Description

Technical Field

[0001] This application relates to communication technologies, and in particular, to a method, device, and storage medium for determining a transmission beam. Background Art

[0002] In 5G New Radio (NR), due to the application of large-scale antenna arrays based on beams, the system can form one or at least one highly directional beam. Especially in high-frequency scenarios, this method can improve the system coverage area while reducing interference.

[0003] In a multi-transmit receive point (TRP) scenario, a base station is equipped with at least one TRP. Each TRP can be centrally placed or separately placed. Each TRP needs to adjust the beam according to the movement of the terminal so that the direction of the transmission beam is always aligned with the moving terminal. The terminal device needs to continuously monitor the quality of at least one beam and report the measurement results. The base station determines the transmission beams after adjustment of different TRPs based on the reported results. In a high-frequency system, since the coverage range of each beam is relatively narrow, when the terminal device moves rapidly, frequent beam adjustments may be involved, resulting in frequent signaling interactions between the terminal device and the base station, and thus a serious decline in system performance.

[0004] Therefore, there is an urgent need for a solution to solve the problem that the system in a high-frequency multi-TRP scenario needs to frequently adjust the beam.

[0115] For ease of understanding, the concepts involved in the present application are first explained.

[0116] Terminal device: It can be a device that includes wireless transceiver functions and can cooperate with a network device to provide communication services for users. Specifically, the terminal device can refer to a user equipment (UE), access terminal, user unit, user station, mobile station, mobile terminal, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. For example, the terminal device can be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device with wireless communication function, computing device or other processing devices connected to a wireless modem, vehicle-mounted device, wearable device, terminal device in a future 5G network or a network after 5G, etc.

[0117] Network device: A network device can be a device used to communicate with a terminal device. For example, it can be a Base Transceiver Station (BTS) in a Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA) communication system, or a NodeB (NB) in a Wideband Code Division Multiple Access (WCDMA) system, or an Evolutional Node B (eNB or eNodeB) in an LTE system. Or the network device can be a relay station, an access point, a vehicle-mounted device, a wearable device, and a network-side device in a future 5G network or a network after 5G, or a network device in a future evolved Public Land Mobile Network (PLMN).

[0118] The network device involved in the embodiments of this application can also be referred to as a Radio Access Network (RAN) device. The RAN device is connected to the terminal device and is used to receive the data of the terminal device and send it to the core network device. The RAN device corresponds to different devices in different communication systems. For example, in a 2G system, it corresponds to a base station and a base station controller; in a 3G system, it corresponds to a base station and a Radio Network Controller (RNC); in a 4G system, it corresponds to an Evolutional Node B (eNB); in a 5G system, it corresponds to the access network devices in the 5G system, such as gNB, a Central Unit (CU), and a Distributed Unit (DU) in NR.

[0119] Beam: It refers to the characteristic that the energy of the electromagnetic wave emitted by the antenna is concentrated in a certain area in space.

[0120] Next, in combination with Figure 1 , the scenarios applicable to the method in this application will be described.

[0121] Figure 1 It is a schematic diagram of the application scenario provided by the embodiments of this application. Please refer to Figure 1 , which includes a first Transmission and Reception Point (TRP) 101, a second TRP 102, and a terminal device 103. Wireless communication can be performed between the first TRP 101, the second TRP 102, and the terminal device 103.

[0122] Among them, the first TRP101 can transmit multiple beams to cover a certain range. The terminal devices within this range can communicate and interact with the first TRP101. Similarly, the second TRP102 can transmit multiple beams to cover a certain range. The terminal devices within this range can communicate and interact with the second TRP102.

[0123] In Figure 1 the example of, the coverage ranges of the multiple beams transmitted by the first TRP101 and the multiple beams transmitted by the second TRP102 have a certain overlap, as Figure 1 schematically shown in the multi-beam service area 10. Within the multi-beam service area 10, it belongs to both the coverage range of the first TRP101 and the coverage range of the second TRP102. In the embodiments of the present application, the terminal device 103 is within the multi-beam service area 10.

[0124] It should be noted that a network device may include multiple TPRs. In the embodiments of the present application, a network device includes at least two TRPs. Figure 1 The example application scenario is merely described by taking two TRPs as an example, and does not constitute a limitation on the number of TRPs.

[0125] It can be understood that the technical solution of the embodiments of the present application can be applied to NR communication technology. NR refers to the new generation wireless access network technology and can be applied to future evolved networks, such as the future 5th Generation Mobile Communication (5G) system. The solution in the embodiments of the present 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 with the names of the corresponding functions in other wireless communication networks.

[0126] The network architecture and service scenarios described in the embodiments of the present application are for more clearly explaining the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided by the embodiments of the present application. Those of ordinary skill in the art know that with the evolution of the network architecture and the emergence of new service scenarios, the technical solution provided by the embodiments of the present application is equally applicable to similar technical problems.

[0127] Figure 2 It is a schematic flowchart of the method for determining the transmission beam provided by the embodiments of the present application. This method is applied to a network device, and the network device includes a first TRP and at least one second TRP, as Figure 2 shown, this method may include:

[0128] S21. Determine the first beam to which the first TRP is currently connected to the terminal device. The terminal device is connected to the network device through the first TRP and the second TRP.

[0129] The network device includes a first TRP and at least one second TRP. The first TRP can transmit a beam to cover a certain range, and each second TRP can also transmit a beam to cover a certain range. The terminal device is connected to the network device through the first TRP and the second TRP. When the terminal device is connected to the network device through the first TRP, the terminal device is within the coverage range of the first TRP. When the terminal device is connected to the network device through the second TRP, the terminal device is within the coverage range of the second TRP. Therefore, the terminal device is within the overlapping coverage range of the first TRP and the second TRP. Among them, the terminal device is connected to the first TRP through the first beam, and the first beam is the beam to which the first TRP is currently connected to the terminal device.

[0130] S22. Determine the first transmission beam of the first TRP and the second transmission beam of the second TRP according to the first beam.

[0131] After determining the first beam to which the first TRP is currently connected to the terminal device, the first transmission beam of the first TRP and the second transmission beam of the second TRP can be determined according to the first beam. Among them, the first transmission beam includes the first beam and may also include other transmission beams.

[0132] Since the terminal device is within the overlapping coverage range of the first TRP and the second TRP, the second transmission beam of the second TRP is determined according to the first beam. After the terminal device moves, there is still a high possibility that it is within the coverage range of the first transmission beam of the first TRP or the second transmission beam of the second TRP. The terminal device can establish a connection and communicate with the network device through the first transmission beam or the second transmission beam, avoiding the need for beam switching as soon as the terminal device moves.

[0133] The method for determining a transmission beam provided by an embodiment of this application is applied to a network device. The network device includes a first TRP and at least one second TRP. A terminal device is connected to the network device through the first TRP and the second TRP. The network device first determines a first beam to which the first TRP is currently connected to the terminal device, and then can determine a first transmission beam of the first TRP and a second transmission beam of the second TRP according to the first beam. In a high-frequency multi-TRP scenario, when the terminal device is located within the overlapping coverage range of the first TRP and the second TRP, by determining the first transmission beam of the first TRP and the second transmission beam of the second TRP, the coverage range for the terminal device is improved. When the position of the terminal device changes, frequent beam adjustments are avoided, signaling waste in the system is reduced, and the communication efficiency of the system is improved.

[0134] The solution of this application will be introduced in detail below with specific embodiments.

[0135] After determining the first beam, at least one first spatial information of the transmission beams of the first TRP and at least one second spatial information of the transmission beams of the second TRP can be obtained. Among them, at least one of the transmission beams of the first TRP includes the first beam. Among them, the determination of the first beam can be achieved by the terminal device reporting the beam measurement result of the first TRP. After the first TRP receives the beam measurement result of the first TRP from the terminal device, it can determine the first beam to which it is currently connected according to the beam measurement result of the first TRP.

[0136] Optionally, the first spatial information is used to indicate a first arrangement relationship of at least one transmission beam of the first TRP in terms of spatial position or coverage direction; the second spatial information is used to indicate a second arrangement relationship of at least one transmission beam of the second TRP in terms of spatial position or coverage direction.

[0137] After obtaining the first spatial information and the second spatial information, according to the first spatial information, the second spatial information, and the first beam, a second beam is determined among at least one beam of the second TRP, and according to the first beam and the second beam, the first transmission beam and the second transmission beam are determined.

[0138] Optionally, the combined coverage range of the first transmission beam and the second transmission beam is greater than the coverage range of the first beam, so that when the terminal device moves within the combined coverage range of the first transmission beam and the second transmission beam, beam adjustment is not required.

[0139] Figure 3 For the schematic diagram of determining the second beam provided by the embodiment of this application, as Figure 3As shown, it includes a first TRP and a second TRP. The first TRP can transmit one or more first transmission beams, and the second TRP can transmit one or more second transmission beams. The terminal device is located within the overlapping coverage area of the first TRP and the second TRP.

[0140] In Figure 3 , the terminal device is connected to the first TRP through beam 31, and beam 31 is the first beam. After obtaining the first spatial information, the spatial relationship between one or more first transmission beams of the first TRP and beam 31 can be known. After obtaining the second spatial information, the spatial relationship between one or more second transmission beams of the second TRP and one or more first transmission beams of the first TRP can be known.

[0141] Therefore, the second beam can be determined based on the first spatial information, the second spatial information, and beam 31.

[0142] For example, at least one pair of beam correspondence relationships of at least one TRP can be obtained according to the first spatial information and the second spatial information, where each pair of beam correspondence relationships indicates one beam of the first TRP and one beam of the second TRP; the second beam is determined according to the beam correspondence relationship and the first beam.

[0143] In the above beam correspondence relationship, the coverage ranges of the two beams indicated by each pair of beam correspondence relationships are the same.

[0144] The acquisition of the beam correspondence relationship will be introduced below in conjunction with the accompanying drawings.

[0145] Figure 4 It is a schematic diagram of the beam spatial information correspondence table provided by the embodiment of the present application. As Figure 4 shown, it shows the beams that a TRP can transmit, and the spatial relative position relationships of each beam. Among them, Figure 4 the horizontal direction is the horizontal direction, and the vertical direction is the vertical direction.

[0146] In Figure 4 , each CB represents a beam, different beams are numbered differently, and the position of each beam in the figure reflects the spatial information of the beam. For example, in Figure 4 , CB10 and CB11 are adjacent, indicating that the coverage range of beam CB10 is relatively close to the coverage range of beam CB11. CB11 is between CB10 and CB12, indicating that the coverage range of beam CB11 is between the coverage range of beam CB10 and the coverage range of beam CB12, and so on. The positions of each CB in Figure 4 basically correspond to the positions where the coverage ranges of the corresponding beams are located.

[0147] The first spatial information for the first TRP is used to indicate the first arrangement relationship of at least one transmission beam of the first TRP in terms of spatial position or coverage direction. For any beam i among at least one transmission beam of the first TRP, the first arrangement relationship is used to determine the beam adjacent to beam i of the first TRP in terms of spatial position or coverage direction.

[0148] Similarly, the second spatial information for the second TRP is used to indicate the second arrangement relationship of at least one transmission beam of the second TRP in terms of spatial position or coverage direction. For any beam j among at least one transmission beam of the second TRP, the second arrangement relationship is used to determine the beam adjacent to beam j of the second TRP in terms of spatial position or coverage direction.

[0149] Among them, the first spatial information and the second spatial information are schematically illustrated as in Figure 4 the schematic diagram of the beam space information correspondence table. The number and arrangement of beams under different TRPs may be different, but the acquisition of their beam space information is similar and will not be elaborated here.

[0150] Figure 5 The schematic diagram of the beam correspondence relationship provided by the embodiment of the present application is as in Figure 5 shown. Taking two TRPs as an example, including the first TRP and the second TRP, each TRP includes a beam space information correspondence table.

[0151] In Figure 5 , both the first TRP and the second TRP include multiple transmission beams. The shaded part represents the overlapping area of the coverage ranges of the first TRP and the second TRP. Among them, CB10 under the first TRP corresponds to CB10 under the second TRP, CB11 under the first TRP corresponds to CB11 under the second TRP, CB12 under the first TRP corresponds to CB12 under the second TRP, CB13 under the first TRP corresponds to CB13 under the second TRP, and so on. The correspondence relationship is as in Figure 5 the curve arrows shown. Figure 5 A pair of beams indicated by the curve arrows in Figure 5 corresponds to a pair of beam correspondence relationships, such as CB10 under the first TRP corresponding to CB10 under the second TRP. It should be noted that

[0152] Only some beam correspondence relationships are schematically shown by the curve arrows in , rather than all the beam correspondence relationships.

[0152] If the first beam is the beam to which the terminal device is currently connected to the first TRP, then the terminal device is located within the coverage range of the first beam. Since the terminal device is located within the overlapping coverage range of the first TRP and the second TRP, the terminal device is also located within the coverage range of a certain beam of the second TRP.

[0153] Optionally, the coverage ranges of the first beam and the second beam are the same. In Figure 3 , the first beam is beam 31 and the second beam is beam 32. The beam that the terminal device is currently connected to the first TRP is beam 31, indicating that the terminal device is currently within the coverage range of beam 31. Since the coverage ranges of beam 31 and beam 32 are the same, it means that the terminal device is also within the coverage range of beam 32.

[0154] After determining the first beam and the second beam, the first transmission beam and the second transmission beam can be determined based on the first beam and the second beam, where the number of the first transmission beams is one or more, and the number of the second transmission beams is one or more.

[0155] Specifically, the first transmission beam can be determined according to the first beam, and the second transmission beam can be determined according to the second beam. The determination of the first transmission beam and the second transmission beam will be introduced separately below with reference to the accompanying drawings.

[0156] Figure 6 FIG. is a schematic diagram of the determination of the second transmission beam provided by an embodiment of the present application. As Figure 6 shown, the second TRP can transmit multiple transmission beams. In Figure 6 , 8 transmission beams are exemplified, which are beam 61, beam 62, beam 63, beam 64, beam 65, beam 66, beam 67, and beam 68 respectively.

[0157] Among them, the second beam is beam 65. After determining the second beam, the second transmission beam is determined according to the second beam, and the number of the second transmission beams is one or more. When the number of the second transmission beams is one, the second transmission beam can be the second beam (i.e., Figure 6 beam 65 in Figure 6 ), or it can be other beams with a coverage range closer to that of the second beam (such as

[0158] beam 64, beam 66, etc. in Figure 6 ).

[0159] There are multiple implementation manners on how to specifically determine the second transmission beam according to the second beam, which will be introduced separately below.

[0160] Figure 7 FIG. is a schematic diagram of the determination of the second transmission beam provided by an embodiment of the present application. As Figure 7As shown, it is a schematic diagram of the beam space information of the second TRP, which includes multiple transmission beams. The second beam is CB27.

[0161] After determining that the second beam is CB27, the second transmission beam can be further determined.

[0162] A possible implementation is to determine the second transmission beam according to the second beam and the second space information, where the second space information is obtained through Figure 7 the schematic diagram of the beam space information of the exemplary second TRP.

[0163] In Figure 7 the schematic diagram of the beam space information of the second TRP indicates the relative spatial relationship of each beam. Through the schematic diagram of the beam space information of the second TRP, the relationship of each beam relative to the second beam CB27 can be obtained.

[0164] Optionally, the second transmission beam is one or more beams adjacent to the second beam, where the beams adjacent to the second beam are indicated by the schematic diagram of the beam space information of the second TRP. For example, in Figure 7 when it is determined that the second beam is CB27, CB26 and CB28 can be used as the second transmission beam to increase the multi-beam coverage in the horizontal direction; CB19 and CB35 can also be used as the second transmission beam to increase the multi-beam coverage in the vertical direction; CB18, CB20, CB34, CB36 can also be used as the second transmission beam, and so on.

[0165] Another possible implementation is that the base station realizes it by configuring the beam adjustment parameter Bshift. Specifically, obtain the beam adjustment parameter, and determine the second transmission beam according to the beam adjustment parameter and the second beam.

[0166] In the embodiments of the present application, the beam adjustment parameter may include a beam direction adjustment parameter and / or a beam offset value.

[0167] Optionally, the network device can determine the second transmission beam according to the beam direction adjustment parameter and the second beam. For example, in Figure 7 when the second beam is CB27, if the beam direction adjustment parameter is upward, according to Figure 7 the indication of the schematic diagram of the beam space information of the second TRP, CB19 above CB27, or CB19 and CB11, can be selected as the second transmission beam; if the beam direction adjustment parameter is to the right, according to Figure 7 the indication of the schematic diagram of the beam space information of the second TRP, CB28 to the right of CB27, or CB28 and CB29, can be selected as the second transmission beam, and so on.

[0168] Optionally, the network device may determine a second transmission beam according to a beam offset value, a second beam, and second spatial information. For example, in Figure 7 , the second beam is CB27. If the beam offset value is 1, according to the schematic diagram of the beam spatial information of the second TRP in Figure 7 , one or more of CB19, CB26, CB35, and CB28 adjacent to CB27 can be selected as the second transmission beam; if the beam offset value is 2, one or more of CB11, CB43, and CB29 can be selected as the second transmission beam, and so on.

[0169] Optionally, the network device may determine a second transmission beam according to a beam direction adjustment parameter, a beam offset value, a second beam, and second spatial information. For example, in Figure 7 , the second beam is CB27. If the beam direction adjustment parameter is upward and the beam offset value is 1, according to the schematic diagram of the beam spatial information of the second TRP in Figure 7 , CB19 above CB27 can be selected as the second transmission beam; if the beam direction adjustment parameter is rightward and the beam offset value is 2, CB29 can be selected as the second transmission beam, and so on.

[0170] In the embodiments of the present application, the beam adjustment parameter may also be a beam index. When the beam adjustment parameter is a beam index, the beam index indicates at least one transmission beam of the second TRP. At this time, the base station may configure a beam index for each transmission beam of the second TRP. When the beam adjustment parameter is a beam index, according to the corresponding beam index in the beam adjustment parameter, the beam index of the second transmission beam can be determined, and then the second transmission beam can be determined.

[0171] Optionally, the beam adjustment parameter may be determined by obtaining the position of the terminal device at the next moment and according to the position of the terminal device at the next moment.

[0172] Optionally, the position of the terminal device at the next moment may be obtained by a machine learning method, or may be obtained by a Kalman filter method, or may be obtained by motion parameters reported by the terminal device, and so on.

[0173] In the above embodiments, a solution for determining a second transmission beam according to a second beam is described. The solution for determining a first transmission beam according to a first beam is similar to the solution for determining a second transmission beam according to a second beam, and will not be elaborated here.

[0174] The method for determining a transmission beam provided by an embodiment of this application is applied to a network device. The network device includes a first TRP and at least one second TRP. The terminal device is connected to the network device through the first TRP and the second TRP. The network device first determines the first beam currently connected between the first TRP and the terminal device, and then can determine the first transmission beam of the first TRP and the second transmission beam of the second TRP according to the first beam. In a high-frequency multi-TRP scenario, when the terminal device is located within the overlapping coverage range of the first TRP and the second TRP, by determining the first transmission beam of the first TRP and the second transmission beam of the second TRP, the coverage range for the terminal device is improved. When the position of the terminal device changes, frequent beam adjustments are avoided, signaling waste in the system is reduced, and the communication efficiency of the system is improved.
