Patent ID: 7613159

Claim:
A method for determining transmission power levels after admission of a new user in code division multiple access (CDMA) communications, the method comprising: determining an initial estimate of a first transmit power level by a radio network controller (RNC), wherein the first transmit power level is associated with the new user; providing estimates of a second transmit power level by the RNC, wherein the second transmit power level is associated with each of the existing users; generating subsequent estimates for the first transmit power level and the second transmit power level using previous estimates of the first transmit power level and the second transmit power level; and repeatedly generating subsequent estimates with a last repetition's estimates for the first transmit power level and the second transmit power level, the subsequent estimates being generated until the estimated first transmit power level and the estimated second transmit power level converge, wherein convergence of the estimated transmit power levels is determined by the equation  T K + 1 ⁡ ( i ) - T K ⁡ ( i )  T K ⁡ ( i ) ≤ δ wherein T is the transmit power level, i is an index for each user between 1 and M+1, M is a number of existing users, M+1 identifies the new user, K is a number of estimations of the transmit power level for user i, and δ is a convergence parameter.
