White Space LTE (WS-LTE) is the communication system operated in the TV white space based on LTE specification. It is intended to mitigate load of commercial cellular systems especially in the area with heavy traffic. By the utilization of current commercial LTE specification , WS-LTE system can harmonize and cooperate with commercial LTE systems, e.g., handover and carrier aggregation among the systems. Besides management by white space database to select the suitable frequency at user’s geolocation, parsameters on WS-LTE eNodeBs and terminals shall also be set and kept updated to the optimal ones to fully use of the limited bandwidth of while space. We are developing several optimization methods according to the user traffic, e.g., switching of duplex mode (FDD and TDD) and dynamic change of uplink and downlink time ratio in TDD mode.
