Description

Technical Field

[0001] Embodiments of the present application relate to the field of communications, and in particular, to a beam alignment method, an information transmission method, and related equipment. Background Art

[0002] Due to the large path loss in millimeter wave communications, narrow beam antennas are usually used to increase directional gain to compensate for the loss in the propagation path. When the narrow beam antenna's transmit and receive beams are aligned, the system will obtain the highest antenna gain and achieve optimal transmission performance. And because the terminal device is mobile, it can also periodically scan the beam while transmitting service data, and select and feedback the optimal beam on the receiver side to achieve tracking of the transmit beam. The receive beam also needs to be traversed again after the transmit beam is adjusted to the optimal one to obtain the optimal receive beam, so that the entire transmit and receive link can achieve optimal performance.

[0003] At present, in the millimeter wave WIFI beam alignment, the access point (AP) device will periodically send downlink scanning frames. The different time slots of the scanning frame are composed of signal segments pointed by different beams, so that omnidirectional beam scanning can be performed. The station (STA) is a terminal device connected to the millimeter wave WIFI. The STA obtains the transmission signals in different directions by receiving signal frames in different time periods, and then feeds back the receiving signal-to-noise ratio in different directions to the AP device to obtain the rough direction of downlink transmission. After the coarse alignment is completed, a narrower beam scan is performed on the coarse alignment direction to determine the precise downlink transmission direction. Finally, the STA searches for the uplink transmission direction according to the same scanning mechanism as the downlink, thereby completing the transceiver beam alignment.

[0004] However, continuous tracking requires a large amount of time slots for scanning and alignment, which reduces the maximum bandwidth. When tracking is slow, beam misalignment problems may occur. Secondly, in a scenario with multiple access point devices, the access point device to be switched needs to be re-initialized for search, which will cause service interruption, thereby reducing the accuracy and efficiency of beam alignment. Summary of the invention

[0005] The embodiments of the present application provide a beam alignment method, an information transmission method and related equipment, which are used to improve the accuracy and efficiency of beam alignment.

[0006] In a first aspect, the present application provides a beam alignment method. The method may be executed by an access point device, or may be executed by a chip configured in the access point device, and the present application does not limit this. The method includes: the access point device receives a first message, and then determines first beam information pointing to a target terminal device according to the first message, and then aligns the antenna beam of the access point device to the target terminal device according to the first beam information.

[0007] In this implementation, the first beam information pointing to the target terminal device is determined by the first message, and there is no need to spend a large number of time slots for scanning and alignment, thereby ensuring the maximum bandwidth, and the beam information pointing to the target terminal device is accurate even when tracking is slow, thereby improving the accuracy of beam alignment. Secondly, in a scenario with multiple access point devices, there is no need to re-initialize the search when switching access point devices, and the first beam information obtained is directed to the target terminal device, so it will not affect the business services of the target terminal device, thereby improving the efficiency of beam alignment.

[0008] In an optional implementation of the present application, the first message includes location information of the terminal device, so the access point device can determine the first beam information according to the location information of the terminal device, the location information of the access point device, and the reference beam direction information of the antenna of the access point device.

[0009] In this implementation, the access point device can determine the first beam information through its own calculations using the location information of the terminal device included in the first message, thereby improving the feasibility of this solution.

[0010] In an optional implementation of the present application, the reference beam direction information of the antenna of the access point device includes any one of normal direction information of the antenna of the access point device, or normal direction information perpendicular to the antenna of the access point device, or direction information at a preset angle to the normal of the antenna of the access point device.

[0011] In this implementation, the access point device can flexibly determine the required reference beam direction information according to actual conditions through the reference beam direction information of the antennas of different access point devices, thereby improving the flexibility of determining the first beam information, thereby improving the flexibility of this solution.

[0012] In an optional implementation of the present application, the first message includes first beam information.

[0013] In this implementation, the access point device directly determines the first beam information through the first message including the first beam information without performing any calculation, thereby improving the efficiency of determining the beam information.

[0014] In an optional implementation manner of the present application, the access point device may further send a second message to the target terminal device, so that the target terminal device determines the second beam information pointing to the access point device according to the second message.

[0015] In this implementation, the access point device sends a second message to the target terminal device, so that the target terminal device determines the second beam information pointing to the access point device according to the second message, thereby completing the mutual beam alignment between the target terminal device and the access point device, thereby improving the feasibility of beam alignment of this scheme.

Thus, the second message includes the determined second beam information.

[0017] In this embodiment, the access point device obtains the second beam information of the target terminal device pointing to the access point device through calculation, and carries the second beam information in the second message so that the target terminal device can directly determine the second beam information, thereby improving the efficiency of determining the beam information.

[0018] In an optional embodiment of the present application, the reference beam direction information of the antenna of the terminal device includes the normal direction information of the antenna of the terminal device, or the normal direction information perpendicular to the antenna of the terminal device, or any one of the direction information at a preset angle with the normal of the antenna of the terminal device.

The method includes: the terminal device receives a second message, and then determines second beam information pointing to a target access point device according to the second message, and then aligns the antenna beam of the terminal device to the target access point device according to the second beam information.

[0023] In this implementation, the second beam information pointing to the target access point device is determined by the second message, and the beam information pointing to the target access point device is accurate even when the tracking is slow, thereby improving the accuracy of beam alignment. Secondly, in a scenario with multiple access point devices, when the terminal device needs to switch access point devices when moving, since the second beam information obtained by the terminal device is directed to the target access point device providing the service, the terminal device performs normal business services, thereby improving the efficiency of beam alignment.

[0029] In this implementation, the access point device directly determines the second beam information through the second message including the second beam information without performing any calculation, thereby improving the efficiency of determining the beam information.

[0030] In an optional implementation manner of the present application, the terminal device sends a first message to the target access point device, so that the target access point device determines first beam information pointing to the terminal device according to the first message.

[0031] In this implementation, the terminal device sends a first message to the target access point device, so that the target access point device determines the first beam information pointing to the terminal device according to the first message, thereby completing the mutual beam alignment between the target access point device and the terminal device, thereby improving the feasibility of the beam alignment of this solution.

[0032] In an optional implementation of the present application, the second message includes location information of the target access point device and reference beam direction information of the antenna of the target access point device. Therefore, the terminal device can determine the first beam information based on the location information of the terminal device, the location information of the target access point device, and the reference beam direction information of the antenna of the target access point device, and the first message sent to the target access point device includes the first beam information.

[0039] In this embodiment, the location service device can enable the target access point device to determine the first beam information pointing to the target terminal device through the first message and the second message, and enable the target terminal device to determine the second beam information pointing to the target access point device. Therefore, when the tracking is slow, the target terminal device and the target access point device can obtain accurate beam information, thereby improving the accuracy of beam alignment. Secondly, in the scenario of multiple access point devices, there is no need to re-initialize the search when switching the access point device. The mutual beam alignment between the target access point device and the terminal device can be completed through the determined beam information.

[0135] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0136] The technical solution of the embodiment of the present application can be applied to various communication systems, such as millimeter wave WIFI system or long term evolution (LTE) system. With the continuous development of communication systems, the technical solution of the present application can be applied to the fifth generation (5th generation, 5G) system or new radio (new radio, NR), and can also be applied to future networks, such as 6G system or even future system; or it can also be used for device to device (D2D) system, machine to machine (M2M) system, etc.

[0137] It should be understood that the access point device in the communication system can be any device with wireless transceiver function or a chip that can be set in the device. The device includes but is not limited to: evolved Node B (eNB), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), Home base station (for example, Home evolved NodeB, or Home Node B, HNB), Base Band Unit (BBU), AP in WIFI system, wireless relay node, wireless backhaul node, transmission point (TP) or transmission receiving point (TRP), etc., and can also be a device used in 5G, 6G or even future systems, such as NR, gNB in ​​the system, or, transmission point (TRP or TP), one or a group of (including multiple antenna panels) antenna panels of a base station in a 5G system, or, it can also be a network node constituting a gNB or a transmission point, such as a baseband unit (BBU), or, a distributed unit (distributed unit). unit, DU), or picocell, or femtocell, or vehicle to everything (V2X) or road side unit (RSU) in intelligent driving scenarios, etc.

[0138] In some deployments, the gNB may include a centralized unit (CU) and a DU. The gNB may also include a radio unit (RU). The CU implements some functions of the gNB, and the DU implements some functions of the gNB, for example, the CU implements the functions of the radio resource control (RRC) layer and the packet data convergence protocol (PDCP) layer, and the DU implements the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical layer (PHY). Since the information of the RRC layer will eventually become the information of the PHY layer, or be converted from the information of the PHY layer, under this architecture, high-level signaling, such as RRC layer signaling or PHCP layer signaling, can also be considered to be sent by the DU, or by the DU+RU. It can be understood that the access point device can be a CU node, a DU node, or a device including a CU node and a DU node. In addition, the CU may be classified as an access point device in the access network RAN, or the CU may be classified as an access point device in the core network CN, which is not limited here.

[0141] It should also be understood that if applied to a millimeter wave WIFI system, the STA in the system is a terminal device connected to the millimeter wave WIFI, and the terminal device can also be called user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device.

[0142] In addition, in order to facilitate understanding of the embodiments of the present application, the following points are explained.

[0143] First, in this application, for the convenience of description, when it comes to numbering, it can be numbered continuously starting from 0. For example, the 0th symbol in a time slot can refer to the first symbol of the time slot. Of course, the specific implementation is not limited to this. For example, it can also be numbered continuously starting from 1. For example, the 1st symbol in a time slot can also refer to the first symbol of the time slot. Due to different starting values ​​of the numbering, the same symbol has different numbers corresponding to it in the time slot.

[0144] It should be understood that the above descriptions are all arrangements made to facilitate the description of the technical solutions provided in the embodiments of the present application, and are not intended to limit the scope of the present application.

[0145] Second, in the embodiments shown below, for a technical feature, the technical features in the technical feature are distinguished by "first", "second", "third", etc., and there is no order of precedence or size between the technical features described by the "first", "second", and "third".

[0146] Third, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c. Where a, b and c can be single or multiple, respectively.

In addition, combinations of these schemes may also be used.

[0149] Sixth, in the embodiments disclosed in the present application, the terms “of”, “relevant” and “corresponding” may sometimes be used interchangeably. It should be noted that when the distinction between them is not emphasized, the meanings they intend to express are consistent.

[0150] Due to the large path loss in millimeter wave communications, narrow beam antennas are usually used to increase directional gain to compensate for the loss in the propagation path. Figure 1 , Figure 1 FIG. 1 is a schematic diagram of an embodiment of beam alignment of a transmitting and receiving antenna in an embodiment of the present application. Figure 1As shown, when the narrow beam antenna of the terminal device pointing to the access point device is aligned with the narrow beam antenna of the access point device pointing to the terminal device, the system will obtain the highest antenna gain and achieve optimal transmission performance. However, due to the movement of the terminal device, the antenna beam will be deflected, which will greatly reduce the signal transmission quality and affect the link transmission performance. To solve this problem, it is usually necessary to perform beam scanning periodically while transmitting business data, and to select and feedback the optimal beam on the receiver side to achieve tracking of the transmit beam. The receive beam also needs to be traversed again after the transmit beam is adjusted to the optimal one to obtain the optimal receive beam, so that the entire transmit and receive link can achieve the best performance. In addition, when this embodiment is applied to the millimeter wave communication scenario of a home network, please refer to Figure 2 , Figure 2 FIG. 1 is a schematic diagram of an embodiment of a millimeter wave communication scenario applied to a home network in an embodiment of the present application. Figure 2 As shown, A1 indicates a terminal device, A2 to A5 indicate rooms, and access point device A can establish a connection with a terminal device in room A2, access point device B can establish a connection with terminal devices in rooms A3 and A4, and access point device C can establish a connection with a terminal device in room A5. Due to the characteristic that millimeter waves cannot penetrate walls, when a terminal device moves between rooms, for example, when the terminal device moves from the current room A2 to room A5, the link between access point device A in room A2 and the terminal device will be interrupted, while the connection between access point device C in room A5 and the terminal device has not yet been established. At this time, a long registration process and a new beam alignment process will be experienced between access point device C and the terminal device, thereby affecting the provision of services to the terminal device and reducing the service quality.

[0151] At present, in the millimeter wave WIFI beam alignment, the AP device will periodically send downlink scanning frames. The different time slots of the scanning frame are spliced ​​by signal segments pointed by different beams, so that omnidirectional beam scanning can be performed. STA is a terminal device connected to the millimeter wave WIFI. STA obtains transmission signals in different directions by receiving signal frames in different time periods, and then feeds back the received signal-to-noise ratios in different directions to the AP device, thereby obtaining the rough direction of downlink transmission. After the coarse alignment is completed, a narrower beam scan is performed on the coarse alignment direction to determine the precise downlink transmission direction. Finally, the STA searches for the uplink transmission direction according to the same scanning mechanism as the downlink, thereby completing the transceiver beam alignment. However, a large number of time slots are required for scanning and alignment in continuous tracking, which reduces the limit bandwidth. When the tracking is slow, beam misalignment problems will occur. Secondly, in the scenario of multiple access point devices, the access point device to be switched needs to be re-initialized for search, which will cause service interruption, thereby reducing the accuracy of beam alignment and reducing the efficiency of beam alignment.

[0152] In order to solve the above problems, the embodiments of the present application provide a beam alignment method and an information transmission method, which are used to improve the accuracy of beam alignment and improve the efficiency of beam alignment. Secondly, in order to better understand the beam alignment method, information transmission method and related equipment disclosed in the embodiments of the present application, first, the system architecture of the communication system used in the embodiments of the present application is described. The present application can be used in a communication system consisting of a terminal device, a location service device and multiple access point devices, and can also be used in a communication system consisting of multiple terminal devices, multiple location service devices and multiple access point devices. Based on this, Figure 3 FIG. 1 is a schematic diagram of a system architecture of a communication system in an embodiment of the present application. Figure 3 As shown, a terminal device, a location service device and multiple access point devices form a communication system, in which the location service device and the terminal device can send a first message to any one of the access point devices 1 to 3, and the location service device and the access point devices 1 to 3 can send a second message to the terminal device. In addition, a terminal device and multiple access point devices can also form a communication system, so in the communication system, the terminal device can send a first message to any one of the access point devices 1 to 3, and the access point devices 1 to 3 can send a second message to the terminal device.

[0153] Based on this, since the first message received by the access point device can be sent by the terminal device or by the location service device, and the second message received by the terminal device can be sent by the access point device or by the location service device, the first message and the second message are sent from different devices and apparatuses respectively, and the beam alignment method used in the embodiment of the present application is described in detail below.

[0154] 1. The target access point device receives a first message sent by the location service device, and the target terminal device receives a second message sent by the location service device.

[0155] Specifically, in this embodiment, the first message may include the location information of the target terminal device, or the first message may also include the first beam information. Secondly, the second message may include the location information of the target access point device, or the second message may also include the second beam information.

[0156] Therefore, in this embodiment, the situation in which the first message and the second message include different information is further introduced and described.

[0157] (1) The first message includes first beam information, and the second message includes second beam information.

[0158] See also Figure 4 , Figure 4 FIG. 1 is a schematic diagram of an embodiment of a beam alignment method in an embodiment of the present application. Figure 4 As shown, the beam alignment method includes the following steps.

[0159] S101. A location service apparatus obtains location information of a target terminal device and reference beam direction information of an antenna of the target terminal device.

[0160] In this embodiment, for the scenario where there are multiple access point devices in the home network, when the target terminal device needs to connect to the access point device, the target terminal device can send online information using a low frequency band (e.g., 2.4GHz) or wide beam broadcast, and send the location information of the target terminal device to the location service device through wide beam broadcast, so that the location service device can obtain the location information of the target terminal device. Secondly, the location service device can also determine the location information of the target terminal device through millimeter wave positioning, or determine the location information of the target terminal device through auxiliary methods, including but not limited to infrared methods, wireless local area network (WLAN) methods, and sound methods.

[0161] It is understandable that the location service device can also receive the reference beam direction information of the antenna of the target terminal device sent by the target terminal device in a similar manner through wide beam broadcasting, or determine the reference beam direction information of the antenna of the target terminal device through millimeter wave positioning, or determine the reference beam direction information of the antenna through an auxiliary method. Specifically, the reference beam direction information of the antenna of the target terminal device includes the normal direction information of the antenna of the target terminal device, or the normal direction information perpendicular to the antenna of the target terminal device, or any one of the direction information at a preset angle with the normal of the antenna of the target terminal device.

[0162] In this embodiment, the specific manner in which the location service apparatus acquires the location information of the target terminal device and the reference beam direction information of the antenna of the target terminal device is not limited.

[0163] S102: The location service apparatus obtains location information of a target access point device and reference beam direction information of an antenna of the target access point device.

[0164] In this embodiment, in a scenario where there are multiple access point devices in a home network, since the location service has been configured through manual entry when deploying the millimeter wave communication network, the location service device can store the location information of each access point device, and can also store the reference beam direction information of the antenna of each access point device.

[0165] Furthermore, the location service device needs to obtain real-time information of each access point device, which real-time information includes traffic information of each access point device or signal strength information of each access point device, and then determine the target access point device that provides administrative services for the target terminal device from multiple access point devices based on the location information and real-time information of the target terminal device obtained in step S101, thereby obtaining the location information of the target access point device and the reference beam direction information of the antenna of the target access point device from the relevant information of the multiple access point devices manually entered.

[0166] Specifically, the reference beam direction information of the antenna of the target access point device includes any one of normal direction information of the antenna of the target access point device, or normal direction information perpendicular to the antenna of the target access point device, or direction information at a preset angle to the normal of the antenna of the target access point device.

[0167] It can be understood that in a scenario where there are multiple access point devices in a home network, in an embodiment of the present application, the location service device will convert the location information of the target terminal device and the location information of the target access point device into a home network coordinate system, thereby placing the target terminal device and the target access point device in the same plane coordinate system for ease of calculation. This should not be understood as a limitation of the present application.

[0168] S103: The location service apparatus determines first beam information according to location information of the target terminal device, location information of the target access point device, and reference beam direction information of an antenna of the target access point device.

[0169] In this embodiment, after the location service device obtains the relevant information of the target terminal device and the target access point device through step S101 and step S102, the first beam information can be determined according to the location information of the target terminal device, the location information of the target access point device, and the reference beam direction information of the antenna of the target access point device. Specifically, the first beam information includes the direction information and angle information of the antenna beam of the target access point device pointing to the target terminal device.

[0170] S104: The location service apparatus determines second beam information according to the location information of the target access point device, the location information of the target terminal device, and the reference beam direction information of the antenna of the target terminal device.

[0171] In this embodiment, after the location service device obtains the relevant information of the target terminal device and the target access point device through step S101 and step S102, the second beam information can be determined according to the location information of the target access point device, the location information of the target terminal device, and the reference beam direction information of the antenna of the target terminal device. Specifically, the second beam information includes the direction information and angle information of the antenna beam of the target terminal device pointing to the target access point device.

[0172] It is understandable that, in this embodiment, there is no necessary order between step S103 and step S104. Step S103 may be executed first, or step S104 may be executed first, or step S103 and step S104 may be executed at the same time. The specific order is not limited here.

[0173] S105: The location service apparatus sends a first message to the target access point device.

[0174] In this embodiment, the location service apparatus sends a first message to the target access point device, where the first message includes the first beam information determined in step S103.

[0175] S106. The location service device sends a second message to the target terminal device.

[0176] In this embodiment, the location service device sends a second message to the target terminal device, where the second message includes the second beam information determined in step S104.

[0177] It is understandable that, in this embodiment, there is no necessary order between step S105 and step S106. Step S105 may be executed first, or step S106 may be executed first, or step S105 and step S106 may be executed at the same time. The specific order is not limited here.

[0178] S107. The target access point device determines first beam information pointing to the target terminal device according to the first message.

[0179] In this embodiment, the target access point device directly determines the first beam information pointing to the target terminal device according to the first beam information included in the first message.

[0180] S108. The target terminal device determines second beam information pointing to the target access point device according to the second message.

[0181] In this embodiment, the target terminal device directly determines the second beam information pointing to the target access point device according to the second beam information included in the second message.

[0182] It can be understood that, in this embodiment, there is no necessary order between step S107 and step S108. Step S107 can be executed first, or step S108 can be executed first, or step S107 and step S108 can be executed at the same time. The specific order is not limited here.

[0183] S109: The target access point device aligns the antenna beam of the target access point device with the target terminal device according to the first beam information.

[0184] In this embodiment, the target access point device aligns the antenna beam of the target access point device toward the target terminal device according to the direction information and angle information of the antenna beam of the target access point device pointing toward the target terminal device included in the first beam information.

[0185] For ease of understanding, the reference beam direction information of the antenna of the target access point device is taken as the normal direction information of the antenna of the target access point device, and the direction information and angle information included in the first beam information indicate that the normal direction of the antenna of the target access point device is counterclockwise, and the antenna beam with an angle of 100° is aimed at the target terminal device as an example, see Figure 5 , Figure 5 FIG. 1 is a schematic diagram of an embodiment of the present application in which the antenna beam of the access point device is directed toward the terminal device. Figure 5 As shown, B1 indicates the antenna beam of the target access point device. The antenna beam B1 is an antenna beam whose normal direction of the antenna of the target access point device determined according to the first beam information is counterclockwise and has an angle of 100°. Therefore, the target access point device aligns the antenna beam B1 with the target terminal device.

[0186] S110: The target terminal device aligns the antenna beam of the target terminal device with the target access point device according to the second beam information.

[0187] In this embodiment, the target access point device aligns the antenna beam of the target access point device toward the target terminal device according to the direction information and angle information of the antenna beam of the target access point device pointing toward the target terminal device included in the first beam information.

[0188] For ease of understanding, the reference beam direction information of the antenna of the target terminal device is taken as the normal direction information of the antenna of the target terminal device, and the direction information and angle information included in the second beam information indicate that the normal direction of the antenna of the target terminal device is counterclockwise, and the antenna beam with an angle of 100° is aimed at the target access point device as an example, see Figure 6 , Figure 6 FIG. 1 is a schematic diagram of an embodiment of the present application in which the antenna beam of a terminal device is directed toward an access point device. Figure 6As shown, C1 indicates the antenna beam of the target terminal device. The antenna beam C1 is an antenna beam whose normal line of the antenna of the target terminal device determined according to the second beam information is counterclockwise and has an angle of 100°. Therefore, the target terminal device aligns the antenna beam C1 with the target access point device.

[0189] It can be understood that, in this embodiment, there is no necessary order between step S109 and step S1010. Step S109 can be executed first, or step S1010 can be executed first, or step S109 and step S1010 can be executed at the same time. The specific order is not limited here.

[0199] In this embodiment, the location service apparatus sends a second message to the target terminal device, where the second message includes the location information of the target access point device acquired in step S202.

[0200] It is understandable that, in this embodiment, there is no necessary order between step S203 and step S204. Step S203 may be executed first, or step S204 may be executed first, or step S203 and step S204 may be executed at the same time. The specific order is not limited here.
