Abstract:

To solve the performance deterioration problem of cellular system under high mobility, the application of a train relay station which performs single-user handoff scheme is proposed. Moreover, a dynamic resource reservation scheme based on base station cooperation is presented. Current base station obtains the information of destination base station based on train state information and notifies it to reserve resource for train users. Simulation results show that train communication load affects system performance seriously and performance can be improved significantly through dynamic resource reservation.

Key words: cellular communication, relay station, base station cooperation, resource reservation
