BEAM BASED ARCHITECTURE IN 6G NETWORKSCROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to Indian Provisional Application No. 202541009406, filed on February 5, 2025, and Indian Non-Provisional Application No. 202541009406, filed on October 8, 2025, the entire contents of which are incorporated herein by reference.FIELD
[0002] The present disclosure relates to beam-based architecture of Sixth Generation (6G) network.BACKGROUND
[0003] In Third Generation Partnership Project (3 GPP), a Radio Access Network (RAN) is introduced as a part of a mobile network that manages wireless communication between User Equipment (UEs) (such as smartphones) and a core network. The RAN handles all radio-related functions within one or more cells, acting as an interface between wireless UEs and the core network. The RAN provides an access to, and coordinates management of resources across radio sites. A single UE may be connected to multiple RANs at the same time. The RAN essentially manages the wireless link between devices and a network infrastructure.
[0004] Traditional RANs are often built with proprietary hardware and software from a single vendor. An implementation of the RAN may follow an Open-RAN (O-RAN) architecture, thatallows inter-operation between UEs provided by different vendors. The O-RAN promotes a disaggregation of RAN functionality into virtualized components, enabling greater flexibility and scalability. The O-RAN breaks down monolithic network system into smaller modular components, like Radio Units (RUs), Distributed Units (DUs), and Centralized Units (CUs).
[0005] Generally, UEs are wirelessly connected to a RAN using a concept of celsl. Physical layer resources, especially physical channels in DL and UL including shared / dedicated and common channels are managed at cell level. Both a cell and a beam may be defined as a certain geographical location that serves the UEs. The cell encompasses one or more beams, while a gNodeB (gNB) DU encompasses one or more cells and the gNB encompasses one or more gNB-DUs.
[0006] In the evolution of wireless communication, 6G networks are expected to move towards more sophisticated beamforming techniques, potentially blurring the lines between traditional cellbased systems and what's known as "cell-free" architecture. Instead of relying on fixed cellular coverage areas, 6G network is projected to leverage beams to establish direct and dynamic connections between base stations and individual users or devices.
[0007] Beamforming is a signal processing technique used to direct a transmission and / or a reception of signals in a specific direction using multiple antennas. The beamforming may be used in both Uplink (UL) and Downlink (DL) scenarios.
[0008] The information disclosed in this background of the disclosure section is only for enhancement of understanding of the general background of the disclosure and should not be takenas acknowledgment or any form of suggestion that this information forms prior art already known to a person skilled in the art.SUMMARY

[0022] The foregoing disclosure provides illustration and description but is not intended to be exhaustive or to limit the implementations to the precise form disclosed. Modifications and variations are possible in light of the above disclosure or may be acquired from practice of the implementations.
[0023] Wireless communication systems from the First Generation (1G) to the Fifth Generation (5G) have a cell-based network architecture. Procedures such as handover in cell-based networks may be complex and disruptive. The handover procedure may require multiple signaling exchanges between a User Equipment (UE) and a Base Station (BS) that may lead to delays,service interruptions, or dropped calls. Additional limitations may include signal quality issues at cell edges, due to weak signals or interference. In large cells, signals may be dispersed due to a long propagation path and may be buried under background noise at a receiver. Conversely, in small cells, interference from signals intended for other UEs in neighboring cells can significantly affect the reception of useful signals. In some cases, imperfections in a geographical shape of cells may also lead to potential coverage gaps, thus affecting the connection of the UE with the BS for communication.
[0024] Further, reliance on handovers to transition the UE between cells during UE mobility is a complex process involving multiple signaling between the UE and the BSs of both source and target cells, introducing a delay in handover. Thus, causing disruptions that may negatively impact a user experience.
[0025] Therefore, Sixth Generation (6G) networks are moving towards beamforming techniques, i.e., they are evolving from cell-based networks to "cell-free" architectures i.e., beam-based architecture. Instead of relying on fixed cellular coverage areas, 6G is projected to leverage beams to establish direct and dynamic connections between BSs and individual users or devices. This beam-based architecture / beam-based network overcomes the above-mentioned limitations ensuring improved communication networks.
[0026] It may be noted that, for convenience of explanation, the disclosure uses terms and names defined in the 3rd Generation Partnership Project Radio Access Network (3GPP RAN) standards. More specifically, the terms, such as, but not limited to, ‘RACH’, ‘RRC IDLE’, ‘RRC Inactive’,‘RRC CONNECTED’, ‘handover’, ‘Downlink (DL)’, ‘Uplink (UL)’, ‘Scheduling Request (SR)’, ‘RSRP’, to be interpreted as specified by the 3GPP RAN standards.
[0027] Conventionally, beamforming requires the network to obtain Channel State Information (CSI) from the UE. For effective network coordination, the CSI and user data must be exchanged between cells, often situated at different locations. Although beamforming within individual cells is widely used, network coordination remains underutilized. In one case, when a UE moves across multiple sites, it may primarily connect to one cell at a time, leading to a frequent handover rate for high mobility UEs. However, if the UE is not tied to a specific cell, the handover process would be less complex, and mobility management would be simplified. In another case, coverage uniformity may be enhanced through Coherent Joint Transmission (CJT) and Coherent Joint Reception (CJR) with the help of configuring UEs with multiple Transmission Reception Points (TRPs). However, dividing the TRPs into groups associated with different cells may impede their coordination in CJT and CJR.
[0028] Though the cellular structure has been well established due to Radio Access Network (RAN) architecture with many autonomous BSs, however, with advancements in technologies such as cloud computing and ultra-high-speed, large-bandwidth wired connectivity, independent control of the BSs needs to be reconsidered. Additionally, approaches such as, a Software-Defined Networking (SDN) approach reduces dependency between a control of radio resources and the user data transferred between the network and UEs. Therefore, the wireless network structure may be redesigned to incorporate these new technological trends and architectures.
[0029] Fig. 1 illustrates an exemplary representation of an environment 100 related to wireless communication, in which some embodiments of the present disclosure may be implemented.
[0030] The environment 100 exemplarily depicts a Next Generation Radio Access Network (NG-RAN) node 102, a User Equipment (UE) 104 and a communication network 106. Some examples of the UE 104 may include, but not limited to, electronic devices such as, a smartphone, a laptop, a desktop, a personal computer, or any spatial computing device capable of performing wireless communication. For example, the UE 104 may work on multiple platforms and / or Operating Systems to perform different operations related to wireless communication. In an exemplary scenario, the UE 104 may initiate a connection with a NG RAN node 102 for one or more conditions. For example, the one or more conditions may include, but is not limited to, initial access of the NG RAN node 102 from RRC IDLE, transition from RRC INACTIVE to RRC CONNECTED, RRC connection re-establishment, handover, beam failure recovery, synchronous reconfiguration, timing alignment during Secondary cell (Scell) addition, Downlink (DL) out of sync, Uplink (UL) out of sync, Scheduling Request (SR), UL data arrival and on demand system information. It may be noted that the one or more conditions mentioned above are for exemplary purposes and the UE 104 may establish connection with the NG RAN node 102 based on other conditions as well.
[0031] The UE 104 may establish connection with the NG RAN node 102 via a communication network 106. It is understood that the UE 104 may be in operative communication with the communication network 106, such as the Internet, enabled by a network provider, also known as an Internet Service Provider (ISP). The UE 104 may be connected to the communication network106 using a wireless network. Some non-limiting examples of wireless networks may include, but not limited to, Wireless LAN (WLAN), cellular networks, Bluetooth or ZigBee networks, and the like.
[0032] The UE 104 transmits measurement reports to the NG RAN node 102. The operations performed by the UE 104 are explained in detail with reference to Fig. 2.
[0033] Fig. 2 illustrates a block diagram of a device 200, in accordance with some embodiments of the present disclosure. As shown in Fig. 2, the device 200 includes a processor 210, a memory 220, a storage component 230, an input component 240, an output component 250, a communication interface 260, and a bus 270.
[0034] The processor 210, as used herein, means any type of computational circuit that may comprise hardware elements and software elements. The processor 210 may be embodied as a multi-core processor, a single core processor, or a combination of one or more multi-core processors and / or one or more single core processors, a distributed processing system, or the like. The processor 210 may be a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), an Accelerated Processing Unit (APU), an Application-Specific Integrated Circuit (ASIC), or another type of processing component.
[0035] The memory 220 includes a non-transitory computer readable medium. The memory 220 includes a Random-Access Memory (RAM), a Read Only Memory (ROM), and / or another type of dynamic or static storage device (e.g., a flash memory, a magnetic memory, and / or an opticalmemory) that stores information and / or instructions for use by the processor 210. The memory 220 comprises machine-readable instructions which are executable by the processor 210. These machine-readable instructions when executed by the processor 210 cause the processor 210 to perform one or more method steps of an embodiment described.
[0036] Storage component 230 stores information and / or software related to the operation and use of the device 200. For example, storage component 230 may include a hard disk (e.g., a magnetic disk, an optical disk, a magneto-optic disk, and / or a solid-state disk), a compact disc (CD), a digital versatile disc (DVD), a floppy disk, a cartridge, a magnetic tape, and / or another type of non-transitory computer-readable medium, along with a corresponding drive.
[0037] Input component 240 is configured to receive information, such as user data. For example, the input component 240 may include, but not be limited to, a touch screen display, a keyboard, a keypad, a mouse, a button, a switch, and / or a microphone. Additionally, or alternatively, the input component 240 may include a sensor for sensing information (e.g., a global positioning system (GPS), an accelerometer, a gyroscope, and / or an actuator).
[0038] The output component 250 is configured to provide output information from the device 200. For example, the output component 250 may be, but not limited to, a display, a speaker, an instruction device to an external device, and / or one or more light-emitting diodes (LEDs).
[0039] Communication interface 260 is an interface that provides a communication connection to other devices, such as external devices and internal devices. The connection by the communicationinterface 260 can be a wired connection, a wireless connection, or a combination of wired and wireless connections, and can be a direct connection or an indirect connection via a communication network that exists between the device 200 and other devices. In other words, the standard of the communication interface 260 is not limited.
[0040] The bus 270 acts as an interconnect between the processor 210, the memory 220, the storage component 230, the input component 240, the output component 250, and the communication interface 260 of the device 200. The bus 270 may include a wired interconnection or a wireless interconnection.
[0041] The number and arrangement of components shown in Fig. 2 are provided as an example. In practice, the device 200 may include additional components, fewer components, different components, or differently arranged components than those shown in Fig. 2. Additionally, or alternatively, a set of components (e.g., one or more components) of the device 200 may perform one or more functions described as being performed by another set of components of the device 200. Further, one or more method steps described in any of the embodiments may be performed utilizing a plurality of devices 200 in communication with one another.
[0042] In an embodiment, the device 200 may be a network entity (hereafter referred to as network entity 200) such as, an NG RAN node, a RAN Intelligent Controller (RIC), and the like. The network entity 200 configures a coverage area of one or more NG-RAN nodes into one or more beams and / or beam groups. Each of the one or more NG-RAN nodes comprises one or more Transmission Reception Points (TRPs). As a trend of adding more antenna elements to the one ormore TRPs continues in 6G network, beamforming may be crucial for a next generation of wireless systems. In the 6G network, there may be no cells, instead, the network manages beams and beam-groups. Beams are logical entities that may not be tied to any physical network components, thus making the beams easy to be added or removed from the 6G network. The concept of NG-RAN nodes being composed of one or more gNB-DUs may be retained in the beam-based architecture.
[0043] Each beam in the one or more beam groups comprises a unique identifier. The unique identifier of each beam may be three orders of magnitude larger than a number of possible cell identifiers in New Radio (NR) network. For example, while the NR network may use 14 bits to identify a cell, the network entity 200 uses 24 bits to identify a beam uniquely, with 10 Least Significant Bits (LSB) reserved to identify a beam within a group of up to 1024 beams.
[0044] The one or more beam groups may be associated with one of: a same Transmission and Reception Point (TRP) and a distinct TRP. For example, consider beam groups 1, 2, 3, 4, 5, 6, wherein beam groups 1, 2 and 3 may belong to TRP1, beam group 4 may belong to TRP 2 and beam groups 5 and 6 may belong to TRP 3. The one or more beam groups may be created based on, a location, a frequency of the beams, antenna system in the TRP functioning the beam, coverage, resources shared, physical channels and their characteristics, available resources, common beam-specific RRC parameter configurations, and the like. For example, beams located in a same region may be grouped in a same beam group.
[0045] The network entity 200 determines a set of active beams for serving the UE 104, when the UE 104 is at a first position. The set of active beams serving the UE 104 in the first position is determined based on measurement reports sent by the UE 104.
[0046] The measurement reports are messages sent by the UE 104 to the network entity 200, detailing radio signal conditions of the beams it has measured. The network, in turn, uses this information to manage and associate a connection of the UE 104 with the active set of beams, optimize network performance, and facilitate mobility procedures The measurement reports are essential for the network entity 200 to perform one or more operations such as mobility management related functions, Radio Resource Management (RRM) functions, beam management, and the like. The UE 104 measures a quality of different signal beams in a network. The network entity 200 uses this information relating to the quality of different signal beams to determine a set of active beams for the UE 104, such that the UE 104 maintains a high signal quality while performing both transmission and reception.
[0047] Further, consider the UE 104 is moving from the first position towards a second position. The network entity 200 tracks a mobility of the UE 104 from the first position towards the second position. Further, the set of active beams serving the UE 104 is updated based on the tracking and the measurement reports from the UE 104, ensuring a communication between the UE 104 and the network entity 200 is not distorted. The updated set of active beams may be associated with one of: a same beam group and different beam groups, as that of the determined set of active beams. Further, the updated set of active beams may be associated with a different gNB-DU or different gNB. For example, consider the determined set of active beams {11, 12, 21, 23}, where beams 11and 12 may belong to a first beam group and beams 21 and 23 may belong to a second beam group. In this example, consider an updated set of active beams {11, 12, 21, 23, 24, 31}, where beam 31 belongs to a third beam group i.e., a different beam group from that of beams {11, 12, 21, 23}. However, beam 24 belongs to the same beam group of the determined set of active beams i.e., from the second beam group. In an embodiment, the set of active beams is updated based on an availability of radio resources. For example, consider the UE 104 is moving from X position to Y position. In this example, consider the UE 104 may utilize beams {11, 12, 13, 21, 22, 23, 24, 31 and 32} to ensure uninterrupted coverage while moving from the X position to the Y position. However, radio resources of beams 13, 22, 32 are not sufficient for accommodating operations of the UE 104. Therefore, the updated set of active beams {11, 12, 21, 23, 24, 31} are considered. Hence, the beam-based structure of the network allows the set of active beams serving the UE 104 to dynamically adapt to the mobility of the UE 104, while considering traffic demand and quality -of-service requirements over time. Moreover, the beam-group structure inspired by SDN and Network Function Virtualization (NFV) reduces dependencies between the beams that facilitate wireless connectivity and the hardware implementing them.
[0048] The set of active beams is part of a set of beams. The set of beams comprises the set of active beams and a set of candidate beams. The set of active beams may be used by the network entity 200 to transmit to or receive physical channels that carry user traffic data from the UE 104. The set of candidate beams may only be beams exclusively for transmitting downlink reference signals (i.e., “DL only”) or for both transmission and reception (i.e., ‘joint UL DL’).
[0049] In an embodiment, the network entity 200 configures the UE 104 to transmit Sounding Reference Signals (SRS) or to perform Channel State Information (CSI) reports for qualities of the set of active beams and the set of candidate beams based on the measurements of their associated Non-Zero-Power CSI Reference Signals (NZP CSI-RS). These measurements may either be network-triggered or event-based-triggered for example, during mobility of the UE 104. In another embodiment, the UE 104 may identify and measure new beams from a same or neighboring beam-group and report the identified beams and / or beam-groups to the network entity 200. The network entity 200 may consider the identified beams and / or beam-groups to update the set of active beams.
[0050] In one embodiment, the network entity 200 may continuously update the set of active beams by including one or more candidate from the set of candidate beams to the set of active beams. In another embodiment, new beams from the one or more beam groups are included to the set of active beams. In yet another implementation, one or more active beams from the set of active beams may be removed to obtain the updated set of active beams. For example, consider the set of active beams includes beams {11, 12, 21, 23}, the set of beams include beams{ll, 12, 13, 21, 22, 23, 24, 31}, the set of candidate beams includes beams {13, 22, 24}. In an implementation, the updated set of active beams may include beams {11, 12, 21, 23, 24, 31} i.e., including only the candidate beams {24, 31 } . In another implementation, the updated set of active beams may be { 11, 12, 21, 23, 24, 31, 32}, wherein beam {32} is a new beam. In yet another implementation, the updated set of active beams may include {11, 21, 24, 31}, wherein beams {12, 23} are removed. One or more beams are added or removed from the set of active beams serving the UE 104, based on the tracking and measurement reports received from the UE 104, to ensure uninterrupted connection of the UE 104 with the network. Therefore, efficiently managing mobility of the UE,ensuring there are no disruptions due to sudden changes in connections (i.e., moving from one beam to another). This is because turning ON and / or OFF of beams (i.e., removing and adding beams as active and candidate set of beams), which are logical entities, is easy. Hence, allowing for different levels of energy saving based on real-time traffic demand.
[0051] Furthermore, as radio channel properties are associated with beams and there is no dependency on Reference Signals (RSs), data collection is less complex, facilitating an application of Artificial Intelligence (AI)ZMachine Learning (ML) in beam based network.
[0052] Further, physical channels such as DL Physical Downlink Control Channel (PDCCH) / Physical Downlink Shared Channel (PDSCH), UL Physical Uplink Shared Channel (PUCCH) / Physical Uplink Shared Channel (PUSCH), Synchronization Signal-Physical Broadcast Channel (SS-PBCH), and the like, System Information Broadcast (SB1) and other identifiers associated with a cell may be associated with beam-groups. Similarly, the network may also determine whether the UE 104 performs a RACH procedure during mobility of the UE 104 based on a timing advance associated with the candidate beam.
[0053] Fig.3 illustrates mobility of a User Equipment (UE) from a first position towards a second position, in accordance with some embodiments of the present disclosure. Consider, the UE 104 is moving from a first position, i.e., position A to a second position, i.e., position B. Initially, the set of active beams serving the UE 104 may be beams {11, 12, 21, 23}. When the UE 104 starts to move towards the position B, the set of active beams may be updated to beams {11, 12, 21, 23, 24, 31, 32}. Similarly, based on the mobility of the UE 104, to ensure uninterrupted coverage whilemoving from the position A to the position B, the set of active beams may be continuously updated, thereby improving user experience.
[0054] Fig. 4 illustrates an exemplary flowchart 400 illustrating method steps for mobility management in a beam-based network, in accordance with an embodiment of the present disclosure.
[0055] As illustrated in Fig. 4, the method 400 may comprise one or more steps. The method 400 may be described in the general context of computer executable instructions. Generally, computer executable instructions can include routines, programs, objects, components, data structures, procedures, modules, and functions, which perform particular functions or implement particular abstract data types.
[0056] The order in which the method 400 are described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Additionally, individual blocks may be deleted from the methods without departing from the scope of the subject matter described herein. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof.
[0057] At block 402, the method 400 includes configuring a coverage area of the one or more NG-RAN nodes into one or more beam groups.
[0058] At block 404, the method 400 includes determining a set of active beams for serving the UE 104 at a first position, from the one or more beam groups. The set of active beams are associated with one of: a same beam group and distinct beam groups, of the one or more beam groups. The one or more beam groups are associated with one of: a same TRP and a distinct TRP. The one or more beam groups are created based on a location, a frequency of the beam, antenna system in a TRP functioning the beam, coverage, resources shared, physical channels and their characteristics, available resources, common beam-specific RRC parameter configurations, and the like. The set of active beams is part of a set of beams, wherein the set of beams comprises the set of active beams and a set of candidate beams.
[0059] At block 406, the method 400 includes tracking mobility of the UE 104 from the first position (A) towards a second position (B).
[0060] At block 408, the method 400 includes continuously updating the set of active beams serving the UE 104. The updated set of active beams is associated with one of: a same beam group and different beam groups, as that of the determined set of active beams. Continuously updating the set of active beams comprising at least one of: (1) including one or more candidate from a set of candidate beams, to the set of active beams; (2) including new beams from the one or more beam groups to the set of active beams; and (3) removing one or more active beams from the set of active beams.
