Terminal equipment, base station equipment, and method

Abstract

To efficiently control communication.SOLUTION: A terminal apparatus determines whether to delete all entries included in an entry list held by the terminal apparatus in a case that an RRC connection reconfiguration is performed, deletes all entries included in the entry list in a case that it is determined to delete all entries included in the entry list, and does not delete one or more entries included in the entry list in a case that it is determined not to delete all entries included in the entry list.SELECTED DRAWING: Figure 9

Claims

1. A terminal device that communicates with a base station device, A receiving unit that receives a first RRC signaling from the base station device, which includes information regarding conditional resetting, It comprises a processing unit that holds an entry list, The information regarding the aforementioned conditional reset includes a list of additional modifications to the entries. The aforementioned list of additional modifications to entries includes one or more entries, Each entry contains at least one conditional reset information element. The aforementioned entry list includes one or more entries, The processing unit, based on the entry addition / modification list, adds one or more entries included in the entry addition / modification list to the entry list, or modifies one or more entries included in the entry list. The processing unit reconfigures the RRC connection based on the conditional reconfiguration information element included in the entry list or the received second RRC signaling. When the processing unit resets the RRC connection, if a synchronized reset information element is included in the entry list, or in the second RRC signaling, it determines, based on the first information included in the entry list, that one or more entries in the entry list should not be deleted, and determines to delete all entries in the entry list except for the one or more entries that were determined not to be deleted. Terminal device.

2. A base station device that communicates with terminal devices, A processing unit that generates a first RRC signaling that includes information regarding conditional resetting, The system includes a transmitting unit that transmits the first RRC signaling and the second RRC signaling, including the information regarding the conditional reset, to the terminal device. The processing unit causes the terminal device to add one or more entries included in the entry addition / modification list to the entry list, or to modify one or more entries included in the entry list, based on the entry addition / modification list. When the processing unit causes the terminal device to reset the RRC connection, if a synchronized reset information element is included in the entry list, or in the second RRC signaling, the processing unit causes the terminal device to decide not to delete one or more entries included in the entry list based on the first information included in the entry list, and to decide to delete all entries included in the entry list except for the one or more entries that were determined not to be deleted. Base station equipment.

3. A method for a terminal device to communicate with a base station device, The base station device receives a first RRC signaling that includes information regarding conditional reconfiguration. The information regarding the aforementioned conditional reset includes a list of additional modifications to the entries. The aforementioned list of additional modifications to entries includes one or more entries, Each entry contains at least one conditional reset information element. Maintain the entry list, The aforementioned entry list includes one or more entries, Based on the conditional reconfiguration information elements included in the entry list or the received second RRC signaling, the RRC connection is reconfigured. When resetting the RRC connection, if a synchronized reset information element is included in the conditional reset element or the second RRC signaling included in the entry list, it is determined not to delete one or more entries included in the entry list based on the first information included in the entry list, and it is determined to delete all entries included in the entry list except for the one or more entries that were determined not to be deleted. Based on the aforementioned list of additions and modifications to entries, one or more entries included in the aforementioned list of additions and modifications to entries are added to the aforementioned list of entries, or one or more entries included in the aforementioned list of entries are modified. method.
