1 Purpose
This contribution suggests SDD text proposal for power control.
2 Proposed Text for 802 .16m Specification
Insert the following text into Physical Layer sub-clause (i.e. Chapter 11 in SDD):
-------------------------------------------------------Start of the text-----------------------------------------------------------11.X Power Control
11.X.1 Uplink Power Control
Uplink power control should be supported to compensate the pathloss, shadowing and fast fading.
Uplink power control can be used to control inter-cell interference level.
BS can transmit necessary information through control channel or message to MSs to support uplink power
control.
The parameters of power control algorithm are optimized on system-wide basis by the BS, and broadcast
periodically.
MS can transmit necessary information through control channel or message to BS to support uplink power
control.
BS can exchange necessary information with neighbor BSs through backbone network to support uplink power

control.
11.X.1.1 Open Loop Power Control
Mobile stations can derive their transmission power according to downlink channel state information and
interference knowledge obtained from downlink signals. Uplink open loop power control uses channel and
interference knowledge to operate at optimum power control settings.
11.X.1.2 Closed Loop Power Control
Base station measures uplink channel state information and interference information using uplink data and/or
control channel transmissions and sends power control command to MSs while minimizing MAC signaling
overhead.
