摘要:
A system for using a predetermined sequence of transmission modes together with power sequencing in order to reduce signaling while improving SNIR levels. Each sequence comprises a vector of transmission modes, where each mode can include a signal constellation, a concatenated channel coding type and rate and, for multiple-input multiple-output systems, one type of matrix modulation. Base transceiver stations can estimate the interference condition for each piece of user equipment and, based on this information, will preferably decide an optimal sequence for each item of user equipment.
