- the UE 100 receives MG setting information from the base station 200 .
- UE 100 (communication processing unit 135 ) receives an RRC message including MG setting information from base station 200 .
- UE 100 (information acquisition unit 131) acquires the MG setting information included in the RRC message.
- MG setting information includes common setting information used in conventional MG (first MG) and P-MG (second MG), and P-MG setting information indicating that P-MG is set. .
- the P-MG configuration information indicates activation or deactivation of the P-MG when the P-MG is configured.
- the P-MG setting information indicates that the P-MG is not set when the P-MG is not set.
- the MG setting information is MeasGapConfig, which is an RRC IE (Information Element).
- the common setting information includes at least one parameter included in GapConfig set in MeasGapConfig.
- P-MG setting information is included in GapConfig.
- MeasGapConfig indicates whether MG is configured and can take values of setup or release.
- MeasGapConfig includes parameters such as gapUE, gapFR1, and gapFR2.
- This parameter is a setting presence/absence parameter indicating whether or not the MG is set for the unit in which the MG is set, and can take a value of setup or release.
- gapUE is setup
- MG is set for each UE (per UE)
- gapFR1 and gapFR2 are setup
- MG is set for each FR (per frequency range).
- the setting presence/absence parameter is setup, the IE GapConfig is set as the value.
- the MG configuration parameters for each unit are contained in GapConfig.
- GapConfig includes parameters such as gapOffset, mgl, mgrp, mgta, refServCellIndicator, refFR2ServCellAsyncCA-r16 and mgl-r16 as common setting information.
- gapOffset indicates the offset of the gap pattern with MGRP (Measurement Gap Repetition Period).
- mgl and mgl-r16 indicate the length of MG, that is, MGP (Measurement Gap Length).
- mgrp indicates the MG repetition period, ie, 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 for MG calculation.
- the above parameters as common configuration information can be used in both conventional MG and P-MG. Note that the common setting information may be at least one of the above parameters.
- GapConfig includes preconfiguredGap-r17 as P-MG setting information.
- preconfiguredGap-r17 indicates whether the P-MG is configured and can take the values setup or release. If preconfiguredGap-r17 is setup, P-MG is set. In other words, the MG is preconfigured. In this case, the IE PreconfiguredGapConfig-r17 is set as the value.
- PreconfiguredGapConfig-r17 contains preconfiguredGapState-r17. preconfiguredGapState-r17 indicates whether the P-MG is activated or deactivated. PreconfiguredGap-r17 as the setting information of the P-MG is optional.
- P-MG setting information indicates activation or deactivation of P-MG.
- information indicating activation or deactivation of the P-MG can be included in the MG setting information only when the P-MG is set. Therefore, it is possible to improve the efficiency of signaling. Also, by managing the activation or deactivation of MG as a state, it is possible to control whether or not to apply MG without discarding the MG settings.
- the P-MG setting information indicates that the P-MG is not set. This can clearly indicate that the P-MG is not set. Also, it is possible to specify whether the applied MG is a conventional MG or a P-MG. Therefore, inconsistency of MG setting information between the UE 100 and the base station 200 can be suppressed.
- the MG setting information is MeasGapConfig
- the common setting information includes at least one parameter included in GapConfig set in MeasGapConfig
- the P-MG setting information is included in GapConfig.
- An RRC message containing MG configuration information may be an RRCReconfiguration message or a RRCResume message.
- MG configuration information including P-MG configuration information can be transmitted from the base station 200 to the UE 100 using existing signaling between the UE and the base station. Therefore, addition of new signaling can be prevented.
- the RRC message including the MG configuration information including the P-MG configuration information is an additionally defined RRC message, which is an RRC message for transmitting the MG configuration information including the P-MG configuration information. There may be.
- MG configuration information including P-MG configuration information can be transmitted to UE 100 without changing existing RRC messages.
- the UE 100 sets the MG based on the MG setting information. Specifically, UE 100 (control unit 133 ) sets conventional MG or P-MG based on MG setting information included in the RRC message received from base station 200 .
- the UE 100 sets the P-MG when the P-MG setting information included in the MG setting information indicates that the P-MG is set. Also, the UE 100 sets the conventional MG when the P-MG setting information indicates that the P-MG is not set.
- UE 100 sets P-MG when preconfiguredGap-r17 included in Gapconfig shown in FIG. 8 is setup. That is, PreconfiguredGapConfig-r17 is set, which includes preconfiguredGapState-r17 set to activation or deactivation as a parameter.
- the UE 100 sets the conventional MG. Therefore PreconfiguredGapConfig-r17 is not set. That is, the P-MG mechanism is not applied to MG. Therefore, MG is not controlled using the state of activation. In other words, it can be said that MG is always in an activated state. Thus, when the P-MG setting information indicates that the P-MG is not set, the conventional MG is set, thereby maintaining compatibility with the conventional MG.
- Base station 200 sets either conventional MG or P-MG.
- the base station 200 transmits MG configuration information including common configuration information and P-MG configuration information to the UE 100 .

Alternatively, the information indicating the activation state of the P-MG may be included directly under the measurement configuration information without being included in the MG configuration information. For example, preconfiguredGapState-r17 shown in FIG. 8 may be included in parallel with measGapConfig directly under MeasConfig.

For example, when the measurement method is SSB-based inter-frequency measurement, UE 100 has the same frequency range for measurement in multiple serving cells in BWP after switching when it supports per-FR MG. The necessity of MG is determined according to whether or not. UE 100 determines that MG is required when the frequency range for measurement in multiple serving cells is the same.

本開示の第1の実施形態について説明する。第1の実施形態では、P-MGについてのMG設定情報は、従来のMGについてのMG設定情報を共有的に利用する。
図7~図10を参照して、本開示の第1の実施形態に係るUE100及び基地局200の動作の例を説明する。
UE100は、MG設定情報を基地局200から受信する。UE100は、受信したMG設定情報に含まれる共通設定情報及びP-MGの設定情報に基づきMGを設定する。以下、UE100の動作及び関係する情報について詳細に説明する。
UE100は、MG設定情報を基地局200から受信する。具体的にはUE100(通信処理部135)は、MG設定情報を含むRRCメッセージを基地局200から受信する。UE100(情報取得部131)は、当該RRCメッセージに含まれるMG設定情報を取得する。
UE100は、MG設定情報に基づきMGを設定する。具体的には、UE100(制御部133)は、基地局200から受信されるRRCメッセージに含まれるMG設定情報に基づき従来のMG又はP-MGを設定する。
基地局200は、従来のMG及びP-MGのいずれかを設定する。基地局200は、共通設定情報及びP-MGの設定情報を含むMG設定情報をUE100へ送信する。以下、基地局200の動作及び関係する情報について詳細に説明する。なお、UE100の動作における説明と実質的に同一である内容については詳細な説明を省略する。
基地局200は、従来のMG及びP-MGのいずれかを設定する。具体的には、基地局200(制御部243)は、条件に基づき従来のMG又はP-MGを選択的に設定する。例えば、UE100からのMGの設定要求の有無、又はUE100のP-MGに対する適応性若しくは能力などに基づき従来のMG又はP-MGが選択的に設定される。
基地局200は、MG設定情報をUE100へ送信する。具体的には、基地局200(情報取得部241)は、MG設定情報を取得する。基地局200(通信処理部245)は、取得されたMG設定情報を含むRRCメッセージをUE100へ送信する。
図9及び図10を参照して、本開示の第1の実施形態に係る処理の例を説明する。
このように、本開示の第1の実施形態によれば、MG設定情報を含むRRCメッセージが基地局からUE100へ送信され、MG設定情報は、従来のMG及びP-MGにおいて用いられる共通設定情報、及びP-MGが設定されることを示すP-MGの設定情報を含む。これにより、従来のMGとP-MGとの間で同一のMG設定情報を用いながら、当該MG設定情報が従来のMG向けであるかP-MG向けであるかを区別することができる。したがって、併存する2つのMGの設定のコンフリクトを回避することが可能になる。また、従来のMGで用いられるMG設定情報を流用することにより、同一のMG設定情報を従来のMG向け及びP-MG向けにそれぞれ使い分けることができる。換言すると、従来のMGの設定をP-MGの設定へ、又はP-MGの設定から従来のMGの設定へtransformすることができるとも言える。
本開示の第1の実施形態に係る第1~第3の変形例を説明する。なお、これらの変形例のうちの2つ以上が組み合わせられてもよい。
上述した本開示の第1の実施形態では、P-MGの設定情報は、P-MGが設定される場合、P-MGのアクティベーション又はディアクティベーションを示す。しかし、本開示の第1の実施形態に係るP-MGの設定情報は、この例に限定されない。
上述した本開示の第1の実施形態では、P-MGの設定情報は、P-MGが設定されるか否かを示す。しかし、本開示の第1の実施形態に係るP-MGの設定情報は、この例に限定されない。
上述した本開示の第1の実施形態では、MG設定情報は、従来のMGとP-MGとの間で共有される。しかし、本開示の第1の実施形態に係るMG設定情報は、この例に限定されない。
本開示の第2の実施形態について説明する。第2の実施形態では、BWPのスイッチング発生時に、スイッチ後のBWPに応じてMGのアクティベーションの状態が設定される。なお、従来のMGとP-MGとが併存する場合は、スイッチ後のBWPに応じてP-MGのアクティベーションの状態が設定される。
本開示の第2の実施形態の第1の動作例について説明する。第1の動作例では、スイッチ後のBWPにおけるMGの必要性(requirement)に応じてMGのアクティベーションの状態が設定される。
UE100は、BWPスイッチングが発生すると、MGの必要性を判定する。UE100は、MGの必要性に応じてMGのアクティベーションの状態を設定する。
UE100は、BWPのスイッチングが発生したか否かを判定する。具体的には、UE100(制御部133)は、タイマに基づくBWPスイッチングが発生したか否かを判定する。
UE100(制御部133)は、スイッチ後のBWPにおけるMGの必要性を判定する。具体的には、UE100は、従来のMGの必要性の判定条件に基づきMGの必要性を判定する。例えば、UE100は、3GPP TS38.300に記載されているMeasurementにMGを要するか否か(即ちgap-assistedであるかnon-gap-assistedであるか)を決める条件に基づきMGの必要性を判定する。また、MGの必要性は、所定の制御信号に基づくMeasurementの方式について判定される。換言すると、所定の制御信号は、Measurementに用いられる信号である。

基地局200は、スイッチ後のBWPにおけるMGの必要性を判定する。具体的には、基地局200は、UE100の動作と同様に、3GPP TS38.300に記載されている条件に基づきMGの必要性を判定する。MGの必要性の判定は、UE100からのMGの必要性についてのレポートに基づくMGの必要性の判定以外はUE100の動作と実質的に同一であるため、説明を省略する。
基地局200は、MGの必要性に応じてMGのアクティベーションの状態を設定する。具体的には、基地局200(制御部243)は、スイッチ後のBWPにおけるMGの必要性に応じて、MGのアクティベーション又はディアクティベーションを設定する。アクティベーションの状態の設定は、UE100の動作と実質的に同一であるため、説明を省略する。
図14及び図15を参照して、本開示の第2の実施形態の第1の動作例に係る処理の例を説明する。
このように、本開示の第2の実施形態の第1の動作例によれば、UE100と基地局200との通信に用いられるBWPのスイッチングが発生した場合、スイッチ後のBWPに応じてMGのアクティベーション又はディアクティベーションが設定される。これにより、UE100及び基地局200の間のシグナリングなしで、スイッチ後のBWPに応じた同一のアクティベーションの状態がUE100及び基地局200においてそれぞれ設定され得る。したがって、ネットワークとUEとの間のMGのアクティベーションの状態を整合させながら、シグナリングの効率の低下を抑制することが可能となる。
続いて、本開示の第2の実施形態の第2の動作例について説明する。第2の動作例では、スイッチ後のBWPに対応するアクティベーションの状態の設定に基づき、MGのアクティベーションの状態が設定される。なお、第1の動作例における説明と実質的に同一である内容については詳細な説明を省略する。

UE100は、BWPのスイッチングが発生したか否かを判定する。具体的には、UE100(制御部133)は、タイマに基づくBWPスイッチングが発生したか否かを判定する。タイマに基づくBWPスイッチングの判定は、第1の動作例と実質的に同一であるため、説明を省略する。
UE100は、BWPスイッチングが発生すると、MGのアクティベーションの状態を設定する。具体的には、UE100(制御部133)は、スイッチ後のBWPに対応するアクティベーションの状態の設定に基づき、MGのアクティベーション又はディアクティベーションを設定する。

図18を参照して、本開示の第2の実施形態の第2の動作例に係る処理の例を説明する。なお、第1の動作例に係る処理と実質的に同一である処理については詳細な説明を省略する。
このように、本開示の第2の実施形態の第2の動作例によれば、第1の動作例と同様に、ネットワークとUEとの間のMGのアクティベーションの状態を整合させながら、シグナリングの効率の低下を抑制することが可能となる。
本開示の第2の実施形態の第1の動作例及び第2の動作例に係る変形例を説明する。
上述した本開示の第2の実施形態では、BWPスイッチングは、タイマに基づくBWPスイッチングである。しかし、本開示の第2の実施形態に係るBWPスイッチングは、この例に限定されない。
本開示の第3の実施形態について説明する。第3の実施形態では、MGのアクティベーションの状態に連動してMGシェアリングのアクティベーションの状態(即ち、MGシェアリングの適用性又は有効性)が判定される。
