Techniques for controlling transmit power for a data transmission sent on
multiple data channels, which may be intermittently active, are
described. Each data channel is monitored for activity (e.g., based on an
error correction code, received signaling information, received block
energy, and so on) and deemed to be dormant or not dormant (e.g., based
on the amount of elapsed time since activity was last detected on the
data channel). A signal quality (SIR) target may be maintained for each
non-dormant data channel and updated based on the status of received data
blocks for the data channel. A final SIR target, used for power control
of the data transmission, may be set to the highest SIR target among the
SIR targets for the non-dormant data channels. The final SIR target may
also be updated directly based on the status of received data blocks for
the non-dormant data channels.
