Terminal apparatus, base station apparatus, and method
View Patent ↗A terminal apparatus for communicating with a base station apparatus, the terminal apparatus including: a receiver configured to receive, from the base station apparatus, a Radio Resource Control (RRC) reconfiguration message including a radio bearer configuration information element; and a processing unit configured to, in a case that a radio bearer identity included in the radio bearer configuration information element is not part of a configuration of the terminal apparatus and that the radio bearer configuration information element includes a Service Data Adaptation Protocol (SDAP) configuration information element and that a Protocol Data Unit (PDU) session information element included in the SDAP configuration information element is not part of the configuration of the terminal apparatus, indicate to upper layers that a user-plane resource is configured for a PDU session corresponding to a value of the PDU session information element.
1. A terminal apparatus for communicating with a base station apparatus, the terminal apparatus comprising:
reception circuitry configured to receive, from the base station apparatus, a Radio Resource Control (RRC) reconfiguration message including a radio bearer configuration information element; and
processing circuitry configured to, based on a case that a radio bearer identity included in the radio bearer configuration information element is not part of a configuration of the terminal apparatus and that the radio bearer configuration information element includes a Service Data Adaptation Protocol (SDAP) configuration information element and that a value of a Protocol Data Unit (PDU) session information element included in the SDAP configuration information element is not part of the configuration of the terminal apparatus, indicate to upper layers that a user-plane resource is configured for a PDU session corresponding to the value of the PDU session information element.
2. The terminal apparatus according to claim 1 , wherein
the configuration of the user-plane resource includes a configuration related to a radio bearer.
3. A base station apparatus for communicating with a terminal apparatus, the base station apparatus comprising:
transmission circuitry configured to transmit a Radio Resource Control (RRC) reconfiguration message to the terminal apparatus; and
processing circuitry configured to include a radio bearer configuration information element in the RRC reconfiguration message to cause the terminal apparatus to perform processing, wherein
the processing includes
processing of, based on a case that a radio bearer identity included in the radio bearer configuration information element is not part of a configuration of the terminal apparatus and that the radio bearer configuration information element includes a Service Data Adaptation Protocol (SDAP) configuration information element and that a value of a Protocol Data Unit (PDU) session information element included in the SDAP configuration information element is not part of the configuration of the terminal apparatus, indicating to upper layers that a user-plane resource is configured for a PDU session corresponding to the value of the PDU session information element.
4. The base station apparatus according to claim 3 , wherein
the configuration of the user-plane resource includes a configuration related to a radio bearer.
5. A method for a terminal apparatus for communicating with a base station apparatus, the method comprising:
receiving, from the base station apparatus, a Radio Resource Control (RRC) reconfiguration message including a radio bearer configuration information element; and
based on a case that a radio bearer identity included in the radio bearer configuration information element is not part of a configuration of the terminal apparatus and that the radio bearer configuration information element includes a Service Data Adaptation Protocol (SDAP) configuration information element and that a value of a Protocol Data Unit (PDU) session information element included in the SDAP configuration information element is not part of the configuration of the terminal apparatus, indicating to upper layers that a user-plane resource is configured for a PDU session corresponding to the value of the PDU session information element.
6. A method for a base station apparatus for communicating with a terminal apparatus, the method comprising:
transmitting an RRC reconfiguration message to the terminal apparatus; and
including a radio bearer configuration information element in the RRC reconfiguration message to cause the terminal apparatus to perform processing, wherein
the processing includes
processing of, based on a case that a radio bearer identity included in the radio bearer configuration information element is not part of a configuration of the terminal apparatus and that the radio bearer configuration information element includes a Service Data Adaptation Protocol (SDAP) configuration information element and that a value of a Protocol Data Unit (PDU) session information element included in the SDAP configuration information element is not part of the configuration of the terminal apparatus, indicating to upper layers that a user-plane resource is configured for a PDU session corresponding to the value of the PDU session information element.
