Abstract
[Object] To provide a base station device, a terminal device, a communication system, a communication method, and an integrated circuit which are capable of significantly improving the transmission efficiency of the entire system in a communication system in which a base station device and a terminal device communicate with each other. [Solution] A base station device, including: a control unit configured to variably set a sub carrier interval and a symbol length used for communication and notify of information for switching a parameter set indicating the sub carrier interval and the symbol length in accordance with setting content.
Claims18
A base station device, comprising:
- circuitry configured to
- determine that a sub carrier interval and a symbol length used for communication with a terminal device are insufficient, and
- in response to a determination that the sub carrier interval and the symbol length used for the communication with the terminal device are insufficient,
- variably set the sub carrier interval and the symbol length used for the communication with the terminal device and notify the terminal device of information for switching a parameter set indicating the sub carrier interval and the symbol length, the symbol length being variably set by selecting the parameter set from a plurality of parameter sets indicating different numbers of symbols, and
- determine a time at which the switching will take place, wherein the information for switching includes an indication of a time period from notification of the information for switching to the time at which the switching will take place,
- wherein the information for switching is included in radio resource control (RRC) signaling and transmitted.
A terminal device, comprising:
- circuitry configured to
- in a case in which a sub carrier interval and a symbol length used for communication with a base station are insufficient, receive, from the base station, a resource in which the sub carrier interval and the symbol length are variably set on a basis of information notified of to switch a parameter set indicating the sub carrier interval and the symbol length, the symbol length being variably set by selecting the parameter set from a plurality of parameter sets indicating different numbers of symbols,
- wherein the resource includes an indication of a time period from notification of the resource to a time at which switching of the parameter set will take place, and
- wherein the information for switching is included in radio resource control (RRC) signaling and transmitted.
A method, comprising:
- determining, by a processor, that a sub carrier interval and a symbol length used for communication with a terminal device are insufficient, and
- in response to a determination that the sub carrier interval and the symbol length used for the communication with the terminal device are insufficient,
- variably setting, by the processor, the sub carrier interval and the symbol length used for the communication with the terminal device and notifying the terminal device of information for switching a parameter set indicating the sub carrier interval and the symbol length, the symbol length being variably set by selecting the parameter set from a plurality of parameter sets indicating different numbers of symbols, and
- determining a time at which the switching will take place, wherein the information for switching includes an indication of a time period from notification of the information for switching to the time at which the switching will take place,
- wherein the information for switching is included in radio resource control (RRC) signaling and transmitted.
A method, comprising:
- in a case in which a sub carrier interval and a symbol length used for communication with a base station are insufficient, receiving from the base station, by a processor, a resource in which the sub carrier interval and the symbol length are variably set on a basis of information notified of to switch a parameter set indicating the sub carrier interval and the symbol length, the symbol length being variably set by selecting the parameter set from a plurality of parameter sets indicating different numbers of symbols,
- wherein the resource includes an indication of a time period from notification of the resource to a time at which switching of the parameter set will take place, and
- wherein the information for switching is included in radio resource control (RRC) signaling and transmitted.
A non-transitory, computer-readable storage medium having a program stored therein, the program causing a computer to determine that a sub carrier interval and a symbol length used for communication with a terminal device are insufficient, and
- in response to a determination that the sub carrier interval and the symbol length used for the communication with the terminal device are insufficient,
- variably set the sub carrier interval and the symbol length used for the communication with the terminal device and notify the terminal device of information for switching a parameter set indicating the sub carrier interval and the symbol length, the symbol length being variably set by selecting the parameter set from a plurality of parameter sets indicating different numbers of symbols, and
- determine a time at which the switching will take place, wherein the information for switching includes an indication of a time period from notification of the information for switching to the time at which the switching will take place,
- wherein the information for switching is included in radio resource control (RRC) signaling and transmitted.
A non-transitory, computer-readable storage medium having a program stored therein, the program causing a computer to in a case in which a sub carrier interval and a symbol length used for communication with a base station are insufficient, receive from the base station, a resource in which the sub carrier interval and the symbol length are variably set on a basis of information notified of to switch a parameter set indicating the sub carrier interval and the symbol length, the symbol length being variably set by selecting the parameter set from a plurality of parameter sets indicating different numbers of symbols,
- wherein the resource includes an indication of a time period from notification of the resource to a time at which switching of the parameter set will take place, and
- wherein the information for switching is included in radio resource control (RRC) signaling and transmitted.
