[0002] This section is intended to provide a background or context to the embodiments of the disclosure that are recited in the claims. No description herein is admitted to be prior art by inclusion in this section.

[0003] When a network forwarding node is used in a network, the network side needs to indicate or configure the forwarding beam of the network forwarding node and the corresponding time domain resource information. One of the key issues is that the number of forwarding beams supported by the network forwarding node may be greater than the number of beams that the network side needs to use or configure, and there is uncertainty in the beam index mapping. In addition, the number of beams configured by the network side at different times may change, which further increases the complexity of the mapping relationship.

It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0054] First, some terms involved in the embodiments of the present disclosure are explained below to facilitate understanding by those skilled in the art.

[0055] Intelligent Reflecting Surface (IRS) or Reconfigurable Intelligent Surface (RIS) (hereinafter referred to as RIS for the convenience of description) is composed of a large number of low-cost electromagnetic units. The reflection or transmission direction of the signal incident on the intelligent surface can be controlled by adjusting the parameters of each unit, such as phase, amplitude or frequency, 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 future wireless communications. Generally, RIS can be controlled by the network side (such as 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 issue that RIS needs to solve.

[0056] In simple terms, an IRS consists of a series of IRS units that can be used to change the phase, amplitude, or frequency of an incoming signal. In some embodiments, signals transmitted from different antennas can be sent to the IRS, which reflects the beamformed signal to the legitimate user.

[0057] The foregoing introduces some terms and concepts involved in the embodiments of the present disclosure. The following introduces the technical features involved in the embodiments of the present disclosure.

[0058] Figure 1 A schematic diagram of an exemplary system architecture that can be applied to a beam indexing method or a beam indexing device in an embodiment of the present disclosure is shown.

[0059] like Figure 1 As shown, the system architecture includes a terminal 101, a server 102, a network 103, a network side device 104 and a network forwarding node 105; wherein, Figure 1 Any terminal 101 shown can be used as a remote terminal or a relay terminal. Communication based on proximity service can be established between the remote terminal and the relay terminal. The remote terminal can access the network directly or through the relay terminal.

[0060] The network 103 is used as a medium for providing a communication link between the terminal 101 , the server 102 and the network-side device 104 , and may be, for example, a wireless network.

[0061] Optionally, the above wireless network can use standard communication technology and / or protocol. The network is usually the Internet, but it can also be any network, including but not limited to any combination of local area network (LAN), metropolitan area network (MAN), wide area network (WAN), mobile or wireless network, dedicated network or virtual private network. In some embodiments, the data exchanged through the network is represented by technology and / or format including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPsec) can also be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technology can also be used to replace or supplement the above data communication technology.

[0062] The user can use the terminal 101 to interact with the server 102 (or other terminals) through the network 103 and the gateway side device 104 to receive or send messages, etc. The terminal can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device), a desktop computer, a virtual reality device, a smart home or a vehicle-mounted device, etc. It should be noted that the specific type of the terminal is not limited in the embodiments of the present invention.

[0063] The network side device may be a base station, a relay or an access point, etc. The base station may be a base station of 5G or later versions (e.g., 5G NRNB), or a base station in other communication systems (e.g., an eNB base station). It should be noted that the specific type of the network side device is not limited in the embodiments of the present disclosure.

[0064] When the signal is transmitted uplink and downlink between the terminal (or server) and the network side, the network forwarding node 105 (such as an intelligent reflecting surface IRS) may be required to forward the signal to adjust the signal amplitude, direction, etc.

[0065] It is understandable that those skilled in the art can set the network forwarding node at any position of the network to forward signals as needed, which is not described in detail in this embodiment.

[0066] Those skilled in the art will know that Figure 1 The number of terminals, servers, networks, network-side devices, and network forwarding nodes is merely illustrative, and any number of terminals, networks, and servers may be provided according to actual needs. This disclosure embodiment does not limit this.

[0067] Under the above system architecture, a beam indexing method is provided in an embodiment of the present disclosure, and the method can be executed by any electronic device with computing and processing capabilities.

[0068] Figure 2 The figure is a flow chart of a beam indexing method according to an exemplary embodiment.

[0069] The beam indexing method provided in the embodiments of the present disclosure can be applied to the network side. Figure 1 The network side device in the example is used as the execution subject for illustration, but the present disclosure is not limited to this.

[0070] Reference Figure 2The beam indexing method provided by the embodiment of the present disclosure may include the following steps.

[0071] Step S202: determine a logical beam index list corresponding to the network forwarding node, where the logical beam index in the logical beam index list is used to index the forwarding beam selected by the network side in the network forwarding node.

[0072] In the embodiments of the present application, the network forwarding node is an intelligent reflection surface IRS as an example for explanation, but the present application is not limited to this, and any other node device that can forward signals in the network can also be the network forwarding node in the present application.

[0073] In some embodiments, the network side may store a logical beam index list corresponding to the network forwarding node, wherein the logical beam index list is used to index the forwarding beam selected by the network side in the network forwarding node.

[0074] For example, assume that the network forwarding node actually supports 20 forwarding beams, and each forwarding beam corresponds to a different forwarding direction or forwarding width; when the network forwarding node reports its capabilities to the network side, it will send the capabilities of the forwarding beams that it can support to the network side; then the network side can select part or all of the beams from the forwarding beams actually supported by the network forwarding node according to actual needs (for example, 15 beams can be selected from the above 20 forwarding beams) so that the network side can subsequently provide beam instructions to the network forwarding node according to the selected forwarding beams (for example, the network side can select a beam from the above 15 beams when the signal is transmitted uplink or downlink, and then instruct the network forwarding node to forward the signal according to the forwarding beam selected by the network side).

[0075] In some embodiments, there is a mapping relationship (such as a one-to-one correspondence) between the indexes in the above-mentioned logical index list and the forwarding beams selected by the network side in the network forwarding node, that is, when a certain index is selected in the logical index list, the forwarding beam corresponding to the index can be known with certainty.

[0076] Step S204: perform beam indication on the network forwarding node based on the logical beam index list, so that the network forwarding node determines the target physical beam index according to the target logical beam index in the beam indication, wherein the network forwarding node determines the forwarding beam according to the target physical beam index and performs signal forwarding.

[0077] In some embodiments, when the network side instructs a network forwarding node to forward a signal, it may simultaneously send a beam indication to the network forwarding node, and the beam indication may include a target logical beam index in a logical beam index list.

[0078] When a network forwarding node receives a beam indication sent from the network side, it can parse and obtain the target logical beam index in the beam indication; at the same time, the network forwarding node can map the target logical index to the target physical beam index in the physical beam index list, so as to forward the signal according to the target physical beam index.

[0079] Among them, the physical beam index in the above physical beam index list can index the forwarding beams supported by the network forwarding node.

[0080] In some embodiments, the physical beam index in the above-mentioned physical beam index list not only indexes the forwarding beams selected by the network side in the network forwarding node, but also indexes the forwarding beams not selected by the network side in the network forwarding node.

[0081] In some embodiments, the above-mentioned physical beam index list may include not only a physical beam index list but also a state value corresponding to the beam index.

[0082] In some embodiments, when the state value of the physical beam index is a first value (for example, 1), it may represent that the forwarding beam is selected by the network side; when the state value of the physical beam index is a second value (for example, 0), it may represent that the forwarding beam is not selected by the network side.

[0083] It can be understood that the network side can perform beam indication to the network forwarding node according to the physical beam index and status value in the physical beam index list.

[0084] In some embodiments, the forwarding beam selected by the network side in the network forwarding node can also be mapped and indexed through the above physical beam index list. However, there are also forwarding beams that are not selected by the network side in the physical beam index list. If the beam is indicated through the physical beam index list, there will be redundant beam indexes, which increases the complexity of the beam index.

[0085] Indexing and indicating the forwarding beam selected by the network side in the network forwarding node through the logical beam index list can save signal indication resources and improve the accuracy of signal indication.

[0086] Figure 3 The figure is a flow chart of a beam indexing method according to an exemplary embodiment.

[0087] The beam indexing method provided in the embodiments of the present disclosure can be applied to the network side. Figure 1 The network side device in the example is used as the execution subject for illustration, but the present disclosure is not limited to this.

[0088] Reference Figure 3The beam indexing method provided by the embodiment of the present disclosure may include the following steps.

[0089] Step S302: Receive beam information reported by a network forwarding node, where the beam information includes uplink forwarding beam information or downlink forwarding beam information of the network forwarding node.

[0090] In some embodiments, the network forwarding node may upload its own capabilities to the network side when it is powered on, connected to the network, or at other time nodes (e.g., periodic time nodes). The capabilities of the network forwarding node may include beam information of forwarding beams supported by the network forwarding node. The beam information uploaded by the network forwarding node may include uplink forwarding beam information corresponding to when the network forwarding node forwards uplink signals and downlink forwarding beam information corresponding to when the network forwarding node forwards downlink signals.

[0091] The uplink forwarding beam information is used to indicate the beam information supported by the network forwarding node when performing uplink forwarding. The downlink forwarding beam information is used to indicate the beam information supported by the network forwarding node when performing downlink forwarding.

[0092] In some embodiments, the above-mentioned uplink beam information or downlink beam information may include a beam index (for example, a first beam index), beam characteristic information corresponding to each beam index (for example, beam characteristic information corresponding to the first beam index), wherein the above-mentioned beam characteristic information may include: horizontal angle direction of the beam, vertical angle direction of the beam, beam angle reference benchmark, horizontal width of the beam and vertical width of the beam.

[0093] In some embodiments, the forwarding direction of the forwarding beam can be determined by the above-mentioned horizontal angle direction of the beam, vertical angle direction of the beam, beam angle reference benchmark, etc., and the width of the forwarding beam can be determined by the horizontal width of the beam and the vertical width of the beam.

[0094] In some embodiments, the above-mentioned uplink beam information or downlink beam information may include a beam index (for example, a second beam index), beam characteristic information corresponding to each beam index (for example, beam characteristic information corresponding to the second beam index), an associated index corresponding to each beam index (for example, an associated index of the second beam index), and beam characteristic information of the associated index (for example, beam characteristic information of the associated index of the second beam index), wherein the above-mentioned beam characteristic information may include: horizontal angle direction of the beam, vertical angle direction of the beam, beam angle reference datum, horizontal width of the beam, and vertical width of the beam.

[0095] Step S304: determine the forwarding beam supported by the network forwarding node and the physical beam index corresponding to the forwarding beam according to the beam information.

[0096] In some embodiments, the beams in the beam information uploaded by the network forwarding node may be sorted and indexed.

[0097] In some embodiments, a corresponding status value can be set for each physical beam index. When the status value is a first value (for example, 1), it may represent that the forwarding beam is selected by the network side; when the status value is a second value (for example, 0), it may represent that the forwarding beam is not selected by the network side.

[0098] Step S306: Determine a physical beam index list corresponding to the network forwarding node according to the physical beam index, where the physical beam index list is used to select part or all of the forwarding beams supported by the network forwarding node.

[0099] Step S308: Map the physical beam index list to a logical beam index list based on the first mapping relationship, so as to index the forwarding beam selected by the network side in the network forwarding node through the logical beam index in the logical beam index list.

[0100] In some embodiments, the first mapping relationship may be a mapping relationship configured on the network side, and mapping may be performed between the logical beam index list and the physical beam index list.

[0101] In some embodiments, the first mapping relationship may be an explicit mapping relationship, which is configured by the network side and sent to the network forwarding node; the first mapping relationship may also be an implicit mapping relationship, which is a default configuration relationship and does not require the network side to send configuration to the network forwarding node.

[0102] In some embodiments, after the logical beam index list is generated on the network side, the network side can configure and transmit the physical beam index list (and the first mapping relationship) to the network forwarding node, so that the network forwarding node maps the target logical beam index in the beam indication sent by the network side to the target physical beam index based on the first mapping relationship, and determines the forwarding beam in the forwarding beams supported by the network forwarding node based on the physical beam index list sent by the network side and performs signal forwarding.

[0103] Step S310: determine a logical beam index list corresponding to a network forwarding node, where the logical beam index in the logical beam index list is used to index a forwarding beam selected by the network side in the network forwarding node.

[0104] In some embodiments, when the network side needs to provide beam indication to a network forwarding node (i.e., instruct the network forwarding node which beam to use for signal forwarding), it can first determine a logical beam index list corresponding to the network forwarding node.

[0105] Since the logical beam indexes in the logical beam index list correspond one-to-one to the physical beam indexes in the physical beam index list, and each physical beam index corresponds to beam characteristic information, when the network side determines a logical beam index, its corresponding beam characteristic information is also determined.

[0106] Step S312: perform beam indication on the network forwarding node based on the logical beam index list, so that the network forwarding node determines the target physical beam index according to the target logical beam index in the beam indication, wherein the network forwarding node determines the forwarding beam according to the target physical beam index and performs signal forwarding.

[0107] Figure 4 The present invention is a flowchart of a method for generating a physical beam index list according to an exemplary embodiment.

[0108] In some embodiments, the beam information uploaded by the network forwarding node may include a first beam index and beam characteristic information corresponding to the first beam index, where the first beam index is an index of a forwarding beam supported by the network forwarding node.

[0109] The following will take the first beam index as an example to explain how to generate a physical beam index list according to the beam information.

[0110] Reference Figure 4 The physical beam index list generation method provided by the embodiment of the present disclosure may include the following steps.

[0157] Reference Fig.11The beam indexing method provided by the embodiment of the present disclosure may include the following steps.

[0158] Step S1102: The network forwarding node reports forwarding beam information to the network side.

[0159] Step S1104: The network side configures a corresponding bitmap according to the forwarding beam information reported by the network node to form a physical beam index list.

[0160] Step S1106: The network side configures a first mapping relationship to map the physical beam index to a logical beam index.

[0161] Step S1108: The network side indicates the first mapping relationship to the network forwarding node, and uses a logical beam index to perform beam indication of the network forwarding node.

[0162] More specifically, the detailed scheme and description of each step in the above scheme are as follows:

[0163] Step S1102: The network forwarding node reports forwarding beam information to the network side.

[0164] 1-1) The beam forwarding beam information includes at least one of the following: uplink forwarding beam information and downlink forwarding beam information.

[0165] The uplink and downlink forwarding beam information described in 1-1-1) is reported in one of the following information formats:

[0166] First format: {first beam index, first beam characteristic information, associated beam index set of the first beam}.

[0167] Second format: {second beam index, second beam characteristic information}.

[0168] 1-1-1-1) If the first format is used for reporting, the network node reports the corresponding information list according to the network side configuration (the network forwarding node reports the format in which the network allows reporting), and the information in the list conforms to the first format. The first beam characteristic information includes at least one of the following information: horizontal angle direction of the beam, vertical angle direction of the beam, beam angle reference, 3dB bandwidth in the horizontal direction of the beam, and 3dB bandwidth in the vertical direction of the beam; the associated beam index set of the first beam includes at least one of the following information: corresponding beam index number, horizontal angle direction of the corresponding beam, vertical angle direction of the corresponding beam, 3dB bandwidth in the horizontal direction of the corresponding beam, and 3dB bandwidth in the vertical direction of the corresponding beam.

The second beam characteristic information includes at least one of the following information: beam horizontal angle direction, beam vertical angle direction, beam angle reference, beam horizontal direction 3dB bandwidth, beam vertical direction 3dB bandwidth.

[0172] One implementation example Figure 7 As shown, the first bit map is "101", therefore, the first physical beam index list includes beam index #1 and beam index #3; the second bit map is only the first beam configuration selected by the first bit map, wherein the second bit map corresponding to beam index #1 is "10", therefore, the corresponding second physical beam index list includes beam index #1-1; the second bit map corresponding to beam index #3 is "11", therefore, the corresponding second physical beam index list includes beam indexes #3-1, #3-2.

[0173] 2-2) For the beam information in the second format, the network side configures a third bit map, where the number of bits of the third bit map is equal to the number of second beam indexes, which is used to select part or all of the beams in the second beam index to form a third physical beam index list.

[0174] Step S1106: The network side configures a first mapping relationship to map the physical beam index to a logical beam index.

[0175] 3-1) The first mapping relationship, for the beam information in the first format, the network side maps the beam indexes in the first physical beam index list to the first logical beam indexes 0, 1, ..., N in sequence, where N is the number of indexes in the first physical beam index list; the network side maps the beam indexes in all second physical beam index lists to the second logical beam indexes 0, 1, ..., M in sequence, first according to the order of the associated first physical beam indexes and then according to the order of the indexes in the list, where M is the sum of the number of indexes in all second physical beam index lists.

[0176] One implementation example Figure 8 As shown, the first logical beam index includes indexes 0 and 1; the second logical beam index includes indexes 0, 1, and 2; wherein the first logical beam index 0 corresponds to physical beam #1, and the first logical beam index 1 corresponds to physical beam #3; the second logical beam index 0 corresponds to physical beam #1-1, and the second logical beam indexes 1 and 2 correspond to physical beams #3-1 and #3-2, respectively.

[0177] 3-2) The first mapping relationship, for the beam information in the second format, the network side maps the beam indexes in the third physical beam index list to logical beam indexes 0, 1, ..., L in sequence, where L is the number of indexes in the third physical beam index list.

[0178] Step S1108: The network side indicates the first mapping relationship to the network forwarding node, and uses a logical beam index to perform beam indication of the network forwarding node.
