Description

[Technical Field]

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

[0002] Compared to conventional 3G and 4G systems, 5G systems can offer greater bandwidth and higher data rates, and can support a wider variety of terminal types and vertical services.

[0003] Therefore, in addition to the conventional telecommunications frequency spectrum, 5G systems will also be deployed in a new frequency spectrum, and the frequencies of this new frequency spectrum are significantly higher than the conventional telecommunications frequency spectrum used by 3G and 4G systems. For example, 5G systems can be deployed in the millimeter wave band (28GHz, 38GHz, 60GHz, etc.).

[0004] According to the laws of radio signal propagation, the higher the frequency of the carrier in which the signal is located, the more severe the fading encountered during propagation becomes. Therefore, in actual deployments, 5G systems, especially those deployed in the millimeter-wave band, require methods to enhance coverage compared to conventional 3G and 4G systems. How to better enhance the cell coverage of 5G systems remains a pending issue.

[0005] The above-mentioned introduction of background art is intended to clearly and completely explain the proposed technical aspects of the present invention and to facilitate understanding by those skilled in the art. These technical aspects, as described in the background art of the present invention, should not be construed as being well-known to those skilled in the art. [Overview of the project] [Problems that the invention aims to solve]

[0006] To better address the coverage issues of cellular mobile communication systems in actual deployments, employing RF repeaters to amplify and forward signals between terminal and network equipment (also known as amplified forwarding) is a commonly used deployment method. RF repeaters are widely applied in the actual deployments of 3G and 4G systems. Generally speaking, conventional RF repeaters are devices that amplify and forward round-trip signals between devices in the RF domain. In other words, conventional RF repeaters are non-regenerative relay nodes; they simply amplify and forward all received signals directly.

[0007] The inventors discovered the following: Conventional RF transceivers cannot interact with other devices (e.g., network devices / terminal devices, etc.). Specifically, in terms of reception, conventional RF transceivers do not support measurement / demodulation / decoding of the transmitted signal, nor do they receive signals other than the transmitted signal. In terms of transmission, conventional RF transceivers only amplify and transmit signals, and do not support generating signals or transmitting signals they generate themselves. Therefore, the transmission behavior of conventional RF transceivers is not subject to network control (e.g., control by network devices, etc.). For example, the on / off state of a transceiver is usually set manually.

[0008] The inventor also discovered the following: Conventional transceivers are typically manually switched on and off, which cannot dynamically match data transmission between network devices and UEs. Since data transmission between network devices and terminal devices is not always constant, if a transceiver remains open even when there is no data transmission, it can unnecessarily increase power consumption, interfere with other devices, and reduce network throughput. Therefore, a new on / off function for the transceiver is needed compared to conventional transceivers. However, there is currently no concrete method for controlling the open / closed state.

[0009] In view of at least one of the above-mentioned problems, embodiments of the present invention provide an information instruction method, a transfer device, and network equipment. [Means for solving the problem]

[0010] According to one aspect of the embodiments of the present invention, a transfer device is provided, which is, The transfer device includes a receiving unit that receives first control information at the mobile terminal, The first control information includes at least first information for indicating time-domain resources, The transfer unit of the transfer device is in a first, second, or third state in the time-domain resource indicated by the first information.

[0011] Furthermore, according to another aspect of the embodiment of the present invention, a network device is provided which includes a transmitting unit, The transmitting unit transmits first control information to the transfer unit, the first control information including at least first information for indicating a time-domain resource; and / or transmits or does not transmit second control information, the second control information used to instruct the transfer unit to transfer a signal on the time-domain resource.

[0012] Furthermore, according to yet another aspect of the embodiments of the present invention, a communication system is provided which includes the transceiver and / or network equipment described in the aforementioned aspect. [Effects of the Invention]

[0013] The advantageous effects of the embodiments of the present invention are at least as follows: By controlling the opening and closing of the transceiver using first control information, the time-domain resources corresponding to the open state of the transceiver are made to match the time-domain resources for data transmission between network devices and terminal devices. This saves power consumption of the transceiver, reduces interference with other devices in the network, and improves network throughput.

It should be understood that the present invention is not limited to the described embodiments, that is, the present invention also includes all changes, modifications and alternatives within the scope of the appended patent claims.

[0020] In an embodiment of the present invention, the term "communication network" or "wireless communication network" may refer to a network conforming to any of the following communication standards, for example, LTE (Long Term Evolution), LTE-A (LTE-Advanced), WCDMA (registered trademark) (Wideband Code Division Multiple Access), HSPA (High-Speed Packet Access), etc.

[0021] Furthermore, communication between devices in a communication system may be carried out according to any stage of communication protocol, and may include, but is not limited to, the following communication protocols: namely, 1G (generation), 2G, 2.5G, 2.75G, 3G, 4G, 4.5G, 5G, New Radio (NR), and / or other conventional or future-developed communication protocols.

[0022] In embodiments of the present invention, the term "network equipment" refers, for example, to a device in a communication system that connects terminal equipment to a communication network and provides services to said terminal equipment. Network equipment may include, but is not limited to, the following: base stations (BS), access points (AP), transmission and reception points (TRP), broadcast transmitters, mobile management entities (MME), network gateways, servers, radio network controllers (RNC), base station controllers (BSC), etc.

[0023] Base stations may include, but are not limited to, Node B (NodeB or NB), Evolutionary Node B (eNodeB or eNB), 5G base stations (gNB), and may also include RRH (Remote Radio Head), RRU (Remote Radio Unit), relays, low-power nodes (e.g., femto, pico, etc.). The term "base station" may also include some or all of these functions, and each base station can provide communication coverage to a specific geographic area. The term "cell" may refer to a base station and / or the area it covers, depending on the context in which the term is used. Cells and base stations are interchangeable as long as it does not cause confusion.

[0024] In embodiments of the present invention, the terms "User Equipment" (UE) or "Terminal Equipment" (TE) refer to devices that access a communication network via network equipment and receive services from the network. User equipment may be fixed or mobile, and may also be referred to as a mobile station (MS), terminal, subscriber station (SS), access terminal (AT), station, etc.

[0025] Terminal devices may include, but are not limited to, the following: cellular phones, PDAs (Personal Digital Assistants), wireless modems, wireless communication devices, mobile devices, machine-type communication devices, laptop computers, cordless telephones, smartphones, smartwatches, digital cameras, etc.

[0026] Furthermore, in scenarios such as IoT (Internet of Things), user devices may also be monitoring or measuring devices or equipment, and may include, but are not limited to, the following: machine-type communication (MTC) terminals, in-vehicle communication terminals, D2D (device-to-device) terminals, M2M (machine-to-machine) terminals, etc.

[0027] Furthermore, the terms “network side” or “network equipment side” refer to the network side, which may be a base station or include one or more network devices as described above. The terms “user side” or “terminal side” or “terminal equipment side” refer to the user or terminal side, which may be a UE or include one or more terminal devices as described above. Unless otherwise specified, “equipment” may refer to network equipment or terminal equipment.

[0028] In embodiments of the present invention, existing business operations (services / traffic) or future business operations may be transmitted between network equipment and terminal equipment. For example, these operations may include, but are not limited to, eMBB, mMTC, URLLC, V2X communication, etc.

[0029] Conventional transceivers lack the ability to communicate with network equipment. While they can be useful for boosting signal strength, they lack flexibility and cannot adapt to complex environmental changes. Deploying conventional transceivers in 5G networks (especially high-frequency 5G networks) can cause unnecessary interference with other network equipment and / or terminal devices, reducing the overall transmission efficiency (e.g., throughput) of the network. To make transceiver forwarding more flexible and adaptable to the characteristics of 5G networks, network equipment needs to cooperate with transceivers and be able to configure transceiver forwarding according to network conditions.

[0030] In 3GPP Rel-18, a network-controlled repeater (NCR) scheme is proposed for signal transfer between network devices and terminal devices to enhance NR coverage. The NCR can communicate directly with the network device via a control link to assist in the NCR's transfer operations.

[0031] Figure 1 shows an NCR in an embodiment of the present invention. As shown in Figure 1, the NCR 102 is configured between a network device 101 and a terminal device 103. The NCR 102 may include two modules / components, namely, a mobile terminal for the transceiver (NCR-MT) and a forwarding unit for the transceiver (NCR-Fwd). The NCR-Fwd is also called the routing unit for the NCR (NCR-RU). The NCR-MT is used to communicate (interact with information) with the network device, and the NCR-Fwd is used to forward round-trip signals between the network device and the terminal device. The NCR-MT and NCR-Fwd are functional entities, and their functions can be realized by the same or different hardware modules.

[0032] As shown in Figure 1, the NCR in this embodiment of the present invention has three links: a control link (C-link), a backhaul link (BH link) for forwarding, and an access link (AC link). Of these, the C-link is used for communication between the NCR and network equipment. The BH link is used for the transceiver to receive forwarding signals from network equipment or to forward signals from terminal equipment to network equipment. The AC link is used for the transceiver to forward signals from network equipment to terminal equipment or to receive forwarding signals from terminal equipment. Specifically, the NCR-MT communicates with network equipment via the C-link, and the NCR-Fwd forwards signals via the BH link and AC link.

[0033] In embodiments of the present invention, a transporter can communicate with network equipment, receive communication channels / signals transmitted by network equipment, and obtain information transmitted by network equipment to the transporter by demodulating / decoding the channels / signals; this signal processing process is hereinafter referred to as "communication." The transporter can further transfer channels / signals transmitted between network equipment and terminal equipment; the transporter can perform processing such as amplification without demodulating / decoding the channels / signals; this signal processing process is hereinafter referred to as "transfer." "Communication" and "transfer" are collectively referred to as "transmission." Also, "transmitting or receiving over an AC (or BH) link" is equivalent to "transferring over an AC (or BH) link," and "transmitting or receiving over a control link" is equivalent to "communicating over a control link." These terms are for illustrative purposes only and do not limit the present invention. In some cases, "transfer unit" is interchangeable with "transferring behavior."

[0034] In embodiments of the present invention, the transponder may further be called a network-controlled transponder (NCR), repeater, RF transponder, repeater, RF repeater; or a repeater node, transponder node, repeater node; or a smart repeater, smart transponder, smart repeater, smart repeater node, smart transponder node, smart repeater node, but the present invention is not limited thereto.

[0035] In embodiments of the present invention, the network device may be a device in the serving cell of a terminal device, a device in the cell where the transceiver is located, a device in the serving cell of the transceiver, or the parent node of the transceiver. However, the present invention does not limit the name of the transceiver, and any device capable of realizing the above-described functions falls within the scope of the transceiver of the present invention.

[0036] The following describes various embodiments of the present invention in conjunction with the drawings. These embodiments are merely illustrative and do not limit the present invention.

[0037] <Example of the first side view> An information instruction method is provided in an embodiment of the present invention, and the explanation will be given from the perspective of the transfer device.

[0038] Figure 2 is a diagram showing an information display method in an embodiment of the present invention. As shown in Figure 2, the method includes the following operations (steps): 201: The mobile terminal of the transporter receives first control information, which includes at least first information for indicating a time-domain resource. The transporter's transport unit is in a first, second, or third state with respect to the time-domain resource indicated by the first information.

[0039] Figure 2 above is provided to illustrate an embodiment of the present invention, but the present invention is not limited thereto. For example, the execution order between each operation can be appropriately adjusted, or some operations can be added or removed. Those skilled in the art can make appropriate modifications based on the above description without being limited to Figure 2.

[0040] In some embodiments, the first state may be referred to as the open (ON) state or first open state, the second state as the standby state or switching state or second open state or second closed state, and the third state as the closed (OFF) state or shutdown state or first closed state.

[0041] In some embodiments, the first, second, and third states refer to the states of the forwarding unit (NCR-Fwd) of the transceiver. As described above, the NCR-Fwd is used to transfer round-trip signals between network devices and terminal devices, and the first, second, or third states described above are used to represent the working state or open / closed state of the NCR-Fwd.

[0042] In some embodiments, the first state represents the NCR-Fwd transferring a signal. For example, when a transfer unit is in the first state during a period (or time-domain resource) A, it means that the transfer unit is transferring a signal during that period, which includes transferring downlink signals that network equipment transmits to terminal equipment, and / or transferring uplink signals that terminal equipment transmits to network equipment. If the transfer unit transfers downlink and uplink signals in a time-division multiplexer during that period, and / or uses different BH link beams and / or AC link beams in a time-division multiplexer to transfer signals, the period includes the time during which the transfer unit performs uplink / downlink switching and / or beam switching.

[0043] In some embodiments, the second state indicates that the NCR-Fwd is permitted to transfer a signal, has the capability to transfer a signal, or is ready to transfer a signal. For example, when a transfer unit is in the second state during a period (or time domain resource) B, the transfer unit is in a standby state during that period, or the transfer unit stops transferring a signal during that period, or the transfer unit does not transfer a signal during that period, or the transfer unit has the capability to transfer a signal during that period (or is permitted to transfer a signal, or is able to, or is capable of, or is ready to)

[0044] In some embodiments, the third state represents that the NCR-Fwd is not permitted to transfer signals, does not have the ability to transfer signals, or is not ready to transfer signals. For example, when a transfer unit is in the third state during a period (or time-domain resource) C, the transfer unit is shut down during that period, or the transfer unit stops transferring signals during that period, or the transfer unit does not transfer signals during that period, or the transfer unit has the ability to transfer signals during that period (or is permitted to, or is able to, or is capable of, or is ready to), or the transfer unit does not have the ability to transfer signals during that period (or is not permitted to, or is not able to, or is not capable of, or is not ready to).

[0045] In some embodiments, the NCR supports a first state, for which output power requirements may be defined, for example, the output power when the NCR is in the first state is not less than or greater than the first power (or power level), and / or the output power when the NCR is in the first state is not greater than or less than the fourth power (or power level).

[0046] In some embodiments, NCR (or NCR-Fwd) supports only one of the second and third states. For example, NCR supports the first and second states, or the first and third states.

[0047] In some embodiments, NCR (or NCR-Fwd) supports a second and a third state. For example, NCR supports a first, second, and third state.

[0048] In some embodiments, the NCR (or NCR-MT) can report to the network device whether it supports the second and / or third state.

[0049] In some embodiments, the output power requirements are defined for the second state only or the third state only, for example, the output power when the NCR is in the second or third state is not greater than or less than the second power (or power level) described below.

[0050] In some embodiments, the output power requirements are defined for both the second and third states.

[0051] In some embodiments, the output power requirements for the second and third states are the same; for example, the output power when the NCR is in the second and third states is no greater than or less than the second power (or power level) described below.

[0052] In some embodiments, the output power requirements differ when NCR-Fwd is in the second and third states. For example, when NCR-Fwd is in the second state, the output power of NCR-Fwd is no greater than or less than the second power, and when NCR-Fwd is in the third state, the output power of NCR-Fwd is no greater than or less than the third power. The values ​​of the second and third powers are different; for example, the second power is greater than the third power.

[0053] In some embodiments, the second power / third power refers to the power spectral density (dBm / MHz), and may be referred to as the second power spectral density and the third power spectral density, respectively. For example, the second power is equal to -85 dBm / MHz and the third power is less than -85 dBm / MHz, or the second power is greater than -85 dBm / MHz and the third power is equal to -85 dBm / MHz. Also, for example, the second power is -50 dBm / (SCS × (12 × N RB The third power is equal to (+1) / 1000)MHz, and the third power is -50dBm / (SCS × (12 × N) RBLess than +1) / 1000)MHz; or the second power is -50dBm / (SCS × (12 × N RB The third power is greater than +1) / 1000)MHz, and the third power is -50dBm / (SCS×(12×N RB The subcarrier spacing (SCS) is equal to (+1) / 1000)MHz, and is, for example, the SCS of the transmitted signal (not the signal being transmitted). Also, for example, the second power is equal to -36dBm / MHz and the third power is less than -36dBm / MHz, or the second power is greater than -36dBm / MHz and the third power is equal to -36dBm / MHz.

[0054] In some embodiments, the output power requirements for NCR-Fwd may be defined for the uplink and downlink respectively, in other words, the second and / or third powers described above may be defined for the output power of the BH link and AC link, respectively. For example, for the output power of the downlink or AC link, the second power may be equal to -85 dBm / MHz and the third power may be less than -85 dBm / MHz, or the second power may be greater than -85 dBm / MHz and the third power may be equal to -85 dBm / MHz, and for the output power of the uplink or BH link, the second power may be -50 dBm / (SCS × (12 × N RB The third power is equal to (+1) / 1000)MHz, and the third power is -50dBm / (SCS × (12 × N) RB Less than +1) / 1000)MHz; or the second power is -50dBm / (SCS × (12 × N RB The third power is greater than +1) / 1000)MHz, and the third power is -50dBm / (SCS×(12×N RB The subcarrier interval SCS is equal to (+1) / 1000)MHz, and is, for example, the SCS of the transmitted signal (not the signal being transmitted), but is not limited to this.

[0055] In some embodiments, the requirements for the output power can be defined for different working frequency bands or frequency ranges (e.g., FR1, FR2, FR2-1, FR2-2). In other words, the above-mentioned second power and / or third power are defined respectively for the output power of NCR-Fwd working in different frequency bands or frequency ranges. For example, for the downlink or AC link output power of FR1, the second power is equal to -85 dBm / MHz, and the third power is less than -85 dBm / MHz, or the second power is greater than -85 dBm / MHz, and the third power is equal to -85 dBm / MHz. For the uplink or BH link output power of FR1, the second power is equal to -50 dBm / (SCS×(12×N RB +1) / 1000)MHz, and the third power is less than -50 dBm / (SCS×(12×N RB +1) / 1000)MHz; or the second power is greater than -50 dBm / (SCS*(12*N RB +1) / 1000)MHz, and the third power is equal to -50 dBm / (SCS×(12×N RB +1) / 1000)MHz. The subcarrier spacing SCS is, for example, but not limited to, the SCS of the transmission signal (not the signal during transmission). Also, for example, for the output power of FR2, the second power is equal to -36 dBm / MHz, and the third power is less than -36 dBm / MHz, or the second power is greater than -36 dBm / MHz, and the third power is equal to -36 dBm / MHz.

[0056] In some embodiments, the output power when the NCR-Fwd is in the second or third state is defined as follows: that, during the period it is in the second or third state, it does not exceed / below / below the average power measured within a certain time period. For example, during the period it is in the second or third state, it does not exceed / below / below the average power measured within a certain time period, filtered by a filter (e.g., a square filter) whose bandwidth is equal to the passband bandwidth of the NCR-Fwd and centered on the assigned channel frequency. The time period is, for example, related to the SCS, for example, time period = 70 / Nμs, N = SCS / 15. The SCS is, for example, the SCS of the transmitted signal (not the signal being transmitted), but is not limited to this.

[0057] In some embodiments, the transfer unit supports a direct transition (or switch) from the third state to the first state. Alternatively, the transfer unit does not support a direct transition from the third state to the first state and / or from the first state to the third state; in other words, when NCR-Fwd is in the third state, it can always transition first to the second state and then from the second state to the first state. Similarly, the transfer unit may or may not support a direct transition from the first state to the third state.

[0058] In some embodiments, only the transition time (or switching time) between the first state and the second state is defined, or only the transition time between the first state and the third state is defined, for example, the first transition time described below. In other words, the first transition time is included only when switching between the first state and the second state, and not when switching between the first state and the third state, or the first transition time is included only when switching between the first state and the third state, and not when switching between the first state and the second state.

[0059] In some embodiments, the transition time between the first and second states and the transition time between the first and third states are defined; in other words, the transition time is included when switching between the first and second states, and also when switching between the first and third states. Furthermore, the transition time between the second and third states may or may not be defined.

[0060] In some embodiments, the transition time between the first and second states is the same as the transition time between the first and third states, for example, the first transition time.

[0061] In some embodiments, the transient period between the first and second states is different from the transient period between the first and third states. For example, the transient period between the first and second states is the first transient period, and the transient period between the first and third states is the second transient period, with the first transient period being shorter than the second transient period. For example, the transient period is equal to 10 μs and the transient period is greater than 10 μs, or the transient period is less than 10 μs and the transient period is equal to 10 μs. Alternatively, for example, the transient period is equal to 3 μs and the transient period is greater than 3 μs, or the transient period is less than 3 μs and the transient period is equal to 3 μs.

[0062] In some embodiments, transition times may be defined for different working frequency bands or frequency ranges (e.g., FR1, FR2, FR2-1, FR2-2), or in other words, the first and / or second transition times described above are defined for NCR-Fwd working in different frequency bands or frequency ranges. For example, for FR1, the first transition time is equal to 10 μs and the second transition time is greater than 10 μs, or the first transition time is less than 10 μs and the second transition time is equal to 10 μs. For FR2, the first transition time is equal to 3 μs and the second transition time is greater than 3 μs, or the first transition time is less than 3 μs and the second transition time is equal to 3 μs.

[0063] Figure 3 shows the transition time and output power for each state in an embodiment of the present invention (assuming that the requirements for transition time and output power are all different). As shown in Figure 3, the switch from the second state to the first state (also called a change) includes the first transition time, the switch from the first state to the third state includes the second transition time, the output power of NCR-Fwd is greater than the first power under the first state, the output power of NCR-Fwd is less than the second power under the second state, and the output power of NCR-Fwd is less than the third power under the third state. First power > second power > third power, and the values ​​of the three are different. Note that Figure 3 is merely an example, and for example, the second power and third power may be the same, the first transition time and second transition time may be the same, or the state change may not include the first and second transition times, and a comprehensive enumeration is omitted here.

[0064] The above describes the actions of the transfer unit under different states; the following describes the actions of the mobile terminal when the transfer unit is in a different state.

[0065] In some embodiments, the transfer unit is in a third state during period D, and the mobile terminal (NCR-MT) does not receive some or all of the downlink signals and / or transmit some or all of the uplink signals during period D. For example, the downlink signals include second control information for instructing the transfer unit to transfer the signals, and the second control information includes RRC, MAC CE, or DCI.

[0066] In some embodiments, the transfer unit is in a third state during period D, and the mobile terminal does not monitor the DCI format for instructing the transfer unit to transfer a signal during period D, or does not expect to receive second control information (e.g., DCI) for instructing the transfer unit to transfer a signal during period, or does not expect to receive second control information (e.g., RRC or MAC CE or DCI) for instructing the transfer unit to transfer a signal during period.

[0067] Alternatively, the transfer unit is in a second or third state during period D, and the mobile terminal monitors a DCI format for instructing the transfer unit to transfer a signal during that period, or the mobile terminal receives second control information instructing the transfer unit to transfer a signal during that period, or the mobile terminal receives second control information instructing the transfer unit to transfer a signal during that period after receiving the first control information.

[0068] In some embodiments, the first state, second state, and third state refer to the state of the mobile terminal (NCR-MT) of the transporter, and the above-mentioned first state, second state, or third state is used to represent the working state or open / closed state of the NCR-MT.

[0069] In some embodiments, the third state represents the inability of the NCR-MT to transmit or receive signals on the C-link, for example, under the third state, the mobile terminal (NCR-MT) does not receive some or all of the downlink signals and / or transmit some or all of the uplink signals during period D. For example, the downlink signals include second control information for instructing the transfer unit to transfer the signals, and the second control information includes RRC, MAC CE, or DCI.

[0070] In some embodiments, the third state represents that the NCR-MT does not monitor or expect to monitor the transmission or reception of signals over C-link, for example, under the third state, the mobile terminal does not monitor the DCI format for instructing the transfer unit to transfer a signal during the period D, or does not expect to receive any second control information (e.g., DCI) instructing the transfer unit to transfer a signal during the period, or does not expect to receive any second control information (e.g., RRC or MAC CE or DCI) instructing the transfer unit to transfer a signal during the period.

[0071] Alternatively, the second or third state represents monitoring a signal transmitted or received by the NCR-MT via C-link or transmitting or receiving a signal via C-link, for example, under the second or third state, the mobile terminal monitors a DCI format for instructing the transfer unit to transfer a signal during the period, or the mobile terminal receives second control information instructing the transfer unit to transfer a signal during the period, or the mobile terminal receives second control information instructing the transfer unit to transfer a signal during the period after receiving the first control information.

[0072] In some embodiments, the periods corresponding to the above-mentioned first, second, or third states are represented by a time-domain resource in the network equipment configuration, that is, the mobile terminal of the transceiver receives first control information for network equipment transmission, the first control information may include DCI and / or RRC signaling and / or MAC CE, the first control information includes at least first information for indicating a time-domain resource (period), and the first information can explicitly or implicitly indicate that the transceiver unit is in the first, second, or third state in the time-domain resource, so that the transceiver unit is in the first, second, or third state in the time-domain resource indicated by the first information.

[0073] The following explains how to direct time-domain resources based on primary information.

[0074] In some embodiments, the first information may be carried by one or more first information fields, which indicate the starting position (offset) and / or duration and / or interval and / or period of the time-domain resource. The time-domain resource is periodic, semi-persistent, or aperiodic. The aforementioned starting position (offset) and / or duration and / or interval and / or period can indicate time units as granularity, such as subframes, slots, symbols, mini-slots, milliseconds, etc.

[0075] In some embodiments, the first information area may include the number of time units included in the starting position (shift) and / or time length and / or interval and / or period of the time domain resource (for example, field_1 and / or field_2 in Element_2 in the example described below), and the number of time units indicates the starting position (shift) and / or time length and / or interval and / or period of the time domain resource; or the first information area may include an index of time units (for example, field_3 in Element_2 in the example described below); or the first information area (for example, the time domain resource allocation information area described below) may include a single row index value, and the index value and the time domain resource allocation table indicate the starting position (shift) and / or time length and / or interval and / or period.

[0076] In some embodiments, when carried by multiple (X) first information fields, the information about time-domain resources indicated by different first information fields may differ. For example, each of the different first information fields may indicate different information such as shift, time length, or period (for example, field_1, field_2, and field_3 in Element_2 in the example described later), or the different first information fields may indicate different time units, for example, each of the different first information fields may indicate a slot, a symbol, etc., or the time-domain resources indicated by the different first information fields may not overlap or may partially overlap. Embodiments of the present invention are not limited to these.

[0077] In some embodiments, when carried by multiple (X) first information fields, the X first information fields may be divided into multiple (Y) sets of first information fields, each set containing one or more (Z) first information fields, where one set of first information fields points to a subset of time-domain resources, and the time-domain resources pointed to by different sets of information fields do not overlap or partially overlap. For example, in Example 6 described later, Element_2 contains one set of first information fields, which include three first information fields: field_1, field_2, and field_3.

[0078] In some embodiments, the first control information may or may not include second information for directing one or more access link beams. Whether the first control information includes the second information depends on the setting of the working frequency bandwidth (or frequency range) and / or capability and / or higher-layer parameters of the transfer unit.

[0079] For example, being related to the working frequency band (or frequency range) means that when the working frequency band of the transfer unit is in FR1, the first control information does not include the second information, and when the working frequency band of the transfer unit is in FR2, the first control information includes the second information.

[0080] For example, capability-related means that when the transporter's access link beam is fixed (or only one access link beam (analog beam) is supported), the first control information includes the second information. When the transporter's access link beam is adjustable or switchable (or the transporter supports multiple access link beams), the first control information includes the second information. In this example, the transporter may or may not transmit capability-related information to network equipment. This capability-related information includes, for example, the number of access link beams supported by the transporter, and / or beam index, and / or spatial characteristics-related information. The beam index will be discussed later.

[0081] For example, when the working frequency band of a transceiver is in FR1, it is assumed that the access link beam is fixed (or that only one access link beam (analog beam) is supported), and the transceiver does not need to transmit the capability-related information to the network equipment. Alternatively, when the transceiver's access link beam is adjustable / switchable (or the transceiver supports multiple access link beams), it transmits the capability-related information to the network equipment, but otherwise the network equipment does not need to transmit the capability-related information.

[0082] For example, when the working frequency band of the transceiver is in FR2, it is assumed that the access link beam is adjustable / switchable (or the transceiver supports multiple access link beams), and the transceiver does not need to transmit such capability-related information to network equipment, or when the transceiver's access link beam is fixed (or only one access link beam (analog beam) is supported), it transmits such capability-related information to network equipment, but otherwise it does not need to transmit such capability-related information to the base station.

[0083] Furthermore, for example, when the working frequency band of the transceiver is in FR1 or FR2, the transceiver transmits capability-related information to network equipment regardless of whether the access link beam is fixed or adjustable / switchable (or the transceiver supports multiple access link beams), for example, when the access link beam is fixed, the number of access link beams reported is 1, or when the access link beam is adjustable / switchable (or the transceiver supports multiple (N) access link beams), the number of access link beams reported is N.

[0084] For example, being related to the setting of a higher-layer parameter (which is temporally prior to the first control information) means the following: for example, the first control information is DCI (DCI format X_Y), the higher-layer parameter is one information field of RRC signaling, and the information field is used (directly or indirectly) to determine whether DCI format X_Y contains the second information. For example, the higher-layer parameter may be 1 bit, and when the setting of the higher-layer parameter contains the second information (for example, the bit value is 1), DCI format X_Y contains the second information, and when the setting of the higher-layer parameter does not contain the second information (for example, the bit value is 0), DCI format X_Y does not contain the second information. Also, for example, if the information field is contained in a certain information element IE or another information field, DCI format X_Y contains the second information, and otherwise does not contain the second information. Furthermore, for example, the upper-layer parameters are used to set the beams that can be indicated by the access link beams that can be indicated by the DCI format X_Y (also called candidate beams). When one access link beam of the transporter is set as a candidate beam, the DCI format X_Y does not include the second information. When multiple access link beams are set as candidate beams, the DCI format X_Y includes the second information.

[0085] For example, the upper-level parameters exampleField_4 and exampleField_5 can be represented in ASN.1 data format as follows:

[0086] [Table 1] Among these, exampleField_4 is used to set an information field for indicating an access link beam in DCI format X_Y, where INTEGER(0..3) may be the number of bits in the information field, and optionally may include Element_3, which is used to set a list of beam patterns corresponding to the information field (assuming the information field indicates an index for one beam pattern). exampleField_4 may or may not exist; that is, exampleField_4 exists conditionally, and the condition XYZ1 includes the following: for FR2 (or FR2-1), optional present and for FR1, absent; or for FR2 (or FR2-1), mandatory present and for FR1, absent; or for FR2 (or FR2-1), mandatory present and for FR1, optional present.

[0087] Of these, exampleField_5 is used to set an information field for specifying time-domain resources in DCI format X_Y, and Element_4 sets the time-domain resource list corresponding to that information field, for example, PDSCH-TimeDomainResourceAllocationList.

[0088] For example, the upper-level parameter ExampleIE_6 or exampleField_6 can be represented in ASN.1 data format as follows:

[0089] [Table 2] Of these, ExampleIE_6 or exampleField_6 is used to set DCI format X_Y, aField is used to set an information area for indicating an access link beam in DCI format X_Y, INTEGER(0..3) may be the number of bits in the information area, and optionally may include Element_3, which is used to set a list of beam patterns corresponding to the information area (assuming the information area indication indicates an index of one beam pattern), and embodiments of the present invention are not limited to these. aField may or may not exist, i.e., aField exists conditionally, and the condition XYZ1 is as described above, and a detailed explanation is omitted here. anotherField is used to set an information area for indicating a time-domain resource in DCI format X_Y, and Element_4 sets a time-domain resource list corresponding to the information area, for example, PDSCH-TimeDomainResourceAllocationList.

[0090] For example, the second piece of information may be related information for one or more access link beams, and such related information may include beam types and / or beam indices. Beam types and indices will be described later.

[0091] In some embodiments, the first control information may or may not include third information for indicating the first, second, or third state. For example, the third information may be 1-bit or 2-bit information, which is used to indicate that the state of the transfer unit is the first, second, or third state, for example, a bit value of 0 indicates the first state, a bit value of 1 indicates the third state, and a complete enumeration is omitted here.

[0092] In some embodiments, the first control information is DCI (DCI format X_Y), and includes the same information field corresponding to the second and third information; in other words, the same information field in DCI format X_Y provides the second or third information when different. For example, for FR1, the information field is used to provide the third information, and for FR2, the information field is used to provide the second information. Also, for example, when the NCR supports or configures only one access link beam, the information field is used to provide the third information, and when the NCR supports or configures multiple access link beams, the information field is used to provide the second information.

[0093] The following provides an illustrative explanation of the implementation method for the first control information.

[0094] In some embodiments, the first information explicitly indicates that the transfer unit is in a first, second, or third state in the time-domain resource; in other words, the first information is used solely to indicate that the transfer unit is in a first, second, or third state in the time-domain resource, and does not indicate anything else.

[0095] In this embodiment, the first control information may or may not include second information for directing one or more access link beams. For example, when the transceiver's working frequency band is in FR1, beam control or directing is not supported, and / or the access link beams are tacit, fixed, or default (only one analog beam is supported), so the network equipment does not transmit second information for directing one or more access link beams to the terminal equipment, or does not transmit second information for directing one or more access link beams in the first control information.

[0096] In the embodiments described above, the second information indicates one or more access link beams as an example, but embodiments of the present invention are not limited thereto, and the second information may further indicate one or more backhaul link beams, and the implementation method is the same, and a detailed explanation of this is omitted in embodiments of the present invention.

[0097] In this embodiment, the first control information may further include third information for indicating a first state, a second state, or a third state.

[0098] For example, the first control information includes the first information but not the second information, and optionally includes a third information, in which case the access link beam may be tacit, fixed, or default, and the first information indicates only that the transfer unit is in the first, second, or third state in the time-domain resource.

[0099] In some embodiments, the first information implicitly indicates that the transfer unit is in a first, second, or third state in the time-domain resource, and the first information is further used to indicate a time-domain resource corresponding to one or more access link beams and / or one or more backhaul link beams. The one or more access link beams and / or one or more backhaul link beams are indicated by the second information contained in the second control information. For example, when the working frequency band of the transferr is in FR2, the network equipment transmits the second information to the terminal equipment to indicate one or more access link beams, since the transferr supports beam tuning, indication, or switching (or the transferr supports multiple (N) access link beams).

[0100] For example, the first control information includes first information and second information, the second information indicating one or more access link beams and / or one or more backhaul link beams, the first information indicating a time-domain resource corresponding to one or more access link beams and / or one or more backhaul link beams, and the first information can further implicitly indicate that the state of the transfer unit in the time-domain resource is the first, second, or third state.

[0101] The following is an example to illustrate this point.

[0102] The following explains how to define the index for the access (AC) link beam.

[0103] The AC link beam may also be called the terminal equipment side beam, and it refers to the receive beam / transmit beam used by the transceiver in the AC link. The transmit beam transfers signals from network equipment to terminal equipment, and the receive beam transfers signals from terminal equipment to network equipment. The backhaul link beam may also be called the network equipment side beam, and it refers to the receive beam / transmit beam used by the transceiver in the BH link. The receive beam transfers signals from terminal equipment to network equipment, and the transmit beam transfers signals from network equipment to terminal equipment. Of these, the (antenna) beam refers, for example, to the main lobe of the radiation pattern of an antenna array.

[0104] In some embodiments, the transporter can support multiple beams (or antenna beams) of different directions and / or widths, and associations may exist between the beams. For example, an association between a first beam and a second beam may include the following: the beam center directions of the first and second beams are the same, and / or the beam peak directions of the first and second beams are the same, and / or the first and second beams are QCL (e.g., QCL type D), and / or the first beam is within the range of the second beam, and / or the second beam is within the range of the first beam, and / or the beam width of the first beam is within the beam width range of the second beam, and / or the beam width of the second beam is within the beam width range of the first beam. Of these, the beam center direction refers, for example, to the geometric center of the beam's half power contour, and the beam peak direction refers, for example, to the direction where the beam's maximum EIRP is located.

[0105] Example 1: The beams supported by the NCR are numbered sequentially, and this numbering can be done according to spatial relationships. For example, adjacent beams that are numbered together are adjacent in space. For example, if the NCR supports four beams and they are numbered from 0 or 1, their respective indices will be 0-3 or 1-4.

[0106] Example 2: The NCR supports a first beam (broad beam) and a second beam (narrow beam) simultaneously, and the beams are sequentially numbered according to their spatial relationships. For example, the broad beam is numbered first, then the narrow beam is numbered, and adjacently numbered broad beams are adjacent in space, and adjacently numbered narrow beams are adjacent in space. Alternatively, one broad beam and the narrow beam associated with it are numbered first, and then the other broad and narrow beams are numbered in the same manner. For example, Figure 4A shows a beam index in an embodiment of the present invention. As shown in Figure 4A, the NCR supports two broad beams (first beam) and eight narrow beams (second beam), with the first four narrow beams associated with the first broad beam and the latter four narrow beams associated with the second broad beam. If all beams are numbered from 0 or 1, for example, 0 to 9 (or 1 to 10, not shown). When numbering, the first two beams may be wide beams and the rest narrow beams, or the first and sixth beams may be wide beams and the others narrow beams.

[0107] Example 3: The NCR simultaneously supports a first beam (broad beam) and a second beam (narrow beam), and the first and second beams are sequentially numbered, with the numbering being done according to spatial relationships. Adjacent wide beams numbered are adjacent in space, and adjacent narrow beams numbered are adjacent in space. For example, Figure 4B shows a beam index in an embodiment of the present invention. As shown in Figure 4B, the NCR supports two wide beams (first beam) and eight narrow beams (second beam). If the wide beams and narrow beams are numbered from 0 or 1, for example, the wide beams would be 0-1 (or 1-2, not shown) and the narrow beams would be 0-7 (or 1-8, not shown). For example, the first four narrow beams are associated with the first wide beam, and the last four narrow beams are associated with the second wide beam.

[0108] Example 4: The NCR simultaneously supports a first beam (broad beam) and a second beam (narrow beam), and the first and second beams are numbered according to their layer class, starting from 0 or 1, and this numbering can be done according to spatial relationships. Adjacent broad beams that are numbered are adjacent in space, and adjacent narrow beams that are numbered are adjacent in space. For adjacent broad beams that are numbered, among the narrow beams associated with a broad beam with a relatively small sequential number, those with a relatively large sequential number are spatially adjacent, and among the narrow beams associated with a broad beam with a relatively large sequential number, those with a relatively small sequential number are spatially adjacent. For example, Figure 4C is a diagram showing the beam index in an embodiment of the present invention. As shown in Figure 4C, the NCR supports two broad beams (first beam) and eight narrow beams (second beam). The sequential numbers for the broad beams are 0 to 1 (or 1 to 2, not shown), and the four narrow beams associated with the first broad beam and the four narrow beams associated with the second broad beam are sequential numbers 0 to 3 or (or 1 to 4, not shown).

[0109] Although the above examples of indices are all one-dimensional, the embodiments of the present invention are not limited to these, and the index may be two-dimensional or three-dimensional. For example, beams may be arranged according to a two-dimensional array, and horizontal and vertical beams may be numbered separately; in this case, the index is a two-dimensional index. A comprehensive list is omitted here.

[0110] In some embodiments, the beam range corresponding to a numberable beam may be all beams that can be used for NCR transmission or all beams that can be indicated by the first control information (candidate beams set by the higher-layer parameters of the network equipment) and / or all beams supported by the NCR, or one beam may correspond to one or more beam indices (each of which is predefined and / or reported to the network equipment by the NCR and / or set by the network equipment). For example, one beam may correspond to a first index and a second index, where the first index is an index that uniquely identifies the beam among all beams supported by the NCR, and the second index is an index that uniquely identifies the beam among all beams that can be used for NCR transmission or all beams that can be indicated by the first control information (candidate beams set by the higher-layer parameters of the network equipment).

[0111] In the example described above, the first control information includes the first information and the second information, the one or more access link beams indicated by the second information correspond to the time-domain resources indicated by the first information, and when the second information indicates multiple access link beams, the multiple access link beams are time-division or frequency-division.

[0112] In some embodiments, the first information is carried by one first information field, the time-domain resource indicated by the first information field corresponds to one access link beam, and the second information is carried by one or more second information fields, the one or more second information fields indicate one access link beam, and the time-domain resource indicated by the one first information field corresponds to one.

[0113] Example (1): When carried by multiple (M) second information fields, the beam-related information indicated by different second information fields will be different. For example, when two second information fields are included, one may be used to indicate the beam type (broad beam / narrow beam) and the other to indicate the beam index (of the beam of that beam type), or one may be used to indicate the marker of a beam set and the other to indicate the beam index (of the beam of that beam set), or one may be used to indicate the index of a broad beam and the other to indicate the index of a narrow beam (for example, according to Example 3 above regarding indices, each may reserve a specific value to indicate that it does not indicate a broad beam or a narrow beam, for example, according to Example 4 above regarding indices, the second information field for indicating only the index of a narrow beam may reserve a specific value to indicate that it does not indicate a narrow beam (or that the DCI indicates a broad beam)).

[0114] Example (2): When a second information field is included, the second information field directly or indirectly indicates the beam index (first index or second index) of an access link beam. When directly indicating, the decimal value of the second information field is equal to the beam index value, thereby indicating the corresponding beam. When indirectly indicating, the decimal / binary value of the second information field is mapped to the beam index values ​​from smallest to largest in order from smallest to largest, thereby indicating the corresponding beam. Alternatively, the bits in the second information field are mapped to the beam index values ​​from smallest to largest in order from MSB to LSB (or vice versa), where a bit value of 0 indicates that the corresponding beam is not indicated, and a bit value of 1 indicates that the corresponding beam is indicated (only one bit is 1 and the others are 0). For example, in Example 1 above, the second information field may be 0001, indicating the last numbered beam.

[0115] In some embodiments, the first information is carried by one first information area, the time-domain resource indicated by the first information area corresponds to one or more access link beams, and the second information is carried by one or more second information areas, the one or more second information areas indicate one or more access link beams, and correspond to the time-domain resource indicated by the one first information area.

[0116] Example (3): When the second information is carried by multiple (K) second information fields, each second information field points to one access link beam, and the access link beams pointed to by the multiple second information fields correspond to different parts of the time-domain resource pointed to by the first information field (time-division), or all of the access link beams pointed to by the multiple second information fields correspond to all of the time-domain resource pointed to by the first information field (frequency-division), or are a mixture of time-domain resources.

[0117] Example (4): When secondary information is carried by multiple (K) secondary information fields, the K secondary information fields can be divided into multiple (N) sets of secondary information fields, each set containing one or more (M) secondary information fields, each set of secondary information fields indicating one access link beam, and the access link beams indicated by multiple sets of secondary information fields correspond to different parts of the time-domain resource indicated by the primary information field (time-division), or all of the access link beams indicated by multiple sets of secondary information fields correspond to all of the time-domain resource indicated by the primary information field (frequency-division), or are a mixture of time-domain resources. When one set of secondary information fields contains M secondary information fields, the beam-related information indicated by different secondary information fields is different. The specific indication method is as described in Example (1) above, and a detailed explanation is omitted here.

[0118] In some embodiments, the first information is carried by multiple first information fields, and the time-domain resources indicated by these fields correspond to one or more access link beams. For example, the information about time-domain resources indicated by different first information fields is different. For example, the first information is carried by two first information fields, and the time units indicated by the different first information fields are different, one used to indicate a slot and the other to indicate a symbol, or the information indicated by the different first information fields is different, one used to indicate a starting position and the other to indicate a duration. Alternatively, for example, the first information is carried by three first information fields, each used to indicate a slot shift, a symbol shift, and a duration. Or, for example, the time-domain resources indicated by different first information fields do not overlap or partially overlap. The time-domain resources indicated by these multiple first information fields are a union of the time-domain resources indicated by these multiple first information fields.

[0119] Example (5): The first information is carried by multiple first information fields, the second information is carried by one or more second information fields, and the one or more second information fields indicate one access link beam, corresponding to the time-domain resources indicated by the multiple first information fields. When the second information is carried by one second information field, the one second information field directly or indirectly indicates the one access link beam; the specific indication method can be found in Example (2) above, and a detailed explanation is omitted here. When the second information is carried by multiple second information fields, the beam information (beam-related information) indicated by different second information fields will be different. The specific indication method can be found in Example (1) above, and a detailed explanation is omitted here.

[0120] Example (6): The first information is carried by multiple first information fields, the second information is carried by one or more second information fields, the one or more second information fields point to one or more access link beams, and these correspond to the time-domain resources pointed to by the multiple first information fields. Example 1: When the second information is carried by multiple (K) second information fields, each second information field points to one access link beam, and each first information field and each second information field have a one-to-one correspondence, i.e., the access link beam pointed to by one second information field is applied to the time-domain resource pointed to by its corresponding first information field. Example 2: When secondary information is carried by multiple (K) secondary information fields, the K secondary information fields can be divided into multiple (N) sets of secondary information fields, each set of secondary information fields contains one or more (M) secondary information fields, each set of secondary information fields points to one access link beam, each primary information field and each set of secondary information fields have a one-to-one correspondence, and the access link beam pointed to by a set of secondary information fields is applied to the time-domain resource pointed to by its corresponding primary information field. When a set of secondary information fields contains M secondary information fields, the beam-related information pointed to by different secondary information fields will be different. The specific pointing method is as described in Example (1) above, and a detailed explanation is omitted here.

[0121] In some embodiments, the first control information may be RRC signaling.

[0122] In some embodiments, when the first control information is an RRC signaling, the same information element (ExampleIE_1 in the example) or the same field (exampleField_1 in the example) in the RRC signaling may be used to set up an access link beam or to set the transfer unit to be in a first, second, or third state, respectively.

[0123] Example 1: ExampleIE_1 or exampleField_1 can be represented in ASN.1 data format as follows:

[0124] [Table 3] Of these, aField is used to set the access link beam, and INTEGER(0..9) may be the beam index (corresponding to the second information), the number of beams, etc., and may optionally include Element_X, which is used to set the beam pattern. However, the embodiments of the present invention are not limited to these. The aField may or may not exist (the first control information may or may not include the second information), that is, aField exists conditionally, and the condition XYZ1 includes the following, that is, for FR2 (or FR2-1), aField is optionally present and for FR1, aField is not present; or for FR2 (or FR2-1), aField is always present and for FR1, aField is not present; or for FR2 (or FR2-1), aField is always present and for FR1, aField is optionally present.

[0125] If aField exists, anotherField is used to set the time-domain resource corresponding to the access link beam (set by the corresponding aField), thereby implicitly indicating that the NCR-Fwd is in the first state of that time-domain resource. If aField does not exist, anotherField is used to indicate a time-domain resource in which the transfer unit is in the first, second, or third state. Element_2 contains primary information for indicating a time-domain resource, and Element_2 contains one or more primary information fields.

[0126] Example 2: ExampleIE_1 or exampleField_1 can be represented in ASN.1 data format as follows: ExampleIE_1 or exampleField_1 is used to set up an access link beam, or to set a transfer unit to be in the first, second, or third state.

[0127] [Table 4] Of these, Element_1 is used to configure one or more access link beams and the time-domain resources corresponding to these beams, or to configure time-domain resources in which the transfer unit is in the first, second, or third state.

[0128] Of these, aField is used to set the access link beam, and INTEGER(0..9) may be the beam index (corresponding to the second information), the number of beams, etc., and may optionally include Element_X, which is used to set the beam pattern. However, the embodiments of the present invention are not limited to these. The aField may or may not exist (the first control information may or may not include the second information), that is, aField exists conditionally, and the condition XYZ1 includes the following, that is, for FR2 (or FR2-1), aField is optionally present and for FR1, aField is not present; or for FR2 (or FR2-1), aField is always present and for FR1, aField is not present; or for FR2 (or FR2-1), aField is always present and for FR1, aField is optionally present.

[0129] If aField exists, anotherField is used to set the time-domain resource corresponding to the access link beam (set by the corresponding aField), thereby implicitly indicating that the NCR-Fwd is in the first state of that time-domain resource. If aField does not exist, anotherField is used to set the time-domain resource in which the transfer unit is in the first, second, or third state. Element_2 contains primary information for indicating the time-domain resource, and Element_2 contains one or more primary information fields.

[0130] Example 3: ExampleIE_1 or exampleField_1 can be represented in ASN.1 data format as follows: ExampleIE_1 or exampleField_1 is used to set up an access link beam, or to set a transfer unit to be in the first, second, or third state.

[0131] [Table 5] Of these, Element_1 is used to configure one or more access link beams and the time-domain resources corresponding to these beams, or to configure time-domain resources in which the transfer unit is in the first, second, or third state.

[0132] Of these, aField is used to set the access link beam, and INTEGER(0..9) may be the beam index (corresponding to the second information), the number of beams, etc., and may optionally include Element_X, which is used to set the beam pattern. However, the embodiments of the present invention are not limited to these. The aField may or may not exist (the first control information may or may not include the second information), that is, aField exists conditionally, and the condition XYZ1 includes the following, that is, for FR2 (or FR2-1), aField is optionally present and for FR1, aField is not present; or for FR2 (or FR2-1), aField is always present and for FR1, aField is not present; or for FR2 (or FR2-1), aField is always present and for FR1, aField is optionally present.

[0133] If aField exists, anotherField is used to set the time-domain resource corresponding to the access link beam (set by the corresponding aField), thereby implicitly indicating that the NCR-Fwd is in the first state of that time-domain resource. If aField does not exist, anotherField is used to set the time-domain resource in which the transfer unit is in the first, second, or third state. Element_2 contains primary information for indicating the time-domain resource, and Element_2 contains one or more primary information fields.

[0134] In some embodiments, when the first control information is RRC signaling, different information elements or different domains in the RRC signaling are used to set up an access link beam or to set the transfer unit to be in a first, second, or third state, and different information elements (ExampleIE_2 and ExampleIE_3 in the example) or different domains (exampleField_2 and exampleField_3 in the example) share the same information element (Element_1 or Element_2 in the example) to set up a time-domain resource. Example 4: ExampleIE_2 or exampleField_2, and ExampleIE_3 or exampleField_3 can be represented in ASN.1 data format as follows:

[0135] [Table 6] Of these, ExampleIE_2 or exampleField_2 is used to set the access link beam, and ExampleIE_3 or exampleField_3 is used to set the transfer unit to be in the first, second, or third state. ExampleIE_2 or exampleField_2 may or may not exist (the first control information may or may not include the second information), that is, it exists conditionally, and the condition XYZ1 includes the following: for FR2 (or FR2-1), it is optionally present and for FR1, it is absent; or for FR2 (or FR2-1), it is always present and for FR1, it is absent; or for FR2 (or FR2-1), it is always present and for FR1, it is optional present.

[0136] Example 5: ExampleIE_2 or exampleField_2, and ExampleIE_3 or exampleField_3 can be represented in ASN.1 data format as follows:

[0137] [Table 7] Of these, ExampleIE_2 or exampleField_2 is used to set the access link beam, and ExampleIE_3 or exampleField_3 is used to set whether the transfer unit is in the first, second, or third state. The ExampleIE_2 or exampleField_2 (corresponding to the second information) may or may not exist (the first control information may or may not include the second information), that is, it exists conditionally, and the condition XYZ1 includes the following: for FR2 (or FR2-1), it is optionally present and for FR1, it is absent; or for FR2 (or FR2-1), it is always present and for FR1, it is absent; or for FR2 (or FR2-1), it is always present and for FR1, it is optionally present. For an explanation of Element_1, please refer to Example 6, and a detailed explanation is omitted here.

[0138] Example 6: ExampleIE_2 or exampleField_2, and ExampleIE_3 or exampleField_3 can be represented in ASN.1 data format as follows:

[0139] [Table 8] Of these, ExampleIE_2 or exampleField_2 is used to set the access link beam (corresponding to the second information), and ExampleIE_3 or exampleField_3 is used to set the transfer unit to be in the first, second, or third state. ExampleIE_2 or exampleField_2 may or may not exist (the first control information may or may not include the second information), that is, it exists conditionally, and the condition XYZ1 includes the following: for FR2 (or FR2-1), it is optionally present and for FR1, it is absent; or for FR2 (or FR2-1), it is always present and for FR1, it is absent; or for FR2 (or FR2-1), it is always present and for FR1, it is optionally present.

[0140] Of these, Element_1 is used to configure one or more access link beams and the time-domain resources corresponding to these beams, or to configure time-domain resources in which the transfer unit is in the first, second, or third state.

[0141] Of these, aField is used to set the access link beam, and INTEGER(0..9) may be a beam index, the number of beams, etc., and optionally includes Element_X, which is used to set the beam pattern. However, the embodiments of the present invention are not limited to this. aField may or may not exist, that is, aField may exist conditionally, and the condition XYZ2 may include the following, namely, for ExampleIE_2 or exampleField_2 it is always present, and for ExampleIE_3 or exampleField_3 it is not present.

[0142] If aField exists, anotherField is used to set the time-domain resource corresponding to the access link beam (set by the corresponding aField), thereby implicitly indicating that the NCR-Fwd is in the first state of that time-domain resource. If aField does not exist, anotherField is used to set the time-domain resource in which the transfer unit is in the first, second, or third state. Element_2 contains primary information for indicating the time-domain resource, and Element_2 contains one or more primary information fields.

[0143] Of these, Element_2 can be represented in ASN.1 data format as follows:

[0144] [Table 9] Of these, field_1 is used to set the period and / or offset of the time-domain resource, field_2 is used to set the duration within the period, and field_3 is used to set the slots and / or symbols within the duration, for example, to specify the slot index, starting slot index, starting symbol index, number of slots, and number of symbols. Of these, the slot index is an index within 10ms (one frame) or 1ms (one subframe), and the symbol index is an index within 10ms (one frame), 1ms (one subframe), or one slot. The number of slots is the number of slots within the duration. The number of symbols is the number of symbols within the duration or slot.

[0145] In some embodiments, the first control information may be DCI, and the DCI may be in DCI format X_Y, for example, the DCI format X_Y may be an existing DCI format (e.g., DCI format 1_0 / 1_1 / 1_2 / 0_0 / 0_1 / 0_2 / 2_2, etc.), or it may be a DCI format newly introduced for NCR.

[0146] In some embodiments, the DCI may be unicast / dedicated or group common.

[0147] In some embodiments, the DCI's CRC is scrambled by a first radio network temporary identifier (RNTI) or by a second RNTI, the first RNTI including, for example, RNTI types that can be adopted by non-NCRs / RNTI types that can also be set by non-NCRs, such as first C-RNTI, first MCS-C-RNTI, and SFI-RNTI, and the second RNTI including, for example, RNTIs exclusive to NCRs (e.g., NCR-RNTI or second C-RNTI, second MCS-C-RNTI), in other words, non-NCRs cannot adopt / cannot set the second RNTI.

[0148] In some embodiments, NCR (e.g., NCR-MT) can be set in a dedicated search space USS and / or a common search space CSS to monitor DCI format X_Y. For example, if DCI format X_Y is unicast or dedicated, it can be set in USS to monitor the DCI format, and accordingly the RNTI for scrambling the CRC is, for example, the first C-RNTI, or NCR-RNTI, or the second C-RNTI, or the second MCS-C-RNTI. If DCI format X_Y is group common, it can be set in CSS to monitor the DCI format, and CSS is, for example, the Type3-PDCCH CSS set, and accordingly the RNTI for scrambling the CRC is, for example, SFI-RNTI, or NCR-RNTI, or the second C-RNTI, or the second MCS-C-RNTI.

[0149] For example, the DCI includes one or more first information areas, each of which includes a time-domain resource allocation information area. One TDRA information area indicates one row of TDRA settings by row index. A time-domain resource allocation (TDRA) table (or TDRA table) includes at least one row, and for convenience, each row will be referred to as one TDRA setting; that is, a TDRA table includes at least one TDRA setting. One TDRA setting includes at least one time-domain resource setting, which includes at least a symbol position (start position symbol + length) setting in a slot, and optionally, one TDRA setting may further include at least one slot shift K0 setting, and one TDRA setting may or may not include other information (e.g., mapping type). However, embodiments of the present invention are not limited thereto. Among these, the symbol position setting in the slot includes, for example, a start and length indicator SLIV, which corresponds to a valid combination of a start symbol (S) and a length (L), or it corresponds to, for example, a starting symbol setting and a length setting, and the starting symbol setting and length setting are a valid combination.

[0150] In some embodiments, the first time position relating to the first control information may be the slot, the last slot, or the last symbol where the time-domain resource or physical channel (PDCCH / PDSCH) carrying the first control information is located, or the first time position may be the subframe, slot, the last slot, or the last symbol where the HARQ-ACK information corresponding to the first control information or the physical channel (PDCCH / PDSCH) carrying the first control information is located. For example, when the first control information is a DCI, the DCI is carried by a PDCCH, and the first time position may be the subframe, slot, the last slot, or the last symbol where the PDCCH carrying the DCI is located, or the first time position may be the subframe, slot, the last slot, or the last symbol where the HARQ-ACK feedback (located in a PUCCH / PUSCH) corresponding to the DCI or the PDCCH carrying the DCI is located. For example, the first control information is a MAC CE, which may be carried by a PDSCH, and the first time position may be a subframe or slot or the last slot or the last symbol where the HARQ-ACK feedback (where the PUCCH / PUSCH) corresponding to the PDSCH carrying the MAC CE is located.

[0151] In some embodiments, the second time position of the time-domain resource indicated by the first information may be the subframe or slot in which the time-domain resource indicated by the first information is located, or the first slot or symbol in which it is located.

[0152] In some embodiments, if the state of the transporter when receiving the first control information or the state of the transporter before the time-domain resource is indicated by the first information differs from the state of the time-domain resource indicated by the first information, the state switch requires a certain transition time. Furthermore, the time required for processing by several other transporters (e.g., beam switching) and / or the time required to receive the first control information (decoding) may also be included. Therefore, the first interval between the first time position and the second time position of the time-domain resource indicated by the first information is not greater than or less than a first predetermined value or a second predetermined value. The first predetermined value is greater than the second predetermined value. Below, we will first explain using the transition from the third state or the second state to the first state as an example.

[0153] In some embodiments, the transfer unit is in a third state when the mobile terminal receives the first control information, or the transfer unit is in a third state before the time domain resource indicated by the first information, and is in a first state at the time domain resource indicated by the first information, and the first interval is not greater than or less than the first predetermined value.

[0154] For example, the first predetermined value includes the time required to switch the transfer unit from the third state to the first state, and of that time, the time required to switch from the third state to the first state may or may not include the time required for beam switching. For example, when the first control information includes the second information, the time required to switch from the third state to the first state includes the time required for beam switching, and when the first control information does not include the second information, the time required to switch from the third state to the first state does not include the time required for beam switching. Optionally, the first predetermined value may or may not include the time required for the mobile terminal to receive the first control information.

[0155] Alternatively, for example, the first predetermined value may include the time required for the transfer unit to switch from the third state to the second state, and optionally, the first predetermined value may or may not include the time required for the mobile terminal to receive the first control information.

[0156] Alternatively, for example, the first predetermined value includes the time required to switch the transfer unit from the third state to the second state and the time required to switch from the second state to the first state. Of this, the time required to switch from the second state to the first state may or may not include the time required for beam switching. For example, when the first control information includes the second information, the time required to switch from the second state to the first state includes the time required for beam switching, and when the first control information does not include the second information, the time required to switch from the second state to the first state does not include the time required for beam switching. Optionally, the first predetermined value may or may not include the time required for the mobile terminal to receive the first control information.

[0157] Alternatively, for example, the first predetermined value includes the time required for the transfer unit to switch from the third state to the second state and the time required for beam switching. Optionally, the first predetermined value may or may not include the time required for the mobile terminal to receive the first control information.

[0158] In some embodiments, the transfer unit is in a second state when it receives the first control information, or the transfer unit is in a second state before the time domain resource indicated by the first information, and is in a first state at the indicated time domain resource, and the first interval is not greater than or less than a second predetermined value.

[0159] For example, the second predetermined value includes the time required to switch the transfer unit from the second state to the first state, and of this time, the time required to switch from the second state to the first state may or may not include the time required for beam switching. For example, when the first control information includes the second information, the time required to switch from the second state to the first state includes the time required for beam switching, and when the first control information does not include the second information, the time required to switch from the second state to the first state does not include the time required for beam switching. Optionally, the second predetermined value may or may not include the time required for the mobile terminal to receive the first control information.

[0160] Alternatively, for example, the second predetermined value includes the time required for beam switching. Optionally, the second predetermined value may or may not include the time required for the mobile terminal to receive the first control information.

[0161] The above explanation uses the transition (also called a change) from the third or second state to the first state as an example, but the method of performing the transition of the transfer device from the first state to the third state, and from the first state to the second state, is the same. Furthermore, when the transfer device switches from the second state to the third state, or from the third state to the second state, for example, the transfer unit is in the third state when it receives the first control information, or the transfer unit is in the third state before the time domain resource indicated by the first information, and is in the second state at the indicated time domain resource, and the first interval is not greater than or less than a fifth predetermined value. For example, the fifth predetermined value includes the time required to switch from the third state to the second state, and optionally, the fifth predetermined value may or may not include the time required for the mobile terminal to receive the first control information.

[0162] The above describes the implementation method of the first interval using state switching as an example. Below, the implementation method of the first interval (hereinafter referred to as the second interval) will be described using whether the first control information includes the second information as an example.

[0163] In some embodiments, the second interval between the third time position relating to the first control information and the fourth time position of the time domain resource indicated by the first information is neither greater than nor less than a third predetermined value or a fourth predetermined value. The third predetermined value is greater than the fourth predetermined value. The third time position can refer to the first time position described above, and the fourth time position can refer to the second time position described above; a detailed explanation of these is omitted here.

[0164] In some embodiments, the first control information includes second information for indicating one or more access link beams, wherein the second interval is not greater than or less than the third predetermined value.

[0165] For example, the third predetermined value includes the time required to switch the transfer unit from the third state to the first state, of which the time required to switch from the third state to the first state includes the time required for beam switching, and optionally, the third predetermined value may or may not include the time required for the mobile terminal to receive the first control information.

[0166] Alternatively, for example, the third predetermined value includes the time required to switch the transfer unit from the third state to the second state and the time required to switch from the second state to the first state. Of these, the time required to switch from the second state to the first state includes the time required for beam switching. Optionally, the third predetermined value may or may not include the time required for the mobile terminal to receive the first control information.

[0167] Alternatively, for example, the third predetermined value includes the time required to switch the transfer unit from the third state to the second state and the time required for beam switching. Optionally, the third predetermined value may or may not include the time required for the mobile terminal to receive the first control information. Alternatively, for example, the third predetermined value includes the time required to switch the transfer unit from the second state to the first state, of which the time required to switch from the second state to the first state includes the time required for beam switching, and optionally, the third predetermined value may or may not include the time required for the mobile terminal to receive the first control information.

[0168] Alternatively, for example, the third predetermined value includes the time required for beam switching. Optionally, the third predetermined value may or may not include the time required for the mobile terminal to receive the first control information.

[0169] In some embodiments, the first control information does not include second information for indicating one or more access link beams, and the second interval is not greater than or less than the fourth predetermined value.

[0170] For example, the fourth predetermined value includes the time required to switch the transfer unit from the third state to the first state, of which the time required to switch from the third state to the first state does not include the time required for beam switching. Optionally, the fourth predetermined value may or may not include the time required for the mobile terminal to receive the first control information.

[0171] Alternatively, for example, the fourth predetermined value may include the time required to switch the transfer unit from the third state to the second state, and optionally, the fourth predetermined value may or may not include the time required for the mobile terminal to receive the first control information.

[0172] Alternatively, for example, the fourth predetermined value includes the time required to switch the transfer unit from the third state to the second state and the time required to switch from the second state to the first state. Of these, the time required to switch from the second state to the first state does not include the time required for beam switching. Optionally, the fourth predetermined value may or may not include the time required for the mobile terminal to receive the first control information.

[0173] Alternatively, for example, the fourth predetermined value includes the time required to switch the transfer unit from the second state to the first state, of which the time required to switch from the second state to the first state does not include the time required for beam switching. Optionally, the fourth predetermined value may or may not include the time required for the mobile terminal to receive the first control information.

[0174] Alternatively, for example, the fourth predetermined value includes the time required for beam switching. Optionally, the fourth predetermined value may or may not include the time required for the mobile terminal to receive the first control information.

[0175] In each of the above examples, whether each predetermined value includes the time required for the mobile terminal to receive the first control information may be determined based on whether or not there is HARQ-ACK feedback for the first control information.

[0176] For example, when providing feedback, if the first (third) time position is based on the HARQ-ACK position (e.g., the slot or the last slot or the last symbol where the HARQ-ACK information corresponding to DCI or MAC CE is located), each predetermined value does not need to include the time required to receive the first control information of the mobile terminal. However, if the first (third) time position is based on the first control information (the slot or the last slot or the last symbol where the PDCCH carrying the DCI is located), each predetermined value needs to include the time required to receive the first control information of the mobile terminal.

[0177] For example, when no feedback is provided, if the first (third) time position is based on the first control information (the slot where the PDCCH carrying the DCI is located, or the last slot, or the last symbol), each predetermined value must include the time required for the mobile terminal to receive the first control information.

[0178] The following explains how to determine whether or not to provide feedback on HARQ-ACK information.

[0179] In some embodiments, the mobile terminal of the transceiver transmits or does not transmit HARQ-ACK information corresponding to the first control information.

[0180] In some embodiments, whether the mobile terminal transmits HARQ-ACK information corresponding to the first control information depends on the capabilities of the transceiver and / or the settings of the higher-layer parameters. Alternatively, whether HARQ-ACK feedback for the first control information is supported depends on the capabilities of the transceiver and / or the settings of the higher-layer parameters. For example, the first control information may be DCI.

[0181] For example, this relates to capability. Suppose the first control information is DCI (DCI format X_Y), and the NCR reports to the base station whether it supports or does not support HARQ-ACK feedback for DCI format X_Y. If it reports that it supports it, the NCR sends corresponding HARQ-ACK information (ACK) to the base station after receiving DCI format X_Y; otherwise, the NCR does not send corresponding HARQ-ACK information (ACK) to the base station after receiving DCI format X_Y. In some cases, the NCR tacitly accepts that it does not support it, so the NCR only reports to the base station that it supports HARQ-ACK feedback for DCI format X_Y if it does, and does not need to report otherwise.

[0182] For example, this relates to the setting of upper-layer parameters. Suppose the first control information is DCI (DCI format X_Y), and the upper-layer parameter is one information field of RRC signaling, which is used (directly or indirectly) to determine whether the NCR performs HARQ-ACK feedback for DCI format X_Y. If the NCR is set to perform HARQ-ACK feedback for DCI format X_Y, it sends the corresponding HARQ-ACK information (ACK) to the base station after receiving DCI format X_Y; otherwise, the NCR does not send the corresponding HARQ-ACK information (ACK) to the base station after receiving DCI format X_Y. For example, the upper-layer parameter may be a 1-bit information element, and when the bit value is set to 1 by the upper-layer parameter (e.g., carried by RRC), HARQ-ACK feedback is sent for the first control information; and when the bit value is set to 0 by the upper-layer parameter (e.g., carried by RRC), HARQ-ACK feedback is not sent for the first control information. Generally, as mentioned above, NCR capabilities do not support HARQ-ACK feedback, therefore, the higher-level parameter should not be set to perform HARQ-ACK feedback for DCI format X_Y.

[0183] In some embodiments, the mobile terminal of the transceiver transmits HARQ-ACK information corresponding to the first control information, and the start position of the time-domain resource indicated by the first information is after (to ensure reliability) or before (to reduce delay) the end position of the time-domain resource for transmitting the HARQ-ACK information, or is the same as the end position. Among these, the time-domain position for transmitting the HARQ-ACK information may be predefined or indicated by network equipment, and the network equipment may set the start position of the time-domain resource indicated by the first information, taking into consideration delay and reliability.

[0184] In some embodiments, the mobile terminal of the transceiver transmits HARQ-ACK information corresponding to the first control information, and the location of the time-domain resource indicated by the first information is independent of the location of the time-domain resource for transmitting the HARQ-ACK information. Alternatively, the location of the time-domain resource indicated by the first information is not limited by the location of the time-domain resource for transmitting the HARQ-ACK information, or the network equipment does not need to consider the location of the time-domain resource for transmitting the HARQ-ACK information when setting the location of the time-domain resource indicated by the first information. For example, after the NCR receives the aforementioned first control information or a PDCCH / PDSCH for carrying the first control information, it transmits the corresponding HARQ-ACK information, and the first (third) time position relating to the first control information is the slot, the last slot, or the last symbol where the time-domain resource or physical channel (PDCCH / PDSCH) carrying the first control information is located. For example, when the first control information is a DCI, the DCI is carried by a PDCCH, and the first (third) time position may be the subframe, slot, the last slot, or the last symbol where the PDCCH carrying the DCI is located. Thus, there is no sequential limitation between the location of the time-domain resource transmitting the HARQ-ACK information and the location of the time-domain resource indicated by the first information in the first control information. In other words, the location of the time-domain resource indicated by the first information in the first control information is not limited by the location of the time-domain resource for transmitting the HARQ-ACK information, and vice versa.

For example, the embodiments described above may be used individually, or a combination of several of the embodiments described above may be used.

[0186] According to an embodiment of the present invention, by controlling the opening and closing of the transceiver using first control information, the time-domain resource corresponding to the open state of the transceiver is made to match the time-domain resource for data transmission between network devices and terminal devices.
