[0038] The technology described in the embodiments of the present disclosure is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA) and other systems. The terms "system" and "network" in the embodiments of the present disclosure are often used interchangeably, and the described technology can be used for the above-mentioned systems and radio technologies as well as other systems and radio technologies. However, the following description describes a New Radio (NR) system for example purposes, and NR terms are used in most of the following descriptions, although these technologies can also be applied to applications other than NR system applications, such as the 6th Generation (6G) communication system.

[0039] Figure 1The schematic diagram shows an exemplary working scenario of the communication method and related devices that can be applied to the embodiments of the present disclosure. Figure 1 As shown, the system architecture may include a network device 110, a user terminal 120 (hereinafter referred to as a user or terminal) and a network node 130. The network node 130 may be a non-base station device such as a smart surface device or a repeater device.

[0040] If the network node is a smart surface device, the smart surface device may optionally have the function of receiving signals and adjusting the phase, amplitude or polarization of external signals; for example, it may only support energy detection or sequence reception functions but not support complex functions such as channel decoding. Optionally, the smart surface device may also support sending its own information to the terminal or base station.

[0041] If the network node is a repeater, the repeater may be any one of multiple repeaters such as direct forwarding, transparent forwarding, amplified forwarding, or demodulating and retransmitting the signal, which is not limited in the embodiments of the present disclosure.

[0042] With the research and progress of smart surface technology, smart surface technology has been studied and applied in many fields, such as millimeter wave communication, THz communication, high-speed rail and fast-moving scenarios, offshore communication, etc. It is believed that with the development of technology, it will play an increasingly important role. Among them, smart surface devices include but are not limited to: intelligent reflecting surface (IRS) devices, large intelligent surfaces (LIS), smart reflective arrays (SRA) and reconfigurable reflective arrays (RRA).

[0043] Intelligent Reflecting Surface (IRS), also known as Reconfigurable Intelligent Surface (RIS) or Intelligent Metasurface (hereinafter collectively referred to as Intelligent Surface or RIS for the convenience of description), is composed of a large number of low-cost electromagnetic units. The reflection / transmission direction of the signal incident on the intelligent surface can be controlled by adjusting the parameters of each electromagnetic unit, such as the phase, so that the signal can be reflected / transmitted in the desired direction. Due to the characteristics of low cost, low power consumption, and easy deployment, RIS is expected to become a candidate technology for 6G wireless communication. Generally, RIS can be controlled by the base station, but it is transparent to the user terminal (UE, User Equipment), that is, the UE may not know the existence of RIS. How to use RIS to assist signal transmission while being transparent to the UE is a key problem that RIS needs to solve. That is, how to implement beam indication of network nodes without user feedback.

[0044] RIS can be composed of three layers of materials and an intelligent controller. The outermost layer of the intelligent surface is a dielectric substrate with a large number of metal patches attached. Each metal patch acts as an electromagnetic unit. These metal patches directly interact with the incident signal and can change the amplitude and phase of the incident signal; the middle layer is a metal copper plate used to prevent the energy leakage of the incident signal; the innermost layer is a control circuit board controlled by the intelligent controller, which is used to adjust the changes in the amplitude and phase of the incident signal by each unit in the outermost layer. The controller connected to the intelligent surface can be implemented by a field programmable gate array (FPGA), which can not only control the electromagnetic units on the intelligent surface, but also act as a gateway to exchange information at a low rate with other parts of the communication network (such as network equipment, user terminals, etc.) through independent wireless links to achieve the purpose of mutual cooperation. Those skilled in the art can know that the above structural description of the intelligent surface is only schematic, and the intelligent surface can have any form according to actual needs. The embodiments of the present disclosure are not limited to this.

[0045] Figure 1 In the wireless communication system shown, the network node 130 is taken as an example of a smart surface, but the present disclosure is not limited to this. The signal transmitted by the network device 110 (for example, the first periodic signal transmitted periodically as described below) can be transmitted to the smart surface 130 through the incident path (also referred to as the first link), and reach the user terminal 120 from the smart surface 130 through the reflection path (also referred to as the second link). At the same time, the smart surface 130 can generate a control parameter group for each electromagnetic unit in the smart surface 130 according to the control information sent by the network device 110, combined with a predetermined codebook set or a specific electromagnetic unit adjustment algorithm, so as to control each electromagnetic unit (for example, Figure 1 The smart surface 130 shown includes 36 electromagnetic units, and those skilled in the art can adjust the number of electromagnetic units according to actual conditions), thereby adjusting the reflection or transmission characteristics of electromagnetic waves of the smart surface to determine the forwarding parameters of the signal that the smart surface 130 takes effect on the network node 130 or transmits to the network node 130.

[0046] Optionally, the electromagnetic wave reflection or transmission characteristics in this embodiment include but are not limited to: phase, amplitude, polarization characteristics of the reflected electromagnetic wave or the transmitted electromagnetic wave, and energy distribution of the reflected electromagnetic wave or the transmitted electromagnetic wave in space. In specific implementation, those skilled in the art may adjust other characteristics of the smart surface according to actual conditions.

[0047] The user terminal 120 may also be referred to as a terminal device, a user equipment (UE), a mobile station, a mobile terminal, etc. The terminal can be widely used in various scenarios, for example, device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, automatic driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0048] The network device 110 may be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation Node B (gNB) in a fifth generation (5G) mobile communication system, a next generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; it may also be a module or unit that completes some functions of a base station, for example, a centralized unit (CU) or a distributed unit (DU). The network device 20 may be a macro base station, a micro base station or an indoor station, a relay node or a donor node, etc. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the network device 110. For ease of description, the following description takes a base station as an example of the network device 110.

[0049] Those skilled in the art will know that Figure 1 The number of network devices 110, user terminals 120, and smart surfaces 130 is only illustrative, and any number of network devices, user terminals, and smart surfaces may be provided according to actual needs. This is not limited in the embodiments of the present disclosure.

[0050] In the embodiments of the present disclosure, the functions of the base station may also be performed by a module (such as a chip) in the base station, or by a control subsystem including the base station functions. The control subsystem including the base station functions here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, smart city, etc. The functions of the terminal may also be performed by a module (such as a chip or a modem) in the terminal, or by a device including the terminal functions. The functions of the network node may also be performed by a module (such as a chip) in the network node, or by a device including the network node functions.

[0051] The technical solution provided in the embodiments of the present disclosure can be applied to wireless communication between communication devices. Wireless communication between communication devices may include: wireless communication between network devices and terminals, wireless communication between network devices and network devices, wireless communication between terminals and terminals, and wireless communication between network devices and network nodes. In the embodiments of the present disclosure, the term "wireless communication" may also be referred to as "communication", and the term "communication" may also be described as "data transmission", "information transmission" or "transmission".

[0052] Those skilled in the art will know that Figure 1The number of terminals, network devices, and network nodes in the example is only illustrative, and any number of terminals, network devices, and network nodes may be provided according to actual needs. The embodiments of the present disclosure are not limited to this.

[0053] IRS consists of a large number of low-cost passive reflective elements. Each reflective element can independently induce changes in the amplitude and / or phase and / or polarization of the incident signal, that is, reconfigure the wireless propagation environment by controlling reflection. In some cases, the terminal is located in the coverage range of the smart surface device or repeater, but is beyond the coverage range of the base station associated with the smart surface or repeater. At this time, the smart surface device or relay-type device can be used for signal forwarding.

[0054] Figure 2 A flow chart of a method for a network node to forward data in an embodiment of the present disclosure is shown. Figure 2 The method provided in the embodiment may be executed by a communication device or an electronic device, which may be, for example, a network node, but the present disclosure is not limited thereto. Figure 2 As shown, the method provided by the embodiment of the present disclosure may include the following steps.

[0055] Figure 2 A flow chart of a method for a network node to forward data in an embodiment of the present disclosure is shown.

[0056] In some embodiments, the RIS may be used as a network node that can forward incident electromagnetic waves in a desired direction through beamforming.

[0057] In other embodiments, a network controlled repeater (NCR, a signal relay device) can be used as a network node. In some embodiments, the network side can send control signaling or control information to the NCR to control the forwarding beam of the NCR (for example, the following step "the network node determines the forwarding parameters of the signal that is effective for the network node or transmitted to the network node based on the control information of the network side, and the forwarding parameters include beam indication information"), so as to more effectively realize information forwarding.

[0058] In addition, there are other forwarding technologies. This disclosure refers to devices that can perform corresponding forwarding operations as network nodes. The solution provided by the embodiments of this disclosure can be applied to all nodes with similar beam forwarding functions, not limited to the RIS and NCR mentioned above.

[0059] The network side in the embodiments of the present disclosure includes a network device, which may be, for example, a base station. A base station may include or may be referred to as a base station transceiver, a wireless base station, an access point, a wireless transceiver, a node B, an evolved node B (eNB), a next generation node B, or a gigabit node B (any of which may be referred to as a gNB), a home node B, a home evolved node B, or some other appropriate terminology.

[0060] When the network node is forwarding data (for example, the network node forwards the first periodic signal received from the network device to the terminal), it may be necessary to perform continuous forwarding beam switching according to the specific configuration of the network side (for example, the configuration information of the first periodic signal). For example, when the topology of the network changes, and / or, in order to optimize signal quality and improve communication efficiency, the network node performs beam switching according to the configuration of the network side and real-time channel state information (CSI) to select the best transmission beam or forwarding beam.

[0061] Beam switching is one of the key technologies for network nodes to maintain efficient communication in complex communication environments. It allows network nodes to dynamically adjust beam directions according to channel status and network requirements, thereby optimizing signal transmission quality and improving communication efficiency. The beam switching capability of network nodes directly determines whether they can forward data as expected by the network.

[0062] For UE-specific data (referring to the signal broadcast by the network device to the specific terminal in the cell), the network side can avoid the situation where the network node cannot complete the beam switching in time through scheduling according to the network node capabilities (including the switching capabilities of the network nodes), so as to meet the data forwarding requirements. However, for the transmission of Cell-common information (referring to the signal broadcast by the network device to all terminals in the cell), the network side cannot use the network node capabilities as the configuration baseline during configuration. This is because compared with UE-specific data, Cell-common information transmission (such as broadcast signals) has a wider reception range and higher real-time requirements. Therefore, it is not possible to simply use the network node capabilities as the configuration baseline during configuration. For this reason, for the transmission design of broadcast signals, it is necessary to optimize in a targeted manner according to the capabilities of the network nodes (such as beam switching capabilities or antenna switching capabilities, including switching speed, switching accuracy, switching stability, etc.), so that the broadcast signals can be effectively forwarded by the network nodes.

[0063] In a wireless communication network, UE-specific data and Cell-common information are two different types of communication data, which differ in transmission mode, purpose and configuration requirements.

[0064] UE-specific data refers to personalized data or information for a specific UE. This data is usually closely related to the communication session, service request or application requirement of a single UE. UE-specific data will take into account the specific parameters and conditions of the UE during transmission, such as location, speed, quality of service requirements, etc., to achieve more efficient resource allocation and transmission optimization. For the transmission of UE-specific data, the network side will perform fine scheduling and resource configuration based on the capabilities of the UE and network conditions. For example, in LTE or 5G networks, the eNodeB (or gNodeB) will select an available PDCCH resource from the PDCCH (physical downlink control channel) search space for each UE to be scheduled to transmit UE-specific control information (such as DCI, downlink control information). If the UE's beam switching capability is insufficient or the beam switching cannot be completed in time, the network side can make adjustments through the scheduling strategy to avoid data loss or transmission interruption.

[0065] Cell-common information refers to information that is broadcast or shared throughout the entire cell (Cell). It is not targeted at a specific UE, but is valid for all UEs active in the cell. Cell-common information usually includes system parameters, broadcast messages, paging information, etc., which are essential for UEs to access the network, maintain connections, and receive services. For the transmission of Cell-common information, the network side cannot use the capabilities of a single UE as the configuration baseline during configuration, because this type of information needs to cover all UEs in the entire cell. Therefore, when designing a transmission scheme for broadcast signals, the beam switching capabilities and coverage of network nodes need to be fully considered to ensure that the broadcast signals can be effectively forwarded to the target area.

[0066] In S210, the network node determines the configuration information of the first periodic signal transmitted by the network device, the first periodic signal including one or more signals within one period; the configuration information includes the period of the first periodic signal and first bit map information, the first bit map information is used to indicate whether the one or more signals are effective for the network node or whether they are transmitted to the network node.

[0067] In an exemplary embodiment, a network node determines configuration information of a first periodic signal transmitted on the network side, where the first periodic signal includes one or more signals within one period (for example, the multiple signals may be multiple SSB signals); the configuration information includes the period of the first periodic signal, and first bit map information, where the first bit map information is used to indicate whether the one or more signals are effective for the network node or whether they are transmitted to the network node (i.e., whether the network device transmits the corresponding signal to the network node).

[0068] The first periodic signal in the embodiment of the present disclosure may be any periodically transmitted signal transmitted or prepared to be transmitted by the network device to the terminal. For example, for the NR system, the first periodic signal may include SSB (SynchronizationSignal / PBCH Block, synchronization signal block), but considering that the solution provided by the embodiment of the present disclosure can also be applied to future communication systems, SSB is not specifically referred to here.

[0069] In the embodiment of the present disclosure, if the first bitmap information or the first bitmap indicates that a signal among one or more signals included in the first periodic signal within a period is effective for the network node, it means that the network node needs to forward the corresponding signal. For example, the network device sends the signal to the network node, and the network node forwards the signal to the terminal.

[0070] In the embodiment of the present disclosure, if the first bitmap information or the first bitmap indicates that a signal among the one or more signals included in the first periodic signal in a period is not effective for the network node, it means that the network node does not need to forward the corresponding signal. For example, the network device sends the signal to the network node, but the network node does not need to forward the signal to the terminal.

[0071] In an exemplary embodiment, the first periodic signal is a broadcast signal.

[0072] In an exemplary embodiment, the first periodic signal is a signal used for synchronization (ie, the first periodic signal is used for synchronization), or the first periodic signal carries information used for synchronization.

[0073] For example, the periodic signal for synchronization broadcast by the base station to the terminal through the network node may include one or more of the following: Primary Synchronization Signal (PSS), used to achieve frequency synchronization and coarse time synchronization between the terminal and the base station; Secondary Synchronization Signal (SSS), used to further achieve precise time synchronization between the terminal and the base station; Physical Broadcast Channel (PBCH), PBCH itself is not a direct synchronization signal, but it carries part of the system information block (SIB), including downlink system bandwidth, system frame number (SFN) and other key information, which is essential for synchronization and subsequent communication between the terminal and the base station; Synchronization Signal Block (SSB), in order to improve the transmission efficiency and reception performance of the synchronization signal, PSS, SSS and PBCH signals (as well as the demodulation reference signal DM-RS) are organized together to form a new resource block, called a synchronization signal block (SSB).

[0074] In an exemplary embodiment, the bit length of the first bitmap information is equal to the number of bits in the second bitmap whose values ​​are the first value, and each bit of the first bitmap corresponds one-to-one to the bit in the second bitmap whose value is the first value, from high bit to bit.

[0075] The bit value in the first bit map is a first value, which indicates that the signal with the corresponding bit value in the second bit map being the first value is effective for the network node or transmitted to the network node; the bit value in the first bit map is a second value, which indicates that the signal with the corresponding bit value in the second bit map being the first value is not effective for the network node or not transmitted to the network node.

[0076] In the following examples, the first value is "1" and the second value is "0", but the present disclosure is not limited thereto. For example, in other embodiments, the first value is "0" and the second value is "1".

[0077] For example, the first bitmap information has a bit length equal to the number of bits with a value of "1" in the second bitmap, and each bit of the first bitmap corresponds to the bit with a value of "1" in the second bitmap, from high bit to low bit (from left to right, the leftmost is the highest bit and the rightmost is the lowest bit). The bit "1" in the first bitmap indicates that the signal with a corresponding bit value of "1" in the second bitmap is effective for the network node or transmitted to the network node; the bit "0" in the first bitmap indicates that the signal with a corresponding bit value of "1" in the second bitmap is not effective for the network node or not transmitted to the network node.

[0078] In an exemplary embodiment, the second bitmap is used to indicate whether the one or more signals within a period of the first periodic signal are transmitted within a cell.

[0079] For example, assuming that the second bitmap contains 8 bits, these 8 bits correspond to signal #0, signal #1, signal #2, signal #3, ..., signal #7 from the highest bit on the left to the lowest bit on the right. When the second bitmap is "11001001", it means that signal #0, signal #1, signal #4, and signal #7 are transmitted in the cell. At this time, the bit length of the first bitmap is 4, and from the high bit to the low bit, it corresponds to signal #0, signal #1, signal #4, and signal #7. Assuming that the first bitmap is "1010", it means that signal #0 and signal #4 are effective for the network node or transmitted to the network node. Signal #1 and signal #4 are not effective for the network node or are not transmitted to the network node.

[0080] In an exemplary embodiment, the bit length of the first bit map information is determined according to the bit values ​​of the third bit map and the fourth bit map; the third bit map is used to indicate whether each group of signals exists, and for the existing groups, the fourth bit map is used to indicate whether each signal in the group is transmitted within the cell; each group of signals refers to each signal within a period of the first periodic signal, which is grouped in a first quantity.

[0081] In an exemplary embodiment, the third bit map corresponds to a group in sequence from high-order bits to low-order bits, and the bits in the third bit map whose bit values ​​are the first value indicate that the corresponding group signal exists; the bits in the third bit map whose bit values ​​are the second value indicate that the corresponding group signal does not exist.

[0082] In an exemplary embodiment, for the corresponding signal group whose bit value in the third bit map is the first value, the bit value of the fourth bit map is the first value indicating that the corresponding signals in the group are transmitted within the cell, and the bit value is the second value indicating that the corresponding signals in the group are not transmitted within the cell.

[0083] In an exemplary embodiment, the bit length of the fourth bitmap is equal to the first number, and the fourth bitmap corresponds to the signals within the group in sequence from high bit positions to low bit positions.

[0084] In some embodiments, the first bitmap information, its bit length is determined according to the bit values ​​of the third bitmap and the fourth bitmap, the third bitmap indicates whether each group of signals exists, and for the existing group, the fourth bitmap indicates whether each signal in the group is transmitted in the cell. Each group of signals refers to grouping multiple signals in one period of the first periodic signal in a first quantity, and the third bitmap corresponds to a group in sequence from the high bit to the low bit, and the bit value "1" indicates that the group of signals exists, and the bit value "0" indicates that the group of signals does not exist. Further, for the corresponding signal group with the bit value of the third bitmap "1", the bit value "1" of the fourth bitmap indicates that the corresponding signal in the group is transmitted in the cell, and the bit value "0" indicates that the corresponding signal in the group is not transmitted in the cell. Among them, the bit length of the fourth bitmap is equal to the first quantity, and the fourth bitmap corresponds to the signals in the group in sequence from the high bit to the low bit (from left to right, the leftmost is the highest bit, and the rightmost is the lowest bit).

[0085] In an exemplary embodiment, the bit length of the first bitmap information is equal to the number of bits in the third bitmap whose value is the first value multiplied by the number of bits in the fourth bitmap whose value is the first value. Each bit of the first bitmap corresponds one-to-one with the bits in the fourth bitmap whose value is the first value in sequence according to the group order corresponding to the bit value of the third bitmap whose value is the first value, from high bit to low bit. The bit in the first bitmap whose value is the first value indicates that the signal whose corresponding bit in the fourth bitmap has the first value is effective for the network node or transmitted to the network node. The bit in the first bitmap whose value is the second value indicates that the signal whose corresponding bit in the fourth bitmap has the first value is effective for the network node or transmitted to the network node.

[0086] In some embodiments, the bit length of the first bit map is equal to the number of third bit map bit values ​​"1" multiplied by the number of fourth bit map bit values ​​"1"; and each bit of the first bit map corresponds one-to-one with the bit values ​​"1" in the fourth bit map according to the group sorting corresponding to the third bit map bit value "1", from high bit to low bit; bit "1" of the first bit map indicates that the signal with the corresponding bit value "1" in the fourth bit map is effective for the network node or transmitted to the network node; bit "0" indicates that the signal with the corresponding bit value "1" in the fourth bit map is not effective for the network node or not transmitted to the network node.

[0087] For example, Figure 3 As shown, an embodiment is: the first periodic signal includes multiple signals in one period as signals #0, #1, ..., #15; the first number is 4 (for illustration, and can be set according to the actual scenario), then the signals are divided into 4 groups, the first group: {signal #0, #1, #2, #3}; the second group: {signal #4, #5, #6, #7}, the third group: {signal #8, #9, #10, #11}; the fourth group: {signal #12, #13, #14, #15}, and so on. At this time, the bit length of the third bitmap is 4. Assuming that the third bitmap is "0101", it means that the second group and the fourth group exist; the bit length of the fourth bitmap is equal to the first number, which is 4 bits. Assuming that the fourth bitmap is "1010", it means that the first and third signals in each signal group are transmitted in the cell. Combined with the third bitmap, it means that signals #4, #6, #12, and #14 are transmitted in the cell.

[0088] The bit length of the first bitmap is equal to the number of "1" bits in the third bitmap multiplied by the number of "1" bits in the fourth bitmap, that is, 2*2=4 bits. The first bitmap corresponds to signals #4, #6, #12, and #14 from high bit positions to low bit positions, respectively. Assuming that the first bitmap is "1101", it means that signals #4, #6, and #14 are effective for the network node or transmitted to the network node, and signal #12 is not effective for the network node or is not transmitted to the network node.

[0089] In an exemplary embodiment, the bit length of the first bitmap information is equal to the number of bits in the fourth bitmap that have the first value. Each bit of the first bitmap corresponds one-to-one to a bit in the fourth bitmap that has the first value, from high bit to low bit. The bit in the first bitmap that has the first value indicates that the signal corresponding to the first value in the fourth bitmap within the signal group whose bit value is the first value in the third bitmap is effective for the network node or transmitted to the network node. The bit in the first bitmap that has the second value indicates that the signal corresponding to the first value in the fourth bitmap within the signal group whose bit value is the first value in the third bitmap is not effective for the network node or is not transmitted to the network node.

[0090] In some embodiments, the bit length of the first bitmap is equal to the number of bits in the fourth bitmap with a value of "1". And each bit of the first bitmap corresponds one-to-one to the bit in the fourth bitmap with a value of "1", from high bit positions to low bit positions. The first bitmap bit "1" indicates that the corresponding signal with a bit value of "1" in the fourth bitmap within the signal group with a bit value of "1" in the third bitmap is effective for the network node or transmitted to the network node. The bit "0" indicates that the corresponding signal with a bit value of "1" in the fourth bitmap within the signal group with a bit value of "1" in the third bitmap is not effective for the network node or is not transmitted to the network node.

[0091] For example, Figure 4 As shown, an embodiment is: the first periodic signal includes multiple signals in one period as signals #0, #1, ..., #15; the first number is 4, then the signals are divided into 4 groups, the first group: {signal #0, #1, #2, #3}; the second group: {signal #4, #5, #6, #7}, and so on. At this time, the bit length of the third bitmap is 4, assuming that the third bitmap is "0101", it means that the second group and the fourth group exist; the bit length of the fourth bitmap is equal to the first number, which is 4 bits. Assuming that the fourth bitmap is "1010", it means that the first and third signals in each signal group are transmitted in the cell, combined with the third bitmap, it means that signals #4, #6, #12, #14 are transmitted in the cell.

[0092] The bit length of the first bitmap is equal to the number of bits of the fourth bitmap with a value of "1", that is, 2 bits. The first bitmap corresponds to signals {#4, #12} and {#6, #14} from high bit positions to low bit positions, respectively. Assuming that the first bitmap is "10", it means that signals #4 and #12 are effective for the network node or transmitted to the network node, and signals #6 and #14 are not effective for the network node or are not transmitted to the network node.

[0093] In an exemplary embodiment, the method provided by the embodiment of the present disclosure further includes: the network node reporting a first capability value to the network device, wherein the first capability value (or referred to as capability value) represents a switching capability of the network node.

[0094] For example, the network node first uploads the first capability value to the network side, and then the network side sends the configuration information of the first periodic signal to the network node according to the first capability value, that is, the configuration information of the first periodic signal is configured according to the first capability value of the network node.

[0095] In an exemplary embodiment, the switching capability is the beam switching capability or antenna switching capability of the network node, which represents the time (or duration) for the network node to switch from one beam or antenna state to another beam or antenna state.

[0096] The method for network node forwarding data proposed in the embodiment of the present disclosure is mainly aimed at broadcast signals, so that the network side can configure corresponding forwarding resources (i.e., forwarding parameters, or forwarding beams) according to the network node capabilities (such as the switching capabilities of the network nodes), thereby improving the effectiveness of network node forwarding and thus improving the overall network performance.

[0097] In an exemplary embodiment, the network node does not expect the network device to configure configuration information of the first periodic signal that does not meet the first capability value; or, if the network node determines that the time interval between two signals is less than the first capability value based on the configuration information of the first periodic signal transmitted by the network device, the network node ignores one of the signals.

[0098] In the embodiment of the present disclosure, if the time interval between two signals that are effective for the network node or transmitted to the network node in one cycle of the first periodic signal is greater than the first capability value, the configuration is determined to meet the first capability value; otherwise, it is not met.

[0099] In an exemplary embodiment, the ignoring one of the signals includes one of the following ways: ignoring the earlier signal, or ignoring the later signal. The “earlier signal” and “later signal” here are understood as before and after in the time sequence.

[0100] For example, assuming that the first capability value reported by the network node is 2ms, if the transmission interval between two signals effective for the network node determined according to the first bitmap information is less than 2ms, any one of the two effective signals is ignored, that is, one of the effective signals is not transmitted to the network node or does not need to be forwarded by the network node. Figure 4 The two signals #4 and #12 in it.

[0101] In an exemplary embodiment, the method provided by the embodiment of the present disclosure further includes: the network node determines, based on the control information of the network device, forwarding parameters of the signal that is effective for the network node or transmitted to the network node, and the forwarding parameters include beam indication information (optionally, it may also include information such as beam effective time). The network node may forward the signal that is effective for the network node or transmitted to the network node to the terminal based on the configured forwarding parameters.

[0102] The control information in the embodiment of the present disclosure refers to the configuration information of the forwarding beam of the network node.

[0103] In an exemplary embodiment, the beam indication information includes at least one of the following: a system frame number (SFN), one or more groups of beam configuration information, and a period configuration.

[0104] In an exemplary embodiment, each set of beam configuration information includes at least one of the following: a starting time slot number, a number of continuous time slots, and beam information.

[0105] In an exemplary embodiment, the beam information may be any one of the following: a beam index number, reference signal information.

[0106] In an exemplary embodiment, the reference signal information includes at least one of the following: a reference signal name, and a reference signal index number.

[0107] In an exemplary embodiment, the beam information is related to a timeslot type, and the timeslot type is an uplink timeslot (U) or a downlink timeslot (D). When the timeslot corresponding to the beam configuration information is a downlink timeslot, it indicates the downlink beam used when the network node forwards information from the network side to the user terminal; when the timeslot corresponding to the beam configuration information is an uplink timeslot, it indicates the uplink beam used when the network node forwards information from the user terminal to the network side. Therefore, if the timeslot types corresponding to the beam configuration information are different, even if the same indication information is used, such as the same beam index number, different beam indications are represented.

[0108] In an exemplary embodiment, each set of beam configuration information has no overlapping portion in the time domain.

[0109] The embodiments of the present disclosure provide a method for a network node to determine configuration information of a first periodic signal, and a method for determining whether one or more signals within a period of the first periodic signal are effective for the network node or whether they are transmitted to the network node.

[0110] When the network side configures the forwarding signal (e.g., forwarding parameters) for the network node, the specific capabilities of the network node (e.g., beam switching capability or antenna switching capability) are combined so as not to affect the forwarding performance of the network node. For this reason, the embodiment of the present disclosure designs a forwarding signal configuration method that matches the capabilities of the network node. The solution provided by the embodiment of the present disclosure can effectively solve this problem and has good practicality.
