Due to the limitation of hardware, Soft PHY becomes more and more popular to implement PHY layer. In this paper, we propose a FDD’s multi-threading architecture based on Soft PHY to improve performance for whole eNB PHY layer. Due to the limited timing(1 ms) in PHY layer, we uses Pthread to cooperate with GPU and achieve multitasking for supporting multi users. We let PHY layer have more available CPU timing and much higher throughput to speed up. This paper focuses on the operation of Pthread and the verification of speedup for PHY uplink.
