Detailed Description

Before the technical solution of the embodiment of the present invention is introduced, a description is given of a related art.

In the related art, the research on the air vent technology is increasing. In order to implement flexible extension of air interface coverage with low power consumption, the IRS is increasingly studied. The IRS can utilize Meta-materials (Meta-materials) to control the phase of the surface in real time, and form reflected beams in different directions by controlling the reflection angle of incident waves, so that wireless signals are forwarded to other communication equipment.

Based on this, in each embodiment 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 for requesting scheduling or management of the terminal; the first MAC entity sends the first information to a second MAC entity of second network equipment; receiving 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.

It should be noted that, in the embodiment of the present invention, defining the protocol stack of the first network device to be simple has the following advantages:

(1) the protocol stack of the first network equipment only has two layers including an MAC layer and a PHY layer, and the functions of the second network equipment side can be realized through the MAC layer and the PHY layer: the first network device interacts with the second network device, such as a base station, with the identity of the terminal, obtains control information and the like sent by the second network device, and realizes functions on the terminal side: the terminal is scheduled or managed based on control information sent by a second network device, such as a base station.

(2) By defining a layer two rapid handshake scheme between first network equipment (such as IRS equipment) and second network equipment (such as a base station), compared with a traditional mode of establishing a link through a layer three, the method can realize a control mode of establishing a real-time link facing an air interface with short time delay;

(3) and the layer two quick handshake can be realized through the MAC layer and the PHY layer protocol of the layer two defined by the first network equipment (such as the IRS equipment). Specifically, through the fast control of the MAC layer, fast handshaking between the first network device and the terminal (e.g., UE), and between the first network device and the second network device (e.g., base station) is achieved, which not only can 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 the first network device (e.g., IRS device) does not have an upper link, but also can reduce the complexity of the implementation of the first network device (e.g., IRS device) and the high energy consumption caused by the heavy protocol stack.

The present invention will be described in further detail with reference to the accompanying drawings and examples.

FIG. 1 is a schematic diagram of a system architecture applied to an information processing method according to an embodiment of the present invention; as shown in fig. 1, the system includes a terminal 11, a first network device 12, a second network device 13; wherein, the first and the second end of the pipe are connected with each other,

the terminal 11 is configured to send first information to the IRS device through a second PHY entity of the terminal; the first information represents information requesting scheduling or management of the terminal.

The first network device 12, which may be an IRS device, is configured to receive, through a first PHY entity of the first network device, first information sent by a second PHY entity of a terminal, and send the first information to a first MAC entity of the IRS device; and the first MAC entity sends the first information to a second MAC entity of second network equipment.

The second network device 13 is configured to receive, by using a second MAC entity of the second network device, first information sent by a first MAC entity of the IRS device, and return second information to the first MAC entity. And the second information represents information for scheduling and managing the terminal.

The first network device 12 is further configured to schedule or manage the terminal based on the second information through a first MAC entity of the first network device.

Fig. 2 is a schematic diagram of an IRS device according to an embodiment of the present invention, and as shown in fig. 2, the IRS may refer to a novel intelligent passive surface, and may utilize Meta-materials (Meta-materials) to perform real-time control on a phase of the surface, and control a reflection angle of an incident wave, so as to form reflected beams in different directions, and further forward a wireless signal to other communication devices. Fig. 3 is a schematic diagram of an IRS device transmitting a wireless signal, and as shown in fig. 3, the IRS device can forward the wireless signal without a complex Radio Frequency (RF) circuit.

An embodiment of the present invention provides an information processing method, which is applied to an IRS device, and as shown in fig. 4, the method includes:

step 401: a first PHY entity of first network equipment 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 equipment; the first information represents information for requesting scheduling or management of the terminal;

step 402: the first MAC entity sends the first information to a second MAC entity of second network equipment; receiving second information returned by the second MAC entity based on the first information; the second information represents information for scheduling and managing the terminal;

step 403: and the first MAC entity schedules or manages the terminal based on the second information.

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

Here, in steps 402 to 403, the IRS device may perform signaling or data transfer, and further have a function of scheduling or managing the terminal based on the control information transmitted by the second network device. In order to make the implementation manner of scheduling or managing the terminal simple, the IRS device may define a protocol stack to be simple, that is, the protocol stack of the IRS device has only two layers, namely, an MAC layer and a PHY layer, and two basic functions are implemented through the MAC layer and the PHY layer: the first function is that the IRS device interacts with a second network device such as a base station by using the identity of the terminal to obtain control information sent by the second network device, and the second function is that the terminal is scheduled or managed based on the control information sent by the second network device such as the base station.

The following describes in detail the process of the first network device implementing the basic function of the protocol stack through the MAC layer and the PHY layer, taking the first network device as an IRS device as an example.

In the first case, 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 according to two basic functions implemented by the protocol stack. Therefore, the uplink message sent by the terminal is sent to the second network equipment through the two MAC entities and the two PHY entities, and the terminal is scheduled or managed based on the downlink message returned by the second network equipment.

In practical 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 may interact with each other, so that the first information sent by the terminal may be sent to the second network device through the two MAC entities.

Based on this, in one 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 sending, by the first MAC entity, the first information to a second MAC entity of a second network device includes:

the third MAC entity receives the first information sent by the second PHY entity through the third PHY entity; and sending the first information to the fourth MAC entity;

For example, fig. 3 is a schematic diagram of a protocol stack of an IRS device, and as shown in fig. 5, the protocol stack of the IRS device can be divided into two protocol stacks according to two functions implemented by the protocol stack, that is, an IRS-UE (User Equipment: terminal) protocol stack and an IRS-BS (Base Station: Base Station) protocol stack; wherein, the first and the second end of the pipe are connected with each other,

and the IRS-UE protocol stack is used for finishing the handshake, connection management and connection synchronization functions of the IRS equipment and the base station, and interacting with the base station by using the identity of the terminal, so that the IRS-UE protocol stack is called as IRS-UE.

The IRS-BS protocol stack is used for scheduling or managing the terminal under the control of the base station, for example, implementing the beamforming function of the terminal, transmitting uplink and downlink data between the UE and the base station, and providing an air interface service to the user, and is called as an IRB-BS.

Here, the IRS-BS protocol stack includes two parts, a third MAC entity (denoted by IRS-BS-MAC) and a third PHY entity (denoted by IRS-BS-PHY); wherein the content of the first and second substances,

and the IRS-BS-MAC represents an MAC protocol in an IRS-BS protocol stack and is used for managing the UE in the IRS coverage range, and has the functions of identity identification information, UE position information, air interface signal shaping information, measurement processing reported by the UE and the like. The scheduling or management function (denoted as NB-MAC) of the MAC in the entity and the base station for the UE is a peer-to-peer protocol function entity, which is an extension of the NB-MAC function.

The IRS-BS-PHY represents a PHY protocol in an IRS-BS protocol stack and is used for receiving and sending an air interface signal of the UE in the IRS coverage range, and comprises functions of beamforming, beamforming re-shaping or beamforming modification of the UE.

Here, the IRS-UE protocol stack includes two parts, a fourth MAC entity (denoted by IRS-UE-MAC) and a fourth PHY entity (denoted by IRS-UE-PHY); wherein, the first and the second end of the pipe are connected with each other,

the IRS-UE-MAC represents the MAC protocol in the IRS-UE protocol stack and is used for completing the establishment, modification, maintenance and release of the connection with the base station and controlling and measuring reporting functions aiming at the IRS Panel. The function (denoted as NB-MAC) of the MAC layer of the entity and the base station responsible for IRS connection management is a peer-to-peer protocol function entity.

And the IRS-UE-PHY represents a PHY protocol in an IRS-UE protocol stack and is used for processing the physical signal interacted between the IRS and the base station. The function (denoted as NB-PHY) of this entity responsible for IRS connection management with the PHY layer of the base station is a peer-to-peer protocol function entity.

In practical application, after the first MAC entity of the IRS device is divided into two MAC entities according to two functions implemented by the protocol stack, the two MAC entities may interact with each other to control the terminal to complete a random access procedure, or, the two MAC entities may perform a data packet to control uplink and downlink data transmission of the terminal.

Based on this, in an embodiment, the sending the first information to the fourth MAC entity includes one of:

For example, as shown in fig. 5, the third MAC entity (denoted by IRS-BS-MAC) of the IRS-BS protocol stack receives the first information transmitted by the second PHY entity of the terminal through the third PHY entity (denoted by IRS-BS-PHY); and sending the first information to a fourth MAC entity (denoted by IRS-UE-MAC) of the IRS-UE protocol stack, so that the interaction of the data packet of the user or the user context request information can be completed between the IRS-UE-MAC and the IRS-BS-MAC.

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

Based on this, in an embodiment, the sending the first information to the second MAC entity includes one of:

For example, as shown in fig. 5, a 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).

In practical application, after the first MAC entity of the IRS device is divided into two MAC entities according to 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.

Based on this, in an embodiment, the receiving the second information returned by the second MAC entity based on the first information includes:

In practical application, after the first MAC entity of the IRS device is divided into two MAC entities according to two functions implemented by the protocol stack, the MAC entity responsible for interacting with the second network device may send the downlink message sent by the second network device to the other MAC entity.

Based on this, in an embodiment, the fourth MAC entity receives second information returned by the second MAC entity based on the first information, and sends the second information to the third MAC entity, where the second information includes one of:

For example, as shown in fig. 5, a fourth MAC entity (denoted by IRS-UE-MAC) of the IRS-UE protocol stack receives second information returned by the second network device based on the first information, and sends the second information to a third MAC entity (denoted by IRS-BS-MAC) of the IRS-BS protocol stack, so that the interaction between the IRS-UE-MAC and the IRS-BS-MAC can be completed in the downlink direction.

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

Based on this, in an embodiment, the first MAC entity schedules or manages the terminal based on the second information, which includes one of:

The following describes in detail an implementation process of the information processing method according to the embodiment of the present invention with reference to a specific embodiment.

In an example, taking a first network device as an IRS device as an example, and referring to a schematic diagram of a protocol stack of the IRS device shown in fig. 5, as shown in fig. 6, a process of the IRS device controlling a random access procedure of a terminal through two MAC entities is described, including:

step 601: and the terminal sends an uplink Message (UL Message) to the IRS equipment through an air interface.

Here, the uplink message corresponds to the first information.

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

Step 603: after the third MAC entity (denoted by IRS-BS-MAC) of the IRS device receives the decoded message sent by the third PHY entity (denoted by IRS-BS-PHY), if the received message is Random Access (RA) information, UE context request information is generated and sent to the fourth MAC entity (denoted by IRS-UE-MAC).

Step 604: after receiving the message sent by the IRS-BS-MAC, the fourth MAC entity (denoted by IRS-UE-MAC) of the IRS device constructs a MAC PDU carrying the context request information and sends the MAC PDU to the fourth PHY entity (denoted by IRS-UE-PHY).

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

Step 606: and the base station receives the context request information sent by the IRS equipment and sends downlink information to the IRS equipment through an air interface.

Here, the downlink information is the second information, i.e., New context information (New ID) of the UE.

Step 607: the fourth PHY entity (denoted IRS-UE-PHY) of the IRS device transmits the generated new context information to the fourth MAC entity (denoted IRS-UE-MAC) in the form of a MAC PDU.

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

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

Step 609: and the third MAC entity (represented by IRS-BS-MAC) of the IRS device utilizes the received new context information to control the terminal to complete the random access process.

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

(1) defining a simple protocol stack of an IRS system, wherein the protocol stack comprises two protocol layers including an MAC (media access control) layer and a PHY (physical layer), and can complete the following functions on the basis of realizing a low-complexity protocol stack function scheme: handshake flow with base station and synchronous hold function; and according to the control information of the base station, sending a proper beam to the specified UE, namely the IRS has the autonomous forming capability. By peer-to-peer definition of the protocol functions of the three functional entities of the base station, the IRS and the terminal, the consistency design of the protocol functions of the three functional entities is realized on the premise of ensuring the functions from the IRS to the simple protocol stack.

(2) The MAC layer of the IRS equipment is divided into two MAC entities, the PHY layer is divided into two PHY entities, each PHY entity forms a protocol stack, and the functions of the base station side are realized through the two protocol stacks with different functions: the IRS device interacts with a second network device such as a base station by using the identity of the terminal, sends first information sent by the terminal to the second network device, receives control information sent by the second network device, and has the functions of the terminal side: the terminal is scheduled or managed based on control information sent by a second network device, such as a base station.

(3) The two MAC entities can realize the interaction with the terminal and the base station;

(4) the MAC entity supports the quick access of the terminal, and realizes the function of plug and play.

In an example, taking a first network device as an IRS device as an example, and referring to a protocol stack schematic diagram of the IRS device shown in fig. 5, as shown in fig. 7, a process that the IRS device implements control over data transmission of a terminal through two MAC entities is described, including:

step 701: and the terminal sends an uplink Message (UL Message) to the IRS equipment through an air interface.

Here, the uplink message corresponds to the first information.

Step 702: a third PHY entity (represented by IRS-BS-PHY) of the IRS device receives the uplink message sent by the UE, decodes the received uplink message to obtain a decoded message, and sends the decoded message to a third MAC entity (IRS-BS-MAC).

Step 703: after receiving the decoded message sent by the third PHY entity (denoted by IRS-BS-PHY), the third MAC entity (denoted by IRS-BS-MAC) of the IRS device directly sends the received message to the fourth MAC entity (denoted by IRS-UE-MAC) if the received message is uplink data.
