Abstract

Control circuitry in a terminal apparatus generates one or more groups, each group including a selected plurality of communication methods whose total value of specific absorption rates (SARs) is equal to or less than a threshold value, and generates group information indicating the one or more groups. N transmitters transmit transmission data to a plurality of communication stations that respectively support the plurality of communication methods included in one group that is indicated by the group information, by using corresponding communication methods.

First claim

What is claimed is:

1. A terminal apparatus comprising:
a display which, in operation, displays a plurality of communication methods and first group information indicating a combination of two or more simultaneously operable communication methods whose total value of specific absorption rates (SARs) is equal to or less than a threshold value;
control circuitry which, in operation,
prompts a user of the terminal apparatus to select one communication method from the displayed plurality of communication methods, which is to be added to the first group information, and
updates the first group information by adding the selected one communication method to the combination of two or more simultaneously operable communication methods if a total value of a first SAR value of the two or more simultaneously operable communication methods and the first SAR value of the selected one communication method is equal to or less than a first threshold value; and

a transmitter which, in operation, transmits transmission data to a plurality of communication stations that respectively support the two or more simultaneously operable communication methods and the added one communication method, which are indicated by the updated first group information, by using corresponding communication methods.

2. The terminal apparatus according to claim 1 , further comprising:
a receiver which, in operation, receives reception data, wherein
the transmitter transmits the first group information through at least one communication station,
the receiver receives the reception data through the plurality of communication stations that respectively support the two or more simultaneously operable communication methods.

3. The terminal apparatus according to claim 2 , wherein
the display, in operation, displays a plurality of group information that include the first group information, and
each of the plurality of group information indicates a combination of two or more simultaneously operable communication methods whose total value of SARs is equal to or less than the threshold value.

4. The terminal apparatus according to claim 3 , wherein
when the user selects one of the plurality of group information, the transmitter transmits the selected one of the plurality of group information.

5. The terminal apparatus according to claim 4 , wherein
the selected one of the plurality of group information is switched to another one of the plurality of group information in a time axis direction.

6. The terminal apparatus according to claim 4 , wherein
the selected one of the plurality of group information is switched to another one of the plurality of group information during a transition period between a transmission timing and a reception timing for the terminal apparatus.

7. The terminal apparatus according to claim 4 , wherein the display, in operation, receives input from the user, and
the control circuitry selects the one of the plurality of group information based on the input to the display from the user.

8. The terminal apparatus according to claim 7 , wherein
the display, in operation, displays a transmission rate for each of the two or more simultaneously operable communication methods supported by the terminal apparatus and an overall transmission rate corresponding to each of the plurality of group information.

9. The terminal apparatus according to claim 3 , wherein
the transmitter transmits the plurality of group information,
one of the plurality of group information is selected by a device other than the terminal apparatus, and
the reception data is allocated to the plurality of communication stations that respectively support the two or more simultaneously operable communication methods indicated by the selected one of the generated plurality of group information.

10. The terminal apparatus according to claim 1 , wherein
the control circuitry, in operation, updates the first group information, by adding the selected one communication method to the combination of two or more simultaneously operable communication methods if the total value of the first SAR value of the two or more simultaneously operable communication and the first SAR value of the selected one communication method is equal to or less than the first threshold value and if a total value of a second SAR value of the two or more simultaneously operable communication methods indicated and the second SAR value of the selected one communication method is equal to or less than a second threshold value.

11. The terminal apparatus according to claim 10 , wherein
the control circuitry, in operation, holds the first SAR value and the second SAR value for each of the two or more communication methods supported by the terminal apparatus, and holds the first threshold value for the first SAR value and the second threshold value for the second SAR value.

12. A communication method comprising:
displaying, on a display, a plurality of communication methods and displaying first group information indicating a combination of two or more simultaneously operable communication methods whose total value of specific absorption rates (SARs) is equal to or less than a threshold value;
prompting a user to select one communication method from the displayed plurality of communication methods, which is to be added to the first group information, and
updating the first group information by adding the selected one communication method to the combination of two or more simultaneously operable communication methods if a total value of a first SAR value of the two or more simultaneously operable communication methods and the first SAR value of the selected one communication method is equal to or less than a first threshold value; and
transmitting transmission data to a plurality of communication stations that respectively support the two or more simultaneously operable communication methods and the added one communication method, which are indicated by the updated first group information, by using corresponding communication methods.
