Terminal apparatus, base station apparatus, communication method, and integrated circuit
A terminal apparatus receives a first measurement configuration from a first base station apparatus via a first SRB and receives a second measurement configuration from a second base station apparatus via a second SRB, and transmits via the first SRB a first measurement result for the first measurement configuration configured from the first base station apparatus via the first SRB and transmits via the second SRB a second measurement result for the second measurement configuration configured from the second base station apparatus via the second SRB.
1. A terminal apparatus comprising:
reception circuitry configured to receive a first measurement configuration and a second measurement configuration; and
control circuitry configured to perform a measurement based on the first measurement configuration or the second measurement configuration, wherein
one or more cells of a master cell group and one or more cells of a secondary cell group are configured as serving cells of a dual connectivity,
the first measurement configuration of a measurement event to compare a measurement result of a serving cell of the master cell group with a first threshold is configured by an EUTRA RRC message,
the second measurement configuration of a measurement event to compare a measurement result of a serving cell of the secondary cell group with a second threshold is configured by an NR RRC message, and
the first measurement configuration of a measurement event to compare a measurement result of a serving cell of the master cell group with a third threshold and compare a measurement result of an NR neighbour cell with a fourth threshold is configured by an EUTRA RRC message.
2. The terminal apparatus according to claim 1 , wherein
the serving cell of the secondary cell group is considered as the NR neighbour cell in a case that the measurement result of the NR neighbour cell is compared with the forth fourth threshold.
3. A communication method for a terminal apparatus, the communication method comprising:
