Managing power consumption of transmission circuitry in a wireless communication device

摘要

Methods, apparatuses and computer readable media are described that manage transmit power levels for a wireless device connected to a network access system of a wireless network. Processing circuitry in the wireless device obtains a target average transmit power level. Based on estimates of an actual average transmit power level for a sliding window of a past time period and the target average transmit power level, the processing circuitry determines a target transmit power level, a duty cycle percentage, and a transmit pattern of transmit on frames and transmit off frames for a future time period. The processing circuitry sends to the access network system signaling messages indicating non-zero valued buffer status reports for the transmit on frames and zero valued buffer status reports for the transmit off frames. Non-zero values correspond to actual amounts of pending uplink data, while zero values are sent irrespective of actual uplink buffer status.

1. A method to adapt transmission circuitry to realize a target average transmit power level in a wireless communication device connected to a wireless network, the method comprising:
by the wireless communication device:
obtain a target average transmit power level;estimate an actual average transmit power level for a recent past time period by at least calculating an average transmit power level over a sliding window that includes the recent past time period;determine a target transmit power level for a future time period;determine a duty cycle percentage for the future time period;determine a transmit pattern of transmit on frames and transmit off frames for the future time period; andsend to an access network system of the wireless network a first set of one or more signaling messages indicating a non-zero amount of data associated with the transmit on frames and a second set of one or more signaling messages indicating a zero amount of data associated with the transmit off frames.
