the second MAC signaling and / or the second PHY signaling, respectively.

[0184] For example, one or more third subcarrier spacing indications and / or one or more fourth subcarrier spacing indications are applied to one or more second indications, where each of the multiple second indications applies one or more third subcarrier spacing indications and / or one or more fourth subcarrier spacing indications, i.e., the same third subcarrier spacing indication is applied to the third duration and / or fourth duration of the second time domain resource corresponding to the ON state and / or OFF state indicated by the multiple second indications in the second RRC signaling and / or the second MAC signaling and / or the second PHY signaling, and the same fourth subcarrier spacing indication is applied to the third offset and / or fourth offset of the second time domain resource corresponding to the ON state and / or OFF state indicated by the multiple second indications in the second RRC signaling and / or the second MAC signaling and / or the second PHY signaling. Here, the third subcarrier spacing indication information and / or the fourth subcarrier spacing indication information may be included in the second RRC signaling and / or the second MAC signaling and / or the second PHY signaling, or may be included in fourth RRC signaling and / or fourth MAC signaling and / or fourth PHY signaling different from the second RRC signaling and / or the second MAC signaling and / or the second PHY signaling. For example, the second (fourth) RRC signaling and / or the second (fourth) MAC signaling and / or the second (fourth) PHY signaling includes third subcarrier spacing indication information and / or fourth subcarrier spacing indication information, and the second indication information indicated by the second RRC signaling and / or the second MAC signaling and / or the second PHY signaling applies one third subcarrier spacing indication information and / or one fourth subcarrier spacing indication information.
