Abstract:

By introducing an adaptive frame structure design to the Time Division Multiple Access (TDMA) based multihop regenerative relay links the transmitting time for each hop can be adjusted. A resource allocation algorithm is proposed for the multihop regenerative relay links with this adaptive frame structure. The objective is to minimize the total transmission power under the constraint that the user's QoS requirement is satisfied. Simulation results show that, compared to the resource allocation algorithm with fixed frame structure, the proposed algorithm can reduce both the total transmission power and the unsatisfying probability of the user.

Key words: communication, mutihop relay links, resource allocation, adaptive frame structure
