WIRELESS COMMUNICATION DEVICE, AND WIRELESS COMMUNICATION SYSTEM

1 . A wireless communication device comprising:

a controller configured to:

configure a plurality of entities for requirements of data to be transmitted by a radio bearer;

configure communication channels with different communication configurations for the respective entities;

select one entity and one communication channel in accordance with a state of the data; and

control data communication with a counterpart wireless communication device.

2 . The wireless communication device according to claim 1 , wherein the controller is further configured to:

configure a first entity performing a process of a first protocol for the data to be transmitted by the radio bearer;

configure a second entity performing a process of a second protocol for the data; and

configure a plurality of third entities performing a process of a third protocol for the data and associated with the communication channels with different communication configurations, wherein

the second entity selects the communication channel with the communication configuration relevant to the state of the data and sends the data to the third entity associated with the selected communication channel.

3 . The wireless communication device according to claim 2 , wherein the second entity selects the communication channel in accordance with a time at which the data arrives at the second entity and a delay time allowed for the data.
