Signal Power Management in a Multicarrier Wireless Device

摘要

A first signal is transmitted starting in a first subframe of a cell of a first cell group. A second signal is configured for transmission in a second subframe of a second cell group. Transmission of the second signal is dropped if a power value is more than an allowable transmission power. A calculation of the power value considers transmission power of the first signal and the second signal if the first subframe and the second subframe overlap in time with more than a first duration.

1. A method comprising:
receiving, by a wireless device, at least one control message comprising configuration parameters of a plurality of cells grouped into a plurality of cell groups comprising a first cell group and a second cell group, wherein:
uplink transmission timing in the first cell group is derived employing a first cell in the first cell group; anduplink transmission timing in the second cell group is derived employing a second cell in the second cell group; transmitting a first signal starting in a first subframe of a cell of the first cell group overlapping in time with a configured transmission of a second signal starting in a second subframe of the second cell group; and dropping transmission of the second signal if a power value is more than an allowable transmission power, wherein a calculation of the power value considers transmission power of the first signal and the second signal if the first subframe and the second subframe overlap in time with more than a first duration.
