Wireless communication system, wireless terminal, and wireless communication method

A wireless terminal comprising:

• an antenna configured to communicate with at least one base station forming a plurality of cells including at least one first cell and at least one second cell, each of the at least one first cell being a cell to which a wireless terminal is able to couple without coupling to another cell, each of the at least one second cell being a cell to which a wireless terminal is unable to couple without coupling to another cell, each of the at least one first cell being a cell in which each of at least one first known signal is transmitted in accordance with a first rule, each of the at least one second cell being a cell in which each of at least one second known signal is transmitted in accordance with a second rule;
• and
• a processor configured to:
• identify, when coupling to no cell, at least one known signal being at least a part of the at least one first known signal based on the first rule, the at least one known signal being received from the at least one first cell,
• select a cell being one of the at least one first cell based on the identified at least one known signal, and
• couple to the selected cell being one of the at least one first cell.

A wireless communication method comprising:

• forming a plurality of cells including at least one first cell and at least one second cell by at least one base station, each of the at least one first cell being a cell to which a wireless terminal is able to couple without coupling to another cell, each of the at least one second cell being a cell to which a wireless terminal is unable to couple without coupling to another cell, each of the at least one first cell being a cell in which each of at least one first known signal is transmitted in accordance with a first rule, each of the at least one second cell being a cell in which each of at least one second known signal is transmitted in accordance with a second rule;
• identifying by a specific wireless terminal, when the specific wireless terminal couples to no cell, at least one known signal being at least a part of the at least one first known signal based on the first rule, the at least one known signal being received from the at least one first cell;
• selecting by the wireless specific terminal, a cell being one of the at least one first cell based on the identified at least one known signal;
• and
• coupling by the specific wireless terminal, to the selected cell being one of the at least one first cell.
