Apparatus, systems and methods for power management in mobile devices
First Claim
1. A method, comprising:
- at a user equipment (UE) that communicates with a wireless network via a base station;
determining whether a battery alarm of the UE is asserted;
reducing a transmission duty cycle of the UE to zero for a first predetermined time period when the battery alarm is asserted;
determining whether the battery alarm has been de-asserted after the first predetermined time period; and
when the battery alarm has not been de-asserted, increasing the transmission duty cycle to a first threshold level for a second predetermined time period, wherein the first threshold level is less than a full transmission duty cycle of the UE.

Abstract
An apparatus, system and method for determining whether a battery alarm of a UE is asserted, reducing a transmission duty cycle of the UE to zero for a first predetermined time period when the battery alarm is asserted, determining whether the battery alarm has been de-asserted after the first predetermined time period and when the battery alarm has not been de-asserted, increasing the transmission duty cycle to a first threshold level for a second predetermined time period, wherein the first threshold level is less than a full transmission duty cycle of the UE. When the battery alarm has been de-asserted, increasing the transmission duty cycle to a second threshold level for a third predetermined time period, wherein the second threshold level is less than the full transmission duty cycle of the UE, and wherein the second threshold level is greater than the first threshold level.

13. A user equipment (“
- UE”
), comprising;a battery; a power management component that monitors the battery and asserts a battery alarm; and a baseband processor that controls a transmission duty cycle of the UE, wherein the baseband processor reduces the transmission duty cycle of the UE to zero for a first predetermined time period when the battery alarm is asserted and wherein, after the first predetermined time period, the baseband processor further increases the transmission duty cycle to a first threshold level for a second predetermined time period when the battery alarm continues to be asserted and increases the transmission duty cycle to a second threshold level for a third predetermined time period when the battery alarm has been de-asserted. - View Dependent Claims (14, 15, 16, 17, 18)

19. A baseband processor of a user equipment (“
- UE”
), comprising;a general purpose input receiving an indication that a battery alarm has been asserted for the UE; and circuitry configured to control a transmission duty cycle of the UE, wherein the circuitry reduces the transmission duty cycle of the UE to zero for a first predetermined time period when the battery alarm is asserted and wherein, after the first predetermined time period, the circuitry further increases the transmission duty cycle to a first threshold level for a second predetermined time period when the battery alarm continues to be asserted and increases the transmission duty cycle to a second threshold level for a third predetermined time period when the battery alarm has been de-asserted. - View Dependent Claims (20)
