20100260340 | COMMUNICATION SYSTEM, RESPONSE NOTIFYING METHOD AND APPARATUS - To solve a problem that unless all of a plurality of AICH signature states are correctly decoded, the contents of reception results cannot be recognized and the error rate of signature decoding will be high. In this embodiment, a base station uses, out of a signature combination, the signature of at least one predetermined position to indicate information containing a preamble reception result and uses the signature of a position other than the predetermined position to indicate a transmission profile information number of an uplink channel for notification to a user equipment. Thus, the error rate related to reception results can be reduced as compared with the case where a single signature combination is used to notify all pieces of information. | 10-14-2010 |

20110014876 | RADIO COMMUNICATION METHOD AND SYSTEM - The first communication apparatus transmits existence confirmation request notices to the second communication apparatus, using the first frequency band and the second frequency band that is a frequency band different from the first frequency band.

The first communication apparatus, after having received one or more of the existence confirmation response notices transmitted from the second communication apparatus, exchanges data with the second communication apparatus, using the frequency band that corresponds to the existence confirmation response notice transmitted through the higher frequency band among the first and second frequency bands. | 01-20-2011 |
