1. the resource allocation methods under the CoMP in the LTE-A system is characterized in that, comprising:

  • Step 1;

    at each terminal, measure all residential quarters at the received power (Reference Signal Received Power is called for short RSRP) of reference signal, wherein RSRP jIt is the Reference Signal Received Power of j residential quarter;

    Step 2;

    find out maximum RSRP value RSRP Max, determine to satisfy RSRP Max-RSRP j

    RSRP ThresholdCooperation cell, residential quarter j is joined in the cooperation set of this terminal, if the number of cooperation cell is 1, this user is single community user, if the number of cooperation cell greater than 1, this user is CoMP user;

    Step 3;

    all RB in the system are carried out resource distribute, initialization i=1, wherein i is RB counting sign;

    Step 4;

    the initialization set omega is the set of all residential quarters in the whole system;

    Step 5;

    the priority of all the CoMP users among the pair set Ω

    sorts from high to low, is designated as set U;

    Step 6;

    the highest user Uc of weights in the pair set U, determine its cooperation collection, if this user'"'"'s CoMP priority, summation greater than single User Priority in the corresponding cooperation cell, just this RB is made as and adopts the CoMP transmission, otherwise this RB is made as single cell transmission, and used cooperation set is removed from set omega;

    Step 7;

    if set omega is not empty, returns step 5 and distribute to the resource of step 6;

    Step 8;

    if i=N RB, N wherein RBBe the RB sum, algorithm finishes, and resource has assigned, otherwise upgrades i, and i=i+1 returns step 4 and distributes to the resource of step 6.
