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.
Claims19
A method of a user equipment (UE), comprising:
- detecting that an aggregate of calculated uplink transmit power of the UE exceeds a threshold;
- and
- in response to the detecting, adjusting a power of at least one uplink transmission of a plurality of frequency-division multiplexing (FDM)-based uplink transmissions of the UE over corresponding wireless connections with respective wireless access network nodes;
- wherein the adjusting:
- comprises reducing the power of the at least one uplink transmission or dropping the at least one uplink transmission,
- is according to at least one prioritization rule specifying that a first uplink transmission comprising a first uplink control channel transmission or traffic channel transmission containing acknowledgement information has a higher priority than a second uplink transmission comprising a second uplink control channel transmission or traffic channel transmission without acknowledgement information, wherein the first and second uplink transmissions are time misaligned;
- wherein:
- when the second uplink transmission is transmitted earlier than the first uplink transmission, the adjusting is performed over a part of a full transmission time period of the second uplink transmission, wherein the part is an overlapping time region between the first and second uplink transmissions, and
- when the first uplink transmission is transmitted earlier than the second uplink transmission and the first and second uplink transmissions are time misaligned and overlap in time, the adjusting is performed over the full transmission time period of the second uplink transmission.

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 the UE exceeds a threshold;
- and
- in response to the detecting, adjust a power of at least one uplink transmission of a plurality of frequency-division multiplexing (FDM)-based uplink transmissions of the UE over corresponding wireless connections with the wireless access network nodes;
- wherein the adjusting:
- comprises reducing the power of the at least one uplink transmission or dropping the at least one uplink transmission,
- is according to at least one prioritization rule specifying that a first uplink transmission comprising a first uplink control channel transmission or traffic channel transmission containing acknowledgement information has a higher priority than a second uplink transmission comprising a second uplink control channel transmission or traffic channel transmission without acknowledgement information, wherein the first and second uplink transmissions are time misaligned;
- wherein:
- when the second uplink transmission is transmitted earlier than the first uplink transmission, the adjusting is performed over a part of a full transmission time period of the second uplink transmission, wherein the part is an overlapping time region between the first and second uplink transmissions, and
- when the first uplink transmission is transmitted earlier than the second uplink transmission and the first and second uplink transmissions are time misaligned and overlap in time, the adjusting is performed over the full transmission time period of the second uplink transmission.

A non-transitory machine-readable storage medium comprising instructions that upon execution cause a user equipment (UE) to:
- detect that an aggregate of calculated uplink transmit power of the UE exceeds a threshold;
- and
- in response to the detecting, adjust a power of at least one uplink transmission of a plurality of frequency-division multiplexing (FDM)-based uplink transmissions of the UE over corresponding wireless connections with respective wireless access network nodes;
- wherein the adjusting:
- comprises reducing the power of the at least one uplink transmission or dropping the at least one uplink transmission,
- is according to at least one prioritization rule specifying that a first uplink transmission comprising a first uplink control channel transmission or traffic channel transmission containing acknowledgement information has a higher priority than a second uplink transmission comprising a second uplink control channel transmission or traffic channel transmission without acknowledgement information, wherein the first and second uplink transmissions are time misaligned;
- wherein:
- when the second uplink transmission is transmitted earlier than the first uplink transmission, the adjusting is performed over a part of a full transmission time period of the second uplink transmission, wherein the part is an overlapping time region between the first and second uplink transmissions, and
- when the first uplink transmission is transmitted earlier than the second uplink transmission and the first and second uplink transmissions are time misaligned and overlap in time, the adjusting is performed over the full transmission time period of the second uplink transmission.
