Abstract
Description
Technical Field
[0001] This disclosure relates to wireless communication nodes that support network slicing and wireless communication methods. Background Technology
[0002] The 3rd Generation Partnership Project (3GPP, registered trademark) standardized the 5th generation mobile communication system (also known as 5G, New Radio (NR), or Next Generation (NG)) and also standardized the next generation, known as Beyond 5G, 5G Evolution, or 6G (e.g., Non-Patent Document 1).
[0003] During the migration from 5G to 6G, we envision either deploying 6G as a secondary node (SN) in a dual-connectivity (DC) architecture with 5G, or deploying 6G independently. In particular, in the case of deploying 6G independently, from the perspective of ensuring coverage areas, it is desirable to prioritize the allocation of low-frequency bands such as the so-called Platinum Band to 6G.
[0004] During this migration phase from 5G to 6G, the idea is to apply Multi-RAT spectrum sharing (MRSS). MRSS, also known as Dynamic Spectrum Sharing (DSS), enables 5G and 6G cells to coexist within the same frequency band.
[0005] In addition, in 5G, network slices are introduced that divide the network into service units (slices) based on use cases, business models, etc., and optimize the performance required by each slice (e.g., non-patent literature 2).
[0006] Existing technical documents
[0007] Non-patent literature
[0008] Non-patent document 1: NTT DOCOMO, “DOCOMO 6G White Paper Version 5.0”, [online], November 2022, Internet <URL:https: / / www.docomo.ne.jp / binary / pdf / corporate / technology / whitepaper_6g / DOCOMO_6G_White_PaperJP_20221116.pdf>

[0010] However, during the migration from 5G to 6G, there is a challenge in implementing MRSS that takes into account the types of slices. For example, in 5G, wireless communication nodes such as gNBs can be composed of CUs (Central Units) and one or more DUs (Distributed Units), and it is considered that the same structure should be followed in 6G.
[0011] In this situation, it is not possible to directly perform communication between specific wireless communication nodes that follow 5G and specific wireless communication nodes that follow 6G, and it is not possible to achieve load distribution or frequency band (band) distribution between nodes by utilizing MRSS, etc., while avoiding the increase in processing load and complexity.
[0012] Therefore, the following disclosure is made in view of the following situation, and its purpose is to provide a wireless communication node and wireless communication method that can realize load distribution or frequency band (band) distribution between nodes utilizing MRSS, etc., between 5G RAN (Radio Access Network) and 6G RAN while avoiding the increase in processing load and complexity.

[0014] One aspect of this disclosure is a wireless communication node comprising: a receiving unit that receives resource status information relating to the usage status of wireless resources in at least a logical unit segmented according to required performance or conditions, using a learning model, from other wireless communication nodes included in a first wireless access network; and a control unit that sets the wireless resources applied in the logical unit in a second wireless access network different from the first wireless access network based on the resource status information.
[0015] One aspect of this disclosure is a wireless communication node comprising: a receiving unit that receives, from other wireless communication nodes included in a first wireless access network, via an interface directly connected to the other wireless communication nodes, resource status information relating to the usage status of wireless resources in at least a logical unit segmented according to required performance or conditions; and a control unit that, based on the resource status information, sets the wireless resources applied in the logical unit in a second wireless access network different from the first wireless access network.
[0016] One aspect of this disclosure is a wireless communication node comprising: a receiving unit that receives, via an interface directly connected to other wireless communication nodes included in a first wireless access network, resource status information relating to the usage status of wireless resources in at least a logical unit segmented according to required performance or conditions, using a learning model; and a control unit that, based on the resource status information, sets the wireless resources applied in the logical unit in a second wireless access network different from the first wireless access network.
[0017] One aspect of this disclosure is a wireless communication node comprising: a receiving unit (scheduling unit 120) that receives state prediction information from other wireless communication nodes included in a first wireless access network, which includes state prediction results of the other wireless communication nodes using a learning model; and a control unit that sets up wireless communication with a terminal in a second wireless access network different from the first wireless access network based on the state prediction information.

[0056] The embodiments are described below based on the accompanying drawings. Furthermore, the same or similar reference numerals are used to denote the same function or structure, and their descriptions are omitted where appropriate.
[0057] (1) Overall general structure of wireless communication system
[0058] Figure 1This is a schematic diagram of the overall structure of the wireless communication system 10 according to this embodiment. In this embodiment, the wireless communication system 10 is a wireless communication system that follows 5G New Radio (NR) and 6G, and includes a 5G radio access network 20 (hereinafter, 5G RAN 20), a 6G radio access network 30 (hereinafter, 6G RAN 30), and a terminal 200 (UserEquipment 200, hereinafter, UE 200).
[0059] Furthermore, the wireless communication system 10 may also include wireless communication systems that follow a protocol known as Long Term Evolution (LTE) or 4G. That is, the wireless communication system 10 may consist of multiple wireless communication systems following different Radio Access Technologies (RATs). Additionally, the wireless communication system 10 may support functions related to the Industrial Internet of Things (IIoT) and Ultra-Reliable and Low-Latency Communications (URLLC).
[0060] 5G RAN 20 and 6G RAN 30 include radio base station 100 (hereinafter, gNB 100). Furthermore, the specific structure of the wireless communication system 10, including the number of gNBs (which may also be eNBs, etc.) and UEs, is not limited to... Figure 1 The example shown.
[0061] Additionally, the gNB 100 can also use the fronthaul (FH) interface defined by the O-RAN (Open Radio Access Network Alliance). The gNB 100 can include an O-DU (O-RAN Distributed Unit) and an O-RU (O-RAN Radio Unit). The gNB100 can function as an NG-RAN node (wireless communication node).
[0062] 5G RAN 20 contains multiple 5G RAN nodes, specifically multiple gNBs (or ng-eNBs), connected to the 5G-compliant core network (CN), namely 5GC 25. Similarly, 6G RAN 30 contains multiple 6G RAN nodes, specifically multiple gNBs, connected to the 6G-compliant core network, namely 6GC 35. In 5GC 25 and 6GC 35, the concept of CUPS (Control and User Plane Separation), which explicitly separates the functions of the user plane and the control plane, can be introduced.
[0063] 5G RAN 20 can connect to OAM / RIC 40 and NF 50 via 5GC 25 or directly from 5G RAN 20. Similarly, 6G RAN 30 can connect to OAM / RIC 40 and NF 50 via 6GC 35 or directly from 6G RAN 30.
[0064] OAM / RIC 40 provides functions related to the operation and maintenance of the wireless communication system 10 (OAM). Additionally, OAM / RIC 40 provides functions related to the control of the 5G RAN 20 (RIC: RAN Intelligent Controller). The specific functions of the RIC are defined by the O-RAN specification (e.g., O-RAN Architecture-Description 6.0). In this embodiment, OAM / RIC 40 can constitute an entity that performs operation and maintenance or control.
[0065] 5GC 25 and 6GC 35 may include logical nodes (network devices) that provide network functions (NFs). Specifically, NF 50 may include an Access and Mobility Management Function (AMF) that provides access and mobility management functions for UE 200, a Session Management Function (SMF) that provides session management functions, and a Location Management Function (LMF) responsible for communication control related to the location information services specified in 5GC 25. Additionally, the AMF and / or SMF may connect to the UDM / UDR (Unified Data Management / User Data Repository). Furthermore, 5G RAN 20, 5GC 25, 6G RAN 30, and 6GC 35 can also be simply referred to as a "network".
[0066] In addition, 5G RAN 20 can also connect to servers managed by a 3GPP service provider or servers managed by a provider other than the 3GPP service provider (3GPP or non-3GPP server).
[0067] The gNB 100 is a NR-compliant radio base station that performs NR-compliant wireless communication with the UE 200. Furthermore, the gNB 100 can consist of a CU (Central Unit) and a DU (Distributed Unit), with the DU located separately from the CU in geographically distinct locations. A CU can connect to one or more DUs. Additionally, gNB 100 units (gNB-CU) can connect to each other via the Xn interface, and CUs and DUs can connect via the F1 interface. The gNB 100 (CU) can connect to NF 50 and other similar devices via the NG interface (also referred to by different names).
[0068] The gNB 100 and UE 200 can support Massive MIMO (Multiple Input Multiple Output) which generates a more directional beam BM by controlling radio signals transmitted from multiple antenna elements, carrier aggregation (CA) which uses multiple component carriers (CC), and dual connectivity (DC) which allows simultaneous communication between the UE and multiple NG-RAN nodes. Additionally, the UE 200 can perform handovers (HO) to different RATs.
[0069] UE 200 can also perform measurement reporting periodically. UE 200 can also perform measurement reporting on an event-by-event basis. Entry conditions for starting measurement reporting and exit conditions for ending measurement reporting can be specified on an event-by-event basis. Furthermore, entry conditions can be interpreted as conditions for determining whether a measurement report is included in the reporting list, and exit conditions can be interpreted as conditions for determining whether a measurement report is excluded from the reporting list.
[0070] In addition, the mobility of UE 200 can be broadly defined as the ease of movement and maneuverability of UE 200. In this embodiment, it can also refer to the minimization of call drop, radio link (including beam) failure, unnecessary handover, ping-pong state, etc.
[0071] UE 200 can also have two independent protocol stacks. Specifically, it can have two protocol stacks consisting of the Physical Layer (PHY), Medium Access Control Layer (MAC), Radio Link Control Layer (RLC), Packet Data Convergence Protocol Layer (PDCP), Radio Resource Control Layer (RRC), and Non-Access Stratum (NAS). Such a protocol stack can also be called a dual stack.
[0072] In the wireless communication system 10, network slicing is supported. In network slicing, the network is divided into service units (slices) based on use cases, business models, etc., so that the performance requirements of each slice are optimized.
[0073] From this perspective, network slicing is a technique that divides a single network (which can be defined as at least one of 5G RAN 20, 5GC 25, 6G RAN30, or 6GC 35) into multiple slices corresponding to different service requirements. Network slicing can also be interpreted as a technique for logically dividing the structure or resources according to each characteristic of various requirements or communication services. Specific examples of network slicing will be described further later.
[0074] In addition, in this embodiment, the channel includes a control channel and a data channel. The control channel includes PDCCH (Physical Downlink Control Channel), PUCCH (Physical Uplink Control Channel), PRACH (Physical Random Access Channel), and PBCH (Physical Broadcast Channel), etc.
[0075] In addition, data channels include PDSCH (Physical Downlink Shared Channel) and PUSCH (Physical Uplink Shared Channel), etc.
[0076] In addition, reference signals include demodulation reference signals (DMRS), sounding reference signals (SRS), phase tracking reference signals (PTRS), and channel state information reference signals (CSI-RS), etc. The signals encompass both the channel and the reference signals. Furthermore, data can refer to data transmitted via a data channel.
[0077] (2) Functional block structure of wireless communication system
[0078] Next, the functional block structure of the wireless communication system 10 will be described. Specifically, the functional block structure of the gNB 100 will be described. Figure 2 This is the function block structure diagram of gNB 100.
[0079] like Figure 2As shown, the gNB 100 includes a wireless communication unit 110, a scheduling unit 120, a slice processing unit 125, an AI / ML model unit 130, and a control unit 140. In this embodiment, the gNB 100 can be configured as a wireless communication node.
[0080] The wireless communication unit 110 transmits downlink signals (DL signals) conforming to NR (Normally Accepted Radio Frequency). Additionally, the wireless communication unit 110 receives uplink signals (UL signals) conforming to NR. The wireless communication unit 110 can use one or more transceiver points (TRPs) to transmit DL signals and receive UL signals. In this embodiment, TRP can also be interpreted as multiple transmit antennas of the DL signal.
[0081] The scheduling unit 120 performs the scheduling of radio resources allocated to the UE 200. In particular, in this embodiment, the scheduling unit 120 is capable of performing dynamic coordination of radio resource allocation for the UE 200 between the 5G RAN 20 and the 6G RAN 30.
[0082] Specifically, the scheduling unit 120 can perform coordination following Multi-RAT spectrum sharing (MRSS). MRSS can also be referred to as Dynamic Spectrum Sharing (DSS) or Dynamic Resource Coordination, etc.
[0083] The scheduling unit 120 can receive state prediction information from other wireless communication nodes (e.g., gNBs) included in the first radio access network (e.g., 5G RAN 20), which contains state prediction results of those other wireless communication nodes using a learning model (AI / ML Model). In this embodiment, the scheduling unit 120 can be configured as a receiving unit for receiving state prediction information.
[0084] Furthermore, a wireless communication node can typically refer to a gNB, but it can also refer to a CU or DU, or an OAM / RIC 40 or NF 50. Additionally, the first radio access network can be either 5G RAN 20 or 6G RAN 30.
[0085] For example, the scheduling unit 120 can receive state prediction information containing predictions of power consumption in the gNB. This power consumption can vary depending on the transmission power of the radio signals (or channels) sent to multiple UEs 200 within the cell.
[0086] The dispatch unit 120 can also receive state prediction information that includes the energy cost of the other wireless communication node. Energy cost can also be interpreted as energy consumption, and as a specific example, it can be the electrical power consumed in the wireless communication node as described above.
[0087] The dispatch unit 120 can also receive state prediction information that includes state prediction results for cell or beam units formed by the other wireless communication nodes. Besides cells or beams, state prediction results for node units or UE units can also be set as objects. Additionally, cell groups can be set as units. Alternatively, state prediction results for frequency bands (band domains) or component carrier units can be set as objects.
[0088] The scheduling unit 120 can also receive state prediction information that includes state prediction results for network slices, i.e., logical units segmented according to required performance or conditions. Specifically, the scheduling unit 120 can receive state prediction information that includes state prediction results for network slice units categorized according to service units such as use cases and business models.
[0089] The scheduling unit 120 can also receive state prediction information that includes the total energy cost related to multiple UEs 200 connected to the other wireless communication node. Specifically, the scheduling unit 120 can also receive state prediction information that includes the total transmit power of the multiple UEs 200.
[0090] The slice processing unit 125 performs processing related to network slicing. As described above, a network slice can be interpreted as a logical unit divided according to at least the required performance or conditions. Furthermore, network slices can be identified by information such as Network Slice Selection Assistance Information (NSSAI).
[0091] The slice processing unit 125 can receive resource status information related to the usage status of radio resources in a specific network slice from other wireless communication nodes (e.g., gNBs) included in the first radio access network (e.g., 5G RAN 20). In this embodiment, the slice processing unit 125 may be configured as a receiving unit for receiving resource status information.
[0092] In addition, the slice processing unit 125 can also receive resource status information related to the usage status of wireless resources in a specific network slice from the other wireless communication nodes included in the first wireless access network, which uses a learning model (AI / ML Model).
[0093] The usage status of radio resources can indicate whether a specific radio resource (e.g., time resource or frequency resource) is used in the RAT, or it can indicate whether it is used or intended to be used. Alternatively, the usage status of radio resources can also indicate whether a specific radio resource is allocated to a synchronization signal block (SSB / PBCH), reference signal, or physical channel.
[0094] In this way, the slicing processing unit 125 can receive resource status information indicating whether radio resources in the first radio access network are in use. Additionally, the slicing processing unit 125 can receive resource status information indicating whether physical layer channels in the first radio access network are in use.
[0095] Furthermore, regarding network slicing, the slice processing unit 125 can also receive resource status information based on bit sequences for each network slice in the first radio access network. Each bit constituting the bit sequence can be associated with a physical resource block (PRB), for example. Alternatively, it can be associated with a pair of PRBs within a subframe, or with a subframe (or a frame, symbol, time slot, etc.).
[0096] The slicing processing unit 125 can also receive the resource status information described above via an interface that is directly connected to the other wireless communication node. This interface could be, for example, an interface that directly connects a 5G DU to a 6G DU. Alternatively, it could be an interface that connects a 5G CU to a 6G DU, or vice versa. Here, "direct connection" can also be interpreted as an interface that connects the other wireless communication nodes, such as the DU, without using an interface that connects the 5G CU to the 6G CU (e.g., Xn).
[0097] In addition, the slice processing unit 125 can also receive resource status information related to the usage status of wireless resources in the network slice from other wireless communication nodes included in the first wireless access network via an interface directly connected to the other wireless communication nodes.
[0098] Specifically, the slice processing unit 125 can receive resource status information representing the capacity of available radio resources for each network slice in the first radio access network. The capacity of available radio resources for each network slice can be, for example, the size of the available PRB in the uplink (UL) and / or downlink (DL), or the size of the available PRB as a specific QoS (e.g., Guaranteed Bitrate (GBR)).
[0099] The slicing processing unit 125 can also receive resource status information of the cell or beam unit formed by the other wireless communication node. As mentioned above, in addition to cells or beams, it can also be node units, etc.
[0100] Alternatively, the slice processing unit 125 can also send a transmission request for resource status information, including the transmission period of resource status information, to the other wireless communication node. In this embodiment, the slice processing unit 125 can be configured as a transmission unit that sends transmission requests for resource status information.
[0101] The slicing processing unit 125 can also receive resource status information related to the usage status of wireless resources in the network slice, which uses a learning model (AI / ML Model), from other wireless communication nodes included in the first wireless access network via an interface directly connected to those other wireless communication nodes. Furthermore, as described above, the directly connected interface could be, for example, an interface that directly connects a 5G DU to a 6G DU.
[0102] The AI / ML model unit 130 performs processing that utilizes a learning model (AI / ML Model). Specifically, the AI / ML model unit 130 performs processing that utilizes the AI / ML model (AI / ML Model) applied in the optimization of mobility and / or handover of the UE 200.
[0103] In particular, in this embodiment, the AI / ML model unit 130 is able to predict the usage status of wireless resources in each network slice within the gNB 100 (also referred to as a wireless communication node or RAN node).
[0104] Furthermore, the AI / ML model unit 130 can predict power consumption and other parameters in the gNB 100. The prediction period can be the very near future (e.g., a few seconds later) or the more distant future (e.g., several hours or 24 hours later). The AI / ML model used can, for example, comply with the requirements of 3GPP TS 28.105. The AI / ML model unit 130 can transmit the future state prediction results of the gNB 100 using the AI / ML model to other wireless communication nodes.
[0105] The control unit 140 controls the functional blocks constituting the gNB 100. Specifically, in this embodiment, the control unit 140 can set the wireless resources used in a network slice of a second wireless access network (e.g., 6G), which is different from the first wireless access network, based on the resource status information received by the slice processing unit 125. Furthermore, in this embodiment, the first wireless access network is primarily described as 5G and the second wireless access network as 6G, but it is also possible to set the first wireless access network to 6G and the second wireless access network to 5G.
[0106] Furthermore, the control unit 140 can configure wireless communication with the UE 200 in the second radio access network based on the state prediction information received by the scheduling unit 120. The wireless communication configuration can include various settings at the PHY, MAC, RLC, PDCP, and RRC layers.
[0107] (3) Operation of wireless communication system
[0108] Next, the operation of the wireless communication system 10 will be explained. Specifically, the operation related to MRSS between 5G and 6G will be explained. In particular, the operation related to network slicing and MRSS as the target, as well as the operation related to MRSS taking into account the power consumption in the wireless communication nodes, will be explained.
[0109] (3.1) Prerequisites and topics
[0110] Figure 3 This is a schematic diagram illustrating resource coordination between 5G and 6G. Now, let's envision the rollout of 6G around 2030. During the migration phase, we envision either deploying 6G as a secondary node (SN) in a dual-connectivity (DC) relationship with 5G, or deploying 6G independently.
[0111] Especially when 6G is deployed independently, from the perspective of ensuring coverage areas, it is desirable to prioritize the allocation of low-frequency bands such as the so-called Platinum Band to 6G. In this migration phase from 5G to 6G, MRSS, a technology that dynamically coordinates and uses radio resources between the 5G RAN and the 6G RAN, is required.
[0112] Figure 4 An example of a network slice structure is shown. For example... Figure 4 As shown, the network can be segmented into service units (slices) based on use cases, business models, etc. Figure 4The diagram illustrates examples of network slices divided into eMBB (enhanced Mobile Broadband), URLLC, and other network slices. Radio resources within the RAN scheduler can be allocated to specific network slices.
[0113] Figure 5 Examples of DU options that can be applied in this embodiment are shown. In this embodiment, Figure 5 All of the DU options shown can be applied.
[0114] (3.2) Example 1 of the action
[0115] In this action example, resource sharing is performed for each network slice when MRSS is applied.
[0116] Specifically, information (which may consist of bit strings, etc.) related to the use of radio resources can be notified from the 5G RAN to the 6G RAN on a per network slice (per NSSAI) basis.
[0117] This information can indicate, for example, whether the radio resource is intended to be used for transmission or whether it is not intended to be used for transmission. Specifically, it can indicate whether the radio resource is allocated to a 5G SSB, CSI-RS, DM-RS, SRS, TRS (Tracking-Reference Signal), PRS (Positioning Reference Signal), PDCCH, PDSCH, PUCCH, PUSCH, or an equivalent physical channel.
[0118] Similarly, information (which may consist of bit strings, etc.) related to the use of radio resources can be notified from the 6G RAN to the 5G RAN on a per network slice (per NSSAI) basis.
[0119] Additionally, the following information can also be communicated. Specifically, the 5G RAN can notify the 6G RAN of the dynamic radio resource usage status of RE (Resource Element) or RB units. Furthermore, the 5G RAN can also notify the 6G RAN of the same information.
[0120] DL's radio resources and UL's radio resources can also be coordinated separately. In addition, coordination can be carried out on a per-frequency (or per-band) basis, or frequency information can be represented (e.g., ARFCN (Absolute Radio-Frequency Channel Number)).
[0121] Coordination can also be performed on a per-cell or per-beam basis. In this case, the cell ID, beam ID, SSB, or CSI-RS can be set as the reference. This allows for finer-grained coordination.
[0122] Multiple cells or beams can also be grouped into one group and coordinated as a single entity. In this case, the ID of the cell group, spectrum sharing group, or beam group can also be displayed.
[0123] The unit for notifying radio resource usage status can be a PRB pair or a PRB. In the time domain, it can be a time slot or a subframe. In the frequency domain, it can be 12 subcarriers (e.g., 12...). 15 (SCS) = 180 kHz.
[0124] The wireless communication node that initiates coordination can be either the 5G RAN side or the 6G RAN side. SSB pattern or CSI-RS pattern can be used for coordination. Radio resources allocated with reference signals (RS) in the 6G RAN, or this pattern, can be communicated to the 5G RAN. This allows for finer-grained coordination.
[0125] Bandwidth, SCS, cyclic prefix (CP), DL-UL transmission period, symbol allocation within a time slot (number of DL / UL symbols), or permutation representing the positions of UL / DL symbols within a time slot (e.g., DFU, UFD, F=Flexible) can be coordinated.
[0126] Alternatively, AI / ML models can be used to predict the future radio resource usage / patterns of each wireless communication node, and a bit string representing the prediction result can be sent as notification. 5G RAN and 6G RAN allocate radio resources based on predictions from AI / ML models, thereby reducing the frequency of dynamic radio resource coordination. Furthermore, in the case of semi-static coordination, the coordination period can be predetermined and communicated in advance.
[0127] Radio resources can also be grouped / patterned in every N (e.g., 40, 80, 120, etc.) RE / PRB / PRB pairs / subframes / slots / symbols, and coordination can be carried out based on the grouped / patterned objects.
[0128] Multiple frequencies or carriers can also be combined and coordinated based on that combination. For example, coordination can also be carried out by combining each band domain of CA / DC.
[0129] The validity period can also be set in the aforementioned wireless resource modes. This validity period can be managed using a timer (or a new one). In semi-static coordination, the period of the wireless resource exchange mode can be set as the validity period.
[0130] This mode can be coordinated between the 5G RAN and the 6G RAN. For example, a specific mode can be proposed from the 5G RAN to the 6G RAN, and the 6G RAN will respond with an affirmative acknowledgment (Ack) to that mode. The mode can also be determined by the master node (MN). The slave node (SN) can follow the mode determined by the MN.
[0131] Alternatively, the SN can be considered valid for the current mode until a new mode is notified from the MN. Or, if the validity period has expired, the mode can be terminated, and mode-related coordination can be re-executed. Therefore, coordinating radio resources in RE / PRB / PRB units can become more efficient.
[0132] Figure 6 This example shows a bit string structure representing the usage status of slice-based wireless resources involved in Action Example 1. Figure 7 This example shows a bit string structure representing the usage status of slice-based wireless resources involved in Action Example 1.
[0133] like Figure 6 As shown, the bit string can be set for each network slice. Each bit can indicate whether a PRB pair or a PRB, etc., is used for transmission in that slice. Figure 6 In this context, "0" indicates that it is not used for transmission, and "1" indicates that it is used for transmission, but the reverse is also possible. Additionally, as... Figure 7 As shown, bit strings can also represent usage status using both the time domain and the frequency domain as objects.
[0134] Figure 8 This illustrates a coordination example (DU-to-DU) of the radio resources involved in Action Example 1. For example... Figure 8As shown, information related to the use of radio resources for each network slice can be exchanged between the 5G DU and the 6G DU. New interfaces can be configured between the 5G DU and the 6G DU.

Figure 11 As shown, information regarding the use of radio resources for each network slice can be exchanged between the 5G DU and 6G DU via the CU. Furthermore, the CU here can be either a 5G-side or a 6G-side CU. Alternatively, it can be a generic CU capable of supporting any RAN.

Figure 12 As shown, it can be accessed via OAM / RIC 40 (see reference). Figure 1 Information related to the use of wireless resources for each network slice is exchanged between DUs.
[0139] (3.3) Example 2 of the action
[0140] In this action example, an AI / ML model is used to predict the future usage status of radio resources for each network slice within a RAN node. Specifically, MRSS is applied, and the future usage status of radio resources predicted by the AI / ML model is exchanged between wireless communication nodes.
[0141] Wireless communication nodes can use AI / ML models to predict the future availability and / or usage patterns of wireless resources on a per-network-slice basis. The wireless communication node can then send a bit string representing the prediction result to other wireless communication nodes.
[0142] For example, 5G RAN and 6G RAN can allocate radio resources based on predictions using AI / ML models. This reduces the frequency of dynamic radio resource coordination.
[0143] Similar to Action Example 1, information about radio resource usage predicted using an AI / ML model can also indicate whether the radio resource is intended to be used for transmission or not. Specifically, it can indicate whether the radio resource is allocated to a 5G SSB, CSI-RS, DM-RS, SRS, TRS (Tracking-Reference Signal), PRS (Positioning Reference Signal), PDCCH, PDSCH, PUCCH, PUSCH, or an equivalent physical channel.
[0144] Information (which may consist of bit strings, etc.) related to radio resource usage can be notified from the 5G RAN to the 6G RAN on a per-network-slice (per-NSSAI) basis. Similarly, information (which may consist of bit strings, etc.) related to radio resource usage can be notified from the 6G RAN to the 5G RAN on a per-network-slice (per-NSSAI) basis.
[0145] Figure 13 This illustrates a coordination example (DU-to-DU) of the radio resources involved in Action Example 2. For example... Figure 13 As shown, information regarding radio resource usage for each network slice, predicted using AI / ML models, can be exchanged between 5G DUs and 6G DUs. New interfaces can be configured between 5G DUs and 6G DUs. Furthermore, network slices can be replaced with NSSAI or network slice groups.

Figure 16 As shown, information regarding radio resource usage for each network slice, predicted using AI / ML models, can be exchanged between 5G DUs and 6G DUs via the CU. Furthermore, the CU here can be either a 5G-side or a 6G-side CU, or a generic CU capable of supporting any RAN.
[0149] Figure 17 This illustrates a coordination example of radio resources involved in Action Example 2 (via OAM / RIC). For example... Figure 17 As shown, it can be accessed via OAM / RIC 40 (see reference). Figure 1 Information about the use of wireless resources for each network slice is exchanged between DUs using AI / ML models to predict the usage of each network slice.
[0150] (3.4) Action Example 3
[0151] In this example, when MRSS is applied, resource sharing for each network slice is performed via an interface that directly connects the 5G-side wireless communication node (RAN node) to the 6G-side wireless communication node (RAN node). This enables direct dynamic load balancing and / or bandwidth distribution among the RAN nodes.
[0152] Furthermore, this example assumes resource sharing between 5G RAN nodes and 6G RAN nodes, but it could also be between 6G RAN nodes. Additionally, the number of UEs (users) utilizing this frequency band can also be considered. Moreover, such features can be applied to other examples.
[0153] Information regarding radio resource usage can be communicated from the 5G RAN to the 6G RAN on a per-network-slice basis via an interface that directly connects the 5G RAN node and the 6G RAN node (referred to herein as the new interface). For example, the available capacity value of radio resources in a network slice can be communicated (Downlink / Uplink), DL / UL GBR PRB usage per slice, and DL / UL non-GBR PRB usage per slice).
[0154] Similarly, information related to radio resource usage can be communicated from the 6G RAN to the 5G RAN on a per-network-slice basis via this new interface.
[0155] This information can also be in cell or beam unit format. Additionally, this information can be sent periodically to other RAN nodes in response to transmission requests from them.
[0156] This new interface can also be used to notify the 6G RAN of the number of active UEs in each frequency band (e.g., frequency band = X, number of active UEs: 30; frequency band = Y, number of active UEs: 10). The same information can also be communicated from the 6G RAN to the 5G RAN. This information may also include the UE type: (XR (Cross Reality) UE, normal UE, RedCap UE (Reduced UE Capability), etc.).
[0157] This new interface can also be used to notify the 6G RAN of the number of active UEs for each network slice (e.g., slice = A, number of active UEs: 30; slice = B, number of active UEs: 10). The same information can also be notified from the 6G RAN to the 5G RAN. This information may also include the UE type: (XR UE, normal UE, RedCap UE, etc.).
[0158] This new interface can also be used to notify the 6G RAN of the number of RRS connections for each network slice (e.g., slice=A, RRC connections: 30; slice=B, RRC connections: 10), and the same information can be notified from the 6G RAN to the 5G RAN. This information may also include the UE type (e.g., XR UE, normal UE, RedCap UE, etc.).
[0159] This new interface can also be used to notify the 6G RAN of the number of active UEs for each SSB or SSB area (e.g., SSB index = 1, number of active UEs: 30; SSB index = 2, number of active UEs: 10). The same information can also be notified from the 6G RAN to the 5G RAN. This information may also include the UE type: (XR UE, normal UE, RedCap UE, etc.).
[0160] This new interface also allows for notification of radio resource usage for each QoS or logical channel or data radio bearer (DRB) from the 5G RAN to the 6G RAN. Similarly, the same information can be communicated from the 6G RAN to the 5G RAN.
[0161] Furthermore, in this example, the information is based on the exchange between DUs, but it can also be exchanged between CUs.
[0162] Alternatively, this new interface can also be used to notify the 6G RAN of load status information from the 5G RAN, and vice versa. The load status can be at least one of the following.
[0163] • Cell ID or Beam ID
[0164] • Radio resource status
[0165] • DL / UL GBR PRB usage
[0166] • DL / UL non-GBR PRB usage
[0167] •DL / UL Total PRB

[0173] • DL / UL scheduling PDCCH CCE usage
[0174] MIMO PRB usage information
[0175] • DL / UL GBR PRB usage for MIMO
[0176] • DL / UL non-GBR PRB usage for MIMO
[0177] • Total DL / UL PRB usage for MIMO

[0179] • The capacity offered by DL TNL (maximum capacity offered by the transport portion of the cell in kbps).
[0180] • DLTNL available capacity (Available capacity over the transport portion serving the cell, expressed as a percentage).
[0181] • UL TNL offered capacity (Maximum capacity offered by the transport portion of the cell in kbps)
[0182] • UL TNL available capacity (Available capacity over the transport portion serving the cell in percentage. Value 100 corresponds to the offered capacity)
[0183] • Composite Available capacity group (overall available resource level per cell and per SSB area in the cell in Downlink, Uplink and Supplementary Uplink.)
[0184] • Slice available capacity
[0185] • Number of active UEs
[0186] • RRC connections
[0187] • Number of RRC connections
[0188] • Available RRC connection capacity value

Figure 26 As shown, it can be accessed via OAM / RIC 40 (see reference). Figure 1They exchanged the aforementioned information related to the usage of wireless resources.
[0199] (3.5) Example 4 of the action
[0200] In this action example, the future usage of radio resources is predicted for each network slice within a RAN node by using an AI / ML model.
[0201] With an interface that directly connects 5G RAN nodes and 6G RAN nodes, the radio resource status and load status of each network slice, predicted using AI / ML models, can be exchanged between these nodes. This enables appropriate load balancing and bandwidth distribution among nodes.
[0202] Information regarding radio resource usage per network slice, predicted using an AI / ML model, can be communicated from the 5G RAN to the 6G RAN via an interface that directly connects the 5G RAN node and the 6G RAN node (referred to herein as the new interface). Similar to Action Example 3, for example, the available radio resource capacity in the network slice can be communicated (Available Capacity Value Downlink / Uplink, DL / UL GBR PRB usage per slice, DL / UL non-GBR PRB usage per slice).
[0203] Similarly, information related to radio resource usage can be communicated from the 6G RAN to the 5G RAN on a per-network-slice basis via this new interface.
[0204] This information can also be in cell or beam unit format. Additionally, this information can be sent periodically to other RAN nodes in response to transmission requests from them.
[0205] Alternatively, this new interface can also be used to notify the 6G RAN of load status information from the 5G RAN, and vice versa. The load status can be at least one of the following.
[0206] • Cell ID or Beam ID
[0207] • The predicted number of active UEs
[0208] • Predicted RRC connections
[0209] • Predicted Number of RRC Connections
[0210] • Predicted Available RRC ConnectionCapacity Value
[0211] In addition, similar to action example 3, the number of active users in each frequency band, the number of active users in each network slice, the number of RRS connections in each network slice, and the number of active users in each SSB or SSB area can be notified.

Figure 27 As shown, information about the use of radio resources for each network slice, predicted by AI / ML models, can be exchanged between 6G DUs and 5G DUs, or between 6G DUs, via the interface of the directly connected DU.

Figure 32 As shown, it can be accessed via OAM / RIC 40 (see reference). Figure 1 They exchanged the aforementioned information related to the usage of wireless resources.
[0218] (3.6) Action Example 5
[0219] In this action example, an AI / ML model is used to predict future power consumption (energy cost) within a RAN node.
[0220] With interfaces that directly connect 5G RAN nodes and 6G RAN nodes, information representing future power consumption predicted by AI / ML models can be exchanged between these nodes. This enables appropriate load balancing between nodes, potentially leading to energy savings for the entire network.
[0221] Furthermore, in this example, the information is based on the exchange between DUs, but it can also be exchanged between CUs.
[0222] Specifically, information related to energy costs, predicted or measured using AI / ML models, can be exchanged between 5G RAN and 6G RAN via an interface that directly connects 5G RAN nodes and 6G RAN nodes (referred to here as the new interface).
[0223] Similarly, this new interface can be used to notify the 5G RAN of energy cost-related information from the 6G RAN. The energy cost-related information can be at least one of the following.
[0224] • Predicted per beam energy cost (energy consumption)
[0225] • Predicted per cell energy cost (energy consumption)
[0226] • Predicted per cell group energy cost (energy consumption)
[0227] • Predicted per node energy cost (energy consumption)
[0228] • Predicted energy cost (energy consumption) per slice
[0229] • Predicted per UE energy cost (energy consumption)
[0230] • Predicted energy cost (energy consumption) per group of UEs
[0231] • Predicted energy cost (energy consumption) per frequencyband / carrier component
[0232] • Measured per beam energy cost (energy consumption)
[0233] • Measured per cell energy cost (energy consumption)
[0234] • Measured per cell group energy cost (energy consumption)
[0235] • Measured per node energy cost (energy consumption)
[0236] • Measured per slice energy cost (energy consumption)
[0237] • Measured per frequencyband / carrier components energy cost (energy consumption)
[0238] • Measured per UE energy cost (energy consumption)
[0239] • Measured per group of UEs energy cost (energy consumption)
[0240] Figure 33 This illustrates a timing example (between 6G DU and 5G / 6G DU) related to the sharing of information representing energy costs involved in Action Example 5. For example... Figure 33 As shown, information related to energy costs, predicted or measured using AI / ML models, can be exchanged between 6G DUs and 5G DUs, or between 6G DUs, via the interface of the directly connected DU.
[0241] Figure 34 This illustrates a timing example (between 6G DU and 5G / 6G DU) related to the sharing of information representing energy costs involved in Action Example 5. For example... Figure 34 As shown, information related to energy costs for each frequency band can be exchanged via this interface that directly connects to the DU.
[0242] Figure 35 This illustrates a timing example (between 6G CU and 5G / 6G CU) related to the sharing of information representing energy costs involved in Action Example 5. For example... Figure 35As shown, information related to energy costs for each frequency band can be exchanged via this interface that is directly connected to the CU.
[0243] Figure 36 This illustrates a timing example (via OAM / RIC) related to the sharing of information representing energy costs involved in Action Example 5. For example... Figure 36 As shown, it can be accessed via OAM / RIC 40 (see reference). Figure 1 They exchanged the aforementioned information related to energy costs.
[0244] Based on the action examples described above, when MRSS is applied, the following information is shared between the 5G RAN node and the 6G RAN node.
[0245] • The usage of radio resources for each network slice (including via the interface that directly connects 5G RAN nodes and 6G RAN nodes).
[0246] • Radio resource usage predicted for each network slice using AI / ML models
[0247] • The usage of radio resources for each network slice (including via the interface that directly connects 5G RAN nodes and 6G RAN nodes).
[0248] • Energy cost-related information predicted or measured using AI / ML models (including interfaces that directly connect 5G RAN nodes to 6G RAN nodes).
[0249] Therefore, it enables rapid and accurate sharing of information related to the usage status of radio resources between 5G and 6G RAN nodes. This, in turn, allows for more efficient sharing of 5G and 6G radio resources.

[0266] The communication device 1004 is hardware (transceiver) used for communication between computers via at least one of a wired network and a wireless network. For example, it may also be called a network device, network controller, network card, communication module, etc.
[0267] The communication device 1004 may also be configured to include a high-frequency switch, a duplexer, a filter, a frequency synthesizer, etc., to realize at least one of frequency division duplex (FDD) and time division duplex (TDD).
[0268] Input device 1005 is an input device that accepts input from external sources (e.g., keyboard, mouse, microphone, switch, button, sensor, etc.). Output device 1006 is an output device that performs output to external sources (e.g., display, speaker, LED, etc.). Furthermore, input device 1005 and output device 1006 can also be integrated (e.g., a touch panel).
[0269] Furthermore, the processor 1001, memory 1002, and other devices are connected via a bus 1007 for communicating information. The bus 1007 can be configured using a single bus or different buses can be used between each device.
[0270] Furthermore, the device can be configured to include hardware such as a microprocessor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a programmable logic device (PLD), and a field-programmable gate array (FPGA), which can be used to implement some or all of the functional blocks. For example, the processor 1001 can also be implemented using at least one of these hardware components.
[0271] Furthermore, the notification of information is not limited to the forms / implementations described in this disclosure, and other methods may also be used. For example, information notification may be implemented through physical layer signaling (e.g., Downlink Control Information (DCI), Uplink Control Information (UCI), higher layer signaling (e.g., RRC signaling, Medium Access Control (MAC) signaling, broadcast information (Master Information Block (MIB), System Information Block (SIB))), other signals, or combinations thereof. Additionally, RRC signaling may also be referred to as an RRC message, for example, an RRC Connection Setup message, an RRC Connection Reconfiguration message, etc.

Alternatively, multiple systems may be combined (e.g., a combination of at least one of LTE and LTE-A with 5G, etc.) for application.
[0273] The processing procedures, timing, and flow of the various forms / implementations described in this disclosure may be changed in order, provided there is no contradiction. For example, the elements of various steps are indicated using an illustrative order in the methods described in this disclosure, but are not limited to the specific order indicated.
[0274] In this disclosure, certain actions performed by the base station are sometimes also performed by its upper node, depending on the circumstances. In a network consisting of one or more network nodes having a base station, it is obvious that various actions performed to communicate with a terminal can be performed by at least one of the base station and other network nodes besides the base station (e.g., considering an MME or S-GW, but not limited to these). The above illustration depicts a case where there is only one other network node besides the base station, but it can also be a combination of multiple other network nodes (e.g., an MME and an S-GW).
[0275] It can output information and signals (information, etc.) from a higher (or lower) level to a lower (or higher) level. It can also input and output through multiple network nodes.
[0276] Input and output information can be stored in a specific location (e.g., memory) or managed using a management table. Input and output information can be overwritten, updated, or appended. Output information can also be deleted. Input information can also be sent to other devices.
[0277] The determination can be made by the value represented by 1 bit (0 or 1), by a Boolean value (Boolean: true or false), or by comparing numerical values (e.g., comparing with a predetermined value).
[0278] The various forms / implementations described in this disclosure can be used individually or in combination, and can be switched depending on the execution. Furthermore, the notification of predetermined information (e.g., a "It is X" notification) is not limited to being explicit, but can also be implicit (e.g., not notifying the predetermined information).
[0279] Software, whether called software, firmware, middleware, microcode, hardware description language, or by other names, should be broadly interpreted as referring to commands, command sets, code, code segments, program code, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, procedures, functions, etc.
[0280] In addition, software, commands, information, etc., can be sent and received via a transmission medium. For example, when software is sent from a webpage, server, or other remote source using at least one of wired technologies (coaxial cable, fiber optic cable, twisted pair, Digital Subscriber Line (DSL) etc.) and wireless technologies (infrared, microwave, etc.), at least one of these wired and wireless technologies is included within the definition of a transmission medium.
[0281] The information, signals, etc., described in this disclosure can also be represented using any of a variety of different technologies. For example, the data, commands, instructions, information, signals, bits, symbols, chips, etc., that may be involved in the above description as a whole can be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or photons, or any combination of these.
[0282] Furthermore, the terms used in this disclosure and those necessary for understanding this disclosure may be replaced with terms that have the same or similar meanings. For example, at least one of the channel and symbol may also be a signal (signaling). Additionally, a signal may also be a message. Furthermore, a component carrier (CC) may also be referred to as a carrier frequency, cell, frequency carrier, etc.
[0283] The terms “system” and “network” as used in this disclosure are used interchangeably.
[0284] Furthermore, the information, parameters, etc., described in this disclosure can be represented using absolute values, relative values to predetermined values, or other corresponding information. For example, wireless resources can be indicated using indexes.
[0285] The names used for the above parameters are non-limiting in any respect. Furthermore, the formulas, etc., using these parameters may sometimes differ from those explicitly disclosed in this disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by any appropriate name, and therefore the various names assigned to these channels and information elements are non-limiting in any respect.
[0286] In this disclosure, the terms "Base Station (BS)," "wireless base station," "fixed station," "NodeB," "eNodeB (eNB)," "gNodeB (gNB)," "access point," "transmission point," "reception point," "transmission / reception point," "cell," "sector," "cell group," "carrier," and "component carrier" are used interchangeably. Sometimes, terms such as macro cell, small cell, femtocell, and picocell are also used to refer to base stations.
[0287] A base station can accommodate one or more (e.g., three) cells (also called sectors). When a base station accommodates multiple cells, the overall coverage area of the base station can be divided into multiple smaller areas, and each smaller area can also provide communication services through the base station subsystem (e.g., a small indoor base station (Remote Radio Head: RRH)).
[0288] Terms such as “cell” or “sector” refer to a portion or the entire coverage area of at least one of the base stations and base station subsystems that provide communication services within that coverage area.
[0289] In this disclosure, the base station sending information to the terminal can also be replaced by the base station instructing the terminal on information-based control / actions.
[0290] In this disclosure, the terms "Mobile Station (MS)," "user terminal," "User Equipment (UE)," and "terminal" are used interchangeably.
[0291] For mobile stations, those skilled in the art sometimes also use the following terms: subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handheld device, user agent, mobile client, client, or some other appropriate terms.
[0292] At least one of the base station and mobile station can also be referred to as a transmitting device, receiving device, communication device, etc. Furthermore, at least one of the base station and mobile station can also be a device mounted on a mobile body, the mobile body itself, etc. The mobile body refers to a movable object with an arbitrary speed of movement. It also includes situations where the mobile body is stationary. Examples of mobile bodies include, but are not limited to, vehicles, transport vehicles, automobiles, motorcycles, bicycles, connected cars, excavators, bulldozers, wheel loaders, dump trucks, forklifts, trains, buses, rear cars, rickshaws, ships (ships and other watercraft), airplanes, rockets, artificial satellites, Drone (registered trademark), multi-rotor helicopters, quadcopter helicopters, balloons, and objects mounted on them. Additionally, the mobile body can also be a mobile body that moves autonomously based on operating commands. It can be a means of transportation (e.g., car, airplane), a mobile body that moves unmanned (e.g., drone, autonomous vehicle), or a robot (humanized or unmanned). Furthermore, at least one of the base station and mobile station also includes devices that do not necessarily move during communication operations. For example, at least one of the base station and the mobile station can be an IoT (Internet of Things) device such as a sensor.
[0293] Furthermore, the base station in this disclosure can also be replaced by a mobile station (user terminal, hereinafter the same). For example, various forms / implementations of this disclosure can also be applied to structures that replace communication between the base station and the mobile station with communication between multiple mobile stations (e.g., also referred to as D2D (Device-to-Device), V2X (Vehicle-to-Everything), etc.). In this case, the structure can also be configured such that the mobile station has the functions of the base station. In addition, terms such as "uplink" and "downlink" can also be replaced with terms corresponding to communication between terminals (e.g., "side"). For example, uplink channel, downlink channel, etc. can also be replaced with side channel (or side link).
[0294] Similarly, the mobile station in this disclosure can be replaced by a base station. In this case, the base station can also be configured to have the functions of a mobile station.
[0295] A wireless frame can consist of one or more frames in the time domain. Each frame in the time domain is called a subframe. A subframe can also consist of one or more time slots in the time domain. A subframe can be a fixed duration (e.g., 1 ms) independent of the parameter set (numerology).
[0296] A parameter set can be communication parameters applied to at least one of the transmission and reception of a signal or channel. For example, a parameter set can represent at least one of the following: Subcarrier Spacing (SCS), bandwidth, symbol length, cyclic prefix length, Transmission Time Interval (TTI), number of symbols per TTI, radio frame structure, specific filtering processing performed by the transceiver in the frequency domain, and specific windowing processing performed by the transceiver in the time domain.
[0297] In the time domain, a time slot can be composed of one or more symbols (OFDM (Orthogonal Frequency Division Multiplexing) symbols, SC-FDMA (Single Carrier Frequency Division Multiple Access) symbols, etc.). A time slot can be a time unit based on a set of parameters.
[0298] A time slot can contain multiple mini-time slots. Each mini-time slot can consist of one or more symbols in the time domain. Additionally, a mini-time slot can also be called a sub-time slot. A mini-time slot can consist of fewer symbols than a time slot. PDSCH (or PUSCH) transmitted in time units larger than mini-time slots can be called PDSCH (or PUSCH) mapping type (type) A. PDSCH (or PUSCH) transmitted using mini-time slots can be called PDSCH (or PUSCH) mapping type (type) B.
[0299] Radio frames, subframes, time slots, mini-time slots, and symbols all represent time units for transmitting signals. Radio frames, subframes, time slots, mini-time slots, and symbols can also be referred to by their respective alternative names.
[0300] For example, a single subframe can be called a Transmission Time Interval (TTI), multiple consecutive subframes can also be called a TTI, and a single time slot or a single mini-time slot can also be called a TTI. In other words, at least one of a subframe or TTI can be a subframe (1ms) in existing LTE, a period shorter than 1ms (e.g., 1-13 symbols), or a period longer than 1ms. Furthermore, the unit representing TTI can also be called a time slot, mini-time slot, etc., instead of a subframe.
[0301] Here, TTI refers, for example, to the smallest unit of time for scheduling in wireless communication. For instance, in an LTE system, the base station schedules the allocation of radio resources (bandwidth, transmit power, etc., available to each user terminal) in units of TTI. However, the definition of TTI is not limited to this.
[0302] The Time Interval (TTI) can be a unit of time for transmitting channel-coded data packets (transmission blocks), code blocks, codewords, etc., or it can be a processing unit such as scheduling or link adaptation. Furthermore, when a TTI is given, the actual time interval (e.g., the number of symbols) that the transmission block, code block, codeword, etc., are mapped to can be shorter than that TTI.
[0303] Furthermore, when one time slot or one mini time slot is referred to as a TTI, more than one TTI (i.e., more than one time slot or more than one mini time slot) can become the minimum time unit for scheduling. In addition, the number of time slots (mini time slots) constituting the minimum time unit for scheduling can also be controlled.
[0304] A TTI with a duration of 1ms can also be called a normal TTI (TTI in LTE Rel.8-12), a long TTI, a normal subframe, a long subframe, or a time slot. A TTI shorter than a normal TTI can also be called a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a mini time slot, a sub-time slot, or a time slot.
[0305] Furthermore, for long TTIs (e.g., normal TTIs, subframes, etc.), they can be replaced with TTIs with a duration of more than 1ms. For short TTIs (e.g., shortened TTIs, etc.), they can be replaced with TTIs with a duration of less than long TTIs but more than 1ms.
[0306] A resource block (RB) is a unit of resource allocation in both the time and frequency domains. In the frequency domain, it can contain one or more consecutive subcarriers. The number of subcarriers contained in an RB can be the same regardless of the parameter set, for example, it can be 12. The number of subcarriers contained in an RB can also be determined based on the parameter set.
[0307] In addition, the time domain of an RB can contain one or more symbols, which can be a time slot, a mini time slot, a subframe, or a TTI in length. A TTI, a subframe, etc., can each be composed of one or more resource blocks.
[0308] In addition, one or more RBs can also be called Physical Resource Block (PRB), Sub-Carrier Group (SCG), Resource Element Group (REG), PRB pair, RB pair, etc.
[0309] In addition, a resource block can consist of one or more resource elements (REs). For example, one RE can be a radio resource area consisting of one subcarrier and one symbol.
[0310] The Bandwidth Part (BWP) (also known as partial bandwidth, etc.) can represent a subset of contiguous common resource blocks (RBs) used for a certain parameter set in a given carrier. Here, common RBs can be determined by indexing RBs based on a common reference point of that carrier. PRBs can be defined and numbered within a BWP.
[0311] A BWP can include a UL BWP and a DL BWP. One or more BWPs can be set for a UE within a single carrier.
[0312] At least one of the configured BWPs can be active, and the UE may not intend to transmit or receive predetermined signals / channels outside of the active BWP. Furthermore, the terms "cell," "carrier," etc., used in this disclosure can be replaced with "BWP."
[0313] The structures of radio frames, subframes, time slots, mini-time slots, and symbols described above are merely illustrative. For example, the number of subframes contained in a radio frame, the number of time slots in each subframe or radio frame, the number of mini-time slots contained within a time slot, the number of symbols and RBs contained in a time slot or mini-time slot, the number of subcarriers contained in an RB, the number of symbols in a TTI, the symbol length, the cyclic prefix (CP) length, etc., can be varied in many ways.
[0314] The terms “connected,” “coupled,” or any variations thereof are intended to indicate any direct or indirect connection or combination between two or more elements, including cases where there is one or more intermediate elements between the two elements that are “connected” or “coupled.” The combination or connection between elements can be physical, logical, or a combination of these. For example, “access” can be used instead of “connected.” In the context of this disclosure, it can be understood that two elements are “connected” or “coupled” to each other using at least one of one or more wires, cables, and printed electrical connections, and, as some non-limiting and non-inclusive examples, they are “connected” or “coupled” to each other using electromagnetic energy with wavelengths in the wireless frequency domain, microwave region, and light (both visible and invisible) region.
[0315] The reference signal can be simply called the Reference Signal (RS), or, depending on the standard applied, the pilot.
[0316] As used in this disclosure, the word "based on" does not mean "based on only" unless otherwise expressly stated. In other words, the word "based on" means both "based on only" and "based on at least".
[0317] Alternatively, the "unit" in the structure of the above devices can be replaced with "section", "circuit", "equipment", etc.
[0318] Any reference to elements using designations such as "first," "second," etc., as used in this disclosure does not necessarily limit the number or order of these elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Therefore, references to "first" and "second" do not imply that only two elements can be used there, or that in some form the first element must precede the second element.
[0319] When the terms "include," "including," and their variations are used in this disclosure, these terms, like the term "comprising," imply inclusion. Furthermore, the term "or" as used in this disclosure does not refer to XOR.
[0320] In this disclosure, for example, in cases where articles are added through translation, such as in English (e.g., a, an, and the), this disclosure may also include cases where the noun following these articles is in a plural form.
[0321] As used in this disclosure, terms such as "determining" and "determining" sometimes encompass a variety of actions. For example, "determining" or "determining" may include actions such as judging, calculating, computing, processing, deriving, investigating, searching (e.g., searching in a table, database, or other data structure), and ascertaining, which are considered as actions of "determining" or "determining." Furthermore, "determining" or "determining" may include actions such as receiving (e.g., receiving information), transmitting (e.g., sending information), inputting, outputting, and accessing (e.g., accessing data in memory), which are considered as actions of "determining" or "determining." Additionally, "determining" or "determining" may include actions such as resolving, selecting, choosing, establishing, and comparing, which are considered as actions of "determining" or "determining." In other words, "judgment" and "decision" can include matters that are considered as having been "judged" or "decided". In addition, "judgment (decision)" can also be replaced by "assuming", "expecting", "considering", etc.
[0322] In this disclosure, the phrase "A and B are different" can mean "A and B are not the same." Furthermore, this phrase can also mean "A and B are each different from C." Terms such as "separate" and "combined" can also be interpreted in the same way as "different."
[0323] Figure 38 An example of the structure of vehicle 2001 is shown. For example... Figure 38 As shown, the vehicle 2001 includes a drive unit 2002, a steering unit 2003, an accelerator pedal 2004, a brake pedal 2005, a gear shift lever 2006, left and right front wheels 2007, left and right rear wheels 2008, an axle 2009, an electronic control unit 2010, various sensors 2021 to 2029, an information service unit 2012, and a communication module 2013.

The Information Service Unit 2012 uses information obtained from external devices via a communication module 2013, etc., to provide various multimedia information and multimedia services to the occupants of vehicle 1.
[0329] The Information Services Department 2012 may include input devices that accept input from external sources (e.g., keyboard, mouse, microphone, switch, button, sensor, touch panel, etc.) and output devices that implement output to external sources (e.g., monitor, speaker, LED light, touch panel, etc.).

Furthermore, the Driver Assistance System 2030 transmits and receives various information via the communication module 2013 to achieve driver assistance or autonomous driving functions.
[0331] The communication module 2013 can communicate with the microprocessor 2031 and the components of the vehicle 1 via the communication port. For example, the communication module 2013 can send and receive data with the drive unit 2002, steering unit 2003, accelerator pedal 2004, brake pedal 2005, gear shift lever 2006, left and right front wheels 2007, left and right rear wheels 2008, axle 2009, microprocessor 2031 in the electronic control unit 2010, memory (ROM, RAM) 2032, and sensors 2021 to 2028 in the vehicle 2001 via the communication port 2033.
[0332] The communication module 2013, controlled by the microprocessor 2031 of the electronic control unit 2010, is a communication device capable of communicating with external devices. For example, it can transmit and receive various types of information with external devices via wireless communication. The communication module 2013 can be located inside or outside the electronic control unit 2010. External devices can be, for example, base stations, mobile stations, etc.
[0333] The communication module 2013 can wirelessly transmit to an external device at least one of the signals input to the electronic control unit 2010 from the various sensors 2021-2028, information obtained based on those signals, and information obtained via the information service unit 2012 based on input from an external source (user). The electronic control unit 2010, the various sensors 2021-2028, and the information service unit 2012 can also be referred to as input units that receive input. For example, the PUSCH transmitted by the communication module 2013 can contain information based on the aforementioned input.
[0334] The communication module 2013 receives various information (traffic information, signal information, vehicle-to-vehicle information, etc.) sent from external devices and displays it on the information service unit 2012 provided by the vehicle.
