Abstract
Abstract A method of calculating a power threshold for a secondary communication channel capable of operating in DTX mode in forward or reverse links so that the communication channel is prevented from entering a deadlock state. Power threshold information for an associated primary channel and the secondary channel are used to update the established power threshold for the communication channel. The updated power threshold for the communication is thus calculated by combining previously established thresholds for the communication channel and associated primary channel with a current established threshold for the associated primary channel.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
72 words
A method of performing power control for a communication channel with DTX mode capability, the method comprising the steps of: establishing power thresholds for the communication channel and its associated primary channel; and calculating an updated power threshold for the communication channel when the communication channel is in DTX mode where the updated power threshold is based on received power threshold information for the communication channel and its associated primary communication channel.
Claim 2
Independent Claim
72 words
A method of performing power control for a communication channel with DTX mode capability, the method comprising the steps of: establishing power thresholds for the communication channel and its associated primary channel; and calculating an updated power threshold for the communication channel when the communication channel is in DTX mode where the updated power threshold is based on received power threshold information for the communication channel and its associated primary communication channel.
Claim 3
Dependent Claim
18 words
The method of claim 1 where the steps are performed at an MSC of a wireless communication system.
Claim 4
Dependent Claim
19 words
The method of claim 1 where the steps are performed at a base station of a wireless communication system.
Claim 5
Dependent Claim
18 words
The method of claim 1 where the steps are performed by user equipment of a wireless communication system.
Claim 6
Dependent Claim
20 words
The method of claim 1 where the communication channel and associated communication channels are secondary channels with DTX mode capability.
Claim 7
Dependent Claim
49 words
The method of claim 1 where the step of establishing power threshold information comprises: receiving power level measurement information for the communication channel and its associated primary channel; and selecting a threshold that is based on the power level measurement information and which is associated with an acceptable FER.
Claim 8
Dependent Claim
46 words
The method of claim 1 where the step of calculating an updated power threshold comprises combining previously established thresholds for the communication channel and its associated primary communication channel with a current established threshold for the primary communication channel based on the received power threshold information.
Claim 9
Dependent Claim
91 words
The method of claim 7 where the established power threshold for the communication channel based on information received at time instant k is P(k) and the established power threshold for the associated primary channel based on information received at time instant k is S(k) and the established power threshold for the primary channel based on information received at time instant (k+1) is P(k+1) and where the calculated power threshold for the communication channel at time instant (k+1) is S(k+1) where S(k+1)=P(k+1)+S(k)−P(k) and k is an integer equal to 1 or greater.
