Abstract
A terminal apparatus for communicating with a base station apparatus by using a second cell group including a PSCell considers a measurement object including first information as a first measurement object group, considers a measurement object not including the first information as a second measurement object group, and based on the second cell group being in a deactivated state, does not measure the first measurement object group or measures the first measurement object group in accordance with a relaxed requirement.
Claims3
A terminal apparatus for communicating with one or more base station apparatuses by using a master cell group (MCG) including a primary cell (PCell), and a secondary cell group (SCG) including a primary SCG cell (PSCell), the terminal apparatus comprising:
- a receiver configured to receive a radio resource control (RRC) message from the one or more base station apparatuses;
- and
- processing circuitry configured to:
- process the RRC message received from the one or more base station-apparatus apparatuses,
- configure a first active downlink bandwidth part (BWP) based on a BWP identifier included in the RRC message, and
- in a case that information, indicating that a cell group is to be deactivated, is included in the RRC message:
- deactivate the SCG,
- switch an active downlink BWP of the PSCell to the first active downlink BWP, and
- perform radio link monitoring by using a reference signal for the radio link monitoring configured for the first active downlink BWP.
A base station apparatus for communicating with a terminal apparatus by using a master cell group (MCG) including a primary cell (PCell), and a secondary cell group (SCG) including a primary SCG cell (PSCell), the base station apparatus comprising:
- processing circuitry configured to generate a radio resource control (RRC) message to be transmitted to the terminal apparatus;
- and
- a transmitter configured to transmit the RRC message to the terminal apparatus, wherein
- the terminal apparatus, after receiving the RRC message:
- configures a first active downlink bandwidth part (BWP) based on a BWP identifier included in the RRC message, and in a case that information indicating that a cell group is to be deactivated is included in the RRC message:
- deactivates the SCG,
- switches an active downlink BWP of the PSCell to the first active downlink BWP, and
- performs radio link monitoring by using a reference signal for the radio link monitoring configured for the first active downlink BWP.
A method performed by a terminal apparatus for communicating with one or more base station apparatuses by using a master cell group (MCG) including a primary cell (PCell), and a secondary cell group (SCG) including a primary SCG cell (PSCell), the method comprising:
- receiving a radio resource control (RRC) message from the one or more base station apparatuses;
- configuring a first active downlink bandwidth part (BWP) based on a BWP identifier included in the RRC message;
- and
- in a case that information indicating that a cell group is to be deactivated is included in the RRC message:
- deactivating the SCG,
- switching an active downlink BWP of the PSCell to the first active downlink BWP, and
- performing radio link monitoring by using a reference signal for the radio link monitoring configured for the first active downlink BWP.
