SYSTEM AND METHOD FOR OPTIMIZED UTILIZATION OF CODE RESOURCE IN COMMUNICATION NETWORKS

摘要

The present invention provides a kind of method, system and network units to provide the utilization rate of the code resource of enhancing, in the cellular system, it is preferred that in the cellular CDMA-system of ground, wherein base station includes antenna system, and upper limit maximum bit rate is arranged in the spreading factor (SF) of the root channel code of generation several beam in this way. The selection of the spreading factor of the root channel code assumes different wave beams according to the various minimal diffusion factors. Not every emitting radio waves are provided on the uplink for collimated light beam packet scheduling mode, such as PDSCH, there is high or maximum bitrate (low spreading factor) to occur simultaneously. The coordination of packet scheduling, so that only the wave beam of individual beam has high-bit rate transmission period at the same time. Different time slot scheduling balances, therefore they need the code resource of nearly identical amounts.
