[0003] In general, the first node can select a service beam from multiple beams, and the first node can perform wireless link detection, time-frequency offset estimation and other processing based on the service beam. In some scenarios, the first node needs to switch the service beam due to its own movement or the current service beam being blocked. However, there is currently a problem that the service beams determined by the first node and the second node are inconsistent, which will affect the correct demodulation of data transmission and cause a decrease in data transmission rate.

[0027] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] It should be noted that, in this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0029] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0030] In the description of this application, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "multiple" means two or more.

[0031] In an existing mobile communication system, in order to enhance the coverage of the network, the first node and the second node support communication in a multi-beam manner. The multi-beam includes an uplink beam and a downlink beam, that is, the first node and the second node support downlink data transmission based on multiple downlink beams, and also support uplink data transmission based on multiple uplink beams. The management and process of uplink multi-beams are similar to those of downlink multi-beams, and the following description mainly focuses on downlink multi-beams.

[0032] The network architecture of the mobile communication system (including but not limited to 3G, 4G, 5G and future mobile communication systems) in the embodiment of the present application may include a first node and a second node. In some examples, the first node may be a network side device, and the second node may be a user equipment (UE). In other examples, the first node may be a UE, and the second node may be a network side device. In some other examples, in a user side to user side communication scenario, the first node and the second node may both be UEs. The embodiments of the present application are not limited thereto.

[0033] The following description is given by taking the first node as a UE and the second node as a network side device as an example.

[0034] Network-side devices can send synchronization signals, system messages, transmission signaling or business data, etc. through multiple beams.

[0035] In general, the UE can select one of multiple beams as a service beam to communicate with the network side device. For example, wireless link detection and maintenance, time-frequency offset estimation and compensation, etc. can be performed based on the service beam. Each beam corresponds to an access resource, and the network side device can determine the service beam selected by the terminal based on the access resource of the UE. During the process of UE accessing the network, the UE can measure multiple beams, select an optimal beam as the service beam, and use the access resource corresponding to the beam to send a random access request to the network side device. The network side device determines the service beam of the UE based on the access resource selected by the UE, and can subsequently communicate with the UE based on the service beam.

[0036] Due to UE mobility or other factors, the UE's service beam may need to be switched. In related technologies, the switching of the UE's service beam is determined by the network side device. The network side device can send down the measurement resources of multiple beams, generally physical reference signals, and then the UE measures the multiple beams and reports the measurement results to the network side device. Figure 1 As shown, the network side device selects a new service beam for the UE according to the measurement result, and sends an indication message to the UE through L1 signaling, L2 signaling, or L3 signaling to instruct the UE to switch the service beam. The UE switches the service beam according to the received indication message.

[0037] In the related art, the UE does not notify the network side device of the service beam switching result. Therefore, the network side device does not know whether the UE's service beam switching is successful, at what point in time the UE completes the beam switching, and other information. Due to the lack of feedback information, there may be a situation where the UE has not completed the service beam switching, but the network side device mistakenly believes that the UE has completed the service beam switching, and will send information based on the new service beam, but the UE will still receive information based on the old service beam, resulting in inconsistent beams used by both communicating parties. This situation will seriously affect the correct demodulation of data transmission between the UE and the network side device, resulting in a decrease in data transmission rate, and in severe cases may cause wireless link failure.

[0038] Based on this, the present application provides a beam switching method. After the first node (UE) performs beam switching, it will inform the second node (network side device) whether the beam switching is successful, ensuring that the two parties communicate through the same beam after switching if the beam is successfully switched, thereby avoiding the impact of the two parties using different beams for communication on data transmission.

[0039] Figure 2 The present invention provides a schematic diagram of a communication system structure, wherein the communication system includes a network side device and a UE. The network side device may be a base station or a core network element, such as Figure 2 As shown, the embodiment of the present application is described by taking the network side device as a base station as an example.

[0040] In some embodiments, a base station is used to provide wireless access services for UEs. Specifically, a base station provides a service coverage area (also referred to as a cell). UEs entering the area can communicate with the base station via wireless signals to receive wireless access services provided by the base station. In addition, the service coverage area of ​​the base station can also be divided into near field and far field. The UE may be within the range of the near field or the range of the far field.

[0041] In some embodiments, the base station may be an evolution nodeB (eNB), a next generation nodeB (gNB), a transmission receive point (TRP), a transmission point (TP), and some other access node. According to the size of the service coverage area provided, the base station can be divided into a macro base station for providing macro cells, a micro base station for providing pico cells, and a femto base station for providing femto cells. With the continuous evolution of wireless communication technology, future base stations may also adopt other names.

[0042] In some embodiments, the UE may be a device with wireless transceiver functions, such as a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), etc. The embodiments of the present invention do not limit the specific types of UEs.

[0043] It should be understood that Figure 2 is an exemplary structural diagram, Figure 2 The communication system shown includes an unlimited number of devices, for example, an unlimited number of base stations and an unlimited number of UEs. Figure 2 In addition to the equipment shown, Figure 2 The communication system shown may also include other devices, which is not limited thereto.

[0044] It should be understood that the scenarios in which the beam switching method provided in the embodiments of the present application is used include but are not limited to: downlink service beam switching, uplink service beam switching, and sidelink (SL) service beam switching.

[0045] Figure 3 The following is a flow chart of a beam switching method provided in an embodiment of the present application. For example, the beam switching method provided in the present application can be applied to Figure 2 In the communication system shown in FIG. 1 , it can be specifically applied to the first node, that is, Figure 2 In the UE.

[0046] like Figure 3 As shown, the beam switching method provided in the present application may specifically include the following steps:

[0047] S301. A first node receives a beam switching instruction from a second node.

[0048] The beam switching instruction is used to instruct the first node to switch the service beam used for communication to the target beam. The service beam includes but is not limited to: a downlink service beam, an uplink service beam, and an SL service beam.

[0049] In some embodiments, when the first node moves or its service beam is blocked, the second node detects that the service beam currently used by the first node is of poor quality, and may issue a beam switching instruction to instruct the first node to switch its service beam to the target beam.

[0050] As an example, the beam switching instruction carries an identifier of a target beam or information indirectly indicating the target beam to indicate the target beam to be switched. For example, the beam switching instruction carries quasi co-located information (QCL) to indicate the target beam to be switched.

[0051] S302: In response to the beam switching instruction, the first node switches the serving beam.

[0052] In some embodiments, upon receiving the beam switching instruction from the second node, the first node may respond to the beam switching instruction and switch the service beam according to the target beam indicated in the beam switching instruction to switch the service beam to the target beam. The specific process of beam switching can be referred to in the related art and will not be described in detail here.

[0053] S303: The first node sends a beam switching result to the second node.

[0054] The beam switching result is used to indicate whether the service beam of the first node is switched successfully.

[0055] In some embodiments, after performing beam switching, the first node may feed back the beam switching result to the second node according to whether the beam switching is successful, so as to inform the second node of its own beam switching status.

[0056] In some embodiments, the beam switching result may be carried in control information or a media access control (MAC) control element (CE) for transmission, wherein the control information includes but is not limited to uplink control information (UCI) and downlink control information (DCI).

[0057] As an example, in the case where the beam switching is successful, the first node can feed back a beam switching result including switching success information to the second node, and the beam switching result including the switching success information can be used to indicate that the service beam switching is successful. Similarly, in the case where the beam switching fails, the first node can feed back a beam switching result that does not include switching success information to the second node, so as to indicate to the second node that the service beam switching of the first node has failed.

[0058] As another example, when the beam switching is successful, the first node may feed back the beam switching result including the switching result indication field to the second node. When the value corresponding to the switching result indication field is the first value (for example, the value 1), the beam switching result is used to characterize the success of the service beam switching. Similarly, when the value corresponding to the switching result indication field is the second value (for example, the value 0), the beam switching result is used to characterize the failure of the beam switching. The second node may detect the value of the switching result indication field in the beam switching result to determine whether the service beam switching of the first node is successful.

[0059] In some embodiments, after the above S303, the beam switching method provided in the embodiment of the present application further includes the following S304: S304: If the switching is successful, the first node communicates with the second node through the target beam.

[0060] It should be understood that in the related art, if the first node fails to switch, the first node will still communicate based on the original service beam, and the second node will communicate based on the switched target beam, which will cause the beams used by both parties to be inconsistent, affecting the demodulation of the signal. Therefore, in the present application, the first node will feedback the beam switching situation to the second node to ensure that both parties communicate based on the same beam, which can avoid the above problems.

[0061] Figure 4 A schematic diagram of another beam switching method provided in an embodiment of the present application. For example, the beam switching method provided in the present application can be applied to Figure 2 In the communication system shown in FIG. 1 , it can be specifically applied to the second node, that is, Figure 2 In the base station.

[0062] like Figure 4 As shown, the beam switching method provided in the present application may specifically include the following steps:

[0063] S401. The second node sends a beam switching instruction to the first node.

[0064] The beam switching instruction is used to instruct the first node to switch the service beam used for communication to the target beam.

[0065] In some embodiments, when the service beam of the first node needs to perform beam switching, the second node can determine the target beam to be switched, and then issue a beam switching instruction to instruct the first node to switch the service beam used for communication to the target beam.

[0066] As an example, the first node may periodically, semi-continuously, or non-periodically (for example, based on a preset rule) measure multiple beams between the first node and the second node to obtain measurement results. The measurement results include multiple beams and the reference signal receiving power (RSRP) corresponding to each beam. Furthermore, the first node may report the measurement results periodically, semi-continuously, or non-periodically. The second node may receive the measurement results and determine whether the signal quality of the service beam of the first node is qualified and whether the service beam needs to be switched based on the measurement results. If it is determined that the RSRP of the service beam is less than a certain value, it is determined to be inappropriate and the service beam needs to be switched.

[0067] In the case of determining that switching is required, the second node may determine the target beam to be switched according to the measurement results reported by the first node and the RSRP of multiple beams. For example, the second node may determine a beam with an RSRP greater than a preset threshold as the target beam, or determine a beam with the largest RSRP as the target beam. Alternatively, the second node may select a target beam from multiple beams according to a preset rule without referring to the measurement results, and the embodiment of the present application does not limit this specific implementation.

[0068] S402: The second node determines whether the service beam of the first node is switched successfully.

[0069] In some embodiments, after sending a beam switching instruction, the second node can determine whether the service beam of the first node is switched successfully based on whether feedback from the first node is received after sending the beam switching instruction, or the feedback information of the first node. For a specific description, see the following embodiments.

[0070] In some embodiments, in the above S402, determining that the service beam switching of the first node is successful includes: when the beam switching result of the first node is received within a preset time length after sending the beam switching instruction, and the beam switching result indicates that the service beam switching is successful, determining that the service beam switching of the first node is successful.

[0071] Exemplarily, the second node may initialize and set a timer, and start timing after sending the beam switching instruction, and the timing duration is a preset duration. If the second node receives the beam switching result fed back by the first node before the timer times out, and the beam switching result includes information that the beam switching is successful, then the second node may determine that the service beam switching of the first node is successful.

[0072] In some embodiments, in the above S402, determining that the service beam switching of the first node has failed includes: within a preset time length after sending the beam switching instruction, receiving the beam switching result of the first node, and when the beam switching result indicates that the service beam switching has failed, determining that the service beam switching of the first node has failed.

[0073] Alternatively, within a preset time period after sending the beam switching instruction, no feedback information from the first node is received, and it is determined that the service beam switching of the first node has failed.

[0074] Exemplarily, the second node may initialize and set a timer, and start timing after sending a beam switching instruction, and the timing duration is a preset duration. If before the timer times out, the second node receives the beam switching result fed back by the first node, and the beam switching result does not contain information about successful beam switching or contains information about failed beam switching, then the second node may determine that the service beam switching of the first node has failed. If after the timer times out, the second node still has not received feedback from the first node, then the second node may determine that the service beam switching of the first node has failed.

[0075] S403: When the switching is successful, the second node communicates with the first node via the target beam.

[0076] In some embodiments, when it is determined that the service beam of the first node is switched successfully, the second node can communicate with the first node based on the switched service beam, i.e., the target beam, to ensure that the first node and the second node can communicate using a consistent beam.

[0077] In some embodiments, after the above S402, the method further includes the following S404. It should be understood that S404 is in parallel with the above S403.

[0078] S404: In case of switching failure, the second node retransmits the beam switching instruction.

[0079] It can be understood that when the second node determines that the beam switching of the first node has failed, it is possible that the first node has not received the beam switching instruction of the second node, or the process of executing the beam switching has timed out. Therefore, after determining that the beam switching has failed, the second node can re-issue the beam switching instruction to instruct the first node to retry the beam switching. For the retransmitted beam switching instruction, the first node can continue to execute the above S301-S303, and the second node can continue to execute the above S401-S403.

[0080] In some embodiments, when the first node fails to switch to the target beam multiple times, for example, the number of switching failures is greater than 3 times, the second node can re-determine a new target beam from multiple beam nodes and send a beam switching instruction to instruct the first node to switch to the new beam for communication.

[0081] It can be understood that in the event of a beam switching failure, the second node can retransmit the beam switching instruction to instruct the first node to retry the beam switching, which can effectively avoid the impact of the wireless link due to the blocking of the business process.

[0082] In the beam switching method provided in the embodiment of the present application, after the first node receives the beam switching instruction to perform beam switching, it sends the beam switching result to the second node. The second node can determine whether the service beam of the first node has been successfully switched based on the beam switching result, and communicate with the first node through the switched beam if the switching is successful. This method can ensure that the two parties communicate through the same switched beam when the beam is successfully switched, avoid the two parties using different beams to communicate, which affects the correct demodulation of data transmission, and can effectively improve the data transmission rate.

[0083] Figure 5 A schematic diagram of a beam switching process provided in an embodiment of the present application. Figure 5 As shown, the network side device sends a beam switching instruction to the UE. In response to the instruction, the UE performs a switching of the service beam to switch to the target beam. After performing the switching, the UE reports the beam switching result to the network side device. If the service beam switching is successful, the UE and the network side device communicate through the target beam.

[0084] It is understandable that the beam switching device (which may be the first node or the second node mentioned above) includes hardware structures and / or software modules corresponding to the execution of each function in order to implement the above functions. Those skilled in the art should easily realize that, in combination with the algorithm steps of each example described in the embodiments of the present application, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of this application.

[0085] The embodiment of the present application can divide the beam switching device into functional modules according to the above method embodiment. For example, each functional module can be divided corresponding to each function, or two or more functions can be integrated into one functional module. The above integrated module can be implemented in the form of hardware or software. It should be noted that the division of modules in the embodiment of the present application is schematic and is only a logical function division. There may be other division methods in actual implementation. The following is an example of dividing each functional module corresponding to each function.

[0086] Figure 6 is a schematic diagram of the structure of a beam switching device provided in an embodiment of the present application. The beam switching device can execute the beam switching method provided in the above method embodiment. Figure 6 As shown, the beam switching device includes: a receiving module 601, a switching module 602 and a sending module 603.

[0087] The receiving module 601 is used to receive a beam switching instruction from the second node; the beam switching instruction is used to instruct the first node to switch the service beam used for communication to a target beam.

[0088] The switching module 602 is used to switch the service beam in response to the beam switching instruction; the sending module 603 is used to send the beam switching result to the second node.

[0089] The beam switching result is used to indicate whether the service beam of the first node is switched successfully.

[0090] In some embodiments, the above apparatus further includes a communication module 604. The communication module 604 is configured to communicate with the second node through the target beam when the handover is successful.

[0091] In some embodiments, the beam switching result is carried in the control information or MAC CE.

[0092] Figure 7is a schematic diagram of the structure of another beam switching device provided in an embodiment of the present application. The beam switching device can execute the beam switching method provided in the above method embodiment. Figure 7 As shown, the beam switching device includes: a sending module 701, a determining module 702 and a communication module 703.

[0093] The sending module 701 is used to send a beam switching instruction to the first node; the beam switching instruction is used to instruct the first node to switch the service beam used for communication to a target beam.

[0094] The determination module 702 is used to determine whether the service beam of the first node is switched successfully.

[0095] The communication module 703 is used to communicate with the first node through the target beam when the switching is successful.

[0096] In some embodiments, the determination module 702 is specifically used to determine that the service beam switching of the first node is successful when a beam switching result of the first node is received within a preset time period after sending the beam switching instruction, and the beam switching result indicates that the service beam switching is successful.

[0097] In some embodiments, the determination module 702 is specifically used to determine that the service beam switching of the first node has failed if a beam switching result of the first node is received within a preset time after sending the beam switching instruction, and the beam switching result indicates that the service beam switching has failed; or, if no feedback information from the first node is received within a preset time after sending the beam switching instruction, determine that the service beam switching of the first node has failed.

[0098] In some embodiments, the sending module 701 is further configured to retransmit the beam switching instruction in case of a switching failure.

[0099] In some embodiments, the beam switching result is carried in the control information or MAC CE.

[0100] In the case of implementing the functions of the above-mentioned integrated modules in the form of hardware, the embodiment of the present application provides another possible structure of the communication device involved in the above-mentioned embodiment. Figure 8 As shown, the communication device 80 includes: a processor 802 and a bus 804. Optionally, the communication device may further include a memory 801; optionally, the communication device may further include a communication interface 803.

[0101] The processor 802 may be a processor that implements or executes various exemplary logic blocks, modules, and circuits described in conjunction with the embodiments of the present application.

[0104] As a possible implementation, the memory 801 may exist independently of the processor 802, and the memory 801 may be connected to the processor 802 via a bus 804 for storing instructions or program codes. When the processor 802 calls and executes the instructions or program codes stored in the memory 801, the beam switching method provided in the embodiment of the present application can be implemented.

[0105] In another possible implementation, the memory 801 may also be integrated with the processor 802 .
