Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is based on Japanese Application No. 2021-171755, filed on October 20, 2021, the contents of which are incorporated herein by reference. [Technical Field]

[0002] The present disclosure relates to an apparatus, a base station and a method. [Background technology]

[0003] 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).

[0004] For example, Non-Patent Documents 2 to 6 describe discussions on signaling and procedures related to a P-MG (Pre-configured Measurement Gap), which is different from a conventional MG (Legacy Measurement Gap). Unlike a conventional MG, a P-MG can be activated or deactivated.

[0005] In particular, Non-Patent Document 5 describes a discussion on the relationship between conventional MGs and P-MGs, and on the criteria for activating or deactivating P-MGs.

[0006] Furthermore, the current Technical Specification (TS) defines a scheme for sharing MGs (Non-Patent Document 7). In MG sharing, MGs are shared when there is a duplicate MG. MG sharing can be configured together with the MG configuration. The MG sharing configuration can be discarded together with the discarding of the MG configuration.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In this specification and drawings, elements that can be similarly described will be designated by the same reference numerals, and redundant description will be omitted.

[0017] The explanation will be given in the following order: 1. System Configuration 2. User device configuration 3. Base Station Configuration 4. First embodiment (MG setting information for P-MG) 5. Second embodiment (MG activation status management) 6. Third embodiment (linking activation of MG and MG sharing)

[0018] <1. System configuration> An example of the 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.

[0019] For example, system 1 is a system that complies with 3GPP TS. More specifically, system 1 is a system that complies with 5G or NR (New Radio) TS. Of course, system 1 is not limited to this example. System 1 may also be a system that complies with other 3GPP TS. As an example, system 1 may be a system that complies with LTE, LTE-Advanced (LTE-A), or 4G TS, and base station 200 may be an eNB (evolved Node B). Alternatively, base station 200 may be an ng-eNB. As another example, system 1 may be a system that complies with 3G TS, and base station 200 may be a Node B. As yet another example, system 1 may be a system that complies with next-generation (e.g., 6G) TS. Alternatively, system 1 may be a system that complies with TS of another standardization organization for mobile communications.

[0020] (1)UE100 The UE 100 communicates with a base station 200. 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.

[0021] 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.

[0022] The UE 100 also measures signals transmitted from a base station using an MG. The MG is configured for inter-frequency, inter-system, or intra-frequency measurements. The UE 100 measures signals by switching frequencies or systems during the configured MG period.

[0023] 2, the UE 100 can measure a signal from the base station 200B, which has a different communication frequency from the base station 200A to which it is connected. Specifically, the UE 100 does not communicate with the base station 200A during the set MG period, but receives a signal transmitted from the base station 200B, and measures the reception quality of the signal. For example, if 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, the UE 100 may switch the connection from the base station 200A to the base station 200B.

[0024] (2) Base station 200 The base station 200 is a node of the RAN and communicates with UEs (eg, UEs 100) located within the coverage area 10 of the base station 200.

[0025] For example, the base station 200 communicates with a UE (eg, the UE 100) using the above protocol stack.

[0026] For example, base station 200 is a gNB. The gNB is a node that provides NR user plane and control plane protocol terminations toward the UE and is connected to a 5G Core Network (5GC) via an NG interface. Alternatively, base station 200 may be an en-gNB. The en-gNB is a node that provides NR user plane and control plane protocol terminations toward the UE and operates as a secondary node in E-UTRA-NR Dual Connectivity (EN-DC).

[0027] Base station 200 may include multiple nodes. The multiple 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 multiple nodes may include a third node that performs 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).

[0028] Alternatively, the base station 200 may be one of the plurality of nodes, or may be connected to other units of the plurality of nodes.

[0029] Base station 200 may be an Integrated Access and Backhaul (IAB) donor or an IAB node.

[0030] <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 FIGS.

[0031] (1) Functional configuration First, an example of a functional configuration of the UE 100 according to the embodiment of the present disclosure will be described with reference to Fig. 3.

The specific operations of the information acquisition unit 131, the control unit 133, and the communication processing unit 135 will be described in detail later.

[0035] For example, the processing unit 130 (communication processing unit 135) communicates with a base station (for example, base station 200) or other UE via the wireless communication unit 110.

[0036] (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.

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.

[0040] 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 within processor 185.

[0046] (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.

[0047] The wireless communication unit 210 transmits and receives signals wirelessly. For example, the wireless communication unit 210 receives signals from UEs and transmits signals to UEs.

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.

[0051] For example, the processing unit 240 (communication processing unit 245) communicates with a UE (for example, UE 100) via the radio 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.

[0052] (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.

[0053] 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 both transmission and reception.

[0062] 4. First Embodiment A first embodiment of the present disclosure will be described. In the first embodiment, MG setting information for a P-MG commonly uses MG setting information for a conventional MG.

[0063] <4-1. Example of operation> An example of the operation of the UE 100 and the base station 200 according to the first embodiment of the present disclosure will be described with reference to FIGS.

[0064] (1) Operation of UE100 UE 100 receives MG setting information from base station 200. UE 100 sets up an MG based on common setting information and P-MG setting information included in the received MG setting information. The operation of UE 100 and related information will be described in detail below.

[0065] (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.

[0066] 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 to be set. Specifically, the P-MG setting information indicates activation or deactivation of the P-MG when the P-MG is set. Furthermore, the P-MG setting information indicates that the P-MG is not to be set when the P-MG is not set.

[0067] 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 an MG is set, and can take the value of setup or release.

[0068] Referring to information 21 in Fig. 7, MeasGapConfig includes parameters such as gapUE, gapFR1, and gapFR2. These parameters are setting / non-setting 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 / non-setting parameter is setup, GapConfig, which is an IE, is set as a value. The setting parameters for MG for each unit are included in GapConfig.

[0069] Referring to information 23 in FIG. 8 , GapConfig includes parameters such as gapOffset, mgl, mgrp, mgta, refServCellIndicator, refFR2ServCellAsyncCA-r16, and mgl-r16 as common configuration information. gapOffset indicates the offset of the gap pattern accompanied by MGRP (Measurement Gap Repetition Period). mgl and mgl-r16 indicate the length of the MG, i.e., MGP (Measurement Gap Length). mgrp indicates the MG repetition period, i.e., MGRP. mgta indicates the MG timing advance. 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 configuration information can be used in both conventional MG and P-MG. Note that the common configuration information may be at least one of the above parameters.

[0070] GapConfig also includes preconfiguredGap-r17 as configuration information for 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, the value of PreconfiguredGapConfig-r17, which is an IE, is set. PreconfiguredGapConfig-r17 includes preconfiguredGapState-r17. preconfiguredGapState-r17 indicates whether the P-MG is activated or deactivated. preconfiguredGap-r17 as configuration information for the P-MG is optional.

[0071] In this way, when a P-MG is configured, the configuration information of the P-MG indicates activation or deactivation of the P-MG. This allows the information indicating activation or deactivation of the P-MG to be included in the MG configuration information only when the P-MG is configured. This makes it possible to improve the efficiency of signaling. Furthermore, 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 configuration.

[0072] Furthermore, when a P-MG is not configured, the P-MG configuration information indicates that a P-MG is not configured. This makes it possible to clearly indicate that a P-MG is not configured. It is also possible to clearly indicate whether the MG to be applied is a conventional MG or a P-MG. This makes it possible to suppress inconsistencies in the MG configuration information between the UE 100 and the base station 200.

[0073] Furthermore, the MG configuration information is MeasGapConfig, the common configuration information includes at least one of the parameters included in GapConfig that is set in MeasGapConfig, and the configuration information of the P-MG is included in GapConfig. This makes it possible to transmit the configuration information of the P-MG to UE 100 while using the MG configuration information used in the conventional MG. Furthermore, since the configuration information of the P-MG is optional, it is possible to maintain compatibility of the MG configuration information with the conventional MG.

[0074] The RRC message containing the MG configuration information may be an RRCReconfiguration message or an RRCResume message.

[0075] This allows MG setting information including P-MG setting information to be transmitted from base station 200 to UE 100 by using existing signaling between the UE and the base station, thereby preventing the addition of new signaling.

[0076] The RRC message including the MG configuration information including the P-MG configuration information may be an additionally defined RRC message for transmitting the MG configuration information including the P-MG configuration information. In this case, the MG configuration information including the P-MG configuration information can be transmitted to the UE 100 without changing the existing RRC message.

[0077] (1-2) Set 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.

[0078] More specifically, UE 100 sets up a P-MG when the P-MG setting information included in the MG setting information indicates that a P-MG is to be set up. Also, UE 100 sets up a conventional MG when the P-MG setting information indicates that a P-MG is not to be set up.

[0079] For example, when preconfiguredGap-r17 included in Gapconfig shown 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.

[0080] Also, if preconfiguredGap-r17 is released, UE 100 configures the conventional MG. Therefore, PreconfiguredGapConfig-r17 is not configured. That is, the P-MG mechanism is not applied to the MG. Therefore, the MG is not controlled using the activation state. In other words, it can be said that the MG is always in an activated state. In this way, when the configuration information of the P-MG indicates that the P-MG is not configured, the conventional MG is configured, thereby maintaining compatibility with the conventional MG.

[0081] (2) Operation of the base station 200 The base station 200 sets either conventional MG or 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 content that is substantially the same as the description of the operation of the UE 100 will be omitted.

[0082] (2-1) Setting MG The base station 200 sets either a conventional MG or a P-MG. Specifically, the base station 200 (control unit 243) selectively sets either a conventional MG or a P-MG based on conditions. For example, the base station 200 selectively sets either a conventional MG or a P-MG 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.

[0083] 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.

[0084] Furthermore, if 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. Furthermore, if P-MG is not set, the base station 200 sets preconfiguredGap-r17 to "release."

[0085] (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.

[0086] For example, base station 200 transmits an RRC message including MG configuration information including common configuration information for the configured MG and configuration information of the P-MG to UE 100. For example, the RRC message including the MG configuration information may be an RRCReconfiguration message or an RRCResume message.

[0087] (3) Processing flow An example of processing according to the first embodiment of the present disclosure will be described with reference to FIGS.

[0088] First, with reference to FIG. 9, an example of a schematic flow of processing by the system 1 according to the first embodiment of the present disclosure will be described.

[0089] The base station 200 sets up an MG (S310). For example, the base station 200 sets up a P-MG. That is, common setting information and setting information for the P-MG are set up.

[0090] 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.

[0091] 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).

[0092] The UE 100 acquires the MG configuration information from the received RRC message (S340). For example, the UE 100 acquires measGapConfig as the MG configuration information from the received RRCReconfiguration message or RRCResume message.

[0093] 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.

[0094] Next, with reference to FIG. 10, an example of a schematic flow of MG configuration in the UE 100 according to the first embodiment of the present disclosure will be described.

[0095] The UE 100 determines whether or not the configuration information of the P-MG indicates release (S410). For example, the UE 100 determines whether preconfiguredGap-r17 included in GapConfig, which is set as a parameter value set to setup among gapUE, gapFR1, and gapFR2 in measGapConfig, is setup or release.

[0096] If the configuration information of the P-MG does not indicate "release", the UE 100 determines whether the configuration information of the P-MG indicates "activated" (S420). For example, if the preconfiguredGap-r17 is "setup", the UE 100 determines whether the preconfiguredGapState-r17 included in the PreconfiguredGapConfig-r17 set as the value of the preconfiguredGap-r17 is "activated" or "deactivated".

[0097] If the configuration information of the P-MG indicates activated, the UE 100 configures the MG in the activated state (S430). For example, if preconfiguredGapState-r17 is activated, the UE 100 configures the MG whose activation state is activated. In other words, the UE 100 operates as if the P-MG is activated.

[0098] If the configuration information of the P-MG does not indicate activated, the UE 100 configures the MG in a deactivated state (S440). If preconfiguredGapState-r17 is deactivated, the UE 100 configures the MG with an activation state of deactivated. In other words, the UE 100 operates as if the P-MG is deactivated.

[0099] If the configuration information of the P-MG indicates release, the UE 100 configures the conventional MG (S450). For example, if preconfiguredGap-r17 is release, the UE 100 configures the conventional MG. That is, PreconfiguredGapConfig-r17 is not configured. In this case, the MG configuration in measGapConfig continues to be applied until the measGapConfig is released, as in the conventional case.

[0100] The P-MG settings described above may be reflected in a TS. Information 25 in Fig. 11 is an example of how the P-MG settings are reflected in a TS. Naturally, the manner in which the P-MG settings are reflected in a TS is not limited to this.

[0101] (4) Effects As described above, according to the first embodiment of the present disclosure, an RRC message including MG configuration information is transmitted from a base station to a UE 100. The MG configuration information includes common configuration information used in the conventional MG and the P-MG, and P-MG configuration information indicating that the P-MG is configured. This allows the conventional MG and the P-MG to use the same MG configuration information, while distinguishing whether the MG configuration information is for the conventional MG or the P-MG. This makes it possible to avoid conflicts between the configurations of two coexisting MGs. Furthermore, by reusing the MG configuration information used in the conventional MG, the same MG configuration information can be used for both the conventional MG and the P-MG. In other words, it can be said that the configuration of the conventional MG can be transformed into the configuration of the P-MG, or vice versa.

[0102] Furthermore, if different and independent MG configuration information is used between the conventional MG and the P-MG, the definition of additional operations may be required to avoid a conflict between the configurations of the two MGs. For example, the network (i.e., the base station) must control the network so that the conventional MG is not configured when the P-MG is configured, and conversely, the P-MG is not configured when the conventional MG is configured. In contrast, according to the first embodiment of the present disclosure, it is possible to avoid a conflict between the configurations of two coexisting MGs without the above-mentioned additional operations.

[0103] <4-2. Modifications> First to third modified examples of the first embodiment of the present disclosure will be described below. Note that two or more of these modified examples may be combined.

[0104] (1) First Modification: Second Example of P-MG Setting Information In the first embodiment of the present disclosure described above, 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 first embodiment of the present disclosure is not limited to this example.

[0105] As a first modification of the first embodiment of the present disclosure, information separate from the setting information of the P-MG may indicate activation or deactivation of the P-MG.

[0106] Specifically, the P-MG setting information indicates whether the P-MG is set up, and the P-MG status information, which is separate from the P-MG setting information, indicates the activation or deactivation of the P-MG.

[0107] For example, referring to information 27 in FIG. 12, GapConfig includes parameters preconfiguredGap-r17 as P-MG configuration information and preconfiguredGapState-r17 as P-MG state information. preconfiguredGap-r17 indicates whether the P-MG is configured or not, and can take the value TRUE or FALSE. preconfiguredGapState-r17 indicates whether the P-MG is activated or deactivated. preconfiguredGapState-r17 is configured when preconfiguredGap-r17 is TRUE.

[0108] An example of the flow of processing according to this modified example will be described with reference to Fig. 10. Note that a description of processing that is substantially the same as the processing according to the first embodiment of the present disclosure described above will be omitted.

[0109] 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.

[0110] 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.

[0111] Instead of S430, if the P-MG state information indicates activated, the UE 100 sets the MG in the activated state.

[0112] Instead of S440, if the P-MG state information does not indicate activated, the UE 100 sets the MG to a deactivated state.

[0113] Instead of S450, if the configuration information of the P-MG indicates FALSE, the UE 100 configures the conventional MG.

[0114] 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. Naturally, the manner in which the P-MG settings are reflected in the TS is not limited to this.

[0115] As described above, according to the first modification of the first embodiment of the present disclosure, information separate from the configuration 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 P-MG configuration information being continuously retained in the UE 100. Furthermore, by separating the P-MG configuration information and the P-MG state information, it is possible to instruct the activation state of the P-MG to the UE 100 regardless of the configuration of the P-MG. For example, the activation state can be instructed in the RRC layer or the PHY layer, or can be changed by another trigger (for example, BWP switching based on a timer).

[0116] (2) Second Modification: Third Example of P-MG Setting Information In the first 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 first embodiment of the present disclosure is not limited to this example.

[0117] As a second modification of the first embodiment of the present disclosure, the P-MG setting information may indicate whether or not the P-MG is set depending on the presence or absence.

[0118] Specifically, if the P-MG is not configured, the P-MG setting information does not need to be included in the MG setting information. More specifically, the P-MG setting information may be information indicating the activation status. For example, of The configuration information may be preconfiguredGapState-r17 as shown in Fig. 8. preconfiguredGapState-r17 is included in GapConfig if P-MG is configured, and is not included in GapConfig if P-MG is not configured.

[0119] As described above, according to the second modification of the first embodiment of the present disclosure, if the P-MG is not configured, the P-MG configuration information is not included in the MG configuration information. This makes it possible to reduce the amount of communication traffic in signaling while indicating whether the P-MG is configured or not.

[0120] (3) Third Modification: Independent setting for conventional MG and P-MG In the first embodiment of the present disclosure described above, the MG setting information is shared between the conventional MG and the P-MG. However, the MG setting information according to the first embodiment of the present disclosure is not limited to this example.

[0121] As a third modification of the first embodiment of the present disclosure, the MG setting information may be defined separately for the conventional MG and the P-MG.

[0122] Specifically, the MG configuration information for the conventional MG and the MG configuration information for the P-MG may be included independently in the Measurement configuration information. For example, MeasConfig may include measGapConfig for the conventional MG and measGapConfig for the P-MG.

[0123] The MG setting information for the conventional MG is the conventional MG setting information. The MG setting information for the P-MG includes the P-MG setting information as described above in addition to the conventional MG setting information.

[0124] Note that the MG setting information for the P-MG may partially include the P-MG setting information 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, the 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.

[0125] The network (i.e., base station 200) configures only one MG during MG configuration, i.e., the base station 200 generates only either MG configuration information for a conventional MG or MG configuration information for a P-MG.

[0126] Alternatively, UE 100 may select one MG configuration information. For example, when MG configuration information for a conventional MG and MG configuration information for a P-MG are included in the Measurement configuration information, UE 100 may leave the MG configuration information for the P-MG and discard the conventional MG configuration information. Note that when only one of the MG configuration information for the conventional MG and the MG configuration information for the P-MG is included, the MG is configured based on the included MG configuration information.

[0127] As described above, according to the third modification of the first embodiment of the present disclosure, the MG setting information is defined separately for 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 that are used only for the P-MG or only for the conventional MG.

[0128] 5. Second Embodiment A second embodiment of the present disclosure will be described. In the second embodiment, when BWP switching occurs, the activation state of the MG is set according to the BWP after the switch. In addition, when a conventional MG and a P-MG coexist, the activation state of the P-MG is set according to the BWP after the switch.

[0129] <5-1. First operation example> A first operation example of the second embodiment of the present disclosure will be described below. In the first operation example, the activation state of the MG is set according to the requirement of the MG in the BWP after the switch.

[0130] (1) Operation of UE100 When BWP switching occurs, the UE 100 determines the necessity of an MG, and sets the activation state of the MG according to the necessity of the MG.

[0131] (1-1) BWP switching judgment The UE 100 determines whether or not BWP switching has occurred. Specifically, the UE 100 (control unit 133) determines whether or not BWP switching based on a timer has occurred.

[0132] More specifically, the UE 100 determines whether a timer related to BWP switching has expired. For example, the timer is a BWP inactivity timer.

[0133] When BWP switching occurs, the BWP switches to a predetermined BWP. For example, the predetermined BWP is a default DL (Downlink) BWP. If a default DL BWP is not set, the predetermined BWP may be an initial DL BWP. Note that the predetermined BWP may be a specific BWP other than the default DL BWP or the initial DL BWP.

[0134] (1-2) Determining the need for MG The UE 100 (control unit 133) determines whether MG is necessary in the BWP after switching. Specifically, the UE 100 determines whether MG is necessary based on conventional conditions for determining whether MG is necessary. For example, the UE 100 determines whether MG is necessary based on conditions for determining whether MG is necessary for measurement (i.e., whether it is gap-assisted or non-gap-assisted) described in 3GPP TS38.300. Furthermore, the necessity of MG is determined for a measurement method based on a predetermined control signal. In other words, the predetermined control signal is a signal used for measurement.

[0135] More specifically, the necessity of MG may be determined based on a report on the necessity of MG from UE 100 in the BWP after switching. For example, when the measurement method is SSB (Synchronization Signal Block)-based inter-frequency measurement or SSB-based intra-frequency measurement, UE 100 determines the necessity of MG depending on whether MG requirement information is reported to base station 200. When UE 100 reports MG requirement information, UE 100 determines that MG is required. For example, the report is the transmission of an RRC message such as RRCReconfigurationComp or RRCResumeComp including the MG requirement information.

[0136] Furthermore, the necessity of MG may be determined based on the capability of the UE 100 for the BWP after the switch. For example, when the measurement method is SSB-based inter-frequency measurement, the UE 100 determines the necessity of MG according to the type of MG that it supports for the BWP after the switch. When the UE 100 supports only per-UE MG, it determines that MG is required.

[0137] Furthermore, the necessity of MG may be determined based on the frequency for measurement in the serving cell in the BWP after the switch. For example, when the measurement method is SSB-based inter-frequency measurement, if UE 100 itself supports per-FR MG, UE 100 determines the necessity of MG depending on whether the frequency ranges for measurement in multiple serving cells are the same in the BWP after the switch. If the frequency ranges for measurement in multiple serving cells are the same, UE 100 determines that MG is required.

[0138] Furthermore, the necessity of MG may be determined based on the frequency resource of a predetermined control signal in the BWP after the switch. For example, when the measurement method is SSB-based intra-frequency measurement, the UE 100 determines the necessity of MG depending on whether the BWP after the switch includes the frequency resource of the SSB related to the initial DL BWP. If the BWP after the switch does not include the frequency resource of the SSB, the UE 100 determines that MG is required.

[0139] The measurement method may be a CSI-RS (Channel State Information Reference Signal) based inter-frequency measurement.

[0140] Also, only some of the conditions described in TS38.300 may be applied. Also, the conditions for determining whether MG is necessary are not limited to the conditions described in TS38.300, and may include other conditions.

[0141] (1-3) Setting the MG activation status The UE 100 sets the activation state of the MG according to the necessity of the MG. Specifically, the UE 100 (control unit 133) sets activation or deactivation of the MG according to the necessity of the MG in the BWP after the switch.

[0142] For example, if an MG is required in the BWP after the switch, the UE 100 activates the MG, i.e., the state is set to activation. If an MG is not required in the BWP after the switch, the UE 100 deactivates the MG, i.e., the state is set to deactivation.

[0143] (2) Operation of the base station 200 When BWP switching occurs, the base station 200 determines the necessity of MG. The base station 200 sets the activation state of the MG according to the necessity of MG. Note that detailed description of the contents that are substantially the same as the description of the operation of the UE 100 will be omitted.

[0144] (2-1) BWP switching judgment The base station 200 determines whether BWP switching has occurred. Specifically, the base station 200 (control unit 243) determines whether timer-based BWP switching has occurred. The determination of timer-based BWP switching is substantially the same as the operation of the UE 100, and therefore, description thereof will be omitted.

[0145] (2-2) Determining the need for MG Base station 200 determines whether MG is necessary in the BWP after switching. Specifically, base station 200 determines whether MG is necessary based on the conditions described in 3GPP TS38.300, similar to the operation of UE 100. The determination of whether MG is necessary is substantially the same as the operation of UE 100, except for the determination of whether MG is necessary based on a report from UE 100 about the necessity of MG, and therefore a description thereof will be omitted.

[0146] In determining the necessity of MG based on a report from the UE 100 about the necessity of MG, the base station 200 operates differently from the UE 100 in that the report is received from the UE 100 .

[0147] For example, base station 200 determines whether MG requirement information is required depending on whether MG requirement information is reported from UE 100. When MG requirement information is reported, base station 200 determines that MG is required. Note that base station 200 may request the UE 100 to report the MG requirement information. For example, base station 200 may transmit to UE 100 an RRC message such as RRCReconfiguration or RRCResume that includes information for causing UE 100 to report the MG requirement information.

[0148] (2-3) Setting the MG activation status The base station 200 sets the activation state of the MG according to the necessity of the MG. Specifically, the base station 200 (control unit 243) sets the activation or deactivation of the MG according to the necessity of the MG in the BWP after the switch. The setting of the activation state is substantially the same as the operation of the UE 100, and therefore a description thereof will be omitted.

[0149] (3) Processing flow An example of processing according to the first operation example of the second embodiment of the present disclosure will be described with reference to FIGS.

[0150] First, with reference to FIG. 14, an example of a schematic flow of processing by the system 1 according to the first operation example of the second embodiment of the present disclosure will be described.

[0151] The UE 100 and the base station 200 determine whether BWP switching has occurred based on the timer (S510). For example, the UE 100 and the base station 200 determine whether the time on the BWP switching timer has expired.

[0152] When BWP switching occurs, the UE 100 and the base station 200 determine whether MG is required in the BWP after switching (S520). For example, when the timer for BWP switching expires, the UE 100 and the base station 200 determine whether MG is required in the BWP after switching based on the conditions for requiring MG described in TS38.300. Details will be described later with reference to FIG. 15.

[0153] If an MG is required in the BWP after the switch, the UE 100 and the base station 200 set the MG in the activated state (S530). For example, if an MG is required in the BWP after the switch, the UE 100 and the base station 200 set an MG whose activation state is activated. In other words, the UE 100 and the base station 200 operate as if the MG is activated.

[0154] If the MG is not required in the BWP after the switch, the UE 100 and the base station 200 set the MG in a deactivated state (S540). For example, if the MG is not required in the BWP after the switch, the UE 100 and the base station 200 set the MG with an activation state of deactivated. In other words, the UE 100 and the base station 200 operate as if the MG is deactivated.

[0155] Next, with reference to FIG. 15, an example of a schematic flow of a process of determining the necessity of MG in the UE 100 and the base station 200 according to the first operation example of the second embodiment of the present disclosure will be described.

[0156] The UE 100 and the base station 200 determine whether or not the UE 100 reports the necessity of MG for the BWP after switching (S610). For example, the UE 100 determines whether or not to report MG requirement information to the base station 200. Furthermore, the base station 200 determines whether or not the MG requirement information has been reported from the UE 100.

[0157] Furthermore, the UE 100 and the base station 200 determine whether the capabilities of the UE 100 are adapted to the BWP after the switch (S620). For example, the UE 100 and the base station 200 determine whether the UE 100 supports only per-UE MG for the BWP after the switch. If the UE 100 supports only per-UE MG, it can be said that the UE 100 is not adapted to the BWP after the switch.

[0158] Furthermore, the UE 100 and the base station 200 determine whether or not the measurement frequencies in the plurality of serving cells are the same for the BWP after the switch (S630). For example, the UE 100 and the base station 200 determine whether or not the frequency ranges for measurement in the plurality of serving cells are the same for the BWP after the switch.

[0159] Furthermore, the UE 100 and the base station 200 determine whether or not the BWP after the switch includes a frequency resource of a predetermined control signal (S640). For example, the UE 100 and the base station 200 determine whether or not the BWP after the switch includes a frequency resource of an SSB related to the initial BWP.

[0160] S610 above or S If the determination in S630 is YES, or if the determination in S620 or S640 is NO, the process proceeds to S530, and the UE 100 and the base station 200 activate the MG since the MG is necessary.

[0161] If the determination in the above S640 is YES, the process proceeds to S540, and the UE 100 and the base station 200 deactivate the MG since the MG is not necessary.

[0162] The MG settings according to the first operation example described with reference to Figures 14 and 15 may be reflected in a TS. Information 35 in Figure 16 is an example of how the MG settings are reflected in a TS. Naturally, the manner in which the MG settings are reflected in a TS is not limited to this.

[0163] (4) Effects As described above, according to the first operation example of the second embodiment of the present disclosure, when switching of the BWP used for communication between the UE 100 and the base station 200 occurs, activation or deactivation of the MG is set according to the BWP after the switch. This allows the same activation state according to the BWP after the switch to be set in the UE 100 and the base station 200, respectively, without signaling between the UE 100 and the base station 200. Therefore, it is possible to suppress a decrease in signaling efficiency while aligning the activation states of the MG between the network and the UE.

[0164] According to the first operation example, activation or deactivation of the MG is set according to the necessity of the MG in the BWP after the switch. This allows the same activation state suitable for the BWP after the switch to be set in the UE 100 and the base station 200, respectively.

[0165] Furthermore, the necessity of an MG in the BWP after the switch is determined based on the determination conditions for the necessity of the first MG (conventional MG). For example, the necessity of an MG may be based on a report on the necessity of an MG from UE 100 in the BWP after the switch. Furthermore, the necessity of an MG may be based on the capability of UE 100 for the BWP after the switch. Furthermore, the necessity of an MG may be based on a frequency for measurement in the serving cell in the BWP after the switch. Furthermore, the necessity of an MG may be based on resources for a predetermined control signal in the BWP after the switch. Furthermore, the necessity of an MG may be about a measurement method based on a predetermined control signal. Furthermore, the predetermined control signal may be SSB or CSI-RS. This makes it possible to align the setting conditions for the activation state of an MG with the determination conditions for the necessity of a conventional MG.

[0166] Furthermore, BWP switching includes timer-based BWP switching. Here, in the case of timer-based BWP switching, the UE and the base station operate independently for BWP switching, i.e., they independently set the activation state of the MG. However, in this case, the activation state is not synchronized or notified between the UE and the base station, which may cause inconsistency in the activation state between the UE and the base station. On the other hand, synchronizing or notifying the activation state between the UE and the base station is undesirable because it requires additional signaling. In contrast, according to the second embodiment of the present disclosure, the activation state at the time of BWP switching is set between the UE 100 and the base station 200 using a common criterion, i.e., the necessity of MG. Therefore, even in the case of timer-based BWP switching, the activation state can be consistent between the UE 100 and the base station 200 without signaling for synchronization or notification of the activation state.

[0167] Furthermore, switching of a BWP includes switching to a specific BWP, and the specific BWP includes a default BWP or an initial BWP. By defining the operation for switching to a specific BWP, it is possible to prevent the setting of the activation state according to BWP switching from becoming complicated.

[0168] <5-3. Second operation example> Next, a second operation example of the second embodiment of the present disclosure will be described. In the second operation example, the activation state of the MG is set based on the setting of the activation state corresponding to the BWP after switching. Note that detailed description of the contents that are substantially the same as the description in the first operation example will be omitted.

[0169] (1) Operation of UE100 When BWP switching occurs, the UE 100 sets the activation state of the MG based on the setting of the activation state corresponding to the BWP switching.

[0170] (1-1) BWP switching judgment The UE 100 determines whether BWP switching has occurred. Specifically, the UE 100 (control unit 133) determines whether BWP switching based on a timer has occurred. The determination of BWP switching based on a timer is substantially the same as that in the first operation example, and therefore, a description thereof will be omitted.

[0171] (1-2) Setting the MG activation status When BWP switching occurs, the UE 100 sets the activation state of the MG. Specifically, the UE 100 (control unit 133) sets activation or deactivation of the MG based on the setting of the activation state corresponding to the BWP after switching.

[0172] More specifically, when BWP switching occurs, the UE 100 sets the activation or deactivation of the MG based on the default setting of the activation state corresponding to the BWP after switching, which default setting indicates the activation or deactivation of the MG.

[0173] For example, when the BWP is switched to the default DL BWP or the initial DL BWP, if the default setting indicates activation, the UE 100 activates the MG, i.e., the state is set to activation. If the default setting indicates deactivation, the UE 100 deactivates the MG, i.e., the state is set to deactivation.

[0174] Here, the activation state setting corresponding to the BWP after the switch is included in the MG configuration. Referring to information 43 in Figure 17, in preconfiguredGap-r17 as part of the MG configuration, PreconfiguredGapConfig-r17 is set in the case of setup, and PreconfiguredGapConfig-r17 includes defaultBWP-PreconfigurdGapState-r17 as the above default setting. defaultBWP-PreconfigurdGapState-r17 can take the value activated or deactivated.

[0175] Furthermore, the UE 100 (communication processing unit 135) receives an RRC message including MG configuration information indicating MG configuration including the setting of the activation state corresponding to the BWP after switching. Referring to information 43 in FIG. 17 , preconfiguredGap-r17 including defaultBWP-PreconfiguredGapState-r17 is included in GapConfig. MeasGapConfig as MG configuration information including GapConfig is an RRC Information Element and is included in the RRC message. The RRC message may be, for example, an RRCReconfiguration message or an RRCResume message.

[0176] In addition, the above switch rear The MG setting information including the setting of the activation status corresponding to the BWP may be the MG setting information according to the first embodiment, or may be the MG setting information for the P-MG according to the second variant of the first embodiment.

[0177] (2) Operation of the base station 200 When BWP switching occurs, base station 200 sets the activation state of MG based on the setting of the activation state corresponding to BWP switching. Note that detailed description of the content that is substantially the same as the description of the operation of UE 100 will be omitted.

[0178] (2-1) BWP switching judgment The base station 200 determines whether BWP switching has occurred. Specifically, the base station 200 (control unit 243) determines whether timer-based BWP switching has occurred. The determination of timer-based BWP switching is substantially the same as in the first operation example, and therefore description thereof will be omitted.

[0179] (2-2) Setting the MG activation status When BWP switching occurs, the base station 200 sets the activation state of the MG. Specifically, the base station 200 (control unit 243) sets the activation or deactivation of the MG based on the setting of the activation state corresponding to the BWP after switching. The setting of the activation state is substantially the same as the operation of the UE 100, so a description thereof will be omitted.

[0180] (3) Processing flow An example of processing according to the second operation example of the second embodiment of the present disclosure will be described with reference to Fig. 18. Note that detailed description of processing that is substantially the same as the processing according to the first operation example will be omitted.

[0181] The UE 100 and the base station 200 determine whether BWP switching has occurred based on the timer (S710).

[0182] When BWP switching occurs, the UE 100 and the base station 200 determine whether the setting of the MG state corresponding to the BWP switch is activated (S720). For example, when the timer for BWP switching expires, the UE 100 and the base station 200 determine whether the default setting of the activation state corresponding to the BWP after the switch is activated.

[0183] If the setting of the MG state corresponding to the BWP switch is activated, the UE 100 and the base station 200 set the MG to the activated state (S730). For example, if the default setting of the activation state corresponding to the BWP after the switch is activated, the UE 100 and the base station 200 set the MG to the activated state. In other words, the UE 100 and the base station 200 operate as if the MG is activated.

[0184] If the setting of the MG state corresponding to the BWP switch is not activated, the UE 100 and the base station 200 set the MG to the deactivated state (S740). For example, if the default setting of the activation state corresponding to the BWP after the switch is deactivated, the UE 100 and the base station 200 set the MG to the deactivated state. In other words, the UE 100 and the base station 200 operate as if the MG is deactivated.

[0185] The MG settings according to the second operation example described with reference to Fig. 18 may be reflected in the TS. Information 45 in Fig. 19 is an example of how the MG settings are reflected in the TS. Naturally, the manner in which the MG settings are reflected in the TS is not limited to this.

[0186] (4) Effects Thus, according to the second operation example of the second embodiment of the present disclosure, similar to the first operation example, it is possible to suppress a decrease in signaling efficiency while aligning the MG activation state between the network and the UE.

[0187] Furthermore, according to the second operation example, activation or deactivation of the MG is set based on the setting of the activation state corresponding to the BWP after switching. This allows the same activation state to be set in the UE 100 and the base station 200 at the time of BWP switching. Furthermore, the activation state at the time of BWP switching can be specified without relying on an existing TS.

[0188] In addition, the activation status setting corresponding to the BWP after the switch is included in the MG configuration, which allows information about the MG configuration to be consolidated and improves signaling efficiency.

[0189] Furthermore, an RRC message including MG setting information indicating an MG setting including a setting of an activation state corresponding to the BWP after the switch is transmitted from base station 200 to UE 100. This makes it possible to notify UE 100 of the setting of an activation state corresponding to the BWP after the switch by using the existing MG setting information.

[0190] The activation status setting indicates the activation or deactivation of the MG corresponding to the BWP after the switch. In this way, the setting value directly indicates the activation status, which simplifies the setting of the activation status.

[0191] <5-4. Variations> A first operation example and a modified example of the second operation example of the second embodiment of the present disclosure will be described.

[0192] (1) Variation: BWP switching based on DL control signal In the second embodiment of the present disclosure described above, the BWP switching is timer-based BWP switching. However, the BWP switching according to the second embodiment of the present disclosure is not limited to this example.

[0193] As a modification of the second embodiment of the present disclosure, the BWP switching may be BWP switching based on a DL control signal.

[0194] Specifically, the UE 100 (communication processing unit 135) receives a DL control signal. The UE 100 (control unit 133) determines whether or not the received DL control signal includes information indicating BWP switching.

[0195] For example, as shown in S510 of FIG. 14 or S710 of FIG. 18, the UE 100 determines whether or not DCI (Downlink Control Information) indicating BWP switching has been received on a PDCCH (Physical Downlink Control Channel).

[0196] As described above, according to the modification of the second embodiment of the present disclosure, the BWP switching includes BWP switching based on a DL control signal. Therefore, the BWP switching can be explicitly synchronized between the UE 100 and the base station 200. Therefore, the timing of setting the activation state can be more reliably synchronized without signaling for setting the activation state.

[0197] 6. Third Embodiment A third embodiment of the present disclosure will be described below. In the third embodiment, the activation state of MG sharing (i.e., the applicability or validity of MG sharing) is determined in conjunction with the activation state of MG.

[0198] <6-1. Example of operation> An example of the operation of the UE 100 and the base station 200 according to the third embodiment of the present disclosure will be described with reference to FIGS.

[0199] (1) Operation of UE100 The UE 100 receives MG sharing configuration information from the base station 200. The UE 100 determines whether to apply MG sharing to the MG based on the activation state of the MG. The operation of the UE 100 and related information will be described in detail below.

[0200] (1-1) Receive MG sharing setting information The UE 100 receives MG sharing setting information. Specifically, the UE 100 (communication processing unit 135) receives an RRC message including the MG sharing setting information from the base station 200. The UE 100 (information acquisition unit 131) acquires the MG sharing setting information included in the RRC message. For example, the MG sharing setting information is MeasGapSharingConfig, which is an RRC IE.

[0201] Furthermore, the UE 100 receives information indicating an activation state of the MG. Specifically, the UE 100 receives an RRC message including information indicating the activation state of the MG from the base station 200. The information indicating the activation state of the MG may be included in the MG configuration information.

[0202] Furthermore, an RRC message including MG sharing configuration information and MG configuration information may be transmitted from base station 200 to UE 100. For example, an RRC message including Measurement configuration information including MG sharing configuration information and MG configuration information is transmitted from base station 200 to UE 100. The RRC message may be an RRCReconfiguration message or an RRCResume message.

[0203] (1-2) Determine the activation status of MG The UE 100 determines the activation state of the MG. Specifically, the UE 100 (control unit 133) determines the activation state of the MG based on information indicating the activation state of the MG.

[0204] For example, the information indicating the activation state of the MG may be preconfiguredGapState-r17 as shown in Fig. 8 or Fig. 12. The information indicating the activation state of the MG indicates whether the MG is activated or deactivated.

[0205] The activation state of the MG is set or determined based on the process shown in FIG. 10 in the first embodiment or the process shown in FIG. 14 or FIG. 18 in the second embodiment.

[0206] (1-3) Determine the activation status of MG Sharing The UE 100 determines the activation status of MG sharing, where the activation or deactivation of MG sharing corresponds to the activation or deactivation of MG.

[0207] Specifically, the UE 100 (control unit 133) determines activation or deactivation of MG sharing based on the determination of the activation state of the MG.

[0208] More specifically, the UE 100 (control unit 133) determines the activation state of the MG based on information indicating the activation state of the MG.

[0209] For example, when the MG is set to activation, the UE 100 (control unit 133) determines that the MG sharing is activated. When the MG is set to deactivation, the UE 100 (control unit 133) determines that the MG sharing is deactivated.

[0210] If it is determined that MG sharing is to be activated, the MG sharing settings are applied to the MG. In other words, the MG sharing settings are enabled. If it is determined that MG sharing is to be deactivated, the MG sharing settings are not applied to the MG. In other words, the MG sharing settings are disabled. Note that even if it is determined that MG sharing is to be deactivated, the MG sharing settings are not discarded.

[0211] (2) Operation of the base station 200 The base station 200 configures the MG and MG sharing, and transmits the MG configuration information and the MG sharing configuration information to the UE 100. The base station 200 determines whether to apply MG sharing to the MG based on the activation state of the MG. The operation of the base station 200 and related information will be described in detail below. Note that detailed description of the contents that are substantially the same as the description of the operation of the UE 100 will be omitted.

[0212] (2-1) Send MG sharing setting information The base station 200 transmits MG sharing setting information to the UE 100. Specifically, the base station 200 (information acquisition unit 241) acquires the MG sharing setting information. The base station 200 (communication processing unit 245) transmits an RRC message including the acquired MG sharing setting information to the UE 100. For example, the base station 200 sets MG sharing, thereby acquiring MG sharing setting information indicating the setting of the MG sharing.

[0213] Furthermore, base station 200 transmits information indicating the activation state of the MG to UE 100. Specifically, base station 200 transmits an RRC message including information indicating the activation state of the MG to UE 100. For example, base station 200 acquires information indicating the activation state of the MG by also setting the activation state of the MG when setting the MG.

[0214] (2-2) Determine the activation status of MG The base station 200 determines the activation state of the MG. Specifically, the base station 200 (control unit 243) determines the activation state of the MG based on information indicating the activation state of the MG. The determination of the activation state of the MG is substantially the same as the operation of the UE 100, and therefore, a description thereof will be omitted.

[0215] (2-3) Determine the activation status of MG Sharing The base station 200 determines the activation state of MG sharing. Specifically, the base station 200 (control unit 243) determines the activation or deactivation of MG sharing based on the determination of the activation state of MG. The determination of the activation state of MG sharing is substantially the same as the operation of the UE 100, and therefore, description thereof will be omitted.

[0216] (3) Processing flow An example of processing according to the third embodiment of the present disclosure will be described with reference to FIGS.

[0217] First, with reference to FIG. 20, an example of a schematic flow of processing by the system 1 according to the third embodiment of the present disclosure will be described.

[0218] The base station 200 sets up an MG and MG sharing (S810). For example, the base station 200 sets up an MG and MG sharing, and generates MG setting information and MG sharing setting information.

[0219] The base station 200 transmits an RRC message including MG setting information and MG sharing setting information to the UE 100 (S820). For example, the base station 200 transmits an RRCReconfiguration message or an RRCResume message including measGapConfig and measGapSharingConfig to the UE 100. The measGapConfig includes preconfiguredGapState-r17 as information indicating the activation state of the MG.

[0220] The UE 100 transmits a response message to the received RRC message to the base station 200 (S830). For example, when the UE 100 receives an RRCReconfiguration message or an RRCResume message including measGapConfig and measGapSharingConfig from the base station 200, the UE 100 transmits an RRCReconfigurationComp message or an RRCResumeComp message to the base station 200.

[0221] The UE 100 acquires MG configuration information and MG sharing configuration information from the received RRC message (S840). For example, the UE 100 acquires measGapConfig and measGapSharingConfig from the received RRCReconfiguration message or RRCResume message.

[0222] The UE 100 and the base station 200 determine the activation state of MG sharing (S850). For example, the UE 100 and the base station 200 determine the activation state of MG sharing based on information indicating the activation state of MG. Details of the processing of S850 will be described later with reference to FIG. 21.

[0223] Next, with reference to FIG. 21, an example of a schematic flow of a process of determining the activation state of MG sharing in the UE 100 and the base station 200 according to the third embodiment of the present disclosure will be described.

[0224] The UE 100 and the base station 200 determine whether the MG is activated (S910). For example, the UE 100 and the base station 200 determine whether the MG is activated based on information indicating the activation state of the MG.

[0225] If the MG is activated, the UE 100 and the base station 200 determine whether MG sharing is set (S920). For example, if the information indicating the MG activation state indicates activation, the UE 100 determines whether MG sharing setting information has been received from the base station 200. The base station 200 determines whether MG sharing has been set.

[0226] If MG sharing is set, the UE 100 and the base station 200 determine that MG sharing is activated (S930). For example, if MG sharing is set, the UE 100 and the base station 200 determine that MG sharing is activated. In other words, the UE 100 and the base station 200 operate as if MG sharing is activated.

[0227] If the MG is not activated, the UE 100 and the base station 200 determine whether MG sharing is set (S940).

[0228] If MG sharing is configured, the UE 100 and the base station 200 determine that MG sharing is deactivated (S950). For example, if MG sharing is configured, the UE 100 and the base station 200 determine that MG sharing is deactivated. In other words, the UE 100 and the base station 200 operate as if MG sharing is deactivated.

[0229] The determination of the activation status of MG sharing described with reference to Fig. 21 may be reflected in the TS. Information 51 in Fig. 22 and information 53 in Fig. 23 are examples of reflecting the determination of the activation status of MG sharing in the TS. Naturally, the manner in which the determination of the activation status of MG sharing is reflected in the TS is not limited to this.

[0230] (4) Effects As described above, according to the third embodiment of the present disclosure, an RRC message including MG sharing configuration information is transmitted from the base station 200 to the UE 100, and activation or deactivation of MG sharing corresponds to activation or deactivation of an MG. This makes it possible to determine whether MG sharing is applied depending on the activation state of the MG. Therefore, it becomes possible to apply MG sharing to MGs that can be in the activated or deactivated state.

[0231] Furthermore, activation or deactivation of MG sharing is determined based on the determination of the activation state of MG. This allows each of UE 100 and base station 200, which can grasp the activation state of MG, to determine the activation state of MG sharing.

[0232] Furthermore, the activation status of the MG is determined based on information indicating the activation status of the MG, which allows the activation status of the MG sharing to more reliably correspond to the activation status of the MG.

[0233] Furthermore, an RRC message including information indicating the activation state of the MG is transmitted from the base station 200 to the UE 100. This allows the activation states of the MG to be synchronized between the UE 100 and the base station 200, and therefore the activation states of the MG sharing to be synchronized as well.

[0234] Furthermore, information indicating the activation state of the MG is included in the MG setting information, and an RRC message including the MG setting information and the MG sharing setting information is transmitted from base station 200 to UE 100. As a result, the information indicating the activation state of the MG and the MG sharing setting information are transmitted in the same RRC message, which can reduce the possibility of inconsistency occurring between the activation state of the MG and the activation state of MG sharing.

[0235] In addition, when MG is set to activation, MG sharing is determined to be activated, and when MG is set to deactivation, MG sharing is determined to be deactivated, so that the activation states of MG and MG sharing can be matched.

[0236] Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to these embodiments. It will be understood by those skilled in the art that these embodiments are merely examples and that various modifications are possible without departing from the scope and spirit of the present disclosure.
