1. A method of performing reverse link power control in a mobile network by a first device that is configured to receive and to transmit signals to a wireless access terminal, the method comprising:
- generating, using data from a first outer power control loop and data from a second outer power control loop, a power control command for a reverse link channel by performing functions comprising;
deriving, in the first outer power control loop executing on the first device, a first power control threshold value for reverse link power of the reverse link channel;
receiving, from a second device operating the second outer power control loop substantially simultaneously with the first outer power control loop, a second power control threshold value for reverse link power of the reverse link channel;
selecting the first power control threshold value, derived in the first outer power control loop executing on the first device, or the second power control threshold value, received from the second device operating the second outer power control loop, as a selected power control threshold value for the reverse link channel;
deriving, in an inner power control loop executing on the first device, the power control command for the reverse link channel from the selected power control threshold value; and
transmitting, to the wireless access terminal, the power control command for the reverse link channel,wherein the first power control threshold value for the reverse link channel is derived independently of the second outer power control loop for the reverse link channel.

Abstract
This description describes examples of performing reverse link power control in a mobile network having a plurality of first modem devices that receive and transmit signals to wireless access terminals (ATs) and a second device in communication with the plurality of first devices. One of the first devices derives a first power control threshold (PCT) value for reverse link power of one of the access terminals (ATs) and the second device derives a second power control threshold (PCT) value for reverse link power of the one of the ATs. The second power control threshold (PCT) value is transmitted using a data traffic path and either the first PCT value or the second PCT value is selected.

14. A system for performing reverse link power control of a reverse link channel, the system comprising:
-
a first device configured to use data from a first outer power control loop and data from a second outer power control loop to generate a power control command for the reverse link channel, the first device further configured to receive and to transmit signals to a wireless access terminal, to execute the first outer power control loop to derive a first power control threshold value for reverse link power of the reverse link channel, and to execute an inner power control loop to derive the power control command from a selected power control threshold value; and a second device configured to execute the second outer power control loop substantially simultaneously with the first power control loop to derive a second power control threshold value for reverse link power of the reverse link channel, wherein the first device is configured to select the first power control threshold value, derived in the first outer power control loop executing on the first device, or the second power control threshold value, derived in the second outer power control loop executing on the second device, as the selected power control threshold value, wherein the first device is configured to transmit the power control command for the reverse link channel to the wireless access terminal, and wherein the first power control threshold value for the reverse link channel is derived independently of the second outer power control loop for the reverse link channel. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. One or more non-transitory computer-readable storage media having instructions stored thereon that, when executed by one or more processing devices that are configured to receive and to transmit signals to a wireless access terminal in a mobile network, cause the one or more processing devices to:
-
generate, using data from a first outer power control loop and data from a second outer power control loop, a power control command for a reverse link channel by performing functions comprising; deriving, in the first outer power control loop executing on said a first device, a first power control threshold value for reverse link power of the reverse link channel; receiving, from a second device operating the second outer power control loop substantially simultaneously with the first outer power control loop, a second power control threshold value for reverse link power of the reverse link channel; selecting the first power control threshold value, derived in the first outer power control loop executing on the first device, or the second power control threshold value, received from the second device operating the second outer power control loop, as a selected power control threshold value; deriving, in an inner power control loop executing on the first device, the power control command for the reverse link channel from the selected power control threshold value; and transmitting to the wireless access terminal the power control command for the reverse link channel, wherein the first power control threshold value for the reverse link channel is derived independently of the second outer power control loop for the reverse link channel. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
