METHODS AND APPARATUS FOR REDUCING MODEM POWER BASED ON A PRESENT STATE OF CHARGE OF BATTERY

摘要

Methods, systems, and devices are described for managing power of a user equipment (UE). A UE modem may determine the state of charge of the battery to determine that the battery is in one of two or more charge state levels, and may invoke one or more modem power saving modes based on the charge state level. Power saving modes may include, for example, reducing a number of available receive chains in a UE, initiating a time delay between one or more frequency scan requests performed by the UE, reducing a rate of neighbor search requests performed by the UE, providing a buffer status report (BSR) parameter that indicates a reduced amount of buffer data relative to an actual amount of buffer data for the UE, and/or adjusting a maximum transmit power level for an uplink channel.

主权项

1. A method for managing power of a user equipment (UE) in a wireless communications network, comprising:
determining a present state of charge of an internal power source of the UE; and adjusting, responsive to the determining, one or more modem control parameters of a modem of the UE, the adjusting including a reduction in a number of receive chains of the UE available for use by the modem.
