In order to reduce propagation loss of radio waves and increase transmission distance, beamforming, massive Multiple Input Multiple Output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, massive antenna techniques are discussed in 5G communication systems.

Further, in the 5G communication system, development of system network improvement is being performed based on advanced small cells, cloud Radio Access Networks (RANs), ultra dense networks, device-to-device (D2D) communication, wireless backhaul, mobile networks, cooperative communication, cooperative multipoint (CoMP), receiving-end interference cancellation, and the like.

In 5G systems, hybrid FSK and QAM modulation (FQAM) and Sliding Window Superposition Coding (SWSC) as Advanced Code Modulation (ACM), and Filter Bank Multicarrier (FBMC), non-orthogonal multiple access (NOMA) and Sparse Code Multiple Access (SCMA) as advanced access technologies have been developed.

The transmission from the base station to the User Equipment (UE) is referred to as downlink and the transmission from the UE to the base station is referred to as uplink.

In describing embodiments of the present disclosure, descriptions related to technical contents that are well known in the art and are not directly associated with the present disclosure will be omitted. Such unnecessary description is omitted so as to prevent obscuring the main idea of the present disclosure and to more clearly convey the main idea.

For the same reason, some elements may be enlarged, omitted, or schematically shown in the drawings. Furthermore, the size of each element does not fully reflect the actual size. In the drawings, identical or corresponding elements have identical reference numerals.

The advantages and features of the present disclosure and the manner in which they are accomplished will become apparent by reference to the embodiments that are described in detail below in conjunction with the accompanying drawings. However, the present disclosure is not limited to the embodiments set forth below, but may be implemented in various forms. The following examples are provided solely for the purpose of fully disclosing the present disclosure and informing those skilled in the art the scope of the present disclosure and are limited only by the scope of the appended claims. Throughout the specification, the same or similar reference numerals denote the same or similar elements.

Fig. 1 illustrates an example wireless communication network 100 in accordance with various embodiments of the disclosure. The embodiment of the wireless communication network 100 shown in fig. 1 is for illustration only. Other embodiments of the wireless communication network 100 may be capable of being used without departing from the scope of this disclosure.

The wireless communication network 100 includes a gndeb (gNB) 101, a gNB 102, and a gNB 103.gNB 101 communicates with gNB 102 and gNB 103. The gNB 101 is also in communication with at least one Internet Protocol (IP) network 130, such as the Internet, a private IP network, or other data network.

Other well-known terms, such as "Base Station (BS)" or "Access Point (AP)", can be used instead of "gnob" or "gNB", depending on the type of network. For convenience, the terms "gNodeB" and "gNB" are used in this disclosure to refer to the network infrastructure components that provide wireless access for remote terminals. Furthermore, other well-known terms such as "mobile station," "subscriber station," "remote terminal," "wireless terminal," or "user equipment" can be used in place of "user equipment" or "UE" depending on the type of network. For convenience, the terms "user equipment" and "UE" are used in this disclosure to refer to a remote wireless device that wirelessly accesses the gNB, whether the UE is a mobile device (such as a mobile phone or smart phone) or a fixed device (such as a desktop computer or vending machine) as is commonly known.

The gNB 102 provides wireless broadband access to the network 130 for a first plurality of User Equipment (UEs) within the coverage area 120 of the gNB 102. The first plurality of UEs includes UE 111 that may be located in a Small Business (SB), UE 112 that may be located in a business (E), UE 113 that may be located in a WiFi Hotspot (HS), UE 114 that may be located in a first residence (R), UE 115 that may be located in a second residence (R), and UE 116 that may be a mobile device (M), such as a cellular telephone, wireless laptop, wireless PDA, or the like. The gNB 103 provides wireless broadband access to the network 130 for a second plurality of UEs within the coverage area 125 of the gNB 103. The second plurality of UEs includes UE 115 and UE 116. In some embodiments, one or more of the gNBs 101-103 are capable of communicating with each other and with UEs 111-116 using 5G, long Term Evolution (LTE), LTE-A, wiMAX, or other advanced wireless communication technology.

The dashed lines illustrate the approximate extent of coverage areas 120 and 125, which are shown as approximately circular for illustration and explanation purposes only. It should be clearly understood that the coverage areas associated with the gnbs, such as coverage areas 120 and 125, can have other shapes, including irregular shapes, depending on the configuration of the gnbs and the variations in the radio environment associated with natural and man-made obstructions.

As described in more detail below, one or more of gNB 101, gNB 102, and gNB 103 includes a 2D antenna array as described in embodiments of the disclosure. In some embodiments, one or more of gNB 101, gNB 102, and gNB 103 support codebook designs and structures for systems with 2D antenna arrays.

Although fig. 1 shows one example of a wireless communication network 100, various changes can be made to fig. 1. For example, the wireless communication network 100 can include any number of gnbs and any number of UEs in any suitable arrangement. Also, the gNB 101 is capable of communicating directly with any number of UEs and providing those UEs with wireless broadband access to the network 130. Similarly, each gNB 102-103 is capable of communicating directly with the network 130 and providing direct wireless broadband access to the network 130 to the UE. Furthermore, gNB 101, gNB 102, and/or gNB 103 can provide access to other or additional external networks (such as external telephone networks or other types of data networks).

Fig. 2A and 2B illustrate a transmit path 200 and a receive path 250, respectively, in a wireless communication network according to various embodiments of the present disclosure. In the following description, transmit path 200 can be described as implemented in a gNB (such as gNB 102), while receive path 250 can be described as implemented in a UE (such as UE 116). However, it should be understood that the receive path 250 can be implemented in the gNB and the transmit path 200 can be implemented in the UE. In some embodiments, receive path 250 is configured to support codebook designs and structures for systems with 2D antenna arrays as described in embodiments of the present disclosure.

The transmit path 200 includes a channel coding and modulation block 205, a serial-to-parallel (S-to-P) block 210, an inverse N-point fast fourier transform (IFFT) block 215, a parallel-to-serial (P-to-S) block 220, an add cyclic prefix block 225, and an up-converter (UC) 230. The receive path 250 includes a down-converter (DC) 255, a remove cyclic prefix block 260, a serial-to-parallel (S-to-P) block 265, an N-point Fast Fourier Transform (FFT) block 270, a parallel-to-serial (P-to-S) block 275, and a channel decoding and demodulation block 280.

In transmit path 200, a channel coding and modulation block 205 receives a set of information bits, applies coding, such as Low Density Parity Check (LDPC) coding, and modulates input bits, such as with Quadrature Phase Shift Keying (QPSK) or Quadrature Amplitude Modulation (QAM), to generate a sequence of frequency domain modulation symbols. A serial-to-parallel (S-to-P) block 210 converts (such as demultiplexes) the serial modulation symbols into parallel data to generate N parallel symbol streams, where N is the number of IFFT/FFT points used in the gNB 102 and UE 116. The N-point IFFT block 215 performs an IFFT operation on the N parallel symbol streams to generate a time-domain output signal. Parallel-to-serial block 220 converts (such as multiplexes) the parallel time-domain output symbols from N-point IFFT block 215 to generate a serial time-domain signal. The add cyclic prefix block 225 inserts a cyclic prefix into the time domain signal. Up-converter 230 modulates (such as up-converts) the output of add cyclic prefix block 225 to an RF frequency for transmission via a wireless channel. The signal can also be filtered at baseband before being converted to RF frequency.

The RF signal transmitted from the gNB 102 reaches the UE 116 after passing through the wireless channel, and an operation inverse to that at the gNB 102 is performed at the UE 116. The down-converter 255 down-converts the received signal to baseband frequency and the remove cyclic prefix block 260 removes the cyclic prefix to generate a serial time domain baseband signal. Serial-to-parallel block 265 converts the time-domain baseband signal to a parallel time-domain signal. The N-point FFT block 270 performs an FFT algorithm to generate N parallel frequency domain signals. Parallel-to-serial block 275 converts the parallel frequency domain signals into a sequence of modulated data symbols. The channel decoding and demodulation block 280 demodulates and decodes the modulation symbols to recover the original input data stream.

Each of the gnbs 101-103 may implement a transmit path 200 that is similar to transmitting to UEs 111-116 in the downlink and may implement a receive path 250 that is similar to receiving from UEs 111-116 in the uplink. Similarly, each of the UEs 111-116 may implement a transmit path 200 for transmitting to the gNBs 101-103 in the uplink and may implement a receive path 250 for receiving from the gNBs 101-103 in the downlink.

Each of the components in fig. 2A and 2B can be implemented using hardware alone, or using a combination of hardware and software/firmware. As a specific example, at least some of the components in fig. 2A and 2B may be implemented in software, while other components may be implemented in configurable hardware or a combination of software and configurable hardware. For example, the FFT block 270 and IFFT block 215 may be implemented as configurable software algorithms, wherein the value of the point number N may be modified depending on the implementation.

Further, although described as using an FFT and an IFFT, this is illustrative only and should not be construed as limiting the scope of the present disclosure. Other types of transforms can be used, such as Discrete Fourier Transform (DFT) and Inverse Discrete Fourier Transform (IDFT) functions. It should be appreciated that for DFT and IDFT functions, the value of the variable N may be any integer (such as 1, 2, 3, 4, etc.), while for FFT and IFFT functions, the value of the variable N may be any integer that is a power of 2 (such as 1, 2, 4, 8, 16, etc.).

Although fig. 2A and 2B show examples of wireless transmission and reception paths, various changes may be made to fig. 2A and 2B. For example, the various components in fig. 2A and 2B can be combined, further subdivided, or omitted, and additional components can be added according to particular needs. Further, fig. 2A and 2B are intended to illustrate examples of the types of transmit and receive paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communications in a wireless network.

Fig. 3A illustrates an example UE 116 according to various embodiments of the disclosure. The embodiment of UE 116 shown in fig. 3A is for illustration only, and UEs 111-115 of fig. 1 can have the same or similar configuration. However, the UE has a variety of configurations, and fig. 3A does not limit the scope of the present disclosure to any particular implementation of the UE.

UE 116 includes an antenna 305, a Radio Frequency (RF) transceiver 310, transmit (TX) processing circuitry 315, a microphone 320, and Receive (RX) processing circuitry 325.UE 116 also includes speaker 330, processor/controller 340, input/output (I/O) interface 345, input device(s) 350, display 355, and memory 360. Memory 360 includes an Operating System (OS) 361 and one or more applications 362.

RF transceiver 310 receives an incoming RF signal from antenna 305 that is transmitted by the gNB of wireless network 100. The RF transceiver 310 down-converts the incoming RF signal to generate an Intermediate Frequency (IF) or baseband signal. The IF or baseband signal is sent to RX processing circuit 325, where RX processing circuit 325 generates a processed baseband signal by filtering, decoding, and/or digitizing the baseband or IF signal. The RX processing circuit 325 sends the processed baseband signals to a speaker 330 (such as for voice data) or to a processor/controller 340 (such as for web-browsing data) for further processing.

TX processing circuitry 315 receives analog or digital voice data from microphone 320 or other outgoing baseband data (such as network data, email, or interactive video game data) from processor/controller 340. TX processing circuitry 315 encodes, multiplexes, and/or digitizes the outgoing baseband data to generate a processed baseband or IF signal. RF transceiver 310 receives an outgoing processed baseband or IF signal from TX processing circuitry 315 and up-converts the baseband or IF signal to an RF signal that is transmitted via antenna 305.

Processor/controller 340 can include one or more processors or other processing devices and execute OS 361 stored in memory 360 to control the overall operation of UE 116. For example, processor/controller 340 may be capable of controlling the reception of forward channel signals and the transmission of reverse channel signals by RF transceiver 310, RX processing circuit 325, and TX processing circuit 315 in accordance with well-known principles. In some embodiments, processor/controller 340 includes at least one microprocessor or microcontroller.

Processor/controller 340 is also capable of executing other processes and programs resident in memory 360, such as operations for channel quality measurement and reporting for systems having 2D antenna arrays as described in embodiments of the present disclosure. Processor/controller 340 is capable of moving data into and out of memory 360 as needed to perform the process. In some embodiments, the processor/controller 340 is configured to execute the application 362 based on the OS 361 or in response to a signal received from the gNB or operator. The processor/controller 340 is also coupled to an I/O interface 345, where the I/O interface 345 provides the UE 116 with the ability to connect to other devices, such as laptop determinants and handheld determinants. I/O interface 345 is the communication path between these accessories and processor/controller 340.

The processor/controller 340 is also coupled to an input device(s) 350 and a display 355. An operator of UE 116 can input data into UE 116 using input device(s) 350. Display 355 may be a liquid crystal display or other display capable of presenting text and/or at least limited graphics (such as from a website). Memory 360 is coupled to processor/controller 340. A portion of memory 360 can include Random Access Memory (RAM) and another portion of memory 360 can include flash memory or other Read Only Memory (ROM).

Although fig. 3A shows one example of UE 116, various changes can be made to fig. 3A. For example, the various components in FIG. 3A can be combined, further subdivided, or omitted, and additional components can be added according to particular needs. As a particular example, the processor/controller 340 can be divided into multiple processors, such as one or more Central Processing Units (CPUs) and one or more Graphics Processing Units (GPUs). Further, although fig. 3A shows the UE 116 configured as a mobile phone or smart phone, the UE can be configured to operate as other types of mobile or stationary devices.

Fig. 3B illustrates an example gNB 102, in accordance with various embodiments of the disclosure. The embodiment of the gNB 102 shown in FIG. 3B is for illustration only, and other gNBs of FIG. 1 can have the same or similar configuration. However, the gNB has a variety of configurations, and fig. 3B does not limit the scope of the disclosure to any particular implementation of the gNB. Note that gNB 101 and gNB 103 can include the same or similar structures as gNB 102.

As shown in fig. 3B, the gNB 102 includes a plurality of antennas 370a-370n, a plurality of RF transceivers 372a-372n, transmit (TX) processing circuitry 374, and Receive (RX) processing circuitry 376. In certain embodiments, one or more of the plurality of antennas 370a-370n comprises a 2D antenna array. The gNB 102 also includes a controller/processor 378, a memory 380, and a backhaul or network interface 382.

The RF transceivers 372a-372n receive incoming RF signals, such as signals transmitted by UEs or other gnbs, from antennas 370a-370 n. The RF transceivers 372a-372n down-convert the incoming RF signals to generate IF or baseband signals. The IF or baseband signal is sent to RX processing circuit 376, where RX processing circuit 376 generates a processed baseband signal by filtering, decoding, and/or digitizing the baseband or IF signal. The RX processing circuit 376 sends the processed baseband signals to a controller/processor 378 for further processing.

TX processing circuitry 374 receives analog or digital data (such as voice data, network data, email, or interactive video game data) from controller/processor 378. TX processing circuitry 374 encodes, multiplexes, and/or digitizes the outgoing baseband data to generate a processed baseband or IF signal. RF transceivers 372a-372n receive the outgoing processed baseband or IF signals from TX processing circuitry 374 and up-convert the baseband or IF signals to RF signals for transmission via antennas 370a-370 n.

The controller/processor 378 can include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, controller/processor 378 may be capable of controlling the reception of forward channel signals and the transmission of backward channel signals via RF transceivers 372a-372n, RX processing circuit 376, and TX processing circuit 374 in accordance with well-known principles. The controller/processor 378 is also capable of supporting additional functions, such as higher-level wireless communication functions. For example, the controller/processor 378 can perform a Blind Interference Sensing (BIS) process such as that performed by a BIS algorithm and decode the received signal from which the interference signal is subtracted. Controller/processor 378 may support any of a variety of other functions in gNB 102. In some embodiments, controller/processor 378 includes at least one microprocessor or microcontroller.

Controller/processor 378 is also capable of executing programs and other processes residing in memory 380, such as a basic OS. Controller/processor 378 is also capable of supporting channel quality measurements and reporting for systems having 2D antenna arrays as described in embodiments of the present disclosure. In some embodiments, the controller/processor 378 supports communication between entities such as web RTCs. Controller/processor 378 is capable of moving data into and out of memory 380 as needed to perform the process.

The controller/processor 378 is also coupled to a backhaul or network interface 382. The backhaul or network interface 382 allows the gNB 102 to communicate with other devices or systems through a backhaul connection or through a network. The backhaul or network interface 382 can support communication through any suitable wired or wireless connection(s). For example, when the gNB 102 is implemented as part of a cellular communication system (such as one supporting 5G or new radio access technologies or NR, LTE, or LTE-a), the backhaul or network interface 382 can allow the gNB 102 to communicate with other gnbs over wired or wireless backhaul connections. When the gNB 102 is implemented as an access point, the backhaul or network interface 382 can allow the gNB 102 to communicate with a larger network (such as the internet) through a wired or wireless local area network or through a wired or wireless connection. The backhaul or network interface 382 includes any suitable structure, such as an ethernet or RF transceiver, that supports communication over a wired or wireless connection.

A memory 380 is coupled to the controller/processor 378. A portion of memory 380 can include RAM and another portion of memory 380 can include flash memory or other ROM. In some embodiments, a plurality of instructions, such as BIS algorithms, are stored in memory. The plurality of instructions are configured to cause the controller/processor 378 to perform a BIS process and decode the received signal after subtracting at least one interfering signal determined by the BIS algorithm.

As described in more detail below, the transmit and receive paths of the gNB 102 (implemented using the RF transceivers 372a-372n, TX processing circuitry 374, and/or RX processing circuitry 376) support aggregated communications with FDD and TDD cells.

Although fig. 3B shows one example of the gNB 102, various changes may be made to fig. 3B. For example, the gNB 102 can include any number of each of the components shown in FIG. 3B. As a particular example, the access point can include multiple backhaul or network interfaces 382, and the controller/processor 378 can support routing functions to route data between different network addresses. As another specific example, while shown as including a single instance of TX processing circuitry 374 and a single instance of RX processing circuitry 376, the gNB 102 can include multiple instances of each (such as one for each RF transceiver).

In order to enhance the coverage of 5G wireless communication systems, one implementation is to erect repeater stations at the cell edge (or area where the cell signal is poorly covered). In general, a repeater is generally divided into two sides, a base station side and a terminal side. Fig. 4 illustrates an example network including NCR in accordance with various embodiments of the present disclosure. As shown in fig. 4, for the downlink of the base station, the repeater receives a Radio Frequency (RF) signal from the base station at the base station. These radio frequency signals pass through an amplifier built in the repeater, and the amplified signals are transmitted to the terminal equipment at the terminal side of the repeater. For the uplink of the base station, the repeater receives Radio Frequency (RF) signals from the terminal device at the terminal. These radio frequency signals pass through an amplifier built in the repeater, and the amplified signals are transmitted to the terminal equipment at the base station side of the repeater.

In general, existing repeater stations are not controllable by the base station. That is, the switch of the repeater, the time of the uplink and downlink forwarding, and the direction of the uplink and downlink forwarding are all completed by the repeater itself in a manner of realizing technical/manual setting adjustment, which is not beneficial to the flexibility of network deployment and the coverage of the repeater. One solution to overcome the above drawbacks is to integrate a terminal device for the repeater, which terminal device is capable of communicating with the network device for flexible control of the repeater. Such a repeater integrated with terminal equipment is called a network controlled repeater, i.e. NCR.

Fig. 5 illustrates an example structure of an NCR according to various embodiments of the present disclosure. As shown in fig. 5, NCR has two functional entities: a first unit and a second unit. It is to be understood that in this disclosure, the naming of the repeater (NCR) and thereof is merely exemplary and not limiting. In particular, in this disclosure, a first unit is exemplified by a network-controlled repeater mobile terminal (NCR-MT), and a second unit is exemplified by a network-controlled repeater (NCR-Fwd), wherein,

● The NCR-MT is defined as a functional entity for information interaction (e.g., side control information, side control information) with the base station. The link that the NCR-MT interacts with the base station is referred to herein as a control link (C-link). The side control information is used at least for controlling NCR-Fwd.

● NCR-Fwd is defined as a functional entity for amplifying and forwarding radio frequency signals (e.g., uplink/downlink radio frequency signals) between a base station and a UE. Here, the link between NCR-Fwd and the base station is called a Backhaul link (Backhaul link); the link between NCR-Fwd and UE is called Access link (Access link).

In this disclosure, NCR may refer to either NCR-MT or NCR-Fwd, or a combination of both. In addition, the NCR-MT may also be equivalently understood as a UE, i.e. as a terminal equipment (UE).

To avoid ambiguity, the corresponding names are defined here for the transmit receive behavior of the repeater. Referring back to fig. 4, for NCR, or further for NCR-Fwd, the reception of radio frequency signals for the downlink (or, radio frequency signal reception at the base station side; or, radio frequency signal reception over the backhaul link) is referred to as downlink reception; the transmission of radio frequency signals to the downlink (or, the transmission of radio frequency signals at the terminal side; or, the transmission of radio frequency signals to the terminal; or, the transmission of radio frequency signals via the access link) is called downlink transmission; the reception of radio frequency signals on the uplink (or on the terminal side; or via the access link) is called uplink reception; the transmission of radio frequency signals to the uplink (or the transmission of radio frequency signals at the base station side; or the retransmission of radio frequency signals to the base station; or the transmission of radio frequency signals over the backhaul link) is referred to as uplink retransmission.

There is currently no indication/determination method for the on/off of NCR-Fwd, and thus the forwarding efficiency of the NCR is now to be improved.

To address the above, the present disclosure proposes a series of methods for indicating/determining the on or off of NCR-Fwd. The method can help NCR-Fwd to open or close on proper resources, thereby improving the forwarding efficiency of NCR and further improving the performance of a communication system. This will be described in detail by specific embodiments and examples.

Example one (indicating NCR-Fwd on, power adjustment, airspace adjustment)

Fig. 6 illustrates a method 600 performed by an NCR in accordance with various embodiments of the present disclosure. As shown in fig. 6, at 601, the NCR-MT determines the state of the NCR-MT (which can be understood as the NCR-MT determines the behavior of the NCR-MT); at 602, the NCR-Fwd receives and/or forwards based on the state (or behavior) of the NCR-MT.

Specifically, the method includes the NCR-Fwd receiving and/or forwarding when the NCR satisfies at least one of the following conditions, or the NCR does not apply information indicating that the NCR-Fwd is off: the NCR-MT is in a Radio Resource Control (RRC) connected state; the NCR-MT completes the random access process; the NCR-MT receives Beam Failure Recovery (BFR) feedback; the NCR-MT receives the beam indication information; the NCR-MT receives the first time slot format information; the NCR-MT receives the power information; the NCR-MT receives network power saving information.

Here, the NCR-Fwd receiving and/or forwarding may be understood as NCR-Fwd being on or NCR-Fwd being in an on state. It is also understood that the NCR does not apply information indicating that the NCR-Fwd is off, which may be understood that the NCR-Fwd does not use/does not apply information indicating that the NCR-Fwd is not receiving and/or forwarding. Optionally, receiving and/or forwarding refers to at least one of: downlink reception and/or downlink forwarding; uplink reception and/or uplink forwarding.

The specific behavior of the above conditions and corresponding NCR is further described in the examples below.

Example 1 (entering or being in RRC connected state or completing random Access procedure)

When the NCR-MT is in or enters an RRC connection state, or after the NCR-MT completes a random access process, the NCR-Fwd receives and/or forwards the NCR-Fwd in a time domain resource, or the NCR does not apply information indicating that the NCR-Fwd is closed; wherein the time domain resource refers to at least one of: channel and/or signal related time domain resources; time domain resources associated with slot format information.

Optionally, the random access procedure refers to at least one of: an initial access process; a contention-based random access procedure; a non-contention based random access procedure; a random access procedure for beam failure recovery; a random access procedure initiated by the synchronization procedure is reconfigured (Random access procedure initiated by the Reconfiguration with sync procedure).

Alternatively, in the case where the above condition is satisfied, the NCR does not apply information indicating that NCR-Fwd is off. In other words, the NCR (or NCR-Fwd) does not apply or use information indicating that the NCR-Fwd is not receiving and/or forwarding. Alternatively, the information refers to periodic shutdown information of the NCR-Fwd (or information indicating that no reception and/or forwarding is performed on time domain resources of the NCR-Fwd periodicity).

Optionally, in case the above condition is met, the NCR (or NCR-Fwd) is turned on (or at least one of downlink reception, downlink forwarding, downlink reception, downlink forwarding is performed on) the time domain resource. The time domain resource is described further below. For ease of understanding, the above time domain resources are discussed in two parts: first time domain resources for downlink transmissions and second time domain resources for uplink transmissions. That is, in the case that the above condition is satisfied, the NCR-Fwd performs downlink reception and/or downlink forwarding on the first time domain resource. In addition, when the above condition is satisfied, NCR-Fwd performs uplink reception and/or uplink forwarding on the second time domain resource.

Optionally, the first time domain resource refers to at least one of: time domain resources of the channel and/or signal (e.g., time units to which the channel and/or signal relates or resides); time domain resources corresponding to the slot format information (e.g., time units associated with or corresponding to the slot format information). Optionally, the channel and/or signal refers to at least one of a reference signal, a common channel, a common signal, a broadcast signal, and a broadcast channel. Optionally, the time domain resource of the channel and/or signal refers to at least one of:

● Time domain resources of reference signals (e.g., at least one of Synchronization Signal Block (SSB), channel state information reference signal (CSI-RS), sounding Reference Signal (SRS))

■ Alternatively, the reference signal refers to a (identified) reference signal determined by the NCR-MT during random access. For example, the reference signal refers to SSB determined by NCR-MT during random access.

■ Alternatively, the reference signal refers to a reference signal related to the control resource set #0 (CORESET # 0). Optionally, the reference signal is a reference signal for determining a typeD QCL parameter corresponding to coreset#0. For example, the reference signal is SSB for determining the typeD QCL parameter corresponding to coreset#0.

● Time domain resources of a common channel, e.g., a common Physical Downlink Control Channel (PDCCH)

■ For example, the time domain resource of the common PDCCH refers to a time domain resource (e.g., a corresponding slot and/or symbol) corresponding to a Type 0PDCCH (Type 0-PDCCH) Common Search Space (CSS). Optionally, the CSS is configured by PDCCH configuration SIB1 (pdccchconfigsib 1).

■ For example, the time domain resource of the common PDCCH refers to a time domain resource (e.g., a corresponding slot and/or symbol) corresponding to the Type0A-PDCCH CSS. Optionally, the CSS is configured by search space other system information (searchspaceothersystem information) in PDCCH configuration common (PDCCH-ConfigCommon).

■ For example, the time domain resource of the common PDCCH refers to a time domain resource (e.g., a corresponding slot and/or symbol) corresponding to a Type 1PDCCH (Type 1-PDCCH) CSS. Optionally, the CSS is configured by ra-SearchSpace in PDCCH-ConfigCommon.

■ For example, the time domain resource of the common PDCCH refers to a time domain resource (e.g., a corresponding slot and/or symbol) corresponding to a Type 2PDCCH (Type 2-PDCCH) CSS. Optionally, the CSS is configured by a paging search space (paging search space) in PDCCH-ConfigCommon.

■ For example, the time domain resource of the common PDCCH refers to a time domain resource (e.g., a corresponding slot and/or symbol) corresponding to a Type0B PDCCH (Type 0B-PDCCH) CSS.

■ For example, the time domain resource of the common PDCCH refers to a time domain resource (e.g., a corresponding slot and/or symbol) corresponding to a Type1A PDCCH (Type 1A-PDCCH) CSS.

■ For example, the time domain resource of the common PDCCH refers to a time domain resource (e.g., a corresponding slot and/or symbol) corresponding to a Type2A PDCCH (Type 2A-PDCCH) CSS.

● Time domain resources (e.g., N time units after the time unit in which the common PDCCH is located) after a common signal or a common channel (e.g., common PDCCH)

■ For example, n=1, 2, …. Taking the common PDCCH as the Type1-PDCCH CSS as an example, the NCR-Fwd is turned on (or performs downlink reception and/or downlink forwarding) in N slots after the Type1-PDCCH CSS. The reason is that a Physical Downlink Shared Channel (PDSCH) scheduled by a common PDCCH may occur in N slots after the slot in which the common PDCCH is located. The NCR is turned on at this time and UEs served by the NCR can receive the PDSCH.

■ Optionally, NCR-Fwd needs to meet the following conditions when time domain resources are turned on (or received and/or forwarded) after the common PDCCH: the multiplexing pattern (multiplexing pattern) of SSB and CORESET is multiplexing pattern 2.

● Random Access Response (RAR) window-related time domain resources

■ For example, the symbols and/or slots corresponding to the RAR window. Optionally, the start of the RAR window is related to the SSB-related Physical Random Access Channel (PRACH) occasion (e.g., the start of the RAR window is after the SSB-related PRACH occasion). Optionally, the starting point of the RAR window is determined by the time domain resource (e.g., slot or symbol) where the Type1-PDCCH CSS is located. Optionally, the RAR window is configured by a ra-Response window. Specifically, the RAR window has a length unit of a slot, and a subcarrier spacing (SCS) corresponding to the slot is based on SCS for Type1-PDCCH CSS set. The advantage of this approach is that the NCR-MT can acquire the relevant information of the RAR window through the system information and the terminal device also uses this RAR window information. The NCR-Fwd is started in the time domain resource related to the RAR window, so that the terminal equipment of the NCR service can receive the RAR.

Optionally, the time domain resource corresponding to the timeslot format information refers to a downlink time domain resource. Optionally, the downlink time domain resource is determined according to a Time Division Duplex (TDD) configuration parameter (e.g., a common TDD configuration parameter TDD-UL-DL-configuration common). Specifically, the downlink resource refers to a downlink symbol/downlink slot determined according to TDD configuration parameters.

Further, the above description of time domain resources for signals and/or channels may be combined with the description of downlink time domain resources. Taking the time domain resource of the common PDCCH as an example, the time domain resource of the common PDCCH may be understood as a downlink time domain resource among the time domain resources related to the common PDCCH. Specifically, the time domain resource related to the common PDCCH refers to a downlink symbol in a slot where the common PDCCH is located.

Optionally, the second time domain resource refers to at least one of: time domain resources of the channel and/or signal (e.g., time units to which the channel and/or signal relates/resides); time domain resources corresponding to the slot format information (e.g., time units associated/corresponding to the slot format information). Optionally, the channel and/or signal refers to a reference signal, a common channel, or a common signal. Optionally, the time domain resource of the channel and/or signal refers to at least one of:

● Time domain resources of reference signals (e.g., sounding reference signals, SRS)

● Time domain resources (e.g., M time units after the time unit in which the common PDCCH is located) after a common signal or channel (e.g., common PDCCH. See above for a detailed explanation of common PDCCH)

■ For example, m=1, 2, …. Taking the common PDCCH as the Type1-PDCCH CSS as an example, the NCR-Fwd is turned on (or uplink reception and/or uplink forwarding is performed) M slots after the slot where the Type1-PDCCH CSS is located. The benefit of this approach is that the PDSCH scheduled by the common PDCCH may correspond to the Physical Uplink Control Channel (PUCCH) (for HARQ feedback) or to message 3 (msg 3) (i.e., the PDSCH contains scheduling information for msg 3). These uplink signals may occur after the time slot of the time slot in which the common PDCCH is located. The NCR is turned on at this time and the base station (gNB) can receive these uplink signals transmitted by the UEs served by the NCR.

● Time domain resources for PRACH

■ Time domain resources of PRACH occasions (e.g., symbols and/or slots in which PRACH occasions are located). Optionally, the PRACH occasion is associated with SSB. Alternatively, the PRACH occasion refers to all PRACH occasions associated with SSBs. Alternatively, the time domain resource of the PRACH refers to the union of the time domain resources (e.g., slots or symbols) of all PRACH occasions associated with the SSB. Alternatively, the SSB refers to SSB determined by NCR-MT during random access. Alternatively, the SSB refers to an SSB associated with CORESET # 0. Optionally, the ID corresponding to the SSB is indicated by the base station (e.g., the base station indicates that it is carried by dedicated signaling; e.g., the SSB indicated by the base station is for access link beam scanning).

● RAR window-related time domain resources (or time domain resources after RAR window)

■ For example, the symbols and/or slots corresponding to the RAR window. Optionally, the starting point of the RAR window is determined by the time domain resource (e.g., slot or symbol) where the Type1-PDCCH CSS is located. Optionally, the RAR window is configured by a ra-Response window. Specifically, the RAR window has a length unit of a time slot, and SCS corresponding to the time slot is based on SCSfor Type1-PDCCH CSS set.

Alternatively, the above-described time domain resource refers to an uplink time domain resource (or, in other words, a time domain resource corresponding to the slot format information). Optionally, the uplink time domain resource is determined according to a TDD configuration parameter (e.g., a common TDD configuration parameter TDD-UL-DL-configurationcom). Specifically, the uplink time domain resource refers to an uplink symbol/uplink slot determined according to TDD configuration parameters.

Further, the above description of time domain resources for signals and/or channels may be combined with the description of uplink time domain resources. Taking the time domain resource of the common PDCCH as an example, the time domain resource of the common PDCCH may be understood as an uplink time domain resource among the time domain resources related to the common PDCCH. In particular, the time domain resource related to the common PDCCH may be understood as an uplink symbol in a slot in which the common PDCCH is located.

Example 2 (BFR feedback)

When the NCR-MT receives the BFR feedback, the NCR-Fwd receives and/or forwards the BFR feedback on the time domain resource, or the NCR does not apply information indicating that the NCR-Fwd is closed; wherein the time domain resource refers to at least one of: channel and/or signal related time domain resources; time domain resources associated with slot format information.

Here, after the NCR-MT receives the BFR feedback, it may be understood that after a period of time (e.g., 28 symbols) from when the NCR-MT receives the BFR feedback. Specifically, BFR feedback refers to PDCCH. Optionally, the PDCCH refers to at least one of: a Cyclic Redundancy Check (CRC) of a Downlink Control Information (DCI) format corresponding to the PDCCH is scrambled by a cell radio network temporary identifier (C-RNTI) or a modulation and coding scheme cell radio network temporary identifier (MCS-C-RNTI); the PDCCH is received in a recovery search space identity (recovery searchspace); the PDCCH is used to determine a completion (the completion of the contention based random access procedure) of a contention-based random access procedure; the DCI format corresponding to the PDCCH schedules a Physical Uplink Shared Channel (PUSCH) transmission (DCI format scheduling a PUSCH transmission with a same HARQ process number as for the transmission of the first PUSCH and having a toggled NDI field value) having the same HARQ process number as the HARQ process number of the transmission of the first PUSCH and having an NDI field value flipped (e.g., the first PUSCH carries a BFR media access control element (MAC CE)).

Optionally, in case the above condition is met, the NCR (or NCR-Fwd) is turned on (or at least one of downlink reception, downlink forwarding, downlink reception, downlink forwarding is performed on) the time domain resource. The time domain resource is described further below. For ease of understanding, the above time domain resources are discussed in two parts: first time domain resources for downlink transmissions and second time domain resources for uplink transmissions. Wherein, in case the above condition is met, the NCR-Fwd performs downlink reception and/or downlink forwarding on the first time domain resource. In addition, when the above condition is satisfied, NCR-Fwd performs uplink reception and/or uplink forwarding on the second time domain resource.

Optionally, the first time domain resource refers to at least one of: time domain resources of the channel and/or signal (e.g., time units to which the channel and/or signal relates/resides); time domain resources corresponding to the slot format information (e.g., time units associated/corresponding to the slot format information). Optionally, the channel and/or signal refers to at least one of a reference signal, a common channel, a common signal, a broadcast signal, and a broadcast channel. Optionally, an explanation of the time domain resources of the channel and/or signal is referred to in example 1. Optionally, the time domain resource of the channel and/or signal refers to at least one of:

● Time domain resources of reference signals (e.g., at least one of SSB, CSI-RS, SRS)

■ Optionally, the reference signal is a reference signal of an NCR-MT reporting base station (e.g., q ₀ ). Specifically, the reference signal is selected from a first reference signal, wherein the first reference signal is a reference signal (reference signals identifying the candidate beams for recovery) indicating a candidate beam for recovery. For example, the time domain resource of the reference signal refers to q ₀ Time domain resources of the corresponding SSB. That is, NCR-Fwd is at q ₀ And carrying out downlink receiving and/or downlink forwarding on the corresponding time domain resources of the SSB.

Optionally, the time domain resource corresponding to the timeslot format information refers to a downlink time domain resource. Optionally, the downlink time domain resource is determined according to a TDD configuration parameter (e.g., a common TDD configuration parameter TDD-UL-DL-configuration command). Specifically, the downlink resource refers to a downlink symbol/downlink slot determined according to TDD configuration parameters.

Further, the above description of time domain resources for signals and/or channels may be combined with the description of downlink time domain resources. Taking the time domain resource of the reference signal of the NCR-MT reporting base station as an example, the time domain resource of the reference signal of the NCR-MT reporting base station can be understood as a downlink time domain resource in the time domain resource of the reference signal of the NCR-MT reporting base station. Specifically, the time domain resource of the reference signal of the base station reported by the NCR-MT can be understood as a downlink symbol in a time slot where the reference signal of the base station reported by the NCR-MT is located.

Alternatively, the interpretation of the second time domain resource is the same as example 1.

Example 3 (Beam indicating information)

When the NCR-MT receives the beam indication information, the NCR-Fwd receives and/or forwards the beam indication information on the time domain resource related to the beam indication information, or the NCR does not apply information for indicating that the NCR-Fwd is closed.

Alternatively, in the case where the above condition is satisfied, the NCR does not apply information indicating that NCR-Fwd is off. In other words, the NCR (or NCR-Fwd) does not apply or use information indicating that the NCR-Fwd is not receiving and/or forwarding. Optionally, the information indicating that NCR-Fwd is off is related to the beam indication information described above. Alternatively, the information refers to periodic shutdown information of the NCR-Fwd (or information indicating that no reception and/or forwarding is performed on time domain resources of the NCR-Fwd periodicity). For example, the NCR-Fwd receives periodic shutdown information associated with a reference signal or beam, and the NCR-Fwd does not apply the periodic shutdown information associated with the reference signal or beam after the NCR-MT receives information indicating the reference signal or beam.

Optionally, when the above condition is met, the NCR-Fwd receives and/or forwards the beam indication information on the time domain resource corresponding to the beam indication information.

When the NCR receives the first slot format information, the NCR-Fwd receives and/or forwards the first slot format information on the time domain resource corresponding to the second slot format information, or the NCR does not apply information indicating that the NCR-Fwd is closed. Wherein the second slot format information refers to at least one of the following: dedicated slot format configuration information; common slot format information.

Here, after the NCR receives the first slot format information, it may be understood that after a period of time (e.g., 3 ms) from when the NCR receives the first slot format information. Alternatively, the first slot format information refers to dedicated slot format configuration information (e.g., a specific TDD configuration TDD-UL-DL-configuration).

Optionally, under the above conditions, the NCR does not apply information indicating that NCR-Fwd is off. In other words, the NCR (or NCR-Fwd) does not apply or use information indicating that the NCR-Fwd is not receiving and/or forwarding. Optionally, the information indicating that NCR-Fwd is off is related to the first slot format information. Alternatively, the information refers to periodic shutdown information of the NCR-Fwd (or information indicating that no reception and/or forwarding is performed on time domain resources of the NCR-Fwd periodicity). For example, NCR-Fwd does not apply NCR-Fwd closing information on time domain resources corresponding to the first slot format information (e.g., time domain resources corresponding to uplink symbols and/or downlink symbols).

Optionally, the power information related time domain resource refers to a time domain resource of the power information related reference signal.

Optionally, the reference signal refers to one or more reference signals.

Alternatively, the NCR not applying information indicating that NCR-Fwd is off means that NCR (or NCR-Fwd) is not applying or using information indicating that NCR-Fwd is not receiving and/or forwarding.

Alternatively, the NCR not applying information indicating that NCR-Fwd is closed refers to the NCR not applying information indicating that NCR-Fwd is closed on the first resource or a portion of the first resource. Alternatively, the information that NCR-Fwd is turned off refers to periodic off information of NCR-Fwd (or, information indicating that no reception and/or forwarding is performed on periodic time domain resources of NCR-Fwd).

The NCR-MT receives network power saving information. Here, a network may be understood as a network device. Explanation of the network energy saving information is referred to in example 6.

Example 8 (network energy saving information, power)

The NCR-Fwd receives and/or forwards power information associated with the network energy saving information. It should be appreciated that the power information associated with the network power saving information described herein is different from the power information received by the NCR-MT described above in example 5. Specifically, the power information related to the network power saving information described in this example 8 is the power information for NCR-MT, and the power information received by NCR-MT described in example 5 is the power information for NCR-Fwd. Optionally, the power information refers to information related to Energy Per Resource Element (EPRE). Alternatively, the power information refers to power information related to reference signals (e.g., SSB, CSI-RS, DM-RS). For example, the power information of the SSB, or for the NCR-MT to determine the power information of the SSB EPRE. For another example, the power information of the CSI-RS, or for the NCR-MT to determine the power information of the CSI-RS EPRE. For another example, the power information of the CSI-RS, or the power information for the NCR-MT to determine PDSCH/PDCCH demodulation reference signal (DMRS) EPRE. Optionally, the power information of the reference signals is determined by a power offset between the reference signals. For example, the power information of the SSB is indicated by the base station, and the base station indicates a power offset (e.g., EPRE offset) between the CSI-RS and the SSB, the NCR-MT obtains the power information (e.g., EPRE information) of the CSI-RS according to the above information.

Optionally, the power information related to network power saving refers to power information used/applied by time domain resources related to the network power saving information. Alternatively, the time domain resources may be seconds, milliseconds, frames, subframes, slots, sub-slots, symbols, and the like. Taking the network energy saving information as an example of the normal mode or the sleep mode, the first time domain resource is a time domain resource of the normal mode (in other words, the network device is in the normal mode at the first time domain resource), and the corresponding power information is the first power information. The second time domain resource is a time domain resource of a sleep mode (in other words, the network device is in the sleep mode in the second time domain resource), and the corresponding power information is second power information. Optionally, NCR-Fwd receives and/or forwards the power information on the second time domain resource or on a part of the second time domain resource. Optionally, the NCR-Fwd receiving and/or forwarding according to the power information means that the NCR-Fwd determines an amplification gain of the NCR-Fwd according to a power relationship (e.g., a power offset) corresponding to the first power information and the second power information, and uses the amplification gain for receiving and/or forwarding. For example, the power information is the power of SSB. According to the base station indication, the power corresponding to the SSB in the first time domain resource is 33dBm; the SSB corresponds to a power of 30dBm in the second time domain resource. In addition, the gain corresponding to NCR-Fwd in the first time domain resource is 10dB. In this case, the gain corresponding to NCR-Fwd in the second time domain resource is determined based on the above information. That is, the gain of NCR-Fwd at the second time domain resource is 10db+ (33 dBm-30 dBm) =13 dB. In this example, the base station has a corresponding downlink power drop at the second time domain resource compared to the first time domain resource, and therefore NCR-Fwd adjusts the downlink amplification gain accordingly so that the received power at the UE side is unchanged accordingly.

Optionally, the power information related to network power saving refers to power information used/applied by frequency domain resources related to the network power saving information. Alternatively, the frequency domain resource may be a frequency range, a frequency band, a cell, a Component Carrier (CC), a bandwidth part (BWP), or the like. Taking the network energy saving information as an example of the normal mode or the sleep mode, the first frequency domain resource is a frequency domain resource of the normal mode (in other words, the network device is in the normal mode at the first time domain resource), and the corresponding power information is the first power information. The second frequency domain resource is a frequency domain resource of the sleep mode (in other words, the network device is in the sleep mode in the second time domain resource), and the corresponding power information is the second power information. Optionally, the NCR-Fwd receives and/or forwards the power information on the second frequency domain resource or on a part of the second frequency domain resource. Optionally, the NCR-Fwd receiving and/or forwarding according to the power information means that the NCR-Fwd determines an amplification gain of the NCR-Fwd according to a power relationship (e.g., a power offset) corresponding to the first power information and the second power information, and uses the amplification gain for receiving and/or forwarding. For example, the power information is the power of SSB. According to the base station indication, the power corresponding to the SSB in the first frequency domain resource is 33dBm; the SSB corresponds to a power of 30dBm in the second frequency domain resource. In addition, the gain corresponding to NCR-Fwd in the first frequency domain resource is 10dB. In this case, the gain corresponding to NCR-Fwd in the second frequency domain resource is determined based on the above information. That is, the gain corresponding to NCR-Fwd in the second frequency domain resource is 10db+ (33 dBm-30 dBm) =13 dB. In this example, the base station has a corresponding downlink power drop in the second frequency domain resource as compared to the first frequency domain resource, and therefore NCR-Fwd adjusts the downlink amplification gain accordingly so that the received power at the UE side is unchanged accordingly.

Optionally, the power information related to the network energy saving refers to power information used/applied by the spatial domain resource related to the network energy saving information. Optionally, the spatial domain resource refers to a reference signal resource, or a time domain resource related to a reference signal.

Optionally, the NCR-MT receives and/or transmits signals and/or channels on time domain resources according to the corresponding power information.

Optionally, the NCR-MT receives and/or transmits signals and/or channels on frequency domain resources according to the corresponding power information.

Optionally, the NCR-MT receives and/or transmits signals and/or channels according to corresponding power information on spatial resources.

Example 9 (network energy saving information, airspace information)

The NCR-Fwd receives and/or forwards based on spatial information associated with the network energy saving information, or the NCR does not apply information indicating that the NCR-Fwd is off. Taking spatial domain information as reference signal information as an example, the NCR receives network energy saving information indicating that one reference signal is on (reference signal (RS) on) or is transmitted. After receiving the network power saving information, the NCR does not apply a shutdown indication of NCR-Fwd associated with the reference signal. Specifically, the NCR-Fwd off indication associated with the reference signal refers to an indication that NCR-Fwd is not receiving and/or forwarding on the time domain resource associated with the reference signal. Specifically, the time domain resource related to the reference signal refers to the time domain resource where the reference signal is located. Optionally, the information indicating that NCR-Fwd is off is related to spatial information. Alternatively, the information indicating that NCR-Fwd is turned off refers to periodic turn-off information of NCR-Fwd (or, information indicating that reception and/or forwarding is not performed on periodic time domain resources of NCR-Fwd). Here, the spatial information may be understood as reference signal information, antenna port information, antenna panel information, transmission Reception Point (TRP) information, and the like.

Optionally, the spatial information related to the network energy saving information refers to spatial information corresponding to a time domain resource related to the network energy saving information. Taking the network energy saving information as an example of the normal mode or the sleep mode, the first time domain resource is a time domain resource of the normal mode (in other words, the network device is in the normal mode at the first time domain resource), and corresponds to the first spatial domain information. The second time domain resource is a time domain resource of a sleep mode (in other words, the network device is in the sleep mode at the second time domain resource), corresponding to the second spatial information. Here, the second spatial information is understood as a beam or reference signal that is turned on at the second time domain resource (e.g., the reference signal at the second time domain resource is a subset of the reference signal at the first time domain resource).

Optionally, the NCR-Fwd determines a spatial filter for downlink reception and/or uplink forwarding according to the second spatial information. Optionally, the NCR-Fwd determines a spatial filter for downlink reception and/or uplink forwarding in the second time domain resource according to the second spatial information.

Optionally, the NCR-Fwd determines a spatial filter for uplink reception and/or downlink forwarding based on the second spatial information. Optionally, the NCR-Fwd determines a spatial filter for downlink reception and/or uplink forwarding in the second time domain resource according to the second spatial information.

Optionally, the NCR-Fwd determines a reference signal according to the second spatial information; wherein the NCR-Fwd receives and/or forwards on time domain resources related to the reference signal. Optionally, the NCR-Fwd determines a second reference signal according to the second spatial information; wherein the NCR-Fwd receives and/or forwards on the time domain resource associated with the second reference signal. Taking spatial domain information as reference signal information (or SSB information) as an example, the NCR obtains SSB information (e.g., ssb#0, ssb#1, ssb#2, ssb#3) from the base station. This SSB information can be understood as being indicated by the UE side beam for NCR-Fwd. Alternatively, NCR-Fwd uses the same QCL assumptions to receive these SSBs. In still another aspect, the SSB information indicates that NCR-Fwd performs downlink reception and/or downlink forwarding on time domain resources corresponding to the SSBs. The NCR also receives second spatial information corresponding to second SSB information (e.g., ssb#0, ssb#2, ssb#4, ssb#6). That is, the base station turns on ssb#0, ssb#2, ssb#4, ssb#6 in the second time domain resource. Optionally, NCR-Fwd performs downlink reception and/or downlink forwarding on SSB-corresponding time domain resources determined from intersections (ssb#0, ssb#2) of SSB information (ssb#0, ssb#1, ssb#2, ssb#3) and second SSB information (ssb#0, ssb#2, ssb#4, ssb#6). Optionally, NCR-Fwd performs uplink reception and/or uplink forwarding on the PRACH occasion-related time domain resources associated with the SSB intersections (ssb#0, ssb#2) described above.

Optionally, the NCR-MT receives and/or transmits signals and/or channels according to spatial information. Taking spatial domain information as reference signal information as an example, the NCR-MT receives and/or transmits signals and/or channels according to the reference signal information. Optionally, the signal and/or channel is associated with reference signal information. For example, the reference signal corresponds to reference signal information. For another example, the reference signal information corresponds to a reference signal and/or channel that is QCL.

The first embodiment has the beneficial effects that: an embodiment one provides a method for receiving and/or forwarding an NCR-Fwd or not performing an NCR-Fwd close indication. The method can instruct the NCR-Fwd to receive and/or forward, and/or instruct the time domain resource/amplification gain/airspace information (airspace filter) used by the NCR-Fwd in receiving and/or forwarding, so that the base station controls the NCR-Fwd to be started and the amplification gain and/or airspace filter used after the NCR-Fwd is started, and the NCR-Fwd is prevented from being closed when not suitable (for example, when gNB and UE are in communication), thereby improving the performance of the NCR-Fwd for receiving and forwarding, and further improving the performance of a communication system.

Optionally, the subcarrier spacing of the one or more slot IDs (or, alternatively, the list of slots) is determined based on the subcarrier spacing of the corresponding time domain resource (or, alternatively, the subcarrier spacing is equal to the subcarrier spacing of the corresponding time domain resource). Specific methods are described above.

For example, it indicates the first N symbols in the above one slot, where N may be 1,2,3, etc. For example, it indicates the last M symbols in the above one slot, where M may be 11, 12, 13, etc. NCR-Fwd uses the beam indicated by the beam information on these indicated symbols. For example, symbol information in one slot is indicated by a bit map. Specifically, the bit map is a 14-bit map, wherein the first bit indicates the first symbol of the slot, the second bit indicates the second symbol of the slot, and so on.

■ For another example, the symbol information refers to a SLIV (or, alternatively, a start symbol and a symbol length). Or, the symbol corresponding to the (one/each) slot information (or, the slot ID).

■ Slot ID. For example, the slot ID corresponds to the starting slot of the time domain resource (or, in other words, the slot in which the resource is located). Optionally, the subcarrier spacing of the time slots is determined according to the subcarrier spacing of the corresponding time domain resources (or, the subcarrier spacing is equal to the subcarrier spacing of the corresponding time domain resources).

The method for determining the subcarrier spacing of the time domain resource is described above.

Alternatively, the period may be obtained by the base station indication. For example, the base station indicates the value of the period (e.g., the milliseconds/slots and corresponding units described above). Optionally, the indication is a dedicated indication (e.g., MAC-CE, RRC). Alternatively, the period (in the case where the period indicated by the base station is not obtained) may be obtained by:

#2. Predefined. In particular to at least one of the following:

● For another example, the value of the time domain offset is associated with the SCS or frequency range (e.g., NCR determines the value of the time domain offset from the SCS or frequency range). For example, the default value of the slot offset is associated with the SCS (e.g., when scs=120 kHz, the slot offset value is 2, for another example, when scs=15 kHz is, the slot offset value is 1).

● For another example, the value of the slot offset is associated with the corresponding time domain resource for downstream forwarding or upstream reception (e.g., the NCR determines the value of the time domain offset based on whether the corresponding time domain resource is for downstream forwarding or upstream reception).

Optionally, the first time domain resource refers to a time domain resource with a smallest slot offset (if there are multiple time domain resources with a smallest slot offset, the time domain resource with a smallest start symbol in the multiple time domain resources) in the one or more time domain resources. Optionally, the first time domain resource is a SCS min/max time domain resource of the one or more time domain resources (in other words, SCS of the first threshold is determined based on SCS resource of SCS min/max time domain resource of the one or more time domain resources). Optionally, the first threshold is determined based on whether the first resource is for uplink or downlink (e.g., when the first time domain resource is determined to be a time domain resource for downlink according to TDD configuration information, the first threshold is a first predefined value. Optionally, in the case that the first time domain resource (or the first symbol of the first time domain resource) is used for the corresponding NCR-Fwd uplink forwarding, the offset needs to consider the influence of TA (or the offset is related to TA).

Optionally, the NCR expects the second indication (DCI) (last symbol of corresponding PDCCH) and the offset (e.g., time domain offset) of (the first symbol of) the first time domain resource of the one or more time domain resources to be greater than or equal to a second threshold (e.g., a threshold associated with a switch; e.g., a threshold associated with an NCR-Fwd switch).

Optionally, in the case that the first time domain resource (or the first symbol of the first time domain resource) is used for the corresponding NCR-Fwd uplink forwarding, the offset needs to consider the influence of TA (or the offset is related to TA).

A benefit of embodiments 1A-1B is that the NCR determines the time domain resources based on the indication of the base station such that the NCR-Fwd is turned on or off at the corresponding time domain resources (or the corresponding beam indication is applied for the NCR-Fwd at the corresponding time domain resources). Therefore, the base station can accurately control the behavior of NCR on time domain resources, and the reliability of the system is improved.

Example 1C

The NCR receives an indication; the indication corresponds to a beam ID. The beam ID may refer to the specific beam ID described above (beam ID for indicating on or off of NCR-Fwd) or a beam ID for indicating reception and/or forwarding (of beam/spatial filter) by NCR-Fwd.

Optionally, the indication corresponds to one DCI.

Optionally, the beam ID corresponds to a time domain resource.

Optionally, NCR-Fwd applies the beam indication at the time domain resource. Alternatively, NCR-Fwd uses the beam ID (associated spatial filter) for upstream reception and/or downstream forwarding at the corresponding time domain resource according to the indication.

Optionally, NCR-Fwd does not forward on the time domain resources.

Optionally, the NCR determines the time to apply the indication (or the time required to apply the indication) based on the beam ID. For example, when the beam ID is not equal to a specific value, the time to apply the indication is a first time (e.g., beam application time). For another example, when the beam ID is equal to a particular value, the time at which the indication is applied is a second time (e.g., a time at which a switch is applied. For another example, a time at which a switch is opened. For another example, a time at which a switch is closed).

Alternatively, the specific value may be one or more values. Alternatively, the specific value is at least one of-1, -2,0,1,2, for example. Optionally, the specific value is the lowest beam ID (of the base station configuration). Optionally, the particular value is base station configured.

Optionally, the NCR applies the respective indication (e.g., applies the respective beam indication) after the first time that the indication (or the feedback corresponding to the indication) is received.

Optionally, the NCR applies the respective indication (e.g., applies the respective switch indication) after a second time of receipt of the indication (or sending the indication corresponding feedback).

Example 1D

The NCR receives an indication; the indication corresponds to one or more beam IDs. The one or more beam IDs may refer to the specific beam IDs described above (beam IDs indicating on or off of NCR-Fwd) or beam IDs (of beam/spatial filter) indicating that NCR-Fwd is receiving and/or forwarding.

Optionally, the indication corresponds to one DCI.

Optionally, the (each of the) one or more beam IDs corresponds to one time domain resource.

Optionally, the NCR-Fwd applies the corresponding beam ID (beam ID for beam indication of NCR-Fwd) at the respective time domain resource. Alternatively, NCR-Fwd uses the one or more beam IDs (associated spatial filters) for uplink reception and/or downlink forwarding in the corresponding time domain resources according to the indication.

Optionally, NCR-Fwd does not forward on the corresponding time domain resources.

Optionally, the NCR determines the time to apply the indication (or the time required to apply the indication) based on the one or more beam IDs. For example, when at least one of the one or more beam IDs is equal to a particular value and the other is not equal to the particular value, the time for applying the indication is one of

● A first time (e.g., a beam application time);

● Second time (e.g., time of application of switch. Again, time of switch. Again example

Such as the time of turn on. For another example, the time of shut down);

● Longer of the first time and the second time;

● The shorter of the first time and the second time.

For another example, when none of the one or more beam IDs is equal to a particular value, the time to apply the indication is a first time (e.g., a beam application time). For another example, when the beam ID is equal to a particular value, the time at which the indication is applied is a second time (e.g., a time at which a switch is applied. For another example, a time at which a switch is opened. For another example, a time at which a switch is closed).

Example 1E

Optionally, the indication corresponds to one DCI.

Optionally, the (each of the) one or more beam IDs corresponds to a time domain resource.

Optionally, the NCR-Fwd applies the corresponding beam ID (beam ID for beam indication of NCR-Fwd) at the respective time domain resource.

Alternatively, the NCR expects that the one or more beam IDs each correspond to a particular value; alternatively, the NCR expects that none of the one or more beam IDs correspond to a particular value.

Optionally, the NCR determines the time to apply the indication (or the time required to apply the indication) based on the one or more beam IDs. For example, when none of the one or more beam IDs is equal to a particular value, the time to apply the indication is a first time (e.g., a beam application time). For another example, when the beam ID is equal to a particular value, the time at which the indication is applied is a second time (e.g., a time at which a switch is applied. For another example, a time at which a switch is opened. For another example, a time at which a switch is closed).

Alternatively, the specific value may be one or more values. Optionally, the specific value is at least one of, for example, -1, -2,0,1,2. Optionally, the specific value is the lowest beam ID (of the base station configuration). Optionally, the particular value is base station configured.

Optionally, the NCR applies the respective indication (e.g., applies the respective beam indication) after the first time that the indication signaling (or the feedback corresponding to the indication is sent) is received.

Optionally, the NCR applies the respective indication (e.g., applies the respective switch indication) after receiving the second time indicating the signaling (or sending the feedback indicating the correspondence).

For embodiments 1C-1E above, it will be appreciated that the particular beam ID is not used to indicate the beam of NCR-Fwd, but rather to indicate the on or off (in the on state or in the off state) of NCR-Fwd. In addition, beam IDs other than the specific beam ID are indicated by the beam for NCR-Fwd. Since the time of applying the beam indication and the switch indication is different, a further scheme is needed for distinguishing the application time. Thus, the following scheme is proposed to enable NCR to determine the application time of the corresponding indication signaling. Therefore, the blurring of the indicated application time is avoided, and the performance of the system is improved.

NCR behavior is described below. For example, NCR behavior associated with control links (control links) and/or backhaul links (backhaul links).

Example 1F-1

(optionally, if the NCR supports simultaneous uplink transmission of the backhaul link and the control link, or if the NCR does not support simultaneous uplink transmission of the backhaul link and the control link, or if the NCR supports only time division multiplexed uplink transmission of the backhaul link and the control link.) the NCR does not (simultaneously) transmit (or transmit uplink signals/channels) over the control link and transmit over the backhaul link at the same and/or adjacent time units. For example, the time unit may be a slot or a symbol.

Alternatively, the upstream signal/channel may be at least one of PRACH, PUSCH, PUCCH, SRS. The following takes the PRACH as an example of an uplink signal/channel.

Optionally, the subcarrier spacing (subcarrier spacing) or subcarrier spacing configuration of the time unit may be at least one of:

● The subcarrier spacing of the uplink signal/channel, or subcarrier spacing configuration. For example, a subcarrier spacing of an uplink bandwidth part (BWP) of the PRACH (with), or a subcarrier spacing configuration;

● The (correlated) subcarrier spacing of the control link, or subcarrier spacing configuration. For example, a transmission associated/corresponding subcarrier spacing of the control link, or a subcarrier spacing configuration;

● The (correlated) subcarrier spacing of the backhaul link, or subcarrier spacing configuration. For example, a subcarrier spacing of associated/corresponding time resources for transmission of the backhaul link (corresponding access link), or the subcarrier spacing configuration. For example, a subcarrier spacing of a transmission associated/corresponding time resource of the control link, or, the subcarrier spacing configuration;

● NCR-Fwd, or a subcarrier spacing configuration. For example, the subcarrier spacing of the associated/corresponding time resources of the access link (associated with the transmission of the control link) of NCR-Fwd, or the subcarrier spacing configuration;

● The minimum/maximum subcarrier spacing (configuration) of the uplink signal/channel and the (correlated) subcarrier spacing (configuration) of the backhaul link;

● The minimum/maximum subcarrier spacing (configuration) of the control link and the (correlated) subcarrier spacing (configuration) of the backhaul link;

● The minimum/maximum subcarrier spacing (configuration) of the uplink signal/channel and the (correlated) subcarrier spacing (configuration) of NCR-Fwd;

● The smallest/largest of the subcarrier spacing (configuration) of the control link and the (correlated) subcarrier spacing (configuration) of NCR-Fwd.

Alternatively, the time unit may be a time unit referring to at least one of:

● Time cells of PRACH (or PRACH transmission);

● Time units of the control link. For example, control link related/corresponding time units;

● Time units of the backhaul link. For example, the (transmission of the) backhaul link is associated/corresponds to the time unit (of the time resource). For example, (transmission of) backhaul links corresponding/associated access link related/corresponding (time resource) time units;

● NCR-Fwd time units. For example, the (transmission of the) backhaul link of NCR-Fwd corresponds/is associated with the access link related/corresponding (time resource) time unit.

The method avoids the problem caused by the transmission of the NCR control link and the backhaul link in the same or similar time domain resources, and improves the reliability of a communication system.

Examples 1F-2

(optionally, if the NCR supports simultaneous uplink transmission of the backhaul link and the control link, or if the NCR does not support simultaneous uplink transmission of the backhaul link and the control link, or if the NCR supports only time division multiplexed uplink transmission of the backhaul link and the control link), the NCR is not transmitted through the backhaul link in time units overlapping (or time domain overlapping) with the uplink signal/channel (or transmission of the uplink signal/channel, or transmission of the uplink signal/channel through the control link). For example, the time unit may be a slot or a symbol.

Alternatively, the time unit may be a time unit referring to at least one of:

● Time cells of PRACH (or PRACH transmission);

The method avoids the problem caused by the transmission of the NCR control link and the backhaul link in the same or similar time domain resources, and improves the reliability of a communication system. For example, the NCR (over the backhaul link) preferentially transmits the control link, improving the reliability of the control link of the NCR.

Examples 1F-3

(optionally, if the NCR supports simultaneous uplink transmission of the backhaul link and the control link, or if the NCR does not support simultaneous uplink transmission of the backhaul link and the control link, or if the NCR supports only time division multiplexed uplink transmission of the backhaul link and the control link), the NCR does not transmit (or transmit uplink signals/channels) through the control link in time units overlapping (or time domain overlapping) with transmission of the backhaul link. For example, the time unit may be a slot or a symbol.

Alternatively, the time unit may be a time unit referring to at least one of:

● Time cells of PRACH (or PRACH transmission);

The method avoids the problem caused by the transmission of the NCR control link and the backhaul link in the same or similar time domain resources, and improves the reliability of a communication system. For example, the NCR (relative to the control link) preferentially transmits the backhaul link, improving the reliability of the backhaul link of the NCR.

Example 1G-1

The NCR does not (simultaneously) transmit over the control link (or transmit uplink signals/channels) and over the backhaul link when at least one of the following conditions is met:

● The NCR supports simultaneous uplink transmission of the backhaul link and the control link, or the NCR does not support simultaneous uplink transmission of the backhaul link and the control link, or the NCR supports only time division multiplexed uplink transmission of the backhaul link and the control link;

● When the uplink signal/channel transmitted by the control link and the interval (gap) of the backhaul link transmission are less than a predefined value (e.g., 2 symbols or 4 symbols). For example, when the interval (gap) between the first time unit of the uplink signal/channel (or uplink signal/channel transmission) of the control link (in the first time slot) and the last time unit of the backhaul link transmission (or time resource associated with the backhaul link) (in the second time slot) is less than a predefined value (e.g., N time units). Optionally, N is a positive integer (e.g., one of 1,2,3, 4). Optionally, N is related to subcarrier spacing/subcarrier spacing configuration (μ). For example, when μ=0 or μ=1 (i.e., the subcarrier spacing is 15kHz or 30 kHz), n=2. For example, when μ=2 or μ=3 (i.e., the subcarrier spacing is 60kHz or 120 kHz), n=4;

● When the uplink signal/channel transmitted by the control link and the interval (gap) of the backhaul link transmission are less than a predefined value (e.g., 2 symbols or 4 symbols). For example, when the interval (gap) between the last time unit of the uplink signal/channel (or uplink signal/channel transmission) of the control link (in the first time slot) and the first time unit of the backhaul link transmission (or time resource associated with the backhaul link) (in the second time slot) is less than a predefined value (e.g., N time units). Optionally, N is a positive integer (e.g., one of 1,2,3, 4). Optionally, N is related to subcarrier spacing/subcarrier spacing configuration (μ).

Example two (indicating NCR-Fwd off, NCR-Fwd not applying an ON (ON) indication)

Fig. 7 illustrates another method 700 performed by an NCR in accordance with various embodiments of the present disclosure. As shown in fig. 7, at 701, the NCR-MT determines the state of the NCR-MT (which may be understood as the NCR-MT determines the behavior of the NCR-MT); at 702, the NCR-Fwd does not receive and/or forward based on the state (or behavior) of the NCR-MT.

Specifically, the method includes that the NCR-Fwd does not receive and/or forward or that the NCR does not apply information indicating that the NCR-Fwd is on when at least one of the following conditions is met by the NCR: the NCR-MT completes the random access process; the NCR-MT receives BFR feedback; the NCR-MT receives the beam indication information; the NCR-MT receives the power information; the NCR-MT receives network power saving information.

The fact that NCR-Fwd is not receiving and/or forwarding is understood herein to mean that NCR-Fwd is off, or NCR-Fwd is in an off state. In addition, the NCR not applying information indicating that NCR-Fwd is on may be understood as the NCR-Fwd not using/applying information for indicating that NCR-Fwd is receiving and/or forwarding. Optionally, receiving and/or forwarding refers to at least one of: downlink reception and/or downlink forwarding; uplink reception and/or uplink forwarding.

Example 1 (random Access procedure)

Here, the random access procedure refers to at least one of: an initial access process; a contention-based random access procedure; a non-contention based random access procedure; a random access procedure for beam failure recovery; a random access procedure initiated by the synchronization procedure is reconfigured (Random access procedure initiated by the Reconfiguration with sync procedure).

When the NCR-MT completes the random access procedure, the NCR (or NCR-Fwd) is turned off (or, NCR-Fwd does not perform at least one of downlink reception, downlink forwarding, downlink reception, downlink forwarding).

The above description can also be understood as: when the NCR-MT completes the random access procedure, the NCR (or NCR-Fwd) does not apply or use information for instructing the NCR-Fwd to receive and/or forward. Alternatively, the information refers to periodic on information of NCR-Fwd (or information indicating reception and/or forwarding on periodic time domain resources of NCR-Fwd).

Alternatively, after the NCR-MT completes the random access procedure, it means that the NCR-MT receives a PDCCH, where the PDCCH is used to determine the end of the random procedure (e.g., BFR feedback). Here, the explanation of BFR feedback refers to embodiment one.

Optionally, after the NCR-MT completes the random access procedure, the NCR-MT receives a period of time after the PDCCH; wherein the PDCCH is used to determine the end of the random procedure. Alternatively, the period of time is, for example, 28 symbols.

Example 2 (BFR request)

When the NCR-MT sends a BFR request, the NCR-Fwd does not receive and/or forward, or the NCR does not apply information indicating that the NCR-Fwd is on.

Here, after the NCR-MT transmits the BFR request, it may be understood that after a period of time (e.g., 28 symbols) for which the NCR-MT transmits the BFR request. Specifically, the BFR request refers to at least one of:

Example 4 (Power information)

When the NCR-MT receives the power information, the NCR-Fwd does not receive and/or forward on the time domain resources associated with the power information, or the NCR does not apply information indicating that the NCR-Fwd is on.

Alternatively, the power information refers to an amplification gain, e.g., an amplification gain of NCR-Fwd. Optionally, the amplification gain is at a minimum (in other words, the amplification gain is 0). Alternatively, the amplification gain information corresponds to the smallest index (in other words, NCR-Fwd corresponds to an output power of 0).

In this case, the NCR-Fwd does not receive and/or forward (e.g., downlink receive and/or downlink forward, for example, uplink receive and/or uplink forward) on the time domain resource associated with the reference signal (e.g., the time domain unit on which the reference signal is located).

Optionally, the reference signal refers to one or more reference signals.

Alternatively, the information that NCR-Fwd is turned on refers to periodic on information of NCR-Fwd (or, information indicating reception and/or forwarding on periodic time domain resources of NCR-Fwd). For example, the power information contains the amplification gain used by NCR-Fwd. Wherein the amplification gain corresponds to the minimum index (in other words, the amplification gain is 0). After receiving this power information, NCR-Fwd does not apply/use NCR-Fwd on information. For another example, the power information includes an amplification gain used by NCR-Fwd and an action time corresponding to the amplification gain.

Example 7 (network energy saving information, airspace information)

The NCR-MT receives network power saving information. Here, a network may be understood as a network device. The explanation of the network energy saving information is described in example 6.

The NCR-Fwd does not receive and/or forward based on spatial information associated with the network energy saving information or the NCR does not apply information indicating that the NCR-Fwd is on. Taking spatial domain information as reference signal information as an example, the NCR receives network energy saving information indicating that one reference signal is in a closed state (RS multiplexing) or is stopped from transmitting. After receiving the network power saving information, the NCR does not apply an NCR-Fwd on indication associated with the reference signal. Specifically, the NCR-Fwd on indication associated with the reference signal refers to an indication that NCR-Fwd uses the reference signal for reception and/or forwarding in a time domain resource. Optionally, information indicating that NCR-Fwd is on is associated with the spatial information. Alternatively, the information indicating that NCR-Fwd is on refers to periodic on information of NCR-Fwd (or, information indicating that reception and/or forwarding is performed on periodic time domain resources of NCR-Fwd). Here, the spatial information may be understood as beam indication information, reference signal information, antenna port information, antenna panel information, TRP information, and the like.

Taking the airspace information as the reference information as an example, optionally, the NCR-Fwd does not receive and/or forward on the time domain resource related to the reference signal information related to the network energy-saving information. Here, taking the network power saving information as an example of the normal mode or the sleep mode, the first time domain resource is a time domain resource of the normal mode (in other words, the network device is in the normal mode at the first time domain resource), and corresponds to the first spatial domain information (the first reference signal information). The second time domain resource is a time domain resource of a sleep mode (in other words, the network device is in the sleep mode at the second time domain resource), and corresponds to second spatial information (second reference signal information). Optionally, the NCR-Fwd does not receive and/or forward on the time domain resources associated with the second reference signal information (in other words, the NCR disregards the time domain resource indication associated with the second reference signal information).

Optionally, the time domain resource related to the second reference signal information refers to a time domain resource on which the second reference signal information takes effect (in other words, NCR-Fwd receives and/or forwards on the time domain resource according to the spatial filter corresponding to the second reference signal information).

Optionally, the time domain resource related to the second reference signal information refers to a time domain unit where the reference signal corresponding to the second reference signal information is located.

Optionally, the NCR-Fwd determines a spatial filter not used for downlink reception and/or uplink forwarding according to the second spatial information. Optionally, the NCR-Fwd determines a spatial filter for downlink reception and/or uplink forwarding in the second time domain resource according to the second spatial information.

Optionally, the NCR-Fwd determines a spatial filter not used for uplink reception and/or downlink forwarding according to the second spatial information. Optionally, the NCR-Fwd determines a spatial filter for downlink reception and/or uplink forwarding in the second time domain resource according to the second spatial information.

Optionally, the NCR-Fwd determines a reference signal according to the second spatial information; wherein the NCR-Fwd receives and/or forwards on time domain resources related to the reference signal. Optionally, the NCR-Fwd determines a second reference signal according to the second spatial information; wherein the NCR-Fwd does not receive and/or forward on the time domain resources associated with the second reference signal. Taking the second spatial information as reference signal information (or SSB information) as an example, the NCR obtains SSB information (e.g., ssb#0, ssb#1, ssb#2, ssb#3) from the base station. This SSB information can be understood as being indicated by the UE side beam for NCR-Fwd. Alternatively, NCR-Fwd uses the same QCL assumptions to receive these SSBs. In still another aspect, the SSB information indicates that NCR-Fwd performs downlink reception and/or downlink forwarding on time domain resources corresponding to the SSBs. The NCR also receives second spatial information corresponding to second SSB information (e.g., ssb#0, ssb#2, ssb#4, ssb#6). Optionally, NCR-Fwd does not perform downlink reception and/or downlink forwarding on SSB-corresponding time domain resources determined from the intersection (ssb#0, ssb#2) of SSB information (ssb#0, ssb#1, ssb#2, ssb#3) and second SSB information (ssb#0, ssb#2, ssb#4, ssb#6). Optionally, NCR-Fwd does not perform uplink reception and/or uplink forwarding on the PRACH occasion-related time domain resources associated with the SSB intersections (ssb#0, ssb#2) described above.

Optionally, the NCR-MT does not receive and/or does not transmit signals and/or channels according to the spatial information. Taking the spatial domain information as the reference signal information as an example, the NCR-MT does not receive and/or does not transmit signals and/or channels according to the reference signal information. Optionally, the signal and/or channel is associated with reference signal information. For example, the reference signal corresponds to reference signal information. For another example, the reference signal corresponding to the reference signal information is QCL with the signal and/or channel.

The second embodiment has the beneficial effects that: in a second embodiment, a method is provided in which NCR-Fwd does not receive and/or forward or does not perform NCR-Fwd on indication. The method can indicate that the NCR-Fwd does not receive and/or forward, so that the base station controls the NCR-Fwd to be closed, and energy waste or unnecessary interference caused by the fact that the NCR-Fwd is opened when not appropriate (for example, when gNB and UE do not communicate) is avoided, thereby reducing the power consumption of the NCR-Fwd and further improving the performance of a communication system.
