Abstract:
1. A communication apparatus comprising: a threshold value controller for determining a threshold value based on a radio line quality between a transmission destination of said transmission signal and the communication apparatus; and a transmission controller for deferring or ceasing transmission of transmission signal when a received power of a received signal exceeds said threshold value, where when receiving a signal said threshold value controller records in a threshold value table transmission source information on received signals and threshold values corresponding to received powers of said received signals in one-to-one correspondence, and extracts a threshold value corresponding to said transmission destination from said threshold value table to decide whether or not transmission of said transmission signal is deferred or ceased, wherein, when both transmission source information on a received signal and a second threshold value corresponding to the received power of the received signal are recorded on said threshold value table, if said transmission source information already exists in said threshold value table, said threshold value controller rewrites a first threshold value already recorded on said threshold value table and corresponding to said transmission source information into a value obtained by weight adding said first value and said second value.
