Description

Technical Field

[0002] Reflector is a panel with a new type of intelligent passive surface, such as Reconfigurable Intelligent Surface (RIS), Intelligent Reflecting Surface (IRS), etc. It uses meta-materials to control the phase of the surface in real time to control the reflection angle of the incident wave and form reflection beams in different directions. Reconfigurable intelligent surface has the characteristics of low cost and low power consumption, and can forward signals without complex radio frequency (RF) circuits.

[0003] Figure 1 A schematic diagram of an application scenario of a reflector is provided, taking a reconfigurable intelligent surface / intelligent reflecting surface (RIS / IRS) as an example. The downlink signal sent by an access point / base station reaches a terminal after being reflected by the RIS / IRS; the uplink signal of the terminal can be reflected to the access point / base station through the reconfigurable intelligent surface.

[0210] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0211] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable in appropriate circumstances, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, the process, method, system, product or equipment comprising a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment. "And / or" in the specification and claims represents at least one of the connected objects.

[0212] The following description provides examples and does not limit the scope, applicability, or configuration set forth in the claims. Changes may be made to the functions and arrangements of the elements discussed without departing from the spirit and scope of the present disclosure. Various examples may appropriately omit, replace, or add various procedures or components. For example, the described methods may be performed in an order different from that described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.

[0213] In the design of relay and integrated access and backhaul (IAB), it is usually considered that the relay and IAB have the function of terminal (UE), and the base station can control the relay or IAB through the air interface. At the relay or IAB end, due to the transmission capability, the precoding can be calculated. In addition, if the protocol stack function is provided, dynamic scheduling and routing can be realized.

[0214] However, for reflectors such as reconfigurable intelligent surfaces (RIS), firstly, they do not have the ability to actively transmit signals, and secondly, they do not have the channel estimation capability and cannot calculate precoding. In addition, their low cost and low power consumption also have limited functional support for the protocol.

[0215] The base station usually needs to configure the following information to the node device (such as a reflector): reflection coefficient (phase and amplitude), and the corresponding usage time (time resource) of the reflection coefficient. Since the coefficient adjustment of the reflector needs to be flexible and dynamic to match the dynamic user scheduling, the embodiment of the present invention proposes a solution for the base station to control the node device through dynamic signaling DCI. The node device uses a pre-agreed RNTI (reflector RNTI) at a fixed position to detect DCI. The configuration content of DCI usually includes a reflection coefficient indication, and may also include the effective time of the reflection coefficient. Of course, the effective time of the reflection coefficient can also be a system agreement, for example, it takes effect within the agreed time after receiving the above DCI.

[0216] In this article, the node device refers to a device capable of transmitting a signal, or a device capable of transmitting and forwarding a signal is collectively referred to as a node device, which may be a reflector described in the background technology, such as a reflector panel such as RIS or IRS, and may also include a reflector controller. Of course, the reflector controller may also be integrated into the reflector panel.

[0217] The base station can control the node device through dynamic signaling (such as DCI). The content configured in the DCI usually includes a reflection coefficient indication of the node device, wherein the size of the DCI is related to the number of arrays that need to be adjusted on the node device.

[0218] Considering that the number of arrays on the node device will be very large, such as 1024 arrays (32*32), if each array is indicated separately, such as each array is controlled by 2 bits, the DCI overhead will be intolerable (2048 bits). A simple solution is to use a codebook for indication, for example, using a 32-dimensional DFT matrix to quantize the phase of the array. Assuming that there are 32 arrays in the horizontal dimension and 32 arrays in the vertical dimension, the base station will select 32 codewords from a 32-dimensional codebook to represent the phase of these arrays. Here 5*32=160 bits are required to complete the indication. If there are 64 arrays in the horizontal dimension and 16 arrays in the vertical dimension, 16 codewords need to be selected from a 64-dimensional codebook to represent it, which requires 6*16=96 bits.

[0219] From the above example, it can be seen that when indicating the phase of the node device, if the array arrangement of the node device is different, the parameters such as the selection of the codebook, the size of the codebook, and the number of codewords to be indicated are not the same, which will also lead to different DCI sizes. Therefore, the node device needs to report its own array configuration so that the network side can determine the appropriate codebook for configuration, and it is also convenient for the node device to determine the DCI format size so as to correctly monitor the PDCCH.

[0220] In order to help the base station to achieve flexible control of node devices of different specifications and improve data transmission performance, an embodiment of the present invention provides a node device information reporting method, which is applied to the node device. The node device may include a reflective panel and a node device controller. Of course, the node device controller may also be integrated into the reflective panel. Figure 2 As shown, the information reporting method of the node device includes:

[0221] Step 21: The node device sends array attribute information to the base station, where the array attribute information includes at least one of the following information:

[0222] a) Port information of the node device in the first array direction and the second array direction.

[0223] The port information indicates the array capability of the node device. Optionally, the first array direction may be perpendicular to the second array direction.

[0224] Specifically, the port information of the node device in the first array direction and the second array direction may be represented by any of the following methods:

[0225] 1) a maximum dimension of a first codebook supported by the node device in a first array direction, and a maximum dimension of a second codebook supported by the node device in a second array direction;

[0226] 2) A maximum dimension of a third codebook supported by the node device, a maximum number of codewords supported by the third codebook, and an array direction corresponding to the third codebook.

[0227] b) Spatial dimension information of the first array direction and the second array direction.

[0228] The spatial dimension information of the first array direction and the second array direction reflects the specific direction of the array direction in space. For example, the spatial dimension information of the first array direction and the second array direction may be specifically represented by any of the following methods:

[0229] 1) The unit coordinate values ​​of the first array direction and the second array direction in the global coordinate system.

[0230] Figure 3 Two array directions of the node device are shown, and the two array directions are perpendicular to each other. In the embodiment of the present invention, the unit coordinate values ​​of the two array directions in the global coordinate system can be used to represent the spatial dimensions of the two array directions.

[0231] 2) a first angle and a second angle of the first array direction in the global coordinate system, and a third angle and a fourth angle of the second array direction in the global coordinate system;

[0232] Among them, the first angle is the angle between the first array direction and the Z axis of the global coordinate system, the second angle is the angle between the projection of the first array direction on the XY plane of the global coordinate system and the X axis; the third angle is the angle between the second array direction and the Z axis of the global coordinate system, and the fourth angle is the angle between the projection of the second array direction on the XY plane of the global coordinate system and the X axis.

[0233] c) pitch angle information of the node device.

[0234] Here, the pitch angle information of the node device may be specifically represented by any of the following methods:

[0235] 1) The unit coordinate value of the normal direction of the node device in the global coordinate system.

[0236] 2) The fifth angle and the sixth angle of the normal direction of the node device in the global coordinate system, the fifth angle being the angle between the normal direction and the Z axis of the global coordinate system, and the sixth angle being the angle between the projection of the normal direction on the XY plane of the global coordinate system and the X axis. Figure 3 An example of the fifth angle Θ and the sixth angle Φ is shown.

[0237] Since the deployment positions of node devices are more diverse and flexible, it is difficult to define horizontal and vertical. In addition, the deployment angle of the node device is very useful for the base station to perform precoding design. Therefore, the embodiment of the present invention provides the base station with the above-mentioned spatial dimension information of the first array direction and the second array direction and the pitch angle information of the node device, which can also assist the base station in performing more accurate beamforming design.

[0238] After providing the array attribute information in step 21 to the base station, the base station can determine the codebook configuration information of the node device according to the array information, and the codebook configuration information includes the size of the codebook, the number of codewords, and the array direction corresponding to the codewords. For example, if the codebook size is 32 dimensions and the number of codewords is 16, it means 16 codewords of 32 dimensions. Assuming that the array direction corresponding to the codeword is the first array direction, the array direction corresponding to these 16 codewords is the first array direction.

[0239] Then, the base station sends the codebook configuration information to the node device, and specifically, the codebook configuration information can be sent through a radio resource control (RRC) message. In this way, the node device can receive the codebook configuration information, and then can configure its own array according to the codebook configuration information. In addition, it should be noted that the codebook size configured by the base station can be different from the value reported by the node device, and the content reported by the node device is usually used as a reference information for the base station to configure the codebook.

[0240] The base station can also send a predetermined DCI format (referred to as the target DCI format in this article) to the node device. The target DCI format carries reflection coefficient indication information and is scrambled by the target RNTI, for example, a certain RNTI is pre-agreed or configured as the target RNTI of the node device. In this way, the terminal can detect the target DCI format based on the size of the target DCI format using the target RNTI to obtain the indication information of the configuration parameters of the node device. Among them, the content of the DCI format includes at least L codeword numbers, and the codeword is selected from a C-dimensional codebook, and C is the size of the codebook in the codebook configuration information. The C-dimensional codebook can be pre-configured by the base station to the node device, or it can be pre-agreed between the node device and the base station. In this way, by indicating the sequence number of a specific codeword in the DCI, the corresponding codebook can be determined. The node device can configure the corresponding array according to the configuration parameters.

[0241] Here, the configuration parameter of the node device is the reflection coefficient of the array, including phase and / or amplitude. In addition, optionally, the configuration parameter of the node device may also include the effective time of the reflection coefficient. The size of the target DCI format may be configured by the base station, or calculated by the node device according to the codebook configuration information. For example, when the node device calculates the size of the target DCI format according to the codebook configuration information, specifically, the size of the codebook indication field in the target DCI format may be calculated according to the formula L*log2C, where L is the number of codewords in the codebook configuration information, and C is the size of the codebook in the codebook configuration information.

[0242] Through the above method, the node device of the embodiment of the present invention sends its array attribute information to the base station, so that the base station can configure the codebook of the node device according to the array attribute information, thereby realizing flexible control of node devices of different specifications and improving data transmission performance.

[0243] Please refer to Figure 4 , an embodiment of the present invention provides a method for receiving information of a node device, comprising:

[0244] Step 41: The base station receives array attribute information sent by the node device, where the array attribute information includes at least one of the following information:

[0245] a) Port information of the node device in the first array direction and the second array direction. Optionally, the first array direction may be perpendicular to the second array direction

[0246] b) Spatial dimension information of the first array direction and the second array direction.

[0247] c) pitch angle information of the node device.

[0248] For a more detailed description of the above information, please refer to the above introduction.

[0249] Through the above steps, the base station can obtain array attribute information of the node device, thereby providing reference information support for the base station to achieve flexible control of node devices of different specifications.

[0250] After the above step 41, the base station may determine the codebook configuration information of the node device according to the array attribute information sent by the node device, the codebook configuration information including the size of the codebook, the number of codewords and the array direction corresponding to the codewords; and then send the codebook configuration information to the node device.

[0251] In addition, the base station can also send a target DCI format encrypted by the target RNTI to the node device; wherein the target DCI format carries indication information of the configuration parameters of the node device, and the content of the DCI format includes at least L codeword numbers, and the codeword is selected from a C-dimensional codebook, and C is the size of the codebook in the codebook configuration information.

[0252] Here, the size of the target DCI format is calculated according to the codebook configuration information; the configuration parameter of the node device is the reflection coefficient of the array, including phase and / or amplitude. In addition, optionally, the configuration parameter of the node device may also include the effective time of the reflection coefficient.

[0253] Here, before sending the target DCI format, the base station may calculate the size of the codebook indication field in the target DCI format according to the formula L*log2 C, where L is the number of codewords in the codebook configuration information, and C is the size of the codebook in the codebook configuration information.

[0254] From the above, it can be seen that the information receiving method of the node device of the embodiment of the present invention enables the base station to perform more accurate beamforming design through the array attribute information reported by the node device, which can avoid network configuration errors or mismatches caused by the node device form, save DCI overhead, and reduce the complexity of PDCCH reception of the node device, saving the power consumption of the node device.
