US 11,310,748 B2 · Dynamic power reduction requests for wireless communications

Abstract

Methods and systems for controlling uplink (UL) transmission power of a user equipment (UE) electronic device includes determining, using the UE electronic device, that a maximum power availability for a transmission between the UE and a wireless network node is not appropriate to current conditions. Based on the determination that maximum power availability is not appropriate the UE electronic device sends a request to the wireless network node to reduce power for communication with the wireless network node. Based on the request, the UE electronic device communicates at a reduced power level for communications with the wireless network node.

Claims20

Dependent claims

An electronic device, comprising:

one or more antennas configured to communicate with one or more wireless network nodes;
and
memory storing instructions that, when executed by one or more processors, are configured to cause the one or more processors to:
encode maximum allowed transmit power (PCMAX) values to incorporate power reductions for a plurality of cells through which the electronic device connects to one or more wireless networks;
cause the one or more antennas to transmit the PCMAX values from the electronic device to respective cells of the plurality of cells using power headroom reports;
and
cause the one or more antennas to communicate with a cell of the plurality of cells using a permissible power usage level corresponding to a respective power headroom report of the power headroom reports.
