Abstract

Achieving LTE protocol stack on general purpose processor (GPP) faces a crucial issue, in which the computing power of physical (PHY) layer is weaker than that of the embedded prototype and the gap cannot be narrowed in short term. In this paper, we design a compromise method to the issue where medium access control (MAC) can reserve enough time for PHY and the overall performance of the system degrades slightly. In particular, to meet the requirements of the scheduling in advance and the hybrid automatic repeat request (HARQ) timing, we first spread the two requirements into seven demands in scheduling diagram. Then, we can get the final scheduling timing accordance with the seven demands. The theoretical analysis and the functional test results of the prototype are finally provided to verify the feasibility of the MAC timing design.
