Method and system for selective power control of wireless coverage areas
First Claim
1. A method for controlling transmission power between a wireless communication device (WCD) and a radio access network (RAN), wherein the WCD is served by a plurality of wireless coverage areas defined by the RAN, the method comprising:
- receiving into the RAN from the WCD a plurality of power adjustment commands;
for each received power adjustment command, responsively identifying one or more wireless coverage areas in which to adjust transmission power, and adjusting the transmission power in each of the identified one or more wireless coverage areas, wherein identifying the one or more wireless coverage areas comprises;
(a) making a determination of whether the RAN has received a threshold extent of power adjustment commands from the WCD;
(b) if the determination is that the RAN has not received the threshold extent of power adjustment commands from the WCD, identifying as the one or more wireless coverage areas a first subset of the plurality of wireless coverage areas; and
(c) if the determination is that the RAN has received the threshold extent of power adjustment commands from the WCD, identifying as the one or more wireless coverage areas a second subset of the plurality of wireless coverage areas, wherein the second subset is different than the first subset.

Abstract
In methods and systems for adjusting forward link transmit power of wireless coverage areas, forward link signal strength is observed to obtain a signal-to-noise ratio (SNR) and/or an observed frame error rate (FER) for the received signal. A determination is made whether to request a forward link power adjustment. If the determination is that a forward link power adjustment is required, a request may be made into a radio access network (RAN) to adjust power. The RAN may select a subset of wireless coverage areas in which to adjust power. If further power adjustment is required, a further request may be made into the RAN, and the RAN may select a different subset of wireless coverage areas in which to adjust power.

11. A method for controlling transmission power between a wireless communication device (WCD) and a radio access network (RAN), wherein the WCD is served by a plurality of wireless coverage areas defined by the RAN, the method comprising:
-
receiving into the RAN from the WCD a plurality of power increase commands, including at least a first set of power increase commands and a second set of power increase commands; responsive to each power increase command of the first set, increasing transmission power in a first subset of the plurality of wireless coverage areas; and responsive to each power increase command in the second set, increasing transmission power in a second subset of the plurality of wireless coverage areas, wherein the second subset is larger than the first subset and includes the first subset. - View Dependent Claims (12, 13, 14)

15. A system for controlling power transmission between a wireless communication device (WCD) and a radio access network (RAN), wherein the WCD is served by a plurality of wireless coverage areas defined by the RAN, the RAN comprising:
-
one or more base transceiver stations (BTS'"'"'s); one or more base station controllers (BSC'"'"'s); wherein the one or more BSC'"'"'s control the one or more BTS'"'"'s; wherein the one or more BTS'"'"'s radiate to define the plurality of wireless coverage areas; wherein the RAN receives a plurality of power increase commands, including at least a first set of power increase commands and a second set of power increase commands; wherein in response to each power increase command of the first set, the RAN increases power in a first subset of the plurality of wireless coverage areas; and wherein in response to each power increase command of the second set, the RAN increases power in a second subset of the plurality of wireless coverage areas, wherein the second subset is larger than the first subset and includes the first subset. - View Dependent Claims (16, 17, 18, 19, 20)
