Initial access setting information generating apparatus, method, and program, and base station apparatus

摘要

An initial access setting information generating apparatus includes a preamble information transmission number obtaining unit that receives and obtains the number of transmissions for preamble information in a non-contention type initial access procedure performed between a base station and a communication terminal, where the preamble information transmission number obtaining unit receives and obtains the number of transmissions after the initial access procedure is completed; an expected reception power determination unit that determines an expected reception power at the base station, based on the number of transmissions for the preamble information, which is obtained by the preamble information transmission number obtaining unit; and a set value communication unit that generates and outputs initial access setting information about the initial access procedure for the communication terminal, based on the expected reception power determined by the expected reception power determination unit.

1. An initial access setting information generating apparatus comprising:
a reception information selecting unit wherein when an initial access procedure performed between a base station and a communication terminal has been completed, the reception information selecting unit determines whether the initial access procedure is of a non-contention type or a contention type, and: if determining that the initial access procedure is of the non-contention type, the reception information selecting unit outputs number of transmissions for preamble information in the initial access procedure, the number being supplied from the communication terminal, as non-contention type preamble transmission number, and if determining that the initial access procedure is of the contention type, the reception information selecting unit outputs number of transmissions for preamble information as contention type preamble transmission number; an expected reception power determination unit that determines an expected reception power at the base station, based on the non-contention type preamble transmission number output from the reception information selecting unit and a determined success rate; and a set value communication unit that generates and outputs initial access setting information about the initial access procedure for the communication terminal, based on the expected reception power determined by the expected reception power determination unit.
