A METHOD FOR SOLVING NON-CONTROLLABILITY OF TERMINAL'S POWER SPECTRUM DENSITY IN OFDMA SYSTEM

摘要

The present application provides a method for solving non-controllability of terminal's power spectrum density in OFDMA system, it considers non-controllability of terminal's carrier transmission power as a result of the non-determinacy of carriers number allocated to the terminal; combining AMC, power control and allocation, it solves the problem by introducing the maximum number of allocated carriers. Using the present invention, it controls carrier power of terminal best and makes the terminal transmitting carrier at preset power throughout with largest probability, and it extremely reduces the probability of sudden attenuation of terminal's power spectrum density out of control due to the sum of terminal's preset carriers power exceeding its maximum transmission power, so as to avoid a lot of error in that case, and to avoid power resource waste due to excess constraint of carrier power.
