Background

In a 5G New air interface (New Radio, abbreviated as NR), a system can form one or more beams with strong directivity by applying a large-scale antenna array based on beams (beams), so that the coverage area of the system can be increased and the interference can be reduced.

In a high-frequency system, if the coverage of a beam is to be ensured, a beam with a narrow width needs to be formed, and at this time, if a terminal moves, a beam switching process is frequently triggered, and system resources and overhead are occupied. There is a need to devise a solution for beam emission in high frequency systems to solve this problem.

In addition, in a large-scale antenna array, beam management is indispensable, and the system can find and maintain the optimal beam direction through the beam management, so that the performance of the system is ensured. A mode of beam management is that terminal equipment monitors relevant information of a plurality of beams and feeds back one or more good beams to a base station, the base station adjusts a transmitting beam according to the feedback of the terminal equipment, and the terminal equipment adjusts a receiving beam of the terminal equipment according to the transmitting beam, so that a connecting beam of the best beam is found.

The problem with this approach is that separate adjustment of the transmit and receive beams can greatly affect the adjustment delay.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

First, the concept to which the present application relates will be explained.

The terminal equipment: the terminal equipment can be deployed on land, including indoors or outdoors, is handheld, worn or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal device may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a vehicle-mounted terminal device, a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety, a wireless terminal in city (smart city), a wireless terminal in smart home (smart home), a wearable terminal device, and the like. The terminal device according to the embodiments of the present application may also be referred to as a terminal, a User Equipment (UE), an access terminal device, a vehicle-mounted terminal, an industrial control terminal, a UE unit, a UE station, a mobile station, a remote terminal device, a mobile device, a UE terminal device, a wireless communication device, a UE agent, or a UE apparatus. The terminal equipment may also be fixed or mobile.

A network device: generally having wireless transceiving capability, the network device may have mobile features, for example, the network device may be a mobile device. Alternatively, the network device may be a satellite, balloon station. For example, the satellite may be a Low Earth Orbit (LEO) satellite, a Medium Earth Orbit (MEO) satellite, a geosynchronous Orbit (GEO) satellite, a High Elliptic Orbit (HEO) satellite, and the like. For example, LEO satellites typically have orbital altitudes ranging from 500km to 1500km, and orbital periods (periods of rotation around the earth) of about 1.5 hours to 2 hours. The signal propagation delay of the inter-user single-hop communication is about 20ms, and the inter-user single-hop communication delay refers to the transmission delay from the terminal equipment to the network equipment or the delay from the network equipment to the transmission equipment. The maximum satellite visibility time is about 20 minutes, which is the longest time that the beam of the satellite covers a certain area of the ground, and the LEO satellite moves relative to the ground, and the ground area covered by the LEO satellite changes as the satellite moves. The LEO satellite has short signal propagation distance, less link loss and low requirement on the transmitting power of terminal equipment. The orbit altitude of GEO satellites is typically 35786km with an orbit period of 24 hours. The signal propagation delay for inter-user single-hop communications is approximately 250ms. In order to ensure the coverage of the satellite and increase the system capacity of the communication network, the satellite may cover the ground by multiple beams, for example, one satellite may form tens or hundreds of beams to cover the ground, and one beam may cover a ground area having a diameter of tens to hundreds of kilometers. Of course, the network device may also be a base station disposed on a land, a water area, or the like, for example, the network device may be a next generation base station (gNB) or a next generation evolved node b (ng-eNB). The gNB provides a user plane function and a control plane function of a New Radio (NR) for the UE, and the ng-eNB provides a user plane function and a control plane function of an evolved universal terrestrial radio access (E-UTRA) for the UE, where it should be noted that the gNB and the ng-eNB are only names used for representing a base station supporting a 5G network system, and are not limited. The network device may also be a Base Transceiver Station (BTS) in a GSM system or a CDMA system, a base station (NB) in a WCDMA system, or an evolved node B (eNB or eNodeB) in an LTE system. Alternatively, the network device may also be a relay station, an access point, an in-vehicle device, a wearable device, and a network-side device in a network after 5G or a network device in a PLMN network for future evolution, a Road Side Unit (RSU), and the like.

Wave beam: the shape of the electromagnetic wave emitted from the satellite antenna is formed on the earth surface, and the shape of the beam is determined by the satellite antenna, such as a global beam, a spot beam, and a shaped beam.

First, a suitable application scenario of the present application is introduced.

Fig. 1 is a schematic diagram of an application scenario provided in an embodiment of the present application. Referring to fig. 1, the network device 101 and the terminal device 102 are included, and wireless communication and data transmission can be performed between the network device 101 and the terminal device 102.

The Network including the Network device 101 and the terminal device 102 may also be referred to as a Non-Terrestrial communication Network (NTN), where NTN refers to a communication Network between the terminal device and a satellite (which may also be referred to as a Network device).

It can be understood that the technical solution of the embodiment of the present application can be applied to New Radio (NR) communication technology, where NR refers to a New Generation Radio access network technology, and can be applied to a future evolution network, such as the fifth Generation Mobile communication (5 g) system in the future. The scheme in the embodiment of the application can also be applied to other Wireless communication networks such as Wireless Fidelity (WIFI) and Long Term Evolution (LTE), and the corresponding names can also be replaced by names of corresponding functions in other Wireless communication networks.

The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

In 5G communication, the application of a large-scale antenna array based on beams is realized. By increasing the number of physical antennas, the system can form one or more highly directional beams. Fig. 2 is a schematic view of beam coverage provided in the embodiment of the present application, as shown in fig. 2, including a network device 21 and a terminal device 22. The network device 21 forms a beam coverage by a plurality of beams, such as beam 1, beam 2 and beam 3 illustrated in fig. 2. By forming one or more beams with strong directivity, the system coverage area is increased and the interference is reduced.

In large scale antenna array communications, beam management is essential. Through beam management, the system can find and maintain the optimal beam direction of the system, and the performance of the whole system is ensured.

In current beam management, a terminal device first detects a relevant parameter, and then feeds back one or more preferred beams to a network device according to the detected relevant parameter, where the relevant parameter detected by the terminal device may be, for example, reference signal received power, interference-plus-noise ratio, and the like. After the terminal device feeds back one or more preferred beams to the network device, the network device adjusts the transmission beam according to the feedback of the terminal device. After the network device determines the transmitting beam, the terminal device adjusts its own receiving beam according to the transmitting beam of the network device, so as to find the connecting beam of the best beam.

The main problem with the above approach to beam management is that, first, the beam coverage is narrower due to the more concentrated beam energy in high frequency scenes. When the location of the terminal device changes, the terminal device may be out of the original beam coverage, and the UE may need to switch beams quickly and frequently. For example, in the example of fig. 2, terminal device 22 is initially in position a, with terminal device 22 being in the coverage area of beam 1. When the position of the terminal device 22 moves, for example, from the a position to the B position, the terminal device 22 is not in the coverage area of the beam 1, and communication with the network device 21 through the beam 1 cannot be achieved. When the terminal device 22 moves to the B position and is within the coverage of beam 2, it needs to switch to beam 2. In practice, the position of the terminal device may change at any time, and when in a high-frequency scene, the coverage area of the beam is narrower, and the frequent switching of the beam is more obvious.

Secondly, in the beam management method, the transmitting beam of the network device and the receiving beam of the terminal device are separately adjusted, that is, firstly, the network device adjusts the transmitting beam according to the feedback of the terminal device, and then the terminal device adjusts the receiving beam according to the transmitting beam adjusted by the network device. The strategy for separately adjusting the transmitting beam and the receiving beam greatly affects the adjustment delay, and particularly, when the terminal device needs to switch the beam rapidly and frequently, the adjustment delay has a greater effect on communication.

Finally, in high frequency scenarios, electromagnetic waves are more easily absorbed by the atmosphere due to the increase in frequency, and therefore more physical antennas must be used for communication services. When the number of antennas increases, the size of the antennas is smaller, and the coverage of the formed beam is narrower, which also brings more frequent beam adjustment and increases the signaling overhead of the system.

In order to solve the above problem, the present application provides a beam management scheme, which on one hand, implements fast adjustment of a transmission beam of a network device and a reception beam of a terminal device through spatial information of multiple beams, and reduces adjustment delay, and on the other hand, implements transmission of downlink data by determining the multiple beams as the transmission beam of the network device, so as to avoid frequent switching of the beams. The scheme of the application will be described with reference to the accompanying drawings.

Fig. 3 is a schematic flowchart of a beam processing method according to an embodiment of the present application, and as shown in fig. 3, the method may include:

s31, spatial information of a plurality of beams is acquired.

Due to the high-frequency radio characteristic, at this time, a direct path of sight (LOS) connection is mostly used, so that the terminal device and the network device can roughly sense the direction of the opposite side in space from the beam direction, and rapid pairing is achieved.

The terminal device and the network device can both acquire the spatial information of the multiple beams, the terminal device can acquire the approximate position of the network device in the space through the spatial information of the multiple beams, and the network device can acquire the approximate position of the terminal device in the space through the spatial information of the multiple beams.

And S32, determining the transmitting beam of the network equipment and/or the receiving beam of the terminal equipment according to the spatial information of the beams.

In the embodiment of the present application, after the spatial information of the multiple beams is determined, the transmit beam of the network device and/or the receive beam of the terminal device may be determined according to the spatial information of the multiple beams, so as to form the optimal connection beam without performing separate adjustment.

According to the beam adjusting method provided by the embodiment of the application, the spatial information of the multiple beams is firstly obtained, and then the transmitting beam of the network device and the receiving beam of the terminal device are determined according to the spatial information of the multiple beams, so that one-step adjustment of the beams is realized, the separate adjustment of the transmitting beam and the receiving beam is not needed, and the adjustment time delay of the beams can be reduced.

Specifically, the terminal device and the network device may form a beam by multiple antennas by using different weights on codebooks or antennas, and point to a direction, so that the weights on the codebooks or antennas form spatial information of multiple beams to indicate an arrangement relationship of the beams in a spatial position or a coverage direction. Fig. 4 is a schematic diagram of spatial information provided in an embodiment of the present application, and as shown in fig. 4, spatial information of multiple beams may be represented in a table-like manner. Each beam is mapped into space according to its codebook.

For example, in fig. 4, a table is provided, in which 9 beams are shown, which can be formed of cb1, cb2, cb3, cb4, cb5, cb6, cb7, cb8 and cb9, respectively. In fig. 4, cb denotes a codebook (code book) which may indicate one directional beam, each cb corresponds to one beam, and the adjacent cbs indicate that the beams corresponding thereto are adjacent in the spatial position or coverage direction.

Through the arrangement relationship indicated by the table, the adjacent beams of any beam can be rapidly acquired, so that the adjacent beams can be used as a reference for the network equipment to select the transmitting beam. For example, in fig. 4, if cb1 is determined as a better beam according to the feedback of the terminal device, the network device may use cb2, cb3, cb4, cb5, cb6, cb7, cb8, and cb9 adjacent to cb1 as the transmission beam of the network device according to the above arrangement relationship. Of course, the network device may use all the beams (cb 2, cb3, cb4, cb5, cb6, cb7, cb8, and cb 9) adjacent to cb1 in the above table as the transmission beams of the network device, or may use some of the beams (for example, cb5, cb4, cb3, and cb 6) as the transmission beams of the network device, which is not particularly limited in this embodiment of the application.

It should be noted that the table illustrated in fig. 4 is only one expression of the spatial information, and does not represent the spatial information, but is the table illustrated in fig. 4. In fig. 4, there is a relationship of adjacent beams, and adjacent beams refers to an adjacent relationship of two beams in a spatial position or coverage direction, corresponding to the beams. For example, two beams may be considered to be spatially adjacent when the distance between the coverage locations of the two beams on the ground is within a certain range, two beams may be considered to be adjacent in the coverage direction when the angle between the coverage directions of the two beams is within a certain angle, and so on.

Optionally, in this embodiment of the present application, the terminal device and the spatial information of multiple beams acquired by the network device are used to indicate an arrangement relationship of each beam in the spatial position or the coverage direction, and according to the arrangement relationship, a beam adjacent to any one beam in the spatial position or the coverage direction can be quickly acquired, so that the network device can determine a transmission beam of the network device according to the arrangement relationship, indicated by the spatial information, of each beam in the spatial position or the coverage direction, and can quickly determine a reception beam by the terminal device. The form of representing the arrangement relationship by the table illustrated in fig. 4 is an example, and it is sufficient if the arrangement relationship of the beams in the spatial position or the coverage direction can be acquired from the spatial information.

The separate adjustment of the beams comprises two processes of transmitting beam selection and receiving beam selection to adjust the beam pairing, and the time delay is large. In the scheme of the application, the pairing of the wave beams can be completed only by one step. Specifically, it is assumed that the terminal device is currently located in the coverage of the beam cb1, and at this time, the terminal device performs fast measurement on possible codebook directions around the current beam, and it is assumed that there are R possible codebook directions around the current beam. The terminal device monitors all the received beams around the received beam space at the same time, and if the number of the received beams is L, the terminal device needs to monitor R × L beam pairs at the same time. Meanwhile, the terminal device may perform conventional monitoring on the beams at the other positions, or may not perform monitoring.

In this way, the codebook around the current beam is actually monitored in a traversal manner, so that beam adjustment can be completed in one step. The terminal device finds the current optimal beam pairing by monitoring the R × L beam pairings, wherein the current optimal beam pairing includes an optimal receiving beam and an optimal transmitting beam, the terminal device only needs to feed back the optimal transmitting beam to the network device, and the terminal device only needs to take the optimal receiving beam as the adjusted receiving beam. The network device may use the best transmit beam fed back by the terminal device as the adjusted transmit beam, or may determine, according to the best transmit beam fed back by the terminal device, a plurality of transmit beams adjacent to the best transmit beam in the spatial position or the coverage direction, and use them together as the transmit beam of the network device. After the transmission beam is determined, the network device may send downlink data to the terminal device through the adjusted transmission beam. When the number of the transmitting beams is multiple, the coverage range is wider than that when the number of the transmitting beams is 1, and as long as the terminal device does not move out of the coverage range of the transmitting beams, beam adjustment can not be performed, so that frequent adjustment of the beams in a high-frequency scene is avoided.

Optionally, if the terminal device finds that there is a beam with a better beam in other directions than the originally monitored beam pair, the terminal device may also initiate a conventional beam adjustment procedure. In the embodiment of the present application, R and L may include all beam directions, and may be determined according to the capability of the terminal device. In a high-frequency scene, if the communication channel can be ensured to be LOS or approximately LOS, beams outside R and/or L around the space can also be selected not to be monitored.

According to the beam processing method provided by the embodiment of the application, the spatial information of a plurality of beams is firstly acquired, and then the transmitting beam of the network device and/or the receiving beam of the terminal device are/is determined according to the spatial information of the plurality of beams. The spatial information of the beams can reflect the arrangement relation of each beam in the spatial position or the coverage direction, so that adjacent beams of any beam in the spatial position or the coverage direction can be determined, and the beams can be rapidly adjusted. The transmitting beam of the network equipment and/or the receiving beam of the terminal equipment are determined through the beam pairing monitored by the terminal equipment and the optimal transmitting beam fed back to the network equipment, so that the number of beams needing to be measured and beam measurement information needing to be fed back during beam measurement are reduced, signaling overhead is reduced during beam switching, and switching delay is reduced. Further, the network device may directly use the best transmission beam fed back by the terminal device as the adjusted transmission beam, or determine a plurality of transmission beams adjacent to each other in the spatial position or the coverage direction as the transmission beam of the network device according to the best transmission beam, so as to achieve larger beam coverage, reduce frequent beam adjustment when the position of the terminal device changes, and reduce system signaling overhead.

Fig. 5 is a schematic flow chart of a beam processing method according to an embodiment of the present application, and as shown in fig. 5, the method includes:

s51, first transmitting beam information is obtained, wherein the first transmitting beam is an initial transmitting beam or a current connecting beam.

In the embodiment of the present application, there are two possible cases of the first transmission beam. In some embodiments, the first transmission beam is an initial transmission beam, and the initial transmission beam at this time is a beam when the network device and the terminal device initially establish a connection. In other embodiments, the first transmit beam may also be a current connection beam, where the current connection beam is a beam for the current network device to communicate with the terminal device.

And S52, determining a transmitting beam set according to the first transmitting beam information.

After determining the first transmit beam information, a transmit beam set may be determined according to the first transmit beam information, where the transmit beam set includes one or more transmit beams, which collectively serve as a transmit beam of the network device.

Fig. 6 is a transmission beam diagram provided in the embodiment of the present application, and as shown in fig. 6, the transmission beam diagram includes a network device 61 and a terminal device 62, the network device 61 determines a transmission beam set according to first transmission beam information, and the transmission beam set includes 3 transmission beams, which are beam 1, beam 2, and beam 3, in total, so that the network device 61 can send downlink data to the terminal device 62 by repeatedly sweeping through the 3 beams. The total coverage area of the 3 beams is larger than that of any one of the 3 beams, so that as long as the terminal device 62 is within the coverage area of any one of the 3 beams, communication with the network device can be achieved without beam switching.

The beam processing method provided by the embodiment of the application includes the steps of firstly obtaining first transmission beam information, wherein the first transmission beam is an initial transmission beam or a current connection beam, and then determining a transmission beam set according to the first transmission beam information, wherein the beams in the transmission beam set are transmission beams of network equipment, and the transmission beam set comprises one or more beams. When the transmission beam set comprises more than one beam, the network device can communicate with the terminal device through the plurality of transmission beams in the transmission beam set, and the beam coverage range of the network device is larger than that of a single beam, so that frequent switching and adjustment of the beams can be effectively reduced, and the system overhead is reduced.

When determining the transmission beam set, first transmission beam information needs to be acquired, and the first transmission beam is an initial transmission beam or a current connection beam.

In an embodiment of the present application, the initial transmission beam, and/or the current connection beam, is determined based on a measurement result of the beam, wherein the measured parameter includes at least one of a reference signal received power and an interference plus noise ratio.

Specifically, when the beam is initially selected, the network device selects a group of beams within a certain range around the strongest beam space as the transmission beam, and the group of beams is the transmission beam set. When the network device sends downlink data to the terminal device, the network device repeatedly sweeps the group of beams or transmits on the plurality of transmitting beams in other multiplexing modes, and the terminal device can receive data according to the optimal receiving beam direction.

At this time, the terminal device needs to report the beam measurement result, i.e. the reference signal received power and/or the interference plus noise ratio. If the event trigger is reported, the reporting condition of the terminal equipment is that the terminal equipment monitors the reference signal received power and the interference-plus-noise ratio in the multi-beam spatial range, and simultaneously monitors the reference signal received power and the interference-plus-noise ratio of the beams in a certain range outside the multi-beam spatial range, wherein the range can be set according to the requirement or the capability of the terminal equipment.

When the terminal device monitors that the quality of the beam outside the multi-beam spatial range is better than the quality of the beam inside the multi-beam spatial range, the terminal device reports the beam, and the reporting mechanism can adjust the reporting mechanism for the original beam. The reporting of the terminal device may be periodic reporting, where the terminal device periodically monitors the reference signal received power and the interference-plus-noise ratio of a certain number of beams within and outside the multi-beam spatial range to determine the transmit beam set of the network device. When the transmission beam set only comprises one transmission beam, the network equipment can send downlink data to the terminal equipment through the transmission beam; when the plurality of transmission beams are included in the transmission beam set, the network device may transmit downlink data to the terminal device through the plurality of transmission beams.

Optionally, the transmission beam set includes a plurality of beams, and the transmission beam set may include the first transmission beam.

Optionally, any transmit beam in the transmit beam set is a transmit beam adjacent to the first transmit beam, and data transmission with the terminal device is implemented through the multiple transmit beams.

In the embodiment of the present application, the transmission beam adjacent to the first transmission beam refers to:

the beam direction and the beam direction of the first transmitting beam form an included angle smaller than or equal to a preset angle in space; or,

the beam covers the transmission beam with a distance smaller than or equal to a preset distance from the beam cover of the first transmission beam in space.

The beam proximity will be explained below with reference to the drawings.

From the beam pointing direction of beam 1 and the beam pointing direction of beam 2, the angle in space between the beam pointing directions of beam 1 and beam 2 can be obtained, as shown in fig. 7, the angle in space between the beam pointing directions of beam 1 and beam 2 is θ.

An angle may be preset as a preset angle, and then θ may be compared with the size of the preset angle. When θ is greater than the preset angle, it can be considered that the beam 1 and the beam 2 are not adjacent beams in the beam pointing direction. Conversely, when θ is less than or equal to the preset angle, it can be considered that the beam 1 and the beam 2 are adjacent beams in the beam pointing direction.

When it is desired to determine a transmit beam adjacent to the first transmit beam in the beam direction, this can be determined in the manner illustrated in fig. 7.

Another approach to determining the proximity beam is described below.

Fig. 8 is a schematic diagram of beam coverage of a beam provided in an embodiment of the present application, as shown in fig. 8, including a beam 1 and a beam 2, and in fig. 8, beam coverage of the beam 1 and the beam 2 is respectively shown, where a coverage position of the beam 1 on the ground is an a position, and a coverage position of the beam 2 on the ground is a B position.

From the beam coverage of beam 1 and the beam coverage of beam 2, the distance of the beam coverage of beam 1 and beam 2 in space can be obtained, as shown in fig. 8, the distance of the beam coverage of beam 1 and beam 2 in space is S.

A distance may be preset as the preset distance and then S may be compared with the preset distance. When S is greater than the preset distance, it can be considered that the beams 1 and 2 are not adjacent beams in the beam coverage. Conversely, when S is less than or equal to the preset distance, it can be considered that the beams 1 and 2 are adjacent beams in the beam coverage.

When it is desired to determine a transmit beam that is adjacent to the first transmit beam in beam coverage, this can be determined in the manner illustrated in fig. 8.

It should be noted that, as long as the case illustrated in fig. 7 or fig. 8 is satisfied, two beams may be considered as adjacent beams, and if both are satisfied, two beams may also be considered as adjacent beams.

Optionally, in some embodiments, the set of transmission beams further includes at least one second transmission beam other than the first transmission beam, and the second transmission beam is determined by the predicted position of the terminal device at the next time.

The second transmitting beam determined by the above method can cover the next position of the terminal device, so that the terminal device is still within the coverage range of the transmitting beam set when reaching the next position, and beam switching is not needed.

Optionally, the predicted position of the terminal device at the next time may be obtained in a variety of ways. For example, the motion trajectory may be obtained by a machine learning method, a kalman filter method, or a terminal device. The machine learning method may be implemented by a machine learning algorithm or a machine learning model known to those skilled in the art, and the machine learning model may be, for example, a deep learning model (deep learning), a reinforcement learning model (reinforcement learning), or the like. The kalman filter mode and the acquisition mode of the motion trajectory reported by the terminal device are also well known to those skilled in the art, and are not described herein again.

When the transmission beam set comprises more than one beam, the network device can communicate with the terminal device through the plurality of transmission beams in the transmission beam set, and the beam coverage range of the network device is larger than that of a single beam, so that frequent switching and adjustment of the beams can be effectively reduced, and the system overhead is reduced. Meanwhile, the second transmitting beam is added into the transmitting beam set by predicting the position of the terminal equipment at the next moment, so that the terminal equipment is still in the coverage range of the transmitting beam set when reaching the position of the next moment, beam switching is not needed, and the system overhead is further reduced.
