In response to determining that the total uplink (UL) interference in a cell has exceeded a predetermined threshold or value, a base station (BS) instructs a plurality of the mobile stations (MS) currently operating in the cell to reduce their current UL power by a predetermined amount (e.g., value of dB or percentage). Such instruction may override conventional closed loop PC instructions to the mobiles in certain embodiments. In such a manner, the UL power reduction is shared in a fairly equal manner by all mobile stations in the cell and overload can be reduced and/or avoided. Subsequently, mobiles stations moving away from the BS toward the cell border may be permitted to increase their UL power so as to maintain a connection. In certain embodiments, the invention is utilized in the context of a code division multiple access (CDMA) system. |
