1. communication equipment, wherein the power of uplink communication between the communication station of one or more distant transmitters and a receiving uplink signal is controlled, communication station comprises an antenna element battle array, each antenna element is coupled to a relevant receiving system, with one group of Signal Processing device that is used for spatial manipulation from a group of received device, spatial manipulation receives weight vector according to one that receives flexible strategy and forms uplink signal, wherein, for a particular remote transmitter(a) initial power of on a normal channel, setting up this particular remote transmitter distribute and on normal channel from specific uplink signal of this particular remote transmitter emission;

  • (b) determine a specific reception weight vector that is used on a space channel of this normal channel with the particular remote transmitter communications;

    (c) receive this specific uplink signal as a group of received signal at antenna element and related receiving apparatus, and with specific this received signal of reception weight vector spatial manipulation, to form a specific received signal;

    (d) estimate the quality of this specific received signal;

    (e) determine a renewal power division that is used for this particular remote transmitter, power division utilizes the received signal quality evaluation to determine;

    With(f) power division of upgrading in this particular remote transmitter applies, this application comprise new uplink signal of emission.
