Abstract
Description

[0002] Currently, based on the research on the shared network architecture of 5G / 5G+ (5th Generation Mobile Communication Technology) and 6G (6th generation mobile networks), it has been found that when a 5G / 5G+ (6G) multi-mode terminal enters the connected state from the idle state, the 5G / 5G+ or 6G base station traverses or scans all access beam directions to detect and search for the optimal access beam direction.
[0003] This method of determining the optimal access beam direction increases the time required for 5G / 5G+ (6G) multi-mode terminals to access 5G / 5G+ or 6G base stations, which increases access latency and affects the rapid access of users and the rapid increase of peak data rates, thereby degrading the user experience.

[0069] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities.
[0070] Currently, based on research on the shared network architecture of 5G / 5G+ and 6G access networks, it has been found that when a 5G / 5G+ (6G) multi-mode terminal enters the connected state from the idle state, the 5G / 5G+ or 6G base station traverses or scans all access beam directions to detect and search for the optimal access beam direction.
[0071] This method of determining the optimal access beam direction increases the time required for 5G / 5G+ (6G) multi-mode terminals to access 5G / 5G+ or 6G base stations, which increases access latency and affects the rapid access of users and the rapid increase of peak data rates, thereby degrading the user experience.
[0072] To address the problems existing in related technologies, this disclosure proposes a beam determination method applicable to multimode terminals. Figure 1 A flowchart of the beam determination method is shown, such as Figure 1 As shown, the beam determination method includes at least the following steps:
[0073] Step S110. Obtain the first signal beam of the first base station and the second signal beam of the second base station, and establish a mapping relationship between the first signal beam and the second signal beam.
[0074] Step S120. If the multi-mode terminal meets the preset conditions, determine the target access beam in the second signal beam corresponding to the current access beam in the first signal beam according to the mapping relationship.
[0075] Step S130. Access the second base station through the target access beam so that the second base station responds.
[0076] In an exemplary embodiment of this disclosure, a mapping relationship is established between the first signal beam of the first base station and the second signal beam of the second base station, providing a data basis and theoretical support for determining the target access beam.
[0077] Furthermore, by determining the target access beam based on the mapping relationship and the current access beam, it is not necessary to perform beam scanning and detection in a wide range of second signal beams. This reduces the detection range for determining the target access beam, shortens the detection time of the target access beam of the second base station, and also improves the speed and efficiency of the access beam detection of the second base station.
[0078] Furthermore, by accessing the second base station through the target access beam, time is saved in three aspects: beam scanning, beam detection, and beam decision-making, thus achieving the goal of quickly accessing the second base station and quickly receiving the response from the second base station.
[0079] Furthermore, it has further optimized peak speed and user experience, improved the network performance of multi-mode terminals, and is conducive to the continued evolution towards 5G+ and 6G technologies, with very broad application prospects.
[0080] The following section provides a detailed explanation of each step in the beam determination method.
[0081] In step S110, the first signal beam of the first base station and the second signal beam of the second base station are obtained, and a mapping relationship between the first signal beam and the second signal beam is established.
[0082] In exemplary embodiments of this disclosure, with the development of mobile communication technology, more and more new types of networks have emerged, such as Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) networks and Long Term Evolution (LTE) networks. New networks face insufficient coverage in the early stages of deployment, and in the later stages, they face the challenge of interoperability with existing networks, such as the Global System for Mobile Communications (GSM) network.
[0083] Currently, multi-mode terminals are primarily used to enable operation between different network systems. Typically, a newer network is designated as the preferred network for the multi-mode terminal; that is, after powering on, the terminal preferentially resides on the newer network. If it is detected that the newer network cannot be used due to signal quality degradation or other reasons, an inter-system switch is initiated to revert to the existing network. Furthermore, with continuous optimization of parameters and mechanisms, the success rate of inter-system handover has been significantly improved.
[0084] Correspondingly, the multi-mode terminal can access a dual-mode base station or a multi-mode base station. For example, a dual-mode base station can be a 5G / 5G+ base station or a 5G / 6G base station, and a multi-mode base station can be a 5G / 5G+ / 6G base station. In addition, with the development and updating of communication technology, dual-mode base stations or multi-mode base stations can also be other types of base stations, and this exemplary embodiment does not impose any special limitations on them.
[0085] Among them, 5G+ stands for 5G Advanced.
[0086] With the release of the first 5G NR standard version (Rel-15) in 2019, the global industrialization of 5G has begun on a large scale. Statistics show that by 2020, 5G base stations had been deployed in all prefecture-level cities and some county-level cities in China, and 5G mobile phone shipments in China alone exceeded 150 million units in 2020. As the basic version of NR, Rel-15 primarily targets traditional eMBB services. In the subsequent Rel-16 and Rel-17 evolution versions, 3GPP (3rd Generation Partnership Project) further explored more vertical industry applications and support, and improved the 5G network in multiple ways from the following dimensions.
[0087] 3GPP is a collaborative project within the mobile communications industry, primarily aimed at organizing the development and management of mobile communication standards. In the 5G field, 3GPP is responsible for managing the continuously evolving 5G standards.
[0088] The first is greater spectrum and bandwidth utilization, such as the 52.6–71 GHz millimeter wave band; the second is support for industrial internet applications, which can be considered an enhancement of URLLC scenarios to meet the low latency and high reliability requirements of industrial applications; the third is support for more types of terminal devices, such as wearable devices, video surveillance, wireless sensors, virtual / augmented reality (XR), etc.; the fourth is more diverse network forms, such as vehicle-to-everything (V2X), non-terrestrial networks (NTN), and integrated access and backhaul (IAB), etc.
[0089] Wireless communication networks are typically updated every ten years. With the large-scale deployment of 5G base stations and the widespread adoption of user terminals, people are increasingly anticipating the new applications and experiences that next-generation communication technologies will bring. Recently, the IMT-2030 organization released a white paper on the overall vision and potential key technologies for 6G, which identified some popular research directions, such as artificial intelligence, immersive cloud XR, integrated air-space-ground communication, integrated communication and sensing, holographic communication, digital twins, terahertz and visible light communication, etc.
[0090] From the perspective of standards evolution and industrialization, the first 6G version of 3GPP is expected to appear around 2030, and there will be 3 to 4 more versions of evolution focusing on 5G enhancement technologies before that. At the 3GPP PCG#46-e meeting held in April 2021, the industry unanimously agreed to name Rel-18 and subsequent versions "5G-Advanced".
[0091] As the second stage of 5G evolution, the industry will be committed to further exploring the potential of 5G networks to provide a more advanced communication experience and adapt to more application scenarios in vertical industries, aiming to meet market demand around 2025.
[0092] Enhanced networks based on 5G-Advanced can both maintain industry prosperity and narrow the gap with the 6G vision. In fact, many research directions that are currently being hotly debated in academia have not deviated from the design architecture of 5G. Therefore, some more mature technologies are more suitable to be included in the standardization scope of 5G-Advanced.
[0093] The evolution of wireless network standards is a gradual process. Each new version contains both continuation of old issues and the coexistence of new ones. For example, while the standardization focus after Rel-15 was on 5G NR, LTE continued to evolve at the same time. This coexistence can be expected to continue in the early stages of 5G-Advanced: on the one hand, there will be issues carried over from Rel-17, such as MIMO enhancement, network energy saving, XR enhancement, NTN enhancement, sidelink and positioning, and the integration of unlicensed spectrum; on the other hand, 5G-Advanced needs to explore more application scenarios in vertical industries, expanding network performance from multiple dimensions to better meet the actual market demands of the coming years.
[0094] Specifically, when the first base station is a 5G base station and the second base station is a 5G+ base station, it can be assumed that the 5G base station has 8 downlink reference signal beams, that is, the first signal beam. Among them, the first signal beam is BFx0, BFx1, BFx2, ... BFx7.
[0095] The 5G+ base station has 64 downlink reference signal beams, also known as the second signal beams, namely BFy0, BFy1, BFy2, ... BFy63.
[0096] When the second base station is a 6G base station, the number of downlink reference signal beams can be set to be equal to or greater than 64 according to the requirements and settings of 6G technology. This exemplary embodiment does not impose any special limitations on this.
[0097] Among them, BF (Beam Form) refers to beamforming. The simplest way to form a beam is to array multiple antennas. There are many ways to align these antenna elements, but one of the simplest methods is to align the antennas along a line.
[0098] By adjusting the antenna azimuth and downtilt angles of the 5G base station or 5G+ base station respectively, and by adjusting the weights of the digital or analog beams of the 5G base station or 5G+ base station respectively, the first signal beam of the 5G base station and the second signal beam of the 5G+ base station can be designed into the beam mapping relationship shown in Table 1:
[0099]
[0100]
[0101] Table 1
[0102] Specifically, when the first signal beam of the 5G base station is BFx0, the second signal beam of the corresponding 5G+ base station is BFy0~BFy7; when the first signal beam of the 5G base station is BFx1, the second signal beam of the corresponding 5G+ base station is BFy8~BFy15; ...; when the first signal beam of the 5G base station is BFxi, the second signal beam of the corresponding 5G+ base station is BFy8i~BFy(8i+7); ...; when the first signal beam of the 5G base station is BFx7, the second signal beam of the corresponding 5G+ base station is BFy56~BFy63.
[0103] It is worth noting that the mapping relationship between the first signal beam and the second signal beam can be adjusted and changed depending on the application scenario.
[0104] In step S120, if the multimode terminal meets the preset conditions, the target access beam in the second signal beam corresponding to the current access beam in the first signal beam is determined according to the mapping relationship.
[0105] In an exemplary embodiment of this disclosure, the current access beam for the multimode terminal is determined by beam scanning of the first base station, and random access is initiated to the first base station through the current access beam.
[0106] In an optional embodiment, Figure 2 A flowchart illustrating the method for accessing the first base station is shown, as follows: Figure 2 As shown, the method includes at least the following steps: In step S210, the first signal beam of the first base station is subjected to beam scanning processing to obtain the first strongest beam, and the first strongest beam is determined as the current access beam.
[0107] This multi-mode terminal is the user equipment (UE).
[0108] For example, the user equipment determines the strongest beam by scanning the beams of the 5G base station and selecting the one with the highest RSRP (Reference Signal Receiving Power) among the eight first signal beams of the 5G base station.
[0109] Among them, RSRP is a key parameter in LTE networks that can represent the strength of wireless signals and is one of the physical layer measurement requirements. It is the average value of the signal power received on all REs (resource particles) carrying the reference signal within a certain symbol.
[0110] After determining the first strongest beam, this first strongest beam can be designated as the current access beam of the first base station. Furthermore, the user equipment can also record the 5G beam BFxi, which is the strongest downlink reference signal of the 5G base station, i.e., the current access beam.
[0111] In step S220, random access is initiated to the first base station through the current access beam so that the first base station responds.
[0112] After the current access beam is determined, it can be used to access the first base station, such as a 5G base station.
[0113] Specifically, the user equipment initiates random access to the 5G base station via the 5G PRACH (Physical Random Access Channel) in the direction of the BFxi beam, causing the first base station to respond and execute 5G services. The random access initiated by the user equipment is achieved by sending a random access preamble sequence on the PRACH channel.
[0114] In this exemplary embodiment, the first base station is accessed by performing beam scanning processing on the first signal beam. The access method is simple, accurate, and easy to implement, and can well support the service processing needs of the first base station.
[0115] Furthermore, when the traffic volume of the multi-mode terminal meets preset conditions, the target access beam can be determined to provide data support for accessing the second base station.
[0116] In an optional embodiment, Figure 3 A flowchart illustrating the method for determining the target access beam is shown, such as... Figure 3 As shown, the method includes at least the following steps: In step S310, the current traffic volume of the multi-mode terminal and the traffic volume threshold corresponding to the current traffic volume are obtained, and the current traffic volume and the traffic volume threshold are compared to obtain a comparison result.
[0117] Specifically, the current traffic volume can be determined by monitoring the traffic volume of the multi-mode terminal in real time, or by periodically monitoring the traffic volume of the multi-mode terminal at preset time intervals. Alternatively, other methods for obtaining the current traffic volume of the multi-mode terminal can be set according to actual needs; this exemplary embodiment does not impose any special limitations on these methods.
[0118] Furthermore, a business volume threshold corresponding to the business volume can also be obtained. This business volume threshold can be set according to the actual situation, and this exemplary embodiment does not impose any special limitations on it.
[0119] After obtaining the current business volume and the business volume threshold, the current business volume can be compared with the business volume threshold to obtain the corresponding comparison result.
[0120] In step S320, if the comparison result is that the current traffic volume is greater than the traffic volume threshold, the target access beam in the second signal beam corresponding to the current access beam in the first signal beam is determined according to the mapping relationship.
[0121] When the comparison between the current traffic volume and the traffic volume threshold shows that the current traffic volume is greater than the traffic volume threshold, it indicates that a second base station carrier, such as a 5G+ carrier, needs to be added.
[0122] Therefore, when a user equipment detects a downlink reference signal from a second base station, such as a 5G+ downlink reference signal, it can determine the target access beam corresponding to the current access beam based on the established mapping relationship between the first signal beam and the second signal beam.
[0123] In an optional embodiment, Figure 4 A flowchart illustrating the method for further determining the target access beam is shown, such as... Figure 4 As shown, the method includes at least the following steps: In step S410, the beam range corresponding to the current access beam of the first signal beam is determined in the second signal beam according to the mapping relationship.
[0124] Since the mapping relationship between the first signal beam and the second signal beam is a one-to-many mapping relationship, after determining the current access beam, it is necessary to first determine the beam range of one of the second signal beams corresponding to the current access beam.
[0125] Based on the beam mapping relationship between 5G base stations and 5G+ base stations in Table 1, when the current access beam of the 5G base station is BFxi, the corresponding 8 beams BFy8i~BFy(8i+7) can be determined.
[0126] For example, when the current access beam is BFx0, the beam range that can be determined according to this mapping relationship is BFy0~BFy7.
[0127] In step S420, beam scanning is performed within the beam range to obtain the second strongest beam, and the second strongest beam is determined to be the target access beam in the second signal beam.
[0128] Because 5G+ base stations have narrower beams, more detailed and precise retrieval is required. Therefore, when receiving a small beam range of 8 BFy8i to BFy(8i+7), the 5G+ beam with the strongest downlink reference signal can be quickly detected.
[0129] Specifically, user equipment can determine the second strongest beam within the beam range of a 5G+ base station by performing beam scanning processing. This second strongest beam is the one with the highest RSRP within the beam range.
[0130] Therefore, the second strongest beam is the target access beam in the second signal beam that corresponds to the current access beam.
[0131] In this exemplary embodiment, the beam range corresponding to the current access beam is determined by the mapping relationship, and then the target access beam is scanned within the beam range. This eliminates the need for beam scanning and detection within a large range of second signal beams, shortens the time for determining the target access beam, and improves the speed and efficiency of accessing the second base station.
[0132] In addition, if the comparison result between the current traffic volume and the traffic volume threshold is not greater than the traffic volume threshold, the operation of the first base station, such as the 5G carrier mode, can continue.
[0133] In an optional embodiment, if the comparison result is that the current traffic volume is less than or equal to the traffic volume threshold, the system continues to access the first base station through the current access beam so that the first base station can respond.
[0134] When the comparison between the current traffic volume and the traffic volume threshold shows that the current traffic volume is less than or equal to the traffic volume threshold, the multi-mode terminal can continue to initiate random access to the 5G base station through the 5G PRA CH channel in the direction of the BFxi beam, so that the first base station responds and continues to execute 5G services.
[0135] In step S130, the second base station is accessed through the target access beam so that the second base station responds.
[0136] In an exemplary embodiment of this disclosure, after the target access beam is determined, the multimode terminal can access the second base station through the target access beam.
[0137] In an optional embodiment, random access is initiated to the second base station via the target access beam, so that the second base station responds to the target access beam.
[0138] After the target access beam is determined, an indication signal corresponding to the target access beam can be generated to access the second base station.
[0139] In an optional embodiment, Figure 5 A flowchart illustrating the method for accessing a second base station is shown, such as... Figure 5 As shown, the method includes at least the following steps: in step S510, an indication signal corresponding to the target access beam is generated, and the indication signal is transmitted to the second base station through the first base station.
[0140] The indication signal can be the target access beam BFyj.
[0141] The multi-mode terminal transmits the indication signal BFyj of the strongest target access beam of the 5G+ base station to the first base station (e.g., the 5G base station) via a link to the first base station. The first base station then transmits the indication signal BFyj to the second base station.
[0142] It is worth noting that the second base station receives signals through a beam decision unit.
[0143] In step S520, random access is initiated to the second base station through the target access beam, so that the second base station responds to the target access beam according to the indication signal.
[0144] After receiving the indication signal, the beam decision-maker of the second base station, such as the 5G+ base station, can adjust the direction of the receiving beam and quickly point it toward the direction of the target access beam corresponding to the beam of the indication signal BFyj.
[0145] Therefore, user equipment can initiate random access to the second base station through the target access beam, and the second base station can respond quickly to the user equipment's 5G+ random access, such as through a fast RAR (Random Access Response) response. Furthermore, based on 5G / 5G+ joint operation methods, such as MRDC (Multi-RAT Dual Connectivity) or CA (Carrier Aggregation), high-capacity services can be quickly implemented.
[0146] In this exemplary embodiment, by generating an indication signal corresponding to the target access beam, the information of the target access beam is transmitted from the first base station to the second base station through the beam decision-maker. This eliminates the need for the second base station to perform extensive scanning, detection, and decision-making, saving the decision-making time of the second base station and achieving the goal of rapid determination and response of the target access beam of the second base station.
[0147] The beam determination method in this embodiment will be described in detail below with reference to an application scenario.
[0148] Figure 6 A flowchart illustrating the beam determination method in an application scenario is shown, such as... Figure 6 As shown, in step S610, the 5G / 5G+ base station is powered on and initialized.
[0149] With the development of mobile communication technology, more and more new types of networks have emerged, such as Time Division Synchronous Code Division Multiple Access (TDMA) networks and Long Term Evolution (LTE) networks. New networks face the problem of insufficient coverage in the early stages of deployment, and in the later stages, they face the challenge of interoperability with existing networks, such as the Global System for Mobile Communications (GSM).
[0150] Currently, multi-mode terminals are primarily used to enable operation between different network systems. Typically, a newer network is designated as the preferred network for the multi-mode terminal; that is, after powering on, the terminal preferentially resides on the newer network. If it is detected that the newer network cannot be used due to signal quality degradation or other reasons, an inter-system switch is initiated to revert to the existing network. Furthermore, with continuous optimization of parameters and mechanisms, the success rate of inter-system handover has been significantly improved.
[0151] Correspondingly, the multi-mode terminal can access a dual-mode base station or a multi-mode base station. For example, a dual-mode base station can be a 5G / 5G+ base station or a 5G / 6G base station, and a multi-mode base station can be a 5G / 5G+ / 6G base station. In addition, with the development and updating of communication technology, dual-mode base stations or multi-mode base stations can also be other types of base stations, and this exemplary embodiment does not impose any special limitations on them.
[0152] Among them, 5G+ stands for 5G Advanced.
[0153] With the release of the first 5G NR standard version (Rel-15) in 2019, the global industrialization of 5G has begun on a large scale. Statistics show that by 2020, 5G base stations had been deployed in all prefecture-level cities and some county-level cities in China, and 5G mobile phone shipments in China alone exceeded 150 million units in 2020. As the basic version of NR, Rel-15 primarily targets traditional eMBB services. In the subsequent Rel-16 and Rel-17 evolution versions, 3GPP (3rd Generation Partnership Project) further explored more vertical industry applications and support, and improved the 5G network in multiple ways from the following dimensions.
[0154] 3GPP is a collaborative project within the mobile communications industry, primarily aimed at organizing the development and management of mobile communication standards. In the 5G field, 3GPP is responsible for managing the continuously evolving 5G standards.
[0155] The first is greater spectrum and bandwidth utilization, such as the 52.6–71 GHz millimeter wave band; the second is support for industrial internet applications, which can be considered an enhancement of URLLC scenarios to meet the low latency and high reliability requirements in industrial applications; the third is support for more types of terminal devices, such as wearable devices, video surveillance, wireless sensors, virtual / augmented reality, etc.; the fourth is more diverse network forms, such as vehicle-to-everything (V2X), non-terrestrial networks, and integrated access and backhaul.
[0156] Wireless communication networks are typically updated every ten years. With the large-scale deployment of 5G base stations and the widespread adoption of user terminals, people are increasingly anticipating the new applications and experiences that next-generation communication technologies will bring. Recently, the IMT-2030 organization released a white paper on the overall vision and potential key technologies for 6G, which identified some popular research directions, such as artificial intelligence, immersive cloud XR, integrated air-space-ground communication, integrated communication and sensing, holographic communication, digital twins, terahertz and visible light communication, etc.
[0157] From the perspective of standards evolution and industrialization, the first 6G version of 3GPP is expected to appear around 2030, and there will be 3 to 4 more versions of evolution focusing on 5G enhancement technologies before that. At the 3GPP PCG#46-e meeting held in April 2021, the industry unanimously agreed to name Rel-18 and subsequent versions "5G-Advanced".
[0158] As the second stage of 5G evolution, the industry will be committed to further exploring the potential of 5G networks to provide a more advanced communication experience and adapt to more application scenarios in vertical industries, aiming to meet market demand around 2025.
[0159] Enhanced networks based on 5G-Advanced can both maintain industry prosperity and narrow the gap with the 6G vision. In fact, many research directions that are currently being hotly debated in academia have not deviated from the design architecture of 5G. Therefore, some more mature technologies are more suitable to be included in the standardization scope of 5G-Advanced.
[0160] The evolution of wireless network standards is a gradual process. Each new version contains both continuation of old issues and the coexistence of new ones. For example, while the standardization focus after Rel-15 was on 5G NR, LTE continued to evolve at the same time. This coexistence can be expected to continue in the early stages of 5G-Advanced: on the one hand, there will be issues carried over from Rel-17, such as MIMO enhancement, network energy saving, XR enhancement, NTN enhancement, sidelink and positioning, and the integration of unlicensed spectrum; on the other hand, 5G-Advanced needs to explore more application scenarios in vertical industries, expanding network performance from multiple dimensions to better meet the actual market demands of the coming years.
[0161] The multi-mode terminal can access a dual-mode base station or a multi-mode base station. For example, a dual-mode base station can be a 5G / 5G+ base station or a 5G / 6G base station, and a multi-mode base station can be a 5G / 5G+ / 6G base station. In addition, with the development and updating of communication technology, dual-mode base stations or multi-mode base stations can also be other types of base stations, and this exemplary embodiment does not impose any special limitations on them.
[0162] The first base station can be a 5G base station, and the second base station can be a 5G+ base station. 5G+ stands for 5G Advanced.
[0163] In step S620, the 5G / 5G+ multi-mode terminal randomly accesses the 5G base station through 5G beam scanning, and the multi-mode terminal records the access beam BFxi.
[0164] The current access beam BFxi of the multi-mode terminal is determined by beam scanning of the 5G base station, and random access is initiated to the 5G base station through the current access beam BFxi.
[0165] Specifically, the first signal beam of the 5G base station is subjected to beam scanning processing to obtain the first strongest beam, and the first strongest beam is determined as the current access beam.
[0166] This multi-mode terminal is the user equipment. The user equipment determines the strongest beam from the eight first signal beams of the 5G base station by scanning the beams of the 5G base station.
[0167] Among them, RSRP is a key parameter in LTE networks that can represent the strength of wireless signals and is one of the physical layer measurement requirements. It is the average signal power received on all REs carrying the reference signal within a certain symbol.
[0168] After determining the first strongest beam, this first strongest beam can be designated as the current access beam of the 5G base station. Furthermore, the user equipment can also record the 5G beam BFxi, which is the strongest downlink reference signal of the 5G base station, i.e., the current access beam.
[0169] Initiate random access to the 5G base station through the current access beam to enable the 5G base station to respond.
[0170] After the current access beam is determined, it can be used to access the first base station, such as a 5G base station.
[0171] Specifically, the user equipment initiates random access to the 5G base station via the 5G PRACH channel in the direction of the BFxi beam, causing the 5G base station to respond and execute 5G services. Random access initiated by the user equipment is achieved by sending a random access preamble sequence on the PRACH channel.
[0172] By performing beam scanning processing on the first signal beam to access the 5G base station, the access method is simple, accurate, and easy to implement, and can well support the service processing needs of the 5G base station.
[0173] Here, BF stands for beamforming. The simplest way to form a beam is to array multiple antennas. There are many ways to align these antenna elements, but one of the simplest methods is to align the antennas along a line.
[0174] In step S630, is the multi-mode terminal service volume greater than the threshold?
[0175] When the traffic volume of the multi-mode terminal meets the preset conditions, the target access beam is determined to provide data support for accessing the 5G+ base station.
[0176] Obtain the current traffic volume of the multi-mode terminal and the corresponding traffic volume threshold, and compare the current traffic volume and the traffic volume threshold to obtain the comparison result.
[0177] Specifically, the current traffic volume can be determined by monitoring the traffic volume of the multi-mode terminal in real time, or by periodically monitoring the traffic volume of the multi-mode terminal at preset time intervals. Alternatively, other methods for obtaining the current traffic volume of the multi-mode terminal can be set according to actual needs; this exemplary embodiment does not impose any special limitations on these methods.
[0178] Furthermore, a business volume threshold corresponding to the business volume can also be obtained. This business volume threshold can be set according to the actual situation, and this exemplary embodiment does not impose any special limitations on it.
[0179] After obtaining the current business volume and the business volume threshold, the current business volume can be compared with the business volume threshold to obtain the corresponding comparison result.
[0180] In step S640, the 5G single-carrier operating mode is used.
[0181] If the comparison result shows that the current traffic volume is less than or equal to the traffic volume threshold, continue to access the 5G base station through the current access beam so that the 5G base station can respond.
[0182] When the comparison between the current traffic volume and the traffic volume threshold shows that the current traffic volume is less than or equal to the traffic volume threshold, the multi-mode terminal can continue to initiate random access to the 5G base station through the 5G PRA CH channel in the direction of the BFxi beam, so that the 5G base station can respond and continue to execute 5G services.
[0183] In step S650, the 5G+ downlink reference signal is detected.
[0184] If the comparison result shows that the current traffic volume is greater than the traffic volume threshold, the target access beam in the second signal beam corresponding to the current access beam in the first signal beam is determined according to the mapping relationship.
[0185] When the comparison between the current traffic volume and the traffic volume threshold shows that the current traffic volume is greater than the traffic volume threshold, it indicates that a 5G+ carrier needs to be added.
[0186] Therefore, when a user equipment detects a downlink reference signal from a 5G+ base station, such as a 5G+ downlink reference signal, it can determine the target access beam corresponding to the current access beam based on the established mapping relationship between the first signal beam and the second signal beam.
[0187] In step S660, the 8 beams corresponding to BFxi are found from the 5G / 5G+ beam mapping relationship, and the beam indicator BFyj with the strongest 5G+ signal is quickly detected.
[0188] Acquire the first signal beam of the first base station and the second signal beam of the second base station, and establish a mapping relationship between the first signal beam and the second signal beam.
[0189] Specifically, when the first base station is a 5G base station and the second base station is a 5G+ base station, it can be assumed that the 5G base station has 8 downlink reference signal beams, i.e., the first signal beams. These first signal beams are BFx0, BFx1, BFx2, ..., BFx7. The 5G+ base station has 64 downlink reference signal beams, i.e., the second signal beams, which are BFy0, BFy1, BFy2, ..., BFy63.
[0190] By adjusting the antenna azimuth and downtilt angles of the 5G base station or the 5G+ base station respectively, and by adjusting the weights of the digital or analog beams of the 5G base station or the 5G+ base station respectively, the first signal beam of the 5G base station and the second signal beam of the 5G+ base station can be designed into the beam mapping relationship shown in Table 1.
[0191] Specifically, when the first signal beam of the 5G base station is BFx0, the second signal beam of the corresponding 5G+ base station is BFy0~BFy7; when the first signal beam of the 5G base station is BFx1, the second signal beam of the corresponding 5G+ base station is BFy8~BFy15; ...; when the first signal beam of the 5G base station is BFxi, the second signal beam of the corresponding 5G+ base station is BFy8i~BFy(8i+7); ...; when the first signal beam of the 5G base station is BFx7, the second signal beam of the corresponding 5G+ base station is BFy56~BFy63.
[0192] It is worth noting that the mapping relationship between the first signal beam and the second signal beam can be adjusted and changed depending on the application scenario.
[0193] Based on the mapping relationship, the beam range corresponding to the current access beam of the first signal beam is determined in the second signal beam.
[0194] Since the mapping relationship between the first signal beam and the second signal beam is a one-to-many mapping relationship, after determining the current access beam, it is necessary to first determine the beam range of one of the second signal beams corresponding to the current access beam.
[0195] Based on the beam mapping relationship between 5G base stations and 5G+ base stations in Table 1, when the current access beam of the 5G base station is BFxi, the corresponding 8 beams BFy8i~BFy(8i+7) can be determined.
[0196] For example, when the current access beam is BFx0, the beam range that can be determined according to this mapping relationship is BFy0~BFy7.
[0197] Beam scanning is performed within the beam range to obtain the second strongest beam, and the second strongest beam is determined as the target access beam in the second signal beam.
[0198] Because 5G+ base stations have narrower beams, more detailed and precise retrieval is required. Therefore, when receiving a small beam range of 8 BFy8i to BFy(8i+7), the 5G+ beam with the strongest downlink reference signal can be quickly detected.
[0199] Specifically, user equipment can determine the second strongest beam within the beam range of a 5G+ base station by performing beam scanning processing. This second strongest beam is the one with the highest RSRP within the beam range.
[0200] Therefore, the second strongest beam is the target access beam in the second signal beam that corresponds to the current access beam.
[0201] The beam range corresponding to the current access beam is determined by the mapping relationship, and then the target access beam is scanned within the beam range. This eliminates the need for beam scanning and detection within a large range of second signal beams, shortens the time for determining the target access beam, and improves the speed and efficiency of accessing the second base station.
[0202] In step S670, the multi-mode terminal transmits the 5G+ strongest beam indication BFyj to the 5G base station via the 5G link, and then forwards it to the 5G+ base station beam decision-maker.
[0203] After the target access beam is determined, the multi-mode terminal can access the 5G+ base station through the target access beam.
[0204] Random access is initiated to the 5G+ base station through the target access beam, so that the 5G+ base station responds to the target access beam.
[0205] After the target access beam is determined, an indication signal corresponding to the target access beam can be generated to access the 5G+ base station.
[0206] Generate an indication signal corresponding to the target access beam and transmit the indication signal to the 5G+ base station via the 5G base station.
[0207] The indication signal can be the target access beam BFyj.
[0208] The multi-mode terminal transmits the indication signal BFyj of the strongest target access beam of the 5G+ base station to the 5G base station via a link from the 5G base station, such as a 5G link. The 5G base station then transmits the indication signal BFyj to the 5G+ base station.
[0209] It is worth noting that 5G+ base stations receive signals through the beam decision unit of the 5G+ base station.
[0210] Figure 7 The diagram illustrates the structure of a multi-mode base station and beam decision unit in an application scenario, as shown below. Figure 7 As shown, this beam decision unit is added to the multi-mode base station. Furthermore, the beam decision unit can receive indication signals of the target access beam from the 5G+ or 6G base station and use them to quickly determine the direction of the access beam of the 5G+ or 6G base station.
[0211] In step S680, the multi-mode terminal initiates random access to the 5G+ base station via the 5G+PRACH channel in the direction of the BFyj beam.
[0212] In step S690, the 5G+ base station beam decision-maker causes the 5G+ base station receiving beam direction to immediately point to the direction corresponding to the BFyj beam, performs a fast RAR response to the 5G+ random access beam of the multi-mode terminal, and quickly performs high-capacity services in the 5G / 5G+ joint working mode.
[0213] Random access is initiated to the 5G+ base station through the target access beam, so that the 5G+ base station responds to the target access beam according to the indication signal.
[0214] After receiving the indication signal, the beam decision-maker of the 5G+ base station can adjust the direction of the receiving beam and quickly point it toward the direction of the target access beam corresponding to the indication signal BFyj beam.
[0215] Therefore, user equipment can initiate random access to the 5G+ base station through the target access beam, and the second base station can respond quickly to the user equipment's 5G+ random access, such as through a fast RAR response. Furthermore, based on 5G / 5G+ joint operation, high-capacity services can be rapidly implemented through methods such as MRDC or CA.
[0216] By generating an indication signal corresponding to the target access beam, the information of the target access beam is transmitted from the 5G base station to the 5G+ base station through the beam decision-maker. This eliminates the need for the 5G+ base station to scan, detect, and make decisions over a wide range of 64 beams from BFy0 to BFy63, saving the 5G+ base station's scanning, detection, and decision-making time. This achieves the goal of rapid determination and response of the target access beam for the 5G+ base station.
[0217] The beam determination method in this application scenario establishes a mapping relationship between the first signal beam of the first base station and the second signal beam of the second base station, providing a data foundation and theoretical support for determining the target access beam. Furthermore, by determining the target access beam based on the mapping relationship and the current access beam, beam scanning and detection over a wide area of the second signal beam are eliminated, narrowing the detection range for determining the target access beam, shortening the detection time of the target access beam for the second base station, and improving the speed and efficiency of the second base station's access beam detection. Moreover, accessing the second base station via the target access beam saves time in beam scanning, beam detection, and beam decision-making, achieving rapid access to the second base station and rapid reception of its response. In addition, it further optimizes peak speed and user experience, improves the network performance of multi-mode terminals, and is conducive to the continued evolution towards 5G+ and 6G technologies, possessing very broad application prospects.
[0218] The embodiments disclosed herein effectively solve the problems of long scanning time and large access latency of 5G+ (6G) access beams in 5G / 5G+ (6G) multi-mode terminals, and are highly targeted towards the evolution of networks towards 5G+ and 6G. Furthermore, they significantly improve the completeness of 5G+ and 6G access network solutions and enhance network performance. In addition, only the target access beam indication signal and beam decision unit need to be added, requiring minimal modifications to 5G+ and 6G base stations, resulting in low implementation complexity and ease of system implementation and solution promotion.
[0219] Among them, the target access beam indication signal is transmitted by the user equipment to the 5G base station through the 5G link, indicating the strongest target access beam of 5G+ or 6G.
[0220] The beam decision unit can receive the indication signal of the strongest target access beam of 5G+ or 6G sent by the 5G base station and use it to quickly determine the direction of the 5G+ or 6G base station access beam.
[0221] From all perspectives, this reduces the beam scanning range of 5G+(6G) on the multi-mode terminal side and shortens the beam detection time. It also eliminates the beam scanning, detection, and decision-making time on the 5G / 5G+(6G) base station side, enabling rapid determination and response of the 5G+(6G) access beam. Specifically, by rapidly transmitting the indication signal of the strongest target access beam of 5G+(6G) to the beam decision-maker of the 5G+(6G) base station via the 5G link, it facilitates rapid decision-making and determination of the access beam direction. Furthermore, it improves the network performance of 5G+(6G) and optimizes the user experience.
[0222] Furthermore, in an exemplary embodiment of this disclosure, a beamforming device is also provided, applied to a multimode terminal. Figure 8 A schematic diagram of the beamforming device is shown, such as... Figure 8 As shown, the beamforming device 800 may include: a relationship establishment module 810, a beamforming module 820, and an access base station module 830. Wherein:

[0232] In one exemplary embodiment of the present invention, the method further includes:
