[0098] Before introducing the technical solutions of the embodiments of the present invention, the related technologies will be described first.

[0099] In the related technologies, more and more research has been carried out on air interface technologies. In order to flexibly expand the air interface coverage with low power consumption, more and more research has been carried out on IRS. IRS can use meta-materials to control the phase of the surface in real time. By controlling the reflection angle of the incident wave, different reflected beams can be formed, and then the wireless signals can be forwarded to other communication devices. Moreover, the IRS device has the characteristics of low cost and low power consumption, and can realize the forwarding of wireless signals without complex radio frequency circuits. However, the related technologies do not involve the technical solutions of how to establish user context using the IRS device and how to perform service data transmission with the base station.

[0100] Based on this, in various embodiments of the present invention, a first PHY entity of a first network device receives first information sent by a second PHY entity of a terminal, and sends the first information to a first MAC entity of the first network device; the first information represents information requesting scheduling or management of the terminal; the first MAC entity sends the first information to a second MAC entity of a second network device; and receives second information returned by the second MAC entity based on the first information; the second information represents information for scheduling and managing the terminal; the first MAC entity schedules or manages the terminal based on the second information.

[0101] It should be noted that in the embodiments of the present invention, a simplest protocol stack of the first network device is defined, which has the following advantages:

[0102] (1). The protocol stack of the first network device only has two layers, namely the MAC layer and the PHY layer. Through the MAC layer and the PHY layer, functions on the side of the second network device can be realized: the first network device interacts with the second network device such as a base station in the identity of a terminal to obtain control information sent by the second network device, etc., and functions on the side of the terminal can be realized: based on the control information sent by the second network device such as a base station, the terminal is scheduled or managed.

[0103] (2). By defining a fast handshaking scheme at layer two between the first network device (such as an IRS device) and the second network device (such as a base station), compared with the traditional method of establishing a link through layer three for control, a control method with short delay and real-time establishment facing the air interface can be realized;

[0104] (3). Through the MAC layer and PHY layer protocols defined at layer two in the first network device (such as an IRS device), fast handshaking at layer two can be realized. Specifically, through fast control of the MAC layer, fast handshaking between the first network device and the terminal (such as a UE), and between the first network device and the second network device (such as a base station) can be realized, which can not only reduce the control complexity of the link above the MAC layer, that is, only the link above the MAC layer between the base station and the terminal needs to be established, and there is no upper layer link on the first network device (such as an IRS device), but also reduce the implementation complexity of the first network device (such as an IRS device) and the high power consumption caused by a heavy protocol stack.

[0105] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0106] Figure 1 It is a schematic diagram of the system architecture to which the information processing method of the embodiments of the present invention is applied; as Figure 1 shown, the system includes a terminal 11, a first network device 12, and a second network device 13; wherein,

[0107] The terminal 11 is configured to send first information to the IRS device through its own second PHY entity; wherein, the first information represents information for requesting scheduling or management of the terminal.

[0108] The first network device 12, which can be an IRS device, is configured to receive the first information sent by the second PHY entity of the terminal through its own first PHY entity, and send the first information to the first MAC entity of the IRS device; the first MAC entity sends the first information to the second MAC entity of the second network device.

[0109] The second network device 13 is configured to receive the first information sent by the first MAC entity of the IRS device through its own second MAC entity, and return second information to the first MAC entity. Wherein, the second information represents information for scheduling and managing the terminal.

[0110] The first network device 12 is further configured to schedule or manage the terminal based on the second information through its own first MAC entity.

[0111] Figure 2 is a schematic diagram of the IRS device according to an embodiment of the present invention, as Figure 2 shown, the IRS may refer to a new type of intelligent passive surface, which can use metamaterials to control the phase of the surface in real time, and form reflected beams in different directions by controlling the reflection angle of the incident wave, and then forward the wireless signal to other communication devices. Figure 3 is a schematic diagram of the IRS device transmitting wireless signals, as Figure 3 shown, the IRS device can forward wireless signals without a complex radio frequency (RF) circuit.

[0112] An embodiment of the present invention provides an information processing method, which is applied to an IRS device, as Figure 4 shown, the method includes:

[0113] Step 401: The first PHY entity of the first network device receives the first information sent by the second PHY entity of the terminal, and sends the first information to the first MAC entity of the first network device; the first information represents information for requesting scheduling or management of the terminal;

[0114] Step 402: The first MAC entity sends the first information to the second MAC entity of the second network device; and receives the second information returned by the second MAC entity based on the first information; the second information represents information for scheduling and managing the terminal;

[0115] Step 403: The first MAC entity schedules or manages the terminal based on the second information.

[0116] Here, in step 401, in practical applications, the first network device may be an IRS device. Since the IRS device has the characteristics of low cost and low power consumption, and can forward wireless signals without a complex RF circuit, when signaling or data is transmitted between the terminal and the second network device, the IRS device can be used to forward the signaling or data, so as to achieve the purpose of saving the power consumption of the second network device.

[0117] Here, in steps 402 to 403, in addition to being able to forward signaling or data, the IRS device also has the function of scheduling or managing the terminal based on the control information sent by the second network device. In order to simplify the implementation method of scheduling or managing the terminal, a minimalist protocol stack can be defined on the IRS device, that is, the protocol stack of the IRS device only has two layers, the MAC layer and the PHY layer. Through the MAC layer and the PHY layer, two basic functions are realized: Function 1, the IRS device interacts with the second network device such as a base station as the identity of the terminal to obtain the control information sent by the second network device; Function 2, based on the control information sent by the second network device such as a base station, schedule or manage the terminal.

[0118] Taking the first network device as an IRS device as an example, the process of the first network device realizing the basic functions of the protocol stack through the MAC layer and the PHY layer will be described in detail in different cases below.

[0119] In the first case, according to the two basic functions implemented by the protocol stack, the first MAC entity of the IRS device is divided into two MAC entities, and the first PHY entity of the IRS device is divided into two PHY entities. In this way, through the two MAC entities and the two PHY entities, the uplink message sent by the terminal is sent to the second network device, and based on the downlink message returned by the second network device, the terminal is scheduled or managed.

[0120] In practical applications, after the first MAC entity of the IRS device is divided into two MAC entities according to the two functions implemented by the protocol stack, the two MAC entities can interact with each other. In this way, the first information sent by the terminal can be sent to the second network device through the two MAC entities.

[0121] Based on this, in an embodiment, the first MAC entity includes a third MAC entity and a fourth MAC entity, and the first PHY entity includes a third PHY entity and a fourth PHY entity; the first MAC entity sending the first information to the second MAC entity of the second network device includes:

[0122] The third MAC entity receives the first information sent by the second PHY entity through the third PHY entity; and sends the first information to the fourth MAC entity;

[0123] The fourth MAC entity sends the first information to the second MAC entity through the fourth PHY entity.

[0124] For example, Figure 3 is a schematic diagram of the protocol stack of the IRS device. As Figure 5 shown, the protocol stack of the IRS device can be divided into two protocol stacks according to two functions implemented by the protocol stack, namely the IRS-UE (User Equipment) protocol stack and the IRS-BS (Base Station) protocol stack; where

[0125] The IRS-UE protocol stack is used to complete the handshake, connection management and connection synchronization functions between the IRS device and the base station, and to interact with the base station as a terminal, so it is called IRS-UE.

[0126] The IRS-BS protocol stack is used to schedule or manage terminals under the control of the base station. For example, it realizes the beamforming function of the terminal, the transmission and reception of uplink and downlink data between the UE and the base station, and provides air interface services to users, so it is called IRB-BS.

[0127] Here, the IRS-BS protocol stack includes two parts: the third MAC entity (denoted as IRS-BS-MAC) and the third PHY entity (denoted as IRS-BS-PHY); where

[0128] IRS-BS-MAC represents the MAC protocol in the IRS-BS protocol stack and is responsible for the management of UEs within the IRS coverage area, including functions such as identity recognition information, UE location information, air interface signal shaping information, and measurement processing reported by UEs. This entity and the function of scheduling or managing UEs in the MAC of the base station (denoted as NB-MAC) are peer protocol function entities and are part of the extension of the NB-MAC function.

[0129] IRS-BS-PHY represents the PHY protocol in the IRS-BS protocol stack and is responsible for the reception and transmission of air interface signals of UEs within the IRS coverage area, including functions such as UE beamforming, beam re-forming or shaping correction.

[0130] Here, the IRS-UE protocol stack includes two parts: the fourth MAC entity (denoted as IRS-UE-MAC) and the fourth PHY entity (denoted as IRS-UE-PHY); where

[0131] IRS-UE-MAC represents the MAC protocol in the IRS-UE protocol stack, which is responsible for establishing, modifying, maintaining, and releasing connections with the base station, as well as controlling and measuring reporting functions for the IRS Panel. This entity and the function in the MAC layer of the base station responsible for IRS connection management (denoted as NB-MAC) are peer protocol function entities.

[0132] IRS-UE-PHY represents the PHY protocol in the IRS-UE protocol stack, which is responsible for processing the physical signals for the interaction between the IRS and the base station. This entity and the function in the PHY layer of the base station responsible for IRS connection management (denoted as NB-PHY) are peer protocol function entities.

[0133] In actual application, after the first MAC entity of the IRS device is divided into two MAC entities according to the two functions implemented by the protocol stack, the two MAC entities can interact with each other for user context request information to control the terminal to complete the random access process, or the two MAC entities can exchange data packets to control the uplink and downlink data transmission of the terminal.

[0134] Based on this, in one embodiment, sending the first information to the fourth MAC entity includes one of the following:

[0135] When the first information is random access information, the third MAC entity generates context request information corresponding to the terminal and sends the generated context request information to the fourth MAC entity;

[0136] When the first information is uplink data, the third MAC entity sends the uplink data to the fourth MAC entity.

[0137] For example, as Figure 5 shown, the third MAC entity (denoted as IRS-BS-MAC) of the IRS-BS protocol stack receives the first information sent by the second PHY entity of the terminal through the third PHY entity (denoted as IRS-BS-PHY); and sends the first information to the fourth MAC entity (denoted as IRS-UE-MAC) of the IRS-UE protocol stack. In this way, the interaction of user data packets or user context request information can be completed between IRS-UE-MAC and IRS-BS-MAC.

[0138] In actual application, after the first MAC entity of the IRS device is divided into two MAC entities according to the two functions implemented by the protocol stack, the MAC entity responsible for interacting with the second network device can send the context request information or uplink data sent by another MAC entity to the second network device.

[0139] Based on this, in one embodiment, sending the first information to the second MAC entity includes one of the following:

[0140] The fourth MAC entity receives the context request information sent by the third MAC entity; encapsulates the context request information into a MAC PDU, and sends it to the second MAC entity;

[0141] The fourth MAC entity receives the uplink data sent by the third MAC entity, and sends the uplink data to the second MAC entity.

[0142] For example, as Figure 5 shown, the fourth MAC entity (denoted as IRS-UE-MAC) of the IRS-UE protocol stack sends the first information to the second MAC entity of the second network device through the fourth PHY entity (denoted as IRS-UE-PHY).

[0143] In practical applications, after the first MAC entity of the IRS device is divided into two MAC entities according to the two functions implemented by the protocol stack, the MAC entity responsible for interacting with the second network device receives the second information returned by the second network device based on the processed first information.

[0144] Based on this, in one embodiment, receiving the second information returned by the second MAC entity based on the first information includes:

[0145] The fourth MAC entity receives the second information returned by the second MAC entity based on the first information, and sends the second information to the third MAC entity.

[0146] In practical applications, after the first MAC entity of the IRS device is divided into two MAC entities according to the two functions implemented by the protocol stack, the MAC entity responsible for interacting with the second network device can send the downlink message sent by the second network device to another MAC entity.

[0147] Based on this, in one embodiment, the fourth MAC entity receives the second information returned by the second MAC entity based on the first information, and sends the second information to the third MAC entity, including one of the following:

[0148] When the first information is random access information, the fourth MAC entity receives the context information corresponding to the terminal sent by the second MAC entity, and sends the context information to the third MAC entity;

[0149] When the first information is uplink data, the fourth MAC entity receives the downlink data sent by the second MAC entity and sends the downlink data to the third MAC entity.

[0150] For example, as Figure 5 shown, the fourth MAC entity (denoted as IRS-UE-MAC) of the IRS-UE protocol stack receives the second information returned by the second network device based on the first information and sends it to the third MAC entity (denoted as IRS-BS-MAC) of the IRS-BS protocol stack. In this way, the context information and downlink data in the downlink direction can be exchanged between IRS-UE-MAC and IRS-BS-MAC.

[0151] In practical applications, after the first MAC entity of the IRS device is divided into two MAC entities according to the two functions implemented by the protocol stack, the MAC entities responsible for interacting with the terminal can control the terminal to complete the random access process and control the data transmission of the terminal based on the downlink message returned by the second network device.

[0152] Based on this, in an embodiment, the first MAC entity schedules or manages the terminal based on the second information, including one of the following:

[0153] The third MAC entity receives the context information sent by the fourth MAC entity and controls the terminal to complete the random access process;

[0154] The third MAC entity receives the downlink data sent by the fourth MAC entity and sends it to the terminal through the air interface.

[0155] The implementation process of the information processing method according to the embodiments of the present invention will be described in detail below in conjunction with specific embodiments.

[0156] In an example, taking the first network device as an IRS device as an example, in combination with Figure 5 the schematic diagram of the protocol stack of the IRS device shown in Figure 6 shown, the process of the IRS device controlling the random access process of the terminal through two MAC entities is described, including:

[0157] Step 601: The terminal sends an uplink message (UL Message) to the IRS device through the air interface.

[0158] Here, the uplink message corresponds to the first information.

[0159] Step 602: The third PHY entity of the IRS device (denoted as IRS-BS-PHY) receives the uplink message sent by the UE, decodes the received uplink message to obtain the decoded message, and sends the decoded message to the third MAC entity (IRS-BS-MAC).

[0160] Step 603: After receiving the decoded message sent by the third PHY entity (denoted as IRS-BS-PHY) of the IRS device, if the received message is random access (RA) information, the third MAC entity (denoted as IRS-BS-MAC) of the IRS device generates UE context request information and sends it to the fourth MAC entity (denoted as IRS-UE-MAC).

[0161] Step 604: After receiving the message sent by IRS-BS-MAC, the fourth MAC entity (denoted as IRS-UE-MAC) of the IRS device assembles a MAC PDU carrying the context request information and sends it to the fourth PHY entity (denoted as IRS-UE-PHY).

[0162] Step 605: The fourth PHY entity (denoted as IRS-UE-PHY) of the IRS device sends the MAC PDU carrying the context request information to the base station through the air interface.

[0163] Step 606: The base station receives the context request information sent by the IRS device and sends downlink information to the IRS device through the air interface.

[0164] Here, the downlink information is the second information, that is, the new context information (New ID) of the UE.

[0165] Step 607: The fourth PHY entity (denoted as IRS-UE-PHY) of the IRS device sends the generated new context information to the fourth MAC entity (denoted as IRS-UE-MAC) in the form of a MAC PDU.

[0166] Step 608: The fourth MAC entity (denoted as IRS-UE-MAC) of the IRS device sends the UE ID information in the received new context information to the third MAC entity (denoted as IRS-BS-MAC).

[0167] Here, the fourth MAC entity of the IRS device can also save the UE ID information in the received new context information locally.

[0168] Step 609: The third MAC entity (denoted as IRS-BS-MAC) of the IRS device uses the received new context information to control the terminal to complete the random access process.

[0169] Here, the IRS device controls the random access of the terminal through two MAC entities, which has the following advantages:

[0170] (1) Define the simplest protocol stack for the IRS system. This protocol stack includes two protocol layers, namely MAC and PHY. Based on the implementation of the low-complexity protocol stack function solution, the following functions can be completed: the handshake process with the base station and the synchronization maintenance function; according to the control information of the base station, send appropriate beams to the specified UE, that is, the IRS has the ability of autonomous shaping. Through the peer definition of the protocol functions of the three functional entities of the base station, IRS, and terminal, on the premise of ensuring the functions of the simplest protocol stack of the IRS, the consistent design of the protocol functions of the three functional entities is realized.

[0171] (2) Divide the MAC layer of the IRS device into two MAC entities, and divide the PHY layer into two PHY entities, and each constitutes a protocol stack. Through two protocol stacks with different functions, the functions for the base station side are realized: the IRS device interacts with the second network device such as the base station as the identity of the terminal, sends the first information sent by the terminal to the second network device, and receives the control information sent by the second network device, and the functions for the terminal side: based on the control information sent by the second network device such as the base station, schedule or manage the terminal.

[0172] (3) The two MACs can complete the interaction of the user's data packet or the user context request information, that is, the two MAC entities can realize the fast interaction with the terminal and the base station;

[0173] (4) The MAC entity supports the fast access of the terminal and realizes the plug-and-play function.

[0174] In an example, taking the first network device as the IRS device as an example, combined with Figure 5 the schematic diagram of the protocol stack of the IRS device shown, as Figure 7 shown, describe the process of the IRS device controlling the data transmission of the terminal through two MAC entities, including:

[0175] Step 701: The terminal sends an uplink message (UL Message) to the IRS device through the air interface.

[0176] Here, the uplink message corresponds to the first information.

[0177] Step 702: The third PHY entity (denoted as IRS-BS-PHY) of the IRS device receives the uplink message sent by the UE, decodes the received uplink message to obtain the decoded message, and sends the decoded message to the third MAC entity (IRS-BS-MAC).

[0178] Step 703: After the third MAC entity of the IRS device (denoted as IRS-BS-MAC) receives the decoded message sent by the third PHY entity (denoted as IRS-BS-PHY), if the received data is uplink data, it is directly sent to the fourth MAC entity (denoted as IRS-UE-MAC).

[0179] Step 704: After the fourth MAC entity of the IRS device (denoted as IRS-UE-MAC) receives the uplink data sent by IRS-BS-MAC, it is directly sent to the fourth PHY entity (denoted as IRS-UE-PHY).

[0180] Step 705: The fourth PHY entity of the IRS device (denoted as IRS-UE-PHY) sends the uplink data to the base station through the air interface.

[0181] Step 706: The base station receives the uplink data sent by the IRS device and sends downlink information to the IRS device through the air interface.

[0182] Here, the downlink information corresponds to the second information, that is, downlink data.

[0183] Step 707: The fourth PHY entity of the IRS device (denoted as IRS-UE-PHY) sends the downlink data to the fourth MAC entity (denoted as IRS-UE-MAC).

[0184] Step 708: The fourth MAC entity of the IRS device (denoted as IRS-UE-MAC) sends the received downlink data to the third MAC entity (denoted as IRS-BS-MAC).

[0185] Step 709: The third MAC entity of the IRS device (denoted as IRS-BS-MAC) sends the received downlink data to the third PHY entity (denoted as IRS-BS-PHY).

[0186] Step 710: The third PHY entity of the IRS device (denoted as IRS-BS-PHY) sends the downlink data to the terminal through the air interface.

[0187] Here, the IRS device controls the data transmission to the terminal and has the following advantages:

[0188] (1) The protocol stack of the IRS device is simple, including only two protocol layers: MAC and PHY.

[0189] (2) The MAC layer of the IRS device is divided into two MAC entities, and the PHY layer is divided into two PHY entities, each forming a protocol stack. Through the two protocol stacks with different functions, data transmission between the terminal side and the base station side is realized.

[0190] In the second case, the first MAC entity of the IRS device can simultaneously implement the functions of the protocol stacks of IRS-UE and IRS-BS.

[0191] Specifically, the first PHY entity of the IRS device is divided into two PHY entities, and the first MAC entity of the IRS device simultaneously implements the functions of the protocol stacks of IRS-UE and IRS-BS through two physical layers.

[0192] In practical applications, the first MAC entity of the IRS device can be responsible for interacting with the terminal to obtain the first information sent by the terminal. At the same time, it can also be responsible for interacting with the second network device to send the first information sent by the terminal to the second network device.

[0193] Based on this, in one embodiment, the first MAC entity sending the first information to the second MAC entity of the second network device includes:

[0194] When the first information is random access information, the first MAC entity generates context request information, encapsulates the context request information into a MAC PDU, and sends it to the second MAC entity of the second network device;

[0195] When the first information is uplink data, the first MAC entity sends the uplink data to the second MAC entity of the second network device.

[0196] For example, Figure 8 is a schematic diagram of another protocol stack of the IRS device, as Figure 8 shown, this protocol stack includes one MAC entity and two PHY entities, where one PHY entity is responsible for interacting with the terminal, and the other PHY entity is responsible for interacting with the second network device.

[0197] In practical applications, the first MAC entity of the IRS device can be responsible for interacting with the second network device to receive the downlink information returned by the second network device and control the random access process and data transmission of the terminal.

[0198] Based on this, in one embodiment, the first MAC entity scheduling or managing the terminal based on the second information includes:

[0199] When the first information is random access information, the first MAC entity receives the context information corresponding to the terminal sent by the second MAC entity, and uses the context information to control the terminal to complete the random access process;

[0200] When the first information is uplink data, the first MAC entity receives the downlink data sent by the second MAC entity and sends it to the terminal through the air interface.

[0201] In the third case, the first MAC entity and the first PHY entity of the IRS device implement the function of sending the broadcast message and the shaping control information sent by the second network device to the terminal.

[0202] In practical applications, when the second network device sends the broadcast message and the shaping control information to the IRS device, the IRS device can use the received broadcast message and shaping control information to perform radio resource configuration or shaping control on the terminal.

[0203] Based on this, in one embodiment, the method further includes:

[0204] The first PHY entity of the IRS device receives the third information sent by the second network device; the third information is broadcast information or shaping control information;

[0205] The first PHY entity sends the third information to the first MAC entity of the IRS device;

[0206] Wherein, the third information is used for the first MAC entity to perform radio resource configuration or beamforming control on the terminal.

[0207] Here, the third information may further include other downlink messages such as operation and maintenance (OM) and control signaling.

[0208] Here, when the third information is broadcast information, the method further includes:

[0209] The first MAC entity parses the broadcast message to obtain the MIB and / or SIB, and sends the MIB and / or SIB to the terminal to perform radio resource configuration on the terminal.

[0210] Here, when the third information is shaping control information, the method further includes:

[0211] The first MAC entity generates beamforming for at least one terminal based on the shaping control information; and uses the generated beamforming to control data transmission with the at least one terminal.

[0212] It should be noted that here, the broadcast message and the shaping control information sent by the second network device can also be sent to the terminal through two MAC entities. The specific implementation process is similar to the process of sending the second information through two MAC entities and will not be elaborated here.

[0213] In one example, taking the first network device as an IRS device and the second network device as a base station as an example, combined with Figure 5 the protocol stack schematic diagram of the IRS device shown, as Figure 9 shown, the process of the IRS device sending a broadcast message through two MAC entities is described, including:

[0214] Step 901: The base station receives the message sent by the IRS device and sends downlink information to the IRS device through the air interface.

[0215] Here, the downlink information corresponds to the third information, that is, the broadcast message.

[0216] Step 902: The fourth PHY entity (denoted as IRS-UE-PHY) of the IRS device parses the broadcast message to obtain MIB or SIB or user information, and sends the MIB or SIB or user information to the fourth MAC entity (denoted as IRS-UE-MAC).

[0217] Step 903: The fourth MAC entity (denoted as IRS-UE-MAC) of the IRS device sends the received MIB or SIB or user information to the third MAC entity (denoted as IRS-BS-MAC).

[0218] Step 904: The third MAC entity (denoted as IRS-BS-MAC) of the IRS device sends the MIB or SIB or user information to the terminal.

[0219] Here, the shaping control of the IRS device for the terminal has the following advantages:

[0220] (1) The protocol stack of the IRS device is simple, including a total of two protocol layers, MAC and PHY.

[0221] (2) The MAC layer of the IRS device is divided into two MAC entities, and the PHY layer is divided into two PHY entities, and each forms a protocol stack. Through two protocol stacks with different functions, the sending of the broadcast message is realized.

[0222] In one example, taking the first network device as an IRS device and the second network device as a base station as an example, combined with Figure 5 the protocol stack schematic diagram of the IRS device shown, as Figure 10 shown, the process of the IRS device realizing shaping control through two MAC entities is described, including:

[0223] Step 1001: The base station receives the message sent by the IRS device and sends downlink information to the IRS device through the air interface.

[0224] Step 1002: The fourth PHY entity of the IRS device (denoted as IRS-UE-PHY) sends the shaping control information to the fourth MAC entity (denoted as IRS-UE-MAC).

[0225] Step 1003: The fourth MAC entity of the IRS device (denoted as IRS-UE-MAC) sends the received shaping control information to the third MAC entity (denoted as IRS-BS-MAC).

[0226] Step 1004: The third MAC entity of the IRS device (denoted as IRS-BS-MAC) uses the received shaping control information to generate beamforming for at least one terminal; and uses the generated beamforming to control data transmission with the at least one terminal.

[0227] Here, the shaping control of the IRS device for the terminal has the following advantages:

[0228] (1) The protocol stack of the IRS device is simple, including only two protocol layers, namely MAC and PHY.

[0229] (2) The MAC layer of the IRS device is divided into two MAC entities, and the PHY layer is divided into two PHY entities, each forming a protocol stack. Through the two protocol stacks with different functions, the shaping control information sent by the base station side is used to achieve shaping control of the terminal side, thereby realizing the shaping coverage of the IRS device.

[0230] In the fourth case, the first MAC entity and the first PHY entity of the IRS device implement the function of reporting the measurement message sent by the terminal to the second network device.

[0231] In an embodiment, the method further includes:

[0232] The first PHY entity of the IRS device receives the fourth information sent by the terminal; the fourth information is measurement report information;

[0233] The first PHY entity sends the fourth information to the first MAC entity of the IRS device;

[0234] The first MAC entity uses the measurement information to determine the location information of the terminal where it is currently located, saves the location information, and sends the measurement information to the second MAC entity of the second network device.

[0235] It should be noted that here, the measurement information sent by the terminal can also be sent to the second network device through two MAC entities. The specific implementation process is similar to the process of sending the second information through two MAC entities, and will not be elaborated here.

[0236] Adopting the technical solution of the embodiment of the present invention, the protocol stack of the IRS device is simple. The protocol stack includes a MAC layer and a PHY layer. The IRS device can interact with a second network device such as a base station as a terminal to obtain control information and the like sent by the second network device, and implement functions on the base station side.
