It's clear that on uplink direction, each ue can dependently control its power sent to node B. But my query is in downlink direction. I'm quite confused at the moment. How can node B control the powe to each connection on DCH channel? Example, when a ue stays at the eage of the coverage, while another one closes to the node B. If the futher one requests to increase the power from node B, does node B just increases the power to those connection or it increases the total power on DCH channel. Meaning that the nearer ue shall receive higher power as well. Or the nearer ue will receive the same power as before on DCH channel? Thanks in advance for all the expert.
