In a communication system 100, failures can be determined without field testing in the following manner. For each transmission, a communication unit 104 determines the signal quality of the transmission. When the signal quality of the transmission is unfavorable, the communication unit 104 determines its location within the communication system 100 and the time the transmission was transmitted. Having stored this information, the communication unit 104 transmits it to a communication resource allocator 101. Upon receiving this information, the communication resource allocator 101 determines a cause for the unfavorable signal quality.
