Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for deciding transmission power in order to transmit at least one of secret data and non-secret data, the method comprising: determining whether data to be transmitted by a transmitting device is sensitive to a delay; determining whether both the secret data and the non-secret data are required to be simultaneously transmitted when the data to be transmitted is sensitive to the delay; acquiring a total channel capacity by applying different weights to the secret data and the non-secret data when the data to be transmitted is sensitive to the delay and it is determined that both the secret data and the non-secret data are required to be transmitted; and deciding transmission power to maximize the acquired total channel capacity.
2. The method of claim 1 , further comprising: determining whether both the secret data and the non-secret data are required to be simultaneously transmitted when it is determined that the data to be transmitted is not sensitive to the delay; deciding optimal transmission power by minimizing an outage probability when target secret transmission rate Rs is given in the case where it is determined that only the secret data is required to be transmitted; and deciding the target secret transmission rate Rs in order to maximize a system throughput.
3. The method of claim 2 , further comprising: calculating the outage probability by considering both the non-secret data and the secret data when it is determined that the data to be transmitted is not sensitive to the delay and it is determined that both the secret data and the non-secret data are required to be transmitted; and deciding transmission power to minimize the outage probability.
4. The method of claim 2 , further comprising: calculating the outage probability for each of the non-secret data and the secret data when it is determined that the data to be transmitted is not sensitive to the delay and it is determined that both the secret data and the non-secret data are required to be transmitted; and deciding transmission power to minimize the outage probability for the secret data while assuring a maximum value of the outage probability for the non-secret data.
5. The method of claim 2 , further comprising: calculating the outage probability for each of the non-secret data and the secret data when it is determined that the data to be transmitted is not sensitive to the delay and it is determined that both the secret data and the non-secret data are required to be transmitted; and deciding transmission power to minimize the outage probability for the non-secret data while assuring a maximum value of the outage probability for the secret data.
6. The method of claim 1 , further comprising: determining whether both the secret data and the non-secret data are required to be transmitted when it is determined that only some of the data to be transmitted is sensitive to the delay; and deciding transmission power to maximize an ergodic channel capacity of the secret data while meeting a minimum outage probability of the secret data when it is determined that only some of the data to be transmitted is sensitive to the delay and it is determined that only the secret data is required to be transmitted.
7. The method of claim 6 , further comprising: applying different weights to the non-secret data and the secret data in order to maximize a total channel capacity for the secret data and the non-secret data when it is determined that only some of the data to be transmitted is sensitive to the delay, but both the secret data and the non-secret data are required to be transmitted; and deciding the transmission power by considering both the outage probability for the non-secret data and the outage probability of the secret data.
8. The method of claim 6 , further comprising: applying different weights to the non-secret data and the secret data in order to maximize the total channel capacity for the secret data and the non-secret data when it is determined that only some of the data to be transmitted is sensitive to the delay, but both the secret data and the non-secret data are required to be transmitted; and deciding the transmission power by considering both the outage probability for the non-secret data and the outage probability of the secret data.
9. The method of claim 6 , further comprising: deciding transmission power to maximize a channel capacity for the secret data, but constraint the maximum value of the outage probability for the non-secret data in order to maximize the channel capacity for the secret data when it is determined that only some of the data to be transmitted is sensitive to the delay, but both the secret data and the non-secret data are required to be transmitted.
10. The method of claim 6 , further comprising: deciding transmission power to maximize a channel capacity for the non-secret data, but constraint the maximum value of the outage probability for the secret data in order to maximize the channel capacity for the non-secret data when it is determined that only some of the data to be transmitted is sensitive to the delay, but both the secret data and the non-secret data are required to be transmitted.
