摘要： A method by a user equipment (UE) is described. The method includes receiving a first physical signal, determining a first physical structure based on information in the first physical signal, and determining resource elements based on the first physical structure. A first set of subcarriers with first subcarrier spacing which is integer multiple or integer sub-multiple of second subcarrier spacing are mapped such that in addition to a slot boundary one or more of starting positions or ending positions of first subcarriers with the first subcarrier spacing in a first set of OFDM symbols are aligned with one or more of starting positions or ending positions of second subcarriers with the second subcarrier spacing in a second set of OFDM symbols.

摘要： Provided is a technology related to a terminal device, a base station device, a communication system, a measurement method and an integrated circuit that efficiently perform cell measurement. The base station device configures a primary cell and one or more secondary cells to the terminal device, and indicates a measurement object, a reporting configuration including information indicating a threshold associated with an RSSI report and a report interval, and a measurement identity for linking the reporting configuration and the measurement object, to the terminal device. When, in each configured measurement identity, an associated reporting configuration includes information indicating the threshold associated with the RSSI report and the report interval, the terminal device periodically reports an average value of RSSIs measured in a duration of the report interval, and a percentage of the RSSIs being beyond the threshold as a measurement result.

摘要： A terminal apparatus receives a first configuration and a second configuration that are applied to a second cell group and first information. The terminal apparatus performs reconfiguration using the first configuration in a case of receiving a first value as the first information. The terminal apparatus performs reconfiguration using the second configuration in a case of receiving a second value as the first information. The terminal apparatus does not reset MAC and reestablishes RLC in the second cell group in a case of performing reconfiguration based on the first information.

摘要： A terminal apparatus determines whether information (first information) indicating whether a state of a secondary cell group is to be changed based on scg-State is included in the RRC signaling, in a case that the first information is not included in the RRC signaling, the state of the secondary cell group is changed based on whether the scg-State is included in the RRC signaling, and in a case that the first information is included in the RRC signaling, the state of the secondary cell group is not changed based on whether the scg-State is included in the RRC signaling.

摘要： Provided is a terminal apparatus for communicating with a base station apparatus. The terminal apparatus includes a receiver configured to receive an RRC message including configuration information of a multicast broadcast service (MBS) from the base station apparatus, and a processing unit. The configuration information of the MBS includes MBS session information. The MBS session information includes PDU session information. The processing unit releases a radio bearer for the MBS used for reception of the MBS session, based on stop of the reception of the MBS session by the terminal apparatus, and performs processing of notifying a higher layer of a part or all of the MBS session information.

摘要： A technology related to a terminal apparatus, a communication method, and an integrated circuit is provided for efficiently monitoring a status of communication. The terminal apparatus communicates with a base station apparatus by switching between a first frequency and a second frequency in the cell, in which any one of the first frequency and the second frequency is a frequency by which the terminal apparatus has established Radio Resource Control (RRC) connection, and a timer stops or continues based on first information in the case of switching between the first frequency and the second frequency.
