Description

[Technical field]

[0001] The present disclosure relates to a user equipment, a base station and a method. [Background technology]

[0002] In Release 17 of the 3GPP (3rd Generation Partnership Project), a work item on Measurement Gap Enhancement has been launched with the aim of improving the efficiency of RRM (Radio Resource Management) functions in user equipment (UE) and networks (Non-Patent Document 1).

[0003] For example, Non-Patent Documents 2 to 6 describe discussions on signaling and procedures related to a P-MG (Pre-configured Measurement Gap) that is different from a conventional MG (Legacy Measurement Gap). Unlike a conventional MG, a P-MG can be activated or deactivated.

[0004] In particular, Non-Patent Document 5 describes a discussion of the relationship between conventional MGs and P-MGs, and the criteria for activating or deactivating P-MGs. [Prior art documents] [Non-patent literature]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In this specification and the drawings, elements that can be similarly described may be denoted by the same reference numerals, and repeated description may be omitted.

[0015] The explanation will be given in the following order: 1. System Configuration 2. User device configuration 3. Base Station Configuration 4. Example of operation 5. Variations

[0016] <1. System configuration> An example of a configuration of a system 1 according to an embodiment of the present disclosure will be described with reference to Fig. 1. Referring to Fig. 1, the system 1 includes a user equipment 100 and a base station 200.

[0017] For example, the system 1 is a system that complies with the Technical Specification (TS) of the Third Generation Partnership Project (3GPP). More specifically, for example, the system 1 is a system that complies with the TS of 5G or New Radio (NR). Of course, the system 1 is not limited to this example.

[0018] (1)UE100 The UE 100 communicates with a base station. For example, the UE 100 communicates with the base station 200 when the UE 100 is located within a coverage area 10 of the base station 200.

[0019] For example, the UE 100 communicates with a base station (e.g., the base station 200) using a protocol stack of a Radio Access Network (RAN). For example, the protocol stack includes Radio Resource Control (RRC), Service Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), Medium Access Control (MAC), and a Physical (PHY) layer protocol. Alternatively, the protocol stack may include only some of these protocols rather than all of them.

[0020] In addition, the UE 100 measures a signal transmitted from a base station using the MG. The MG is configured for inter-frequency, inter-system, or intra-frequency measurement. The UE 100 measures a signal by switching the frequency or the system during the configured MG period.

[0021] For example, referring to the example of Fig. 2, the UE 100 can measure a signal from the base station 200B having a different communication frequency from the connected base station 200A. Specifically, the UE 100 does not communicate with the base station 200A during the set MG period, receives a signal transmitted from the base station 200B, and measures the reception quality of the signal. For example, the UE 100 may switch the connection from the base station 200A to the base station 200B when the reception quality of the signal from the base station 200B is better than the reception quality of the signal from the base station 200A.

[0022] (2) Base station 200 The base station 200 is a node of the RAN and communicates with UEs (eg, UE 100) located within the coverage area 10 of the base station 200.

[0023] For example, the base station 200 communicates with a UE (eg, the UE 100) using the above protocol stack.

[0024] For example, the base station 200 is a gNB. The gNB is a node that provides NR user plane and control plane protocol terminations towards the UE and is connected to a 5G Core Network (5GC) via an NG interface. Alternatively, the base station 200 may be an en-gNB. The en-gNB is a node that provides NR user plane and control plane protocol terminations towards the UE and operates as a secondary node in E-UTRA-NR Dual Connectivity (EN-DC).

[0025] The base station 200 may include a plurality of nodes. The plurality of nodes may include a first node hosting a higher layer included in the protocol stack, and a second node hosting a lower layer included in the protocol stack. The higher layer may include RRC, SDAP, and PDCP, and the lower layer may include RLC, MAC, and a PHY layer. The first node may be a central unit (CU), and the second node may be a distributed unit (DU). The plurality of nodes may include a third node performing processing below the PHY layer, and the second node may perform processing above the PHY layer. The third node may be a radio unit (RU).

[0026] Alternatively, the base station 200 may be one of the plurality of nodes, and may be connected to other units of the plurality of nodes.

[0027] The base station 200 may be an Integrated Access and Backhaul (IAB) donor or an IAB node.

[0028] <2. User device configuration> An example of the configuration of the UE 100 according to the embodiment of the present disclosure will be described with reference to FIG. 3 and FIG.

[0030] The wireless communication unit 110 transmits and receives signals wirelessly. For example, the wireless communication unit 110 receives a signal from a base station and transmits the signal to the base station. For example, the wireless communication unit 110 receives a signal from another UE and transmits the signal to the other UE.

[0031] The storage unit 120 stores various information for the UE 100.

[0032] The processing unit 130 provides various functions of the UE 100.

The processing unit 130 may further include other components in addition to these components. That is, the processing unit 130 may also perform operations in addition to the operations of these components. Specific operations of the information acquisition unit 131, the control unit 133, and the communication processing unit 135 will be described in detail later.

[0033] For example, the processing unit 130 (the communication processing unit 135) communicates with a base station (for example, the base station 200) or other UE via the wireless communication unit 110.

[0034] (2) Hardware Configuration Next, an example of a hardware configuration of the UE 100 according to the embodiment of the present disclosure will be described with reference to Fig. 4. Referring to Fig. 4, the UE 100 includes an antenna 181, an RF (radio frequency) circuit 183, a processor 185, a memory 187, and a storage 189.

[0035] The antenna 181 converts a signal into a radio wave and radiates the radio wave into space. The antenna 181 also receives radio waves in space and converts the radio waves into a signal.

[0037] The processor 185 performs digital processing of signals transmitted and received via the antenna 181 and the RF circuitry 183. The digital processing includes processing of a protocol stack of the RAN. The processor 185 may include multiple processors or may be a single processor. The multiple processors may include a baseband processor that performs the digital processing and one or more processors that perform other processing.

[0038] Memory 187 stores programs executed by processor 185, parameters related to the programs, and various other information. Memory 187 may include at least one of a read only memory (ROM), an erasable programmable read only memory (EPROM), an electrically erasable programmable read only memory (EEPROM), a random access memory (RAM), and a flash memory. All or a part of memory 187 may be included in processor 185.

[0042] Considering the above hardware configuration, UE 100 may include a memory (i.e., memory 187) that stores a program, and one or more processors (i.e., processor 185) that can execute the program, and the one or more processors may execute the program to perform the operation of processing unit 130. The program may be a program for causing the processor to execute the operation of processing unit 130.

[0043] <3. Base station configuration> An example of the configuration of the base station 200 according to the embodiment of the present disclosure will be described with reference to FIGS.

[0044] (1) Functional configuration First, an example of a functional configuration of the base station 200 according to the embodiment of the present disclosure will be described with reference to Fig. 5. Referring to Fig. 5, the base station 200 includes a wireless communication unit 210, a network communication unit 220, a storage unit 230, and a processing unit 240.

[0045] The wireless communication unit 210 transmits and receives signals wirelessly. For example, the wireless communication unit 210 receives signals from a UE and transmits signals to the UE.

[0046] The network communication unit 220 receives signals from the network and transmits signals to the network.

[0047] The storage unit 230 stores various information for the base station 200 .

[0048] The processing unit 240 provides various functions of the base station 200. The processing unit 240 includes an information acquisition unit 241, a control unit 243, and a communication processing unit 245. The processing unit 240 may further include other components in addition to these components. That is, the processing unit 240 may also perform operations other than the operations of these components. The specific operations of the information acquisition unit 241, the control unit 243, and the communication processing unit 245 will be described in detail later.

[0049] For example, the processing unit 240 (communication processing unit 245) communicates with a UE (for example, the UE 100) via the wireless communication unit 210. For example, the processing unit 240 (communication processing unit 245) communicates with another node (for example, a network node in a core network or another base station) via the network communication unit 220.

[0050] (2) Hardware Configuration Next, an example of a hardware configuration of the base station 200 according to an embodiment of the present disclosure will be described with reference to Fig. 6. Referring to Fig. 6, the base station 200 includes an antenna 281, an RF circuit 283, a network interface 285, a processor 287, a memory 289, and a storage 291.

[0051] Antenna 281 converts signals into radio waves and radiates the radio waves into space. Antenna 281 also receives radio waves in space and converts the radio waves into signals. Antenna 281 may include a transmitting antenna and a receiving antenna, or may be a single antenna for transmitting and receiving. Antenna 281 may be a directional antenna and may include multiple antenna elements.

[0052] The RF circuit 283 performs analog processing of signals transmitted and received via the antenna 281. The RF circuit 283 may include a high-frequency filter, an amplifier, a modulator, a low-pass filter, and the like.

[0053] The network interface 285 is, for example, a network adapter, and transmits signals to and receives signals from the network.

[0054] The processor 287 performs digital processing of signals transmitted and received via the antenna 281 and the RF circuitry 283. The digital processing includes processing of a protocol stack of the RAN. The processor 287 also processes signals transmitted and received via the network interface 285. The processor 287 may include multiple processors or may be a single processor. The multiple processors may include a baseband processor that performs the digital processing and one or more processors that perform other processing.

[0055] The memory 289 stores programs executed by the processor 287, parameters related to the programs, and various other information. The memory 289 may include at least one of a ROM, an EPROM, an EEPROM, a RAM, and a flash memory. All or a part of the memory 289 may be included within the processor 287.

[0056] The storage 291 stores various information. The storage 291 may include at least one of an SSD and an HDD.

In this case, a part or all of the processing unit 240 may operate as a virtual machine on a physical machine (i.e., hardware) including a processor, a memory, and the like, and on a hypervisor.

[0059] Considering the above hardware configuration, base station 200 may include a memory (i.e., memory 289) that stores a program, and one or more processors (i.e., processor 287) that can execute the program, and the one or more processors may execute the program to perform the operation of processing unit 240. The program may be a program for causing a processor to execute the operation of processing unit 240.

[0060] <4. Example of operation> An example of the operation of the UE 100 and the base station 200 according to the embodiment of the present disclosure will be described with reference to FIGS.

[0061] (1) Operation of UE100 The UE 100 receives MG setting information from the base station 200. The UE 100 sets the MG based on the common setting information and the P-MG setting information included in the received MG setting information. The operation of the UE 100 and related information will be described in detail below.

[0062] (1-1) Receive MG setting information The UE 100 receives the MG setting information from the base station 200. Specifically, the UE 100 (communication processing unit 135) receives an RRC message including the MG setting information from the base station 200. The UE 100 (information acquisition unit 131) acquires the MG setting information included in the RRC message.

[0063] The MG setting information includes common setting information used in the conventional MG (first MG) and the P-MG (second MG), and P-MG setting information indicating that the P-MG is set. Specifically, the P-MG setting information indicates activation or deactivation of the P-MG when the P-MG is set. Also, the P-MG setting information indicates that the P-MG is not set when the P-MG is not set.

[0064] For example, the MG setting information is MeasGapConfig, which is an RRC IE (Information Element). The common setting information includes at least one of the parameters included in GapConfig that are set in MeasGapConfig. The P-MG setting information is included in GapConfig. MeasGapConfig indicates whether MG is set or not, and can take the value of setup or release.

[0065] Referring to information 21 in Fig. 7, MeasGapConfig includes parameters such as gapUE, gapFR1, and gapFR2. The parameters are setting presence / absence parameters indicating whether or not MG is set for the unit in which MG is set, and can take the value of setup or release. When gapUE is setup, MG is set for each UE (per UE), and when gapFR1 and gapFR2 are setup, MG is set for each FR (per frequency range). When the setting presence / absence parameter is setup, GapConfig, which is an IE, is set as a value. The setting parameters of MG for each unit are included in GapConfig.

[0066] Referring to information 23 in FIG. 8, GapConfig includes parameters such as gapOffset, mgl, mgrp, mgta, refServCellIndicator, refFR2ServCellAsyncCA-r16, and mgl-r16 as common setting information. gapOffset indicates an offset of a gap pattern with MGRP (Measurement Gap Repetition Period). mgl and mgl-r16 indicate the length of MG, i.e., MGP (Measurement Gap Length). mgrp indicates the repetition period of MG, i.e., MGRP. mgta indicates the timing advance of MG. refServCellIndicator and refFR2ServCellAsyncCA-r16 indicate the SFN (System Frame Number) and subframe of the serving cell used in MG calculation. The above parameters as common setting information can be used in both conventional MG and P-MG. The common setting information may be at least one of the above parameters.

[0067] GapConfig also includes preconfiguredGap-r17 as configuration information of the P-MG. preconfiguredGap-r17 indicates whether the P-MG is configured or not, and can take the value of setup or release. If preconfiguredGap-r17 is setup, the P-MG is configured. In other words, the MG is preconfigured. In this case, PreconfiguredGapConfig-r17, which is an IE, is set as a value. PreconfiguredGapConfig-r17 includes preconfiguredGapState-r17. preconfiguredGapState-r17 indicates whether the P-MG is activated or deactivated. preconfiguredGap-r17 as the configuration information of the P-MG is optional.

[0068] In this way, when the P-MG is set, the setting information of the P-MG indicates activation or deactivation of the P-MG. This allows the information indicating the activation or deactivation of the P-MG to be included in the MG setting information only when the P-MG is set. This makes it possible to improve the efficiency of signaling. In addition, by managing the activation or deactivation of the MG as a state, it is possible to control whether or not to apply the MG without discarding the MG setting.

[0069] Also, when the P-MG is not set, the setting information of the P-MG indicates that the P-MG is not set. This makes it possible to clearly indicate that the P-MG is not set. Also, it is possible to clearly indicate whether the MG to be applied is the conventional MG or the P-MG. Therefore, inconsistency in the MG setting information between the UE 100 and the base station 200 can be suppressed.

[0070] Moreover, the MG setting information is MeasGapConfig, the common setting information includes at least one of the parameters included in GapConfig set in MeasGapConfig, and the setting information of the P-MG is included in GapConfig. This makes it possible to transmit the setting information of the P-MG to the UE 100 while using the MG setting information used in the conventional MG. Furthermore, since the setting information of the P-MG is optional, it is possible to maintain the compatibility of the MG setting information with the conventional MG.

[0071] The RRC message including the MG configuration information may be an RRCReconfiguration message or an RRCResume message.

[0072] This makes it possible to use existing signaling between the UE and the base station to transmit MG setting information including P-MG setting information from the base station 200 to the UE 100. This makes it possible to prevent the addition of new signaling.

[0073] In addition, the RRC message including the MG setting information including the P-MG setting information may be an additionally defined RRC message for transmitting the MG setting information including the P-MG setting information. In this case, the MG setting information including the P-MG setting information can be transmitted to the UE 100 without changing the existing RRC message.

[0074] (1-2) Setting MG The UE 100 sets an MG based on the MG setting information. Specifically, the UE 100 (control unit 133) sets a conventional MG or a P-MG based on the MG setting information included in the RRC message received from the base station 200.

[0075] More specifically, when the P-MG setting information included in the MG setting information indicates that the P-MG is set, the UE 100 sets the P-MG. Also, when the P-MG setting information indicates that the P-MG is not set, the UE 100 sets the conventional MG.

[0076] For example, when preconfiguredGap-r17 included in Gapconfig illustrated in Fig. 8 is "setup," UE 100 sets P-MG. That is, PreconfiguredGapConfig-r17 including preconfiguredGapState-r17 set to "activation" or "deactivation" as a parameter is set.

[0077] Also, when preconfiguredGap-r17 is released, UE100 sets the conventional MG. Therefore, PreconfiguredGapConfig-r17 is not set. That is, the mechanism of P-MG is not applied to MG. Therefore, MG is not controlled using the activation state. In other words, it can be said that MG is always in an activated state. In this way, when the setting information of P-MG indicates that P-MG is not set, compatibility with the conventional MG can be maintained by setting the conventional MG.

[0078] (2) Operation of Base Station 200 The base station 200 sets either the conventional MG or the P-MG. The base station 200 transmits MG setting information including common setting information and P-MG setting information to the UE 100. The operation of the base station 200 and related information will be described in detail below. Note that detailed description of contents that are substantially the same as those described in the operation of the UE 100 will be omitted.

[0079] (2-1) Setting MG The base station 200 sets either the conventional MG or the P-MG. Specifically, the base station 200 (control unit 243) selectively sets the conventional MG or the P-MG based on conditions. For example, the conventional MG or the P-MG is selectively set based on the presence or absence of an MG setting request from the UE 100, or the adaptability or capability of the UE 100 for the P-MG.

[0080] The base station 200 sets the common setting information and the P-MG setting information. For example, the base station 200 sets MeasGapConfig as the MG setting information, sets one of the parameters included in GapConfig as the common setting information, and sets preconfiguredGap-r17 as the P-MG setting information.

[0081] Furthermore, when P-MG is set, the base station 200 sets preconfiguredGap-r17 to "setup" and sets PreconfiguredGapConfig-r17 including preconfiguredGapState-r17 set to "activation" or "deactivation" as a parameter. When P-MG is not set, the base station 200 sets preconfiguredGap-r17 to "release."

[0082] (2-2) Send MG setting information The base station 200 transmits the MG setting information to the UE 100. Specifically, the base station 200 (information acquisition unit 241) acquires the MG setting information. The base station 200 (communication processing unit 245) transmits an RRC message including the acquired MG setting information to the UE 100.

[0083] For example, the base station 200 transmits an RRC message including MG setting information including common setting information for the configured MG and setting information of the P-MG to the UE 100. For example, the RRC message including the MG setting information may be an RRCReconfiguration message or an RRCResume message.

[0084] (3) Processing flow 9 and 10, an example of a process according to an embodiment of the present disclosure will be described.

[0085] First, an example of a schematic flow of processing of the system 1 according to an embodiment of the present disclosure will be described with reference to FIG.

[0086] The base station 200 sets the MG (S310). For example, the base station 200 sets the P-MG. That is, the common setting information and the setting information of the P-MG are set.

[0087] The base station 200 transmits an RRC message including MG setting information to the UE 100 (S320). For example, the base station 200 transmits, to the UE 100, an RRCReconfiguration message or an RRCResume message including measGapConfig as MG setting information including common setting information and P-MG setting information.

[0088] The UE 100 transmits a response message to the received RRC message to the base station 200 (S330). For example, when the UE 100 receives an RRCReconfiguration message or an RRCResume message including measGapConfig from the base station 200, the UE 100 transmits an RRCReconfigurationComp message or an RRCResumeComp message to the base station 200. Note that, if the activation state of the P-MG is changed at this timing, the response message may include information indicating the activation state of the P-MG (i.e., information indicating activation or deactivation).

[0089] The UE 100 acquires the MG setting information from the received RRC message (S340). For example, the UE 100 acquires measGapConfig as the MG setting information from the received RRCReconfiguration message or RRCResume message.

[0090] The UE 100 configures the MG based on the common configuration information and the P-MG configuration information included in the acquired MG configuration information (S350). For example, the UE 100 configures either the conventional MG or the P-MG based on the P-MG configuration information included in the acquired measGapConfig. Details of the MG configuration will be described later with reference to FIG. 10.

[0091] Next, with reference to FIG. 10, an example of a schematic flow of MG configuration in the UE 100 according to the embodiment of the present disclosure will be described.

[0092] The UE 100 determines whether or not the configuration information of the P-MG indicates release (S410). For example, the UE 100 determines whether the preconfiguredGap-r17 included in the GapConfig set as a parameter value set to setup among gapUE, gapFR1, and gapFR2 in the measGapConfig is setup or release.

[0093] When the setting information of the P-MG does not indicate release, the UE 100 judges whether the setting information of the P-MG indicates activated (S420). For example, when the preconfiguredGap-r17 is setup, the UE 100 judges whether the preconfiguredGapState-r17 included in the PreconfiguredGapConfig-r17 set as the value of the preconfiguredGap-r17 is activated or deactivated.

[0094] When the setting information of the P-MG indicates activated, the UE 100 sets the MG in the activated state (S430). For example, when the preconfiguredGapState-r17 is activated, the UE 100 sets the MG whose activation state is activated. In other words, the UE 100 operates as if the P-MG is activated.

[0095] If the configuration information of the P-MG does not indicate activated, the UE 100 configures the MG in the deactivated state (S440). If the preconfiguredGapState-r17 is deactivated, the UE 100 configures the MG whose activation state is deactivated. In other words, the UE 100 operates as if the P-MG is deactivated.

[0096] When the setting information of the P-MG indicates release, the UE 100 sets the conventional MG (S450). For example, when the preconfiguredGap-r17 is release, the UE 100 sets the conventional MG. That is, the PreconfiguredGapConfig-r17 is not set. In this case, the MG setting in the measGapConfig continues to be applied until the measGapConfig is released, as in the conventional case.

[0097] The above P-MG settings may be reflected in the TS. Information 25 in Fig. 11 is an example of how the P-MG settings are reflected in the TS. Of course, the manner in which the P-MG settings are reflected in the TS is not limited to this.

[0098] (4) Effects Thus, according to the embodiment of the present disclosure, an RRC message including MG setting information is transmitted from the base station to the UE 100, and the MG setting information includes common setting information used in the conventional MG and P-MG, and setting information of the P-MG indicating that the P-MG is set. This makes it possible to distinguish whether the MG setting information is for the conventional MG or for the P-MG while using the same MG setting information between the conventional MG and the P-MG. Therefore, it is possible to avoid a conflict between the settings of two coexisting MGs. In addition, by utilizing the MG setting information used in the conventional MG, the same MG setting information can be used for the conventional MG and the P-MG. In other words, it can be said that the setting of the conventional MG can be transformed into the setting of the P-MG, or the setting of the P-MG can be transformed into the setting of the conventional MG.

[0099] In addition, if different and independent MG setting information is used between the conventional MG and the P-MG, it may be necessary to define additional operations to avoid a conflict between the settings of the two MGs. For example, when the P-MG is set, the network (i.e., the base station) is required to control so that the conventional MG is not set, and conversely, when the conventional MG is set, the P-MG is not set. In contrast, according to the embodiment of the present disclosure, it is possible to avoid a conflict between the settings of two coexisting MGs without the above-mentioned additional operations.

[0100] <5. Modifications> First to fourth modified examples according to the embodiment of the present disclosure will be described below. Note that two or more of these modified examples may be combined.

[0101] (1) First Modification: Second Example of P-MG Setting Information In the above-described embodiment of the present disclosure, the setting information of the P-MG indicates activation or deactivation of the P-MG when the P-MG is set. However, the setting information of the P-MG according to the embodiment of the present disclosure is not limited to this example.

[0102] As a first modification of the embodiment of the present disclosure, information other than the configuration information of the P-MG may indicate activation or deactivation of the P-MG.

[0103] Specifically, the setting information of the P-MG indicates whether or not the P-MG is set up, and the P-MG status information, which is separate from the setting information of the P-MG, indicates the activation or deactivation of the P-MG.

[0104] For example, referring to information 27 in FIG. 12, GapConfig includes preconfiguredGap-r17 as P-MG configuration information and preconfiguredGapState-r17 as P-MG state information as parameters. preconfiguredGap-r17 indicates whether the P-MG is configured or not, and can take a value of TRUE or FALSE. preconfiguredGapState-r17 indicates whether the P-MG is activated or deactivated. preconfiguredGapState-r17 is configured when preconfiguredGap-r17 is TRUE.

[0105] An example of a process flow according to this modified example will be described with reference to Fig. 10. Note that a description of processes that are substantially the same as the processes according to the embodiment of the present disclosure described above will be omitted.

[0106] Instead of S410, the UE 100 determines whether the setting information of the P-MG indicates TRUE. For example, the UE 100 determines whether preconfiguredGap-r17 included in GapConfig is TRUE or FALSE.

[0107] Instead of S420, when the setting information of the P-MG indicates TRUE, the UE 100 determines whether the P-MG state information indicates activated. For example, when the preconfiguredGap-r17 is TRUE, the UE 100 determines whether the preconfiguredGapState-r17 is activated or deactivated.

[0108] Instead of S430, if the P-MG state information indicates activated, the UE 100 sets the MG in the activated state.

[0109] Alternatively to S440, if the P-MG state information does not indicate activated, the UE 100 sets the MG to a deactivated state.

[0110] Instead of S450, if the configuration information of the P-MG indicates FALSE, the UE 100 configures the conventional MG.

[0111] The above P-MG settings may be reflected in the TS. Information 29 in Fig. 13 is an example of how the P-MG settings are reflected in the TS. Of course, the manner in which the P-MG settings are reflected in the TS is not limited to this.

[0112] Thus, according to the first modification of the embodiment of the present disclosure, information other than the setting information of the P-MG indicates activation or deactivation of the P-MG. This makes it possible to control the activation state of the P-MG without the setting information of the P-MG being continuously held in the UE 100. In addition, by separating the setting information of the P-MG from the P-MG state information, it is possible to indicate the activation state of the P-MG to the UE 100 regardless of the setting of the P-MG. For example, the activation state can be indicated at the RRC layer or the PHY layer, or can be changed by another trigger (for example, BWP switching based on a timer).

[0113] (2) Second Modification: Third Example of P-MG Setting Information In the embodiment of the present disclosure described above, the setting information of the P-MG indicates whether or not the P-MG is set. However, the setting information of the P-MG according to the embodiment of the present disclosure is not limited to this example.

[0114] As a second modification of the embodiment of the present disclosure, the setting information of the P-MG may indicate whether or not the P-MG is set depending on the presence or absence.

[0115] Specifically, the configuration information of the P-MG may not be included in the MG configuration information if the P-MG is not configured. More specifically, the configuration information of the P-MG may be information indicating an activation state. For example, the configuration information of the P-MG may be preconfiguredGapState-r17 as shown in FIG. 8. preconfiguredGapState-r17 is included in GapConfig if the P-MG is configured, and is not included in GapConfig if the P-MG is not configured.

[0116] In this way, according to the second modification of the embodiment of the present disclosure, when the P-MG is not configured, the P-MG setting information is not included in the MG setting information. This makes it possible to reduce the amount of communication in signaling while indicating whether the P-MG is configured or not.

[0117] (3) Third modification: Independent setting for conventional MG and P-MG In the above-described embodiment of the present disclosure, the MG setting information is shared between the conventional MG and the P-MG. However, the MG setting information according to the embodiment of the present disclosure is not limited to this example.

[0118] As a third modification of the embodiment of the present disclosure, the MG configuration information may be defined separately for each of the conventional MG and the P-MG.

[0119] Specifically, the MG setting information for the conventional MG and the MG setting information for the P-MG may be included in the Measurement setting information independently of each other. For example, MeasConfig may include measGapConfig for the conventional MG and measGapConfig for the P-MG.

[0120] The MG setting information for the conventional MG is the conventional MG setting information. The MG setting information for the P-MG includes the above-mentioned P-MG setting information in addition to the conventional MG setting information.

[0121] The MG setting information for the P-MG may partially include the setting information of the P-MG as described above. Specifically, only information indicating the activation state of the P-MG may be included in the MG setting information. For example, instead of preconfiguredGap-r17 shown in FIG. 8, only preconfiguredGapState-r17 may be included in GapConfig. Alternatively, information indicating the activation state of the P-MG may not be included in the MG setting information, but may be included directly below Measurement setting information. For example, preconfiguredGapState-r17 shown in FIG. 8 may be included in parallel with measGapConfig directly below MeasConfig.

[0122] The network (i.e., the base station 200) configures only one MG during MG configuration. That is, the base station 200 generates only one of the MG configuration information for the conventional MG and the MG configuration information for the P-MG.

[0123] Alternatively, UE 100 may select one MG setting information. For example, when MG setting information for a conventional MG and MG setting information for a P-MG are included in the Measurement setting information, UE 100 may leave the MG setting information for the P-MG and discard the conventional MG setting information. Note that, when only one of the MG setting information for the conventional MG and the MG setting information for the P-MG is included, the MG is set based on the included MG setting information.

[0124] In this way, according to the third modified example of the embodiment of the present disclosure, the MG setting information is defined separately for each of the conventional MG and the P-MG. This allows the MG setting information for the conventional MG and the MG setting information for the P-MG to be managed independently. Therefore, different settings can be easily applied to the conventional MG and the P-MG. For example, it becomes easy to distinguish and manage settings used only for the P-MG or only for the conventional MG.

[0125] (4) Fourth Variation: Compliance with Other TS In the above-described example of the embodiment of the present disclosure, the system 1 is a system that complies with 5G or NR TS. However, the system 1 according to the embodiment of the present disclosure is not limited to this example.

[0126] In a fourth variant of the embodiment of the present disclosure, the system 1 may be a system compliant with other TS of 3GPP. As an example, the system 1 may be a system compliant with TS of LTE (Long Term Evolution), LTE-A (LTE Advanced), or 4G, and the base station 200 may be an evolved Node B (eNB). Alternatively, the base station 200 may be an ng-eNB. As another example, the system 1 may be a system compliant with TS of 3G, and the base station 200 may be a Node B. As yet another example, the system 1 may be a system compliant with TS of next generation (e.g., 6G).

[0127] Alternatively, the system 1 may be a system conforming to a TS of another standardization organization for mobile communications.

[0128] Although the embodiment of the present disclosure has been described above, the present disclosure is not limited to the embodiment. It will be understood by those skilled in the art that the embodiment is merely an example, and that various modifications are possible without departing from the scope and spirit of the present disclosure.

[0129] For example, the steps in the processes described herein do not necessarily have to be performed chronologically according to the order depicted in the flowcharts or sequence diagrams. For example, the steps in the processes may be performed in an order different from that depicted in the flowcharts or sequence diagrams, or may be performed in parallel. Also, some of the steps in the processes may be deleted, and additional steps may be added to the processes.

[0130] For example, a method including the operation of one or more components of the apparatus described in this specification may be provided, or a program for causing a computer to execute the operation of the components may be provided. Also, a non-transitory tangible computer-readable storage medium having the program recorded thereon may be provided.

[0133] For example, in this disclosure, "obtain / acquire" may mean obtaining information from stored information, obtaining information from information received from other nodes, or obtaining information by generating the information.

[0134] For example, in this disclosure, "include" and "comprise" do not mean including only the items listed, but may include only the items listed, or may include additional items in addition to the items listed.

[0135] For example, in this disclosure, "or" does not mean an exclusive or, but rather a logical or.
