Detailed Description
The present application will be described in further detail with reference to the following drawings and examples.
In order to realize the coverage range of the 6G system for expanding wireless communication, the application of IRS in the 6G system is proposed. As shown in fig. 2, signal transmission between the base station and the terminal is blocked at an obstacle such as a tree, so that a link h is formeddWhen the uplink signal becomes weak, the base station may communicate with the terminal through an IRS Access Point (which may be referred to as AP for short), that is, in the downlink, the terminal may directly receive the downlink signal through the IRS Access Point, and in the uplink, the base station may receive the uplink signal through the IRS Access Point. Wherein the terminal communicates with the base station via the IRS access point via a channel (which may also be understood as a link) (this channel comprises channel f shown in fig. 2rAnd the channel between the IRS access point and the terminal) and the channel in which the terminal receives the downlink signal directly from the base station (i.e., the link h shown in fig. 2)d) In contrast, the channel through which the terminal communicates with the base station via the IRS access point increases the channel between the base station and the IRS access point (i.e., channel f shown in FIG. 2) as compared to the channel through which the terminal receives downlink signals directly from the base stationr)。
Based on the application scenario of signal transmission through the IRS access point shown in fig. 2, it is considered that the IRS access point is used to implement flexible extension of existing wireless communication coverage, so as to enhance coverage signals and solve the problem of coverage blind areas such as "dark under tower". In order to improve the signal transmission efficiency, the IRS needs to accurately transmit a radio signal when performing signal transmission through the IRS access point.
Based on this, in various embodiments of the present application, the network device controls the at least one IRS access point to provide services for the terminal, so that the at least one IRS access point can accurately send the wireless signal under the control of the network device, thereby improving the transmission efficiency of the wireless signal and further achieving flexible extension of the wireless communication coverage.
An embodiment of the present application provides a service control method, which is applied to a network device, and as shown in fig. 3, the method includes:
step 301: establishing a connection with at least one IRS access point;
step 302: controlling at least one IRS access point to provide service for the terminal;
here, the network device can provide a service to the terminal.
In practical applications, the IRS Access point may be understood as an intelligent reflective antenna, and besides the antenna unit, the IRS Access point may further include protocol stack functional blocks such as a Media Access Control (MAC) layer, a PHYsical (PHY) layer, and the like, so as to implement interaction with the network device. Of course, the specific structure of the IRS access point may also be set according to the requirement, which is not limited in this embodiment of the application.
In step 301, during actual application, the IRS access point may be set to automatically search for a network device (specifically, a base station) after being powered on, and access the network device when the network device is searched, so as to establish a connection with the network device. Of course, the manner in which the network device establishes the connection with the IRS access point may also be set according to requirements, which is not limited in this embodiment of the present application.
In step 302, in actual application, the service may also be understood as transmission and reception of signals; specifically, the network device controls at least one IRS access point to provide a service for the terminal, which may be understood as the network device controlling at least one IRS access point to send a signal to the terminal; and/or the network device controls at least one IRS access point to receive signals from the terminal.
In step 302, the network device connects with at least one IPR access point that is controlled.
Here, in an embodiment, the controlling at least one IRS access point to provide services for the terminal may include at least one of:
controlling at least one IRS access point to transmit a common signal;
controlling at least one IRS access point to provide service for the terminal in the first area;
controlling at least one IRS access point to provide service for a first terminal;
controlling at least one IRS access point to serve terminals of the first group of users.
Wherein the controlling at least one IRS access point to transmit a common signal may include: controlling at least one IRS access point to broadcast, page, etc. signal coverage of common channels not targeted for a particular terminal. In practical application, the specific type of the common signal may be set according to requirements, and the embodiment of the present application does not limit this.
The controlling at least one IRS access point to provide service for the terminal in the first area may include: controlling at least one IRS access point to send signals to terminals in a first area (specifically, a cell); and/or, controlling at least one IRS access point to receive signals from terminals of the first area. By controlling at least one IRS access point to serve the terminals of the first area, enhancement of the signal coverage of the first area, such as blind compensation, hot compensation, and extension of the signal coverage of the first area, can be achieved.
The controlling at least one IRS access point to provide service for the first terminal may include: controlling at least one IRS access point to send signals to a first terminal; and/or control at least one IRS access point to receive signals from the first terminal. For example, as shown in fig. 4, when a network device (specifically, a base station) controls at least one IRS access point to provide a service for the first terminal, an air interface access point serving the first terminal includes both the base station and the at least one IRS access point.
The at least one IRS access point is controlled to provide service for the terminals of the first user group, that is, the at least one IRS access point is controlled to perform multicast aiming at the terminals of the first user group; the multicast may include multicast of control information and/or multicast of data; i.e. the network device may control at least one IRS access point to send unified (i.e. identical) control information and/or data to the terminals of the first user group.
Wherein the first group of users is formed under control of the network device. That is, each terminal in the first user group is formed into a group under the control of the network device.
In practical application, the manner in which the network device controls at least one IRS access point may include: the way in which the IRS access point is invisible to the terminal and the way in which the IRS access point is visible to the terminal.
Wherein, the IRS access point being invisible to the terminal means: the terminal cannot obtain information about the IRS access point it is serving. At this time, the network device needs to determine a link budget according to the measurement information fed back by the terminal, determine configuration information such as power, a forming coefficient, resource allocation, and available time-frequency domain resources for the terminal to transmit an uplink signal and receive a downlink signal, and transmit the link budget and the configuration information to the terminal through the IRS access point, or schedule the terminal according to the determined configuration information, and the terminal only needs to receive or transmit data (i.e., signals) according to a scheduling instruction of the network device. Here, the link includes a link between the network device and the IRS access point and a link between the IRS access point and the terminal.
Accordingly, the IRS access point being visible to the terminal means: the terminal can obtain information about the IRS access point it is serving. At this time, since the network device needs to determine the link budget by using the measurement information fed back by the terminal, and there is a certain time delay when the terminal feeds back the measurement information to the network device, in order to avoid the problem of inaccurate link budget caused by the time delay, the network device and the terminal may be set to synchronously calculate the link overhead between the IRS access point and the network device, and the terminal may be set to report the link overhead determined by the terminal to the network device every preset time (which may be set according to the requirement, for example, 5 minutes), so that the network device may calibrate the link overhead determined by the terminal.
In practical application, the specific content of the link budget can be set according to requirements, such as link synchronization compensation and differentiated control of information receiving and information sending on the link; for another example, the total power of the whole link (i.e., the link between the network device and the IRS access point and the link between the IRS access point and the terminal) is distributed, and then the total power is divided into each link (i.e., the communication device).
In practical application, in the process that the network device controls at least one IRS access point in a manner that the IRS access point is invisible to the terminal, when downlink signal transmission is performed for a target terminal, the network device may configure synchronization supplementary information corresponding to each IRS access point in all IRS access points serving the target terminal to the target terminal, and when the target terminal receives the downlink signal, the target terminal may perform signal synchronization compensation according to the synchronization supplementary information; specifically, the target terminal may perform compensation and equalization of signals at each antenna port according to the synchronization supplementary information in a signal processing process, and perform signal combination; or, the target terminal may perform signal processing corresponding to each antenna port signal, and perform coding combination during decoding. Here, a manner in which the network device configures the synchronization supplementary Information to the target terminal may also be set according to a requirement, for example, Downlink Control Information (DCI) carried by Radio Resource Control (RRC) signaling, a MAC Control Element (CE), or a Physical Downlink Control Channel (PDCCH) may send the synchronization supplementary Information to the target terminal.
In addition, in the process that the network device controls at least one IRS access point in a manner that the IRS access point is invisible to the terminal, when controlling the transmission of the uplink signal, the network device may schedule an uplink IRS access point link available to the corresponding terminal and a beam characteristic received by the corresponding IRS access point, and perform link compensation, combination, and equalization after receiving the terminal uplink signal collected and forwarded by each IRS access point. Specifically, since the IRS access point is invisible to the terminal, the network device can determine information such as the position of the terminal, the strength of the received signal, and the position of the terminal relative to the IRS access point according to the measurement report information of the terminal, thereby determining the beam characteristics of the terminal; the change of the IRS access point serving for the terminal can be determined according to the change of the movement of the terminal, and an uplink IRS access point link available for the terminal and the beam characteristics received by the corresponding IRS access point are scheduled; finally, the network device may perform link compensation, merging, and equalization after receiving the signals of the terminals collected by each IRS access point. Here, in the case that the terminal moves slowly, the network device may schedule one or more IRS access points at a time to serve the terminal for a preset duration (which may be set according to requirements, such as 5 milliseconds, 10 milliseconds, and the like); in the case that the terminal moves fast, the network device may perform dynamic scheduling on the IRS access point.
Based on this, in an embodiment, when the network device controls at least one IRS access point in a manner that the IRS access point is invisible to the terminal, the method may further include:
configuring the terminal with synchronization information of at least one IRS access point link for providing service for the terminal; the synchronization information is used for the terminal to receive signals.
In practical application, in the process that the network device controls at least one IRS access point in a manner that the IRS access point is visible to the terminal, the terminal can obtain the relevant information of the IRS access point serving the terminal, and therefore, the network device can configure the TA of the IRS access point serving the corresponding terminal to the corresponding terminal, so that the corresponding terminal can maintain uplink synchronization with each IRS access point.
Based on this, in an embodiment, when the network device controls at least one IRS access point in a manner that the IRS access point is visible to the terminal, the method may further include:
configuring the terminal as a TA of at least one IRS access point link serving the terminal.
Here, the manner in which the network device configures the TA of the corresponding IRS access point link for the terminal may be set according to requirements, for example, the TA configuration information is sent to the terminal through the RRC signaling, the MAC CE, or the DCI carried by the PDCCH. For example, during the moving of the terminal, the terminal may perform cell handover, and at this time, the target network device after cell handover may configure a TA command word of the terminal through a TA MAC CE, instruct the terminal to perform uplink synchronization adjustment, and implement that the terminal and each IRS access point serving the terminal maintain uplink synchronization.
In practical application, when the network device controls at least one IRS access point in a manner that the IRS access point is invisible to the terminal or the IRS access point is visible to the terminal, in order to further improve efficiency of information transmission by the IRS access point, the link budget may include Beamforming (english may be denoted as Beamforming).
Based on this, in an embodiment, the method may further include:
controlling beamforming of at least one IRS access point serving at least one terminal.
Here, the network device may control the IRS access point in a manner that the IRS access point is invisible to the terminal, or may control the IRS access point in a manner that the IRS access point is visible to the terminal.
In practical application, the network device may control beamforming of at least one IRS access point serving at least one terminal based on measurement information characterizing a location of the terminal reported by the terminal through the IRS access point.
Based on this, in an embodiment, the controlling beamforming of at least one IRS access point serving at least one terminal may include:
acquiring first measurement information; the first measurement information represents the position of the terminal;
controlling beamforming of at least one IRS access point serving the at least one terminal based on the first measurement information.
In practical applications, the controlling beamforming of at least one IRS access point serving the at least one terminal based on the first measurement information may include: determining a position of the at least one IRS access point relative to the network device based on a Beam (in english may be denoted as Beam) angle of the received first measurement information, and performing beamforming between the network device and the IRS access point based on the position of the at least one IRS access point relative to the network device; meanwhile, based on the first measurement information, determining a position of the at least one IRS access point relative to the at least one terminal, and then based on the position of the at least one IRS access point relative to the at least one terminal, determining a direction angle of an antenna unit included in each IRS access point of the at least one IRS access point and a beamforming factor of a beam transmitted on the antenna unit; and sending configuration information including the direction angle of the corresponding antenna unit and the forming factor of the beam sent by the corresponding antenna unit to the corresponding IRS access point so that the corresponding IRS access point can adjust the angle of the beam sent by the antenna unit according to the direction angle of the corresponding antenna unit and the forming factor of the beam sent by the corresponding antenna unit, thereby realizing beam forming with the terminal.
In practical application, the first measurement information may include information that can represent the position of the terminal relative to the IRS access point, such as the strength of a signal received by the terminal from the IRS access point, and may be specifically set according to a requirement.
In practical application, when the network device controls the multiple IRS access points to provide services for the terminal in a manner that the IRS access points are invisible to the terminal or in a manner that the IRS access points are visible to the terminal, in order to avoid mutual interference between air interface signals caused by the multiple IRS access points, it is ensured that the network device can accurately control the IRS access points, and the network device may perform interference suppression or interference coordination on signals of the multiple IRS access points covering the same area (for example, the first area), and perform interference suppression or interference coordination on signals of the multiple IRS access points serving the same terminal (for example, the first terminal). Here, a method of performing interference suppression or interference coordination on a signal may be set according to a requirement, and for example, the network device may implement interference coordination of the signal by using an enhanced Coordinated multipoint transmission technology (CoMP), so as to improve receiving efficiency and sending efficiency of an air interface signal.
In practical application, the terminal may be in a moving state, at this time, the IRS access point providing the service for the terminal may change, and in order to further improve the accuracy of the network device in controlling the IRS access point, the network device may further perform simulation, modeling, and constraint on the behavior of the terminal based on the first measurement information to predict the moving direction of the terminal, and further determine the IRS access point providing the service for the corresponding terminal based on the predicted moving direction of the terminal.
Based on this, in an embodiment, the first measurement information may characterize a location of the terminal relative to the IRS access point; the acquiring of the first measurement information may include:
the method comprises the steps of obtaining first measurement information reported by a terminal.
In an embodiment, the first measurement information may include at least one of:
the direction angle of the terminal relative to the IRS access point;
position Reference Signal (english may be expressed as Position Reference Signal, abbreviated as Position RS);
reference signals for beamforming.
In practical application, the network device may simulate and model a position of the at least one IRS access point relative to the terminal and a beam control manner for the at least one IRS access point by using an Artificial Intelligence (AI) technique and/or a Digital Twin (DT) technique based on the first measurement information, and generate a more accurate control signaling for the at least one IRS access point according to a simulation and modeling result, thereby more accurately controlling the at least one IRS access point to provide a service for the terminal. When the terminal is in a moving state, the behavior of the terminal can also be simulated, modeled and constrained by using an AI technology and a DT technology to predict the moving direction of the terminal, and then an IRS access point for providing service for the corresponding terminal is determined based on the predicted moving direction of the terminal.
In practical application, in order to avoid the problem of signal interference caused by the fact that the IRS access point freely transmits signals, the accuracy of controlling the IRS access point by the network device is further improved, the network device can determine the IRS access point which needs to provide service for the terminal and the IRS access point which does not need to provide service for the terminal according to the information such as the requirement of one or a group of terminals which need to be served, the number of the IRS access points of the area where the corresponding terminal is located, the signal coverage strength and capacity of the corresponding cell, and the like, open the IRS access point which needs to provide service for the terminal, and close the IRS access point which does not need to provide service for the terminal.
Based on this, in an embodiment, the method may further include:
and controlling the opening of the IRS access points so as to control at least one IRS access point to provide service for the terminal.
Here, turning on an IRS access point may be understood as allowing the IRS access point to receive and transmit signals, i.e. to enable the IRS access point; and turning off the IRS access point is understood as prohibiting the IRS access point from receiving and transmitting signals.
Correspondingly, an embodiment of the present application further provides a service control method, which is applied to a terminal, and as shown in fig. 5, the method includes:
step 501: determining first measurement information;
here, the first measurement information characterizes a position of the terminal relative to an IRS access point;
step 502: reporting first measurement information;
here, the first measurement information is used for a network side to control beamforming of at least one IRS access point serving the terminal.
In step 501, during actual application, the mode of determining the first measurement information by the terminal may be set according to requirements, that is, the terminal may measure its own position according to a preset mode.
In an embodiment, the first measurement information may include at least one of:
