Abstract
Certain aspects of the present disclosure relate to methods and apparatus for uplink power control when at least two separate power control algorithms are utilized for adjusting transmission power of uplink transmissions on one or more uplink channels to one or more access points. The method includes transmitting one or more power headroom report (PHR) based on channel and/or system parameters. In addition, methods are presented to match power control for uplink channels when different power control algorithms are used for those uplink channels. Furthermore, methods are proposed to compensate for a switch between reference signals on which the power control algorithms are based.
