When I read papers, outage in relayed network is defined in two ways,

(a) some papers say outage probability as the probability that SNR is below a threshold level,

(b) other papers say probability that transmission rate is greater than end-to-end support rate.

Does the definition of outage probability in (a) is same as the (b) with relationship [2][/NR]-1 as the SNR threshold, or if outage probability definition of (a) has its own significance. Lets say if I am not interested in end-to-end data rate, and consider SNR at the destination to be higher than a threshold value for successful reception of the signal, the outage probability definition according to (a) can be used. Please let me know if I am right or not.

Thanks.
