Claim of US Patent No. 10,602,539

1. A wireless terminal apparatus for communicating with a base station apparatus with radio communication, the wireless terminal apparatus comprising:a receiving section for receiving a data packet including control information and communication data; and
a control section for controlling wireless communication to the base station apparatus using a plurality of terminal identifiers that includes a first terminal identifier and a second terminal identifier, the plurality of terminal identifiers assigned to the wireless terminal apparatus,
wherein:
the control information included in the data packet includes a first region to identify a terminal apparatus and a second region to control the wireless communication,
a sum of an amount of information bits of the first region and an amount of information bits of the second region is constant,
the amount of information bits of the first region is a first information amount or a second information amount,
the first region is used for identifying each of the plurality of the terminal identifiers,
all information bits in the first region from the received data packet are used to identify the terminal apparatus;
a first communication method uses the first terminal identifier that is included in the first region and that has the first information amount,
a second communication method uses the second terminal identifier that is included in the first region and that has the second information amount,
the first information amount is greater than the second information amount,
the control section is further configured to use, based on (i) the first region including the second terminal identifier and (ii) the second terminal identifier having the second information amount, a part of the second region that corresponds to a difference between the first information amount and the second information amount.
