Abstract
A user equipment detects that an aggregate of calculated uplink transmit power of the UE exceeds a threshold. In response to the detecting, a power of at least one of a plurality of frequency-division multiplexing (FDM)-based uplink transmissions of the UE over corresponding wireless connections with respective wireless access network nodes is adjusted.
Claims20
A method of a user equipment (UE), comprising:
- detecting that an aggregate of calculated uplink transmit power of a plurality of frequency-division multiplexing (FDM)-based uplink transmissions of the UE over corresponding wireless connections with respective wireless access network nodes exceeds a threshold;
- and
- in response to the detecting, adjusting a power of the plurality of FDM-based uplink transmissions of the UE over the corresponding wireless connections with the respective wireless access network nodes,
- wherein the FDM-based uplink transmissions are concurrent uplink transmissions, and wherein a first wireless access network node of the wireless access network nodes provides carrier aggregation having component carriers, and a subset of the concurrent uplink transmissions includes plural uplink transmissions over wireless connections on the component carriers of the first wireless access network node, and a remainder of the concurrent uplink transmissions include one or more uplink transmissions over one or more wireless connections with a second wireless access network node of the wireless access network nodes.

A user equipment (UE) comprising:
- a communication component to communicate wirelessly with wireless access network nodes;
- and
- at least one processor configured to:
- detect that an aggregate of calculated uplink transmit power of a plurality of frequency-division multiplexing (FDM)-based uplink transmissions of the UE over corresponding wireless connections with respective wireless access network nodes exceeds a threshold;
- and
- in response to the detecting, adjust a power of the plurality of FDM-based uplink transmissions of the UE over the corresponding wireless connections with the respective wireless access network nodes,
- wherein the FDM-based uplink transmissions are concurrent uplink transmissions, and wherein a first wireless access network node of the wireless access network nodes provides carrier aggregation having component carriers, and a subset of the concurrent uplink transmissions includes plural uplink transmissions over wireless connections on the component carriers of the first wireless access network node, and a remainder of the concurrent uplink transmissions include one or more uplink transmissions over one or more wireless connections with a second wireless access network node of the wireless access network nodes.
