Design and implementation of the physical layer control system based on TD-LTE baseband chip

In this part, we discuss the physical layer controller scheme of the multi-cores baseband chip, and a physical layer control scheme for TD-LTE mobile terminal baseband chip is proposed. According to the architecture of the baseband chip and the protocol of LTE, the timing base unit is designed. Relying on TBU, under the control of the main control unit l1cp0 and l1cp1, data streams are batched, and we establish the scheduling sequence for physical layer uplink and downlink, and complete timing control and task scheduling among multi-cores baseband chip.
